The first shell is connected to the second shell, and the transmission structure is arranged in the first shell. The second shell is provided with a mounting hole for installing the rotating shaft. The rotating shaft passes through the mounting hole and has a clearance fit with the mounting hole. One end of the rotating shaft located between the first shell and the second shell is connected to the transmission structure, so that the transmission structure can drive the rotating shaft to rotate.

[0003] When assembling the motor, firstly, the rotating shaft is passed through the mounting hole, and then the first housing on which the transmission structure is mounted is connected to the second housing, so that the rotating shaft is matched with the transmission structure.

[0004] However, the shaft and the mounting hole are clearance-matched, so that when the first shell and the second shell are connected, the matching accuracy of the shaft and the transmission structure is poor, resulting in poor smoothness of the shaft rotation after the first shell and the second shell are connected. Utility Model Content

[0005] In order to improve the assembly accuracy of the rotating shaft and the transmission structure, the present application provides an auxiliary device for motor installation.

[0006] The present application provides an auxiliary device for motor installation, which adopts the following technical solution:

[0007] An auxiliary device for motor installation, comprising:

[0008] A first positioning portion, wherein the first positioning portion is formed with a first positioning hole and a second positioning hole, and the first positioning hole is coaxial with and connected to the second positioning hole;

[0009] The second positioning portion is used to position the rotating shaft along the axial direction of the second positioning hole.

[0010] By adopting the above technical solution, the second housing is inserted into the first positioning hole so that the first positioning hole is coaxial with the mounting hole. At this time, the second positioning hole is coaxial with the mounting hole. Then the rotating shaft passes through the second positioning hole and the mounting hole. The coaxiality of the rotating shaft relative to the mounting hole is improved through the matching relationship between the rotating shaft and the second positioning hole, thereby improving the verticality of the rotating shaft relative to the second housing, so as to improve the matching accuracy of the rotating shaft and the transmission structure, and improve the smoothness of the rotating shaft rotation after the motor is assembled. The second positioning portion is used to position the rotating shaft along the axial direction of the second positioning hole.

[0011] Optionally, the first positioning portion is threadedly connected with a first locking portion along a direction perpendicular to the axis of the second positioning hole, and the first locking portion is used to press against the rotating shaft to lock the rotating shaft.

[0012] By adopting the above technical solution, when the rotating shaft is inserted into the first positioning hole and moved to the assembly position, the first locking portion is threadedly connected to the first positioning portion, so that the first locking portion is pressed against the rotating shaft to lock the rotating shaft, thereby eliminating the need for assemblers to fix the position of the rotating shaft by hand, thereby facilitating assembling the motor for assemblers.

[0013] Optionally, a first positioning surface is formed at one end of the first positioning portion.

[0014] By adopting the above technical solution, when the second shell is inserted into the first positioning hole, the first positioning surface abuts against the end surface of the second shell, thereby improving the position accuracy of the shaft along the axis direction of the mounting hole and improving the verticality of the first positioning hole and the mounting hole.

[0015] Optionally, the second positioning portion is threadedly connected to the rotating shaft, and a second positioning surface is formed at one end of the second positioning portion.

[0016] By adopting the above technical solution, after the second positioning part is threadedly connected to the rotating shaft, the second positioning surface abuts against the end surface of the first positioning part, thereby improving the position accuracy of the rotating shaft along the axis direction of the mounting hole. The threaded assembly method is convenient for processing and assembly.

[0017] Optionally, the first positioning portion is provided with a positioning groove, and the second positioning portion is provided with a first clamping block for cooperating with the positioning groove.

[0018] By adopting the above technical solution, when the second positioning surface abuts against the first positioning portion, the first clamping block cooperates with the positioning groove, thereby limiting the rotation of the rotating shaft and facilitating the positioning of the rotating shaft.

[0019] Optionally, the first positioning portion is provided with a first sliding groove along the radial direction of the second positioning hole, the first sliding groove is communicated with the second positioning hole, and the inner wall of the first sliding groove is slidably connected with a second locking portion and a third locking portion;

[0020] It includes a driving assembly, which is used to drive the second locking part and the third locking part to move simultaneously. The second locking part and the third locking part are used to lock the rotating shaft so that the rotating shaft is coaxial with the second positioning hole when locked.

[0021] By adopting the above technical solution, the second locking part and the third locking part can clamp the rotating shafts of different diameters. The second locking part and the third locking part move simultaneously, so that the second locking part and the third locking part can clamp the rotating shaft while making the rotating shaft coaxial with the second positioning hole.

[0022] Optionally, the second locking portion and the third locking portion are both V-shaped blocks.

[0023] By adopting the above technical solution, the two V-shaped blocks can clamp the rotating shaft and position the rotating shaft at the same time, so that the rotating shaft is coaxial with the second positioning hole, and the V-shaped blocks can clamp and position rotating shafts of different diameters, and the structure is simple and compact.

[0024] Optionally, the driving assembly includes a first connecting rod and a second connecting rod that are crossed and rotatably connected at a middle position, an elastic member is connected between the first connecting rod and the second connecting rod, one end of the first connecting rod is slidably connected to the second locking portion, and one end of the second connecting rod is slidably connected to the third locking portion.

[0025] By adopting the above technical solution, when the rotating shaft does not penetrate into the second positioning hole, the elastic member makes the gap between the second locking part and the third locking part smaller. When the rotating shaft needs to be clamped, the assembler rotates the first connecting rod and the second connecting rod to compress and deform the elastic member, and the first connecting rod and the second connecting rod drive the second locking part and the third locking part to move away from each other to increase the gap between the second locking part and the third locking part, and then inserts the rotating shaft into the gap between the second locking part and the third locking part, and then the assembler loosens the first connecting rod and the second connecting rod, and the elastic member recovers the deformation, so that the first connecting rod and the second connecting rod rotate, so that the second locking part and the third locking part move toward each other to clamp the rotating shaft.

[0026] In summary, the present application includes at least one of the following beneficial effects:

[0027] 1. The second housing is inserted into the first positioning hole so that the first positioning hole is coaxial with the mounting hole. At this time, the second positioning hole is coaxial with the mounting hole. Then the rotating shaft passes through the second positioning hole and the mounting hole. The coaxiality of the rotating shaft relative to the mounting hole is improved through the matching relationship between the rotating shaft and the second positioning hole, thereby improving the verticality of the rotating shaft relative to the second housing, so as to improve the matching accuracy of the rotating shaft and the transmission structure, and improve the smoothness of the rotating shaft rotation after the motor is assembled. The second positioning portion is used to position the rotating shaft along the axial direction of the second positioning hole;

[0028] 2. When the rotating shaft is inserted into the first positioning hole and moved to the assembly position, the first locking portion is threadedly connected with the first positioning portion so that the first locking portion is pressed against the rotating shaft to lock the rotating shaft, thereby eliminating the need for assemblers to fix the position of the rotating shaft by hand, which facilitates the assembly of the motor;

[0029] 3. The second locking part and the third locking part can clamp the rotating shafts of different diameters. The second locking part and the third locking part move simultaneously, so that the second locking part and the third locking part clamp the rotating shaft and make the rotating shaft coaxial with the second positioning hole at the same time;

The two V-shaped blocks can clamp the rotating shaft and position the rotating shaft at the same time, so that the rotating shaft is coaxial with the second positioning hole, and the V-shaped blocks can clamp and position rotating shafts of different diameters, and the structure is simple and compact.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] Reference Figure 1 The motor includes a rotating shaft 18, a first housing 16 and a second housing 17 that cooperate with each other. A threaded section is provided at one end of the rotating shaft 18. A transmission structure is installed on the first housing 16. The transmission structure cooperates with the end of the rotating shaft 18 away from the threaded section. The second housing 17 includes a cylindrical structure. The cylindrical structure is provided with a mounting hole that penetrates the second housing 17. The rotating shaft 18 is loosely matched with the mounting hole. When assembling the motor, the rotating shaft 18 is inserted into the mounting hole, and then the first housing 16 and the second housing 17 are matched, and the rotating shaft 18 is matched with the transmission structure. When the rotating shaft 18 is matched with the transmission structure, the verticality of the rotating shaft 18 and the first housing 16 needs to meet the assembly requirements.

[0039] Embodiment 1:

[0040] The present application discloses an auxiliary device for motor installation, referring to Figure 2The auxiliary device for motor installation includes a first positioning portion 1 and a second positioning portion 10. The first positioning portion 1 and the second shell 17 are detachably connected through the cooperation of a flange and bolts. The second positioning portion 10 is located on the side of the first positioning portion 1 away from the second shell 17. The second positioning portion 10 is threadedly connected to the threaded section of the rotating shaft 18.

[0041] Reference Figure 3 The first positioning portion 1 is cylindrical, and an end surface close to the second shell 17 is named as the first positioning surface 4. The first positioning portion 1 is provided with a first positioning hole 2 and a second positioning hole 3 along its axial direction. The first positioning hole 2 is coaxial with the first positioning portion 1 and is opened at an end surface of the first positioning portion 1 close to the second shell 17. The first positioning hole 2 is a blind hole. The second positioning hole 3 is coaxial with the first positioning portion 1 and is opened at an end surface of the first positioning portion 1 away from the second shell 17. The second positioning hole 3 is connected to the first positioning hole 2. The side wall of the first positioning portion 1 is threadedly connected with two first locking portions 5 along its radial direction. The first locking portions 5 are bolts. The two first locking portions 5 are spaced apart along the axial direction of the first positioning portion 1, and both penetrate the side wall of the first positioning portion 1, so that one end of the first locking portion 5 can be inserted into the second positioning hole 3.

[0042] When assembling the motor, firstly, the first positioning part 1 is sleeved on the outer side of the cylindrical structure of the second housing 17, so that the cylindrical structure of the second housing 17 is inserted into the first positioning hole 2, and the cylindrical structure of the second housing 17 is coaxial with the first positioning hole 2, then the first positioning part 1 is moved, so that the first positioning surface 4 is in contact with the second housing 17, and the first positioning part 1 and the second housing 17 are connected by the flange and the bolt. Then, the end of the rotating shaft 18 away from the threaded section is passed through the second positioning hole 3, the first positioning hole 2 and the mounting hole in sequence, so that the rotating shaft 18 is coaxial with the cylindrical structure of the second housing 17, and then the first locking part 5 is threadedly connected with the first positioning part 1, so that the first locking part 5 is pressed against the rotating shaft 18 to lock the position of the rotating shaft 18 and reduce the situation of the rotating shaft 18 rotating or moving during assembly. Then, the first housing 16 is matched with the second housing 17, and the rotating shaft 18 is matched with the transmission structure.

[0043] The matching relationship between the first positioning surface 4 and the second housing 17 improves the verticality between the axis of the first positioning part 1 and the second housing 17, and the matching relationship between the first positioning hole 2 and the cylindrical structure improves the coaxiality between the axis of the first positioning part 1 and the mounting hole. The second positioning hole 3 of the first positioning part 1 can improve the coaxiality between the rotating shaft 18 and the axis of the first positioning part 1, and reduce the shaking of the rotating shaft 18 relative to the mounting hole, so that the operator can assemble the rotating shaft 18 with the transmission structure.

[0044] Reference Figure 3The threaded section of the rotating shaft 18 is threadedly connected with the second positioning portion 10. The second positioning portion 10 is cylindrical. When the rotating shaft 18 is threadedly connected with the second positioning portion 10, the rotating shaft 18 is coaxial with the second positioning portion 10. The end face of the second positioning portion 10 close to the first positioning portion 1 is named as the second positioning surface 11. Before assembling the motor, the threaded section of the rotating shaft 18 is threadedly connected with the second positioning portion 10. During the assembly of the motor, the rotating shaft 18 passes through the second positioning hole 3, the first positioning hole 2 and the mounting hole in sequence, so that the second positioning surface 11 abuts against the first positioning portion 1, thereby positioning the rotating shaft 18 along the axis direction of the mounting hole. At the same time, the abutment of the second positioning surface 11 with the first positioning portion 1 can further improve the verticality of the rotating shaft 18 relative to the first positioning portion 1, thereby improving the coaxiality of the axis of the rotating shaft 18 and the first positioning portion 1.

[0045] Reference Figure 2 The first positioning portion 1 has a positioning groove 9 at one end away from the first positioning surface 4 along the axial direction of the first positioning portion 1, and the second positioning portion 10 has a first clamping block 12 fixedly connected at one end close to the second positioning surface 11. When the second positioning surface 11 abuts against the first positioning portion 1, the first clamping block 12 is plugged into the positioning groove 9, thereby positioning the rotating shaft 18 along the circumferential direction of the first positioning portion 1, making it easier for the assembler to assemble the rotating shaft 18.

[0046] The implementation principle of the auxiliary device for motor installation in the embodiment of the present application is as follows: the cylindrical structure of the second housing 17 is inserted into the first positioning hole 2, so that the first positioning hole 2 is coaxial with the mounting hole, and the second positioning hole 3 is coaxial with the mounting hole at this time, and then the rotating shaft 18 passes through the second positioning hole 3, the first positioning hole 2 and the mounting hole in sequence, and the coaxiality of the rotating shaft 18 relative to the mounting hole is improved through the matching relationship between the rotating shaft 18 and the second positioning hole 3, thereby improving the verticality of the rotating shaft 18 relative to the second housing 17, so as to improve the matching accuracy of the rotating shaft 18 and the transmission structure, and improve the smoothness of the rotation of the rotating shaft 18 after the motor is assembled. The second positioning portion 10 is used to position the rotating shaft 18 along the axial direction of the second positioning hole 3.

[0047] Embodiment 2:

[0048] The difference between the present embodiment and other embodiments is that Figure 4 and Figure 5 A first sliding groove 6 is provided in the radial direction on one end face of the first positioning portion 1 away from the first positioning surface 4. The first sliding groove 6 passes through the first positioning portion 1. A second locking portion 7 and a third locking portion 8 are slidably connected in the first sliding groove 6. Both the second locking portion 7 and the third locking portion 8 are V-shaped blocks, and the openings of the two V-shaped blocks are opposite to each other.

[0049] Reference Figure 5The first positioning part 1 is rotatably connected to the first connecting rod 13 and the second connecting rod 14 at one end away from the first positioning surface 4. The first connecting rod 13 and the second connecting rod 14 are cross-connected and coaxially rotatably connected. The rotation axis of the first connecting rod 13 and the second connecting rod 14 is parallel to the axis direction of the first positioning part 1. An elastic member 15 is connected between the first connecting rod 13 and the second connecting rod 14. The elastic member 15 is a spring. One end of the first connecting rod 13 is slidably connected to the second locking part 7, and one end of the second connecting rod 14 is slidably connected to the third locking part 8.

[0050] When the first link 13 and the second link 14 rotate, the second locking portion 7 and the third locking portion 8 can be moved toward a direction approaching each other or away from each other.

[0051] Before inserting the rotating shaft 18 into the second positioning hole 3, the assembler rotates the first connecting rod 13 and the second connecting rod 14, so that the elastic member 15 is compressed and deformed, and the second locking portion 7 and the third locking portion 8 move in a direction away from each other, so that the rotating shaft 18 can be inserted into the second positioning hole 3. When the rotating shaft 18 moves to the assembly position, the assembler releases the control of the first connecting rod 13 and the second connecting rod 14, the elastic member 15 recovers its deformation, and the second locking portion 7 and the third locking portion 8 move in a direction close to each other, so that the second locking portion 7 and the third locking portion 8 clamp the rotating shaft 18 together and make the rotating shaft 18 coaxial with the second positioning hole 3. The V-shaped block enables the second locking portion 7 and the third locking portion 8 to clamp the rotating shaft 18 of different diameters and make the rotating shaft 18 coaxial with the second positioning hole 3, thereby improving the versatility of the auxiliary device for motor installation.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
