Abstract
The utility model discloses a lathe bed structure of a double-column vertical lathe, which adopts the structure that a headstock and a tailstock are mounted on a base; a spindle is arranged vertically; a workpiece positioning clamp is mounted at the top of the spindle; a workpiece clamping component capable of moving up and down and a tailstock motor are arranged on the tailstock; the workpiece clamping component is arranged right above the workpiece positioning clamp; two upright posts on two sides of the tailstock respectively are arranged on the base; saddles are fixed on the front sides of the upright posts through vertical rails respectively; servomotors used for driving the saddles correspondingly are arranged on the upright posts respectively. The lathe bed structure has the advantages that process of changing a middle convex piston into an elliptic piston is simplified; the equipment utilization ratio and the processing efficiency are improved; improvement on the aspects such as production cost and product precision are remarkable.
Description
Technical field
The utility model relates to a kind of lathe, relates in particular to a kind of lathe bed structure of the double column vertical lathes for machining piston.
Background technology
Piston is the strength member of the internal combustion engine of various vehicles, and its crudy directly affects the performance of vehicle, and particularly the shape line precision of middle-convex and varying ellipse shape periphery is the hugest on the end product quality impact.Need to carry out the kinds of processes such as annular groove cutting, chamfering, end face turning and periphery turning in middle-bulged varying ellipse piston processing, existing lathe equipments function is comparatively single, need multiple independent equipment could meet aforesaid operations, equipment investment is large, process-cycle is long, production efficiency is low, manually reaches equipment operating cost high; And add man-hour at distinct device, need again clamp location, easily produce larger error, do not utilize the assurance machining accuracy, and affect product quality.
Summary of the invention
It is a kind of reasonable in design that the purpose of this utility model is to provide, and has the lathe bed structure of a kind of double column vertical lathes of grooving, finish turning top and Excircle machining function.
For realizing above-mentioned technical purpose, the utility model adopts following scheme: a kind of lathe bed structure of double column vertical lathes, main spindle box and tailstock are installed on base, main shaft is perpendicular to be put and top is installed on workpiece positioning clamp, liftable Work-sheet pressing assembly and tailstock motor are installed on tailstock, the Work-sheet pressing assembly be positioned at workpiece positioning clamp directly over; Base is provided with two columns that lay respectively at the tailstock both sides, and two column front sides are fixed with saddle by vertical rail respectively, are respectively equipped with the servomotor that drives corresponding saddle on column.
But be separately installed with annular groove essence top frock, the processing tool for excircle of horizontal feed on described two saddles.
Described two saddle upper ends are connected with respectively chain, and the chain other end is connected with the balancing weight of column rear side, and described column upper end is provided with chain guide wheel.
Described main shaft inner hollow, be provided with the pull bar that drives workpiece positioning clamp in chamber, the pull bar lower end is connected with cylinder.
The utlity model has following beneficial effect: because the utility model adopts above-mentioned design, it is equipped with annular groove essence top frock, processing tool for excircle, can be after once workpiece being positioned and clamping, realize continuously the operations such as fluting, finish turning top, annular groove chamfering, cylindrical turning, simplify the processing technology of middle-bulged varying ellipse piston, improve utilization rate of equipment and installations and working (machining) efficiency, and all be significantly improved at aspects such as production cost, Product Precisions.
