Abstract
Description
Technical Field
[0001] This utility model relates to a detection device, and in particular to a device for comparing the outer chamfer and outer diameter of a cylinder. Background Technology
[0002] Inspection of the outer chamfer of bearings is a crucial step in bearing quality control. It involves geometrically aligning the inspection rod with the bearing's outer chamfer to ensure the chamfer angle and transition radius meet design requirements. Existing inspection devices employ a double-sided inspection rod structure, achieving precise alignment with the chamfer contour through threaded adjustment.
[0003] When the diameter of the bearing being tested has a large range, length compensation is required by rotating the detection rod. However, the time consumption of long-stroke thread adjustment increases significantly, and the dynamic adaptation is insufficient. The chamfer parameters (such as angle and transition radius) of different bearing specifications are different. A single thread adjustment structure cannot meet the needs of synchronous adaptation of multiple parameters, and repeated debugging is required, which affects efficiency. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments 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] Currently, when the diameter of the bearing being tested has a large range, length compensation is required by rotating the testing rod. However, long-stroke thread adjustment significantly increases the time consumption and results in insufficient dynamic adaptation. Furthermore, the chamfer parameters (such as angle and transition radius) of bearings of different specifications vary, and a single thread adjustment structure cannot meet the requirements for simultaneous adaptation of multiple parameters, requiring repeated adjustments and affecting efficiency. Therefore, to solve the above problems, this paper proposes the following technical solution:
[0029] Reference Figures 1-4As shown, a cylindrical outer chamfer and outer diameter comparison device includes: a base 1, on the surface of which a first support 2, a second support 4, and a third support 6 are respectively mounted. The second support 4 is installed in the middle of the third support 6 and the first support 2, and a rotatable support 5 is provided on the surface of the second support 4. A gauge 3 is installed on the side of the first support 2, and the axis of the gauge 3 is opposite to the axis of the detection rod 7 installed in the through hole of the third support 6. The base 1 includes a clamping plate 11 and a seat body 12. The seat body 12 is movably connected to the clamping plate 11 through a first movable groove 14 provided on the side. A second movable groove 15 is provided in the middle of the seat body 12, which is nested with the first support 2, the second support 4, and the third support 6. A limiting side plate 16 is also installed on the surface of the seat body 12, which fits against the side of the first support 2, the second support 4, and the third support 6. A locking groove 13 is provided between the seat body 12 and the clamping plate 11.
[0030] In this embodiment, the main structure of the device includes a base 1, a first support 2 on the top of the base 1, and a gauge 3 installed inside the first support 2 for measuring error. A second support 4 is installed between the first support 2 and the third support 6. A rotatable support 5 is installed on the top of the second support 4 to prevent bearing damage. The third support 6 and a measuring rod 7 are located opposite the first support 2. The measuring rod 7 is opposite the gauge 3 and is used to measure the outer diameter and chamfer. A top rod parallel to the measuring rod 7 is also provided at the bottom of the third support 6. Its main function is to limit the support 5 on the top of the second support 4. When measuring the diameter, the support 5 is narrow on both sides for easy gripping. When measuring the chamfer, the support 5 is placed horizontally to stably support the bearing on both sides, reducing errors during rotation measurement.
[0031] To improve the flexibility of the inspection, the base 1 is designed with a second movable groove 15 and a side clamping plate 11 to limit the first support 2, the second support 4, and the third support 6. The second movable groove 15 is set in the middle of the base body 12, and a limiting side plate 16 is set on the side, which nests with the first support 2, the second support 4, and the third support 6 for limiting. The side of the base body 12 is provided with a first movable groove 14. The first movable groove 14 cooperates with the movable rod 116 set on the first plate 111 and the second plate 112, so that the first plate 111 and the second plate 112 can rotate. The rotation clamps the plate. Specifically, the rotation clamps the plate by adjusting the handwheel 113. When the handwheel 113 rotates, it presses the top plate 114 of the first plate 111 on top. At this time, the second plate 112 can move, which can quickly position one side. When the handwheel 113 continues to rotate, it can press the second plate 112 through the edge of the limiting hole 115, thereby realizing double-stage limiting.
[0032] The structure of the adjusting handwheel 113 includes a positioning rod 132. The positioning rod 132 is provided with double threads. One side is fixed to the threaded hole of the seat 12, and the other side is engaged with the internal thread of the handwheel 131. When the handwheel 131 rotates, it can drive the second clamping plate 135 to compress the spring 134 and drive the first clamping plate 133 to move. The first clamping plate 133 can be embedded in the limiting hole 115 and fit against the top plate 114 of the first plate 111. During the rotation, it can first lock the first plate 111 in place.
[0033] When the handwheel 131 is rotated and compressed further, the second clamp 135 fits against the outer surface of the second plate 112, thereby achieving secondary positioning. Its main function is to independently control the first support 2 and the third support 6 on both sides, which facilitates rapid adjustment of bearings with large measurement spans.
[0034] The improved device allows for rapid adjustment of the first plate 111 and the second plate 112 via the handwheel 113. This enables the first support 2, the second support 4, and the third support 6 to engage with the locking slot 13 and then achieve dual-stage limiting via the first plate 111 and the second plate 112, thereby improving the overall operational flexibility. The rapid displacement of the first support 2, the second support 4, and the third support 6 allows for the inspection of bearings of more sizes, thus improving the overall inspection efficiency.
[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.
