3. The casting deburring device of claim 1, wherein the lower end of the main arm is provided with a high-speed motor bracket to which the high-speed motor is fixed, and the grinding head is fixed to a rotating shaft of the high-speed motor.
4. The casting deburring device according to claim 2, wherein a travel switch frame is arranged on one side of the clamp body, and the clamp travel switch is arranged on the travel switch frame;
and a travel switch feeler lever matched with the clamp travel switch is arranged on the telescopic rod of the transverse moving hydraulic cylinder.
5. The casting deburring device according to claim 2, wherein an electrical cabinet is fixed on the main shaft, and an electrical switch for controlling the on-off of the circuit of the whole device is arranged on the electrical cabinet for emergency stop of an emergency.
6. A method of operating a cast deburring device as claimed in claim 5, comprising:
the casting is placed on the fixture body by a worker, the traversing hydraulic cylinder moves right to lock the casting, then the lifting hydraulic cylinder descends to drive the base arm and the main arm to descend, the grinding head gradually approaches the casting, when the grinding head contacts the casting, the high-speed motor works, the worker manually controls the traversing and rotation of the main arm in the horizontal plane to enable the grinding head to contact with burrs of the casting, the burrs are removed through the rotation of the grinding head, the grinding head is manually controlled to reach the edge line of the removed burrs, and the removal of all burrs of the casting is completed;
after the burrs are removed, the lifting hydraulic cylinder is lifted to a certain height, the traversing hydraulic cylinder is moved left to loosen the clamp body, a new casting with the pre-burrs is manually removed and replaced, and the actions are repeated to carry out the next round of deburring.
7. The method for operating a casting deburring device according to claim 6, wherein the process of clamping the casting by the clamp body is:
the piston rod of the traversing hydraulic cylinder extends out to push the wedge to move right through the right push wedge push rod, and the push rod is pushed to move upwards because the upper surface of the wedge is a slope in the right direction, so that the push rod pushes the inner expansion block push rod to move upwards, the inner expansion block is caused to spread to two sides, the outer diameter is continuously spread, and the outer wall of the inner expansion block is contacted and clamped with the inner wall of the casting;
when the burrs of the casting are removed, the piston rod of the traversing hydraulic cylinder is retracted, the wedge iron moves leftwards, and when the travel switch contact rod touches the fixture travel switch, the traversing hydraulic cylinder stops leftwards moving, the casting loosens, and the new casting with the pre-burrs is removed.
