Description

Technical Field

[0001] The utility model relates to the technical field of grinding tooling, in particular to a part plane grinding tooling. Background Technique

[0002] In the process of steel processing, it is often necessary to grind the surface of parts. At this time, workers need to use hand-held sandpaper to grind the parts. Holding the sandpaper all the time will cause workers to be easily fatigued and prone to accidents. Therefore, it is particularly necessary to develop a grinding tooling that can replace workers holding sandpaper.

[0003] As disclosed in a Chinese patent: a part plane grinding tooling, patent number: CN210255679U, converts the rotation of the power output shaft of the reducer into the movement of a long rod in the left-right direction through a crank. The sandpaper grinds the surface of the workpiece in the left-right direction driven by the long rod. The hanging ring can increase the downward pressure of the grinding sheet by suspending a heavy object, making the grinding effect better. However, in the process of implementing the above technical solution, it is found that there are at least the following technical problems: as described above, the length of the long rod of the device is fixed. When grinding parts of different sizes, it may be necessary to frequently replace the long rod, which increases the complexity and time cost of the work and is not convenient for the staff to grind and use.
