A placement seat 12 is installed on the base 2, and a rod groove 13 is opened at the center of the placement seat 12. A rotating rod 7 runs through the rod groove 13, and a shaft sleeve 29 is placed on the placement seat 12. When working, the existing detection device usually uses a vernier caliper to measure the inner diameter of the shaft sleeve 29 to check whether the shaft sleeve 29 is qualified during the detection of the inner diameter of the front installation shaft sleeve 29. The detection speed is slow, resulting in low detection efficiency. The shaft sleeve 29 is clamped and fixed by the first clamping plate 19 and the second clamping plate 20. The shaft sleeve 29 is fixed so that it is quickly fixed to the center of the placement seat 12. At this time, the inner wall of the shaft sleeve 29 is opposite to the infrared rangefinder 9. The infrared generator 10 in the infrared rangefinder 9 emits an infrared beam. The infrared beam is reflected after encountering the inner wall of the shaft sleeve 29. The reflected infrared beam is received by the infrared receiver 11. The infrared receiver 11 converts the optical signal into an electrical signal and sends the electrical signal to the control panel 28. The control panel 28 obtains the time difference between the infrared beam being reflected and being received, and calculates the distance between the infrared rangefinder 9 and the inner wall of the shaft sleeve 29 according to the propagation speed of the infrared beam in the air, and adds the radius value of the rotating rod 7. , which is the radius value of the inner diameter of the sleeve 29. The control panel 28 controls the operation of the first motor 6. The first motor 6 drives the rotating rod 7 to rotate 360 ​​degrees. The infrared rangefinder 9 measures the inner diameter of the sleeve 29 for one circle. The control panel 28 can quickly obtain a group of radius values ​​of the inner diameter of the sleeve 29.

[0019] See also Figure 3-4As shown, two groups of slide grooves 14 are provided in the placement seat 12, and a guide rod 15 is fixedly installed on the inner wall of one group of slide grooves 14, and a screw rod 16 is rotatably installed on the inner wall of the other group of slide grooves 14. The thread directions on the screw rod 16 are symmetrically opposite. A second motor 17 is installed on the side wall of the placement seat 12 through the machine base. The output shaft of the second motor 17 is fixedly connected to one end of the screw rod 16. The second motor 17 is connected to the control panel 28 through an internal circuit. Two groups of sliders 18 are symmetrically assembled in the slide groove 14. The sliders 18 slide in cooperation with the screw rod 16 through threads.

A spring 25 is installed between the side wall of the movable plate 23 and the inner wall of the plate slot 22. A first electrode sheet 26 is installed on the side wall of the movable plate 23. A second electrode sheet 27 is installed on the inner wall of the plate slot 22. The first electrode sheet 26 and the second electrode sheet 27 are connected to the indicator light 21 through an internal circuit. During operation, the clamp in the existing detection device cannot control the clamping force of the clamp in the process of clamping and fixing the shaft sleeve 29. The clamp is prone to excessive clamping force, causing damage to the shaft sleeve 29, resulting in damage to the shaft sleeve 29. The protection is poor, and the shaft sleeve 29 is placed on the placement seat 12. The control panel 28 controls the operation of the second motor 17 to drive the screw rod 16 to rotate, and the screw rod 16 drives the two sets of sliders 18 thereon to move synchronously relative to each other. The two sets of sliders 18 drive the first clamping plate 19 and the second clamping plate 20 to move synchronously relative to each other. During the placement process, the shaft sleeve 29 is placed close to the first clamping plate 19, so that the first clamping plate 19 first contacts with the shaft sleeve 29 and pushes the shaft sleeve 29 to move toward the center of the placement seat 12. The moving rod 24 on the second clamping plate 20 will first contact the outer wall of the shaft sleeve 29, and the moving rod 24 is pushed into the plate groove 22. The moving rod 24 drives the moving plate 23 to move horizontally, and the moving plate 23 drives the first electrode The plate 26 moves horizontally, and at the moment when the second splint 20 is in contact with the outer wall of the sleeve 29, the moving rod 24 is completely pushed into the plate groove 22. At this time, the first electrode plate 26 is in contact with the second electrode plate 27, and the internal circuit of the indicator light 21 is connected. The indicator light 21 sends an electrical signal to the control panel 28. After receiving the electrical signal, the control panel 28 controls the second motor 17 to stop operating, thereby achieving the clamping and fixation of the sleeve 29 and the rapid positioning of the sleeve 29, so that the sleeve 29 is quickly positioned at the center of the placement seat 12, and the clamping force of the first splint 19 and the second splint 20 is moderate, which avoids damage to the sleeve 29 due to excessive clamping force, and is beneficial to improving the protection of the sleeve 29.

[0020] Working principle: The clamp in the existing detection device cannot control the clamping force of the clamp during the process of clamping and fixing the sleeve 29. The clamp is prone to excessive clamping force, causing damage to the sleeve 29, resulting in poor protection for the sleeve 29. The sleeve 29 is placed on the placement seat 12, and the control panel 28 controls the operation of the second motor 17 to drive the screw rod 16 to rotate. The screw rod 16 drives the two sets of sliders 18 thereon to move synchronously relative to each other. The two sets of sliders 18 drive the first clamping plate 19 and the second clamping plate 20 to move synchronously relative to each other. During the placement process, the sleeve 29 is placed close to the first clamping plate 19, so the first clamping plate 19 first contacts the sleeve 29 and pushes the sleeve 29 to move toward the center of the placement seat 12. The moving rod 24 on the second clamping plate 20 will first contact the outer wall of the sleeve 29, and the moving rod 24 is When the plate groove 22 is pushed in, the moving rod 24 drives the moving plate 23 to move horizontally, and the moving plate 23 drives the first electrode sheet 26 to move horizontally. At the moment when the second clamping plate 20 is in contact with the outer wall of the shaft sleeve 29, the moving rod 24 is completely pushed into the plate groove 22. At this time, the first electrode sheet 26 is in contact with the second electrode sheet 27, and the internal circuit of the indicator light 21 is connected. The indicator light 21 sends an electrical signal to the control panel 28. After receiving the electrical signal, the control panel 28 controls the second motor 17 to stop operating, thereby achieving the clamping and fixing of the shaft sleeve 29 and the rapid positioning of the shaft sleeve 29, so that the shaft sleeve 29 is quickly positioned to the center of the placement seat 12. The clamping force of the first clamping plate 19 and the second clamping plate 20 is moderate, which avoids damage to the shaft sleeve 29 caused by excessive clamping force, and is conducive to improving the protection of the shaft sleeve 29.In the process of detecting the inner diameter of the front-mounted shaft sleeve 29, the existing detection device usually uses a vernier caliper to measure the inner diameter of the shaft sleeve 29 to check whether the shaft sleeve 29 is qualified. The detection speed is slow, resulting in low detection efficiency. The shaft sleeve 29 is clamped and fixed by the first clamping plate 19 and the second clamping plate 20, so that the shaft sleeve 29 is quickly fixed to the center of the placement seat 12. At this time, the inner wall of the shaft sleeve 29 is opposite to the infrared rangefinder 9. The infrared generator 10 in the infrared rangefinder 9 emits an infrared light beam. The infrared light beam encounters the inner wall of the shaft sleeve 29 and is reflected. The reflected infrared light beam is received by the infrared receiver 11. The infrared receiver 11 converts the optical signal into an electrical signal and sends the electrical signal to the control panel 28. The control panel 28 obtains the time difference between the infrared light beam being reflected and being received. The distance between the infrared rangefinder 9 and the inner wall of the sleeve 29 is calculated based on the propagation speed of the infrared beam in air. This is then added to the radius of the rotating rod 7 to obtain the inner radius of the sleeve 29. The control panel 28 controls the operation of the first motor 6, which drives the rotating rod 7 to rotate 360°. The infrared rangefinder 9 measures the inner diameter of the sleeve 29 for one full rotation. The control panel 28 quickly captures a set of inner radius values ​​for the sleeve 29. If the sleeve 29 is of acceptable size, the radius values ​​for the entire group of sleeves 29 are identical. If the sleeve 29 is unqualified, the radius values ​​for the entire group of sleeves 29 differ. At this point, the control panel 28 activates the alarm light 8, indicating that the sleeve 29 is unqualified. This allows for rapid detection of the inner diameter of the sleeve 29, improving detection efficiency.
