Description

Automobile frame inspection platform

technical field

The utility model belongs to a detection device, in particular to an automobile frame detection platform.

Background technique

Due to the large size and complex structure of the existing automobile frame, welding and riveting structures are inevitable at the same time. Therefore, the welding, riveting and preventing deformation of the frame have become the most important and most critical in the manufacturing process of the automobile frame. link, the welding and riveting quality of the larger size frame will directly affect the assembly quality and performance of the whole vehicle, so in addition to taking measures to prevent the deformation of the frame from the process, the size of each point of the frame is tested It is also very important, because the detected data can provide reliable data support for the accurate calibration of the frame and convenient assembly, which is the basis for a reliable guarantee of the quality of the vehicle.

Contents of the invention

The technical problem to be solved by the utility model is to provide an automobile frame detection platform capable of reliably detecting various data of the automobile frame, thereby improving the assembly quality of the whole vehicle.

The technical scheme of the utility model is as follows: the designed automobile frame detection platform, its key points are: comprising a work platform, a reference base and a support frame, wherein the work platform is fixed on the support frame, opposite to each other on the work platform Two sets of "L"-shaped reference bases are provided, the vertical working surfaces of the reference bases on each side are on the same plane, and the vertical working surfaces of the two sets of reference bases are parallel to each other.

The utility model is creatively designed for the existing automobile frame due to its large size, which makes it difficult to detect its various sizes. In the above structure, three jacks are used to support the frame on the working platform and adjust the frame. Parallel to the plane of the working platform, if the height of the jack is not enough due to the shape of the frame, you can use regular auxiliary tools such as V-shaped irons to adjust; the position of the above jacks is symmetrically located on the left and right longitudinal beams at the front end of the frame 1. There is one in the middle of the rear beam of the frame, and the jack can be selected as a standard part in accordance with JB/T 3411.58-1999 "Jack Dimensions". The two sets of "L"-shaped reference seats in the above structure can provide benchmarks and references for the detection of the frame. Use auxiliary tools such as squares, steel rulers or tape measures to adjust the frame to a position parallel to the length of the platform. At the same time, keep a suitable distance between the longitudinal beam of the frame and the working surface of the vertical part of the reference base, so that there is enough space for subsequent measurement. After the frame is adjusted, any point on the frame can be projected onto the plane of the working platform, and the relative coordinate values in the X and Y directions can be determined by using the working surface of the working platform. The distance from this point to the platform is The relative coordinate value in the Z direction. According to this principle, in actual operation, the relevant dimensions of any two points on the frame, as well as the parallelism and warpage of the frame can be measured by using general measuring tools such as a height ruler, a square, a steel ruler or a tape measure. Measured.

In order to make the strength and other performances of the utility model more reliable, and also for the convenience of moving the utility model, the support frame is welded by channel steel arranged vertically and channel steel arranged horizontally, and a hook is welded on the outside of the support frame shaped lugs.

In order to make the utility model easy to place, two sets of supporting pads are arranged at the lower end of the supporting frame.

Equidistant grid lines at a specified distance are engraved on the table surface of the working platform. Setting the grid lines can make detection convenient, so the X and Y points of the point where the vehicle frame is projected onto the working platform can be accurately determined during measurement. The relative coordinate value in the Z direction, and the distance from this point to the platform is the relative coordinate value in the Z direction.

Beneficial effects: the utility model has a simple and novel structure, and can measure various dimensions on the vehicle frame, thereby providing reliable data for the calibration and assembly of the vehicle frame, thereby improving the assembly quality of the vehicle; it has the advantages of convenient processing, convenient use, and easy Realize and other characteristics.
