[0033] Refer to Figure 2 - Figure 3The connecting block 41 is fixedly connected to the upper surface of the sliding rod 36, the sliding rod 36 drives the connecting block 41 to move synchronously when sliding, the other end of the spring 1 43 is fixedly connected to the lower surface of the floating block 44, the other end of the spring 2 46 is fixedly connected to the right inner wall of the connecting block 41, the lower surface of the sliding block 45 is inclined, and extruding the inclined surface of the sliding block 45 can make the sliding block 45 slide in the inner wall of the connecting block 41 and extrude the spring 2 46 in the sliding process.

The sliding rod 36, the connecting block 41, the sliding groove 301 and the through groove 302 are provided with four groups, and the four groups of the sliding rod 36, the connecting block 41, the sliding groove 301 and the through groove 302 are arranged in a circumferential array with the center of the rotating disc 33. The synchronous opening and closing of the four groups of the sliding rod 36 and the connecting block 41 can clamp the circuit board, and the stability of the position of the assembly during tightening is ensured.

[0034] Working principle: when the device is used, first start the motor 31, the output shaft of the motor 31 drives the rotating rod 32 to rotate, thereby driving the rotating disc 33 to rotate synchronously. When the rotating disc 33 rotates, the inner wall of the sliding groove 301 extrudes the outer wall of the sliding rod 36, thereby driving the sliding rod 36 to slide in the inner wall of the through groove 302, thereby driving the four groups of connecting blocks 41 to move synchronously, so that the four groups of connecting blocks 41 open and close synchronously. When the four groups of connecting blocks 41 are opened and closed to the appropriate position, the circuit board to be tightened is placed above the floating block 44, and then the motor 31 is started to drive the four groups of connecting blocks 41 to clamp synchronously, thereby completing the clamping and positioning of the circuit board, ensuring the stability of the position of the circuit board during tightening, and improving the precision and quality of tightening.

[0035] After clamping, start the automatic tightening device 2 to install the bolt on the circuit board. During the tightening of the bolt, the circuit board will be subjected to a certain degree of downward pressure.

When the connecting block 41 clamps and positions the circuit board, the inclined surface of the sliding block 45 will resist the circuit board to prevent the circuit board from being raised and shaken upward, thereby ensuring the stability during processing.

[0036] Finally, when the circuit board processing is completed, the motor 31 is started to drive the four groups of connecting blocks 41 to open synchronously, thereby releasing the clamping of the circuit board, and then the tightened circuit board is taken out.
