Description

Technical Field

[0001] The utility model relates to the technical field of hinge testing, in particular to a vehicle door hinge quality inspection device. Background Art

[0002] With the development of the times, cars have gradually developed into a means of transportation. Now almost every household owns a car. In the process of using the car, the side door of the car is used most frequently. The side door of the car is connected to the car body by a hinge, so the hinge plays a big role in the use of the car. The opening and closing of the side door of the car generates a force on the hinge of the car, which causes great damage to the hinge during the opening and closing process. In order to find a longer service life and more in line with the needs of modern cars, many experimental devices for the quality inspection of automobile hinges have emerged.

[0003] Most of the existing hinge quality inspection equipment fixes the car door and hinge on the test equipment. This method is cumbersome for the installation of the hinge. Due to the weight of the car door itself, the installation and replacement time is long, resulting in low test efficiency. Moreover, during the test, when the hinge is damaged, the car door will fall off at will, causing damage to the car door and increasing the test cost. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the installation of the hinge is relatively complicated, resulting in a long installation and replacement time, and during the test process, when the hinge is damaged, the vehicle door is easily damaged, resulting in an increase in the test cost.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: a vehicle door hinge quality inspection device, including a test bench, a mounting plate fixedly connected to one side of the test bench, a first slide groove is provided in the middle of the test bench, a first slider is slidably connected to the middle of the first slide groove, the top of the first slider is fixedly connected to a base, the top of the base is slidably connected to a test box, and hinge fixing structures are installed on the mounting plate and the test box.

[0006] The utility model is further configured such that the hinge fixing structure includes a slide plate, the slide plate is a T-shaped structure, first slide rails are fixedly connected to both sides of the middle of the slide plate, a plurality of first fixing holes are arranged on the top of the slide plate, and a second hinge fixing plate is fixedly connected to one side of the slide plate.

[0007] The utility model is further configured that a second slide groove is provided at the top of the mounting plate, the second slide groove is slidably connected to the first slide rail, the top of the mounting plate provided with the second slide groove is fixedly connected with a plurality of first bolt fixing structures, and the plurality of first bolt fixing structures are slidably connected to the first fixing hole.

[0008] The utility model is further configured as follows: the hinge fixing structure includes a first hinge fixing plate, the first hinge fixing plate is a U-shaped structure, a third slide groove is provided in the middle inner side of the first hinge fixing plate, a second slide rail is provided on one side of the test box, the second slide rail is slidably connected to the third slide groove, the top end of the second slide rail provided on the test box is fixedly connected with a second bolt fixing structure, and the middle part of the second bolt fixing structure is slidably connected with the second fixing hole.

[0009] Through the above technical solution, the slide plate and the first hinge fixing plate can be disassembled from the mounting plate and the test box, so that before the test, the tester first installs the two ends of the hinge on the slide plate and the first hinge fixing plate respectively, and then engages the slide plate and the first hinge fixing plate with the mounting plate and the test box through the slide rail and the slide groove. Next, the slide plate and the first hinge fixing plate are firmly fixed by the bolt structure. Therefore, the installation is convenient and the test efficiency is greatly improved.

[0010] The utility model is further configured as follows: a sliding cavity is provided in the middle of the test box, a fixed sleeve is slidably connected to the inner side of the sliding cavity, a first reel is rotatably connected to the inner side of the fixed sleeve, a hydraulic telescopic column is fixedly connected to one side of the fixed sleeve, the telescopic end of the hydraulic telescopic column is fixedly connected to the fixed sleeve, a belt is rotatably connected to the middle part of the first reel, a guide reel is slidably connected to the middle part of the belt, the guide reel is rotatably connected to the test box, a second reel is rotatably connected to the bottom end of the belt, and the second reel is rotatably connected to the base.

[0011] Through the above technical solution, the hydraulic telescopic column pushes the fixed sleeve to move horizontally inside the sliding cavity. When the first reel moves, the belt length changes, thereby pulling the second reel closer to the first reel. Because the second reel is fixed on the base, the test box sinks, and the levels of the first hinge fixing plate and the second hinge fixing plate change to simulate the weight of the car door. At the same time, the movement of the first reel can also simulate the center of gravity of the car door, which greatly improves the authenticity of the experiment and ensures the test accuracy of the test equipment.

[0012] The utility model is further configured such that a second sliding column is fixedly connected to the bottom end of the test box, the bottom end of the second sliding column is slidably connected to the base, the top end of the base is fixedly connected to the first sliding column, the top end of the first sliding column is slidably connected to the test box, and springs are provided in the middle of the first sliding column and the second sliding column.

[0013] Through the above technical solution, through the two opposite first sliding columns and the second sliding columns, not only the stability of the connection end between the test box and the base is guaranteed, but also the moving direction of the test box is guaranteed. At the same time, the addition of the spring makes the test box more natural when simulating the weight of the car door, and can simulate the slight vibration and bumps of the car door in actual use, further improving the authenticity and accuracy of the test.

[0014] The utility model is further configured as follows: a third connecting plate is fixedly connected to one side of the first slider, a second connecting plate is fixedly connected to the bottom end of the third connecting plate away from the first slider, the middle part of the third connecting plate is rotatably connected to the test bench, the second connecting plate is rotatably connected to the first connecting plate at one end away from the third connecting plate, the first connecting plate is rotatably connected to a rotating plate at one end away from the second connecting plate, a motor is arranged in the middle part of the rotating plate, the motor is fixedly connected to the test bench, and the power output end of the motor is fixedly connected to the rotating plate.

[0015] Through the above technical solution, the rotating plate is driven by a motor, and the rotating plate passes through the first connecting plate and the second connecting plate while rotating. Since the second connecting plate and the third connecting plate are fixedly connected at the rotating point, the third connecting plate drives the first slider to slide in the first sliding groove. As a result, the first slider drives the base and the test box to rotate 90 degrees, thereby simulating the switching action of the car door in actual use, and ensuring the accuracy of the experimental structure.

[0016] The beneficial effects of the utility model are as follows:

[0017] The utility model uses a hydraulic telescopic column to push the fixing sleeve to move horizontally inside the sliding cavity. When the first reel moves, the length of the belt changes, thereby pulling the second reel closer to the first reel. In addition, because of the two opposite first sliding columns and the second sliding columns, not only the stability of the connection end between the test box and the base is guaranteed, the test box sinks, and the first hinge fixing plate and the second hinge fixing plate change horizontally to simulate the weight of the car door, but also the moving direction of the test box is guaranteed. At the same time, the addition of the spring makes the test box more natural when simulating the weight of the car door, and can simulate the slight vibration and bump of the car door in actual use, which greatly improves the authenticity of the experiment and ensures the test accuracy of the test equipment.
