Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically a motor structure with dual positioning of the stator and the housing. Background Technology

[0002] Modern motor structures are constantly evolving and improving. On the one hand, with the diversification of application scenarios, motors are gradually developing towards specialization, resulting in various types and structures of motors, such as switched reluctance motors, brushless DC motors, coreless motors, and linear motors. On the other hand, in order to improve motor performance, people have conducted a great deal of research and improvement in motor materials, design, and manufacturing processes, such as adopting new magnetic materials, optimizing motor winding structures and magnetic circuit designs, and improving manufacturing precision.

[0003] Most currently used motor structures cannot achieve dual-positioning of the stator and housing during installation. If this dual-positioning is not possible, only the housing and stator can be fixed in place, but misalignment between the stator and motor during assembly cannot be prevented. This leads to vibration during motor operation, which in turn loosens the motor itself and connected components, affecting the stability of the entire equipment, reducing its lifespan, and potentially causing equipment failure and production interruptions. This results in poor motor usability, a shorter lifespan, and poor heat dissipation. Furthermore, inadequate heat dissipation accelerates the deterioration of the motor's insulation, further shortening its lifespan and increasing the likelihood of short circuits and other malfunctions. Finally, the motor's heat dissipation is also inadequate. Utility Model Content

[0004] The purpose of this invention is to provide a motor structure with dual positioning of the stator and the housing, in order to solve the problems raised in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a motor structure with dual positioning of stator and housing, including a housing, a positioning and mounting mechanism provided at the bottom of the housing, the positioning and mounting mechanism including a fixing plate, the fixing plate being fixedly connected to the bottom of the housing, a fixing block being fixedly connected inside the fixing plate, a slot being provided inside the fixing block, a locking block being fixedly connected to the inner wall of the slot, the inner wall of the locking block being fixedly connected to the outer wall of the housing, an mounting plate being fixedly connected to the outer wall of the fixing plate, a first threaded hole being provided inside the mounting plate, a screw being threadedly connected to the inner wall of the first threaded hole, and a second threaded hole being provided inside the locking block.

[0006] As a preferred technical solution, the fixing block is semi-circular in shape, and there are two fixing blocks.

[0007] As a preferred technical solution, the shape and size of the card slot match the shape and size of the card block, and the shape of the card block is circular.

[0008] As a preferred technical solution, the number of mounting plates is four, and the shape of the mounting plates is semi-circular.

[0009] As a preferred technical solution, the shape and size of the first threaded hole match the shape and size of the screw, and the number of the first threaded holes is four.

[0010] As a preferred technical solution, the second threaded hole is circular in shape, and there are two second threaded holes.

[0011] As a preferred technical solution, a stator assembly is fixedly connected to the inner wall of the housing, a rotor assembly is fixedly connected to the bottom of the stator assembly, and an end cover is movably connected to the bottom of the fixed plate.

[0012] As a preferred technical solution, a fan blade assembly is fixedly connected to the outer wall of the rotor assembly, and the rotor assembly is circular in shape.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of the positioning and installation mechanism, can achieve the function of dual positioning and installation of the stator and the housing. During use, the housing and stator are initially positioned and fixed by the cooperation of the slot and the block. The housing and stator are then positioned and fixed by the cooperation of the screw and the threaded hole. This avoids the situation where only the housing and stator can be fixed by installation due to the inability to achieve dual positioning of the stator and housing. However, this cannot prevent the stator and housing from being misaligned during assembly, causing vibration when the motor is working. This vibration can loosen the motor itself and the equipment components connected to the motor, affecting the stability of the entire equipment, reducing the service life of the equipment, and in severe cases, even causing equipment failure and production interruption. This ensures the practicality and service life of the motor structure.

[0015] 2. This utility model, through the arrangement of the fan blade assembly, can facilitate the dissipation of heat generated during motor operation. During use, the rotation generated by the motor drives the fan blades to rotate, allowing the fan blades to dissipate the heat generated by the motor. This avoids the accumulation of heat inside the motor due to the inconvenience of heat dissipation. Heat accumulation will accelerate the deterioration of the insulation material of the motor, thereby shortening the service life of the motor and increasing the occurrence of faults such as short circuits. This ensures the service life of the motor structure and timely heat dissipation. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figure 1 and Figure 2 As shown, the present invention provides the following technical solution, including a housing 1, a positioning and mounting mechanism 2 at the bottom of the housing 1, a stator assembly 4 fixedly connected to the inner wall of the housing 1, a rotor assembly 5 fixedly connected to the bottom of the stator assembly 4, an end cover 6 movably connected to the bottom of the fixing plate 201, and a fan blade assembly 3 fixedly connected to the outer wall of the rotor assembly 5.

[0024] Specifically: When the motor is needed, it must first be positioned and installed. The positioning and installation mechanism 2 is used to position and install the housing 1 and the stator assembly 4. Then the motor can be used to start working. During the operation of the motor, heat will be generated. At this time, it is necessary to dissipate the heat generated by the motor during operation. The fan blade assembly 3 is used to dissipate the heat generated by the motor during operation, thereby completing the work.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, a positioning and mounting mechanism 2 is provided at the bottom of the housing 1. The positioning and mounting mechanism 2 includes a fixing plate 201, which is fixedly connected to the bottom of the housing 1. A fixing block 202 is fixedly connected inside the fixing plate 201. A slot 203 is formed inside the fixing block 202. A locking block 204 is fixedly connected to the inner wall of the slot 203. The inner wall of the locking block 204 is fixedly connected to the outer wall of the housing 1. An mounting plate 205 is fixedly connected to the outer wall of the fixing plate 201. A first threaded hole 206 is formed inside the mounting plate 205. A screw 2 is threaded into the inner wall of the first threaded hole 206. 07. The internal part of the locking block 204 has a second threaded hole 208. The shape of the fixing block 202 is semi-circular, and there are two fixing blocks 202. The shape and size of the locking groove 203 match the shape and size of the locking block 204, and the shape of the locking block 204 is circular. There are four mounting plates 205, and the shape of the mounting plates 205 is semi-circular. The shape and size of the first threaded hole 206 match the shape and size of the screw 207, and there are four first threaded holes 206. The shape of the second threaded hole 208 is circular, and there are two second threaded holes 208.

[0026] Specifically: When the motor is needed, it must first be positioned and installed. At this time, the fixing plate 201 on the top of the end cover 6 is attached to the fixing plate 201 on the bottom of the housing 1. Then, the bolt is inserted from the bottom into the second threaded hole 208 in the locking block 204 for initial positioning and fixing. Then, the screw 207 is rotated and inserted into the first threaded hole 206 to position and fix the two fixing plates 201, thus fixing the housing 1 and the end cover 6. The positioning and fixing of the locking block 204 of the housing 1 and the locking groove 203 of the fixing plate 201 can prevent the motor from vibrating during operation, thereby completing the positioning and installation work.

[0027] like Figure 1 and Figure 5 As shown, a fan blade assembly 3 is fixedly connected to the outer wall of the rotor assembly 5, and the rotor assembly 5 is circular in shape.

[0028] During the operation of the motor, heat is generated. At this time, it is necessary to dissipate the heat generated by the motor. When the motor is working, the rotor assembly 5 will rotate. When the rotor assembly 5 rotates, it drives the fan blade assembly 3 to start rotating. Through the rotation of the fan blade assembly 3, the air flow inside the motor is promoted, and the heat inside the motor is discharged in time, thereby completing the heat dissipation work.

[0029] The working principle of this utility model is as follows: When the motor is needed, it is first necessary to position and install the motor. At this time, the fixing plate 201 on the top of the end cover 6 is attached to the fixing plate 201 on the bottom of the housing 1. Then, the bolt is inserted from the bottom into the second threaded hole 208 in the locking block 204 for initial positioning and fixing. Then, the screw 207 is rotated and inserted into the first threaded hole 206 to position and fix the two fixing plates 201, thereby fixing the housing 1 and the end cover 6. The positioning and fixing of the locking block 204 of the housing 1 and the locking groove 203 of the fixing plate 201 can prevent the motor from vibrating during operation, thus completing the positioning and installation work. Then, the motor can be used to start working. During the operation of the motor, heat will be generated. At this time, it is necessary to dissipate the heat generated by the motor during operation. When the motor is working, the rotor assembly 5 will rotate. When the rotor assembly 5 rotates, it drives the fan blade assembly 3 to start rotating. Through the rotation of the fan blade assembly 3, the air flow inside the motor is promoted, and the heat inside the motor is discharged in time, thereby completing the heat dissipation work.
