A kind of rolling stock drawing pull bar, node pressure tire, it is characterized in that: comprise bottom sheet plate, be divided into two cylinder bodies at bottom sheet plate two ends, be built in the lower positioning sliding block in cylinder body and upper holder block corresponding with lower positioning sliding block in vertical direction, described lower positioning sliding block bottom surface is provided with groove and is provided with back-moving spring between described groove floor and bottom sheet plate, described lower positioning sliding block upper surface is provided with the locating hole communicated with described groove, described locating hole is in the Long Circle corresponding with node end, described cylinder body top sidewall is provided with the stop screw of corresponding lower positioning sliding block, inboard wall of cylinder block is separately provided with guided way, described lower positioning sliding block outer peripheral face is provided with the gathering sill of corresponding guided way, described upper holder block is provided with stepped centre bore.
Above-mentioned rolling stock drawing pull bar, node pressure tire, the pore size maxima of the stepped centre bore of described upper holder block is less than the diameter of the metal sheath of node, the height of described upper holder block is equal to the vertical range of its metal sheath with node top, synchronously moves down to make node top and its metal sheath.
Above-mentioned rolling stock drawing pull bar, node pressure tire, described lower positioning sliding block top is provided with the boss identical with the node holes aperture of drawing pull bar, to locate press-fiting in ingress hole of protracting.
Above-mentioned rolling stock drawing pull bar, node pressure tire, the number of described stop screw is two or more, and the number of described guided way and gathering sill is more than one.
The beneficial effects of the utility model are:
1, be fixedly connected with two cylinder bodies by a yoke plate, ensure that the interior nodes end flat keeping parallelism of drawing pull bar two stomidium;
2, inboard wall of cylinder block is provided with guided way, while this ensures that thering the upper and lower motion of lower positioning sliding block, side-to-side movement have also been obtained effective control, node is press fit into downwards in the node holes of drawing pull bar stably, prevent press-fiting process interior joint radial direction and beat occurs, do not need beat table centering, disposable press-fit namely meet the requirements of effect;
3, upper holder block is enclosed within outside node top in use, and ensure that node top connects with forcing press with upper holder block simultaneously, upper holder block lower surface contacts with node metal crust, and node top and metal sheath, simultaneously toward pressing down, avoiding the phenomenon damaging node and occurring;
4, take out drawing pull bar after press-fiting, lower positioning sliding block automatically resets under the effect of back-moving spring, convenient and practical, simple to operate, one-shot forming, press-fit efficiency high, press-fit accurate height.
