Description

Technical Field

[0001] The present invention relates to the technical field of motor spindle detection, and in particular to a three-phase asynchronous motor spindle detection device. Background Art

[0002] As a core component for transmitting torque and supporting the rotor, the surface integrity of the motor shaft directly affects the reliability and life of the entire machine. Any slight surface defect can become a stress concentration point, accelerating fatigue expansion under high-speed operation and cyclic loads, ultimately leading to shaft fracture or deformation, catastrophic equipment failure, unplanned downtime, and even safety accidents. At the same time, surface roughness or geometric anomalies can interfere with bearing fit accuracy, increase vibration and noise, accelerate bearing wear, and reduce energy efficiency. Strict surface defect detection is not only a key quality control link to ensure the long-term stable operation of the motor and meet the design life, but also a necessary measure to prevent potential failures, reduce maintenance costs, and ensure user safety and brand reputation.

[0003] The spline groove is the core meshing structure for precise torque transmission between the motor shaft and transmission components such as couplings and gears. Wear in this area after load operation will directly destroy its precise fit: on the one hand, it will lead to a decrease in torque transmission capacity, resulting in slippage, vibration or abnormal noise, affecting the driving accuracy of the equipment; on the other hand, it will aggravate the uneven stress distribution and accelerate the vicious cycle of wear, which may cause catastrophic failures such as spline tooth breakage or shaft distortion. Metal debris generated by wear will also contaminate the lubrication system and accelerate the wear of bearings and gears. Regularly testing the amount of spline groove wear can predict the life of the transmission system, avoid sudden downtime, and provide a key basis for optimizing material selection, heat treatment processes and lubrication solutions. It is a necessary measure to ensure high-reliability operation of equipment and prevent major losses.

This device replaces manual spline sleeve assembly with automatic spline sleeve assembly, improving spline assembly efficiency and automatically achieving load-running-in of the splines.

When the wiping heads 208 are driven to slide on the wiping plates 207, the wiping heads 208 gradually approach the motor shaft 106, and a wiping cloth is provided on the end of the wiping heads 208 facing the motor shaft 106. The wiping head 208 wipes the motor shaft 106.

A magnetic powder brake is provided in the load frame 305, and the load frame 305 limits the rotation of the receiving disk 306 through the magnetic powder brake. The magnetic powder brake changes the torque applied to the receiving disk 306 at the position of the motor shaft 106 when it rotates by limiting the receiving disk 306. An adjustment block 5 308 is also slidably provided on the upper end of the detection frame 2 301, and two groups of wiping heads 2 310 are slidably provided in the adjustment block 5 308 to wipe The second head 310 wipes the surface of the motor shaft 106.

The fitting frame 307 is driven by a hydraulic cylinder. Multiple groups of friction rollers 309 are rotatably set on the fitting frame 307. When the fitting frame 307 is driven to slide on the mounting frame 302, the fitting frame 307 drives the friction roller 309 to fit with the motor shaft 106. By changing the pressure of the hydraulic cylinder on the fitting frame 307 on the fitting frame 307, the pressing force of the friction roller 309 on the motor shaft 106 is changed. The friction roller 309 and the magnetic powder brake on the load frame 305 are synchronized to adjust the load on the motor shaft 106. Multiple groups of cameras are set at the lower end of the second detection frame 301. The cameras detect the degree of wear of the spline groove on the motor shaft 106 through visual analysis by taking pictures.

[0034] Working principle: When working, the motor shaft 106 is placed between the two groups of clamping plates 116, and the two groups of clamping plates 116 are driven to approach each other to clamp the motor shaft 106, and the transfer frame 105 is driven to rotate on the transfer plate 104 to change the direction of the motor shaft 106. When the motor shaft 106 is toward the cleaning component 2, the transfer plate 104 is driven to slide on the base two 103, and the transfer plate 104 drives the transfer frame 105 and the motor shaft 106 to move. After the motor shaft 106 is aligned with the positioning frame three 202 and the cleaning frame 204, the positioning frame three 202 is driven to approach the motor shaft 106, and at the same time, multiple groups of clamping rings 209 are driven to approach each other, and the clamping ring 209 clamps one end of the motor shaft 106, and the cleaning frame 204 is driven to slide on the base three 201, and the cleaning frame 204 is close to the motor shaft 106. The cleaning frame 204 drives the fixing plate 205 and the support plate 210 to fit with the other end of the motor shaft 106. After the support plate 210 is in contact with the motor shaft 106, the cleaning frame 204 continues to be driven to move. At this time, the fixing plate 205 and the motor shaft 106 are fixed and do not move. The cleaning frame 204 moves on the base three 201 and the fixing plate 205. At the same time, the cleaning frame 204 compresses the spring two 206. While the cleaning frame 204 moves, it drives multiple groups of wiping heads 208 to approach the motor shaft 106. The wiping head 208 contacts the surface of the motor shaft 106 and wipes the motor shaft 106. When the wiping plate 207 is driven to slide on the cleaning frame 204, it drives multiple groups of wiping heads 208 to move. At the same time, the positioning ring 203 is driven to rotate on the positioning frame three 202. The positioning ring 203 drives the motor shaft 106 to rotate. The motor shaft 106 drives the support plate 210 to rotate. The direction of rotation driven by the positioning ring 203 is opposite to the direction of rotation of the wiping plate 207, thereby improving the wiping effect on the surface of the motor shaft 106.

Drive the two groups of adjustment blocks 2 108 to slide on the adjustment block 107, and the adjustment block 2 108 drives the roller 109 to move and change the position of the roller 109, so that the roller 109 supports the motor shaft 106 at the bottom of the motor shaft 106. When the motor shaft 106 is aligned with the positioning frame 110 and the positioning frame 2 118, it is also placed Placed on the support plate 120, the motor shaft 106 presses the support plate 120, and the support plate 120 compresses the spring 121, driving the support frame 119 to slide on the base 2 103, changing the position of the support frame 119, ensuring the support effect of the support plate 120 on the motor shaft 106, and preventing the motor shaft 106 from falling off during the rotation. After the placement of the motor shaft 106 is completed, the transfer plate 104, the transfer frame 105 and the clamping plate 116 are driven to reset, and the clamping of the motor shaft 106 is released. Then, the positioning frame 110 and the positioning frame 2 118 are driven to slide on the base 2 103, and the positioning frame 2 118 and the positioning frame 1 110 respectively push the two ends of the motor shaft 106 to complete the adjustment of the position of the motor shaft 106.

[0036] After the motor shaft 106 is placed, the motor shaft 106 is inspected, and the inspection frame 102 is driven to slide on the base 101. The inspection frame 102 drives the multiple groups of adjustment blocks 3 117 to move to the upper end of the motor shaft 106, and drives the inspection head 112 to slide in the adjustment block 3 117. The inspection head 112 gradually approaches the motor shaft 106, and the inspection head 112 is started to work.
