Quick clamping device for sleeve-like parts machining

Abstract

The invention discloses a quick clamping device for sleeve-like parts machining. The device comprises: a step core shaft (1), a split washer (2), a spring washer (3) and a locknut (4). Since the splitwasher (2) is provided with a gap, and the maximum shapes of the spring washer (3) and the locknut (4) are smaller than the inner diameter of a sleeve part (5) to be processed, the spring washer (3)and the locknut (4) do not need to be dismounted when replacing parts, and the locknut (4) is loosened by one to two circles, and thus the sleeve part (5) to be processed is dismounted. The split washer (2) can be attached and detached from the side surface by using the gap. Through fit tolerance of the outer diameter of the step core shaft (1) and the inner diameter of the sleeve part (5) to be processed, coaxiality and quality are ensured. The device has novel design, simple implementation and low cost, and can improve the surface processing quality and processing efficiency of the sleeve-like parts and shorten product cycle.

Description

technical field [0001] The invention relates to a clamping device, in particular to a quick clamping device for machining sleeve parts. Background technique [0002] As the most commonly used structural type of mechanical parts, sleeve parts are widely used in various industries such as aviation, aerospace, national defense, and automobiles. There are usually three clamping methods when machining the outer circle of sleeve parts: one is to directly clamp the outer circle of the part with the chuck of the lathe; the second is to use the front and rear tops to withstand the two ends of the part respectively; Put the part on the stepped mandrel, clamp the stepped mandrel with the chuck, and use the back top to support the part. However, when the long diameter of the sleeve-type parts is relatively large or the wall is relatively thin, the general clamping method is likely to cause the part to be clamped and deformed or slightly slipped during processing, which cannot guarantee...
