Description

Technical Field

[0001] This invention relates to the field of motor spindle testing technology, and in particular to a three-phase asynchronous motor spindle testing device. Background Technology

[0002] As a core component for transmitting torque and supporting the rotor, the surface integrity of the motor shaft directly affects the reliability and lifespan of the entire machine. Even the slightest surface defect can become a stress concentration point, accelerating fatigue propagation under high-speed motor operation and cyclic loads, ultimately leading to shaft breakage or deformation, causing catastrophic equipment failures, unplanned downtime, or even safety accidents. Simultaneously, surface roughness or geometric anomalies can interfere with bearing fit precision, exacerbate vibration and noise, accelerate bearing wear, and reduce energy efficiency. Rigorous surface defect detection is not only a key quality control step to ensure long-term stable operation of the motor and meet its design life, but also a necessary measure to prevent potential failures, reduce maintenance costs, and ensure user safety and brand reputation.

[0003] Spline grooves are the core meshing structure that enables precise torque transmission between the motor shaft and transmission components such as couplings and gears. Wear in this area under load directly disrupts this precision fit: on the one hand, it reduces torque transmission capacity, causing slippage, vibration, or abnormal noise, affecting the equipment's drive accuracy; on the other hand, it exacerbates uneven stress distribution, accelerating a vicious cycle of wear, potentially leading to catastrophic failures such as spline tooth breakage or shaft torsion deformation. Metal debris generated by wear also contaminates the lubrication system, accelerating bearing and gear wear. Regularly inspecting spline groove wear can predict the lifespan of the transmission system, prevent sudden downtime, and provide crucial information for optimizing material selection, heat treatment processes, and lubrication solutions. This is an essential measure to ensure high-reliability equipment operation and prevent major losses.

[0004] Chinese utility model patent with announcement number CN215218055U discloses an automated load break-in device for splines and spline sleeves. This device changes the manual spline setting to automatic spline setting, improving the spline assembly efficiency and automatically realizing the load break-in of splines. However, this device cannot effectively change the load on the shaft during the spline load break-in process, and it cannot simultaneously detect the splines at both ends of the shaft, reducing the detection efficiency of spline shaft wear.

Detailed Implementation

[0030] refer to Figures 1 to 13 The device for detecting the spindle of a three-phase asynchronous motor includes a detection component 1 for detecting surface defects of the motor shaft 106. The detection component 1 moves the motor shaft 106 to different working positions and wipes and protects the detection head 112 after the detection is completed. A cleaning component 2 is provided on the side of the detection component 1 to wipe the motor shaft 106. The cleaning component 2 wipes the motor shaft 106 and then places it in the detection component 1 for detection, thereby improving the detection accuracy of the motor shaft 106. A load component 3 is provided at the upper end of the detection component 1 to detect the load capacity of the motor shaft 106. The load component 3 changes the load on the motor shaft 106 during operation. After the load operation is completed, the wear of the spline groove on the motor shaft 106 is detected to determine the stability of the motor shaft 106 under load.

[0031] The detection component 1 includes a base 2 103, a transfer plate 104 slidably disposed on the side of the base 2 103, a transfer frame 105 rotatably disposed on the transfer plate 104, and two sets of clamping plates 116 slidably disposed on the transfer frame 105. When the two sets of clamping plates 116 approach each other, they clamp and fix the motor shaft 106. A positioning frame 110 and a positioning frame 118 are slidably disposed on both sides of the base 2 103, respectively. Two sets of adjusting blocks 107 are slidably disposed on the base 2 103, and two sets of adjusting blocks 108 are slidably disposed on the adjusting blocks 107. Rollers 109 are rotatably disposed on the adjusting blocks 108. The rollers 109 are connected to the motor shaft 106. When shaft 106 is engaged and drive roller 109 rotates, roller 109 drives motor shaft 106 to rotate. When positioning frame one 110 or positioning frame two 118 slides on base two 103, positioning frame one 110 and positioning frame two 118 push motor shaft 106 to move, changing the position of motor shaft 106 on the two sets of rollers 109. When driving two sets of adjusting blocks one 107 to move, adjusting block one 107 drives roller 109 to move, changing the position of roller 109, so that roller 109 can support motor shaft 106 of different specifications. A support frame 119 is slidably mounted on base two 103, and a support frame 119 is slidably mounted on the support frame 119. A support plate 120 is provided, and a spring 121 is provided between the support plate 120 and the support frame 119. When the motor shaft 106 is placed on the support plate 120, the support plate 120 is pressed and slides within the support frame 119. At the same time, the support plate 120 presses the spring 121, thus supporting the motor shaft 106 and preventing it from falling off during rotation. A set of bases 101 is provided on both sides of the base 2 103. A detection frame 102 is slidably mounted on the base 101. Two sets of adjusting blocks 117 are slidably mounted at the lower end of the detection frame 102. A certain amount of material is slidably mounted at the lower end of the adjusting blocks 117. The detection head 112 is an eddy current flaw detector probe. The detection head 112 detects defects on the surface of the motor shaft 106. The detection assembly 1 also includes two sets of cleaning boxes 111. A cleaning column 113 is slidably arranged in the cleaning box 111. A placement groove 114 is arranged in the cleaning column 113. The detection head 112 is inserted into the placement groove 114. Two sets of wiping rods 115 are slidably arranged on the upper end of the cleaning column 113. The wiping rods 115 wipe the surface of the detection head 112. After the detection head 112 completes the detection of the motor shaft 106, the detection head 112 is placed in the placement groove 114 to ensure the cleanliness of the detection head 112.

[0032] The cleaning component 2 includes a base 3 201, on which a positioning frame 3 202 and a cleaning frame 204 are slidably mounted. A positioning ring 203 is coaxially rotatably mounted on the positioning frame 3 202. Multiple sets of clamping rings 209 are slidably mounted inside the positioning ring 203. When the multiple sets of clamping rings 209 approach each other, they clamp one end of the motor shaft 106. Two sets of wiping plates 207 are slidably mounted inside the cleaning frame 204. Multiple sets of wiping heads 208 are slidably mounted on the wiping plates 207. When the wiping plates 207 are driven to rotate on the cleaning frame 204, the wiping plates 207 drive the wiping heads 208 to rotate. When the wiping heads 208 are driven to slide on the wiping plates 207, the wiping heads 208 gradually approach the motor shaft 106. A wiping cloth is mounted on the end of the wiping heads 208 facing the motor shaft 106. Wiping head 208 wipes the motor shaft 106. Since different parts of the motor shaft 106 have different diameters, adjusting the position of wiping head 208 on wiping plate 207 allows for wiping of the entire motor shaft 106, improving wiping efficiency. A fixing plate 205 is slidably mounted on the cleaning frame 204, and a support plate 210 is coaxially rotatable on the fixing plate 205. The support plate 210 is in contact with the other end of the motor shaft 106, driving the cleaning frame 204 to move on the base 2. When sliding on 01, the cleaning frame 204 drives the fixing plate 205 and the support plate 210 to fit against the motor shaft 106. Then, the cleaning frame 204 continues to be driven. Since the support plate 210 is in contact with the motor shaft 106, the fixing plate 205 does not move, but the cleaning frame 204 continues to move. The second spring 206 is pressed to ensure that the support plate 210 is in close contact with the motor shaft 106. The cleaning frame 204 drives the wiping head 208 to slide on the base 201 to complete the wiping of the motor shaft 106.

[0033] Load assembly 3 includes a detection frame 301 mounted on top of base 101. An adjusting block 303 and a load frame 305 are slidably mounted on the detection frame 301. A connecting shaft 304 is rotatably mounted within the adjusting block 303, and one end of the connecting shaft 304 is connected to the motor shaft 106 via a splined shaft. A receiving disk 306 is rotatably mounted within the load frame 305, and the other end of the receiving disk 306 is connected to the motor shaft 106 via a splined shaft. A magnetic powder brake is installed within the load frame 305, which restricts the rotation of the receiving disk 306. The magnetic powder brake changes the torque experienced by the motor shaft 106 at the receiving disk 306 position when it rotates by restricting the rotation of the receiving disk 306. An adjusting block 308 is also slidably mounted on the upper end of the detection frame 301, and two sets of wiping heads 310 are slidably mounted within the adjusting block 308 for wiping... The first two parts 310 wipe the surface of the motor shaft 106. A set of mounting frames 302 are rotatably mounted on both sides of the second testing frame 301. A bonding frame 307 is slidably mounted on the mounting frame 302. The bonding frame 307 is driven by a hydraulic cylinder and has multiple sets of friction rollers 309 rotatably mounted on it. When the bonding frame 307 slides on the mounting frame 302, it drives the friction rollers 309 to bond with the motor shaft 106. By changing the pressure of the hydraulic cylinder on the bonding frame 307, the pressing force of the friction rollers 309 on the motor shaft 106 is changed. The friction rollers 309 and the magnetic powder brake on the load frame 305 synchronously adjust the load on the motor shaft 106. Multiple cameras are mounted at the lower end of the second testing frame 301. The cameras detect the wear degree of the spline groove on the motor shaft 106 through visual analysis of photographs.

[0034] Working principle: During operation, the motor shaft 106 is placed between two sets of clamping plates 116. The two sets of clamping plates 116 are driven to move closer together to clamp the motor shaft 106. The transfer frame 105 is driven to rotate on the transfer plate 104 to change the orientation of the motor shaft 106. When the motor shaft 106 is facing the cleaning component 2, the transfer plate 104 is driven to slide on the base 2 103. 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 3 202 and the cleaning frame 204, the positioning frame 3 202 is driven to move closer to the motor shaft 106. At the same time, multiple sets of clamping rings 209 are driven to move closer together. The clamping rings 209 clamp one end of the motor shaft 106. The cleaning frame 204 is driven to slide on the base 3 201. The cleaning frame 204 moves closer to the motor shaft 106. The cleaning frame 204 drives the fixing plate 205 and the support plate 210 to fit against 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 move. At this time, the fixing plate 205 is fixed to the motor shaft 106 and does not move. The cleaning frame 204 moves on the base 201 and the fixing plate 205. At the same time, the cleaning frame 204 compresses the spring 206. While the cleaning frame 204 moves, it drives multiple sets of wiping heads 208 to approach the motor shaft 106. The wiping heads 208 contact the surface of the motor shaft 106 and wipe the motor shaft 106. When the wiping plate 207 slides on the cleaning frame 204, it drives multiple sets of wiping heads 208 to move. At the same time, it drives the positioning ring 203 to rotate on the positioning frame 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 of the motor shaft 106 driven by the positioning ring 203 is opposite to the direction of rotation of the wiping plate 207, which improves the wiping effect on the surface of the motor shaft 106.

[0035] After wiping the motor shaft 106, the drive transfer plate 104, transfer frame 105, and clamping plate 116 clamp the motor shaft 106, transferring it to the position of the detection component 1. When the motor shaft 106 is aligned with the positioning frame 110 and the positioning frame 218, the drive moves the two sets of adjusting blocks 107 on the base 2 103. The adjusting blocks 107 drive the adjusting blocks 2108 to move, and the two sets of adjusting blocks 2108 slide on the adjusting blocks 107. The adjusting blocks 2108 drive the rollers 109 to move, changing the position of the rollers 109 so that the rollers 109 support the motor shaft 106 at the bottom. When the motor shaft 106 is aligned with the positioning frame 110 and the positioning frame 218, it is also released. The motor shaft 106 is placed on the support plate 120. The motor shaft 106 presses against the support plate 120, and the support plate 120 compresses the spring 121. The drive support frame 119 slides on the base 103, changing the position of the support frame 119 to ensure the support effect of the support plate 120 on the motor shaft 106 and prevent the motor shaft 106 from falling off during rotation. After the placement of the motor shaft 106 is completed, the drive transfer plate 104, transfer frame 105 and clamping plate 116 are reset to release the clamping of the motor shaft 106. Then the drive positioning frame 110 and positioning frame 118 slide on the base 103. The positioning frame 118 and positioning frame 110 respectively push the two ends of the motor shaft 106 to move, completing the adjustment of the position of the motor shaft 106.

[0036] After placing the motor shaft 106, it is inspected. The drive inspection frame 102 slides on the base 101, moving multiple sets of adjusting blocks 117 to the upper end of the motor shaft 106. The drive inspection head 112 slides within the adjusting blocks 117, gradually approaching the motor shaft 106. The inspection head 112 is then activated, simultaneously driving the adjusting blocks 117 to slide on the inspection frame 102 and rotating multiple sets of rollers 109. The rollers 109 rotate the motor shaft 106, and the inspection head 112 inspects for defects on the surface of the motor shaft 106. After inspection, the drive inspection frame 102... 02. The detection head 112 and the adjusting block 3 117 are reset. The detection frame 102 moves the adjusting block 3 117 and the detection head 112 to the top of the cleaning box 111. The cleaning column 113 is driven to slide inside the cleaning box 111. The cleaning column 113 drives the placement groove 114 and the wiping rod 115 to rise. At this time, the detection head 112 is inserted into the cleaning column 113. The placement groove 114 protects the detection head 112 to prevent it from being contaminated. At the same time, the wiping rod 115 is driven to rotate on the cleaning column 113. The wiping rod 115 wipes the surface of the detection head 112 to ensure the accuracy of the detection head 112 in detecting the motor shaft 106.

[0037] After inspecting the defects on the surface of the motor shaft 106, the drive transfer plate 104, transfer frame 105, and clamping plate 116 transfer the motor shaft 106. When the motor shaft 106 is aligned with the load frame 305 and receiving plate 306, the drive load frame 305 and adjusting block 303 slide on the inspection frame 301. Both ends of the motor shaft 106 are inserted into the connecting shaft 304 and receiving plate 306 respectively, completing the fixation of the motor shaft 106. The drive transfer plate 104, transfer frame 105, and clamping plate 116 are then reset, and the drive connecting shaft 304 is adjusted... When the fourth section 303 rotates, the fourth section 303 drives the motor shaft 106 to rotate, and the motor shaft 106 drives the receiving disk 306 to rotate. The load frame 305 brakes the receiving disk 306 through the magnetic powder brake, changing the load on the motor shaft 106 when it rotates. At the same time, it drives the two sets of mounting frames 302 to rotate on the second detection frame 301. The mounting frame 302 drives the bonding frame 307 to align with the motor shaft 106, and drives the bonding frame 307 to slide on the mounting frame 302. The bonding frame 307 drives multiple sets of friction rollers 309 to bond with the motor shaft 106. The bonding frame 307 is driven by a hydraulic cylinder. By changing the pressure applied to the bonding frame 307 by the hydraulic cylinder, the pressure of the friction roller 309 on the motor shaft 106 is changed. The friction roller 309 and the receiving plate 306 synchronously apply a load to the motor shaft 106. During the detection of the motor shaft 106, the driving adjustment block 308 slides on the detection frame 301. The adjustment block 308 drives the wiping head 310 to move, and drives the wiping head 310 to slide within the adjustment block 308. The wiping head 310 is in contact with the motor shaft 106. The surface of the motor shaft 106 is wiped to improve the pressing and friction effect between the friction roller 309 and the surface of the motor shaft 106. After the load operation is completed, the drive transfer plate 104, transfer frame 105 and clamping plate 116 clamp the motor shaft 106. Then the drive adjustment block 303 and load frame 305 are reset to expose the spline groove position on the motor shaft 106. At this time, the camera set at the lower end of the detection frame 301 is activated. The camera takes pictures of the spline groove position and identifies the wear status of the spline groove on the motor shaft 106 under load.
