Flat wire twistable crossing wire protection entry head device

Abstract

This invention discloses a flat wire twisting and cross-protection wire insertion device. Its key feature is that a lower protective tooth sliding plate is fixed to an external device. The lower protective tooth sliding plate is sequentially equipped with a lower protective tooth turntable, a turntable, an upper protective tooth turntable, and an upper protective tooth sliding plate. The upper protective tooth sliding plate is fixedly connected to the protective tooth sliding plate. A front-and-back movement cylinder drives the two layers of protective teeth to move back and forth along the turntable's trajectory. After reaching the required stroke, a cross-movement cylinder and a winch structure cause the two layers of protective teeth to cross-move under the drive of the turntable. This achieves clear layering of the flat wire before twisting, precise insertion, and significantly improves the flat wire twisting yield. The insertion device of this invention has the advantages of convenient adjustment, precise and reliable operation, high insertion success rate, greatly improved automation, and reduced labor costs.

Description

Technical Field

[0001] This invention belongs to the field of electrical machinery, and particularly relates to a flat wire twisting inlet wire protection device. Background Technology

[0002] Flat wire twisting is an indispensable step in the production of flat wire motor stators. The purpose of twisting is to arrange the wires of each layer of the flat wire motor in a predetermined manner, laying the foundation for subsequent welding. Currently, twisting equipment requires manual straightening and smoothing of the wires before automatic twisting. This method has the disadvantages of increasing labor costs and not guaranteeing smooth feeding during automatic twisting, thus increasing the product defect rate and leading to increased costs. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the aforementioned technologies by providing a flat wire twisting and crossing wire guide device.

[0004] The technical solution of this invention is as follows: A lower protective tooth rotating disk, a rotating disk, an upper protective tooth rotating disk, and an upper protective tooth sliding disk are sequentially arranged on the lower protective tooth sliding disk. The upper protective tooth sliding disk is fixedly connected to the protective tooth sliding disk. Each lower protective tooth is evenly distributed in the corresponding slide rails of the lower protective tooth sliding disk and the lower protective tooth rotating disk. Each upper protective tooth is evenly distributed in the corresponding slide rails of the protective tooth rotating disk and the upper protective tooth sliding disk. Each lower and upper protective tooth is connected in series by corresponding sliding pins. Each sliding pin is arranged in the track groove of the rotating disk. A cylinder is connected... Plate 1 is fixedly connected to the lower protective tooth sliding plate. Cylinder 1 is hinged to cylinder connecting plate 1. Cylinder 1 is connected to U-shaped connector 1. U-shaped connector 1 is hinged to the turntable through pin 1. Cylinder connecting plate 2 is fixedly connected to the lower protective tooth sliding plate. Cylinder 2 is fixedly connected to cylinder connecting plate 2. U-shaped connector 2 is hinged to the upper protective tooth sliding plate through pin 2. The rotating shaft is placed in the corresponding holes of the lower and upper protective tooth sliding plates. The rotating lever passes through the rotating shaft. The rotating lever is hinged to the lower and upper protective tooth turntables respectively through a small rotating shaft. Beneficial effects Thanks to the adoption of a flat wire twisting and cross-protecting wire insertion device, the upper and lower protective teeth are extended towards the center along the track grooves between the upper and lower protective tooth sliding discs and the turntable, respectively, by cylinders one and two. When extended into position, they can swing left and right, which can effectively separate the flat wires of each layer according to the position of the twisting mold. This ensures that the stator end is smoothly inserted into the twisting mold, thereby achieving smooth stator twisting and forming, high qualification rate, good forming effect, saving labor costs, achieving full automation, and good economic efficiency.
