[0001] The utility model relates to a kind of clamping devices for vertical lathe processing non-magnetic ring thin plate class parts, belong to mechanical technical field. BACKGROUND

[0002] Non-magnetic thin plate class parts are relatively difficult to process in the entire mechanical processing industry, as its thickness size is small, and deformation is easy to occur when clamping, affecting the shape and dimensional error of the part. In the case of processing on the upper surface of the part, clamping cannot be performed by pressing from below. In addition, due to the non-magnetic properties of the part and the turning processing method, the part cannot be processed by using conventional electromagnetic chuck and vacuum chuck. Therefore, clamping force cannot be applied in the vertical direction of the part, and deformation caused by clamping force cannot be offset during turning, which may cause vibration during clamping, affecting the quality of the processed surface and making it difficult to process qualified parts. SUMMARY

[0003] To overcome the shortcomings of the prior art, the utility model provides a clamping device for vertical lathe processing non-magnetic ring thin plate class parts, which can clamp non-magnetic ring thin plate parts during turning, inhibit deformation caused by excessive clamping force and cutting vibration during processing, and ensure processing accuracy.

[0004] The utility model discloses the technical scheme adopted to solve its technical problems: a clamping device for vertical lathe processing non-magnetic ring thin plate class parts, comprising an electromagnetic chuck, a clamping jaw, an inner support assembly, an equal-height pad, and a fan-shaped clamping plate. The electromagnetic chuck is installed at the center of the top of the workbench through a plurality of circumferential fastening screws and T-shaped blocks. The inner support assembly is fixed at the center of the top of the electromagnetic chuck.

[0005] The inner support assembly comprises a side top block, a side top screw, and a tire plate. The tire plate is a circular plate body, which is fixed at the center of the top of the electromagnetic chuck through screws and T-shaped blocks. There are eight side top blocks, which are evenly spaced and fixed at the edge of the top of the tire plate in the circumferential direction. A horizontal side top screw is installed on each side top block.

[0006] A plurality of equally spaced equal-height pads are fixed to the top of the electromagnetic chuck in the circumferential direction on the outside of the tire plate. Four equally spaced clamping jaws are installed on the workbench in the circumferential direction on the outside of the electromagnetic chuck. Four fan-shaped clamping plates are placed on the equal-height pads on the inside of each clamping jaw in the circumferential direction. One side of each fan-shaped clamping plate is in contact with the corresponding clamping jaw.

[0007] Further, the ends of the side top screws are directed towards the center of the tire plate.

[0008] Further, the arcs of the fan-shaped clamping plates are directed towards the center of the tire plate.

[0009] The beneficial effects of this utility model are: This utility model can effectively reduce the plastic deformation of non-magnetic disc-shaped parts under the action of clamping, provide a stable clamping force, ensure that there is no gap between the part and the clamp under the action of no vertical clamping force, improve the turning condition, prevent turning vibration marks during cutting, ensure the dimensional tolerance and shape tolerance of the part, and improve the part qualification rate.
