Moving contact riveting tool

Abstract

The utility model discloses a moving contact riveting tool which comprises a working table, a supporting frame is fixedly installed on one side of the top end of the working table, an air cylinder is installed at the top end of the supporting frame, a lifting plate is fixedly connected to the bottom of the air cylinder, and a punching head is arranged in the middle of the bottom end of the lifting plate. A guide rod is fixedly mounted at the corner of the top end of the lifting plate; the combined use of a rubber pad, a movable rod and a first spring can facilitate the subsequent simple buffer protection of a moving contact subjected to stamping treatment, thereby preventing the damage of the moving contact caused by the overlarge stamping force of a stamping head, affecting the subsequent normal use of the moving contact, causing unnecessary material loss, and reducing the production cost. When the rubber pad is in contact with the moving contact, the movable rod is pushed longitudinally, then the movable rod moves longitudinally and drives the first springs to deform to generate reverse acting force, and the purpose of buffering protection can be achieved by combining the reverse acting force generated by deformation of the multiple first springs.

Description

Technical Field

[0001] The utility model relates to the field of riveting tooling for moving contacts, in particular to a riveting tooling for moving contacts. Background Art

[0002] Moving contacts refer to contacts that move during operation. They play a key role in high-voltage switches. For example, the two arms installed on the trolley that connect the switch to the system are moving contacts, while the fixed ones are used in conjunction with the static contacts. Riveting tooling is required when processing the moving contacts.

[0003] However, the current riveting tooling for moving contacts uses the work of a cylinder or a hydraulic cylinder to realize the longitudinal movement of the pressing head, and then uses the longitudinally moving pressing head to rivet the moving contact. This direct stamping riveting method may cause damage to the moving contact due to excessive pressure during the riveting process, thereby affecting the subsequent normal processing of the moving contact, causing unnecessary material loss, and is not practical. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the utility model provides a moving contact riveting tool, which can solve the problem that the current moving contact riveting tool, when riveting the moving contact, realizes the longitudinal movement of the pressure head through the work of a cylinder or a hydraulic cylinder, and then uses the longitudinally moving pressure head to rivet the moving contact. However, such direct stamping riveting method may cause damage to the moving contact due to excessive pressure during the riveting process, thereby affecting the subsequent normal processing of the moving contact, causing unnecessary material loss and poor practicality. Technical problems.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a moving contact riveting tool, comprising a workbench, a support frame is fixedly installed on one side of the top of the workbench, and a cylinder is installed on the top of the support frame, a lifting plate is fixedly connected to the bottom of the cylinder, and a punching head is arranged in the middle of the bottom end of the lifting plate, a guide rod is fixedly installed at the top corner of the lifting plate, a rubber pad is distributed on one side of the punching head, and a movable rod is fixedly installed on the top of the rubber pad, a first spring is sleeved on the outer side of the bottom of the movable rod, and a locking structure is opened on the upper surface of the workbench.

[0006] As a preferred technical solution of the utility model, the locking structure includes a groove, a slot, a retraction groove and a slide rail, the groove is opened on the upper surface of the workbench, and one side of the groove is connected to the slot, one end of the groove is connected to the retraction groove, and the top of the retraction groove is connected to the slide rail.

[0007] As a preferred technical solution of the utility model, the inner cavity of the groove is provided with a socket, and a plug plate is fixedly installed on one side of the socket, a support platform is provided on the top of the socket, and a positioning hole is opened on the surface of the socket.

[0008] As a preferred technical solution of the utility model, the inner cavity of the retraction groove is fixedly connected to a second spring, and the other end of the second spring is fixedly connected to a positioning rod, and a shift block is provided on the top of one end of the positioning rod.

[0009] As a preferred technical solution of the utility model, the guide rods are equidistantly distributed along the center point of the lifting plate, and the lifting plate is slidably connected to the support frame through the guide rods.

[0010] As a preferred technical solution of the utility model, the positioning rod is slidably connected to the workbench through the second spring, and the positioning rod is symmetrically distributed along the vertical center line of the workbench.

[0011] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0012] 1. By using the combination of the set rubber pad, the movable rod and the first spring, it is convenient to play a simple buffering and protection purpose for the subsequent stamping process of the moving contact, so as to prevent the punching head from punching too hard, causing damage to the moving contact, thereby affecting the normal use of the subsequent moving contact and causing unnecessary material loss. When the rubber pad contacts the moving contact, it will push the movable rod longitudinally, and then the movable rod will move longitudinally, and drive the first spring to deform and generate a reverse force. The reverse force generated by the deformation of multiple first springs can achieve the purpose of buffering and protection;

[0013] 2. By using the positioning rod, the second spring and the shift block in combination, the subsequent quick connection between the workbench and the socket can be facilitated, and the subsequent replacement is also convenient, with higher flexibility. The reverse force generated by the deformation of the second spring will push the positioning rod laterally, and then the positioning rod will move laterally. When one end of the positioning rod is input into the positioning hole opened on the inner side of the socket, the socket and the workbench can be quickly connected. It is not only easy to disassemble, but also convenient to replace. BRIEF DESCRIPTION OF THE DRAWINGS
