The upper surface of the positioning plate is also fixedly provided with a positioning block. The positioning block is a V-shaped block, and the positioning block and the positioning plate are positioned through a cylindrical pin. Some castings are irregular shapes, if the castings are provided with protruding parts, the protruding parts need to be separately positioned and supported, the shapes and the sizes of positioning blocks can be selected according to the shapes of the protruding parts, if the castings are cylindrical, V-shaped blocks can be selected for positioning and supporting, the positions and the angles of the V-shaped blocks can be designed according to the shapes of the castings, and the positioning blocks and the positioning plates are positioned through cylindrical pins to guarantee position accuracy.

The device is specifically operated, the device is assembled when in use, the base is fixed on a workbench of a machining center through bolts, a casting is sleeved on the positioning core, the cylindrical end face is placed on the positioning block, and the elongated opening on the pressing plate is inserted and sleeved on the rod part of the pull rod. And starting the numerical control system, driving the pull rod to move downwards by the piston rod of the air cylinder, and driving the pressing plate to press the casting by the upper end part of the pull rod to finish the compression of the casting. The cutter of the machining center moves along the periphery of the casting to remove the flash. After the flash is completely removed, a piston rod of the air cylinder drives the pull rod to move upwards, the lower end part of the pull rod drives the pressure plate to leave the casting, so that the casting is loosened, then the pressure plate is drawn out, and the casting is taken out.

The beneficial effects of the invention are that the utility model discloses a casting overlap removing, positioning and clamping device can be placed on the workbench of a processing center, and through the control of a numerical control system, the speed of casting overlap cleaning is improved, and the uniformity of the overall dimension of the cleaned casting is good. The device is adopted to clean the flash without generating dust, so that the working environment is cleaner. The whole device has the advantages of simple structure, convenient operation, low cost, saving of a large amount of manpower labor and high yield.
