Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for motor housing processing, and in particular to a support device for processing motor housings based on a double-cylinder cooling system. Background Technology

[0002] The twin-cylinder cooling motor achieves exponential optimization of motor heat flux density through a synergistic design of an inner-outer-cylinder nested structure and forced coolant circulation, making it widely used in new energy vehicles. The manufacturing process for the twin-cylinder cooling motor housing involves placing the inner cylinder inside the outer cylinder and then welding them together to create a housing suitable for twin-cylinder cooling motors (such as...). Figure 6 (As shown). To ensure the stability and safety of machining the dual-cylinder cooling motor housing, we urgently need a support device for machining the dual-cylinder cooling motor housing.

[0003] Currently, during the processing of twin-cylinder cooling motor housings, the inner cylinder is directly placed inside the outer cylinder before welding. However, due to the height difference between the inner and outer cylinders, if the inner cylinder is placed directly inside the outer cylinder, the end face of the inner cylinder will be lower than the end face. This welding operation will affect the processing accuracy of the twin-cylinder cooling motor housing, and consequently affect the pass rate of the twin-cylinder cooling motor housing. Utility Model Content

[0004] In view of the shortcomings of the existing production technology, the applicant provides a support device for machining a twin-cylinder cooling motor housing. By improving the structure of the support device, it is possible to ensure that the end face of the inner cylinder is flush with the end face of the outer cylinder after support, thereby improving the machining accuracy of the twin-cylinder cooling motor housing.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A support device for machining a twin-cylinder cooling motor housing includes: a support base, a plurality of first support portions, and a plurality of second support portions. The first support portions are located at the edge of the support base and connected to the support base. The plurality of first support portions are used together to support the outer cylinder of the twin-cylinder cooling motor housing, and the plurality of first support portions are used together to support the inner cylinder of the twin-cylinder cooling motor housing. The second support portions are located inside the first support portions and are threadedly connected to the support base to adjust the position of the second support portions relative to the support base so that the end face of the outer cylinder of the twin-cylinder cooling motor housing remains flush with the end face of the inner cylinder after support.

[0007] Therefore, when supporting the housing of the twin-cylinder cooling motor, the support position of the inner cylinder is adjusted by rotating the second support part to ensure that the end face of the inner cylinder is flush with the end face of the outer cylinder. Compared with the existing method of placing the inner cylinder directly without adjusting its position, this method has a simple structure and is easy to operate. By adjusting the position of the second support part relative to the support seat, the relative position of the outer cylinder and the inner cylinder of the twin-cylinder cooling motor can be adjusted to ensure that the end face of the inner cylinder is flush with the end face of the outer cylinder. Welding operations in this way can improve the processing accuracy of the twin-cylinder cooling motor housing, thereby improving the production qualification rate of the twin-cylinder cooling motor housing.

[0008] As a further improvement to the above technical solution: the first support part includes a first support rod and a first support block. The first support rod passes through the support seat and is threadedly connected to the support seat. The first support block is rotatably connected to the first support rod. Therefore, by rotating the first support rod, the position of the first support block relative to the support seat can be adjusted to adapt to different support requirements of the outer cylinder of different twin-cylinder cooling motors. Simultaneously, the center of gravity of the outer cylinder of the twin-cylinder cooling motor can be adjusted after support, further improving the stability of the outer cylinder support. Furthermore, since the first support rod is rotatably connected to the first support block, when the first support seat is adjusted, the first support seat only moves up and down without rotating. This ensures that during adjustment, the outer cylinder of the twin-cylinder cooling motor housing only moves up and down without rotating, thus ensuring the stability of the outer cylinder support. At the same time, the fact that the outer cylinder only moves up and down without rotating prevents it from touching the inner cylinder and causing displacement of the inner cylinder, further ensuring the machining accuracy of the twin-cylinder cooling motor housing.

[0009] As a further improvement to the above technical solution: an arc-shaped groove is formed on the side of the first support block away from the first support rod, and the arc-shaped groove is adapted to the contour line of the outer cylinder of the dual-cylinder cooling motor housing. Therefore, during support, the side wall of the outer cylinder of the dual-cylinder cooling motor housing abuts against the side wall of the arc-shaped groove, thus limiting the position of the outer cylinder of the dual-cylinder cooling motor housing and further improving the stability of the support for the outer cylinder of the dual-cylinder cooling motor housing.

[0010] As a further improvement to the above technical solution: the second support part includes a second support rod and a second support block. The second support rod passes through the support seat and is threadedly connected to the support seat. The second support block is rotatably connected to the second support rod. Therefore, by rotating the second support rod, the position of the second support block relative to the support seat can be adjusted to adapt to different support requirements of the inner cylinder of different twin-cylinder cooling motors. Simultaneously, the center of gravity of the inner cylinder of the twin-cylinder cooling motor can be adjusted after support, further improving the stability of the inner cylinder support. Furthermore, since the second support rod is rotatably connected to the second support block, when adjusting the second support seat, the second support seat only moves up and down without rotating. This ensures that during adjustment, the inner cylinder of the twin-cylinder cooling motor housing only moves up and down without rotating, thus ensuring the stability of the inner cylinder support. At the same time, the inner cylinder's vertical movement does not touch the outer cylinder, preventing displacement of the outer cylinder and further ensuring the machining accuracy of the twin-cylinder cooling motor housing.

[0011] As a further improvement to the above technical solution, the support base is a hollow structure. Therefore, since the end face of the outer cylinder of the dual-cylinder cooling motor housing is not a flat plane, the hollow support base facilitates the placement of the non-supported parts of the outer cylinder, ensuring that the supported outer cylinder of the dual-cylinder cooling motor housing remains horizontal.

[0012] As a further improvement to the above technical solution, it also includes: a base, which is connected to the support base via a third support rod.

[0013] As a further improvement to the above technical solution, it also includes: a third support part, which is located on one side of the base and is slidably connected to the base, and the third support part is used to support one side of the outer cylinder of the dual-cylinder cooling motor housing.

[0014] As a further improvement to the above technical solution, it also includes a fourth support portion, which is located on the other side of the base and slidably connected to the base. The fourth support portion is used to support the other side of the outer cylinder of the dual-cylinder cooling motor housing. Thus, through the cooperation of the third and fourth support portions, the outer cylinder of the dual-cylinder cooling motor housing can be supported from the side, ensuring that the outer cylinder of the dual-cylinder cooling motor housing will not shift, thereby further improving the stability of the support for the outer cylinder of the dual-cylinder cooling motor housing.

[0015] As a further improvement to the above technical solution: the structure of the fourth support part is the same as that of the third support part.

[0016] As a further improvement to the above technical solution: the third support part includes: a slider, an adjusting rod, a guide rod, a connecting rod, a third support block, and a limiting rod. The slider is slidably connected to the base. The adjusting rod and the guide rod are both located on one side of the slider. The adjusting rod passes through the base and is threadedly connected to the base. The adjusting rod is rotatably connected to the slider. The guide rod passes through the base and is slidably connected to the base. The adjusting rod is connected to the slider. The connecting rod, the third support block, and the limiting rod are all located on the other side of the slider. One end of the connecting rod is rotatably connected to the slider, and the other end of the connecting rod is connected to the third support block. The third support block is adapted to the outer cylinder of the dual-cylinder cooling motor housing. The limiting rod passes through the connecting rod and is inserted into the slider. The limiting rod is slidably connected to the connecting rod and the slider. Therefore, by rotating the adjusting rod, the slider is driven to move closer to the side of the twin-cylinder cooling motor housing. In this way, the side wall of the outer cylinder of the twin-cylinder cooling motor housing is supported by the third support block. The guide rod ensures that the slider's movement will not deviate. The connecting rod is rotatably connected to the slider and, in cooperation with the limiting rod, adjusts the position of the third support block to ensure that the third support block can rotate 180° to support the two end faces of the outer cylinder of the twin-cylinder cooling motor housing.

[0017] The beneficial effects of this utility model are as follows:

[0018] When supporting the housing of the twin-cylinder cooling motor, the support position of the inner cylinder is adjusted by rotating the second support part to ensure that the end face of the inner cylinder is flush with the end face of the outer cylinder. Compared with the existing method of placing the inner cylinder directly without adjusting its position, this method has a simple structure and is easy to operate. By adjusting the position of the second support part relative to the support seat, the relative position of the outer cylinder and the inner cylinder of the twin-cylinder cooling motor can be adjusted to ensure that the end face of the inner cylinder is flush with the end face of the outer cylinder. Welding operations in this way can improve the machining accuracy of the twin-cylinder cooling motor housing, thereby improving the production qualification rate of the twin-cylinder cooling motor housing.

[0019] This utility model also has the following advantages:

[0020] 1. In this utility model, when the outer cylinder of the dual-cylinder cooling motor housing is supported, the side wall of the outer cylinder abuts against the side wall of the arc-shaped groove. In this way, the outer cylinder of the dual-cylinder cooling motor housing can be limited, thereby further improving the stability of the support of the outer cylinder of the dual-cylinder cooling motor housing.

[0021] 2. The present invention uses a hollow support base to facilitate the placement of the non-supported parts of the outer cylinder of the dual-cylinder cooling motor housing, so as to ensure that the outer cylinder of the dual-cylinder cooling motor housing remains horizontal after support.

[0022] 3. Through the cooperation of the third and fourth support parts, this utility model can support the outer cylinder of the dual-cylinder cooling motor housing from the side, so as to ensure that the outer cylinder of the dual-cylinder cooling motor housing will not shift, thereby further improving the stability of the support of the outer cylinder of the dual-cylinder cooling motor housing.

[0039] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0040] like Figures 1 to 6 The diagram shows the preferred embodiment of this utility model. The support device for processing a twin-cylinder cooling motor housing in this embodiment includes: a support base 1, a plurality of first support parts 2, and a plurality of second support parts 3. The first support parts 2 are located at the edge of the support base 1 and are connected to the support base 1. The plurality of first support parts 2 are used together to support the outer cylinder of the twin-cylinder cooling motor housing and the inner cylinder of the twin-cylinder cooling motor housing. The second support parts 3 are located inside the first support parts 2 and are threadedly connected to the support base 1 to adjust the position of the second support parts 3 relative to the support base 1 so that the end face of the outer cylinder of the twin-cylinder cooling motor housing remains flush with the end face of the inner cylinder after support. Therefore, when supporting the housing of the twin-cylinder cooling motor, the support position of the inner cylinder is adjusted by rotating the second support part 3 to ensure that the end face of the inner cylinder is flush with the end face of the outer cylinder. Compared with the existing method of placing the inner cylinder directly without adjusting its position, this method has a simple structure and is easy to operate. By adjusting the position of the second support part 3 relative to the support seat 1, the relative position of the outer cylinder and the inner cylinder of the twin-cylinder cooling motor can be adjusted to ensure that the end face of the inner cylinder is flush with the end face of the outer cylinder. Welding operations in this way can improve the processing accuracy of the twin-cylinder cooling motor housing, thereby improving the production qualification rate of the twin-cylinder cooling motor housing.

[0041] In this embodiment, the first support part 2 includes a first support rod 201 and a first support block 202. The first support rod 201 passes through the support base 1 and is threadedly connected to the support base 1. The first support block 202 is rotatably connected to the first support rod 201. An arc-shaped groove 2021 is provided on the side of the first support block 202 away from the first support rod 201, and the arc-shaped groove 2021 is adapted to the contour line of the outer cylinder of the twin-cylinder cooling motor housing. Thus, by rotating the first support rod 201, the position of the first support block 202 relative to the support base 1 can be adjusted to adapt to the different support requirements of different twin-cylinder cooling motor outer cylinders. At the same time, the center of gravity of the twin-cylinder cooling motor outer cylinder after support can also be adjusted to further improve the stability of the twin-cylinder cooling motor outer cylinder support. In addition, since the first support rod 201 and the first support block 202 are rotatably connected, when the first support base 1 is adjusted, the first support base 1 only moves up and down and does not rotate. In this way, it can be ensured that the twin-cylinder cooling motor housing is stable during adjustment. The outer cylinder of the body only moves up and down without rotating, thus ensuring the stability of the outer cylinder support of the dual-cylinder cooling motor. At the same time, the outer cylinder of the dual-cylinder cooling motor housing only moves up and down without rotating, so that the up and down movement of the outer cylinder will not touch the inner cylinder and will not cause the inner cylinder to shift, thereby further ensuring the machining accuracy of the dual-cylinder cooling motor housing. When supported, the side wall of the outer cylinder of the dual-cylinder cooling motor housing abuts against the side wall of the arc groove 2021. In this way, the outer cylinder of the dual-cylinder cooling motor housing can be limited, thereby further improving the stability of the support of the outer cylinder of the dual-cylinder cooling motor housing.

[0042] It should be noted that the function of the first support part 2 is to adjust the position relative to the support seat 1 to adapt to the support of the outer cylinder of the dual-cylinder cooling motor housing of different models, to adapt to the support of the outer cylinder of the dual-cylinder cooling motor housing in both the upper and lower directions, to lower the center of gravity of the outer cylinder of the dual-tower cooling motor housing, and thus improve the stability of the support of the outer cylinder of the dual-tower cooling motor housing.

[0043] In this embodiment, the second support part 3 includes: a second support rod 301 and a second support block 302. The second support rod 301 passes through the support base 1 and is threadedly connected to the support base 1. The second support block 302 is rotatably connected to the second support rod 301. Therefore, by rotating the second support rod 301, the position of the second support block 302 relative to the support seat 1 can be adjusted to adapt to the different support requirements of the inner cylinder of different twin-cylinder cooling motors. At the same time, the center of gravity of the inner cylinder of the twin-cylinder cooling motor after support can also be adjusted to further improve the stability of the inner cylinder support. In addition, since the second support rod 301 and the second support block 302 are rotatably connected, when the second support seat 1 is adjusted, the second support seat 1 only moves up and down and does not rotate. This ensures that the inner cylinder of the twin-cylinder cooling motor housing only moves up and down during adjustment and does not rotate, thereby ensuring the stability of the inner cylinder support. At the same time, the inner cylinder of the twin-cylinder cooling motor housing only moves up and down and does not rotate, so that the up and down movement of the inner cylinder will not touch the outer cylinder and will not cause the outer cylinder to shift, thereby further ensuring the machining accuracy of the twin-cylinder cooling motor housing.

[0044] It should be noted that the second support part 3 has two functions: first, to adjust the position relative to the first support block 202 to ensure that the outer cylinder end face and the inner cylinder end face of the dual-cylinder cooling motor housing remain flush; second, to adjust the position relative to the support seat 1 to adapt to the support of the inner cylinder of different models of dual-cylinder cooling motor housings, to adapt to the support of the inner cylinder of the dual-cylinder cooling motor housing in both the upper and lower directions, to lower the center of gravity of the inner cylinder of the dual-tower cooling motor housing, and thus improve the stability of the support of the inner cylinder of the dual-tower cooling motor housing.

[0045] In this embodiment, the support base 1 is a hollow structure. Therefore, since the end face of the outer cylinder of the dual-cylinder cooling motor housing is not a flat plane, the hollow support base 1 facilitates the placement of the non-supported parts of the outer cylinder, ensuring that the supported outer cylinder of the dual-cylinder cooling motor housing remains horizontal.

[0046] In this embodiment, it also includes a base 4, which is connected to the support base 1 via a third support rod 401.

[0047] In this embodiment, it further includes: a third support part 5, which is located on one side of the base 4 and slidably connected to the base 4. The third support part 5 is used to support one side of the outer cylinder of the dual-cylinder cooling motor housing. The third support part 5 includes: a slider 501, an adjusting rod 502, a guide rod 503, a connecting rod 504, a third support block 505, and a limiting rod 506. The slider 501 is slidably connected to the base 4. The adjusting rod 502 and the guide rod 503 are both located on one side of the slider 501. The adjusting rod 502 passes through the base 4 and is threadedly connected to the base 4. The adjusting rod 502 and the slider 501 are connected to each other. The guide rod 503 is rotatably connected to the base 4 and is slidably connected to the base 4. The adjusting rod 502 is connected to the slider 501. The connecting rod 504, the third support block 505, and the limiting rod 506 are all located on the other side of the slider 501. One end of the connecting rod 504 is rotatably connected to the slider 501, and the other end of the connecting rod 504 is connected to the third support block 505. The third support block 505 is adapted to the outer cylinder of the double-cylinder cooling motor housing. The limiting rod 506 passes through the connecting rod 504 and is inserted into the slider 501. The limiting rod 506 is slidably connected to the connecting rod 504 and the slider 501. Therefore, through the cooperation of the third support part 5 and the fourth support part 6, the outer cylinder of the twin-cylinder cooling motor housing can be supported from the side of the outer cylinder, ensuring that the outer cylinder of the twin-cylinder cooling motor housing will not shift, thereby further improving the stability of the support of the outer cylinder of the twin-cylinder cooling motor housing; by rotating the adjusting rod 502, the slider 501 is driven to move closer to the side of the twin-cylinder cooling motor housing, thus supporting the side wall of the outer cylinder of the twin-cylinder cooling motor housing through the third support block 505; the guide rod ensures that the movement of the slider 501 will not shift; the connecting rod 504 is rotatably connected to the slider 501, and with the cooperation of the limiting rod 506, the position of the third support block 505 is adjusted to ensure that the third support block 505 can rotate 180°, so as to support the two end faces of the outer cylinder of the twin-cylinder cooling motor housing.

[0048] In this embodiment, it also includes: a fourth support part 6, which is located on the other side of the base 4 and is slidably connected to the base 4. The fourth support part 6 is used to support the other side of the outer cylinder of the dual-cylinder cooling motor housing. The structure of the fourth support part 6 is the same as that of the third support part 5.

[0049] The support process for the dual-cylinder cooling motor housing of this utility model is as follows: First, according to the model of the outer and inner cylinders of the dual-cylinder cooling motor housing to be processed, the position of the first support block 202 relative to the support seat 1 is adjusted by rotating the first support rod 201, and the position of the second support block 302 relative to the support seat 1 is adjusted by rotating the second support rod 301; next, the outer and inner cylinders of the dual-cylinder cooling motor housing are placed on the first support block 202 and the second support block 302 respectively (the side wall of the outer cylinder abuts against the arc groove 2021); then, the position of the third support block 505 is adjusted by rotating the adjusting rod 502 so that the third support block 505 is aligned with the dual-cylinder cooling motor housing. The outer cylinders are connected to each other; then, the outer cylinder of the dual-cylinder cooling motor housing is supported by the first support block 202 and the third support block 505, and the inner cylinder of the dual-cylinder cooling motor housing is supported by the second support block 302. The end faces of the outer cylinder and the inner cylinder of the dual-cylinder cooling motor housing are processed; finally, the outer cylinder and the inner cylinder of the dual-cylinder cooling motor housing are rotated 180°, and the outer cylinder of the dual-cylinder cooling motor housing is supported by the first support block 202 and the third support block 505, and the inner cylinder of the dual-cylinder cooling motor housing is supported by the second support block 302. The end faces of the outer cylinder and the inner cylinder of the dual-cylinder cooling motor housing are processed. In this way, the processing of the dual-cylinder cooling motor housing is completed.

[0050] In summary, when supporting the housing of the twin-cylinder cooling motor, this utility model adjusts the support position of the inner cylinder by rotating the second support part 3 to ensure that the end face of the inner cylinder is flush with the end face of the outer cylinder after adjustment. Compared with the existing method of placing the inner cylinder directly without adjusting its position, this method has a simple structure and is easy to operate. By adjusting the position of the second support part 3 relative to the support base 1, the relative position of the outer cylinder and the inner cylinder of the twin-cylinder cooling motor can be adjusted to ensure that the end face of the inner cylinder is flush with the end face of the outer cylinder. Welding operations in this way can improve the processing accuracy of the twin-cylinder cooling motor housing, thereby improving the production qualification rate of the twin-cylinder cooling motor housing.
