A floating self-centering quick-change gear-shaping fixture

Abstract

The invention provides a floating self-centering quick-change gear-shaping fixture, which comprises a fixture body fixedly arranged on a machine tool worktable, the fixture body clamps and inserts a workpiece; Sleeve connecting ring, expanding sleeve, adjusting assembly and thimble assembly; the base is provided with a through hole, the connecting plate is arranged at the bottom of the base, and is connected with the base through the sleeve expansion rod, and the thimble assembly is placed in the through hole of the base , and is fixedly arranged near the bottom of the base for high-precision radial positioning of the workpiece in the base; the expansion sleeve connecting ring is sleeved in the inner hole of the base, and the bottom end is matched with the top end of the expansion sleeve pull rod. , the bottom of the expanding sleeve is embedded in the inner hole of the base, the bottom end is set on the top of the connecting ring of the expanding sleeve through threaded connection, and the adjusting component is sleeved on the expanding sleeve, which is used to adjust the verticality of the expanding sleeve and the machine tool table. , you can quickly change production without disassembling other internal gear tooling parts.

Description

technical field [0001] The invention relates to the technical field of mechanical clamping, in particular to a floating self-centering quick-change gear-shaping clamp. Background technique [0002] At present, the domestic internal gear clamps are all disassembled as a whole. When changing production, the whole set of clamps needs to be removed from the machine tool and transported to the ground, and then the new clamps are transported from the ground to the machine tool table and fixed, while the weight of the clamps It is about 90kg, which is basically impossible to carry by manpower. It can only be carried with the aid of lifting auxiliary equipment such as aircraft, which will inevitably cause the operator's burden and complaints. In addition, the inserting tooth fixture is generally assembled directly with the taper surface of the expanding sleeve. The machining accuracy is directly affected by the manufacturing accuracy of the fixture, and the frequency of unqualified ...

AI Technical Summary

Problems solved by technology

[0004] In view of the problems in the prior art that all tooling parts need to be replaced during production change, the tooling is heavy, difficult to disassemble, and prone to poor precision after disassembly, the present invention provides a floating self-centering quick-change gear shaper fixture, which can be used during processing Realize the floating self-centering of the expansion sleeve, reduce the influence of the fixture's own precision on the machining accuracy; only the top mechanism and the expansion sleeve can be taken out and replaced during the production change and debugging, and the rapid production change can be realized without disassembling other inserting gear tooling parts
