[0003] In some applications, the motor bears a large load or experiences severe load fluctuations. Some of its components may be damaged after prolonged operation and need to be disassembled and replaced. However, some structural designs are quite compact, with narrow space at the motor end, making it difficult for workers to reach in. Even if workers do manage to reach in, there is no room for the wrench to move. Therefore, it is necessary to dismantle other structures in order to remove the motor for replacement, which is very time-consuming and laborious. Utility Model Content

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] Please see Figures 1 to 4 This embodiment provides a motor mounting structure that is easy to assemble and disassemble, including a mounting plate 1, a positioning column 2, a connecting frame 3, and a pressing column 4.

[0022] The mounting plate 1 has multiple first mounting holes 1a, which are used to connect the mounting plate 1 to the machine to be installed. Therefore, the mounting plate 1 and the machine to be installed are generally connected by bolts. One end face of the mounting plate 1 abuts against the machine to be installed, and the other end face abuts against the head end of the motor.

[0023] The positioning post 2 forms a cylindrical abutment part 2a along the first direction. The abutment part 2a is used to connect with the motor mounting hole. Generally, motors have circular mounting holes, which can be connected with the side of the abutment part 2a. Generally, the mounting hole and the abutment part 2a are fitted with a gap, and the gap is as small as possible, so that the abutment part 2a can limit the motor in the radial direction. Multiple positioning posts 2 are connected to the mounting plate 1. Specifically, one end of the positioning post 2 forms a connecting part 2b, which is connected to the abutment part 2a. The mounting plate 1 has multiple first connecting holes 1b, and the multiple positioning posts 2 correspond one-to-one with the multiple first connecting holes 1b. The connecting part 2b is threadedly connected to the first connecting hole 1b. The positioning posts 2 and the mounting plate 1 are detachable. This is to adapt to different models of motors, because the mounting hole sizes of different motors may be different. In this case, the positioning posts 2 with different abutment part 2a sizes can be replaced according to the mounting hole size of the motor to be replaced. In addition, the mounting hole positions of different models of motors may also be different. In this case, the mounting plate 1 needs to have corresponding first connecting holes 1b. Therefore, the positioning posts 2 and the mounting plate 1 can adapt to different models of motors.

[0024] Preferably, the end of the positioning post 2 furthest from the mounting plate 1 along the first direction forms a tapered portion 2c. The diameter of the tapered portion 2c is smaller than that of the abutment portion 2a. Along the direction from the motor to the mounting plate 1, the diameter of the tapered portion 2c gradually increases. During motor installation, the motor mounting hole enters from the tapered portion 2c and gradually transitions to the abutment portion 2a. The gradually increasing diameter of the tapered portion 2c allows installation to be completed without precise positioning. More preferably, the positioning post 2 also forms a tightening portion 2d. The cross-sectional projection of the tightening portion 2d along the first direction is contained within the projection of the abutment portion 2a. The cross-section of the tightening portion 2d is hexagonal. The tightening portion 2d is the position where the operator tightens it with a hex wrench, facilitating the installation and removal of the positioning post 2.

[0025] One end of the connecting frame 3 is connected to the mounting plate 1, and the other end is threaded to the pressure column 4 in the first direction. One end of the pressure column 4 is used to abut against the tail end of the motor. Specifically, the connecting frame 3 includes a first connecting plate 3a and a second connecting plate 3b. One end of the first connecting plate 3a is connected to the mounting plate 1, and the other end is connected to the second connecting plate 3b. The second connecting plate 3b is connected to the pressure column 4.

[0026] Preferably, the easy-to-disassemble motor mounting structure also includes multiple first connecting bolts 5, a first connecting plate 3a is set along a first direction, the first connecting plate 3a has multiple first oblong holes 3aa along a second direction, the second direction is parallel to the end face of the mounting plate 1, the mounting plate 1 has multiple second connecting holes 1c, the multiple first oblong holes 3aa, the multiple second connecting holes 1c and the multiple first connecting bolts 5 correspond one-to-one, and the first connecting bolts 5 pass through the multiple first oblong holes 3aa and are threaded to the second connecting holes 1c. The motor is relatively heavy, so during installation, the motor can be placed on the first connecting plate 3a and then slid towards the mounting plate 1. The side dimensions of different motor models may be different, so the position of the first mounting plate 1 can be adjusted along the second direction to make the motor mounting holes better correspond to the positioning posts 2.

[0027] In a further preferred embodiment, the easy-to-assemble and disassemble motor mounting structure also includes multiple second connecting bolts 6. The first connecting plate 3a has multiple second oblong holes 3ab along the first direction, and the second connecting plate 3b has multiple third connecting holes 3ba. The multiple second oblong holes 3ab and the multiple third connecting holes 3ba correspond one-to-one. The multiple second oblong holes 3ab, the multiple third connecting holes 3ba, and the multiple second connecting bolts 6 correspond one-to-one. The second connecting bolts 6 are threaded to the second oblong holes 3ab and the third connecting holes 3ba. The lengths of different motor models are also different. The position of the second mounting plate 1 can be adjusted along the first direction to make the gap between the second connecting plate 3b and the tail end of the motor appropriate. If the gap is too large, the length of the pressure column 4 may be relatively long.

[0028] Preferably, the easy-to-disassemble motor mounting structure further includes a pressing block 7 and multiple pressing columns 4. One end face of the pressing block 7 abuts against the multiple pressing columns 4, and the other end face is used to abut against the tail end of the motor. The pressing block 7 abuts against the tail end of the motor, so that the motor is subjected to uniform pressure from the pressing columns 4.

[0029] Preferably, the end of the pressure post 4 away from the mounting plate 1 extends outward to form a gripping part 4a, which makes it easy for the operator to grip and rotate the pressure post 4.

[0030] In summary, this application provides a motor mounting structure that facilitates easy assembly and disassembly. During motor installation, the multiple mounting holes of the motor are aligned with the multiple positioning posts 2. The motor is then moved so that the mounting holes align with the positioning posts 2, at which point the motor cannot move radially. Then, the pressing post 4 is rotated so that it presses against the tail end of the motor until the head end of the motor abuts against the mounting plate 1. At this point, the motor cannot move axially either, thus achieving motor installation. The disassembly process is the reverse. During this process, the operator performs the operation at the tail end of the motor, eliminating the need to operate at the narrow head end, greatly improving the convenience of assembling and disassembling the motor.

[0031] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of the claims of this application.
