[0014] In order to make the purpose, technical scheme and advantages of the utility model more clear and explicit, the utility model is described in detail below by combining with the drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not limited to the utility model.

[0015] In the description of the utility model, it should be understood that the orientation or position relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0016] As Figure 2As shown, a preferred embodiment of this utility model is: a device for processing hook spring workpieces, wherein the hook spring is a C-shaped structural part formed by stamping a steel strip after folding it in half. The device includes a base plate 1 and a workpiece positioning seat 2 and a support frame 3 mounted on the base plate 1. The workpiece positioning seat 2 is used to accommodate and fix the hook spring workpiece. The support frame 3 is movably connected to the base plate 1 through a rotating shaft. An angle grinder 4 is fixedly mounted on the support frame 3. By manually turning the support frame 3 to make it rotate around the shaft, the angle grinder 4 can be moved, so that the angle grinder 4 gradually approaches the workpiece positioning seat 2 and then the circumference of the grinding wheel 5 is used to cut and grind the tail end of the hook spring workpiece.

[0017] In this embodiment, a clamping mechanism for fixing the workpiece positioning seat 2 is also installed on the base plate 1, which facilitates the better positioning of workpieces 2 of different specifications; in order to enable the support frame 3 to automatically return to its original position after being released, a tension spring is provided between the support frame 3 and the base plate 1; in order to facilitate the rotation of the support frame 3, a handle is provided on the support frame 3, and a limiting structure is provided on the support frame 3 or the base plate 1 to limit the maximum rotation angle of the support frame 3.

[0018] like Figure 2 As shown, the clamping mechanism includes a fixed block 6, a movable block 7, a screw hole seat 8, and a screw 9. The fixed block 6 and the screw hole seat 8 are both mounted on the base plate 1 by bolts. One end of the screw 9 passes through the screw hole seat 8 and is movably connected to the movable block 7. The lower part of the movable block 7 is embedded in the groove or slot of the base plate 1. Tightening the screw 9 will drive the movable block 7 to move along the groove or slot. The workpiece positioning seat 2 is located between the fixed block 6 and the movable block 7.

[0019] In this embodiment, since the workpiece positioning seat 2 can accommodate and fix the hook spring workpiece, the support frame 3 can drive the angle grinder 4 to rotate around the axis relative to the base plate 1, and the angle grinder 4 works by using the periphery of the grinding wheel 5 to cut and grind the tail end of the hook spring workpiece, so that the tail end of the hook spring workpiece can be processed quickly and accurately, and the processed end surface is very smooth, thereby greatly improving the processing efficiency and processing accuracy, and reducing the wear of the grinding wheel 5.
