DETAILED DESCRIPTION

[0033] Referring to FIGS. 1-3, the present disclosure provides a technical solution: a fixture for sticking balance blocks to the surface of a hub includes a base 1, in which a fixed plate 2 is welded to one side of the upper end of the base 1, a slide rail 3 butted to the fixed plate 2 is connected to the other side of the base 1 by bolts, a sliding block 4 is connected to the slide rail 3 in a sliding manner, the fixed plate 2 and the sliding block 4 are respectively connected with a first roller 5 and a second roller 6 of the same type by bearings, the sliding block 4 is in fit connection with the second roller 6 to adjust the spacing between the first roller 5 and the second roller 6 so as to adapt to hubs of different diameters, each of the first roller 5 and the second roller 6 is sleeved with a rubber sleeve 7 of the same specification, the rubber sleeves 7 are used for protecting the surface of the hub to prevent the surface of the hub from being scratched by burrs on the surfaces of the rollers, a support table 8 is mounted under the base 1, fixed blocks 9 corresponding to the support table 8 are welded to the sides of the base 1, the support table 8 is connected with a connecting block 10, a corresponding sprocket 11 is mounted at each of the connecting block 10 and the ends of the first roller 5 and the second roller 6, and the three groups of sprockets 11 are driven by a chain 12 to drive the surface of the hub to rotate so as to facilitate the sticking of the balance block.

[0034] Specifically, a handle bolt 14 is in threaded connection to the middle of each fixed block 9, at least two corresponding groups of handle bolts 14 and fixed blocks 9 are provided, the end surface of the base 1 is adjusted to balance via the handle bolts 14 mounted on the fixed blocks 9 to prevent the surface of the hub from toppling.

[0035] Specifically, a handle 15 is mounted at the other end of the first roller 5 and located on the outer side of the base 1, the handle 15 is used for driving the first roller 5 to rotate, and the chain 12 is driven to connect the second roller 6 via the sprockets 11 to maintain synchronous rotation of the first roller 5 and the second roller 6.

[0036] Specifically, a bolt rod 16 is connected to the upper end of the sliding block 4 in a penetrating manner, the slide rail 3 is provided with a positioning hole 17 corresponding to the bolt rod 16, and the bolt rod 16 fits with the positioning hole 17 in the slide rail 3 to fix the sliding block 4 so as to prevent the sliding block 4 from shaking when the balance block is stuck.

[0037] Specifically, the bottom of the support table 8 clamps a spring 18 under the connecting block 10 to ensure the chain 12 in a tensioned state.

[0038] Working principle: the sliding block 4 is moved during use, the spacing between the first roller 5 and the second roller 6 is adjusted to adapt to the hubs of different diameters, then the sliding block is fixed by the bolt rod 16, the sliding block 4 pulls the connecting block 10 via the chain 12 connected to the sprockets 11, the spring 13 mounted at the bottom of the support table 8 pulls the connecting block 10 such that the sprocket 11 mounted on the connecting block 10 is always clamped on the chain 12 to maintain the tensioned state of the chain 12 and ensure the drive reliability of the rollers, then the handle bolt 14 is rotated, the end surface of the base 1 is adjusted to be horizontal via the handle bolt 14 mounted on the fixed block 9 to maintain the hub in a horizontal state, the handle 15 is rotated after a balance block at the lower end of the hub is stuck, and the sprockets 11 fit with the drive of the chain 12 to maintain the synchronous rotation of the first roller 5 and the second roller 6 such that the hub rotates to stick a balance block on the other side, instead of rotation of the hub.
