[0044] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, the pressure detection mechanism 2 includes a pressure display 21. The pressure display 21 is fixedly installed on the front of the bearing detection platform 1. A first signal transmission line 22 is fixedly installed on the back of the pressure display 21.

Two pressure sensors 25 are fixedly installed at the top of the second signal transmission line 24.

[0045] During operation, when the bearing being tested is compressed, the pressure sensor 25 detects the pressure data of the bearing being tested, and then transmits the pressure data to the pressure converter 23 for digital conversion via the second signal transmission line 24. The pressure converter 23 then transmits the converted pressure data to the first signal transmission line 22, and then transmits the pressure data to the pressure display 21 for display, thus displaying the pressure data and making it convenient for personnel to observe and record.

[0046] Furthermore, such as Figure 1 , Figure 2 and Figure 4As shown, the position adjustment mechanism 3 includes a first motor 31. The first motor 31 is fixedly installed on one side of the bearing testing platform 1. The output end of the first motor 31 is splinedly connected to a first rotating rod 32. One end of the first rotating rod 32 is fixedly installed with a first threaded conveying rod 33, and the first threaded conveying rod 33 is set in the stroke groove 7. The surface of the first threaded conveying rod 33 is threadedly connected to a first threaded block 35 through a threaded hole 34. A frame 4 is fixedly installed on the front side of the first threaded block 35.

[0047] During operation, the first motor 31 is connected to an external power source to drive the first rotating rod 32 to rotate, which in turn drives the first threaded conveying rod 33 to rotate, which in turn drives the first threaded block 35 to move, thereby adjusting the position of the cleaning mechanism 5.

[0048] Furthermore, such as Figure 1 , Figure 2 and Figure 5 As shown, the cleaning mechanism 5 includes a second motor 51. The second motor 51 is fixedly installed on the front of the frame 4.

[0050] like Figure 1 and Figure 6 As shown, a feeding assembly 9 is provided in the middle of the interior of the bearing testing bench 1. The feeding assembly 9 includes:

[0051] A loading port 91 is provided on one side of the inner wall of the bearing testing platform 1. A movable groove is provided in the middle of the interior of the bearing testing platform 1. The bearing testing platform 1 is installed inside the movable groove. A second threaded block 96 and a slider are fixed on both sides of the bearing testing platform 1 respectively. A second threaded conveying rod 97 is inserted inside the second threaded block 96. A third motor 98 is connected to one end of the second threaded conveying rod 97. A support slide rod 99 is inserted inside the slider. Clamping plates 92 are installed on both sides above the movable base plate 95. Two second hydraulic cylinders 93 are connected to one side of the clamping plate 92, and two grooves 94 are opened on the other side.

[0052] During operation, the bearing to be tested is placed between the grooves 94 of the two clamping plates 92. Then, the clamping plates 92 are moved by the second hydraulic cylinder 93, so that the two clamping plates 92 clamp the bearing to be tested and fix it. Then, the third motor 98 drives the second threaded conveying rod 97 to rotate, so that the second threaded conveying rod 97 pushes the second threaded block 96 and the movable base plate 95 to move. The slider and support slide rod 99 on one side of the movable base plate 95 are used to provide sliding support for the movable base plate 95 and limit the movement trajectory of the movable base plate 95. When the movable base plate 95 moves, it is pulled into the interior of the movable groove. At this time, the bearing to be tested is moved to a suitable position so that the bearing to be tested corresponds to the pressure plate 123.

[0053] Furthermore, such as Figure 1 , Figure 2 and Figure 7 As shown, the pressing mechanism 12 includes a first hydraulic cylinder 121. The first hydraulic cylinder 121 is fixedly installed on the top of the top plate 11, and a pressing disc 122 is fixedly installed on the bottom of the first hydraulic cylinder 121. A pressure plate 123 is fixedly installed on the bottom of the pressing disc 122.

[0054] During operation, the bearing to be tested is placed in the pressure testing groove 6, and then the first hydraulic cylinder 121 extends and retracts to drive the pressure disc 122 to move. The pressure disc 122 drives the pressure plate 123 to move, and then the pressure plate 123 presses down to test the bearing inside, thus performing a pressure test on the bearing.

[0055] Working principle:

[0056] First, the bearing to be tested is placed between the grooves 94 of the two clamping plates 92. Then, the clamping plates 92 are moved by the second hydraulic cylinder 93, so that the two clamping plates 92 clamp the bearing to be tested and fix it. Next, the third motor 98 drives the second threaded conveying rod 97 to rotate, so that the second threaded conveying rod 97 pushes the second threaded block 96 and the movable base plate 95 to move. The slider and support slide rod 99 on one side of the movable base plate 95 are used to provide sliding support for the movable base plate 95 and limit the movement trajectory of the movable base plate 95. When the movable base plate 95 moves, it is pulled into the interior of the movable groove. At this time, the bearing to be tested is moved to a suitable position so that the bearing to be tested corresponds to the pressure plate 123.

[0057] Secondly, the first hydraulic cylinder 121 extends and retracts, driving the lowering disc 122 to move. The lowering disc 122 drives the pressure plate 123 to move. The pressure plate 123 presses down and moves to perform pressure testing on the internal bearing under test. When the bearing under test is squeezed, the pressure sensor 25 detects the pressure data of the bearing under test. The second signal transmission line 24 transmits the pressure data to the pressure converter 23 for digital conversion. The pressure converter 23 transmits the converted pressure data to the first signal transmission line 22. The first signal transmission line 22 transmits the pressure data to the pressure display 21 for display. The pressure data is displayed.

[0058] Then, the first motor 31, powered by an external power source, drives the first rotating rod 32 to rotate. The first rotating rod 32 drives the first threaded conveying rod 33 to rotate. The first threaded conveying rod 33 drives the first threaded block 35 to move, adjusting the position of the cleaning mechanism 5. The second motor 51, powered by an external power source, drives the second rotating rod 52 to rotate. The second rotating rod 52 drives the transmission rod 53 to rotate. The transmission rod 53 drives the cleaning brush ring 54 to rotate, cleaning the residue to the debris drop outlet for collection.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
