Device for turning and grinding outer cylindrical surfaces

Abstract

The invention relates to a device for turning and grinding outer cylindrical surfaces. The device is used for machining the outer cylindrical surfaces of outer cylindrical surface class workpieces with the central angle being smaller than 180 degrees. The device comprises a clamp body and a fixing piece, the two ends of the clamp body are each provided with a section of cylinder, and center holes are formed in the end faces of the cylinders. A clamp main body is arranged in the middle of the clamp body, workpiece locating surfaces are arranged on the clamp main body, and the fixing piece and the clamp main body are matched so that the workpieces can be located and clamped on the workpiece locating surfaces. The device for turning and grinding the outer cylindrical surfaces solves the clamping problem for machining the outer cylindrical surfaces of non-whole-cylindrical-face class workpieces on a machine tool, the workpieces can be used for one-piece blanking according to the appearances of the workpieces, the appearance sizes of the workpieces are made more appropriate, raw materials are saved, meanwhile, the machining amount and machining difficulty are reduced, two or more workpieces can be clamped to be machined at the same time, and thus the machining efficiency is improved.

Description

technical field [0001] The invention relates to a device for turning and grinding an outer cylindrical surface, in particular to a device for processing an outer cylindrical surface whose central angle is less than 180°. Background technique [0002] Since the outer cylindrical surface workpieces with a central angle of less than 180° cannot be directly clamped and added to the machine tool for machining the outer cylindrical surface, the current common method for machining the outer cylindrical surface of the outer cylindrical surface workpieces with a central angle of less than 180° is The material is cut into a large bar, first turned into a ring sleeve, and then the ring sleeve is milled and cut into multiple single pieces. However, this processing method has the following problems: 1. The ring sleeve greatly increases the size of the raw materials used, and the processing volume is large, resulting in waste of materials; 2. When the workpiece needs to be ground after ha...

[0003] In view of this, the object of the present invention is to provide a device for turning and grinding the outer cylindrical surface, so that it can directly separate the outer cylindrical surface according to the shape of the workpiece when processing the outer cylindrical surface of the outer cylindrical surface workpiece with a central angle of less than 180 °. Part blanking, positioning and clamping the workpiece, and clamping the workpiece to the machine tool for processing solves the problem that some cylindrical workpieces cannot be directly clamped on the machine tool, which is very suitable for practical use
