Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically a device for detecting the coaxiality of motor shafts. Background Technology

[0002] The coaxiality of a motor shaft refers to the consistency or matching degree between the geometric center of the motor shaft and its axis of rotation. Simply put, it is whether the center of the shaft is always aligned with the axis of rotation during the rotation process, and whether there is any deviation or misalignment. The coaxiality of the motor shaft is an important parameter for measuring the performance and operational stability of a motor.

[0003] Traditional methods for testing the coaxiality of motor shafts typically rely on manual operation or simple measuring tools, which have drawbacks such as low accuracy, low efficiency, and susceptibility to subjective factors of operators. Most existing testing devices cannot meet the need for rapid and efficient testing of the coaxiality of the same motor shaft at different positions. Furthermore, existing devices cannot perform batch testing of motor shafts of the same model with high accuracy and high efficiency.

[0004] To address this issue, we provide a motor shaft coaxiality detection device. Utility Model Content

The top end of the fixing ring 6 is fixedly connected to the bottom surface of the support plate 212. The fixing ring 6 can be used to reinforce the infrared ranging sensor 214 and prevent the infrared ranging sensor 214 from falling off during use.

[0029] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 The outer surface of the first bearing 206 is fixedly connected to the inner wall of the second fixed seat 207. The outer surface of the controller 208 is fixedly connected to the fixed frame 3. The bottom surface of the fixed frame 3 is fixedly connected to the upper surface of the connecting plate 1. The controller 208 is electrically connected to the drive motor 202, the servo motor 215 and the infrared ranging sensor 214 through wires respectively. The fixed frame 3 can be used to reinforce the controller 208 and prevent the controller 208 from shaking during use, which would affect the stability of the circuit. The controller 208 is a master command device that controls the starting, speed regulation, braking and reversing of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to a predetermined sequence. It consists of a program counter, an instruction register, an instruction decoder, a timing generator and an operation controller 208. It is the "decision-making body" that issues commands, that is, it completes the coordination and command of the operation of the entire computer system.

[0030] Working principle: In use, first connect the controller 208, drive motor 202, servo motor 215, and infrared ranging sensor 214 to the power supply. When using the device, the operator engages the left end of the motor shaft body 204 to be measured inside the clamping sleeve 209. Then, the right end of the motor shaft body 204 and the output end of the drive motor 202 are engaged inside the coupling 203. The operator then uses the controller 208 to control the drive motor 202. Supported by the first fixed seat 201, the drive motor 202 drives the coupling 203 to rotate. The rotation of the coupling 203 drives the motor shaft body 204 to rotate. The motor shaft body 204 is then engaged in the clamping sleeve 209. Supported by the first bearing 206 and the second fixed seat 207, the motor shaft body 204 rotates stably. The controller 208 controls the servo motor 215 to operate. Supported by the moving seat 205, the servo motor 215 drives the lead screw 211 to rotate on the inner wall of the slide groove 210. The lead screw 211 is threadedly connected to the slider 213. The rotation of the lead screw 211, in turn, causes the slider 213, the support plate 212, and the infrared ranging sensor 214 to slide left and right along the inside of the slide groove 210, i.e., along the top of the motor shaft body 204. The operator can move the infrared ranging sensor 214 to different positions according to the measurement needs. Then, the controller 208... The controller 208 controls the infrared ranging sensor 214 to operate. The infrared emitter within the infrared ranging sensor 214 continuously emits infrared signals towards the surface of the motor shaft body 204. These infrared signals are reflected from the surface of the motor shaft body 204, and the reflected infrared signals are received by the infrared receiver within the infrared ranging sensor 214. This achieves stable measurement of the distance between the infrared ranging sensor 214 and the surface of the motor shaft body 204, specifically the radial distance between the motor shaft body 204 and the infrared ranging sensor 214. If the coaxiality of the motor shaft body 204 changes during rotation, the infrared sensor will detect this error. The distance measured by the ranging sensor 214 will also change, and the measured data will be transmitted to the controller 208. This data is compared with the standard value set in the controller 208. When there is an error between the data and the value set in the controller 208, the warning light set in the controller 208 will sound an alarm. The staff uses the controller 208 to control the drive motor 202 to stop working. A problem with the coaxiality of the motor shaft body 204 is detected. This device can accurately measure the coaxiality of the motor shaft body 204 at different positions, and can quickly achieve the purpose of rapid testing of batches of motor shaft bodies 204, thereby improving the efficiency of motor shaft body 204 measurement.
