Problems solved by technology

The disadvantage of this method is that the surface is processed twice, and the flatness is difficult to guarantee. The surface structure and the surface are processed twice. The two positioning errors are prone to occur, which is not conducive to the control of the quality of the workpiece, and it is easy to cause differences in the processing of different batches of workpieces. major issues

Embodiment 1

[0022] The clamping device for thin plate workpieces with holes in embodiment 1 is used for clamping the cam plate for load switch. In other embodiments, the clamping device can also be used for clamping other thin-plate workpieces with holes.

[0023] The supporting structure of the inner hole of the clamping device for thin plate workpieces with holes in Example 1 is an expanding mandrel, which is used for positioning the middle hole of the workpiece and preventing deformation of the middle hole. In other embodiments, the inner hole support structure can also be other structures that prevent the deformation of the middle hole of the workpiece, such as a cylindrical support block that is installed in the middle hole of the workpiece to support the middle hole of the same size as the middle hole of the workpiece.

[0024] The clamping device for thin plate workpieces with holes in embodiment 1 realizes the clamping of workpieces by fixing the groove wall of the platform groove...

Abstract

The invention provides a clamping device for a thin plate workpiece with a hole. The clamping device comprises a base, wherein a fixing platform which is used for supporting the workpiece is arranged on the base. The clamping device further comprises an inner hole supporting structure and a clamping mechanism, wherein the inner hole supporting structure is used for passing through the workpiece middle hole, and the clamping mechanism is used for clamping the workpiece on the side. The workpiece is clamped by the clamping mechanism after the workpiece middle hole is fixed by the inner hole supporting structure, and therefore the deformation of the middle hole can be effectively avoided, the deformation in the clamping process of the workpiece is reduced, then the value of whole deformation resilience, generated after machining is accomplished, of the workpiece is reduced, and the machining accuracy is guaranteed. The workpiece is firmly positioned by the clamping device, machining of the surface and the surface structure can be accomplished through one-time clamping, the error caused by repeated positioning is avoided, operation is easy and reliable, the machining efficiency is high, and the machining quality of the workpiece is guaranteed.

Description

technical field [0001] The invention relates to a clamping device for thin plate workpieces with holes. Background technique [0002] Thin-plate workpieces with large middle holes (such as cam plates for load switches) need to process the surface and surface structures (such as protrusions), such as figure 1 The load switch cam plate 5 shown has a middle hole 103, and the surface 101 and the convex 102 need to be processed. Since the workpiece is relatively thin and has a large middle hole, if the workpiece is pressed from the side, it is easy to deform, and the surface and surface structure cannot be processed in one clamping. Therefore, the existing processing method is to use the pressing plate to press half of the workpiece surface 101 from top to bottom to process the other half. After the processing is completed, the half of the processed part is pressed by the pressing plate to fix the workpiece, and the unprocessed half is processed, and the processing is alternated...
