Description

Technical Field

[0001] This invention relates to the field of motor housing turning technology, and in particular to a CNC machine tool for machining motor housings. Background Technology

[0002] With the rapid development of the automotive industry, automotive motors, as core components, have seen continuous improvement in performance and quality standards. As a key component, the motor housing not only protects internal parts but also significantly affects motor heat dissipation, electromagnetic shielding, and overall stability. Therefore, the machining accuracy and quality of the housing directly affect the performance and operational reliability of the automotive motor. In turning, the workpiece rotates, and the cutting tool moves in a straight line or curve within a plane. This is usually done on a lathe and can machine inner and outer cylindrical surfaces, end faces, conical surfaces, and shaped surfaces. When machining inner and outer cylindrical surfaces, the cutting tool moves in a direction parallel to the workpiece's axis of rotation.

[0003] When cutting the end face of the motor housing, most existing motors are clamped on the outer wall or by molds, which has low adaptability and is not easy to process motor housings of various sizes. In addition, the motor housing is relatively heavy, and the installation and disassembly on the lathe are time-consuming and labor-intensive due to the limited opening space of the lathe. Therefore, improvements are needed. Summary of the Invention

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Example, refer to Figures 1-10This embodiment of the invention provides a CNC machine tool for machining motor housings. It enables fixation from the inner wall of the motor housing, is adaptable to machining various motor housings, and offers convenient installation and disassembly. The tool includes a lathe assembly 100, comprising a housing assembly 200 fixed to the inner side of the lathe assembly 100, four positioning components 300 and a fixing component 400 sliding on the outer wall of the housing assembly 200, a driven component 500 sliding at the center of the housing assembly 200, a driving component 600 sliding within the driven component 500, a pressing component 700 fixed to the end face of the fixing component 400, and a delay component 800 movably connected to the end of the driven component 500. The delay component 800 is connected to the driving component 600 and fixed to the lathe assembly. When machining the motor housing is required, the trigger component 900 inside the lathe assembly 100, by fitting the motor housing onto the outer wall of the housing assembly 200 and supporting the motor housing with the positioning component 300, moves the trigger component 900 toward the delay component 800 via the propulsion device on the lathe assembly 100. The trigger component 900 then pushes the delay component 800 to move. The delay component 800 first triggers the positioning component 300 to expand outward, which centers the motor housing outside the positioning component 300. Then, the delay component 800 triggers the fixing component 400 to fix the motor housing. At this time, the rotary drive on the lathe assembly 100 is activated to drive the housing assembly 200 and subsequent structures to rotate the motor housing, allowing the end of the motor housing to be machined.

[0033] Specifically, such as Figure 2 In the lathe assembly 100, there are a lathe body 101, a rotary disk 102 rotating on the inner left side of the lathe body 101, the rotary disk 102 being connected to a rotary drive inside the lathe body 101, a feed disk 103 sliding on the inner bottom of the lathe body 101, the feed disk 103 being connected to a feed drive inside the lathe body 101, and a cutting tool 104 fixed on the top of the feed disk 103. In use, the rotary disk 102 can drive the structure at the end face to rotate, and the feed disk 103 can drive the cutting tool 104 to turn the motor housing fixed on the end face of the rotary disk 102.

[0034] Further, such as Figure 5 In the case, the housing assembly 200 includes a housing 201 fixed to the end face of the lathe assembly 100. The housing 201 is fixed to the end face of the lathe body 101 in the lathe assembly 100, and the inner wall of the housing 201 is provided with a cross groove 202.

[0035] Further, such as Figure 6 , 8In the positioning component 300, there is an expansion plate 301 that slides at the four openings of the cross groove 202. The end face of the expansion plate 301 has a groove 302, which is suitable for sliding use by the driven component 500 and the driving component 600. The expansion plate 301 has a first inclined groove 303 on both sides of the groove 302, and a roller 304 rotates on the outside of the expansion plate 301. The driven component 500 includes a hollow tube 501 that slides at the center of the outer shell 201. The end of the hollow tube 501 has a threaded groove 502. The hollow tube 501 has a slot 503 at the fixing component 400. The hollow tube 501 has a slot 503 at the extrusion plate 401 in the fixing component 400. The driving plate 504 is fixed to the hollow tube 501 on the side of the slot 503. The first slider 505 is located at the end face of the active plate 504 at the positioning component 300. The active plate 504 is located at the first inclined groove 303 in the positioning component 300. In use, the motor housing is sleeved on the positioning component 300 on the outer wall of the housing component 200. By squeezing the hollow tube 501, the active plate 504 and the first slider 505 can be moved. Since the first slider 505 is located in the first inclined groove 303, the first slider 505 can drive the expansion plate 301 and the roller 304 to squeeze the inner wall of the motor housing. Thus, the four expansion plates 301 and the roller 304 can position the motor housing. During positioning, the motor housing is supported by the roller 304, so the wear on the inner wall of the motor housing can be reduced during positioning.

[0036] Further, such as Figure 6 , 7 In the middle, the fixed component 400 includes an extrusion plate 401 that slides in the cross groove 202 at the expansion plate 301. The extrusion plate 401 has second inclined grooves 402 on both sides, the second inclined groove 402 being longer than the first inclined groove 303. A triangular strip 403 is fixed to the outside of the extrusion plate 401, the end face of the triangular strip 403 having an inclination. A friction pad 404 is fixed to the end face of the triangular strip 403. The active component 600 includes a central rod 601 that slides inside the hollow tube 501, a driven plate 602 fixed to the outer wall of the central rod 601 at the slot 503, and a first slider 505 fixed to the end face of the driven plate 602. On the opposite end, the second slider 603 slides within the second inclined groove 402. During use, the driven plate 602 and the second slider 603 are moved by the squeezing center rod 601. Since the second slider 603 is located within the second inclined groove 402, it can drive the squeezing plate 401, the triangular strip 403, and the friction pad 404 to expand outward. As a result, the friction pad 404 can be squeezed against the inner wall of the motor housing to fix the motor housing. Because the end face of the triangular strip 403 has an inclination, it adapts to the inclination arc of the inner wall of the motor housing, so the friction pad 404 can better fit the inner wall of the motor housing.

[0037] Further, such as Figure 7In the process, the extrusion assembly 700 includes a fixing plate 701 fixed to the end face of the fixing assembly 400. The outer end of the fixing plate 701 is provided with an arc-shaped groove 702 and a brake pad 703 fixed at the arc-shaped groove 702. When the extrusion plate 401 moves, it can drive the fixing plate 701 and the brake pad 703 to move to the outer wall of the roller 304 and form an extrusion force on the roller 304, thereby preventing the roller 304 from rotating and strengthening the fixing effect on the inner wall of the motor housing.

[0038] Further, such as Figure 9 In the process, the delay component 800 includes a nut 801 slidably connected to the end of the driven component 500. The nut 801 is threadedly connected to the threaded groove 502 in the driven component 500. A housing 802 rotates around the end of the nut 801. A pressing block 803 slides around the end of the housing 802. The pressing block 803 is connected to the driving component 600 and is connected to the central rod 601 in the driving component 600. The end face of the pressing block 803 has a tapered groove 804. A first spring 805 is fixed between the housing 802 and the pressing block 803. During use, the pressing block 803 moves towards the housing component 200, thereby driving the spring 805, the housing 802, the nut 801, and the hollow tube 501 to move, thus... First, the driven component 500 is triggered to drive the positioning component 300 to position the motor housing. After positioning is completed, the roller 304 and expansion plate 301 in the positioning component 300 cannot move. As a result, the first slider 505 in the driven component 500 is also unable to move because it is in the first inclined groove 303. Consequently, the slider 505, the driving plate 504, and the hollow tube 501 will also be unable to move. At this time, the extrusion block 803 continues to move, which can compress the first spring 805. At the same time, the extrusion block 803 will drive the center rod 601, the driven plate 602, and the second slider 603 to trigger the fixing component 400 to fix the inner wall of the motor housing. This allows for quick positioning and fixing of motor housings of different models and sizes during processing.

[0039] Further, such as Figure 10In the process, the triggering assembly 900 includes a fixed housing 901 fixed to the top center of the lathe assembly 100. The fixed housing 901 is fixed to the top center of the feed plate 103 in the lathe assembly 100. A reinforcing rod 902 slides on the end face of the fixed housing 901. A tapered block 903 is fixed to the end face of the reinforcing rod 902. The tapered block 903 and the tapered groove 804 are adapted to each other. A second spring 904 is fixed between the fixed housing 901 and the reinforcing rod 902. The elastic force of the second spring 904 is greater than that of the first spring 805. In use, the feed plate 103 drives the fixed housing 901, the second spring 904, the reinforcing rod 902, and the tapered block 904. Block 903 moves toward extrusion block 803. At this time, conical block 903 can be easily inserted into conical groove 804 for connection, which can strengthen the support strength of extrusion block 803 and its subsequent structure, and make it more stable when rotating disk 102 and subsequent structure drive motor housing to rotate. Since the elastic force of spring 904 is greater than that of spring 805, trigger component 900 can drive delay component 800 to trigger subsequent structure to position and fix motor housing. Then, the elastic space of spring 904 can make push disk 103 drive cutting tool 104 to move toward end face of motor housing, and turn end face of motor housing.

[0040] In use, the motor housing is fitted onto the positioning component 300 on the outer wall of the housing assembly 200. The pusher disc 103 drives the fixed housing 901, the second spring 904, the reinforcing rod 902, and the conical block 903 towards the extrusion block 803. At this time, the conical block 903 can easily be inserted into the conical groove 804 for connection, strengthening the support of the extrusion block 803 and its subsequent structures. This provides greater stability when the rotating disc 102 and subsequent structures rotate the motor housing. Because the elastic force of the second spring 904 is greater than that of the first spring 805, the triggering component 900 can drive the extrusion block 803 towards the housing assembly 200. Thus, the extrusion block... 803 can drive the spring 805, equipment housing 802, nut 801, and hollow tube 501 to move. By pressing the hollow tube 501, it can drive the drive plate 504 and the first slider 505 to move. Since the first slider 505 is located in the first inclined groove 303, it can drive the expansion plate 301 and roller 304 to press the inner wall of the motor housing. Thus, the four expansion plates 301 and roller 304 can position the motor housing. During positioning, the motor housing is supported by the roller 304, which reduces wear on the inner wall of the motor housing. After positioning is completed, the roller 304 and expansion plates 301 in the positioning assembly 300... Since the first slider 505 in the driven assembly 500 is unable to move, it is also unable to move because it is located in the first inclined groove 303. Consequently, slider 505, driving plate 504, and hollow tube 501 will also be unable to move. At this time, the pressing block 803 continues to move, which can compress the first spring 805. At the same time, the pressing block 803 will drive the center rod 601, driven plate 602, and second slider 603 to move. The second slider 603 is located in the second inclined groove 402, so it can drive the pressing plate 401, triangular strip 403, and friction pad 404 to expand outward. Thus, the friction pad 404 can press against the motor. The inner wall of the outer casing is used to fix the motor housing. Because the end face of the triangular strip 403 has an inclination, it is adapted to the inclination arc of the inner wall of the motor housing. As a result, the friction pad 404 can better fit the inner wall of the motor housing. This allows for quick positioning and fixing of motor housings of different models and sizes. Then, the elastic space of the second spring 904 allows the push plate 103 to drive the cutting tool 104 to move towards the end face of the motor housing, which can be turned. When the push plate 103 drives the trigger component 900 to reset, the weight of the motor housing will squeeze the positioning component 300 and the fixing component 400 to reset. Thus, the motor housing can be processed continuously.

[0041] In summary, the delay component 800 can first trigger the driven component 500 and the positioning component 300 to center and position the motor housing. Then, the active component 600 and the fixing component 400 can fix the motor housing. After that, the trigger component 900 can trigger the delay component 800 and drive the cutting tool 104 to turn the end of the motor housing, and strengthen the support effect of the motor housing.
