An assembly detection device for an airbag and a steering wheel

Abstract

The invention provides an assembly detection device of an air bag and a steering wheel. The assembly detection device comprises a body, a go-no go fixed gauge and positioning devices, wherein the body is the same as the air bag in structure and shape, and the positioning devices are located on the left side and the right side of the bottom of the body. Each positioning device comprises a positioning base, a fixing base and a sliding pin, wherein the fixing base and the sliding pin are located on the inner side of the positioning base, a through groove is formed in the upper end face of the fixing base, sliding chutes are formed in the front end face and the rear end face of the fixing base, one end of the sliding pin is a cylinder, the top of the cylinder penetrates through the positioning base, the upper end and the lower end of the other end of the sliding pin are respectively provided with a positioning pin, the top ends of the positioning pins penetrate through the sliding chutes, and the sliding pin can move left and right along the sliding chutes and in the through grooves; a control handle is arranged on the upper portion of the body, and the bottom end of the control handle penetrates through through holes which are formed in the body and communicated with the through grooves to be connected with the sliding pins. In the process of measuring whether the assembly gap between the steering wheel and the air bag is qualified or not, the body is installed at the position, corresponding to the air bag, of the steering wheel, the assembly gap between the steering wheel and the air bag is detected through the go-no go fixed gauge, detection is convenient and quick to conduct, operation is simple, the detection result is accurate, and detection efficiency is improved.

Description

technical field [0001] The invention relates to a detection device, in particular to an assembly detection device of a safety airbag and a steering wheel. Background technique [0002] During the production process of the steering wheel, the clearance value between the steering wheel and the airbag needs to be inspected according to the specification requirements. Since these size points all exist on the curved surface of the inner edge of the steering wheel, it is impossible to detect them with general-purpose measuring tools, and they must be measured with three coordinates. With the increase of output, the frequency of inspection is constantly increasing, which makes the task of three-coordinate measurement very heavy. Moreover, using contact three-coordinates for measurement, the tolerance of the measurement points is large, the accuracy is not high, and the three-coordinates measurement takes a long time and the efficiency is low.
