Described mould also comprises Fibre Optical Sensor, reverses until tooth core resets to the Programmable Logic Controller of start bit for the optical signal control motor that detects induction groove according to this Fibre Optical Sensor, and described travelling gear is provided with induction groove; When start bit, Fibre Optical Sensor is corresponding with induction groove, and it is corresponding once with induction groove that travelling gear often revolves the Fibre Optical Sensor that turns around.
Wherein, described tooth core is provided with the locating slot of locating initial tooth when installing.
Wherein, comprise the tooth core gear of at least two tooth cores and respective amount, each tooth core gear all engages with travelling gear.
Wherein, motor connects master gear by shaft coupling.
Wherein, comprise two tooth cores and two tooth core gears, two tooth core gears are symmetrically set in the both sides of travelling gear.
Implement the embodiment of the present invention, there is following beneficial effect:
The embodiment of the present invention is by being equipped with fiber sensor, Programmable Logic Controller PLC, motor, when installing, only need install by designing in advance orientation by mould, motor return initial point is determined with induction groove, PLC by inductor, no matter motor rotates how many circles initial point that finally all can playback thus, and thread start bit can not be become all the time.Thread starting point of the present invention automatically resets, and to have changed reset by the mould of machinery location thread start bit inaccurate and need the frequent deficiency of adjusting for mould, can accurately locate aborning thread original position, as long as after mould assembles by positioning requirements, without adjusting again, effectively meet the need of production that thread start bit is required to high meticulous thread product.By thread starting point of the present invention automatically reset mould greatly saved mould produce in time cost and personnel cost.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing described below is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of a kind of hinge tooth mould that can parking position accuracy thread starting point of the embodiment of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing of the present invention, technical scheme in the embodiment of the present invention is carried out to clear, complete description, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work, belongs to the scope of protection of the invention.
In conjunction with Fig. 1, a kind of hinge tooth mould that can parking position accuracy thread starting point of the embodiment of the present invention is described.As shown in Figure 1, hinge tooth mould in the present embodiment comprises: motor 5, master gear 4, travelling gear 3, tooth core gear 2 and tooth core 1, also comprise Fibre Optical Sensor 6 and reverse until tooth core 1 resets to the Programmable Logic Controller of start bit for the optical signal control motor 5 that detects induction groove according to this Fibre Optical Sensor 6.Wherein the function of each several part is as shown in the table:
| Title | Function |
| Tooth core | Shaped article tooth position |
| Tooth core gear | Rotarily driving tooth core rotates |
| Travelling gear | Drive tooth core gear to rotate, and locate tooth turned position |
| Master gear | The output of revolution power |
| Motor | The rotation of outputting power control master gear |
| Fibre Optical Sensor | The induction of tooth turned position |
The core of tooth described in the present embodiment 1 is provided with the locating slot of locating initial tooth when installing, described tooth core gear 2 is for driving tooth core 1 to rotate, tooth core gear 2 is fixed on tooth core 1 periphery, and travelling gear 3 engages with master gear 4 and tooth core gear 2 between master gear 4 and tooth core gear 2 and respectively.When work, motor 5 rotates and drives master gear 4 to rotate, and master gear 4 drives tooth core gear 2 to rotate by travelling gear 3, and tooth core gear 2 drives tooth core 1 to rotate so that the moulding of product thread forms the internal thread corresponding with the thread of tooth core 1 on product.
Further, hinge tooth mould in the present embodiment is provided with corresponding induction groove at travelling gear 3, and when initial installation, Fibre Optical Sensor 6 is corresponding with induction groove, it is corresponding once with induction groove that travelling gear 3 often revolves the Fibre Optical Sensor 6 that turns around, therefore can know the number of turns that travelling gear 3 rotates; When forward rotation, Fibre Optical Sensor 6 is known the travelling gear 3 forward rotation number of turns by induction groove, and then CD-ROM drive motor rotates backward this number of turns starting point that can playback.During due to start bit, Fibre Optical Sensor 6 is corresponding with induction groove, even inadequate one week of travelling gear 3 forward rotation, when travelling gear 3 rotates backward, Fibre Optical Sensor 6 illustrates and turned back to original point when corresponding with induction groove.Specific implementation can be: when initial, Programmable Logic Controller is counted as 0, when motor forward rotation, it is corresponding once with induction groove that travelling gear 3 is often rotated in the forward a circle Fibre Optical Sensor 6, corresponding Programmable Logic Controller can once be counted and add 1, in the time that needs reset, controlling motor rotates backward, it is also corresponding once with induction groove that Fibre Optical Sensor 6 is enclosed in the every reverse rotation one of travelling gear 3, corresponding Programmable Logic Controller can once be counted and subtract 1, in the time that equaling 0, the counting of Programmable Logic Controller automatically controls motor power-off, now motor parking position accuracy.
Preferably, can comprise the tooth core gear 2 of at least two tooth cores 1 and respective amount in described hinge tooth mould, each tooth core gear 2 all engages with travelling gear 3.To improve product thread shaping efficiency.The present embodiment comprises that two tooth cores 1 and 2, two tooth core gears 2 of two tooth core gears are symmetrically set in the both sides of travelling gear 3, with stress equalization.
Preferably, in this enforcement, motor connects master gear 4 by shaft coupling, and described travelling gear 3 is 2～4:1 with the teeth quantity ratio of tooth core gear 2.
By the hinge tooth mould of the embodiment of the present invention, when installing, only need install by designing in advance orientation by mould, motor return starting point is determined by Fibre Optical Sensor, induction groove, PLC, no matter motor rotates how many circles starting point that finally all can accurately playback thus, and thread start bit can not become all the time like this.Change traditional hinge tooth mould by the inaccurate of machinery location thread start bit and needed the frequent deficiency of adjusting by hinge tooth mould of the present invention, effectively meet thread starting point is resetted and requires high meticulous thread production needs, greatly saved time and cost of labor in mould production.
Above disclosed is only preferred embodiment of the present invention, certainly can not limit with this claim scope of the present invention, therefore, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., still belong to the scope that the present invention is contained.
