Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary processing equipment of linear motors, in particular to a U-shaped linear motor combined magnet installation fixture. Background Art

[0002] After the magnets of the U-shaped linear motor are pasted to the stator base plate, a pair of stator base plates and a single stator base bar need to be assembled to form a U-shaped structure. During this process, as the pair of stator base plates approach each other, the mutual attraction between the magnets gradually increases, and there is a risk of pinching hands, or collision between the stator base plates or between the stator base plates and the stator base bars, causing the magnets to slip or fall off.

[0003] Although in the prior art, tooling is also used to realize the assembly of the stator base plate and the stator bottom bar, it is impossible to control the spacing position and merging according to the mutual force of the magnets, and it is also impossible to adapt to magnets of more specifications and sizes, which is not conducive to the functionality of the fixture installation.

[0004] To this end, we propose a U-shaped linear motor and magnet mounting fixture. Utility Model Content

[0020] (III) Beneficial effects

[0021] The utility model provides a U-shaped linear motor combined magnet installation fixture, which has the following

[0022] Beneficial effects:

[0023] 1. The positioning slot formed by the magnetic partition, the magnetic stopper and the magnetic base supports the stator base plate to which the magnet is pasted. The ball screw drives the sliding module to move along a straight line toward the fixed module on the other side to adjust the relative position of the two stator base plates. In the process of the two stator base plates approaching each other and splicing, the staff does not need to hold the stator base plates by hand, thereby avoiding the risk of pinching the hands. At the same time, the stator base plate and the magnet on the moving side are restricted by the cooperation of the sliding seat and the ball screw, and the ball screw is further constrained by the locking block, which can effectively avoid the collision of the stator base plates on both sides during the splicing process, thereby preventing the magnet from slipping and falling off.

[0024] 2. The magnetic base and workstation support plate of the fixed module and the sliding module adopt a detachable structure, which can adapt to the clamping of positioning base plates, magnets and positioning bottom strips of different specifications and sizes as needed. At the same time, the distance between the fixed module and the sliding module is adjusted by a ball screw, which can control the spacing position and merging according to the mutual force of the magnets, thereby facilitating the functionality of the fixture installation.
