Description

Technical Field

[0001] The invention belongs to the technical field of encoder installation, and in particular relates to an auxiliary installation component and a split encoder installation method. Background Art

[0002] For split-type inductive rotary encoders, in practical applications, the air gap between the stator and rotor is a key factor, which will directly affect the detection accuracy and detection function of the encoder product; therefore, during the terminal installation of the encoder, the air gap between the stator and rotor is required to be controlled within a certain range (the air gap range is different for encoders of different sizes and structures).

[0003] The existing method is to customize the sleeve according to the different shaft lengths of the terminal shaft (the customized sleeve generally has a limited step, etc.) so that the matching height of the sleeve and the terminal shaft meets the required range of the air gap between the stator and the rotor. The advantage of this method is that it is easy to install and there is no need to adjust the air gap. The disadvantage is that there are many types of customized sleeves, which are not easy to manage, and large-scale fixed production is impossible, and the cost of customized sleeves is high.

[0004] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0005] The object of the present invention is to provide an auxiliary installation component and a split encoder installation method, which can be used in conjunction with a universal shaft sleeve to install the split encoder and meet the air gap requirements.

[0006] In order to achieve the above-mentioned purpose, a specific embodiment of the present invention provides an auxiliary installation component for installation between a split encoder and a motor, wherein the split encoder is installed on a base, and the output shaft of the motor passes through the base and is fixedly installed with a first PCB board of the split encoder through a universal sleeve, and the auxiliary installation component includes: a connecting member and a limiting member installed at one end of the connecting member and extending outward, wherein the limiting member is located between the first PCB board and the base, and the limiting member limits the first PCB board based on its own height to limit the distance between the lower surface of the first PCB board and the upper surface of the base.

[0007] In one or more embodiments of the present invention, the limiting member includes a base and an abutting portion located on the base, and the abutting portion is in line contact with the lower surface of the first PCB board.

[0008] In one or more embodiments of the present invention, a maximum contact width between the abutting portion and the lower surface of the first PCB board is 0.1-0.3 mm.

[0009] In one or more embodiments of the present invention, the limiting member has two opposite side walls, the two side walls are connected to the connecting member and at least one side wall is in an arc shape.

[0010] In one or more embodiments of the present invention, the wall surface of the arc-shaped side wall and the inner wall surface of the retaining ring on the base have the same curvature radius.

[0011] In one or more embodiments of the present invention, an avoidance groove is formed at the bottom of one end of the limiting member away from the connecting member.

[0012] In one or more embodiments of the present invention, the auxiliary installation assembly further includes a hand piece, and the hand piece and the limiting piece are respectively installed at two ends of the connecting piece.

[0013] In one or more embodiments of the present invention, one end of the handpiece is connected to the connecting member, and the other end extends in a direction away from the limiting member.

[0014] The present invention also discloses a split encoder installation method, comprising:

[0015] Install the base on the motor, and the output shaft of the motor passes through the base;

[0016] Placing the auxiliary installation assembly on the upper surface of the base so that the bottom of the stopper fits the upper surface of the base;

[0017] The universal sleeve is sleeved on the output shaft of the motor, the first PCB is sleeved on the universal sleeve, and the lower surface of the first PCB is fitted with the upper surface of the stopper to fix the universal sleeve and the first PCB;

[0018] Rotate the auxiliary installation component and take it out through the space around the first PCB board;

[0019] Install the second PCB board onto the positioning posts of the base.

[0020] In one or more embodiments of the present invention, two or more auxiliary mounting components are placed on the upper surface of the base.

[0021] Compared with the prior art, the auxiliary installation component and the split encoder installation method of the present invention can cooperate with the universal sleeve to install the split encoder on the rotating shaft of the motor. The auxiliary installation component can limit the position of the first PCB board when the motor shaft has different shaft lengths, thereby solving the problem that the position of the first PCB board on the universal sleeve is difficult to grasp. After the split encoder is installed on the rotating shaft of the motor, the air gap requirement range between the first PCB board and the second PCB board can be met, so there is no need to customize the sleeve, reducing the cost of using customized sleeves and facilitating management.

[0033] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0034] like Figure 1 As shown, an auxiliary mounting assembly 10 in one embodiment of the present invention is used for the installation between a split encoder and a motor 20, the split encoder is mounted on a base 30, the motor 20 is mounted on the bottom of the base 30, and the output shaft 201 of the motor 20 passes through the base 30 and is fixedly mounted with the first PCB board 401 of the split encoder through a universal sleeve 50.

[0035] like Figure 2 , 3 As shown in Figures 4 and 5, the auxiliary installation assembly 10 includes: a connecting member 1 and a limiting member 2 installed at one end of the connecting member 1 and extending outward, and the auxiliary installation assembly 10 also includes a hand piece 3, the hand piece 3 and the limiting member 2 are respectively installed at both ends of the connecting member 1, one end of the hand piece 3 is connected to the connecting member 1, and the other end extends in a direction away from the limiting member 2, one end of the limiting member 2 is connected to the connecting member 1, and the other end extends in a direction away from the limiting member 2, and the hand piece 3 and the limiting member 2 extend toward both sides of the connecting member 1 respectively. In one embodiment, the limiting member 2 is located at the bottom of the connecting member 1, the hand piece 3 is located at the top of the connecting member 1, and the connecting member 1, the limiting member 2 and the hand piece 3 are integrally formed.

[0036] When the split encoder is installed, the limiter 2 is located between the first PCB board 401 and the base 30 . The limiter 2 limits the first PCB board 401 based on its own height to limit the distance between the lower surface of the first PCB board 401 and the upper surface of the base 30 .

[0037] Specifically, the stopper 2 includes a base 21 and an abutment portion 22 located on the base 21. The base 21 is in an elongated strip shape, and the bottom of the base 21 is a plane. The abutment portion 22 is in line contact with the lower surface of the first PCB board 401. In one embodiment, the maximum contact width between the abutment portion 22 and the lower surface of the first PCB board 401 is 0.1 to 0.3 mm. By reducing the contact width, the wear on the first PCB board 401 when the auxiliary mounting assembly 10 moves is reduced.

[0038] The stopper 2 has two opposite side walls, the two side walls are connected to the connecting member 1 and at least one side wall is in an arc shape, and the wall surface of the arc-shaped side wall has the same curvature radius as the inner wall surface of the retaining ring 301 on the base 30. In one embodiment, the two side walls of the stopper 2 are in an arc shape parallel to each other, and the abutting portion 22 is also in an arc shape parallel to the side walls.

[0039] In one embodiment, an avoidance groove 22 is provided at the bottom of the end of the limiting member 2 away from the connecting member 1, and the avoidance groove 22 is used to avoid the protrusion on the base 30. In other embodiments, the avoidance groove 22 can also be set at other positions on the bottom of the connecting member 1 as needed to avoid the protrusion on the base 30.

[0040] This embodiment also discloses a split encoder installation method, including:

[0041] First, Figure 5 As shown, the base 30 is mounted on the mounting surface of the motor 20 , and the output shaft 201 of the motor 20 passes through the base 30 . It can be seen that the end of the output shaft 201 of the motor 20 is in a step shape.

[0042] Then as Figure 6 As shown, the auxiliary installation assembly 10 is placed on the upper surface of the base 30 so that the bottom of the stopper 2 is in contact with the upper surface of the base 30. Two or more auxiliary installation assemblies 10 are placed on the upper surface of the base 30. In one embodiment, two auxiliary installation assemblies 10 are placed on the upper surface of the base 30 opposite to each other.

[0043] like Figure 1 As shown, the universal sleeve 50 is sleeved on the output shaft 201 of the motor 20, the first PCB board 401 is sleeved on the universal sleeve 50, and the first PCB board 401 is pressed so that the lower surface of the first PCB board 401 is in contact with the top of the abutment portion 22 of the stopper 2, and the universal sleeve 50 and the first PCB board 401 are fixed. In one embodiment, as Figure 7 As shown, the universal sleeve 50 is fixed to the output shaft 201 of the motor 20 by means of a fixing member 60 such as a screw. The locking fixing member 60 needs to press the first PCB board 401 so that the lower surface of the first PCB board 401 and the limit member 2 always keep in contact.

[0044] like Figure 8 As shown, the auxiliary installation assembly 10 is rotated and taken out through the space between the first PCB board 401 and the retaining ring 301 on the base 30. At this time, the limiter 2 provided on the arc-shaped side wall can not interfere with the edge of the retaining ring 301 during rotation, so as to meet the installation and use of various bases 30 and various motors and split encoders.

[0045] like Fig. 9As shown, the second PCB board 402 is mounted on the positioning column 302 of the base 30. In one embodiment, the second PCB board 402 is fixed to the positioning column 302 by screws or the like.

[0046] like Fig.10 As shown, the air gap between the first PCB board 401 and the second PCB board 402 is detected and confirmed using a measuring tool 60 to confirm whether the air gap meets the product use requirements. In one embodiment, the measuring tool 60 can be a feeler gauge.

[0047] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
