The motor shaft is a cylindrical component that protrudes from the motor and its housing, and is usually used to connect the motor and other mechanical devices.

After the motor shaft is processed, its surface is prone to adhering to oil stains and metal debris. During detection, it is impossible to clean the oil stains and metal debris on its surface, which will affect the detection work of the motor shaft and reduce the detection accuracy; 2.

[0030] AsFigures 1 - 10 As shown in the figure, two mounting plates 12 are both fixed to the top of the detection table 11. Each mounting groove 13 is opened in the middle of the top of one mounting plate 12. Two clamps 14 are respectively fixed to one end of the two mounting plates 12 close to each other. The clamp 14 is used to fix the motor shaft, so as to prevent the motor base from moving during the detection process and affecting the detection accuracy. The clamp 14 is a prior art and will not be specifically described here.

[0031] As Figures 1 - 10 shown, the moving component includes a vertical plate 19, a first electric push rod 20 and a push plate 16. The vertical plate 19 is located on one side of a mounting plate 12 and fixed to the top of the detection table 11. The first electric push rod 20 is installed on the vertical plate 19. The push plate 16 is located on the side of the vertical plate 19 close to the mounting plate 12. The output end of the first electric push rod 20 is fixedly connected to the push plate 16. The first laser distance sensor 18 is located on one side of the detection plate 17 and fixedly installed on the top of the push plate 16. Specifically, the detection end of the first laser distance sensor 18 is flush with the side surface of the push plate 16 close to the mounting plate 12. Two side plates 21 are symmetrically fixed on both sides of the push plate 16. A first guide rod 22 is slidably provided in the middle of each side plate 21. Two connecting plates 23 are symmetrically fixed on both sides of the mounting plate 12 near the vertical plate 19. One end of each first guide rod 22 is fixedly connected to a connecting plate 23; When the length of the motor shaft needs to be detected, the two ends of the two motor shafts are placed inside the mounting grooves 13 on the tops of the two mounting plates 12, and one end of the motor shaft is made to contact the top plate 55. The two clamps 14 are used to position the motor shaft. The controller controls the first electric push rod 20 to work. The first electric push rod 20 can drive the push plate 16 to move towards the end close to the motor shaft. When the push plate 16 contacts the other end of the motor shaft, at this time, the two ends of the motor shaft are respectively in contact with the push plate 16 and the top plate 55. By using the first laser distance sensor 18 to detect the distance between the detection end of the first laser distance sensor 18 and the detection plate 17, the distance between the push plate 16 and the top plate 55 can be obtained, and thus the length of the motor shaft can be detected; When the push plate 16 moves, it can drive the two side plates 21 on both sides to move, and the first guide rod 22 can provide guidance for the side plates 21.

[0032] As Figures 1 - 10 shown, the rotating component includes a gear ring 39, a first gear 40, two fixed rings 31 and two rotating rings 32. The two fixed rings 31 are both fixed to the top of the detection table 11. The two rotating rings 32 are respectively located on one side of the two fixed rings 31 close to each other. Each rotating ring 32 is rotatably arranged on a fixed ring 31 through a bearing. The two ends of the cross plate 33 are respectively fixedly connected to the two rotating rings 32. The gear ring 39 is fixedly installed on the outer wall of one of the rotating rings 32. The first gear 40 is rotatably arranged on the detection table 11. The gear ring 39 and the first gear 40 are meshed with each other; When the first gear 40 rotates, it can drive the ring gear 39 to rotate. When the ring gear 39 rotates, it can drive the rotating ring 32 connected to the ring gear 39 to rotate. At this time, it can drive the cross plate 33 to rotate around the axis of the rotating ring 32 under the action of the two rotating rings 32. The cross plate 33 can drive the electromagnet 34 and the sponge wiper 35 to rotate around the motor shaft for one circle. By using the electromagnet 34, the metal debris attached to the outer wall of the motor shaft can be adsorbed first, so as to remove the metal debris on the outer wall of the motor shaft. By using the sponge wiper 35, the surface of the motor shaft can be wiped to clean the oil stain on the outer wall of the motor shaft, so as to realize the cleaning of the outer wall of the motor shaft, reduce the influence of metal debris and oil stain on the detection, and be beneficial to improving the detection accuracy.

[0033] As Figures 1 - 10 shown, the transmission assembly includes a second gear 44, a rack 45, a guide rail 46, a pull rope 47, a runner 48, a limit plate 49, a moving rod 50, a spring 51, a fixing plate 52, an L-shaped rod 54 and a synchronization component. The guide rail 46 is fixedly installed at the top of the detection table 11. The rack 45 is slidably arranged inside the guide rail 46. The fixing plate 52 is fixedly installed on one side wall of one end of the rack 45. The limit plate 49 is located on one side of the fixing plate 52 and is fixed on the detection table 11. The moving rod 50 is slidably inserted on the limit plate 49. One end of the moving rod 50 is fixedly connected to the fixing plate 52. The spring 51 is sleeved outside the moving rod 50. The two ends of the spring 51 are respectively connected to the limit plate 49 and the fixing plate 52. The second gear 44 is rotatably arranged at the top of the detection table 11. The second gear 44 meshes with the rack 45; The L-shaped rod 54 is fixedly installed on the side of the push plate 16 close to the first electric push rod 20. The runner 48 is rotatably arranged at the top of the detection table 11. One end of the pull rope 47 is connected to one end of the rack 45 close to the fixing plate 52. The other end of the pull rope 47 bypasses the runner 48 and is connected to the L-shaped rod 54. The synchronization component is located between the second gear 44 and the first gear 40; In the initial state, the spring 51 is in a stretched state; When the push plate 16 moves towards the side close to the motor shaft under the drive of the first electric push rod 20, at this time, under the action of the spring 51, it can drive the fixing plate 52 to move towards the direction close to the limit plate 49. The fixing plate 52 drives the rack 45 to slide inside the guide rail 46. Since the second gear 44 and the rack 45 are meshed with each other, when the rack 45 moves, it can drive the second gear 44 to rotate.

[0034] As Figures 1 - 10As shown, the synchronization component includes a driving wheel 41, a driven wheel 42 and a transmission belt 43. Two support plates are installed at the top of the detection table 11. The driving wheel 41 and the driven wheel 42 are respectively rotatably arranged on the two support plates. The first gear 40 is coaxially and fixedly connected to the driving wheel 41, the second gear 44 is coaxially and fixedly connected to the driven wheel 42, and the transmission belt 43 is sleeved on the driving wheel 41 and the driven wheel 42; When the second gear 44 rotates under the action of the rack 45, it can drive the driven wheel 42 to rotate. Under the action of the transmission belt 43, when the driven wheel 42 rotates, it can drive the driving wheel 41 to rotate, so as to realize the rotation of the first gear 40. When the first gear 40 rotates, the cross plate 33 can be rotated through the toothed ring 39. That is, when the push plate 16 moves to detect the length direction of the motor shaft, the electromagnet 34 and the sponge cleaner 35 can rotate around the motor base for one circle to clean the outer wall of the motor shaft, which is beneficial to the subsequent detection of the diameter of the motor shaft; After the detection is completed, the push plate 16 moves away from the motor shaft under the action of the first electric push rod 20. The push plate 16 drives the L-shaped rod 54 to move. Under the action of the pull rope 47, the rack 45 can be pulled back to its original position, and the spring 51 is stretched again.

[0035] As Figures 1 - 10 shown, the telescopic component includes a second electric push rod 36, a moving plate 56 and two second guide rods 37. The second electric push rod 36 is installed on one side of the cross plate 33. The moving plate 56 is located on the side of the cross plate 33 away from the second electric push rod 36. The sponge cleaner 35 is detachably installed on the moving plate 56, which is convenient for the user to replace the sponge cleaner 35 regularly. The output end of the second electric push rod 36 passes through the cross plate 33 and is connected to the moving plate 56. The two second guide rods 37 are symmetrically and slidably arranged on both sides of the cross plate 33. One end of each second guide rod 37 is fixedly connected to the moving plate 56; When it is necessary to clean the outer wall of the motor shaft, first control the second electric push rod 36 to work through the controller, so that the second electric push rod 36 can push the sponge cleaner 35 to move, so that the sponge cleaner 35 can move towards the motor shaft until the sponge cleaner 35 contacts the surface of the motor shaft, so as to facilitate the subsequent cleaning of the surface of the motor shaft. When the moving plate 56 moves, it can drive the second guide rod 37 to slide on the cross plate 33 to provide guidance for the moving plate 56.

[0036] As Figures 1 - 10As shown in the figure, the sliding component includes a mounting frame 24, a motor 25, a lead screw 26, a cover plate 27, and a slider 28. The mounting frame 24 is fixed to the top of the inspection table 11. Both ends of the lead screw 26 are rotatably provided on the mounting frame 24. The motor 25 is installed at one end of the mounting frame 24, and the output end of the motor 25 is fixedly connected to one end of the lead screw 26. The slider 28 is slidably arranged inside the mounting frame 24. The slider 28 is in threaded cooperation with the lead screw 26. Specifically, a threaded hole is provided on the slider 28, and the lead screw 26 is located inside the threaded hole and is in threaded cooperation with the threaded hole. The cover plate 27 is installed on one side of the mounting frame 24. The slider 28 extends out of the mounting frame 24 and is fixedly connected to the sliding frame 29; When it is necessary to detect the diameter of the motor shaft, by providing two second laser sensors 30, the distance between the output end of each second laser sensor 30 and the motor shaft is detected by using the two second laser sensors 30. Then, by subtracting the distance between each second laser sensor 30 detection end and the motor shaft from the distance between the two second laser sensors 30 detection ends, the diameter of the motor shaft can be obtained; When it is necessary to adjust the detection position, the controller controls the motor 25 to work. The motor 25 can drive the lead screw 26 to rotate. Since the lead screw 26 and the slider 28 are in threaded cooperation and the slider 28 slides inside the mounting frame 24, when the lead screw 26 rotates, it can drive the slider 28 to move inside the mounting frame 24, thereby driving the sliding frame 29 and the second laser sensor 30 on the sliding frame 29 to move, so as to detect the diameters at different positions of the motor shaft, improve the detection range and detection accuracy, and meet the use requirements.

[0037] As Figures 1 - 10 shown in the figure, a guide frame 53 is fixed to the top of the inspection table 11. The L-shaped rod 54 is slidably arranged on the guide frame 53. The guide frame 53 is provided to guide the L-shaped rod 54 and improve the stability of the L-shaped rod 54 during movement.

[0038] As Figures 1 - 10 shown in the figure, a collection trough 38 is installed above the inspection table 11. The collection trough 38 is located below the electromagnet 34. The collection trough 38 is used to collect the metal debris cleaned from the motor shaft. After the cleaning is completed, the electromagnet 34 is powered off, and at this time, the metal debris adsorbed on the electromagnet 34 can fall into the interior of the collection trough 38.

[0039] The specific working process of the present invention is as follows: When it is necessary to detect the length of the motor shaft, both ends of the two motor shafts are placed inside the mounting grooves 13 at the top of the two mounting plates 12, and one end of the motor shaft is made to contact the top plate 55. The two clamps 14 are used to position the motor shaft. The controller controls the first electric push rod 20 to work. The first electric push rod 20 can drive the push plate 16 to move towards one end of the motor shaft. When the push plate 16 contacts the other end of the motor shaft, at this time, both ends of the motor shaft are respectively in contact with the push plate 16 and the top plate 55. By using the first laser distance sensor 18 to detect the distance between the detection end of the first laser distance sensor 18 and the detection plate 17, the distance between the push plate 16 and the top plate 55 can be obtained, and thus the length of the motor shaft can be detected; When the push plate 16 moves towards the side of the motor shaft under the drive of the first electric push rod 20, at this time, under the action of the spring 51, it can drive the fixed plate 52 to move towards the direction close to the limit plate 49. The fixed plate 52 drives the rack 45 to slide inside the guide rail 46. Since the second gear 44 and the rack 45 are meshed with each other, when the rack 45 moves, it can drive the second gear 44 to rotate; When the second gear 44 rotates under the action of the rack 45, it can drive the driven wheel 42 to rotate. Under the action of the transmission belt 43, when the driven wheel 42 rotates, it can drive the driving wheel 41 to rotate, thereby realizing the rotation of the first gear 40. When the first gear 40 rotates, it can drive the gear ring 39 to rotate. When the gear ring 39 rotates, it can drive the rotating ring 32 connected to the gear ring 39 to rotate. At this time, it can drive the cross plate 33 to rotate around the axis of the rotating ring 32 under the action of the two rotating rings 32. The cross plate 33 can drive the electromagnet 34 and the sponge eraser 35 to rotate around the motor shaft for one circle. By using the electromagnet 34, the metal debris attached to the outer wall of the motor shaft can be adsorbed first, realizing the removal of the metal debris on the outer wall of the motor shaft. By using the sponge eraser 35, the surface of the motor shaft can be wiped, and the oil stain on the outer wall of the motor shaft can be cleaned, thereby realizing the cleaning of the outer wall of the motor shaft and reducing the influence of metal debris and oil stains on the detection, which is beneficial to improving the detection accuracy; That is, when the push plate 16 moves to detect the length direction of the motor shaft, the electromagnet 34 and the sponge eraser 35 can rotate around the motor base for one circle to realize the cleaning of the outer wall of the motor shaft, which is beneficial to the subsequent detection of the diameter of the motor shaft; When it is necessary to detect the diameter of the motor shaft, by setting two second laser sensors 30, the distance between the output end of each second laser sensor 30 and the motor shaft is detected by using the two second laser sensors 30. Then, by subtracting the distance between the detection end of each second laser sensor 30 and the motor shaft from the distance between the detection ends of the two second laser sensors 30, the diameter of the motor shaft can be obtained; When the detection position needs to be adjusted, the controller controls the motor 25 to work. The motor 25 can drive the lead screw 26 to rotate. Since there is a threaded fit between the lead screw 26 and the slider 28, the slider 28 slides inside the mounting frame 24. Therefore, when the lead screw 26 rotates, it can drive the slider 28 to move inside the mounting frame 24, thereby driving the sliding frame 29 and the second laser sensor 30 on the sliding frame 29 to move, so as to detect the diameters at different positions of the motor shaft, improve the detection range and detection accuracy, and meet the use requirements.

[0040] The beneficial effects of the present invention are specifically embodied as follows. The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
