Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] The automatic production line for rail vehicle door frame welding and milling of the present invention has a high degree of automation in welding and milling, and has an automatic welding seam tracking unit, an automatic milling compensation unit and an online automatic detection unit, and solves the problem of welding by quickly changing fixtures and processing processes. The weld seam precision of the production line is poor. The problem of unreliable welding quality, and integrate the welding and milling processes on the same production line, further promote the automation process, such as figure 1 and figure 2 As shown, the automatic production line for rail vehicle door frame welding and milling includes a work platform 8, on which a three-axis numerical control positioner 1, a door frame pneumatic clamp unit 2, a tool buffer table 3, and a manual grindi...

Abstract

The invention discloses an automatic production line and method used for welding and milling a door frame of a railway vehicle. The automatic production line comprises a working platform, the working platform is provided with a triaxial numerical control positioner, a door frame pneumatic clamping unit, a tool caching table, a manual polishing region, a quality automatic detection unit, a product automatic sorting unit, a first door frame storage table, a first robot, a second door frame storage table, a welder and a second robot; the door frame pneumatic clamping unit is divided into two groups, each group is arranged on the triaxial numerical control positioner, the two groups of the door frame pneumatic clamping unit are controlled by the triaxial numerical control positioner to overturn, and each door frame pneumatic clamping unit is used for fixing a to-be-processed door frame. The automation degree of the welding and the milling is high, a gap welding automatic tracking unit, a milling automatic compensation unit and an online automatic detection unit are obtained, the problems that gap welding of a welding production line is poor and the welding quality is not reliable are solved, the procedures of welding and milling are completed on the same production line, and a good application prospect is obtained.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to an automatic production line and method for welding and milling rail vehicle door frames. Background technique [0002] At present, welding robots or milling robots can improve the efficiency and quality of rail vehicle door frame welding or milling production lines, and improve working conditions, so they have been widely used. However, the production line of welding robots is difficult to ensure the accuracy of welds, and the production line of milling robots is difficult to ensure the accuracy of milling, resulting in low reliability of welding and milling quality. Moreover, at present, the two processes of welding and milling are in different production lines It is carried out on the ground, and the degree of automation is low, which needs to be further improved. Contents of the invention [0003] The technical problem solved by the invention is that the reliability...
