Universal fixture device and method for machining fan-shaped workpiece combinations

Abstract

The invention relates to a universal fixture device and a method for machining fan-shaped workpiece combinations. The universal fixture device and the method have the advantages that slide grooves are formed in fixture bodies of the fixture device according to the numbers of fan-shaped workpieces, the lengths of the slide grooves are designed according to the limit sizes of the workpieces, and accordingly the fixture device is high in universality; designs of fixtures are simplified, and accordingly labor, the time and the cost can be saved; tools with different specifications do not need to be selected according to the different workpieces, accordingly, the production preparation time is short, wastage of a large quantity of time for pre-machining preparation work can be prevented, the preparation time can be shortened by one week to half a month at least as compared with the prior art, the integral machining periods can be shortened, and the machining efficiency can be improved; the fan-shaped workpieces with different specifications can be machined by the same tools and the same fixtures, and accordingly the tools and the fixtures are high in utilization rate and long in service life; the service life of the fixture device can reach 7-8 years at least, accordingly, the total input for the tools and the fixtures can be reduced, and the universal fixture device is low in cost, simple in clamping process and high in machining efficiency.

Description

technical field [0001] The invention relates to a tool and a workpiece processing method using the tool, which is suitable for the processing of sector-shaped workpieces combined in circles. Specifically, it relates to a general fixture device and method for combined processing of sector-shaped workpieces, belonging to the technical field of mechanical processing. Background technique [0002] When turning the outer arc and inner arc of the fan-shaped workpiece, or when performing electrical machining, it is often processed after the combination of circles, which can improve the processing efficiency and ensure the consistency of the machining accuracy of each fan-shaped workpiece. [0003] At present, there are many different methods for combining fan-shaped workpieces into circles, such as welding and fixture tooling. However, the welding method can only be used for steel materials, and cannot be used for aluminum materials or other non-steel materials. Due to the differe...
