Description

Technical Field

[0001] This utility model relates to the field of stator stamping technology, specifically a stator lamination positioning plate. Background Technology

[0002] In existing motor stator lamination processing, traditional positioning discs typically employ a fixed structure, meaning the laminations are punched on a fixed disc. These positioning discs generally lack precise automatic adjustment and often lack independent clamping and support mechanisms. During the punching process, the laminations, in a fixed state, rely solely on the basic clamping force of the positioning disc to ensure their positional stability. In prolonged operation or high-frequency stamping environments, this can easily lead to positioning misalignment and insecure clamping, consequently affecting the processing accuracy and the consistency of the finished product.

[0003] The existing positioning disc structure has significant drawbacks in the following aspects: First, because traditional positioning discs mostly use a single support and fixing method, different clamping devices need to be changed when positioning blanks of different specifications. This not only complicates the operation but also increases the debugging time during equipment use, reducing production efficiency. Second, traditional positioning discs lack flexible radial sliding and adjustment functions, making it difficult to adapt to blanks of various specifications during the positioning process. Furthermore, existing positioning discs typically fail to achieve precise rotation control, especially in multi-process stamping, where maintaining consistent positioning accuracy is difficult, affecting the quality of the finished product.

Structurally, the positioning plate includes a support tray, a sliding assembly, and a rotary drive assembly, enabling it to adapt to the positioning needs of various lamination specifications, improving positioning accuracy and enhancing the adaptability of the equipment.

[0005] A stator lamination positioning plate includes: a lamination tray, a positioning tray, and a worm gear rotatably mounted inside the lamination tray. The lamination tray has a drive motor inside for rotating the worm gear. The worm gear has worm gear ribs and transmission gear ribs on its upper and lower sides, respectively.

This design effectively improves positioning accuracy and ensures the stability of the stamping process.

[0006] In a preferred embodiment, the present invention can be further configured such that: the positioning tray is fan-shaped, and several positioning trays are evenly distributed in the circumferential direction; the support rails and slides correspond one-to-one with the positioning trays and are arranged in the radial direction.

[0007] By adopting the above technical solution, the design enables multiple positioning trays to be evenly distributed circumferentially on the surface of the positioning plate, achieving multi-point support, ensuring stability during the stamping positioning process, and improving the reliability of the stamping process.

[0009] By adopting the above technical solution and through the concentric arrangement design of the adjusting groove and the sliding nut, the positioning of the positioning tray at different radii can be flexibly adjusted, realizing the universal positioning of multiple specifications of punches and enhancing the applicability of the equipment.

[0010] In a preferred embodiment, the present invention can be further configured such that: the top surface of the sliding block is provided with a slide rail adapted to the slide groove, and the support rail is slidably installed between the slide groove and the positioning tray.

[0011] By adopting the above technical solution, a slide rail is set on the top surface of the slide block, and a sliding groove is used to guide the sliding of the support rail, thereby enhancing the support force during the stamping positioning process and improving the stability of positioning and clamping.

[0012] In a preferred embodiment, the present invention can be further configured such that the spiral rib is in the shape of a planar spiral, and the bottom end of the sliding block engages with the surface of the spiral rib.

[0013] By adopting the above technical solution, the planar spiral ribs are used to achieve precise sliding control of the sliding block, effectively improving the radial adjustment accuracy of the punch during the positioning process and ensuring the accuracy of the positioning effect.

[0014] In a preferred embodiment, the present invention can be further configured such that the drive motor is a geared motor structure and the output end is provided with a keyed shaft that meshes with the transmission tooth ridge.

[0015] By adopting the above technical solution, using a geared motor drive and transmission gears for rotation control, the rotation of the positioning disc is ensured to be slow and stable, effectively improving positioning accuracy.

[0016] In a preferred embodiment, the present invention can be further configured such that: the clamping ear is arranged vertically to the surface of the positioning tray, and the surface of the clamping ear is provided with a slot for positioning the stator lamination.

[0018] The beneficial effects achieved by this utility model are as follows:

[0019] 1. In this utility model, by combining a lamination tray, a positioning tray, and a worm gear structure, the precise rotation control of the stator lamination positioning disc is achieved by using a drive motor to drive the worm gear ribs and transmission teeth within the worm gear.

[0020] 2. In this utility model, the positioning tray and sliding block are supported by a support rail and a sliding groove, respectively, which improves the support force on the stator laminations. Combined with the threaded adaptation of the adjusting groove and the sliding nut, the positioning function of the stator laminations at different radii is achieved.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0029] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0030] The following is in conjunction with the appendix Figures 1-5 This invention describes a stator lamination positioning plate provided by some embodiments of the present invention. Example 1

[0031] In this embodiment, the present invention is used for precise positioning of stator laminations in a motor. The stator lamination positioning disc includes a lamination tray 100, a positioning tray 200, and a worm gear 300. The lamination tray 100 serves as a base, used to mount and support the entire positioning structure. The worm gear 300 is rotatably mounted inside the lamination tray 100, and its rotation is controlled by a drive motor 310. The drive motor 310 is a geared motor, capable of smoothly controlling the rotation of the worm gear 300. The upper and lower sides of the worm gear 300 are respectively provided with helical rack and pinion ribs 301 and planar rack and pinion drive ribs 302, for meshing with radial sliding components, thereby providing precise drive during stator lamination positioning.

[0032] The positioning tray 200 is a component for clamping and positioning, and is fan-shaped. Multiple positioning trays 200 are evenly distributed around the circumference of the lamination tray 100. A sliding block 230 is fixedly connected to the bottom surface of each positioning tray 200, and the bottom end of the sliding block 230 engages with the worm gear 301. When the drive motor 310 drives the worm gear 300 to rotate, the engagement between the worm gear 301 and the sliding block 230 causes the positioning tray 200 to slide radially, thereby achieving precise positioning of the stator laminations.

[0033] In addition, the lamination tray 100 is provided with radial slide rails 110 and slide grooves 120 on its surface to support and guide the radial movement of the positioning tray 200, ensuring that the positioning tray 200 remains stable during sliding. For ease of operation, concentrically arranged adjustment grooves 220 are provided on the surface of the positioning tray 200, and threaded adapter sliding nut 221 is slidably installed on its inner side. The radial position of the positioning tray 200 can be changed by adjusting the clamping lugs 210 to adapt to stator laminations of different specifications, thus enhancing the versatility of the positioning tray. Example 2

[0034] In this embodiment, the structure of the stator lamination positioning disk of this utility model is similar to that of Embodiment 1, but it further adds a variety of adjustment and support functions to adapt to the stator lamination positioning requirements under different working conditions.

[0035] The lamination tray 100 is the main support tray, on which several slide rails 110 are fixedly installed to guide the sliding of the positioning tray 200. The positioning tray 200 has a fan-shaped design, with multiple positioning trays 200 evenly distributed along the circumference of the lamination tray 100, so that each positioning tray 200 can slide independently and clamp stator laminations of different specifications, thus improving the versatility of the positioning tray.

[0036] An arc-shaped adjustment groove 220 is provided on the inner side of the positioning tray 200, and a threaded slider nut 221 is provided, which can assemble the clamping lug 210 at different radius positions to meet the radial positioning requirements of the stator lamination. The sliding block 230 is a sliding block with a slide rail on its bottom surface, which is used to slide and install inside the slide groove 120 to achieve radial support and guidance of the positioning tray 200. At the same time, the sliding block 230 and the spiral rib 301 have a planar spiral meshing structure design. When the positioning plate rotates, the sliding block 230 achieves precise radial movement of the stator lamination through the meshing movement with the spiral rib 301.

[0037] To achieve precise rotation control, the output end of the drive motor 310 is equipped with a keyed shaft that meshes with the transmission gear 302, enabling the drive disc to rotate slowly. This allows for precise positioning and support of the laminations on each positioning tray 200. Controlled by the drive motor 310, the worm gear 300 rotates, causing the positioning trays 200 to slide and clamp evenly along the radial direction, thus improving stability during the positioning process.

[0038] Detailed instructions

[0039] In practical use, the operator first selects the appropriate positions of the adjusting groove 220 and the sliding nut 221 according to the size and specifications of the stator laminations, and positions the clamping lug 210 with the lamination slot. The drive motor 310 is then started, causing the worm gear 300 to rotate slowly. Through the worm gear ribs 301 and the transmission gear ribs 302, the sliding block 230 slides radially, simultaneously positioning and clamping the stator laminations on multiple positioning trays 200. After the laminations are positioned, the positioning trays 200 are supported by the support rails 110 and the sliding grooves 120 to maintain the clamped state, ensuring the stability and accuracy of the laminations during the positioning process.

[0040] This utility model's multifunctional positioning structure, through its combined structural design and multiple control mechanisms, achieves efficient positioning and clamping of stator laminations of different specifications.
