Technical Field
[0001] The utility model relates to the technical field of jigs, in particular to the technical field of jigs for spring steel wires. Background Technique
[0002] A jig refers to a mechanical device used to fix and position workpieces in industrial production. It usually consists of a clamping device and a supporting device. The clamping device can firmly fix the workpiece on the workbench, and the supporting device can provide the necessary supporting force to ensure that the workpiece will not move or loosen during the processing. In the process of manufacturing springs, grooving is sometimes necessary. A spring steel wire grooving jig is a clamping and positioning tool specifically designed for grooving operations on spring steel wires. However, for spring steel wires, due to their good elasticity, when using the jig to clamp, elastic deformation may occur, resulting in processing errors. Content of the Utility Model

[0005] Further, a sliding column is provided on the long block, the sliding column is stuck in the long groove of the long groove plate, and the long groove plate is fixedly connected to the fixed seat.
[0006] Further, the long groove plate uses 45# steel as the material and is processed by quenching and tempering treatment.
[0007] Further, at least five long grooves are provided on the long groove plate, the middle long groove is vertical, the long grooves on both sides are inclined, and the inclination degrees of the long grooves from the middle to both sides increase in turn.
[0008] Further, a turning handle is provided on one side of the screw rod.
[0009] Further, a handle is provided on each side of the fixed seat.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] The utility model realizes the synchronous movement of multiple long blocks through the combination of a lead screw slider and a guide rail, making the clamping operation of the fixture convenient. At the same time, the multiple long blocks clamp each segment of the spring, making the clamping more stable. After clamping, the elastic deformation of the spring is reduced, which is beneficial to the smooth progress of grooving processing. Brief Description of the Drawings

[0017] To further elaborate on the technical means and effects adopted by the utility model to achieve the predetermined utility model purpose, the following combines the drawings and preferred embodiments to detail the specific embodiments, structures, features and their effects of the utility model as follows.
[0018] Please refer to Figures 1 to 3 , this embodiment provides a grooving fixture for spring wire, including: a fixed seat 2, a pair of symmetrically arranged guide rails 3 are provided on the fixed seat 2, a slider 4 is provided on the guide rail 3, an optical axis 14 is provided on the slider 4, and the optical axis 14 penetrates through 7 juxtaposed long blocks 10. A fixed block 7 is provided on the middle long block 10, a lead screw nut 6 is fixedly connected to the fixed block 7, a lead screw 8 is provided in the middle of the lead screw nut 6, and the lead screw 8 is threadedly connected to the lead screw nut 6. The slider 4 and the guide rail 3 limit the degree of freedom of the optical axis 14 so that it can only move up and down. When the lead screw 8 rotates, the optical axis 14 and the long block 10 move up and down.
[0019] A slide post 11 is provided on the long block 10, and the slide post 11 is stuck in the long groove of the long groove plate 9, and the long groove plate 9 is fixedly connected to the fixed seat 2.
[0020] It should be noted that the long groove of the long groove plate 9 has at least five long grooves, the middle long groove is vertical, the long grooves on both sides are inclined, and the inclination degree of the long grooves from the middle to both sides increases in turn.
[0021] During the up and down movement of the long block 10, due to the space limitation of the slide post 11 in the long groove plate 9, the 7 long blocks 10 move left and right inwards or outwards simultaneously.
[0022] The long groove plate 9 is made of 45# steel and processed by quenching and tempering treatment. The wear resistance of the long groove plate 9 is enhanced, and the wear caused by the long-term friction of the sliding column 11 in the long groove plate 9 is reduced, improving the service life.
[0023] One side of the lead screw 8 is provided with a turning handle 1. By turning the turning handle 1 by hand, the operation is used to rotate the lead screw 8 to achieve transmission, and the operation is convenient.
[0024] A handle 5 is provided on each side of the fixed seat 2. It is convenient to carry.
[0025] Working principle:
[0026] Place the device flat on the workbench surface. The holes at the four corners of the fixed seat 2 can be locked with screws to make the device difficult to move. Rotate the turning handle 1 in the clockwise direction to widen the distance between the seven long blocks 10, put the spring 12 in, and make each section of the spring 12 get stuck between the gaps of the long blocks 10. Then rotate the turning handle 1 in the counterclockwise direction to reduce the distance between the seven long blocks 10 and slowly clamp the spring 12. Then perform subsequent grooving operations on the spring 12. Due to the existence of multiple long blocks 10, each section of the spring 12 can be clamped, making the clamping more stable. After clamping, the elastic deformation of the spring is reduced.
[0027] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to be equivalent embodiments within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
