Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

In order to better understand the technical scheme of the present application, the following detailed description is provided for the person skilled in the art with reference to the accompanying drawings and the detailed description.

As shown in fig. 1 to 5, in the present embodiment, a servo motor structure with a manual release function is provided, which includes a servo motor 1 and a brake 2, a first release hole 24 is provided on an end face of the brake 2 facing away from the servo motor 1, and specifically, the first release hole 24 penetrates through the brake 2 and an armature 23; the periphery of the brake 2 is sleeved with a brake cover 3, a second release hole 31 corresponding to the first release hole 24 is formed in the end face of the brake cover 3, a release piece 4 is arranged in the second release hole 31, and the release piece 4 extends into the first release hole 24 and is used for separating the brake disc 22 and the armature 23 in the brake 2.

As shown in fig. 1, in the above embodiment, the present application realizes the temporary rotation of the servo motor 1 by providing the first release hole 24 on the brake 2, providing the second release hole 31 on the brake cover 3, providing the release piece 4 in the first release hole 24 and in the second release hole 31, and separating the brake disc 22 and the armature 23 in the brake 2 by the release piece 4, so that the brake disc 22 is in a temporary loose state; the servo motor structure with the manual release function, which is arranged in the mode, can solve the problem that the servo motor 1 can be manually and temporarily released under the condition that the brake 2 cannot normally supply power.

In the above embodiment, it is pointed out that the first release hole 24 penetrates the brake 2 and the armature 23, and on the basis of this, the release member 4 protruding into the first release hole 24 also penetrates the armature 23 of the brake 2, and at the same time, the release member 4 abuts against the inner end surface of the base 21, and by abutting against the inner end surface of the base 21, the armature 23 is provided with a force away from the brake disc 22.

It should be noted that, in this embodiment, the release element 4 is a bolt, and the armature 23 is provided with a threaded hole matching with the bolt, and by rotating the bolt, the armature 23 is pushed away from the brake disc 22 in the opposite direction; specifically, when the bolt is screwed into the first release hole 24 and the bottom abuts against the base 21, the bolt is screwed again, so that the internal thread on the armature 23 is separated from the brake disc 22 under the rotation action of the bolt, and the brake disc 22 is not pressed against the armature 23, thereby realizing the temporary rotation of the servo motor 1.

Of course, other means than the above-mentioned bolt may be used to achieve this purpose, and the detailed description is omitted here, and all of them fall within the scope of protection of the present application.

In addition, it should be noted that the release element 4 is screwed without damaging the internal structure of the brake 2, that is, after the release element 4 separates the brake disc 22 from the armature 23, the servo motor 1 rotates temporarily, and after the release element 4 is taken out from the first release hole 24, the armature 23 presses the armature 23 against the brake disc 22 again under the action of the spring, so that the subsequent normal use of the servo motor 1 is not affected.

Further, in order to ensure the smoothness of the separation process of the armature 23 from the brake disc 22, the number of the first release holes 24 in the embodiment is at least two, and the first release holes are uniformly distributed on the end face of the brake 2; that is, by providing a plurality of first release holes 24 which are uniformly distributed, it is ensured that the brake disc 22 or the armature 23 is uniformly stressed during the separation process, and the situation that one side is separated and the other side is not separated does not occur.

Of course, the number of the second release holes 31 is required to be consistent with that of the first release holes 24, and the second release holes correspond to the first release holes 24 one by one, so that the release members 4 can be conveniently and smoothly inserted by workers, and the operability of the workers is improved.

It should be noted that, in the present embodiment, in order to further ensure the smoothness of the separation process of the armature 23 from the brake disc 22, during the operation, the plurality of release members 4 are required to simultaneously extend into the first release hole 24, and simultaneously push the brake disc 22 and the armature 23 to separate, and ensure that the brake disc 22 and the armature 23 are spaced; that is, during the separation process, it is necessary to keep the separation distance between the armature 23 and the brake disc 22 consistent at each point, and the armature 23 and the brake disc 22 cannot be in contact after separation; strictly speaking, the separation distance of each point does not need to be kept consistent during the separation process of the brake disc 22 and the armature 23, but it is needed to ensure that the armature 23 is not jammed with other parts inside the brake 2 or the separation degree of the one-side release piece 4 is too high.

In this embodiment, the outer end face of the base 21 abuts against the end cover of the servo motor 1, and the brake 2 is fixed on the servo motor 1 through a fixing member, which may be a screw or may be fixed in other manners, but needs to ensure that the arrangement of the release member 4 is not affected, and will not be described in detail herein.

In order to ensure that the brake 2 can be placed in a good working environment, the brake cover 3 is fixed to the end cap of the servomotor 1 and the brake 2 is completely enclosed.

In addition, the rotating shaft 11 of the servo motor 1 extends into the brake 2, and the external gear 12 is disposed on the rotating shaft 11, and the external gear 12 is engaged with the internal gear of the brake disc 22, which is not described herein again, please refer to the arrangement structure of the servo motor 1 and the brake 2 in the prior art.

It should be noted that in this specification, relational terms such as first and second, and the like are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.

The principles and embodiments of the present application are explained herein using specific examples, which are provided only to help understand the method and the core idea of the present application. It should be noted that, for those skilled in the art, it is possible to make several improvements and modifications to the present application without departing from the principle of the present application, and such improvements and modifications also fall within the scope of the claims of the present application.
