Description

Technical Field

[0001] This application relates to the field of bearing testing, and in particular to a bearing testing device. Background Technology

[0002] In the field of machinery manufacturing and testing, bearings, as key components in numerous mechanical equipment, directly affect the operational stability, reliability, and service life of the equipment. With the continuous development of industry, the quality requirements for bearings are becoming increasingly stringent, and bearing testing technology is constantly advancing accordingly. Accurate and efficient bearing testing can promptly detect defects and problems in bearings, preventing equipment damage and production accidents caused by bearing failures, which is of great significance for improving production efficiency and reducing costs. Advanced bearing testing technology can also drive the improvement and upgrading of bearing manufacturing processes, promoting the development of the entire machinery industry.

[0003] In traditional bearing testing, multiple methods are typically employed to perform various performance tests on the bearing. First, specific fixtures are used to fix the bearing on the testing platform, ensuring its stability during testing for accurate measurements. Bearing placement and positioning often rely on manual operation; operators use experience to position the bearing appropriately and then fine-tune it using auxiliary tools. After testing, the tested bearing is usually removed manually from its testing location to proceed to the next bearing. Furthermore, testing different bearing models often requires changing the testing fixtures and equipment based on the bearing's specific dimensions and specifications to meet varying testing requirements.

[0004] However, existing bearing inspection methods have significant drawbacks. Manually placing and positioning bearings is not only inefficient but also makes it difficult to guarantee placement accuracy each time, easily leading to errors in the inspection results. Manually handling inspected bearings increases labor intensity and increases the risk of damage due to human error. Frequent changes to different inspection fixtures and equipment increase inspection costs, waste significant time, and reduce efficiency. Furthermore, existing inspection methods are difficult to automate and cannot meet the needs of large-scale production. Utility Model Content

[0005] To improve bearing testing efficiency, this application provides a bearing testing device.

[0006] This application provides a bearing testing device, which adopts the following technical solution: A bearing testing device includes a base. The base is used to support the bearing. The base has a preset detection point corresponding to the bearing. The base is provided with a discharge port. The distance from the discharge port to the preset detection point is not greater than the outer diameter of the bearing.

[0007] By adopting the above technical solution, the bearing to be tested is placed on the base, and the bearing is moved so that its axis coincides with the preset test point to complete the test. After the test is completed, the next bearing to be tested is moved to the preset test point. The next bearing pushes the current bearing to move to the feed port and causes the center of the current bearing to detach from the base. Gravity causes the bearing to detach from the base at the feed port.

[0008] Preferably, it also includes a base. The base is detachably connected to the machine base.

[0009] By adopting the above technical solution, the base can be replaced according to the bearing model (diameter) to adapt to different bearing models.

[0010] Preferably, the bolt passes through the base and is threaded to the machine base.

[0011] By adopting the above technical solution, the base and the base can be detached; at the same time, when the base is connected to the base, the connection is ensured to be reliable and stable.

[0012] Preferably, it also includes a feeding chute and a sorting plate. The feeding chute is used to connect to the feeding port, and the feeding chute is provided with a notch. The sorting plate is slidably / rotatably connected to the unloading chute; When the sorting plate blocks the notch, the sorting plate serves to prevent the bearing from detaching from the notch. When the sorting plate is disengaged from the notch, the sorting plate is used to disengage the bearing from the notch.

[0013] By adopting the above technical solution, after the bearing inspection is completed, the bearing detaches from the base from the discharge port and falls into the discharge chute. Based on the bearing inspection results, the sorting plate is controlled to block or detach from the notch, thereby separating qualified and unqualified bearings.

[0014] Preferably, the notch is located at the bottom surface of the feeding chute.

[0015] By adopting the above technical solution, when the sorting plate is detached from the notch, gravity causes the bearing to detach from the notch and the feeding slide.

[0016] Preferably, when the sorting plate is slidably connected to the unloading slide, the sliding direction of the sorting plate is perpendicular to the bottom surface of the unloading slide.

[0017] By adopting the above technical solution, the sorting plate can quickly detach from the notch.

[0018] Preferably, when the sorting plate is rotatably connected to the feeding chute, the rotation axis of the sorting plate is located at the end of the notch away from the feeding port.

[0019] By adopting the above technical solution, the end of the sorting plate near the discharge port can quickly detach from the notch. At the same time, even if there is a drop between the end of the sorting plate near the discharge port and the discharge chute, the rotating connection between the sorting plate and the discharge chute remains stable, and the bearing can move along the discharge chute.

[0020] Preferably, it also includes a tray and a pusher block. The support plate is flush with the upper surface of the base and is used to support the bearing. The pusher block is provided with a groove for the bearing to be inserted, and the pusher block is used to push the bearing on the tray closer to the preset detection point.

[0021] By adopting the above technical solution, the pusher pushes a single bearing close to the preset inspection point to realize the transport of the bearing and to push the previous bearing away from the base.

[0022] Preferably, the pusher has two contact surfaces, which form the groove, and the contact surfaces are used to make contact / point contact with the outer periphery of the bearing.

[0023] By adopting the above technical solution, different bearing models result in different bearing diameters. For any type of bearing, two line contacts / point contacts are ensured to stably drive the bearing to move.

[0024] If an arc-shaped groove is used, only the outer circumference of a bearing of a certain diameter can be stably pushed to move by fitting against the groove wall; bearings with smaller diameters may wobble in the groove, resulting in unstable bearing movement.

[0025] Preferably, it also includes a conveyor belt. The conveyor belt is used to transport the bearings to the pallet.

[0026] By adopting the above technical solutions, it is beneficial to achieve automated detection.

[0027] Preferably, it also includes a pressure head. One end of the pressure head has a conical surface on its outer periphery. The axis of the conical surface is collinear with a preset detection point. The conical surface is used to abut against the inner periphery of the bearing.

[0028] By adopting the above technical solution, the inner circumference of the tapered contact bearing is precisely positioned, ensuring that the bearing axis coincides with the preset detection point to complete the detection.

[0029] In summary, this application includes at least one of the following beneficial technical effects: 1. The bearing to be tested is placed on the base. After the test is completed, the current bearing can be pushed off the base from the feeding port by the next bearing, avoiding manual handling and improving the testing efficiency; 2. The base is detachably connected to the machine base, and the base can be replaced according to the bearing model to adapt to different bearing models, reducing the cost and time of changing testing fixtures; 3. Based on the bearing inspection results, the sorting plate can be controlled to block or detach from the notch, thus separating qualified and unqualified bearings; 4. The pusher pushes a single bearing close to the preset detection point, realizing the bearing delivery and pushing the previous bearing away from the base, and the groove formed by the two contact surfaces can stably push different types of bearings to move; 5. The conveyor belt transports the bearing to the pallet, which facilitates automated testing. The conical surface of the pressure head contacts the inner circumference of the bearing for precise positioning, ensuring testing accuracy. Attached Figure Description

Detailed Implementation

[0036] The present application will be further described in detail below with reference to the accompanying drawings.

[0037] Reference Figure 1 and Figure 2 This application discloses a bearing testing device, including a base 11, a base 2, and a pressure head 31.

[0038] The base 2 is detachably connected to the base 11. The base 2 is used to support the bearing. The base 2 has a preset detection point corresponding to the bearing. The base 2 is provided with a discharge port 21. The distance from the discharge port 21 to the preset detection point is not greater than the outer diameter of the bearing.

[0039] The pressure head 31 has a tapered surface 311 on its outer periphery at one end. The axis of the tapered surface 311 is collinear with the preset detection point. The tapered surface 311 is used to abut against the inner circumference of the bearing so that the center of the bearing coincides with the preset detection point. The pressure head 31 is slidably connected to the machine base 11, and the sliding direction of the pressure head 31 is parallel to the axis of the tapered surface 311.

[0040] In the attached diagram: the upper surface of the base 2 is horizontal, the base 2 is disc-shaped, and the preset detection point coincides with the center of the base 2; a through hole 22 is provided at the center of the base 2, and the bolt passes through the through hole 22 and is threaded to the machine base 11; the discharge port 21 makes the base 2 ultimately form an arc shape (with a central angle greater than 180°); The axis of the conical surface 311 is collinear with the axis of the base 2, that is, the axis of the conical surface 311 is vertical; the conical surface 311 is located at the lower end of the pressure head 31.

[0041] More specifically: the base 11 includes a frame 111 and a turntable 112; the turntable 112 is rotatably connected to the frame 111; the base 2 is detachably connected to the turntable 112, such that the center of the base 2 coincides with the rotation axis of the turntable 112; the pressure head 31 is slidably connected to the frame 111. A bearing testing device also includes a clamping cylinder 32, the cylinder body of which is fixedly connected to the frame 111, and the piston rod of the clamping cylinder 32 is used to drive the pressure head 31 to move. The pressure head 31 presses the bearing, and the frictional force keeps the pressure head 31 and the inner ring of the bearing relatively stationary, and the base 2 and the outer ring of the bearing relatively stationary. That is, the drive motor 12 drives the turntable 112 to rotate through the coupling. The turntable 112 and the base 2 drive the outer ring of the bearing to rotate through the frictional force, and the pressure head 31 keeps the inner ring of the bearing stationary through the frictional force, so as to measure the frictional torque of the bearing through the sensor 13.

[0042] Reference Figure 1 and Figure 3 A bearing testing device also includes a conveyor belt 41, a pallet 42, and a pusher block 51.

[0043] The pallet 42 is fixedly connected to the frame 111. The upper surface of the pallet 42 is flush with the upper surface of the base 2, and the pallet 42 is used to support the bearing. The conveyor belt 41 is used to transport the bearing to the pallet 42.

[0044] The pusher block 51 has two contact surfaces 511, which form a groove 512. The groove 512 is used for bearing insertion, and the contact surfaces 511 are used for contacting / point contact with the outer circumference of the bearing. Preferably, the contact surfaces 511 are used for contacting the outer circumference of the bearing. The pusher block 51 is used to push the bearing on the support plate 42 to move onto the base 2 and bring the bearing closer to the preset detection point.

[0045] More specifically: the distance from the bearing center to the preset detection point is D, the radius of the lower end of the pressure head 31 is r (i.e. the minimum radius of the cone surface 311 is r), and the radius of the inner circumference of the bearing is R. The push block 51 is used to make D < Rr so that the lower end of the pressure head 31 can be inserted into the bearing.

The push motor 56 drives the lead screw of the lead screw pair 52 to rotate through the belt transmission mechanism, thereby driving the push block 51 to move and controlling the moving distance of the push block 51.

[0047] In another embodiment: a bearing detection device further includes a push cylinder; the piston rod of the push cylinder is horizontal and perpendicular to the conveying direction of the conveyor belt 41; the cylinder body of the push cylinder is connected to the base 11, and the piston rod of the push cylinder is connected to the push block 51; The contact surface 511 is a plane, and the two contact surfaces 511 form a V shape.

[0049] The discharge chute 61 is connected to the discharge port 21, and the discharge chute 61 is provided with a notch 611. The sorting plate 62 is slidably / rotatably connected to the discharge chute 61. When the sorting plate 62 blocks the notch 611: the sorting plate 62 is used to prevent the bearing from disengaging from the notch 611. When the sorting plate 62 disengages from the notch 611: the sorting plate 62 is used to allow the bearing to disengage from the notch 611.

[0050] In the attached diagram: Notch 611 is located at the bottom surface of the feeding chute 61; The sorting plate 62 is slidably connected to the unloading slide 61, and the sliding direction of the sorting plate 62 is perpendicular to the bottom surface of the unloading slide 61. A bearing testing device also includes a sorting cylinder 63; the cylinder body of the sorting cylinder 63 is fixedly connected to the frame 111, and the piston rod of the sorting cylinder 63 is connected to the sorting plate 62.
