A flexible production line and processing method for axle box processing

Abstract

The invention provides a flexible production line for axle box body machining. The production line comprises a tool setting gauge, a control system, a linear tray system, a plurality of machining centers, a feeding station and a discharging station. Operation tables are distributed on the same side; the linear tray system comprises a machine tool and a plurality of trays; an axle box body can be fixed to the top of each tray; the bottom of each tray is detachably fixed to the machine tool; each tray can correspond to any one of the machining centers; and the control system can control all the machining centers to separately conduct numerical control machining on the axle box bodies on the trays. The invention further provides a flexible production line machining method for axle body machining. According to the flexible production line for axle box bodies and the machining method, multiple machines can be controlled by one person, the production efficiency is improved, and the product quality is ensured.

Description

Technical field [0001] The invention relates to a flexible production line, in particular to a flexible production line used for axle box body processing and a processing method using the production line for axle box body processing. Background technique [0002] Railway vehicle axle boxes are divided into left and right parts, and each axle box body is processed in multiple steps. At least 4 tooling stations (2 equipment) are required for each axle box body, but in general, parallel production of EMUs There are more than a dozen varieties of axle box bodies, such as, intercity cars, large railways, and subways. Therefore, the axle box body processing tooling needs to be disassembled and reinstalled many times. Multiple disassembly and assembly affect the accuracy of the tooling. The axle box body has high-precision machining requirements. The positioning accuracy needs to be guaranteed; each disassembly and assembly needs to re-detect, find the machine rotation center and reset ...

Problems solved by technology

[0002] The railway vehicle axle box is divided into left and right parts, and each axle box is processed in multiple steps. Each axle box requires at least 4 tooling stations (2 sets of equipment), but generally speaking, the EMUs are produced in parallel. , intercity vehicles, large railways, subways and more than a dozen varieties of axle boxes, so the axle box processing tooling needs to be disassembled and reinstalled many times, and the multiple disassembly and assembly will affect the accuracy of the tooling. The axle box has high-precision processing requirements, and the tooling The positioning accuracy needs to be guaranteed; every disassembly and assembly needs to be re-inspected, searched for the rotation center of the machine tool and reset the coordinate origin, which requires a long auxiliary time

The original processing method of the axle box has casting defects exposed after rough machining, which needs to be repaired by welding and sent back to the rough manufacturer for repair and then returned to reprocessing
