Description

Technical Field

[0001] The utility model relates to the technical field of precision detection equipment for parts, in particular to a bearing clearance detection tooling. Background Technique

[0002] In the fields of mechanical manufacturing and maintenance, as a key transmission component, the clearance of a bearing directly affects the running precision, stability and service life of equipment. Therefore, accurate detection of the bearing clearance is an important link to ensure the performance of the equipment. However, there are many deficiencies in traditional bearing clearance detection methods, such as low detection precision, poor stability, weak adaptability, etc., which are difficult to meet the requirements of modern industry for high-quality and high-efficiency detection.

[0003] First of all, traditional detection methods often rely on manual operation and simple measuring tools, such as vernier calipers, feeler gauges, etc. These tools are easily affected by human factors and environmental factors during the measurement process, resulting in inaccurate measurement results. At the same time, due to the different specifications and shapes of different bearings, traditional tools are often difficult to adapt to diverse detection requirements, increasing the difficulty and cost of detection.

[0004] Secondly, there are also major problems with traditional detection methods in terms of stability. Since bearings are usually installed inside the equipment and the working environment is complex and changeable, such as high temperature, high pressure, vibration, etc., these factors will all affect the measurement of the bearing clearance. And traditional detection methods often lack effective stabilizing mechanisms, resulting in the bearing being prone to movement or tilting during the measurement process, further reducing the accuracy of the measurement results. For this reason, we provide a bearing clearance detection tooling. Content of the Utility Model

[0005] In order to solve the above problems, the utility model proposes a bearing clearance detection tooling to more precisely solve the problems raised in the above background technique.

[0006] The utility model is realized through the following technical solutions:

[0007] The utility model proposes a bearing clearance detection tooling, including a chassis, and a telescopic structure is connected to the upper end surface of the chassis;

[0008] The chassis is provided with an annular frame through the telescopic structure. A T-shaped sliding groove is opened on the upper end surface of the annular frame. A T-shaped arc block is slidably connected to the inner wall of the T-shaped sliding groove. A limiting torsion fixing component is connected to the upper end surface of the T-shaped arc block;

[0009] The T-shaped arc block is provided with a detection ruler through the limiting torsion fixing component. A stabilizing mechanism is connected to the upper end surface of the chassis;

[0010] The bearing main body is placed on the upper end surface of the chassis through the stabilizing mechanism.

[0011] Furthermore, the stabilizing mechanism includes a strip-shaped placement groove opened on the upper end surface of the chassis. A horizontal fixing rod is fixedly connected between the two end walls of the strip-shaped placement groove. A first spring is sleeved around the horizontal fixing rod. A moving sleeve block is slidably sleeved around the horizontal fixing rod and is slidably connected to the inner wall of the strip-shaped placement groove. An arc-shaped outer supporting plate is fixedly connected to the upper end surface of the moving sleeve block.

[0012] Furthermore, the telescopic structure includes a hollow rod fixedly connected to the upper end surface of the chassis and a solid insertion rod fixedly connected to the lower end surface of the annular frame. The solid insertion rod is inserted into the inner wall of the hollow rod. A second spring is fixedly installed on the upper end surface of the chassis and is located inside the hollow rod. The upper end of the second spring is fixedly connected to the lower end of the solid insertion rod.

[0013] Furthermore, the limiting and twisting fixing component includes an n-shaped plate fixedly connected to the upper end surface of the T-shaped arc block. A twisting fixing screw is threadedly connected to the top end of the n-shaped plate.

[0014] Furthermore, the inspection ruler is clamped and slides inside the n-shaped plate. The threaded section of the twisting fixing screw penetrates through the top end of the n-shaped plate and is in contact connection with the surface of the inspection ruler.

[0015] Furthermore, one end of the first spring is fixedly connected to the end wall of the strip-shaped placement groove, and the other end of the first spring is fixedly connected to one end surface of the moving sleeve block.

[0016] Advantages of the present utility model:

[0017] Through the exquisitely designed stabilizing mechanism and limiting and twisting fixing component, the present utility model significantly improves the accuracy and stability of bearing clearance detection. The arc-shaped outer supporting plate in the stabilizing mechanism can closely fit the outer surface of the bearing body, providing a stable supporting force to prevent the bearing body from moving or tilting during the detection process. At the same time, the limiting and twisting fixing component firmly fixes the inspection ruler on the T-shaped arc block through the twisting fixing screw, ensuring that the inspection ruler does not shake or shift during the measurement process, thereby guaranteeing the accuracy of the measurement result. This design makes the detection of bearing clearance more reliable and provides strong support for the quality control and performance evaluation of bearings.

[0018] Through the design of the telescopic structure and the T-shaped chute, the present utility model enhances the adaptability and flexibility of the tooling. The telescopic structure allows users to conveniently adjust the height and position of the annular frame according to the size and shape of the bearing body to meet the detection requirements of different specifications of bearings. The combination of the T-shaped chute and the T-shaped arc block enables the inspection ruler to be flexibly installed at different positions of the bearing body to achieve a comprehensive detection of the bearing clearance.
