Description

A universal joint testing device Technical Field

[0001] This utility model relates to the field of universal joint testing technology, specifically a universal joint testing device. Background Technology

[0002] In many fields such as automobile manufacturing and mechanical engineering, universal joints are key components in transmission systems, and their performance and quality directly affect the stability and reliability of the entire transmission system. Therefore, accurate testing of universal joints is crucial.

[0003] Currently, universal joint testing mainly relies on manual operation or traditional testing equipment. On the one hand, traditional testing equipment has a relatively simple clamping and fixing method for universal joints, lacking flexibility and adaptability. Different specifications and sizes of universal joints require different clamping devices, and traditional equipment often struggles to quickly adjust to meet diverse clamping needs, leading to unstable universal joint fixing during testing and affecting the accuracy of the test results. On the other hand, traditional testing equipment has limitations in adjusting the spatial position of universal joints. When testing universal joints, multi-angle and multi-directional testing is required, but traditional equipment cannot achieve flexible movement and rotation of the universal joint within a spatial range, limiting the testing scope and preventing comprehensive and in-depth testing of various performance indicators of the universal joint. Therefore, we propose a universal joint testing device. Summary of the Invention

[0004] The purpose of this invention is to provide a universal joint testing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A universal joint testing device includes a base plate. A mounting frame is disposed on the top left side of the base plate, and a transverse moving frame is slidably disposed on the top right side of the base plate. A vertical moving frame is disposed at the moving end of the transverse moving frame, and a moving block is disposed at the moving end of the vertical moving frame. Clamping mechanisms are disposed on the side walls of the mounting frame and the moving block. The transverse moving frame is slidably connected to the base plate via a slider. The clamping mechanism includes a turntable rotatably disposed on the right side wall of the mounting frame and a turntable fixedly connected to the left side wall of the moving block. A plurality of mounting plates are evenly disposed on the inner wall of the turntable. Telescopic cylinders are disposed on the mounting plates. Clamping seats are disposed at the ends of the telescopic arms of the telescopic cylinders. The left turntable is rotatably connected to the mounting frame. An external gear ring is disposed on the outer wall of the left turntable. A gear is also disposed on the mounting frame via a drive motor, and the gear meshes with the external gear ring.

[0007] As a further embodiment of this utility model: a threaded rod is rotatably provided inside the base plate, the threaded rod passing through the slider and being threadedly connected to the slider.

[0008] As a further improvement of this utility model: the mounting plate is also provided with a through hole, and a slide rod is slidably disposed in the through hole, with the inner end of the slide rod connected to the clamping seat.

[0009] As a further improvement of this utility model, a limit block is provided at the outer end of the slide rod.

[0010] As a further improvement of this utility model, both the horizontal moving frame and the vertical moving frame are controlled to move by a lead screw, a guide rail, and a lead screw motor.

[0011] As a further improvement of this utility model: a servo motor is provided on the outer wall of the left side of the base plate, and the power output shaft of the servo motor is connected to a threaded rod through a coupling.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The equipment is equipped with mounting frames and multi-directionally movable clamping mechanisms on the left and right sides of the top of the base plate. Through the coordinated action of the horizontal moving frame, the vertical moving frame, and the moving block, and with the precise control of the lead screw, guide rail, and lead screw motor, the right clamping mechanism can move flexibly left and right and up and down within the space. It can quickly adapt to the clamping requirements of universal joints of different specifications and sizes. At the same time, both the left and right clamping mechanisms are equipped with turntables. The left turntable meshes with the gear driven by the drive motor through the external gear ring, which can drive the universal joint to rotate. It can adjust the spatial position and angle of the universal joint in all directions, providing a strong guarantee for comprehensive and in-depth testing.

[0014] 2. A servo motor drives the threaded rod, which in turn moves the transverse moving frame, enabling automatic adjustment of the clamping mechanism's position. This reduces manual intervention and improves testing efficiency. In the clamping mechanism, a telescopic cylinder drives the clamping seat to clamp the universal joint. The sliding rod slides in the through hole to ensure the sliding efficiency of the clamping seat. Limit blocks prevent the sliding rod from falling off, ensuring a stable and reliable clamping process. This automated and stable clamping and position adjustment method effectively avoids errors and instabilities caused by manual operation, improving the accuracy and consistency of testing.

[0021] Example

[0022] Please refer to Figures 1-4. In this embodiment of the present invention, a universal joint detection device includes a base plate 1. A mounting frame 2 is provided on the top left side of the base plate 1, and a transverse moving frame 12 is slidably provided on the top right side of the base plate 1. A vertical moving frame 13 is provided at the moving end of the transverse moving frame 12, and a moving block 14 is provided at the moving end of the vertical moving frame 13. Clamping mechanisms are provided on the side walls of the mounting frame 2 and the moving block 14. Under the action of the transverse moving frame 12 and the vertical moving frame 13, the right clamping mechanism can be driven to move left, right, up, and down within the spatial range. The transverse moving frame 12 and the vertical moving frame 13 are both controlled by screws, which is prior art and therefore not described in detail in this application. Those skilled in the art can easily understand its working principle.

[0023] The clamping mechanism includes a turntable 3 rotatably mounted on the right side wall of the mounting frame 2 and a turntable 3 fixedly connected to the left side wall of the movable block 14. Several mounting plates 7 are evenly arranged on the inner wall of the turntable 3. Telescopic cylinders 8 are mounted on the mounting plates 7, and clamping seats 9 are located at the ends of the telescopic arms of the telescopic cylinders 8. When the universal joint needs to be inspected, the operator places the two mounting shafts of the universal joint between the clamping seats 9. The telescopic cylinders 8 then move the clamping seats 9, thereby clamping and fixing the mounting shafts on the left and right sides of the universal joint. This ensures the quality of the device's clamping and fixing of the universal joint, which helps to ensure the efficiency and quality of subsequent testing of the universal joint. The mounting plate 7 also has a through hole, in which a slide rod 10 is slidably installed. The inner end of the slide rod 10 is connected to the clamping seat 9. Under the action of the slide rod 10, the sliding efficiency of the clamping seat 9 is ensured. A limit block 1001 is provided at the outer end of the slide rod 10. Under the action of the limit block 1001, the occurrence of the slide rod 10 falling off is reduced, thereby ensuring the efficiency of the use of the slide rod 10.

[0024] The left turntable 3 is rotatably connected to the mounting bracket 2. An external gear ring 4 is provided on the outer wall of the left turntable 3. A gear 6 is also provided on the mounting bracket 2 through the drive motor 5. The gear 6 meshes with the external gear ring 4. At this time, the drive motor 5 drives the gear 6 to rotate, thereby driving the turntable 3 to rotate through the external gear ring 4, and then driving the universal joint to rotate, which facilitates the subsequent inspection of the universal joint.

[0025] A threaded rod 15 is rotatably installed inside the base plate 1. The transverse moving frame 12 is slidably connected to the base plate 1 via a slider 16. The threaded rod 15 passes through the slider 16 and is threadedly connected to the slider 16. Rotating the threaded rod 15 will drive the transverse moving frame 12 to move, thereby meeting the fixing requirements for universal joints of different lengths. At the same time, when conducting angular rotation tests within the universal joint's spatial range, the transverse moving frame 12 can move left and right, thus ensuring the efficiency of the test. A servo motor 17 is installed on the outer left side of the base plate 1. The power output shaft of the servo motor 17 is connected to the threaded rod 15 via a coupling. The servo motor 17 can drive the threaded rod 15 to rotate. By observing the rotation angle of the universal joint, the operator can perform the test work.

[0026] In actual use, the mounting shafts at both ends of the universal joint are first placed between the left and right clamping seats 9. For the right clamping mechanism, the servo motor 17 is started, which drives the threaded rod 15 to rotate through the coupling. Since the threaded rod 15 is threadedly connected to the slider 16, and the slider 16 is connected to the transverse moving frame 12, the transverse moving frame 12 moves left and right. At the same time, the vertical moving frame 13 drives the moving block 14 to move up and down under the action of the lead screw, so that the right clamping mechanism can be flexibly adjusted in position within the space to adapt to the fixing requirements of universal joints of different lengths. Afterwards, the telescopic cylinder 8 extends and retracts, driving the clamping seat 9 to move and clamp and fix the universal joint mounting shaft. The slide rod 10 slides in the through hole to ensure the sliding efficiency of the clamping seat 9. The limit block 1001 prevents the slide rod 10 from falling off. For the left clamping mechanism, the drive motor 5 starts and drives the gear 6 to rotate. The gear 6 meshes with the external gear ring 4, and the external gear ring 4 drives the turntable 3 to rotate, which in turn drives the universal joint to rotate, facilitating subsequent testing. During the testing process, the transverse moving frame 12 can move left and right. In conjunction with the rotation of the universal joint, it can meet the angle rotation test within the space of the universal joint. The staff observes and records the rotation of the universal joint, thereby completing the testing of the universal joint.
