Jig and lathe with same

Abstract

The invention discloses a clamp and a lathe with the same used for reducing the processing cost of sleeve parts. The clamp provided by the invention comprises a clamp lower plate, a clamp upper plate, a profiling, a profiling propping member, at least two elastic tightening members and a part fixing device, wherein the clamp lower plate is fixed above a sliding box of the lathe, the clamp upper plate is placed above the clamp lower plate in a folding way and can rotate corresponding to the clamp lower plate, and the profiling is fixed on a guide rail of the lathe and is provided with a profiling molded surface matched with the shape of an inner molded surface of the sleeve part formed; the profiling propping member is fixed on a first structural member at one side of the clamp upper plate and is propped against the profiling molded surface of the profiling, the two expansion ends of each elastic tightening member are respectively propped against a side board of the sliding box of the lathe and a second structural member at another side of the clamp upper plate, and the sleeve part is fixed above the clamp upper plate by the part fixing device.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a fixture and a lathe having the same. Background technique [0002] At present, sleeve parts with a relatively regular inner surface shape can be processed by a boring tool, while sleeve parts with a more complex inner surface shape need to be processed by a CNC lathe. Boring tools need to be made separately for the profile, and the expensive tool costs and CNC lathe processing fees will undoubtedly greatly increase the processing costs of this type of parts. Contents of the invention [0003] Embodiments of the present invention provide a fixture and a lathe having the same, which are used to reduce the processing cost of sleeve-like parts. [0004] The clamps provided by the embodiments of the present invention include: [0005] The lower plate of the fixture is fixed on the lathe slide box; [0006] The upper plate of the fixture is stacked on the lower pla...
