The inner part of the rotating main shaft 1 is movably sleeved with a pull rod 9, one end, close to the flange seat 5, of the pull rod 9 is provided with a flat key groove 10, one end of the rotating main shaft 1 is provided with a double nut lock 11, and one end, close to the double nut lock 11, of the pull rod 9 is movably sleeved with a paired belleville spring 12.
The end of the thin cylinder 2 is provided with a distance adjusting screw locking nut 201.
The output end of the rotary cylinder 3 is provided with an L-shaped positioning block 301.
The spring housing 7 is provided with an excircle positioning guide and a conical surface folding open slot.
The screw thread of the inner hole of the spring sleeve 7 is screwed into the pull rod 9 and the spring sleeve seat 6 to reserve a clearance of 1 mm.
The working principle is as follows: presetting, namely preparing a precise spring sleeve 7 with a matched size according to the sizes of plungers 4 with different specifications to be processed, and specifically operating as follows:
through the reversing air valve, the ejector rod of the thin cylinder 2 at the tail part is ejected out, the end part of the pull rod 9 at the position of the double nut locking 11 is pushed, the paired belleville springs are compressed, for example, the compression is 5mm, 6mm, 7mm and the like and can be adjusted at will, the compression displacement can be adjusted through a distance adjusting screw and a locking nut at the position of the ejector rod of the thin cylinder 2, and the compression displacement, namely the tension applied to the spring sleeve 7 by the belleville spring through the pull rod 9, is large.
And (3) a charging clamping process: the reversing air valve is controlled to enable the thin cylinder ejector rod to eject/retract, the pull rod is pushed/pulled reversely, the butterfly spring force is compressed/released, the spring sleeve is ejected/retracted through the guide of the pull rod flat key groove, at the moment, the processed piece plunger can be fed through a manual or automatic feeding device, and then the cylinder is rotated to position, so that the feeding, positioning, folding and clamping functions are realized.
The inner hole thread of the precise spring sleeve 7 is screwed into the pull rod 9 and the spring sleeve seat 6 (a clearance of 1mm is reserved), the spring sleeve 7 has an excircle positioning guide and a conical surface folding open slot, the end of the pull rod 9 is provided with a flat key slot 10 and a flat key, the spring sleeve 7 can be prevented from rotating in the pull rod 9 in the screwing process, and the pull rod 9 is ensured to play a positioning guide role in transverse left and right displacement.
And the top rod of the tail thin cylinder 2 is retracted through the reversing air valve, the pull rod 9 tensions the precise spring sleeve 7 under the action of the force of the belleville spring, the magnitude of the tensioning force is 5mm-1mm which is equal to 4mm of belleville spring pre-pressing force, and the pre-adjustment is finished.
The process of pneumatic loading and unloading of the plunger 4 of the processed workpiece comprises the following steps:
