Problems solved by technology

[0002] The inner hole of the bowl gear with small tapered hole is a tapered hole and the size is small. The shape of the workpiece is bowl-shaped. When grinding the teeth, the tapered hole is used for positioning and clamping. Because the tapered hole is too small, the mandrel is too thin, and the rigidity of the fixture is insufficient, which affects the processing. cutting efficiency and product quality

Abstract

The invention discloses a fixture for grinding small-taper-bore bowl-shaped gears in order to solve the problem of difficult processing. The fixture consists of a mandrel (1), a taper sleeve (3), a spring (4), a press cover (5) and a nut (6), wherein, a big end of a taper bore of a workpiece (2) is downwards sheathed on the mandrel (1); the taper sleeve (3) is inserted into the bore of the workpiece (2) and then sheathed with the spring (4) and the press cover (5); and the nut (6) is tightened to keep the workpiece (2) in an elastically compressed state so that a machine tool can grind gears. The small-taper-bore bowl-shaped gear grinding fixture has the beneficial effects of simple structure, convenient operation, high machining precision and high efficiency.

Description

technical field [0001] The invention relates to a jig for machining, in particular to a bowl-shaped gear grinding jig with a small tapered hole. Background technique [0002] The inner hole of the bowl gear with small tapered hole is a tapered hole and the size is small. The shape of the workpiece is bowl-shaped. When grinding the teeth, the tapered hole is used for positioning and clamping. Because the tapered hole is too small, the mandrel is too thin, and the rigidity of the fixture is insufficient, which affects the processing. cutting efficiency and product quality. Contents of the invention [0003] The invention discloses a bowl-shaped gear grinding jig with a small tapered hole to solve the above-mentioned existing technical problems and improve processing efficiency and processing quality. [0004] The present invention small taper hole bowl type gear grinding fixture is made of mandrel (1), taper sleeve (3), spring (4), gland (5) and nut (6) five parts; Wherein ...
