[0033] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0034] Please see Figures 1 to 7 The 45-degree universal joint 180-degree rotation life test fixture provided in this utility model embodiment includes: a support plate 1 and an auxiliary device 3. Four test fixture bodies 4 are fixedly connected to the upper surface of the support plate 1 by means of the auxiliary device 3. An adjustment device 2 is provided on the side of the test fixture body 4 near the auxiliary device 3. An auxiliary device 3 is provided on the side of the support plate 1 near the adjustment device 2.

[0035] In the embodiments of this utility model, please refer to Figures 2 to 5The adjusting device 2 includes a connecting frame 201, which is fixedly connected to one side of the auxiliary device 3. The inner wall of the connecting frame 201 is slidably connected to the test fixture body 4. Two connecting plates 202 are fixedly connected to one side of the connecting frame 201.

The two ends of the first spring 205 are fixedly connected to the fixing block 204 and the connecting frame 201, respectively. A contact plate 206 is fixedly connected to the arc surface of the sliding rod 203 away from the fixing block 204. The contact plate 206 is close to the test fixture. An elastic plate 209 is fixedly connected to one side of the main body 4. An abutment block 210 is fixedly connected to the side of the elastic plate 209 away from the contact plate 206. The inner walls of the two sliding rods 203 slide through the same limiting rod 207.

The 45-degree universal joint 180-degree rotation life test fixture main body 4 is a device used to test the durability and performance of universal joints during rotation. The main function of the test fixture main body 4 is to simulate the rotational load and movement that the universal joint is subjected to in actual applications and verify its continuous rotation. The lifespan and stability under rotational conditions are good, but the test fixture body 4 cannot be removed from the support plate 1.

Thus, under the action of slots 214, the stability when limit rod 207 and sliding rod 203 come into contact can be improved. One end of arc surface of limit rod 207 is fixedly connected to guide block 213, which is funnel-shaped.When the limiting rod 207 connects to the inner wall of the sliding rod 203, the guide block 213 installed on the limiting rod 207 can improve the speed of connection between the limiting rod 207 and the inner wall of the sliding rod 203.

The arc surface of the positioning rod 34 near the second spring 35 is... A pressing plate 36 is fixedly connected to one end of the test fixture body 4. When using the test fixture body 4, the working angle of the test fixture body 4 can be adjusted by the auxiliary device 3. Thus, the test fixture body 4 can be rotated and adjusted according to the required working angle by the auxiliary device 3, thereby improving the applicability of the entire test fixture body 4 and improving the use effect. An anti-slip sleeve 37 is fixedly connected to the side of the pressing plate 36 away from the positioning rod 34. When the pressing plate 36 is used to press the positioning rod 34, the anti-slip sleeve 37 installed on the pressing plate 36 can increase the friction of the surface of the pressing plate 36. Thus, under the action of the anti-slip sleeve 37, the stability of pressing the positioning rod 34 by the pressing plate 36 can be improved.

[0037] The working principle of the 45-degree universal joint 180-degree rotation life test fixture provided by this utility model is as follows: Pull the limiting rod 207 in the storage slot 208 to pull the limiting rod 207 out of the storage slot 208. At this time, the sliding rod 203 can be pulled by the fixing block 204. The sliding rod 203 will slide in the connecting plate 202 and the connecting frame 201 and drive the contact plate 206 to move. The movement of the contact plate 206 will drive the elastic plate 209 and the abutment block 210 to move away from the test fixture body 4, aligning the angle of the positioning hole 212 with the angle of the limiting rod 207. At this time, the limiting rod 207 can be connected to the positioning hole 212 through the storage slot 208. At this time, the limiting rod 207 can be connected to the inner wall of the storage slot 208, which can temporarily limit the pulling position of the contact plate 206. At this time, the test fixture body 4 can be taken out from the connecting frame 201.

[0038] Press down on the pressing plate 36. The movement of the pressing plate 36 will cause the positioning rod 34 to slide within the support plate 1. The movement of the positioning rod 34 will cause the second spring 35 to deform. At this time, the positioning rod 34 can slide through the adjustment hole 33. At this time, the turntable 32 can be rotated on the connecting block 31. The movement of the turntable 32 can drive the test fixture body 4 to adjust the angle. After adjusting the test fixture body 4 to the appropriate position, the pressing plate 36 can be released. The second spring 35 will reset and drive the positioning rod 34 to connect with the adjustment hole 33, thus completing the fixation after adjustment.

[0039] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
