[0002] Ceramic bearings are bearings made of ceramic materials and are typically used in mechanical components in harsh environments such as high speed, high temperature, corrosion, and radiation. Due to their superior performance that metal bearings cannot match, they are leading the way in the world of new materials in terms of high temperature resistance and ultra-high strength.

[0003] In the production process of ceramic bearings, vacuum coating is required on the surface of the ceramic bearings. After processing, in order to check the coating quality, several ceramic bearings are randomly selected to test the thickness of the vacuum coating. The existing testing process usually involves workers using an ultrasonic thickness gauge to measure the thickness of the ceramic bearings through the probe. Since the thickness needs to be measured on both the plane and vertical surfaces of the ceramic bearings, deviations can occur when workers adjust the angle of the ceramic bearings, resulting in significant differences in the data measured by the thickness gauge, which reduces the quality of the ceramic bearing testing. Therefore, we need to propose a ceramic bearing vacuum coating thickness testing device. Utility Model Content

During ceramic bearing thickness measurement, a rotating assembly drives a rotating seat to rotate. The rotating seat moves within an arc-shaped groove via a limiting rod.

This solution improves the accuracy of angle adjustment during ceramic bearing detection, avoids deviations during angle adjustment, reduces discrepancies in the thickness gauge data, and improves the quality of ceramic bearing inspection, thus solving the problems mentioned in the background art.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: a ceramic bearing vacuum coating thickness detection device, including a detection platform 1 for detecting ceramic bearings and an ultrasonic thickness gauge 2 for detecting the coating thickness of ceramic bearings. A detection frame 3 is bolted to the top of the detection platform 1. A moving lifting mechanism 4 for changing the detection height and position is installed at the top of the detection frame 3. The bottom end of the moving lifting mechanism 4 is connected to the detection probe 5 of the ultrasonic thickness gauge 2. A rotating component 6 for driving the ceramic bearing to rotate is installed at the bottom of the detection platform 1. A rotating seat 7 is connected to the surface of the rotating component 6. A clamping mechanism 8 for clamping the ceramic bearing is provided on one side of the rotating seat 7. A limit rod 9 is integrally formed on the other side of the rotating seat 7. An arc groove 10 adapted to the limit rod 9 is opened on the inner side wall of the detection frame 3. The angle of the arc groove 10 is set at 90°.

[0023] When inspecting ceramic bearings, the ceramic bearing is first placed on the clamping mechanism 8 and fixed. By default, the angle of the rotating seat 7 is 0°. After fixing the ceramic bearing, it is positioned vertically. Then, the ultrasonic thickness gauge 2 is turned on, and the moving lifting mechanism 4 is activated to adjust the position of the detection probe 5. The moving lifting mechanism 4 moves the detection probe 5 downward to contact the vertical surface of the ceramic bearing, thus detecting the vertical surface of the ceramic bearing. Then, the ceramic bearing rises, and the rotating component 6 is activated to rotate the rotating seat 7 to 90°, changing the ceramic bearing to a flat surface. The moving lifting mechanism 4 then moves the detection probe 5 to contact the ceramic bearing again for detection, thus detecting the flat surface of the ceramic bearing. After the detection is completed, the rotating component 6 drives the rotating seat 7 to reset. This method improves the accuracy of angle adjustment during ceramic bearing inspection, avoids deviations during angle adjustment, reduces the difference in the data detected by the thickness gauge, and improves the inspection quality of ceramic bearings.

[0024] The ultrasonic thickness gauge 2 mentioned in this utility model is a mature existing technology in the field of thickness measurement. This utility model does not impose any further protection or limitations on the ultrasonic thickness gauge 2, and similar products with the same functions can be purchased on the market for use.

[0025] The movable lifting mechanism 4 includes a first push rod 41, which is bolted to the top of the testing frame 3. The push rod part of the first push rod 41 passes through the testing frame 3 and is bolted to a movable seat 42, which is located in the inner cavity of the testing frame 3. The top of the movable seat 42 is provided with a lifting assembly for adjusting the testing height. The bottom end of the lifting assembly passes through the movable seat 42 and is connected to the testing probe 5. The first push rod 41 is connected to a control button via a power cord and is connected to a power supply device via a power cord. Activating the first push rod 41 moves the movable seat 42, adjusting the position of the movable seat 42 within the testing frame 3 to adjust the position of the testing probe 5. Then, the lifting assembly is activated to move the testing probe 5 to contact the surface of the ceramic bearing for testing.

[0026] The lifting assembly includes a second push rod 43, which is bolted to the top of the movable seat 42. The push rod portion of the second push rod 43 passes through the movable seat 42 and is bolted to a lifting seat 44. A mounting seat 45 is provided at the bottom of the lifting seat 44. The lower surface of the mounting seat 45 is bolted to the detection probe 5. Activating the second push rod 43 pushes the lifting seat 44 to move, causing the lifting seat 44 to move the mounting seat 45, which in turn moves the detection probe 5 on the mounting seat 45 toward the surface of the ceramic bearing. By setting up the lifting seat 44, the detection height of the detection probe 5 can be adjusted, facilitating the detection of ceramic bearings of different sizes.

[0027] The first push rod 41 and the second push rod 43 mentioned in this utility model are both connected to the power supply equipment via power cords, and control buttons are also connected via power cords.

[0028] The first push rod 41 and the second push rod 43 mentioned in this utility model are both electric push rods. This utility model does not provide any further protection or limitation for the first push rod 41 and the second push rod 43. Products with the same function can be purchased on the market for use.

[0029] Movable rods 11 are integrally formed around the top of the mounting base 45. Movable holes adapted to the movable rods 11 are opened on the surface of the lifting base 44. The top of the movable rod 11 passes through the movable hole and is bolted to a fixing block. The lifting base 44 drives the mounting base 45 to move downward. The mounting base 45 drives the detection probe 5 to contact the surface of the ceramic bearing. The force generated when the detection probe 5 contacts the ceramic bearing is transmitted to the movable rod 11. Through the cooperation of the movable rod 11 and the movable hole, the mounting base 45 is forced to move upward, which buffers the force generated during contact and avoids damage to the coating on the surface of the ceramic bearing when the detection probe 5 contacts it.

[0030] Both sides of the movable seat 42 are provided with through holes. A support rod 12 is slidably inserted into the inner cavity of the through hole of the movable seat 42. Both ends of the support rod 12 are fixedly connected to the inner side wall of the detection frame 3. The support rod 12 supports both sides of the movable seat 42, preventing the movable seat 42 from shifting its angle when moving in the detection frame 3, and improving the stability of the movable seat 42 when moving in the detection frame 3.

[0031] The rotating assembly 6 includes a first motor 61 mounted on the outer wall of the testing frame 3. The output shaft of the first motor 61 is keyed to a rotating rod 62, and the rotating rod 62 is rotatably connected to the surface of the testing frame 3 via a bearing. The other end of the rotating rod 62 passes through the testing frame 3 and is bolted to the inner wall of the rotating seat 7. The first motor 61 is connected to a power supply via a power cord, and the first motor 61 is also connected to a forward / reverse control button via a power cord. Starting the first motor 61 drives the rotating rod 62 to rotate, and the rotating rod 62 drives the rotating seat 7 to rotate, which in turn drives the ceramic bearing on the clamping mechanism 8 to rotate, thereby adjusting the angle of the ceramic bearing.

[0032] The clamping mechanism 8 includes a fixed frame 81, which is bolted to the center of the rotating seat 7. Both sides of the fixed frame 81 are provided with fixed plates 82 for fixing the ceramic bearing. The surface of the fixed plate 82 is integrally formed with a threaded sleeve. The inner cavity of the fixed frame 81 is provided with a moving component for moving the fixed plate 82. The moving rod component is activated to move the fixed plates 82 on both sides inward, so that the fixed plates 82 on both sides cooperate to clamp and fix the ceramic bearing, thereby improving the stability of the ceramic bearing during testing.

[0033] This embodiment also includes a buffer rubber pad bonded to the inner wall of the fixing plate 82. By setting the buffer rubber pad, the contact force between the fixing plate 82 and the surface of the ceramic bearing is avoided to prevent excessive force from causing scratches to the coating on the surface of the ceramic bearing.

[0034] The moving component includes a second motor 83, which is fixedly connected to the outer wall of the mounting bracket 81 via a mounting plate. The output shaft of the second motor 83 is keyed to a bidirectional threaded rod 84, the other end of which passes through the mounting bracket 81 and is rotatably connected to the inner cavity of the mounting bracket 81 via a bearing. Both sides of the bidirectional threaded rod 84 are threadedly connected to the inner cavity of the threaded sleeve. When the second motor 83 is started, its output shaft drives the bidirectional threaded rod 84 to rotate clockwise. Through the engagement of the bidirectional threaded rod 84 with the threaded sleeve, the mounting plates 82 on both sides move inward to clamp and fix the ceramic bearings. When the second motor 83 drives the bidirectional threaded rod to rotate counterclockwise, the ceramic bearings are released. The second motor 83 is connected to a power supply device via a power cord, and a forward / reverse control button is connected to the second motor 83 via the power cord.

[0035] The first motor 61 and the second motor 83 mentioned in this embodiment are both electric motors. This utility model does not provide any further protection or limitation for the first motor 61 and the second motor 83. Both products can be purchased on the market and used with the same function.

[0036] In practical use: First, place the ceramic bearing between the two sets of fixing plates 82. Start the second motor 83 to drive the bidirectional threaded rod 84 to rotate clockwise, so that the fixing plates 82 clamp and fix the ceramic bearing. Then, start the first push rod 41 to move the moving seat 42, so that the moving seat 42 moves the detection probe 5 directly above the ceramic bearing. Then, turn on the ultrasonic thickness gauge 2. Next, start the second push rod 43 to push the lifting seat 44 downward, so that the mounting seat 45 moves the detection probe 5 to the vertical surface of the ceramic bearing for detection. After the detection is completed, the lifting seat 44 moves the detection probe 5 upward, and start the first motor 61 to drive the rotating rod 62 to rotate. The rotating rod 62 drives the rotating seat 7 to rotate. Through the cooperation of the rotating rod 62 and the arc groove 10, the rotating seat 7 can be quickly adjusted by 90° to achieve planar adjustment. Then, the lifting seat 44 descends, causing the detection probe 5 to contact the surface of the ceramic bearing, thereby detecting the thickness of the coating on the ceramic bearing. The data during the detection is displayed on the screen of the ultrasonic thickness gauge 2. After the detection is completed, the rotating rod 62 rotates back, causing the angle of the rotating seat 7 to reset. The above scheme improves the accuracy of angle adjustment during ceramic bearing detection, avoids deviations during angle adjustment, reduces the difference in the data detected by the thickness gauge, and improves the detection quality of ceramic bearings.

[0037] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
