Definitions
- the present invention relates to an apparatus for automatically detecting the position of the cutting tool in the computerized numerically controlled lathe, more particularly to an apparatus for automatically detecting the position of the cutting tool in the computerized numerically controlled lathe which is capable of preventing overload operation of a driving motor by allowing an arm having a touch sensor mounted thereto to be safely stop at a position of detecting the cutting tool while the driving motor provided within a main body of a housing stops operating.
- FIG. 1 shows the conventional computerized numerically controlled lathe 10.
- the computerized numerically controlled lathe 10 comprises a frame 12 including a bed 12a, a headstock 14 for grasping and fixing one end of the work piece, which is fixed at one side of the frame 12, a tailstock 16 for grasping and fixing the other end of the work piece, which is sliderably positioned on the bed 12a in opposite to the headstock 14, a tool rest 18 for processing the work piece rotated between the headstock 14 and the tailstock 16 while moving along the longitudinal axis of the bed 12a on one side portion of the bed 12a of the frame 12, a control part (not shown) for controlling the headstock 14, the tailstock 16 and the tool rest 18.
- the work piece which is supported and rotated between the headstock 14 and the tailstock 16, is automatically processed by the cutting tool mounted to the tool rest 18 sliding on the bed 12a on a basis of the pre-programmed process condition.
- problems with the conventional computerized numerically controlled lathe as described above are that a cutting edge of the cutting tool for processing the work piece may be worn due to the friction between the cutting edge and the work piece and the processing precision of the cutting tool may deteriorate due to the change of the cutting tool's position.
- Another problem which is inherent to such known computerized numerically controlled lathe is that, when the old cutting tool has been changed with a new cutting tool, it is extremely difficult to obtain an accurate treatment of the work piece due to the difference of positions between the old cutting tool and the new cutting tool.
- FIG. 2 shows the apparatus for detecting a position of the cutting tool mounted to the computerized numerically controlled lathe, more particularly shows the apparatus for detecting the position of the cutting tool mounted to the headstock of the computerized numerically controlled lathe. As shown in FIG.
- the apparatus 20 for detecting the position of the cutting tool comprises an arm 22 having a touch sensor 22a for sensing the position of the cutting tool, a gear assembly 24 for pivoting the arm 22 toward the cutting tool, and a driving motor (not shown) for driving the gear assembly 24.
- the arm 22 having the touch sensor 22a is moved toward the cutting tool by means of the gear assembly 24 and then the cutting tool is brought into contact with the touch sensor 22a in accordance with the program that is preprogramedly input into the computerized numerically controlled lathe 10.
- the touch sensor 22a provides the control part of the computerized numerically controlled lathe with a sensing signal.
- the control part of the computerized numerically controlled lathe recognizes the position of the cutting tool. Then, the control part compares the detected value relative to the position of the cutting tool with a standard value and then calculates a displacement of the cutting tool. Finally, the control part provides the tool rest with the control signal for compensating the position of the cutting tool based on the displacement of the cutting tool calculated. Accordingly, it is possible to compensate the position of the cutting tool such that the front end's position of the cutting tool corresponds to the initial state of the cutting tool, which is preprogramedly set into the computer.
- the arm having the touch sensor must be maintained at a sensing position until the cutting tool is brought into contact with the touch sensor after moving the touch sensor to the sensing position so as to minutely compensate the position of the cutting tool. Accordingly, the driving motor must be continuously operated and thereby it may be damaged when an over load occurs in the driving motor.
- the present invention has been developed to solve the above- mentioned problems. It is an object of the present invention to provide an apparatus for detecting a position of a cutting tool which is capable of preventing over-load operation of a driving motor by allowing an arm having a touch sensor mounted thereto to be safely stop at a position of detecting the cutting tool while the driving motor provided within a main body of a housing stops operating.
- the present invention provides an apparatus for automatically detecting the position of the cutting tool in the computerized numerically controlled lathe, the apparatus comprising: a touch sensor for sensing the position of the cutting tool in the computerized numerically controlled lathe; an arm for moving the touch sensor to a predetermined position for sensing the position of the cutting tool, the arm being provided with a sensing dog, which protrudes from one side surface of the arm at a predetermined length; a gear assembly for pivoting the arm in a range of predetermined rotational angles, the gear assembly being combined to the arm; a driving motor for supplying the gear assembly with a driving force; and a housing for accommodating the gear assembly and the driving motor, in which a bearing housing is fixedly mounted to one side of a main body of the housing, a stopper is fixedly mounted to an exposed surface of the bearing housing, first and second sensors for sensing the access state of the arm during rotation of the arm are installed at one surface of the housing.
- the gear assembly includes an idle gear that is engaged with a spur gear mounted to the driving motor, a worm wheel for pivoting the arm by engaging with the arm, a worm for rotating the worm wheel, and a worm shaft having a spur gear at its one end, in which the worm is sliderably mounted to the worm shaft.
- the worm shaft is provided with a staged portion, which is formed at a position spaced from the one end of the worm shaft toward the other end thereof at a predetermined distance, in which a flange is formed at the other end of the worm shaft.
- the worm is sliderably mounted between the staged portion and the flange of the worm shaft, in which an elastic member for elastically supporting the worm is disposed between the worm and the flange of the worm shaft so as to restrain the slide movement of the worm.
- the touch sensor is mounted to a distal end of the arm, a camshaft is fixedly installed at a radial outer circumferential surface of the arm.
- the main body of the housing is fixed to one side of the headstock of the computerized numerically controlled lathe. The worm and the worm wheel engaged with the worm are rotated together until the camshaft of the arm is contacted with the stopper and then the arm reaches a predetermined sensing position.
- the cutting tool When the arm rotates and thereby it reaches the predetermined sensing position, the cutting tool begins to be moved on a basis of the pre-programmed process condition and then it is contacted with the touch sensor, whereby the touch sensor generates a sensing signal and then it supplies the control part of the computerized numerically controlled lathe with the sensing signal. If the camshaft provided at the arm reaches to the stopper, the worm wheel could't be further rotated and stops rotating. Under this state, if the driving motor operates for a predetermined time, the worm shaft continuously rotates. At this time, the worm engaged with the worm wheel stopped is rotated and moved in the axial direction of the worm shaft.
- the other end of the worm is spaced from the staged portion of the worm shaft at a predetermined distance and thereby compressing the elastic member. If the driving motor stops operating, the elastic force of the elastic member begins to be applied to the worm. At this time, a force may be applied to the worm wheel engaged with the worm in the clockwise direction. Although the driving motor stops operating, the camshaft of the rotating arm is continuously contacted with the stopper and thereby the touch sensor provided at the arm is fixed at the sensing position.
- the arm which has been reached at the sensing position in order to sense the front distal end of the cutting tool mounted to the tool rest in the computerized numerically controlled lathe, can be fixed at the sensing position due to the operation of the elastic member disposed between the worm and the flange of the worm shaft while the driving motor stops operating. Accordingly, it is possible to effectively prevent over-load operation of the driving motor and to prevent the driving motor from being damaged due to the over load. Thereby, the durability of the apparatus for automatically detecting the position of the cutting tool can be highly enhanced.
