Positioning clamp for outer cover of taper clutch

Abstract

The invention discloses a positioning clamp for an outer cover of a taper clutch and relates to a clamp. The positioning clamp for the outer cover of the taper clutch comprises a fixing part, a clamping part and a driving part. The fixing part is in an L shape. The clamping part and the driving part are arranged on the two sides of the fixing part respectively. The driving part comprises a fixing sleeve, a driving rod and a handle. The fixing sleeve is fixed to the left side of a clamping installation block and is provided with an inner thread. An outer thread is arranged at one end of the driving rod, and a frustum with the taper of 45 degrees is arranged at the other end of the driving rod. The outer thread of the driving rod is matched with the inner thread of the fixing part. The clamping part comprises clamping blocks and a clamping block positioning seat. The three clamping blocks are in a long bar square block shape. The two ends of each clamping block are semicircular, and wedge faces with the inclination of 45 degrees are arranged at the two ends of each clamping block. The clamping blocks are installed on the clamping block positioning seat in a sliding manner so that the clamp can conduct positioning and clamping from the inner circumference of the outer cover of the clutch, and the outer circumference of the outer cover of the taper clutch is ground at a time.

Description

technical field [0001] The invention relates to a clamp, in particular to a positioning clamp for a tapered clutch cover. Background technique [0002] There is an outer cover of a taper clutch, which is cylindrical in shape, closed at one end, and cast. Due to assembly requirements, the outer peripheral surface needs to be polished. The existing grinding method is to clamp the outer cover of the taper clutch with a chuck-type fixture. The outer circumference of one end, and then use the eccentric grinding head to grind the unclamped end; then grind the previously unpolished end at the other end clamping the tight taper clutch cover. This method requires two positioning, This makes the machining process tedious and time-consuming; and in the two times of grinding butt joint, it is easy to form butt joint convex marks on the outer periphery of the taper clutch cover. Contents of the invention [0003] The present invention intends to provide a positioning fixture for a tap...
