Slot milling tool for motor inner-end ring damping bar connecting slot and using method of slot milling tool

Abstract

The invention discloses a slot milling tool for a motor inner-end ring damping bar connecting slot. The slot milling tool comprises a bearing base, a transmission shaft, a sleeve mould and an inner end ring, and further comprises a power device and a fluted disc, wherein a bearing panel is arranged on the bearing base; the left end of the transmission shaft is connected with the power device; theright end of the transmission shaft sequentially penetrates through the bearing panel and the sleeve mould; the fluted disc is positioned in the bearing panel, and is connected with the transmission shaft; when the power device rotates, the transmission shaft, the fluted disc and the sleeve mould are linked; a gear blocking device which is engaged with or separated from the fluted disc is arrangedon the bearing panel; a locking device capable of locking or loosening the transmission shaft is arranged on the bearing base; and the inner end ring is mounted on the sleeve mould. The slot millingtool is simple in structure, is high in production efficiency, and is high in equipment utilization efficiency. The invention further discloses a using method of the slot milling tool for the motor inner-end ring damping bar connecting slot.

Description

technical field [0001] The invention relates to a groove milling tool, more specifically, a groove milling tool for connecting a damping strip of an inner end ring of a motor. The invention also relates to a method for using the motor inner end ring damping strip connecting slot milling tool. Background technique [0002] The electric motor industry has formed a relatively complete industrial system in China. In recent years, a number of enterprises with large output scale, high product level, good quality and advanced technical equipment have emerged in China's electric motor industry. and production capacity can basically meet the needs of domestic national economic development. [0003] The motor damping winding is used to damp the disturbance of the power system, and the second is to provide a path for the induced current generated in the rotor by the reverse rotating magnetic field generated by the negative sequence current in the stator winding. The damping winding c...
