Description
Technical Field
[0001] This utility model relates to the technical field of motor housing cutting devices, specifically an environmentally friendly cutting device for processing motor housings. Background Technology
[0002] During the manufacturing process of motor housings, cutting is an essential step. Cutting precisely removes material in three-dimensional space and can accommodate irregularly shaped motor housings, ranging from cylindrical (general motors) to polygonal pyramidal (flat wire motors for new energy vehicles). This ensures that the structure meets the usage requirements, guarantees the precise fit between key components such as bearing holes and stator slots and the rotor and windings, and avoids operational risks such as vibration noise and abnormal temperature rise caused by fit clearance errors.
[0003] Utility model patent CN208601182U discloses a motor housing cutting device. Its structure includes a worktable, a cutting mechanism, a power mechanism, and a control system. The cutting mechanism includes a moving platform, a guide rail, a slider, and a second fixed plate. A positioning disc and a column are mounted on the upper end of the second fixed plate. A positioning bracket is mounted on the front side of the positioning disc. A first fixed plate is connected to the top of the column. A first hydraulic cylinder is mounted on the upper middle part of the first fixed plate. A first lead screw, passing through the first fixed plate, is connected to the lower end of the first hydraulic cylinder. The lower end of the first lead screw is fixedly connected to a clamping plate. A cutter head is mounted at the front end of the power mechanism. In summary, this cutting device is an automated device with high production efficiency and excellent cutting effect. It requires minimal manpower, greatly reducing production costs. Furthermore, it is simple to operate and suitable for large-scale production and promotion.
[0004] However, the above-mentioned device requires the motor housing to be placed on the positioning disc and the positioning bracket to be clamped onto the motor housing during use. Furthermore, the motor housing needs to be pressed down and fixed during cutting using a clamping plate. This fixing method not only obstructs the motor housing significantly, potentially interfering with the smooth operation of the cutting mechanism, but also prevents the motor housing from rotating to change its orientation towards the cutting mechanism's machining surface. In summary, the above fixing method is not conducive to effective cutting. The entire motor housing machining process requires multiple loading and unloading operations to switch between different machining surfaces, resulting in low working efficiency and cumbersome operation for workers. Therefore, to address these issues, an environmentally friendly cutting device for motor housing machining is proposed. Utility Model Content
[0005] The technical problem this utility model aims to solve is to provide an environmentally friendly cutting device for motor housing processing. This motor housing cutting device uses a hook-claw type housing fixing mechanism to position and install the motor housing, facilitating efficient cutting by the cutting mechanism. In the hook-claw type housing fixing mechanism, the movable pull ring can slide freely, allowing the hook-claw positioning pull rod installed on it to lock onto the port of motor housing of different sizes and tighten and fix it. Since the hook-claw positioning pull rod only has a small contact area with the motor housing at the port, it hardly obstructs the outer wall of the motor housing, facilitating smooth cutting. At the same time, since the hook-claw type housing fixing mechanism is rotatably mounted on the top of the sliding bracket, it can drive the motor housing to rotate at any angle, facilitating continuous cutting without the need for repeated loading and unloading of the motor housing to change its orientation, significantly improving work efficiency. This solves the technical problem in the comparative technology where the motor housing fixing method not only obstructs the motor housing to a large extent but also prevents the motor housing from changing its orientation to the processing surface of the cutting mechanism by rotation, requiring multiple loading and unloading during the entire motor housing processing process, resulting in low cutting efficiency and cumbersome operation for workers.
[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:
[0007] An environmentally friendly cutting device for processing motor housings includes a guide base plate with a sliding bracket slidably mounted thereon, a hook-type housing fixing mechanism rotatably mounted on top of the sliding bracket for mounting and positioning the motor housing to be cut, a rotation drive mechanism for driving the hook-type housing fixing mechanism to rotate, and a cutting mechanism for cutting the motor housing. The hook-type housing fixing mechanism includes a grooved shaft cylinder with a tray mounted on its rear side, on which a movable pull ring is slidably mounted. Several hook-type positioning pull rods are rotatably mounted on the movable pull ring. Simultaneously, a tensioning rod is provided inside the grooved shaft cylinder for pulling the movable pull ring to slide, thereby fixing the hook-type housing. The positioning lever hooks onto the motor housing port and pulls it tight to secure it to the tray. In the hook-claw type housing fixing mechanism, the movable pull ring can slide freely, allowing the hook-claw positioning lever installed on it to lock onto the motor housing port of different sizes and pull it tight to fix it. Since the hook-claw positioning lever only has a small contact area with the motor housing at the port, it will hardly obstruct the outer wall of the motor housing, which facilitates the smooth progress of the cutting work. At the same time, the rotation drive mechanism can drive the motor housing to rotate at any angle, which facilitates the continuous operation of the cutting work. There is no need to repeatedly load and unload the motor housing to change its orientation, which can significantly improve work efficiency.
[0008] In one possible implementation, the grooved shaft cylinder has several sliding grooves, and the movable pull ring includes a sliding ring body that is slidably sleeved on the grooved shaft cylinder. Several connecting sliders that slide in the sliding grooves are fixedly arranged on the inner wall of the sliding ring body. A transmission ring is fixedly connected to the inner end of the connecting slider. Through the above structure, the transmission ring and the sliding ring body can be fixedly connected, thereby enabling the sliding ring body to move synchronously when the transmission ring is driven.
[0009] In one possible implementation, the tensioning rod includes a threaded rod that is threaded to the rear end of the grooved shaft. Its front end passes through the transmission ring and is fixedly connected to a pressure plate. A compression spring connected to the transmission ring is fixedly installed on the rear end face of the pressure plate. When the threaded rod is turned, it will drive the pressure plate to move, thereby pushing the transmission ring to slide, thus driving the sliding ring body to slide. The compression spring can apply tension to the threaded rod when the turning of the threaded rod stops, so that the thread engagement is tight and not easy to loosen.
[0010] In one possible implementation, the hook positioning rod includes an elastic folding rod, the rear end of which is rotatably connected to the sliding ring body via a hinge joint, and the front end of which is fixedly provided with a fork. A rotatable hook head is installed in the fork via a rotating shaft. The hook head is provided with two locking blocks for locking the motor housing. The above structure can realize the movable connection of the elastic folding rod, so that it can be adapted to motor housings of different sizes by rotation, while the hook head is used to lock the port of the motor housing and fix it.
[0011] In one possible implementation, a mating plate is fixedly connected to the outer end of the rotating shaft, and a reset torsion spring is provided on the outer sleeve of the rotating shaft. The two ends of the reset torsion spring are fixedly connected to the mating plate and the fork, respectively. Based on the above technical solution, the reset torsion spring can apply a reset torque to restore the hook to its original position when no external force is applied, thus avoiding the inconvenience of operation caused by the free rotation of the hook when it is snapped onto the motor housing port.
[0012] In one possible implementation, the rotation drive mechanism includes a transmission wheel and a drive wheel, and also includes a stepper motor mounted on a sliding bracket. The drive wheel is mounted on the end of the stepper motor shaft, and the transmission wheel is mounted on the end of the grooved shaft. The transmission wheel and the drive wheel are connected by a transmission belt. When it is necessary to drive the motor housing to rotate, the stepper motor drives the drive wheel to rotate, which in turn drives the transmission wheel to rotate under the transmission action of the transmission belt, ultimately driving the grooved shaft to rotate, thereby driving the motor housing.
[0013] In one possible implementation, the cutting mechanism includes a guide rail, a sliding table is slidably mounted thereon, and an adjustable distance motor is installed at the end of the guide rail. The output shaft of the adjustable distance motor is fixedly connected to a lead screw, which is threadedly connected to the sliding table. A support frame is installed on the sliding table, and a cutting motor is mounted on it. The output shaft of the cutting motor is fixedly connected to a cutting disc. By driving the lead screw to rotate through the adjustable distance motor, the sliding table can be slidably adjusted to adjust the distance between the cutting motor and the motor housing. During cutting, the cutting motor drives the cutting disc to rotate to complete the cutting process.
[0014] In one possible implementation, the guide base plate is provided with several guide grooves, and the lower end face of the sliding bracket is fixedly provided with several protrusions corresponding to the guide grooves. The above structure enables the sliding bracket to slide in an directional manner, thereby enabling the motor housing to be pushed in an directional manner during the cutting process, which facilitates the smooth progress of the cutting work.
[0015] In summary, this utility model has the following beneficial technical effects:
[0016] This motor housing cutting device uses a hook-claw type housing fixing mechanism to position and install the motor housing, which facilitates efficient cutting by the cutting mechanism. In the hook-claw type housing fixing mechanism, the movable pull ring can slide freely, allowing the hook-claw positioning pull rod installed on it to lock the port of motor housing of different sizes and tighten and fix it. Since the hook-claw positioning pull rod only has a small contact area with the motor housing at the port, it will hardly obstruct the outer wall of the motor housing, which facilitates the smooth progress of the cutting work.
[0017] Meanwhile, since the hook-type housing fixing mechanism is rotatably mounted on the top of the sliding bracket, it can drive the motor housing to rotate at any angle, which facilitates continuous cutting work and eliminates the need to repeatedly install and remove the motor housing to change its orientation, thus significantly improving work efficiency.

[0026] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:
[0027] like Figure 1 - Figure 2As shown, this embodiment provides an environmentally friendly cutting device for processing motor housings, including a guide base plate 1 on which a sliding bracket 2 is slidably mounted; a hook-type housing fixing mechanism 3, rotatably mounted on the top of the sliding bracket 2, used to install and position the motor housing 4 to be cut; a rotation drive mechanism 5, used to drive the hook-type housing fixing mechanism 3 to rotate; and a cutting mechanism 6, used to cut the motor housing 4. The hook-type housing fixing mechanism 3 includes a grooved shaft cylinder 31 with a tray 35 mounted on its rear side, on which a movable pull ring 32 is slidably mounted. Several hook-type positioning pull rods 33 are rotatably mounted on the movable pull ring 32. Simultaneously, a tensioning rod 34 is provided inside the grooved shaft cylinder 31, used to pull the movable pull ring 32. The sliding mechanism allows the hook positioning rod 33 to hook onto the port of the motor housing 4 and tighten it to fix it on the tray 35. In the hook-type housing fixing mechanism 3, the movable pull ring 32 can slide freely, allowing the hook positioning rod 33 installed on it to lock onto the port of the motor housing 4 of different sizes and tighten it. Since the hook positioning rod 33 only has a small contact area with the motor housing 4 at the port, it will hardly obstruct the outer wall of the motor housing 4, which facilitates the smooth progress of the cutting work. At the same time, the rotation drive mechanism 5 can drive the motor housing 4 to rotate at any angle, which facilitates the continuous operation of the cutting work. There is no need to repeatedly load and unload the motor housing 4 to change its orientation, which can significantly improve work efficiency.
[0028] The grooved shaft cylinder 31 has several sliding grooves. The movable pull ring 32 includes a sliding ring body 321 that is slidably sleeved on the grooved shaft cylinder 31. Several connecting sliders 322 that slide in the grooves are fixedly installed on the inner wall of the sliding ring body 321. A transmission ring 323 is fixedly connected to the inner end of each connecting slider 322. This structure enables a fixed connection between the transmission ring 323 and the sliding ring body 321, thus allowing the sliding ring body 321 to move synchronously when the transmission ring 323 is driven. Figure 3 As shown.
[0029] The tensioning rod 34 includes a threaded rod 341 threadedly connected to the rear end of the grooved shaft sleeve 31. Its front end passes through the transmission ring 323 and is fixedly connected to a pressure plate 342. A compression spring 343, connected to the transmission ring 323, is fixedly installed on the rear end face of the pressure plate 342. When the threaded rod 341 is turned, it drives the pressure plate 342 to move, thereby pushing the transmission ring 323 to slide, thus driving the sliding ring body 321 to slide. The compression spring 343 can apply tension to the threaded rod 341 when the turning of the threaded rod 341 stops, ensuring tight thread engagement and preventing loosening. Figure 3 As shown.
[0030] The hook positioning lever 33 includes an elastic folding lever 331, the rear end of which is rotatably connected to the sliding ring body 321 via a hinge joint 332. A fork 333 is fixedly provided at its front end, and a rotatable hook 334 is mounted in the fork 333 via a rotating shaft. The hook 334 has two locking blocks for securing the motor housing 4. This structure allows the elastic folding lever 331 to be movably connected, enabling it to adapt to motor housings 4 of different sizes by rotation. The hook 334 is used to secure the port of the motor housing 4. Furthermore, a mating piece 335 is fixedly connected to the outer end of the rotating shaft, and a return torsion spring 336 is sleeved on the rotating shaft. The two ends of the return torsion spring 336 are fixedly connected to the mating piece 335 and the fork 333, respectively. Based on this technical solution, when no external force is applied, the return torsion spring 336 can apply a return torque to restore the hook 334 to its original position, preventing the hook 334 from freely rotating and affecting operational convenience when it is secured to the port of the motor housing 4. Figure 4 As shown.
[0031] like Figure 5 As shown, the rotation drive mechanism 5 includes a transmission wheel 51 and a drive wheel 52, and also includes a stepper motor 54 mounted on the sliding bracket 2. The drive wheel 52 is mounted on the shaft end of the stepper motor 54, and the transmission wheel 51 is mounted on the end of the grooved shaft cylinder 31. The transmission wheel 51 and the drive wheel 52 are connected by a transmission belt 53. When it is necessary to drive the motor housing 4 to rotate, the stepper motor 54 drives the drive wheel 52 to rotate, and under the transmission action of the transmission belt 53, it drives the transmission wheel 51 to rotate, and finally drives the grooved shaft cylinder 31 to rotate, thereby driving the motor housing 4.
[0032] like Figure 6 As shown, the cutting mechanism 6 includes a guide rail 61, in which a sliding table 62 is slidably arranged, and an adjustable distance motor 63 is installed at the end of the guide rail 61. The output shaft of the adjustable distance motor 63 is fixedly connected to a lead screw 64, which is threadedly connected to the sliding table 62. A support frame 65 is installed on the sliding table 62, and a cutting motor 66 is installed on it. The output shaft of the cutting motor 66 is fixedly connected to a cutting blade disc 67. By driving the lead screw 64 to rotate through the adjustable distance motor 63, the sliding table 62 can be slidably adjusted to adjust the distance between the cutting motor 66 and the motor housing 4. During cutting, the cutting motor 66 drives the cutting blade disc 67 to rotate to complete the cutting process.
[0033] like Figure 5 As shown, the guide base plate 1 has several guide grooves 11, and the lower end face of the sliding bracket 2 is fixedly provided with several protrusions corresponding to the guide grooves 11. The above structure allows the sliding bracket 2 to slide in an directional manner, thereby enabling the motor housing 4 to be pushed in an directional manner during the cutting process, which facilitates the smooth progress of the cutting work.
[0034] The working principle and usage process of this utility model:
[0035] The motor housing cutting device uses a hook-claw type housing fixing mechanism 3 to position and install the motor housing 4, which facilitates efficient cutting by the cutting mechanism 6. In the hook-claw type housing fixing mechanism 3, the movable pull ring 32 can slide freely, allowing the hook positioning pull rod 33 installed on it to lock the port of the motor housing 4 of different sizes and tighten and fix it. Since the hook positioning pull rod 33 only has a small contact area with the motor housing 4 at the port, it will hardly obstruct the outer wall of the motor housing 4, which facilitates the smooth progress of the cutting work.
[0036] When the threaded rod 341 is turned, it will drive the pressure plate 342 to move, which in turn will push the transmission ring 323 to slide, thereby driving the sliding ring body 321 to slide. The sliding of the sliding ring body 321 will tighten the hook positioning rod 33, which will apply pressure to fix the motor housing 4 on the tray 35. The compression spring 343 can apply a pulling force to the threaded rod 341 when the turning of the threaded rod 341 stops, so that the thread is tightly engaged and not easy to loosen.
[0037] Meanwhile, since the hook-type housing fixing mechanism 3 is rotatably mounted on the top of the sliding bracket 2, it can drive the motor housing 4 to rotate at any angle, which facilitates continuous cutting work. There is no need to repeatedly install and remove the motor housing 4 to change its orientation, which can significantly improve work efficiency. When it is necessary to drive the motor housing 4 to rotate, the stepper motor 54 drives the drive wheel 52 to rotate, which drives the transmission wheel 51 to rotate under the transmission action of the transmission belt 53, and finally drives the grooved shaft cylinder 31 to rotate, thereby driving the motor housing 4.
[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
