Abstract
The utility model belongs to the technical field of processing machinery and discloses a numerical control drilling machine with an internal positioning induction switch. The numerical control drilling machine with the internal positioning induction switch comprises a spindle, a spindle box, a main motor and the like, the spindle box is arranged on a base through a vertical column, the spindle is arranged in the front of the spindle box, and a spindle sleeve is sleeved outside the spindle. The positioning induction switch which is connected with a controller and used for detecting the axial position of the spindle is arranged in the spindle box, and an induction head on the positioning induction switch corresponds to a vertical positioning groove arranged on the side face of the spindle sleeve. When the positioning groove ascends along with the spindle to a prismatic table at the lower end of the positioning groove to face the induction head of the positioning induction switch, the controller enables a stepping motor to stop and complete resetting. The induction switch for detecting the axial position of the spindle is arranged inside the spindle box, and the induction switch can be protected effectively and can be prevented from misoperation or damage due to the fact that the induction switch is near to a drill bit to be affected by drillings. The induction switch is mounted extremely stably and precisely, and machine tool action stability is improved greatly.
Description
Technical field
The utility model belongs to the Machining Technology field, relates to a kind of machined rig, specifically a kind of digital control type drilling machine.
Background technology
Drilling machine is a kind of mainly lathe of machining hole on workpiece, can be divided into upright drill, bench drill, horizontal drilling machine and radial drilling machine.Drilling machine structurally mainly is comprised of main shaft, main spindle box, main motor etc., and described drill bit is assemblied in described main shaft lower end, and described main shaft vertically is arranged in the main spindle box.Main spindle box is installed on the column, column lower end has base, the main shaft upper end is provided with belt pulley, main motor is arranged on the main spindle box rear portion, output shaft is parallel with main shaft, the main motor output shaft end also is provided with belt pulley, is linked by driving belt with main shaft upper end pulley disc, consists of the transmission mechanism of drill bit main motion.The work top of general miniature bench type drilling machine bench type drilling machine directly is processed to form at base.Vertical drilling machine then general relative bench drill is higher, can establish in addition special work top above base.Beam drill is mainly large-sized drill machine, and the range of work is large, compares with common desk-top or upright drill, and its main spindle box not only can rotate and can also relatively move around column on rocking arm.
The main motor of early stage drilling machine mainly by hand switch control, then finished by the manual drives feeding drive mechanism by feed motion.Along with emerging of Servo Drive Technology's, Numeric Control Technology is widely applied in Machine-Tool Control.Numerical control drilling machine has added the controller that is used for driving the servo step motor of feeding drive mechanism and is used for control servomotor and Ge Lu electric switch on traditional rotated bed basis.
In existing numerical control drilling machine, the control of axis feeding speed and the amount of feeding realizes by rotating speed and the revolution (anglec of rotation) of control servomotor that mainly the playback action is then finished by the servomotor counter-rotating.But the amount of feeding is a relative value, guarantee accurate working depth, need to improve as far as possible the positioning accuracy of main shaft initial bit (zero feeding position).To this, improve the initial bit precision and mainly contain two improvement directions, one improves feeding drive mechanism, improves the transmission accuracy of feeding drive mechanism, with the difference of reduction transmission system forward transmission and reverse drive.Its two, increase the initial bit location mechanism.Because the feeding drive mechanism of bench drill adopts gear drive more, improves each linkage part precision, realize that the gap that is meshed between the teeth infinitely dwindles, difficulty is relatively large.Existing numerical control bench drill is mostly selected the latter, that is, in the position near the main shaft lower end one location is set and uses inductive switch, links to each other with controller, and this location uses the inductive head of inductive switch over against spindle axis.Its principle is that when iron block was arranged near inductive head, iron block disturbed the magnetic field of inductive sensor, caused curent change in the inductance., start working at least when main shaft begins to reset with inductive switch in described location, the inductive head that rises to inductive switch when the boss of rack sleeve lower end over against the position, inductive switch is triggered, send a signal to immediately controller, the controller response also stops servomotor, resets and finishes.
Existing location mainly contains 2 deficiencies with the setting of inductive switch, and one, inductive switch is arranged on the main spindle box below, from drill bit close to, in workpiece process, when the iron filings that taken up by drill bit fly over before the inductive head of inductive switch once in a while, can cause the inductive switch misoperation.Two, the workpiece debris that is taken up by drill bit is whiplike High Rotation Speed under the drive of drilling bit high-speed rotary, have very large impact.On the one hand, because inductive switch is arranged on the main spindle box below, in case hit by iron filings, be easy to cause damage; On the other hand, because existing inductive switch operated by rotary motion is being fixed on the main spindle box supported underneath plate, examine filter to the very light in weight of inductive switch own, for Cost reduction, this gripper shoe all adopts thinner sheet material, after inductive switch or gripper shoe were hit by iron filings, gripper shoe easily deformed, and then causes the inductive switch change in location, or depart from main shaft, finally malfunctioning, or the deflection main shaft, bump against damage with rack sleeve.Three, because outside inductive switch is exposed to, when the time long afterwards, the dust in the environment gathers when too much at inductive head, can cause inductive switch malfunctioning, therefore needs operating personnel's cleaned at regular intervals inductive switch, brings very burden to operating personnel.
