Abstract
The invention relates to an overturning tool changing mechanism of a rotary machine tool. The mechanism is characterized in that a facing cutter is arranged at the lower part of a power head box body; a movable supporting plate is fixed on the chassis of the machine tool, the movable supporting plate is provided with a U-shaped open slot; the bottom surface of the power head box body is supported on the top surface of the movable supporting plate; the facing cutter is positioned below the movable supporting plate; the upper part at the side face of the power head box body is pivoted on a triangular mounting rack of the movable supporting plate through a spindle seat and a spindle; and one end of an electric push rod is pivoted on the side face of the power head box body through a push rod frame, and the other end of the electric push rod is pivoted on the push rod supporting seat of the movable supporting plate. According to the mechanism provided by the invention, the power head box body is supported and hinged on the movable supporting plate, and the linear motion of the electric push rod is converted into the overturning motion of the power head of the machine tool, so that the facing cutter faces to a slightly oblique upside azimuth instead of facing downward, an operator can conveniently observe and change tools, the tool changing speed is quickened, the processing efficiency of the machine tool is improved, and the mechanism provided by the invention has good economic benefits.
Description
Technical field
The present invention relates to field of machine tool equipment, especially a kind of for processing the upset cutter-exchange mechanism of the rotary machine tool of large-diameter workpiece.
Background technology
In ocean, the engineering field such as oil, heavy-duty machinery, in structures such as hauling rope, coastal waters floating structure, radiotelescope and pressure vessel, need superhuge disc-like workpiece, the ring-type class surface of these workpiece all needs processing, traditional lathe cannot be processed at all, needs the special purpose machine tool of huge revolving class.The Chinese patent < < CN201110202251.4---laser of the applicant's application discloses a kind of around the rotating lathe of central point from horizontal big disk finishing machine > >, the lathe other end is provided with milling unit head, add man-hour, Milling Process is carried out on walking limit, surface of the work top in one end of milling unit head.Yet because workpiece size is all superhuge, the surface of the work range of work is large, milling workload is large, and the indexable carbide-tipped milling cutter blade of employing easily weares and teares, and need to change in time.Because lathe is superhuge, and the direction of milling head is downward, and the feed distance that milling head moves up and down is generally relatively little, and the tool changing space between workpiece and facing cutter is very little, and workpiece can not move again, and unusual trouble just during tool changing, is even difficult to operation like this.
Summary of the invention
The problem of the applicant's lathe tool changing difficulty during for above-mentioned large-scale workpiece Surface Machining, provides a kind of upset cutter-exchange mechanism of revolution class lathe rational in infrastructure, and it is easy to operate, tool changing efficiency is high, cost performance good.
The technical solution adopted in the present invention is as follows:
A kind of upset cutter-exchange mechanism of rotary machine tool, facing cutter is arranged on the bottom of unit head box body, and drive by motor, mobile pallet is fixed in the frame of lathe, on mobile pallet, offer U-shaped open slot, the bottom surface of unit head box body is carried on the end face of mobile pallet, and the neck of facing cutter is through U-shaped open slot, and facing cutter is positioned at the below of mobile pallet; The top, side of unit head box body, is articulated in by shaft seat, rotating shaft on the triangle installing rack of mobile pallet; One end of electric pushrod is articulated in unit head box body side by push-rod frame, and the other end is articulated on the handspike bearing of mobile pallet.
Further improvement as technique scheme: the front of mobile pallet is provided with pressing plate, pushes down the flange of unit head box body.
Beneficial effect of the present invention is as follows:
The present invention carries and is hinged on mobile pallet by unit head box body, the rectilinear motion of electric pushrod is converted to the flip-flop movement of power unit of machine tool, thereby make facing cutter direction by the original orientation that has become deflection oblique upper downwards, facilitated operator to observe and allowing blade replacement more, accelerated the speed of tool changing, improve the working (machining) efficiency of lathe, there is good economic benefit.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is schematic perspective view of the present invention.
Fig. 4 is the schematic diagram after Fig. 3 overturns.
In figure: 1, facing cutter; 2, electric pushrod; 3, handspike bearing; 4, rotating shaft; 5, shaft seat; 6, installing rack; 7, push-rod frame; 8, mobile pallet; 9, unit head box body; 10, motor; 11, U-shaped open slot; 12, pressing plate.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1 to Figure 3, facing cutter 1 of the present invention is arranged on the bottom of unit head box body 9, and drive by motor 10, mobile pallet 8 is fixed in the frame of lathe, on mobile pallet 8, offer U-shaped open slot 11, the bottom surface of unit head box body 9 is carried on the end face of mobile pallet 8, and the neck of facing cutter 1 is through U-shaped open slot 11, and facing cutter 1 is positioned at the below of mobile pallet 8.The front of mobile pallet 8 is provided with pressing plate 12, pushes down the flange of unit head box body 9.The top, side of unit head box body 9, is articulated in by shaft seat 5, rotating shaft 4 on the triangle installing rack 6 of mobile pallet 8.One end of electric pushrod 2 is articulated in power unit of machine tool box body 9 sides by push-rod frame 7, and the other end is articulated on the handspike bearing 3 of mobile pallet 8.
When cutter wear needs tool changing, unclamp the securing member on pressing plate 12, start electric pushrod 2, push rod straight line stretches out LAP, propulsion power head box body 9 overturns centered by the rotating shaft 4 of its upper articulation, and facing cutter 1 is together with motor 10 upsets on top, and facing cutter 1 converts orientation obliquely to by original downward orientation, as shown in Figure 4, now operating personnel just can carry out the tool changing operation of cutterhead or blade easily.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention is referring to claim, and without prejudice to spirit of the present invention in the situation that, the present invention can do any type of modification.
