[0031] The application provides a positioning tool for train coupler machining with adjusting clamping head 22, specifically, when using, first, the whole tool is installed on the device outside through fixed seat 1, the installation mode can be welding or bolt installation, then, the positioning work can be used, first, the coupler to be processed is placed in the center position of placing disc 3, then, according to the different appearance of the coupler to be clamped, it is clamped,

[0032] Need to start driving main part 4, so that it drives rotating screw rod 24 to rotate, and then make rotating screw rod 24 and moving seat 25 be connected by thread, so that moving seat 25 drives adjusting clamping head 22 at its top to move towards, so that the clamping work of arc surface and plane can be completed under the action of adjusting clamping head 22,

[0033] When adjusting clamping head 22 clamps, according to the different clamping positions of the surface of the coupler, adjusting main body 23 can also be started, so that the position of adjusting clamping head 22 is adjusted, so that the effect of clamping positioning at different positions is achieved.

[0034] Among them, according to Figures 1-4 As shown in the figure, the inside of fixed seat 1 is hollow structure arrangement, and the top is provided with reserved slot 11 at equal angle, and the position and number of reserved slot 11 correspond to the position and number of clamping main part 2.
