Description

A large gear finishing device

technical field

The utility model relates to a mechanical device for finish processing, specifically, a device mainly used for finishing the surface of large gear parts with free abrasive tools.

Background technique

The free grinding tool finishing processing method has been paid more and more attention by the industry due to its outstanding advantages such as simple process, strong adaptability, good processing quality and high work efficiency. Many industries originally used manual methods to deburr, grind and polish parts. Machining operations have now been turned to efficient free-form tool finishing methods for processing.

For gear parts, especially the large gears commonly used in wind turbines, with a diameter of 900mm, a thickness of 400mm, and a single weight of about 1 ton, it is a difficult problem in the industry to deburr the outer surface and reduce roughness. Manual files or hand-held grinding wheel (belt) machines can be processed, but the manual method is extremely inefficient and does not conform to the trend of industrial production; it is certainly possible to use the CNC abrasive belt grinding method used in the field of aviation blades, but the multi-axis linkage CNC abrasive The price of belt polishing equipment is very expensive. This is because there are few domestic manufacturers who have mastered the core technology, and most of them need to be imported from abroad; and some models involved in the military industry are prohibited from being exported to China. However, it is a low-cost, high-efficiency and high-quality method for large gears to be finished by using free abrasive finishing technology.

Although the processing effect has been verified, once it involves batch processing, the existing free grinding tool finishing processing method also has the problem of poor manufacturability for processing large gears. Mainly: due to the large thickness of large gears (or tooth width, up to 400mm), it is difficult to perform full-immersion one-time finishing on the full tooth width; due to the large weight, it is very difficult for the existing finishing processing single-machine equipment to get on and off the workpiece , It is impossible to realize batch finishing.

Therefore, it is urgent to develop a new type of skin-finishing device for large-scale gear parts. On the basis of integrating the advantages of high-quality skin-finishing process, batch-scale skin-finishing can be carried out to provide industrialization, Bulk solutions.
