[0002] In motors, transformers, sensors, and various electromagnetic devices, coils are core components, and their manufacturing precision and structural stability directly affect the performance and lifespan of the equipment. During the winding, curing, or assembly process, coils need to be maintained in shape and pressure uniformity through a pressure-holding mechanism to prevent loosening and deformation due to insufficient pressure, or insulation layer damage and conductor displacement due to excessive pressure.

[0003] Typically, rigid clamps or bolts are used for fixing, resulting in complex structures and poor adaptability. Pressure adjustment requires manual operation, making precise control difficult, especially inefficient in automated production lines. After prolonged use, mechanical parts are prone to pressure attenuation due to wear or fatigue, affecting coil consistency. Therefore, to address this problem, the inventors have proposed a coil pressure-maintaining mechanism. Utility Model Content

[0018] 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.

[0019] like Figure 1-4 As shown, this utility model discloses a coil pressure holding mechanism, including a support assembly, a pressure holding assembly, a feeding assembly, and a driving assembly. The pressure holding assembly is located on the upper surface of the support assembly and is used to apply pressure to the coil. The feeding assembly is located on the upper surface of the support assembly to facilitate the transportation of the coil. The driving assembly is located on the back of the support assembly to facilitate the movement of the feeding assembly. The pressure holding assembly includes a pressure holding cylinder 21 and a pressure holding upper mold 22. The pressure holding cylinder 21 is located on the upper surface of the support assembly, and the pressure holding upper mold 22 is located at one end of the support assembly to facilitate the application of pressure to the coil.

[0020] Specifically, the operator places the coil to be pressure-held on the coil placement plate 32 of the feeding assembly, which is fixed to the feeding plate 31. After starting the drive assembly, the piston rod (not shown) of the drive cylinder 41 (located on the back of the worktable 11) extends, pushing the moving plate 42 (connected between the drive cylinder 41 and the feeding plate 31) to move laterally. The moving plate 42 drives the feeding plate 31 and the coil placement plate 32 above it, causing the sliding block 302 to slide laterally along the sliding guide rail 301 (fixed to the upper surface of the worktable 11), smoothly transporting the coil to the pressure-holding station (i.e., directly below the pressure-holding upper mold 22), completing the automatic feeding and positioning of the coil.

[0021] It also includes a return spring 23, a telescopic rod 24, and a limiting sleeve 25. The return spring 23 is located on the inner wall of the pressure holding upper mold 22 to facilitate the reset of the pressure holding upper mold 22. The telescopic rod 24 is located on the inner wall of the support assembly to facilitate the movement of the pressure holding upper mold 22. The limiting sleeve 25 is located on the upper surface of the support assembly and is sleeved on the inner wall of the telescopic rod 24.

[0022] Specifically, when the coil reaches the pressure holding position, the pressure holding assembly is activated. The piston rod of the pressure holding cylinder 21 (fixed on the fixed plate 101 above the support rod 12) extends downward, pushing the support plate 102 (connecting the pressure holding cylinder 21 and the pressure holding upper mold 22) to move vertically downward. The support plate 102 drives the pressure holding upper mold 22 to descend synchronously through the telescopic rod 24 on the inner side wall. After the pressure holding upper mold 22 contacts the upper surface of the coil, it continuously applies the set pressure (precisely controlled by the pressure adjustment function of the pressure holding cylinder 21).

[0023] During this process, the telescopic rod 24 acts as a transmission component, transmitting the linear motion of the pressure-holding cylinder 21 to the pressure-holding upper mold 22. The limiting sleeve 25 (fitted on the outside of the telescopic rod 24 and fixed to the fixing plate 101) provides rigid guidance to ensure the vertical movement of the pressure-holding upper mold 22, preventing uneven pressure or mechanical wear caused by misalignment. At the same time, the return spring 23 on the inner wall of the pressure-holding upper mold 22 is compressed, storing elastic potential energy to provide power for subsequent reset.

[0024] After the pressure holding is completed, the piston rod of the pressure holding cylinder 21 retracts, causing the support plate 102 and the pressure holding upper mold 22 to rise. At this time, the return spring 23 on the inner wall of the pressure holding upper mold 22 releases the stored elastic potential energy, assisting the pressure holding upper mold 22 to quickly return to its original position (detach from the coil surface), reducing mechanical impact and improving operating efficiency.

[0025] The feeding assembly includes a sliding guide rail 301 and a sliding block 302. The sliding guide rail 301 is located on the upper surface of the support assembly, and the sliding block 302 is located on the inner side wall of the sliding guide rail 301 and can reciprocate laterally relative to the sliding guide rail 301. The upper surface of the sliding block 302 is provided with a feeding plate 31 for conveying materials, and the upper surface of the feeding plate 31 is provided with a coil placement plate 32 for facilitating the placement of materials.

[0026] Specifically, the sliding block 302 is embedded in the sliding guide rail 301, the feeding plate 31 is fixed on the upper surface of the sliding block 302, and the coil placement plate 32 is placed on the feeding plate 31 to support the coil to be held under pressure.

[0027] The drive assembly includes a drive cylinder 41 and a moving plate 42. The drive cylinder 41 is located on the back of the support assembly, and the moving plate 42 is located at one end of the drive cylinder 41. The moving plate 42 is located between the feeding plate 31 and the drive cylinder 41.

[0028] Specifically, the piston rod of the drive cylinder 41 (located on the back of the worktable 11) extends, pushing the moving plate 42 to move laterally. Since the moving plate 42 is connected to the feeding plate 31, the feeding plate 31 slides along the sliding guide rail 301 with the sliding block 302 towards the pressure holding station (below the pressure holding upper mold 22) until the coil accurately reaches the preset pressure holding position.

[0029] The support assembly includes a worktable 11 and support rods 12. Support rods 12 are located on the upper surface of the worktable 11. Multiple support rods 12 are provided and spaced apart. A sliding guide rail 301 is located on the upper surface of the worktable 11. A drive cylinder 41 is located on the back of the worktable 11. A fixing plate 101 is provided on the upper surface of the support rods 12. Multiple fixing plates 101 are provided and spaced apart. A pressure holding cylinder 21 is located on the upper surface of the fixing plate 101. A limiting sleeve 25 is located on the upper surface of the fixing plate 101.

[0030] Specifically, the workbench 11 serves as the basic platform, the support rod 12 and the fixed plate 101 form a frame, the sliding guide rail 301 is fixed to the upper surface of the workbench 11, and the drive cylinder 41 is installed on the back of the workbench 11.

[0031] A support plate 102 is provided at one end of the fixed plate 101. The support plate 102 is connected to the telescopic rod 24 to facilitate the support of the pressure holding assembly. The pressure holding upper mold 22 is located at one end of the support plate 102, and the telescopic rod 24 is located on the inner side wall of the support plate 102.

[0032] Specifically, the support plate 102 is mainly used to support the pressure holding assembly, preventing it from shaking and improving its practicality.

[0033] By employing a pressure-holding cylinder 21 as the core pressure-applying element, replacing the traditional manually adjusted rigid clamps or bolt fixing methods, automated and precise pressure control can be achieved. Through the linear output characteristics of the cylinder, the uniform pressure required for coil winding, curing, or assembly can be stably maintained, avoiding problems such as loosening and deformation due to insufficient pressure or insulation damage and conductor displacement caused by excessive pressure. This significantly improves the precision and structural stability of coil manufacturing, ensuring equipment performance and lifespan.
