Description

Technical Field

[0001] This utility model relates to the field of testing mechanism technology, specifically a bearing end face testing mechanism. Background Technology

[0002] In the field of modern mechanical manufacturing and industrial production, bearings, as key basic components, are widely used in various mechanical equipment. Their quality directly affects the operating accuracy, stability and service life of the equipment. The flatness of the bearing end face and the assembly symmetry are important indicators for measuring the quality of bearings. Poor end face quality can lead to abnormal vibration and noise during bearing operation, and even accelerated wear, shortening the overall life of the bearing and its supporting equipment. Therefore, accurate inspection of the bearing end face has become a key link in ensuring the quality of bearing products.

[0003] Currently, common bearing end-face inspection technologies on the market mainly include manual visual inspection, traditional contact measurement, and some automated inspection equipment. Although traditional contact measurement can obtain certain dimensional data, the contact force between the measuring tool and the bearing end face is difficult to control precisely during the inspection process, which can easily damage the bearing surface. Furthermore, it cannot comprehensively detect issues such as the height difference between the inner and outer rings of the bearing and the press-fit tilt. While some automated inspection equipment improves inspection efficiency to a certain extent, the equipment structure is complex, the cost is high, and the inspection function is limited. It cannot simultaneously inspect both ends of the bearing and assess the assembly symmetry, making it difficult to achieve comprehensive control over the bearing press-fit quality. Therefore, a bearing end-face inspection mechanism is needed to solve the problems existing in the current technology. Utility Model Content

[0004] The purpose of this invention is to provide a bearing end face inspection mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bearing end face detection mechanism, comprising a U-shaped slide, wherein a double-sided detection mechanism is provided inside the U-shaped slide, the double-sided detection mechanism comprising a rotating ball, a pressure sensor, a rotating wheel, and a contacting roller, the rotating ball being slidably connected inside the U-shaped slide, the pressure sensor being disposed above a first suspension and a second suspension, the rotating wheel being fixed to the detection end of the pressure sensor, and the contacting roller being rotatably connected inside the rotating wheel.

[0006] Preferably, a first suspension bracket is fixed to the inner top wall of the U-shaped carriage, and a second suspension bracket is fixed to one side of the inner top wall of the U-shaped carriage located on the first suspension bracket. An arc-shaped positioning clamp is fixed to the upper end face of both the first suspension bracket and the second suspension bracket.

[0007] Preferably, the upper end of the pressure sensor is fixed with a mounting plate, and the lower end of the rotating slider is fixed to the upper surface of the mounting plate.

[0008] Preferably, the inner wall of the U-shaped carriage is provided with an adjustment groove, and the rotating ball is slidably connected in the adjustment groove of the U-shaped carriage.

[0009] Preferably, two of the arc-shaped positioning clamps in a set are symmetrically arranged, and a clamping opening is provided between the two symmetrical arc-shaped positioning clamps.

[0010] This utility model provides a bearing end face inspection mechanism, which has the following advantages compared with the prior art:

[0011] The double-sided inspection mechanism, utilizing the linkage of the fitting roller, rotating wheel, and pressure sensor, can accurately capture the height difference between the inner and outer rings of the bearing. Changes in pressure detection data directly reflect the flatness difference. Simultaneously, it can quickly determine the tilt of the inner and outer rings during press-fitting, enabling single-sided inspection. The sliding connection design of the rotating ball and the adjusting groove allows the double-sided inspection mechanism to be flexibly adjusted, facilitating the inspection of the top and bottom surfaces of the bearing. Simultaneously acquiring the axial height difference between the two end faces of the bearing allows for efficient assessment of assembly symmetry and comprehensive control over the bearing press-fitting quality.

[0012] By using the arc-shaped positioning clamp and clamping opening, the first and second suspension brackets inside the U-shaped carriage, together with the arc-shaped positioning clamp, form a clamping opening that fits the bearing, restricting the lateral position of the bearing, avoiding displacement caused by squeezing during the testing process, and ensuring testing accuracy.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a bearing end face detection mechanism, including a U-shaped slide 1. An adjusting groove 2 on the inner wall provides a sliding track for a rotating ball 4, allowing the double-sided detection mechanism to move along the bearing axial direction (vertical direction) to achieve double-sided detection of the bearing's top and bottom surfaces. The U-shaped slide 1 houses a double-sided detection mechanism 3, which includes a rotating ball 4, a pressure sensor 6, a rotating wheel 7, and a contact roller 8. The rotating ball 4 is slidably connected inside the U-shaped slide 1. The pressure sensor 6 is positioned above the first suspension bracket 9 and the second suspension bracket 10. When the bearing outer ring is higher than the inner ring... When the flatness is inconsistent, the movement of the contact roller 8 will cause the pressure sensor data to change. The data difference reflects the difference in flatness. By comparing the pressure data on both sides of the bearing (top and bottom), the assembly symmetry can be determined (such as whether it is tilted or the axial height difference exceeds the standard). The rotating wheel 7 is fixed to the detection end of the pressure sensor 6, and the contact roller 8 is rotatably connected inside the rotating wheel 7. The upper end of the pressure sensor 6 is fixed with the mounting plate 5, and the lower end of the rotating ball 4 is fixed to the upper end face of the mounting plate 5. The contact roller 8 senses the surface height change (such as flatness and tilt) by rolling and contacting the outer and inner ring end faces of the bearing.

[0020] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that a first suspension bracket 9 is fixed to the inner top wall of the U-shaped carriage 1, and a second suspension bracket 10 is fixed to the inner top wall of the U-shaped carriage 1 on one side of the first suspension bracket 9. Arc-shaped positioning clips 11 are fixed to the upper end faces of both the first suspension bracket 9 and the second suspension bracket 10. Two arc-shaped positioning clips 11 are symmetrically arranged in a set, and a clamping port 12 is provided between the two symmetrical arc-shaped positioning clips 11. The arc-shaped structure of the symmetrically arranged arc-shaped positioning clips 11 fits the outer ring of the bearing, restricts the lateral displacement of the bearing, and avoids data deviation caused by squeezing and sliding during testing.

[0021] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the inner wall of the U-shaped carriage 1 is provided with an adjustment groove 2, and the rotating ball 4 is slidably connected in the adjustment groove 2 of the U-shaped carriage 1.

[0022] The solution has the following working process: Before use, the bearing to be tested can be clamped in the clamping openings 12 between the arc-shaped positioning clamps 11 on the first suspension 9 and the second suspension 10. Since the clamping openings 12 are adapted to the bearing, the bearing can be horizontally arranged in the center of the double-sided testing mechanism 3. At the same time, the arc-shaped positioning clamps 11 restrict the lateral position, which can prevent the bearing from being squeezed and displaced during the flatness testing process of the double-sided testing mechanism 3, thus preventing the problem of decreased testing accuracy due to extrusion displacement.

[0023] During the double-sided inspection mechanism 3, the contact roller 8 slides over the outer and inner rings of the bearing. Since a pressure sensor 6 is installed above the contact roller 8 and the rotating wheel 7, when there is a height difference between the outer and inner rings of the bearing, the pressure detection data of the pressure sensor 6 changes when the contact roller 8 slides from the outer ring to the inner ring end face. The magnitude of the pressure detection data change can indicate the degree of flatness difference between the inner and outer rings of the bearing. When the contact roller 8 rolls over the outer and inner rings on the other side of the bearing, if the pressure detection data change of the pressure sensor 6 is inconsistent with the pressure detection data change of the inner and outer rings on the previous side, it can be determined that the inner and outer rings of the bearing are tilted during pressing. When the pressure sensor 6 changes data after the contact roller 8 slides over the inner and outer rings of the bearing, it indicates that the flatness of the bearing on one side is qualified. The double-sided detection mechanism 3 is slid along the adjustment groove 2 of the U-shaped slide 1 to the bottom surface of the bearing. Similarly, the contact roller 8 rolls over the inner and outer rings of the bearing bottom surface to achieve flatness detection. When the flatness of the bearing on both sides is qualified, the pressing quality of the bearing product can be confirmed. If the flatness change data of the bearing bottom surface is abnormal compared with the detection data of the bearing top surface, it indicates the symmetry of the bearing assembly. This double-sided detection can simultaneously obtain the axial height difference between the top and bottom surfaces of the bearing to ensure the symmetrical assembly of the bearing along the axial direction.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Although embodiments of this utility model have been shown and described, this does not limit the patent scope of this utility model.
