Description

Technical Field

[0001] This utility model relates to the field of electromagnetic coil processing technology, and in particular to a clamping device for electromagnetic coil processing. Background Technology

[0002] Electromagnetic coils are created by utilizing the magnetic field that exists around a conductor. Winding the coil into a spiral shape strengthens the magnetic field, achieving the highest magnetic field strength with minimal space. Using a conductor coated with insulating varnish instead of a regular conductor also saves space. Electromagnetic coils are widely used in various industries in today's society. Clamping is required during the processing of electromagnetic coils.

[0003] In the existing electromagnetic coil processing device, the existing clamping device has certain drawbacks. If it cannot effectively clamp and fix insulating sleeves of different sizes, the sleeve may shake or shift when the winding machine starts winding due to insecure fixation. Since it cannot clamp insulating sleeves of different sizes, it may be necessary to change different clamps or make complex adjustments to the clamps whenever processing insulating sleeves of different sizes. This will greatly increase preparation time and reduce production efficiency. Therefore, we propose a clamping device for electromagnetic coil processing to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a clamping device for processing electromagnetic coils, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A clamping device for processing electromagnetic coils includes: a frame, two sets of movable blocks slidably mounted on the top of the frame, movable brackets fixedly mounted on the top of each set of movable blocks, annular rotating seats fixedly mounted on one side of each set of movable brackets, annular bases rotatably mounted on the outer sides of each set of annular rotating seats, a driving disc and a driven disc fixedly mounted on one side of each set of annular bases, a driving motor fixedly mounted on one side of one set of movable brackets, a fixed frame and a driving motor fixedly mounted on one side of the driving disc, the fixed frame fixedly mounted on the output end of the driving motor, a screw rotatably mounted inside the driving disc, a threaded sleeve threadedly connected to the outer side of the screw, four sets of outer support plates slidably mounted on one side of the driving disc, two sets of support rods hinged between each of the four sets of outer support plates and the outer side of the threaded sleeve, anti-slip pads fixedly mounted on the outer sides of the multiple sets of outer support plates, and insulating sleeves movably abutting against the outer sides of the multiple sets of anti-slip pads.

[0007] Preferably, a bidirectional lead screw and a worm gear are rotatably installed inside the frame, two sets of moving blocks are threadedly connected to the outside of the bidirectional lead screw, a turntable is rotatably installed on one side of the frame, the turntable is fixedly installed at one end of the worm gear, and a worm wheel is fixedly installed on the outside of the bidirectional lead screw.

[0008] Preferably, four sets of sliding grooves are provided on one side of the drive disc, and the four sets of outer support plates are slidably installed in the corresponding sliding grooves.

[0009] Preferably, a fixing pin is provided inside the driven disc, and the fixing pin is adapted to one end of the screw.

[0010] Preferably, the screw is fixedly installed on the output end of the active motor, and each of the multiple sets of annular bases has a rotating rail inside, with two sets of annular rotating seats rotatably installed in the corresponding rotating rails.

[0011] Preferably, the worm gear and the worm are meshed with each other, and the top of the frame is provided with two sets of slide tracks, in which the two sets of moving blocks are slidably installed.

[0012] In this invention, a clamping device for processing electromagnetic coils is described. A turntable drives a worm gear to rotate, which in turn drives a bidirectional lead screw to rotate. This causes two sets of moving blocks to move relative to each other within a slide rail inside the frame. This, in turn, brings the two sets of moving supports closer together, allowing the screw to be inserted into a fixing pin within the driven disc for fixation. Because the mechanical transmission has a fixed transmission ratio, each turntable rotation corresponds to a predictable movement of the two sets of moving blocks within the slide rail. When the two sets of moving supports approach each other, the screw can be precisely inserted into the fixing pin within the driven disc, ensuring accurate connection. This is crucial for the subsequent stable operation of the entire device. Conversely, releasing the fixing pin from the driven disc facilitates the subsequent removal of the insulating sleeve. This simple operation process, compared to complex manual disassembly or multiple independent operations to unlock, greatly reduces the difficulty for operators and improves operational convenience.

[0013] This utility model has a reasonable structural design. An active motor drives a screw to rotate within a drive disc. The screw, through its threaded relationship with the threaded sleeve, allows the sleeve to move left and right. A support rod then drives an outer support plate to move radially along a groove within the active disc. This movement causes anti-slip pads to clamp and fix the insulating sleeve. Through the cooperation of the driven disc and the screw, the drive motor drives the fixed frame and the drive disc to rotate within the base and the annular rotating seat. This, in turn, causes multiple sets of outer support plates, anti-slip pads, and the insulating sleeve to rotate. The relative fixation between the screw and the driven gear drives the driven disc to rotate synchronously with the cooperation of the base and the annular rotating seat, thereby achieving more stable winding of the insulating sleeve. This effectively prevents local deformation or damage to the insulating sleeve during clamping, ensuring the integrity and stability of the insulating sleeve and providing a solid foundation for subsequent winding and other processing operations. This design ensures high movement accuracy of the threaded sleeve, making the position adjustment of the outer support plate more accurate. For insulating sleeves of different sizes, very fine clamping adjustments can be achieved, improving the adaptability and stability of clamping. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4 A clamping device for processing electromagnetic coils includes: a frame 1, two sets of movable blocks 2 slidably mounted on the top of the frame 1, movable brackets 3 fixedly mounted on the top of each set of movable blocks 2, annular rotating seats 7 fixedly mounted on one side of each set of movable brackets 3, annular bases 8 rotatably mounted on the outer side of each set of annular rotating seats 7, a driving disk 9 and a driven disk 15 fixedly mounted on one side of each set of annular bases 8, a drive motor 4 fixedly mounted on one side of one set of movable brackets 3, and a fixed drive disk 15 on one side of the drive disk 9. A fixed frame 5 and an active motor 6 are installed. The fixed frame 5 is fixedly installed on the output end of the drive motor 4. A screw 10 is rotatably installed inside the drive disc 9. A threaded sleeve 11 is threadedly connected to the outside of the screw 10. Four sets of external support plates 13 are slidably installed on one side of the drive disc 9. Two sets of support rods 12 are hinged between the four sets of external support plates 13 and the outside of the threaded sleeve 11. Anti-slip pads 14 are fixedly installed on the outside of the multiple sets of external support plates 13. Insulating sleeves 20 are movably abutted against the outside of the multiple sets of anti-slip pads 14.

[0021] In this embodiment, a bidirectional lead screw 16 and a worm gear 17 are rotatably mounted inside the frame 1. Two sets of moving blocks 2 are threadedly connected to the outside of the bidirectional lead screw 16. A turntable 18 is rotatably mounted on one side of the frame 1. The turntable 18 is fixedly mounted on one end of the worm gear 17. A worm wheel 19 is fixedly mounted on the outside of the bidirectional lead screw 16. When the two sets of moving brackets 3 approach each other, the screw 10 can be accurately inserted into the fixing pin in the driven disc 15 to ensure the accuracy of the connection. This is crucial for the subsequent stable operation of the entire device.

[0022] In this embodiment, four sets of sliding grooves are provided on one side of the drive disc 9, and four sets of outer support plates 13 are slidably installed in the corresponding sliding grooves. The existence of the sliding grooves provides a clear sliding path for the outer support plates 13, ensuring that the outer support plates 13 will not deviate, shake or move or otherwise irregularly, thereby ensuring the stability of the entire device during operation.

[0023] In this embodiment, a fixing pin is provided inside the driven disc 15. The fixing pin is adapted to one end of the screw 10, which saves a lot of time. Especially in the case of mass production or frequent replacement of parts, it can significantly improve production efficiency.

[0024] In this embodiment, the screw 10 is fixedly installed on the output end of the active motor 6, and the interior of multiple sets of annular bases 8 is provided with rotating rails. Two sets of annular rotating seats 7 are rotatably installed in the corresponding rotating rails. Stable power transmission can ensure that the outer support plate 13 can be accurately moved to the required position, thereby improving the working accuracy of the device.

[0025] In this embodiment, the worm gear 19 and the worm 17 mesh with each other, and two sets of slides are provided on the top of the frame 1. Two sets of moving blocks 2 are slidably installed in the corresponding slides. This guiding effect can ensure that the moving blocks 2 move accurately in the predetermined direction under the drive of the bidirectional lead screw 16.

[0026] In this embodiment, during use, the insulating sleeve is placed outside the anti-slip pad 14, and the active motor 6 is started to drive the screw 10 to rotate in the drive disk 9. Then, through the threaded relationship between the screw 10 and the threaded sleeve 11, the threaded sleeve 11 can be driven to move left and right. Then, through the support rod 12, the outer support plate 13 moves in a divergent manner in the groove in the active disk, thereby driving the anti-slip pad 14 to externally support and clamp the insulating sleeve 20. The divergent movement of the outer support plate 13 can evenly apply clamping force to the insulating sleeve 20 from multiple directions, making the force on the insulating sleeve 20 more uniform and avoiding deformation or damage caused by excessive local force. This uniform clamping force can ensure that the insulating sleeve 20 maintains a stable position throughout the entire processing.

[0027] Rotating the turntable 18 drives the worm gear 17 to rotate, which in turn drives the worm wheel 19 to rotate the double-acting screw 16. This causes the two sets of moving blocks 2 to move relative to each other within the slide rails of the frame 1, which in turn causes the two sets of moving brackets 3 to move closer to each other. This allows the screw 10 to be inserted into the fixing pin in the driven disc 15 and fixed thereto. Since the mechanical transmission has a fixed transmission ratio, each rotation of the turntable 18 corresponds to a predictable amount of movement of the two sets of moving blocks 2 within the slide rails. When the two sets of moving brackets 3 move closer to each other, the screw 10 can be accurately inserted into the fixing pin in the driven disc 15, ensuring the accuracy of the connection. This is crucial for the subsequent stable operation of the entire device.

[0028] This starts the drive motor 4, which drives the fixed frame 5 and the drive disc 9 to rotate in the cooperation of the base and the annular rotating seat 7. This, in turn, drives multiple sets of outer support plates 13, multiple sets of anti-slip pads 14 and insulating sleeve 20 to rotate. Through the relative fixation between the screw 10 and the driven gear, the driven disc 15 is driven to rotate synchronously in the cooperation of the base and the annular rotating seat 7. This achieves more stable winding of the insulating sleeve 20. Through the automated clamping and rotation functions, the time and error rate of manual operation are reduced, and the production efficiency is improved. At the same time, the stable winding quality can reduce the scrap rate, reduce the waste of raw materials, and further reduce the production cost.

[0029] After winding is completed, the worm gear 17 is rotated in the reverse direction by the reverse turntable 18, which in turn drives the worm wheel 19 to rotate in the reverse direction, thereby causing the two sets of moving blocks 2 to move away from each other in the slide rails within the frame 1. This, in turn, causes the two sets of moving brackets 3 to move away from each other, thus disengaging the screw 10 from the fixed pin in the driven disc 15 and unlocking it. Then, the active motor 6 is started to reverse and drive the outer support plate 13 to move inward within the active disc, thereby unlocking the insulating sleeve 20 and allowing it to be removed. This simple operation process greatly reduces the difficulty of the operator's work and improves the convenience of operation compared to complex manual disassembly or multiple independent operations to unlock it.
