[0005] A precision part is dirty with clamping device, including cleaning platform, the cleaning platform is provided with positioning seat, the center of positioning seat is provided with the through hole of dirty removal coaxially, the periphery of the through hole of dirty removal is provided with motor shell slot, the bottom of motor shell slot is provided with tool cavity, the tool cavity is provided with clamping tool and drive end.
[0006] Further, the motor shell slot includes at least three, the motor shell slot is distributed around the edge of the through hole of dirty removal, and each motor shell slot is evenly distributed.
[0007] Further, the motor shell slot is communicated between the through hole of dirty removal, and the tool cavity is one-to-one corresponding with the motor shell slot.
[0008] Further, the drive end is a pneumatic cylinder, the clamping tool includes a front cover plate, and the front cover plate is in the through hole of dirty removal.
[0009] Further, the inner side of the front cover plate is provided with a stop protrusion, the stop protrusion is in contact or separated from the inner wall of the motor shell, and the height of the front cover plate is less than or equal to the notch position of the motor shell slot.
[0010] Further, the front cover plate is connected with the L-shaped plate; the other end of the L-shaped plate is connected with the piston of the cylinder; and the cleaning table is provided with a drainage opening opposite the dirt removal through hole.
[0011] Further, the drainage opening is provided with a water storage container below.
[0012] The utility model has the following beneficial effects: firstly, in the design, the motor shell workpiece is fixed in the vertical posture, so that the motor shell is coaxially arranged with the positioning seat and the dirt removal through hole, since the motor shell has a hollow chamber, the upper side can be flushed and wiped, and the lower side can directly discharge the cleaning sewage, so that sewage residue is avoided. At the same time, the design avoids positioning from the workpiece surface, but uses the abutting convex to clamp the shell from the inside, realizes the tensioning and fixing of the motor shell, and in this way, the clamp cover area is small, and the clamp tool structure is simple.
