[0036] In this embodiment, the pressure sensor 3 is installed at the bottom of the base 2, and the pressure sensor 3 is connected to an external display device. When under pressure, the pressure value will be displayed on the display device; the first mounting seat 4 is pressed on the pressure sensor 3, and two first sliding blocks 5 are slidably arranged in the first mounting seat 4. The first driving mechanism 6 can be used to drive the two first sliding blocks 5 to slide in opposite directions, thereby driving the two clamping blocks 7 to slide in opposite directions. The two clamping blocks 7 are closed to vertically clamp and install the bearing. Due to the setting of the V-groove 71, it is possible to adapt to clamp bearings of different outer diameters. The size of the installation shaft 10 is fixed, so the present application can detect bearings with the same inner diameter and different outer diameters; the two telescopic rods 8 can be freely extended and retracted. When not in use, the telescopic rods 8 are the shortest under the action of gravity. The two installation frames 9 are used to place the installation shafts 10. The lifting mechanism 11 is used to drive the second installation seat 12 to rise and fall, and finally drive the two pressing blocks 15 to rise and fall. Two second sliding blocks 13 are slidably arranged in the second installation seat 12. The second driving mechanism 14 can be used to drive the two second sliding blocks 13 to slide in opposite directions, thereby driving the two pressing blocks 15 to slide in opposite directions. Therefore, different bearings can be detected. The difference in width makes the two pressing blocks 15 as close to the two sides of the bearing as possible when applying radial load to the installation shaft 10; when in use, the installation shaft 10 is slid out of the two installation frames 9, and then the bearing is vertically placed between the two clamping blocks 7, and the first driving mechanism 6 is used to drive the two clamping blocks 7 to move closer to each other to clamp the bearing vertically, and then the installation shaft 10 is passed through the inner ring of the bearing, and the two ends are passed through the two installation frames 9. At this time, the pressure sensor 3 is pressurized, and the pressure value on the display device at this time is recorded as the initial pressure value, and then the lifting mechanism 11 drives the two pressing blocks 15 to press down and slightly press on the On the mounting shaft 10, the second driving mechanism 14 is used to adjust the two pressing blocks 15 so that the two pressing blocks 15 are as close to the two sides of the bearing as possible, and then the lifting mechanism 11 drives the two pressing blocks 15 to continuously press down until the bearing is deformed, and the pressure value on the display device at this time is recorded as the final pressure value. The difference between the final pressure value and the initial pressure value is the ultimate radial bearing capacity of the bearing; using the above method, when the ultimate radial load of the bearing is tested, the bearing is installed on the mounting shaft 10, and a radial load is applied to the mounting shaft 10 and transmitted to the bearing, so as to be more in line with the actual working condition of the bearing, and the test result is more accurate.

[0037] Furthermore, the two fastening screws 16 are respectively threadedly connected to the two installation frames 9 and pass through the two installation frames 9 respectively.

[0038] In this embodiment, when the installation shaft 10 needs to be slid, the two tightening screws 16 are loosened, and when the installation shaft 10 needs to be fixed, the two tightening screws 16 are tightened to tighten the installation shaft 10.

[0039] Furthermore, the first double-threaded screw 61 is rotatably connected to the first mounting seat 4 , and is threadedly connected to the two first sliders 5 respectively, and passes through the two first sliders 5 respectively; the first knob 62 is fixedly arranged on one side of the first double-threaded screw 61 .

[0040] In this embodiment, the thread of the first double-threaded screw 61 is divided into two left and right sections, and the thread directions of the two sections are opposite. Rotating the first double-threaded screw 61 can drive the two first sliders 5 to slide in opposite directions, and the first knob 62 is used to facilitate the rotation of the first double-threaded screw 61.

[0041] Furthermore, the sleeve 81 is fixedly disposed on the top of the first mounting seat 4 ; the sliding rod 82 is slidably connected to the sleeve 81 , and is fixedly connected to the mounting frame 9 , and is located inside the sleeve 81 .

[0042] In this embodiment, the telescopic rod 8 is composed of the sleeve 81 and the sliding rod 82. When the sliding rod 82 slides, the length of the telescopic rod 8 can be changed, so it can adapt to bearings with different outer diameters. After the mounting shaft 10 passes through the bearing, the sliding rod 82 will not provide support force to the mounting frame 9.

[0043] Furthermore, the bracket 111 is fixedly arranged on the top of the support platform 1 ; the hydraulic cylinder 112 is fixedly arranged on the bracket 111 , and the output end of the hydraulic cylinder 112 is fixedly connected to the second mounting seat 12 .

[0044] In this embodiment, the bracket 111 is used to install the hydraulic cylinder 112 at a high place, and the hydraulic cylinder 112 is used to drive the second mounting seat 12 to rise and fall, and finally drive the two pressing blocks 15 to rise and fall.

[0045] Furthermore, the two guide rods 113 are respectively fixedly connected to the second mounting seat 12 , and are respectively slidably connected to the bracket 111 , and respectively pass through the bracket 111 .

[0046] In this embodiment, the two guide rods 113 are used to constrain and guide the second mounting seat 12 so that the second mounting seat 12 can only be lifted up and down vertically.

[0047] Furthermore, the second double-threaded screw 141 is rotatably connected to the second mounting seat 12 , and is threadedly connected to the two second sliders 13 respectively, and passes through the two second sliders 13 respectively; the second knob 142 is fixedly arranged on one side of the second double-threaded screw 141 .

[0048] In this embodiment, the thread of the second double-threaded screw 141 is divided into two left and right sections, and the thread directions of the two sections are opposite. Rotating the second double-threaded screw 141 can drive the two second sliders 13 to slide in opposite directions, and the second knob 142 is used to facilitate the rotation of the second double-threaded screw 141.

[0049] Furthermore, the two top rods 17 are respectively slidably connected to the support platform 1 and respectively pass through the support platform 1; the two top blocks 18 are respectively fixedly set on the top of the two top rods 17 and respectively pass through the two rectangular openings 201; the mounting plate 19 is fixedly set at the bottom of the two top rods 17; the screw rod 20 is rotatably connected to the support platform 1, and is threadedly connected to the mounting plate 19 and passes through the mounting plate 19; the third knob 21 is fixedly set at the bottom of the screw rod 20.

[0050] In this embodiment, the rectangular opening 201 is used to install the top block 18. When not in use, if the first mounting seat 4 continues to press on the pressure sensor 3, it is easy to affect the service life of the pressure sensor 3. Therefore, when not in use, the third knob 21 is turned to rotate the screw 20. The screw 20 drives the mounting plate 19 to move upward. The mounting plate 19 drives the two top blocks 18 to move upward through the two top rods 17. The upward movement of the two top blocks 18 lifts the first mounting seat 4 upward, so that the first mounting seat 4 moves up and away from the pressure sensor 3, and the pressure sensor 3 does not bear any load.

[0051] In the present embodiment, a detection device for bearing production is described, wherein the pressure sensor 3 is installed at the bottom of the base 2, and the pressure sensor 3 is connected to an external display device. When under pressure, the pressure value will be displayed on the display device; the first mounting seat 4 is pressed on the pressure sensor 3, and two first sliding blocks 5 are slidably arranged in the first mounting seat 4. The first driving mechanism 6 can be used to drive the two first sliding blocks 5 to slide in opposite directions, thereby driving the two clamping blocks 7 to slide in opposite directions. The two clamping blocks 7 are closed to vertically clamp and install the bearing. Due to the setting of the V-shaped groove 71, it can be adapted to clamp different external The two telescopic rods 8 can be freely extended and retracted. When not in use, the telescopic rods 8 are at their shortest under the action of gravity. The two mounting frames 9 are used to place the mounting shafts 10. The lifting mechanism 11 is used to drive the second mounting seat 12 to rise and fall, and finally drive the two pressing blocks 15 to rise and fall. Two second sliding blocks 13 are slidably arranged in the second mounting seat 12. The second driving mechanism 14 can be used to drive the two second sliding blocks 13 to slide in opposite directions, thereby driving the two pressing blocks 15 to slide in opposite directions. Therefore, the two second sliding blocks 13 can be driven to slide in opposite directions. According to the different widths of different bearings, the two pressing blocks 15 are as close to the two sides of the bearing as possible when applying radial load to the installation shaft 10; when in use, the installation shaft 10 is slid out of the two installation frames 9, and then the bearing is vertically placed between the two clamping blocks 7, and the first driving mechanism 6 is used to drive the two clamping blocks 7 to move closer to each other to clamp the bearing vertically, and then the installation shaft 10 is passed through the inner ring of the bearing, and the two ends are passed through the two installation frames 9. At this time, the pressure sensor 3 is pressurized, and the pressure value on the display device at this time is recorded as the initial pressure value, and then the lifting mechanism 11 drives the two pressing blocks 15 to press down slightly. The two pressing blocks 15 are pressed onto the installation shaft 10, and the second driving mechanism 14 is used to adjust the two pressing blocks 15 so that the two pressing blocks 15 are as close to the two sides of the bearing as possible. Then the lifting mechanism 11 drives the two pressing blocks 15 to continuously press down until the bearing is deformed. The pressure value on the display device at this time is recorded as the final pressure value. The difference between the final pressure value and the initial pressure value is the ultimate radial bearing capacity of the bearing. By adopting the above method, when the ultimate radial load of the bearing is tested, the bearing is installed on the installation shaft 10, and a radial load is applied to the installation shaft 10 and transmitted to the bearing, so as to be more in line with the actual working condition of the bearing and make the test result more accurate.
