Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0019] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] like Figure 1 As shown, the piston rod head welding tool of the utility model includes a workbench 1, on which a piston rod bracket 2 and a rod head fixing mechanism are installed. There are two piston rod brackets 2, and the two piston rod brackets 2 are arranged correspondingly, and the two piston rod brackets 2 are arranged in coordination with the rod head fixing mechanism.

[0022] like Figure 2 As shown, the piston rod bracket 2 includes a support rod 21, the top of the support rod 21 is provided with an arc-shaped groove 22, and the surface of the arc-shaped groove 22 is also provided with two corresponding mounting grooves 23. A roller 25 protruding from the inner surface of the arc-shaped groove 22 is rotatably installed in the mounting groove 23 through a rotating shaft 24. The rollers 25 in the two mounting grooves 23 are correspondingly arranged, so that when the piston rod is placed on the two piston rod brackets 2, the piston rod can rotate when subjected to force; the rollers 25 are made of elastic rubber to prevent damage to the surface of the piston rod during welding.

[0023] like Figures 1 - 3 As shown, the rod head fixing mechanism includes a "door"-shaped support frame 3 fixedly mounted on the workbench 1, a stud 4 is fixedly mounted on the workbench 1 inside the support frame 3, a screw sleeve 51 is threadedly connected to the top of the stud 4, a round table 5 is provided on the top of the screw sleeve 51, and the screw sleeve 51 is rotated by rotating the round table 5 to adjust the depth of the stud 4 screwed into the screw sleeve 51, thereby adjusting the height of the round table 5, and a locking nut 52 is also installed on the stud 4 below the screw sleeve 51. After the round table 5 is adjusted into place, the position of the screw sleeve 51 on the stud 4 can be fixed by the cooperation of the locking nut 52 and the screw sleeve 51.

[0024] A slide groove 31 is provided on the support frame 3 above the truncated table 5, and a slider 6 is movably installed in the slide groove 31. The slider 6 is provided with a convex ridge 61, and the convex ridge 61 enables the slider 6 to be clamped on the slide groove 31 and slide in the slide groove 31. A screw rod 7 passing through the slider 6 is provided above the truncated table 5, and the screw rod 7 is threadedly connected with the slider 6.

The top of the cone 8 is vertically downward, and the cone 8 can press the piston rod head 10 on the truncated table 5, so that the piston rod head 10 is pressed against the truncated table 5. The cone 8 is made of plastic material to prevent the cone from wearing the piston rod head.

[0025] likeFigure 4 As shown, when the welding tooling is in use, place the piston rod 9 on two piston rod brackets 2, and then place the piston rod head 10 on the frustum 5. Adjust the height of the piston rod head 10 by rotating the frustum 5 so that the piston rod head 10 is at the same height as the piston rod 9, and use the lock nut 52 to fix the height of the frustum 5. Then, rotate the cone down by the handle 71 so that the cone is inserted into the piston rod head to achieve the positioning and pressing of the piston rod head, and then welding can begin. After welding the upper part is completed, move the cone out of the piston rod head by the handle 71, then move the entire piston rod to one side of the piston rod bracket 2 so that the piston rod head moves out of the frustum 5, and with the assistance of the roller 25, rotate the piston rod 9 to complete the welding of the remaining part; just remove it directly after welding is completed.

[0026] The height of the frustum 5 of this tooling is adjustable, and the component for pressing the piston rod head 10 is a cone 8, enabling it to be used for the welding operations of piston rod heads 10 of various models.
