Automatic polishing machine

Abstract

The invention relates to an automatic polishing machine. The automatic polishing machine comprises a rack (1), wherein a working table turnplate die set mechanism (5) is arranged on the rack (1); four jig systems (6) are fixed to the working table turnplate die set mechanism (5); three disc polishing systems (7) separately used for rough grinding, fine grinding and polishing are arranged at the periphery of the working table turnplate die set mechanism (5); the working table turnplate die set mechanism (5) can drive the four jig systems (6) to rotate; the jig systems (6) are used for fixing products (A) and copying limiting cam blocks (6-8) and driving the products (A) and the copying limiting cam blocks (6-8) to rotate; the three disc polishing systems (7) are separately provided with one grinding disc (7-8) and one limiting flat block (7-7) and can drive the grinding discs (7-8) to approach the products (A); and the copying machining of the products (A) is realized through the contact of the limiting flat blocks (7-7) and the copying limiting cam blocks (6-8). The automatic polishing machine can automatically polish specially shaped pipe shaft components, increase the production efficiency and the product quality first-pass rate, reduce losses and reduce the technical cost.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a polishing device, in particular to an automatic polishing machine, in particular to an automatic polishing machine capable of rough grinding, fine grinding and polishing of special-shaped pipe shaft parts. Background technique [0002] Shaped pipe shaft is a commonly used component. In order to ensure its accuracy, etc., it is necessary to grind and polish the special-shaped tube shaft. For the industry, there are two existing methods for the grinding and polishing of special-shaped pipe shafts: one is manual grinding and polishing. However, this method completely depends on the manual skill level of the operator to determine the grinding quality of the product shape. It has high requirements for employees, and it is easy to grind and collapse the special-shaped parts of the product. The quality cannot be controlled, and the production efficiency is not high, and t...

Problems solved by technology

However, this method relies entirely on robots to imitate the actions of human hands for processing, and the work efficiency is low.

In addition, because the shape of the product is irregular, it is necessary to ensure the appearance contour of the product after grinding, so the control accuracy of the robot's back axis is relatively high, and the unit processing cost is relatively high, which is not suitable for mass production.
