Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to a fixture for spring processing. Background Technique

[0002] A spring is a mechanical part that utilizes elasticity. A part made of elastic material deforms under the action of an external force and returns to its original state after the external force is removed. It is generally made of spring steel. Springs are complex and diverse in types. According to the shape, there are mainly helical springs, scroll springs, leaf springs, and special-shaped springs. A spring fixture is used to clamp and fix the spring during the spring production process, so as to facilitate the processing of the spring.

[0003] For example, the publication number: CN218775583U, named "A Fixture for Spring Processing", includes a bottom plate and a support frame. The support frame is fixedly installed at the upper end of the bottom plate, and further includes: a clamping component for positioning and clamping the spring. The clamping component is installed on the support frame. By sleeving the spring on the positioning support rod, the turntable and the clamping plate are used for guiding, squeezing and stretching, so that the spring will not shift during the compression process. By connecting a motor to one end of the positioning support rod, the spring can be driven to rotate. By using a fixed clamping screw and a fixed screw for the spring, the two ends of the spring can be clamped and limited, so as to meet the multi-form requirements of the spring.

[0004] However, when the existing spring fixture fixes the spring end through a screw, it is difficult to change the fixing position according to different spring sizes and coil distances, resulting in limitations of the fixture and affecting the user experience. Therefore, it does not meet the existing requirements, and for this reason, we propose a fixture for spring processing. Content of the Utility Model

Springs with different coil distances and sizes and thicknesses can be positioned at the assembly holes 20 at different positions by adjusting the screw 15 in a lifting manner, so as to effectively handle clamping operations for different springs.

[0023] Among them, the clamping and limiting member 3 includes a frame 11. On the inner wall of the cavity of the frame 11, slideways 12 are symmetrically arranged on the left and right. Above the slideways 12, a limiting frame 13 is provided. Between the slideways 12 and the limiting frame 13, a lifting slider 14 is arranged. A screw rod 15 is installed in the opening on the outer wall of the lifting slider 14. One end of the screw rod 15 is provided with a turning handle 16. The assembly component 4 includes a support column 18. A sleeve 19 is sleeved on the outer wall of the support column 18. A plurality of assembly holes 20 are provided on the outer walls of the sleeve 19 and the support column 18. And the other end of the screw rod 15 is combined with the support column 18 through the assembly hole 20. The lifting slider 14 is restricted between the slideways 12 and the limiting frame 13 to prevent the lifting slider 14 from separating and falling off at the slideways 12. The lifting slider 14 is used for lifting and moving at the slideways 12. During the movement, it drives the adjustment of the assembly height at the screw rod 15, so that the screw rod 15 can align with the assembly holes 20 at different positions for positioning. The end of the spring is sleeved on the sleeve 19. After being sleeved, it is restricted between the spring coils by the way of rotation and insertion of the screw rod 15, so that the spring is restricted and fixed at that place. The multi-group annular distribution setting can position the spring in multiple directions and improve the clamping effect.

[0024] Please refer to Figure 2 、 Figure 4 . A thread groove 6 is opened at the middle position on the outer wall of the fixture chuck 1.

[0025] Please refer to Figure 2 、 Figure 3 . Limiting grooves 8 are opened on the inner walls on both sides of the sliding groove 7. The displacement component 5 includes a front and rear slider 9 arranged in the sliding groove 7. Limiting blocks 10 are arranged on both sides of the front and rear slider 9, and the limiting blocks 10 extend into the limiting grooves 8. The front and rear slider 9 is used for sliding back and forth in the sliding groove 7. By sliding back and forth, it drives the displacement of the frame 11 to adjust the position of the screw rod 15. When clamping, the screw rod 15 is moved forward close to the support column 18, which is convenient for the subsequent alignment of the screw rod 15 with the assembly hole 20 for limiting operation. When moving backward, it is convenient for users to remove the spring at the support column 18. At the same time, it is also convenient for users to remove the entire support column 18 for replacement operation. The setting of the limiting groove 8 and the limiting block 10 is used to restrict the front and rear slider 9 to prevent it from separating from the sliding groove 7.

[0026] Working principle: When in use, the displacement of the frame 11 is driven by the front and rear slider 9. When clamping, the screw rod 15 is moved forward close to the support column 18, which is convenient for the subsequent alignment of the screw rod 15 with the assembly hole 20 for limiting operation;

[0027] The lifting slider 14 is used for lifting and moving at the slideway 12. During the movement, it drives the adjustment of the assembly height at the screw rod 15, enabling the screw rod 15 to align with the assembly holes 20 at different positions for positioning. The end of the spring is sleeved on the sleeve 19. After sleeving, it is restricted between the spring coils by the rotation and insertion of the screw rod 15, so that the spring is restricted and fixed at this position;

[0028] During disassembly, the screw rod 15 is driven to rotate outwards by the rotating handle 16, so that it is separated from the assembly hole 20. The front and rear slider 9 drives the clamping and limiting member 3 to displace backwards, enabling the user to remove the spring sleeved on the sleeve 19. Moreover, by grasping and rotating the support column 18, the threaded seat 17 can be separated from the threaded groove 6, enabling the user to disassemble, assemble and replace the assembly component 4.
