Clamping piece for shell machining

The utility model belongs to the technical field of shell machining, particularly relates to a clamping piece for shell machining, and aims to solve the problems that an existing clamping part cannot be adjusted, manual adjustment is needed during multi-angle shell machining, and the clamping part is prone to being changed. The clamping mechanism is located at the bottom of the box body, the clamping mechanism comprises two clamping boxes, a first sliding way is formed in the bottom of the box body, the two clamping boxes are slidably connected into the first sliding way, clamping blocks are slidably connected to the inner walls of one sides of the two clamping boxes, and the adjusting assemblies are arranged at the tops of the clamping blocks. According to the shell polishing device, the shell is clamped and adjusted through the adjusting assembly and the limiting mechanism, the shell can be clamped, the angle of the shell can be adjusted, the stability of the shell can be guaranteed after the shell is adjus
