Abstract
The invention relates to a permanent magnet synchronous motor with a self-locking pressing protection encoder cover. The permanent magnet synchronous motor comprises a motor shell, a magnetic encoder is disposed in the motor shell, the motor shell is provided with the encoding protection cover, the encoding protection cover is fixed through self-locking pressing members, and then the encoding protection cover and the outer end face of the motor shell are on the same plane; and each self-locking pressing member comprises a concave hole, a clamping hook and a pressing head, each self-locking pressing member passes through the encoding protection cover and is clamped and fixed to the motor shell through the corresponding clamping hook, each pressing head tightly presses the end face of the encoding protection cover, and the middle of each clamping hook is provided with the corresponding concave hole. The permanent magnet synchronous motor is advantageous in that connection, fixing and sealing between the encoding protection cover and the motor shell are achieved through the self-locking pressing members in one time. Screws are not used to press a specially-produced encoder protection cover with a self-locking pressing member protection encoder cover and an elastic material self-locking pressing member; and, once the connection, fixing and sealing between the encoding protection cover and the motor shell are completed, only professionals of professional manufacturers can open the motor shell, and a role in protection of accuracy and precision of a magnetic induction encoder is played well.
Description
Technical field
The present invention relates to the permagnetic synchronous motor field of band magnetic induction encoder, particularly relate to a kind of permagnetic synchronous motor compressing protection encoder lid with self-locking.
Background technology
The permanent-magnet synchronous door motor of current band magnetic induction encoder and stepping motor.The command signal that the frequency converter that main dependence is accepted by magnetic induction encoder provides, make the action starting and rotate, therefore, magnetic induction encoder is motor-driven core component, Installation and Debugging due to magnetic induction encoder must be the precision requirements relying on the human users of specialty just can reach use, so magnetic induction encoder is once after Installation and Debugging, layman cannot make arbitrary change and debugging.The magnetic induction encoder protection of current permanent-magnet synchronous door motor relies on the mode of screw in compression encoder over cap to protect.Non-professional personnel are easy to just to open magnetic induction encoder over cap, easily because of dismounting, change magnetic induction encoder and cause the operation of motor to lose precision.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, and provide a kind of permagnetic synchronous motor compressing protection encoder lid with self-locking, is that one does not use screw in compression, and band self-locking compresses the permagnetic synchronous motor protecting encoder lid.
The object of the invention is to have come by following technical solution.This band self-locking compresses the permagnetic synchronous motor of protection encoder lid, comprise motor case, be provided with magnetic coder in described motor case, motor case be provided with coding protection lid and fixed by self-locking compressing member and the outer face making coding protection lid and motor case at grade; Described self-locking compressing member comprises shrinkage pool, grab and hold-down head, and self-locking compressing member is through coding protection lid and by grab fixing on motor case, hold-down head is pressed on the end face of coding protection lid, has shrinkage pool in the centre of grab.
Described self-locking compressing member is made up of elastomeric material, and multiple self-locking compressing member is passed coding protection lid and fixed on motor case by grab.
Beneficial effect of the present invention is: to be disposablely connected to a fixed sealing by self-locking compressing member and motor case.Screw in compression band self-locking compressing member is not used to protect special encoder protective cover and the elastomeric material self-locking compressing member of encoder lid; once after being connected and fixed good seal with the casing of motor; except the professional of specialized factory can open; all other men person uses specific purpose tool without training, forever cannot open when not damaging encoder protective cover.Well serve the effect of protection magnetic induction encoder precision.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present invention.
Fig. 2 is the structural representation of 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, coding protection lid 3, magnetic coder 4.
Embodiment
Below in conjunction with accompanying drawing, detailed introduction is done to the present invention:
As shown in the figure, this band self-locking compresses the permagnetic synchronous motor of protection encoder lid, comprise motor case 1, be provided with magnetic coder 4 in described motor case 1, motor case 1 be provided with coding protection lid 3 and fixed by self-locking compressing member 2 and the outer face making coding protection lid 3 and motor case 1 at grade; Described self-locking compressing member 2 comprises shrinkage pool 2-1, grab 2-2 and hold-down head 2-3; self-locking compressing member 2 is made up of elastomeric material; multiple self-locking compressing member 2 is also fixed on motor case 1 by grab 2-2 through coding protection lid 3; hold-down head 2-3 is pressed on the end face of coding protection lid 3, has shrinkage pool 2-1 in the centre of grab 2-2.
After the Installation and Debugging of magnetic induction encoder complete, use encoder over cap and elastomeric material to make self-locking compressing member, fixing by the self-locking mechanism sealing that to be connected with motor case.The industry librarian use specific purpose tool of specialized factory can be opened when not destroying encoder protective cover.
The present invention is not limited to above-mentioned execution mode, no matter do any change, every employing structural design provided by the present invention on its shape or material are formed, is all one distortion of the present invention, all should thinks within scope.
