Description

Technical Field

[0001] The invention relates to the technical field of twisting cage production, in particular to a twisting device. Background Art

[0002] The existing wire harness machine pay-off frame is generally a static reel pay-off frame, which mainly relies on a rotating arm to drive the wire pay-off. The wire swings using centrifugal force. When the wire is clamped or arranged poorly, it is easy to cause wire breakage. In addition, there are wire passing porcelain eyes on the rotating arm, which is close to the wire reel. The wire entry angle and pay-off resistance are large, which can easily scratch the aluminum wire.

[0003] When existing cable bundlers are stranding, single wires are prone to wire breakage due to the large friction force on the stranding bow and the take-up wheel, which seriously affects the production efficiency and the quality of the stranded wires.

[0004] In addition, the distance between the two wire guide wheels needs to be precisely controlled when the cable is twisted. This is to ensure that the cable can pass through the guide wheels smoothly during the twisting process to avoid friction, jamming or damage caused by distances that are too close or too far.

[0005] Therefore, in order to solve the problems of easy wire breakage and low surface quality of the stranded wires during the cable stranding process, it is necessary to change the structure of the wire-bundling machine pay-off frame, and thus a stranding device is proposed. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings in the prior art and to propose a twisting device.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A twisting device comprises a pay-off machine body, a movable reel pay-off frame, a first wire guide wheel and a second wire guide wheel. The cable sent out from the pay-off machine body passes through the first wire guide wheel and the second wire guide wheel and is wound on the movable reel pay-off frame. The twisting device also comprises a tension gun, which is located in the middle section of the twisted cable and is used to adjust the tension in the wire strands.

[0009] The front end of the pay-off machine body is provided with an adjuster, and the adjuster is a shell with a sliding cavity inside;

[0010] The regulator is provided with a sliding block in its sliding cavity. In a preferred technical solution, the sliding block is a cylinder, the sliding block slides in the sliding cavity inside the regulator, the top surface and the bottom surface of the sliding block are respectively provided with bowl-shaped grooves, and the upper and lower bowl-shaped grooves are connected by a through groove.

[0011] The top wall and the bottom wall of the regulator are respectively embedded with movable balls. In a preferred technical solution, the top wall and the bottom wall of the regulator are respectively provided with ball-shaped cavities for the corresponding movable balls to be installed, and the cavity walls of the ball-shaped cavities are provided with arc grooves.

[0012] In a preferred technical solution, the movable ball is provided with protrusions on both sides of its spherical body, and the protrusions are respectively built into the arc grooves on the corresponding sides and slide along the arc.

[0013] The outer spherical surfaces of the upper and lower movable balls respectively extend outwardly with extension arms, the ends of the extension arms are respectively connected to the first wire guide wheel and the second wire guide wheel, the inner spherical surfaces of the upper and lower movable balls are respectively connected to inner spheres through straight columns, and the two inner spheres are slidably inserted in the center of the sliding block;

[0014] In a preferred technical solution, a counterweight is provided at the bottom of the movable ball at the bottom.

[0015] In a preferred technical solution, the upper and lower extension arms are arranged symmetrically about the central axis of the regulator.

[0016] In a preferred technical solution, the top surface and the bottom surface of the regulator are respectively provided with notches for the upper and lower extension arms to swing.

[0017] A locking mechanism is provided on the top surface of the regulator, and a sliding rod sliding in the horizontal direction is provided at the output end of the locking mechanism. An end block is provided at the front end of the sliding rod, and the lower surface of the end block is designed to be an inclined surface. An end ball is provided on the arm of the upper extension arm, and the end block pushes the end ball when it translates forward and causes the upper extension arm and the lower extension arm to rotate relative to each other.

[0018] In a preferred technical solution, the locking mechanism consists of a fixed seat, a cylinder, a movable bracket, a connecting arm, a guide cylinder and a sliding rod. The fixed seat is installed on the top surface of the regulator, and the cylinder is rotatably installed on the fixed seat through a rotating shaft. The front end of the pneumatic rod arranged at the output end of the cylinder is connected to the movable bracket.

[0019] In a preferred technical solution, the movable bracket is an L-shaped structural bracket, the lower end of the movable bracket is rotatably mounted on the top surface of the regulator, and the upper end of the movable bracket is connected to the pneumatic rod at the output end of the cylinder.

[0021] The beneficial effects of the present invention are:

[0022] 1. The improved pay-off frame of the wire bundling machine is a dynamic pay-off frame. The wire drum rotates with the wire pay-off. The tension gun is far from the wire drum, the pay-off angle is small, and all the wire porcelain eyes are replaced with guide wheels, which effectively prevents the single wire from being scratched or even broken during the bundle twisting.

[0023] 2. By replacing all the threading eyes on the pay-off frame and the lead-in frame with guide wheels, the path of the monofilament on the lead-in wheel is shortened and the friction is reduced, thereby significantly improving the production efficiency of the pay-off frame of the cable bundler and the surface quality of the stranded wire;

[0024] 3. The distance between the upper and lower wire guide wheels can be precisely adjusted and maintained fixed, so as to ensure that the cables can pass through the guide wheels smoothly, avoiding friction, jamming or damage of the cables caused by being too close or too far away, and ultimately effectively improving the production efficiency and product quality of the stranded wires;

[0025] In summary, the twisting equipment proposed in this scheme solves the problems of easy wire breakage and low surface quality of the twisted wire during the cable twisting process. During the cable twisting process, the wire drum rotates as the wire is paid off, and the pay-off angle is small, which reduces the wear of the cable during the twisting process and can improve the production efficiency of the wire harness pay-off frame and the surface quality of the twisted wire.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] In this embodiment, refer to Figure 1-4A twisting device includes a pay-off machine body 1, a movable reel pay-off frame 4, a first wire guide wheel 5 and a second wire guide wheel 6. In the prior art, the cable sent out from the pay-off machine body 1 passes through the first wire guide wheel 5 and the second wire guide wheel 6 and is wound on the movable reel pay-off frame 4. The twisting device also includes a tension gun 3, which is located in the middle section of the twisted cable and is used to adjust the tension in the wire strands.

[0033] A regulator 2 is provided at the front end of the pay-off machine body 1. The regulator 2 is a shell with a straight sliding cavity 7 inside.

[0034] The regulator 2 is provided with a sliding block 8 in its sliding cavity 7. Figure 4 As shown, the sliding block 8 is a cylinder, and the sliding block 8 slides in the sliding cavity 7 inside the regulator 2. The top surface and the bottom surface of the sliding block 8 are respectively provided with a bowl-mouth groove 81, and the upper and lower bowl-mouth grooves 81 are connected by a through groove 82.

[0035] The top wall and the bottom wall of the regulator 2 are respectively embedded with movable balls 9. Figure 4 As shown, the top wall and the bottom wall of the regulator 2 are respectively provided with ball-shaped cavities 24 for the corresponding movable balls 9 to be installed. Figure 3 It can be seen that an arc groove 16 is formed on the wall of the spherical cavity 24, and the movable ball 9 is provided with protrusions 15 on both sides of the sphere, and the protrusions 15 are respectively built into the arc groove 16 on the corresponding side and slide along the arc. The matching design of the protrusion 15 and the arc groove 16 is to limit the freedom of the movable ball 9 and ensure that the movable ball 9 can only slide in one direction.

[0036] The upper and lower movable balls 9 can slide freely in their corresponding spherical cavities 24 respectively, and the outer spherical surfaces of the upper and lower movable balls 9 extend outwardly as extension arms 10 respectively. In order to ensure that the extension arms 10 can swing back and forth smoothly, the top and bottom surfaces of the regulator 2 are respectively provided with notches 12 for the upper and lower extension arms 10 to swing.

[0037] It should be noted that a counterweight 11 is provided at the bottom of the movable ball 9, and the purpose of the counterweight 11 is to automatically restore the positions of the two extension arms 10. After the position of the extension arm 10 is deflected by the external force, when the external force is removed, the deadweight of the counterweight 11 can ensure that the extension arm 10 automatically returns to the initial position.

[0038] The inner spherical surfaces of the upper and lower movable balls 9 are respectively connected to inner spheres through straight columns, and the two inner spheres are slidably inserted in the through groove 82 reserved in the center of the sliding block 8.

[0039] In this embodiment, it should be particularly noted that the upper and lower extension arms 10 are symmetrically arranged about the central axis of the regulator 2 , and the angle between the two extension arms 10 is designed to be α.

[0040] When the upper movable ball 9 rotates, the extended arm 10 on the outer spherical surface of the movable ball 9 and the inner sphere on the inner spherical surface will swing synchronously. During the swinging process, the upper inner sphere will push the sliding block 8 to slide in the sliding cavity 7 of the regulator 2, and prompt the lower inner sphere to swing synchronously with the translation of the sliding block 8, and finally make the lower movable ball 9 rotate at the same time.

[0041] The upper extension arm 10 is forced to swing, and the lower extension arm 10 will swing synchronously, and the swing directions of the upper and lower extension arms 10 are just opposite, that is, the angle α between the two extension arms 10 will change. The ends of the upper and lower extension arms 10 are respectively connected to the first wire guide wheel 5 and the second wire guide wheel 6. When the angle α between the two extension arms 10 is relatively reduced, that is, the position between the first wire guide wheel 5 and the second wire guide wheel 6 changes, the cable is adjusted accordingly.

[0042] In this embodiment, a locking mechanism 13 is disposed on the top surface of the regulator 2 , and the structure of the locking mechanism 13 is described in detail.

[0043] As attached Figure 3 As shown, the locking mechanism 13 is composed of a fixed seat 17, a cylinder 18, a movable bracket 19, a connecting arm 20, a guide cylinder 21 and a slide rod 22, wherein:

[0044] The fixing seat 17 is installed on the top surface of the regulator 2, and the cylinder 18 is rotatably installed on the fixing seat 17 through the rotating shaft. The front end of the pneumatic rod arranged at the output end of the cylinder 18 is connected to the movable bracket 19;

[0045] The movable bracket 19 is an L-shaped structural bracket, the lower end of the movable bracket 19 is rotatably mounted on the top surface of the regulator 2, and the upper end of the movable bracket 19 is connected to the pneumatic rod at the output end of the cylinder 18;

[0046] The guide cylinder 21 is fixedly arranged on the top surface of the regulator 2, and the slide rod 22 is slidably inserted into the guide cylinder 21. The tail end of the slide rod 22 is rotatably connected to the bent part of the movable bracket 19 through the connecting arm 20;

[0047] An end block 23 is provided at the front end of the slide rod 22 , and the lower surface of the end block 23 is designed to be an inclined surface.

[0048] In the attached Figure 3In the structure shown, the upper extension arm 10 is provided with an end bead 14 on its arm rod, and when the end block 23 is translated forward, its bottom surface will push the end bead 14 and make the upper extension arm 10 and the lower extension arm 10 rotate relative to each other. Since the forward translation of the slide bar 22 is achieved by the extension of the pneumatic rod, the cylinder 18 only needs to control the stroke of the pneumatic rod according to the actual twisting specification to ensure that the upper extension arm 10 is maintained in a suitable position and its position remains unchanged, and finally the locking purpose is achieved, and the first wire guide wheel 5 and the second wire guide wheel 6 can be in a fixed position.

[0049] Finally, when the twisting work is completed, the pneumatic rod is withdrawn, and the upper and lower extension arms 10 will automatically return to the initial position due to the gravity of the counterweight block 11. At this position, the angle α between the two extension arms 10 is the maximum value. When the next twisting work is performed, the angle α is adjusted as needed.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
