Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a device for fine processing of weak magnetic materials. Background Art

[0002] After the weak magnetic valve plate is assembled with the valve body through the stainless steel valve shaft, fixing screws and anti-loosening nuts, the two end faces (within 10mm from the edge) and the outer circle act as a seal. When working, it is opened and closed in an environment of 300℃.

[0003] The precision requirement of weak magnetic valve plate is relatively high, so both end faces and outer circle need to be ground. If grinding is done with a surface grinder, because the valve plate is a weak magnetic material, it cannot be adsorbed on the surface grinder, so both end faces of the part cannot be ground; if grinding is done directly with an external cylindrical grinder, the technical requirements cannot be met stably due to the high precision requirements for the flatness and parallelism of the two end faces, and the outer circle cannot be ground; if grinding is done directly with an external cylindrical grinder, because the weak magnetic valve plate is not allowed to have a center hole, and the thickness of the part is too thin, clamping cannot be achieved, so a device that can finish the weak magnetic valve plate is needed.

[0006] As a preferred technical solution of the utility model, the two ends of the clamping disk are respectively connected to the large disk end and the small disk end, and the large disk end is symmetrically provided with connecting holes corresponding to the hole positions on the weak magnetic valve plate. A connecting bolt passes through the two clamping disks and the weak magnetic valve plate, and the outer side surface of the connecting bolt is threadedly connected with a locking nut.

[0007] As a preferred technical solution of the utility model, a positioning hole is provided at the center position of the small disc end, and the positioning hole is clamped in cooperation with the center on the external cylindrical grinder.
