Before actual use, the electrode 23 on the movable clamp arm 22 is usually far away from the electrode 23 on the static clamp arm 21, which is represented on the multistage supercharging cylinder 3, namely, as a state diagram shown in fig. 3, when the pre-stroke piston 35 is positioned at the leftmost side of the cylinder 300, and the working piston 37 is positioned at the rightmost side of the cylinder 300;

when the pre-working stroke is carried out, the double-stroke cylinder 31 and the working piston rod 38 inside the double-stroke cylinder move leftwards together, so that the compression spring 74 pushes the tapered sliding sleeve 73 to move leftwards, and then the locking ball 71 is pressed into the ball groove 72 of the front end cover 301 under the abutting action of the large end of the tapered sliding sleeve, so that the cylinder body 300 of the double-stroke cylinder 31 is fixed relative to the pre-stroke piston rod 36, and the state diagram shown in fig. 4 is achieved. Specifically, by pressurizing the left side of the pre-stroke chamber 33 (i.e., venting the right side of the pre-stroke chamber 33), with the pre-stroke piston rod 36 fixed, the cylinder 300 moves to the left; at this time, a pre-working stroke is performed, that is, a process from the far to the near of the electrode 23 on the forceps arm 22 is followed by a process in which the working piston rod 38 moves to the left, because a sufficient stroke needs to be reserved for the left movement of the working piston rod 38, before the pre-working stroke is performed, the working piston 37 needs to be located at the right side (preferably the rightmost side) of the cylinder 300, so that the working piston rod 38 is driven by the partition plate 303 to move to the left together;

when the pre-working stroke is completed, the pre-stroke piston rod 36 is locked relative to the cylinder 300; at this time, the right side of the working chamber 34 is pressurized (correspondingly, the left side of the working chamber 34 is exhausted), as shown in fig. 4, the working piston rod 38 continues to move leftward, and the left end portion (i.e., the outer end portion) of the working piston rod 38 drives the movable clamp arm 22 to move while overcoming the pressure of the compression spring 74, so that the electrode 23 fixed thereon is close to the electrode 23 on the fixed clamp arm 21, and a larger pressure is applied to press the middle workpiece to be welded, so as to perform the welding operation, and enter the state diagram shown in fig. 5;

on the contrary, when the welding is completed, the pressure is applied to the left side of the working chamber 34 (correspondingly, the air is exhausted from the right side of the working chamber 34), and at this time, the working piston rod 38 moves rightward, and returns to the state shown in fig. 4; the left side pressure of the working chamber 34 is maintained, the right side of the pre-stroke chamber 33 is pressurized (i.e. the left side of the pre-stroke chamber 33 is exhausted), the cylinder 300 can only move away to the right side under the condition that the pre-stroke piston rod 36 is fixed, so as to drive the working piston rod 38 to move rightwards together, the resetting fastener 75 fixed on the working piston rod 38 drives the tapered sliding sleeve 73 to move rightwards, so that the locking ball 71 loses pressure and is separated from the ball groove 72, and under the condition that the pre-stroke piston rod 36 and the cylinder 300 are unlocked, the double-stroke cylinder 31 can return to the state diagram shown in fig. 3, so as to facilitate the next welding operation.

The present embodiment is configured such that the plurality of locking balls 71 are uniformly circumferentially spaced, the same number of ball grooves 72 are also provided on the inner circumferential side wall of the front cover 301, and it is more preferable that the plurality of ball grooves 72 are integrally connected to form an annular ball groove.

In the present embodiment, the reinforced cylinder 32 includes a pressurizing cylinder body 320, a pressurizing cavity 321 disposed in the pressurizing cylinder body 320, a pressurizing piston 322 disposed in the pressurizing cavity 321, and a pressurizing piston rod 323 fixed to the pressurizing piston 322. The pressurizing cylinders 320 of two adjacent reinforcing cylinders 32 are divided by a common end cover 324, so that the use of parts and the structural size can be saved, and the outer walls of a plurality of reinforcing cylinders 32 connected in series in sequence are tightened by bolts. Of course, the rightmost one may be the common end cap 324, which makes it easier and easier to pressurize the number of reinforced cylinders 32, while in this embodiment, a one-sided end cap 325 is provided for enclosing the edgemost one of the reinforced cylinders 32.

In this embodiment, the pressurizing piston rods 323 are hollow, so that an axial airflow channel is formed inside the pressurizing piston rods 323, and meanwhile, the right end of each pressurizing piston rod 323 is penetratingly disposed on the pressurizing piston 322 for pushing the pressurizing piston to move, and the pressurizing piston rods 323 and the pressurizing piston 322 are fixedly connected relatively. The output end (left end) of the boosting piston rod 323 penetrates through the end cover 324 on the left side of the boosting piston rod 323, and then is connected with the right end of the boosting piston 322 in another reinforcing cylinder 32 on the left side of the boosting piston rod, so that the boosting piston rods 323 of two adjacent reinforcing cylinders 32 are connected and communicated with each other; meanwhile, the output end (left end) side wall of the pressurizing piston rod 323 is provided with an air outlet groove communicated with the hollow axial air flow channel, so that air flow can flow out of the air outlet groove to the other strengthening cylinder 32 on the left side to provide pressure for the pressurizing piston 322 of the strengthening cylinder 32 on the left side, as shown in fig. 5.

Thus, after the rightmost one of the reinforced cylinders 32 is charged (charged at the right side of the booster piston 322 thereof), the air flow applies a leftward moving pressure to the booster piston 322 thereof in the first direction, and flows leftwards through the booster piston rod 323 thereof and flows out from the air outlet groove at the output end (left end) portion of the booster piston rod 323 thereof into the other reinforced cylinder 32 at the left side thereof, specifically, to the right side of the booster piston 322 in the reinforced cylinder 32 at the left side thereof, and the air flow applies a leftward moving pressure to the booster piston 322; at the same time, the air flow continues to the more left reinforcement cylinder 32 to provide a leftward pressure, and so on, the plurality of reinforcement cylinders 32 simultaneously apply a leftward thrust. The leftmost reinforcement cylinder 32, which pressurizes the air flowing out of the output end (left end) of the piston rod 323, can provide a pushing force to the right side surface of the working piston 37, so that the working piston moves to the left, and drives the clamp arm 22 to have a greater pressure.

It can be understood that, in order to prevent the electrode 23 from being worn due to long-term use, and the problem that the pressure applied to the workpiece by the electrode 23 is insufficient due to the shortened electrode 23, the working chamber 34 and the pressurizing piston chamber 321 are provided with a certain margin in length, so that the working piston 37 and the pressurizing piston 322 can provide enough pressure without moving to the leftmost side, and therefore, after the electrode 23 is worn, the working piston 37 and the pressurizing piston 322 can also make up for the problem of insufficient pressure due to the wear of the electrode 23 by continuing to move to the left.
