[0002] The clearance detection device for bearings usually consists of clearance detection equipment, positioning equipment, adjustment equipment and protection equipment.

[0003] The patent with patent announcement number CN209910539U involves a micropore detection device and its use method. In order to solve the current complex problems of micropore detection, the patent provides a simple and easy three-dimensional spatial angle detection structure device. The technical solution provided by the patent is as follows: the detection device of the patent includes a detection body and a needle gauge used in conjunction with the detection body, the detection body is provided with a cavity, the top of the detection body is provided with a detection groove, and the outer wall of the detection body is provided with a reference groove. The beneficial effect of the patent is that the micropore angle gauge provided by the patent completes the detection of the size and angle of the three-dimensional micropore, and can effectively check the size and angle accuracy of the three-dimensional small hole of the object to be detected. The angle of similar spatial micropores can be detected by this patent.

[0004] In the above patent, the three-dimensional micropore size and angle detection is completed by providing a micropore angle gauge, which can effectively check the size and angle accuracy of the three-dimensional small holes of the inspected object. However, it is difficult to automatically correct the position of the workpiece to be inspected. If the workpiece position is not correctly corrected, the clearance detection equipment will have measurement errors or angle errors, which will affect the subsequent judgment of the workpiece quality, making it difficult to unify the product clearance standards, and thus leading to a decrease in the workpiece qualification rate.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a clearance detection device based on bearing production, comprising a detection frame and a correction component, a U-shaped frame is fixedly installed on the surface of the detection frame, a servo motor is fixedly installed on the front side of the U-shaped frame, a screw rod 1 is fixedly installed on the output end of the servo motor, a moving block is slidably installed on the top of the inner wall of the U-shaped frame, the moving block is threadedly connected to the screw rod 1, and a clearance detection device is fixedly installed on the bottom of the moving block, a square groove is opened on the top of the detection frame, a rectangular plate is fixedly installed on the top of the detection frame, a motor is fixedly installed on the right side of the rectangular plate, a screw rod 2 is fixedly installed on the output end of the motor, a moving frame is slidably installed on the bottom of the inner wall of the square groove, the moving frame is threadedly connected to the screw rod 2, a T-shaped rod is slidably penetrated on the front side of the moving frame, a correction plate is fixedly installed on the rear side of the T-shaped rod, and a detection plate is fixedly installed on the inner wall of the U-shaped frame, the correction plate moves in the direction close to the U-shaped rod under the reaction force of the extruded workpiece, and the correction plate moves in the direction close to the U-shaped rod to drive the T-shaped rod to move.

[0007] According to the above technical solution, a No. 1 spring is arranged between the T-shaped rod and the movable frame, and the No. 1 spring can drive the T-shaped rod to reset. A U-shaped rod is fixedly installed on the right side of the movable frame, and an arc panel is fixedly installed on the inner wall of the movable frame. The arc panel slowly deforms so that the correction plate can only move slowly to correct the position of the workpiece.

[0008] According to the above technical solution, a detection groove is opened on the top of the detection plate, and the workpiece can be initially limited by the detection groove. The arc panel is elastic. The first screw rod passes through the inner and outer walls of the U-shaped frame, and the second screw rod passes through the inner and outer walls of the movable frame. There are two sets of T-shaped rods, correction plates and arc panels.

[0009] According to the above technical solution, a collecting component for cleaning waste chips is provided on the top of the detection plate, and a limiting component is provided on the inner wall of the U-shaped frame. The collecting component includes a cleaning hole, a cleaning rod, a cleaning plate, an inclined plate, a stabilizing plate and a collecting groove. The cleaning plate moves in a direction away from the rectangular plate to drive the inclined plate to move, and the inclined plate moves to scrape off the magnetic waste chips remaining on the top of the workpiece. The cleaning hole is opened at the top of the detection plate, the cleaning rod is fixedly installed on the inner wall of the cleaning hole, the cleaning plate is slidably installed on the circumferential surface of the cleaning rod, the inclined plate is fixedly installed on the rear side of the cleaning plate, the stabilizing plate is fixedly installed on the circumferential surface of the cleaning rod, and the collecting groove is opened at the top of the detection plate.

[0010] According to the above technical solution, a No. 2 spring is arranged between the cleaning plate and the stabilizing plate, and the No. 2 spring can drive the cleaning plate to reset. A V-shaped magnet is fixedly installed on the inner wall of the collecting trough, and the right side of the stabilizing plate is set as an arc surface. The stabilizing plate vibrates when hit by the cleaning plate, and the vibration of the cleaning plate drives the vibration of the inclined plate, and the vibration of the inclined plate shakes off the magnetic waste chips at the bottom.

[0011] According to the above technical solution, the left side of the cleaning plate is set as an arc surface, and the inclined plate is elastic. The elasticity of the inclined plate can prevent the inclined plate from being stuck on the left side of the workpiece, and the cleaning plate is in contact with the U-shaped rod.

[0012] According to the above technical scheme, the limit assembly includes a linkage plate, a connecting tube, a linkage frame, a hollow plate, a limit frame and a limit gear. The limit gear is limited by the limit frame so that the screw rod cannot continue to rotate. The linkage plate is fixedly installed on the inner wall of the U-shaped frame, the connecting tube is fixedly passed through the upper and lower walls of the linkage plate, the linkage frame is slidably installed on the inner wall of the connecting tube, the hollow plate is fixedly installed on the inner wall of the connecting tube, the limit frame is slidably installed on the inner wall of the connecting tube, and the limit gear is fixedly installed on the second circumferential surface of the screw rod.

[0013] According to the above technical solution, a reset spring is arranged between the linkage frame and the hollow plate, and the hollow plate can be reset by the reset spring. A filler is arranged inside the connecting pipe, and the top of the limit frame is arranged as an inclined surface.

[0014] A method for using a clearance detection device for bearing production, using the above-mentioned clearance detection device for bearing production, comprising the following steps: Step 1: Place the workpiece to be inspected at the bottom of the inner wall of the inspection tank. After the workpiece is firmly placed, the motor drives the second screw to rotate, and the second screw drives the moving frame to move toward the workpiece. The moving frame moves toward the workpiece and drives the T-shaped rod to move; Step 2: The T-shaped rod moves toward the direction close to the workpiece, driving the correction plate to move. The correction plate moves to contact with the workpiece to be inspected and squeezes the workpiece to be inspected. The correction plate is subjected to the reaction force of the squeezed workpiece and moves toward the direction close to the U-shaped rod. The correction plate moves toward the direction close to the U-shaped rod, driving the T-shaped rod to move. Step 3: The correction plate cooperates with the elastic force of spring No. 1 to correct the position of the workpiece. After the workpiece position is corrected, the servo motor drives the screw rod 1 to rotate, and the rotation of the screw rod 1 drives the moving block to move away from the servo motor; Step 4: The moving block moves away from the servo motor to drive the clearance detection device to move. When the clearance detection device moves to a suitable position angle, the servo motor stops working, and the clearance detection device performs clearance detection on the workpiece at the same time.

[0015] The present invention provides a clearance detection device for bearing production, which has the following beneficial effects: (1) The invention corrects the position of the workpiece by means of a correction plate in cooperation with the elastic force of a No. 1 spring. By automatically correcting the position of the workpiece, the position of the workpiece can be ensured to be accurate during the detection process, thereby avoiding measurement errors caused by workpiece position deviations, thereby improving the accuracy and stability of detection. The arc plate is slowly deformed so that the correction plate can only move slowly to correct the position of the workpiece. The slow movement of the correction plate can effectively avoid over-positioning or position errors of the workpiece caused by the impact of too fast movement, thereby further ensuring the accuracy of workpiece positioning.

[0016] (2) In the present invention, the cleaning plate moves in a direction away from the rectangular plate to drive the inclined plate to move. The inclined plate moves to scrape off the magnetic waste chips remaining on the top of the workpiece. The magnetic waste chips remaining on the top of the workpiece will cause errors in the detection results and affect the accurate measurement of the bearing clearance. The magnetic impurities attached to the surface of the workpiece can be effectively removed by scraping off the magnetic waste chips by the inclined plate, thereby avoiding the interference of the impurities on the clearance detection equipment, thereby improving the accuracy of the clearance detection.

[0017] (3) This invention uses the vibration of the inclined plate to shake off the magnetic waste at the bottom. The shaken magnetic waste is adsorbed on the surface of the V-shaped magnet under the magnetic force of the V-shaped magnet itself and collected. The adsorption of the V-shaped magnet can prevent the waste from scattering, thereby avoiding secondary contamination of the detection process or equipment by the waste, further ensuring the accuracy of the measurement. At the same time, the design of the V-shaped magnet can make the magnetic waste concentrate on the surface of the magnet, which is convenient for subsequent cleaning.

[0018] (4) In the present invention, the limit gear is limited by the limit frame so that the screw rod 1 cannot continue to rotate. The screw rod 1 cannot continue to rotate, thereby ensuring the accuracy of the position and angle of the clearance detection device during the detection process. If the position and angle of the clearance detection device are inaccurate, it will cause errors in the clearance measurement. By ensuring the detection angle and position of the clearance detection device, errors caused by angle or position deviations can be avoided. In addition, the limitation of the limit frame can prevent the angle of the clearance detection device from changing due to accidental contact by external force, thereby further improving the accuracy of the measurement results.

A U-shaped rod 18 is fixedly installed on the right side of the moving frame 11, and an arc panel 14 is fixedly installed on the inner wall of the moving frame 11. The arc panel 14 slowly deforms so that the correction plate 13 can only move slowly to correct the position of the workpiece. The slow movement of the correction plate 13 can effectively avoid over-positioning or position error of the workpiece caused by the impact of too fast movement, thereby further ensuring the accuracy of the workpiece positioning.

[0024] A detection groove is provided on the top of the detection plate 15, through which the workpiece can be initially limited. The arc panel 14 is elastic, the screw rod 1 4 passes through the inner and outer walls of the U-shaped frame 2, and the screw rod 2 10 passes through the inner and outer walls of the moving frame 11. There are two sets of T-shaped rods 12, correction plates 13 and arc panels 14.

[0025] A method for using a clearance detection device for bearing production, using the above-mentioned clearance detection device for bearing production, comprising the following steps: Step 1: Place the workpiece to be inspected at the bottom of the inner wall of the inspection tank. After the workpiece is firmly placed, the motor 9 drives the screw rod 10 to rotate, and the screw rod 10 drives the moving frame 11 to move toward the workpiece. The moving frame 11 moves toward the workpiece and drives the T-shaped rod 12 to move. Step 2: The T-shaped rod 12 moves toward the direction close to the workpiece, driving the correction plate 13 to move. The correction plate 13 moves to contact the workpiece to be inspected and squeezes the workpiece to be inspected. The correction plate 13 is subjected to the reaction force of the squeezed workpiece and moves toward the direction close to the U-shaped rod 18. The correction plate 13 moves toward the direction close to the U-shaped rod 18 and drives the T-shaped rod 12 to move. Step 3: The correction plate 13 cooperates with the elastic force of the No. 1 spring to correct the position of the workpiece. After the workpiece position is corrected, the servo motor 3 drives the screw rod 4 to rotate, and the rotation of the screw rod 4 drives the moving block 5 to move away from the servo motor 3; Step 4: The moving block 5 moves away from the servo motor 3 to drive the clearance detection device 6 to move. When the clearance detection device 6 moves to a suitable position angle, the servo motor 3 stops working, and the clearance detection device 6 performs clearance detection on the workpiece.

[0026] When this embodiment is working: the workpiece to be inspected is placed at the bottom of the inner wall of the inspection groove. After the workpiece is firmly placed, the motor 9 is operated to drive the screw rod 10 to rotate. The screw rod 10 drives the moving frame 11 to move in the direction close to the workpiece. The moving frame 11 moves in the direction close to the workpiece and drives the T-shaped rod 12 to move. The T-shaped rod 12 moves in the direction close to the workpiece and drives the correction plate 13 to move. The correction plate 13 moves and contacts the workpiece to be inspected and squeezes the workpiece to be inspected. The correction plate 13 is subjected to the reaction force of the squeezed workpiece and moves in the direction close to the U-shaped rod 18. The correction plate 13 moves in the direction close to the U-shaped rod 18 and drives the T-shaped rod 12 to move. The T-shaped rod 12 moves to pull the No. 1 spring. The No. 1 spring is pulled by the T-shaped rod 12 and deforms and Force is accumulated, and the correction plate 13 cooperates with the elastic force of spring No. 1 to correct the position of the workpiece. At the same time, the correction plate 13 moves to contact the arc panel 14 and squeezes the arc panel 14. The arc panel 14 is squeezed by the correction plate 13 and can only deform slowly. The arc panel 14 slowly deforms so that the correction plate 13 can only move slowly to correct the position of the workpiece. After the workpiece position is corrected, the servo motor 3 operates to drive the screw rod 4 to rotate. The rotation of the screw rod 4 drives the moving block 5 to move away from the servo motor 3. The moving block 5 moves away from the servo motor 3 and drives the clearance detection device 6 to move. When the clearance detection device 6 moves to a suitable position angle, the servo motor 3 stops operating, and the clearance detection device 6 performs clearance detection on the workpiece.

The magnetic waste chips are scraped off by moving the inclined plate 164, so that the magnetic impurities attached to the surface of the workpiece can be effectively removed, thereby avoiding the interference of the impurities with the clearance detection device 6, thereby improving the accuracy of the clearance detection.

[0028] A No. 2 spring is arranged between the cleaning plate 163 and the stabilizing plate 165, and the No. 2 spring can drive the cleaning plate 163 to reset. A V-shaped magnet 167 is fixedly installed on the inner wall of the collecting groove 166. The right side of the stabilizing plate 165 is arranged as an arc surface. The stabilizing plate 165 vibrates when hit by the cleaning plate 163. The vibration of the cleaning plate 163 drives the inclined plate 164 to vibrate. The vibration of the inclined plate 164 shakes off the magnetic waste chips at the bottom. The adsorption of the V-shaped magnet 167 can prevent the waste chips from scattering, thereby avoiding the secondary contamination of the detection process or equipment by the waste chips, and further ensuring the accuracy of the measurement.

[0029] The left side of the cleaning plate 163 is set as an arc surface, and the inclined plate 164 is elastic. The elasticity of the inclined plate 164 can prevent the inclined plate 164 from being stuck on the left side of the workpiece, and the cleaning plate 163 is in contact with the U-shaped rod 18.

[0030] The limiting assembly includes a linkage plate 171, a connecting tube 172, a linkage frame 173, a hollow plate 174, a limiting frame 176 and a limiting gear 177.

By ensuring the detection angle and position of the clearance detection device 6, errors caused by angle or position deviations can be avoided.

[0031] A reset spring 175 is arranged between the linkage frame 173 and the hollow plate 174, and the reset spring 175 can drive the hollow plate 174 to reset. A filler is arranged inside the connecting tube 172, and the top of the limit frame 176 is arranged as an inclined surface. The limit of the limit frame 176 can prevent the external force from accidentally touching and causing the angle of the clearance detection device 6 to change, thereby further improving the accuracy of the measurement result.

[0032] When the present embodiment is working, the moving frame 11 moves toward the direction close to the workpiece, driving the U-shaped rod 18 to move. The U-shaped rod 18 moves toward the direction close to the workpiece, contacts the cleaning plate 163 and squeezes the cleaning plate 163. The cleaning plate 163 is squeezed by the U-shaped rod 18 and moves in the direction away from the rectangular plate 8. The cleaning plate 163 moves in the direction away from the rectangular plate 8 to squeeze the No. 2 spring. The No. 2 spring is squeezed by the cleaning plate 163 to deform and accumulate force. At the same time, the cleaning plate 163 moves in the direction away from the rectangular plate 8, driving the inclined plate 164 to move. The inclined plate 164 moves to scrape off the magnetic waste chips remaining on the top of the workpiece. At the same time, the cleaning plate 163 moves in the direction away from the rectangular plate 8, contacts the arc surface of the stabilizing plate 165 and stabilizes it. The plate 165 impacts, and the stabilizing plate 165 is vibrated by the impact of the cleaning plate 163. The vibration of the cleaning plate 163 drives the inclined plate 164 to vibrate. The vibration of the inclined plate 164 shakes off the magnetic waste at the bottom. The vibrated magnetic waste is adsorbed on the surface of the V-shaped magnet 167 under the magnetic force of the V-shaped magnet 167 itself and collected. When the U-shaped rod 18 moves toward the direction close to the rectangular plate 8 to reset, the U-shaped rod 18 moves toward the direction close to the rectangular plate 8 to break away from the contact with the cleaning plate 163. The cleaning plate 163 breaks away from the contact with the U-shaped rod 18, so that the cleaning plate 163 moves toward the direction close to the rectangular plate 8 to reset under the elastic force of the No. 2 spring. The cleaning plate 163 moves toward the direction close to the rectangular plate 8 to drive the inclined plate 164 to move and reset.

[0033] The cleaning plate 163 moves in a direction away from the rectangular plate 8 so that its arc surface contacts the linkage frame 173 and squeezes the linkage frame 173. The linkage frame 173 is squeezed by the cleaning plate 163 and moves in a direction away from the rectangular plate 8. The linkage frame 173 moves in a direction away from the rectangular plate 8 to squeeze the return spring 175.
