Description

Technical Field

[0001] This invention belongs to the field of water-cooled motor technology, and particularly relates to a water-cooling device for a vacuum motor. Background Technology

[0002] With technological advancements, an increasing number of devices require processing in a vacuum. For processing equipment operating continuously in a vacuum without water cooling, the lack of air prevents energy exchange through convection; heat dissipation relies solely on conduction and radiation. Continuous operation in a vacuum generates heat, leading to significant temperature rises in the mechanical structure of the moving platform. This can cause thermal deformation and affect other systems within the equipment, negatively impacting its overall precision. Motor heating is a primary cause of this temperature rise; therefore, water cooling devices must be installed in the motor within the vacuum environment to meet design specifications.

[0003] Existing water-cooled housings are generally divided into two main categories: integral and split. Integral housings are generally machined and cast. Split housings typically consist of two housings, with a first water channel and a second water channel respectively between them. When the two housings are overlapped to form a single unit, the corresponding first and second water channels form an integral threaded water channel or a U-shaped water channel.

[0004] While water-cooled split housings can achieve cooling water flow, they are complex to manufacture, prone to leakage, and require integration with other housings or covers to form a unified water-cooling system. Existing water-cooled monolithic housings have simple water channel distributions, either with cooling channels on only one side or multiple sides, but the number of channels is limited, failing to achieve comprehensive water-cooling coverage for more parts of the motor. Casting water-cooled monolithic housings is unsuitable for small-batch production due to high costs. Summary of the Invention

[0005] The purpose of this invention is to simplify the processing of water channels in the water-cooling structure of vacuum motors, while allowing for free setting of the number and arrangement of water channels to help different models of motors or other equipment achieve their design specifications through water cooling.

[0006] This invention provides a water-cooling device for a vacuum motor, comprising: a cooling cylinder, a circular cavity for placing the motor, a cooling water channel, an inlet water pipe connector, and an outlet water pipe connector. The positional relationship of each part is as follows: the circular cavity for placing the motor is located inside the cooling cylinder, the cooling water channel is located inside the cooling cylinder and is spaced apart from the circular cavity for placing the motor, and the cooling water flows out from the inlet water pipe connector through the cooling water channel and out from the outlet water pipe connector.

[0007] Beneficial effects:

[0008] This invention first addresses the shortcomings of existing separate housings that are prone to water leakage by combining the motor housing with the cooling housing. Through machining and partial welding, the water-cooling structure of the vacuum motor is integrally formed. While ensuring that the motor is water-cooled to the target temperature, the water channel processing is simpler, the water channel distribution is more extensive, and the water-cooling device is easier to install and disassemble. In addition, it is also suitable for water cooling of small motors.

[0009] In addition, unlike water cooling directly on the motor, this water cooling design is more flexible for the user. The design results can be iterated through simulation and experimentation. At the same time, the designer of the workpiece stage can flexibly design the water channels according to the temperature control requirements of the entire vacuum environment.

[0014] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0015] This invention provides a water-cooling device for a vacuum motor, the core improvements of which are: 1) the water-cooling structure is processed as a whole, without the need to process the water-cooling shell and the motor cover separately; 2) the water channels are processed in a simple and convenient way; and 3) the water-cooling coverage of the motor is wider.

[0016] Figure 1 A schematic diagram of a water-cooling device for a vacuum motor according to the present invention is shown. Figure 1As shown, the device includes: a cooling cylinder 1, a circular cavity 2 for placing the motor, a cooling water channel 3, a water inlet pipe connector 5, and a water outlet pipe connector 4. The positional relationship of each part is as follows: the circular cavity 2 for placing the motor is located inside the cooling cylinder 1, the cooling water channel 3 is located inside the cooling cylinder 1 and is separated from the circular cavity 2 for placing the motor, and the cooling water flows out from the water inlet pipe connector 5 through the cooling water channel 3 and out from the water outlet pipe connector 4, so as to realize water cooling of the motor in a vacuum.

[0017] Figure 1 The cooling water channel 3 shown is the end of the cooling water channel 3 that is sealed by a welded plug, that is, after the cooling water channel 3 is processed in the cooling cylinder 1, its end is sealed by welding a plug.

[0018] Figure 2 A cross-sectional view of the cooling water channel is shown.

[0019] In one embodiment, the cooling water channel 3 is spirally distributed along the outer wall of the circular cavity 2 where the motor is placed. Specifically, the cooling water channel 3 starts from the water inlet 5 of the circular cavity 2, spirals around the circular cavity 2 at a certain distance, and finally ends at the water outlet 4. The cooling water channel 3 may spiral around the circular cavity 2 seven or eight times. The water inlet 5 and the water outlet 4 may be located on the same side or opposite sides of the cooling cylinder 1.

[0020] In one embodiment, the cooling water channel 3 can be a pipe arranged along the inner wall of the cooling cylinder 1, with the inlet pipe joint 5 located on one side of the cooling cylinder 1 and the outlet pipe joint 4 located on the other side of the cooling cylinder 1. This results in the cooling water channel 3 having a spiral shape surrounding the circular cavity 2 where the motor is placed, when the cooling cylinder 1 is a cuboid. Here, "along" means arranged at a certain distance along the inner wall of the cooling cylinder 1, the distance being such that it can effectively cool the motor without hindering its operation.

[0021] In one implementation, Figure 1 The device shown may also include a cover plate 6 for covering the entire cooling cylinder 1 and protecting the internal structure. Figure 3 A schematic diagram of the welded joint of the cover plate is shown.

[0022] In one embodiment, two steps 7 are reserved at the connection of the cooling water channel 3 for placing the cover plate 6 and preventing the cover plate 6 from collapsing during welding. The connection of the cooling water channel 3 refers to the cooling water channel connecting groove 9, which is permanently connected to the front and rear spiral water channels in the cooling cylinder 1. In one embodiment, a cover plate welding port is provided on the outer wall of the cooling cylinder 1. The cover plate welding port can be located at any position in the cooling cylinder, as long as it is convenient to weld the cover plate. It can be located on the upper or lower wall of the cooling cylinder, and the number is determined according to the number of water channels. For example, if the water channel spirals 8 times and requires 7 cooling water channel connecting grooves 9, then 7 cover plate welding ports need to be set to seal the outer surface of the cooling cylinder, ensuring that the cooling water only flows out from the inlet pipe joint 5 through the cooling water channel 3 and out of the outlet pipe joint 4, and the water inside the water channel will not flow out. The cover plate welding port can be either circular or rectangular. A weld seam 8 can also be left at the weld joint of the cover plate to facilitate welding. Specifically, a notch is made at the welding end 101 on the cooling cylinder 1, which is the weld joint of the cover plate. The cooling cylinder 1 and the cover plate 6 are combined to form the weld seam 8, which facilitates the welding of the cooling cylinder 1 and the cover plate 6, so that the cooling cylinder 1 and the cover plate 6 form a whole.

[0023] The following describes the manufacturing process of cooling cylinder 1:

[0024] First, the outer shape of the cooling cylinder is machined. Then, cooling water channels 3, a circular cavity 2 for placing the motor, an inlet pipe connector 5, and an outlet pipe connector 4 are machined into the pre-machined cooling cylinder 1. After machining, the ends of the water channels are sealed by welding plugs. The top cover plate 6 of the cooling water channel 3 is connected to the cooling cylinder 1 by welding. The cover plate 6 seals the connection between the front and rear water channels of the spiral. Two steps 7 are reserved at the water channel connection of each cover plate 6 to place the cover plate 6 and prevent the cover plate 6 from collapsing during welding. A weld seam 8 is also left at the weld joint of the cover plate 6 to facilitate welding.
