Description

Technical Field

[0001] The utility model relates to the technical field of riveting pliers, in particular to a split riveting pliers. Background Art

[0002] The starter of a car engine, also known as a starter motor or starter, usually converts battery electricity into mechanical energy, and then drives the engine through a transmission mechanism. The electromagnetic switch for the starter, also called a magnetic switch, is mainly composed of an attraction coil, a holding coil, a movable iron core, a reset spring, and main and auxiliary contacts. The most common starter usually includes four current terminals. When riveting the switch terminals of the starter, an integral rivet clamp is usually used. After using the integral rivet clamp for a long time, the hardness of the rivet clamp material is low, resulting in rapid wear of the rivet working part, resulting in a short life of the rivet clamp. Therefore, some split rivet clamps have appeared in the prior art, which use a rivet block to replace the rivet working part and are connected to the rivet clamp body by bolts. When wear occurs, the rivet block can be directly replaced without affecting the service life of the rivet clamp.

[0003] However, in actual work, there are some problems with the existing split riveting pliers: on the one hand, the rivet block is connected to the rivet pliers body only by bolts. After the rivet pliers are used for a long time, the connection stability of the bolts to the rivet block is reduced, resulting in a small deviation of the two relative rivet blocks in the riveting direction, reducing the riveting accuracy of the switch terminals, resulting in poor riveting quality of some switch terminals; on the other hand, the rivet pliers need to manually open the handle repeatedly when in use, which wastes time and increases the workload of workers. Utility Model Content

[0004] In order to solve the technical problems in the prior art that after long-term use, the two relative rivet blocks of the rivet clamps are slightly offset in the rivet direction, the rivet accuracy of the switch terminals is reduced, and the riveting quality of some switch terminals is poor. When the rivet clamps are used, the handles are repeatedly opened manually, which wastes time and increases the work intensity of workers. The utility model provides the following technical solutions.

[0005] The utility model discloses a split riveting pliers, comprising a first handle fixedly connected to a first riveting head and a second handle hinged to a second riveting head, the first riveting head and the second riveting head having the same structure and being arranged opposite to each other, one end of the first riveting head being hinged to the second riveting head, the first handle being hinged to the second handle through a pressure regulating component, a positioning groove being provided on a side opposite to the first riveting head and the second riveting head, at least one positioning hole being provided on an upper part of the positioning groove, a fixing screw hole being provided in a horizontal direction of the first riveting head penetrating the positioning groove, the first riveting head and the second riveting head being respectively connected to a first riveting block provided with a first riveting portion and a second riveting block provided with a second riveting portion which are arranged opposite to each other, the first riveting block comprising a block body matching the shape of the positioning groove and a positioning protrusion matching the positioning hole, the first riveting block also comprising a penetrating screw hole fixed by a first bolt matching the fixing screw hole, so as to stably connect the first riveting block to the first riveting head.

[0006] As a further technical solution, the first rivet head further includes overlapping portions located on both sides of the opening of the positioning groove, and the block further includes a limiting portion extending in the direction of the overlapping portions.

[0007] As a further technical solution, an elastic component is connected between the first handle and the second handle.

[0008] As a further technical solution, the elastic component includes a spring fixedly connected to the first handle and the second handle.

[0009] As a further technical solution, the elastic component includes a telescopic sleeve fixed to the lower part of the first handle and a spring located at the outer periphery of the telescopic sleeve, and the other end of the telescopic sleeve is hinged to the second handle through a hinge.

[0010] As a further technical solution, the second rivet clamp block is connected to the second rivet clamp head via a second bolt.

[0011] The utility model has the beneficial effects that the first rivet head and the second rivet head arranged relatively to each other are respectively connected with the first rivet block and the second rivet block, the first rivet head and the first rivet block cooperate with each other for positioning, the first rivet block includes a block body matching the shape of the positioning groove and a positioning protrusion matching the positioning hole, the first rivet block also includes a through screw hole fixed by a first bolt matching the fixing screw hole, the first rivet block and the first rivet head can be positioned and connected from multiple directions, the connection stability of the first rivet block and the first rivet head is higher, after long-term use, the two relative rivet blocks will not be offset in the rivet direction, and the rivet accuracy of the switch terminal is improved. An elastic component is arranged between the first handle and the second handle, and the elastic component is provided with a telescopic sleeve and a spring. After the rivet is completed, the spring can automatically pop the first handle and the second handle apart, and the rivet clamp does not need to be opened manually repeatedly when in use, which reduces the work intensity and improves the work efficiency.
