Description
Technical field
The present invention relates to a kind of numerically controlled lathe accessory, the double X-axis of specifically a kind of numerically controlled lathe are rebored slide saddle member.
Background technology
With the fast development of modern mechanical manufacturing industry, industry-by-industry, especially engineering machinery and Aero-Space industry pair
Macrotype axes series parts are in numerically controlled lathe（Hereinafter referred to as lathe）On boring deep hole machining propose requirements at the higher level：
1st, it is raising machining accuracy, it is desirable to which boring of deep hole is in place, it is to avoid the secondary clamping error that workpiece u-turn brings；
2nd, try one's best and processed with many sequences such as boring deep hole, the turnings of clamped one time completion workpiece on a machine tool, ensureing
While processing efficiency, it is ensured that hole and cylindrical axiality；
3rd, to improve efficiency, the requirement that cutting-in and cutting feed are processed in boring is increasingly improved.
Existing numerically controlled lathe, using in indexable knife tower（Hereinafter referred to as knife tower）It is upper to assemble lathe tool and boring bar simultaneously to expire
Sufficient requirements above, but it is apparent the drawbacks of this kind of scheme：On the one hand, as the depth in boring hole is increased, the length of required boring bar
Degree increases therewith, under the basic norm for meeting boring bar draw ratio, it is desirable to which boring bar diameter is also increased therewith；On the other hand, lathe
The size of boring cutter bar mounting seat is directly restricted by knife tower size and thickness on knife tower, and the often specification determination of knife tower, it is impossible to plus
Greatly.This just brings the contradiction between big boring bar diameter and the demand and limited Installing machine tool ability of clamping length increasing, system
The increasing of boring bar length and clamping length about on lathe, this just brings following unfavorable to the boring deep hole machining on lathe：
1st, boring bar length limited, if workpiece needs the deeper blind hole of boring, cannot process；
2nd, boring bar length limited, if workpiece needs boring compared with deep via, it is meant that workpiece can not possibly clamped one time machine, only
Be able to cannot be ensured using the method for u-turn processing, workpiece accuracy；
3rd, it is installed on knife tower including all cutters including various lathe tools, drill bit, screw tap, boring bar, is interfered with each other, is limited
The workpiece adaptability of lathe processed；Especially boring bar long, it is more long that it takes Z axis stroke, operate it is careless slightly, easily with main spindle box,
Between protection, the interference such as workpiece, because boring bar long is often prohibitively expensive, once colliding, will bring about great losses；
4th, because boring bar diameter and clamping length are limited, when overhanging more long, often vibration resistance is greatly reduced, to prevent shaking
Knife, existing way is to reduce cutting-in and cutting feed, therefore processing efficiency is extremely low.
Present invention design has been invented a kind of double X-axis of numerically controlled lathe and has been rebored slide saddle member, thoroughly solves problem above.
The content of the invention
The technical problems to be solved by the invention are, in view of the shortcomings of the prior art, there is provided a kind of double X-axis weights of numerically controlled lathe
Boring slide saddle member, it uses modularized design, and reliability simple for structure is easy to operation, traditional numeric-control lathe tool tower is being fully retained
While function, numerically controlled lathe deep hole heavy duty boring performance, machining accuracy, processing efficiency and the range of work can be greatly improved.
The present invention solve the technical scheme that is used of above-mentioned technical problem for：The double X-axis of numerically controlled lathe are rebored slide saddle member, bag
