DETAILED DESCRIPTION OF THE INVENTION

[0028] Depicted in FIG. 3 and FIG. 4 is a vice quick change base with improved structure, comprising: a base body (1), with the center of its bottom configured with a first holding groove (11), wherein, the two ends of the first holding groove (11) are respectively configured with a second holding groove (12) joint and communicated with the first holding groove (11), the inside of the second holding groove (12) is configured with a plurality of quick-change coupler positioning hole (13) going vertically through the base body (1); a plurality of quick-change couplers (2), configured to match the quick-change coupler positioning hole (13), with its one end inserted into the quick-change coupler positioning hole (13), and the other end used for coupling with a vice, the quick-change coupler (2) having a recess (21); a moveable block set (3), made up of a first moveable block (31) and a second moveable block (32) configured to respectively match the second holding groove (12) and capable of moving toward or away from each other along the second holding groove (12), wherein, the sides of the first moveable block (31) and the second moveable block (32) facing the first holding groove (11) are respectively configured with a through hole (33), and a cross-hole nut (331) is configured in the direction perpendicular to the through hole (33); and a lead screw (4), configured inside the first holding groove (11), going through the through hole (33) and screwed into the cross-hole nut (331); characterized in that: the bottoms of the first moveable block (31) and the second moveable block (32) are respectively configured with a moveable block positioning base (5), the side of the moveable block positioning base (5) facing the quick-change coupler (2) is protruded with an extended positioning plate part (51) configured to match the quick-change coupler (2), one end of the extended positioning plate part (51) is protruded with a pushing block (511) in the direction facing the quick-change coupler positioning hole (13). Furthermore, the first moveable block (31) and the second moveable block (32) respectively have a curved stopping block (34) to fit into the recess (21) at the position corresponding to the recess (21) of the quick-change coupler (2).

[0029] In the structure described above, the inside of the second holding groove (12) is separated to form a position limiting space (121) at the position corresponding to the extended positioning plate part (51). The position limiting space (121) is communicated with the second holding groove (12), so that the position limiting space (121) can hold the extended positioning plate part (51) and limit its movement.

[0030] In the structure described above, at the position corresponding to the second holding groove (12), the base body (1) is further configured with a cover (6) to close the second holding groove (12).

[0031] Through locking and fixation of the cover (6), the components such as the moveable block set (3) and the moveable block positioning base (5) can be locked and mounted inside the base body (1). Meanwhile, the cover (6) can prevent dust or contaminants from entering the second holding groove (12).

[0032] In the structure described above, the base body (1) is further configured with a plurality of mounting holes (7), for the base body (I) to be fixed on the machine workbench.

[0033] Referring to FIG. 5 to FIG. 7, the bottom end of the quick-change coupler (2) abuts the extended positioning plate part (51). When the lead screw (4) rotates clockwise, the first moveable block (31) and the second moveable block (32) will move toward the quick-change coupler (2), so that the curved stopping block (34) on the first moveable block (31) and the second moveable block (32) will fit into the recess (21) on the quick-change coupler (2), thus clamping the quick-change coupler (2) tightly inside the quick-change coupler positioning hole (13); On the contrary, when the lead screw (4) rotates anticlockwise, the first moveable block (31) and the second moveable block (32) will move away from the quick-change coupler (2), driving the moveable block positioning base (5) to move simultaneously. As a result, the pushing block (511) protruding out of the moveable block positioning base (5) will push the bottom end of the quick-change coupler (2), thus pushing the quick-change coupler (2) out of the quick-change coupler positioning hole (13). Now, the operator can quickly remove and replace the vices. The quick-change function is thus realized.

[0034] As disclosed in FIG. 5 and FIG. 6, the first moveable block (31) and the second moveable block (32) are in a trapezoidal shape, with its long side facing outward and its short side facing inward. Its two sloping sides are protruded with an outward curved stopping block (342) and an inward curved stopping block (343) separated by, a stage part (341).

[0035] In the structure described above, when rotating the lead screw (4) to move the first moveable block (31) and the second moveable block (32) toward the quick-change coupler (2), the conic sloping edges of the outward curved stopping block (342) and the inward curved stopping block (343) will be directly inserted into the recess (21) of the quick-change coupler (2), and push the quick-change coupler (2) to be locked. In this way, the vices (100) can be tightly positioned and mounted, ensuring stability and safety of the vices (100).

[0036] Referring to FIG. 7 to FIG. 9, the pushing block (511) also has a guide surface (512). The guide surface (512) can be an inclined surface or curved surface [not disclosed in the drawing]. Thus, when the pushing block (511) pushes the bottom end of the quick-change coupler (2), the guide surface (512) will guide the quick-change coupler (2), so that the quick-change coupler (2) will be pushed out along the guide surface (512). On the contrary, when the pushing block (511) moves away from the quick-change coupler (2), the quick-change coupler (2) can enter the base body (I) along the guide surface (512). In this way, the voices can be easily assembled and replaced. The whole operation becomes more convenient.
