The utility model content
Technical problem to be solved in the utility model is: a kind of raising working (machining) efficiency is provided, guarantees the milling power device with movable workbench of machining accuracy simultaneously.
Solve this technical problem, the technical solution of the utility model is: a kind of milling power device with movable workbench, comprise the slide mechanism that is connected with workbench, the milling unit head that milling cutter is installed, described milling unit head is fixed in the top of slide mechanism.
The described slide mechanism that is connected with workbench comprises lower slider, be positioned at the lower slider top cross slide seat, be positioned at the upper saddle of cross slide seat top, the bottom of cross slide seat has the cross slide seat lower guideway that is slidingly connected with lower slider, the top of cross slide seat has the cross slide seat upper rail that is slidingly connected with upper saddle, and the cross slide seat upper rail is vertical mutually with the center line of cross slide seat lower guideway; Be provided with between described cross slide seat and the described lower slider and make both produce the screw mandrel I of relative displacement, the axis of this screw mandrel I and cross slide seat lower guideway center line are parallel to each other; Be provided with between described upper saddle and the described cross slide seat and make both produce the screw mandrel II of relative displacement, the axis of this screw mandrel II and cross slide seat upper rail center line are parallel to each other.
The end of the orthogonal screw mandrel I of described two axis, screw mandrel II is respectively arranged with the motor of driving.
The described motor that drives screw mandrel I, screw mandrel II rotation respectively is connected with digital control system.
The milling unit head of described installation milling cutter is connected with variable-frequency motor, and this variable-frequency motor is connected with digital control system
The utility model adopts such structure, milling unit head and workbench in the end of platen can produce relative motion, milling cutter is installed on the milling unit head, can process workpiece in the end of workbench separately, meanwhile the cutter on the milling-boring machine is also processed workpiece, can on two orthogonal directions, process like this workpiece, reduced the number of times of workpiece location and installation, once mounting just can be finished the processing to workpiece, therefore, easy to process, improved working (machining) efficiency, guaranteed machining accuracy simultaneously; For the big arm class part that the support holes inner face is arranged of Milling Process difficulty in the engineering machinery, adopt the milling power device of the utility model with movable workbench, then be convenient to processing.

The specific embodiment
As shown in Figure 1 and Figure 2, with the milling power device of movable workbench, comprise the slide mechanism 4 that is connected with workbench 1, the milling unit head 2 that milling cutter is installed, milling unit head 2 is fixed in the top 4 of slide mechanism.Slide mechanism 4 comprises upper saddle 6, cross slide seat 12, lower slider 11, screw mandrel I10, screw mandrel II7, the bottom of cross slide seat 12 has two parallel cross slide seat lower guideways 9, the top of cross slide seat 12 has two parallel cross slide seat upper rails 8, cross slide seat upper rail 8 and the mutual vertical across of the center line of cross slide seat lower guideway 9, article two, cross slide seat lower guideway 9 is slidingly connected with lower slider 11, realize vertically moving by screw mandrel I10, the end of screw mandrel I10 has the motor that is connected with digital control system 5 of a driving.Article two, cross slide seat upper rail 8 is slidingly connected with upper saddle 6, realizes in-movement by screw mandrel II7, and the end of screw mandrel II7 also has the motor (not shown) that is connected with digital control system of a driving.Milling unit head 2 is fixedlyed connected with upper saddle 6, and milling unit head 2 is connected with variable-frequency motor 3, and this variable-frequency motor 3 is connected with digital control system.
During use, the milling power device of milling-boring machine is installed on an end of milling-boring machine workbench, when control motor-driven screw mandrel II by digital control system, screw mandrel II rotates, and milling unit head 2 is done the horizontal cross feed motion of workbench 1 length direction along cross slide seat upper rail 8 together with upper saddle 6; When control motor-driven screw mandrel I by digital control system, screw mandrel I rotates, milling unit head 2 is together with upper saddle 6, cross slide seat 12 linear longitudinal movement along the cross slide seat lower guideway, and milling unit head is done the vertical horizontal movement of work platform length direction 2 this moments.
The milling cutter of installing on the milling unit head can be processed workpiece in the end of workbench separately, cutter on the milling-boring machine also can be processed other positions of workpiece simultaneously, reduced the number of times of workpiece location and installation, even once mounting just can be finished the processing to workpiece, therefore, reduce process time, improved working (machining) efficiency, guarantee machining accuracy simultaneously, and easy to operate.For the big arm class part that the support holes inner face is arranged in the engineering machinery, adopt the utility model with the lathe movable workbench mill the pin power set, solved the difficult problem of the Milling Process of small distance support holes inner face.
The utility model is not limited to said structure, and the vertical or horizontal motion that slide mechanism can only be realized by motor-driven also can realize in-movement by motor-driven, vertically moves by manual operation and realizes.
