Description
(1) technical field
The utility model relates to a kind of digital control plane milling and boring machine.Be mainly used in processing such as reduction box box parts.Belong to the metalworking machine tool field.
(2) background technology
The reduction box box parts is very high to the processing request in hole, the size tolerance requirements height in hole not only, requirement to the form and position tolerance in hole is also very high, the depth of parallelism of the axiality in two holes of particularly same axis, the axis of adjacent holes must meet the requirements, otherwise the load that can influence on the gear distributes, light unbalance loading then, heavy then broken teeth.The work flow of this class part generally is: on roughing plane on the milling machine---at rough bore on the boring machine---at precision-machined surface on the milling machine---right boring hole on boring machine.Severally so just can process back and forth, this processing method production efficiency is very low, and the product precision is not high yet.
Present digital control plane milling and boring machine mainly contains two kinds of forms as depicted in figs. 1 and 2.The digital control plane milling and boring machine of these two kinds of forms, plane and hole that generally can only the process water plane.With the boring and milling head outer of special use, also can process the plane and the hole of inclined plane, vertical plane.But because the boring and milling head outer cantilever is settled, easily produce tapering during the boring deep hole, need respectively from the two sides boring during through hole of boring casing two sides, the axiality in hole is not high, can not satisfy the needs to casing processing that improve day by day.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, the high high rigidity digital control plane milling and boring machine of axiality in hole when the through hole of a kind of boring casing two sides is provided.
The purpose of this utility model is achieved in that a kind of high rigidity digital control plane milling and boring machine, comprise built-in beam movable workbench formula CNC planer type milling machine, this built-in beam movable workbench formula CNC planer type milling machine comprises lathe bed, workbench, column and crossbeam, on described built-in beam movable workbench formula CNC planer type milling machine, have additional the boring head and a boring bar of a horizontal setting, boring head comprises the boring head delivering gear, boring bar is installed on the boring head, on two root posts of described built-in beam movable workbench formula CNC planer type milling machine, have additional a vertical guide rail respectively, be connected with one respectively on described two vertical guide rails and move horizontally guide rail, the bushing bearing of described boring head and boring bar is installed in described two respectively and moves horizontally on the guide rail, and described two move horizontally guide rail and all link to each other with a synchronous elevating mechanism.
The beneficial effects of the utility model are:
The utility model increases the boring head and the high rigidity boring bar of horizontal setting by on the basis of built-in beam movable workbench formula numerical control gantry mill, adopts the interlock of vertical guide rail and feed screw nut, thereby realizes moving up and down.Boring bar has very high rigidity.The screw mandrel that drives boring head and boring bar adopts control digital control and workbench to join together, and can obtain the positioning accuracy in higher hole.Boring head can move laterally along horizontal guide rail, and the boring cutter that drives on the boring bar is done to finish the machining in hole along the feed motion of the axis in hole, and the horizontal movement of boring head is also adopted digital control.Because boring bar is a relatively independent member, therefore can manufacture and design separately according to the size in hole, to guarantee enough rigidity, satisfy the needs of hole processing.On a machine tool, can solve the processing in the plane and the hole of end face and side like this, and because the high rigidity of boring bar, the cylindricity in hole and axiality have also reached pre-provisioning request.
