Description

Technical Field

[0001] The invention relates to the technical field of automobile manufacturing, and in particular to a labor-saving mechanism for a main assembly inspection fixture of a body-in-white. Background Art

[0002] The body-in-white master assembly inspection fixture is a key inspection tool for controlling the body size quality during the automobile production process. Almost every new model will develop a separate master assembly inspection fixture. Since the body-in-white master assembly inspection fixture is large in size and frequently used, it is particularly important to develop a master assembly inspection fixture that is easy to operate and saves time and effort.

[0003] The main assembly fixture of the body in white is mainly composed of the lower body mounting bracket and the left and right side panel fixtures. Under normal circumstances, the body side panel parts need to be matched with the side panel fixtures opened, and after the loading is completed, the side panel fixtures are pushed to complete the assembly with the lower body. In the process of analyzing the body size problem, the side panel fixtures need to be opened and closed frequently. At present, the opening and closing operations of the side panel fixtures of most white body main assembly on the track are completely pushed and pulled by manpower, requiring at least 3 people to operate simultaneously to complete the side panel movement and latch action, which is complicated and time-consuming and labor-intensive.

[0004] In summary, the main assembly inspection tool of the body in white is large in size, and the side panel inspection tool is frequently opened and closed, which is time-consuming, labor-intensive and difficult to operate. At present, most of the main assembly inspection tools do not have a labor-saving mechanism for moving the side panel, resulting in excessive consumption of human resources. It is urgent to design a labor-saving mechanism to solve the problem of the difficulty in moving the side panel inspection tool. Summary of the invention

[0005] In view of the defects in the prior art, the purpose of the present invention is to provide a labor-saving mechanism for the main assembly inspection fixture of the body-in-white. A hand-cranked screw mechanism is innovatively designed at the bottom of the main assembly side panel. The rotation of the screw is converted into the translational movement of the side panel inspection fixture along the track by rotating the turntable, thereby realizing the assembly and withdrawal operations of the inspection fixture. The turntable and the insertion of the locating pin can be operated by a single person throughout the whole process. This mechanism has the advantages of easy operation, labor saving, simple structure and low additional cost.

[0006] In order to achieve the above-mentioned invention object, the present invention provides a body-in-white main assembly inspection tool labor-saving mechanism, including a rotating wheel, a screw rod, a screw rod box, a bearing, a connecting plate and a base;

[0007] The base is connected to the floor and fixed, the screw box is arranged on the base, the screw extends from the screw box and the end of the screw away from the screw box is connected to the rotating wheel, the connecting plate is arranged on the screw through the bearing, and the connecting plate is used to be connected to the side enclosure inspection fixture.

[0008] Preferably, the lower end of the connecting plate is connected to the screw rod through a bearing, and the upper end is used to connect to the side panel inspection fixture.

[0009] Preferably, the rotating wheel comprises a rotating disk and a handle, and the handle is arranged in a circumferential direction close to the rotating disk.

[0010] Preferably, one rotation of the turntable corresponds to a preset movement distance of the side panel inspection fixture.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The present invention designs and installs a hand-cranked screw device on the side panel inspection fixture, and realizes the translation of the side panel inspection fixture on the track by rotating the rotating wheel, thereby realizing the opening and closing movement of the side panel inspection fixture. Compared with the traditional mechanism that relies on manpower to push, this mechanism has a simple structure and is easy to operate. One circle of rotation of the rotating wheel corresponds to a fixed movement distance of the side panel. A single person with skillful operation can complete the opening and closing and latching actions of the side panel inspection fixture. BRIEF DESCRIPTION OF THE DRAWINGS
