Description

Technical Field

[0001] The invention relates to the technical field of motor rotor processing, in particular to a motor rotor pickling treatment device and an operating method thereof. Background Art

[0002] After machining, the surface of the existing motor rotor, which is made of silicon steel sheets, will absorb burrs. At the same time, during the machining process, impurities such as machining oil will also be produced on the surface. If not treated, it will have an adverse effect on the loss, efficiency and temperature rise of the motor. By pickling the rotor surface, burrs and oil on the rotor surface can be effectively removed, and the performance of the motor can be improved.

[0003] When pickling the rotor of a motor, the motor rotor is usually directly placed in a clamping device, the two ends of the rotor are clamped by the clamping device, and then the motor rotor is sprayed, and then the motor rotor is scraped and cleaned with a brush. It is difficult to clean the oil stains on the surface of the motor rotor in this way, resulting in poor pickling effect of the motor rotor. Moreover, the existing pickling treatment is mostly carried out under normal pressure, which makes it difficult for the acid to enter the gap between the silicon steel sheets. On the other hand, it is inconvenient to dry the motor rotor after pickling, which reduces the work efficiency.

[0004] Based on this, the applicant proposes a motor rotor pickling treatment device and an operating method thereof. Summary of the invention

The motor is arranged on an adjustment plate, a transmission shaft is arranged on the motor, and the transmission wheel is arranged on the transmission shaft. A driven wheel is arranged on the outer wall of the placement cylinder, the driven wheel on the placement cylinder is connected to the transmission wheel through a belt, and the driven wheels on two adjacent placement cylinders are connected through a belt.

9. The motor rotor pickling treatment device according to claim 8, characterized in that: The outer wall of the placing tube is provided with a fixing groove, and the inner wall of the placing tube is provided with a cleaning brush, and the cleaning brushes are distributed in a spiral shape.

10. An operating method applicable to the motor rotor pickling treatment device according to claim 1, characterized in that: The operation method comprises the following steps: First: Check whether the circuit of the motor rotor pickling device is normal, and check whether the hydraulic cylinder 1, hydraulic cylinder 2, motor and blower can work normally; Second: start hydraulic cylinder 2, hydraulic cylinder 2 and piston rod 2 pull the adjustment plate upward to separate the adjustment plate from the top of the acid barrel, pour acid into the acid barrel, start hydraulic cylinder 1, hydraulic cylinder 1 pushes the material receiving frame upward through piston rod 1, the material receiving frame drives the connecting rod and the push plate at the top of the connecting rod to rise, so that the push plate enters the placing barrel from the bottom of the placing barrel, open the sealing cover at the top of the placing barrel, and put the motor rotors that need to be pickled into the placing barrel in turn. After the electronic rotor is placed, cover the placing barrel with the sealing cover; Third: After the motor rotor is placed, start hydraulic cylinder 1 and hydraulic cylinder 2, push the placement cylinder downward into the acid in the acid barrel, and adjust the sealing ring on the plate to seal the acid barrel; Fourth: start the hydraulic cylinder 1, which pushes or pulls the material receiving frame upwards or downwards through the piston rod 1, and the material receiving frame drives the connecting rod and the push plate at the top of the connecting rod to rise or fall, so that the push plate rises or falls in the placement tube, pushing the motor rotor in the placement tube to rise or fall, and the motor rotor contacts the cleaning brush in the placement tube to clean the electronic surface in the placement tube; Fifth: Start the blower, which blows air into the inner cavity of the adjustment plate through the air supply pipe. The air is sprayed into the acid barrel through the air spray pipe to increase the pressure in the acid barrel. The pressure gauge on the adjustment plate can reflect the pressure in the acid barrel in real time, and the motor rotor is pickled in a high-pressure environment; Sixth: Start the motor, the motor drives the transmission shaft and the transmission wheel on the transmission shaft to rotate, the transmission wheel drives the driven wheel and the placement cylinder to rotate through the belt, the driven wheel on the placement cylinder drives the adjacent placement cylinder to rotate through the belt, the rotating placement cylinder cleans the motor rotor in the placement cylinder, cooperates with the hydraulic cylinder 1, the motor rotor moves vertically in the placement cylinder, and the motor rotor is fully pickled; Seventh: After the motor rotor is pickled, start hydraulic cylinder 1 and hydraulic cylinder 2, move the placement tube out of the acid barrel, start the blower, and blow air into the inner cavity through the air pipe. The air is sprayed out from the air spray pipe to dry the motor rotor in the placement tube. The air flow carries the excess acid on the surface of the motor rotor and flows out from the fixed groove of the placement tube. The push plate moves vertically in the placement tube to quickly dry the motor rotor. Eighth: After the motor rotor is dried, the push plate is moved out from the bottom of the placement barrel under the action of hydraulic cylinder 1, and the dried motor rotor falls from the placement barrel into the receiving frame. The bottom of the receiving frame is an inclined structure, so that the motor rotor rolls to one end of the receiving frame to pickle and dry the motor rotor. After the motor rotor is picked up, the impurities generated by the motor rotor during the pickling and drying process are cleaned and the power is cut off.
