Then, when the clamping block on the sliding column is aligned with the positioning groove, move the auxiliary rod in a direction close to the clamping plate. When the clamping block completely slides out of the positioning groove, drive the clamping block on the sliding column to rotate to the position of the clamping groove by rotating the auxiliary rod. The spring is in a stretched state during this process. After releasing the hand on the auxiliary rod, at this time, under the telescopic acting force of the spring, drive the clamping plate to slide into the clamping groove to fix the clamping plate. By providing a clamping device, the fixing of multiple circuit boards is achieved, the welding efficiency is improved, and the problem that the circuit board shakes during the welding process, resulting in poor welding effect, is prevented.

[0021] In the present utility model, after the fixing between the clamping plate and the support plate is completed, first rotate the rotating ring. When the bottom surface of the support plate faces upward to expose the bottom surface of the circuit board, then rotate the screw upward. The screw drives the extrusion block to fully squeeze and contact the rotating ring to fix the rotating ring. By providing a rotating device, it is convenient for the bottom surface of the circuit board to face upward and the welding efficiency is improved. Description of the Drawings

By providing the clamping device 3, multiple circuit boards 5 can be fixed, the welding efficiency can be improved, and the problem that the circuit board 5 shakes during the welding process, resulting in poor welding effect, can be prevented. An extrusion plate 304 is fixedly connected to the surface of the clamping plate 303.

[0032] The working principle of a PCBA board processing and testing tooling provided by the present utility model is as follows. When it is necessary to process and test the circuit board 5, first move the auxiliary rod 310. At this time, the clamping block 315 on the sliding column 309 driven by the auxiliary rod 310 completely slides out of the clamping groove 313. Then rotate the auxiliary rod 310 to drive the sliding column 309 to rotate. When the clamping block 315 on the sliding column 309 rotates to a position corresponding to the positioning groove 317, then move the auxiliary rod 310 in a direction away from the clamping plate 305. When the sliding column 309 completely slides out of the sliding groove 316, the spring 312 is in a compressed state during this process, releasing the fixing effect on the clamping plate 303. When turning the clamping plate 303 upward, release the hand on the auxiliary rod 310, exposing the limiting groove 306 on the support plate 301. Place a plurality of circuit boards 5 in the limiting grooves 306 on the support plate 301. Then turn the clamping plate 303 downward. When the clamping plate 305 on the clamping plate 303 rotates to the position corresponding to the sliding column 309, and at the same time move the auxiliary rod 310 in a direction away from the clamping plate 305. The spring 312 is in a compressed state during this process. Then when the clamping block 315 on the sliding column 309 is aligned with the positioning groove 317, move the auxiliary rod 310 in a direction close to the clamping plate 305. When the clamping block 315 completely slides out of the positioning groove 317, drive the clamping block 315 on the sliding column 309 to rotate to the position of the clamping groove 313 by rotating the auxiliary rod 310. The spring 312 is in a stretched state during this process. After releasing the hand on the auxiliary rod 310, at this time, under the telescopic acting force of the spring 312, drive the clamping plate 305 to slide into the clamping groove 313 to fix the clamping plate 303.

[0033] In the present utility model, after the clamping plate 303 and the support plate 301 are fixed, first rotate the rotating ring 41. When the bottom surface of the support plate 301 is upward and exposes the bottom surface of the circuit board 5, then rotate the screw rod 43 upward.
