Description

Technical Field

[0001] This utility model belongs to the field of heat dissipation technology for housings, and particularly relates to a cooling device for motor housings. Background Technology

[0002] With advancements in motor manufacturing processes, motor housings are typically produced using die-casting of aluminum alloys or welding of steel. After molding, the housing temperature can reach over 200°C, requiring rapid cooling to room temperature for subsequent machining or assembly. Due to the high coefficient of thermal expansion of aluminum alloys, uneven cooling can easily lead to deformation, affecting the assembly accuracy of the motor stator. Furthermore, mass production lines for motor housings require minimal cooling time (less than 5 minutes) to avoid impacting production efficiency.

[0003] However, existing housing cooling devices typically employ a series structure of a single condenser and a single fan. This single-condenser-single-fan series structure is insufficient to rapidly cool the motor housing to room temperature. Furthermore, the cooling airflow of this structure cannot reach all parts of the housing, resulting in uneven cooling and heat dissipation in certain areas, which fails to meet the precision requirements of current motor housing cooling processes. Utility Model Content

[0028] In one embodiment of this utility model, such as Figures 1-4 As shown, a motor housing cooling device is provided, comprising a support mechanism 1, a housing limiting mechanism 2, a cooling mechanism 3, a first cylinder 4, and a linear module 5, wherein:

[0029] The support mechanism 1 consists of two layers: the lower layer comprises two rectangular support bases, and the upper layer is a support plate 104. The two layers are connected by support columns. The lower support base has pin holes for easy replacement of the overall cooling device. The support plate 104 includes a first long side and a second long side, which are parallel to each other. A linear module 5 is fixed to the first long side of the support plate 104, and a guide rail 101 is provided on the second long side. One end of the housing limiting mechanism 2 is fixedly connected to the slide table on the linear module 5; the other end of the housing limiting mechanism 2 is slidably connected to the guide rail 101. A power cylinder on the linear module 5 is fixedly connected to the slide table. When the power cylinder is activated, it drives the slide table, the housing limiting mechanism 2, and the housing to move along the guide rail. Positioning sensors 103 are also provided on both sides of the guide rail 101. The positioning sensors 103 can detect the displacement of the housing limiting mechanism 2 on the guide rail, ensuring that the housing limiting mechanism 2 moves the housing to the cooling position directly below the condenser.

[0030] The housing limiting mechanism 2 includes a base plate 204, a first positioning pin 201, a second positioning pin 203, a limiting block 202, and a first photoelectric sensing device 7. The base plate 204 is fixed on both sides of the linear module 5 and the guide rail 101, respectively. The limiting block 202 is positioned in the middle of the base plate 204. The upper end of the limiting block 202 has a rectangular protrusion, and the side ends of the limiting block 202 are recessed inwards. The protrusion and recess are adapted to the shape of the housing end cap, allowing the housing end cap to engage with the limiting block 202 for further engagement with the positioning pins. The housing is positioned using a limiting mechanism. A first positioning pin 201 is located at the top center of the limiting block 202. The top of the first positioning pin 201 has a circular boss design and is used to insert into the positioning hole in the middle of the housing end cap to position the center of the housing. A second positioning pin 203 is located at the edge of the limiting block 202. The top of the second positioning pin 203 also has a circular boss design and is used to insert into the positioning hole on the edge of the housing end cap to position the edge of the housing. Under the action of the two positioning pins, the position of the housing is accurately positioned. A first photoelectric sensor 7 is located at the edge of the base plate 204 to detect whether the housing has been accurately positioned. In a specific embodiment of this utility model, the first photoelectric sensor 7 can emit a sensing laser. The area covered by the sensing laser is the laser sensing area. By adjusting the relative position of the emitting end of the first photoelectric sensor 7 and the connecting rod, the emission angle of the sensing laser can be adjusted. The emission angle of the laser sensing is at a 60-degree angle with the horizontal direction. When the housing is placed on the housing limiting mechanism 2 and the laser sensing area detects the position of the housing, it indicates that the housing has been accurately positioned.

[0031] The cooling mechanism 3 includes a first cooling component 301 and a second cooling component 302. The first cooling component 301 includes a condenser 3011 and a first fan 3012. A first cylinder 4 is located on the first short side of the support plate 104. The condenser 3011 is connected to the first cylinder 4 and is used to drive the first cooling component 301 to move up and down. The condenser 3011 has a coolant flow channel inside, and the coolant flowing through the condenser 3011 can continuously release cold air. The condenser 3011 has a circular notch, and the first fan 3012 covers the circular notch with the air outlet facing downwards, blowing the cold air released by the condenser 3011 into the housing. The first cooling assembly 301 is equipped with a second photoelectric sensor 8. The sensing laser of the second photoelectric sensor 8 is emitted vertically downward. When the second photoelectric sensor 8 senses that the housing limiting mechanism 2 has moved into the laser sensing area of ​​the second photoelectric sensor 8, the first cylinder 4 is activated to drive the first cooling assembly 301 to move downward until the condenser 3011 covers the opening of the housing. The condenser 3011 and the first fan 3012 are activated to start cooling and heat dissipation of the housing.

[0032] The second cooling assembly 302 includes a vertical plate 3021 and a second fan 3022. The vertical plate 3021 has a circular hole, and the second fan 3022 covers the circular hole with its air outlet facing left, further dissipating heat from the side of the housing. The second cooling assembly 302 is equipped with a third photoelectric sensor 9. The sensing laser of the third photoelectric sensor 9 is emitted in a horizontal direction. When the third photoelectric sensor 9 senses that the housing limiting mechanism 2 has moved into the laser sensing area of ​​the third photoelectric sensor 9, the second fan 3022 is activated, and begins to cool the housing from the side.

[0033] In a preferred embodiment, the laser sensing areas of the second photoelectric sensing device 8 and the third photoelectric sensing device 9 overlap. When the housing is moved to the cooling position, the second photoelectric sensing device 8 and the third photoelectric sensing device 9 simultaneously sense the housing and activate the first fan 3012 and the second fan 3022 respectively for cooling and heat dissipation. Therefore, the first cooling component 301 and the second cooling component 302 cool and dissipate heat on the housing simultaneously, which can simultaneously cool and dissipate heat on the inner and outer walls of the housing, and at the same time dissipate heat on the end cap and the main body of the housing, avoiding uneven local heat dissipation.

[0034] In a preferred embodiment, since the housing has a certain volume, when the front end of the housing enters the laser sensing area of ​​the second photoelectric sensor 8 and the third photoelectric sensor 9, it can be sensed by the second photoelectric sensor 8 and the third photoelectric sensor 9. However, at this time, the housing as a whole has not completely moved to the cooling position. Therefore, the detection sensing signal received by the second photoelectric sensor 8 and the third photoelectric sensor 9 cannot be used as the basis for stopping the housing displacement. Only when the positioning sensing devices 103 at both ends of the guide rail 101 detect that the housing has accurately moved to the cooling position can a control signal be sent to drive the linear module 5 to brake the housing limiting mechanism 2 and the housing, so as to achieve accurate control of the housing displacement.

[0035] In a preferred embodiment, an air-blocking groove 102 is provided at the position of the support plate 101 corresponding to the lower part of the condenser. The air-blocking groove 102 is used to form a downward airflow passage to prevent the cooling gas flowing through the shell from stagnating inside the shell and affecting the heat dissipation efficiency.

[0036] As a preferred embodiment, a cable drag chain 6 is also provided on one side of the housing cooling device to protect the cable connecting the first cylinder 4 and the linear module 5 from wear when the equipment is moved.

[0037] This application provides a motor housing cooling device, the operation process of which is as follows:

[0038] 1. Place the overheated housing onto the housing limiting mechanism, use the positioning pin and limiting block to accurately position the housing, and use a photoelectric sensor to sense whether the housing has completed the accurate positioning.

[0039] 2. Once the housing is precisely positioned, the linear module is activated to move the housing along the guide rail. The positioning sensors on both sides of the guide rail accurately detect the displacement distance of the housing. Once the housing reaches the cooling position, the system controls the housing to stop moving.

[0040] 3. After the photoelectric sensor of the first cooling component detects that the housing has reached the bottom of the condenser, the first cylinder drives the first cooling component to move downward until the condenser covers the opening of the housing. The first cooling component is then activated to cool and dissipate heat from the housing.

[0041] 4. While step 3 is being performed, the photoelectric sensor of the second cooling component detects that the housing has reached the horizontal sensing area, and the second fan starts to cool and dissipate heat from the housing.

[0042] 5. Once cooling and heat dissipation are complete, the first and second cooling components are shut down, and the first cylinder drives the first cooling component to rise, removing the cooling housing.

[0043] This application provides a motor housing cooling device. The housing is fixed to a housing limiting mechanism via a locating pin, a limiting block adapted to the housing shape, and a photoelectric sensor. A linear module and a guide rail drive the housing to move along the guide rail. A first cylinder connects to a first cooling component, causing a condenser to cover the housing. A second cooling component, perpendicular to each other and parallel to the first cooling component, is provided on the side of the first cooling component, achieving efficient dual-line parallel heat dissipation and rapidly reducing the housing temperature. By providing a positioning sensor in the support mechanism and photoelectric sensors on the first and second cooling components, the displacement of the housing on the guide rail can be detected efficiently and accurately, pushing the housing to the cooling position and automating the aforementioned pushing and cooling operation process.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
