Abstract
The utility model relates to a locked-rotor detecting device of a spiral chip removal machine for a numerical control machine tool, which belongs to the field of machine tools. The locked-rotor detecting device is provided with a rotating shaft, the rotating shaft is connected with a motor via a coupler and provided with spiral blades, the locked-rotor detecting device is characterized in that a plurality of iron induction plates are mounted on a peripheral surface of the rotating shaft, and an approach switch is mounted on the outer side of each iron induction plate via an approach switch support. The locked-rotor detecting device is simple in structure, acquires rotating signals of the rotating shaft via a programmable logic controller, and judges whether the chip removal machine operates or not via a system, is located in a positive rotation state or a negative rotation state and is in locked-rotor or not.
Description
Technical field
The utility model relates to machine tool field, at length says it is the rotation-blocking up detection device of a kind of Digit Control Machine Tool with the spiral Scrap-removing machine.
Background technology
As everyone knows, the Digit Control Machine Tool of machine-tool industry can be realized the execution of automatic processing program, but in a single day the stall problem appears in the spiral Scrap-removing machine of its accessory kit, just need manually carry out Scrap-removing machine rotating operation.Existing spiral Scrap-removing machine is operated great majority and is adopted open loop control, drives the helical axis that has helical blade by reductor, and the promotion material is (backward) forward, concentrates on discharging opening, falls into assigned address.Be mainly used in the less lathe in chip removal space (as the numerical control machining center etc.), its control generally all is (starting or stoping by procedure) or manually control automatically, and open loop approach does not have feedback.Start Scrap-removing machine in case large tracts of land smear metal accumulation back occurs, helical blade very easily occurs and stop up, cause drive motor to rotate, the thermel protection device take-off plays a protective role behind the electric current overrate.But it is often excessive because of electric current; occur thermel protection device easily and do not move the catastrophe failure that drive motor just burnt as yet; perhaps reset and protection device behind the stall needs by hand the spiral Scrap-removing machine to be carried out repeatedly rotating operation and can remove blockage problem, even need manually clear up.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides the rotation-blocking up detection device of a kind of Digit Control Machine Tool with the spiral Scrap-removing machine, gather the turn signal of rotating shaft by programmable logic controller (PLC), and judge by system whether Scrap-removing machine moves, present positive-negative rotation state and stall whether.After the Scrap-removing machine operation, a period of time is detected the signal less than sensing chip, promptly be judged as the stall state, program by design in advance switches to the direction of rotation of Scrap-removing machine on the contrary automatically, detect induced signal once more, after detecting two above sensing chip signals, system is judged as counter-rotating and has dredged obstruction, thereby automatically switches to predetermined positive revolving die formula.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of Digit Control Machine Tool rotation-blocking up detection device of spiral Scrap-removing machine, be provided with rotating shaft, rotating shaft links to each other with motor through shaft coupling, helical blade is installed in the rotating shaft, it is characterized in that on the periphery of rotating shaft a plurality of irony sensing chips being installed, the irony sensing chip outside is through being equipped with one near switch near switch bracket.
The beneficial effects of the utility model are, and are simple in structure, gather the turn signal of rotating shaft by programmable logic controller (PLC), and judge by system whether Scrap-removing machine moves, present positive-negative rotation state and stall whether.After the Scrap-removing machine operation, a period of time is detected the signal less than sensing chip, promptly be judged as the stall state, program by design in advance switches to the direction of rotation of Scrap-removing machine on the contrary automatically, detect induced signal once more, after detecting two above sensing chip signals, system is judged as counter-rotating and has dredged obstruction, thereby automatically switches to predetermined positive revolving die formula.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model, also is the structural representation of a kind of embodiment.
1. helical blades among the figure, 2. rotating shaft, 3. irony sensing chip, 4. near switch bracket, 5. near switch, 6. shaft coupling, 7. motor.
The specific embodiment
In Fig. 1, the utility model is provided with rotating shaft 2, rotating shaft 2 links to each other with motor 7 through shaft coupling 6, helical blade 1 is installed in the rotating shaft 2, a plurality of irony sensing chips 3 are installed on the periphery of rotating shaft 2, irony sensing chip 3 generally is no less than 6, quantity is many more, accuracy of detection is high more, irony sensing chip 3 outsides are through being equipped with one near switch 5 near switch bracket 4, near switch bracket 4 and can carry out the position adjustment within the specific limits, thereby adjust irony sensing chip 3 and near the distance between the switch 5 near switch 5.
The utility model the spiral Scrap-removing machine rotating shaft 2 peripheries a plurality of irony sensing chips 3 are installed, employing detects the signal of irony sensing chip near switch 5, gather this signal by the programmable logic controller (PLC) of digital control system, and judge by system whether Scrap-removing machine moves, present positive-negative rotation state and stall etc. whether.After the Scrap-removing machine operation, a period of time is detected the signal less than irony sensing chip 3, promptly be judged as the stall state, program by design in advance switches to the direction of rotation of Scrap-removing machine on the contrary automatically, detect induced signal once more, after detecting two above irony sensing chip 3 signals, system is judged as counter-rotating and has dredged obstruction, thereby automatically switch to predetermined positive revolving die formula, this circulation can be set positive and negative number of times as required, still detect less than the sensing chip signal then be judged to be serious obstruction if surpass setting value, stop procedure and the alarm picture of design occurs.
