[0001] This utility model relates to the field of hairspring precision machining technology, specifically to a high-efficiency, high-quality hairspring copper seat pressing and blanking tooling. Background Technology

[0002] A hairspring is an elastic element used in instrument panels. Inside the instrument panel, it acts as a spring, driving and resetting the pointers.

[0003] In the process of hairspring machining, the hairspring needs to be combined with the copper holder. After the combination is completed, the copper holder and copper wire need to be pressed again to achieve a strong snap-fit ​​relationship between the copper holder and the hairspring, ensuring that the center of the hairspring is stable. The existing hairspring copper holder pressing process uses a pressing machine for riveting. A positioning protrusion is set on the tooling table to snap the center of the copper holder into it. Then, the riveting cylinder is activated to rivet the surface of the copper holder, thereby ensuring that the copper holder deforms under pressure and is fixed to the surface of the hairspring.

[0004] In the existing riveting process for hairspring copper seats, only a single workpiece can be riveted. In the riveting process, a large number of workpieces need to be processed at the same time. Processing each workpiece one by one will significantly reduce the efficiency of riveting, resulting in problems such as excessive processing time and delays in the production schedule. Therefore, the existing riveting process for hairspring copper seat workpieces has the problem of low processing efficiency for a single workpiece. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0026] refer to Figure 1-4 A blanking table 1 is set up for processing and blanking operations. A drive device 2 and a pressing device 3 are respectively set on the two lower tables. The drive device 2 can rotate to enhance the pressing effect and perform blanking flipping. The pressing device 3 can press multiple hairspring workpieces at the same time to improve riveting efficiency.

[0027] refer to Figure 1-4The driving device 2 includes a driving linear module 21 and a connecting plate 211 fixedly connected to the output end of the driving linear module 21. A rack structure 22 is fixedly connected to one end of the connecting plate 211. The rack structure 22 is a strip-shaped structure with several meshing tooth grooves. A gear structure 11 is rotatably connected to the unloading table 1. The rack structure 22 and the gear structure 11 mesh, and the movement of the rack can drive the gear structure 11 to rotate. A rotating shaft 23 is fixedly connected to one end of the gear structure 11. A placement plate 24 that rotates with the rotating shaft 23 is fixedly connected to the rotating shaft 23. The rotation of the gear drives the rotating shaft 23 to rotate and... The movable placement plate 24 is flipped, and several placement grooves 241 are opened on the placement plate 24. The placement grooves 241 place the hairspring workpiece. The bottom surface of the placement groove 241 has flexible deformation properties. Its ground is made of rubber material, which has deformation properties and flexibility. When the bottom is resisted, it will deform upward. The driving device 2 also includes a strip-shaped slide 25 fixedly connected to the unloading table 1. A strip-shaped slider 221 extends from the bottom end of the rack structure. The strip-shaped slider 221 extends into the strip-shaped slide 25 and slides, which restricts the sliding direction of the rack structure 22, so that the rack structure 22 can only slide along the length direction of the strip-shaped slide 25.

[0028] refer to Figure 1-4 A receiving plate 231 is fixedly connected to the rotating shaft 23. The receiving plate 231 is fixedly connected to one side of the placement plate 24. The receiving plate 231 can increase the rotation radius of the placement plate 24. Several abutting rods 12 are fixedly connected to the unloading table 1. The position of the abutting rods 12 corresponds to the center position of the placement tank 241. They can abut against the bottom surface of the placement tank 241 and drive the bottom surface of the flexible placement tank 241 to deform. A limiting block 242 is fixedly connected to the inner bottom surface of the placement tank 241. The limiting block 242 is used for the sleeve and fixation of the copper base. The center of 2 and the center of the abutment rod 12 are coaxial, ensuring that the copper seat can be pushed upward when the bottom surface of the placement tank 241 is deformed. A rotating base 13 is fixedly connected to the unloading table 1. A rotating hole 131 is opened on the rotating base 13. The rotating shaft 23 passes through the rotating hole 131. An air blowing port 243 is opened on the inner bottom surface of the placement tank 241. A unloading collection tank 14 that cooperates with the air blowing port 243 is fixedly connected to the side of the unloading table 1 away from the pressing base 32. During unloading, the workpiece is blown into the unloading collection tank 14 by airflow into the air blowing port 243.

[0029] refer to Figure 1-4The pressing device 3 includes several pressing heads 31 arranged in an array. The pressing heads 31 are positioned directly above each placement groove 241. The pressing heads 31 can extend into the placement groove 241 and abut against the spiral spring workpiece inside the placement groove 241. The pressing device 3 also includes a pressing base 32 fixedly connected to the surface of the unloading table 1. A pressing cylinder 33 is fixedly connected to the top of the pressing base 32. The output end of the pressing cylinder 33 passes through the top surface of the pressing base 32 and is fixedly connected to a multi-pressing plate 34 at the other end. The array of pressing heads 31 are all fixedly connected to the side of the multi-pressing plate 34 facing the surface of the unloading table 1. The multi-pressing plate 34 drives the multiple pressing heads 31 to press into the placement groove 241. When abutting, the bottom surface of the placement groove 241 is pushed out and deformed by the abutting rod 12, so that the copper seat can receive greater pressure.

[0030] The working principle of this mechanism is as follows: When pressing multiple spiral spring copper seat assembly workpieces, several spiral spring workpieces are placed in the placement groove 241, and the hole in the center of the copper seat is fitted onto the limiting block 242. The pressing cylinder 33 is activated, and at the same time, the forward driving linear module 21 is activated, causing the placement plate 24 to move towards the contact rod 12 and causing the contact plate to drive the bottom surface of the placement groove 241 to deform. At this time, the driving linear module 21 is stopped, and the pressing cylinder 33 continues to drive the multiple pressing plates 34 to approach the surface of the placement plate 24, so that multiple pressing heads 31 extend into the placement groove 241. The copper base and the spiral spring are pressed together by the contact rod 12 and the pressing head 31. Under the clamping and pressing of the contact rod 12 and the pressing head 31, the copper base and the spiral spring are riveted tightly. Then the pressing cylinder 33 is driven in reverse to release the pressing effect. The linear module 21 is driven in reverse, so that the rack structure 22 drives the gear structure 11 to rotate and drives the rotating shaft 23 to rotate. This causes the placement plate 24 to rotate around the rotating shaft 23, and a high-speed airflow is introduced into the air blowing port 243, so that the spiral spring workpiece in the placement groove 241 is blown into the material collection groove 14, thus completing the riveting process of multiple spiral spring workpieces.

[0031] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
