Description

Technical Field

[0001] The utility model relates to the technical field of vehicle body opening and closing part detection, in particular to a durability detection device. Background Art

[0002] The car door and car body are connected by opening and closing parts (hinges), so the hinges play a big role in the use of the car. The opening and closing of the car side door generates force on the car hinge, which causes great damage to the hinge during the opening and closing process. After the hinge is produced, it needs to be durable tested to detect whether the hinge meets the standards, so there are many experimental devices on the durability of car hinges.

[0003] The current durability testing devices for opening and closing parts (hinge) all use bolts to fix the hinges on the simulated car body and simulated car door, and then use a cylinder to pull the simulated car door to rotate. However, the hinge sizes of different car models are different, and the installation holes are also different, so the current testing devices are designed for a certain type of hinge detection, and cannot be fixed and installed on different hinges, and the versatility of the detection is poor. In addition, since the telescopic end of the cylinder is rigidly connected to the simulated car door, the cylinder bears part of the weight of the simulated door, which will cause errors in the test results. Therefore, the utility model proposes a durability testing device. Utility Model Content

[0022] The adjustment assembly 4 includes a T-shaped guide rail 41 fixed to the upper surface of the platform 1, a slide seat 42 is slidably connected to the surface of the T-shaped guide rail 41, the fixed plate 3 is fixedly connected to the outer wall of the slide seat 42, and a locking bolt 43 penetrates and is threadedly connected to the top wall of the slide seat 42.

[0023] When installing the opening and closing member 5, the position of the fixing plate 3 can be changed by moving the slide seat 42 so that the two sides of the opening and closing member 5 can just fit with the fixing plate 3 and the simulated door 2. After adjusting the position of the slide seat 42, tighten the locking bolt 43 to fix the slide seat 42.

[0024] A first screw rod 22 penetrates through and is threadedly connected to a side wall of the first L-shaped plate 21 away from the simulated door 2 . The first screw rod 22 abuts against the surface of the opening and closing member 5 .

[0025] The first screw rod 22 is tightened to press against the surface of the opening and closing member 5 to achieve a quick fixed connection between the opening and closing member 5 and the simulated door 2 .

[0026] A second screw 32 penetrates through and is threadedly connected to a side wall of the second L-shaped plate 31 away from the fixing plate 3 . The second screw 32 abuts against the surface of the opening and closing member 5 .

[0027] The second screw rod 32 is tightened to press against the surface of the opening and closing member 5 to achieve a quick fixed connection between the opening and closing member 5 and the fixing plate 3 .

[0028] The traction assembly 6 includes a first vertical plate 61 fixed to the upper surface of the table top 1, and the surface of the first vertical plate 61 is rotatably connected to an electric telescopic rod 62, the telescopic end of the electric telescopic rod 62 is fixedly connected to a pull rope 64, and the other end of the pull rope 64 is fixedly connected to a connecting column 63, the connecting column 63 is hinged to the simulated door 2, and the connecting column 63 is located near the tension spring 8.

[0029] After the electric telescopic rod 62 is shortened, the simulated door 2 can be pulled to rotate through the pull rope 64 and the connecting column 63, thereby driving the opening and closing member 5 to open. When the electric telescopic rod 62 is extended, the tension spring 8 pulls the simulated door 2 to rotate and reset.

[0030] A counter 9 is installed on one side of the second vertical plate 7 close to the simulation door 2. Whenever the simulation door 2 contacts the counter 9, the number of opening and closing is counted once, so that the counter 9 is used to count the number of opening and closing.

During testing, start the electric telescopic rod 62 to reciprocate and extend. When the electric telescopic rod 62 is shortened, the simulated door 2 is pulled to rotate and open through the pull rope 64 and the connecting column 63. When the electric telescopic rod 62 is extended, the tension spring 8 pulls the simulated door 2 to rotate and reset. Every time the simulated door 2 hits the counter 9, the counter 9 counts once, thereby realizing the durability test of the opening and closing member 5. In addition, during testing, the opening and closing angle of the simulated door 2 can be controlled by setting the telescopic stroke of the electric telescopic rod 62, so that the test is more in line with the actual situation.
