Grinding clamp and clamping method suitable for thin-wall long spacer bush

Abstract

The invention discloses a grinding clamp suitable for a thin-wall long spacer bush. The clamp comprises a moving disc base and a top disc base which are oppositely arranged on the left side and the right side, adjusting round nuts are connected to the moving disc base and the top disc base through threads, transition cone caps with the outer surfaces as the outer conical faces are detachably connected to the right end face of the moving disc base and the left end face of the top disc base, section diameters of the outer conical faces of the transition cone caps are sequentially increased in amanner of extending from the mounting face, the cone faces of the transition cone caps are sleeved with elastic cone sleeves matched with the faces, the corresponding ends of the two elastic cone sleeves are jointly sleeved with the thin-wall long spacer bush, and the other ends of the elastic cone sleeves are located between the adjusting round nuts and the thin-wall long spacer bush. According to the grinding clamp suitable for the thin-wall long spacer bush, deforming caused by clamping in the grinding process of the thin-wall long spacer bush can be effectively reduced. The invention further discloses a grinding clamping method suitable for the thin-wall long spacer bush

Description

technical field [0001] The invention belongs to the technical field of mechanical processing equipment, and relates to a grinding fixture suitable for thin-walled long spacers. The invention also relates to a method for clamping thin-walled long spacers by using the above-mentioned grinding fixture. Background technique [0002] Thin-wall long spacers are relatively common parts in winch products, which are difficult to process and easy to deform. Due to the characteristics of its own structure, such as thin wall, long long diameter, easy deformation, both inner and outer circles need to be processed, and the roughness is Ra0.8, affected by cutting force and clamping force during conventional processing, it is easy to produce Deformation will affect the dimensional accuracy and shape accuracy of the parts, and the quality of the product cannot be guaranteed, so special fixtures are required to process it. Contents of the invention [0003] The object of the present invent...
