The four sets of workpiece rotating mechanisms 20 are arranged in the middle of four sides of a square, and the workpiece rotating mechanisms 20 comprise a bottom plate 210, a side frame 220, a mounting frame 230 and a first motor 240. The two sets of side frames 220 are respectively fixed on two sides above the bottom plate 210 through bolts, the mounting frame 230 is rotatably arranged between the two sets of side frames 220, and the first motor 240 is mounted on one set of side frames 220 to drive the mounting frame 230 to rotate. The workpiece fixture 30 includes a seat plate 310, a bracket 320, a clamp assembly 330, and a first positioning frame 340. The seat plate 310 is fixed above the mounting frame 230 by bolts, and the first positioning frame 340 is fixed at the rear side above the seat plate 310 by bolts. The clamping assembly 330 is mounted on the front side of the seat plate 310 to cooperatively clamp the component 40 with the first positioning frame 340. The bracket 320 is positioned between the first positioning frame 340 and the clamping assembly 330, and the component 40 is placed over the bracket 320. The rotary hole position detecting mechanism 50 is located at the center of the four sets of workpiece rotating mechanisms 20, and the rotary hole position detecting mechanism 50 rotates to sequentially detect the hole positions on the parts 40 after the workpiece fixing mechanism 30 is fixed.
Four operators respectively stand outside the four sets of workpiece rotating mechanisms 20.

At this time, the detection area of the rotary hole position detection mechanism 50 is moved above the component 40 to detect the hole position processed in the previous step. When one surface of the component 40 is detected to be qualified, the first motor 240 drives the mounting frame 230 to rotate 90 degrees, that is, drives the component 40 above the seat plate 310 to rotate 90 degrees to change the plane upwards, and the rotary hole position detection mechanism 50 can detect the other surface of the component 40. The above operation is repeated until the holes on the parts 40 are qualified, and the rotary hole position detecting mechanism 50 rotates to the position above the parts 40 in front of the second operator to detect the holes. At this time, the first operator can hold the welding gun to perform the welding operation on the component 40, the first motor 240 drives the component 40 to rotate to change the surface, and the operator can perform the welding operation on the multiple surfaces respectively. After the welding is finished, the welded part 40 is taken down, a new part 40 is put in again, and after the rotary hole position detection mechanism 50 rotates for one circle, the part 40 rotates to the upper part for hole position detection operation. Compared with the traditional hole site detection and welding mode, the welding inspection workbench can be used for combining hole site detection with welding and performing four-person rapid switching operation in turn, so that the speed of hole site detection processing and welding detection processing is greatly improved.

Similarly, when the operator holds the welding gun with his hand to perform the welding operation, the operator can also control the first motor 240 to drive the component 40 on the mounting frame 230 to rotate 90 ° each time through the control switch, so as to facilitate the welding operation on multiple surfaces of the component 40.

The second motor 520 drives the mechanical arm 530 to rotate, that is, drives the mounting plate 540 on the top of the mechanical arm 530 to move above the component 40, and the detection sensor 550 below the mounting plate 540 can detect the hole position on the component 40. The second motor 520 drives the mechanical arm 530 to rotate, and each time the mechanical arm 530 rotates 90 ° before the next operator, the second motor 520 drives the mechanical arm 530 to rotate, and the control switch before the operator can control the rotation operation.
