Abstract
The present invention relates to a kind of permagnetic synchronous motor that protection encoder cover is compressed with self-locking; including motor case; magnetic coder is provided with described motor case, motor case is provided with coding protection lid and is fixed by self-locking compressing member and causes the outer face of coding protection lid and motor case at grade；Described self-locking compressing member includes shrinkage pool, grab and hold-down head, and self-locking compressing member is fixed on motor case through coding protection lid and by grab, and hold-down head is pressed on the end face of coding protection lid, and shrinkage pool is provided with the centre of grab.Beneficial effects of the present invention are：It is disposable to be connected to a fixed sealing by self-locking compressing member and motor case.The special encoder protective cover and elastomeric material self-locking compressing member of encoder cover are protected with self-locking compressing member without using screw in compression; it is connected once the casing with motor after good seal; only the professional of specialized factory can be opened, and the effect of protection magnetic induction encoder precision is served well.
Description
Technical field
Protection is compressed the present invention relates to the permagnetic synchronous motor field with magnetic induction encoder, more particularly to a kind of band self-locking
The permagnetic synchronous motor of encoder cover.
Background technology
Current permanent-magnet synchronous door motor and stepper motor with magnetic induction encoder.Rely primarily on and connect by magnetic induction encoder
The command signal that the frequency converter received is provided, makes the action for starting rotation, therefore, magnetic induction encoder is motor-driven core
Part, because the installation and debugging of magnetic induction encoder must can just reach the precision used by the human users of specialty
It is required that, so magnetic induction encoder is once after installation and debugging, layman cannot make arbitrary change and debugging.Current
The magnetic induction encoder protection of permanent-magnet synchronous door motor is protected by the mode of screw in compression encoder protection cap.It is non-special
The personnel of industry are easy for that magnetic induction encoder protection cap can be opened, easily because of dismounting, change magnetic induction encoder and cause electricity
The operation of machine loses precision.
The content of the invention
It is an object of the invention to overcome the shortcomings of that prior art is present, and a kind of band self-locking is provided and compresses protection encoder
The permagnetic synchronous motor of lid, is a kind of without using screw in compression, the permagnetic synchronous motor of protection encoder cover is compressed with self-locking.
The purpose of the present invention is completed by following technical solution.It is this to compress protection encoder cover forever with self-locking
Magnetic coder is provided with magnetic-synchro motor, including motor case, described motor case, motor case is provided with coding protection
Cover and fixed by self-locking compressing member and cause the outer face of coding protection lid and motor case at grade；It is described from
Locking compressing member includes shrinkage pool, grab and hold-down head, and self-locking compressing member is fixed in motor machine through coding protection lid and by grab
On shell, hold-down head is pressed on the end face of coding protection lid, and shrinkage pool is provided with the centre of grab.
Described self-locking compressing member is made up of elastomeric material, and multiple self-locking compressing members are through coding protection lid and pass through grab
Fix on motor case.
Beneficial effects of the present invention are：It is disposable to be connected to a fixed sealing by self-locking compressing member and motor case.Do not make
The special encoder protective cover and elastomeric material self-locking compressing member of encoder cover are protected with self-locking compressing member with screw in compression, once
Be connected with the casing of motor after good seal, except the professional of specialized factory can open, all other men person without
Training uses specific purpose tool, can not be opened forever in the case where not damaging encoder protective cover.Serve protection magnetic well
The effect of induction encoder precision.
Brief description of the drawings
Fig. 1 is the main structure diagram of the present invention.
Fig. 2 is the structural representation of the self-locking compressing member of the present invention.
Label in accompanying drawing is respectively：Motor case 1, self-locking compressing member 2, shrinkage pool 2-1, grab 2-2, hold-down head 2-3 are compiled
Code protection cap 3, magnetic coder 4.
Embodiment
Detailed introduction is done to the present invention below in conjunction with accompanying drawing：
As illustrated, this permagnetic synchronous motor that protection encoder cover is compressed with self-locking, including motor case 1, it is described
Motor case 1 in be provided with magnetic coder 4, motor case 1 is fixed provided with coding protection lid 3 and by self-locking compressing member 2
And cause the outer face of coding protection lid 3 and motor case 1 at grade；Described self-locking compressing member 2 includes shrinkage pool 2-
1st, grab 2-2 and hold-down head 2-3, self-locking compressing member 2 is made up of elastomeric material, and multiple self-locking compressing members 2 pass through coding protection lid 3
And fixed by grab 2-2 on motor case 1, hold-down head 2-3 is pressed on the end face of coding protection lid 3, grab 2-2's
Centre is provided with shrinkage pool 2-1.
After the completion of magnetic induction encoder installation and debugging, the self-locking pressure being made using encoder protection cap and elastomeric material
Tight part, is connected to seal with motor case by self-locking mechanism and fixed.The industry librarian use specific purpose tool of specialized factory is not being broken
It can be opened in the case of bad encoder protective cover.
The present invention is not limited to the above-described embodiments, and any change is made no matter being constituted in its shape or material, every to adopt
Structure design provided by the present invention is used, is all a kind of deformation of the present invention, is considered as within the scope of the present invention.
