Description

Technical Field

[0001] The utility model relates to the technical field of mechanical pipe polishing, in particular to a surface polishing device for mechanical pipes. Background Art

[0002] In the field of mechanical processing, after the rough processing of parts is completed, the surface of the parts is often rough and has many burrs. Usually, a surface polishing device is required to remove the burrs on the surface of the parts and grind and polish the surface of the parts.

[0003] The prior art provides a polishing device for a surface polisher for pipe processing (Announcement No. CN215700741U), which includes: a base; a first fixing plate, which is installed at one end of the top of the base; a second fixing plate, which is between the second fixing plate and the second fixing plate; and a pipe, which is installed between the first fixing plate and the second fixing plate. The utility model sets a fixing mechanism to realize the sleeve connection of the pipe on the outside of the fixing rod, and then rotates the bolt handle by 90 degrees, so that the bolt handle drives the threaded rod to rotate, thereby driving the cam to move downward, and at the same time, the two ends of the cam squeeze the spring plate, and the spring plate moves along the inner wall of the moving groove, while the reset spring is forced to shrink, so that the spring plate drives the two fixing rods to move along the inner wall of the horizontal groove to the two ends, so as to realize the fast clamping and fixing of the fixing rod to the pipe.

[0004] The polishing device of the surface polishing machine for pipe processing mentioned above only provides the functions of quick clamping and positioning of pipes and clamping and positioning of pipes of different lengths during actual operation. However, when pipes of different diameters need to be clamped and positioned, the position of the positioning mechanism cannot be adjusted, resulting in the positioning mechanism being unable to effectively clamp and fix the pipes, and being unable to rotate the pipes, making it inconvenient to polish the surface of the pipes. Therefore, we need to propose a surface polishing device for mechanical pipes. Utility Model Content
