Description

Technical Field

[0001] The utility model belongs to the technical field of roller profile detection, in particular to a multi-size roller profile detection device. Background Art

[0002] Bearing rollers support rotating parts through rolling friction inside the bearing. The performance indicators of bearing rollers cover multiple aspects such as geometric dimensions, surface quality, hardness, precision, and materials. High-quality rollers can provide better load distribution in the bearing, reduce wear, and increase the service life and stability of the bearing. During design and manufacturing, ensuring that these indicators meet the requirements is key to ensuring the efficient operation of the bearing. Therefore, the accuracy of the roller profile determines the performance and service life of the bearing. Roller profile detection is an important step in the bearing production process, used to ensure the accuracy and consistency of the roller surface shape. The shape of the roller directly affects the operating performance of the bearing, including friction, noise, temperature rise, and life. Therefore, the shape quality of the roller must be strictly controlled. Common bearing roller profile detection indicators include roundness, diameter tolerance, cylindricity, eccentricity, external cylindrical runout, aspect ratio, surface roughness, surface defects, inclination, and hardness. Therefore, roller profile detection devices become crucial.

[0003] Among the existing public patents, the Chinese patent application number CN202222872185.8 discloses a device for detecting the roundness of cylindrical bearing rollers, which belongs to the field of bearing detection technology. The device includes a workbench with a circular groove, a rotating device clamped in the workbench, and a sliding connection in the clamping device. The rotating device includes a motor clamped in the workbench, and a first rotating shaft is fixedly connected to the motor. The device for detecting the roundness of cylindrical bearing rollers is provided with a circular groove and a detection device. When the handle is pulled down, four limit plates drive four sliders to slide in four limit grooves until the bearing roller to be detected is limited.

[0004] However, there are some problems with the existing technology: the above-mentioned detection device uses a slider to limit the bearing roller, and manually moves the telescopic rod to make the detection head of the roundness detection device fit with the curved surface of the bearing roller. The bearing roller is driven to rotate by a motor for detection. However, the method of manually pushing the detection head to fit with the curved surface of the bearing roller not only wastes manpower but also cannot accurately control the fitting force between the detection head and the bearing roller. If the force is too large, it is easy to damage the bearing roller surface and the detection head. If the force is too small, there is no fit with the roller curved surface, and the detection is inaccurate. Therefore, we propose a multi-size roller profile detection device. Utility Model Content

[0027] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0028] like Figures 1 to 6 As shown, an embodiment of the present invention provides a multi-size roller profile detection device, including a detection machine body 1, a turntable 2 is rotatably connected to the center of the upper part of the detection machine body 1, a slide rail 6 is provided on one side of the detection machine body 1, the bottom of the slide rail 6 is fixedly connected to the inside of the detection machine body 1, and a detection device 3 is slidably connected to the slide rail 6;

[0029] A driving motor 5 is provided at the bottom of the turntable 2, and the driving motor 5 is fixedly connected to the inside of the detection machine body 1. A fixing rod 214 is provided above the driving motor 5. The top of the fixing rod 214 is fixedly connected to the top of the turntable 2, and the bottom of the fixing rod 214 is fixedly connected to the output shaft of the driving motor 5. The outer side of the fixing rod 214 is slidably connected to the sliding rod 213. The outer side of the sliding rod 213 is evenly connected to four groups of second connecting rods 212 for rotation. An adjusting push plate 210 is correspondingly provided above the second connecting rod 212. The bottom of the adjusting push plate 210 is rotatably connected to one end of the second connecting rod 212, and the bottom of the adjusting push plate 210 is slidably connected to the upper surface of the turntable 2;

[0030] It should be noted that the detection device 3 is equipped with a telescopic detection head, which determines whether the shape of the roller 4 to be tested is qualified by the magnitude of the reaction force fed back when it contacts the curved surface of the rotating roller 4 to be tested. The telescopic detection head moves synchronously with the adjustment push plate 210 and fits the surface of the roller clamped by the adjustment push plate 210.

[0031] Furthermore, the slide rail 6 is L-shaped, the detection device 3 is slidably connected to the horizontal track of the slide rail 6, and the lift plate 8 is slidably connected to the vertical track of the slide rail 6;

[0032] It should be noted that the detection device 3 moves synchronously with the lifting and lowering of the lifting plate 8. When the lifting plate 8 slides upward, the detection device 3 slides away from the lifting plate 8. Through the synchronization of the detection device 3 and the lifting plate 8, the roller 4 to be inspected can be quickly clamped and fixed while the telescopic detection head of the detection device 3 is accurately fitted to the curved surface of the roller 4 to be inspected, which saves manpower and improves detection efficiency.

[0033] Furthermore, the lifting plate 8 is L-shaped, the vertical portion of the lifting plate 8 is slidably connected to the slide rail 6, the horizontal portion of the lifting plate 8 is rotatably connected to the bottom end of the sliding rod 213, and the fixed rod 214 passes through the horizontal portion of the lifting plate 8;

[0034] It should be noted that, while the sliding rod 213 and the horizontal portion of the lifting plate 8 rotate, they can also drive the lifting plate 8 to move up and down, without affecting the rotation of the turntable 2 .

[0035] Furthermore, a locking device 9 is fixedly connected to the side of the vertical portion of the lifting plate 8, and the locking device 9 is slidably arranged with the slide rail 6;

[0036] It should be noted that when the adjusting push plate 210 clamps the roller 4 to be inspected, the adjusting push plate 210 is fixed by the locking device 9, which prevents the adjusting push plate 210 from loosening due to centrifugal force when the turntable 2 rotates, thereby improving the stability of the detection device.

[0037] Furthermore, a first connecting rod 7 is provided between the lifting plate 8 and the detection device 3, and both ends of the first connecting rod 7 are rotatably connected to the detection device 3 and the lifting plate 8 respectively;

[0041] Furthermore, an adjusting bolt 10 is provided inside the locking device 9 , a thread groove is provided inside the locking device 9 , and the adjusting bolt 10 is connected to the inside of the locking device 9 through threads.

[0042] It should be noted that when the adjusting bolt 10 is tightened, the end of the adjusting bolt 10 is fixed by pressing against the slide rail 6 , thereby improving the stability of clamping the roller 4 to be inspected.

[0043] Furthermore, the detection device 3 is aligned with a set of adjustment push plates 210 in the vertical direction, and a handle 211 is fixedly connected to the outer side of the adjustment push plates 210 aligned with the detection device 3;

[0044] It should be noted that during the movement of the adjusting push plate 210, the telescopic detection head on the detection device 3 in the vertical direction always maintains an external tangent to the inner arc surface of the adjusting push plate 210, ensuring that after the roller 4 to be inspected is clamped and fixed, the telescopic detection head of the detection device 3 fits the curved surface of the roller 4 to be inspected.

[0045] Examples of the present application:

[0046] Preparation before testing: Place the roller 4 to be tested in the middle of the adjusting push plate 210 on the turntable 2, push the handle 211 to make the adjusting push plate 210 clamp and fix the roller 4 to be tested, and at the same time, the second connecting rod 212 drives the sliding rod 213 to slide downward, driving the lifting plate 8 to slide downward, and the lifting plate 8 makes the testing device 3 and the adjusting push plate 210 move synchronously through the first connecting rod 7, and the telescopic testing head on the testing device 3 and the inner arc surface of the adjusting push plate 210 always maintain an external tangent state in the vertical direction. After the adjusting push plate 210 clamps the roller 4 to be tested, tighten the adjusting bolt 10 to fix the adjusting push plate 210 to ensure the stability of the clamping.

[0047] Detection process: The detection equipment 3 adjusts the length of the detection head to an appropriate length, fits the curved surface of the roller 4 to be tested, starts the drive motor 5 to drive the turntable 2 to rotate, and the detection head performs detection through the feedback of the reaction force when it contacts the roller 4 to be tested.

[0048] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
