The top of the displacement fixture 1 is slidably connected to an assembly frame, and the upper surface of the assembly frame is provided with a groove 9. The groove opening of the groove 9 is slidably connected to a clamping plate 5 and a clamping plate 7, respectively. The inner sides of the clamping plate 5 and the clamping plate 7 are both provided with a horizontal groove 8. The groove opening of the horizontal groove 8 is slidably connected to a placement plate 6. A vertical fixture 2 and a horizontal fixture 4 are respectively provided on one side of the displacement fixture 1.

[0022] A connecting plate 13 is fixedly connected to the pushing end face of the vertical tooling 2. A lead screw cylinder is fixedly connected to the lower surface of the connecting plate 13, and a slider 14 is fixedly connected to the outer wall of the lead screw cylinder through a connecting rod.

[0023] The groove of the slider 14 is slidably provided with a slide rail 15, and the inner cavity of the lead screw cylinder is threadedly connected to a drive shaft 12. The power input end of the drive shaft 12 is equipped with a motor 11.

[0024] A mating block 17 is fixedly connected to the front end of the transverse tooling 4. A bearing mounting box 10 is fixedly connected to the end of the mating block 17 away from the transverse tooling 4. A grinding disc mounting shaft 16 is installed at the front end of the bearing mounting box 10.

[0025] The bearing mounting box 10 houses a drive motor for rotating the grinding disc mounting shaft 16.

[0026] A power distribution cabinet 3 is installed on one side of the vertical fixture 2 and the horizontal fixture 4.

[0027] The working principle of this utility model is as follows:

[0028] In use, an assembly frame is installed on the top of the displacement fixture 1 for conveying the spring;

[0029] Specifically: A groove 9 is opened on the upper frame surface of the assembly frame for the sliding of clamping plate 1 5 and clamping plate 2 7. The size of the transverse groove 8 at the groove opening of the placement plate 6 is controlled by adjusting the distance between clamping plate 1 5 and clamping plate 2 7.
