Vertical type machine tool and high-precision circle rectifying clamp thereof

Abstract

The invention discloses a high-precision circle rectifying clamp of a vertical type machine tool. The high-precision circle rectifying clamp comprises a clamping bottom plate arranged on a tool body,at least three sliding rails, abutting plates, a support plate arranged on the surface of the clamping bottom plate, and a tray. The sliding rails are arranged on the clamping bottom plate and are evenly distributed in the circumferential direction. The abutting plates can be arranged on all the sliding rails synchronously slidably and are used for abutting against the annular-direction inner wallof a to-be-measured workpiece. The tray is arranged at the top of the support plate and is used for abutting against the top inner wall of the to-be-measured workpiece. The abutting faces of the abutting plates are arc-shaped faces used for being tightly attached to the annular-direction inner wall of the to-be-measured workpiece. The top surface of the tray is a curved face used for being tightly attached to the top inner wall of the to-be-measured workpiece. In this way, when an end socket class workpiece is clamped, the workpiece can be put upside down on the clamping bottom plate and reaches a balance position through abutting of the abutting plates and the tray to the annular inner wall and the top inner wall of the workpiece, and trimming chamfering precision and the circle rectifying effect on the workpiece are improved. The invention further discloses the vertical type machine tool, and the beneficial effects are as mentioned above.

Description

technical field [0001] The invention relates to the technical field of mechanical design, in particular to a high-precision circle calibration jig for a vertical machine tool. The present invention also relates to a vertical machine tool comprising the above-mentioned high-precision circle calibration jig. Background technique [0002] With the development of China's machinery industry, more and more machinery and equipment have been widely used. [0003] In automobile manufacturing enterprises, auto parts are one of the important production links. Auto parts (autoparts) are the various units that make up the whole car and a product that serves the car. There are many types of auto parts, which can be divided into: engine system, such as engine assembly, filter, cylinder and parts, connecting Rod assembly, crankshaft camshaft, bearing bush and connecting rod bush, valve and parts, etc.; walking system, such as front axle, rear axle, shock absorption system, suspension syst...

AI Technical Summary

Problems solved by technology

In the existing technology, it is generally processed by ordinary large-scale large-scale horizontal lathes. The equipment used is large in size and high in cost. The side clamping requires 2 to 3 people to operate. Since the parts themselves are heavy, the clamping process of the parts is prone to accidents. Tilting, which in turn leads to large trimming deviation during processing

In addition, conventional lathe processing generally uses a three-jaw chuck, the contact area between the jaws and the part is small, and the effect of tightening the circle is poor
