Embodiment Construction

[0014] Such as Figures 1 to 3 As shown, an eccentric sleeve grinding fixture for a CNC spiral bevel gear milling machine of the present invention includes a process surface 3 and a clamp body 1, the clamp body 1 is a cone, and the taper of the clamp body 1 is 0.03 mm. The clamp body 1 runs through the process surface 3 and is perpendicular to the process surface 3. The two end faces of the clamp body 1 are respectively provided with a thimble hole 4, and the thimble hole 4 is 1 away from the clamp body 1. The center of the end surface is 0.5 mm, and the process surface 3 can be a large semicircular surface or a square surface.

[0015] The working process of this example: Use 40Cr round steel turning eccentric sleeve grinding jig (including the center hole at both ends) to grind the φ30 surface after quenching and tempering, and then mill the original center hole to offset 0.5 after aligning the V-shaped jig of the boring machine Then process the offset thimble hole 4, and p...

Abstract

The invention provides a grinding clamp for an eccentric bushing of a numerical control curve-tooth bevel gear milling machine. The grinding clamp comprises a process face and a clamp body, the clamp body is a cone, the clamp body penetrates through the process face and is perpendicular to the process face, the two end faces of the clamp face are correspondingly and respectively provided with a centre hole, the distance between the centre holes and the centers of the end faces of the clamp body is 0.5 mm, the taper of the clamp body is 0.03 mm, and the process face can be a large semicircular face or a square face. The grinding clamp has the advantages that the grinding precision of the eccentric bushing is improved, the mounting size of the eccentric bushing is kept consistent well, machining time is reduced, the assembling period is shortened, and a machine tool is assembled more conveniently; the structure is simple, maintenance is convenient, machining cost is low, production efficiency is high, performance is stable, mounting is convenient, and clamping and machining are convenient.

Description

technical field [0001] The invention belongs to the field of machine tool manufacturing, and in particular relates to an eccentric sleeve grinding fixture for a numerically controlled spiral bevel gear milling machine. Background technique [0002] In the existing technology, when grinding the eccentric sleeve of the CNC spiral bevel gear milling machine, a four-jaw chuck is generally used to adjust the eccentric amount of the eccentric sleeve on the internal grinding machine, and then it is ground and formed after clamping. Stability, easy damage, poor assembly accuracy and other technical problems. Contents of the invention [0003] The problem to be solved by the present invention is to provide an eccentric sleeve grinding fixture for CNC spiral bevel gear milling machine with simple structure and convenient use, which is especially suitable for grinding eccentric sleeve of CNC spiral bevel gear milling machine. [0004] In order to solve the above-mentioned technical ...
