[0002] In the field of automated precision belt grinding, there are various types of grinding, such as hanging belt grinding and contact wheel belt grinding. For parts with size and shape requirements, contact wheel belt grinding is generally used. This method makes it easier to control the grinding size and accuracy. At present, the contact wheel bracket is usually fixed to the force control component on the side with two bolts and two locking bolt holes. It is inconvenient to replace the contact wheel or disassemble the contact wheel bracket. The second problem is that the contact wheel bracket is fixed on the side of the force control component. Due to the effect of the component force, there is a corresponding deviation in the control of the grinding force.

[0003] Therefore, in view of the above situation, it is urgent to develop a reliable and fast replacement grinding contact wheel bracket to overcome the shortcomings in current practical applications. Utility Model Content

[0008] According to a further technical solution, the abrasive belt, the grinding contact wheel and the deviation correcting wheel are on the same axis.

[0009] A further technical solution is that the sanding belt correcting wheel assembly includes a correcting wheel base plate, an adjusting handle, a swing shaft and a correcting wheel; the correcting wheel base plate is fixedly connected to the upper end surface of the bracket base, and one end of the correcting wheel base plate is rotatably connected to the adjusting handle; the upper end of the correcting wheel base plate is rotatably connected to the swing shaft, and the swing shaft is meshed with the rotating shaft of the adjusting handle; correcting wheels are rotatably connected to both sides of the correcting wheel base plate, and one of the correcting wheels is fixedly connected to the swing shaft.

[0010] According to a further technical solution, an end face limit block is fixedly sleeved on the middle portion of the grinding contact wheel bracket, and the end face limit block abuts against the end face of the bracket base.

[0011] In summary, the embodiments of the present invention have the following beneficial effects compared with the prior art:

[0012] 1. The grinding contact wheel bracket can be quickly installed;

[0013] 2. The grinding contact wheel bracket has high repetitive installation accuracy;

[0014] 3. The force control components are evenly stressed, and the force feedback is more stable and reliable;
