Description

Technical Field

[0001] The utility model relates to the technical field of contact riveting processing, in particular to an adjustable tooling fixture for contact riveting processing. Background Art

[0002] Contacts are key components of electrical switches. Based on their structure and operating characteristics, they can be categorized into three types: breakable, sliding, and fixed. They require low current cutoff values, high compressive strength, and high breaking capacity. The microstructure of the contact material significantly influences its macroscopic performance. The electrical properties of the contact material, such as resistance to welding, arc erosion, and withstand voltage, are related not only to the composition of the contact material but also to the grain size of the constituent materials.

[0003] According to a stamping device for processing static contacts for disconnectors disclosed on the patent website (authorization announcement number: CN216957804U), "the utility model belongs to the field of disconnectors, specifically a stamping device for processing static contacts for disconnectors, including a driving device and a moving device. The moving device is provided at the front of the driving device; the driving device includes a counterweight, a support beam, a motor bracket, a driving motor, a V-belt, a bearing seat, a rotating shaft, a driving gear, an eccentric gear, a support shaft, a first connecting rod, a second connecting rod, a third connecting rod, a travel seat, and a punch. The driving motor drives the rotating shaft to rotate through the V-belt, so that the driving gear rotates, thereby driving the eccentric gear to rotate, causing the support column to perform a circular motion. At the same time, the first connecting rod rotates, so that the second connecting rod and the third connecting rod move, thereby moving the travel seat and the punch. The servo motor drives the ball screw to rotate, so that the moving seat drives the workbench to move, and the hydraulic cylinder drives the bottom plate to move up and down, so that the workbench can move and lift, and multiple parts can be processed at the same time, thereby improving efficiency."

[0004] Based on the above, the applicant believes that the following defects exist:

[0005] The stamping device for processing the static contacts of the isolating switch includes a driving device and a moving device. The servo motor drives the ball screw to rotate, so that the moving seat drives the workbench to move, and the hydraulic cylinder drives the base plate to move up and down, so that the workbench can be moved and raised, and multiple parts can be processed at the same time to improve efficiency. The device is not equipped with a clamping device for the contacts. When the contacts are processed, the two riveted parts of the contacts may fall off or have unnecessary displacement, which will eventually affect the contact riveting work. Utility Model Content
