Abstract
The utility model relates to a digital control deep hole drilling and boring machine. The body of the drilling and boring machine is beneath a machine tool, and a headstock is fixed at the left end of the body. A towing bracket and a center frame are orderly arranged on the right part of the headstock. The middle part of the body is an oil charger, and a directing station is in front of the oil charger. A boring bar bracket is at the right part of the oil charger, and the farthest right end of the body is a carriage feeding system. A servomotor connects with a gearbox and an input shaft via a torque limiter. Via a worm gear, a worm screw and gears, the speed is reduced. A long shaft penetrating through the carriage is driven. The speed of both ends of the long shaft is reduced by a pinion gear and a big gear, which makes gears on both ends of the long shaft and a screw rack in synchromesh. Thus, the feeding and quick movement of the carriage is realized. The torque limiter and a limit switch are arranged on the servomotor. A boring bar fixing bracket is arranged on the carriage. A bolt presses a gland, and the boring bar is locked by a sleeve. The digital control deep hole drilling and boring machine guarantees the processing accuracy and improves the working efficiency of machine tools.
Description
Affiliated technical field
The utility model relates to a kind of machining equipment, especially adopts the CNC deep-hole drilling ﹠ boring machine of digital control and interior chip removal method deep hole processing.
Background technology
At present, prior art is TK2120 deep hole drilling and boring machine (our company's production), and lead screw transmission is adopted in former machine tool dragging plate feeding, and promptly servomotor drives the feeding planker and does feed motion by being fixed on the reduction box deceleration rear drive leading screw rotation of a body tail end; Fast moving realizes by a fast speed motor.
Former machine tool guideway is a prismatic and a rectangular configuration form, and it is bigger that its guidance quality is influenced by the cutting moment of torque; Because feed screw is longer, the leading screw precision is difficult to improve, and makes the transmission instability, has influenced the precision of processing work; Because quick driven by motor planker rapid movement, the planker position is uncertain, is difficult to realize the automatic circulation of processing, and has influenced the working (machining) efficiency of lathe.
Summary of the invention
In order to overcome existing workpiece machining accuracy instability, the utility model provides a kind of planker on rectangular guideway, by the horizontal diclinic rack-and-pinion of driven by servomotor, drive planker feeding and rapid movement, guarantee the stable of feeding transmission, improve the workpiece machining accuracy, improve the working (machining) efficiency of lathe.
The technical scheme that its technical problem that solves the utility model adopts is: CNC deep-hole drilling ﹠ boring machine mainly by bed body, headstock, bracket, centre frame, planker feed system, bore boring bar support, chip removal bucket, cooling system, directing station, award oily device etc. and form.The bed body is positioned at the lathe below, and left end is being fixed headstock on the bed body, and the headstock right side is followed successively by bracket, centre frame, and bed body middle part is for awarding oily device, and directing station is positioned at awards oily device front end, awards the oily device right side for boring boring bar support, and bed body low order end is the planker feed system.When its planker is done feed motion, servomotor connects with the reduction box power shaft by torque limiter, after worm and gear and gear reduction, be transferred on the major axis that passes planker, after slowing down by pinion and gear wheel in its two ends, make two end axles gear and helical rack synchro-meshing, realize the feeding and the rapid movement of planker.Torque limiter and restricted switch are arranged on the servomotor, and the two ends reduction box is installed in planker two lateral surfaces respectively, and the boring bar of boring fixed mount is arranged on the planker, compresses gland by bolt, finally will bore boring bar locking by lining.
The beneficial effects of the utility model are that by the transmission of the horizontal diclinic rack-and-pinion of AC servo machinery driving, drive planker integral body is done feeding or rapid movement, realizes boring boring bar and stablizes feeding, has guaranteed the precision of processing work, improves the working (machining) efficiency of lathe.

The specific embodiment
In Fig. 1, Fig. 2, lathe bed (1) upper left side is equipped with headstock (2), is mainly used in clamping and drives the workpiece rotation.Cooling fluid flows back to fuel tank by chip removal bucket (3).Bracket (4) and centre frame (5) are mainly as the workpiece supplemental support.Award oily device (6) and be positioned at the lathe bed middle part, be mainly used in workpiece and hold out against and seal cooling fluid, and deep hole tools is led.Directing station (7) is positioned at awards oily device front end, and there is swing arm the lower end, can move within the specific limits, turn round.Boring boring bar leading truck (8) uses mainly as boring the boring bar guiding.Planker feed system (9) is positioned at the lathe bed right-hand member, by the driven by servomotor reduction box, drives both sides helical gear tooth bar at last and is synchronized with the movement, and realizes the feeding and the rapid movement of planker; Cooling system (10) is positioned at the lathe back, and mainly acting as provides high-pressure coolant, washes away smear metal.
In the planker feed system structural representation shown in Fig. 3, Fig. 4, vertical view, servomotor (25) connects with worm screw (11) by torque limiter (27), after worm gear (12) and gear (13) and gear (14) deceleration, be transferred on the major axis (15) that passes planker (17), after slowing down with gear wheel (18) by pinion (16), (21) in its two ends, make two end axles gear (19) and helical rack (20) synchro-meshing, realize the feeding and the rapid movement of planker.When occurring moment of torsion above setting value, torque limiter is thrown off, and touches limit switch (26) simultaneously, sends signal, makes the servomotor stop motion.Bore the fixing of boring bar, compress gland (24), finally will bore boring bar locking by lining (23) by bolt (22).
