Description

Technical Field

[0001] This utility model relates to the field of tooling technology for machining drive motor housings, and more specifically, to integrated tooling for multi-faceted machining of drive motor housings. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as a power source or use conventional vehicle fuels and adopt new on-board power devices, integrating advanced technologies in vehicle power control and drive, forming automobiles with advanced technical principles, new technologies, and new structures. As the power component of new energy vehicles, the drive motor requires processing of its housing during the production and manufacturing process.

[0003] A search revealed that Chinese patent CN222680216U discloses a tooling for machining motor housings. This structure is equipped with a fixing mechanism to clamp and fix circular motor housings of different sizes, thereby facilitating subsequent machining operations such as grinding or drilling. By setting up a lifting mechanism, the height of the support plate can be freely adjusted, and the height of the motor housing can be flexibly adjusted according to different machining operations or machining devices.

[0004] However, in actual use, the end face and outer surface of the motor housing are easily obstructed by the placement plate, round plate and fixing plate during the clamping process, making it difficult to grind and drill the obstructed parts. This requires frequent adjustments by the operator, which is inconvenient. In view of this, this utility model proposes a multi-faceted machining integrated tooling for drive motor housing. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-faceted machining integrated tooling for drive motor housing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-faceted machining integrated tooling for a drive motor housing, including a base plate, a movable seat slidably mounted on the top of the base plate, a support seat provided on one side of the movable seat, and the support seat fixedly mounted on the surface of the base plate, a first rotary clamping structure mounted on the support seat, a second rotary clamping structure mounted on the movable seat, and a movable structure provided at the connection between the movable seat and the base plate.

[0007] It can be seen that this structure achieves multi-faceted machining of the motor housing by alternating clamping of two rotating clamping structures and driving of the moving structure, thereby improving machining efficiency.

[0008] To facilitate clamping the motor housing and rotating it during processing, enabling multi-faceted machining, the first rotary clamping structure preferably includes a support plate mounted on a support base. A rotating disk is rotatably mounted on the inner wall of the support plate. A rectangular groove is formed on the surface of the rotating disk, and a bidirectional threaded screw is rotatably mounted inside the rectangular groove. Two moving blocks are arranged outside the bidirectional threaded screw, and an arc-shaped clamping block is fixedly mounted at one end of each moving block. An adjusting block is fixedly mounted at the top of the bidirectional threaded screw. Both moving blocks are threadedly connected to the outer surface of the bidirectional threaded screw. The inner wall of the arc-shaped clamping block is lined with rubber. The first rotary clamping structure also includes a driven wheel located on the outer wall of the support plate and fixedly connected to the rotating disk. A driving wheel is provided at the bottom of the driven wheel and is rotatably connected to the outer wall of the support plate. A support frame is fixedly installed on the outer wall of the support plate, and a servo motor is installed on the support frame. The output end of the servo motor is fixedly connected to the driving wheel. A transmission belt is installed on the outside of both the driving wheel and the driven wheel. The first rotary clamping structure and the second rotary clamping structure are fixedly installed on the support base and the movable base, respectively. The structures of the first rotary clamping structure and the second rotary clamping structure are identical.

[0009] To facilitate clamping the left end of the motor housing or to allow the right end of the motor housing to detach from the second rotary clamping structure for processing, preferably, the movable structure has two sets of support blocks, both sets of support blocks are fixedly installed on the surface of the base plate, and each set of support blocks consists of two blocks. A rotating screw is rotatably installed between two of the support blocks, and a guide rod is fixedly installed between the other two support blocks. A rotary motor is provided at one end of the rotating screw, and the rotary motor is fixedly installed on the outer wall of one of the support blocks, with its output end fixedly connected to the rotating screw. The rotating screw and the guide rod are respectively threaded and slidably connected to the movable seat.

[0010] The technical effects and advantages of this utility model are as follows: 1. By setting up the first rotating clamping structure and the second rotating clamping structure in combination, the two ends of the motor housing can be clamped and fixed alternately, avoiding the difficulty in processing some areas of the motor housing due to obstruction. At the same time, the motor housing can be rotated easily to realize the processing of multiple sides of the outer wall of the motor housing, improving the comprehensiveness and convenience of processing. 2. By setting up a moving structure, the moving seat and the second rotary clamping structure can be precisely driven to move left and right. This provides stable power and guidance for the second rotary clamping structure to move closer to or away from the motor housing, to achieve alternating clamping, and to expose the covered parts of the motor housing. This ensures the smoothness and accuracy of the clamping switching process and improves processing efficiency.

[0011] In summary, this application, through the synergistic effect of the first rotary clamping structure, the second rotary clamping structure, and the moving structure, can avoid incomplete processing caused by clamping obstruction during the motor housing processing, achieving full processing of multiple sides and both ends of the motor housing, while improving the stability, convenience, and efficiency of the processing.

[0018] 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.

[0019] As attached Figure 1-5 The multi-faceted machining integrated tooling for the drive motor housing shown includes a base plate 1, a movable seat 2 slidably mounted on the top of the base plate 1, a support seat 3 provided on one side of the movable seat 2, and the support seat 3 fixedly mounted on the surface of the base plate 1. A first rotary clamping structure is mounted on the support seat 3, a second rotary clamping structure is mounted on the movable seat 2, and a movable structure is provided at the connection between the movable seat 2 and the base plate 1.

[0020] Specifically, in this structure, the right end of the circular drive motor housing is first clamped and fixed by the first rotating clamping structure on the support base 3. Then, the outer surface and left end of the motor housing are processed by the processing device. At the same time, during the processing of the motor housing, the first rotating clamping structure can rotate the motor housing and process multiple sides of the outer wall of the motor housing. Since the right end of the motor housing is clamped and fixed by the first rotary clamping structure, the part of the right end that is clamped or blocked is difficult to be fully processed. At this time, the moving structure is used to first drive the moving seat 2 to move closer to the support seat 3, so that the moving seat 2 drives the second rotary clamping structure to move closer to the left end of the motor housing and clamps and fixes the left end of the motor housing. After the left end of the motor housing is fixed by the second rotary clamping structure, the operator can release the clamping of the first rotary clamping structure on the right end of the motor housing. At this time, the moving structure drives the moving seat 2 away from the support seat 3, so that the right end of the motor housing, that is, the part that is clamped and blocked by the first rotary clamping structure, moves away from the first rotary clamping structure. At this time, the right end of the motor housing is exposed to the environment, and processing operations can be performed.

[0021] In this embodiment, as shown in the appendix Figure 1 , 2 As shown in Figures 3, 4, and 5, the first rotary clamping structure includes a support plate 4, which is mounted on a support base 3. A rotating disk 5 is rotatably mounted on the inner wall of the support plate 4. A rectangular groove 6 is formed on the surface of the rotating disk 5. A bidirectional threaded screw 7 is rotatably mounted inside the rectangular groove 6. Two moving blocks 8 are provided on the outside of the bidirectional threaded screw 7, and an arc-shaped clamping block 9 is fixedly mounted on one end of each of the two moving blocks 8. An adjusting block 10 is fixedly mounted on the top of the bidirectional threaded screw 7. Both moving blocks 8 are threadedly connected to the outside of the bidirectional threaded screw 7. A rubber anti-slip pad 11 is provided on the inner wall of the arc-shaped clamping block 9. The first rotary clamping structure also includes a driven wheel 12. The driven wheel 12 is located on the outer wall of the support plate 4 and is fixedly connected to the rotating disk 5. The bottom of the driven wheel 12 is provided with a driving wheel 13, which is rotatably connected to the outer wall of the support plate 4. A support frame 14 is fixedly installed on the outer wall of the support plate 4. A servo motor 15 is installed on the support frame 14, and the output end of the servo motor 15 is fixedly connected to the driving wheel 13. A transmission belt 16 is installed on the outside of the driving wheel 13 and the driven wheel 12. The first rotary clamping structure and the second rotary clamping structure are fixedly installed on the support base 3 and the moving base 2, respectively. The structures of the first rotary clamping structure and the second rotary clamping structure are the same.

[0022] Specifically, in this structure, the first rotary clamping structure cannot move on the support base 3, while the second rotary clamping structure can move left and right on the movable base 2. The first and second rotary clamping structures have the same structure and the same principle. Taking the first rotary clamping structure as an example, in specific operation, one end of the motor housing is placed between two arc-shaped clamping blocks 9. By rotating the adjusting block 10, the bidirectional threaded screw 7 rotates inside the rectangular groove 6. The rotation of the bidirectional threaded screw 7 drives the two moving blocks 8 to move closer to each other, and then clamps the motor housing through the two arc-shaped clamping blocks 9. The rubber anti-slip pad 11 at the arc-shaped clamping block 9 improves the clamping effect. During the processing of the motor housing, the servo motor 15 mounted on the support frame 14 can drive the drive wheel 13 to rotate on the outer wall of the support plate 4. Under the action of the transmission belt 16, the driven wheel 12 drives the rotary disk 5 to rotate, thereby rotating the clamped motor housing and realizing the multi-face processing operation of the motor housing. It is worth noting that in the first and second rotary clamping structures, the connection between the driven wheel 12, the driving wheel 13 and the transmission belt 16 has a certain tension. The driven wheel 12 is larger and the driving wheel 13 is smaller. In actual use, there will be no slippage or detachment. This can meet the requirement that the driving wheel 13 drives the driven wheel 12 to rotate through the transmission belt 16.

[0023] In this embodiment, as shown in the appendix Figure 1 As shown, the movable structure has two sets of support blocks 17, both sets of support blocks 17 are fixedly installed on the surface of the base plate 1, and each set of support blocks 17 has two blocks. A rotating screw 18 is rotatably installed between the two support blocks 17, and a guide rod 19 is fixedly installed between the other two support blocks 17. A rotary motor 20 is provided at one end of the rotating screw 18. The rotary motor 20 is fixedly installed on the outer wall of one of the support blocks 17, and its output end is fixedly connected to the rotating screw 18. The rotating screw 18 and the guide rod 19 are respectively threaded and slidably connected to the movable seat 2.

[0024] Specifically, in this structure, when the movable seat 2 drives the second rotary clamping structure to move left and right on the base plate 1, firstly, the rotary motor 20 drives the rotary lead screw 18 to rotate between the two corresponding support blocks 17, so that the movable seat 2 moves left and right on the surface of the base plate 1 under the sliding guidance of the guide rod 19, driving the second rotary clamping structure to move closer to or further away from the first rotary clamping structure, so as to facilitate clamping the left end of the motor housing, or to make the right end of the motor housing detach from the second rotary clamping structure for processing operations.

[0025] To facilitate understanding of the working principle of this application, the working principle of this application will be explained in detail below.

[0026] Working principle of this utility model: This application provides an integrated tooling for multi-face machining of drive motor housings, which can facilitate multi-face machining operations on drive motor housings in new energy vehicles. In specific operation, the right end of the circular drive motor housing is clamped and fixed by the first rotating clamping structure on the support base 3. Specifically, the bidirectional threaded screw 7 is rotated by rotating the adjusting block 10, which drives the two moving blocks 8 and the arc-shaped clamping block 9 to move closer to each other. The rubber anti-slip pad 11 clamps the right end of the motor housing. Subsequently, the machining device processes the outer surface and left end of the motor housing. At the same time, the servo motor 15 drives the drive wheel 13 to rotate, which drives the driven wheel 12 and the rotating disk 5 to rotate through the transmission belt 16, thereby realizing multi-face machining of the outer wall of the motor housing. When the right end of the motor housing is difficult to process due to being blocked by the first rotary clamping structure, the moving structure is activated. The rotary motor 20 drives the rotary screw 18 to rotate, causing the moving seat 2 to move closer to the support seat 3 under the guidance of the guide rod 19. The second rotary clamping structure on the moving seat 2 then moves closer to the left end of the motor housing and clamps it. Its clamping principle is the same as that of the first rotary clamping structure. After the second rotary clamping structure fixes the left end of the motor housing, the clamping of the right end by the first rotary clamping structure is released. Then, the moving structure drives the moving seat 2 away from the support seat 3, so that the right end of the motor housing is freed from the cover of the first rotary clamping structure and exposed. At this time, the right end can be processed. During the processing, the second rotary clamping structure can drive the motor housing to rotate, completing the multi-face processing of the right end.
