Description

Technical Field

[0001] This utility model relates to the field of polishing mechanisms, and in particular to a CNC multi-row polishing mechanism. Background Technology

[0002] Polishing is a processing method that uses mechanical, chemical, or electrochemical processes to reduce the surface roughness of a workpiece, thereby obtaining a bright and smooth surface. It involves using polishing tools and abrasive particles or other polishing media to refine the surface of a workpiece.

[0003] In the processing of small metal products, manual processing is generally used to process them one by one. With the development of automation, although some products are processed one by one using conveyor belts, there are multiple surfaces that need to be polished for such products, and there are processing blind spots (i.e., non-polished areas) between polished surfaces, which increases the processing difficulty. Therefore, the processing method of conveyor belts also has significant limitations. Thus, how to achieve polishing of non-standard products has always been a key design issue. Utility Model Content

[0004] The main purpose of this invention is to propose a CNC-controlled polishing mechanism, which aims to improve existing polishing mechanisms, achieve automated polishing, and has a simple and stable structure.

[0005] To achieve the above objectives, this utility model proposes a CNC multi-row polishing mechanism, comprising: A fixture having a matrix of positioning slots for placing a product and allowing the polished surface of the product to extend out of the positioning slots; The movable frame includes a base, a vertical movable frame with the base, a horizontal movable frame disposed on the vertical movable frame, and a longitudinal movable frame disposed on the horizontal movable frame. The longitudinal movement frame is equipped with a positioning device, which is used to limit the movement of the fixture. The movable frame is used to drive the fixture to move vertically, laterally, and longitudinally; A polishing device, comprising a base, a rotary motor mounted on the base, and a polishing brush connected to the rotary motor.

[0006] In actual design, the products are first placed on a fixture and arranged in an array. The fixture moves vertically via a positioning device, bringing the first product in a column or row into contact with the next product. Then, a lateral moving frame moves the product group laterally, and the product group is polished. After polishing is complete, polish the adjacent product groups. This enabled automated processing of the products and improved processing efficiency. Attached Figure Description
