Double-head turning and boring device of stirring cylinder body

Abstract

The invention relates to the field of processing equipment, in particular to a double-head turning and boring device of a stirring cylinder body. The double-head turning and boring device comprises cutting units, longitudinal moving seat frames, a transverse moving seat frame and an electric control system. According to the double-head turning and boring device, the two sets of longitudinal movingseat frames and the two sets of the cutting units are arranged on the two sides of the transverse moving seat frame of the stirring cylinder body, and cutter disc assemblies which comprise a plurality of cutters for different working procedures are arranged on rotating assemblies and feeding assemblies in a locked mode, and the cutters can be rotated and synchronously and radially fed under the driving of the rotating assemblies and the feeding assemblies; meanwhile, the longitudinal movement of the longitudinal moving seat frames and the transverse movement of the transverse moving seat frame are utilized to synchronously realize the advancing, returning and axial feeding of the cutters; and in addition, the stirring cylinder body can be moved transversely and rapidly, and repeated machining of multiple rows of holes in the same process is completed. According to the double-head turning and boring device, the multiple different cutters can be installed once on the two sides of the stirring cylinder body synchronously to finish turning and boring machining of coaxial holes at the two ends, so that the influence of machining precision and position degree caused by accumulated errors of tool changing and tool setting multiple times is avoided, and therefore the machining precision and the machining efficiency are improved.

Description

technical field [0001] The invention relates to the field of processing equipment, in particular to a double-head turning and boring device for a stirring cylinder. Background technique [0002] The mixing cylinder is the core component of large-scale mixing equipment for producing concrete or stabilized soil. The inner hole accuracy, coaxiality and perpendicularity of the main bearing seat at both ends of the mixing cylinder installed with the mixing spindle directly determine the quality of the main bearing. Sealing and bearing life. Therefore, the processing requirements for the hole wall and end face of the inner hole of the main bearing seat at both ends are relatively high. Most of the current processing equipment and processing technology use multiple tool changes, repeated tool setting, and separate roughing and finishing. Therefore, it is inevitable to accumulate The impact of errors on accuracy and position; in addition, large mixing tanks often use double or mult...

Problems solved by technology

Therefore, the processing requirements for the hole wall and end face of the inner hole of the main bearing seat at both ends are relatively high. Most of the current processing equipment and processing technology use multiple tool changes, repeated tool setting, and separate roughing and finishing. Therefore, it is inevitable to accumulate The impact of errors on accuracy and position; in addition, large mixing tanks often use double or multiple rows of mixing spindles arranged in parallel, and there are often two or more rows of inner holes of the main bearing housings at both ends that need to be repeatedly processed in the same process , if the mixing cylinder or processing equipment is manually moved twice or more to meet repeated processing, the efficiency is low
