Abstract
The invention provides an ultra large work-site lathe, which can integrally turn the welded parts on an installation site so that the processing precision is ensured. The ultra large work-site lathe comprises a worktable and a cutter saddle structure and is characterized in that the worktable is a circular worktable concentrically mounted with a backing ring to be processed; a hollow main shaft is mounted in the centre of the worktable, and a rotary arm is connected with the outside of the hollow main shaft via a main shaft bushing; the rotary arm is mounted on the circular worktable via a sliding plate; a speed reducer is mounted on the rotary arm; the output end of the speed reducer is connected with a gear which is in engaged transmission with a pin wheel on the circular worktable; and the cutter saddle structure is mounted on the outer end part of the rotary arm.
Description
Technical field
The present invention relates to the lathe equipments technical field, be specially the ultra-large type building site lathe.
Background technology
For the turning processing of ultra-large type parts, be the backing ring of 30 meters mining equiment such as diameter, because the backing ring volume is large, be subjected to the restriction of traffic condition, it can't be transported to the erecting bed in integral body after the job shop turning completion of processing; If be transported to erecting bed assembly welding installation and carry out segmentation turning processing in job shop, it can't guarantee machining accuracy again.
Summary of the invention
For the problems referred to above, the invention provides the ultra-large type building site lathe, it can carry out whole turning processing to the part that assembly welding is good in the erecting bed, has guaranteed machining accuracy.
Its technical scheme is such, it comprises workbench and cutter frame structure, it is characterized in that: described workbench is circular table, described circular table is installed with backing ring to be processed is concentric, the center is equipped with hollow spindle, described hollow spindle outside is connected with pivoted arm by main bearing shell, described pivoted arm is installed on described circular table by slide plate, on the described pivoted arm reductor is installed, the output of described reductor is connected with gear, pin wheel engaged transmission on described gear and the described circular table, described pivoted arm outer end is equipped with described cutter frame structure.
It is further characterized in that: described circular table comprises base plate and track; Described backing ring to be processed is clamped on the described base plate and can crosses jacking mechanism and holds out against fixing; Described jacking mechanism is provided with 12, and described 12 jacking mechanisms circumferentially are evenly arranged along described circular table; Described slide plate is installed on described raceway surface; Described pin wheel is made of bearing pin circumferential along described circular table, that be evenly arranged by described gears tooth pitch; Described cutter frame structure comprises Horizontal tool-post and longitudinal tool rest, and described Horizontal tool-post car is used for processing backing ring side end face, and described longitudinal tool rest is used for the inside and outside circular surfaces of Vehicle Processing backing ring; The power supply of described reductor is accessed by the slip ring on the described hollow spindle by wire.
Ultra-large type building site lathe of the present invention, it is simple in structure, backing ring to be processed is clamped on the circular table with one heart, drive pivoted arm around the hollow spindle rotation at concentric place by the reductor on the pivoted arm, in the time of rotation be so that the cutter frame structure on the pivoted arm is finished the Vehicle Processing to the inside and outside circular surfaces of backing ring and side end face, it can carry out whole turning processing to backing ring, and working (machining) efficiency is high, guarantees machining accuracy.
