Description

Technical Field

[0001] This utility model relates to the field of vehicle assembly auxiliary equipment technology, specifically to a structure that facilitates the adjustment of vehicle side doors during assembly. Background Technology

[0002] The installation of side doors is a challenge in assembling large vehicles. Most side doors are currently sliding doors. In the past, the installation position of sliding doors and their corresponding connecting components needed to be adjusted according to the actual safety requirements. However, in the past, embedded plates were welded onto the frame to fix the positioning shaft of the corresponding sliding door. This installation method obviously makes it difficult to adjust the position of the sliding door, which makes the installation of the sliding door quite difficult. This is the main problem that needs to be solved. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a structure that facilitates the adjustment of the vehicle side hatch during assembly, so as to solve the problem that it is difficult to adjust the position of the sliding side hatch of the vehicle frame according to the actual situation and the installation is difficult.

[0004] To solve the above problems, this utility model provides the following technical solution:

[0005] A structure for facilitating adjustment of a vehicle side hatch during assembly includes a pair of positioning plates connected to a frame; support seats detachably mounted on opposite end faces of the two positioning plates; a support shaft positioned between the two support seats; a curved arm movably mounted on the support shaft; one support rod of the curved arm mounted on the support shaft, and the other support rod being a telescopic rod with a connecting seat at its end; the connecting seat detachably mounted on the side hatch; an ear plate also provided on the curved arm; a cylinder hinged to the ear plate; and the other end of the cylinder rotatably connected to the frame.

[0006] Preferably, the support base is a flat plate structure with a circular hole in the middle; a bearing is installed in the circular hole; the support shaft is a rotating shaft with its end inserted into and installed in the bearing; and several strip holes are opened on the support base at a position outside the positioning hole.

[0007] Furthermore, the support shaft includes a shaft body; set screws are detachably mounted on both ends of the shaft body by means of nuts and spring washers; the protruding ends of the set screws are mounted on the support base.

[0008] Preferably, a clamping plate is provided on the end of the support rod connected to the support shaft on the bent arm; there are two clamping plates, which are detachably clamped to the support shaft by screws; the clamping plates can be adjusted in their installation position relative to the support shaft along the length direction of the support shaft.

[0009] Preferably, the connector is an L-shaped structure with positioning holes.

[0010] Preferably, the mounting height of the positioning plate and the cylinder on the frame is the same; the other end of the cylinder is hinged to the ear plate position on the frame.

[0011] The beneficial effects of this utility model are reflected in the following aspects:

[0012] 1. By using the support base as a standard component, it is easy to disassemble and assemble it from the positioning plate of the frame. It can also be connected to other components first, and then the assembled whole component can be installed onto the frame. This reduces the installation difficulty of structures such as pillars and booms.

[0013] 2. By allowing the curved arm to move left and right on the support column, and by setting the end of the curved arm as a telescopic structure, the position of the curved arm relative to the side hatch can be adjusted more conveniently according to the actual environmental conditions when installing the side hatch through the connecting seat; the flexible positioning and installation of the side hatch in the vertical and longitudinal directions significantly improves the installation adaptability.

[0014] 3. When installed inside the frame, the adjustment mechanisms are all located in the visible and accessible area of ​​the frame, allowing the operator to observe and adjust according to the actual position parameters, thereby improving the positioning accuracy of the equipment.
