Description

Technical Field

[0001] The invention relates to the technical field of end cover processing equipment, and in particular to a portable low-voltage motor end cover slotting device. Background Art

[0002] In the transformation of low-voltage motors, it is necessary to seal and protect the flat joint surfaces, stop joint surfaces, and gasket joint surfaces of various motor structural parts. Therefore, it is necessary to place O-rings at the joint surfaces, so it is necessary to open a sealing ring installation groove on the end cover.

[0003] As for the existing transformation, the motor end cover is removed before use and then sent to a nearby factory for grooving. However, in most cases, the factory is not easy to find, and the factory does not have such grooving tools. Even if the factory is found, it is not possible to give priority to processing when the factory is busy. This results in that if production is in a hurry, the motor cannot be put into use immediately. If the transformation is required at the time of purchase, the sealing groove of the motor end cover sent back will not match the size of the O-ring, resulting in the O-ring sealing groove cannot be installed and cannot be used normally, affecting normal production.

[0004] Therefore, how to provide a portable low-voltage motor end cover slotting device to solve the inconvenience of end cover slotting during existing motor modification is a technical problem that needs to be urgently solved by technical personnel in this field. Summary of the invention

DETAILED DESCRIPTION

[0067] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0068] Please follow Figures 1-16 Now, a portable low-voltage motor end cover slotting device disclosed in the present invention is described. Figure 1 , including a processing component 1, a locking component 2, a suction cup component 3, an end cover 4, a three-jaw chuck 5, a connecting component 6 and a driving component 7. The suction cup component 3 is placed on the workbench, the end cover 4 is placed on the upper surface of the suction cup component 3, the bottom of the three-jaw chuck 5 is inserted in the end cover 4, the top of the three-jaw chuck 5 is inserted with the driving component 7, the connecting component 6 is installed on the upper end of the driving component 7, the processing component 1 is transmission-connected to the connecting component 6, and the connecting component 6 is also installed with a locking component 2, the locking components 2 are arranged in pairs, and the locking components 2 are arranged on the outside of the processing component 1.

[0069] When the present invention is in use, the motor end cover to be modified is removed, and then the relatively flat side of the end cover is placed on the placement plate 35. Then, the switch 34 is twisted, and an internal hexagonal wrench is used to drive the switch 34 to rotate, so that the switch 34 generates friction with the permanent magnet 31 itself to excite the magnetism of the permanent magnet 31. The switch 34 will use a strong magnet such as a neodymium magnet to rearrange the magnetic domains inside the permanent magnet 31, so that the permanent magnet 31 generates magnetism. Under the action of the magnetism, the permanent magnet 31 attracts the end cover 4, making the end cover 4 closely adhere to the placement plate 35. After installing the end cover 4, take the three-jaw chuck 5, insert the jaw 53 into the inner side of the end cover 4 with holes and grooves, and then use the internal hexagonal wrench again, insert it into the driving head 54, and drive the driving head 54 to rotate. During the rotation of the driving head 54, the helical gear 56 will rotate accordingly, and then the helical gear 56 is engaged with the rack on the upper surface of the tapered gear ring 57 to drive the tapered gear ring 57 to rotate synchronously. Correspondingly, the position of the threaded structure 59 on the tapered gear ring 57 will also change. Using this feature, some insertion blocks are provided at the top of the jaw 53, and these insertion holes are inserted into the gaps of the threaded structure 59. When the threaded structure 59 rotates, the insertion blocks will move along the threaded structure 59. However, since the rotation of the jaw 53 is restricted, and the width of each turn of the threaded structure 59 is different, this makes the jaw 53 can only translate along with the threaded structure 59, so that the jaws 53 move apart or close together. Under the movement of the jaws 53, the outer wall of the jaws 53 will gradually approach and contact the inner wall of the end cover 4. When the jaws 53 can no longer move, the jaws 53 are clamped with the end cover 4, and at this time, the center of the end cover 4 is aligned with the center of the three-jaw chuck 5. After connecting the three-jaw chuck 5, the driving component 7 is installed on the upper end of the three-jaw chuck 5, and the connecting component 6 is sleeved on the connecting rod 71. Then, the processing component 1 is installed on the displacement rod 64, one end of the processing component 1 is abutted against the side wall of the connecting plate 61, and then the two locking components 2 are respectively sleeved on the two displacement rods 64, and one end of the locking component 2 is abutted against the processing component 1 to limit the processing component 1 and prevent the processing component 1 from sliding along the displacement rod 64 during the processing, ensuring that the processing position will not shift.After all are installed, connect the rotating motor 14 using the power supply to drive the cutter head 12 to rotate. Then, manually hold the connecting component 6 and move it downward along the connecting rod 71 to position the cutter head 12 at the machining position. First, perform a punching operation on the end cover 4. After the punching is completed, use the tapered roller bearing 73 and the ball shaft 74 to rotate the connecting rod 71, causing the connecting rod 71 to perform a circular motion. During the rotation of the connecting rod 71, it will drive the connecting component 6 and the machining component 1 to rotate synchronously. When the machining component 1 moves slowly, the rotating cutter head 12 will mill a circular sealing groove on the end cover 4. With the above structural features, the center of the driving component 7 will also be aligned with the center of the end cover 4, so that the circular sealing groove should be concentric with the circular end cover 4. Moreover, with such a neat circular sealing groove, after installing the O-ring and connecting to the motor, it can not only ensure the sealing effect but also prevent the problem of misalignment that may cause them not to be installed together. Another issue is that when driving the connecting rod 71 to rotate, it should be driven slowly to ensure that the depth of the entire circular sealing groove is consistent. The entire device has good advantages in terms of disassembly and assembly, ease of use, and device size, effectively solving the problem that users cannot independently machine the circular sealing groove of the end cover 4 by themselves.

[0070] In a specific embodiment, such as Figure 2 , the suction cup assembly 3 includes a permanent magnet 31, an adjusting bolt 32, a base 33, a switch 34, and a placement tray 35. A number of adjusting bolts 32 are installed on the surface of the base 33, a permanent magnet 31 is installed on the upper surface of the base 33, the adjusting bolts 32 are arranged on the periphery of the permanent magnet 31, the switch 34 is installed on the side surface of the permanent magnet 31, and the placement tray 35 is installed on the upper end of the permanent magnet 31. The material of the permanent magnet 31 is generally steel or iron, while the switch 34 is made of neodymium material, and the neodymium magnet is a strong magnet. Thus, when the switch 34 rubs against the permanent magnet 31, it rearranges the magnetic domains in the permanent magnet 31, causing the permanent magnet 31 to generate magnetism to attract and position the end cover 4. The purpose of setting the adjusting bolts 32 on the base 33 is that when the placement plane is uneven, the adjusting bolts 32 can be driven to extend the bottom of the adjusting bolts 32 out of the base 33 for leveling to ensure that the entire device is in a horizontal state during the machining process.

[0071] In a specific embodiment, such as Figures 3-5, the three-jaw chuck 5 includes an installation space 51, a cylinder 52, clamping jaws 53, a drive head 54, a connecting housing 55, a helical gear 56, a conical gear ring 57, a round hole 58, and a threaded structure 59. An installation space 51 is provided at the upper end of the connecting housing 55. A cylinder 52 is installed on the upper surface of the bottom plate of the connecting housing 55. A round hole 58 is provided on the top surface of the cylinder 52. The round hole 58 extends downward and penetrates the bottom plate of the connecting housing 55. A number of drive heads 54 are installed in the side wall of the connecting housing 55. The end of the drive head 54 is connected to a helical gear 56. The helical gear 56 is arranged in the installation space 51. A conical gear ring 57 is sleeved outside the cylinder 52. A rack is provided on the side surface of the conical gear ring 57. The rack meshes with the helical gear 56. The bottom of the conical gear ring 57 is a threaded structure 59. A number of clamping jaws 53 are drivingly connected to the bottom of the connecting housing 55. The usage process of the three-jaw chuck 5 has been described in detail in the specific usage method. Moreover, the structure of the three-jaw chuck 5 is basically similar to the existing three-jaw chuck 5. However, in this application, different from the existing three-jaw chuck 5, the method used is different. Most three-jaw chucks 5 are clamped outside the workpiece and are used for clamping. While in this device, on the basis of meeting the clamping requirement, the three-jaw chuck 5 is aligned with the center of the end cover 4. Such a setting will also make the position where the bottom of the processing component 1 is aligned with the end cover 4. No matter how the processing component 1 rotates along the drive component 7, the position from the indicated position to the center of the end cover 4 is the same. Thus, it is ensured that the processed sealing groove is concentric with the end cover 4. Moreover, by using the double limit of clamping with the three-jaw chuck 5 and the suction cup assembly 3, it can be ensured that the end cover 4 will not displace during processing. And precisely because the suction cup assembly 3 sucks the material, the end cover 4 can be placed at any position of the suction cup assembly 3. As long as the three-jaw chuck 5 is aligned with the center of the end cover 4 again, processing can be achieved even if the end cover 4 is not placed at the center of the suction cup assembly 3. At the same time, after installing the processing component 1, the connecting component 6, and the drive component 7 on the three-jaw chuck 5, the weight of these four components can be used to press the end cover 4, so that it will not tilt or have other problems during processing. The installation space 51 is used to install the conical gear ring 57. The cylinder 52 is for sleeving the conical gear ring 57 to make the conical gear ring 57 rotate along the cylinder 52 and prevent the conical gear ring 57 from translating during use.

[0072] In a specific embodiment, such as Figure 6, the driving component 7 includes a connecting rod 71, a dividing plate 72, a tapered roller bearing 73, a ball shaft 74, and a housing 75. The dividing plate 72 is mounted on the bottom side surface of the connecting rod 71. The ball shaft 74 is sleeved outside the connecting rod 71, and the connecting rod 71 is also sleeved with a tapered roller bearing 73. The ball shaft 74 and the tapered roller bearing 73 are respectively arranged on the upper and lower sides of the dividing plate 72, and the ball shaft 74 is arranged above the tapered roller bearing 73. The housing 75 is sleeved outside the ball shaft 74 and the tapered roller bearing 73. The bottom of the connecting rod 71 and the bottom of the tapered roller bearing 73 are inserted into the top end of the three-jaw chuck 5. When the driving component 7 is in use, by using the tapered roller bearing 73 and the ball shaft 74, the connecting rod 71 rotates, and the dividing plate 72 is provided to prevent the two bearings from affecting each other. The housing 75 is provided to fix the driving component 7 and the three-jaw chuck 5 together with bolts to prevent the driving component 7 from shifting during the processing.

[0073] In a specific embodiment, such as Figure 7 , the connecting component 6 includes a connecting plate 61, an extension plate 62, a sleeve 63, a displacement rod 64, a cushion layer 65, and a cylinder 66. The connecting plate 61 is mounted with sleeves 63 on both end surfaces. The right end of the sleeve 63 is a partition structure, and the extension plate 62 is mounted on the outer surface at the partition position. The cylinder 66 is mounted on the upper and lower surfaces of the connecting plate 61. An installation hole is opened in the cylinder 66, and the installation hole penetrates the connecting plate 61. The cushion layer 65 is mounted on the wall of the installation hole. The displacement rods 64 are arranged in pairs and are mounted in the two sleeves 63. The processing component 1 and the locking component 2 are mounted on the displacement rods 64. The connecting plate 61 is used to connect the sleeve 63 and the cylinder 66. The cylinder 66 is provided so that the entire connecting component 6 can be connected to the connecting rod 71 and the connecting component 6 can move up and down along the connecting rod 71. The cushion layer 65 is provided to increase the friction at the connection between the connecting component 6 and the connecting rod 71, so that after the position of the connecting component 6 is determined, the connecting component 6 will not move down along the connecting rod 71 during the processing. The extension plate 62 and the partition structure are provided to make the two separated sleeves 63 approach each other. After approaching, the displacement rod 64 can be clamped to prevent the displacement rod 64 from moving during the processing.

[0074] In a specific embodiment, such as Figure 8 , the processing component 1 includes a connecting plate 11, a cutter head 12, a connecting cylinder 13, and a rotary motor 14. The connecting cylinders 13 are mounted on both side walls of the connecting plate 11. The connecting cylinders 13 are sleeved on the displacement rods 64. The rotary motor 14 is mounted on the connecting plate 11, and the cutter head 12 is mounted at the bottom output end of the rotary motor 14. The processing component 1 is a commonly used milling cutter, and with the connecting plate 11 and the connecting cylinder 13, the milling cutter is connected to this device to realize the portable processing of the end cover 4. The connecting cylinder 13 is used to connect the processing component 1 and the displacement rod 64.

[0075] In a specific embodiment, such as Figure 9 , the locking assembly 2 includes an outer sleeve 21, an inner conical sleeve 22, an inner sleeve 23, a limiting ball 24 and a pull cap 25. The inner conical sleeve 22 is installed inside the outer sleeve 21, the inner sleeve 23 is installed inside the inner conical sleeve 22, a number of round holes are formed on the side wall of the inner sleeve 23, the limiting ball 24 is installed in the round holes, the pull cap 25 is installed at one end of the inner conical sleeve 22, and the inner conical sleeve 22 is longer than the outer sleeve 21. For the locking assembly 2, its installation purpose is to limit the position of the processing assembly 1, so as to ensure that the processing position will not change. After the locking assembly 2 is sleeved on the displacement rod 64 and one end of the locking assembly 2 abuts against the processing assembly 1, the pull cap 25 is pulled, so that the inner conical sleeve 22 generates displacement, and by using the conical structure of its inner surface, the limiting ball 24 is pushed outwards from the round hole. In this way, the limiting ball 24 slowly approaches and abuts against the displacement rod 64. When the limiting ball 24 is tightly squeezed with the displacement rod 64, the limiting of the entire locking assembly 2 can be completed, and the limiting of the processing assembly 1 is also realized.

[0076] In a specific embodiment, such as Figures 10-11, the connecting component 6 further includes a rectangular hole 67, a rectangular limiting block 68, a limiting ring 69, a clamping rod 610, a clamping spring 611 and a displacement groove 612. The displacement groove 612 is formed in the sleeve 63. A clamping spring 611 is installed in the displacement groove 612. The end of the clamping spring 611 is connected to a clamping rod 610. The clamping rod 610 is drivingly connected in the displacement groove 612. A limiting hole is formed in the left end surface of the sleeve 63, and a rectangular hole 67 is formed beside the limiting hole. The limiting hole is communicated with the rectangular hole 67 and the displacement groove 612. The limiting ring 69 is installed on the outer surface of one end of the clamping rod 610, and a rectangular limiting block 68 is connected to the outer end of the limiting ring 69. For the structure shown in the above embodiment, there is a problem. That is, since the lengths of the connecting plate 61 and the sleeve 63 are fixed, but one end of the processing component 1 still needs to abut against the connecting plate 61 and the sleeve 63, this results in the installation position of the processing component 1 being fixed and unable to punch other positions of the end cover 4. If other positions need to be processed, gaskets need to be added between the processing component 1 and the sleeve 63. However, the gaskets need to be processed, and the self-made gaskets are inevitably subject to errors, resulting in different lengths, and ultimately the installation position of the processing component 1 cannot be guaranteed. Therefore, the present device provides another idea, which is to add a displacement groove 612 to the sleeve 63. The displacement groove 612 is provided between the inner and outer surfaces of the sleeve 63, which does not affect the inner surface of the sleeve 63 being in contact with the displacement rod 64. The clamping rod 610 is displaced in the displacement groove 612, and a clamping spring 611 is arranged between the displacement groove 612 and the clamping rod 610. In the normal state, a part of the clamping rod 610 extends outside the sleeve 63. When the processing component 1 is installed, the movement of the processing component 1 will drive the clamping rod 610 to displace towards the inside of the sleeve 63, and the clamping spring 611 will be compressed. After the position is determined and the processing component 1 is fixed at one end by the locking component 2, at this time, the clamping spring 611 is in a compressed state. The elastic force of the clamping spring 611 is applied to the clamping rod 610, driving the clamping rod 610 to make one end of the limiting ring 69 and the rectangular limiting block 68 abut against the processing component 1, so as to realize the limitation of the processing component 1. By using such a clamping method, the processing component 1 can be fixed at any position of the displacement rod 64 to realize the processing of different positions of the end cover 4. The setting of the rectangular hole 67 and the limiting hole is to limit the entering depth of the clamping rod 610, and the rectangular limiting block 68 and the limiting ring 69 can also increase the contact area between the clamping rod 610 and the side wall of the processing component 1.

[0077] In a specific embodiment, such as Figures 12-15, the suction cup assembly 3 further includes a displacement hole 36, a clamping member 37, and a jack 38. The jack 38 is opened on the upper surface of the placement plate 35. Four displacement holes 36 are provided on the periphery of the jack 38, and a clamping member 37 is drivingly connected in the displacement hole 36; the clamping member 37 includes a top block 371, a sleeve rod 372, a driving rod 373, a clamping spring 374, a mounting plate 375, a clamping block 376, a movable rod 377, a driving spring 378, and a clamping block 379. One end of the driving rod 373 is drivingly connected in the placement plate 35 and a clamping block 379 is provided at the end. The other end of the driving rod 373 is provided with a mounting plate 375. The clamping spring 374 is sleeved outside the driving rod 373. The clamping spring 374 is installed between the mounting plate 375 and the end of the displacement hole 36. The sleeve rod 372 is installed on the mounting plate 375. A top block 371 is installed at one end of the sleeve rod 372. The outer surface of the top block 371 is set as a convex structure. A collar is provided on the outer surface of the other end of the sleeve rod 372 and a retaining ring is provided inside. One end of the movable rod 377 is connected with a clamping block 376. An arc structure is provided on one end surface of the clamping block 376. A driving spring 378 is provided at the other end of the movable rod 377 and a limiting ring is installed on the outer surface. The other end of the driving spring 378 is connected to the inner wall of the sleeve rod 372. For this device, to solve the problem that the end cover 4 cannot be placed at the center position of the placement plate 35, another solution is to open a jack 38 on the placement plate 35, and provide an extension rod 76 at the bottom of the connecting rod 71. Then, a movable clamping member 37 is provided in the displacement hole 36 on the side of the jack 38. After the three-jaw chuck 5 is installed, the extension rod 76 is passed through the three-jaw chuck 5 and placed in the jack 38. By using the clamping member 37, while clamping the extension rod 76, the end cover 4 is centered and limited again to ensure the correct position of the end cover 4 during processing. During the use of the clamping member 37, there are two methods. One is to first connect the end cover 4 to the suction cup assembly 3, and the other is to first connect the end cover 4 to the three-jaw chuck 5. For the first installation method, before starting the suction cup assembly 3, first place the end cover 4 on the placement plate 35. Here, a specific description is made for the case where the diameter of the middle hole of the end cover 4 is different. First, for a small diameter, at this time, it is necessary to simultaneously pull the four clamping members 37 to displace and make them approach each other. Then, the four clamping members 37 can pass through the middle hole. When the clamping member 37 is displaced, the clamping spring 374 undergoes tensile deformation and generates elastic force. When the clamping member 37 is released, under the action of the spring, the clamping members 37 move away from each other. During the movement, the top block 371 gradually approaches and abuts against the inner wall of the middle hole. At this time, according to the different diameters of the middle hole, in some cases, after the top block 371 abuts, the clamping member 37 has not been reset. At this time, if the clamping member 37 is moved again, the sleeve rod 372 will move along the mounting plate 375. At this time, it is necessary to insert an extension rod 76 with a smaller diameter because when the extension rod 76 is inserted, the side of the extension rod 76 will drive the movable rod 377 to move,In the case where the sleeve rod 372 cannot move, only the movable rod 377 can be moved into the sleeve rod 372, and the driving spring 378 is compressed. However, the compression of the driving spring 378 is limited. If the diameter of the extension rod 76 is too large at this time, it will cause the displacement of the movable rod 377, making the compression of the driving spring 378 exceed the elastic limit. But if the diameter of the extension rod 76 is appropriate, after the movable rod 377 moves, a certain amount of compression is generated in the driving spring 378. In this case, the driving spring 378 remains compressed, and the elastic force is respectively applied to the movable rod 377 and the sleeve rod 372, so that the clamping block 376 and the top block 371 better abut against the extension rod 76 and the middle hole. By using multiple such identical structures, the positions of the connecting rod 71 and the end cover 4 can be finely adjusted again, so that the central positions of the end cover 4 and the connecting rod 71 are kept consistent, thereby achieving better processing. Moreover, the multiple clamping blocks 376 clamp the extension rod 76. Since the clamping members 37 are arranged at the same position and are all at the center circle position, after such fine adjustment, the end cover 4 and the connecting rod 71 can be placed at the center of the placement tray 35, and then the suction cup assembly 3 can be started to suck the material. In some cases, after abutting, the clamping member 37 is basically reset. At this time, an extension rod 76 with a slightly larger diameter can be used. The purpose is to be able to drive the displacement of the movable rod 377. Since the top block 371 already abuts against the middle hole, making the extension rod 76 wider allows the movable rod 377 to displace more, compressing the driving spring 378, so that the elastic force of the driving spring 378 can be applied to the movable rod 377 and the sleeve rod 372, thereby achieving the above-mentioned clamping effect. For those with a larger middle hole, when placing the end cover 4, it is not necessary to move the clamping member 37. However, at this time, an extension rod 76 with a diameter slightly smaller than or equal to the diameter of the insertion hole 38 is required. When the extension rod 76 is installed, when the extension rod 76 is inserted, it drives the clamping members 37 to move away from each other. During the moving-away process, the clamping spring 374 is compressed, and the pressure is applied to the extension rod 76 to generate a primary limit. At the same time, the extension rod 76 also causes the movable rod 377 to drive the sleeve rod 372 to displace on the mounting plate 375. During the displacement process, the top block 371 gradually approaches and abuts against the middle hole wall. After the sleeve rod 372 cannot move, gradually the movable rod 377 will continue to move into the sleeve rod 372, making the driving spring 378 compressed. The compressed elastic force is applied to the end cover 4 and the extension rod 76 to limit and finely adjust them. Although the three-jaw chuck 5 has been centered once, the secondary fine adjustment does not conflict. For the second usage case, after connecting the end cover 4 and the three-jaw chuck 5 together, during installation, it should be noted that it is best to pinch the sleeve rod 372 and the movable rod 377 together when the clamping member 37 enters the middle hole, and then it will actively loosen under the action of the elastic force after installation to limit the end cover 4 and the extension rod 76. By using the double-activity clamping mechanism of the sleeve rod 372, the movable rod 377 and the driving spring 378, the limiting and fine-adjusting effects can be better achieved.

[0078] In a specific embodiment, such as Figure 16 , an extension rod 76 is installed at the bottom of the connecting rod 71.
