Description

Technical Field

[0001] The utility model relates to the field of jigs, in particular to a linkage sliding device. Background Art

[0002] In the process of machining automotive parts, since the automotive parts themselves are relatively large, it is often necessary to use positioning jigs for positioning in order to smoothly complete subsequent processing, assembly and other processes. The existing positioning jigs generally position by setting clamping mechanisms on each end face of the automotive parts. However, because setting multiple clamping mechanisms requires multiple people to operate or one person to frequently travel back and forth between each clamping mechanism to lock and unlock the clamping mechanisms, it is very inconvenient. Moreover, operating each clamping mechanism individually will, to a certain extent, cause the automotive parts to shift, be off-center, etc., resulting in inaccurate positioning, which in turn affects the accuracy of subsequent process machining and assembly, and ultimately leads to defective automotive parts. Therefore, it greatly troubles the automotive parts processing industry.

[0003] Therefore, it is urgent to develop a new technology or positioning device to solve the above problems. Summary of the Utility Model

[0046] When the utility model is in use:

[0047] When the drive arm 232 is pulled in the first direction to push the second connecting rod 242 to move in the direction close to the rotating unit 21, the turntable 214 rotates under the drive of the second connecting rod 242 until the limit post 213 abuts against one side wall of the limit hole 215.

Finally, the clamping part 226 of the clamping block 225 abuts against the product 100 and fixes the product 100 on the linkage sliding device for processing operations.

[0048] When the drive arm 232 is pulled in the second direction to pull the second connecting rod 242 to move away from the rotating unit 21, the turntable 214 rotates under the drive of the second connecting rod 242 until the limit post 213 abuts against the other side wall of the limit hole 215. Among them, the turntable 214 on one side rotates counterclockwise around the first rotating shaft 212, and the turntable 214 on the other side rotates clockwise around the first rotating shaft 212. At the same time, the rotation of the turntable 214 drives the first connecting rod 241 between the turntable 214 and the swing arm 26 to move in the direction close to the rotating unit 21, further pulling the swing arm 26 to rotate around the second rotating shaft 281 of the fourth support seat 28, and the upper end of the swing arm 26 pulls the fixed block 224 in the direction away from the rotating unit 21 through the third connecting rod 243. Furthermore, the fixed block 224 drives the clamping block 225 to move along the slide rail 222 in the direction away from the rotating unit 21. Finally, the clamping part 226 of the clamping block 225 disengages from the product 100 and releases the product, so as to remove the product 100 from the linkage sliding device.

[0049] The linkage sliding device provided by the present utility model operates the driving unit 23 to drive the rotation of the rotating unit 21, and then the rotating unit 21 synchronously drives the symmetrically arranged sliding units 22 to synchronously displace, so as to realize the synchronous positioning of the relative two sides of the product 100.
