[0035] In the embodiment of the present invention, there are three compact pneumatic slides 1 .

[0036] The compact pneumatic slide 1 includes a piston cylinder 10, a connecting rod, a mounting base 15, a linear slide 12 and a slide 13. The mounting base 15 is fixed on the fixture base 5. The piston cylinder 10 is mounted inside the mounting base 15. One end of the cylinder barrel of the piston cylinder 10 is fixed to the fixture base 5 through a connecting piece 9. One end of the piston rod of the piston cylinder 10 is hinged to the connecting rod, and the other end of the connecting rod passes through the mounting base 15 and is fixed to the slide 13. Two linear slides 12 are fixed on the top of the mounting base 15. The slide 13 is slidably mounted on the linear slides 12 to realize the in-position limit function of the slide 13.

[0037] A buffer 11 is also fixedly mounted on the top of the mounting base 15 and is connected to the slide 13 ; during the displacement of the slide 13 , the buffer 11 effectively absorbs the impact force generated, thereby reducing damage to the equipment and extending the service life of the equipment.

The L-shaped mounting seat 14 is fixed to the slide 13, and the Y-adjustment mounting plate 19 is fixed to the vertical plate of the L-shaped mounting seat 14. The Z-adjustment mounting plate 18 is fixed to the inner side of the Y-adjustment mounting plate 19.

The shell weld side clamping device 28 is installed at one end of the lever pressure arm of the second dedicated clamping cylinder 30. During the welding process, the rotation of the second dedicated clamping cylinder 30 drives the shell weld side clamping device 28 to move toward the side of the weld and apply a certain clamping force to keep the shell stable during the welding process and prevent the weld from deforming and cracking. The auxiliary clamping mechanism 3 has an XYZ three-dimensional gasket precision adjustment function, which can effectively ensure the upper and lower shells of the stainless steel Y-tube assembly are tightly fitted and improve its welding quality.

[0042] An operating button box 6 is also fixed on the clamp base 5 to facilitate manual operation of the opening and clamping actions of the cylinders of each positioning and clamping mechanism.

[0043] A compressed air triplet 8 and an air-controlled valve unit 7 are fixedly installed on the outside of the clamp base 5.

[0044] Working principle:

[0045] In an embodiment of the present utility model, a Y-shaped workpiece is placed in the device. The piston rods of the piston cylinders in each compact pneumatic slide extend and retract, driving the slide to move along the slide rail, thereby pressing the XYZ three-way adjustable split pin assembly fixed to the slide into the special-shaped hole of the Y-shaped workpiece. Subsequently, the first dedicated clamping cylinder rotates, driving the rotation of the upper shell contour block, which cooperates with the lower shell contour block to achieve compression of the workpiece shell to ensure compression accuracy. Subsequently, the second dedicated clamping cylinder is activated, and the second dedicated clamping cylinder rotates, driving the shell weld side clamping device to move toward the side of the weld and apply a certain clamping force to keep the shell stable during the welding process and prevent weld deformation and cracking.
