Abstract
Description
Technical Field
[0001] This application relates to the field of installation equipment technology, and more particularly to an installation device for motor bearings. Background Technology
[0002] An electric motor mainly consists of two parts: a stator and a rotor, used to convert electrical energy into mechanical energy. The rotor is the rotating part of the motor. To reduce the friction generated when the rotor rotates and thus reduce power loss, bearings need to be installed at specific locations on the motor, such as the front and rear end covers.
[0003] Currently, bearing assembly mostly adopts traditional press-fitting methods, which mainly rely on manual operation of ordinary presses or the use of simple tooling for press-fitting.
[0004] However, the pressing force of this pressing method is difficult to control precisely, which can easily lead to large errors in the pressing accuracy of the bearings. This not only affects the subsequent motor assembly process, but also affects the balance and stability of the motor. At the same time, the pressing quality is inconsistent, which affects the overall quality stability of the product. Utility Model Content
[0005] This application provides a motor bearing mounting device to improve the mounting accuracy of motor bearings and enhance the stability of product quality.
[0006] To achieve the above objectives, the main technical solutions adopted in this application include:
[0007] This application provides an installation device for a motor bearing, used to install a motor bearing into a motor component. The installation device includes a drive assembly, a positioning base, and a pressing component. The drive assembly includes a movable end with a degree of freedom of movement along the axial direction of the motor bearing. Along the axial direction of the motor bearing, the positioning base is located on one side of the movable end. The pressing component is located between the positioning base and the movable end. Under the action of the drive assembly, the installation device includes a pressing state and an initial state. When the installation device is in the pressing state, the movable end abuts against the pressing component to install the motor bearing into the motor component. When the installation device is in the initial state, the movable end separates from the pressing component to separate the motor bearing, the motor component, and the pressing component from the positioning base.
[0008] Furthermore, the positioning base includes a first positioning post and a second positioning post arranged coaxially, with the second positioning post connected to the end of the first positioning post facing the press-fitting component; when the mounting device is in the press-fitting state, the first positioning post is connected to the motor component, and the second positioning post is connected to the motor bearing.
[0009] Furthermore, the positioning base also includes a positioning disk, which is connected to the end of the first positioning post away from the press-fitting member, and the positioning disk at least partially abuts against the end face of the motor component.
[0010] Furthermore, the press-fit component has a through hole; when the mounting device is in the press-fit state, the first positioning pin is inserted into the through hole.
[0011] Furthermore, the end of the press-fit component facing the positioning base has an abutment ring, which abuts against the inner or outer ring of the motor bearing.
[0012] Furthermore, the positioning base is detachably mounted on the drive assembly.
[0013] Furthermore, the drive assembly includes a drive frame, on which the mobile end is mounted; and a positioning base that is detachably mounted on the drive frame.
[0014] Furthermore, the drive frame includes a base plate, a guide plate, and a guide column. The guide column is mounted on the base plate, and the guide plate is slidably mounted on the guide column; the movable end is mounted on the guide plate.
[0015] By applying a stable pressing force to the pressing components via a mobile device, the pressing accuracy of motor bearings is improved, thereby enhancing the quality and stability of motor bearing installation. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, as one implementation, this application provides a motor bearing mounting device for stably applying a pressing force to the motor bearing 1, thereby installing the motor bearing 1 into the motor component 2, improving the installation accuracy of the motor bearing 1, and thus improving the stability of product quality.
[0024] Specifically, the installation device includes a drive assembly 3, a positioning base 4, and a pressing component 5. The drive assembly 3 is used to provide pressing force for the installation of the motor bearing 1, the positioning base 4 is used to position the motor bearing 1 and the motor component 2, and the pressing component 5 is used to transmit the pressing force to the motor bearing 1, thereby installing the motor bearing 1 into the motor component 2.
[0025] The drive assembly 3 includes a movable end 301, which has a degree of freedom to move along the axial direction of the motor bearing 1. That is, the movable end 301 can move along the axial direction of the motor bearing 1, and a pressing force is applied to the motor bearing 1 by moving the movable end 301.
[0026] Along the axial direction of the motor bearing 1, the positioning base 4 is located on one side of the moving end 301, and the motor bearing 1 and the motor component 2 are positioned on one side of the moving end 301 by the positioning base 4.
[0027] The press-fitting component 5 is located between the positioning base 4 and the moving end 301, so that the pressing force can be applied to the press-fitting component 5 through the moving end 301, thereby installing the motor bearing 1 to the motor component 2 through the press-fitting component 5.
[0028] Under the action of the drive component 3, the installation device includes a pressing state and an initial state. The pressing state is used to assemble the motor bearing 1 and the motor component 2. The initial state is used to remove the installed motor bearing 1 and the motor component 2, and at the same time, to place the unassembled motor bearing 1 and the motor component 2.
[0029] When the installation device is in the pressing state, the moving end 301 abuts against the pressing part 5, and the moving end 301 applies a pressing force to the pressing part 5, thereby installing the motor bearing 1 into the motor component 2 through the pressing part 5.
[0030] When the installation device is in its initial state, the moving end 301 separates from the press-fit part 5, so as to separate the motor bearing 1, the motor component 2 and the press-fit part 5 from the positioning base 4, thereby enabling the replacement of the motor bearing 1 and the motor component 2.
[0031] The mobile terminal 301 stably applies a pressing force to the pressing component 5, thereby improving the pressing accuracy of the motor bearing 1 and enhancing the quality and stability of the motor bearing 1 installation.
[0032] To more clearly describe the technical solution of this application, the following are defined: Figure 1 The vertical direction is shown. The axial direction of motor bearing 1 is... Figure 1 The up and down directions in the middle.
[0033] like Figure 4 As shown, in one implementation method, when the installation device is in the press-fit state, the axes of the motor bearing 1, the motor component 2, the positioning base 4 and the press-fit component 5 are located in the same straight line.
[0034] It should be noted that in this implementation, the press-fitting component 5, the motor bearing 1, the motor component 2, and the positioning base 4 are arranged from top to bottom. The press-fitting component 5 extends at least partially into the motor component 2, thereby facilitating the installation of the motor bearing 1 into the inner hole of the motor component 2.
[0035] As one implementation method, the press-fit component 5 is set separately from the mobile end 301. When the installation device is in the press-fit state, the press-fit component 5 is partially sleeved on the positioning base 4.
[0036] By fitting the press-fitting component 5 onto the positioning base 4, interference between the press-fitting component 5 and the positioning base 4 during movement can be prevented, reducing the risk of downtime of the installation device and thus improving the continuity of operation of the installation device.
[0037] As another implementation method, the pressing component 5 is fixed on the mobile end 301, and the mobile end 301 drives the pressing component 5 to rise and fall. There is no need for manual installation of the pressing component 5, which improves the automation level of the installation device and thus improves the efficiency of the installation device.
[0038] It should be noted that this application describes the press-fit component 5 and the mobile terminal 301 as being separately configured.
[0039] like Figure 4 As shown, in one implementation, the positioning base 4 includes a first positioning post 401 and a second positioning post 402 arranged coaxially, with the second positioning post 402 connected to the end of the first positioning post 401 facing the press-fitting component 5.
[0040] When the installation device is in the press-fit state, the first positioning post 401 is connected to the motor component 2. The first positioning post 401 cooperates with the shaft hole 201 of the motor component 2 to position the motor component 2. The second positioning post 402 is connected to the motor bearing 1 to position the motor bearing 1, ensuring that the axis of the motor bearing 1 and the axis of the shaft hole 201 are in the same straight line, thereby improving the assembly accuracy of the motor bearing 1 and the motor component 2.
[0041] As one implementation, the positioning base 4 also includes a positioning disk 403, which is connected to the end of the first positioning post 401 away from the press-fitting part 5. The positioning disk 403 at least partially abuts against the bottom end face of the motor component 2. The positioning disk 403 limits the vertical movement of the motor component 2 and provides support for the motor component 2, thereby facilitating the installation of the motor bearing 1 onto the motor component 2.
[0042] The positioning plate 403 is coaxially arranged with the first positioning post 401 and the second positioning post 402 to facilitate the processing of the positioning base 4.
[0043] As one implementation, the positioning base 4 is detachably installed on the drive assembly 3. The positioning base 4 can be replaced according to the size of the motor component 2 and the motor bearing 1, so that the mounting device can press-fit motor components 2 and motor bearing 1 of different sizes, thereby improving the application range of the mounting device.
[0044] As one implementation, a mounting post 404 is formed at the bottom of the positioning base 4, and the positioning base 4 is mounted on the drive assembly 3 through the mounting post 404, thereby improving the ease of disassembly and assembly of the positioning base 4.
[0045] It should be noted that, in order to accommodate motor components 2 and motor bearings 1 of different sizes, this mounting device provides multiple positioning bases 4 of different sizes. The diameters of the first positioning post 401, the second positioning post 402, and the positioning plate 403 of the positioning base 4 can be processed according to the dimensions of the motor components 2 and motor bearings 1. However, the diameters of the mounting posts 404 of different positioning bases 4 are consistent, so as to facilitate the installation of positioning bases 4 of different sizes on the drive assembly 3.
[0046] like Figure 2 and Figure 3 As shown, in one implementation, the drive component 3 includes a drive frame 302, a moving end 301 is mounted on the drive frame 302, the moving end 301 moves under the guidance of the drive frame 302, thereby improving the moving accuracy of the moving end 301, and the positioning base 4 is detachably mounted on the drive frame 302.
[0047] As one implementation, the drive frame 302 includes a base plate 3021, a guide plate 3022, and a guide post 3023. The guide post 3023 is mounted on the base plate 3021, and the axis of the guide post 3023 is parallel to the axis of the motor bearing 1. The guide plate 3022 is mounted on the guide post 3023 through a guide sleeve, so that the guide plate 3022 can slide relative to the guide post 3023. The moving end 301 is mounted on the guide plate 3022.
[0048] It should be noted that the mobile terminal 301 is a cylindrical or prismatic block structure.
[0049] Mounting holes are formed on the base plate 3021, and the positioning base 4 is mounted in the mounting holes of the base plate 3021 via mounting posts 404.
[0050] It should be noted that the mounting post 404 and the mounting holes of the base plate 3021 are connected by an transition fit to ensure the installation accuracy of the positioning base 4 and the base plate 3021, while also ensuring the ease of disassembly and assembly of the positioning base 4 and the base plate 3021.
[0051] As one implementation, the drive frame 302 also includes a return spring 3024, which is sleeved on the guide post 3023, and the two ends of the return spring 3024 are respectively connected to the base plate 3021 and the guide plate 3022.
[0052] The reset spring 3024 provides a reset force to the guide plate 3022. When the installation device is in the initial state, the guide plate 3022 moves upward under the action of the reset spring 3024, thereby separating the moving end 301 installed on the guide plate 3022 from the press-fit part 5, so that the press-fit part 5, the motor bearing 1, and the motor component 2 can be removed from the positioning base 4 in sequence.
[0053] As one implementation, the drive frame 302 also includes a top plate 3025. The top plate 3025 and the bottom plate 3021 are respectively connected to the upper and lower ends of the guide column 3023. The top plate 3025 limits the upper part of the guide plate 3022 to prevent the guide plate 3022 from sliding out from the top of the guide column 3023.
[0054] As one implementation, the driving component 3 also includes a driving element 303, which is positioned toward the mobile end 301 and drives the mobile end 301 to move.
[0055] A through groove 30251 is formed in the middle of the top plate 3025 so that the drive member 303 can pass through the top plate 3025 and connect to the moving end 301.
[0056] It should be noted that the drive component 303 can be one of a hydraulic cylinder, an electric cylinder, or a pneumatic cylinder.
[0057] like Figure 4 As shown, in one implementation, the press-fitting component 5 has a through hole 501. When the mounting device is in the press-fitting state, at least a portion of the second positioning post 402 is inserted into the through hole 501. The second positioning post 402 positions the press-fitting component 5 and the motor bearing 1, ensuring that the press-fitting component 5 can stably apply press-fitting force to the motor bearing 1.
[0058] As one implementation, the end of the press-fit component 5 facing the positioning base 4 has an abutment ring 502, which abuts against the inner or outer ring of the motor bearing 1.
[0059] It should be noted that, under normal circumstances, the abutment ring 502 abuts against the outer ring of the motor bearing 1.
[0060] As one implementation method, the press-fit component 5, the motor bearing 1 and the second positioning post 402 are assembled by means of transition fit, which improves the ease of disassembly and assembly of the press-fit component 5, the motor bearing 1 and the second positioning post 402, while ensuring the assembly accuracy of the press-fit component 5 and the motor bearing 1.
[0061] Similarly, the shaft hole 201 of the motor component 2 and the first positioning post 401 are also assembled by transition fit, which improves the ease of disassembly and assembly of the motor component 2 and the first positioning post 401, and at the same time improves the assembly accuracy of the motor bearing 1 and the bearing hole 202 of the motor component 2.
[0062] like Figure 1 As shown, as one implementation method, the installation device also includes a frame 6 and a control panel 7. The control panel 7 and the drive component 3 are respectively installed on the frame 6. The control panel 7 controls the operation of the drive component 3, so that the installation device switches between the pressing state and the initial state.
[0063] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
[0064] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by the appended claims.
