Abstract

The invention discloses a bevel gear clamping fixture. The mounting angle of a bevel gear can be adjusted, so that bevel teeth can be conveniently cut on electric spark wire cutting equipment. The fixture mainly comprises two pieces of L-shaped iron, one piece of the L-shaped iron is used for fixing the fixture on a workbench and is connected and fastened through bolts and nuts, a round hole and a fan-shaped round groove are formed in a vertical plane, the round hole is used for fixing the position of the L-shaped iron block for clamping a gear, and the fan-shaped groove is used for connecting and adjusting the clamping angle of the bevel gear. A round hole is formed in the other L-shaped iron and used for being connected with the position where the bevel gear is fastened, a rectangular gasket is additionally arranged at the connecting position, and clamping stability is guaranteed.

Description

technical field [0001] The proposal of the present invention is a jig that clamps a helical gear and can adjust the angle, and the helical gear can be clamped and cut on a wire cutting device by using the jig. Background technique [0002] Helical gears are commonly used and important workpieces in machine tools, automobiles, ships and other equipment. During use, gears need to withstand repeated shocks and vibrations, so to ensure performance, they need to have sufficient load-bearing capacity and strength. In order to measure the performance of the gear, it is cut into two parts along the tooth shape by wire cutting, and the section is professionally inspected to determine whether the gear meets the requirements. However, during the cutting process, since the teeth of the helical gear and the axis have a certain angle, it is a difficult problem to clamp the gear. In order to solve this problem, the present invention has developed and designed a set of fixtures, through w...
