Description

A Checking Fixture for Automobile Tubular Beams

technical field

The invention relates to a checking tool, in particular to a checking tool for a tubular beam of an automobile, and belongs to the technical field of automobile tooling.

Background technique

With the development of the economy and the improvement of living standards, the use of automobiles is increasing year by year. The relationship between vehicles and human beings is really inseparable, and between vehicle manufacturers, vehicle component manufacturers and drivers, not only the performance, safety and fuel-saving effect of the vehicle itself are pursued, but also the components of the vehicle are becoming more and more important. Pay attention.

The beam is a key component of the car, especially the beam of the dashboard of the car. The beam of the dashboard of the car is an important part to ensure the stable and reliable use of various instruments of the car, including the beam, the metal sheet and the mounting hole. The high-speed rotation of the high-power engine and the harsh road conditions of the vehicle are likely to cause strong vibration and jolts to the cab, resulting in disconnection or failure of the instrument circuit and some functions in the front control panel.

Because the tubular beam has good compression resistance, many cars now use tubular beams, such as the T250 tubular beam, as shown in Figure 1, the T250 beam is in the shape of a "T" shape and is made of metal. , including the main part of the beam, the middle part of the beam and the side part of the beam.

The main part of the beam is a horizontal tubular structure, the middle of the main part of the beam is raised, and the main part of the beam is provided with installation holes.

The middle part of the crossbeam is connected with the vertical ladder-like structure. The middle part of the crossbeam includes two vertical metal frames, and the ends of the metal frames are close to the middle; the two vertical metal frames are connected to the horizontal metal sheet, and the metal sheet is provided with installation holes.

The two sides of the main part of the beam are longitudinal side parts of the beam, the side parts of the beam are connected with the metal sheet, and installation holes are arranged on the side part of the beam and the metal sheet.

Shape correction means that after the workpiece has gone through various stamping processes, because its dimensional accuracy and surface shape cannot meet the requirements of the part, at this time, it is necessary to pass a special mold on the basis that its shape and size are already close to the requirements of the part. It is a stamping processing method that causes little plastic deformation to obtain qualified parts. The purpose of shape correction is to trim the unevenness or arc of the workpiece surface to meet the requirements of the drawing. Generally speaking, for stamping parts with high surface shape and size requirements, shape correction is often required. Shape correction is widely used in machinery manufacturing fields such as automobiles.

Fixtures and checking fixtures are often used in form correction work. The traditional fixture is made of a steel plate or steel pipe welded base and a metal bracket as structural parts. Due to the use of an integral steel plate or steel pipe welded structure, the fixture is very heavy and difficult to move. The traditional shape correction method is to use the inspection tool to inspect the beam. If the pin gauge can pass through the mounting hole on the beam and conforms to the hole diameter, the product is qualified. If the gauge pin cannot pass through the mounting hole on the beam, it needs to be fixed on the On the jig, use the tool, and make corrections. Due to the large size and weight of the tubular beam, it is inconvenient to move. This process needs to go through two processes of inspection tools and fixtures, which takes double the time and is time-consuming and labor-intensive.
