[0002] Linear motors have the advantages of simple structure, high positioning accuracy, fast response speed, safe and reliable operation, etc., and are widely used in transportation, CNC machining and other industries. At present, common linear motors are divided into cylindrical linear motors, U-shaped slot linear motors and flat linear motors. Among them, U-shaped slot linear motors generally use ironless technology, with the advantages of large thrust, strong overload capacity, no cogging force, no electromagnetic suction and smooth operation, and are increasingly widely used in various industries.

[0003] The internal coil winding of the U-shaped slot linear motor is generally formed by stacking three annular coils and extruding them, and the overall shape is rectangular. Since the internal coil winding of the U-shaped slot linear motor has no iron core for positioning, it needs to be shaped and fixed with glue, which requires the use of a shaping device to realize the shaping of the coil winding.

[0004] At present, common coil winding shaping devices mainly include a shaping base plate, a shaping cover plate, a shaping cover plate, a shaping base plate and a pin; a profiling groove is opened in the middle area of ​​the shaping base plate, and the shaping base plate is fixedly connected in the profiling groove by fastening screws; pins are evenly arranged in the middle area of ​​the shaping base plate, and the shaping cover plate passes through the pins and presses on the coil winding, and the shaping cover plate presses on the shaping cover plate. When the coil winding shaping process is performed, an external force is applied to the shaping cover plate, and the shaping cover plate resists the shaping cover plate, so that the shaping cover plate presses the coil winding on the shaping base plate to achieve the shaping of the coil winding.

[0005] After the existing coil winding shaping device performs a shaping process, the shaping cover plate, the shaping cover plate and the shaped coil winding will all sink into the profiling slot, which requires manual lifting of the shaping cover plate and the shaping cover plate before the shaped coil winding can be removed. Especially when the size of the profiling slot is small, such a structural setting is not convenient for reaching into the profiling slot to take out the shaped coil winding. Summary of the invention The present application provides a coreless coil shaping device, the purpose of which is to improve the structure of the shaping device and facilitate the removal and installation of the coil.

[0006] The present application provides a coreless coil shaping device that adopts the following technical solution: A coreless coil shaping device comprises a base, one side of which is provided with a profiling groove, and the profiling groove penetrates the base along the length direction of the base; a wire fixing plate, the wire fixing plate is located in the profiling groove, and the wire fixing plate is slidably connected to the base along the depth direction of the profiling groove, a return spring is arranged between the wire fixing plate and the groove bottom of the profiling groove, one end of the return spring is connected to the wire fixing plate, and the other end is connected to the groove bottom of the profiling groove; a wire fixing component for fixing the coil is arranged on the side of the wire fixing plate away from the return spring; a shaping pressure plate, the shaping pressure plate is located on the side of the wire fixing plate away from the return spring, and the shaping pressure plate is pressed on the wire fixing plate; a cover plate, the cover plate is arranged on the side of the shaping pressure plate away from the wire fixing plate, and the cover plate is in conflict with the shaping pressure plate.

The cover plate 4 is connected to an external press, and the press is started. Under the continuous pressure of the press, the cover plate 4, the shaping plate 3 and the wire fixing plate 2 all move downward until the position of the wire fixing plate 2 is fixed. At this time, the press continues to apply pressure, and the shaping plate 3 squeezes and shapes the several coils on the wire fixing plate 2. During this process, the several coils are shaped into the required state with the cooperation of the profiling groove 11, the shaping plate 3 and the wire fixing plate 2. Through the coordinated arrangement of the base 1, the wire fixing plate 2, the shaping plate 3 and the cover plate 4, the function of the shaping device is met, and the shaping processing of the coreless coil can be realized.

[0070] Reference Figure 6 The contact plate 41 on the lower side of the cover plate 4 is detachably connected to the shaping plate 3. Specifically, the contact plate 41 is connected to the shaping plate 3 by bolts.

[0071] Since the contact plate 41 is connected to the shaping pressure plate 3, when the yield spring 75 contacts the cover plate 4 to reset, the shaping pressure plate 3 is reset synchronously, which enables the cover plate 4 and the shaping pressure plate 3 to be separated from the guide column 53 in the vertical direction at the same time, which makes it easy to pull the slide 12 and the wire fixing plate 2 out of the profiling groove 11.

[0072] Reference Figure 5 and Figure 6Auxiliary slides 8 are provided on both sides of the base 1 in the length direction, and auxiliary slides 8 are provided on the auxiliary slides 8. The auxiliary slides 81 penetrate the auxiliary slides 8 along the length direction of the base 1, and one side of the auxiliary slides 81 in the length direction is connected to the profiling groove 11. The slide 12 is plugged into the auxiliary slides 81, and the slide 12 is slidably connected to the inner wall of the auxiliary slides 81 along its own length direction.

[0073] The auxiliary slide 8 enables the slide 12 to slide out of the base 1 , which makes it easy for the slide 12 to slide from the auxiliary slide 8 into the base 1 , thus facilitating the extraction or insertion of the wire fixing plate 2 .

[0074] Reference Figure 5 and Figure 6 A replacement platform 9 is provided on one side of the length direction of the slide 12. The structure of the replacement platform 9 is the same as that of the slide 12, and a fixed wire plate 2 and a guide reset assembly 5 are also provided on the replacement platform 9. One end of the replacement platform 9 in the length direction is detachably connected to the slide 12. Specifically, the replacement platform 9 is connected to the slide 12 by bolts.

[0075] Since the replacement table 9 is connected to the slide table 12 , the slide table 12 and the replacement table 9 can move synchronously.

[0076] Reference Figure 5 and Figure 6 The replacement platform 9 is arranged on the auxiliary slide 8, and the replacement platform 9 is plugged into the auxiliary slide 81, and the replacement platform 9 is slidably connected with the inner wall of the auxiliary slide 81 along its own length direction. In addition, the replacement platform 9 is plugged into the profiling groove 11, and the replacement platform 9 is slidably connected with the inner wall of the profiling groove 11 along its own length direction.

[0077] Since the replacement table 9 is the same as the slide 12, when the slide 12 is pulled out from the profiling groove 11, the replacement table 9 is automatically inserted into the profiling groove 11, and the wire fixing plate 2 on the slide 12 can realize the unloading and loading of the coil, while the wire fixing plate 2 on the replacement table 9 can realize the shaping of the coil. Similarly, when the slide 12 is pushed into the profiling groove 11, the replacement table 9 automatically slides out from the profiling groove 11, and the wire fixing plate 2 on the replacement table 9 can realize the unloading and loading of the coil, while the wire fixing plate 2 on the slide 12 can realize the shaping of the coil.

[0078] Reference Figure 5 A limit plate 82 is provided at one end of the auxiliary slide 8 away from the base 1, and the limit plate 82 is connected to the corresponding auxiliary slide 8. The limit plate 82 is arranged opposite to the replacement table 9 or the slide table 12 along the length direction of the auxiliary slide 8, and the limit plate 82 closes the auxiliary slide groove 81.

[0079] The setting of the limiting plate 82 can limit and position the replacement table 9 or the slide 12. On the one hand, it ensures that when the slide 12 or the replacement table 9 slides out of the profiling groove 11, the slide 12 or the replacement table 9 will not slide out of the corresponding auxiliary slide groove 81, thereby realizing the limiting function. On the other hand, when the slide 12 slides out of the profiling groove 11, one end of the slide 12 hits the corresponding limiting plate 82, and then the replacement table 9 just slides into the profiling groove 11, which can ensure the accurate positioning of the replacement table 9; on the contrary, it can ensure the accurate positioning of the slide 12, thereby realizing the positioning function.

[0080] Reference Figure 5 , a magnet 83 is provided on the side of the limit plate 82 facing the base 1, and the slide 12 and the replacement table 9 are made of magnetic materials or materials that can be attracted by the magnet 83. When one end of the slide 12 or the replacement table 9 contacts the limit plate 82, the magnet 83 can attract the slide 12 or the replacement table 9, which can ensure that the slide 12 or the replacement table 9 is tightly pressed against the limit plate 82, thereby improving the positioning accuracy of the slide 12 and the replacement table 9. In addition, during the shaping operation, the slide 12 or the replacement table 9 in the profiling groove 11 can be prevented from shifting.

[0081] The implementation principle of the embodiment of the present application is as follows: when the slide 12 is located in the profiling groove 11, the press is started, and the cover plate 4 and the shaping plate 3 are lowered together to achieve the shaping of the coil. After the shaping is completed, the press is reset, and the cover plate 4 and the shaping plate 3 are raised together with the cooperation of the yield spring 75 until the shaping plate 3 is separated from the guide column 53. When the slide 12 is in the profiling groove 11 and the coil is being shaped, the coil is manually installed on the wire fixing plate 2 on the replacement table 9.

[0082] The slide 12 is pushed so that the slide 12 slides out from the base 1 and slides onto the corresponding auxiliary slide 8, and the magnet 83 on the corresponding limit plate 82 is attracted to one end of the slide 12. At the same time, the replacement table 9 slides from the corresponding auxiliary slide 8 into the profiling groove 11. At this time, the press is started to shape the coil on the replacement table 9. When the replacement table 9 is in the profiling groove 11 and the coil is shaped, the coil is manually installed on the fixed wire plate 2 on the slide.

[0083] Repeat the above steps, so that when the slide 12 is in the profiling groove 11 to shape the coil, the wire fixing plate 2 on the replacement table 9 is used to unload the shaped coil and load the coil to be shaped; similarly, when the replacement table 9 is in the profiling groove 11 to shape the coil, the wire fixing plate 2 on the slide 12 is used to unload the shaped coil and load the coil to be shaped. This can continuously load, shape and unload the coil, improve the shaping speed of the coil, and facilitate the unloading and loading of the coil.

[0084] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
