Embodiment Construction

[0010] Such as figure 1 as shown,

[0011] The combined measuring tool for body gap and surface difference is made of a piece of GCr15 with a length of 100 mm, a width of 10 mm, and a thickness of 5 mm. Two opposite steps are respectively arranged at both ends of the measuring tool 1. The ends of the two steps and the steps at the end form a total of four Dimensions a, d; b, c. A through hole 2 is provided in the middle of the material 1 .

[0012] There are printing places 3 at the four sizes of the material.

[0013] A set of clearance and surface difference combined measuring tools consists of 7 pieces, and there are 7 groups of different gap and surface difference sizes. It can measure 14 common gap sizes and 14 common surface difference sizes.

Abstract

The invention provides a gap and surface difference combination measuring tool for a vehicle body. The combination measuring tool is made by a GCr15 of which the length is 100 millimeters, the width is 10 millimeters and the thickness is 5 millimeters; the two ends of the measuring tool are respectively provided with two opposite steps; the end heads of the two steps and end head stairs form four sizes, namely a, d, b and c; and a through hole is formed in the middle of the measuring tool; the end head sizes, namely a and d, are used for measuring the size of the gap; the end head stair sizes, namely c and b, are used for measuring the size of the surface difference; and a group of gap and surface difference combination measuring tool consists of seven parts, has seven groups of different gap sizes and surface difference sizes and can be used for measuring 14 kinds of commonly used gap sizes and 14 kinds of commonly used surface difference sizes. The combination measuring tool combines the gap sizes and the surface difference sizes, can be used for measuring two indexes, and is convenient, practical and low in cost.

Description

technical field [0001] The invention relates to a measuring tool, in particular to a combined tool for measuring the gap and surface difference of a vehicle body. Background technique [0002] With the continuous increase of my country's automobile production and the rapid development of the body manufacturing industry, corresponding quality inspection tools are needed. [0003] Body clearance and surface difference are two important indicators in body quality inspection. Usually, the gap and the gap are measured with two different tools. There is no special inspection tool for measuring the gap, and it is inconvenient and inaccurate to use a vernier caliper instead. Contents of the invention [0004] The purpose of the present invention is to simultaneously measure the vehicle body gap and surface difference, and proposes a vehicle body gap and surface difference combined measuring tool. [0005] For this reason, the technical solution of the present invention is a comb...
