Abstract
The utility model relates to a disengaging mechanism for full-automatic spring coiling machine, which protects the elements against damaging and separates a main computer from a generator when the full-automatic spring coiling machine produces overload at extraordinary case. The utility model comprises a reduction box, a driving shaft, a clutch pressure plate and a driven plate, wherein the reduction box is connected with the driving shaft covered with a copper sleeve, the front driving shaft uses the screw and the dished spring to connect the clutch pressure plate and the driving shaft, the middle of the clutch pressure plate is negative and provided with a hole which is through the driven plate, a negative ring is around the hole, balls are in the negative ring, the driven plate and two frictional disks are installed in the dent of the clutch pressure plate, the two friction disks are on the two sides of the driven plate, one friction disk is applied to the driving shaft, the other friction disk is applied to the clutch pressure plate, and the driven plate has a convex area which projects from the clutch pressure plate and is connected with a carrier wheel driving the motor.
Description
Technical field:
The utility model relates to field of spring processing, relates to a kind of full automatic spring coiling machine and produces overload abnormal conditions occurring, the mechanism that main frame is separated with motor in order to protect its part not suffer damage.
Background technology:
Full automatic spring coiling machine is to produce a kind of equipment that is used for the biconial spring of sping mattress.This equipment is to take out by the spring that a manipulator is not tied a knot rolled two ends to deliver to knotting mechanism and tie a knot, and then will play the spring that finishes and deliver to heat treatment mechanism and heat-treat, at last with the spring marshalling.The running of equipment is at a high speed, might there be minor variations to cause camber of spring owing to roll the steel wire material of spring, also might be because the swing in motion at a high speed of the bullet that rolls out is too big, at manipulator spring is delivered to and to be had spring and do not deliver to position accurately accidentally when tiing a knot on the knotting bucket.At this moment the work of knotting bucket do as usual, when the mechanism of knotting barrel does not clip the spring of sending here, is easy to cause machine stuck.The part of part knotting very easily damages like this.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, provides a kind of main frame that can allow when above-mentioned situation occurring separate the overload protecting mechanism that is used for full automatic spring coiling machine that the damage that makes part reduces to minimum with motor.
For achieving the above object, the technical scheme that the utility model provides is: mainly include reduction box, driving shaft, clutch pressing disk, clutch plate, reduction box is connected with driving shaft, front end at driving shaft is connected clutch pressing disk with disk spring by bolt with driving shaft, the middle part of clutch pressing disk is recessed, and this one is provided with one can be by the hole of clutch plate, clutch plate and two friction plates are installed in the recess of clutch pressing disk, two friction plates place the both sides of clutch plate, a slice and driving shaft are fitted, another sheet and clutch pressing disk are fitted, and form projection on the clutch plate, and this high spot stretches out clutch pressing disk and connected one and drives the sprocket wheel that main frame turns round.
Be preset with a recessed circle around the hole of described clutch pressing disk recess, recessed circle includes puts ball; Be with copper sheathing on the axis body of driving shaft.When ball and copper sheathing had guaranteed that sprocket wheel 8 is subjected to radial pull, clutch plate and friction plate were stressed evenly.
After the utility model adopts technique scheme, when when the unsuccessful steel wire of machine knotting has blocked the part of knotting, producing bigger anti-torsion, disk spring forces clutch plate to continue to rotate with driving shaft to the pressure of clutch pressing disk inadequately, and friction plate and clutch plate produce slip.The transmission of main frame has separated with motor though motor still drives the driving shaft rotation, has so just protected the part of knotting can not be subjected to bigger damage.Allow main frame separate, make the damage of part reduce to minimum, reach the effect of protection part with motor.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
The specific embodiment:
See that shown in the accompanying drawing 1, preferred embodiment of the present utility model is as follows, reduction box 1 is connected with a driving shaft 2.Front end at driving shaft 2 is connected clutch pressing disk 3 with disk spring 5 by bolt with driving shaft 2.The middle part of clutch pressing disk 3 recessed and be provided with one can be by clutch plate 4 the hole.Around the hole a recessed circle is arranged again, be used to contain and put ball 6.Contain the both sides that two friction plates 7 and a clutch plate 4, two friction plates 7 place clutch plate 4 at the recess of clutch pressing disk 3, a slice and driving shaft 2 fit another sheets and clutch pressing disk 3 applyings.The high spot of clutch plate 4 stretches out clutch pressing disk 3 and has connected one by screw and drives the sprocket wheel 8 that main frame turns round.Ball 6 and the effect that is enclosed within the copper sheathing 9 on driving shaft 2 axis bodies are to prevent that sprocket wheel 8 from making clutch plate 4 and friction plate 7 unbalance stress when being subjected to radial pull.Utilize disk spring 5 can regulate the pressure of clutch pressing disk 3 by bolt, when machine during in operate as normal the pressure of clutch pressing disk 3 be adjusted to suitable just.Produced a big anti-torsion when the unsuccessful steel wire of machine knotting has blocked the part of knotting, the pressure of 5 pairs of clutch pressing disks 3 of disk spring forces clutch plate 4 to continue to rotate with driving shaft 2 inadequately.At this moment friction plate 7 produces with clutch plate 4 and slides.The transmission of main frame has separated with motor though motor still drives driving shaft 2 rotations, has so just protected the part of knotting can not be subjected to bigger damage.Can increase or reduce the limit torsion of apparatus overload protection by disk spring 5.
The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
