Description

Technical Field

[0001] The utility model relates to the technical field of automobile door rigidity testing, in particular to a rigidity testing fixing stand for automobile door remanufacturing. Background Art

[0002] Automobile door remanufacturing refers to the professional repair, refurbishment or remanufacturing of old or damaged automobile doors to restore their original performance, appearance and use value. Remanufacturing can not only effectively extend the service life of the doors, but also reduce the environmental pollution caused by improper handling of discarded doors. When remanufacturing automobile doors, it is necessary to conduct rigidity tests on the doors to evaluate their performance. During the test, the doors need to be fixed on a fixed stand to facilitate the testing work.

[0003] A Chinese patent discloses a fixed bench for testing the rigidity of automobile doors (Announcement No. CN220637600U). This patented technology uses a first fixing member and a second fixing member to fix the hinge connection of the door, simulating the actual state of the door during installation. With the help of the load-bearing component and the suspension component, the door is supported, which facilitates the separate fixing of the two sides of the door. At the same time, it can be adjusted for doors of different sizes, making it easier to connect and fix the connecting parts to the hinge connection, and facilitating the testing of the door's rigidity, strength, and dent resistance.

[0004] However, existing automotive door fixing methods often rely on suspension and bolting, resulting in low fixing efficiency and impacting subsequent door rigidity testing. For example, the aforementioned reference document employs a suspension and bolting method. In practice, these methods, when used to fix a door for testing, are inefficient, impacting testing. Therefore, those skilled in the art have provided a rigidity testing fixture for automotive door remanufacturing to address the issues raised in the aforementioned background art.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-4The utility model provides a technical solution for a rigidity test fixed stand for automobile door remanufacturing: comprising: a fixed platform 1 and a positioning groove 11 provided on the upper surface of the fixed platform 1; a movable groove 12 is further provided on the upper surface of the fixed platform 1 on one side of the positioning groove 11; a threaded rod 33 and a guide rod 32 are respectively provided inside the movable groove 12 from left to right; and a movable block 31 is slidably installed outside the threaded rod 33 and the guide rod 32; a movable plate 3 is fixed on the upper surface of the movable block 31; an adjusting mechanism 4 is further provided on the upper surface of the movable plate 3; the adjusting mechanism 4 includes a movable plate 3 fixed on the upper surface of the movable plate 3; and a movable plate 3 is fixed on the upper surface of the movable plate 3. The mounting rod 43 is located in the middle of the upper surface of the plate 3, and a lifting rod 42 is provided through the upper end of the mounting rod 43, and a connecting rod 41 is provided through one end of the lifting rod 42. One end of the connecting rod 41 is connected to the electromagnetic plate 2 above the fixed platform 1. This setting utilizes the operation of the motor 332 to rotate the threaded rod 33, and when rotating, the movable plate 3 moves on the fixed platform 1 to adjust the position of the electromagnetic plate 2, and through the adjustment mechanism 4, when adjusting the height of the electromagnetic plate 2, it can also be pressed against the car door, so that it can be adsorbed and fixed to the car door when powered on, which is convenient for testing.

[0023] like Figure 3 As shown, a first mounting hole 21 is opened in the middle position of one side of the electromagnetic plate 2, and one end of the connecting rod 41 is embedded in the interior of the first mounting hole 21 and is threadedly connected to the first mounting hole 21. This setting utilizes the threaded connection between the connecting rod 41 and the first mounting hole 21 to facilitate the installation and disassembly of the electromagnetic plate 2.

[0024] like Figure 2 and Figure 3 As shown, a second mounting hole 34 is opened in the middle position of the upper surface of the movable plate 3, and the lower end of the mounting rod 43 is embedded in the interior of the second mounting hole 34 and is threadedly connected to the second mounting hole 34. This setting utilizes the threaded connection between the mounting rod 43 and the second mounting hole 34 to realize the installation and disassembly of the mounting rod 43 and the movable plate 3.

[0025] like Figure 4 As shown, a second electric telescopic rod 431 is further provided inside the mounting rod 43, and the telescopic end of the second electric telescopic rod 431 is connected to the lower end of the lifting rod 42. A first electric telescopic rod 421 is also provided inside the lifting rod 42, and the telescopic end of the first electric telescopic rod 421 is connected to one end of the connecting rod 41. This arrangement utilizes the second electric telescopic rod 431 to enable the lifting rod 42 to be raised and lowered to adjust the height of the electromagnetic plate 2. At the same time, the operation of the first electric telescopic rod 421 will cause the connecting rod 41 to move to make the electromagnetic plate 2 close to the car door for subsequent electrified adsorption and fixation.

This setting utilizes the work of the motor 332 to rotate the threaded rod 33, and when rotating, the movable block 31 slides inside the movable groove 12 to adjust the position of the electromagnetic plate 2, which can be easily adapted to different car doors for adsorption and fixation.

[0027] The working principle of the present invention is as follows: when the rigidity test fixing stand for automobile door remanufacturing of the present invention is used, the automobile door that needs rigidity testing is first placed vertically into the inside of the positioning groove 11, and after placement, the motor 332 is started, which causes the threaded rod 33 to rotate, and during rotation, the movable block 31 moves outside the threaded rod 33 and the guide rod 32, thereby driving the movable plate 3 to move to adjust the position of the electromagnetic plate 2, and after adjustment, the second electric telescopic rod 431 inside the mounting rod 43 is started, which causes the lifting rod 42 to rise and fall inside the mounting rod 43, thereby adjusting the height of the electromagnetic plate 2, and at the same time, the first electric telescopic rod 421 can be used to move the connecting rod 41 to make the electromagnetic plate 2 contact with the automobile door, thereby facilitating the subsequent adsorption and fixation of the automobile door to ensure its stability, so as to facilitate the rigidity testing of the automobile door.

[0028] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention.
