Problems solved by technology

[0002] At present, automobile inspection fixtures generally use aluminum or steel square tubes to form the basic frame structure of the inspection fixtures, which are heavy, especially for large inspection fixtures, which are cumbersome and very inconvenient to carry. However, the strength of the aluminum square tube is not enough, it is easy to deform under high pressure, and the aluminum parts are sensitive to environmental changes. They are often used at room temperature at the customer's place, and the temperature change will directly affect the size. High, so the use of aluminum is difficult to meet the requirements

Embodiment Construction

[0015] The present invention is described in detail with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following examples.

[0016] Such as figure 1 As shown, a lightweight checking fixture 1 using carbon fiber material as the skeleton of the checking fixture, the skeleton of the checking fixture includes: a polystyrene foam inner layer 2 and a carbon fiber cloth wrapped on the outer periphery of the polystyrene foam inner layer outer layer 3, figure 2 Shown is the cross-sectional schematic diagram of the inspection tool.

[0017] The lightweight inspection fixture can also be formed by stacking layers of carbon fiber cloth.

[0018] Take 40×40mm light-weight inspection fixtures of the present invention and inspection fixtures made of aluminum square pipes and steel square pipes respectively to test the deformation under a certain pressure. During the test, place two support blocks under them respectively. T...

Abstract

The invention discloses a light-weight measuring tool using carbon fiber material as a measuring tool skeleton. The skeleton of the measuring tool is made of a carbon fiber material. The measuring tool not only has light weight, but also has high strength as the strength is high and the coefficient of thermal expansion of carbon fibers is zero. Besides, deformation of the measuring tool along with temperature variation can be avoided.

Description

technical field [0001] The invention relates to the field of automobile inspection fixtures, in particular to a light-weight inspection fixture made of carbon fiber for automobiles, which is mainly used as an opening-type inspection fixture for on-line inspection in the assembly process of automobile OEMs. Background technique [0002] At present, automobile inspection fixtures generally use aluminum or steel square tubes to form the basic frame structure of the inspection fixtures, which are heavy, especially for large inspection fixtures, which are cumbersome and very inconvenient to carry. However, the strength of the aluminum square tube is not enough, it is easy to deform under high pressure, and the aluminum parts are sensitive to environmental changes. They are often used at room temperature at the customer's place, and the temperature change will directly affect the size. High, so the use of aluminum is difficult to meet the requirements.
