Walking polishing device for inner wall of small-diameter cylinder

Abstract

The invention provides a walking polishing device for the inner wall of a small-diameter cylinder. The walking polishing device comprises a rotary polishing part, a rotary driving mechanism and a walking driving structure. The front end of the rotary driving mechanism is provided with the rotary polishing part, and the rear end is provided with the walking driving structure; at least one polishing wheel is installed on the rotary polishing component through a polishing wheel fixing mechanism, and the polishing wheel fixing mechanism can rotate relative to the rotary driving mechanism along the center position of the rotary polishing component. In-cylinder walking and rotary polishing can be executed through rotary driving and walking driving correspondingly, and practicability and universality are high; the problems of deformation and poor roundness caused by machining precision difference of the inner wall of the barrel can be solved; and the polishing device is convenient to mount and detachable, and can be used for polishing the inner walls of barrel products of different specifications or materials.

Description

technical field [0001] The invention relates to a walking polishing device for the inner wall of a cylinder with a small diameter. Background technique [0002] The inner wall polishing operation of cylinder products is usually a key process that affects product quality. After years of development, domestic cylinder inner wall polishing operations have developed two main polishing methods: polishing machine and cantilever polishing arm, gradually moving towards intelligent , diversification, and more and more equipment and devices for polishing operations, but in the work, when most cylinder products need to be polished on the inner surface, it is often limited by the diameter of the cylinder and the size of the cylinder. length, it is difficult to polish the target position or the entire inner wall of the cylinder. Although some shorter inner walls of the cylinder can be polished manually, it is easy to cause safety hazards due to the limitation of the curvature of the inne...

[0002] The inner wall polishing operation of cylinder products is usually a key process that affects product quality. After years of development, domestic cylinder inner wall polishing operations have developed two main polishing methods: polishing machine and cantilever polishing arm, gradually moving towards intelligent , diversification, and more and more equipment and devices for polishing operations, but in the work, when most cylinder products need to be polished on the inner surface, it is often limited by the diameter of the cylinder and the size of the cylinder. length, it is difficult to polish the target position or the entire inner wall of the cylinder. Although some shorter inner walls of the cylinder can be polished manually, it is easy to cause safety hazards due to the limitation of the curvature of the inner wall of the cylinder, and for longer cylinders , the human body can hardly enter its interior or it is difficult to reach into the cylinder with the help of external cantilever tooling for polishing operations, which is time-consuming and laborious and affects product processing efficiency
