Description

Technical Field

[0001] The utility model relates to the field of fixtures, in particular to a tooling base punching fixture. Background Art

[0002] The tooling base is a basic component used to support and fix the fixture and workpiece. It has stability and durability. The main function of the tooling base is to provide a stable working platform on which the workpiece can be placed safely and stably during the processing and punching process. In order to ensure that the position of the workpiece is accurate during the punching process, a fixture is usually installed on the base to accurately position the workpiece in the required position to avoid deviation or shaking.

[0003] The existing device has the following shortcomings when in use: different sizes are required according to production needs, and punching fixtures of different specifications need to be replaced. When replacing the fixtures, the staff needs to use tools to disassemble and assemble them, which is more troublesome, increases the downtime of the equipment, and affects the processing efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a tool base punching fixture to solve the problems raised in the above background technology.

[0005] The top end of the fixing plate is fixed with a fixing block, and the fixing block is fixed with a fixing plate so as to prevent the fixing of the fixing plate from being detached from the fixing plate. The docking column installed at the bottom is aligned with the docking hole opened on the tooling base, and is inserted into the docking hole so that the limit groove opened at the bottom of the docking column fits with the limit column installed in the tooling base, and the fixture base is fixed to the left and right limits. Then the threaded rod threaded in the threaded hole is rotated, and the threaded rod moves into the tooling base, causing the connecting rod to move, driving the two sets of movable plates to move, so that the clamping block moves between the two sets of limit rings and fits against the outer wall of the docking column. The limit rings are respectively located at the upper and lower ends of the clamping block, and limit and fix the upper and lower parts of the clamp base, thereby completing the replacement of the clamp base. When replacing punching fixtures of different specifications according to different production sizes, the problem of staff needing to use tools to disassemble and assemble the mold is avoided, making the replacement of the fixture more convenient, shortening the downtime of the equipment, and improving the processing efficiency.

[0006] In a further embodiment, a fixing frame is installed on the clamp base, a screw rod is threadedly installed on the fixing frame, and a clamp is rotatably installed on one end of the screw rod. By rotating the screw rod threadedly installed on the fixing frame, the clamp is driven to move to clamp and fix the object to be punched. The punching clamp on the clamp base can be replaced with clamps of different specifications according to production needs.

[0007] In a further embodiment, the slide rod installed on the movable plate is slidably connected to the slide groove opened on the inner wall of the tooling base, and the slide rod installed on the movable plate is slidably connected to the slide groove opened on the inner wall of the tooling base, thereby ensuring the stability of the movable plate during movement.

[0008] In a further embodiment, a rubber pad is installed on the side of the splint, and a concave handle is provided on the clamp base. The rubber pad installed on the side of the splint prevents the object to be punched from being clamped and damaged, and the concave handle is provided on the clamp base to facilitate the staff to take and place the clamp base.

[0009] In a further embodiment, a sliding rod is installed in the tooling base, and the sliding rod is slidably connected to one end of the connecting rod. One end of the sliding rod installed in the tooling base is slidably connected to the connecting rod, ensuring the stability of the connecting rod when moving.

[0010] In a further embodiment, the docking poles are provided in four groups, and two groups of movable plates are mounted on the connecting rods.

[0011] Compared with the existing technology, the beneficial effect of the present invention is that when punching fixtures of different specifications need to be replaced according to different production sizes, the problem of workers needing to use tools to disassemble and assemble the mold is avoided, making the replacement of the fixture more convenient, shortening the downtime of the equipment, and improving processing efficiency.
