Device for manufacturing full-automatic soft fixed abrasive particle air pressure grinding wheel

Abstract

The invention discloses a device for manufacturing a full-automatic soft fixed abrasive particle air pressure grinding wheel. The device comprises an abrasive particle solidifying platform for arranging an air pressure grinding wheel bracket and is supported by a four-corner bracket; rollers are arranged in the middle of the platform; the rollers form a rolling mechanism through an annular rubber belt, and the rolling mechanism is controlled by a servo motor to rotate; brackets are arranged on the left and right sides of the platform; guide rails are arranged on the inner sides of the brackets; a connecting rod is connected between the guide rails on two sides; the up-and-down movement of the connecting rod in the guide rails is driven by a second servo motor; a transverse guide rail is arranged on the connecting rod; a gluing device and an abrasive blasting device are both arranged on a semicircular guide rail of a connecting rack; a fourth servo motor drives the gluing device and the abrasive blasting device to move on the semicircular guide rail; the connecting rack is arranged on the transverse guide rail; a third servo motor drives the connecting rack to transversely move; the gluing device comprises a first solenoid valve and a hydraulic element; and the abrasive blasting device comprises a second solenoid valve and a pneumatic element.

Description

technical field [0001] The invention relates to the field of precision machining of soft-consolidated abrasive grain pneumatic grinding wheels. Background technique [0002] The soft-consolidated abrasive pneumatic grinding wheel refers to a hollow hemisphere composed of a rubber matrix, and a layer of abrasive grains with a certain thickness is softly consolidated on its surface by a polymer binder (which can overcome the use of free airbags in existing airbag polishing. The disadvantage of weak cutting ability of abrasive grains), the flexibility of its surface can be controlled online by the air pressure inside the hollow hemisphere, and it can be conveniently used in conjunction with robots. In the process of finishing high-hardness free-form surfaces, the soft-consolidated abrasive pneumatic grinding wheel is being widely used in various mold surface finishing technologies because of its efficient cutting effect and good self-adaptive characteristics. [0003] However,...
