Description

Technical Field

[0001] This utility model belongs to the field of bearing ring inspection technology, and in particular relates to a tooling for inspecting the inner flange of the outer ring of a bearing. Background Technology

[0002] A rolling bearing is a precision mechanical component that transforms the sliding friction between a rotating shaft and its housing into rolling friction, thereby reducing frictional losses. A rolling bearing generally consists of four parts: an inner ring, an outer ring, rolling elements, and a cage. The inner ring mates with the shaft and rotates with it; the outer ring mates with the bearing housing and provides support; the rolling elements are evenly distributed between the inner and outer rings by the cage, and their shape, size, and number directly affect the performance and lifespan of the rolling bearing; the cage ensures the even distribution of the rolling elements, guides their rotation, and provides lubrication.

[0003] Currently, depending on the type of bearing, the rolling elements generally include ball bearings, cylindrical bearings, and tapered bearings. To ensure the stability of the rolling elements, for example, cylindrical roller bearings typically have flanges on the inner side of the outer ring to limit their position. These flanges are usually milled to ensure the rolling elements are properly positioned within the bearing. Therefore, the flatness and dimensional accuracy of the inner surface of the flange are crucial for the effective placement of the rolling elements. In existing technology, the inspection of the inner side of the outer ring of bearings with flanges is generally done manually, combining visual inspection with tactile feedback on the flange side. This method is time-consuming, labor-intensive, and impractical. Furthermore, the inspection error is uncontrollable due to varying manual techniques, affecting the quality of the workpiece and potentially leading to poor assembly or tight fit, thus failing to meet usage requirements.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Examples, such as Figures 1-5As shown, a fixture for inspecting the inner flange of a bearing outer ring includes a fixture body. The fixture body includes an L-shaped upright frame 1 to ensure the stability of the device. An inclined adjustment groove 1a is provided inside the upright frame 1a, and a bottom support assembly 2 is installed within the adjustment groove 1a. Using the adjustment groove 1a, the position of the bottom support assembly 2 can be adjusted according to the workpiece of different sizes to be inspected, providing convenient conditions for the stable installation of the workpiece. An inner buckling detection assembly 3 is installed above the upright frame 1. The inner buckling detection assembly 3 includes a support frame 31, and a T-shaped mounting frame 32 is installed on the support frame 31. The mounting frame 32 has two sides above it. A sleeve 321 contains a metal sheet 33. An L-shaped carrier plate 34 is positioned above the metal sheet 33. A sleeve 321 is also positioned below the carrier plate 34, allowing the metal sheet 33 to be inserted and secured with bolts. The selected metal sheet 33 possesses a certain degree of elasticity; it bends under force and returns to its original shape when the force is removed. A mounting screw 35 is mounted on the carrier plate 34, penetrating the support frame 1. One side of the mounting screw 35 is limited by a nut, and a gap is left between the mounting screw 35 and the support frame 1. Thus, when the first ball 37... When a deviation occurs during the inspection of the workpiece's flange, the mounting screw 35 will shift, causing the metal sheet 33 to bend and the carrier plate 34 to swing. This action acts on the connecting plate 5, which then contacts the measuring gauge 43, causing its reading to change. This visually reflects the flange's runout, completing the inspection. The end of the mounting screw 35 is equipped with an L-shaped extension bracket 36, which is L-shaped with the mounting screw 35. A first ball bearing 37 is located on one side of the extension bracket 36, and a connecting plate 5 with an obtuse angle is located on one side of the carrier plate 34. The first ball bearing 37 can contact the inner side of the workpiece's flange. During use, the... The workpiece is placed on the bottom support assembly 2, and the first ball bearing 37 is in contact with the inner side of the retaining edge. Then, the workpiece is rotated manually. When the size of the retaining edge changes, the connecting plate 5 swings under the support of the metal plate 33 and contacts the meter head of the measuring instrument 43, causing the meter head to swing and thus changing the reading. This design makes the detection process more intuitive, simple and convenient to operate, and highly functional. A measuring assembly 4 is set on one side of the stand 1. The measuring assembly 4 supports the swing of the connecting plate 5 to change the reading in the measuring instrument 43, thereby making the detection work more intuitive, reducing errors, improving the work process, and meeting the usage requirements.

[0021] In the above process: the established bottom support component 2 not only provides stable support for the workpiece, ensuring the smooth progress of the inspection work, but also ensures the smoothness of its rotation and adjustment process, improving the work process and meeting the usage requirements; the established inner buckle detection component 3, on the one hand, cooperates with the bottom support component 2 to limit the position of the workpiece, and on the other hand, can conveniently detect its inner side edge, and feed back the dimensional information to the measuring component 4, realizing a direct display of the inspection process, improving the work process and meeting the usage requirements; this device is reasonably designed, simple in structure, easy to process, and can conveniently detect the size and runout of the inner side edge of the workpiece, reducing labor intensity, improving the work process, ensuring the accuracy of the inspection results, improving the forming quality of the workpiece, ensuring the use effect, and effectively meeting the usage requirements.

[0022] To ensure the stability of the workpiece during the inspection process and guarantee the accuracy of the inspection results, the bottom support assembly 2 includes a mounting rod 21 adapted to the adjustment groove 1a. A locking nut 22 is provided on the rear side of the mounting rod 21, and a sleeve 23 is provided on the outer periphery of the front side of the mounting rod 21. A fastening screw 24 is provided on one side of the sleeve 23, and a second ball bearing 25 is provided on the outer side of the sleeve 23. The arrangement direction of the second ball bearing 25 is perpendicular to the position of the fastening screw 24. Specifically, for workpieces of different sizes to be inspected, the position of the mounting rod 21 is first adjusted, and then tightened using the locking nut 22, so that... The outer periphery of the workpiece contacts the bottom support component 2, and the inner side of the upper part of the workpiece contacts the inner buckle detection component 3. This provides convenient conditions for manually rotating the workpiece. Based on the external setting of the mounting rod 21, the position of the sleeve 23 is adjusted, especially so that the second ball 25 can be perpendicular to the workpiece, ensuring the smoothness of its rotation. At the same time, the longitudinal position of the sleeve 23 is adjusted according to the outer periphery width of the workpiece, and its position is tightened and limited by the fastening screw 24. On the one hand, the external setting can further improve the support for the workpiece and ensure stability, and on the other hand, it provides the prerequisite for its smooth rotation and meets the usage requirements.

[0023] To provide a clear visual demonstration of the internal buckling detection component 3 during the detection process, the measuring component 4 includes a T-shaped mounting base 41 with a connecting base 42 on the mounting base 41. A measuring gauge 43 is mounted on the connecting base 42, with its end contacting the outer end face of the connecting plate 5. Specifically, the mounting base 41 and connecting base 42 facilitate the stable installation of the measuring gauge 43. The selected measuring gauge 43 can be a dial indicator or a micrometer. When the workpiece is placed on the bottom support component 2, the internal buckling detection component 3 abuts against the edge of the workpiece. When the workpiece is rotated, and the dimensions fluctuate, the first ball bearing 37 and the mounting screw 35 are activated, causing longitudinal shaking and shaking of the connecting plate 5. This action then acts on the gauge head of the measuring gauge 43. By observing the changes in the reading on the measuring gauge 43, the forming effect of the workpiece can be judged. The operation is simple and convenient, and the functionality is strong.

[0024] To further improve the rationality of the device setup, the connecting seat 42 includes a sliding sleeve 421 vertically sleeved on the mounting seat 41. An L-shaped plate 422, horizontally mounted and designed in an L-shape, is provided on the sliding sleeve 421. A rotating sleeve 423 for supporting the measuring instrument 43 is provided on the short side of the L-shaped plate 422. Specifically, the mounting seat 41 is T-shaped, and its lower part can support and limit the position of the sliding sleeve 421 to prevent it from shifting. Of course, bolts can also be used for further tightening. The L-shaped plate 422 and the sliding sleeve 421 are also installed using an insert connection. The purpose is to allow for the selection of rotating sleeves 423 of different specifications for measuring instruments 43 of different sizes. To enhance the functionality of the device, the lower part of the rotating sleeve 423 can be rotated and adjusted relative to the L-shaped plate 422. In other words, there is a certain degree of damping between the rotating sleeve 423 and the L-shaped plate 422 to facilitate easy positioning. Above the rotating sleeve 423, there is a component similar to a clamping locking device to position the measuring gauge 43. During use, it is necessary to ensure that the rotating sleeve 423 stably clamps the measuring gauge 43, and then adjust the rotating sleeve 423 so that the measuring gauge 43 is arranged perpendicularly to the connecting plate 5. This ensures that it can provide real-time feedback on the dimensional measurement process of the inner buckle detection component 3 during operation, ensuring the rationality of the device setup and meeting the usage requirements.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
