Description

Technical Field

[0001] This utility model relates to a cylinder parallelism and perpendicularity detection device, and more particularly to a cylinder parallelism and perpendicularity detection device. Background Technology

[0002] The perpendicularity of a bearing directly affects its assembly accuracy with other parts. If the perpendicularity is not up to standard, it may cause deviations in the bearing during assembly, thereby affecting the stability and performance of the entire mechanical system. Bearings with good perpendicularity can ensure that they maintain a stable posture during rotation, reduce vibration and noise caused by deviations, and thus improve rotational accuracy.

[0003] Existing testing devices are difficult to effectively limit the movement of parts such as self-aligning roller bearings when performing parallelism testing, which causes the parts to wobble during the test and affects the accuracy of the test data. Utility Model Content

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.

[0026] 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.

[0027] Existing testing devices struggle to effectively limit movement when inspecting the parallelism of components such as self-aligning roller bearings, leading to component wobbling during testing and affecting the accuracy of the data. Therefore, to address these issues, this paper proposes the following technical solution:

[0028] Reference Figures 1-4 As shown, a cylindrical parallelism and perpendicularity testing device includes: a first base 1, a column 4 is provided on the top of the first base 1, a clamping block 5 and a crossbar 6 are installed on the surface of the column 4, the column 4 and the crossbar 6 are fixed to form a bracket by the clamping block 5, a test gauge 7 is installed on one side of the crossbar 6, the test gauge 7 is perpendicular to the first base 1, a first limiting groove 2 is opened on the surface of the first base 1, a limiting block 3 is nested inside the first limiting groove 2, the limiting block 3 is positioned opposite to the test gauge 7, the limiting block 3 includes a second base 31, a detachable middle seat 33 and a locking block 35 are provided on the top of the limiting block 3, a locking head 353 is opened on one side of the second block 351 of the locking block 35, and a return groove 354 is provided at the bottom of the locking head 353.

[0029] In this embodiment, the main structure of the device includes a first base 1, a first limiting groove 2 is provided on the surface of the first base 1 for fixing the limiting block 3, the limiting block 3 vertically fixes the column 4, the column 4 is used to support the clamping block 5 and the crossbar 6, the height of the clamping block 5 and the crossbar 6 can be adjusted by the column 4, so that the detection gauge 7 can be in a suitable adjustment range.

[0030] A limiting block 3 is set at the bottom of the probe of the test table 7. The limiting block 3 is used to support the bearing. The structure of the limiting block 3 includes a second base 31. The first block 311 of the second base 31 is provided with a central groove 312 for installing the central seat 33. The two sides of the central groove 312 are provided with protruding limiting side blocks 313. The limiting side blocks 313 cooperate with the clamping piece 32 to clamp the side wings 34 on both sides of the central seat 33. The side wings 34 can be disassembled through the clamping piece 32. When measuring bearings of different diameters, quick adjustment can be made to ensure the stability of the bearing when it is in contact.

[0031] A locking block 35 is provided on the top of the middle seat 33. The locking block 35 is used to limit the edge of the bearing. When the bearing is against the locking head 353 on the side of the second block 351, the perpendicularity of the bearing can be detected according to the fit. The fit is achieved by the detection gauge 7 on the top. When rotating, the parallelism of the upper and lower surfaces of the bearing can be detected.

[0032] Furthermore, in order to enable the bearing to fit more closely, a return groove 354 is provided at the bottom of the clamp 353. When the bearing is pushed against it, the space at the bottom allows it to press inward, thus making the fit more closely.

[0033] Given the inconsistent widths of the bearings, an auxiliary chuck 355 is provided on one side of the second block 351, opposite to the chuck 353, to facilitate inspection. The auxiliary chuck 355 has different heights to inspect bearings with larger widths. To ensure greater stability during switching, the second block 351 is fixed by a limiting screw 352, and limiting side plates 356 are installed on both sides of the second block 351. The limiting side plates 356 engage with the two side surfaces of the middle seat 33 to prevent the second block 351 from rotating under external force, thus avoiding data interference during inspection.

[0034] The improved device enables rapid replacement of the base during the testing of bearings of different widths by cooperating with the second base 31 and the middle base 33. A locking block 35 is set on the top of the middle base 33 to engage with the bearing. Through the cooperation of the locking head 353 and the return groove 354, the bearing can fit more closely to the upper surface of the middle base 33 when it is engaged, making the test values ​​more stable. An auxiliary locking head 355 is set on the opposite side of the locking head 353. The auxiliary locking head 355 has different thicknesses and can be quickly switched during testing to improve testing 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.
