The two electric sliders 14 can move back and forth inside the corresponding arc grooves 8, and drive the rectangular frame 6 to make circular motion; a first driving device is preset inside one of the electric sliders 14, and the output end of the first driving device is connected to one of the rotating shafts, so as to drive the rectangular frame 6 to make circular motion with the rotating shaft as the center.

[0038] As a technical optimization solution of the present invention, mounting frames 15 are installed at both upper and lower ends of the rectangular frame 6, and telescopic cylinders 16 are installed inside the two mounting frames 15.

[0040] As a technical optimization solution of the present invention, the cross section of the monitoring station body 1 is trapezoidal, and two guide plates 5 are symmetrically installed on the inclined surfaces on both sides of the top of the monitoring station body 1. The two sets of guide plates 5 arranged on the top of the monitoring station body 1 can assist in guiding the unloading of the tested bearing body 7, and collection boxes for collecting qualified bearing bodies 7 and unqualified bearing bodies 7 are respectively placed at both ends of the bottom of the monitoring station body 1, so as to facilitate the classified collection and storage of the tested bearing bodies 7.

[0041] As a technical optimization scheme of the present invention, the auxiliary installation mechanism includes a rectangular groove 29 opened inside the two extrusion blocks 17, and double-headed screws 32 are rotatably installed inside the two rectangular grooves 29. Two movable plates 36 are symmetrically installed on the outer walls of the two double-headed screws 32. Connecting rods 33 are rotatably installed at both ends of the two movable plates 36. The outer walls of both sides of the two extrusion blocks 17 are provided with movable frames 31, and the ends of the two connecting rods 33 away from the movable plates 36 are respectively hinged to the movable frames 31 close to them. A third driving device is preset inside the two extrusion blocks 17, and the output end of the third driving device is connected to one end of the double-headed screw 32, so that the double-headed screw 32 can be driven to rotate inside the rectangular groove 29, thereby driving the two movable plates 36 to move in a direction of approaching or moving away from each other; in the process of the two movable plates 36 moving in the direction of approaching, the connecting rods 33 at both ends of the two movable plates 36 are driven to rotate in the direction of approaching, and the two movable frames 31 are pushed to move in the direction away from the extrusion block 17; in the process of the two movable plates 36 moving in the direction of moving away, the connecting rods 33 at both ends of the two movable plates 36 are driven to rotate in the direction of moving away, and the two movable frames 31 are pulled to move in the direction close to the extrusion block 17, so as to achieve the effect of adjusting the distance between the two movable frames 31 and the extrusion block 17.

[0042] As a technical optimization solution of the present invention, two second slide grooves 34 are provided on the outer wall of the two moving frames 31 on the side away from each other, and second sliders 35 are installed inside the two second slide grooves 34. A rectangular plate 18 is provided on the outer wall of the two moving frames 31 on the side away from each other, and one end of the two second sliders 35 away from the second slide groove 34 is respectively connected to the rectangular plate 18 close to it. A linear motor is preset inside the two second slide grooves 34, and the linear motor can drive the second slider 35 to move up and down inside the second slide groove 34, and drive the two rectangular plates 18 to move up and down on the corresponding outer wall of the moving frame 31.

[0043] As a technical optimization solution of the present invention, a rubber pad 30 is installed at one end of the two rectangular plates 18 that are close to each other, and an arc-shaped opening that is compatible with the outer wall of the telescopic end of the first electric telescopic rod 10 is opened at the other end of the two rectangular plates 18 that are close to each other. Rubber sealing strips 21 that are used in conjunction with the two rectangular plates 18 are installed at the four corner positions of the outer wall on one side where the two extrusion blocks 17 are close to each other, and two second shielding cloths 20 are symmetrically installed between the two extrusion blocks 17. Since two of the rectangular plates 18 are far away from the drive motor 9, and the bearing body 7 is installed from the end away from the drive motor 9, when the bearing body 7 needs to be installed on the surface of the clamping mechanism, two of the rectangular plates 18 can be moved in a direction close to each other, so that the rubber pads 30 on the close side of the two rectangular plates 18 can clamp and fix the circular outer wall of the bearing body 7; the other two rectangular plates 18 are located close to the drive motor 9 and the first electric telescopic rod 10. When the two rectangular plates 18 move in a direction close to each other, the arc-shaped opening can be used to abut and cooperate with the outer wall of the first electric telescopic rod 10 to seal the bearing body 7 inside the rectangular frame 6.

[0044] As a technical optimization solution of the present invention, the outer walls of the two rectangular plates 18 are both installed with connecting ends 23 for connecting with an external preset oil delivery mechanism, and the inner walls of the two rectangular plates 18 are both provided with oil outlets 37 for discharging lubricating oil. The output end of the external preset oil delivery mechanism can be connected to the connecting end 23 through a hose, and the center position of the two rectangular plates 18 is hollow, so that the lubricating oil delivered by the external oil delivery mechanism can enter the cavity through the connecting end 23 and be discharged to the surface of the bearing body 7 through the oil outlet 37. As the bearing body 7 continues to rotate, the bearing body 7 can be detected by means of an oil detection method. By sampling and analyzing the lubricating oil around the bearing body 7, it can be determined whether there are metal particles, wear powder, moisture or other contaminants in the bearing body 7. Normal lubricating oil should be clean and transparent, while abnormal oil may be caused by a fault in the bearing body 7. Oil testing can detect early signs of failure of the bearing body 7 and ensure the normal operation of the subsequent bearing body 7 during actual use; the second shielding cloth 20 arranged between the two extrusion blocks 17 can prevent the lubricating oil with impurities from directly entering the guide groove, and the first shielding cloth 27 arranged on the outer walls on both sides of the two first sliding blocks 28 can prevent the lubricating oil with impurities from directly entering the first slide groove 22, and can filter the excess lubricating oil with the help of the first shielding cloth 27 and the second shielding cloth 20, so that the filtered lubricating oil can lubricate the inner wall of the guide groove and the first slide groove 22, thereby reducing the waste of excess lubricating oil during the test.

[0045] In the present invention, when it is necessary to perform a pressure test on the bearing body 7, the double-headed screws 32 inside the two extrusion blocks 17 can be controlled to rotate, driving the two moving plates 36 to move in a direction close to each other, and the two sets of corresponding connecting rods 33 are used to push the two rectangular plates 18 to move and extend in a direction away from each other, so that two of the rectangular plates 18 move in a direction away from the drive motor 9, and the other two rectangular plates 18 move in a direction close to the drive motor 9. At this time, the other two rectangular plates 18 can be controlled to move in a direction close to each other until the arc-shaped openings at one end of the other two rectangular plates 18 are tightly abutted against the outer wall of the first electric telescopic rod 10, ensuring that the first electric telescopic rod 10 and the round block 11 at its telescopic end are in a horizontal straight line state. The bearing body 7 is placed between two of the rectangular plates 18 manually or with the help of a preset manipulator, and the two rectangular plates 18 are moved in a direction close to each other to clamp the bearing body 7. As the two double-headed screws 32 are controlled to reverse, the two rectangular plates 18 and the clamped bearing body 7 are driven to move together in a direction close to the extrusion block 17, so that the two rectangular plates 18 can drive the bearing body 7 to automatically move between the two extrusion blocks 17 at this time, achieving the effect of automatic loading and installation, avoiding the problem of manually placing the bearing body 7 directly between the two extrusion blocks 17 and accidentally touching the switches of the two telescopic cylinders 16, which may cause harm to the staff, thereby improving the safety of the installation of the bearing body 7.

[0046] After the bearing body 7 is placed between the two extrusion blocks 17, the telescopic ends of the two telescopic cylinders 16 are extended together, driving the two extrusion blocks 17 to squeeze the bearing body 7, and testing the force or pressure that the bearing body 7 bears in a static state to determine its load-bearing capacity, thereby achieving the effect of pressure testing the bearing body 7.

[0047] After the two extrusion blocks 17 complete the pressure test on the bearing body 7, the telescopic end of the first electric telescopic rod 10 is controlled to extend, driving the round block 11 and multiple clamping plates 12 to be inserted into the interior of the bearing body 7, and the telescopic ends of multiple groups of second electric telescopic rods 13 are controlled to extend together, driving the multiple clamping plates 12 to closely abut against the inner wall of the bearing body 7, so as to achieve the effect of automatically clamping and fixing the bearing body 7, which is convenient for subsequent testing of the bearing body 7.

[0048] After the bearing body 7 is clamped and fixed by the clamping mechanism, the telescopic ends of the two telescopic cylinders 16 can be controlled to retract, and the two extrusion blocks 17 can be driven to move in directions away from each other, and then the two first sliders 28 inside the two first slide grooves 22 can be controlled to move in directions close to each other, and then the telescopic ends of the two telescopic cylinders 16 can be controlled to extend in turn, and the two extrusion blocks 17 can be driven to move in directions close to the bearing body 7 in turn, so that after the two vibration sensors 24 abut against the outer wall of the bearing body 7, the driving motor 9 drives the clamping mechanism and the bearing body 7 to rotate synchronously, and the vibration generated during the rotation of the bearing body 7 is monitored and analyzed in real time. A normal bearing body 7 should have regular vibrations during operation, while abnormal vibrations may be caused by a fault in the bearing body 7 itself. Vibration detection can detect the fault of the bearing body 7 in advance, and judge the type and degree of the fault of the bearing body 7 according to the characteristics of the vibration signal.

[0049] After the two noise sensors 25 are moved to a position close to the bearing body 7, they analyze and judge the noise generated by the bearing body 7 during operation. A normal bearing body 7 should not have obvious noise during operation, while abnormal noise may be caused by a fault in the bearing body 7. Noise detection can detect the fault of the bearing body 7 early and take corresponding maintenance measures to avoid failures and accidents after the bearing body 7 is put into use.

[0050] After the vibration and noise of the bearing body 7 are detected, the two first sliders 28 in the two first slide grooves 22 are controlled to move and reset in the directions away from each other, and the vibration sensors 24 and noise sensors 25 in the two groups of moving blocks 19 are controlled to shrink inside the moving blocks 19, and then the multiple cover plates 26 are controlled to rotate and reset, so as to protect the vibration sensors 24 and noise sensors 25 in the two groups of moving blocks 19 in the shrinking state. Then, the two first sliders 28 in the two first slide grooves 22 are controlled to move in the directions close to each other, so as to drive the two groups of moving blocks 19 to have a clamping and limiting effect on both sides of the bearing body 7 respectively, so that the two groups of matching moving blocks 19 can limit and fix the outer ring of the bearing body 7 at this time, simulating the use state of the bearing body 7 inside the motor housing, and then the telescopic ends of the two telescopic cylinders 16 are controlled to extend together, so as to drive the two extrusion blocks 17 to squeeze the bearing body 7 whose inner ring is in the rotating state again, and test the force or pressure borne by the bearing body 7 in the moving state to evaluate its bearing capacity, so as to be closer to the actual working conditions of the bearing body 7, and make the pressure test of the bearing body 7 more accurate.

[0051] While the two extrusion blocks 17 are used to squeeze the bearing body 7 in a stationary state and a moving state, the two sets of rectangular plates 18 located on the outer walls of the two extrusion blocks 17 can be synchronously controlled to move in a direction close to each other, so as to seal the bearing body 7 between the two extrusion blocks 17, thereby preventing a small amount of unqualified bearing bodies 7 from breaking during the extrusion process of the bearing body 7 by the two extrusion blocks 17, causing fragments to splash outward and cause harm to surrounding staff, thereby further improving the protection effect on surrounding staff.

[0052] After the pressure test of the bearing body 7, the shell 3 can be controlled to rotate upward 90 degrees, and the two electric sliders 14 can be controlled to move upward inside the corresponding arc groove 8, thereby driving the rectangular frame 6 and other components to rotate upward to a horizontal state. At this time, the two double-headed screws 32 can be controlled to rotate together, driving the two corresponding rectangular plates 18 to move in the direction away from the extrusion block 17, and a circular counterweight block with a diameter smaller than the diameter of the bearing body 7 is placed on the top of the bearing body 7, and then two of the rectangular plates 18 are controlled to move in a direction close to each other and docked. With the help of the reversal of the double-headed screw 32, the two rectangular plates 18 are driven to move together in the direction close to the extrusion block 17, and the circular counterweight block is pressed so that the circular counterweight block is tightly abutted against the bearing body 7. At this time, the drive motor 9 is continued to be controlled to drive the bearing body 7 to rotate, so that the torque of the bearing body 7 itself can be detected.

[0053] After the torque detection of the bearing body 7, the circular counterweight block is removed, and the two double-headed screws 32 are controlled to reverse, driving the two groups of rectangular plates 18 to move in the direction close to the extrusion block 17, and then the two groups of rectangular plates 18 are controlled to move in the direction close to each other and abut, and the bearing body 7 is sealed in the position between the two extrusion blocks 17 again. The output end of the external preset oil delivery mechanism is connected to the connecting end 23 through a hose, so that the lubricating oil delivered by the external oil delivery mechanism can enter the cavity through the connecting end 23 and be discharged to the surface of the bearing body 7 through the oil outlet 37. At this time, the rubber pads 30 arranged on the outer wall of the side where two rectangular plates 18 are close to each other are tightly abutted, which can prevent the lubricating oil from leaking outward, and the multiple rectangular plates 18 are tightly abutted against the rubber sealing strips 21 arranged on the side where the two extrusion blocks 17 are close to each other, further preventing the lubricating oil from leaking outward.

[0054] As the bearing body 7 continues to rotate, the lubricating oil can enter the interior of the bearing body 7, and after the bearing body 7 continues to rotate for a period of time, the housing 3 is controlled to rotate downward and reset, and the two electric sliders 14 are controlled to move downward and reset inside the corresponding arc grooves 8, driving the rectangular frame 6 to rotate and reset to a vertical state, and controlling the two rectangular plates 18 to move away from each other and open. The staff can determine whether there are metal particles, wear powder, moisture or other contaminants in the bearing body 7 by sampling and analyzing the lubricating oil around the bearing body 7. Normal lubricating oil should be clean and transparent, while abnormal oil may be a fault in the bearing body 7. Oil detection can detect early signs of failure of the bearing body 7 and ensure the normal operation of the subsequent bearing body 7 during actual use.

[0055] After all the inspection work on the bearing body 7 is completed, the telescopic ends of the multiple groups of second electric telescopic rods 13 can be controlled to retract, driving the multiple clamping plates 12 to move in the direction close to the round block 11, so that the inner wall of the bearing body 7 loses the clamping and fixing of the multiple clamping plates 12, and then the telescopic end of the first electric telescopic rod 10 is controlled to retract, driving the round block 11 to move in the direction away from the rectangular frame 6, and the shell 3 is controlled to drive the drive motor 9 and other components to rotate upward to a vertical state. At this time, the rectangular frame 6 can be rotated downward 90 degrees to a horizontal state with the help of the rotating shafts set at both ends, and the two extrusion blocks 17 are controlled to release the clamping effect on the outer ring of the bearing body 7, so that the bearing body 7 falls downward accordingly. It falls on the inclined surface on the left side of the top of the monitoring station body 1, and is automatically discharged downward with the guidance of two of the guide plates 5, so as to achieve the effect of automatic unloading and discharge of the bearing body 7 after detection; and in the process of the above-mentioned multiple tests on the bearing body 7, if the bearing body 7 fails in one of the tests, it can be moved inside the corresponding arc groove 8 with the help of two electric sliders 14, driving the rectangular frame 6 to move to the upper side of the inclined surface on the right side of the monitoring station body 1, and repeating the above-mentioned steps of automatic unloading and discharge of the bearing body 7, so that the unqualified bearing body 7 can be discharged downward through the inclined surface on the right side of the top of the monitoring station body 1, so as to achieve the effect of automatically classifying and unqualified bearing bodies 7.
