Description

Technical Field

[0001] This utility model relates to the field of automated manufacturing equipment technology, and in particular to a device for bending wires in conjunction with a turntable. Background Technology

[0002] In automated production in industries such as electronics and electrical appliances, multi-angle bending of flexible workpieces such as ribbon cables and wires is a crucial step in ensuring product performance and assembly accuracy. Traditional bending processes typically employ single-function bending heads, each capable of performing only one specific angle of bending. When a workpiece requires multiple bends of different shapes, it must be completed through multiple head changes or multiple steps, leading to low processing efficiency and cumulative errors due to repeated positioning and clamping. More importantly, existing bending heads often lack effective coordination with a specially designed positioning support structure on the carrier side during bending. This results in the workpiece relying solely on one side of the bending head for force application, lacking stable support and shape constraint during the forming process, leading to quality issues such as inaccurate bending angles and uneven curvature. Furthermore, due to the lack of a dedicated positioning support matching the bending head's movement, traditional devices struggle to simultaneously complete multiple bends of different positions and shapes on the workpiece in a single feed. This not only limits further improvements in processing efficiency but also increases equipment complexity and space requirements. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a device for bending cabling in conjunction with a turntable.

[0004] The technical solution of this utility model is as follows: it includes a rotary table, a carrier mounted on the rotary table, and a bending mechanism arranged along the outer periphery of the rotary table.

[0005] The bending mechanism includes a bending execution component, the end working part of which integrates a first forming part for forming a first bending part of the workpiece and a second forming part for forming a second bending part of the workpiece.

[0006] The material loading position of the carrier is provided on the side opposite to the bending execution component, with a first positioning support for positioning and forming the first bending part and a second positioning support for positioning and forming the second bending part.

[0007] The first forming part cooperates with the first positioning support part to jointly complete the forming of the first bending part, and the second forming part cooperates with the second positioning support part to jointly complete the forming of the second bending part.

[0008] A further technical solution is as follows: the first forming part is a concave arc forming surface, the radius of curvature of which is adapted to the target inner diameter of the first bending part of the workpiece; the second forming part is a protruding bending apex angle, the angle of which is adapted to the target angle of the second bending part of the workpiece.

[0009] A further technical solution is as follows: the first positioning support is a support sidewall, which forms a first positioning angle with the placement plane of the workpiece, and the angle of the first positioning angle is consistent with the target angle of the first bending part of the workpiece; the second positioning support is a support bottom, and the support bottom is connected to the support sidewall through a second positioning angle, and the contour of the second positioning angle is adapted to the target curvature of the second bending part of the workpiece.

[0010] A further technical solution is as follows: the bending mechanism further includes a bending drive unit and a support frame. The bending drive unit includes a first bending drive component fixed on the support frame and a second bending drive component installed on the drive end of the first bending drive component. The bending execution component is connected to the output end of the second bending drive component.

[0011] A further technical solution is as follows: the first bending drive component is an XY axis sliding platform; the second bending drive component is obliquely mounted on the drive end of the first bending drive component via a first fixing plate.

[0012] A further technical solution is that the bending execution component is connected to the output end of the second bending drive component through a first floating mechanism;

[0013] The first floating mechanism includes a mounting base fixedly connected to the output end of the second bending drive component, and a first elastic element that elastically connects the mounting base to the bending execution component. Under the action of the first elastic element, the bending execution component floats slightly relative to the mounting base along the bending feed direction.

[0014] A further technical solution includes a positioning mechanism, wherein a mounting frame extending toward the rotary table is fixedly provided on the support frame, and the positioning mechanism is mounted on the mounting frame.

[0015] A further technical solution is as follows: the positioning mechanism includes a positioning drive component, a carrier plate driven by the positioning drive component, and a cooperative positioning unit mounted on the carrier plate. The cooperative positioning unit includes a positioning pin, which cooperates with a positioning pin hole on the carrier.

[0016] A further technical solution is that the collaborative positioning unit also includes multiple positioning heads, each of which corresponds to a workpiece.

[0017] A further technical solution is that a second floating mechanism is provided between each of the positioning pressure heads and the bearing plate, and the second floating mechanism includes a second elastic element; the positioning pressure head is elastically connected to the bearing plate through the second elastic element, and floats slightly along the axial direction relative to the bearing plate when subjected to axial pressure.

[0018] The beneficial technical effects of this utility model are as follows: By cooperating with the working part at the end of the bending head and the carrier, two bends of the workpiece can be completed accurately and efficiently by the same bending head in one continuous process, significantly improving the efficiency and consistency of bending processing. At the same time, it avoids the cumulative errors caused by multiple positioning and mold changes, making it particularly suitable for batch bending production of precision workpieces such as wiring harnesses. The bending mechanism employs a first floating mechanism and a second floating mechanism, allowing the bending head and positioning pressure head to float slightly under pressure. This protects the surface quality of the workpiece and adaptively compensates for the fit deviation between the bending head and the carrier, achieving high quality and high stability of the workpiece during the bending process.

[0029] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0030] like Figure 1 and Figure 2 As shown, this utility model relates to a device for bending wiring in conjunction with a turntable, including a rotary turntable 100 rotatable around a rotation center, a carrier 200 mounted on the rotary turntable 100 for supporting multiple workpieces 1, and a bending mechanism 300 arranged along the outer periphery of the turntable. The bending mechanism 300 is used to bend the multiple workpieces 1 at a preset angle at a designated position.

[0031] The bending mechanism 300 includes a support frame 310, multiple sets of bending drive units spaced apart on the support frame, and bending execution components respectively installed at the drive ends of each of the bending drive units. Figure 3 Each bending drive unit includes a first bending drive component 320 fixed to a support frame 310 and a second bending drive component 330 obliquely mounted to the driving end of the first bending drive component 320 via a first fixing plate. The bending execution component is connected to the output end of the second bending drive component 330 via a second fixing plate. In this embodiment, the first bending drive component 320 adopts an XY-axis sliding platform. The XY-axis sliding platform is used to drive the bending execution component to achieve positioning along the vertical direction and the workpiece 1 direction. The second bending drive component 330, with the cooperation of the XY-axis sliding platform, realizes the precise bending action of the bending execution component.

[0032] The bending execution assembly includes a bending head 340, which is connected to a second fixed plate via a first floating mechanism 350. The first floating mechanism 350 includes a mounting base 351 fixedly connected to the second fixed plate, a first fastener passing through the mounting base 351 and threadedly connected to the sliding portion of the bending head 340, and a first elastic element 352 sleeved on the outer periphery of the first fastener. The first fastener is slidably engaged with the mounting base 351, and both ends of the first elastic element 352 abut against the mounting base 351 and the sliding portion of the bending head 340, respectively. The second fixed plate is also provided with a first linear slide rail 353 extending along the bending feed direction of the bending head 340. When the bending head 340 is subjected to bending pressure, it floats slightly along the first linear slide rail 353 via the sliding portion under the action of the first elastic element 352, thereby achieving flexible compression and adaptive compensation for positional deviation during the bending process.

[0033] like Figure 4 and Figure 5 The end working part of the bending head 340 integrates a first forming part and a second forming part. The first forming part is a concave arc forming surface 341, the radius of curvature of which is adapted to the target inner diameter of the first bending part 11 of the workpiece 1; the second forming part is a protruding bending apex angle 342, the angle of which is adapted to the target angle of the second bending part 12 of the workpiece 1.

[0034] The carrier 200 has a first positioning support and a second positioning support on the side opposite to the bending head 340 at the material loading position. The first positioning support cooperates with the first forming part to jointly complete the forming of the first bending part 11, and the second positioning support cooperates with the second forming part to jointly complete the forming of the second bending part 12. Specifically, the first positioning support is a support sidewall, which forms a first positioning angle 210 with the placement plane of the workpiece 1. The angle of the first positioning angle 210 is consistent with the target angle of the first bend of the workpiece 1 to position and form the first bending part 11. The second positioning support is a support bottom, which is transitionally connected to the support sidewall through a second positioning angle 220. The contour of the second positioning angle 220 is adapted to the target curvature of the second bending part 12 of the workpiece 1.

[0035] During the bending operation, the bending head 340 moves towards the carrier 200 under the drive of the bending drive unit. Its bending apex angle 342 first contacts the workpiece 1, squeezing the workpiece 1 along the support sidewall, causing the workpiece 1 to undergo plastic bending around the first positioning angle 210 of the support sidewall and completing the first bending. As the bending head 340 continues to move, its bending apex angle 342 gradually embeds into the gap formed by the workpiece 1 and the second positioning angle 220, causing the workpiece 1 to undergo a second bending within the second positioning angle 220, until the bending apex angle 342 abuts against the second positioning angle 220. At the same time, the concave arc forming surface 341 also abuts against the first positioning angle 210, finally completing the final shaping of the first bending part 11 and the second bending part 12.

[0036] In this embodiment, through the cooperation of the concave arc forming surface 341 with the first positioning angle 210 and the cooperation of the bending apex angle 342 with the second positioning angle 220, two different bends of workpiece 1 are accurately and efficiently completed by the same bending head 340 in one continuous process, ensuring high precision and high quality in the angle, arc and relative position of the two bends. Figure 6 .

[0037] Furthermore, such as Figure 7 and Figure 8 A positioning mechanism 400 is provided above the carrier 200. The positioning mechanism 400 includes a positioning drive 410, a support plate 420 driven by the drive, and a cooperative positioning unit mounted on the support plate 420.

[0038] The collaborative positioning unit includes two positioning pins 430 and multiple positioning pressure heads 440. The two positioning pins 430 are distributed at both ends of the bearing plate 420 along the length of the carrier 200 and cooperate with the positioning pin holes provided on the carrier 200 to achieve precise positioning of the carrier 200 at the bending station.

[0039] Each positioning head 440 corresponds to each workpiece 1. When the positioning drive 410 is activated, the bearing plate 420 drives the two positioning pins 430 to first insert into the positioning pin holes to complete the positioning of the carrier 200. Then, the positioning head 440 continues to move down with the bearing plate 420 and presses against the corresponding workpiece 1, thereby effectively preventing the workpiece 1 from shifting during the bending process.

[0040] Furthermore, a second floating mechanism 450 is provided between the positioning pressure head 440 and the support plate 420. The second floating mechanism 450 includes a second linear slide rail 451 mounted on the support plate 420, a second fastener threadedly connected to the positioning pressure head 440, and a second elastic element 452 sleeved on the outer periphery of the second fastener. The second linear slide rail 451 extends vertically, and a mounting block is fixedly provided on the support plate 420 above the positioning pressure head 440. The second fastener passes through the mounting block vertically and slides with it. The two ends of the second elastic element 452 abut against the positioning pressure head 440 and the mounting block, respectively. When the positioning pressure head 440 descends and contacts the workpiece 1, it floats slightly along the second linear slide rail 451 under the elastic force of the second elastic element 452, achieving flexible contact between the positioning pressure head 440 and the workpiece 1 and avoiding damage to the workpiece 1.

[0041] In this embodiment, the support frame 310 is fixedly provided with a mounting frame that extends toward the rotary table 100. The positioning mechanism 400 is mounted on the mounting frame so that the positioning pin 430 and the positioning pressure head 440 can face and act on the carrier 200 and the workpiece 1 on the lower turntable.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
