[0038] More specifically, the transmission shaft 4 at the lower part is provided with a mounting groove 41, a first connecting tube 42, a support rod 43 and a bearing plate 44.

When the bearing 9 to be detected is installed, the bearing 9 to be detected is placed on the supporting surface of the bearing plate 44, and then when the clamping tube 6 clamps the bearing 9 to be detected, the limited position surface on the second connecting plate 553 will abut against the end surface of the bearing 9 to be detected, thereby supporting and limiting the bearing 9 to be detected.

[0041] Specifically, the combination component 8 includes: a first tube 81, a second tube 82, a third tube 83, a mounting seat 84, a fourth electric push rod 85, a plug rod 86, a fourth tube 87 and a fifth tube 88. Since the support component 3, the transmission shaft 4, the drive component 5, the clamping tube 6, the clamping component 7 and the combination component 8 are set in two groups, one group is used to clamp the inner wall surface of the inner ring of the bearing, and the other group is used to clamp the outer wall surface of the outer ring of the bearing. For a clearer expression, the external support component 3, the external transmission shaft 4, the external drive component 5, the external clamping tube 6 and the external clamping component 7 represent a group for clamping the outer wall surface of the outer ring of the bearing 9 to be detected. The internal support component 3, the internal transmission shaft 4, the internal drive component 5, the internal clamping tube 6 and the internal clamping component 7 represent a group for clamping the inner wall surface of the inner ring of the bearing 9 to be detected. Among them, the clamping block 79 in the external clamping component 7 and the clamping block 79 in the internal clamping component 7 are provided with a connecting groove. The first tube 81 is inserted into the connecting groove on the clamping block 79 in the external clamping assembly 7, and the second tube 82 is inserted into the first tube 81, and the second tube 82 is slidably connected to the first tube 81.

The fifth tube 88 is inserted into the connecting groove in the external clamping block 79. The fourth tube 87 is inserted into the fifth tube 88, and the fourth tube 87 is slidably connected to the fifth tube 88. The insertion rod 86 is inserted into the fourth tube 87, and the insertion rod 86 is slidably connected to the fourth tube 87. A slot 841 whose shape matches the insertion rod 86 is formed on the mounting seat 84. The second tube 82 and the third tube 83 can slide outward relative to the first tube 81, thereby driving the mounting seat 84 away from the clamping block 79 in the external clamping assembly 7. The fourth tube 87 and the insertion rod 86 can slide outward relative to the fifth tube 88, thereby realizing that the insertion rod 86 is away from the clamping block 79 in the internal clamping assembly 7, and then the insertion rod 86 is inserted into the slot 841.

[0042] More specifically, the combination component 8 also includes: a glue dispensing robot, which is located at the fourth electric push rod 85 and adopts the existing technology. The output end of the fourth electric push rod 85 is a push rod that can be extended outward and retracted inward relative to the fourth electric push rod 85. After the insertion rod 86 is inserted into the slot 841, the glue dispensing robot performs a glue dispensing operation on the sealing cover on the bearing 9 to be tested, so that glue exists on the sealing cover, and then the fourth electric push rod 85 pushes the push rod outward, and the push rod abuts against the end face of the sealing ring, so that the push rod is fixed to the sealing cover through the glue, and then the fourth electric push rod 85 retracts the push rod, and the push rod pulls the sealing cover until the sealing cover is pulled open to the position where the sealing cover is separated from the bearing 9 to be tested. A tension sensor is provided at the fourth electric push rod 85, and the tension sensor is used to detect the tension required by the fourth electric push rod 85 to pull the sealing cover open to the position of being separated from the bearing 9 to be tested, and this tension is represented by real-time tension.

[0043] Specifically, the hinge ring 36 is fixedly connected to the first driving shaft 322, a receiving groove is formed in the hinge ring 36, the transmission shaft 4 is inserted into the receiving groove, the hinge rod 361 is fixedly installed on the transmission shaft 4, the hinge rod 361 is inserted into the receiving groove, the receiving groove wraps the hinge rod 361, so that the hinge rod 361 can slide and rotate in the receiving groove; thereby realizing the ball joint between the transmission shaft 4 and the first driving shaft 322.

[0044] Working process: first, place the bearing 9 to be tested on the supporting surface of the supporting plate 44, and then use the robotic arm 2 to move the upper and lower groups of supporting components 3, transmission shaft 4, driving component 5, clamping tube 6 and clamping component 7 close to each other, so that the bearing 9 to be tested is located between the upper and lower groups of supporting components 3, transmission shaft 4, driving component 5, clamping tube 6 and clamping component 7.

[0045] Then the first electric push rod 53 drives the transmission plate 52 to move, and the transmission plate 52 will move close to the third support plate 51. The transmission plate 52 drives the first connecting plate 551 to move through the third transmission connecting rod 54. The first connecting plate 551 is guided by the multi-section telescopic guide rod 57 to realize the movement of multiple first connecting plates 551 toward the axis of the transmission shaft 4. That is, the first connecting plate 551 drives the clamping tube 6 to move through the second connecting column 552 and the second connecting plate 553, thereby realizing the movement of multiple clamping tubes 6 close to the axis of the transmission shaft 4, and then the clamping tube 6 will contact the bearing.

[0046] To be precise, the first thing to do in the above movement is to move the lower support assembly 3, transmission shaft 4, drive assembly 5, clamping tube 6 and pressing assembly 7, and then the limiting surface of the second connecting plate 553 in the lower drive assembly 5 abuts against the lower end surface of the bearing 9 to be detected, thereby first supporting the lower surface of the bearing 9 to be detected and clamping the outer wall surface of the outer ring of the bearing 9 to be detected. Then the upper support assembly 3, transmission shaft 4, drive assembly 5, clamping tube 6 and pressing assembly 7 are moved, thereby clamping the inner wall surface of the inner inner ring of the bearing 9 to be detected. And due to the existence of the limiting surface on the second connecting plate 553, the inner ring and outer ring of the bearing 9 to be detected can be positioned and clamped respectively.

[0047] The third electric push rod 771 drives the flexible pull rope 77 to move, and the flexible pull rope 77 is stretched, so that the flexible pull rope 77 will pull the second piston plate 76 to move downward. The downward movement of the second piston plate 76 will compress the second pressure chamber 75, the suction chamber 74 is under negative pressure, and there is liquid in the second pressure chamber 75, preferably hydraulic oil. The compression of the second pressure chamber 75 will cause the hydraulic oil to reach the first pressure chamber 73 along the second connecting pipe 70, and then the pressure of the first pressure chamber 73 will increase, and the first pressure chamber 73 will push the first piston plate 72 to move downward, and the first piston plate 72 drives the fixed steel pipe 71 to move downward, and the fixed steel pipe 71 drives the pressing block 79 to move downward, so that the pressing block 79 will approach the end face of the bearing 9 to be detected until it abuts against the end face of the bearing 9 to be detected, so that the bearing 9 to be detected will be stuck by the pressing block 79 and the second connecting plate 553. Thereby, the inner ring of the bearing 9 to be detected and the outer ring of the bearing 9 to be detected are both fixed, and the bearing 9 to be detected cannot move.

[0048] The second driving motor 562 drives the transmission shaft 4 to rotate through the transmission belt structure 563, so that the transmission shaft 4 drives the third support plate 51 to rotate, thereby realizing the rotation of multiple clamping tubes 6 around the central axis of the transmission shaft 4. At this time, the upper driving assembly 5 can drive the inner ring of the bearing 9 to be detected to rotate clockwise, and the lower driving assembly 5 can drive the outer ring of the bearing 9 to be detected to rotate counterclockwise, thereby realizing that the inner ring and the outer ring of the bearing 9 to be detected rotate in different directions; it can also realize that the inner ring of the bearing 9 to be detected does not rotate, the outer ring of the bearing 9 to be detected rotates, and the outer ring of the bearing 9 to be detected does not rotate, and the inner ring of the bearing 9 to be detected rotates. Thereby, the use simulation of the bearing 9 to be detected is realized, and the motion state of the bearing 9 to be detected when in use is restored to a greater extent.

[0049] The load is applied to the bearing 9 to be tested through the support assembly 3 to simulate the load-bearing condition of the bearing 9 to be tested in actual use. Specifically, the first drive motor 321 drives the first drive shaft 322 to rotate, and the first drive shaft 322 drives the second drive shaft 341 to move, so that the second drive shaft 341 revolves, and then the second gear 332 on the second drive shaft 341 meshes with the first gear 331, and the second gear 332 is fixed, so that the second gear 332 can rotate on its own, so that the second drive shaft 341 can both rotate on its own and revolve on its own. The second driving shaft 341 drives the first transmission link 342 to move, the first transmission link 342 drives the second transmission link 343 to move, the second transmission link 343 drives the transmission rod 344 to move, the transmission rod 344 will drive the installation shell 351 to move, and the sliding block 352 is located in the sliding groove, so that the sliding block 352 is used to limit and guide the installation shell 351, so that the installation shell 351 can only slide under the restriction of the sliding block 352.

[0050] The sliding block 352 is fixed to the transmission shaft 4. The second driving shaft 341, the first transmission connecting rod 342, the second transmission connecting rod 343, the transmission rod 344 and the rib plate 345 form a crank slider structure, which will cause the mounting shell 351 to move continuously. The mounting shell 351 moves relative to the sliding block 352, so that the mounting shell 351 slides back and forth under the action of the slide groove and the sliding block 352, so that the elastic member 353 is compressed and uncompressed, and these two processes are continuously performed. When the elastic member 353 is compressed, the pressure sensor 354 can detect the change in the elastic force of the elastic member 353. First, the transmission ratio between the second gear 332 and the first gear 331 is relatively large, and you can refer to the attached figure Figure 3 . Then, the first drive motor 321 drives the first drive shaft 322 to rotate a smaller angle, which will realize the second drive shaft 341 to rotate one circle, so that the second drive shaft 341 will rotate one circle at one position, and the mounting shell 351 will move in one direction, so that the transmission shaft 4 is subjected to pressure at the sliding block 352, and the pressure is in one direction, which is defined as the first direction. Then, as the first drive motor 321 drives the first drive shaft 322 to rotate, the second drive shaft 341 will rotate one circle at different positions, and the transmission shaft 4 will also rotate, so that the transmission shaft 4 will be subjected to pressure in another direction, so that the transmission shaft 4 will be subjected to pressure in the second direction, the third direction... and the nth direction, so that the pressure sensor 354 will detect multiple pressure change values.

[0051] The upper support assembly 3 will perform pressure testing on the upper transmission shaft 4, and the lower support assembly 3 will perform pressure testing on the lower transmission shaft 4. The upper transmission shaft 4 matches the central axis of the inner ring of the bearing 9 to be tested, and the lower transmission shaft 4 matches the central axis of the outer ring of the bearing 9 to be tested. If there is an error in the size of the sphere of the bearing 9 to be tested and an error in the groove of the bearing 9 to be tested.

[0052] When there is an error in the size of the sphere of the bearing 9 to be tested, there will be a gap between the inner and outer rings of the bearing 9 to be tested at a certain point. When the bearing 9 to be tested is subjected to an external force, the inner and outer rings of the bearing 9 to be tested will be displaced relative to each other, that is, shaking will occur. Therefore, when a certain point of the bearing 9 to be tested is driven by an external force, the inner and outer rings will be displaced relative to each other. Then, the mounting shell 351 moves relative to the sliding block 352, and the mounting shell 351 moves relative to the sliding block 352 from different angles, that is, pressure is applied to the sliding block 352 through the elastic member 353. If the direction of the pressure is exactly located at the sphere with an error, the relationship between the displacement of the mounting shell 351 and the force of the elastic member 353 will be significantly different from that at other positions, so that it can be detected whether there is an obvious error in the size of the sphere of the bearing 9 to be tested, and the detection of the bearing 9 to be tested is realized. To be precise, it is because the transmission shaft 4 is ball-jointed with the first driving shaft 322 through the hinge ring 36, which makes one end of the transmission shaft 4 have the freedom of rotation. When there is an error in the sphere of the bearing 9 to be tested, the end of the transmission shaft 4 located at the driving component 5 will be fixed by the driving component 5 relative to the inner ring of the sphere, and the outer ring is also fixed, then there will be a relative displacement between the inner ring and the outer ring, which will cause the transmission shaft 4 to swing at a small angle, which will cause the relationship between the displacement of the mounting shell 351 and the force applied to the elastic member 353 to be significantly different from that at other positions.

[0053] When there is an error in the groove of the bearing 9 to be detected, the same phenomenon as when there is an error in the size of the sphere of the bearing 9 to be detected will occur, so that the error in the groove of the bearing 9 to be detected can also be detected.

[0054] In addition, the upper support assembly 3, transmission shaft 4, drive assembly 5, clamping tube 6 and clamping assembly 7 drive the inner ring of the bearing 9 to be tested to rotate, and the lower support assembly 3, transmission shaft 4, drive assembly 5, clamping tube 6 and clamping assembly 7 drive the outer ring of the bearing 9 to be tested to rotate. If there is a problem with the installation of the bearing 9 to be tested, the torque of the bearing 9 to be tested is too large. Since the rotation of the inner and outer rings of the bearing 9 to be tested is achieved by the hinged ring 36 mechanical arm 2 in the upper support assembly 3 and the hinged ring 36 mechanical arm 2 in the lower support assembly 3, the torque borne by the hinged ring 36 mechanical arm 2 can be detected by the formula T = the third transmission link 54 of the bearing 9 to be tested to be tested × P / n, and it can be directly known whether the torques of the two hinged rings 36 mechanical arms 2 are the same. If they are different, there is a problem with the installation. If the torque is too large, there is also a problem.

[0055] In addition, the sealing cover of the bearing 9 to be tested can also be tested. Since the sealing cover of the bearing 9 to be tested is used to seal the lubricating oil inside the bearing 9 to be tested, the sealing cover will be subjected to extrusion force during the operation of the bearing 9 to be tested. If the tensile force borne by the sealing cover is too small and it is pulled out, it means that the bearing 9 to be tested is unqualified. Therefore, a preset tensile force is set for the qualified bearing 9 to be tested. During the inspection, the sealing cover is first glued, and then the push rod of the fourth electric push rod 85 stands together with the sealing cover. The fourth electric push rod 85 retracts the push rod, and the real-time pulling force of the push rod to pull the sealing cover outward is detected to be greater than the preset pulling force. If the implemented pulling force is greater than the preset pulling force, the sealing cover is qualified.

[0056] The suction nozzle 61 is fixed to the clamping tube 6, and the suction nozzle 61 is connected to the suction chamber 74. The suction chamber 74 is connected to the outside through the suction nozzle 61. After the clamping tube 6 moves to contact the bearing 9 to be detected, the suction nozzle 61 is compressed, so that the suction nozzle 61 is close to the bearing 9 to be detected, so that the suction chamber 74 is sealed. Then the third electric push rod 771 pulls the clamping assembly 7 to move the second piston plate 76 downward, and the hydraulic oil in the second pressure chamber 75 reaches the first pressure chamber 73 through the second connecting pipe 70, so that the clamping block 79 is abutted against the end face of the bearing 9 to be detected. After the clamping block 79 abuts against the end face of the bearing 9 to be detected, the first piston plate 72 cannot continue to move downward, and then the second piston plate 76 continues to move downward to make the suction chamber 74 continue to have negative pressure, increase the adsorption force of the suction nozzle 61 and the bearing 9 to be detected, and better adsorb and fix the bearing 9 to be detected.

[0057] When the tensile strength of the sealing cover needs to be tested, the third electric push rod 771 continues to drive the clamping assembly 7 to move, so that the pressure valve 78 continues to move downward, thereby further increasing the pressure in the first pressure chamber 73. The pressure valve 78 adopts the existing technology. The function of the pressure valve 78 is to achieve pressure relief. When the pressure in the first pressure chamber 73 is not large, the hydraulic oil in the first pressure chamber 73 cannot reach the fixed steel pipe 71. When the pressure in the first pressure chamber 73 is too large, the hydraulic oil reaches the fixed steel pipe 71 through the pressure valve 78, and then the hydraulic oil reaches the combination assembly 8 along the fixed steel pipe 71. Thus, the hydraulic oil pushes the third tube 83, so that the third tube 83 moves toward the plug rod 86, and the plug rod 86 is close to the mounting seat 84, so that the plug rod 86 is inserted into the slot 841, so that the mounting seat 84 is supported and can withstand a larger load, so that the fourth electric push rod 85 can detect the tensile strength of the sealing cover more accurately.
