Background technology

Along with the fast development of Digit Control Machine Tool, the numerous and confused Digit Control Machine Tool product of releasing separately of each lathe producer, Digit Control Machine Tool process technology has become some efficient, high accurately machined main modes of production at present.But during with general NC machine tooling, general employing pawl is fixed one and is brought in the cutting other end and its inner chamber, if just must use center rest support compared with machining long workpieces, otherwise cannot accomplish rigidity cutting, good numerically controlled lathe does not reach cutting precision, earthquake-resistant condition yet more with this understanding, so quality is repaiied system by follow-up craft completely, product percent of pass is low, interchangeability is poor, and cutter loss is quite large, and the other end process change need to tune face processing.Working (machining) efficiency is very low.

The utility model has overcome the shortcoming being showed with upper type structure at all, by simple and effective structure, arranges, and increases cutting rigidity, reduces the step of clamping mould and production, has improved operating efficiency.

Summary of the invention

The technical solution that realizes above-mentioned purpose is: a kind of Double End structure of numerically controlled machine-tool, comprising being arranged in machine tool main body middle part, for the Double End main shaft of holding workpiece, the vertical lathe base of this Double End main shaft is installed, parallel to the ground, wherein the both sides in this Double End spindle hole are all furnished with the chuck for clamping work pieces, and two end faces that make to be positioned at the workpiece in this Double End main shaft chamber stretch out from the both sides of Double End main shaft simultaneously; This Double End main shaft is driven by the power motor that is positioned at its underpart, drives the workpiece in this Double End main shaft chamber to rotate together with this Double End main shaft; The left and right sides of facing this Double End main shaft respectively has a set of cross slid platform, and the left and right knife rest of automatic tool changer is installed on this cross slid platform, and this left and right knife rest can be processed stretching out the workpiece at these Double End main shaft two ends under the driving of X-axis motor and Z axis motor simultaneously.

Wherein this Digit Control Machine Tool adopts inclined 45 degree, two kinds of machine tool structures of vertical 90 degree.

Wherein the through-hole diameter of this Double End main shaft is preferably and is not more than 500mm.

Wherein the described chuck employing floor push of this Double End main shaft is controlled and is unclamped and clamp.

Wherein also comprise the magnetic chip cleaner being arranged in Digit Control Machine Tool.

Double End structure of numerically controlled machine-tool of the present utility model, with respect to prior art, has the following advantages:

1, can shorten the processing distance of two fulcrums, increase cutting rigidity;

2, can remove the jockey of two-half die;

3, improve clamping and working (machining) efficiency, two end face clamped one times complete whole processing.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in accompanying drawing 1-3, Double End structure of numerically controlled machine-tool of the present utility model, comprising being arranged in machine tool main body 1 middle part, for the Double End main shaft 2 of holding workpiece, the vertical lathe base of this Double End main shaft 2 is installed, parallel to the ground; Both sides in these Double End main shaft 2 holes are all furnished with the chuck for clamping work pieces, and two end faces that make to be positioned at the workpiece in these Double End main shaft 2 chambeies stretch out from the both sides of Double End main shaft 2 simultaneously; This Double End main shaft 2 is driven by the power motor 3 that is positioned at its underpart, drives the workpiece in these Double End main shaft 2 chambeies to rotate together with this Double End main shaft 2; The left and right sides of facing this Double End main shaft 2 respectively has a set of cross slid platform 4, the left and right knife rest 5 of automatic tool changer is installed on this cross slid platform 4, and this left and right knife rest 5 can be processed stretching out the workpiece at these Double End main shaft 2 two ends under the driving of X-axis motor 6 and Z axis motor 7 simultaneously.

Double End structure of numerically controlled machine-tool of the present utility model has adopted inclined 45 degree, two kinds of machine tool structures of vertical 90 degree, and the knife rest at two ends can carry out endoporus, cylindrical, end face to this part and cut simultaneously, thereby reached problem to be solved in the utility model.The through-hole diameter of the Double End main shaft 2 of Double-blade structure of numerically controlled machine-tool of the present utility model is preferably and is not more than 500mm; The described chuck employing floor push of Double End main shaft 2 is controlled and is unclamped and clamp; Also comprise the magnetic chip cleaner being arranged in Digit Control Machine Tool.

Structure of the present utility model has fully demonstrated its performance and the problem that should solve, after protective door is opened, workpiece is put into and is positioned at the middle main shaft chamber of lathe, and now the chuck clamping work pieces of inner chamber is located and controlled with floor push to workpiece, makes part be fixed on main shaft inner chamber.Main shaft rotates thereupon under the main Electric Machine Control of lower end, and produce the rotating speed of 0--4500 rev/min, the knife rest at two ends moves to rapidly two end faces of this main shaft under the control of digital control system according to program thereupon, cut simultaneously, and tool changing completes appointment requirement continuously, scrap has also taken in litter-bin by chip cleaner.
