Abrasive belt grinding machine for inner cambered surface of small vane

Abstract

The invention discloses an abrasive belt grinding machine for an inner cambered surface of a small vane. A contact lever (9) is arranged between a first transition wheel (6) and a second transition wheel (7), a sponge grinding head (10) is mounted at the front end of the contact lever (9), a motor (2) is arranged behind a machine body (1) and mounted on an upright plate (8), and a driving wheel (3) is arranged on an output shaft of the motor (2) in a sleeving manner and connected with the first transition wheel (6), the second transition wheel (7) and the sponge grinding head (10) by an abrasive belt (4). The abrasive belt grinding machine adopts a sponge material as a grinding head, so that the diameter of the grinding head is less than 10mm, the problem that the inner cambered surface of the small vane of a compressor is difficult to grind due to the small radius of curvature is solved effectively. As a grinding belt is arranged between the sponge grinding head and the abrasive belt, and servers as an intermediate material between the sponge grinding head and the abrasive belt to replace the sponge grinding head for abrading, the service life of the sponge grinding head is prolonged greatly.

Description

technical field [0001] The invention belongs to the technical field of grinding machines, and in particular relates to a small-blade inner arc abrasive belt grinding machine. Background technique [0002] A belt grinder is a grinding machine that uses a fast-moving abrasive belt as an abrasive tool for grinding and polishing. With the rapid development of grinding machine technology, abrasive belt grinding machines have developed into high-efficiency and low-power finishing equipment. Especially in the processing of large-size plates, pipes, bars and complex curved surfaces, its advantages are particularly obvious. Abrasive belt grinding is driven by the driving wheel to move the abrasive belt, and the tensioning wheel is used to tension the abrasive belt. The back pressure is provided by the contact wheel or the support plate to generate contact pressure on the workpiece and form a cutting angle to complete the grinding process of the workpiece. .

AI Technical Summary

Problems solved by technology

[0003] Grinding the inner arc surface of small compressor blades has always been a difficult problem in grinding. Because the radius of curvature of the inner arc of this type of blade is very small (below R5), the radius of the contact wheel for abrasive belt grinding in the past is smaller than that of this type of blade. If the radius of curvature is larger or smaller, it will not be able to be ground
