Automatic testing equipment for testing the airtight performance of rim welds

Abstract

The invention relates to automatic detection equipment used for airtight performance detection of a rim welding line. The automatic detection equipment includes at least one set of detection unit of an identical structure, and each set of detection unit includes a lifting mechanism, a material taking mechanism, a plugging mechanism and a detection mechanism; the plugging mechanism includes mutually parallel upper tool and lower tool, and is used for plugging a wheel rim, the upper tool is vertically and fixedly connected on the lifting mechanism and synchronously rises and falls with the lifting mechanism, and the lower tool is fixedly connected on an equipment frame body; and the material taking mechanism includes a material taking rod used for driving the wheel rim to complete automatic feeding. The beneficial effects of the automatic detection equipment are that automatic taking and sending processes can be realized, a detection process only requires operating personnel to adjust a welding line position, a detection result is given directly through the equipment, and performance indexes are real and reliable.

Description

technical field [0001] The invention relates to the technical field of detection of automobile wheel rims, in particular to an automatic detection device for detection of the airtight performance of rim welds. Background technique [0002] The wheel rim is an important part of the driving system of the car. It is required that the welding quality of the butt joint weld seam should be reliable, the shape should be accurate, and it should have sufficient resistance to fatigue fracture. The quality of its manufacture directly affects the various safety performances of the wheels and even the entire vehicle. However, the manufacturing process of the wheel rim is complicated. After the round welding, it has to go through 11 machining processes such as one flaring, three rolling, and one expansion, and then enters the airtight testing stage. During this period, it is easy to cause weld joints to crack, Unqualified products such as open seams and small leaks. [0003] However, ho...
