Understandably, each of the fork blocks 455 is composed of two clamping plates, that is, the first clamping block 4552 and the second clamping plate 4553, when the driving shaft of the fork telescopic cylinder 454 extends by a thrust force, the fork supporting rod 4551 connected with the driving shaft and the pair of clamping plates connected with the fork supporting rod 4551 are driven to move in a direction approaching to the workpiece 5; and when the driving shaft of the shift fork telescopic cylinder 454 is returned by the pulling force, the shift fork supporting rod 4551 connected with the driving shaft and the pair of clamping plates connected with the shift fork supporting rod 4551 are driven to move in the direction away from the workpiece 5. Preferably, the front ends (the ends for pulling the workpiece 5) of the pair of clamping plates are T-shaped, and a first gap between the T-shaped front end of the first clamping plate 4552 and the workpiece 5 and a second gap between the T-shaped front end of the second clamping plate 4553 and the workpiece 5 are both 2-10 mm, and preferably, the first gap and the second gap are 5mm, so that the workpiece 5 can be conveniently positioned and pulled; and the connection mode of the pair of clamping plates and the shifting fork supporting rod 4551 is a snap connection, which is convenient for installation or disassembly and adjustment of the width between the pair of clamping plates.

Further, referring to fig. 1 and 5, as an embodiment of the welding positioning apparatus of the present invention, the shift fork transmission assembly 452 includes a shift fork sliding guide rail 4521 and a shift fork sliding cylinder 4522; the shift fork reference plate 453 is installed on the shift fork slide rail 4521, and the shift fork slide cylinder 4522 is connected to the shift fork reference plate 453; the shift fork slide cylinder 4522 drives the shift fork reference plate 453 to relatively slide along the shift fork slide rail 4521. Understandably, when the driving shaft of the shift fork telescopic cylinder 454 extends by the pushing force, at this time, the shift fork block 455 is close to the workpiece 5, the shift fork sliding cylinder 4522 drives the shift fork reference plate 453 to move along the positive direction of the shift fork sliding guide 4521 (i.e., the direction of transporting the workpiece 5), and drives the shift fork block 455 to move by the distance of one station along the positive direction, so as to shift the workpiece 5 to move to the next station by the shift fork block 455; when the driving shaft of the shift fork telescopic cylinder 454 mounted on the shift fork reference plate 453 returns by a pulling force, at this time, the shift fork block 455 is far away from the workpiece 5, and the shift fork sliding cylinder 4522 drives the shift fork reference plate 453 to move along the reverse direction of the shift fork sliding guide 4521 (i.e., the reverse direction of workpiece 5 transportation), so as to drive the shift fork block 455 to move by a distance of one station along the reverse direction, thereby keeping the station of the workpiece 5 unchanged, achieving the purpose of automatic flow line feeding and discharging, and improving the production efficiency. In another embodiment, the fork reference plate 453 is driven by a motor to improve the transport accuracy and the transport speed of the workpiece 5.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
