[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] A moving contact riveting machine, such as Figure 1 As shown, the riveting machine includes a base 1, a riveting seat 2 is fixedly installed on the base 1, a material transfer component 3 is provided on the base 1 and located at one end of the riveting seat 2, and a material feeding component 4 is provided on one side of the material transfer component 3.

[0031] like Figures 2-4 As shown, a riveting machine 11 is fixedly installed on the base 1. A drive assembly is installed on the riveting machine 11. A riveting head 12 is installed at the output end of the drive assembly. The lower end of the riveting head 12 contacts the contact element. The contact element is generally a silver rod or a copper rod. The contact element is riveted into the contact hole of the moving contact to form a moving contact silver point or copper point.

[0032] In this embodiment, the drive assembly includes an electric cylinder and a hydraulic cylinder, and the riveting head is installed at the output end of the cylinder or the hydraulic cylinder.

[0033] A carrier 13 is fixedly installed on the base 1, and a cylinder 14 is fixedly installed on the carrier 13. The output end of the cylinder 14 is set along the length of the carrier 13, and the output end of the cylinder 14 is fixedly connected to the material transfer component 3.

[0034] A material collection trough 5 is fixedly provided below the riveting base 2 to collect the moving contacts and fallen contact components after riveting.

[0035] The rivet base 2 is provided with an assembly surface 21. The assembly surface 21 and the guide plane of the carrier 13 are horizontally arranged and the connection is smoothly transitioned. A positioning hole 22 is provided on the assembly surface 21. A protrusion 23 is fixed in the positioning hole 22. The contact element moves into the positioning hole 22 with the material transfer component 3 and is supported by the protrusion 23. The edge of the positioning hole 22 has a chamfered structure.

[0036] A material clamping groove 31 is provided on one side of the material transfer component 3. The material clamping groove 31 fixes the contact element to move the contact element. A feeding guide rod 41 is fixedly connected to one side of the carrier 13. The feeding guide rod 41 is fixed above the feeding component 4 and guides and conveys the contact element. The feeding guide rod 41 is connected to the discharge port of the vibrating feeding plate. The vibrating feeding plate is fixed on the machine base 1 and contains the contact element.

[0037] The feeding guide rod 41 is connected to the clamping groove 31, which feeds the contact element into the clamping groove 31. The cylinder 14 pushes the transfer part 3 to move horizontally towards the positioning hole 22, and moves smoothly along the assembly surface 21 until it enters the positioning hole 22 and is located above the protrusion 23. Then, the cylinder 14 presses the contact element to form a flat contact structure at the upper end of the contact element. If it is necessary to directly assemble the moving contact, the processing personnel manually place the moving contact on the contact element and then rivet the contact element, and the contact is formed on the moving contact.

[0038] Example 2

[0039] Based on embodiment 1, a spring is fixedly provided below the protrusion 23. The spring is installed on the riveting seat 2. The protrusion 23 is located in the middle of the positioning hole 22 and its diameter is smaller than that of the positioning hole 22. When the contact element is located in the positioning hole 22, the contact element is supported by the protrusion 23. Then, during the stamping and riveting, the bottom end of the contact element contacts the bottom of the positioning hole 22. After the riveting is completed, the spring returns to its original position and lifts the protrusion 23 to prevent the contact from getting stuck in the positioning hole 22. At this time, it is convenient for the material transfer component 3 to push the contact forward into the receiving groove 5.
