DETAILED DESCRIPTION

[0020] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1

[0022] See also Figure 1-3The present embodiment provides a vehicle bushing durability test device, comprising a machine base 1, a fixed vertical plate 2 is bolted to one side of the top of the machine base 1, two parallel slide grooves 5 are provided on the top of the machine base 1, the inner grooves of the slide grooves 5 are meshed and slidably connected with a slider 4, a movable vertical plate 3 is welded to one side of the top of the slider 4, and the movable vertical plate 3 is moved, so that the bushing and the fixed vertical plate 2 can be conveniently fixed. The fixed vertical plate 2 is relatively to the movable vertical plate 3 and is connected to an electric turntable 6 for rotation in the inner groove near the center of the circle. The outer side of the electric turntable 6 is provided with a slot and a fixing column 7 is provided for sliding near the inner groove. By placing the bushing into the inner groove of the electric turntable 6 and then squeezing and fixing it by the fixing column 7, the device can be conveniently used to perform fixed tests on bushings of different models, thereby improving the applicability of the device and making the device more comprehensive. A testing machine 8 is provided on the side wall of the fixed vertical plate 2 near the outer side of the electric turntable 6, and the testing machine 8 is screwed on one side of the electric turntable 6. The bolt is connected with a test pump rod 9, and the end of the test pump rod 9 away from the test machine 8 is bolted with a test block 10. There are multiple sets of detachable test machines 8, and the test pump rod 9 and the test block 10 perform simultaneous impact durability tests on multiple positions of the bushing. This can effectively simulate the extrusion and impact that the bushing is subjected to from multiple directions during actual automobile driving, restore the actual use environment as much as possible, and perform the durability test more accurately and effectively. The accuracy of the durability test of the bushing is guaranteed to be comprehensive, and the stability and durability of the automobile bushing during use are guaranteed, reducing the risk of accidents. The relative position of the movable vertical plate 3 relative to one side of the electric turntable 6 is rotatably connected with a connecting shaft cylinder 11. After the bushing is fixed to the electric turntable 6, the other end is plugged into the connecting shaft cylinder 11, and then the connecting shaft cylinder 11 is assisted in rotation during rotation, which can effectively improve the stability of the bushing rotation test and the use of the lifting device is stable and efficient.

[0023] After the bushing is produced and formed, it needs to be tested for durability. At this time, one end of the bushing is fixed to the slot of the electric turntable 6, and the fixed column 7 is pushed by the pump body in its inner slot to fix the bushing. Then the motor drives the rotating rod 27 in the rotating slot 26 to rotate, and the rotating rod 27 drives the screw 25 to rotate in the slide slot 5 through the meshing gear 28. The screw 25 is threadedly connected to the slider 4, and the slider 4 is welded to the movable vertical plate 3. Therefore, the sliders 4 on both sides realize the sliding effect in the slide slot 5 through the screw 25, and the slider 4 drives the movable vertical plate 3 to move toward the fixed vertical plate 2. Then the connecting shaft cylinder 11 is inserted into the inner arc groove of the bushing. After the bushing is fixed, the corresponding multiple groups of testing machines 8 are started at this time, and the test pump rod 9 drives the test block 10 to extend and contract to impact the outside of the bushing. The bushing can also be rotated and subjected to durability impact tests through the electric turntable 6 and the connecting shaft cylinder 11.

[0024] In the prior art, the test of the bushing durability test equipment is a unidirectional impact test, so the durability test data is relatively single and cannot meet the durability safety in the subsequent actual use process, which poses certain safety hazards.

[0025] Embodiment 2

[0026] See also Figure 4 , further improvements were made on the basis of Example 1:

[0027] A mounting groove 13 is provided at the relative position of the fixed vertical plate 2 close to the test machine 8, and the mounting groove 13 is meshed and plugged and connected with a mounting block 12, and the mounting block 12 is fixedly connected to one side of the test machine 8. The test machine 8 and the fixed vertical plate 2 are assembled and disassembled by means of the mounting block 12 and the mounting groove 13, so that the device can be more flexibly installed and disassembled when a number of sets of test machines 8 are needed, and the subsequent maintenance and inspection of the test machine 8 are also more convenient and efficient. Slots 18 are provided on opposite sides of the mounting block 12, and the inner groove of the slot 18 is meshed and plugged and connected with a plug plate 17. A fixed groove 14 is provided on the inner side wall of the fixed vertical plate 2 close to the mounting groove 13, and the plug plate 17 penetrates and is slidably connected to the inner groove wall of the fixed groove 14. A moving rod 16 is welded to one side of the plug plate 17 close to the inner groove of the fixed groove 14, and the moving rod 16 penetrates and is threadedly connected with the positive and negative threaded rods 15, and a roller 22 is rotatably provided on the inner groove wall of the fixed vertical plate 2, and a transmission is welded and connected through the center of the roller 22. The shaft 21, the transmission shaft 21 and the inner groove wall of the fixed groove 14 are penetrated and rotatably connected, the positive and negative threaded rod 15 is welded with a transmission rod 19 at one end relative to the transmission shaft 21, and a transmission belt 20 is sleeved on the outer side of the transmission rod 19 and the transmission shaft 21. When the test machine 8 is installed on the fixed vertical plate 2, by rotating the roller 22, the transmission shaft 21 rotates accordingly, and the transmission shaft 21 drives the transmission rod 19 to rotate through the transmission belt 20. The transmission rod 19 is welded and connected with the positive and negative threaded rod 15. At this time, the positive and negative threaded rod 15 and the moving rod 16 are threadedly rotated. The moving rod 16 is limited by the plug plate 17 that engages and slides with the fixed groove 14 at this time. Therefore, the moving rod 16 will not rotate with the positive and negative threaded rod 15, but the plug plate 17 is moved in the direction of the installation groove 13 through the threaded rotation of the positive and negative threaded rod 15 and the moving rod 16. After that, the plug plates 17 on both sides are plugged into the slots 18 on both sides of the mounting block 12 to complete the fixing of the test machine 8, otherwise it can be disassembled.

A rotating rod 27 is provided on the outer wall of the end of the machine base 1 close to the rotating groove 26 through a motor. The rotating rod 27 is rotatably connected to the inner groove wall of the rotating groove 26. The rotating rod 27 is welded to the position of the screw 25 and the opposite end thereof with two mutually meshing gears 28. Through this transmission structure, the movable vertical plate 3 can move more stably and synchronously when fixing or unloading the bushing, reducing the problem of movement dislocation, thereby ensuring the bushing stability and test efficiency of the test.

The positioning groove 24 is arranged at a relative position on one side of the movable vertical plate 3 relative to the positioning plate 23. When the movable vertical plate 3 and the fixed vertical plate 2 are subjected to a fixed durability test on the bushing, the engagement and plugging of the positioning plate 23 and the positioning groove 24 can achieve the accuracy of device fixation and reduce the problem of fixed misalignment. In addition, the engagement and plugging of the positioning plate 23 and the positioning groove 24 can also achieve a certain fixing and stabilizing effect on the testing machine 8, thereby ensuring the stability and efficiency of the test components during the durability test, improving the efficiency of the test, and ensuring the stability and accuracy of the detection data.
