Description

Technical Field

[0001] The utility model belongs to the field of flat copper wire forming equipment, in particular to an adjusting mechanism for bending a hairpin flat copper wire. Background Art

[0002] The operating process of the flat copper wire forming equipment is as follows: the flat copper wire passes through the cleaning and detection component, and the peeling status of the surface of the flat copper wire is detected. The flat copper wire that passes the inspection is transported to the cutting and wiring mechanism through the wire pulling component for cutting. At this time, the wire grabbing mechanism grabs the flat copper wire and adjusts its horizontal position, and then it is transferred to the 2D forming station by the robotic arm for forming.

[0003] However, during the bending and forming process (such as when bending is performed at the 2D forming station mentioned above), when the specifications of the hairpin flat copper wire to be bent become larger and the spacing between the points where the paint is removed on the flat copper wire becomes larger, as the specifications of the flat copper wire increase, the cross-sectional area and weight of the wire may also change according to the requirements of the stator product. The original wire passing block position may not be able to effectively support the entire wire, resulting in a lack of necessary support for a certain part of the wire during the bending process, and the bending radius also changes accordingly. When the spacing between the paint removal points increases, the contact point between the wire passing block and the copper wire may no longer be aligned with the center line of the copper wire, resulting in uneven support, thereby affecting the bending effect. Therefore, the two wire passing blocks that are still in the initial position cannot provide good support for the flat copper wire. Utility Model Content

[0004] In view of the above defects, the utility model provides an adjustment mechanism for bending a hairpin flat copper wire, wherein the adjustment mechanism is installed at the linear slide rail I of the feeding and forming device;

[0005] It comprises two sets of two pads installed at the linear slide rail 1, the two pads are connected by a slide fixed on the top, and the connecting end of the slide is installed with a hinge assembly for extension and retraction;

[0006] The hinge assembly includes several hinge plates whose two ends are hinged by pins I in sequence. The intersection of the middle parts of each two hinge plates is hinged by pins II. The pins II located at both ends are hinge pins for connecting the connecting plates respectively. The two connecting plates are respectively installed on the linear slide rails II of the feeding and forming device, and a wire block is installed in the middle of the top of each connecting plate.

[0007] Furthermore, the bottom of the pad is clamped to the linear slide rail I through the installed slider I, and the bottoms of both ends of the connecting plate are clamped to the linear slide rail II through the installed slider II.

[0008] Furthermore, a fixing groove for installing the cutting and wiring mechanism in the feeding and forming device is provided on the top of the slide.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] When the specifications of the hairpin flat copper wire that needs to be bent become larger and the spacing between the paint-removing points on the flat copper wire becomes larger, the linear slide rail II can be used to drive the slide to move. At this time, the hinge assembly is transformed from a cross posture to a straight posture, thereby realizing the adjustment of the distance between the two connecting plates. By adapting the spacing between the paint-removing points on the flat copper wire, it is ensured that the new specifications can be effectively supported, thereby ensuring the bending quality and stability of the equipment.

The drawings illustrate embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0017] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "disposed" should be understood in a broad sense. For example, they may refer to fixed connection or disposition, detachable connection or disposition, or integral connection or disposition. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0018] Example

[0019] like Figure 1-2As shown, this embodiment provides an adjustment mechanism for bending hairpin flat copper wires, comprising two sets of two pads 1 mounted on a linear slide rail II18. The two pads 1 are connected by a slide 2 fixed at the top. The connecting end of the slide 2 is equipped with a hinge assembly for extension and contraction, and the top of the slide 2 is provided with a fixing groove for mounting a wire cutting mechanism 14.

[0020] The hinge assembly includes several hinge plates 3 whose two ends are hinged in turn through pins I. The intersection in the middle of each two hinge plates 3 is hinged through pin II. The pins II located at both ends are hinge pins 5 for connecting the connecting plates 4 respectively. The two connecting plates 4 are respectively installed on the linear slide rails II18 of the feeding and forming device. A wire passing block 6 for placing flat copper wire is installed in the middle of the top of each connecting plate 4.

[0021] Specifically, the bottom of the pad 1 is clamped with the linear slide rail I17 through the installed slider I, and the bottoms of both ends of the connecting plate 4 are movably connected with the linear slide rail II18 through the installed slider II. The slider I and slider II are respectively electric sliders adapted thereto.

[0022] It should be noted that if Figure 3 As shown, the flat copper wire forming equipment mainly includes a loading table 11 and a forming table 20 fixedly installed on the base 10, a cleaning and detection component 12, a wire pulling component 13 and a cutting and wiring mechanism 14 fixedly installed on the loading table 11 from left to right, and a transfer mechanism and two 2D forming stations 19 fixedly installed on the forming table 20. The operation process is: first, the flat copper wire passes through the cleaning and detection component 12, and the peeling state of the surface of the flat copper wire is detected. The flat copper wire that passes the detection is transported to the cutting and wiring mechanism 14 through the wire pulling component 13. The cutting and wiring mechanism 14 cuts the paint-skinned position on the flat copper wire and receives the cut flat copper wire. Then, the wire grabbing mechanism 15 grabs the cut flat copper wire and adjusts the horizontal position of the flat copper wire. Then, it is transferred to the 2D forming station 19 by the robotic arm 16 for forming. The adjusting mechanism is installed on the linear slide rail 117 of the loading and forming device, and the adjusting mechanism is installed on the servo electric cylinder 21 of the loading and forming device.

[0023] In the forming stage, when the specifications of the hairpin flat copper wire to be bent become larger and the spacing between the paint-skinned points of the flat copper wire becomes larger, the servo electric cylinder 21 can be used to drive the slide 2 to move, so that the hinge assembly and the wire cutting mechanism 14 slide along the linear guide rails I17 and II18 respectively. Figure 4 As shown, at this time, the hinge assembly is transformed from a cross posture to a straight posture, thereby adjusting the distance between the two connecting plates 4, thereby completing the adaptation of the distance between the paint-removed points on the flat copper wire and ensuring stable support.

[0024] It should be noted that the structure described in the present invention can be implemented in a variety of different forms and is not limited to the described embodiments. Any equivalent transformations made by ordinary technicians in this field using the contents of the description and drawings of the present invention, or directly or indirectly applied to other related technical fields, such as the loading and unloading of other items, are included in the scope of protection of the present invention.
