Abstract

This utility model provides a welding fixture for automotive parts with leak detection function, including a fixture base, a positioning mechanism, a first clamping mechanism, a second clamping mechanism, and a tightening mechanism. The positioning mechanism, the first clamping mechanism, and the second clamping mechanism are all located on the fixture base, respectively, on either side of the positioning mechanism. The tightening mechanism is located on the fixture base, above the first clamping mechanism. The tightening mechanism includes a tightening cylinder, a tightening positioning pin, a tightening positioning block, and a leak detection sensor. The tightening cylinder is connected to the tightening positioning block, and both the tightening positioning pin and the leak detection sensor are located on the tightening positioning block. This automotive parts welding fixture with leak detection function provides higher welding quality.
