Description

Technical Field

[0001] The utility model relates to the technical field of motor maintenance, in particular to a wire pulling machine for a motor stator. Background Art

[0002] In recent years, with the development of the national economy, various lifting equipment has become popular. Due to the harsh operating environment of lifting equipment, the motor often burns out. When repairing the motor, it is necessary to remove the damaged old winding of the motor stator winding. Our previous removal method is to remove the motor stator coil by hand, which is time-consuming and labor-intensive, and the wire pulling efficiency is low and very slow, and the labor intensity of workers is high. For this reason, we propose a wire pulling machine for motor stator. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a wire pulling machine for a motor stator. The motor stator is fixed on the fixed component, and then the hydraulic cylinder is controlled to work by an external controller. The hydraulic cylinder works to drive the sliding bracket to move right on the sliding groove, and the sliding bracket moves right to drive the connecting bracket to move right. At the same time, the electric push rod drives the regular triangular prism to move right, so that the two inclined plates respectively conflict with the side surfaces of the regular triangular prism. When the two wire pulling clamps can clamp the stator coil, the electric push rod drives the regular triangular prism to move left, and a distance for the two wire pulling clamps to move outward when clamping the coil is reserved, so that the two wire pulling clamps clamp the coil under the tensioning action of the strong compression spring, and then the hydraulic cylinder works to drive the wire pulling clamp to move left to pull out the coil. When the two inclined plates conflict with the side surfaces of the regular triangular prism again, the two wire pulling clamps separate to take out the wire, thereby working in a reciprocating manner to pull the wire of the motor stator coil. Not only can the wire pulling efficiency of the motor stator coil be improved, but also the labor intensity of workers can be reduced, and the problems in the background technology can be effectively solved.
