Abstract
The invention discloses a double-head milling machine. The main mechanical structure of the double-head milling machine comprises a supporting seat, a portal frame, a C-shaped frame, spindle head components, a tray, a tray supporting seat and a portal supporting seat. The supporting seat is fixed to the ground through ground screws. A guide rail and a rolling body are arranged between the tray supporting seat and the supporting seat to achieve rolling friction. In work, the tray is fastened and fixed through the tray supporting seat and the tray and a part to be machined are driven to be dragged by a motor to move in the X direction. The C-shaped frame is dragged by the motor to move relative to the portal frame, so that a machine tool moves in the Y direction. The spindle head components are dragged by the motor to move relative to the C-shaped frame, so that the machine tool moves in the Z direction. Two spindle heads are mechanically fixed through the C-shaped frame and kept on the same axis all the time. The double-head milling machine is simple in structure and the two faces of the part can be machined at the same time; and in the machining process, spindles at the two ends can make contact with the part all the time to support each other, and part deformation is reduced.
Description
Technical field
The present invention relates to CNC milling machine, particularly duplex head milling machine, belong to the machine tool field of metal cutting process equipment, be mainly applicable to the processing of typical aircraft structure as frame and beam etc.
Background technology
In recent years, along with Chinese national economy develops rapidly, wilderness demand is proposed to Digit Control Machine Tool.Typical aerospace component needs two-sided processing as frame and beam etc., needs turn-over Set and Positioning repeatedly, causes mismachining tolerance, affect the precision of part in process.Two-sided processing clamped one time location can improve the working (machining) efficiency of this kind of part greatly.At present, there is the lathe of various structures form, had five-axis linkage machine tools, New Type Parallel Machine Tool, multiple main axle machine tool, the Digit Control Machine Tool of two-sided processing can have been realized.But the domestic Digit Control Machine Tool that can not carry out two-sided processing to aerospace component at present.Patent CN2799136Y proposes a kind of Dual-headed machine, frame for movement is by two lathe combination public lathe beds, a base, two main shafts realize two-sided processing relatively.Machine tool structure does not roughly have anything to change.Patent CN102615315A proposes a kind of automatic double-head milling machine, can realize two-sided processing, but main or a set of double end milling blanking equipment.
Summary of the invention
The present invention relates to a kind of duplex head milling machine, can process part two sides simultaneously.
Technical scheme of the present invention is as follows:
A kind of duplex head milling machine, comprise supporting seat, tray support seat, portal frame and pallet, supporting seat is fixed on ground by fot screw, tray support seat is installed on supporting seat, guide rail is provided with between tray support seat and supporting seat, pallet is installed on tray support seat, the X-direction that tray support seat can drive pallet to make lathe along guide rail is moved, portal frame is installed on ground, portal frame is provided with C type frame, pallet is positioned at the opening of C type frame, and the two ends that C type frame opening is relative are respectively arranged with the main tapping of milling machine, and two main tappings keep on the same axis.
The C type frame of a kind of duplex head milling machine of the present invention can do moving of vertical direction along portal frame, forms the Y-direction motion of lathe.
The main tapping parts of a kind of duplex head milling machine of the present invention under motor drag effect with the relative motion of C type frame, realize the Z-direction motion of lathe.
The portal frame of a kind of duplex head milling machine of the present invention is installed and ground by gantry bracing frame, is provided with on guide rail between portal frame and gantry bracing frame 7, and portal frame can move along gantry bracing frame, realizes the motion of lathe X-direction.
The present invention compared with prior art tool has the following advantages:
1, structure is simple, can realize two-sided processing, raise the efficiency;
2, in process, two ends main shaft can contact part all the time, supports mutually, reduces part deformation;
3, adopt suitable digital control system to control can realize cutting line by line, improve the establishment efficiency of procedure greatly.
Accompanying drawing explanation
Fig. 1 is structural representation sketch of the present invention.
Fig. 2 is for having the moveable structural representation sketch of the present invention of portal frame.
Specific embodiments
Below in conjunction with accompanying drawing, the invention will be further described
See Fig. 1, the first structure of the present invention, supporting seat 1 is fixed on ground by fot screw, guide rail and rolling element is had to realize rolling friction between tray support seat 6 and supporting seat 1, during work, pallet adds and fastens by tray support seat, and under motor drag, realizes X-direction motion with pallet 5 and part to be processed.C type frame 3 under motor drag with portal frame 2 relative motion, formed lathe Y-direction motion.Main tapping parts 4 under motor drag effect with C type frame 3 relative motion, realize lathe Z-direction motion.The feature of the technical program is that two main tappings 4 remain on the same axis under the machinery of C type frame is fixing
See Fig. 2, the second structure of the present invention, supporting seat 1 is fixed on ground by fot screw, has guide rail and rolling element to realize rolling friction between tray support seat 6 and supporting seat 1, during work, pallet adds and fastens by tray support seat, and part to be processed fixed by pallet 5.Whole C type frame 3, portal frame 2 etc. can move under motor drag on gantry bracing frame 7, realize the motion of lathe X-direction.C type frame 3 under motor drag with portal frame 2 relative motion, formed lathe Y-direction motion.Main tapping parts 4 under motor drag effect with C type frame 3 relative motion, realize lathe Z-direction motion.Two main tappings 4 remain on the same axis under the machinery of C type frame 3 is fixing.
