Description

Technical Field

[0001] This invention relates to an adjustable core stacking auxiliary tool. Background Technology

[0002] In existing technologies, the core process hole structure is generally located in the middle of the yoke and the column. While this position facilitates lamination and allows for direct positioning by the locating pin, it also increases core losses to some extent, especially for low-capacity cores. Iron loss tests have shown that edge holes reduce losses to some extent compared to conventional holes under high magnetic flux density. Therefore, it is considered to reduce losses by modifying the core process hole structure. However, the current technology lacks a dedicated half-hole positioning lamination fixture, resulting in low lamination efficiency for workers and making it difficult to meet the needs of mass production.

[0003] CN205298190U discloses an automatic lifting and positioning pin for stacking a full series of iron cores. It requires adjusting the height of the positioning pin by adjusting the lifting mechanism driven by the motor to complete the stacking of iron cores with different thicknesses and process hole sizes. Each positioning pin needs to be adjusted individually during stacking, which is cumbersome and cannot effectively improve the stacking efficiency. Summary of the Invention

[0004] This invention proposes an adjustable core stacking auxiliary tool, which aims to overcome the aforementioned shortcomings of existing technologies, thereby reducing core loss and improving stacking efficiency.

[0005] The technical solution of this invention: An adjustable core stacking auxiliary tool, comprising a base with a vertical column, a diagonal beam connected to the top of the column, and a horizontally arranged upper and lower crossbeam slidably connected to the column. A fixed pulley A is located at the highest point of the diagonal beam, and a fixed pulley B is located at the connection between the column and the diagonal beam. A suspension line for the upper crossbeam, passing through the fixed pulley B, is wound around the fixed pulley A. The end of the suspension line extends downwards to near the upper crossbeam and connects to the upper crossbeam hook. A semi-circular pull ring matching the shape of the upper crossbeam hook is located at the end of the upper crossbeam. The upper crossbeam hook engaging the semi-circular pull ring stabilizes the position of the upper crossbeam and constrains the upper positioning posts. Several horizontally adjustable upper positioning posts are arranged along the length of the upper crossbeam, allowing simultaneous positioning of different... The upper crossbeam features a wide silicon steel sheet with a horizontal scale along its length, allowing for quantified positioning and improved accuracy. The upper positioning post is connected to the upper crossbeam via a telescopic sleeve to prevent rotation. The lower crossbeam has horizontally adjustable lower positioning posts corresponding to the number of upper positioning posts along its length, and also features a horizontal scale along its length. The bottom of each lower positioning post is connected to the lower crossbeam via a telescopic spring sleeve, which is equipped with a spring adjustment assembly to accommodate stacking requirements of different sheet widths and heights. The base below the lower crossbeam has a horizontally adjustable support height adjuster, which houses the lower crossbeam support, meeting the stacking requirements of products with different specifications.

[0006] The advantages of this invention are: a reasonable structural design, which allows for synchronous constraint of different lamination widths through the design of multiple positioning columns at the top and bottom; the horizontal scale on the crossbeam quantifies the lamination accuracy, which not only meets the needs of laminating half-hole cores, but also greatly improves the positioning accuracy of the lamination process. All lamination widths are positioned, which can prevent lamination personnel from unknowingly affecting the previously laminationd parts when laminating other lamination widths, thus affecting the lamination quality; it can improve the efficiency of personnel lamination; and the investment cost is low, making it highly practical.

Detailed Implementation

[0014] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0015] like Figure 1-6 As shown, an adjustable core stacking auxiliary tool includes a base 16 with a vertical column 18 on it. One end of a diagonal beam 19 is connected to the top of the column 18. A horizontally arranged upper beam 3 and lower beam 6 are slidably connected to the column 18. Specifically, a beam height adjustment slide rail 15 is provided along the length of the outer side of the column 18. The upper beam 3 and lower beam 6 are respectively sleeved on the column 18, and their end sliders are slidably connected to the beam height adjustment slide rail 15. A fixed pulley A 1 is provided at the highest point of the diagonal beam 19, and a fixed pulley B 2 is provided at the connection between the column 18 and the diagonal beam 19. An upper beam suspension line 9, passing through the fixed pulley B 2, is wound around the fixed pulley A 1. The end of the upper beam suspension line 9 extends downwards to near the upper beam 3 and connects to the upper beam hook 10. A semi-circular pull ring matching the shape of the upper beam hook 10 is provided at the end of the upper beam 3. A horizontally arranged upper beam hook 10 is provided along the length of the upper beam 3. There are several horizontally adjustable upper positioning posts 4, and a horizontal scale 17 is also provided along the length of the upper crossbeam 3. The upper positioning posts 4 are specifically connected to the upper crossbeam 3 through upper positioning post telescopic sleeves 5. The upper positioning post telescopic sleeves 5 specifically include a sleeve fixed on the upper crossbeam 3 and a positioning screw set in the middle of the sleeve. The upper positioning posts 4 pass through the sleeve. The lower crossbeam 6 is provided with horizontally adjustable lower positioning posts 7 along the length of the lower crossbeam 6, corresponding to the number of upper positioning posts 4. A horizontal scale 17 is also provided along the length of the lower crossbeam 6. The bottom end of the lower positioning posts 7 is connected to the lower crossbeam 6 through a lower positioning post telescopic spring sleeve 8. A spring adjustment assembly 14 is installed on the lower positioning post telescopic spring sleeve 8. A horizontally adjustable support platform height adjuster 12 is provided on the base 16 below the lower crossbeam 6. The support platform height adjuster 12 is equipped with a lower crossbeam support platform 11. A transport groove 13 is also opened on the base 16.

[0016] The upper crossbeam 3 is used to mount the upper positioning column 4 and is equipped with a horizontal scale 17, which can quantify the positioning and improve the positioning accuracy.

[0017] The upper positioning post 4 is designed for the semi-hole structure and can simultaneously position silicon steel sheets of different widths.

[0018] The upper positioning post telescopic sleeve 5 is used to constrain the upper positioning post 4 and prevent it from rotating.

[0019] The lower crossbeam 6 is used to support the lower positioning column 7 and is also equipped with a horizontal scale 17, which can quantify the positioning and improve the positioning accuracy.

[0020] The lower positioning post 7 is used to constrain and position the half-hole structure.

[0021] The lower positioning post telescopic spring sleeve 8 provides space for placing the spring. The side is provided with a serrated structure. By changing the position of the spring sleeve at different heights of the serrations, the amount of spring extension can be adjusted, thereby controlling the height of the positioning post and achieving the requirement of constraining stacked pieces of different widths and heights.

[0022] The upper beam suspension line 9 is used to connect fixed pulley A 1, fixed pulley B 2 and upper beam hook 10.

[0023] The upper beam hook 10 is used to stabilize the position of the upper beam 3 and constrain the upper positioning column 4 by hooking the semi-circular pull ring on the right side of the upper beam 3.

[0024] The lower crossbeam support 11 is used to support the lower crossbeam 6, stabilize the position of the lower crossbeam 6, and constrain the lower positioning column 7.

[0025] The support height adjuster 12 includes a slider that is slidably connected to a track on the base 16, and a telescopic rod that connects to the slider. The lower crossbeam support 11 is installed at the top of the telescopic rod. The height of the lower crossbeam support 11 is adjusted by the movement of the slider on the track and the extension and retraction of the telescopic rod to meet the stacking requirements of products of different specifications.

[0026] The transport chute 13 is used for the safe handling of the equipment by personnel.

[0027] Based on the above structure, when starting the lamination, adjust the platform height adjuster 12 and the lower crossbeam 6 to the appropriate lamination position. After placing the reference piece, the lamination personnel fine-tune the lower positioning post 7 to the half-hole of the silicon steel sheet. Adjust the position of the spring sleeve at the position of the lower positioning post telescopic spring sleeve 8 until the height of the lower positioning post 7 is appropriate. Then, the lamination personnel proceed with the lamination. After laminating one level, adjust the position of the next lower positioning post 7 and repeat the above steps. Note that when laminating to the main level and beyond, the upper crossbeam 3 is involved. Adjust the constraint position of the upper positioning post 4 according to the sheet width. After confirming the lateral distance of the positioning post, adjust the length of the upper crossbeam hook 10 to pull the semi-circular pull ring on the right side of the upper crossbeam 3, thereby improving the stability of the upper crossbeam 3. Then, adjust the vertical height of the upper positioning post 4 by turning the screw on the upper positioning post telescopic sleeve 5. After reaching the appropriate position, the personnel proceed with the lamination. The subsequent lamination of sheet widths is repeated in the same cycle.

[0028] All of the components described above are existing technologies, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0029] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
