Description

Front door hat brim welding workstation for carriage production

Technical Field

The invention relates to the technical field of carriage processing, in particular to a front door hat brim welding workstation for carriage production.

Background

The carriage body is usually made of gray cast iron, and the gray cast iron has good casting performance and vibration damping performance. For heavy load or impact load, the spindle box of the middle planer milling machine can also adopt a cast steel carriage body as a speed reducer of the carriage body load. In order to simplify the process and reduce the cost, the speed reducer produced by a single piece can adopt a box body welded by steel plates. In order to facilitate the installation and the disassembly of the shafting components, the carriage body is made into a horizontal split type along the axis. The upper box cover and the lower box body are connected into a whole through bolts. The connecting bolts of the bearing seat should be as close to the bearing seat holes as possible, and the bosses beside the bearing seat should have enough bearing surfaces to place the connecting bolts and ensure the spanner space required when screwing the bolts. In order to ensure that the carriage body has enough rigidity, a supporting rib is added near the bearing hole. In order to ensure the stability of the arrangement of the speed reducer on the foundation and to reduce the machining area of the carriage base plane as much as possible, the carriage base does not generally adopt a complete plane. When the carriage body is processed, the carriage body is welded with the front door hat brim, and the front door hat brim for carriage body production belongs to an essential procedure in the carriage body processing process.

The welding of the front door hat brim of the existing carriage body production generally adopts semi-automatic welding, the processing efficiency of the front door hat brim of the carriage body is lower, the clamping alignment effect of the front door hat brim product in the welding process is poorer, the accuracy of the front door hat brim during welding is lower, and the yield is lower.
