Clamp convenient to mount and dismount and used for conical surface turning of combined gear

Abstract

The invention discloses a clamp convenient to mount and dismount and used for conical surface turning of a combined gear. The clamp comprises a mandrel and a clamp body. The mandrel is of an externaltaper hollow shaft structure, and the clamp body is connected coaxially connected with the large end of the mandrel. A gasket is fixedly connected to the outer end surface of the clamp body. Fixing blocks are fixedly connected to the end, close to the mandrel, of the clamp body and symmetric with respect to the axis of the clamp body. Fixing grooves are formed in the positions, corresponding to the two fixing blocks, of the end, close to the clamp body, of the mandrel correspondingly. The ends, away from the clamp body, of the fixing blocks are inserted into the corresponding fixing grooves. Positioning grooves are formed in the positions, close to the groove bottoms of the fixing grooves, of the upper ends of the fixing blocks correspondingly. The groove bottoms of the positioning groovesare fixedly connected with springs correspondingly. The other ends of the springs are fixedly connected with positioning blocks correspondingly. Positioning holes are formed in the positions, corresponding to the positioning blocks, of the groove walls of the fixing grooves correspondingly. The ends, away from the springs, of the positioning blocks penetrate through groove openings of the positioning grooves and extend into the positioning holes correspondingly. By means of the clamp provided by the invention, the clamp body is mounted and dismounted precisely and conveniently.

Description

technical field [0001] The invention relates to the technical field of turning fixtures, in particular to a fixture that is convenient for loading and unloading and combined with gear bevel turning. Background technique [0002] Combining gears are helical spur gears used for torque transmission and speed change in automobile transmissions, and their manufacturing quality directly affects the balance of automobile transmission and gear shifting. The gear has a disc-shaped structure, one end of the gear axis is a tapered shaft, and the through hole in the middle is not only the design reference of the tapered shaft, but also the positioning reference. When machining combined gears, only the inner hole and one end face can be processed under one clamping condition, and the taper shaft at the other end needs to be repositioned for reprocessing. Due to the taper fit between the bevel shaft of the combined gear and the adjacent parts, the concentricity between the taper shaft an...
