Detailed implementation manners

[0029] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings of the specification.

[0030] Example, refer to Figures 1 to 10, which is an embodiment of the present invention. This embodiment provides a numerically controlled machine tool for machining the motor housing, which can fix the motor housing from the inner wall, can be adapted to the machining of various motor housings, and has a convenient effect during installation and disassembly. It includes a lathe assembly 100, which includes a housing assembly 200 fixed inside the lathe assembly 100, four positioning assemblies 300 and a fixing assembly 400 that slide on the outer wall of the housing assembly 200, a driven assembly 500 that slides in the center of the housing assembly 200, a driving assembly 600 that slides inside the driven assembly 500, an extrusion assembly 700 fixed to the end face of the fixing assembly 400, a delay assembly 800 that is pivotally connected to the end of the driven assembly 500, the delay assembly 800 is connected to the driving assembly 600, and a triggering assembly 900 fixed inside the lathe assembly 100. When machining the motor housing is required, the motor housing is sleeved on the outer wall of the housing assembly 200, and the motor housing is supported by the positioning assemblies 300. Then, the triggering assembly 900 is driven by the propulsion device on the lathe assembly 100 to move towards the delay assembly 800. Then, the triggering assembly 900 can push the delay assembly 800 to move. The delay assembly 800 can first trigger the positioning assemblies 300 to expand outwards, enabling the motor housing outside the positioning assemblies 300 to be centered. Then, the delay assembly 800 can trigger the fixing assembly 400 to fix the motor housing. At this time, the rotation drive on the lathe assembly 100 is started to drive the housing assembly 200 and subsequent structures to drive the motor housing to rotate. At this time, the end of the motor housing can be turned.

[0031] Specifically, as Figure 2 shown, the lathe assembly 100 includes a lathe main body 101, a rotating disk 102 that rotates on the left inner wall of the lathe main body 101. The rotating disk 102 is connected to the rotation drive inside the lathe main body 101, a propulsion disk 103 that slides on the bottom inner wall of the lathe main body 101. The propulsion disk 103 is connected to the propulsion drive inside the lathe main body 101, and a turning tool 104 fixed to the top of the propulsion disk 103. During use, the rotating disk 102 can drive the structures at the end face to rotate, and the propulsion disk 103 can drive the turning tool 104 to turn the motor housing fixed to the end face of the rotating disk 102.

[0032] Furthermore, as Figure 5 shown, the housing assembly 200 includes a housing 201 fixed to the end face of the lathe main body 101, and a cross groove 202 is provided on the inner wall of the housing 201.

[0033] Furthermore, as Figure 6 shown 8In this case, the positioning component 300 includes an expansion plate 301 that slides at the four open ends of the cross groove 202. The end face of the expansion plate 301 is provided with a groove 302, and the groove 302 is suitable for the sliding use of the driven component 500 and the active component 600. On both sides of the groove 302 of the expansion plate 301, there are first inclined grooves 303, and a roller 304 that rotates outside the expansion plate 301; the driven component 500 includes a hollow tube 501 that slides at the center of the housing 201. The end of the hollow tube 501 is provided with a threaded groove 502. The hollow tube 501 is provided with a slot 503 at the position of the fixing component 400. The hollow tube 501 is provided with a slot 503 at the pressing plate 401 in the fixing component 400. An active plate 504 is fixed on the hollow tube 501 on the side of the slot 503, and a first slider 505 is fixed on the end face of the active plate 504 at the position of the positioning component 300. The active plate 504 is the first slider 505 at the first inclined groove 303 in the positioning component 300. When in use, the motor housing is sleeved on the positioning component 300 on the outer wall of the housing assembly 200. By squeezing the hollow tube 501, the active plate 504 and the first slider 505 can be driven to move. 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, and when positioning, the motor housing is supported at the position of the roller 304. Therefore, the wear on the inner wall of the motor housing can be reduced during positioning.

[0034] Further, as Figure 6 、 7 In this case, the fixing component 400 includes a pressing plate 401 that slides at the position of the expansion plate 301 in the cross groove 202. On both sides of the pressing plate 401, there are second inclined grooves 402. The length of the second inclined grooves 402 is longer than that of the first inclined grooves 303. A triangular strip 403 is fixed on the outside of the pressing plate 401. The end face of the triangular strip 403 has an inclination. A friction pad 404 is fixed on the end face of the triangular strip 403; the active component 600 includes a central rod 601 that slides in the hollow tube 501. A driven plate 602 is fixed on the outer wall of the central rod 601 at the position of the slot 503. A second slider 603 is fixed on the end face of the driven plate 602 corresponding to the opposite end of the first slider 505. The second slider 603 slides in the second inclined groove 402. When in use, by squeezing the central rod 601, the driven plate 602 and the second slider 603 can be driven to move. Since the second slider 603 is located in the second inclined groove 402, the second slider 603 can drive the pressing plate 401, the triangular strip 403, and the friction pad 404 to expand outwards. Thus, the friction pad 404 can be squeezed against the inner wall of the motor housing to fix the motor housing. Since the end face of the triangular strip 403 has an inclination, it adapts to the inclined arc of the inner wall of the motor housing. Thus, the friction pad 404 can better fit the inner wall of the motor housing.

[0035] Further, as Figure 7In it, the extrusion assembly 700 includes a fixing plate 701 fixed to the end face of the fixing assembly 400. An arc-shaped groove 702 is provided at the outer end of the fixing plate 701, and a brake pad 703 is 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, so that the roller 304 will not rotate, strengthening the fixing effect on the inner wall of the motor housing.

[0036] Furthermore, as Figure 9 In it, the delay assembly 800 includes a nut 801 hinged to the end of the driven assembly 500. The nut 801 is threadedly connected to the threaded groove 502 in the driven assembly 500. A device housing 802 rotates at the end of the nut 801, and an extrusion block 803 slides at the end of the device housing 802. The extrusion block 803 is connected to the driving assembly 600. The extrusion block 803 is connected to the central rod 601 in the driving assembly 600. A tapered groove 804 is provided at the end face of the extrusion block 803, and a first spring 805 is fixed between the device housing 802 and the extrusion block 803. During use, the extrusion block 803 moves towards the housing assembly 200. Thus, the extrusion block 803 can drive the spring 805, the device housing 802, the nut 801, and the hollow tube 501 to move. Furthermore, it can first trigger the driven assembly 500 to drive the positioning assembly 300 to position the motor housing. When the positioning is completed, the roller 304 and the expansion plate 301 in the positioning assembly 300 cannot move. Thus, since the first slider 505 in the driven assembly 500 is in the first inclined groove 303, the first slider 505 cannot move either. Furthermore, the slider 505, the driving plate 504, and the hollow tube 501 will not be able to move. At this time, when the extrusion block 803 continues to move, it can squeeze the first spring 805 to compress it. At the same time, the extrusion block 803 will drive the central rod 601, the driven plate 602, and the second slider 603 to trigger the fixing assembly 400 to fix the inner wall of the motor housing. Thus, during processing, the motor housing of different model sizes can be quickly positioned and fixed.

[0037] Furthermore, as Figure 10Among them, the trigger assembly 900 includes a fixed housing 901 fixed to the center of the top of the propulsion disk 103, a reinforcing rod 902 sliding on the end face of the fixed housing 901, a conical block 903 fixed to the end face of the reinforcing rod 902. The conical block 903 is adapted to the conical groove 804. 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. During use, the propulsion disk 103 drives the fixed housing 901, the second spring 904, the reinforcing rod 902, and the conical block 903 to move towards the extrusion block 803. At this time, the conical block 903 can be easily inserted into the conical groove 804 for connection, which can enhance the support strength of the extrusion block 803 and its subsequent structures, and can be more stable when the rotating disk 102 and its subsequent structures drive the motor housing to rotate. Because the elastic force of the second spring 904 is greater than that of the first spring 805, the trigger assembly 900 can drive the delay assembly 800 to trigger the subsequent structures to position and fix the motor housing. Then, the elastic force space of the second spring 904 enables the propulsion disk 103 to drive the turning tool 104 to move towards the end face of the motor housing, and can turn the end face of the motor housing.

[0038] In use, the motor housing is sleeved on the positioning component 300 on the outer wall of the housing component 200. The pushing disk 103 drives the fixed housing 901, the second spring 904, the reinforcing rod 902, and the conical block 903 to move towards the extrusion block 803. At this time, the conical block 903 can be easily inserted into the conical groove 804 for connection, which can enhance the support strength of the extrusion block 803 and its subsequent structures, and can make the rotation of the motor housing driven by the rotating disk 102 and its subsequent structures more stable. Since 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 to move towards the housing component 200. Thus, the extrusion block 803 can drive the spring 805, the equipment housing 802, the nut 801, and the hollow tube 501 to move. By extruding the hollow tube 501, the driving plate 504 and the first slider 505 can be driven to move. 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 extrude the inner wall of the motor housing. Thus, the four expansion plates 301 and the roller 304 can position the motor housing, and during positioning, the motor housing is supported at the roller 304, so the wear on the inner wall of the motor housing can be reduced during positioning. When the positioning is completed, the roller 304 and the expansion plate 301 in the positioning component 300 cannot move. Thus, since the first slider 505 in the driven component 500 is located in the first inclined groove 303, the first slider 505 cannot move either. Furthermore, the slider 505, the driving plate 504, and the hollow tube 501 will not be able to move. At this time, the extrusion block 803 continues to move, which can squeeze the first spring 805 for compression. At the same time, the extrusion block 803 will drive the central rod 601, the driven plate 602, and the second slider 603 to move. Since the second slider 603 is located in the second inclined groove 402, the second slider 603 can drive the extrusion plate 401, the triangular strip 403, and the friction pad 404 to expand outwards. Thus, the friction pad 404 can be squeezed against the inner wall of the motor housing to fix the motor housing. Since the end face of the triangular strip 403 has an inclination, it can adapt to the inclined arc of the inner wall of the motor housing. Thus, the friction pad 404 can better fit the inner wall of the motor housing, and thus the motor housing of different model sizes can be quickly positioned and fixed. Then, the elastic force space of the second spring 904 can make the pushing disk 103 drive the turning tool 104 to move towards the end face of the motor housing, and the end face of the motor housing can be turned. And when the pushing disk 103 drives the triggering 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 coherently.

[0039] In summary, through the delay component 800, the driven component 500 and the positioning component 300 can be triggered first to center the motor housing, and then through the driving component 600 and the fixing component 400, the motor housing can be fixed. Then, the triggering component 900 can trigger the delay component 800 and drive the turning tool 104 to turn the end of the motor housing, and strengthen the supporting effect on the motor housing.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
