Description

Clamp device capable of accurately measuring thickness of metal plate adhesive

Technical Field

The utility model relates to a fixture tool for an automobile, in particular to a fixture device capable of accurately measuring the thickness of an inter-metal plate adhesive.

Background

In order to achieve the aim of light weight of automobiles, the use of light materials such as aluminum magnesium alloy and the like becomes a mainstream trend, and the hybrid automobile body structure is the important direction of research of various automobile enterprises at present.

Most of mixed car body parts can relate to the connection problem of dissimilar metal materials, gluing is also a common metal connection process, connection is even, stress distribution is good, in addition, galvanic corrosion phenomenon can occur due to the difference of properties of the dissimilar metal, structural adhesive is added between metals to play a role in isolation and sealing, meanwhile, the structural adhesive can play a role in buffering and absorbing energy in a car body collision process, different gluing thicknesses can have a certain influence on the connection strength of the dissimilar metal and subsequent welding and riveting, and therefore, the influence of the gluing thickness on the connection performance and the determination of the optimal gluing thickness are important points of the test.

At present, the gluing test process adopts manual gluing and the existing simple clamp clamping method, so that the gluing thickness is difficult to accurately determine, the stability is poor and deviation exists. The method is commonly adopted, wherein glass beads with the required glue thickness are mixed in the structural glue, the glass beads are clamped by a simple clamp after being manually glued, and a sample with the required glue thickness is obtained after high-temperature solidification. However, the thickness of the glue to be controlled in the test is between 0.2mm and 1.5mm, and the situation that the glass beads are small in diameter and large in structural adhesive strength can cause uneven distribution of the beads, so that the analysis of the test results can be influenced by the inability of accurately controlling the thickness of the glue. Therefore, the real glue thickness value is obtained preferably by a physical measurement method before high-temperature curing, but the reserved measurement space is smaller when the conventional clamp clamps, so that the adhesive sample in the clamped state is difficult to be measured by high-precision measuring tools such as a micrometer, and the glue thickness can be changed when the adhesive sample is measured firstly and then clamped. To sum up, design an adhesive clamp device for guarantee that the sample is firm to be held, steadily place in high temperature curing equipment, can accurately measure the thickness of gluing in the centre gripping in order to satisfy the requirement of experimental precision simultaneously.
