Abstract
Description
Technical Field
[0001] This utility model relates to a detection device, and more particularly to a bearing center groove position difference detection device. Background Technology
[0002] As a key component in mechanical transmission and support, bearings directly affect the stability and lifespan of the entire mechanical system. Among these components, the positional accuracy of the bearing grooves is a crucial indicator of bearing quality. Geometric parameters such as diameter tolerance (radial runout), roundness, and profile deviation directly impact the bearing's operational smoothness. If the positional accuracy of the bearing grooves fails to meet design requirements, it can lead to uneven stress on the balls during operation, cage misalignment, and consequently, vibration, noise, and even accelerated premature bearing fatigue failure. Therefore, accurately detecting the positional accuracy of the grooves during bearing production is a critical step in ensuring product quality.
[0003] However, existing trench inspection devices have revealed some significant problems in practical use. The adjustment mechanism typically uses bolt tightening to adjust the position of the support plate. This traditional method is not only cumbersome but also requires repeated adjustments to both sides of the device to ensure the accuracy of the inspection reference surface. The adjustment process demands high concentration and is susceptible to errors due to improper human operation, severely impacting inspection efficiency and accuracy. Especially in the context of mass production and high-precision inspection requirements, the inefficiency of this adjustment method has become a bottleneck restricting production. Therefore, a more efficient and convenient inspection device is urgently needed to solve this technical challenge. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.
[0027] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0028] Existing adjustment mechanisms typically use bolt tightening to adjust the position of the pallet. This traditional method is not only cumbersome but also requires repeated adjustments to both sides of the device to ensure the accuracy of the detection reference plane. Therefore, to solve the above problems, this paper proposes the following technical solution:
[0029] Reference Figures 1-4As shown, a bearing center groove position difference detection device includes: a detection bracket 1, a linkage frame 2, and a detection gauge 3. The detection bracket 1 is installed at the front end of the linkage frame 2, and the detection gauge 3 is installed at the rear end of the linkage frame 2. The linkage frame 2 includes a detection rod 26 and a slider 24. The detection rod 26 is movably connected to the surface of the slider 24. A slide rail 23 is provided on the top of the slider 24, and the slide rail 23 is slidably engaged with the slider 24. The slider 24 is movably connected to the detection rod of the detection gauge 3. A base 22 is provided at the bottom of the slide rail 23, and a bracket on the surface of the base 22 is also connected to the detection gauge 3.
[0030] The main components of this testing device consist of two parts: a testing bracket 1 and a linkage frame 2. The testing bracket 1 supports the inner and outer rings of the bearing. When its protruding testing rod 26 engages and rotates with the inner and outer rings of the bearing, if an error occurs, the pointer of the testing gauge 3 will rotate accordingly.
[0031] The linkage frame 2 consists of a base 22, a slide rail 23, a slider 24, and a limiting block 25. The base 22 serves as the bottom support, and a detection bracket 1 is mounted on its surface. The slide rail 23 is located at the rear end of the linkage frame 2, its bottom fixed to the base 22, and its top groove mates with the slider 24. A limiting block 25 is mounted on the side of the slide rail 23, and a detection rod 26 is installed inside to detect the error during bearing ring rotation. When the detection rod 26 moves, it presses against the slider 24, causing the slider 24 to deflect, which in turn moves the pointer of the detection rod on the gauge 3. In addition, the device is equipped with a protective cover 21 to prevent dust from affecting the internal components.
[0032] The structure of the testing bracket 1 includes components such as a base plate 11, a support plate 12, a limiting base 13, a sliding groove 18, a pad 16, a limiting bolt 14, and a drive shaft 15. The support plate 12 is mounted on the surface of the base plate 11, and the bottom of the support plate 12 is connected to the limiting base 13. The limiting base 13 slides into the double sliding grooves 18 on the surface of the base plate 11. One sliding groove 18 is used for sliding engagement with the limiting base 13, while the other is nested into the pad 16. The pad 16 is connected to the limiting base 13 by threads, and the threads on both sides of the limiting base 13 are symmetrically distributed. A drive shaft 15 is mounted on one end of the limiting bolt 14. The drive shaft 15 has a polygonal prism structure, and its center is twisted via a limiting buckle 17. This allows for quick adjustment of the range of motion of the support plate 12. During installation, the limiting buckle 17 is engaged with the groove in the middle of the limiting base 13.
[0033] The device has been optimized, employing a linear motion drive mechanism of the detection rod 26 to propel the slider 24. The slider 24 directly engages with the detection gauge 3, effectively improving detection accuracy and simplifying operation. The support plate 12 of the detection bracket 1 rotates via the limit buckle 17, driving the drive shaft 15 on the limit bolt 14 to twist. This threaded displacement engages the pad 16 with the limit base 13 and the slide groove 18, achieving rapid positioning. Pressure can be independently adjusted on both sides, resulting in greater stability during locking.
[0034] This device controls the limit bolts 14 on both sides to make rapid adjustments through the limit buckle 17. The limit buckle 17 is connected to the limit bolts 14 on both sides respectively, which can simultaneously make the limit bolts 14 clamp the pad 16 and the limit base 13 for rapid positioning, or make individual fine adjustments, which is more convenient when making horizontal adjustments.
[0035] The above description only outlines the basic principles and preferred embodiments of this utility model. Those skilled in the art can make many changes and improvements based on the above description, and these changes and improvements should fall within the protection scope of this utility model.
[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
