[0002] The hook spring of the present invention is a special structural member, and its structure is as follows Figure 1 As shown in the figure, a C-shaped structural component is formed by folding a steel strip in half and then stamping it. After stamping, this C-shaped structural component needs further processing, especially grinding the tail end to ensure the product's size and smoothness. The traditional processing method is to have workers use a handheld angle grinder to repeatedly grind the end of the workpiece with the end face of the grinding wheel on the angle grinder. This method is not only inefficient but also causes severe wear on the grinding wheel. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a device for processing a hook spring workpiece, wherein the device can quickly process the tail end of the hook spring workpiece.

[0004] In order to solve the above technical problems, the technical solution of the present invention is: a device for processing a hook spring workpiece, wherein the hook spring is a C-shaped structural member formed by folding a steel strip in half and then stamping it, and the device includes a base plate and a workpiece positioning seat, a fixing frame and a support frame installed on the base plate, the workpiece positioning seat is used to accommodate and fix the hook spring workpiece, the fixing frame is fixedly connected to the base plate or formed as one piece, and the support frame is movably connected to the fixing frame through a rotating shaft, and an angle grinder is fixedly installed on the support frame. By manually pulling the support frame to make it move around the rotating shaft relative to the rotating shaft, the angle grinder can be driven to move, so that the angle grinder gradually approaches the workpiece positioning seat and then uses the periphery of the grinding wheel to perform cutting-type grinding on the tail end of the hook spring workpiece.

[0005] In the above technical solution, since the workpiece positioning seat can accommodate and fix the hook spring workpiece, the support frame can drive the angle grinder to rotate around the axis relative to the base plate, and the angle grinder works by using the periphery of the grinding wheel to perform cutting and grinding on the tail end of the hook spring workpiece. In this way, the tail end of the hook spring workpiece can be processed quickly and accurately, and the end face after processing is very smooth, which greatly improves the processing efficiency and processing accuracy, and reduces the wear on the grinding wheel.

[0006] Furthermore, a clamping mechanism for fixing the workpiece locating seat is also installed on the base plate, so as to better accommodate workpiece locating seats of different specifications.

[0007] In one embodiment, the clamping mechanism includes a fixed block, a movable block, a screw hole seat and a screw rod. The fixed block and the screw hole seat are both mounted on the base plate by bolts. One end of the screw rod passes through the screw hole seat and is movably connected to the movable block. The lower part of the movable block is embedded in the slide groove or strip hole of the base plate. By turning the screw rod, the movable block can be driven to move along the slide groove or strip hole. The workpiece positioning seat is located between the fixed block and the movable block.

[0008] Furthermore, in order to enable the support frame to automatically return to its original position after the user lets go, a tension spring is provided between the support frame and the base plate.

[0009] Furthermore, a limiting structure is provided on the support frame or the base plate to limit the maximum rotation angle of the support frame.

[0010] Furthermore, in order to facilitate the rotation of the support frame, a handle is provided on the support frame. BRIEF DESCRIPTION OF THE DRAWINGS
