[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Embodiment: This embodiment provides a new disc motor end cover water channel structure, see Figure 1 - Fig.14Specifically, it includes an end cover body 1, a first installation position 101 is opened around the end cover body 1, and a water channel base 102 is placed in the first installation position 101, a uniformly distributed water flow channel 103 is opened in the water channel base 102, and one side of the water flow channel 103 penetrates to the outer surface of the end wall of the water channel base 102, and two threaded through holes 104 corresponding to the two end positions of the water flow channel 103 are opened on the water channel base 102, and a water nozzle 105 is screwed in each threaded through hole 104, and a first water channel 103 extending outside the first installation position 101 is opened around the end cover body 1. There are two mounting positions 106, and a cover plate 107 matching the internal size is placed in the second mounting position 106, the cover plate 107 is tightly pressed on the waterway base 102, the cover plate 107 is firmly connected to the end cover body 1 by bolts distributed around, a through groove 108 corresponding to the two threaded through holes 104 is opened on the cover plate 107, the water nozzle 105 extends to the outside through the through groove 108, the water flow channel 103 is opened in the waterway base 102 in a spiral structure, the number of spiral windings of the water flow channel 103 is three, and the opening of the water flow channel 103 avoids the mounting hole on the end cover body 1.

[0021] When the device is actually used, it is installed at the end position of the disc motor, and the side of the end cover body 1 away from the cover plate 107 faces the stator in the disc motor, and the cover plate 107 is exposed on the outside of the disc motor. The water supply end and the water return end of the external cooling water supply hose are respectively connected to two water nozzles 105. The cooling water enters the water flow channel 103 opened in the water channel base 102 through a water nozzle 105 under the connection of the threaded through hole 104, and is then discharged through the water nozzle 105 connected to the threaded through hole 104 at the other end, forming a state in which the cooling water circulates in the water flow channel 103, quickly taking out the heat generated by the work in the disc motor, and performing a heat dissipation operation on the disc motor.

[0022] In the disc motor in the prior art, the water flow channel 103 for circulating cooling water is usually directly opened in the end cover body 1. Due to the complex shape and structure of the water flow channel 103, the process of directly designing and processing it in the end cover body 1 is complicated and difficult. Especially in the early stage of the design of the disc motor, when making manual samples of the disc motor, how to achieve convenient processing of the water flow channel 103 in the end cover body 1 and avoid water leakage is a huge problem, which leads to a significant increase in the cost of design and production. In the technical solution of the present application, the water flow channel 103 is opened on the water channel base 102, and the water channel base 102 is movably installed in the first installation position 101 opened in the end cover body 1, and is firmly installed and pressed in the first installation position 101 by the cover plate 107, which makes the water channel base 102 loaded with the water flow channel 103 flexibly separable from the end cover body 1.

[0023] In the actual processing process, the staff can perform separate processing and production on the end cover body 1, the water channel base 102 and the cover plate 107. In the process of processing and producing the end cover body 1, the first installation position 101 for installing the water channel base 102 and the second installation position 106 for installing the cover plate 107 are directly formed on the end cover body 1. In the process of processing and producing the water channel base 102, the open-style water flow channel 103 is directly milled out on the water channel base 102, which can effectively improve the convenience of processing and forming the water flow channel 103, and is conducive to reducing the processing difficulty and processing cost of the water flow channel 103. After the water flow channel 103 is formed in the water channel base 102, the staff embeds the water channel base 102 into the first installation position 101, and embeds the cover plate 107 into the second installation position 106. After fastening and installation, The cover plate 107 cooperates with the first installation position 101 to clamp the water channel base 102 in the first installation position 101, so that the water flow channel 103 opened on the water channel base 102 is in a closed state, thereby realizing the sealing operation of the water flow channel 103, and the processing and subsequent installation are convenient, and the sealing of the water flow channel 103 can be effectively guaranteed. Different from the process of traditional disc motors that directly forms the water flow channel 103 in the end cover body 1, the processing of the water flow channel 103 in the present application can be completed on the water channel base 102, and the end cover body 1 is separated from the processing process, thereby avoiding the difficulties caused by directly processing the water flow channel 103 on the end cover body 1. This form can not only facilitate the processing of manual prototypes of disc motors, but also can be used for efficient production when it is subsequently applied to mass production, which is beneficial to greatly improve the production efficiency of disc motors.

[0024] In the specific implementation process, Figure 1 , Figure 5 and Fig. 9 As shown, the side of the water flow channel 103 facing the first installation position 101 penetrates to the outer surface of the end wall of the water channel base 102, and the outer side of the water channel base 102 is movably sleeved with a ring shell 2 adapted to its outer size, and the ring shell 2 covers the water flow channel 103, and the outer size of the ring shell 2 is adapted to the inner size of the first installation position 101. A first ring groove 201 is opened around the outer cylindrical surface of the water channel base 102, and a first metal sealing ring 202 that is tightly fitted with the outer annular end wall of the ring shell 2 is installed in the first ring groove 201. A second annular groove 203 is formed on the inner annular end wall of the waterway base 102, and a second metal sealing ring 204 is installed in the second annular groove 203, which is tightly fitted with the inner cylindrical surface of the waterway base 102. The first metal sealing ring 202 is movably installed in the first annular groove 201, and the second metal sealing ring 204 is movably installed in the second annular groove 203. The first metal sealing ring 202 and the second metal sealing ring 204 are both provided with through notches, and the cross-sections of the first metal sealing ring 202 and the second metal sealing ring 204 are both set to S-shaped structures.

[0025] When the device is actually used, since the annular shell 2 is provided to be sleeved on the outer side of the water channel base 102, the water flow channel 103 opened on the water channel base 102 can be in a closed state when it is not installed in the first installation position 101 by means of the covering of the annular shell 2 on the water channel base 102. The water channel base 102 and the annular shell 2 cooperate with each other, which can effectively improve the overall sealing of the water flow channel 103. In order to further improve the sealing of the water flow channel 103 by the annular shell 2 covering the water channel base 102, the water channel base 102 and the annular shell 2 are provided. A first metal sealing ring 202 and a second metal sealing ring 204 are arranged between the shell 2 to improve the sealing performance. A through notch is arranged on the first metal sealing ring 202 and the second metal sealing ring 204, so that the first metal sealing ring 202 and the second metal sealing ring 204 can be opened outward through the opening after being stressed, so that the staff can install the first metal sealing ring 202 in the first annular groove 201 and the second metal sealing ring 204 in the second annular groove 203 more conveniently. At the same time, the first metal sealing ring 202 and the second metal sealing ring 204 are The existence of the notches on the sealing ring 202 and the second metal sealing ring 204, combined with the elastic deformation characteristics of their own metal materials, enables the first metal sealing ring 202 and the second metal sealing ring 204 to always maintain a tendency to expand outward. When the first metal sealing ring 202 and the second metal sealing ring 204 are squeezed and the notches are closed, the outer side of the first metal sealing ring 202 can be tightly fitted with the outer annular end wall of the ring shell 2, and the outer side of the second metal sealing ring 204 can be tightly fitted with the inner cylindrical surface of the water channel base 102. The cross-sections of the first metal sealing ring 202 and the second metal sealing ring 204 are set to an S-shaped structure. Under the elastic deformation characteristics of their own metal materials, the first metal sealing ring 202 can be tightly filled in the first annular groove 201, and the second metal sealing ring 204 can be tightly filled in the second annular groove 203. Under the cooperation of the above structures, the sealing stability between the water channel base 102 and the ring shell 2 can be effectively guaranteed, thereby preventing the cooling water flowing in the water flow channel 103 from leaking outward, so that the water flow channel 103 is in a sealed and stable state.

[0026] In the specific implementation process, Figure 1 and Fig. 9As shown, an annular mounting position 3 is provided around the inner and outer sides of the first mounting position 101, and an O-ring 301 is installed in the annular mounting position 3. When the device is actually used, a plurality of evenly distributed mounting holes can be provided in the first mounting position 101, and the bolts inserted in the mounting holes are used to fix the stator in the disc motor. Due to the existence of these mounting holes, the first mounting position 101 is connected to the inside of the disc motor. Therefore, in order to avoid the disc motor being poorly sealed due to the mounting holes provided at the first mounting position 101, the annular mounting position 3 is provided around the inner and outer sides of the first mounting position 101, so that the stator in the first mounting position 101 is fixed. The numerous mounting holes are located between the inner and outer annular mounting positions 3, and cooperate with the O-ring 301 installed in the annular mounting position 3, and the O-ring 301 is squeezed after the waterway base 102 and the annular shell 2 are combined and embedded in the first mounting position 101, so that the O-ring 301 elastically deforms and fills the gap to seal the first mounting position 101. When the waterway base 102 and the annular shell 2 are combined and pressed into the first mounting position 101 by the cover plate 107, under the relative action, the O-ring 301 can provide support for the annular shell 2, thereby ensuring the stability of the waterway base 102 and the annular shell 2 combined and installed in the first mounting position 101.

[0027] In the specific implementation process, as shown in the figure and the figure, a plurality of surrounding positioning blocks 4 are fixedly installed on the side of the outer cylindrical surface of the waterway base 102 close to the cover plate 107, a first positioning groove 401 adapted to the positioning block 4 is opened on the outer annular end wall of the ring shell 2, and a second positioning groove 402 adapted to the positioning block 4 is opened in the second installation position 106. When the device is actually used, after the waterway base 102 and the ring shell 2 are combined, the positioning block 4 fixedly installed on the waterway base 102 will be embedded in the outer annular end wall of the ring shell 2. The first positioning groove 401 opened on the waterway base 102 and the annular shell 2 allows the waterway base 102 and the annular shell 2 to maintain a relatively stable state after being combined. When the waterway base 102 and the annular shell 2 are installed in the first installation position 101 after being combined, the outer end of the positioning block 4 will be embedded in the second positioning groove 402 opened in the second installation position 106, so as to locate the position of the waterway base 102 and the annular shell 2 installed in the first installation position 101, which is beneficial to ensure the stability of the waterway base 102 and the annular shell 2 after being installed in the first installation position 101.

[0028] In the specific implementation process, Figure 6 , Fig.12 and Fig.14As shown, an adapter 5 is further connected between the threaded through hole 104 and the water nozzle 105, and the adapter 5 includes a shaft seat 501 set as a concave structure, and two coaxial and symmetrically arranged hollow shafts 502 are fixedly installed on the shaft seat 501, and an adjustment block 503 set as a convex structure is rotatably connected to the shaft seat 501 through the hollow shaft 502, and pipe joints 504 set corresponding to the two threaded through holes 104 are fixed side by side on the end wall of the shaft seat 501 away from the adjustment block 503, and the pipe joints 504 are fixed side by side. A first channel 505 provided in the shaft seat 501 is connected between the hollow shaft 502 and the corresponding hollow shaft 502, two second channels 506 are provided in the adjustment block 503, and the two second channels 506 are respectively connected with the two first channels 505, the inner diameter of the outer end of the second channel 506 is matched with the inner diameter of the threaded through hole 104, an external threaded tube 507 is rotatably sleeved on the outer side of the pipe joint 504, and a force application disk 508 is fixedly installed on the outer side of the end of the external threaded tube 507 close to the shaft seat 501.

[0029] When the device is actually used, by installing the adapter 5 between the threaded through hole 104 and the water nozzle 105, the position and direction of the water nozzle 105 can be flexibly adjusted by means of the relative rotation of the shaft seat 501 and the adjustment block 503. With the rotation of the adjustment block 503, the water nozzle 105 can be adjusted in the up and down directions of 0°~180°, so that the direction of the water nozzle 105 is adapted to the access direction of the cooling water supply hose, which can avoid the cooling water supply hose from bending and flattening due to the inability to adjust the direction of the water nozzle 105, which is beneficial to ensuring the smooth and stable supply of cooling water. The water nozzle 105 is installed in the outer end of the second channel 506 by means of threaded connection, and the external threaded barrel 507 is also connected to the threaded through hole 104 by means of threaded connection, which allows the staff to choose whether to install the adapter 5 according to actual needs.

[0030] When the adapter 5 is connected between the threaded through hole 104 and the water nozzle 105, the cooling water enters through one of the water nozzles 105 into the second channel 506, the hollow shaft 502, the first channel 505, the pipe joint 504, and the threaded through hole 104, which are on the same side and interconnected. After flowing in the water flow channel 103, the cooling water is discharged through the threaded through hole 104, the pipe joint 504, the first channel 505, the hollow shaft 502, the second channel 506 and the water nozzle 105 arranged on the other side. Two relatively independent water flow channels are formed in the adapter 5, which are respectively connected between the two threaded through holes 104 and the two water nozzles 105, so as to ensure the stability of cooling water supply and reflux.

[0031] In the specific implementation process, Figure 6 and Fig.14As shown, one side of the shaft seat 501 close to the adjustment block 503 and one side of the adjustment block 503 close to the shaft seat 501 are both set to be arc surfaces coaxial with the hollow shaft rod 502, and grooves 509 evenly distributed around the hollow shaft rod 502 are opened on the arc surface of the shaft seat 501, and a clamping block 510 adapted to the groove 509 is fixedly mounted on the adjustment block 503. When the device is actually used, in the process of changing the direction of the water nozzle 105 by rotating the adjustment block 503, the clamping block 510 fixedly installed on the adjustment block 503 is always engaged in the grooves 509 distributed around the arc surface of the shaft seat 501, and with the help of the engagement resistance between the grooves 509 and the clamping block 510, the adjustment block 503 can maintain a stable state after rotation adjustment.

[0032] Specifically, the working principle and operation method of the present invention are as follows: The end cover body 1, the water channel base 102 and the cover plate 107 are set in a separable style, so that the water flow channel 103 designed on the water channel base 102 can be processed in an open manner independently of the end cover body 1, which improves the processing convenience of the water flow channel 103. The water channel base 102 is pressed into the first installation position 101 by the cover plate 107 in cooperation with the end cover body 1, so that the water flow channel 103 is in a stable and closed state. At the same time, the ring shell 2 is sleeved on the outside of the water channel base 102 to cover the water flow channel 103 opened on the water channel base 102, and the first metal sealing ring 202 and the second metal sealing ring 204 are installed in the water channel. Between the base 102 and the annular shell 2, with the help of the elastic filling of the first metal sealing ring 202 and the second metal sealing ring 204, the sealing stability between the water channel base 102 and the annular shell 2 is ensured, thereby preventing the cooling water flowing in the water flow channel 103 from leaking outward, and further improving the sealing of the water flow channel 103. By installing the adapter 5 between the threaded through hole 104 and the water nozzle 105, with the help of the relative rotation of the shaft seat 501 and the adjustment block 503, the position and direction of the water nozzle 105 can be flexibly adjusted, thereby avoiding the cooling water supply hose from bending and flattening due to the inability to adjust the direction of the water nozzle 105, thereby ensuring smooth and stable supply of cooling water.

[0033] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
