Description

Technical Field

[0001] This utility model relates to the field of brushless motor manufacturing technology, and in particular to a brushless motor housing spraying device. Background Technology

[0002] Brushless motors, with their advantages of high efficiency, low noise, and long lifespan, are widely used in new energy vehicles, industrial automation, smart homes, drones, and other fields. As the core structural component of a brushless motor, the housing not only needs to provide mechanical protection and heat dissipation, but its surface coating (usually rust-proof paint, insulating paint, or functional coating) must also have characteristics such as uniformity, strong adhesion, and stable thickness. Uneven coating will directly lead to a decrease in the rust-proof performance of the housing, differences in heat dissipation efficiency, and even affect the overall insulation safety of the motor. Therefore, the uniformity of the spraying process is one of the key factors that determine the quality of the brushless motor housing.

[0003] Manual spraying is a common method in small and medium batch production. It relies on operators holding spray guns and using simple tooling to fix and spray the casing. However, the coating quality of manual spraying is highly dependent on the operator's experience and skill. Different operators have different gun-holding angles, moving speeds, and rotation frequencies, resulting in large deviations in coating thickness for casings in the same batch. Therefore, a brushless motor casing spraying device is proposed to solve the above problems. Utility Model Content

[0015] 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.

[0016] Example: Refer to Figure 1-4A brushless motor housing spraying device includes a housing 1, a filter plate 2 fixedly installed inside the housing 1, an agitation assembly below the filter plate 2, a motor 12 fixedly installed on the top side of the housing 1, the output end of the motor 12 rotatably passing through the housing 1 and fixedly connected to a rotating rod 13, the other end of the rotating rod 13 being provided with a pressing assembly, a connecting plate 3 fixedly installed on one side of the housing 1, a placement assembly above the connecting plate 3, a transmission assembly and a spraying assembly respectively provided inside and on one side of the housing 1, the pressing assembly including a connecting box 14 fixedly connected to the bottom end of the rotating rod 13, an electric push rod 15 fixedly installed on the bottom inner wall of the connecting box 14, the output end of the electric push rod 15 passing through the connecting box 14 and fixedly connected to a pressure plate 16, the placement assembly including a groove 4 opened on the top side of the connecting plate 3, multiple sliding plates 5 slidably installed in the groove 4, the top sides of the multiple sliding plates 5 being fixedly connected to the same placement plate 6, anti-slip pads fixedly connected to the opposite surfaces of the placement plate 6 and the pressure plate 16, and the pressure plate 16 being provided. The housing to be painted is placed on the placement plate 6. Then, the electric push rod 15 is activated to move the pressure plate 16 downward. The pressure plate 16 and the placement plate 6 then work together to clamp the housing. Anti-slip pads are fixedly connected to the opposite surfaces of the pressure plate 16 and the placement plate 6. The two anti-slip pads can fit the housing better and play an anti-slip role, thereby preventing the housing from shifting during subsequent rotation. During the painting process, the motor 12 drives the rotating rod 13 to rotate. Since the connecting box 14 is fixedly connected to the bottom end of the rotating rod 13, the motor 12 will drive the connecting box 14 to rotate synchronously. During the rotation of the connecting box 14, the pressure plate 16 is always in a pressed state, so the housing can be rotated synchronously. During the rotation of the housing, the placement plate 6 will also drive the multiple sliding plates 5 fixedly connected to the bottom to slide in the sliding grooves 4 opened in the connecting plate 3, thereby ensuring the consistency of rotation and preventing the housing from coming out of the clamp during rotation.

[0017] Specifically, the transmission assembly includes a filter plate 2 with a circular hole, in which a transmission rod 18 is installed. The top end of the transmission rod 18 is rotatably connected to the inner wall of the top side of the housing 1. A first synchronous pulley 17 and a second synchronous pulley 19 are fixedly sleeved on the outer sides of the rotating rod 13 and the transmission rod 18, respectively. The first synchronous pulley 17 and the second synchronous pulley 19 share the same synchronous belt 20. A first bevel gear 21 is fixedly connected to the bottom end of the transmission rod 18, and the first bevel gear 21 meshes with a second bevel gear 23. The agitation assembly includes a rotating column 22 installed inside the housing 1. The two sides of the rotating column 22 are rotatably connected to the inner walls of the two sides of the housing 1, respectively. Multiple agitating plates 24 are fixedly connected to the outer side of the rotating column 22, and a second synchronous pulley 23 is fixedly sleeved on the outer side of the rotating column 22. The bevel gear 23 is fixedly sleeved with the first synchronous pulley 17 on the outside of the rotating rod 13. The first synchronous pulley 17 and the second synchronous pulley 19 share the same synchronous belt 20. Therefore, under the meshing transmission of the synchronous belt 20, the second synchronous pulley 19 will drive the transmission rod 18 connected to it to rotate synchronously. The first bevel gear 21 fixedly connected to the bottom end of the transmission rod 18 meshes with the second bevel gear 23 fixedly sleeved on the outside of the rotating column 22. Therefore, under the meshing transmission of the first bevel gear 21, the second bevel gear 23 will synchronously drive the rotating column 22 connected to it to rotate, thereby causing the multiple agitator plates 24 fixedly connected to the outside of the rotating column 22 to agitate the paint at the bottom of the box 1, so as to prevent the paint from clumping and affecting the normal operation of the water pump 7.

[0018] Specifically, the spraying assembly includes a water pump 7 fixedly installed on one side of the housing 1, an extraction pipe 8 fixedly installed on one side of the water pump 7, the other end of the extraction pipe 8 extending into the housing 1 and located below the filter plate 2, a delivery pipe 9 fixedly installed on the top side of the water pump 7, the other end of the delivery pipe 9 extending into the housing 1 and fixedly connected to a distribution box 10, the delivery pipe 9 being connected to the distribution box 10, and multiple nozzles 11 being provided on one side of the distribution box 10. With the water pump 7 installed, after the housing is clamped, the water pump 7 is started to drive the extraction pipe 8 to extract the paint below the housing 1, and then the paint is delivered from the delivery pipe 9 to the distribution box 10, and then sprayed onto the housing by the multiple nozzles 11 provided on one side of the distribution box 10. In conjunction with the operation of the motor 12, rotational spraying can be achieved.

[0019] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be any conventional known device, such as a computer, that can control the operation of the electrical components mentioned in the article.

[0020] In use: Place the machine casing to be sprayed on the placement plate 6, start the electric push rod 15, its output end drives the pressure plate 16 to move downwards. The pressure plate 16 cooperates with the placement plate 6 to clamp and fix the machine casing. Anti-slip pads are fixedly connected to the opposite surfaces of the pressure plate 16 and the placement plate 6. The two anti-slip pads can fit against the surface of the machine casing to prevent slippage and avoid displacement of the machine casing during subsequent rotation. After clamping, start the water pump 7. The water pump 7 draws the paint from the bottom of the box 1 through the extraction pipe 8. The paint is transported to the distribution box 10 through the delivery pipe 9, and then sprayed onto the machine casing by multiple nozzles 11 set on one side of the distribution box 10. During the spraying process, start the motor 12. The motor 12 drives the rotating rod 13 to rotate. Since the connecting box 14 is fixedly connected to the bottom end of the rotating rod 13, the motor 12 will drive the connecting box 14 to rotate synchronously when it runs. During the rotation, the pressure plate 16 The pressure is maintained at all times, thereby synchronously driving the casing to rotate. When the casing rotates, the placement plate 6 will drive the multiple sliding plates 5 fixedly connected to its bottom side to slide in the sliding groove 4 opened in the connecting plate 3, ensuring the consistency of rotation. At the same time, the first synchronous wheel 17 fixedly sleeved on the outside of the rotating rod 13 is connected to the second synchronous wheel 19 through the synchronous belt 20. Under the meshing action of the synchronous belt 20, the second synchronous wheel 19 drives the transmission rod 18 connected to it to rotate synchronously. The first bevel gear 21 fixedly connected to the bottom end of the transmission rod 18 meshes with the second bevel gear 23 fixedly sleeved on the outside of the rotating column 22. When the first bevel gear 21 rotates, it drives the second bevel gear 23 and the rotating column 22 to rotate synchronously. The multiple agitating plates 24 fixedly connected to the outside of the rotating column 22 rotate accordingly, agitating the paint at the bottom of the box 1 to prevent the paint from clumping and affecting the normal operation of the water pump 7.
