Description

Technical Field

[0001] This utility model relates to the field of linear motor manufacturing technology, and in particular to a U-shaped glue-pouring and shaping tooling for linear motor manufacturing. Background Technology

[0002] A linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. It converts electrical energy directly into linear motion mechanical energy by expanding a closed magnetic field into an open magnetic field. During the production process, the mover of a U-shaped linear motor requires glue filling to meet requirements for insulation, moisture protection, and coil fixation. Uneven glue filling or the presence of air bubbles will affect the motor's performance and lifespan. Using a U-shaped glue filling and shaping fixture can ensure uniform glue filling, avoid air bubble formation, and thus improve product quality.

[0003] After mixing the adhesive, pour it in slowly, carefully observing the flow and for any air bubbles. Then apply pressure to shape the component, controlling the pressure and time precisely. Once the adhesive has cured, release the pressure, remove the mover, and inspect and process it. Proper use of this fixture can improve production efficiency and quality stability.

[0004] In existing technologies, some U-shaped potting and shaping fixtures used in linear motor production encounter U-shaped coil assemblies of different sizes during use. These coil assemblies occupy different positions within the motor and bear different forces. Since the size of the coil assemblies is uncontrollable, it's impossible to guarantee their correct installation position and fixation method within the motor after potting and shaping, reducing the flexibility of the U-shaped potting and shaping fixture. Therefore, to address these shortcomings, a new U-shaped potting and shaping fixture for linear motor production is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a U-shaped glue-filling and shaping fixture for linear motor production, aiming to improve the problem that some existing U-shaped glue-filling and shaping fixtures for linear motor production suffer from reduced flexibility during use due to the inability to restrict U-shaped coil groups of different sizes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A U-shaped glue-filling and shaping fixture for linear motor production includes a support frame, a product placement plate, and two side plates. Auxiliary frames are fixedly connected to both the front and rear sides of the support frame. A drive assembly is fixedly connected to the inner wall of the support frame. Rotating plates are rotatably connected to both the front and rear ends of the drive assembly. Opening blocks are rotatably connected to the distal ends of the two rotating plates. Support plates are fixedly connected to the distal sides of the two opening blocks. Limit blocks are fixedly connected to the bottom side of the support plate. Opening plates are rotatably connected to both the left and right ends of the support plate. Transmission plates are rotatably connected to the distal ends of multiple opening plates.

[0012] As a further description of the above technical solution:

[0013] The front and rear ends of the push block are respectively rotatably connected to the adjacent ends of the two rotating plates, and a limit opening is provided on the bottom side of the inner wall of the support frame.

[0015] The two limiting blocks are externally slidably connected to the inside of the limiting opening, the inside of the support frame is in contact with the outside of the product placement plate, and the two rotating columns are externally rotatably connected to the inside of the auxiliary frame.

Then the positioning plate will slide away from the inside of the connecting frame, at which point the side plate can be removed to facilitate the picking up of the product, thereby improving work efficiency.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a U-shaped potting and shaping fixture for linear motor production, comprising a support frame 1, a product placement plate 19, and two side plates 21. The support frame 1 and the product placement plate 19 cooperate to restrict the U-shaped coil assembly. Auxiliary frames 2 are fixedly connected to both the front and rear sides of the support frame 1, and are fixed by welding to provide support for the two auxiliary frames 2. A rectangular limit opening 3 is provided on the bottom side of the inner wall of the support frame 1. A drive assembly, including a cylinder 4, is fixedly connected to the inner wall of the support frame 1. The cylinder 4 provides a drive source. The cylinder 4 is externally fixedly connected to the inside of the support frame 1 and fixed by welding to ensure stable operation. A push block 5 is fixedly connected to the drive end of the cylinder 4, and the push block 5 is driven to slide by starting the cylinder 4. Rotating plates 6 are rotatably connected to both the front and rear ends of the drive assembly. The front and rear ends of the push block 5 are respectively rotatably connected to the adjacent ends of the two rotating plates 6, and the sliding force is transmitted to the two rotating plates 6 through the push block 5 to rotate.

[0033] Two rotating plates 6 are each rotatably connected to an open block 7 at their distal ends, allowing the open blocks 7 to slide as the rotating plates 6 rotate. A support plate 8 is fixedly connected to the distal ends of the two open blocks 7, transmitting the sliding force to the support plate 8 through the open blocks 7. A limit block 9 is fixedly connected to the bottom of the support plate 8 via welding, providing support for the limit block 9. The two limit blocks 9 are externally slidably connected to the inside of the limiting opening 3, allowing the limit blocks 9 to slide horizontally. Open plates 10 are rotatably connected to both ends of the support plate 8, transmitting the sliding force to the two open plates 10 for rotation. A transmission plate 11 is rotatably connected to the distal ends of the multiple open plates 10, transmitting the rotational force to the transmission plate 11, causing it to rotate. A rotating column 12 is fixedly connected inside the transmission plate 11, transmitting the rotational force to the rotating column 12 through the transmission plate 11. The two rotating columns 12 are externally rotatably connected to the inside of the auxiliary frame 2. The auxiliary frame 2 restricts the rotation of the rotating columns 12, preventing them from shifting.

[0034] A push plate 13 is fixedly connected to the outside of the rotating column 12, and the rotating column 12 drives the push plate 13 to rotate synchronously. A fixed plate 14 is fixedly connected to the outside of the push plate 13, and the push plate 13 drives the fixed plate 14 to rotate synchronously. A drive shaft 15 is fixedly connected to the outside of the fixed plate 14, and the fixed plate 14 transmits the rotational force of the push plate 13 to the drive shaft 15. An adjusting plate 16 is slidably connected to the outside of the drive shaft 15, and the drive shaft 15 transmits the rotational force to the adjusting plate 16, allowing the adjusting plate 16 to slide horizontally. T-shaped openings 17 are provided on the far sides of the two adjusting plates 16, providing space for the drive shaft 15 to move. The two fixed plates 14 are slidably connected to the inside of the T-shaped openings 17, allowing the fixed plates 14 to rotate stably. Multiple square plates 18 are fixedly connected to the bottom side of the adjusting plate 16. These square plates are fixed by welding to support the square plates 18 and to constrain U-shaped coil assemblies of different sizes. The interior of the support frame 1 contacts the exterior of the product placement plate 19, providing support for the product placement plate 19. Two connecting frames 20 are fixedly connected to both the left and right sides of the support frame 1, and are fixed by welding to support the connecting frames 20.

[0035] Reference Figure 1 , Figure 2 and Figure 4A transmission assembly is rotatably connected inside the side plate 21. The transmission assembly includes a rotating rod 22, which is rotatably connected to the outside of the side plate 21. The rotating rod 22 can rotate due to the constraint of the side plate 21. A handle 23 is fixedly connected to the far side of each of the two rotating rods 22, allowing the rotating rods 22 to rotate synchronously by gripping the handle 23. An elliptical plate 24 is fixedly connected to the near side of each of the two transmission assemblies. The near side of each of the two rotating rods 22 is fixedly connected to the far side of each of the two elliptical plates 24, transmitting the rotational force to the elliptical plates 24 through the rotating rods 22. Positioning rods 25 are fixedly connected to both the upper and lower ends of the side plate 21 by welding, providing support for the positioning rods 25.

[0036] A spring 26 is fitted around the outside of the positioning rod 25. By restricting the spring 26, the force on the spring 26 can be evenly distributed. Two sliding plates 27 are slidably connected to the outside of the two positioning rods 25. Guided by the positioning rods 25, the sliding plates 27 can slide stably. The spring 26 is fixed to the sliding plates 27, so that the spring 26 transmits the return force to the sliding plates 27. The outside of the elliptical plate 24 contacts the adjacent side of the two sliding plates 27. During the rotation of the elliptical plate 24, it pushes the two sliding plates 27 to slide to the opposite side. Positioning plates 28 are fixedly connected to the opposite side of the two sliding plates 27. The sliding force of the sliding plates 27 is transmitted to the square plate 18. The outside of the positioning plates 28 is slidably connected to the inside of the connecting frame 20. By sliding the positioning plates 28 into the connecting frame 20, support is provided for the positioning plates 28. The outside of the two connecting frames 20 is slidably connected to the inside of the side plates 21. By restricting the side plates 21, the connecting frames 20 can slide stably into the side plates 21 for installation.

[0037] Working principle: Based on U-shaped coil groups of different sizes, the cylinder 4 drives the push block 5 to slide, thereby driving the two rotating plates 6 to rotate, which in turn drives the two opening blocks 7 to slide towards each other. Then, the opening blocks 7 drive the support plate 8 to slide. The support plate 8 then drives the limiting block 9 and, guided by the limiting opening 3, the two support plates 8 slide towards each other, thereby driving the two opening plates 10 to rotate. Then, the transmission plate 11 rotates, which drives the rotating column 12 to rotate, which in turn drives the push plate 13 to rotate. The force of the fixed plate 14 is transmitted to the transmission shaft 15 through the fixed plate 14. Then, the transmission shaft 15 pushes the adjusting plate 16 to slide. The two adjusting plates 16 drive multiple square plates 18 to slide towards each other and slide along the product placement plate 19, so that the distance between the relative square plates 18 can be adjusted to accommodate U-shaped coil groups of different sizes and to limit them, thereby improving the flexibility of the device.

[0038] After placing the U-shaped coil assembly inside the product placement plate 19, the surface of the product placement plate 19 is potted with glue and then placed in a heating box for stabilization. After stabilization, it is removed, and the handle 23 is gripped to apply rotational force, thereby driving the rotating rod 22 to rotate, which in turn drives the elliptical plate 24 to rotate. Then, it no longer presses against the two sliding plates 27, and the spring 26 in a compressed state is reset and drives the sliding plates 27 to slide, causing the two opposing sliding plates 27 to slide towards each other, thereby driving the positioning plate 28 to slide. Then the positioning plate 28 will slide away from the inside of the connecting frame 20. At this time, the side plate 21 can be removed to facilitate product handling, thereby improving work efficiency.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
