Abstract
The invention relates to a processing mechanism, especially a NC drilling machine. In the invention one end of output shaft of main motor is used to drive gear-nut pair rotate through gear meshing and drive and drive motor seat, main motor, chuck and bit move vertically to the workpeice under the guide action of smooth rod. The other end of output shaft of main motor drives bit rotate through the chuck. When the main motor rotates clockwise the bit moves downwards to accomplish drilling hole and when the main motor rotates counterclockwise the bit moves upwards to retreat from workpeice. If location data of holes in a line are input to controller the controller controls servo motor. As the rotating angle of servo motor is controlled the location of bit in the line can be controlled. On the chuck there is a speed sensor. In drilling when the bit is blocked the bit can be retreated. The speed of main motor can be adjusted in variable frequency so as to adapt different cutting force and drilling speed. The invention simplifies the structure of NC drilling machine and decreases the cost. It is suitable for workpeice with multiple holes in a line.
Description
Affiliated technical field
The present invention relates to a kind of processing equipment, particularly a kind of numerical control drilling machine.
Background technology
Present numerical control drilling machine mostly is the multi-axis numerical control drilling machine, and common gantry numerical control drilling machine has x, y axle to carry out the control of plane bore position, and the z axle carries out the control of vertical feed, need with three servomotors and a spindle motor, so complex structure, the cost height.The processing of some part, process such as the crossbeam on the Cantilevered screen of the vibratory sieve that is widely used in metallurgy industry, only require on one or two straight lines and bore porous,, will cause the raising of the significant wastage and the processing cost of capacity of equipment if adopt existing numerical control drilling machine processing.Therefore, resemble the processing of vibratory sieve Cantilevered screen crossbeam and other need bore porous on straight line workpiece at present and still adopt common table to creep into the manual processing of row, its working (machining) efficiency is low, low precision, and labour intensity is big.
Summary of the invention
In order to overcome common multi-axis numerical control drilling machine complex structure, the cost height, be unfavorable for only needing on one or several straight line, to bore the deficiency of promoting in the workpiece processing of porous, the invention provides a kind of numerical control drilling machine, only needing a servomotor and spindle motor is power, input hole just can get out the hole in required pitch-row and aperture point-blank fast, accurately apart from also using corresponding drill bit.
The technical solution adopted for the present invention to solve the technical problems is:
One end of main motor output shaft is by the rotation of gears engaged driven gear pair of nut, cooperate, be with motor cabinet in the gear nut pair outward with screw mandrel, and with the axial displacement of nut restriction motor cabinet and gear nut pair, the gear nut pair can be rotated in motor cabinet, the motor cabinet other end is enclosed within on the polished rod, and motor cabinet can move on polished rod.Moving motor cabinet of gear nut subband and main motor, chuck, drill bit under the guide effect of polished rod, are made the rectilinear motion perpendicular to workpiece, and the other end of main motor output shaft drives the drill bit rotation by chuck.
One end of polished rod and screw mandrel all is fixed on down to be connected and pulls, polished rod nut check, the other end of polished rod and screw mandrel is connected with upper junction plate and fixes with nut, and the switch base of position adjustable is arranged on the upper junction plate, and upper limit position switch and main motor switch are installed on the switch base.
Work-sheet pressing is on work top, on the straight line of workpiece, bore porous, its hole is in the location of rectilinear direction, be that position data input controller, the servo-driver in hole are controlled servomotor, the rotation of drive leading screw, with moving lower connecting plate, polished rod, the screw mandrel that is fixed together of leading screw nut engaged subband and be enclosed within gear nut pair on the screw mandrel, motor cabinet, main motor, chuck, drill bit along moving linearly on the line slideway of workpiece direction, the anglec of rotation of control servomotor can be controlled the position of drill bit on straight line.
When main motor main story, drill bit moves downward, and is rotated in the forward, and finishes drill tasks; When main motor anti-pass, the drill bit reverse rotation moves upward, and makes drill bit withdraw from workpiece.
When servomotor found bore position and stops, main motor was rotated in the forward, and drill bit moves downward.When boring is finished, after the gear nut pair is run into lower position switch, main motor reverse rotation, drill bit moves upward, and servomotor rotated after the gear nut pair was run into upper limit position switch, and drill bit moves along workpiece, up to next bore position, the servomotor stall begins new one and takes turns circulation, till the hole drill on the straight line is intact.
The chuck end of main motor is equipped with speed probe, and when drill bit is blocked when stopping boring by workpiece, speed probe detects stall signal, make main motor counter-rotating on the one hand, drill bit rises and withdraws from workpiece, makes the upper limit position switch open circuit on the other hand, and start main motor switch, upper limit position switch is inoperative when main motor is up to upper limit, and servomotor is failure to actuate, and main motor switch stops main motor, can carry out the repair of drill bit this moment, after reparation is finished, can pacify reset switch, make system recover normal.The upper limit position switch position can be adjusted, so that adapt to the workpiece of different-thickness.The speed governing of main motor variable ratio frequency changer is to adapt to different cutting force and penetration rate.
The base of work top, line slideway and servomotor is fixed on the frame.
Adjust the Work-sheet pressing position, can get out the hole on another center line.
The invention has the beneficial effects as follows:
1. simplified the structure of numerical control drilling machine, reduced cost, be convenient on straight line to bore in the workpiece processing of porous and apply;
2. the automaticity height does not need the workman to intervene in the brill porous process on a horizontal linear;
3. efficient height can be adjusted the boring stroke according to by the boring material thickness, rotating speed and move up and down adjustable-speed;
4. wide adaptability can bore the porous on one or more horizontal linear on section bars such as different angle steel, band steel;
5. repetitive positioning accuracy height.
