1. A quick-change device for a filling adapter for filling vehicles on assembly lines, on which circuits and containers of the vehicles are filled with operating materials which, starting from a filling system, are provided into the respective circuits and containers via hose assemblies with pneumatic and hydraulic lines and a filling adapter, the quick-change device comprising:
a separate connection plate arranged at a separation point of the hose assembly from the filling system to which all pneumatic and hydraulic lines are connected, which are connected to the filling system via bores and seals, and
a connection block designed as a functional counterpart to the connection plate on the filling system, wherein the connection plate and the connection block have a congruent bore pattern, so that, in the assembled state, flow paths of identical contour are formed in the connection area of the connection plate and the connection block, wherein:
the connection block includes a continuous channel structure along its central longitudinal axis, in which structure a tie rod is arranged, and in that an assembly with a pneumatic cylinder is arranged on the connection block on the end face opposite the connection plate, wherein the tie rod is enclosed in the channel structure on a section of its axial extension by a spring assembly which is supported in a fixed position on the tie rod at its two end face sections by a respective fastening element, wherein the pneumatic cylinder includes a piston surface with which the upper end face of the tie rod can be acted upon, wherein the tie rod has, at its end section opposite the pneumatic cylinder, a receiving geometry in the form of a cylinder screw, wherein the connection plate has a receiving geometry in the form of an elongated hole in such a way that the connection plate can be hooked to the tie rod, in that this receiving geometry with respect to the longitudinal axis of the tie rod passes in the radial direction from a section with a first open cross section in the form of the receiving geometry formed as a cylinder screw on the tie rod into a section with a second open cross section which has a narrower contour opening than the first open cross section and an undercut, and wherein the inner installation space of the undercut has a contour in the form of the cylinder screw formed on the tie rod.
