Process for assembling heat contact rod end part of billet hold-out rod

Abstract

The invention relates to the technical scheme of preventing the rotary offset of a headstock, in particular to a process for assembling a heat contact rod end part of a billet hold-out rod. The heat contact rod end part consists of a headstock (1), a carriage (2), a hexagon bolt (3), hexagon nuts (4) and an elastic washer (5). According to the technical scheme of the assembly process, a steel plate on the lower side of a guide slot formed on the upper part of the carriage (2) is widened, and threaded holes are tapped uniformly on the steel plate, so that the threaded holes are perpendicular to the upper surface and lower surface of the steel plate; and when the headstock (1) and the carriage (2) are assembled, the hexagon bolt (3) are screwed in from bottom to top, so that the hexagon bolt (3) runs through a bottom plate of the headstock (1), and the hexagon nuts are in transitional fit and screwed fixedly to prevent the bolt from loosening. By the process, the headstock is jacked between the lower surface of the steel plate on the upper side of the guide slot of the carriage and the end face of the bolt firmly by the bolt, so that a gap between a pulley and a guide rail is basically consistent, the situation of undersized gap and even interference is avoided, and the headstock runs smoothly up and down.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to an assembly process for the end of a hot contact rod of a billet supporting rod. Background technique [0002] Such as figure 1 As shown, the end of the hot contact rod of the existing steel billet support rod is mainly composed of the head frame part and the carriage part of the baler. The assembly is fixed by traditional nuts and bolts. In order to restrain the rotation tendency of the head frame , An elastic washer will be added in the middle during assembly, this elastic washer can give full play to the static friction effect between the outer wall of the head frame and the inner side of the slide frame, and restrain the rotation of the head frame. [0003] However, in the actual assembly process, there is still a certain gap between the outer wall of the head frame and the inner side of the slide frame. When the bolts, nuts and elastic washers are connected an...

AI Technical Summary

Problems solved by technology

When the bolts, nuts and elastic washers are connected and tightened, the carriage will be deformed under the tension of the bolts, so that the centerlines of the four shafts of the carriage deviate from the original track, resulting in a gap between the eight pulleys and the guide rail. The clearance is inconsistent, and the clearance between the pulley and the guide rail is too small to directly affect the normal operation of the head frame and the slide frame, so it is necessary to improve the assembly process of the head frame and the slide frame
