Abstract

The invention relates to a digital controlled drilling machine which can carry out stay and fixed point processing at any position, and the repeated depth of cut thereof can be controlled within 0.02mm, a servo motor is positioned on the upper end face of a hydraulic or a pneumatic bench drill by a speed reducer and drives a ball screw to rotate, the ball screw is connected with a connecting plateby a ball screw bearing seat, and the connecting plate is connected with a spindle sleeve and drives the spindle sleeve to make cut-advancing and cut-withdrawing movement. The digital controlled dril ling machine has the following advantages: 1. the depth of cut-advancing can be controlled to be within 0.02mm; and 2. the digital controlled drill is particularly suitable for deep hole processing, which can not only effectively guarantee product quality, but also can prolong the cutting life, thus reinforcing the rate of multipurpose utilization of machine tool.

Description

Numerical control drilling machine
Technical field
The present invention relates to a kind of processing of can doing at an arbitrary position to stop, fix a point, the depth of cut of its repetition can be controlled at 0.02mm with interior numerical control drilling machine, belongs to drilling machine and makes the field.
Background technology
CN101041188A, title " numerical control drilling machine ", he is by the rotation of gears engaged driven gear pair of nut with an end of main motor output shaft, and drive motor cabinet and main motor, chuck, drill bit, under the guide effect of polished rod, work is perpendicular to the motion of workpiece, and the other end of main motor output shaft drives the drill bit rotation by chuck.Main motor main story, drill bit is finished drill tasks downwards, main motor anti-pass, drill bit upwards withdraws from workpiece.Position data input controller, the servo-driver in hole on the straight line are controlled servomotor, and the anglec of rotation of control servomotor can be controlled the position of drill bit on straight line.Speed probe is arranged on the chuck, in the boring, can withdraw from drill bit during drill-pipe-sticking-head.The speed governing of main motor variable ratio frequency changer is to adapt to different cutting force and penetration rate.Servomotor in this numerical control drilling machine is not to be used for the controlling depth tolerance, but is used for the control position tolerance.
CN2767017Y, " numerical control drilling machine ", it is to have increased the mechanism that centers on original radial drilling machine, the workpiece automatically centering fixture, NC rotary table, orienting device reaches can realize lathe self-centering, part self-centering, and centering part direction after being connected with a servomotor on the feed mechanism, can by parts program automatic indexing and main shaft fast, the worker advances rewind down, thereby satisfies the specification requirement that processing valve body class connects screw.The wall drilling machine shakes in this numerical control drilling machine system, can't be used for upright drill.
CN2333468Y, " numerical control drilling machine ", it ties up to and is fixed with the guiding cover for seat on the workbench base plate, is fixed with guiding in it and goes up cover, leads and trap, and is between the two and be located at the two ends of turning round the guide finger on the axis of guide; Upper end at the revolution axis of guide is provided with mold rotation and anchor clamps, and the lower end is provided with spring, and is provided with clamping cylinder above anchor clamps.Stepper motor in this numerical control drilling machine is used for the processing to horizontal workpiece different rotary face, and can't be used for drilling machine.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of numerical control drilling machine that can control the feed precision accurately.
Design: in order to realize above-mentioned purpose of design.The utility model adopts the machining accuracy of servomotor controller structure control bench drill on the basis of existing bench drill, be major technique feature of the present invention.The purpose of doing like this is: on the appearance structure basis of existing vertical bench drill, adorned a servo motor, by high-precision ball screw, drive rack sleeve and do feed, the withdrawing motion, it can stop at an arbitrary position, fixed point processing, and the depth of cut that repeats can be controlled in the 0.02mm, control the workpiece processing of having relatively high expectations to be fit to the degree of depth, and under the electric-control system of man-machine interface, can be according to client's needs, the material of product and the requirement of processing technology, programme, cut machining functions, the disconnected machining functions of cutting to realize moving back automatically.
Technical scheme: numerical control drilling machine, servo motor is positioned at the upper surface of bench drill fuselage and drives the ball screw transmission by reductor, ball screw is connected with gusset piece by the ball screw bearing block, and gusset piece is connected with rack sleeve and drives rack sleeve does feed, withdrawing motion.
The present invention compares with the background skill, and the one, depth of cut can be controlled in the 0.02mm; The 2nd, be particularly suitable for deep hole machining, not only can guarantee the quality of product effectively, and improve cutter life, strengthened the comprehensive utilization ratio of lathe.
Description of drawings
Fig. 1 is the structural representation of Digit Control Machine Tool.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1.Numerical control drilling machine, it comprises bench drill, the manufacturing technology of bench drill and technology are prior art, are not described herein at this.Servo motor 3 is positioned at the upper surface of bench drill fuselage and drives ball screw 15 transmissions by reductor, ball screw 15 is connected with gusset piece 17 by ball screw bearing block 16, and gusset piece 17 is connected with rack sleeve 19 and drives rack sleeve 19 does feed, withdrawing motion.Feed screw nut's seat 9 be enclosed within the top of ball screw 15 and ball screw 15 upper ends by ball screw bearing block 8, bearing block gland 7, compacting ring 6, reductor base 5 and reductor adapter sleeve 4 with wait for an opportunity to obey motor 3 output shafts and be connected, ball screw 15 lower ends are connected with gusset piece 17 by ball screw bearing block 16 and push rod 18, and gusset piece 17 is connected with rack sleeve 19 with linear bearing flange 13 respectively.Spline spindle 20 be positioned at rack sleeve 19 lower ends and by be with on 11 in the motor belt wheel 10 by belt be enclosed within belt wheel 1 on the splined shaft 20 and constitute belt gear and drive spline spindle 20 and rotate, round nut 2 is screwed on the axle of belt wheel 1 side, motor 11 is connected on the fuselage 12, and guide pillar (standard axle) 14 is enclosed within the axis hole of gusset piece 17 and is positioned at the chamber of fuselage 12.
What need understand is: though the foregoing description is to the present invention's detailed text description of contrasting; but these text descriptions; it is simple description to mentality of designing of the present invention; rather than to the restriction of mentality of designing of the present invention; any combination, increase or modification that does not exceed mentality of designing of the present invention all falls within the scope of protection of the present invention.
