The simulative handle comprises a holder, an electromagnetic damping disk, a rotary encoder, and handles provided with a rotary shaft. The holder is provided with a flange and a tube. The flange is fixed on a bench drill. The rotary shaft is positioned on the flange through a bearing. The electromagnetic damping disk and the rotary encoder are disposed in the tube and are respectively linked to the rotary shaft. The handles are provided with a handle base and are fixed at the end of the rotary shaft through the handle base. The handle base covers an opening of the tube. The rotary encoder is electrically connected with a servo motor and controls action of the servo motor. A current sensor connected to a power input end of the servo motor acquires change of current and is connected to an electromagnetic coil of the electromagnetic damping disk through an amplifier circuit. The simulative handle is capable of controlling action of the servo motor and timely feeding back feed resistance of the bench drill during operation, and helps operators judge magnitude of the feed resistance and regulate feed amount so as to regulate feed speed by hand feel and protect a drill bit from damage.
Description
Technical field:
The invention belongs to plant equipment field, particularly a kind of numerical control bench drill simulating handle.
Background technology:
Bench drill also claims bench drill, is widely used in field of machining, can boring on workpiece, the operation such as reaming, fraising and tapping.Manually the structure of bench drill, roughly includes base, column, main spindle box, main shaft, rack sleeve, gear shaft and handle etc.Add man-hour, rotate by turning handle driven gear axle, thereby drive the vertical tooth bar on the rack sleeve that engages with it to move up and down, complete F.F., attack, rewind down, and combination is moved.Such bench drill not only troublesome poeration, labour intensity is large, and a people can only control a machine, and production efficiency is relatively low, especially all the more so to batch machining.For this reason, the digital improvement of common manual bench drill, becomes inevitable.Existing numerical control bench drill, all with numerical control tank or electric-control board, replaces traditional mechanical type feeding handle by servomotor, by the mode control servomotor action of programming, realizes the target of automated job.By practice for many years, still there is limitation in numerical control bench drill, and one, bench drill operator are a line skilled worker, and programming, for them, is difficult to incision for the moment; Two, bench drill is except manufacturing batch workpiece, the material difference of also processing some nonstandard scattered workpiece, especially these workpiece is large, processing specification complexity, although can manually process by the operating key in CNC Panel, but the resistance cannot judge drilling time, causes the faults such as drill bit damage.How on numerical control bench drill, to merge manual bench drill handle function, become the object of the present invention's research.
Summary of the invention:
The object of the invention is to design a kind of numerical control bench drill simulating handle with feeding control and resistance feedback.
Technical solution of the present invention is achieved in that a kind of numerical control bench drill simulating handle, it is characterized in that including holder, electromagnetic damping dish, rotary encoder, handle with rotating shaft; Holder has a ring flange and a cylindrical shell, is fixed on bench drill by ring flange, and described rotating shaft is positioned on ring flange by bearing; Described electromagnetic damping dish and rotary encoder are contained in cylindrical shell, and link with rotating shaft respectively, with one handle seat, be fixed on roller end by this handle set, and lid are located at described cartridge openings place on handle; Described rotary encoder is electrically connected with servomotor, controls servomotor action; Be connected on the current sensor on servo motor power supply input end, gather the solenoid that curent change connects electromagnetic damping dish after by amplifying circuit.Simulating handle both can have been controlled servomotor action, and the feeding damping also can in good time feed back drilling machine work time helps operation people judge feeding drag size and regulate the amount of feeding." there is feel " thereby realize hand feed, by the perception of hand and carry out speed of feed adjusting, to protect drill bit not damaged.
Described electromagnetic damping dish comprises the solenoid and the magnechuck that are fixed on holder cylindrical shell, and is fixed on the dampened disk of iron content in rotating shaft.
Described electromagnetic damping dish refers to magnetic powder brake.
The present invention have be skillfully constructed, reasonable in design, the effective lever operated function of analog mechanical, realize and conventional manual bench drill seamless switching, in good time perception damping situation, carries out speed of feed adjusting by the perception of hand, not damaged with protection drill bit, be particularly useful for the processing of scattered workpiece; More important point, this simulating handle can coordinate the self-learning function of numerical control tank, record simulating handle operating process by the process chip in numerical control tank, then again by numerical control tank control bench drill, repeating manual flow process processes workpiece, rely on the limitation of programming thereby reduce numerical control bench drill, solve the universal bottleneck of numerical control bench drill.
