Description

Technical Field

[0001] The invention relates to the technical field of bearing flexibility detection, and in particular to a device for testing the flexibility of a suspended vehicle logo bearing. Background Art

[0002] With the development of the automobile industry, more and more cars are adopting floating logo designs to enhance the aesthetics and brand recognition of the vehicles. However, as a key component of support and connection, the flexibility of the floating logo bearing directly affects the movement stability and service life of the logo. Currently, the test of the flexibility of the floating logo bearing in the market mainly relies on manual observation and simple mechanical devices. This method is not only inefficient, but also difficult to accurately evaluate the performance changes of the bearing in long-term use. Therefore, there is an urgent need for a test equipment that can automatically and accurately measure the flexibility of the floating logo bearing.

[0003] However, there are usually some problems when testing the flexibility of bearings. With the development of science and technology, technicians in related fields have also made a lot of optimizations on the flexibility testing methods of bearings to solve some problems that different consumer groups are concerned about. In order to make a more accurate comparison, a Chinese patent with publication number CN105865790A discloses a bearing flexibility detection device and method; including a main controller, which is respectively connected to a photoelectric counting sensor, a speed sensor, an electric gripper, a drive mechanism and an electric push rod; the main controller is also connected to a wireless piezoelectric acceleration sensor through a wireless receiving device; when in use, the inner ring of the bearing to be tested is sleeved on the elastic part, and the main controller controls the electric gripper to clamp and fix the outer ring of the bearing to be tested; the inner ring of the bearing to be tested is driven to rotate through the elastic part; the rotation speed of the transmission shaft is obtained in real time through the speed sensor, and the main controller conducts a comprehensive analysis of the number of rotations and vibration information of the bearing to be tested to obtain the flexibility detection result of the bearing to be tested.

[0004] However, the above-mentioned prior art has some shortcomings in the actual use of bearing flexibility detection: 1. The bearing sleeve needs to be manually mounted on the elastic part before the electric gripper can fix the outer ring of the bearing. It is impossible to automatically transmit and clamp the bearing. The detection can only continue after one bearing is completed. The detection efficiency is low and batch detection of bearings is impossible.

[0005] 2. When it is necessary to test bearings of different diameters, the above-mentioned prior art cannot be adjusted according to the required diameters and sizes of different bearings, so that bearings of other diameters cannot be tested during the testing process. It has limitations and a small scope of application.

[0006] 3. Although the above-mentioned prior art can perform flexibility detection on bearings, it is unable to mark unqualified bearings after the detection is completed, making it difficult to distinguish qualified and unqualified bearings after the detection is completed, which is not convenient for subsequent sorting of bearings.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-Figure 9 Embodiments of the present invention are described in detail.

[0032] The embodiment of the present application discloses a device for testing the flexibility of a suspended car logo bearing. It should be noted that the device for testing the flexibility of a suspended car logo bearing of the present application is mainly used in the process of detecting the flexibility of the bearing. In terms of technical effect, it can automatically integrate internal support, transmission and detection, thereby realizing continuous detection of the bearing and greatly increasing the detection efficiency; in particular, it can adaptively shrink when internally supporting bearings of different inner diameters, so that the clamping rod 46 can internally support bearings of different inner diameters, greatly improving the scope of application of the present invention; further, the device for testing the flexibility of a suspended car logo bearing can also simulate the rotation amplitude of the bearing under the action of inertia after the car starts or stops moving, so that the detection process is more in line with actual use conditions, further improving the detection accuracy of the bearing of the present invention.

[0033] Example 1: Reference Figure 1As shown, a device for testing the flexibility of a suspended vehicle logo bearing comprises a bracket plate 1, a conveyor belt 12 is rotatably connected between two bracket plates 1, a base 2 is arranged on one side of the conveyor belt 12 along its length direction, a central axis 21 is mounted on the upper end of the base 2, a detection ring 22 is rotatably sleeved on the outer wall of the central axis 21, four groups of clamping units 4 are mounted on the outer wall of the detection ring 22, a receiving groove 23 is provided on the upper end of the detection ring 22, a bearing plate 24 is connected to the upper end of the central axis 21, a detection unit 6 is installed on the upper end of the bearing plate 24, the detection unit 6 is located at the upper end of the clamping unit 4, and a hopper 13 is commonly installed on one side of the two bracket plates 1 close to the detection unit 6; the hopper 13 is gradually inclined from top to bottom on both sides along the width direction, a material taking groove 14 is arranged on the side of the hopper 13 close to the detection unit 6, a discharging plate 15 is hinged on the side of the hopper 13 pointing to the rotation direction of the detection ring 22, and a torsion spring (not shown in the figure) is arranged at the hinge between the discharging plate 15 and the hopper 13.

[0034] It should be noted that the conveyor belt 12 in this embodiment is connected to an external motor (not shown in the figure), and the operation of the conveyor belt 12 can be controlled by starting the external motor; the torsion spring always applies a torsional force to the discharge plate 15 toward the side close to the receiving hopper 13, so that the discharge plate 15 is always in contact with the receiving hopper 13.

[0035] In the specific implementation process, the conveyor belt 12 is started, and the conveyor belt 12 conveys the bearing to be inspected to the side close to the central axis 21. Then, when the bearing is conveyed to the side of the hopper 13, the bearing falls into the hopper 13. During the falling process, the bearing gradually descends along the inclined surface of the hopper 13 to prevent the bearing from falling directly and colliding with the hopper 13, affecting its detection accuracy. When the bearing falls to the bottom of the hopper 13, the detection ring 22 is rotated 90°, and the clamping unit 4 is extended from the material trough 14 to support the inner ring of the bearing. Then, the detection ring 22 is rotated 90° again. During the rotation process, the detection ring 22 drives the bearing to move synchronously through the clamping unit 4. At the same time, the discharge plate 15 is rotated and opened under the push of the clamping unit 4, and the torsion spring is adaptively twisted. After the detection ring 22 completes its rotation, the discharge plate 15 is closed under the action of the torsion spring, and the clamping unit 4 drives the bearing to rotate to the bottom of the detection unit 6, so as to detect the flexibility of the bearing. After the detection is completed, the detection ring 22 is rotated 90° again to perform a second detection on the bearing. Finally, the detection ring 22 is rotated again to release the support on the bearing, and then the bearing that has been tested is taken out. During the rotation process, every time the detection ring 22 rotates 90°, a group of clamping units 4 close to the side of the conveyor belt 12 will internally support the bearing in the hopper 13, and detect the bearing through the detection unit 6 as the detection ring 22 rotates, thereby realizing automatic internal support, transmission and detection in one, realizing continuous detection of bearings, and greatly increasing detection efficiency.

[0036] Reference Figure 2 , Figure 3and Figure 4 As shown, in order to realize automatic transmission of bearings without manual transmission and detection, based on this, in the present embodiment, a driving motor 25 is installed on the upper end of the base 2, and the output shaft of the driving motor 25 is connected to the transmission shaft 26. The outer wall of the transmission shaft 26 is provided with a toggle rod 27, and the outer wall of the central shaft 21 is provided with a groove wheel 28. The upper end of the groove wheel 28 is provided with four toggle grooves 29 equidistantly distributed around the circumference, and a toggle block 30 sliding in the toggle groove 29 is installed on the side of the toggle rod 27 away from the transmission shaft 26; the outer wall of the central shaft 21 is provided with a cam 31 located in the accommodating groove 23, and the outer wall of the central shaft 21 is rotatably provided with a square plate 32 located at the upper end of the cam 31, and the upper end of the groove wheel 28 is connected to a connecting ring 33 rotatably provided on the outer wall of the central shaft 21, and the upper end of the connecting ring 33 is connected to the bottom of the detection ring 22.

[0037] Furthermore, in this embodiment, four sliding rods 34 are circumferentially equidistantly distributed on the outer wall of the detection ring 22, and the sliding rod 34 slides in contact with the cam 31 on the side close to the center axis 21, and a protrusion 35 is connected to the upper end of the sliding rod 34 on the side close to the center axis 21, and tension springs 36 are connected between the multiple protrusions 35 and the square plate 32, and the sliding rod 34 is connected to the clamping unit 4 on the side away from the center axis 21.

[0038] In a specific implementation process, the drive motor 25 is started, and the output shaft of the drive motor 25 drives the transmission shaft 26 to rotate, and then the transmission shaft 26 drives the toggle rod 27 to rotate. During the rotation of the toggle rod 27, the toggle groove wheel 28 is rotated 90° counterclockwise, and the toggle block 30 slides in the toggle groove 29. The groove wheel 28 rotates and drives the detection ring 22 to rotate through the connecting ring 33. During the rotation of the detection ring 22, the sliding rod 34 is driven to move circumferentially. During the movement of the sliding rod 34, the square plate 3 is driven through the protrusion 35 and the tension spring 36. 2 synchronously rotates and moves in a circumferential direction, and the sliding rod 34 always slides along the surface of the cam 31 under the action of the tension spring 36; when the sliding rod 34 on the groove side of the cam 31 rotates to the protruding side of the cam 31, the sliding rod 34 moves along the surface of the cam 31 to the side away from the central axis 21, and at the same time, the sliding rod 34 drives the protrusion 35 to move synchronously, and the tension spring 36 stretches adaptively, and the sliding rod 34 drives the clamping unit 4 connected thereto to extend into the material taking trough 14 and internally support the bearing, so as to facilitate the subsequent detection of the bearing.

[0039] When the toggle rod 27 rotates one circle, the toggle rod 27 drives the groove wheel 28 to rotate 90° again through the toggle block 30, and the groove wheel 28 drives the detection ring 22 to rotate through the connecting ring 33. The detection ring 22 drives the sliding rod 34, the protrusion 35, the tension spring 36 and the square plate 32 to move circumferentially as a whole. Therefore, every time the transmission shaft 26 drives the toggle rod 27 to rotate one circle, the groove wheel 28 drives the detection ring 22, the sliding rod 34 and the clamping unit 4 to rotate 90°.

[0040] When the sliding rod 34 rotates to the groove of the cam 31, the sliding rod 34 moves along the surface of the cam 31 to the side close to the central axis 21 under the tension of the tension spring 36, and drives the clamping unit 4 to move synchronously, so that the clamping unit 4 no longer provides internal support for the bearing, thereby facilitating the removal of the bearing after inspection, realizing automatic transmission during the bearing inspection process, eliminating the need for manual transportation and inspection, saving labor costs, and improving work efficiency.

[0041] Reference Figure 2 , Figure 5 and Figure 6 As shown, in order to realize automatic internal support fixation and release of the bearing, based on this, a clamping unit 4 is provided in this embodiment; specifically, the clamping unit 4 includes a matching gear 41 sleeved on the outer wall of the sliding rod 34 away from the central axis 21, and the matching gear 41 is connected to a limit ring 42 on the side away from the central axis 21 through a plurality of connecting rods, and the limit ring 42 is circumferentially provided with a plurality of sliding grooves 43 at equal intervals on the side away from the central axis 21, and a sliding block 44 is slidably connected in the sliding groove 43, and the sliding block 44 gradually moves away from the central axis 21 on the side close to the axis of the limit ring 42. 1, a compression spring 45 is connected between the sliding groove 43 and the sliding block 44 on the side away from the axis of the limiting ring 42, and a clamping rod 46 is connected to the sliding block 44 on the side away from the central axis 21; a linkage groove 47 is arranged inside the sliding rod 34, and a through hole 48 is opened on the side away from the central axis 21 of the linkage groove 47, and a trigger rod 49 is slidably connected in the through hole 48, and a trigger block 50 located on the opposite side of the plurality of sliding blocks 44 is sleeved on the outer wall of the trigger rod 49, and the radius of the trigger block 50 on the side away from the central axis 21 gradually increases, and the sliding rod 34 is located in the middle of the limiting ring 42.

[0042] Furthermore, in the present embodiment, a linkage block 51 is installed at the upper end of the trigger rod 49, a trigger groove 52 is provided at the upper end of the linkage block 51, a clamping block 53 is slidably connected in the trigger groove 52, the upper end of the clamping block 53 is hemispherical, a trigger spring 54 is connected between the bottom of the clamping block 53 and the inner bottom wall of the trigger groove 52, a clamping hole 55 which gradually shrinks from bottom to top is provided on the inner wall of the trigger groove 52, a reset spring 56 is connected between the linkage groove 47 and the trigger rod 49 on the side close to the central axis 21, and a plurality of trigger rings 57 which are respectively sleeved on the outer walls of the sliding rod 34 are connected to the outer wall of the detection ring 22.

[0043] It should be noted that the extrusion spring 45 always applies an elastic force to the sliding block 44 toward the side close to the trigger rod 49, so that the sliding block 44 returns to its original position after losing the limit of the trigger block 50; the return spring 56 always applies an elastic force to the trigger rod 49 toward the side away from the central axis 21, so that the trigger rod 49 returns to its original position after losing the limit of the clamping block 53.

[0044] In the specific implementation process, when the sliding rod 34 moves circumferentially to the side close to the material receiving bucket 13, the sliding rod 34 moves to the side away from the central axis 21, and the sliding rod 34 drives the clamping rod 46 and the trigger rod 49 to move synchronously and move to the middle of the bearing. When the trigger rod 49 contacts the material receiving bucket 13, the trigger rod 49 cannot move under the limit of the material receiving bucket 13. Then the trigger rod 49 moves into the linkage groove 47 and drives the trigger block 50 to move synchronously. The reset spring 56 shrinks adaptively, and the sliding block 44 is squeezed during the movement of the trigger block 50. The sliding block 44 moves to the side along the sliding groove 43 away from the axis of the limit ring 42 under the squeezing of the trigger block 50, and the squeezing spring 45 shrinks adaptively, and the sliding block 44 synchronously drives the clamping rod 46 to move during the movement, so that the clamping rod 46 supports the inner wall of the bearing.

[0045] At the same time, the trigger rod 49 drives the linkage block 51 to move synchronously during its movement, and the linkage block 51 drives the clamping block 53 and the trigger spring 54 to move synchronously during its movement. When the clamping block 53 moves to the clamping hole 55, the clamping block 53 enters the clamping hole 55 along the inclined surface of the clamping hole 55 under the action of the trigger spring 54, thereby preventing the trigger rod 49 from being reset under the action of the reset spring 56, causing the clamping rod 46 to be unable to continue to support the bearing internally; in addition, by squeezing the spring 45, it can adaptively shrink when supporting bearings with different inner diameters, so that the clamping rod 46 can support bearings with different inner diameters internally, which greatly improves the scope of application of the present invention.

[0046] When the sliding rod 34 moves circumferentially to the groove of the cam 31, the sliding rod 34 moves toward the side close to the central axis 21. During the movement of the sliding rod 34, the trigger ring 57 slides along its outer wall. When the sliding rod 34 drives the clamping block 53 to move synchronously, the clamping block 53 contacts the triggering ring 57. Because the top of the clamping block 53 is hemispherical, the clamping block 53 shrinks into the linkage groove 47 under the extrusion of the triggering ring 57, and the triggering spring 54 shrinks adaptively, so that the trigger rod 49 loses the limit of the clamping block 53. The trigger rod 49 moves to the side away from the central axis 21 under the elastic force of the reset spring 56. The trigger rod 49 drives the trigger block 50 to move synchronously, so that the trigger block 50 no longer squeezes the sliding block 44. The sliding block 44 moves along the sliding groove 43 toward the axis of the limiting ring 42 under the action of the extrusion spring 45. The sliding block 44 drives the clamping rod 46 to move synchronously, so that the clamping rod 46 no longer supports the inner wall of the bearing, thereby facilitating the removal of the bearing after the detection is completed.

[0047] Reference Figure 2 and Figure 7As shown, in order to mark unqualified bearings during the bearing detection process, a detection unit 6 is provided in this embodiment; specifically, the detection unit 6 includes a first bending rod 69 installed on the upper end of the bearing plate 24, and a first spring rod 70 is installed at the bottom of the first bending rod 69 away from the central axis 21. Two first support rods 71 ​​are installed at the bottom of the first spring rod 70, and a first detection wheel 72 is rotatably connected between the two first support rods 71. A plurality of first seals 73 close to the top are installed on the outer wall of the first detection wheel 72, and a first counterweight block 74 is installed at the bottom of the first detection wheel 72.

[0048] It should be noted that the first counterweight 74 always applies downward gravity to the first detection wheel 72 , so that the first detection wheel 72 can be reset under the action of the gravity of the first counterweight 74 after rotating.

[0049] In the specific implementation process, when the clamping rod 46 drives the bearing to move below the first detection wheel 72, the outer ring of the bearing contacts the first detection wheel 72, and the matching gear 41 meshes with the linkage gear 68. During the rotation of the transmission shaft 26, the transmission shaft 26 drives the transmission gear 61 to rotate, and the transmission gear 61 drives the speed-increasing gear 62 to rotate. The speed-increasing gear 62 drives the first bevel gear 64 to rotate through the sleeve ring 63, and the first bevel gear 64 drives the second bevel gear 67 to rotate. During the rotation of the second bevel gear 67, the linkage shaft 66 and the linkage gear 68 are driven to rotate synchronously, so that during the rotation of the linkage gear 68, the matching gear 41 is driven to rotate, and the matching gear 41 drives the limit ring 42, the sliding block 44 and the clamping rod 46 to rotate synchronously through the connecting rod; the clamping rod 46 rotates During the rotation of the first detection wheel 72, the first seal 73 on its outer wall will print a mark on the outer ring of the bearing, thereby realizing the flexibility detection of the bearing and marking the unqualified bearings for subsequent screening; when the clamping rod 46 drives the bearing to move and move away from the first detection wheel 72, the first detection wheel 72 is reset under the action of the first counterweight block 74, so as to continue to detect the next transmitted bearing, thereby realizing batch detection of bearings.

[0050] Example 2: Reference Figure 8 and Fig. 9As shown, on the basis of embodiment one, in order to be able to better detect the bearing and improve the detection accuracy of the bearing flexibility, based on this, in this embodiment, a telescopic rod 75 is connected between the central axis 21 and the supporting plate 24, and a second bending rod 76 distributed vertically with the first bending rod 69 is installed on the upper end of the supporting plate 24, and two second support rods 78 are connected to the bottom of the second bending rod 76 through a second spring rod 77, and a second detection wheel 79 is rotatably connected between the two second support rods 78, and a plurality of second seals 80 are installed on the outer wall of the second detection wheel 79, and a second counterweight block 81 is installed on the outer wall of the second detection wheel 79 near the bottom.

[0051] It should be noted that the second spring rod 77 always applies a downward elastic force to the second detection wheel 79, so as to ensure that when the bearing moves to the bottom of the second detection wheel 79, the second detection wheel 79 always fits against the outer wall of the bearing.

[0052] In the specific implementation process, during the detection of bearings of different diameters, the telescopic length of the telescopic rod 75 is adjusted to make the height of the first bending rod 69 and the second bending rod 76 rise or fall, thereby ensuring that the bearing can fit with the first detection wheel 72 and the second detection wheel 79 when it moves to the bottom of the first detection wheel 72 and the second detection wheel 79, further improving the scope of application of the present invention; in addition, after the bearing rotates to the side close to the linkage gear 68 to complete the detection, the detection ring 22 rotates again and drives the bearing to rotate synchronously through the clamping rod 46. At this time, the matching gear 41 is no longer meshed with the linkage gear 68, and the matching gear 41 no longer rotates, and the inner ring of the bearing cannot continue to rotate under the limitation of the clamping rod 46. The inertia generated by the bearing during the previous rotation process causes the outer ring of the bearing to rotate. When the outer ring of the bearing rotates to the bottom of the second detection wheel 79 and contacts it, the rotation of the bearing simultaneously drives the second detection wheel 79 to rotate synchronously. Therefore, if the rotation amplitude of the outer ring of the bearing is large, the second seal 80 prints a mark on the outer ring of the bearing during the rotation of the second detection wheel 79, simulating the rotation amplitude detection of the bearing under the action of inertia after the car starts or stops moving, so that the detection process is more in line with the actual use conditions, and the detection accuracy of the bearing of the present invention is further improved.

[0053] During operation: Step 1: Start the conveyor belt 12. The conveyor belt 12 conveys the bearing to be inspected to the side close to the central axis 21. Then, when the bearing is conveyed to the side of the hopper 13, the bearing falls into the hopper 13. During the falling process, the bearing gradually descends along the inclined surface of the hopper 13 to prevent the bearing from falling directly and colliding with the hopper 13, affecting its detection accuracy. When the bearing descends to the bottom of the hopper 13, the detection ring 22 is rotated 90°, and the clamping unit 4 is extended from the material trough 14 to support the inner ring of the bearing. Then, the detection ring 22 is rotated 90° again. During the rotation process, the detection ring 22 drives the bearing to move synchronously through the clamping unit 4. At the same time, the discharge plate 15 is rotated and opened under the push of the clamping unit 4, and the torsion spring is adaptively retracted. After the rotation is completed, the discharge plate 15 is closed under the action of the torsion spring.

[0054] The second step: start the driving motor 25, the output shaft of the driving motor 25 drives the transmission shaft 26 to rotate, and then the transmission shaft 26 drives the toggle rod 27 to rotate. During the rotation of the toggle rod 27, the toggle groove wheel 28 rotates 90° counterclockwise, and the toggle block 30 slides in the toggle groove. The groove wheel 28 rotates and drives the detection ring 22 to rotate through the connecting ring 33. During the rotation of the detection ring 22, the sliding rod 34 is driven to move circumferentially. During the movement of the sliding rod 34, the square plate 32 is driven to move synchronously circumferentially through the protrusion 35 and the tension spring 36. The sliding rod 34 always slides along the surface of the cam 31 under the action of the tension spring 36; when the sliding rod 34 on the groove side of the cam 31 rotates to the protruding side of the cam 31, the sliding rod 34 moves along the surface of the cam 31 to the side away from the central axis 21, and the sliding rod 34 drives the protrusion 35 to move synchronously, and the tension spring 36 stretches adaptively. The sliding rod 34 drives the clamping unit 4 connected to it to extend into the material trough 14 and internally support the bearing, so as to facilitate the subsequent detection of the bearing.

[0055] When the toggle rod 27 rotates one circle, the toggle rod 27 rotates the toggle groove wheel 28 90° through the toggle block 30, and the groove wheel 28 drives the detection ring 22 to rotate through the connecting ring 33. The detection ring 22 drives the sliding rod 34, the protrusion 35, the tension spring 36 and the square plate 32 to move circumferentially as a whole. Therefore, every time the transmission shaft 26 drives the toggle rod 27 to rotate one circle, the groove wheel 28 drives the detection ring 22, the sliding rod 34 and the clamping unit 4 to rotate 90°.

[0056] When the sliding rod 34 moves circumferentially to the groove of the cam 31, the sliding rod 34 moves along the surface of the cam 31 toward the side close to the central axis 21 under the tension of the tension spring 36, and drives the clamping unit 4 to move synchronously, so that the clamping unit 4 no longer provides internal support for the bearing, thereby facilitating the removal of the bearing after inspection, realizing automatic transmission during the bearing inspection process, eliminating the need for manual transportation and inspection, saving labor costs, and improving work efficiency.

[0057] Step 3: When the sliding rod 34 moves circumferentially to the side close to the material receiving hopper 13, the sliding rod 34 moves to the side away from the central axis 21, and the sliding rod 34 drives the clamping rod 46 and the trigger rod 49 to move synchronously and move to the middle of the bearing. When the trigger rod 49 contacts the material receiving hopper 13, the trigger rod 49 cannot move due to the limit of the material receiving hopper 13. Then the trigger rod 49 moves into the linkage groove 47 and drives the trigger block 50 to move synchronously. The reset spring 56 shrinks adaptively, and the trigger block 50 squeezes the sliding block 44 during the movement. The sliding block 44 moves to the side along the sliding groove 43 away from the axis of the limiting ring 42 under the squeezing of the trigger block 50. The squeezing spring 45 shrinks adaptively, and the sliding block 44 synchronously drives the clamping rod 46 to move during the movement, so that the clamping rod 46 supports the inner wall of the bearing.

[0058] At the same time, the trigger rod 49 drives the linkage block 51 to move synchronously during its movement, and the linkage block 51 drives the clamping block 53 and the trigger spring 54 to move synchronously during its movement. When the clamping block 53 moves to the clamping hole 55, the clamping block 53 enters the clamping hole 55 along the inclined surface of the clamping hole 55 under the action of the trigger spring 54, thereby preventing the trigger rod 49 from being reset under the action of the reset spring 56, causing the clamping rod 46 to be unable to continue to support the bearing internally; in addition, by squeezing the spring 45, it can adaptively shrink when supporting bearings with different inner diameters, so that the clamping rod 46 can support bearings with different inner diameters internally, which greatly improves the scope of application of the present invention.

[0059] When the sliding rod 34 rotates to the groove of the cam 31, the sliding rod 34 moves toward the side close to the central axis 21. During the movement of the sliding rod 34, the trigger ring 57 slides along its outer wall. When the sliding rod 34 drives the clamping block 53 to move synchronously, the clamping block 53 contacts the triggering ring 57. Because the top of the clamping block 53 is hemispherical, the clamping block 53 shrinks into the linkage groove 47 under the extrusion of the triggering ring 57, and the triggering spring 54 shrinks adaptively, so that the trigger rod 49 loses the limit of the clamping block 53. The trigger rod 49 moves to the side away from the central axis 21 under the elastic force of the reset spring 56. The trigger rod 49 drives the trigger block 50 to move synchronously, so that the trigger block 50 no longer squeezes the sliding block 44. The sliding block 44 moves along the sliding groove 43 toward the axis of the limiting ring 42 under the action of the extrusion spring 45. The sliding block 44 drives the clamping rod 46 to move synchronously, so that the clamping rod 46 no longer supports the inner wall of the bearing, thereby facilitating the removal of the bearing after the detection is completed.

[0060] Step 4: When the clamping rod 46 drives the bearing to move below the first detection wheel 72, the outer ring of the bearing contacts the first detection wheel 72, and the matching gear 41 meshes with the linkage gear 68. During the rotation of the transmission shaft 26, the transmission shaft 26 drives the transmission gear 61 to rotate, and the transmission gear 61 drives the speed-increasing gear 62 to rotate. The speed-increasing gear 62 drives the first bevel gear 64 to rotate through the sleeve ring 63, and the first bevel gear 64 drives the second bevel gear 67 to rotate. During the rotation of the second bevel gear 67, the linkage shaft 66 and the linkage gear 68 are driven to rotate synchronously, so that during the rotation of the linkage gear 68, the matching gear 41 is driven to rotate, and the matching gear 41 drives the limit ring 42, the sliding block 44 and the clamping rod 46 to rotate synchronously through the connecting rod; during the rotation of the clamping rod 46, the matching gear 41 drives the limit ring 42, the sliding block 44 and the clamping rod 46 to rotate synchronously. The inner ring of the dynamic bearing rotates. If the bearing has high flexibility, its outer ring will not rotate or will rotate slightly during the rotation of the inner ring of the bearing. If the bearing has low flexibility, the outer ring of the bearing will rotate significantly during the rotation of the inner ring of the bearing. At this time, the first detection wheel 72 in contact with the outer wall of the bearing rotates synchronously due to the driving force of the outer ring of the bearing. During the rotation of the first detection wheel 72, the first seal 73 on its outer wall will print a mark on the outer ring of the bearing, thereby realizing the flexibility detection of the bearing and marking unqualified bearings for subsequent screening. When the clamping rod 46 drives the bearing to move and move away from the first detection wheel 72, the first detection wheel 72 is reset under the action of the first counterweight block 74, so as to continue to detect the next transmitted bearing, thereby realizing batch detection of bearings.

[0061] Step 5: In the process of testing bearings of different diameters, the telescopic length of the telescopic rod 75 is adjusted to make the height of the first bending rod 69 and the second bending rod 76 rise or fall, thereby ensuring that the bearing can fit with the first detection wheel 72 and the second detection wheel 79 when it moves to the bottom of the first detection wheel 72 and the second detection wheel 79, further improving the scope of application of the present invention; in addition, after the bearing rotates to the side close to the linkage gear 68 to complete the detection, the detection ring 22 rotates again and drives the bearing to rotate synchronously through the clamping rod 46. At this time, the matching gear 41 is no longer meshed with the linkage gear 68, and the matching gear 41 is not The inertia generated by the bearing during the previous rotation process causes the outer ring of the bearing to rotate. When the outer ring of the bearing rotates to the bottom of the second detection wheel 79 and contacts it, the rotation of the bearing drives the second detection wheel 79 to rotate synchronously. Therefore, if the rotation amplitude of the outer ring of the bearing is large, the second seal 80 prints a mark on the outer ring of the bearing during the rotation of the second detection wheel 79, simulating the rotation amplitude detection of the bearing under the action of inertia after the car starts or stops moving, so that the detection process is more in line with the actual use conditions, and the detection accuracy of the bearing of the present invention is further improved.

[0062] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
