Description

Technical Field

[0001] The present invention relates to the technical field of bearing vibration detection, and in particular to a bearing vibration detection device. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. During the operation of bearings, bearing vibration refers to all movements that deviate from the ideal position except for some inherent movements between bearing parts required by their functions. After the bearings are processed, an oscillating structure is required to apply oscillation to the bearing ring surface.

The bearing vibration detection device, through the interaction of the first threaded rod, the restraining body, and the traction plate, can drive the traction plate to move up and down when the first threaded rod is rotated.

[0015] 1. The present invention sets a bevel gear, a bevel gear ring, a threaded rod and a contact drum wheel. The bevel gear ring elastically connected to the mounting ring drives the bevel gear to rotate by meshing with the bevel gear. The rotating bevel gear has a tendency to push the longitudinal plate close to the axis of the mounting ring by meshing with the threaded rod. The pushing structure pushes the bearing to move to the right from the leftmost mounting ring. The longitudinal plate pushes the contact drum wheel to contact the outer ring surface of the bearing, controls the vibration detection structure to contact the outer ring surface of the bearing for detection, drives the contact drum wheel to rotate through the driving wheel on the prism A, and drives the contact drum wheel to rotate the bearing in contact, so that the vibration detection structure can detect the ring surfaces of different bearing rings at different positions. The pushing structure continuously pushes the new bearing into the inner ring side of the mounting ring, and at the same time pushes the bearing on the inner side of the mounting ring to move continuously to the right, so that multiple bearings can be detected at the same time.

[0016] 2. The present invention provides a bidirectional threaded barrel, a prism shaft B, a support plate, a distance ring and an inner push block. The rotating prism shaft B drives multiple bidirectional threaded barrels to rotate synchronously. When the bidirectional threaded barrel rotates forward and backward, the distance between two adjacent mounting rings changes, and the distance between the distance ring and the leftmost mounting ring changes synchronously. When the electromagnetic head pushes the bearing to the right, the inner push block follows the electromagnetic head to move to the right and gradually approaches the push plate. When the push plate contacts the distance ring, the electromagnetic head pushes the bearing into the leftmost mounting ring, so that bearings of different widths can be detected. After changing the distance between the mounting rings, the vibration detector can always be in the center position of the bearing.

[0017] 3. The present invention provides grooved and protruding plates. When the distance between the mounting rings changes, the mounting rings drive the corresponding grooved and protruding plates to slide and fit between adjacent grooved and protruding plates. When the bevel gear rings are rotated, the bevel gear rings drive all the bevel gear rings to rotate synchronously through the connection between the grooved and protruding plates, so that the distance between all the contact drum wheels and the axis of the mounting rings is equal, which facilitates the smooth rightward movement of the bearings.

[0018] 4. The present invention provides a bolt pressure rod and a bent rod, and by rotating the bolt pressure rod to engage and disengage the bent rod and contact the rod frame, the angle between the bent rod and the vibration detector can be changed. Then, by rotating the bolt pressure rod in the opposite direction to fix the bent rod and the rod frame together, the angle at which the vibration detector detects the bearing can be changed.

When the bidirectional threaded cylinder 2 rotates forward and backward, it can respectively drive the two connected mounting rings 3 to approach or move away from each other.

[0032] The inner ring surface of the mounting ring 3 is provided with a plurality of retractable vibration detection structures 4. A longitudinal plate 6 is provided on the inner ring side of the mounting ring 3 and between each adjacent two vibration detection structures 4. The vibration detection structure 4 includes a double-headed power telescopic frame 41 and a rod frame 42. The telescopic end of the double-headed power telescopic frame 41 is fixed to the rod frame 42, and the other end of the rod frame 42 is rotatably plugged with a bent rod 43. The other end of the bent rod 43 is provided with a vibration detector 45. The double-headed power telescopic frame 41 can drive the rod frame 42 to move through power telescoping, and can control the vibration detector 45 to approach the bearing for bearing detection. A bolt pressure rod 44 is threadedly plugged into the right side of one end of the bent rod 43 connected to the rod frame 42. The bolt pressure rod 44 is in contact with the rod frame 42 and pressed tightly. The bolt pressure rod 44 is rotated to loosen the bent rod 43 relative to the bent rod 43, so that the bolt pressure rod 44 is away from the rod frame 42, so that the vibration detector 45 can be adjusted, and the angles of different vibration detectors 45 in different mounting rings 3 can be controlled.

[0033] The side of the longitudinal plate 6 close to the axis of the mounting ring 3 is rotatably connected to the contact drum wheel 7, and the side of the longitudinal plate 6 away from the axis of the mounting ring 3 is fixed with a vertical telescopic rod 8, the other end of the vertical telescopic rod 8 is fixed to the inner ring surface of the mounting ring 3, and the vertical telescopic rod 8 limits the movement trajectory of the longitudinal plate 6, and the side of the longitudinal plate 6 away from the axis of the mounting ring 3 is fixed with a threaded rod 10, the threaded rod 10 slides through the inner ring surface of the mounting ring 3, and the end of the threaded rod 10 located outside the mounting ring 3 is threadedly sleeved with a bevel gear 11, which is rotatably inserted into the outer ring surface of the mounting ring 3, and the outer ring surface of the mounting ring 3 is elastically rotatably sleeved with a bevel gear ring 12, and the left side of the bevel gear ring 12 is meshed with the adjacent bevel gear 11, and the bevel gear ring 12 elastically connected to the mounting ring 3 engages with the threaded rod 10 by driving the bevel gear 11 to rotate, and has a tendency to push the longitudinal plate 6 close to the axis of the mounting ring 3.

[0034] A plurality of groove protrusion plates 9 are fixed to the outer ring surface of the bevel gear ring 12. The cross-section of the right end of the groove protrusion plate 9 is smaller than the cross-section of the left end of the groove protrusion plate 9. The left end of the groove protrusion plate 9 is a groove-shaped structure that cooperates with the right end of the groove protrusion plate 9. The two ends of the groove protrusion plate 9 are respectively slidably matched with the adjacent groove protrusion plates 9 on the left and right sides. The groove protrusion plates 9 can make all the bevel gear rings 12 rotate synchronously by cooperating with the adjacent groove protrusion plates 9.

[0035] The inner ring surface of the main ring frame 1 is equipped with a pushing structure 5, which includes a power telescopic rod 51 and an electromagnetic head 52. The electromagnetic head 52 is coaxially fixed with the telescopic end of the power telescopic rod 51, and the fixed end of the power telescopic rod 51 is fixed to the left side of the main ring frame 1. When the power telescopic rod 51 pushes the electromagnetic head 52 to move to the right, the electromagnetic head 52 can adsorb the bearing. When the power telescopic rod 51 drives the electromagnetic head 52 to move to the left, the electromagnetic head 52 is separated from the bearing adsorption, and a support plate 53 is provided below the electromagnetic head 52. The lower end of the plate 53 is fixed to the main ring frame 1. When the new bearing is placed on the support plate 53, the right end of the main ring frame 1 is slidably sleeved with a distance ring 54. The left end of the mounting ring 3 connected to the main ring frame 1 is slidably sleeved on the outer surface of the distance ring 54. The left end face of the distance ring 54 is flush with the left end face of the adjacent mounting ring 3. The distance ring 54 is threadedly sleeved on the left end of the adjacent bidirectional threaded barrel 2. When the bidirectional threaded barrel 2 rotates and engages with the corresponding mounting ring 3 and the distance ring 54, the distance between the distance ring 54 and the mounting ring 3 is synchronously controlled.

[0036] The bottom surface of the electromagnetic head 52 is fixed with an inner push block 521, which is slidably inserted into the upper surface of the support plate 53. The upper surface of the support plate 53 is provided with a groove structure that matches the inner push block 521. A push plate 522 is provided on the right side of the support plate 53. A tension telescopic rod 523 is fixed to the left side of the push plate 522. The support plate 53 is fixedly sleeved on the fixed end of the tension telescopic rod 523. The tension telescopic rod 523 has a tendency to pull the push plate 522 to move to the left. The right side of the inner push block 521 The distance between the surface and the right side surface of the electromagnetic head 52 is equal to the thickness of the push plate 522. The upper surface of the push plate 522 is flush with the upper surface of the support plate 53. When the electromagnetic head 52 moves, it drives the inner push block 521 to slide inside the groove structure of the support plate 53. When the electromagnetic head 52 pushes the bearing into the leftmost mounting ring 3, when the push plate 522 contacts the distance ring 54, the right side surface of the electromagnetic head 52 is flush with the left side surface of the distance ring 54, so that the vibration detector 45 is located in the middle part of the bearing.

[0037] The inner ring surface of the mounting ring 3 is provided with a driving wheel 13, which contacts one of the contact cylinder wheels 7. The driving wheel 13 is rotatably connected to the adjacent longitudinal plate 6. A prism shaft A14 is provided on the right side of the main ring frame 1. The prism shaft A14 is located on the inner ring side of each mounting ring 3. A vertical telescopic rod 15 is installed on the inner ring surface of the main ring frame 1. A motor 16 is fixed to the lower end of the vertical telescopic rod 15. The output end of the motor 16 is fixed to the left end of the prism shaft A14. Each driving wheel 13 is slidably sleeved on the outer surface of the prism shaft A14. The prism shaft A14 drives multiple driving wheels 13 to rotate, and the driving wheels 13 drive the corresponding bearings to rotate through the contact cylinder wheels 7 they contact.

[0038] A plurality of elastic limiting plates 18 are fixed to the inner ring surface of the main ring frame 1. The distance between the left ends of the plurality of elastic limiting plates 18 is greater than the distance between the right ends of the plurality of elastic limiting plates 18. The plurality of elastic limiting plates 18 are evenly distributed in an array around the axis of the main ring frame 1. The plurality of mounting rings 3 are coaxially arranged with the main ring frame 1. When the electromagnetic head 52 pushes the adsorbed bearing to move to the right, the plurality of elastic limiting plates 18 gradually push the bearing to be coaxial with the mounting ring 3, so as to facilitate the bearing to enter between the plurality of contact cylinder wheels 7 on the inner side of the mounting ring 3.

[0039] The working principle is as follows: the electromagnetic head 52 can control the adsorption of the bearing, and the bevel gear ring 12 elastically connected to the mounting ring 3 drives the bevel gear 11 to rotate and engage with the threaded rod 10, which has a tendency to push the longitudinal plate 6 close to the axis of the mounting ring 3. The rotating prism shaft B19 drives multiple bidirectional threaded cylinders 2 to rotate synchronously. When the bidirectional threaded cylinder 2 rotates forward and backward, the distance between the two adjacent mounting rings 3 changes, and the distance between the distance ring 54 and the leftmost mounting ring 3 changes synchronously. When the electromagnetic head 52 pushes the bearing to move to the right, the inner push block 521 follows the electromagnetic head 52 to move to the right and gradually approaches the push plate 522. When the push plate 522 contacts the distance ring 54, the electromagnetic head 52 pushes the bearing into the leftmost mounting ring 3, and then The contact cylinder wheel 7 presses the outer ring surface of the bearing to make the bearing coaxial with the mounting ring 3. The motor 16 drives all the driving wheels 13 to rotate through the prism shaft A14. The driving wheel 13 drives the bearing to rotate through the contact cylinder wheel 7 it contacts. The bevel gear ring 12 drives all the bevel gear rings 12 to rotate synchronously through the connection between the groove protruding plate 9. When the electromagnetic head 52 continuously pushes the new bearing to be tested into the mounting ring 3 on the right, the bearing on the inner side of the right mounting ring 3 gradually moves to the right, and the bearing on the far right detaches from the mounting ring 3 and falls off. By loosening the bolt pressure rod 44, the angle of the vibration detector 45 on the inner ring side of each mounting ring 3 is changed, so that the bearing can be detected in different directions as the bearing gradually moves to the right.

[0040] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
