Arbitrary angle expanding device for fixed angle head and use method thereof

Abstract

The invention discloses an arbitrary angle expanding device for a fixed angle head and a using method thereof.The device comprises an annular inner pressing ring, a working ring, an outer pressing ring and a fixing block, a mounting concave part is formed in the surface of one side of the fixing block, and an annular groove, a plurality of first screw holes and a plurality of second screw holes are formed in the bottom face of the mounting concave part; a disc spring is placed in the annular groove, the first screw holes are evenly distributed in the radial outer side of the annular groove, the second screw holes are evenly distributed in the radial inner side of the annular groove, a plurality of connecting through holes are formed in the outer edge of the fixing block, an annular flange is arranged on the annular face of one side of the working ring, and a positioning groove is formed in the annular flange. A plurality of third screw holes and a plurality of fourth screw holes are evenly distributed in the inner pressing ring and the outer pressing ring respectively. A fixed angle head is expanded into a universal angle head, the advantage of low cost of the fixed angle head and the advantage of any angle adjustment of the universal angle head are both achieved, the angle adjustment time is remarkably shortened, the machining efficiency is improved, and the purposes of low cost and high efficiency are achieved.

Description

technical field [0001] The invention belongs to the technical field of machining, and in particular relates to an arbitrary-angle expanding device for a fixed-angle head and a method of use thereof, so as to realize arbitrary-angle adjustment of the fixed-angle head. Background technique [0002] The angle head as a machine tool accessory can realize the expansion of machine tool functions. The existing angle head is divided into two types: universal angle head and fixed angle head. Axis fixed angle processing. Although the universal angle head can realize multi-angle processing, its mechanism is complex, expensive, and the repair rate is high; the fixed-angle head is simple in structure, low in price, and the repair rate is low, but the multi-angle processing is complicated to use. [0003] Such as figure 1 As shown, the fixed-angle head in the prior art is used in the following way: the fixed-angle head 1 is connected to the main shaft of the machine tool through the han...

AI Technical Summary

Problems solved by technology

The fixed-angle head 1 itself is fixed relative to the machine tool ram 4, and can only process workpieces in one direction. If other angle positions of the parts need to be processed, the fixed-angle head 1 needs to be removed, the stopper 3 is removed, and the position is replaced before fixing. It takes a long time to adjust, and due to the limitation of a large number of bolts on the machine tool ram 4, it is impossible to adjust at any angle
