Abstract

The utility model provides a numerical control lathe for machining special shaped cylinders, which belongs to the field of machining equipment manufacture. The lathe consists of a lathe body, a lathe head, lathe legs, a controller, a main shaft, a tailstock, an encoder, a Z axis screw rod, a Z axis driving motor, a carriage, an X axis motor, an electric tool rest and an electric tool rest motor. The lathe is characterized in that the lathe is also provided with a rotary tool rest; the rotary tool rest is arranged on the carriage where the electric tool rest is, and is driven by a rotary tool rest motor; the advance and retreat of the rotary tool rest is driven by the X axis motor and an X axis screw rod arranged under the carriage; and a plurality of tools are uniformly distributed and arranged on the rotary tool rest. The controller sends out control signals in real time according to a precompiled program and drives every component through the driving motor, and then the lathe can machine cylinder workpieces in the shape of a regular polygon, a helix, a circle, a cone, a square cone and other special shapes. The lathe has the advantages of simple structure, convenient control, simple operation, high machining precision, high speed and wide adaptability.

Description

A kind of numerically controlled lathe of working special-shaped cylinder

Technical field

The utility model relates to a kind of machining equipment, exactly is a kind of numerically controlled lathe, more precisely a kind of numerically controlled lathe of working special-shaped cylinder.

Background technology

Lathe generally is used for the processing column body, the general milling machine that adopts when needs processing polygon cylinder, one side is processing simultaneously, processing is not only slow like this, and machining accuracy is not easy to guarantee, the patent No. is that the Chinese patent " a kind of polygon bar lathe for machining " of 200420038951X provides a kind of lathe of processing the polygon bar, its technical characterictic is to be provided with the polygon bar to clamp mold and a rotation milling head on lathe, can improve process velocity and precision like this, but it remains by milling processing in essence, and not numerical control, process velocity and precision are not high, particularly it can only process polygonal bar, running into polygon just can't process with circular alternate product, therefore, a kind of numerically controlled lathe that can working special-shaped cylinder of design is that mechanical processing industry is badly in need of a technical barrier solving.

Summary of the invention

The purpose of this utility model provides a kind of numerically controlled lathe of working special-shaped cylinder, require to have simple in structure, control is convenient, easy and simple to handle, machining accuracy is high, speed is fast, the advantage of wide adaptability.

The purpose of this utility model is realized by following technical scheme.

The numerically controlled lathe of a kind of working special-shaped cylinder of the utility model, by lathe bed, the lathe head, the lathe pin, controller, main shaft, tailstock, encoder, Z axial filament thick stick, the Z axis drive motor, planker, the X-axis motor, electric driving tool post, the electric driving tool post motor is formed, these parts have been formed the logical numerically controlled lathe of a Daepori, controller is according to the program of compiling and editing in advance, the main shaft that control is corresponding, the motion of planker and knife rest, part that can the processing column body, numerically controlled lathe at a kind of working special-shaped cylinder of the present invention, it is characterized in that swivelling tool-holder in addition, swivelling tool-holder is installed on the planker at electric driving tool post place, by the swivelling tool-holder motor-driven, its advance and retreat are then driven by X-axis motor and the X-axis screw mandrel that is installed in below the planker, and knives is installed on the swivelling tool-holder evenly distributedly.Each parts provides control signal by controller in real time according to the program of working out in advance and drives by drive motors, add man-hour, workpiece is under the situation of rotating at a high speed on the main shaft, electric driving tool post is selected suitable cutter automatically, controller provides the suitable amount of feeding of signal controlling and translational speed is cut workpiece, at this simultaneously, controller is according to the rotary speed and the zero signal of main shaft, correspondingly control the rotary speed of swivelling tool-holder and the synchronously point of penetration and the amount of feeding, thereby obtain satisfactory machining locus according to the control parameter that the successional Mathematical Modeling of the tangential point orbit of two revolutions provides adaptation.What be worth emphasizing is: in order to adapt to machinery and the response speed of control and the requirement that meets the fineness of finished surface, this device adopts main shaft and the rotation of swivelling tool-holder rightabout, with the relative cutting speed of raising cutter and workpiece.Special-shaped cylinder workpiece such as after being the motion control process of example by one, that lathe can process is just polygonal, screw type, round, pyramid type, side are tapered.

In the numerically controlled lathe of a kind of working special-shaped cylinder of the utility model, its basis is the logical numerically controlled lathe of a Daepori, a swivelling tool-holder is installed on planker again, structure is also uncomplicated, be chosen in according to the characteristics of processing parts knives is installed on the swivelling tool-holder, such as processing 3 bodies, can on knife rest, install 3 cutter or 6 cutter, process 4 bodies 4 cuttves can be installed, design control program then and control main shaft, planker, electric driving tool post, parameters such as the rotary speed of swivelling tool-holder and the depth of cut, just can process different workpiece, compare with original technology, the transmission of each parts of system relies on and flexibly connects, machining accuracy and flexibility have been improved to essence, can rapid processing go out the changeable cylinder of shape, therefore, the utlity model has simple in structure, control is convenient, easy and simple to handle, the machining accuracy height, speed is fast, the advantage of wide adaptability.
