Technical Field

[0001] The invention relates to the technical field of cable stranding, in particular to a point winding device for a stranding machine. Background Art

[0002] Wire twisting machine is a kind of mechanical equipment that can be widely used in twisting various soft / hard conductor wires, so that multiple single conductors are twisted into one strand to meet the process requirements of wire materials. Wire twisting machines can generally be divided into single twisting machines, pair twisting machines, high-speed twisting machines, back-twisting machines, cage twisting machines, frame twisting machines, tubular twisting machines and disc twisting machines according to the twisting method. In the cable processing process, after the wire twisting machine completes the twisting, it is necessary to perform point winding on the cable surface. The so-called point winding is to intermittently wrap some tape on the outer surface of the cable.

[0003] The existing twisting machines generally have automatic spot winding devices, which automatically perform spot winding on both ends of the cables after twisting them. The twisting steps are generally: cable loading, twisting, spot winding, and unloading. A twisting machine can only twist a single cable, resulting in low overall twisting and spot winding efficiency. In order to improve the overall working efficiency of the twisting machine in the prior art, multiple twisting devices and spot winding devices are usually set, which not only occupy a large space, but also need to be equipped with corresponding power components to drive the twisting device.

[0014] It can be seen from the above technical solutions that the point winding device for a stranding machine provided in the embodiment of this specification has at least the following beneficial effects:

[0015] (1) The present invention drives the fixed clamping head and the movable clamping head to rotate through a rotating device. The movable clamping head realizes the effect of automatically twisting the cables through the meshing of the meshing gear and the spiral gear seat. The distance between the movable clamping head and the fixed clamping head is controlled by the distance adjusting device to realize adaptive twisting of the cables. Multiple groups of fixed clamping heads and movable clamping heads are arranged in a circular array to achieve the effect of working on multiple groups of cables. The space is small and the point winding of the twisted cables is achieved during the loading and unloading of the cables. The cables are automatically twisted during the operation and replacement of the cables, so that the working time of the cables is fully utilized to achieve the effect of efficiently twisting and point winding the cables. At the same time, there is no need to set up multiple groups of driving components to realize the automatic twisting of multiple groups of cables.

[0016] (2) The present invention achieves the effect of lateral movement of the sliding shaft during the rotation of the sliding air block as a whole through the distance adjustment device. The connecting seat slides the sliding shaft on the sliding air block in the spiral groove, and the movable clamping head as a whole gradually approaches the fixed clamping head along the spiral groove according to the angle of revolution, thereby achieving the effect of automatic adaptation of the cable clamping distance of the movable clamping head according to the degree of cable twisting. The shapes of the spiral tooth seat and the spiral groove correspond to each other, thereby achieving the purpose of adaptive meshing of the meshing gear with the spiral tooth seat during the movement of the connecting seat.

[0017] (3) The present invention sets a total hydraulic chamber to elastically control the positions of the four sliding air blocks. The four sliding air blocks are always squeezed by the spring force on the inner hydraulic block and the plug plate in the total hydraulic chamber. Once the upper sliding shaft of one of the sliding air blocks moves to the rectangular groove, the sliding air block will be affected by the elastic hydraulic pressure and quickly extend from the inner hydraulic block, thereby driving the movable clamping head at that location away from the fixed clamping head. The position of the rectangular groove corresponds to the position of the loading area, so that the movable clamping head continues to rotate after loading and gradually approaches the fixed clamping head to achieve the effect of self-adaptation of the cable stranding pressure.

[0018] (4) The present invention achieves the effect of double magnetic limiting of clamping plate 1 and clamping plate 2 by setting a central magnet, side magnet 1 and side magnet 2. On the one hand, clamping plate 1 and clamping plate 2 can be stably clamped without being driven by hard external force. On the other hand, clamping plate 1 and clamping plate 2 can use magnetic force to move and reset after being driven by hard external force, thereby achieving automatic clamping of clamping plate 1 and clamping plate 2.

[0019] (5) The present invention drives the driving shaft on the driving wheel through an active motor to drive the automatic extrusion device and the intermittent groove wheel to move in turn. The intermittent groove wheel drives the fixed clamping head and the movable clamping head to rotate. The movable clamping head twists the wire by self-rotation through the meshing gear and the spiral gear seat. During the intermittent groove wheel is stopped, the automatic point winding device automatically point winds the cables in the unloading area, the automatic extrusion device realizes automatic unloading of the point-wound cables, and the automatic clamping work of the cables in the loading area. During the unloading and unloading of the cables, the cables are point wound after being twisted, and the cables are automatically twisted during the operation and replacement of the cables, so as to make full use of the working time of the cables and achieve the effect of efficient twisting and point winding of the cables.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1 - Fig.15As shown, a point winding device for a stranding machine comprises a stranding machine base 1, on which an automatic point winding device 2 is installed; a rotating device 3, which is arranged on one side of the stranding machine base 1, and on which a fixed seat 4 is arranged, on which four fixed clamping heads 5 distributed in a circular array are fixedly connected, and one end of the fixed seat 4 away from the rotating device 3 is fixedly connected to a distance adjusting device 7 through a coupling rod 6, and on which the distance adjusting device 7 are provided movable clamping heads 8 distributed in a circular array and having the same number as the fixed clamping heads 5. Four groups of symmetrically distributed fixed clamping heads 5 and movable clamping heads 8 are used to clamp and position the two ends of the four groups of cables. The movable clamping head 8 is fixedly connected to a meshing gear 9; a connecting base 10, which is fixedly connected to the side of the stranding machine base 1 away from the rotating device 3, and a spiral gear seat 11 is fixedly connected to the connecting base 10; an automatic squeezing device 12, which is arranged on the stranding machine base 1, and is used to control the fixed clamping head 5 and the movable clamping head 8 in the corresponding position to automatically open. The internal structure of the fixed clamping head 5 is the same as that of the movable clamping head 8. The surface of the meshing gear 9 meshes with the inner wall of the spiral gear seat 11. The rotating device 3 drives the four fixed clamping heads 5 on the fixed seat 4 to rotate synchronously with the distance adjusting device 7 on the coupling rod 6. The distance adjusting device 7 drives the four movable clamping heads 8 thereon to rotate. The movable clamping head 8 rotates by intermittently meshing with the meshing gear 9 and the spiral gear seat 11 during the revolution with the fixed clamping head 5. The fixed clamping head 5 drives one end of the cable to rotate and twist the cable, thereby realizing the effect of automatically twisting the cable. During the automatic twisting period, The distance adjusting device 7 controls the movable clamping head 8 to automatically adapt to the distance from the fixed clamping head 5 according to the degree of cable twisting, and arranges multiple groups of fixed clamping heads 5 and movable clamping heads 8 in a circular array to achieve the effect of twisting and point winding multiple groups of cables in sequence, which occupies a small space and can realize point winding of the twisted cables during cable loading and unloading, and automatic twisting during cable operation and replacement, making full use of the working time of the cables to achieve the effect of efficient twisting and point winding of the cables. At the same time, there is no need to set up multiple groups of driving components to realize the automatic twisting of multiple groups of cables.

[0039] In this embodiment, the distance adjusting device 7 includes a main hydraulic tank 71, one end of which is fixedly connected to the end of the coupling rod 6, and the interior of the main hydraulic tank 71 is elastically connected to a plug plate 72 through a spring, and the surface of the plug plate 72 is piston-connected to the inner wall of the main hydraulic tank 71, and the end of the main hydraulic tank 71 away from the coupling rod 6 is fixedly connected to a limited shaft seat 73, and the limited shaft seat 73 is provided with limiting slide grooves 74 with the same number as the movable clamping head 8 and distributed in a circular array, and the interiors of the four limiting slide grooves 74 are all slidably connected to sliding gas blocks 75, and the interiors of the four sliding gas blocks 75 close to the main hydraulic tank 71 are all piston-connected to internal hydraulic blocks 76. The interiors of the warehouse 71, the internal hydraulic block 76 and the sliding air block 75 are all filled with sealing liquid. The end of the internal hydraulic block 76 is fixedly connected to the total hydraulic warehouse 71, and the interior of the internal hydraulic block 76 is communicated with the interior of the total hydraulic warehouse 71. The sliding air block 75 is respectively fixedly connected with a sliding shaft 77 and a connecting seat 78. The movable clamping head 8 is rotatably connected to the connecting seat 78. The end of the limiting shaft seat 73 away from the total hydraulic warehouse 71 is rotatably connected to a distance adjusting base 79. The end of the distance adjusting base 79 away from the limiting shaft seat 73 is fixedly connected to the stranding machine base 1. The distance adjusting base 79 is provided with a distance adjusting groove 710. The end of the sliding shaft 77 is slidably connected in the distance adjusting groove 710. Figure 4 As shown, the pitch-adjusting groove 710 is composed of a spiral groove and a rectangular groove. By setting the spiral groove, the sliding shaft 77 can move laterally while the sliding air block 75 rotates as a whole. The connecting seat 78 slides in the spiral groove through the sliding shaft 77 on the sliding air block 75. The movable clamping head 8 as a whole gradually approaches the fixed clamping head 5 along the spiral groove according to the angle of revolution, thereby achieving the effect that the clamping distance of the cable by the movable clamping head 8 automatically adapts according to the degree of cable twisting. The shape of the spiral tooth seat 11 corresponds to that of the spiral groove, thereby achieving the purpose of adaptive meshing of the meshing gear 9 with the spiral tooth seat 11 while the connecting seat 78 moves.

[0040] The four sliding air blocks 75 are always squeezed by the spring force on the internal hydraulic block 76 and the plug plate 72 inside the main hydraulic chamber 71. Once the sliding shaft 77 on one of the sliding air blocks 75 moves to the rectangular groove, the sliding air block 75 will be affected by the elastic hydraulic pressure and quickly extend from the internal hydraulic block 76, thereby driving the movable clamping head 8 at this location away from the fixed clamping head 5. The position of the rectangular groove corresponds to the position of the loading area, so that the movable clamping head 8 continues to rotate after loading, and gradually approaches the fixed clamping head 5 to achieve the effect of self-adaptation of the cable stranding pressure.

[0041] Furthermore, the movable clamping head 8 includes a clamping seat 81, such as Figure 5As shown, one side of the clamp seat 81 is fixedly connected to the meshing gear 9 through a shaft, and the clamp seat 81 is rotatably connected to the connecting seat 78 through the shaft. The interior of the clamp seat 81 is slidably connected to a symmetrically distributed clamp plate 1 82 and a clamp plate 2 83, and a guide shaft rod 84 is fixedly connected to the clamp plate 1 82 and the clamp plate 2 83. Figure 6 As shown, the end of the guide shaft rod 84 is slidably connected with an inclined groove guide seat 85, and the inclined groove guide seat 85 is slidably connected to the inside of the clamp seat 81. The position of the inclined groove guide seat 85 in the clamp seat 81 can control the distance between the first clamp plate 82 and the second clamp plate 83. When the inclined groove guide seat 85 is retracted in the clamp seat 81, the first clamp plate 82 and the second clamp plate 83 are in a separated state. When the inclined groove guide seat 85 is extended out of the clamp seat 81, the first clamp plate 82 and the second clamp plate 83 are in a merged state. The clamp seat 81 is respectively fixedly connected with a center magnet 86, a side magnet 1 87 and a side magnet 2 88. The two ends of the center magnet 86 generate magnetic attraction with the surfaces of the first clamp plate 82 and the second clamp plate 83 respectively, the surface of the side magnet 1 87 generates magnetic repulsion with the surface of the first clamp plate 82, and the surface of the side magnet 2 88 generates magnetic repulsion with the surface of the second clamp plate 83. The fixed clamping head 5 also includes a clamping seat 81, a clamping plate 1 82 and a clamping plate 2 83, a guide shaft rod 84, and an inclined groove guide seat 85. The internal structure connection method is the same as that of the movable clamping head 8. The fixed clamping head 5 is in a fixed state as a whole, and the movable clamping head 8 can rotate as a whole. By setting a central magnet 86, a side magnet 1 87 and a side magnet 2 88, the clamping plate 1 82 and the clamping plate 2 83 can be double-magnetically limited. On the one hand, the clamping plate 1 82 and the clamping plate 2 83 can be fixed without being subjected to a hard external force. On the one hand, it can perform stable clamping when driven, and on the other hand, it can make the clamp plate 1 82 and the clamp plate 2 83 use magnetic force to move and reset after being driven by a hard external force, so as to achieve the automatic clamping of the clamp plate 1 82 and the clamp plate 2 83. Because the clamp seat 81 on the movable clamping head 8 will revolve and rotate as a whole after clamping the cable, the magnetic force positioning the clamp plate 1 82 and the clamp plate 2 83 is greater than the sum of the centrifugal force and the resistance of the stranded wire during the overall rotation of the clamp seat 81, thereby ensuring the stable clamping of the clamp plate 1 82 and the clamp plate 2 83.

[0042] Furthermore, the rotating device 3 includes a driving motor 31 and an intermittent groove wheel 34 fixedly mounted on the fixed seat 4. The end of the driving motor 31 is fixedly mounted on the stranding machine base 1. The output shaft of the driving motor 31 is clamped with a driving wheel 32. The driving wheel 32 is fixedly connected with a driving shaft 33. The driving motor 31 drives the automatic extrusion device 12 and the intermittent groove wheel 34 to move through the driving shaft 33 while driving the driving wheel 32 to rotate one circle. The intermittent groove wheel 34 drives the four fixed clamping heads 5 on the fixed seat 4 to rotate synchronously with the distance adjusting device 7 on the coupling rod 6. The distance adjusting device 7 drives the four movable clamping heads 8 thereon to rotate. The movable clamping heads 8 rotate synchronously with the fixed seat 4. During the revolution of the fixed clamping head 5, the meshing gear 9 and the spiral gear seat 11 are intermittently engaged to rotate, and one end of the cable is driven by the fixed clamping head 5 to rotate and twist the wire, thereby achieving the effect of automatically twisting the cable. During the pause of the intermittent groove wheel 34, the automatic point winding device 2 automatically point winds the cables in the unloading area, and the automatic extrusion device 12 realizes automatic unloading of the point-wound cables, and automatically clamps the cables in the loading area. During the unloading and unloading of the cables, the twisted cables are point wound, and the cables are automatically twisted during the operation and replacement of the cables, so as to make full use of the working time of the cables and achieve the effect of efficient twisting and point winding of the cables.

[0043] In addition, the automatic extrusion device 12 includes a hydraulically controlled base 121, the bottom end of which is fixedly connected to the stranding machine base 1, the interior of the hydraulically controlled base 121 is elastically connected to a hydraulic rod 122 through a spring, a passive pressure wheel 123 is fixedly connected to the hydraulic rod 122, a connecting base 124 is fixedly connected to the hydraulically controlled base 121, and four hydraulic heads 125 are connected to the pistons on the connecting base 124. The hydraulically controlled base 121, the connecting base 124 and the four hydraulic heads 125 are all filled with sealing liquid, so as to achieve the effect of controlling the height of the hydraulic rod 122 to perform hydraulic work on the four hydraulic heads 125. The four hydraulic heads 125 correspond to the fixed clamping heads 5 and the movable clamping heads 8 in the loading and unloading areas, respectively, and are used to extrude the fixed clamping heads 5 and the movable clamping heads 8 in the loading and unloading areas (such as Figure 1 As shown in the figure, the fixed clamping head 5 and the inclined groove guide seat 85 in the movable clamping head 8 in this area are squeezed and restricted by the hydraulic head 125, and are in a contracted state in the clamping seat 81. At this time, the inclined groove guide seat 85 drives the clamping plate 1 82 and the clamping plate 2 83 to work separately through the two guide shafts 84, so as to facilitate the loading and unloading of cables between the clamping plate 1 82 and the clamping plate 2 83 in the fixed clamping head 5 and the movable clamping head 8. In the initial state, the driving shaft 33 is squeezed on the passive pressure wheel 123 (as shown in the figure). Figure 7As shown in the figure, at this time, the hydraulic rod 122 always squeezes the liquid in the hydraulic control base 121, and the four hydraulic heads 125 in the connecting base 124 are driven to extend out of the connecting base 124 through the squeezed hydraulic pressure, thereby achieving the effect of synchronously squeezing the inclined groove guide seat 85 in the fixed clamping head 5 and the movable clamping head 8, and the surface of the driving shaft 33 contacts the surface of the passive pressure wheel 123, and the hydraulic head 125 is used to squeeze the inclined groove guide seat 85 to drive the clamping plate 1 82 and the clamping plate 2 83 to separate.

[0044] When the point winding device of the stranding machine of the present invention is in use, the cable is fed from one side of the stranding machine base 1 to between the fixed clamping head 5 and the movable clamping head 8 through the feeding mechanism, and the hydraulic head 125 there squeezes the inclined groove guide seat 85, and the inclined groove guide seat 85 is in a contracted state in the clamping seat 81, and the inclined groove guide seat 85 drives the clamping plate 1 82 and the clamping plate 2 83 to work separately through two guide shaft rods 84, that is, the fixed clamping head 5 in the feeding area and the clamping plate 1 82 and the clamping plate 2 83 on the movable clamping head 8 are in an open state (such as Figure 1As shown in the figure, after the cable is loaded, the active motor 31 is started, and the output shaft of the active motor 31 is rotated by the driving shaft 33 on the active wheel 32. Before the driving shaft 33 contacts the intermittent groove wheel 34, the passive pressure wheel 123 loses the squeezing of the driving shaft 33 at the top, and uses the spring on the hydraulic rod 122 to realize upward movement and reset. During the reset period, after the hydraulic rod 122 extends out of the hydraulic control base 121 by elastic force, the four hydraulic heads 125 in the connecting base 124 are synchronously contracted into the connecting base 124 by the influence of negative pressure, that is, the four hydraulic heads 125 are simultaneously away from the inclined groove guide seat 85 in the fixed clamping head 5 and the movable clamping head 8. After the inclined groove guide seat 85 loses the squeezing restriction, the fixed clamping head 5 and the clamping plate 1 82 and the clamping plate 2 83 in the movable clamping head 8 are merged by the influence of magnetic force, and the automatic clamping of the cable is realized after the merger. After the driving shaft 33 contacts the intermittent groove wheel 34, it drives the intermittent groove wheel 34 to rotate ninety degrees. The intermittent groove wheel 34 drives the distance adjustment device 7 on the coupling rod 6 and the four movable clamping heads 8 to rotate synchronously through the fixed seat 4. During the rotation, the four fixed clamping heads 5 and the movable clamping heads 8 are replaced in position. The fixed clamping heads 5 and the movable clamping heads 8 that were originally in the unloading area rotate to the loading area. After rotating ninety degrees, the continuously rotating active wheel 32 squeezes the passive pressure wheel 123 again through the driving shaft 33. The passive pressure wheel 123 applies pressure to the liquid in the hydraulic control base 121 through the hydraulic rod 122, and uses the hydraulic pressure to drive the four hydraulic heads 125 respectively. It extends out of the connecting base 124, and again realizes the effect of synchronously squeezing the fixed clamping head 5 and the inclined groove guide seat 85 in the movable clamping head 8 in the loading area, so as to facilitate the fixed clamping head 5 and the movable clamping head 8 to load cables there. Similarly, the hydraulic head 125 in the unloading area squeezes the fixed clamping head 5 and the inclined groove guide seat 85 in the movable clamping head 8, so that the fixed clamping head 5 and the movable clamping head 8 can be automatically unloaded from the cable. During the pause of the intermittent groove wheel 34, the automatic spot winding device 2 automatically spot winds the cables in the unloading area, and the automatic squeezing device 12 realizes the automatic unloading of the point-wound cables, as well as the automatic clamping of the cables in the loading area. At the same time, during the rotation of the fixed clamping head 5 and the movable clamping head 8, the meshing gear 9 on the movable clamping head 8 will gradually contact the spiral gear seat 11 and mesh and rotate. The meshing gear 9 drives the clamp seat 81 as a whole to rotate in the connecting seat 78 through the shaft. The clamp seat 81 drives one end of the cable to rotate and twist the wire through the combined clamp plate 1 82 and clamp plate 2 83, thereby achieving the effect of automatically twisting the cable. During the twisting, the connecting seat 78 at the movable clamping head 8 slides in the spiral groove through the sliding shaft 77 on the sliding air block 75, and the movable clamping head 8 as a whole gradually approaches the fixed clamping head 5 along the spiral groove according to the angle of revolution, thereby achieving the effect of automatically adapting the clamping distance of the cable by the movable clamping head 8 according to the degree of cable twisting.The technical solution arranges multiple groups of fixed clamping heads 5 and movable clamping heads 8 in a circular array to achieve the effect of sequentially twisting and spot winding of multiple groups of cables, occupies a small space, and can realize spot winding of twisted cables during cable loading and unloading. Automatic twisting of cables can be performed during cable operation and replacement, making full use of the working time of the cables to achieve the effect of efficient twisting and spot winding of the cables.
