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 rotation, reduce friction, and ensure the correct position of the shaft, which is crucial to the reliability of the entire mechanical system. Therefore, bearing inspection is critical to ensure its normal operation and the reliability of the entire system. Bearing inspection usually includes dynamic performance testing, dimensional accuracy testing, and surface quality testing, etc., in order to verify whether the bearing meets the standard requirements and can be used safely and reliably.

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

[0004] The patent fixes the bearing body by an arc-shaped clamping block in the clamping mechanism, and adjusts the position of the infrared digital tachometer in combination with an adjustment mechanism to ensure that the bearing body does not shake during the detection operation, thereby making the detection process more stable; however, due to the clamping method, the outer ring position of the bearing is relatively fixed, resulting in the focus on the speed test of the inner ring of the bearing during the detection process, resulting in the neglect of 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 perform speed tests on the inner and outer rings of the bearing separately.

Therefore, they cannot be understood as limitations on the present invention.

[0035] In addition, the terms "first", "second" and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the 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, such as Figure 1-Figure 6 As shown, including:

[0037] The test bench 1 is a hollow frame separated into front and rear parts, and has a partition in the middle extending in the left and right directions. The test bench 1 is used as the main platform for testing the bearing 100.

[0038] The mounting cylinder 11 is fixedly arranged at the center of the partition of the test bench 1. A forward and reverse motor 12 with an output end facing upward is fixedly installed on the lower side of the mounting cylinder 11. A turntable 13 connected to the output shaft of the forward and reverse motor 12 is also rotatably arranged on the mounting cylinder 11. The turntable 13 is placed under the top surface of the test bench 1, and two groups of slots are opened on the turntable 13 along the circumferential direction, which can help promote the synchronous operation of the detection components.

[0039] There are two sets of ball cylinders 2, which are telescopically arranged on the top surfaces of both sides of the test bench 1, so that the ball cylinders 2 can be retracted or extended on the test bench 1 to adapt to the detection or placement operation of the bearing 100. Each set of ball cylinders 2 is arranged separately with inner and outer rings along the circumference of the mounting cylinder 11, so as to provide auxiliary support for the inner and outer ring positions of the bearing 100 respectively. When the bearing 100 is detected in terms of speed, the force of the rotation of the balls in the inner and outer ring ball cylinders 2 can assist in pushing the bearing 100 to rotate and make its movement smoother;

[0040] The speed sensors 3 are arranged in a group on the front top surface of the test bench 1 and are adapted to the layout of the ball rollers 2 and integrated between the ball rollers 2 on the same side to monitor the rotation speeds of the inner and outer rings of the bearing 100. By setting two speed sensors 3, the inner and outer rings of the bearing 100 can be independently tested to achieve separate testing and present more accurate test results.

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

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

[0043] like Figure 3-Figure 5 As shown, the two groups of slots are arc slot one 131 and arc slot two 132. The setting of arc slot one 131 can realize the synchronous pushing of the clamping part 4 and the switching part 5, and the arc slot two 132 is opened for the air flow of the switching part 5. The arc slot one 131 and arc slot two 132 of the same group are symmetrically arranged and staggered on the turntable 13, and slots compatible with the two arc slots two 132 are also opened on the top surfaces of both sides of the test bench 1.

[0044] like Figure 1-Figure 3 As shown, the clamping portion 4 includes support plates 41 symmetrically arranged on the partition of the test bench 1, and the facing sides of the two support plates 41 are penetrated by outer clamping plates 42 and the two form a sliding fit. A moving seat 43 is also arranged on the outer clamping plate 42. The middle position of the bottom of the moving seat 43 is a convexity, and is embedded in the arc groove 131 on the same side to cooperate with the rotation of the turntable 13 to push the outer clamping plate 42 to move, and the moving seat 43 is provided with an inner clamping plate 44 for fixing the inner ring of the bearing 100. The shape characteristics of the arc groove 131 are utilized to cooperate 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 bearing 100 can be clamped separately by the inner and outer rings during the detection process, ensuring the stability during the detection and synchronizing the position requirements of subsequent separate detection.

[0045] like Figure 1 , Figure 4-Figure 6 As shown, the switching part 5 includes a mounting plate 51 symmetrically arranged inside the test bench 1, a rotating plate 52 is penetrated and rotatably arranged 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 resetting operation of the rotating plate 52, and an air pipe 53 for blowing the bearing 100 to rotate is arranged on the mounting plate 51, and the air ports of the air pipes 53 on both sides are arranged relatively to each other to cooperate with the operation of the turntable 13 to realize the double push on the rotation of the bearing 100, and the top of the air port of the air pipe 53 passes through the arc groove 132 and the notch on the same side, so that the airflow can be blown onto the bearing 100 more easily and can fit the moving trajectory of the turntable 13. In order to allow the airflow to be sprayed onto the bearing 100 more evenly, a guide seat 54 for guiding the turning of the air pipe 53 and a vertical pole 55 connected to a pull rope 56 are also provided on the mounting plate 51, wherein the guide seat 54 has a U-shaped notch on the side facing the air pipe 53, which can adapt to the turning of the rotating plate 52 and the air pipe 53 to limit the positions of both, so that the airflow spraying position can be more precise. Here, the end of the pull rope 56 will pass through the guide seat 54 on the same side and be connected to the rotating plate 52, so as to pull the rotating plate 52 together with the air pipe 53 to move, and contact rods 57 are provided on both sides of the bottom of the turntable 13, which are respectively in contact with the pull rope 56 on the same side, so as to change the spraying direction of the air pipe 53.

[0046] like Figure 4 As shown, it also includes a positioning claw 111. Six positioning claws 111 for limiting the position of the bearing 100 are arranged at circumferential intervals on the surface of the mounting tube 11, and the bottom ends of the positioning claws 111 are in contact with the surface of the turntable 13, which can limit the position of the bearing 100 during placement, so that it can be more easily aligned with the center position of the mounting tube 11 when placed, so as to facilitate subsequent detection work.

[0047] When the bearing 100 needs to be inspected, the equipment is placed on a stable table, and then the bearing 100 to be inspected is passed through the mounting tube 11 and placed on the test bench 1. At this time, the ball cylinder 2 is in an extended state, so that the bottom of the inner and outer rings of the bearing 100 can respectively contact the ball cylinder 2 and the speed sensor 3 in the same circumferential direction. Here, there will be a certain gap between the positioning claw 111 and the inner ring surface of the placed bearing 100, so as to calibrate and align the center positions of the bearing 100 and the mounting tube 11. Then the air pipe 53 is connected to the air pump to start the forward and reverse motor 12. When the forward and reverse motor 12 drives the turntable 13 to rotate forward, the rotation of the turntable 13 will drive the moving seat 43 through the arc groove 131. The rotating plate 52 connected to the rotating plate 52 moves and the inner plate 44 moves away from the bearing 100, and the outer plate 42 gradually approaches and contacts the outer ring of the bearing 100. At the same time, as the rotating plate 13 rotates, the contact rods 57 on both sides will contact the corresponding pull ropes 56, thereby pulling the pull ropes 56 on both sides toward the center position. With the corresponding vertical rods 55 as the fulcrum, the pull ropes 56 are pulled and the rotating plate 52 connected thereto moves, so that the rotating plate 52 rotates on the mounting plate 51, and the connected torsion springs are deformed accordingly. As the rotating plate 52 rotates, the connected air pipe 53 will be driven 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 groove 131, and the outer clamping plates 42 on both sides are attached to and clamped on the outer ring of the bearing 100. The air outlet of the air pipe 53 is aligned between the ball and the inner ring of the bearing 100, and then the air pump is started to fill the air pipe 53. The strong airflow is ejected quickly and drives the ball 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. Then the inner ring of the bearing 100 is driven by the airflow to rotate, and the speed sensor 3 is directly used to measure the moving The rotation speed of the bearing 100 in the bearing 100 is sensed, so as to transmit the signal of the relevant detection data to the control center, thereby completing the rotation speed detection of the inner ring of the bearing 100; on the contrary, when the rotation speed of the outer ring of the bearing 100 needs to be detected, the forward and reverse motor 12 reverses and drives the turntable 13, the contact rod 57 is separated from the contact with the pull rope 56, the torsion spring is reset accordingly, and drives 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 ball, and at the same time the outer clamping plate 42 is separated from the contact, and the inner clamping plate 44 is fitted with the bearing 100 to achieve clamping and fixing, and then the above operation can be repeated to detect the rotation speed of the outer ring of the bearing 100;

[0048] Embodiment 2: Based on embodiment 1, 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 Fig. 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 solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
