Description
Technical Field
[0001] This utility model relates to the field of machining fixture technology, and specifically discloses a connector punching fixture. Background Technology
[0002] Connector punching fixtures are specialized equipment and tools used in the electronics manufacturing industry for producing connector components. They are mainly used for fixing, positioning, loading and unloading, processing, testing and inspecting connector workpieces. Punching fixtures play a crucial role in the connector manufacturing process, especially in the punching process.
[0003] Currently, in connector punching, when using traditional fixtures for positioning, the workpiece is prone to shifting under impact, leading to deviations in the punching position, resulting in defective workpieces, increased material costs, and a serious impact on the production efficiency of workers. Therefore, a connector punching fixture is needed to solve this problem. Utility Model Content
[0004] This utility model proposes a connector punching fixture, which adopts a contour positioning component with a contour positioning cavity inside that matches the shape of the workpiece to achieve initial positioning. With the help of a positioning clamping device, the workpiece is dynamically locked during the punching process to prevent displacement. This solves the problem that when traditional fixtures are used for positioning, the workpiece is easily displaced under the influence of impact force, resulting in deviation of the punching position and the production of defective workpieces.
[0005] This utility model is implemented as follows: a connector punching fixture includes a base, a base column fixedly connected to the outer surface of the base, an impact device on the outer surface of the base column, a contour positioning component on the outer surface of the base, a positioning clamping device inside the contour positioning component, a workpiece positioning mold on the outer surface of the base, and a guide hole on the outer surface of the workpiece positioning mold.
[0006] As a preferred embodiment of the connector punching fixture of this utility model, the outer surface of the base post is provided with a guide groove, a guide rod is slidably connected inside the guide groove, the end of the guide rod away from the guide groove is engaged with the outer surface of the impact device, and a controller is provided on the outer surface of the base post.
[0007] As a preferred embodiment of the connector punching fixture of this utility model, the contour positioning component includes a set of mating holes and a contour positioning cavity, and a set of mating blocks are fixedly connected to the outer surface of the contour positioning cavity.
[0008] As a preferred embodiment of the connector punching fixture of this utility model, the size of the mating holes is adapted to the mating blocks, and the interior of the contour positioning cavity is fixedly connected to the outer surface of the positioning and clamping device.
[0009] As a preferred embodiment of the connector punching fixture of this utility model, the outer surface of the base is provided with an inclined waste groove, and the outer surface of the base is provided with a collection box.
[0010] As a preferred embodiment of the connector punching fixture of this utility model, a set of stabilizing blocks are fixedly connected to the outer surface of the base, and a stabilizing pad is fixedly connected to the outer surface of each stabilizing block. A set of shock-absorbing holes are provided on the outer surface of the base.
[0011] The beneficial effects of this utility model are:
[0012] 1. This connector punching fixture uses a contour positioning component with an internal contour positioning cavity that matches the workpiece shape for initial positioning. Combined with a positioning clamping device, it dynamically locks the workpiece during the punching process to prevent displacement, improving workpiece positioning accuracy to ±0.02mm. This avoids punching misalignment and increases the yield rate to over 99%. It effectively solves the problem of traditional punching fixtures where workpieces are easily displaced by impact forces during high-speed punching, leading to hole position deviations and affecting product qualification rates.
[0013] 2. This connector punching fixture, by setting guide grooves on the base column and precisely matching them with guide rods, ensures the vertical movement of the punch. At the same time, the workpiece positioning mold is provided with guide holes, which further constrains the punch path, so that there is no lateral deviation during the punching process. The punching verticality is ≤0.01mm. It is suitable for high-precision connector processing and can effectively solve the problem that traditional stamping mechanisms lack precision guidance, which easily leads to punch wobble and affects the punching quality.
