Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1, the utility model provides a kind of spiral shell lever fixing apparatus for TPR double screw extruder, including
It is directly socketed in the positioning chuck 1 of screw end, is installed between the other end and extrusion driving mechanism of the positioning chuck 1 useful
In the soft start type permanent magnet clutch 2 of transmitting kinetic energy；Screw rod is fixedly mounted with can be convenient in the positioning chuck 1, can also be square
Just disassembling section is carried out；The soft start type permanent magnet clutch 2 drives high-speed rotation by external motor, and then drives screw rod
The work such as Stirring are realized in device rotation.
It further illustrates, the positioning chuck 1 includes chuck main body 101, the lower surface pair of the chuck main body 101
Title is inlaid with mobilizable software claw 102, and the spiral fixation hole having for installing screw rod is dug at the center of chuck main body 101
103, it is connected between the software claw 102 and chuck main body 101 by self-locking spring 104；The software claw 102 is shared
Four, the front end of each claw, which is all provided with, is set to cambered surface identical with screw rod end curvature, and each cambered surface inner wall is dug and had
The threaded hole matched with screw rod end thread.
When needing to install screw rod, self-locking spring 104 is unclamped first, screw rod grafting is entered into chuck main body 101
Inside spiral fixation hole 103, software claw 102 is then tightly attached to screw surface, self-locking spring 104 is tightened and realizes fixed peace
Dress.
Supplementary explanation, the soft start type permanent magnet clutch 2 includes the linear axis being connected directly with positioning chuck 1
Hold seat 201, the center of the linear bearing seat 201 is inlaid with permanent magnet disc rotor 202, the permanent magnet disc rotor 202 it is another
One end is coupled with conductor disc rotor 203, and the appearance mask of the conductor disc rotor 203 and permanent magnet disc rotor 202 is connected to shaft coupling
The shaft of device protective shell 204, conductor disc rotor 203 is circumscribed with by connecting rod for driving the rotation of entire shaft coupling rotation to drive
Dynamic motor 205.
Preferably, altogether there are two being symmetrically installed, each permanent magnet disc rotor 202 includes the permanent magnet disc rotor 202
The fixation connecting rod 206 being plugged in linear bearing seat 201 is socketed with rotation aluminium dish 207 on the fixed connecting rod 206 from beginning to end；Institute
It states and is inlaid with permanent magnet 208 on rotation 207 opposite face of aluminium dish, rotation aluminium dish 207 and the contact surface up and down of fixed connecting rod 206 are equal
Limited block 209 is installed；The rotation aluminium dish 207 is the carrier of permanent magnet 208, sense of the permanent magnet 208 in conductor disc rotor 203
It should descend to relatively rotate, and then drive the positioning chuck 1 of lower section and screw rod rotation, limited block 209 that permanent magnet can be effectively prevented
Disc rotor 202 exceeds the position of fixed connecting rod 206.
In the present embodiment, the conductor disc rotor 203 includes iron pan carrier 210 made of pure iron, the iron pan carrier
210 inner ring is inlaid with the rotation copper dish 211 for cutting magnetic induction line；Wherein, rotation copper dish 211 are that main cutting magnetic induction is answered
The torque transmitter of line generation eddy current；Iron pan carrier 210 as rotation copper dish 211 carrier, role be with forever
The suction of magnet disc rotor 202 keeps suitable gap, it is made to transmit torque jointly, and is the axial direction of permanent magnet disc rotor 202
Movement provides enough spaces.
Conductor disc rotor 203 is active part, and permanent magnet disc rotor 202 is secondary part.When motor drives conductor disc to turn
When son 203, moment reaches high speed, and 202 speed of permanent magnet disc rotor is lower, rotates the repulsion between copper dish 211 and permanent magnet 208
Greater than the attraction between iron pan carrier 210 and permanent magnet 208, such two symmetrical permanent magnet disc rotor 202 is adjacent to, rotation
Air gap between copper dish 211 and permanent magnet 208 becomes larger；When rotational speed difference reaches biggish value, sufficiently large torque could be transmitted,
Repulsion is also larger；It is on the contrary then opposite.
Just when starting permanent magnet disc rotor 202 accelerate it is slower, as 202 speed of permanent magnet disc rotor becomes larger, rotational speed difference compared with
Small, generated repulsion is smaller, when repulsion is less than the attraction of iron pan carrier 210 and permanent magnet disc rotor 202, two permanent magnetism
Body disc rotor 202 separates, and the air gap between rotation copper dish 211 and permanent magnet disc rotor 202 becomes smaller in this way, and lesser rotational speed difference is
Torque required for driven shaft can be provided, after air gap reaches scheduled position, after accelerating to the speed of requirement, i.e., opened completely
It is dynamic；First closing separates permanent magnet disc rotor 202 outward again inwards, which can realize that the soft of rotary drive motor 205 is opened
It is dynamic；And in the general course of work, since emergency case causes driven shaft to block or load excessive suddenly, rotational speed difference is i.e. prominent
It so increases, the repulsion between rotation copper dish 211 and permanent magnet disc rotor 202 increases in this way, is greater than iron pan carrier 210 and permanent magnet
The attraction of disc rotor 202, two permanent magnet disc rotors 202 quickly close up, and the torque of transmitting reduces, to reach protection rotation
The purpose of driving motor 205.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new
The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing for the equivalent requirements of the claims will be fallen in
All changes in justice and range are embraced therein.It should not treat any reference in the claims as limiting
Related claim.
