Abstract

The invention relates to a high-sensitivity high-reliability clutch for a pressing machine and a clutch control method. At the moment that hands of an operator pass through an optical inductor and enter a dangerous area, the optical inductor commands a trigger mechanism to act to make an contact of the trigger mechanism retract; a ratchet head in an actuating mechanism is engaged with a ratchet tooth groove under the action of a tension spring and a ratchet wheel is in braking state; the ratchet wheel makes counterforce acted on the ratchet head act on a vector damping buffer mechanism; the vector damping buffer mechanism releases the absorbed counterforce and makes the counterforce act on the ratchet wheel through the ratchet head, so that an operating key is separated from a crank shaft instantly and the crank shaft stops rotating; when the danger is eliminated, a button is opened; when the release mechanism pulls the ratchet head to separate from the ratchet wheel, the contact of the trigger mechanism extends out and the ratchet head is lapped on the contact, the operating key is acted by shearing force again so that a clutch is positioned in a closed position.

(the woodpecker head of ratchet head in the actuator; be called for short the sour jujube head) cooperate with vector damping buffering mechanism: after the trigger mechanism action; ratchet head is under the effect of draught spring; afterbody by ratchet head has locating stud; play and to rotate according to the center of pin by finger setting; this moment, ratchet head was under the effect of spring force; ratchet head will be by the spring force direction; be that the center is done spacing and rotatablely moved with the bearing pin; make ratchet head and ratchet teeth portion (teeth groove) engagement; owing to have a certain amount of dynamic load energy during the ratchet rotation; to produce relative energy after the engagement and discharge impact force; the vector damping buffering mechanism of this moment weakens the impact force alleviation; until stopping; utilize the bounce-back of spring force then; promote in the opposite direction by the first ratchet of sour jujube; cause ratchet and job key to break away from fast, promptly quit work, played the effect of safety protection.

Releasing mechanism: after eliminating danger, lathe is provided with very start button, after confirming safety, press very start button, releasing mechanism work is pulled out ratchet head in the ratchet teeth groove, and delivers to the trigger mechanism place and block locking, so that next triggering work, trigger mechanism this moment warming-up exercise at any time.Meanwhile, ratchet has obtained release.Because the flywheel of lathe is rotatablely moving down in working order, so ratchet will do the rotation that resets under the effect of draught spring, and the key that ratchet has driven work rotates, and lathe is worked normally, the release that resets after promptly having realized protecting.

Trigger mechanism: trigger mechanism adopts reliable in quality, agile electromagnet, with safety action fast, accurately.Parts such as contact adopt superior alloy steel (strengthening rigidity and abrasion resistance), and select for use the high-quality spring as Returnning spring, guarantee to reset and put in place, adopt the oilless bearing alloy between them, put and have die casting graphite, guarantee not have the appearance of jam phenomenon, make the action success rate reach 100%.

Its working principle: with reference to accompanying drawing 1.In lathe work; utilize light curtain protector; as the first reflection safety operation parts; when operator's hand enters the deathtrap (when the slide block working area puts in; the speed that hand moves is 1.2 seconds/meter) time; light is admired inductor and is sent stop signal; again this signal is become electrical signal; trigger trigger mechanism work by amplifying, trigger mechanism is received the moment of instruction contact is withdrawn, and makes ratchet mechanism do the spacing rotation; figure F2 is for being subjected to force direction (moving right); impel ratchet head (woodpecker head) under the effect of drawing spring force F3, do spacing and rotatablely move, F4 will do clockwise motion; ratchet head is rotated downwards; and with ratchet teeth portion engagement, be in self-locking state, F1 is stopped the rotation.Because F1 is in the process of rotation, be subjected to rotating force and The Effect of Inertia Force, when stopping, producing a certain amount of dynamic load and impact force, through the power after the engagement, will the power of ratchet whole pass to ratchet head (F6 is for being subjected to force direction), vector damping buffering mechanism will move and plant lotus impact force homenergic weakening decay, all energy with spring force compression to zero the time, quantitative power by spring discharges (F7 is a spring release force direction) again, this moment is under the effect of spring force, ratchet is promoted in the opposite direction (F1 will to moving clockwise) by ratchet head, impelled rotation rigidity job key and bent axle to break away from, make bent axle stop rotation, just stopped the motion of slide block.Meanwhile, braking mechanism will be done brake, and the inertial force that rotatablely moves is decayed as early as possible, stop with the fastest speed.In this a series of signal transduction process, the used time of implementation is 200 milliseconds, finish in about 0.2 second, add the rotation work key, about 10 degree of the angle of rotation, the distance that slide block moved normally is 6.1 millimeters, and ratchet is under the effect of spring force, and ratchet will move in the opposite direction, impel the rigidity job key to break away from faster, make the downward distance of slide block will be still less, about 5 millimeter, it is 0.05 second that this mechanism possesses the used time of damping buffer, be exactly 0.2+0.05=0.25 second so, slide block displacement distance is 4.5 millimeter, and when operator's hand also had 200 millimeters apart from slide block at this moment, slide block had just stopped work.Therefore, operator's hand has just obtained protection.Meanwhile, lathe is owing to be subjected under the effect of inertial force, and flywheel continues rotation, causes the rigidity job key to break away from, and that has realized promptly that slide block moves downward stops.Lathe is stopped by top dead center to being protected of lower dead center at work, plays the safety protection effect.After lathe stops, sending and stop alarm signal, the operator can judge the there very intuitively and report to the police according to the signal of being reported, and after clearing, can do release movement by dedicated button, and lathe is started once more.By restarting button, electrical signal is delivered to the execution releasing mechanism, move upward (F8 direction) by carrying out releasing mechanism (by middle lever, power is done reverse motions, or change the direction of power) pulling ratchet head, cause ratchet head to break away from the engagement of ratchet.Because lathe is under the state that stops, main motor continues in work, just flywheel is at rotation status, when pulling out ratchet head, ratchet is under the effect of draught spring, rotate, make the rotation of rigidity work turn key, this moment, job key began to be subjected to the effect of shearing force again, and the position that causes clutch to be in to close makes the bent axle of lathe continue rotation, the slide block of lathe begins new one and takes turns motion, nephew's lower dead center is finished its one action circulation to top dead center, arrives the back lathe and is in next readiness for operation again.

Use the material of ratchet unit to adopt high-quality alloy steel,,,, improve shear strength, increase hardness and abrasion resistance to strengthen fatigue resistance through modified, carburizing through the Overheating Treatment strict process control.Make the more evenly refinement of interior tissue of ratchet, sour jujube head, outer surface is more even, makes clutch more sturdy and durable, has prolonged its working life greatly.
