Detailed Description

The invention is further described with reference to the following specific drawings and examples.

Because the last sensor joint of automobile exhaust purifier is not embedded structure with the joint hole assembly, is inclined plane laminated structure as figure 1, and the fitting surface is the inclined plane, so need guarantee to connect the axiality between inspection hole and barrel joint hole, make detecting element assemble smoothly, reach near the carrier of barrel inside and detect, here the utility model discloses whether need detect one process axiality and satisfy the requirement on the positioner, if the manual trompil in appearance stage, also can detect the hole site and have or not if the burr.

As shown in FIGS. 2-5: the utility model provides a welding position device, wherein: comprises an air inlet component 1 and an air outlet component 2; the air inlet assembly 1 is rotationally connected with the air outlet assembly 2; a sensor joint 3 is arranged on the air outlet component 2; a positioning component is arranged in the sensor joint 3.

Wherein: the air outlet assembly 2 comprises a first air outlet assembly 21, a transition part 22 and a second air outlet assembly 23 from left to right in sequence; the sensor connection 3 is arranged on the transition 22.
