(7) jack up a small distance h1 from workbench (14), the upper and lower end face of metallic plate (7) to be measured respectively with the second spin (37),
First spin (24c) sliding contact, control device control the side cylinder (41) to stretch out, drive the limiting plate (42) that will treat
Metallic plate (7) is surveyed to be limited in the middle part of workbench (14)；
Step 3, feeding：
Control device controls the synchronous belt conveying device (23) operating so as to which metallic plate to be measured (7) be driven to move forward, when treating
The welding position of survey metallic plate (7) stops when just exposing from workbench (14) front end；
Step 4 compresses：
Control device controls the mandril of the compression cylinder (36) to extend downwardly and metallic plate to be measured (7) is pressed in workbench (14)
On, control device controls the pre- air cylinder (35), lifting cylinder (21), side cylinder (41) to retract；
Step 5, impact：
Control device controls second driving motor (51) rotation, and passes through the second screw (52), the second spiro connecting piece (53)
Effect drives second sliding block (54) to be moved forward and backward to above metallic plate to be measured (7) front end, and control device controls the impact
Cylinder (55) quick washing metallic plate to be measured (7)；
Step 6, data collection and analysis：
The position of blow cylinder (55) is measured by laser range finder (61), obtain weld seam by operation rushes with blow cylinder (55)
Distance a little is hit, and passes through the power that pressure inductor (62) measures impact moment, rushing suffered by weld seam position is obtained by conversion
Hit torque；
Step 7, the material returned：
Control device controls the lifting cylinder (21) to rise again, and control the pre- air cylinder (35), side cylinder (41)
It stretches out, and then the compression cylinder (36) is controlled to retract, control device controls synchronous belt conveying device (23) operating, will treat
Metallic plate is surveyed to withdraw from from workbench (14) front or behind.
8. a kind of application method of metal welding position reliability detecting device according to claim 7, it is characterised in that：
In step 3, while control device controls synchronous belt conveying device (23) operating, first driving motor is also controlled
(31) it rotates, the pre- air cylinder (35) is made to advance forward with metallic plate to be measured (7) and is connected to metallic plate to be measured (7) always
On.
