At present, in order to ensure the workpiece in a clamping, machining multiple surface and at the same time as far as possible more surface, improve the machining efficiency, reduce the auxiliary time processing, ensure the machine of the same function and the processing scope of cases, make the machine area as small as possible, in order to solve this problem, machine tool manufacturers have adopted vertical machining center machine tool, it is composed of base, ram, a table, column, spindle box and is used to control the CNC machine tool CNC units of each parts work base top ram and pillar, the lower ram upon the bed base sliding connection with the slippery course of rain, and the base is equipped with the screw drive along the Z axis horizontal slide, The working table is connected with the sliding pillow by the sliding rail on the upper part of the sliding pillow.
And the slippery pillow with lead screw drive along the X axis horizontal slide, pillar side is equipped with guide rail, a spindle box on the guide rail, the spindle box on the pillar is equipped with the screw drive up and down along the guide rail vertical sliding, spindle box under the workbench with spindle head straight, the spindle box top is equipped with servo motor, driven by servo motor spindle head spin, and parts for processing, its defect is: in the process of machining, the need to repeatedly change state of positioning of workpiece on the workbench, and machining of extension of time, low production efficiency, increase the labor intensity of workers; Some use of five-axis linkage machining center machine tool, it is composed of base, columns, a table, rotary table, lift leadscrew, headstock, and is used to control the CNC units CNC machine parts, the base is equipped with worktable, end a pillar, the base of the mast horizontal slide has used to drive screw, workbench upper is equipped with rotary table, which can realize the workpiece along the Z axis rotation 360 degrees, is equipped with the spindle box on the column, spindle box on the pillar is equipped with the screw driver can slip up and down the column on the guide rail, spindle box adopts cyclotron 90 degrees for spindle of rotors, realize the main shaft of the bed, In order to achieve the processing of multiple parts of the workpiece, its disadvantages are: need to change the spindle rotating body position to process multiple parts of the workpiece one by one, processing time is long, low production efficiency; Still have one kind is to use much mill head processing center machine tool to process many faces at the same time, and use exchange workbench device to process the workpiece, in order to reduce the processing auxiliary time, its inadequacy is: machine tool cost is high, cover an area of large.
In order to ensure the workpiece in a clamping, processing multiple surface at the same time as far as possible, the vertical and horizontal machining center machine tool machining center machine, combining the advantages of vertical milling head and horizontal milling and processing the same workpiece at the same time, a processing five when the clamping surface, a kind of novel structure, convenient operation, reduce the processing time, improve production efficiency, reduce cover an area of double vertical machining center machine tool.
Includes base, pillar, drive screw, spindle box and is used to control the various parts of the CNC numerical control unit, spindle box with spindle head at one end, another end is equipped with servo motor, its characteristic is that the base is equipped with a fixed columns, columns, activity on the workbench device and the lower workbench device, the base unit is equipped with the workbench, the workbench of carriage bottom by the drive screw connected to the base, and by the drive screw driver makes the workbench device along the screw axis X, the workbench device on both sides respectively before and after the front and back bracket, left and right sides of the activity pillar and fixed columns respectively,
Before stent bottom bracket and respectively connected with the base fixed, the top of the guide rail and slide carriage of the workbench device, workbench devices on both ends of the carriage and support before and after the holder has driven screw joint, the drive screw drive, enable the workbench device glide along the X axis direction, columns and the base fixed connection, post after fixed on the base of the drive screw connected to the base, and the drive screw drive, the activity post along the drive screw axis X, activity has a horizontal spindle box on the column,
Horizontal spindle box by the fixed vertical drive screw on activities column column sliding connection with activity, and the vertical drive screw drive along the Y direction slip, equipped with vertical spindle box, fixed column vertical spindle box by fixed on the fixed column vertical drive screw with fixed column sliding connection, and the vertical drive screw drive Y direction slip, vertical machining center machine and horizontal machining center machine tool, Shared workbench upper and lower layer, reduced the area, reducing the processing auxiliary time, improve the working efficiency.
Device on the workbench and the workbench is respectively by the workbench, rotary table, turbine, worm, servo motor, carriage, drive screw and guide rail and slide block in the middle for the hollow cavity, the cavity inside along the Z axis is equipped with guide rail, guide rail top has driven screw drive screw and guide rail same direction, the lower body and guide rail sliding table, the top sides and drive screw joint, intermediate with trapezoidal groove, rotary table located within a trapezoidal groove, rotary table bottom is equipped with the turbine, the turbine by the worm and fixed on the workbench body engages the servo motor, driven by servo motor, The turbo worm drives the rotary table to rotate, and the driving screw drives the table body to slide along the Z axis, so as to facilitate the horizontal spindle milling head to carry out milling on the four surfaces of the workpiece. To achieve the vertical milling head and horizontal milling head at the same time processing the same workpiece, a clamping can be processed five surfaces, with a new structure, easy to operate, reduce processing time, improve production efficiency, reduce floor area and other advantages.
