Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of drilling tapping machine, particularly a kind of tapping control apparatus of drilling tapping machine.
Background technology
Drilling tapping machine is for holing and the plant equipment of tapping, rotates boring or tapping on workpiece by carry its tools.
Tapping is to make internal thread, when tapping starts, needs often to carry out hard waste operation, particularly runs into when attacking obstructed screw, the chip in frequent hard waste evacuation aperture.When tapping, cutter needs to rotate forward, and hard waste is that cutter needs reversion.
Current drilling tapping machine is all rotated forward by driven by motor main shaft or reverses, thus control the rotation of cutter tapping or hard waste, current drilling tapping machine adopts the mode of manual operation button to control the rotation direction of motor, such as, control motor by pedal; Inconvenient operation by this method, need when particularly tapping starts to make cutter shoot workpiece by turning handle seat to cutter pressurization, hold very much appearance when needing in the process to move back thread and move back silk to controlling motor reversal while cutter pressurization again, cutter and the form of thread is caused to be damaged, operator is required too high, hard waste at any time cannot be accomplished.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of tapping control apparatus of drilling tapping machine, and the technical problem that the utility model solves is can hard waste at any time when tapping.
The purpose of this utility model realizes by following technical proposal:
A kind of tapping control apparatus of drilling tapping machine, drilling tapping machine comprises cabinet and is rotatably connected on the main shaft on cabinet, described cabinet is also provided with the gear shaft that main shaft can be driven to move along its axis, one end that gear shaft passes cabinet is traversing through end, it is characterized in that, this control device comprises the calibration disc be enclosed within traversing through end, described calibration disc rotates along with traversing through end and can rotate by opposed gear axle when being subject to circumferential resistance, the outer peripheral face of described calibration disc is fixed with stroke dog one, described cabinet is provided with the microswitch that can control main shaft rotating, when described calibration disc rotates stroke dog one can with microswitch against or depart from, be provided with between described calibration disc and cabinet can microswitch and stroke dog one against or microswitch depart from the position limiting structure that stroke dog makes calibration disc opposed gear axle rotate for the moment.
Spindle jacket has sleeve, and main shaft and quill are to fixed axis to being rotationally connected, and have tooth bar outside sleeve, gear shaft engages with tooth bar, can drive main shaft upwards or move down by turning gear wheel shaft, realizes boring and tapping, and by driven by motor, it rotates main shaft.
Its principle is as follows: microswitch is connected with motor, and realize by the rotating controlling motor the rotating controlling main shaft, when microswitch triggers, motor reversal is hard waste, and when microswitch does not trigger, motor just transfers tapping to; When main shaft is positioned at initial position, stroke dog one and microswitch against, when opening motor, because microswitch is in trigger state, motor reversal; When entering tapping, turning gear wheel shaft makes main shaft move down, calibration disc makes stroke dog one and microswitch depart from along with gear shaft rotates, microswitch is in non-toggle state, motor rotates forward, cutter carries out tapping, when microswitch and stroke dog one depart from, position limiting structure makes calibration disc opposed gear axle rotate, and stops calibration disc to rotate along with gear shaft, make stroke dog on calibration disc one and microswitch keeps both firm relative position when departing from; When completing tapping and needing hard waste, counter gear axle makes gear shaft drive main shaft to move up to be exited by cutter, when counter gear axle, calibration disc can rotate along with gear shaft, stroke dog one reverse time and microswitch against triggering microswitch, thus make motor reversal, cutter is reversed and realizes hard waste, stroke dog one and microswitch against time position limiting structure calibration disc opposed gear axle is rotated, stop calibration disc to rotate along with gear shaft, make stroke dog on calibration disc one and microswitch keeps both firm against time relative position; By position limiting structure make stroke dog once with microswitch against or depart from position time prevent calibration disc from rotating along with gear shaft, therefore the direction by controlling turning gear wheel shaft just synchronously can realize the forward or reverse controlling motor, directly just hard waste can be realized by counter gear axle after tapping completes, easy to operate, add security, avoid the damage of cutter.
In the tapping control apparatus of above-mentioned drilling tapping machine, described position limiting structure comprises spacer pin, described spacer pin is fixed on calibration disc, described cabinet has stroke limit hole, one end of described spacer pin is through stroke limit hole, described spacer pin can along with gear shaft rotates in stroke limit hole, microswitch and stroke dog one against time spacer pin and stroke limit hole side hole wall against, microswitch depart from stroke dog for the moment spacer pin and stroke limit hole opposite side hole wall against.The radian of spacer pin along with gear shaft rotation is defined by stroke limit hole, also just define the radian that calibration disc can rotate along with gear shaft, thus realize microswitch and stroke dog one against time or microswitch depart from stroke dog and to prevent a period of time calibration disc from rotating along with gear shaft.
