Description
Technical Field
[0001] This utility model relates to the technical field of end cap processing equipment, specifically to a portable low-voltage motor end cap grooving device. Background Technology
[0002] In the retrofitting of low-voltage motors, it is necessary to seal and protect the planar joint surfaces, locating joint surfaces, and gasket joint surfaces of various structural components of the motor. Therefore, O-rings need to be placed at the joint surfaces, which requires opening a sealing ring installation groove on the end cover.
[0003] In existing modifications, the motor end cover is removed before use and sent to a nearby factory for grooving. However, factories are often hard to find, and manufacturers often lack the necessary grooving tools. Even when a factory is found, it may not be able to prioritize processing during busy periods. This means that if production is urgent, the motor cannot be put into use immediately. If modifications are requested at the time of purchase, the returned motor end cover sealing groove may not match the size of the O-ring, making it impossible to install the O-ring and rendering it unusable, thus affecting normal production.
[0004] Therefore, how to provide a portable low-voltage motor end cover slotting device to solve the problem of inconvenient end cover slotting during existing motor modification is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation
[0067] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0068] Please refer to Figures 1-16 The present invention discloses a portable low-voltage motor end cover grooving device, such as... Figure 1 The assembly includes a processing component 1, a locking component 2, a suction cup component 3, an end cap 4, a three-jaw chuck 5, a connecting component 6, and a driving component 7. The suction cup component 3 is placed on the worktable, and the end cap 4 is placed on the upper surface of the suction cup component 3. The bottom of the three-jaw chuck 5 is inserted into the end cap 4, and the driving component 7 is inserted into the top of the three-jaw chuck 5. The connecting component 6 is installed on the upper end of the driving component 7. The processing component 1 is drivenly connected to the connecting component 6. The connecting component 6 is also equipped with a locking component 2. The locking components 2 are arranged in pairs and are located on the outside of the processing component 1.
[0069] In use, the motor end cap that needs to be modified is removed, and the flat side of the end cap is placed on the tray 35. Then, the switch 34 is turned using an Allen wrench to drive the switch 34 to rotate, so that the switch 34 and the permanent magnet 31 generate friction to stimulate the magnetism of the permanent magnet 31. The switch 34 uses a neodymium magnet, a strong magnet, to rearrange the magnetic domains inside the permanent magnet 31, so that the permanent magnet 31 generates magnetism. Under the action of magnetism, the permanent magnet 31 attracts the end cap 4, so that the end cap 4 is tightly attached to the tray 35. After installing end cap 4, remove the three-jaw chuck 5 and insert the jaws 53 into the slotted side of end cap 4. Then, use an Allen wrench to insert it into the drive head 54 and drive the drive head 54 to rotate. During the rotation of the drive head 54, the helical gear 56 will rotate accordingly. Then, the helical gear 56 will mesh with the rack on the upper surface of the conical gear ring 57, driving the conical gear ring 57 to rotate synchronously. Correspondingly, the position of the thread structure 59 on the conical gear ring 57 will also change. Taking advantage of this feature, some inserts are provided on the top of the jaws 53. These inserts are inserted into the thread structure. In the gap of structure 59, when the thread structure 59 rotates, the insert will move along the thread structure 59. However, due to the restriction on the rotation of the jaw 53, and the fact that the width of each turn of the thread structure 59 is different, the jaw 53 can only move with the thread structure 59, causing the jaws 53 to separate or come together. Under the movement of the jaws 53, the outer wall of the jaws 53 will gradually approach the inner wall of the end cover 4 and contact the inner wall. When the jaws 53 can no longer move, the jaws 53 are locked with the end cover 4. 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, install the drive assembly 7 on the upper end of the three-jaw chuck 5, and put the connecting assembly 6 on the connecting rod 71. Then, install the machining assembly 1 on the displacement rod 64, with one end of the machining assembly 1 against the side wall of the connecting plate 61. Then, put the two locking assemblies 2 on the two displacement rods 64 respectively, so that one end of the locking assembly 2 abuts against the machining assembly 1 to limit the movement of the machining assembly 1 and prevent the machining assembly 1 from sliding along the displacement rod 64 during the machining process, thus ensuring that the machining position does not shift.After all components are installed, the rotary motor 14 is connected to the power supply to drive the cutter head 12 to rotate. Then, the connecting assembly 6 is manually guided down along the connecting rod 71 to position the cutter head 12 for processing. First, a punching operation is performed on the end cap 4. After punching, the connecting rod 71 is rotated using the tapered roller bearing 73 and the ball bearing 74, causing it to rotate in a circular motion. During this rotation, the connecting rod 71 carries the connecting assembly 6 and the processing assembly 1 to rotate synchronously. As the processing assembly 1 moves slowly, the rotating cutter head 12 mills a circular sealing groove on the end cap 4. Utilizing these structural features, the center of the driving assembly 7 is aligned with the center of the end cap 4. This ensures that the circular sealing groove is concentric with the circular end cap 4. This neat circular sealing groove, after installing the O-ring and connecting it to the motor, not only guarantees a sealing effect but also prevents misalignment that could prevent proper installation. Another point is that the driving connecting rod 71 should be rotated slowly to ensure a consistent depth throughout the circular sealing groove. The entire device has advantages in terms of disassembly and assembly, ease of use, and size, effectively solving the problem that users cannot independently process the four circular sealing grooves on the end caps.
[0070] In a specific embodiment, such as Figure 2 The suction cup assembly 3 includes a permanent magnet 31, adjusting bolts 32, a base 33, a switch 34, and a tray 35. Several adjusting bolts 32 are mounted on the surface of the base 33, and the permanent magnet 31 is mounted on the upper surface of the base 33. The adjusting bolts 32 are located around the permanent magnet 31. The switch 34 is mounted on the side surface of the permanent magnet 31, and the tray 35 is mounted on the upper end of the permanent magnet 31. The permanent magnet 31 is generally made of steel or iron, while the switch 34 is made of neodymium. Neodymium magnets are strong magnets. When the switch 34 rubs against the permanent magnet 31, the magnetic domains in the permanent magnet 31 are rearranged, causing the permanent magnet 31 to generate magnetic attraction and limit the end cap 4. The purpose of setting the adjusting bolts 32 on the base 33 is to allow the adjustment bolts 32 to extend out of the base 33 to level the surface when the placement plane is uneven, ensuring that the entire device is level during processing.
[0071] In a specific embodiment, such as Figures 3-5The three-jaw chuck 5 includes an installation space 51, a column 52, jaws 53, a drive head 54, a connecting housing 55, a helical gear 56, a conical gear ring 57, a circular hole 58, and a threaded structure 59. The upper end of the connecting housing 55 has an installation space 51. The column 52 is installed on the upper surface of the bottom plate of the connecting housing 55. The top surface of the column 52 has a circular hole 58 that extends downward and passes through the bottom plate of the connecting housing 55. Several 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, which is located in the installation space 51. The conical gear ring 57 is fitted on the outside of the column 52. A rack is provided on the side surface of the conical gear ring 57, which meshes with the helical gear 56. The bottom of the conical gear ring 57 is a threaded structure 59. Several jaws 53 are connected to the bottom of the connecting housing 55. The usage of the three-jaw chuck 5 has been explained in detail in the specific usage instructions. The structure of the three-jaw chuck 5 is basically similar to that of existing three-jaw chuck 5s. However, unlike existing three-jaw chuck 5s, the method used in this application is different. Most three-jaw chuck 5s are clamped onto the outside of the workpiece for holding purposes. In this device, the three-jaw chuck 5, while satisfying the clamping requirement, is aligned with the center of the end cover 4. This arrangement ensures that the position where the bottom of the processing component 1 is aligned with the end cover 4 remains the same from the center of the end cover 4, regardless of how the processing component 1 rotates along the drive component 7. This ensures that the processed sealing groove is concentric with the end cap 4. Furthermore, the dual limiting mechanism of the three-jaw chuck 5 and the suction cup assembly 3 prevents the end cap 4 from shifting during processing. Because the suction cup assembly 3 can hold the material, the end cap 4 can be placed anywhere on it. As long as the three-jaw chuck 5 is aligned with the center of the end cap 4, processing can be achieved even if the end cap 4 is not placed at the center of the suction cup assembly 3. Simultaneously, the weight of the processing component 1, connecting component 6, and drive component 7 mounted on the three-jaw chuck 5 presses down on the end cap 4, preventing tilting during processing. The installation space 51 is used to install the conical gear ring 57, while the column 52 is used to fit the conical gear ring 57, allowing it to rotate along the column 52 and preventing translational shift during use.
[0072] In a specific embodiment, such as Figure 6The drive assembly 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 on the outside of the connecting rod 71. The tapered roller bearing 73 is also sleeved on the connecting rod 71. The ball shaft 74 and the tapered roller bearing 73 are respectively positioned on the upper and lower sides of the dividing plate 72, with the ball shaft 74 positioned above the tapered roller bearing 73. The housing 75 is sleeved on the outside of 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 of the three-jaw chuck 5. In use, the drive assembly 7 utilizes the tapered roller bearing 73 and the ball shaft 74 to cause the connecting rod 71 to rotate. The dividing plate 72 is designed to prevent mutual interference between the two bearings. The housing 75 is used to secure the drive assembly 7 to the three-jaw chuck 5 with bolts, preventing displacement of the drive assembly 7 during processing.
[0073] In a specific embodiment, such as Figure 7 The connecting assembly 6 includes a connecting plate 61, an extension plate 62, a sleeve 63, a displacement rod 64, a pad 65, and a cylinder 66. The sleeves 63 are installed on both ends of the connecting plate 61. The right end of the sleeve 63 is a partition structure. The extension plate 62 is installed on the outer surface of the partition structure. The cylinder 66 is installed on the upper and lower surfaces of the connecting plate 61. The cylinder 66 has an installation hole that penetrates the connecting plate 61. The pad 65 is installed on the wall of the installation hole. The displacement rods 64 are arranged in pairs and installed in the two sleeves 63. The processing assembly 1 and the locking assembly 2 are installed on the displacement rods 64. The connecting plate 61 is used to connect the sleeve 63 and the cylinder 66. The cylinder 66 is designed so that the entire connecting assembly 6 can be connected to the connecting rod 71 and can move up and down along the connecting rod 71. The pad 65 is designed to increase the friction at the connection between the connecting assembly 6 and the connecting rod 71. This prevents the connecting assembly 6 from moving down along the connecting rod 71 during processing after the position of the connecting assembly 6 is determined. The extension plate 62 and the partition structure are designed to bring the two sleeves 63 closer together. After they are close together, the displacement rod 64 can be clamped to prevent the displacement rod 64 from moving during processing.
[0074] In a specific embodiment, such as Figure 8 The machining component 1 includes a connecting plate 11, a cutter head 12, a connecting cylinder 13, and a rotary motor 14. Connecting cylinders 13 are mounted on both sides of the connecting plate 11 and are fitted onto the displacement rod 64. The rotary motor 14 is mounted on the connecting plate 11, and the cutter head 12 is mounted on its bottom output end. The machining component 1 is a commonly used milling cutter. Combined with the connecting plate 11 and connecting cylinder 13, the milling cutter is connected to this device to achieve portable machining of the end cap 4. The connecting cylinder 13 connects the machining component 1 to 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, and the inner sleeve 23 is installed inside the inner conical sleeve 22. Several round holes are opened on the side wall of the inner sleeve 23, and 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. The purpose of installing the locking assembly 2 is to limit the position of the processing assembly 1, thereby ensuring that the processing position does not change. The locking assembly 2 is placed on the displacement rod 64, and after one end of the locking assembly 2 is pressed against the processing assembly 1, the pull cap 25 is pulled, causing the inner cone sleeve 22 to be displaced. Using the cone-shaped structure of its inner surface, the limiting ball 24 is pushed outward from the round hole. In this way, the limiting ball 24 slowly approaches and presses against the displacement rod 64. When the limiting ball 24 and the displacement rod 64 are pressed together, the limiting of the entire locking assembly 2 is completed, and the limiting of the processing assembly 1 is also achieved.
[0076] In a specific embodiment, such as Figures 10-11The connecting component 6 also 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. The clamping spring 611 is installed in the displacement groove 612. The clamping rod 610 is connected to the end of the clamping spring 611. The clamping rod 610 is drivenly connected in the displacement groove 612. A limiting hole is formed on the left end surface of the sleeve 63. A rectangular hole 67 is formed on the side of the limiting hole. The limiting hole communicates 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. The rectangular limiting block 68 is connected to the outer end of the limiting ring 69. There is a problem with the structure shown in the above embodiments: since the lengths of the connecting plate 61 and the sleeve 63 are fixed, but one end of the processing component 1 must abut against the connecting plate 61 and the sleeve 63, the installation position of the processing component 1 is fixed, and punching can not be performed on other parts of the end cap 4. If other parts are to be processed, a shim needs to be added between the processing component 1 and the sleeve 63. However, the shim needs to be processed, and self-processed shims inevitably have errors, resulting in inconsistent lengths, ultimately making it impossible to guarantee the installation position of the processing component 1. Therefore, this device provides an alternative approach: adding a displacement groove 612 to the sleeve 63. The displacement groove 612 is located between the inner and outer surfaces of the sleeve 63, which does not affect the contact between the inner surface of the sleeve 63 and the displacement rod 64. The clamping rod 610 is displaced in the displacement groove 612, and a clamping spring 611 is set between the displacement groove 612 and the clamping rod 610. In the first position, a portion of the clamping rod 610 extends out of the sleeve 63. When the processing component 1 is installed, its movement drives the clamping rod 610 to move inward toward the sleeve 63, compressing the clamping spring 611. Once the position is determined, the clamping spring 611 is fixed in place by the locking component 2. At this point, the clamping spring 611 is compressed, and its elastic force is applied to the clamping rod 610, causing one end of the clamping rod 610, along with the limiting ring 69 and the rectangular limiting block 68, to press against the processing component 1. This achieves the limiting of the processing component 1. Using this clamping method, the processing component 1 can be fixed at any position on the displacement rod 64 to enable processing at different positions of the end cap 4. The rectangular hole 67 and the limiting hole are designed to limit the entry depth of the clamping rod 610, while the rectangular limiting block 68 and the limiting ring 69 can 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 12-15The suction cup assembly 3 also includes displacement holes 36, clamping members 37, and insertion holes 38. Insertion holes 38 are formed on the upper surface of the storage tray 35. Four displacement holes 36 are arranged around the insertion holes 38, and clamping members 37 are drivenly connected to the displacement holes 36. The clamping member 37 includes a top block 371, a sleeve rod 372, a drive rod 373, a clamping spring 374, a mounting plate 375, a clamping block 376, a movable rod 377, a drive spring 378, and a locking block 379. One end of the drive rod 373 is drivenly connected to the storage tray 35 and has a locking block 379 at its end. The other end of the drive rod 373 is fitted with a mounting plate 375. The clamping spring 374... A clamping spring 374 is installed between the mounting plate 375 and the end of the displacement hole 36, and a sleeve rod 372 is installed on the mounting plate 375. A top block 371 is installed on one end of the sleeve rod 372. The outer surface of the top block 371 is set with a convex structure. A collar is set on the outer surface of the other end of the sleeve rod 372 and a retaining ring is set inside. One end of the movable rod 377 is connected to a clamping block 376. One end of the clamping block 376 is set with an arc-shaped structure. The other end of the movable rod 377 is set with a driving spring 378 and a limit 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, the problem of not being able to place the end cap 4 in the center of the storage tray 35 is addressed by providing an alternative solution: an insertion hole 38 is made on the storage tray 35, and an extension rod 76 is set at the bottom of the connecting rod 71. Then, a movable clamping member 37 is set in the displacement hole 36 on the side of the insertion hole 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 insertion hole 38. The clamping member 37 is used to clamp the extension rod 76 while simultaneously centering and limiting the end cap 4 again, ensuring that the end cap 4 is correctly positioned during processing. There are two methods for using the clamping member 37: one is to first connect the end cap 4 to the suction cup assembly 3, and the other is to first connect the end cap 4 to the three-jaw chuck 5. For the first installation method, before activating the suction cup assembly 3, place the end cap 4 on the storage tray 35. Here, we will describe the different diameters of the central hole in the end cap 4. Firstly, for the smaller diameter, it is necessary to simultaneously pull the four clamping components 37 to move them closer together, allowing them to pass through the central hole. During the movement of the clamping components 37, the clamping spring 374 undergoes tensile deformation and generates elastic force. When the clamping components 37 are released, they move away from each other under the action of the spring. During this movement, the top block 371 gradually approaches and abuts against the inner wall of the central hole. Depending on the diameter of the central hole, in some cases, the clamping component 37 may not return to its original position after the top block 371 abuts. If the clamping component 37 moves further, the sleeve rod 372 will move along the mounting plate 375. At this point, a smaller diameter extension rod 76 needs to be inserted, because when the extension rod 76 is inserted, its side will drive the movable rod 377 to move.When the sleeve rod 372 cannot move, the movable rod 377 can only move inwards towards the sleeve rod 372, compressing the drive spring 378. However, the compression of the drive spring 378 is limited. If the diameter of the extension rod 76 is too large, it will cause the movable rod 377 to shift, exceeding the elastic limit of the drive spring 378. But if the diameter of the extension rod 76 is appropriate, the movement of the movable rod 377 will compress the drive spring 378 to a certain extent. In this case, the drive spring 378 remains compressed, and the elastic force is applied to both the movable rod 377 and the sleeve rod 372, allowing the clamping block 376 and the top block 371 to better abut. By utilizing multiple identical structures on the extension rod 76 and the central hole, the positions of the connecting rod 71 and the end cap 4 can be finely adjusted again, ensuring that the center positions of the end cap 4 and the connecting rod 71 are consistent, thereby achieving better processing. Furthermore, multiple clamping blocks 376 clamp the extension rod 76. Since the clamping components 37 are positioned identically and all at the center circle, this fine-tuning allows the end cap 4 and the connecting rod 71 to be placed in the center of the tray 35, after which the suction cup assembly 3 can be activated to pick up the material. Alternatively, after some clamping components 37 are engaged, they essentially return to their original positions, at which point a slightly larger diameter material can be used. The purpose of the extension rod 76 is to drive the movable rod 377 to move while the top block 371 is already against the middle hole. Making the extension rod 76 wider allows the movable rod 377 to move more, compressing the drive spring 378. This allows the spring force of the drive spring 378 to be applied to the movable rod 377 and the sleeve rod 372, thus achieving the aforementioned clamping effect. For those with a larger middle hole, the clamping member 37 does not need to be moved when the end cap 4 is placed. However, in this case, an extension rod 76 with a diameter slightly smaller than or equal to the diameter of the insertion hole 38 is needed. This way, when the extension rod 76 is installed, it drives the clamping member 37 to move when inserted. As the objects move away from each other, the clamping spring 374 is compressed, and the pressure is applied to the extension rod 76 to create a limit. At the same time, the extension rod 76 will also cause the movable rod 377 to move along the sleeve rod 372 on the mounting plate 375. During the displacement, the top block 371 gradually approaches and abuts against the wall of the middle hole. After the sleeve rod 372 can no longer move, the movable rod 377 will gradually continue to move inward towards the sleeve rod 372, causing the drive spring 378 to be compressed. The compressed elastic force is applied to the end cover 4 and the extension rod 76 to limit and fine-tune them. Although the three-jaw chuck 5 has been centered once, the second fine-tuning does not conflict. For the second usage scenario, after connecting the end cap 4 to the three-jaw chuck 5, during installation, it is important to note that it is best to first pinch the sleeve rod 372 and the movable rod 377 together when the clamping component 37 enters the central hole. After installation, they will automatically release under the action of spring force, limiting the position of the end cap 4 and the extension rod 76. The use of a double-moving clamping mechanism consisting of the sleeve rod 372, the movable rod 377, and the drive spring 378 can better achieve the effects of limiting and fine-tuning.
