Description

Technical Field

[0001] This utility model relates to the field of bearing testing tooling technology, specifically a template for testing the depth of the retaining groove on the outer diameter of a bearing. Background Technology

[0002] Currently, with the advancement of technology in the international bearing industry, customers have increasingly higher requirements for product quality, with dimensional and positional accuracy demands rising simultaneously. How to quickly and accurately inspect product dimensions and positional accuracy has become a pressing research topic for all bearing manufacturers. A retaining groove on the outer diameter of the bearing is a common bearing design used to install a retaining ring. When the entire bearing is installed in the gearbox, the retaining ring mates with the flange of the bearing housing to achieve axial positioning. Therefore, the depth requirement of the retaining groove is crucial. The existing method for measuring the retaining groove depth uses vernier calipers, and the reading is compared with the tolerance required by the drawing to see if it is within the required range. This method is inefficient and has a relatively large error. Therefore, it is necessary to research and design a measuring tool that can quickly and accurately measure the depth of the retaining groove, thereby improving inspection efficiency and ensuring product quality. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides a template for detecting the depth of the retaining groove on the outer diameter of a bearing. It can detect the depth of the retaining groove on the outer diameter of the bearing, avoid errors in data reading, and determine whether the position is qualified by simply measuring the fit between the gauge and the retaining groove depth. It is convenient and quick, and improves the testing efficiency of the product.

[0004] To achieve the above objectives, this utility model provides a template for detecting the depth of the retaining groove on the outer diameter of a bearing, comprising an upper limit measuring groove, a template body, and a lower limit measuring groove. There are two upper limit measuring grooves and two lower limit measuring grooves. Two upper limit measuring grooves are provided on one side of the template body, and two lower limit measuring grooves are provided on the other side. A first reference surface is formed between the two upper limit measuring grooves; a second reference surface is formed between the two lower limit measuring grooves. An upper limit stop is formed between the upper limit measuring groove and the edge of the template body; the distance between the two upper limit stopes is the upper limit gauge; a lower limit stop is formed between the lower limit measuring groove and the edge of the template body; the distance between the two lower limit stopes is the lower limit gauge; the outer diameter of the retaining groove intersects between the upper limit gauge and the lower limit gauge.

[0005] Furthermore, the upper limit measuring groove is provided with a first retraction groove on both sides of the groove bottom.

[0006] Furthermore, a second retraction groove is provided on both sides of the bottom of the lower limit measuring groove.

[0007] Furthermore, the template body is an "I" shaped template.

[0008] Furthermore, the upper limit measuring groove is a rectangular groove.

[0009] Furthermore, the lower limit measuring groove is a rectangular groove.

[0010] Furthermore, the upper limit stop is a rectangular stop.

[0011] Furthermore, the lower limit stop is a rectangular stop.

[0012] Furthermore, the first reference surface is pressed against the bearing reference end surface.

[0013] Furthermore, the second reference surface is pressed against the bearing reference end face.

[0014] The beneficial effects of this utility model are as follows: by designing a template for detecting the depth of the retaining groove, the depth of the retaining groove on the outer diameter of the bearing can be detected, avoiding errors in data reading. The positional accuracy can be judged simply by the degree of fit between the measuring gauge and the retaining groove depth, which is convenient, quick and easy, and improves the testing efficiency of the product.

[0016] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] To solve the above problems, the technical solution of the present invention is to redesign a test template, which is made of GCr15 material to enhance wear resistance. The template includes a lower limit gauge 341 and an upper limit gauge 331, which are respectively used to detect the upper limit dimension and the lower limit dimension of the depth of the stop groove 420. The reference surface of the template is used to match the reference end face of the bearing to ensure the measurement accuracy. In addition, 4 relief grooves are arranged in the template gauge, which facilitates the grinding and root clearing in the template manufacturing process and ensures the precision of the gauge. This gauge is used to detect the depth of the stop groove 420 of the product. When the upper limit gauge 331 is larger than the maximum outer diameter of the stop groove 420 (i.e., the point with the smallest depth), and the lower limit gauge 341 is smaller than the minimum outer diameter of the stop groove 420 (i.e., the point with the largest depth), it indicates that the position degree is within the qualified range and the product is a qualified product. If the upper limit gauge 331 is smaller than the maximum outer diameter of the stop groove 420 (i.e., the point with the smallest depth) or the lower limit gauge 341 is larger than the minimum outer diameter of the stop groove 420 (i.e., the point with the largest depth), it indicates that the depth of the stop groove 420 is out of tolerance and the product is an unqualified product. Applying this method to detect the depth of the stop groove 420 can quickly and efficiently detect the depth of the stop groove 420, improve the detection efficiency, and ensure the accuracy of the detection result.

[0018] As Figure 1-4 shown, in an embodiment of the present utility model, a template for detecting the depth of the stop groove 420 on the outer diameter of a bearing includes two upper limit measuring grooves 100, a template body 300, and two lower limit measuring grooves 200. Two upper limit measuring grooves 100 are arranged on one side of the body, and two lower limit measuring grooves 200 are arranged on the other side. A first reference surface 310 is formed between the two upper limit measuring grooves 100. A second reference surface 320 is formed between the two lower limit measuring grooves 200. An upper limit rib 330 is formed between the upper limit measuring groove 100 and the edge of the template body 300. The distance between the two upper limit ribs 330 is the upper limit gauge 331. A lower limit rib 340 is formed between the lower limit measuring groove 200 and the edge of the template body 300. The distance between the two lower limit ribs 340 is the lower limit gauge 341. The outer diameter of the stop groove 420 is between the upper limit gauge 331 and the lower limit gauge 341.

[0019] It should be noted that a product in which the outer diameter of the stop groove 420 is between the upper limit gauge 331 and the lower limit gauge 341 is a qualified product.

[0020] In an embodiment, both sides of the groove bottom of the upper limit measuring groove 100 are provided with first relief grooves 110.

[0021] In an embodiment, both sides of the groove bottom of the lower limit measuring groove 200 are provided with second relief grooves 210.

[0022] In an embodiment, the template body 300 is an "I"-shaped template.

[0023] In one embodiment, the upper limit measuring groove 100 is a rectangular groove.

[0024] In one embodiment, the lower limit measuring groove 200 is a rectangular groove.

[0025] In one embodiment, the upper limit stop 330 is a rectangular stop.

[0026] In one embodiment, the lower limit stop 340 is a rectangular stop.

[0027] In one embodiment, the first reference surface 310 is close to the bearing reference end surface 410.

[0028] The above-mentioned template is used to test the depth of the 420mm retaining groove on the outer diameter of a bearing. Figure 2 The bearing shown has a stop groove 420 on its outer diameter. The distance between the stop groove 420 and the outer diameter of the bearing is the depth of the stop groove 420. Figure 1 The test template includes a first reference surface 310 and a second reference surface 320, an upper limit gauge 331, and a lower limit gauge 341. The upper limit gauge 331 is the maximum outer diameter (i.e., minimum depth) of the stop groove 420 specified in the process, and the lower limit gauge 341 is the minimum outer diameter (i.e., maximum depth) of the stop groove 420 specified in the process. Applying the first reference surface 310 of the template close to the bearing reference surface, if the upper limit gauge 331 is larger than the maximum outer diameter (i.e., minimum depth) of the stop groove 420, meaning the gauge can pass through the stop groove 420, it indicates that the depth of the stop groove 420 is less than the upper limit of the process. Applying the second reference surface 320 of the template close to the bearing reference surface, if the lower limit gauge 341 is smaller than the minimum outer diameter (i.e., maximum depth) of the stop groove 420, meaning the gauge cannot pass through the stop groove 420, it indicates that the depth of the stop groove 420 is greater than the lower limit of the process. The results of these two measurements indicate that the depth of the stop groove 420 is between the upper and lower limits required by the process, and the product is qualified. Conversely, if the upper limit gauge 331 is less than the maximum outer diameter (i.e., the minimum depth point) of the stop groove 420, or if the lower limit gauge 341 is greater than the minimum outer diameter (i.e., the maximum depth point) of the stop groove 420, it indicates that the depth of the stop groove 420 exceeds the process requirements, and the product is defective. This measurement method is convenient to operate, highly accurate, and can significantly improve product testing efficiency.
