Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
As illustrated in fig. 1 and 2, the band-saw machine tool of the present invention includes post 1, main motion servomotor 2, saw frame 3, actively band saw wheel 4, saw frame support pin 5, clamp system 7, workbench feed mechanism 8, feed mechanism 9, feed servo motor 10, lathe bed 11, feeding lead 12, lower support spring 13, big column 14, driven band saw wheel 15, saw frame swing guiding bolt 16, swing mechanism 18, upper support spring 19, wobble servo motor 20, strainer 21, workbench 22, saw band 23 and crossbeam 25. The operation principle of sawing operation is: workpiece 6 is sent into workbench 22 by workbench feed mechanism 8; Workpiece 6 is clamped on workbench 22 by clamp system 7; 2 feed servo motors 10 that spacing is arranged, drive 2 feed mechanisms 9 (feed screw nut pair), guiding by 2 feeding leads 12, form sawing feed motion, substantially improve feeding displacement accuracy and there is good precision stability, thus improve the sawing precision of workpiece; One end of saw frame 3 is hinged by saw frame support pin 5 and post 1, and the other end is fixed with saw frame and swings guiding bolt 16; Saw frame swings guiding bolt 16 and embeds in the arcuate groove 17 that big column 14 is offered; Crossbeam 25 is supported on lathe bed 11 top by post 1 and big column 14; Upper support spring 19 connects 3 crossbeams 25 and saw frame top, and lower support spring 13 connects bottom lathe bed 11 and saw frame 3; Wobble servo motor 20 controls swing mechanism 18 and moves up and down, and swing mechanism 18 drives the saw frame 3 arcuate groove 17 along big column 14 to make reciprocally swinging, is conducive to chip breaking and chip removal, it is thus possible to be effectively improved cutting-rate; Actively band saw wheel 4 and driven band saw wheel 15 are arranged on saw frame 3; Saw band 23 is wrapped in actively and on driven band saw wheel, and by strainer 21 tensioning near driven band saw wheel; Main motion servomotor 2 drives actively band saw wheel 4, makes saw band 23 produce main motion, thus realizing the sawing operation of workpiece.
As in figure 2 it is shown, strainer 21 is made up of hydraulic tensioning cylinder and slide block; Hydraulic tensioning cylinder drives slide block to compress the installation axle of driven band saw wheel 15; Two saw band guiding mechanism 24 spacing are fixed on saw frame 3, and saw band is play the guiding role, and make saw band part between two saw band guiding mechanisms 24 produce drift angle.
Fig. 3 reflects lathe bed 11 in the horizontal plane, the position relationship of post 1, big column 14, feed mechanism 9, feeding lead 12 and lower support spring 13.
Fig. 4 reflects the structure of saw frame support pin 5. Saw frame support pin 5 is cased with rolling bearing, can around fulcrum flexible rotating when making saw frame 3 be bearing on post 1.
Fig. 5 reflects that saw frame swings the structure of guiding bolt 16. Saw frame swings guiding bolt 16 and is cased with rolling bearing, and rolling bearing is smart scroll in the arcuate groove 17 of big column, makes the saw frame 3 arcuate groove 17 along big column make reciprocally swinging, is conducive to chip breaking and chip removal, it is thus possible to be effectively improved cutting-rate.
This workpiece moves the band-saw machine tool that saw frame swings, maximum difference with normal tape blade saw machine tool is: the workpiece in order to realize the present invention moves and saw frame swings mode, the overall structure of band-saw machine tool and layout and existing product make a big difference, the workpiece travel mechanism set up and saw frame swing mechanism are that existing product is unexistent, specific as follows:
(1) the cutting main motion of normal tape blade saw machine tool and the task of feed motion undertake by saw frame. The band-saw machine tool of the present invention, its saw frame only undertakes the task of cutting main motion, does not undertake the task of feed motion. Feed motion task is undertaken by workbench. Therefore, the technology pattern of sawing there occurs change. Some advantages that arise therefrom is, workbench can increase rigidity, by the structural design measure such as feed screw nut pair and linear motion guide rail, improve the precision of table feed motion and the retentivity of precision, thus ensure that the machining accuracy of sawing workpieces, reach the purpose of " with saw for car ", " with saw for milling ". It is particularly suitable for the Cutting indexes of the high middle-size and small-size workpiece of required precision.
(2) the saw frame perpendicular cuts workpiece of normal tape blade saw machine tool, in cutting process, saw band is cutting main motion and vertical feed motion only, is not easy chip breaking on the one hand, and the between cog of saw band is easily blocked in chip on the other hand, is unfavorable for the raising of cutting-rate. Meanwhile, saw band is easily generated heat, and service life reduces. Therefore, the present invention is additionally arranged the weave mode of saw frame, make between saw band and workpiece, there are three motion synthesis such as cutting main motion, vertical feed campaign and swing, its objective is to make saw band in cutting process, carry out micro-swinging, be conducive to chip breaking and chip removal, it is thus possible to be effectively improved cutting-rate, extend saw band service life.
New Sawing Process needs equipment and realizes, and therefore, the present invention devises workpiece and moves feed gear of work level and the saw frame micro-swinging device of sawing. Meanwhile, the technological process of numerical control saw cutting is developed, as shown in Figure 6.
Fig. 6 is the numerical control saw cutting process flow chart of the present invention. Main motion servomotor, feed motion servomotor and wobble servo motor are each configured with controller and photoelectric speed detecting device. After start, determine the operation of the best by parameter optimization controller and control parameter. Main motion controls loop, by photoelectric speed detecting device and main motion servomotor, the speed of band saw wheel is controlled, to ensure to run in the parameter area optimized. Feed Motion Control loop, by photoelectric speed detecting device and feed motion servomotor, is controlled the feed speed of workbench, to ensure to run in the parameter area optimized. Oscillation controlling loop, by photoelectric speed detecting device and wobble servo motor, is controlled the micro-swinging speed of saw frame, to ensure to run in the parameter area optimized.
