Problems solved by technology

[0004]1. Since the hydrochloric acid solution is applied to the surface of the rotor at normal temperature for acid treatment, the hydrochloric acid solution will interact with the aluminum filings in the rotor core at normal or low temperature. And the chemical reaction of surface burrs is slow, which affects the pickling effect
[0005]2. Since the rotor enters the drying process after pickling, the residual hydrochloric acid solution on the surface of the rotor cannot be effectively treated, and the residual hydrochloric acid solution will corrode the rotor. Not only affect the performance of the motor, but also affect the service life of the rotor

Embodiment Construction

[0021] see figure 1 , the process steps of the process of the present invention are:

[0022] Step 1: Pre-heat the rotor;

[0023] Step 2: Pickle the surface of the rotor with the prepared acid solution;

[0024] Step 3: Clean the surface of the rotor with water;

[0025] Step 4: Dry the cleaned rotor.

[0026] For the pre-heating treatment of the rotor, an infrared heating device can be used. Generally, the surface of the rotor is heated to 60 ℃ ~ 80 ℃; the acid solution can be hydrochloric acid solution or phosphoric acid solution. When phosphoric acid solution is used, the ratio of phosphoric acid to water is usually The ratio is 1:3~5; the drying of the cleaned rotor can be done by an infrared drying device.

[0027] In the process operation of the first step to the fourth step, the rotor rotates along its axis, and the rotor rotates continuously under the operating conditions of each process, so that each part of the rotor surface can be treated correspondingly, which...

Abstract

The invention discloses a motor rotor surface pickling burring technology, and relates to the motor manufacturing field. The technology comprises the following steps: 1, preheating a rotor; 2, pickling the surface of the rotor through using a prepared acid solution; 3, cleaning the surface of the rotor with water; and 4, drying the cleaned rotor, wherein the rotor rotates along the axis of the rotor during the step 1-4; and the rotator is supported by two supporting rollers of a supporting roller assembly, and the two supporting rollers homodromously rotate to drive the rotor to rotate. The technology has the characteristics of effective improvement of the pickling processing effect, production efficiency increase and the like.

Description

technical field [0001] The invention relates to the field of motor manufacturing, in particular to a production process for removing burrs and aluminum chips on the surface of a motor rotor during the manufacturing process. Background technique [0002] The asynchronous motor consists of two parts, the stator and the rotor. The rotor is a cast aluminum part (ie, iron core) including silicon steel sheets. During the production process, the cylindrical surface of the die-cast aluminum rotor needs to be turned. Aluminum filings will enter the rotor core and produce burrs (aluminum whiskers) on the rotor surface. These aluminum filings and burrs must be removed before assembly to reduce the core loss and load stray loss of the motor rotor. Otherwise, the performance of the magnetic field and the efficiency of the motor will be reduced. [0003] The patent document with the application number 200410093271.2 discloses a "motor rotor surface pickling treatment process". The steps ...
