Machining method for manufacturing motor rotor punching sheet

Abstract

The invention relates to a machining method for manufacturing a motor rotor punching sheet. The method mainly comprises the following steps of polished section punching, punched sheet separation, punching operation, polishing operation, detection processing, statistical counting and the like. Used rotor punching sheet grinding equipment comprises a bottom plate, a grinding device, a rotary positioning device and a clamping device. The machining method can be used to solve the following problems existing in grinding of an existing rotor punching sheet: a, a grinding machine is commonly used forgrinding the rotor punching sheet at present, a phenomenon that a slotted hole is not ground or excessive grinding occurs easily when the grinding machine grinds, and production quality of the rotorpunching sheet is reduced, and cost is wasted; and b, only a single rotor punching sheet can be ground when the traditional rotor punching sheet is ground, grinding efficiency is low, a defective rateof products is high, polishing conditions of the rotor punching sheets are inconsistent, and the rotor punching sheets are extremely easy to scrap. A yield of the rotor punching sheets and the grinding efficiency of the rotor punching sheets can be improved.

Description

technical field [0001] The invention relates to the technical field of motor processing, in particular to a machining method for making a punched sheet of a motor rotor. Background technique [0002] At present, motors are widely used in transportation, construction, industry and other fields. The motor is mainly composed of a stator and a rotor. The motor rotor is an indispensable and important part of the motor. The motor rotor is mainly composed of multiple rotor punches. There is a rotating shaft hole in the middle of the rotor punching sheet. After stacking, the rotating shaft holes on the rotor punching sheet are connected to each other, and then the rotating shaft is installed in the rotating shaft hole for use. The motor rotor will have a lot of burrs after stamping. It is necessary to clean the burrs on the motor rotor. Grinding treatment. [0003] However, the following problems exist in the existing rotor punching and grinding. a. At present, a grinder is often u...

Problems solved by technology

[0003] However, the following problems exist in the existing rotor punching and grinding. a. At present, a grinder is often used for rotor punching and grinding. The production quality of the punching sheet is a waste of cost; b, when the traditional rotor punching is polished, only a single rotor punching can be polished, the grinding efficiency is low, the product defective rate is high, and the grinding status of the rotor punching is inconsistent, which is easy to Leading to the scrapping of rotor punching, it can improve the yield of rotor punching and the grinding efficiency of rotor punching
