[0002] A welding positioning block is a part used to achieve positioning during welding connection. It is usually made of metal material and can be used in different welding occasions. The welding positioning block can fix the workpiece, workbench, etc. together so that they will not move or shake during the welding process, thereby ensuring the welding quality.

[0003] At present, most positioning blocks used in welding processes require tools to adjust and fix the bolts on both sides of the positioning blocks multiple times, which is not only troublesome to operate but also inconvenient to disassemble and assemble. At the same time, traditional positioning blocks can only clamp conventional workpieces. If you encounter workpieces such as pipe fittings, you still need to replace the positioning blocks. The process is not only cumbersome but also affects the processing efficiency. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 , a movable positioning block for a welding fixture comprises a fixed base 1, a fixed positioning block 2 is installed on the upper end of the fixed base 1, movable clamping blocks 4 are respectively installed on both sides of the fixed positioning block 2 through fixed pins 3 and screws 6, and a positioning column 9 is screwed on the upper end of the fixed positioning block 2;

[0021] Furthermore, through holes are provided at the upper and lower parts of the fixed positioning block 2, in which a fixing pin 3 is installed through a bushing 8, and a threaded hole is provided in the middle part of the fixed positioning block 2, in which a screw 6 is screwed, and both sides of the screw 6 extend out of the movable clamping blocks 4 on both sides and are screwed with multiple adjusting nuts 7.

[0022] Each movable clamping block 4 is provided with a through hole at the upper and lower parts, a bushing 8 is provided in the through hole, and a fixing pin 3 is installed in the through hole to limit the position, and both ends of the fixing pin 3 extend out of the movable clamping block 4 respectively.

[0023] Moreover, the through holes formed in each movable clamping block 4 coincide with the center lines of the through holes formed in the fixed positioning block 2 .

[0024] In addition, movable clamping blocks 4 are respectively provided on both sides of the screw rod 6 , and a spring 10 is sleeved at the connection between the screw rod 6 and the movable clamping block 4 , and the spring 10 is respectively in compression contact with the fixed positioning block 2 and the movable clamping block 4 .

[0025] Meanwhile, an adjusting screw 91 is provided on one side of the positioning column 9 , and the positioning column 9 is mounted on the upper end of the fixed positioning block 2 through the adjusting screw 91 .

[0026] Furthermore, a pipe fitting 5 is provided at the upper end of the fixed positioning block 2 , and two sides of the pipe fitting 5 are clamped and fixed by movable clamping blocks 4 respectively.

[0027] In this embodiment, the positioning block can be fixedly installed on the corresponding platform through the fixed base 1 and fixed by bolts. When clamping the pipe fitting, the positioning column 9 is tightened into the screw hole at the upper end of the fixed positioning block 2, and the pipe fitting is placed on the fixed positioning block 2. The adjusting nuts 7 set on both sides of the screw rod 6 in the middle of the fixed positioning block 2 are tightened, so that the adjusting nuts 7 on one side drive the movable clamping block 4 to move, so as to change the opening size of the two movable clamping blocks 4, thereby clamping and welding the pipe fitting;
