DETAILED DESCRIPTION OF THE INVENTION

(22) It is need to preprocess busbars before docking process, a pre-hole is arranged to a docking surface which is for connecting so as to receive a connecting rod, a depth of the pre-hole is slightly greater than half of a connecting rod. A length direction of the busbar is an axial direction of the busbar, a width direction of the busbar is a direction which has a greater dimension in busbar cross section, a thickness direction is a direction which has a less dimension in busbar cross section.

(23) FIG. 1 is a 3d-drawing of a busbars docking platform of the invention, the platform comprises a loading unit 2, an action unit 3, a limit unit 5, a support unit 6, wherein the loading unit 2 has a blind hole 201 on a docking surface for receiving a connecting rod 1, the blind hole 201 has a clearance fit with the connecting rod 1. The action unit 3 is used for impacting the loading unit 2 or a busbar to push the connecting rod 1 into the pre-hole on the busbar. The limit unit 5 is used for stopping the busbar from moving along its length direction.

(24) Referring to FIG. 2, the support unit 6 comprises a first shaft 601, a second shaft 602 parallel to the first shaft 601, a receiving unit 7 slidably connecting with the first shaft 601 and the second shaft 602, a trestle used for supporting the first shaft 601 and the second shaft 602, a pedestal used for supporting the trestle. There are four receiving units 7 in this embodiment, they are a first receiving unit 704, a second receiving unit 705, a third receiving unit 706 and a fourth receiving unit 707. Because the support unit 6 comprises the first shaft 601 and the second shaft 602 parallel to the first shaft 601 and because the receiving unit 7 slidably connects with the first shaft 601 and the second shaft 602, the receiving unit 7 moves smoothly and can receive a busbar of different length by cooperation with a plurality of receiving units 7.

(25) Referring to FIG. 12 and FIG. 13, the receiving unit 7 comprises a mounting plate, the receiving block 701 removably connected to the mounting plate, two sliding blocks removably connected to the mounting plate. The receiving block 701 is arranged at a center position of a length direction of the mounting plate, the two sliding blocks are mirror images to each other concerning a center surface of the length direction of the mounting plate, the sliding block and the receiving block 701 are arranged to opposing side of the mounting plate. Wherein the receiving block 701 is used for receiving the busbar, the receiving block 701 comprises a receiving groove 702 and a limit shaft 703, the receiving groove 702 penetrates through the receiving block 701 to receive the busbar along its width direction, see FIG. 11. The receiving groove 702 is arranged axially with the first shaft 601 and between the first shaft 601 and the second shaft 602, the limit shaft 703 movably inserts into the receiving block 701 for going in and out of the receiving groove 702 to stop the busbar from moving along its width direction. Because the receiving groove receives the busbar along width direction of the busbar, it is unhindered for an operator to put the busbar into the receiving groove over the docking platform, such arrangement increases assembly efficiency. The limit shaft 703 arranged to the receiving unit stops the busbar from moving along width direction during impact process, such arrangement is good for the connecting rod to assemble successfully.

(26) Referring to FIG. 2, the limit unit 5 comprises a first threaded rod 501 and a second threaded rod 502 both parallel to the first shaft 601, a limit block 503 removably connecting with the first threaded rod 501 and the second threaded rod 502, a connecting block 504 connecting with the first threaded rod 501 and the second threaded rod 502 and cooperating with the action unit 3.

(27) Referring to FIG. 8, the action unit 3 comprises a first base 301 fixedly connecting between the first shaft 601 and the second shaft 602, a second base 302 fitting with the connecting block 504 of the limit unit 5, an end portion 303 outwardly extending from the first base 301 to impact the busbar, and a driving mechanism housed in the first base 301 and the second base 302 to drive the end portion 303. Because the limit block 503 of the limit unit 5 well touches an end of the busbar and the connecting block 504 of the limit unit 5 well touches the second base 302 of the action unit 3, the busbar can not move along the direction of movement of the connecting rod 1 when the connecting rod 1 inserts into the busbar, such arrangement achieves a successful assembly of the connecting rod. The driving mechanism comprises a spring, an operation member used for compress the spring to store energy, a first member used for keeping the spring at a first compression state, a second member used for keeping the spring at a second compression state, a third member used for keeping the spring at a third compression state, a first release member used for releasing the spring to move from the first compression state to the second compression state, and a second release member used for releasing the spring to move from the second compression state to the third compression state. The end portion 303 of the action unit 3 is at a retraction state when the spring is at the first compression state or at the third compression state, see FIG. 9. The end portion 303 of the action unit 3 is at an exsertion state when the spring is at the second compression state, see FIG. 8. The operation member connects a handle arranged out of the first base 301 and out of the second base 302, the spring is compressed by the operation member when the handle is turned.

(28) Referring to FIG. 10, the action unit 3 further comprises a first button 305 and a second button 306, to trigger the first button 305 is to make the first release member act, the spring moves from the first compression state to the second compression state.

(29) Referring to FIG. 15, the loading unit 2 has an identical outline to a first busbar 101 or a second busbar 102, the blind hole 201 is arranged on a docking surface of the loading unit 2 and extends along a length direction of the loading unit 2, an effective depth of the blind hole 201 is half of axial length of the connecting rod 1, see FIG. 16. The blind hole arranged to the loading unit has a clearance fit with the connecting rod 1, such arrangement is convenient for the loading unit 2 to remove for next assembly process after that the connecting rods 1 are assembled into the busbar and increases reusability of the loading unit 2. Because the loading unit 2 has an identical outline to the busbar, the loading unit 2 is also applicable for the receiving unit 2 used for receiving the busbar, such arrangement increases interoperability of the loading unit 2.

(30) Referring to FIG. 3, the busbars docking platform has four receiving units 7, they are a first receiving unit 701, a second receiving unit 702, a third receiving unit 703 and a fourth receiving unit 704. The first receiving unit 701 is used for receiving the loading unit 2 and both the second receiving unit 702 and the third receiving unit 703 are used for receiving the first busbar 101 at a stage of assembling the first busbar 101. Both the first receiving unit 701 and the second receiving unit 702 are used for receiving the first busbar 101 and both the third receiving unit 703 and the fourth receiving unit 704 are used for receiving the second busbar 102 at a stage of assembling the second busbar, see FIG. 4.

(31) Referring to FIG. 2, the first threaded rod 501 is removably connected by two first nuts clamping the limit block 503, the second threaded rod 502 is removably connected by two second nuts clamping the limit block 503, the first threaded rod 501 is connected by two third nuts clamping the connecting block 504, the second threaded rod 502 is connected by two fourth nuts clamping the connecting block 504. The limit block 503 is clamped at different positions on the threaded rod by adjusting nuts at different positions on the threaded rod to limit busbars of different length, such arrangement increases usability of the busbars docking platform for busbars of different length.

(32) The embodiment of the invention also discloses an operation method of the busbars docking platform, the operation method comprises following steps.

(33) S1 Trigger the first button 305 of the action unit 3 to make the first release member act and to keep the end portion 303 of the action unit 3 at the exsertion state, check positions of the limit shafts 703 arranged to the first receiving unit 704, the second receiving unit 705, the third receiving unit 706 and the fourth receiving unit 707, draw each limit shaft 703 out of the corresponding receiving unit 7 to vacate the receiving groove 702 if the limit shaft 703 inserts into the receiving groove 702.

(34) S2 Put the first busbar 101 in the receiving groove 702 of the second receiving unit 705 and in the receiving groove 702 of the third receiving unit 706 in a way that the docking surface of the busbar faces the action unit 3, insert the limit shaft 703 into the second receiving unit 705 and insert the limit shaft 703 into the third receiving unit 706, arrange the limit shaft 703 to insert into the receiving groove 702, see FIG. 19.

(35) S3 Put the loading unit 2 in the receiving groove 702 of the first receiving unit 704, the loading unit 2 is only used for determining a position of the limit block 503 of the limit unit 5 at present, so it is no need for the loading unit 2 to receive the connecting rod 1.

(36) S4 Arrange a docking surface of the first busbar 101 to touch a docking surface of the loading unit 2, arrange a surface of the loading unit 2 away from the docking surface to touch the end portion 303 of the action unit 3, adjust and fasten the limit block 503 of the limit unit 5 to arrange the limit block 503 to touch a surface away from the docking surface of the first busbar 101, see FIG. 3.

(37) S5 Remove the loading unit 2 from the busbars docking platform.

(38) S6 Load the connecting rod 1 to the loading unit 2, see FIG. 14, put the loading unit 2 already loaded with the connecting rod 1 in liquid-nitrogen for deep-freezing in such a way that the connecting rod 1 is completely covered by the liquid-nitrogen for 5 minutes.

(39) S7 Trigger the second button 306 of the action unit 3 to make the second release member act so as to retract the end portion 303 of the action unit 3 and to keep the end portion 303 at a retraction state.

(40) S8 Turn the handle 304 of the action unit 3 to compress the spring of the driving mechanism and to keep the spring at a first compression state, heat the docking surface of the first busbar 101 to reach a temperature of over 200 celcius degrees.

(41) S9 Take the loading unit 2 loaded with the connecting rod 1 out of liquid-nitrogen, put the loading unit 2 in the receiving groove 702 of the first receiving unit 704, arrange the surface away from the docking surface of the loading unit 2 against the end portion 303 of the action unit 3, insert the limit shaft 703 into the first receiving unit 704 to insert the limit shaft into the receiving groove 702, see FIG. 21.

(42) S10 Trigger the first button 305 of the action unit 3 to make the first release member act so as to exsert the end portion 303 of the action unit 3 to impact the loading unit 2 so that the connecting rod 1 on the loading unit 2 inserts into a pre-hole of the first busbar 101, see FIG. 22 and FIG. 17. Because a deep-freezing process for the connecting rod 1 and a heat process for the pre-hole of the busbar change assembly relation between the connecting rod 1 and the pro-hole of the busbar from interference fit to clearance fit, it is only need to impact the connecting rod quickly into the pre-hole when the connecting rod 1 is assembled, it is no necessary for the end portion 303 of an action unit 3 to have much thrust force. Clearance fit between the connecting rod 1 and the pre-hole of the busbar after heat and freezing process combined with chamfer on an end surface of the connecting rod 1 also can reach successful assembly between the connecting rod 1 and the pre-hole under high speed impact of the action unit 3 even if coaxiality between the connecting rod 1 and the pre-hole is not very good. Arrangement that a plurality of connecting rods 1 can be loaded simultaneously to the loading unit 3 increases docking efficiency for busbars. Because the end portion 303 of the action unit 3 impacts the loading unit 2 other than the connecting rod 1, hypothermia of the connecting rod 1 can not be effected by impact from the action unit 3, the connecting rod 1 still keeps at shrinkage state so as to inserts easily into the pre-hole of the busbar.
