Description
Technical field
The present invention relates to a kind of machine safety system, is a kind of system that the class machine tool strengthens security performance that is used for dashing, pressing, cut, cut specifically.
Background technology
The class lathe that dashes, presses, cuts, cuts that tradition is used does not all have safety device, often causes security incident because of machine failure or human error, causes personal injury, can't guarantee safe production.The junior machine safety device divides two classes at present: a class is the improvement on original lathe clutch, as the patent No. is 90223050.6 disclosed punching press value for shearing machine-tools safety controls, adopt the positive stop and the backstop of dual block to have preceding breach and back breach, preceding breach and the mutual staggered positions of back breach, malfunctioning at control device because of a variety of causes transmission, when block can not reset, this device can make lathe idle running automatically, do not make lathe " interlock " phenomenon that meets accident, thereby fundamentally stopping industrial accident malfunctioning because of control device or that break down and take place, its deficiency is not in machine tool running safeguard protection in the time of only judging machine failure, whether safety is not with dangerous from fact discerning, and can not stop personal injury accident to take place; Another kind of is to set up induction installation on original lathe; running and shutdown by induction installation control lathe; this device can be sensed at the lathe induction installation and close the lathe switch when person is in the lathe working hole automatically to prevent unexpected the generation; its weak point is: in the machine tool running; the person is in the lathe working hole suddenly, even if close the machine tool running switch this moment, because the work inertia of big machinery structure is bigger; still cause personal injury easily, mechanism's safety coefficient is lower.
Summary of the invention
To dash, press, cut, cut the class lathe and can't prevent effectively that personal injury accident from taking place in order to solve in the prior art, the low deficiency that waits of security performance, the purpose of this invention is to provide a kind of simple in structurely, can prevent effectively that personal injury accident from taking place, the safety enhancing system of machine tool that security performance is high
In order to achieve the above object, the technical solution used in the present invention is: a kind of safety enhancing system of machine tool, mainly comprise work top, lathe pedal and working head, working head main shaft one end connects by the work drive motor driving wheel driven through the clutch arm, the main shaft other end is provided with brake gear, brake gear is stopped for the internal expansion type hub, and its technical characterstic is that described work top is provided with first inductor, and first inductor is a photoelectric sensor; Described lathe pedal is provided with second inductor, and the lathe pedal has the holdout device by the prevention pedal depression of second inductor control; The stop position of described clutch arm is provided with the 3rd inductor, and the working head main shaft is provided with the brake apparatus by the braking spindle operation of the 3rd inductor control, and the internal expansion type hub is stopped and is connected with the 3rd inductor; Described first inductor connects second inductor and the 3rd inductor respectively and controls by the PLC control system.In the person is in the surveyed area of work top first inductor, first inductor sends danger signal to the PLC control system, this moment, operating personnel stepped on motivation bed pedal startup lathe, the second inductor induced signal sends closed working signal to the PLC control system, the PLC control system receives first and second inductor signal and controls holdout device and stops the lathe pedal to depress, and lathe is not worked; When machine tool running, the person is in the surveyed area of work top first inductor, first inductor sends danger signal to the PLC control system, the 3rd inductor of clutch arm stop position is responded to lathe driving wheel work and is sent the lathe working signal to the PLC control system, the PLC control system receives first, three inductor signals are also controlled brake apparatus braking spindle operation and the brake of control main shaft internal expansion type hub, lathe stops in emergency, no matter whether lathe starts shooting, safety enhancing system of machine tool all can detect and the security control lathe in real time, avoid contingency that the security performance height takes place.
Further, described holdout device comprises to be inhaled the iron switch and stops bar, inhales the iron switch and is connected with the PLC control system, stops the bar external part to be located at lathe pedal below, stop bar other end hinged lever, inhale iron switch adhesive lever and make and stop bar to extend lathe pedal below to stop the lathe pedal descending.The PLC control system receives the second sensor sensing signal controlling and inhales the work of iron switch, inhales moving bar one end that stops of iron switch suction, stops the bar rotation to make the prevention bar other end extend lathe pedal below and stops the lathe pedal descending.
Again further, described brake apparatus comprises inhales iron switch, brake block, clutch arm and clutch cover, inhaling the iron switch is connected with the PLC control system, clutch cover is placed on the working head main shaft and with the clutch arm and is contact condition, brake block is located at the clutch cover outer rim, inhales the iron switch adhesive brake block tight clutch cover of stopping and makes the clutch arm oppositely throw off driving wheel.The PLC control system receives the 3rd sensor sensing signal controlling and inhales the work of iron switch, inhale the iron switch and inhale moving brake block, because during the lathe operate as normal, the clutch arm of machine tool chief axis and driving wheel drives the clutch cover running, the brake block tight clutch cover of stopping, clutch arm antiport breaks away from machine tool chief axis and driving wheel, and main shaft is unpowered to shut down.
The invention has the beneficial effects as follows: when lathe was shut down, the person was in the lathe working hole, and controlling the lathe pedal jointly by first and second inductor can't depress, and lathe does not start; During lathe work; the person enters the lathe working hole; by the first and third inductor snub machine tool chief axis of controlling jointly that machine tool chief axis and driving wheel break away from and control internal expansion type hub is stopped; the lathe working head stops; this safety enhancing system of machine tool overall structure is simple; can shut down, start shooting at lathe and effectively prevent that personal injury accident from the security performance height taking place in the course of work.
The present invention sets up inductor on the driving wheel at lathe pedal, main shaft two ends; cooperate platen face inductor to control lathe pedal, lathe driving wheel, machine tool chief axis brake gear jointly; make lathe do not turn round or operation process in all can stop in real time; comprehensive safeguard protection; the safety coefficient height, safe in utilization.
