Description

Technical Field

[0001] This utility model belongs to the field of bearing testing technology, and in particular relates to a deviation detection device for the machining of inner and outer rings of bearings. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. During the bearing manufacturing process, it is necessary to measure them using testing devices.

[0003] In the prior art, Chinese utility model patent CN220818923U discloses a deviation detection device for the machining of bearing inner and outer rings, belonging to the field of bearing machining and inspection technology. The support base is L-shaped, and a support plate is fixedly connected to one end of the support base. The surface of the support plate is provided with a sliding groove, and a slide block is slidably connected to the inner wall of the sliding groove. An adjusting rod is rotatably connected to one side of the slide block through a bearing seat. A turntable is fixedly connected to one end of the adjusting rod, and a lifting column is slidably sleeved on one end of the slide block. This deviation detection device for the machining of bearing inner and outer rings can quickly position bearing inner and outer rings of different sizes by setting a stepped positioning block and an adsorption block. It is easy to install and disassemble, which greatly improves the inspection efficiency of bearing inner and outer rings. Furthermore, the slide block and lifting column can drive the detector body to move precisely horizontally, and at the same time, it is convenient for the detection head to move downwards towards the workpiece to be tested. Moreover, it can automatically reset after the test, which greatly improves the ease of use of the detection device.

[0004] In existing technologies, stepped positioning blocks and adsorption blocks can be used to quickly position the inner and outer rings of bearings of different sizes, making assembly and disassembly convenient and greatly improving the inspection efficiency of bearing inner and outer rings. However, there are still some shortcomings in overall use:

[0005] First, the existing technology described above involves fixing both the bearing and the detector body during bearing inspection, making it impossible to inspect the entire bearing. When the bearing is stationary, only one side of the bearing can be inspected, which is limiting and makes it impossible to effectively assess the quality of the bearing, leading to inaccurate test results.

[0006] Secondly, when performing isometric testing of the inner and outer rings, pressing down on the testing instrument causes it to vibrate. This changes the relative position between the sensor and the bearing's inner and outer rings, resulting in measurement errors and inaccurate detected deviations, thus affecting the assessment of bearing quality. Utility Model Content

[0007] This invention addresses the limitations of testing only one side of a bearing when it is stationary, which prevents effective quality assessment and leads to inaccurate test results and measurement errors due to instrument vibration. It provides a bearing inner and outer ring machining deviation detection device.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a deviation detection device for machining inner and outer rings of a bearing, comprising a base, wherein a fixing mechanism is provided on the upper surface of the base for fixing bearings of different sizes, and a movable plate is slidably mounted on one side of the fixing mechanism on the upper surface of the base.

[0009] A drive gear is rotatably mounted on the surface of the movable plate. A driven gear, rotatably mounted on the surface of the movable plate, meshes with the upper surface of the drive gear. A rotating shaft driven by the driven gear is rotatably mounted inside the movable plate. A mounting box is fixedly mounted at one end of the rotating shaft. Two detection plates are slidably mounted inside the mounting box. Photoelectric sensors are provided on the opposite surfaces of the two detection plates and the bearing. A shock-absorbing component is sleeved on the surface of the photoelectric sensor to reduce vibration when the photoelectric sensor detects the bearing.

[0010] By using a driving gear to rotate the driven gear, an electrical sensor can be activated to detect the bearing. This avoids the vibration caused by using a motor, which could lead to errors in the detection results. At the same time, the two gears experience more balanced forces during transmission. This balanced force helps reduce vibration and impact during transmission, thereby improving detection accuracy.

[0011] In the aforementioned bearing inner and outer ring machining deviation detection device, the damping component includes a damping ring sleeved on the surface of a photoelectric sensor and a mounting groove opened inside the detection plate. The photoelectric sensor is fixedly installed inside the mounting groove, and a spring is fixedly installed between the inner wall of the mounting groove and the damping ring.

[0012] By using springs and shock-absorbing rings to dampen the photoelectric sensor, the sensor can remain stable during rotational detection, thus improving the detection effect.

[0013] In the aforementioned bearing inner and outer ring machining deviation detection device, a vibration isolation pad is provided between the photoelectric sensor and the mounting groove.

[0014] Vibration damping pads are used to reduce vibration in photoelectric sensors, thereby improving detection accuracy.

[0015] In the aforementioned bearing inner and outer ring machining deviation detection device, two second lead screws are threaded on the internal threads of the mounting box, and the detection plate is threaded on the surface of the second lead screws.

[0016] By adjusting the second lead screw at the top, the detection plate moves up and down, aligning the photoelectric sensor with the outer ring of the bearing to maintain a suitable detection height. Similarly, adjusting the second lead screw at the bottom aligns the photoelectric sensor with the inner ring of the bearing. After adjustment, the mounting box rotates, causing the two photoelectric sensors to rotate around the inner and outer rings of the bearing respectively, thus enabling the entire bearing to be detected. The inner and outer rings can be detected simultaneously, greatly improving work efficiency and detection accuracy.

[0017] In the aforementioned bearing inner and outer ring machining deviation detection device, the fixing mechanism includes a mounting plate fixedly mounted on the upper surface of the base, a fixing block fixedly mounted on one side of the mounting plate, a limiting plate of increasing size fixedly mounted on the surface of the fixing block, and an electromagnet fixedly mounted inside the limiting plate.

[0018] The bearings are placed on the surface of the limiting plate and then magnetically fixed by an electromagnet. The limiting plates are set from small to large to facilitate the installation of bearings of different sizes, which is practical.

[0019] In the aforementioned bearing inner and outer ring machining deviation detection device, a sliding plate is slidably installed inside the mounting plate, and an arc-shaped support plate is fixedly installed on the upper surface of the sliding plate near the fixed block to support the bearing.

[0020] In the aforementioned bearing inner and outer ring machining deviation detection device, a fixing plate is fixedly installed on the side of the mounting plate away from the support plate, and a threaded rod is installed on the internal thread of the fixing plate. The bottom end of the threaded rod is fixed to the upper surface of the sliding plate and rotates in fit.

[0021] By rotating the threaded rod, the threaded rod pulls the slide plate to move, and the bearing is lifted by the support plate. This is used to support larger bearings, making it easier to fix the bearings and reducing labor intensity.

[0022] In the aforementioned bearing inner and outer ring machining deviation detection device, a first lead screw is rotatably mounted in the inner cavity of the base, and a movable plate is threaded onto the surface of the first lead screw.

[0023] The rotation of the first lead screw causes the moving plate to slide in the second slide groove, bringing the detection device on the moving plate closer to the bearing for detection. The moving plate is a certain distance away from the bearing to facilitate the fixing of the bearing.

[0024] In the aforementioned bearing inner and outer ring machining deviation detection device, a shock-absorbing pad is fixedly installed on the lower surface of the base.

[0025] Vibration damping pads are used to reduce overall vibration in the equipment, further improving detection accuracy.

[0026] In summary, compared with the prior art, the bearing inner and outer ring machining deviation detection device provided by this utility model has the following beneficial effects:

[0027] 1. This utility model, through the setting of a driving gear, driven gear, rotating shaft, mounting box, second lead screw, detection plate and photoelectric sensor, can detect the entire bearing, and at the same time the inner ring and outer ring can be detected, which greatly improves the work efficiency. At the same time, when detecting the rotation of the bearing, it can reduce the vibration and impact during the transmission process, thereby improving the detection accuracy.

[0028] 2. This utility model, through the installation groove, photoelectric sensor, vibration isolation pad, shock absorption ring and spring, can further reduce the vibration of the photoelectric sensor, so that the photoelectric sensor can remain stable when performing rotation detection, thereby improving the detection effect.

[0029] 3. This utility model, through the setting of fixing blocks, limiting plates and electromagnets, can fix the bearing from the side, which facilitates the simultaneous detection of the inner and outer rings of the bearing. At the same time, it can fix bearings of different sizes, which greatly improves the use effect. Attached Figure Description

Detailed Implementation

[0037] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0038] refer to Figure 1 and Figure 2 A bearing inner and outer ring machining deviation detection device includes a base 10, an mounting plate 11 fixedly mounted on the upper surface of the base 10, a fixing block 12 fixedly mounted on one side of the mounting plate 11, a plurality of limiting plates 13 of varying sizes fixedly mounted on the surface of the fixing block 12, and an electromagnet 14 fixedly mounted inside the limiting plate 13 for fixing the bearing.

[0039] Specifically, the bearing is placed on the surface of the limiting plate 13 and then magnetically fixed by the electromagnet 14. The limiting plates 13 are set from small to large to facilitate the installation of bearings of different sizes, which is practical.

[0040] Further reference Figure 1 and Figure 2 The mounting plate 11 has a through first groove 15 inside, and a slide plate 16 is slidably installed inside the first groove 15. An arc-shaped support plate 17 is fixedly installed on the upper surface of the slide plate 16 near the fixing block 12. A fixing plate 18 is fixedly installed on the side of the mounting plate 11 away from the fixing block 12. A threaded rod 19 is rotatably installed inside the fixing plate 18. The bottom of the threaded rod 19 is fixed to the slide plate 16 and rotates in cooperation with it.

[0041] Specifically, when installing larger bearings, the threaded rod 19 can be rotated to move the slide plate 16 upwards, and the bearing can be lifted by the support plate 17. This supports the larger bearing, making it easier to fix the bearing and reducing labor intensity.

[0042] Further reference Figure 3 and Figure 4 A first lead screw 21 is rotatably installed in the inner cavity of the base 10. A knob 22 is fixedly installed on one side of the first lead screw 21. A second sliding groove 20 is opened on the upper surface of the base 10. A movable plate 23 is threaded on the surface of the first lead screw 21.

[0043] Specifically, in use, rotating the knob 22 causes the first lead screw 21 connected to it to rotate, which in turn causes the moving plate 23 to slide in the second slide groove 20, so that the detection device on the moving plate 23 is close to the bearing for detection. The moving plate 23 is a certain distance away from the bearing, which facilitates the fixing of the bearing.

[0044] Further reference Figure 1 and Figure 4A drive gear 24 is rotatably mounted on one side surface of the movable plate 23. A rocker arm 26 is eccentrically mounted on the surface of the drive gear 24, and a driven gear 25 that rotates on the surface of the movable plate 23 is meshed on the upper surface of the drive gear 24.

[0045] Specifically, during use, the rocker arm 26 rotates to drive the drive gear 24, which in turn drives the driven gear 25. This avoids the vibration generated by using a motor, which could cause errors in the detection results. At the same time, the two gears experience more balanced forces during transmission. This balanced force helps reduce vibration and impact during transmission, thereby improving detection accuracy.

[0046] Further reference Figure 4 and Figure 6 The movable plate 23 has a rotating shaft 27 driven by a driven gear 25 rotatably mounted inside. One end of the rotating shaft 27 is fixedly mounted with a mounting box 28. The mounting box 28 has two second lead screws 29 threaded inside. A third slide groove 30 is opened on one side of the mounting box 28. A detection plate 31 that slides in the third slide groove 30 is threaded on the surface of the second lead screws 29. A photoelectric sensor 33 is provided on the opposite side of the detection plate 31 and the bearing. The photoelectric sensor 33 is prior art and will not be described in detail in this solution. It is used to detect the inner cavity and outer ring of the bearing.

[0047] Specifically, in use, the movable plate 23 moves the photoelectric sensor 33 to correspond with the bearing. The upper second lead screw 29 is adjusted to move the detection plate 31 up and down, adjusting the photoelectric sensor 33 to correspond with the outer ring of the bearing and maintaining a suitable detection height. Similarly, the lower second lead screw 29 is adjusted to correspond the photoelectric sensor 33 with the inner ring of the bearing. After adjustment, the mounting box 28 rotates, causing the two photoelectric sensors 33 to rotate around the inner and outer rings of the bearing respectively, thereby enabling the entire bearing to be detected. The inner and outer rings can be detected simultaneously, greatly improving work efficiency and detection accuracy.

[0048] Furthermore, refer to Figure 5 The detection plate 31 has an internal mounting groove 32. The photoelectric sensor 33 is fixedly installed inside the mounting groove 32, and a vibration isolation pad 34 is provided between the photoelectric sensor 33 and the mounting groove 32. A shock-absorbing ring 35 is sleeved on the surface of the photoelectric sensor 33, and a spring 36 is fixedly installed between the shock-absorbing ring 35 and the inner wall of the mounting groove 32.

[0049] Specifically, the vibration isolation pad 34 is used to dampen the photoelectric sensor 33, and the spring 36 and the damping ring 35 are used to further dampen the photoelectric sensor 33, so that the photoelectric sensor 33 can remain stable when performing rotation detection and improve the detection effect.

[0050] Furthermore, a shock-absorbing pad 37 is fixedly installed on the lower surface of the base 10 for overall shock absorption of the equipment, thereby further improving the detection accuracy.
