DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0036] like Figure 1-10 As shown, a bearing noise detection device described in an embodiment of the present invention includes a body 1, a driving part 2, a clamping part 3 and a detection part 4, the clamping part 3 includes a No. 1 clamping component 31 and a No. 2 clamping component 32 for clamping the inner and outer circles of the bearing respectively, the driving part 2 is used to drive the No. 1 clamping component 31 to rotate, and the detection part 4 includes a No. 1 detection head 41 for detecting the amplitude of the bearing, characterized in that the No. 1 clamping component 31 includes a No. 1 clamping jaw 311 for clamping, a No. 1 rod 312 is fixedly installed above the No. 1 clamping jaw 311, and a slider 313 is slidably installed on the No. 1 rod 312, the driving part 2 includes a No. 2 rod 21 and an insert block 22 rotatably installed on the body 1, and the driving part 2 drives the No. 1 clamping component 31 to rotate by inserting the insert block 22 into the interior of the slider 313.

[0037] Specifically, the process of noise detection by vibration method is as follows: control two clamping assemblies to fix the inner ring and outer ring of the bearing respectively, control the driving part 2 to drive one of the clamping assemblies to rotate, and the rotation of the clamping assembly drives the inner ring of the bearing to rotate synchronously. At this time, the first detection head 41 performs amplitude detection on the outer ring of the bearing, that is, the action of noise detection on the bearing is realized. In the process of the driving part 2 of the existing device driving the bearing to rotate, there is a situation where the vibration generated by the driving part 2 itself interferes with the detection result;

[0038] In the initial state, the insert block 22 is inserted into the slider 313. Before working, the inner ring and outer ring of the bearing are clamped by the No. 1 clamping assembly 31 and the No. 2 clamping assembly 32 respectively. After the bearing is fixed, the No. 2 rod 21 is controlled to gradually accelerate its rotation. The rotation of the No. 2 rod 21 drives the insert block 22 to rotate synchronously. The rotation of the insert block 22 drives the slider 313 and the No. 1 rod 312 to rotate. The rotation of the No. 1 rod 312 drives the No. 1 clamp 311 and the inner ring of the bearing to rotate. During the acceleration of the No. 2 rod 21, the slider 313 is accelerated synchronously. Since the slider 313 slides relative to the No. 1 rod 312, the slider 313 gradually slides radially away from the axis of the No. 1 rod 312 under the action of centrifugal force until The slider 313 is not in contact with the insert block 22. At this time, the No. 1 clamping component 31 is separated from the driving part 2. The No. 1 clamping component 31 and the inner ring of the bearing continue to rotate under the action of inertia. After the No. 1 clamping component 31 is separated from the driving part 2, the amplitude of the outer ring of the bearing can be detected by the No. 1 detection head 41. After the inner ring of the bearing stops rotating, the noise and state of the bearing can be evaluated by the waveform of the amplitude fed back by the No. 1 detection head 41, that is, the action of detecting the noise of the bearing is realized; by setting the No. 1 clamping component 31 that can be automatically separated from the driving part 2, the problem of the vibration generated by the driving part 2 itself during the detection process interfering with the detection result is avoided, so that the detection result is more accurate.

[0039] like Figure 1 , 2 As shown in Figure 3, the No. 2 clamping assembly 32 includes a connecting rod 321 and a No. 2 clamping jaw 322, the connecting rod 321 is fixedly mounted on the body 1, the No. 2 clamping jaw 322 includes a ring 3221 installed on the connecting rod 321 and a number of No. 1 telescopic rods 3222, the No. 1 clamping jaw 311 includes a disk 3111 and a number of No. 2 telescopic rods 3112, the No. 1 rod 312 is fixedly mounted on the disk 3111, and a number of No. 3 telescopic rods 5 are fixedly mounted on the body 1, and a placement plate 6 for placing bearings is fixedly mounted on the No. 3 telescopic rod 5.

[0040] Specifically, before work, the bearing is placed on the placement plate 6, and then the No. 3 telescopic rod 5 is controlled to extend upward until the bearing is located between the No. 1 clamp 311 and the No. 2 clamp 322, and then the No. 2 telescopic rod 3112 and the No. 1 telescopic rod 3222 of the No. 1 clamp 311 and the No. 2 clamp 322 are controlled to extend respectively to fix the inner ring and outer ring of the bearing respectively, thereby completing the action of fixing the bearing. Embodiment 2

[0041] like Figure 5 , 7 As shown in Figures 9, the driving unit 2 also includes a sticking plate 23 slidably mounted on the No. 2 rod 21. When the sticking plate 23 is in contact with the inner wall of the plug block 22, the plug block 22 is fixed on the No. 2 rod 21. When the sticking plate 23 is not in contact with the plug block 22, the plug block 22 can rotate relative to the No. 2 rod 21.

[0042] like Fig. 9 As shown, after the sticking plate 23 is no longer in contact with the inserting block 22 , the inserting block 22 is no longer in contact with the second rod 21 .

[0043] Specifically, the plug block 22 and the slider 313 are inseparable. In the initial state, the sticking plate 23 is in contact with the inner wall of the plug block 22. After the bearing is fixed, the No. 3 telescopic rod 5 is controlled to retract downward, driving the placement plate 6 to move downward synchronously, and the No. 2 rod 21 is controlled to accelerate rotation. The rotation of the No. 2 rod 21 drives the sticking plate 23 and the plug block 22 to rotate synchronously. The rotation of the plug block 22 drives the slider 313 and the No. 1 rod 312 to rotate. The rotation of the No. 1 rod 312 drives the No. 1 clamp 311 and the inner ring of the bearing to rotate synchronously. When the rotation speed of the inner ring of the bearing is faster, the sticking plate 23 is controlled to slide radially in the direction close to the axis of the No. 2 rod 21. At this time, the sticking plate 23 does not contact the inner wall of the plug block 22, and the plug block 2 2 and the slider 313 are separated from the second rod 21, that is, the first clamping assembly 31 and the inner ring of the bearing are separated from the second rod 21, and the second rod 21 is controlled to stop rotating, so that the first detection head 41 of the detection unit 4 can be controlled to detect the amplitude of the outer ring of the bearing. After the detection is completed, the control plate 23 is radially moved away from the axis of the second rod 21 until the plate 23 is in contact with the inner wall of the plug block 22. At this time, the first clamping assembly 31 is re-combined with the driving unit 2 through the plug block 22. After the detection is completed, there is no need to rotate the slider 313. After the slider 313 is aligned with the plug block 22, it is plugged in to realize the action of connecting the driving unit 2 and the first clamping assembly 31, which is more convenient to use.

[0044] There is no connection between the insert block 22 and the second rod 21, so when the bearing is tested, the insert block 22 and the first clamping assembly 31 are not in contact with the driving part 2, so the amplitude is not affected by the rotational friction between the first clamping assembly 31 and the driving part 2.

[0045] like Figure 1 , 4 As shown in , 5, 7, and 8, the driving part 2 also includes: a round block 24 rotatably mounted on the second rod 21, the sticking plate 23 is slidably connected with the round block 24, and the round block 24 can drive the sticking plate 23 to approach or move away from the plug block 22 after rotation; a ratchet 25 fixedly mounted on the round block 24, and the ratchet 25 is used to drive the round block 24 to rotate; a slide groove 26 provided on the second rod 21; a check block 27 slidably mounted in the slide groove 26, and when the check block 27 slides in the slide groove 26, it will slide radially relative to the axis of the ratchet 25; a push plate 215 rotatably mounted on the second rod 21, and the push plate 215 is used to push the check block 27 to slide in the slide groove 26;

[0046] A pull rod 28 fixedly mounted on the slider 313 , the pull rod 28 is used to drive the push plate 215 to rotate; and a torsion spring 29 mounted between the round block 24 and the second rod 21 .

[0047] Specifically, the check block 27 adopts a telescopic structure, and the check block 27 is used to limit the ratchet 25 to rotate only clockwise. In the initial state, the torsion spring 29 is in a torsion state, and the pull rod 28 is in contact with the push plate 215. In the process of the second rod 21 driving the plug block 22 and the slider 313 to rotate, the slider 313 slides relative to the plug block 22 under the action of centrifugal force, and the sliding of the slider 313 drives the pull rod 28 to move synchronously. The pull rod 28 drives the push plate 215 to rotate counterclockwise through the friction force. The push plate 215 rotates and pushes the check block 27 to slide in the slide groove 26 in the counterclockwise direction. While the check block 27 slides counterclockwise in the slide groove 26, it slides radially and horizontally in the direction away from the axis relative to the second rod 21 until the check block 27 is no longer in contact with the ratchet 25. At this time, the ratchet 25 rotates counterclockwise relative to the second rod 21 under the action of the elastic force of the torsion spring 29, and the rotation of the ratchet 25 drives the round block 24 to rotate synchronously. The rotation of the round block 24 causes the sticking plate 23 to rotate in a direction close to the The movement of the slider 313 makes the pull rod 28 move synchronously, and the pull rod 28 moves to push the push plate 215 to rotate clockwise, and the push plate 215 rotates clockwise, so that the check block 27 rotates clockwise. During the clockwise rotation of the check block 27, it moves toward the direction close to the axis of the No. 2 rod 21, so that the check block 27 contacts the ratchet 25 and pushes the ratchet 25 and the round block 24 to rotate clockwise. At this time, the torsion spring 29 is twisted, and there is no need to set up an additional detection device to detect the rotation speed of the No. 1 clamping assembly 31 and the inner ring of the bearing. When the rotation speed of the inner ring of the bearing is faster, the plate 23 can be automatically controlled to move away from the plug block 22, so that the No. 1 clamping assembly 31 and the driving part 2 are separated, saving costs.

[0048] like Figure 4 , 5 As shown in , 6, the driving part 2 also includes: a groove 210 opened on the sliding block 313; a push block 211 slidably installed on the groove 210; a No. 1 rotating rod 212 rotatably installed on the push block 211; a long rod 213 used to drive the No. 1 rotating rod 212 and the push block 211 to slide on the sliding block 313, the long rod 213 is slidably installed on the No. 1 rod 312, and one end of the No. 1 rotating rod 212 is rotatably installed on the long rod 213; a No. 2 rotating rod 214 used to drive the long rod 213 to slide up and down, one end of the No. 2 rotating rod 214 is rotatably installed on the long rod 213, and the other end of the No. 2 rotating rod 214 is rotatably installed on the movable end of the No. 2 telescopic rod 3112.

[0049] Specifically, when the second telescopic rod 3112 is extended, the second rotating rod 214 pulls the long rod 213 to move downward, and the long rod 213 moves downward, so that the first rotating rod 212 pushes the push block 211 to move in the groove 210 in the direction away from the second rod 21, so that the slider 313 can slide under the action of centrifugal force when rotating. Similarly, when the second telescopic rod 3112 is retracted, the first rotating rod 212 pulls the push block 211 to move in the groove 210 in the direction close to the second rod 21, and the push block 211 moves while pulling the slider 313 to move synchronously in the direction close to the second rod 21 until the slider 313 returns to its initial position, which is convenient to use.

[0050] like Figure 5 , 6 As shown, the contact surface between the slider 313 and the push block 211 is a smooth surface, and the contact surface between the insert block 22 and the slider 313 is a rough surface.

[0051] Specifically, the difference in surface roughness between the slider 313 and the push block 211 and the insert block 22 avoids the problem of synchronous movement of the slider 313 due to friction when the push block 211 slides in the groove 210 .

[0052] like Fig.10 As shown, the detection unit 4 further includes: a fourth telescopic rod 42 slidably mounted on the body 1;

[0053] A rotating block 43 rotatably mounted on the fourth telescopic rod 42 , wherein the first detection head 41 is mounted on one end of the rotating block 43 ; a round rod 44 is mounted up and down on the rotating block 43 ; and a switch 45 is mounted on the rotating block 43 , wherein the round rod 44 is used to trigger the switch 45 .

[0054] Specifically, by setting the round rod 44, when the No. 1 clamping assembly 31 and the inner ring of the bearing are driven by the No. 2 rod 21 to accelerate the rotation, the round rod 44 first contacts the outer ring of the bearing. If the amplitude of the outer ring of the bearing is large, the round rod 44 will move upward and trigger the switch 45. After the switch 45 is triggered, the detection can be stopped to avoid the problem of large amplitude of the bearing and damage to the No. 1 detection head 41.

[0055] like Figure 3 , 4 As shown, the detection unit 4 further includes a ring block 46 mounted on the machine body 1 , and a second detection head 47 is mounted on the ring block 46 .

[0056] Specifically, by providing the second detection head 47, the vibration of the bearing on the horizontal plane can be detected, so that the detection result is more detailed, which is convenient for analyzing the wear of the used bearing.

[0057] like Fig. 9 As shown, the second rotating rod 214 adopts a telescopic structure, and an insertion rod 7 for fixing the second rotating rod 214 is installed on the second rotating rod 214.

[0058] Specifically, by providing the insertion rod 7 and removing the insertion rod 7 during use, the first clamping assembly 31 and the driving part 2 can still be in a connected state during detection, that is, the device has two detection modes.

[0059] Working steps:

[0060] Step 1: Before working, place the bearing on the placement plate 6, then control the No. 3 telescopic rod 5 to extend upward until the bearing is located between the No. 1 clamp 311 and the No. 2 clamp 322, then control the No. 2 telescopic rod 3112 and the No. 1 telescopic rod 3222 of the No. 1 clamp 311 and the No. 2 clamp 322 to extend respectively, and fix the inner ring and outer ring of the bearing respectively, thus completing the action of fixing the bearing;

[0061] Step 2, after the bearing is fixed, control the No. 3 telescopic rod 5 to retract downward, drive the placement plate 6 to move downward synchronously, control the No. 2 rod 21 to accelerate rotation, the rotation of the No. 2 rod 21 drives the sticking plate 23 and the plug block 22 to rotate synchronously, the rotation of the plug block 22 drives the slider 313 and the No. 1 rod 312 to rotate, the rotation of the No. 1 rod 312 drives the No. 1 clamping claw 311 and the inner ring of the bearing to accelerate rotation synchronously, when the rotation speed of the inner ring of the bearing is faster, the slider 313 slides relative to the plug block 22 under the action of centrifugal force, the sliding of the slider 313 drives the pull rod 28 to move synchronously, the pull rod 28 drives the push plate 215 to rotate counterclockwise through friction, and the push plate 215 rotates to push the check block 27 to rotate counterclockwise The check block 27 slides in the slide groove 26 in the clockwise direction, and the check block 27 slides counterclockwise in the slide groove 26, and slides radially and horizontally relative to the No. 2 rod 21 in the direction away from the axis, until the check block 27 is no longer in contact with the ratchet 25. At this time, the ratchet 25 rotates counterclockwise relative to the No. 2 rod 21 under the elastic force of the torsion spring 29. The rotation of the ratchet 25 drives the round block 24 to rotate synchronously. The rotation of the round block 24 causes the plate 23 to move in the direction close to the axis of the No. 2 rod 21, so that the plate 23 is no longer in contact with the insert block 22, that is, the action of separating the No. 1 clamping assembly 31 from the No. 2 rod 21 is realized, and the No. 1 detection head 41 of the detection unit 4 can be controlled to detect the amplitude of the outer ring of the bearing.

[0062] Step three, after the detection is completed, push the slider 313 to move toward the direction close to the axis of the No. 2 rod 21. The movement of the slider 313 causes the pull rod 28 to move synchronously. The movement of the pull rod 28 pushes the push plate 215 to rotate clockwise. The push plate 215 rotates clockwise, causing the check block 27 to rotate clockwise. During the clockwise rotation of the check block 27, it moves toward the direction close to the axis of the No. 2 rod 21, causing the check block 27 to contact the ratchet 25 and push the ratchet 25 and the round block 24 to rotate clockwise. At this time, the torsion spring 29 is twisted, and the round block 24 rotates counterclockwise, causing the contact plate 23 to fit the inner wall of the insert block 22 again, so as to realize the action of connecting the drive unit 2 and the No. 1 clamping assembly 31.

[0063] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
