Description

Technical Field

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

[0002] Bearings are key components in mechanical systems. Their function is to support the shaft during rotational motion, reduce friction, and ensure the correct position of the shaft, which is crucial for the reliability of the entire mechanical system. Therefore, the detection of bearings is very critical to ensure their normal operation and the reliability of the entire system. Bearing detection usually includes dynamic performance testing, dimensional accuracy detection, surface quality detection, etc., aiming to verify whether the bearings meet the standard requirements and can be used safely and reliably.

[0003] According to the bearing speed testing device with the authorization announcement number CN115060923B, it includes a testing platform. A connection groove is opened at the top end of the testing platform, and H-shaped connection frames are fixedly connected to the inner walls on both sides of the connection groove; a forward and reverse motor, which moves the rack. When the rack moves, it drives the T-shaped slider fixed at the bottom, so that the T-shaped slider can slide on the top end of the first fixing plate and also on the lower inner wall of the T-shaped concave plate. While the T-shaped slider slides, it drives the infrared digital tachometer fixed at the bottom to move.

[0004] This patent fixes the bearing body through the arc-shaped clamping block in the clamping mechanism, and combines the adjustment mechanism to adjust the position of the infrared digital tachometer to ensure that the bearing body does not shake during the detection operation, thus making the detection process more stable; however, due to the clamping method, the position of the outer ring of the bearing is relatively fixed, resulting in a greater emphasis on the speed test of the inner ring of the bearing during the detection process, and neglecting the detection of defects in the outer ring of the bearing. In addition, in some cases, in order to obtain more accurate detection results, it is necessary to test the rotational speeds of the inner and outer rings of the bearing separately. Therefore, this device still has room for further optimization in achieving comprehensive and accurate bearing detection. Summary of the Invention

[0013] Preferably, the clamping part includes support plates symmetrically arranged on the partition of the test bench. Outer clamping plates are respectively inserted through the opposite sides of the two support plates and form a sliding fit therebetween. A moving seat is also arranged on the outer clamping plate. A protruding part is arranged at the bottom of the moving seat and is embedded in the arc-shaped slot one on the same side to cooperate with the rotation of the turntable to push the outer clamping plate to move, and an inner clamping plate for fixing the inner ring of the bearing is arranged on the moving seat.

[0014] Preferably, the switching part includes mounting plates symmetrically arranged inside the test bench. A rotating plate is rotatably arranged on the mounting plate. A torsion spring is arranged between the rotating plate and the mounting plate. An air pipe for blowing the bearing to rotate is arranged on the mounting plate. The top end of the air pipe passes through the arc-shaped slot two and the slot opening on the same side. A guide seat for guiding the turning of the air pipe and a vertical rod connected with a pull rope are also arranged on the mounting plate. The end of the pull rope passes through the guide seat on the same side and is connected with the rotating plate to pull the rotating plate together with the air pipe to move. Contact rods respectively in contact with the pull ropes on the same side are arranged on both sides of the bottom of the turntable.

[0015] Preferably, a shielding part for shielding the air flow is arranged between the support plates. The shielding part includes a connecting seat and a socket respectively arranged on the two support plates. A shielding cover in contact with the bearing is rotatably arranged on the connecting seat. The shielding cover is used for shielding and blocking the air flow direction. The other end of the shielding cover is placed on the socket, and a plug rod in abutting cooperation with the shielding cover is inserted on the socket.

[0016] Preferably, it further includes an inclined plate. The bottom surface of the shielding cover is concave. Segmented inclined plates are arranged along the circumferential direction in the concave part of the shielding cover.

Furthermore, by the rotation of the turntable, the position of the air pipe is synchronously pushed to change, enabling the independent operation of the detection of the inner and outer rings of the bearing, achieving more comprehensive bearing detection, and realizing the double improvement of both simple operation and detection accuracy.

[0035] In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. The technical solutions of the present invention will be clearly and completely described below with reference to the drawings. It should be noted that the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] Embodiment 1: A bearing detection device for bearing production and processing, as Figures 1-6 shown, includes:

[0037] The test bench 1 is a hollow frame separated front and back, with a partition extending left and right in the middle. The test bench 1 serves as the main platform for the detection of the bearing 100.

[0038] The installation cylinder 11 is fixedly arranged at the central position of the partition of the test bench 1. A forward and reverse motor 12 with an upward output end is fixedly installed on the lower side inside the installation cylinder 11. A turntable 13 connected to the output shaft of the forward and reverse motor 12 is also rotatably arranged on the installation cylinder 11. The turntable 13 is located below the top surface of the test bench 1, and two groups of slots are circumferentially provided on the turntable 13, which can assist in promoting the synchronous operation of the detection components.

[0039] There are two groups of ball cylinders 2. The two groups of ball cylinders 2 are respectively telescopically arranged on the top surfaces of both sides of the test bench 1, so that the ball cylinders 2 can retract or extend on the test bench 1 to adapt to the detection or placement operations of the bearing 100. Each group of ball cylinders 2 is arranged in a layout with the inner and outer rings separated along the circumference of the installation cylinder 11, so as to respectively provide auxiliary support for the positions of the inner and outer rings of the bearing 100. When the rotational speed of the bearing 100 is detected, the acting force of the rotation of the balls in the inner and outer ring ball cylinders 2 can make it easier to assist in promoting the rotation of the bearing 100 and make its movement smoother.

[0040] There is one group of speed measurement sensors 3. The speed measurement sensors 3 are arranged on the front top surface of the test bench 1 and are adapted to the layout of the ball cylinders 2, and are incorporated between the ball cylinders 2 on the same side to monitor the rotational speeds of the inner and outer rings of the bearing 100. With the setting of two speed measurement sensors 3, the inner and outer rings of the bearing 100 can be independently detected to achieve separate detection and present more accurate detection results.

[0041] The clamping parts 4 are respectively arranged on both sides of the partition of the test bench 1 to fix the positions of the inner and outer rings of the bearing 100, and can cooperate with the operation of the turntable 13 to switch the clamping of the inner and outer rings of the bearing 100.

[0042] The switching part 5 is symmetrically arranged front and back inside the test bench 1, and can cooperate with the rotation of the turntable 13 and quickly switch to drive the rotation of the inner or outer ring of the bearing 100 for rotational speed testing, realizing the separate detection of the inner or outer ring of the dynamic bearing 100 to achieve a more accurate detection effect.

[0043] As Figures 3-5 shown, the two groups of slots are respectively the arc-shaped slot one 131 and the arc-shaped slot two 132. The setting of the arc-shaped slot one 131 can achieve the synchronous promotion of the clamping part 4 and the switching part 5, while the arc-shaped slot two 132 is opened for the air flow of the switching part 5. The arc-shaped slot one 131 and the arc-shaped slot two 132 of the same group are symmetrically arranged and staggeredly distributed on the turntable 13, and slot openings adapted to the two arc-shaped slots two 132 are also provided on the top surfaces of both sides of the test bench 1.

[0044] AsFigures 1-3 As shown, the clamping part 4 includes support plates 41 symmetrically arranged on the left and right sides of the partition of the test bench 1. Outer clamping plates 42 are inserted through the opposite sides of the two support plates 41 and form a sliding fit therebetween. A moving seat 43 is further arranged on the outer clamping plate 42. A protruding part is arranged at the middle position of the bottom of the moving seat 43, and the protruding part is embedded in the arc-shaped groove 131 on the same side to cooperate with the rotation of the turntable 13 to push the outer clamping plate 42 to move. An inner clamping plate 44 for fixing the inner ring of the bearing 100 is arranged on the moving seat 43. By using the shape characteristics of the arc-shaped groove 131, it cooperates with the operation of the turntable 13 to synchronously push the outer clamping plate 42 and the inner clamping plate 44 to move, so that the inner and outer rings of the bearing 100 can be separately clamped during the detection process, ensuring the stability during detection and synchronizing the position requirements for subsequent separate detections.

[0045] As Figure 1 、 Figures 4-6 shown, the switching part 5 includes mounting plates 51 symmetrically arranged in the front and back of the test bench 1. A rotating plate 52 is arranged through and rotatably in the middle position of the mounting plate 51. A torsion spring is arranged between the rotating plate 52 and the mounting plate 51, which can provide elastic support for the reset operation of the rotating plate 52. An air pipe 53 for blowing the bearing 100 to rotate is arranged on the mounting plate 51. The air outlets of the two air pipes 53 on both sides are arranged opposite to each other to cooperate with the operation of the turntable 13 to realize double pushing for the rotation of the bearing 100. The top of the air outlet of the air pipe 53 passes through the arc-shaped groove 132 and the notch on the same side, so that the air flow can more easily blow onto the bearing 100, and can conform to the moving track of the turntable 13 to make the air flow spray more evenly on the bearing 100. A guide seat 54 for guiding the turning of the air pipe 53 and a vertical rod 55 connected with a pull rope 56 are further arranged on the mounting plate 51. A U-shaped notch is opened on the side of the guide seat 54 facing the air pipe 53, which can adapt to the turning of the rotating plate 52 and the air pipe 53 to limit their positions, so that the air flow spraying position can be more accurate. Here, the end of the pull rope 56 passes through the guide seat 54 on the same side and is connected to the rotating plate 52 to pull the rotating plate 52 together with the air pipe 53 to move. Contact rods 57 respectively in contact with the pull rope 56 on the same side are arranged on both sides of the bottom of the turntable 13 to change the spraying direction of the air pipe 53.

[0046] As Figure 4 shown, it further includes positioning claws 111. Six positioning claws 111 for restricting the position of the bearing 100 are arranged at intervals in the circumferential direction on the surface of the mounting cylinder 11, and the bottom ends of the positioning claws 111 are attached to the surface of the turntable 13, which can restrict the position of the bearing 100 during placement, so that it can be more easily aligned with the center position of the mounting cylinder 11 during placement for subsequent detection work.

[0047] When it is necessary to detect the bearing 100, the device is placed on a stable tabletop, and then the bearing 100 to be detected is passed through the mounting cylinder 11 and placed on the test bench 1. At this time, the ball cylinder 2 is in the extended state, so that the bottom parts of the inner and outer rings of the bearing 100 can be in contact with the ball cylinder 2 and the speed measurement sensor 3 in the same circumferential direction respectively. Here, there will be a certain gap between the positioning claw 111 and the inner ring surface of the placed bearing 100 to calibrate and align the center positions of the bearing 100 and the mounting cylinder 11. Subsequently, the air pipe 53 is connected to the air pump, and the forward and reverse motor 12 can be started. When the forward and reverse motor 12 drives the turntable 13 to rotate forward, as the turntable 13 rotates, it will drive the moving seat 43 to move along the arc-shaped groove 131, and synchronously pull the two side moving seats 43 towards the center position of the turntable 13. The moving seat 43 drives the corresponding outer clamping plate 42 to slide on the support plate 41. Then, the inner clamping plate 44 moves away from the bearing 100, while the outer clamping plate 42 gradually approaches and contacts the outer ring part of the bearing 100. At the same time, as the turntable 13 rotates, the contact rods 57 on both sides will contact the corresponding pull ropes 56, and then pull the two side pull ropes 56 towards the center position. Taking the corresponding vertical rod 55 as the fulcrum, after the pull rope 56 is pulled, it will drive the rotating plate 52 connected to it to move, so that the rotating plate 52 rotates on the mounting plate 51, and the connected torsion spring deforms accordingly. As the rotating plate 52 rotates, it will drive the connected air pipe 53 to operate synchronously. When the rotating plate 52 rotates to fit the inner wall of one side of the U-shaped notch of the guide seat 54, the moving seat 43 moves to the end of the arc-shaped groove 131, and the two side outer clamping plates 42 are attached to and clamp the outer ring of the bearing 100. The air outlet of the air pipe 53 is aligned between the balls and the inner ring of the bearing 100. Then, the air pump is started to fill the air pipe 53 with air. The strong air flow is quickly ejected and pushes the balls and the inner ring of the bearing 100 to rotate synchronously. During the rotation detection process, the ball cylinder 2 will retract into the test bench 1, and the bearing 100 will be separated from the contact with the ball cylinder 2. Subsequently, the inner ring of the bearing 100 is driven to rotate by the air flow, and the speed measurement sensor 3 directly senses the rotation speed of the moving bearing 100, and conveys the signal of the relevant detection data to the control center, thus completing the rotation speed detection of the inner ring of the bearing 100; conversely, when it is necessary to detect the rotation speed of the outer ring of the bearing 100, the forward and reverse motor 12 rotates in reverse to drive the turntable 13. The contact rod 57 is separated from the contact with the pull rope 56, and the torsion spring is reset accordingly, driving the rotating plate 52 to reset to the other side of the guide seat 54, so that the air outlet of the air pipe 53 is aligned with the position between the outer ring of the bearing 100 and the balls. At the same time, the outer clamping plate 42 will be separated from the contact, and the inner clamping plate 44 will be attached to the bearing 100 to achieve clamping and fixing. Subsequently, the above operations can be repeated to detect the rotation speed of the outer ring of the bearing 100;

[0048] Embodiment 2: On the basis of Embodiment 1, as Figure 1 、 Figure 7 and Figure 8As shown, a shielding portion 6 for shielding airflow is provided between the two support plates 41, and the shielding portion 6 includes a connecting seat 61 and a socket 63 respectively provided on the top of the two support plates 41, and a shielding cover 62 abutting against the bearing 100 is rotatably provided on the connecting seat 61, and the shielding cover 62 is used to shield and block the airflow direction, and the right end of the shielding cover 62 is placed on the socket 63, and a plug rod 64 abutting against the shielding cover 62 is inserted into the socket 63, which can limit the rotation of the shielding cover 62, thereby ensuring that the shielding cover 62 covers the bearing 100 to block the airflow.

[0049] like Figure 8 As shown, it also includes an inclined plate 621. The bottom surface of the shielding cover 62 is concave. A segmented inclined plate 621 is circumferentially arranged at the concave part of the shielding cover 62. Two adjacent inclined plates 621 are connected to each other to form a concave-convex spacing state, which is suitable for diverting and guiding the airflow.

[0050] like Figure 9 As shown, a pushing mechanism 7 for pushing the bearing 100 is also provided on the support plate 41. The pushing mechanism 7 includes a sliding rod 71 which is symmetrical front and back and slidingly arranged on one side support plate 41. The sliding rod 71 and the connecting seat 61 are on the same side, and a pushing rod 72 for pushing the bearing 100 is arranged between the bottom ends of the two sliding rods 71. The right end of the pushing rod 72 extends to the detection table 1 so as to contact the bearing 100. Push rods 73 which contact and cooperate with the sliding rod 71 on the same side are arranged on the front and rear sides of the end of the shielding cover 62, so that the rotation of the shielding cover 62 and the movement of the pushing rod 72 are linked, so that the bearing 100 can be taken out immediately after the detection, which brings convenience to the operation and can improve the overall work efficiency.

[0051] In order to ensure the accuracy of the detection of the bearing 100, the shielding cover 62 can be rotated and knocked down to rotate on the connecting seat 61, and then the other end of the shielding cover 62 is against the socket 63, and then the plug rod 64 is inserted into the socket 63, and the end of the shielding cover 62 is pressed against the position to fix it. Then, during the detection process, the inclined plate 621 in the shielding cover 62 can be used to guide the airflow to prevent the airflow from being loose and make the airflow more condensed. After the detection of the bearing 100 is completed, the plug rod 64 is pushed away, and the shielding cover 62 is rotated and opened. As the shielding cover 62 rotates, the push rod 73 thereon will contact the corresponding slide bar 71, and then push the slide bar 71 upward, driving the push rod 72 connected thereto to move upward synchronously to push the bearing 100, so as to take the bearing 100.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
