In the above technical solution, the swing arm motor is a servo motor control motor; the swing arm motor uses the servo motor control to control the force and speed of the swing arm against the product when the product is polished to control the operation of the automatic sander.

The beneficial effects of the creation are as follows: First, the automatic grinding mechanism consists of a grinding head, a swing arm frame, a grinding motor, a swing arm motor and a lifting motor. When the burr of the product is polished, the swing arm frame and the swing arm motor are passed. And the function of the lifting motor, driving the grinding head to make contact with the product burr, and the fixed thrust is close to the burr of the product. Since the polished product has an irregular shape, the grinding head undulates with the shape of the product when the product rotates, and the grinding head and the grinding head are The burr of the product has always maintained a fixed thrust. When the product rotates for one week, the grinding head also polishes the burrs of the product for one week. The grinding process and the completion of the grinding process, regardless of the shape of the product, the grinding head can fit the surface movement of the product, so this creation The automatic grinding machine can polish any shape of the product, and its application range is very wide. Secondly, the creation of the grinding motor is controlled by the frequency converter, so the rotation speed of the grinding head can be changed at will to achieve the required grinding effect; The creation is provided with a rotating mechanism that can rotate the grinding product at any angle, thus realizing the product Each part is polished, and the number of rotations and rotation speed of the product during grinding can be set. Fourthly, the automatic sanding machine of the present invention can reduce the air pollution during polishing, reduce the health hazard to the operator, and improve the product. Production efficiency, stable structure and good grinding effect.
