The working principle of the invention is as follows:

the automatic tightening device is used for an automatic tightening workstation of a clamping spring of a middle assembly of a turbocharger, when a transmission line tray drives a workpiece to move to a station, a blocking cylinder blocks the tray, and a lifting mechanism lifts the tray to separate from a wire body. Then, the clamp spring automatic installing mechanism judges the type of the clamp spring, the sliding rail clamp 26 is loosened under the control of a program, the clamp spring type switching electric cylinder 24 drives the bolt mechanism to move to a corresponding position, and then the sliding rail clamp 26 is locked, so that the preparation work of automatically installing the clamp spring is completed.

As shown in fig. 7, the front and rear transplanting electric cylinders 2 drive the base 1 to move forward along the front and rear moving slide rails 5 to a position close to the conveying line tray. After the front and back transplanting electric cylinder 2 stops, the front and back transplanting air cylinders 7 of the supporting claws extend out, so that the supporting claws 10 are inserted into openings of the clamp springs, and then the clamp spring supporting air cylinders 8 are opened to drive the supporting claws 10 to open the clamp springs. Two ends of the clamp spring opening are opened to two sides by a certain angle along with the supporting claws 10, so that the position consistency of the clamp spring pin is ensured, and preparation is made for inserting the clamp spring pin into the clamp spring pin hole next. Next, the lifting cylinder 14 extends out to drive the lifting frame 12 to fall down and abut against the bolt limiting bolt 21, and at the moment, the two clamping claw pins 29 just fall down and are inserted into the pin holes at the two ends of the clamp spring opening, so that the position of the clamp spring pin opening is locked. And then the clamp spring supporting cylinder 8 retracts, the supporting claw 10 is separated from the clamp spring 41, and the supporting claw front and back shifting cylinder 7 retracts, so that the clamp spring supporting mechanism retracts to give way for the bolt mechanism, and the clamp spring is conveniently installed in the next step. Then the clamping jaw shifting cylinder 28 retracts, so that the clamping jaw pin 29 drives the clamp spring 41 to move towards the middle and tightly, and the outer diameter of the clamp spring is reduced to be smaller than the clamp spring notch on the end face of the pressing shell. Then the front and back transplanting electric cylinder 2 drives the base 1 to move forward for a distance again, so that the outer diameter of the tight clamp spring is completely positioned above the central aperture of the pressing shell 42, then the bolt height limiting cylinder 18 retracts, the lifting frame 12 continuously falls onto the clamp spring mounting in-place limiting bolt 22, and the clamp spring 41 falls into the pressing shell 42 and is positioned at the same height with the clamp spring groove in the pressing shell 42. Then the clamping jaw transferring cylinder 28 extends out, so that the clamping jaw pin 29 with the clamp spring 41 moves towards two sides, the clamp spring 41 is plugged into the clamp spring groove of the pressing shell 42, and then the air pressure of the unloading clamping jaw transferring cylinder 28 is released. At this time, a displacement value, which is the snap spring opening size after the snap spring is assembled, is recorded, as shown in fig. 8.

Then the bolt height limiting cylinder 18 extends out to enable the clamping claw pin 29 to rise above the pressing shell 42 to be separated from the clamp spring 41, then the front and back transplanting electric cylinders 2 drive the base 1 to return to the original position along the front and back moving slide rail 5, and then other cylinders return to the original position in sequence, so that the automatic assembly function of the clamp spring is completed.

The clamp spring automatic assembling device well solves the automatic assembling problem of the clamp spring, greatly improves the assembling accuracy and stability, and effectively improves the production efficiency.
