[0032] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0033] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0034] As described in the background technology, traditional bearing flexibility testing is usually done manually, that is, the quality is judged based on the inspector's experience of hand feeling. This involves a large subjective factor and cannot guarantee the accuracy of bearing flexibility testing. In addition, manual testing is inefficient, and for bearing manufacturers, a large amount of human resources are required, resulting in increased production costs. For this reason, this embodiment provides a bearing flexibility testing device, which first fixes the outer ring of the bearing through a limit assembly, and then controls the rotation of the inner ring of the bearing and stops outputting power, allowing the inner ring to continue rotating under the action of inertia, and calculates the number of rotations of the inner ring of the bearing, thereby obtaining the bearing flexibility test result and ensuring the accuracy of the bearing test, thereby avoiding the differences in manual testing and ensuring the uniformity of the testing standards. It also has high work efficiency, reduces production costs, and can meet the needs of modern automated production.

[0035] See also Figure 1 - Figure 5 This embodiment proposes a flexibility detection device for bearings, including a workbench 1, the inner wall of the workbench 1 is hinged with a protective door 10 for protecting the internal equipment of the workbench 1 through a pin shaft, and handles 11 are installed on the front of the two protective doors 10.

[0036] By providing the protective door 10 and the handle 11, the bearing flexibility detection equipment placed inside the workbench 1 can be protected, and the handle 11 can be conveniently pulled to rotate, so that the equipment inside the workbench 1 can be taken out and stored.

[0037] The bottom surface of the workbench 1 is threadedly connected with a leveling screw 12. By setting the leveling screw 12, the flexibility detection device for the bearing can be leveled to ensure the accuracy of the detection. One side and the other side of the workbench 1 are fixedly connected with a placement frame 13. By setting the placement frame 13, the bearings to be detected and the bearings after detection can be conveniently classified and stored, thereby improving convenience during use.

[0038] The inner wall of the workbench 1 is fixedly connected with a bearing locating seat 9 by bolts, and the upper surface of the bearing locating seat 9 is provided with a countersunk hole to ensure that the inner ring of the bearing to be tested can rotate freely.

[0039] A support block 2 is fixedly connected to the upper surface of the workbench 1, a first cylinder 3 is installed on the inner wall of the support block 2, a slide plate 4 slidably connected to the support block 2 is fixedly connected to the telescopic end of the first cylinder 3, a drive motor 5 is installed on the upper surface of the slide plate 4, a pneumatic clutch 6 is fixedly connected to the output shaft end of the drive motor 5, and a gear plate 7 is connected to the bottom of the pneumatic clutch 6.

[0040] Connecting the first cylinder 3 to power and starting it can drive the slide plate 4 to slide up and down along the inner wall of the support block 2. Then connecting the drive motor 5 to power and starting it can drive the gear plate 7 to rotate through the pneumatic clutch 6, thereby performing a flexibility test on the bearing placed on the workbench 1.

[0041] The pneumatic clutch 6 is composed of a group of toothed friction plates, springs and end covers. When the air pressure acts on the piston, the piston is pushed to loosen the friction plates, thereby achieving the separation of the clutch. When the air pressure decreases, the spring will pull the piston back and the friction plates will re-engage to achieve the engagement of the clutch. The pneumatic clutch 6 is provided with a connecting pipe for connecting and controlling the air pressure.

[0042] The bottom surface of the slide plate 4 is fixedly connected with a connecting plate 16 , the inner wall of the connecting plate 16 is installed with an infrared emitter 17 , the inner wall of the gear plate 7 is inlaid with a plurality of circumferentially arranged reflective blocks 18 , and the infrared emitter 17 is adapted to the reflective blocks 18 .

[0043] The bottom of the gear plate 7 is chamfered, which makes it easy for the gear plate 7 to be inserted into the inner hole of the bearing to limit and fix the inner ring of the bearing, thereby facilitating the rotation of the inner ring of the bearing. After that, the number of rotations of the inner ring of the bearing can be calculated by using the corresponding infrared transmitter 17 and the reflective block 18, thereby obtaining the bearing flexibility test result.

[0044] A limit assembly for improving the bearing flexibility detection accuracy is arranged above the workbench 1. The limit assembly includes support plates 801 fixed to one side and the other side of the slide plate 4. The inner walls of the two support plates 801 are installed with second cylinders 802. The telescopic ends of the two second cylinders 802 are fixedly connected with sleeves 803.

[0045] The support plate 801 can be driven to move up and down by the slide plate 4, and the second cylinder 802 is powered on and started, and its telescopic end is extended and retracted, which can drive the sleeve 803 to move, thereby fixing bearings of different sizes.

[0046] The inner walls of the two sleeves 803 are slidably connected with sliding rods 804, and the interiors of the two sleeves 803 are provided with reset springs 805 respectively fixed to the sleeves 803 and the sleeves 803. The two sliding rods 804 are fixedly connected with arc blocks 806 at one end away from the sleeves 803. The sleeves 803 can drive the sliding rods 804 to move through the reset springs 805, and then drive the arc blocks 806 to fit with the outer ring of the bearing, so as to achieve the limit fixation of the outer ring of the bearing, thereby ensuring the accuracy of the bearing detection.

[0047] The inner walls of the two arc blocks 806 are fixedly connected with friction pads 15 for improving the contact stability with the outer ring of the bearing. By providing the friction pads 15, the friction force when the arc blocks 806 contact the outer ring of the bearing can be increased, thereby improving the stability when fixing the outer ring of the bearing.

[0048] A display screen 14 is fixedly connected to the upper surface of the workbench 1, and the first cylinder 3, the drive motor 5, the second cylinder 802, the sleeve 803 and the return spring 805 are all electrically connected to the display screen 14. By setting up the display screen 14, the test results of the flexibility detection device for the bearing can be conveniently displayed and broadcast, thereby improving the convenience of using the equipment.

[0049] Each electrical component in the present invention is a conventional device purchased on the market and known to those skilled in the art. The model can be selected or customized according to actual needs. The setting method, installation method and electrical connection method thereof can be debugged and operated according to the requirements of the instruction manual for those skilled in the art, and will not be described in detail here.

[0050] The components in the drawings of the present invention are only for style reference and are not for specific size standards. The specific sizes are determined according to actual production requirements. At the same time, the materials of the components can be replaced accordingly according to actual needs.

[0051] The working principle of the bearing flexibility detection device proposed by the present invention is as follows:

[0052] Preparation stage:

[0053] Place the bearing to be tested in the bearing positioning seat 9 on the workbench 1 to ensure that the inner ring of the bearing can rotate freely.

[0054] Close the protective door 10 to ensure the safety and protection of the equipment inside the workbench 1.

[0055] By adjusting the leveling screw block 12, the entire detection device is ensured to be in a horizontal state to ensure the accuracy of the detection.

[0056] Limit fixation stage:

[0057] The first cylinder 3 is started, and its telescopic end drives the slide plate 4 to slide downward along the inner wall of the support block 2, thereby driving the support plate 801 and the second cylinder 802 to move downward to above the bearing.

[0058] The second cylinder 802 is started, and its telescopic end drives the sleeve 803 to move. The sleeve 803, through the action of the return spring 805, pushes the slide bar 804 and the arc block 806 to fit the outer ring of the bearing, thereby achieving preliminary limit fixation of the outer ring of the bearing.

[0059] Continue to move the gear plate 7 so that its bottom is stuck into the inner hole of the bearing, and ensure that the rotation center of the gear plate 7 and the center of the bearing are on the same horizontal line.

[0060] Under the reset action of the reset spring 805, the arc block 806 further tends to fit the outer ring of the bearing, thereby achieving stable positioning of the outer ring of the bearing.

[0061] Detection phase:

[0062] The driving motor 5 is started to drive the gear plate 7 to rotate through the pneumatic clutch 6, thereby driving the inner ring of the bearing to rotate.

[0063] When the inner ring of the bearing reaches a specified speed, pressurized gas is injected into the pneumatic clutch 6 to separate it. At this time, the inner ring of the bearing and the gear plate 7 continue to rotate synchronously under the action of inertia.

[0064] The infrared emitter 17 emits infrared rays, and the infrared rays are reflected by the reflective block 18. The infrared emitter 17 records the number of reflections, and calculates the number of revolutions of the gear plate 7 (ie, the inner ring of the bearing) according to the known number of the reflective blocks 18.

[0065] Results presentation stage:

[0066] The detected number of rotations of the inner ring of the bearing is displayed and reported through the display screen 14 to obtain the bearing flexibility detection result.

[0067] According to the detection results, the bearings are classified and stored in corresponding placement boxes 13.

[0068] Reset phase:

[0069] The drive motor 5 and the pneumatic clutch 6 are turned off.

[0070] The second cylinder 802 is started, so that its telescopic end drives the sleeve 803 and the arc block 806 to retract, thereby releasing the limit fixation on the outer ring of the bearing.

[0071] The first cylinder 3 is started, so that its telescopic end drives the slide plate 4 and the support plate 801 to rise and return to the initial position.

[0072] Subsequent operations:

[0073] Open the protective door 10, take out the tested bearing, and prepare to test the next bearing.
