A kind of carving mills machine
The utility model relates to a kind of Computerized Numerical Control processing technology, relates in particular to a kind of carving and mills machine.
It is a kind of of Digit Control Machine Tool that carving mills machine.It is generally acknowledged that carving mills the CNC milling machine that machine is to use little cutter, high-power and high-speed main spindle motor.The advantage of engraving machine is at carving, and is unable to do what one wishes if the rapidoprint hardness ratio more also can seem.The appearance that carving mills machine be we can say and filled up Lee's blank between the two.Carving mills machine both can be carved, but also milling is a kind of efficient high-precision Digit Control Machine Tool.
In recent years, in the Mould Machining industry, people are exploring a kind of more perfect processing mode always and are replacing traditional Electric Discharge Machining mode, to produce the profile microfissure after avoiding surface of the work because of electric machining.Owing to the be processed with advantage of Electric Discharge Machining for dark die cavity, deep trouth narrow slit, but there are certain difficulty in fine complex-shaped surface mould, decorative pattern or pattern die cavity and the big isostructural processing of profile best bright finish, its processing technology is more simultaneously, the time is longer.And the high-speed milling mode has very big advantage in the processing to these moulds, simultaneously, is accompanied by the development that can process the high hardness material cutting-tool engineering, and the application of high-speed numeric control milling machine in Mould Machining more and more widely; Along with the raising of mould industry to the finished surface requirement, require tool radius more and more littler, so having appearred in the high-speed milling Mould Machining, another kind of processing equipment one carving mills machine.It not only has the high efficiency brute force and rough mills half finish-milling working ability, has the meticulous engraving function of high suface processing quality simultaneously, makes high efficiency and excellent surface quality be able to organic unity.At present, existing numerical controlled engraving and milling device all is that the fixed-beam carving mills machine, because the restriction of fixed-beam structure, the size of its clamping workpiece can not be too big, stroke is less relatively, in addition, the overall structure of the lathe of fixed-beam structure is also bigger, and lathe bed and workbench are split type, both process respectively, adopt afterwards bolt with stationary table on lathe bed, certainly exist alignment error between the two, influenced the machining accuracy of lathe.
The utility model content
The utility model corrects at above-mentioned problems, the numerical controlled engraving and milling device that provides a kind of can clamping big workpiece, stroke suitably to increase, and the overall structure of this lathe is light and handy, machining accuracy is higher.
Concrete technical scheme is:
A kind of carving mills machine, it comprises lathe bed, workbench, left and right pillar, crossbeam, connecting plate, slide plate and numerical control unit, described workbench is located on the described lathe bed, described left and right pillar is located at the both sides of described lathe bed respectively, be located on the left and right pillar and along the moving described crossbeam of y-axis shift and drive by drive unit, the described connecting plate that moves along X-axis is located on the described crossbeam, is located on the described connecting plate along the described slide plate of Z axle feeding, and described numerical control unit is connected respectively with each parts.The utility model adopts gantry vertical structure, can the big workpiece of clamping, and stroke also suitably increases.Lathe bed and workbench one, good rigidly not only, and do not have alignment error between the two, the long-time use can not influence machining accuracy yet; The X-axis guide rail cross section of crossbeam has the inclination angle of 30 degree, the corresponding machining accuracy that improved; Crossbeam adopts the single-ended drive device, has reduced cost satisfying on the basis of instructions for use.
It also comprises dismountable assembly parts, and described assembly parts comprise cutterhead supporting rod and cutterhead, and described cutterhead supporting rod one end is installed on the described crossbeam, and the other end is installed cutterhead, and milling cutter can be installed on main shaft or the cutterhead.The utility model is by being provided with cutterhead supporting rod and cutterhead at crossbeam, make its carving mill the function more the machine function is used, both can have been realized boring carving, also can realize carving the function of milling, and the control function is simple, operability is relatively good, the utility model can carry out trickle processing, and machining accuracy is higher.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram.
The specific embodiment
Describe the utility model by the following examples, should be noted that, cited embodiment should not understand the restriction to utility model.
As shown in the figure: a kind of numerical controlled engraving and milling device of present embodiment, it comprises lathe bed 1, workbench 2, left and right pillar 3, crossbeam 4, connecting plate 5, slide plate 6 and the numerical control unit that is used to control lathe work, workbench 2 is located on the lathe bed 1, both are cast into an integral body, left and right pillar 3 is located at the both sides of lathe bed 1 respectively, the crossbeam 4 that moves along the V axle is located on the left and right pillar 3 and by drive unit and drives, and X-axis guide rail 7 cross sections of crossbeam 4 have the inclination angles of 30 degree; This drive unit is the single-ended drive device, and it comprises servomotor 8, ball-screw 10 and diaphragm yielding coupling 9, and servomotor 8 and ball-screw 10 are located on the right column 3, and servomotor 8 is connected by diaphragm yielding coupling 9 with ball-screw 10.The connecting plate 5 that moves along X-axis is located on the crossbeam 4, is located on the connecting plate 5 along the slide plate 6 of 2 feedings; Numerical control unit comprises display 12 and the electric cabinet 11 of numerical control device is housed that it is connected with each parts respectively by circuit.
Machine adopted gantry vertical spindle structure of present embodiment, the direct connection transmission, simple in structure, the frame structure sealing.Main shaft adopts electric main shaft, and adopts the frequency conversion infinitely variable speeds, and rotating speed maximum speed scope is in 2000～18000 seals 111, and the carving that can be used for moderate duty mills processing.The V axle moves and adopts servomotor 8 to add ball-screw 10 drivings, belongs to the control of semiclosed loop form, can reach degree of precision.Accurate rolling guide-rail pairs and precise ball screw pair are adopted in lathe X, V, the motion of Z three-dimensional, all guide rail screw mandrels all adopt oil pump centralized lubrication form, guaranteeing that oil pump has under the prerequisite of enough lubricating oil, must any maintenance work can use, not wear and tear hardly for a long time.The transmission of X, V, Z three-dimensional adopts accurate diaphragm yielding coupling directly to connect with servomotor, flexible movements, fluent creeping, no backlass.
Obviously; foregoing is just in order to illustrate characteristics of the present utility model; and be not to restriction of the present utility model, the variation that the those of ordinary skill in relevant technologies field is made in the corresponding techniques field according to the utility model should belong to protection category of the present utility model.
