Description
Technical field:
The present invention relates to used ram adjustment device, especially ram boring and milling head main-shaft fore-and-post inclination automatic adjusting device on the moving beam gantry boring and milling machine of a kind of numerical control.
Background technology:
The moving beam gantry boring and milling machine of numerical control is along with the development of society arises.It is mainly used in the multistation processing of heavy parts.It mainly is made up of lathe bed, gantry, crossbeam, slip crate, main spindle box, ram boring and milling head, ram boring and milling head is installed in the slip crate, adding the man-hour ram boring and milling head both can move up and down in slip crate, can pass through motor, main spindle box transmission realization boring and milling head outer main axis rotation again, thereby finish processing part.The moving beam gantry boring and milling machine of numerical control at present is when adopting larger diameter end facing cut cutterhead processing XY plane; because lathe influence of mounting accuracy; the front and back position of main-shaft axis in the XZ plane fixed; destroy the finished surface of front cutting edge so rear knife edge takes place through regular meeting; expert's said " sweeping cutter " phenomenon just; this phenomenon directly affects the crudy of surface of the work, and reduces cutter life, can not satisfy the needs of high accuracy processing.
Summary of the invention:
For the problem that solves the moving beam gantry boring and milling machine crudy difference of existing numerical control and lack cutter life, the invention provides a kind of ram boring and milling head main-shaft fore-and-post inclination automatic adjusting device, this ram boring and milling head main-shaft fore-and-post inclination automatic adjusting device has the workpiece crudy and reaches long characteristics cutter life well.
Technical scheme of the present invention is: this ram boring and milling head main-shaft fore-and-post inclination automatic adjusting device comprises slip crate and upper end thereof 4 panels all around, end is fixedly connected with support plate respectively about slip crate, crosswise fixed is connected with 4 hydraulic jacks under the support plate, hydraulic jack is connected with 4 panels respectively, be connected with left and right sides oil pipe on the hydraulic jack, left and right sides oil pipe is connected with hydraulic jack left and right sides hydraulic cavities respectively, and left and right sides oil pipe is connected with the hydraulic system of lathe.
The present invention has following beneficial effect: this ram boring and milling head main-shaft fore-and-post inclination automatic adjusting device is structure because 4 hydraulic jacks of employing are connected with slip crate upper end 4 panels all around respectively, utilize 4 hydraulic jack move left and right of machine operation system control, change the characteristic of panel sectional dimension, change relatively-stationary mode after the existing panel adjustment into relative sliding type, thereby reach the purpose that the front and back position of automatic adjustment ram boring and milling head main-shaft axis in the XZ plane tilts, eliminate the generation of " sweeping cutter " phenomenon, the final moving beam gantry boring and milling machine machining accuracy of raising numerical control that realizes prolongs target cutter life.And improved working (machining) efficiency, provide technical guarantee for producing high quality of products.

1-slip crate among the figure, 2-panel, 3-support plate, 4-hydraulic jack, the right oil pipe of 5-, 6-left side oil pipe.
The specific embodiment:
The invention will be further described below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, this ram boring and milling head main-shaft fore-and-post inclination automatic adjusting device comprises slip crate 1 and upper end thereof 4 panels 2 all around, slip crate about 1 ends are fixedly connected with support plate 3 respectively by bolt, support plate 3 times is connected with 4 hydraulic jacks 4 by the screw crosswise fixed, the piston rod of 4 hydraulic jacks 4 is connected with 4 panel 2 outer ends respectively by nut, be connected with right oil pipe 5 and left oil pipe 6 on the hydraulic jack 4, right oil pipe 5 is connected with hydraulic jack 4 left and right sides hydraulic cavities respectively with left oil pipe 6, and right oil pipe 5 and left oil pipe 6 are connected with the two-position three way magnetic valve of machine tool hydraulic system.
Operation principle:
When the oil-feed simultaneously of the left and right sides of 4 hydraulic jacks 4 hydraulic cavities, ram boring and milling head is in zero-bit at XZ plane inner main axis axis, and promptly main-shaft axis is perpendicular to workbench.
Left oil pipe 6 oil-feeds simultaneously of 2 hydraulic jacks 4 when about slip crate 1 rear side, right oil pipe 5 oil returns simultaneously of 2 hydraulic jacks 4, hydraulic jack 4 drives 2 panels 2 of rear sides respectively and be moved to the left to the right, just promote 2 panels 2 of rear side to slip crate 1 medial movement, the panel sectional dimension thickens, and makes slip crate produce a thrust backward; Right oil pipe 5 oil-feeds simultaneously of 2 hydraulic jacks about slip crate 1 front side simultaneously, left oil pipe 6 oil returns simultaneously of 2 hydraulic jacks 4, hydraulic jack 4 drives 2 panels 2 in front sides respectively and move right left, just promote 2 panels 2 in front side side shifting outside slip crate 1, panel sectional dimension attenuate, make slip crate produce a gap of displacement backward, thereby make main-shaft axis in the XZ plane, realize hypsokinesis.
Left oil pipe 6 oil-feeds simultaneously of 2 hydraulic jacks 4 when about slip crate 1 front side, right oil pipe 5 oil returns simultaneously of 2 hydraulic jacks 4, hydraulic jack 4 drives 2 panels 2 in front sides respectively and be moved to the left to the right, just promote 2 panels 2 in front side to slip crate 1 medial movement, the panel sectional dimension thickens, and makes slip crate produce a thrust forward; Right oil pipe 5 oil-feeds simultaneously of 2 hydraulic jacks 4 about slip crate 1 rear side simultaneously, left oil pipe 6 oil returns simultaneously of 2 hydraulic jacks 4, hydraulic jack 4 drives 2 panels 2 of rear sides respectively and move right left, just promote 2 panels 2 of rear side side shifting outside slip crate 1, panel sectional dimension attenuate, make slip crate produce a gap of displacement forward, thereby make main-shaft axis in the XZ plane, realize leaning forward.
As mentioned above, this ram boring and milling head main-shaft fore-and-post inclination automatic adjusting device principal character is to change existing panel 2 relative fixed into relative slip, main 4 hydraulic jacks 4 of machine tool control system control that adopt, control the structure of panels 2 positions again by 4 hydraulic jacks 4, utilize panel 2 with respect to slip crate 1 inside and outside characteristic of sliding, change the panel sectional dimension, realize adjusting automatically the ram boring and milling head main-shaft axis can be leaned forward in the XZ plane, three kinds of states of zero-bit and hypsokinesis, the state of adjusting to needs by programme-control according to the processing needs can be eliminated the generation of " sweeping cutter " phenomenon.Thereby can improve the moving beam gantry boring and milling machine machining accuracy of numerical control, prolong cutter life.And this device action is reliable, accurate positioning.
The experiment on the moving beam gantry boring and milling machine of numerical control of this ram boring and milling head main-shaft fore-and-post inclination automatic adjusting device obtains remarkable effect, will have surface roughness now by 6.3 (R
a) bring up to 1.6 (R
a), the cutter blade durability improves 3 times.
