Special tool for milling and processing K2 side bearing axial trough

Abstract

The invention discloses a special tool for milling and processing a K2 side bearing axial trough and belongs to the technical field of a mechanical processing tool. The tool comprises a recessed base of which the upper surface is provided with an opening, an upper tapered wedge and a lower tapered wedge are arranged in the base, two slopes of the upper tapered wedge and the lower tapered wedge are matched, left sides and right sides of the upper tapered wedge and the lower tapered wedge are matched with the inner surface of the vertical end plate of the base, a pressing plate and an upper limiting mechanism which limits the motion of the pressing plate are arranged on the upper portion of the upper tapered wedge, and the side of the lower tapered wedge is connected to a piston rod of a cylinder, which is arranged on the outer wall of the base. During the process of the K2 side bearing, the detection and classification process of the trough vertical face is omitted, the processing efficiency is improved, the assisting time is saved, the labor intensity is reduced, the efficacy is improved, and the processing quality is guaranteed.

Description

technical field [0001] The invention relates to the field of processing equipment for truck accessories. Background technique [0002] With the continuous development and progress of the social economy, the number of railway vehicles is increasing, and the quality of locomotive manufacturing is also getting higher and higher. In the accessories of railway vehicles, the side bearings on the truck bogie are its important parts. The side bearings are arranged at both ends of the beam perpendicular to the running direction of the vehicle, close to the wheels, and its function is to buffer the pressure on the beam caused by the tilting of the carriage to the outside when the vehicle turns. After 5 years of use on the truck, the key parts of the shaft groove were worn out, and the size was out of tolerance. After the second welding repair, it was reprocessed. Before machining the existing side bearings, each workpiece must be inspected and classified. After machining, it is nece...

AI Technical Summary

Problems solved by technology

The worktable is frequently lifted and lowered during processing, and the process is cumbersome; coupled with manual pressing, the labor intensity is high, the production efficiency is low, and the dimensional accuracy is difficult to guarantee

During the production process of the side bearing, due to the many processing procedures and the lack of special fixtures, it can only be processed in a single piece, and each time it needs to be fixed manually, aligning and correcting the position, size, etc., resulting in poor manufacturability of the side bearing processing , long production cycle, low processing efficiency, resulting in waste of manpower and material resources
