The invention provides a mechanism for knotting a railway side wiring board before welding. The mechanism comprises a rack and a wire unwinding door. The wire unwinding door is connected with the rack, and a threading hole and a guide groove extending inwards from the threading hole along the butt joint surface are formed in the butt joint surface after connection. A positioning hole is further formed in the end surface of the butt joint surface of the rack and the wire unwinding door after connection. The direction of the positioning hole is perpendicular to the direction of the threading hole, and the positioning hole is communicated with the threading hole. A transmission device is arranged between the other end, opposite to the end face, of the wire unwinding door and the rack. A connecting device is arranged at one end of the transmission device on the rack. A wire clamping mechanism capable of being opened and closed is arranged on the rack on the outer side of the threading hole. According to a knotting mechanism provided by the invention, accurate positioning can be carried out, after the threading hole is subjected to wire conveying, a wire clamping plate can be controlledto clamp and loosen wires through a pneumatic device, and a motor drives a gear to open and close the wire unwinding door to finish the whole knotting process.
Description
technical field [0001] The invention relates to the technical field of railway supporting facilities, in particular to a mechanism for knotting a railway side terminal board before welding. Background technique [0002] At present, the welding of the side terminals of railway signals is mostly done by manual welding. It is necessary to manually thread the wires into the side terminal holes, and then manually twist the knot to complete the knot. Manual welding technology requires a lot of manpower, and the welding quality and accuracy cannot be guaranteed. . With the development of science and technology, human beings have higher and higher requirements for welding. Realizing automatic welding is an important aspect of current research. Automatic welding can reduce manual labor intensity, improve welding quality, and improve weld appearance and welding quality. In order to replace manual work with machines, relying on robotic arms for automatic welding has become an inevitab...
