Description

Technical Field

[0001] This application relates to the technical field of bearing detection, and particularly to a precision bearing detection fixture. Background Art

[0002] The outer ring raceway of a precision bearing refers to the groove inside the outer ring of the bearing. The design and manufacturing of this raceway have a crucial impact on the performance and lifespan of the bearing. It is mainly used to accommodate rolling elements (such as rollers) and enable them to roll freely within the bearing. The raceway provides an accurate track for the rolling elements, ensuring that they can roll evenly within the bearing, thereby effectively reducing friction and wear.

[0003] During the manufacturing process, strict inspection and quality control of the raceway are required to ensure that the performance and lifespan of the bearing meet the expected goals.

[0004] Currently, when inspecting the raceway inside the outer ring of a precision bearing, inspectors need to observe through a magnifying glass and rotate the bearing during the observation to check whether the thread pattern of the raceway is correct and complete. When the diameter of the precision bearing is too small, it is inconvenient for the inspector to rotate the bearing. Utility Model Content

[0005] To solve the problem of bearing raceway detection in the background art, this application provides a precision bearing detection fixture.

[0006] A precision bearing detection fixture provided by this application adopts the following technical solutions:

[0008] By adopting the above technical solution, with the combined design of a base that is convenient to hold and a rotating table, inspectors can conveniently rotate small-sized precision bearings for comprehensive and accurate detection. This design avoids the inconvenience of rotation in traditional detection methods and improves the detection efficiency and operation convenience.

[0009] Preferably, a clamping surface that is convenient to pick up is provided on the base.

[0010] By adopting the above technical solution, the clamping surface is designed to enable inspectors to hold and operate the fixture more conveniently, improving the convenience of use.

[0011] Preferably, anti-slip patterns are provided on the rotating table.

[0012] By adopting the above technical solution, the anti-slip patterns increase the friction between the operator and the rotating table, facilitating the operator to rotate the rotating table for convenient inspection.

[0013] Preferably, a magnet for adsorbing the bearing is arranged inside the rotating table.

[0014] By adopting the above technical solution, the magnet can ensure that the bearing is firmly adsorbed in the limiting groove, avoiding accidental slipping of the bearing during the detection process, and further enhancing the safety of the detection.

[0015] Preferably, the base is detachably connected to the rotating table.

[0016] By adopting the above technical solution, the fixture is easier to store and carry, and at the same time, it is convenient to replace damaged parts, extending the service life of the fixture.

[0017] Preferably, an illuminating device for facilitating the observation of the raceway is further arranged in the limiting groove.

[0018] By adopting the above technical solution, the illuminating device can provide sufficient light to ensure that the raceway is clearly visible, thereby improving the accuracy and reliability of the detection.

[0019] Preferably, a locking structure for fixing the bearing is rotatably arranged on one side of the rotating table close to the limiting groove.

[0020] By adopting the above technical solution, the locking structure further enhances the stability of the bearing during the detection process and prevents accidental movement or detachment of the bearing.

[0021] Preferably, the locking structure includes a bolt rotatably connected to the rotating table, and a locking plate and a spring are sleeved between the head of the bolt and the rotating table. The locking plate is located on one side close to the head of the bolt, one end of the spring abuts against the rotating table, and the other end abuts against the locking plate.

[0022] By adopting the above technical solution, the locking plate and the spring can ensure that the bearing always maintains a stable state during the detection process.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Features such as a base convenient for holding, a rotatable rotating table, a stable bearing placement design, an anti-slip and locking structure, etc. achieve comprehensive, convenient, stable and accurate detection of the outer raceway of small-sized precision bearings, significantly improving the detection efficiency and quality, while ensuring safety during the operation process and extending the service life of the fixture.

[0028] The following further describes the present application in detail Figure 1 - with reference to the attached Figure 2 drawings.

[0029] An embodiment of the present application discloses a precision bearing detection fixture.

[0030] Referring to Figure 1 , a precision bearing detection fixture includes a base 1 and a rotating table 2. The base 1 is designed in a shape convenient for holding by hand, and the rotating table 2 is rotatably connected thereto. A limiting groove 3 is provided at one end of the rotating table 2 away from the base 1, and the size of the limiting groove 3 matches that of the bearing to be detected, ensuring that the bearing can be stably placed in the limiting groove 3. During use, the inspector only needs to place the bearing in the limiting groove 3 and then observe the outer raceway of the bearing by rotating the rotating table 2.

[0031] Referring to Figure 1 , the base 1 is provided with a clamping surface 11 convenient for taking, and the clamping surface 11 is provided in two and arranged oppositely, facilitating the inspector to firmly hold the base 1 for operation. In addition, anti-slip patterns 21 are added to the surface of the rotating table 2, increasing the friction between the operator and the rotating table 2 and facilitating the operator to rotate the rotating table 2 for inspection.

[0032] Referring to Figure 1 , a magnet for adsorbing the bearing is provided inside the rotating table 2, enabling the bearing to be more stably placed in the limiting groove 3 and preventing accidental slipping during the detection process.

[0033] Referring to Figure 1 and Figure 2 , the base 1 and the rotating table 2 are designed to be detachably connected. A connecting bearing 4 is provided on the base 1. The outer ring of the connecting bearing 4 is fixedly connected to the base 1, and the rotating table 2 is press-fitted into the inner ring of the bearing. This not only facilitates storage and transportation but also makes the fixture easier to maintain and replace components.

[0034] Referring to Figure 1 , a lighting device 5 for facilitating the observation of the raceway is further provided in the limiting groove 3, including a small LED lamp provided inside the limiting groove 3, providing sufficient light to ensure that every detail of the raceway is clearly visible during detection. This improvement is particularly applicable to a dim environment, improving the accuracy and reliability of detection.

[0035] Referring to Figure 1, on one side of the rotating table 2 close to the limit groove 3, a locking structure 6 is further provided. The locking structure 6 includes a bolt 61 rotatably connected to the end face of the rotating table 2 close to the limit groove 3. A locking plate 62 and a spring 63 are installed between the head of the bolt 61 and the rotating table 2. The locking plate 62 is on the side close to the head of the bolt 61, and one end of the spring 63 abuts against the rotating table 2, and the other end abuts against the locking plate 62. By rotating the bolt 61, the pressing force between the locking plate 62 and the bearing can be adjusted, so as to achieve stable locking of the bearing.

[0036] The implementation principle of the embodiment of the present application is as follows: The inspector can easily rotate the rotating table 2 connected to the base 1 by holding the base 1, and then rotate the outer ring of the bearing placed in the limit groove 3. This design greatly simplifies the detection process of small-sized precision bearings and improves the detection efficiency and accuracy.
