Description

Technical Field

[0001] The present invention relates to the technical field of rotating shaft processing, in particular to a motor rotating shaft processing device and a processing method thereof. Background Art

[0002] The motor shaft is the core component of the motor, responsible for transmitting torque, supporting rotor rotation, and withstanding mechanical and electromagnetic loads. It supports the rotor core and windings, transmits motor torque, and ensures a uniform air gap between the rotor and stator. Its machining quality directly impacts the motor's efficiency, vibration, noise, and lifespan.

[0003] Application No. 202310693113.3 discloses a motor shaft finishing device and its processing technology, including a processing table and a motor shaft. The processing table is provided with a clamping device for clamping the motor shaft. The clamping device includes a clamping cylinder that is sleeved and clamped on both sides of the motor shaft. The outer end of the clamping cylinder on the left is fixedly connected to a rotating shaft, and the rotating shaft is connected to a driving motor through a coupling; a grinding cylinder is sleeved on the outer side of the motor shaft, and a grinding block that abuts the motor shaft is installed in the grinding cylinder; a reciprocating screw assembly that drives it to move back and forth horizontally is connected to the top of the grinding cylinder; it is convenient to realize the rapid switching between the two modes of overall reciprocating grinding and local repeated grinding, replace manual operation, and improve the stability and grinding effect of the grinding operation.

[0004] Compared with the traditional technical solution, the above technical solution can realize reciprocating grinding and local repeated grinding, but the processing scenario is single and can only process conventional cylindrical shafts. However, some shafts are designed in a D-shape, and the design of the straight surface part is to solve problems such as torque transmission, assembly accuracy and manufacturing efficiency. The edge part between the arc part and the cross section of the D-shaped shaft requires special fillet transition treatment. The core of the processing of the D-shaped shaft lies in the dynamic balance control of the transition treatment. The above technical solution cannot grind the fillet part of the edge. If only local repeated grinding is used without controlling the movement speed of the grinding block, the contact area between the grinding block and the shaft increases, and the grinding amount per unit time increases, resulting in excessive local temperature rise and affecting the material microstructure. It may also cause the shaft, such as the arc area, to be over-grinded, resulting in unstable finished product effect of the shaft, and it is also impossible to perform rust prevention treatment on the grounded part of the shaft.

[0026] In order to further realize the grinding of different positions of the shaft in the present invention, Figure 2 As shown, slide grooves 5 are provided on the left and right sides of the upper end surface of the workbench 1, and sliders 6 are provided on the left and right sides of the lower end surface of the support plate 4. The sliders 6 slide inside the slide grooves 5. The output end of the first motor 7 is fixedly connected to the driving screw 11, and the mounting bracket 8 is threadedly connected to the surface of the driving screw 11. The right side of the upper end surface of the workbench 1 is fixedly connected to the limiting block 9, and the driving screw 11 is rotatably connected to the limiting block 9.

[0027] A method for processing a motor shaft processing device comprises the following steps: Step A: The clamping frame 2 clamps and fixes the rotating shaft 3 to be processed; Step B: The first grinding mechanism 100 grinds the arc portion of the rotating shaft 3; Step C: the driving mechanism 200 controls the second grinding mechanism 300 to grind the connection between the cross section and the arc surface of the rotating shaft 3; Step D: The anti-rust mechanism 400 performs anti-rust work on the polished part.

[0028] Furthermore, when the driving mechanism 200 performs the grinding work, as the contact area between the wedge-shaped grinding block 305 and the rotating shaft 3 gradually increases, the cam 209 rotates to control the buckle 210 to move downward, thereby reducing the movement speed of the wedge-shaped grinding block 305 by reducing the transmission ratio of the transmission belt 206, thereby ensuring the grinding consistency between the transition area and the plane. When the wedge-shaped grinding block 305 gradually disengages, the cam 209 controls the buckle 210 to move upward to achieve the tension of the transmission belt 206, so that the wedge-shaped grinding block 305 can be quickly withdrawn to avoid excessive grinding in the edge area.

[0029] Working principle: The clamping frame 2 fixes the rotating shaft 3 to be processed, and the grinding wheel 106 grinds the arc surface of the rotating shaft 3. If the contact point between the grinding wheel 106 and the rotating shaft 3 needs to be adjusted, it can be achieved by adjusting the position of the adjusting block 103 in the arc groove 107 and the rotation angle of the hinge plate 105. By rotating the adjusting block 103, the extension length of the adjusting screw 102 is controlled. The second motor 202 and the third motor 207 respectively drive the output shaft 203 and the matching shaft 208 fixedly connected thereto to rotate, the output shaft 203 drives the active rotary wheel 204 fixedly connected thereto to rotate, the active rotary wheel 204 drives the driven rotary wheel 205 to rotate through the transmission belt 206, the driven rotary wheel 205 drives the driving plate 301 fixedly connected thereto to rotate, the driving plate 301 drives the transmission shaft 302 fixedly connected thereto to rotate, when the transmission shaft 302 rotates, it drives the driving frame 303 sliding on its surface to reciprocate left and right, the driving frame 303 drives the fixed plate 304 fixedly connected thereto to reciprocate back and forth, and the fixed plate 304 drives the wedge-shaped grinding block 305 to reciprocate left and right When the wedge-shaped grinding block 305 moves to the left, its wedge surface portion gradually increases the contact area with the edge portion. At this time, the protruding portion of the cam 209 fixedly connected to the matching shaft 208 rotates to the lower side, and the bearing plate 211 on its surface moves downward according to its own gravity, so that the upper and lower parts of the transmission belt 206 are in a parallel state. By reducing the tension of the transmission belt 206, the transmission ratio of the active runner 204 to the driven runner 205 is reduced, so that the rotation speed of the driven runner 205 is reduced, thereby reducing the speed of the wedge-shaped grinding block 305 moving to the left, ensuring the grinding consistency of the transition area and the plane, and then achieving the goal that the grinding speed of the wedge-shaped grinding block 305 decreases as the contact area increases, keeping the grinding force stable, and avoiding heat concentration affecting the grinding effect; When the wedge-shaped grinding block 305 is released from contact with the rotating shaft 3 and moves to the right, the third motor 207 has controlled the protruding part of the cam 209 to rotate upward, and the protruding part of the cam 209 pushes the carrying plate 211 to move upward, and the carrying plate 211 drives the buckle 210 fixedly connected thereto to move upward, and the buckle 210 pulls the transmission belt 206 to increase its tension, thereby increasing the transmission ratio by increasing the friction with the output shaft 203 and the driven runner 205. At this time, the movement speed of the wedge-shaped grinding block 305 will be further accelerated, ensuring that the wedge-shaped grinding block 305 is accelerated when it exits the contact, avoiding staying in the edge area for too long and causing excessive grinding, thereby achieving linear deceleration of the wedge-shaped grinding block 305 when the contact area with the rotating shaft 3 increases, then grinding the transition area at a low and uniform speed, and finally linearly accelerating and disengaging during the exit stage, thereby achieving a constant material removal rate of the rotating shaft 3, ensuring its surface uniformity and the service life of the wedge-shaped grinding block 305; While grinding, the fixed plate 304 drives the two-way piston rod 402 fixedly connected thereto to perform left and right reciprocating motion, and the two-way piston rod 402 controls the two output ends of the double-chamber piston cylinder 401 to alternately spray out the rust preventive agent. When grinding, the rust preventive agent is sprayed onto the cross section of the rotating shaft 3 and the surface of the wedge-shaped grinding block 305 through the first nozzle 404, while performing a certain temperature reduction treatment on the rotating shaft 3. When the wedge-shaped grinding block 305 is away from the rotating shaft 3, the two-way piston rod 402 moves rapidly along with the fixed plate 304, causing the double-chamber piston cylinder 401 to spray more rust preventive agent, and the rust preventive agent is concentratedly sprayed onto the edge portion of the rotating shaft 3 through the second nozzle 405, further improving the grinding effect of the rotating shaft 3. The driving frame 303 drives the transmission screw 503 fixedly connected to it to perform reciprocating left and right motions. When the transmission screw 503 moves to the right, it enters the interior of the liquid storage tank 501. When the inner side wall of the liquid storage tank 501 limits the annular frame 504, the movement of the transmission screw 503 will drive the stirring blade 505 threadedly connected to it to rotate, thereby stirring and mixing the rust inhibitor, further improving the rust prevention effect on the rotating shaft 3. Furthermore, when the wedge-shaped grinding block 305 moves rapidly to the right, the transmission screw 503 will also drive the annular frame 504 to stir and rotate more quickly, thereby achieving a more uniform stirring effect. The rust inhibitor is sprayed on the polished edge of the rotating shaft 3 through the double-chamber piston cylinder 401.
