Description

Technical Field

[0001] The present invention relates to the technical field of wire stranding machines, in particular to a wire stranding device for producing electronic wire harnesses. Background Art

[0002] An electronic wiring harness is an assembly consisting of multiple cables or wires, mainly used to connect various parts of electronic equipment to transmit current, signals or energy. It combines multiple wires together through twisting, covering, binding and other processes. In the production process of electronic wiring harnesses, twisting equipment plays a vital role. It can mechanically twist multiple wires or single-core wires of cables with each other and process them according to specific standards and forms to form a cable with a multi-strand structure. This type of wiring harness is widely used in wire and cable production, communications, electronics industry and other fields.

[0003] However, the existing stranding equipment has the following shortcomings:

[0004] The wire drum of the stranding equipment in the prior art cannot automatically tighten according to the reduction of the wires, which may easily cause the wires to crack due to excessive tension during the wire splitting process. In addition, the wire splitting disk of the equipment cannot adjust the diameter of the card interface according to the diameter of the wires. It only relies on the cylinder to press the wires of different diameters, which may easily make the wire tension too tight and cause cracking. There are certain limitations. While the wire splitting disk adapts to different wires, the diameter of the wire winding drum should be adjusted. However, the existing wire stranding equipment usually adopts a snap spring structure to realize the wire winding drum to clamp wires of different diameters. Although the structure is easy to adjust, it is easy to cause the clamping block of the wire winding drum to loosen, and the stability of the wire winding drum cannot be guaranteed, posing a safety hazard. In addition, the existing wire stranding equipment mostly uses bolts to fix the winding drum. When replacing the winding drum to adapt to the winding of different numbers of wires, it is necessary to use tools to disassemble and assemble the bolts. The operation is cumbersome and not conducive to the rapid replacement of the winding drum.

[0005] Therefore, we propose a stranding device for electronic wire harness production in order to solve the above problems. Summary of the Invention

[0006] The object of the present invention is to provide a stranding device for electronic wire harness production, which realizes the self-adjustment function of wire tension and can adjust the card interface according to the different wire diameters.

At this time, the movable block and the rotating rod on the fixed block can be rotated to drive the gear to rotate, and then the gear drives the rack to rotate, so that the card block on the rack moves to a suitable position, and then the card interface on the card block can be adjusted to a diameter suitable for wires of different diameters to pass through, preventing direct pressure on wires of different diameters, causing excessive tension and wire cracking, so that the stranding device can ensure the stability of tension when adapting to wires of different diameters. When the number of wires in the material barrel is reduced, the adjustment block can be driven to move by the reset of the first spring, so that the adjustment block tightens the wires to ensure that the wires are evenly distributed on the wire barrel, so as to solve the problems raised by the above-mentioned background technology.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention realizes the self-adjustment function of the wire tension and can adjust the clamping interface according to the different wire diameters through the arrangement of the first spring, the adjustment block, the fixing bolt, the square through hole, the fixed block, the movable block, the auxiliary wheel, the placement groove, the gear, the rotating rod, the rack, the clamping block, the storage groove, the threaded rod, the third motor, the fixed rod and the bevel gear. The fixed rod and the bevel gear thereon are first driven to rotate by the third motor, thereby driving the threaded rod and the bevel gear thereon to rotate. The movable block is then driven to move by the threaded rod, and its movement path is restricted by the groove, so that the movable block drives the auxiliary wheel and the clamping block to move together. Then, the rotating rod on the movable block and the fixed block is rotated. The gear is driven to rotate, and then the rack is driven to rotate through the gear, so that the clamping block on the rack moves to the appropriate position, and the clamping interface on the clamping block can be adjusted to the size that adapts to the passage of wires of different diameters, avoiding direct pressing on wires of different diameters to cause excessive tension and cause wire cracking, so that the stranding equipment can adapt to wires of different diameters while ensuring the stability of the tension. When the number of wires in the material barrel decreases, the reset effect of the first spring drives the adjustment block to move, so that the adjustment block tightens the wires, ensuring that the wires are evenly distributed on the wire barrel, avoiding the problem in the prior art that the stranding equipment cannot automatically tighten according to the reduction of wires and the problem of adjusting the clamping interface according to different diameters.

[0019] The limit rod is smoothly inserted into the limit slot by means of the deadweight block and the limit rod, thereby realizing a stable limitation between the moving block, the L-shaped long block, the card block and the wire drawing frame. This improvement not only facilitates the replacement of the wire drawing barrel, but also significantly improves its stability, thereby improving the insufficient stability of the wire drawing barrel of the stranding equipment in the prior art.

[0020] 3. The present invention is provided with a rotating column, a winding drum, an electric telescopic rod, a movable plate, an arc-shaped baffle, a docking plate, a fixed cylinder, a mounting hole, an insert rod, a convex notch, a second spring and a protrusion, which realizes a simpler replacement function. First, the protrusion is pressed to drive the second spring to be compressed in the convex notch. Since the height of the bottom of the protrusion is lower than the height of the bottom of the convex notch, the protrusion will shrink in the convex notch. At this time, the insert rod can be taken out of the mounting hole, and then the electric telescopic rod is used to drive the movable plate to move inside the slide groove and push the movable plate out of the slide groove. Then the winding drum is removed for replacement. The replaced winding drum is then sleeved on the rotating column, and the movable plate is driven by the electric telescopic rod to reinsert the slide groove to ensure that the movable plate is just clamped on one side of the winding drum. Then, the insertion rod is inserted into the inner side of the mounting hole by pressing the protrusion, and with the help of the reset effect of the second spring, one end of the protrusion is pressed against the fixed drum, thereby limiting the position of the movable plate, and limiting the moving path of the wire through the arc baffle and the docking plate, which simplifies the replacement process of the winding drum, provides convenience for the replacement of the winding drum, and solves the problem of slow replacement of the winding drum of the stranding equipment in the prior art.

The outer surface of the gear 206 is rotatably connected to a rack 208, and the rack 208 and the gear 206 are engaged with each other. A fixed rod 213 is installed on the output end of the third motor 212, and a bevel gear 214 is fixedly installed on one end of the outer surface of the fixed rod 213 and the threaded rod 211, and the two sets of bevel gears 214 are engaged with each other.

[0034] The effect achieved by the entire embodiment 1 is: the self-adjusting function of the wire tension is realized, and the card interface can be adjusted according to the different wire diameters. First, the fixing bolt 116 is removed from the connecting shaft 111, and the wire barrel 112 is inserted on the connecting shaft 111. Then the fixing bolt 116 is returned to its original position and tightened. Then, the wires on the wire barrel 112 are passed through the lead holes on the clamping block 209 and the lead disk 104 respectively, so that the wires are combined into one and pass through the wire drawing frame 105. The auxiliary wheel 204 can assist the wires on the clamping block 209 to move, and then the wires are wound on the winding drum 402. Then, the first motor 107 can be started, and the first motor 107 drives the distribution plate 103, the lead plate 104, the connecting rod 108 and the connecting wheel 109 to rotate. Then, the connecting wheel 109 drives the belt 110 and the multiple connecting shafts 111 to rotate, so that the connecting shaft 111 drives the wire drum 112 to rotate. At the same time, the distribution plate 103, the lead plate 104 and the connecting shaft 111 are driven by the connecting rod 108 to rotate synchronously, and the wire drum 301 is fixed. The multiple sets of wires will be twisted into one wire, and then the second motor 113 drives the rotating column 40 1. The winding drum 402 and the fixed drum 407 rotate to apply a pulling force to the wire while winding it. When it is necessary to produce wires of different diameters, the third motor 212 can be used to drive the fixed rod 213 and the bevel gear 214 thereon to rotate, thereby driving the threaded rod 211 and the bevel gear 214 thereon to rotate, and then the threaded rod 211 drives the movable block 203 to move, and the groove limits its moving path, so that the movable block 203 drives the auxiliary wheel 204 and the clamping block 209 to move together, and then the movable block 203 and the rotating rod 207 on the fixed block 202 are rotated to drive the gear 20 6 rotates, and then drives the rack 208 to rotate through the gear 206, so that the clamping block 209 on the rack 208 moves to a suitable position, and the clamping interface on the clamping block 209 can be adjusted to the size of the wires of different diameters, so as to avoid directly pressing the wires of different diameters to cause excessive tension and cause the wires to break, so that the stranding equipment can adapt to wires of different diameters while ensuring the stability of the tension. When the number of wires in the material barrel decreases, the reset effect of the first spring 114 drives the adjustment block 115 to move, so that the adjustment block 115 tightens the wires to ensure that the wires are evenly distributed on the wire barrel 112.

[0035] Example 2, according to Figure 3 and Figure 7As shown, the replacement mechanism 3 includes a winding barrel 301, which is plugged into the inner side of the winding frame 105, and a square block 302 is fixedly installed on the outer surface of the winding barrel 301. A square groove is opened on the inner side of the winding frame 105, and the square block 302 is clamped on the inner side of the square groove. An L-shaped long block 303 is fixedly installed on one end of the outer surface of the square block 302, and a moving block 304 is slidably connected to the inner side of the L-shaped long block 303. The moving block 304 A clamping block 305 is fixedly installed on one side of the outer surface, a placing rack 306 is fixedly installed on the top of the wire drawing rack 105, a pull rod 307 is slidably connected to the surface of the placing rack 306, a limiting rod 308 and a counterweight block 310 are fixedly installed on the bottom end of the pull rod 307, and a limiting slot 309 is provided on the top of the clamping block 305, the moving block 304, the L-shaped long block 303 and the wire drawing rack 105, and the limiting rod 308 is clamped on the inner side of the limiting slot 309.

[0036] The effect achieved by the entire embodiment 2 is: a more stable replacement effect is achieved. First, the limit rod 308 is driven out of the limit groove 309 by the pull rod 307, and the moving block 304 and the clamping block 305 are adjusted to the appropriate position. Then, the line winding barrel 301 can be easily removed from the inner side of the square groove for replacement. After the replacement is completed, the limit rod 308 and the counterweight block 310 need to be pulled up by the pull rod 307, and the moving block 304 is pulled apart at the same time, so that it and the L-shaped long block 303 are tightly fitted on the top of the line winding frame 105. Then, align the wire-drawing barrel 301 with the square slot and insert it, and use the moving block 304 to drive the clamping block 305 to embed into the inner side of the wire-drawing frame 105, then loosen the pull rod 307, and with the help of the counterweight block 310 and the weight of the limiting rod 308, the limiting rod 308 is smoothly inserted into the inner side of the limiting groove 309, thereby achieving a stable limit between the moving block 304, the L-shaped long block 303, the clamping block 305 and the wire-drawing frame 105. This improvement not only facilitates the replacement of the wire-drawing barrel 301, but also significantly improves its stability.

[0037] Example 3, according to Figure 3 、 Figure 8 and Figure 9As shown, the winding mechanism 4 includes a rotating column 401, which is installed at the output end of the second motor 113, and a winding drum 402 is sleeved on the outer surface of the rotating column 401, an electric telescopic rod 403 is installed on one side of the outer surface of the fixed plate 106, a sliding groove is provided on the top of the support frame 101, and a movable plate 404 is slidably connected to the inner side of the sliding groove, and an outer surface side of the movable plate 404 is fixedly installed at the output end of the electric telescopic rod 403, an arc baffle 405 is fixedly installed on one side of the outer surface of the fixed plate 106, and a docking plate 406 is slidably connected to the inner side of the arc baffle 405. The connecting plate 406 is fixedly installed on one side of the outer surface of the movable plate 404, and the outer surface of the movable plate 404 is rotatably connected to a fixed cylinder 407. The outer surface of the fixed cylinder 407 and the outer surface of the rotating column 401 are both provided with mounting holes 408, and the inner side of the mounting hole 408 is slidably connected with an insertion rod 409. Both sides of the outer surface of the insertion rod 409 are provided with convex grooves 410, and the inner end of the convex groove 410 is fixedly installed with a second spring 411, and the outer surface end of the second spring 411 is fixedly installed with a protrusion 412, and the bottom height of the protrusion 412 is lower than the bottom height of the convex groove 410.

[0038] The effect achieved by the entire embodiment 3 is: it realizes a simpler replacement function. First, press the protrusion 412 to drive the second spring 411 to compress in the convex groove 410. Since the height of the bottom of the protrusion 412 is lower than the height of the bottom of the convex groove 410, the protrusion 412 will shrink in the convex groove 410. At this time, the insertion rod 409 can be taken out from the mounting hole 408, and then the electric telescopic rod 403 is used to drive the movable plate 404 to move inside the slide groove, and the movable plate 404 is pushed out of the slide groove, and then the winding drum 402 is removed for replacement, and then the replaced winding drum 402 is put on the rotating shaft. On the moving column 401, the electric telescopic rod 403 drives the moving plate 404 to be reinserted into the slide slot to ensure that the moving plate 404 is just clamped on one side of the winding drum 402, and then the insertion rod 409 is inserted into the inner side of the mounting hole 408 by pressing the protrusion 412. With the help of the reset effect of the second spring 411, one end of the protrusion 412 is pressed against the fixed cylinder 407, thereby limiting the position of the moving plate 404, and limiting the moving path of the wire together by the arc baffle 405 and the docking plate 406, which simplifies the replacement process of the winding drum 402 and provides convenience for the replacement of the winding drum 402.

[0039] The working principle of the whole device is as follows: when using the stranding device, first remove the fixing bolt 116 from the connecting shaft 111, and insert the wire drum 112 on the connecting shaft 111, then put the fixing bolt 116 back in place and tighten it, then pass the wire on the wire drum 112 through the lead holes on the clamping block 209 and the lead disk 104 respectively, so that the wires are merged into one and pass through the wire drawing frame 105, and the auxiliary wheel 204 can assist the wire on the clamping block 209 to move, and then the wire is wound on the winding drum 402, and then the first motor 107 can be started, and the first motor 107 drives the distribution disk 103, the lead disk 104, the connecting rod 108 and the connecting wheel 109 to rotate, and then the connecting wheel 109 is used to rotate. The belt 110 and the multiple connecting shafts 111 are driven to rotate, so that the connecting shaft 111 drives the wire placing drum 112 to rotate, and at the same time, the connecting rod 108 drives the distribution disk 103, the lead disk 104 and the connecting shaft 111 to realize synchronous rotation, and the wire winding drum 301 is fixed, and the multiple sets of wires are twisted into one wire. Then, the second motor 113 drives the rotating column 401, the winding drum 402 and the fixed drum 407 to rotate, giving the wire pulling force while winding, and the moving path of the wire is limited by the arc baffle 405 and the docking plate 406. When the number of wires in the material placing drum is reduced, the adjustment block 115 can be driven to move by the reset of the first spring 114, so that the adjustment block 115 adjusts the wires. Tighten to ensure that the wire is evenly distributed on the wire barrel 112, realize the self-adjusting function of the wire tension, and prevent the wire tension from being too large and causing cracking. When it is necessary to produce wires of different diameters, the third motor 212 can be used to drive the fixed rod 213 and the bevel gear 214 thereon to rotate, so that the threaded rod 211 and the bevel gear 214 thereon can be rotated, and then the threaded rod 211 can be used to drive the movable block 203 to move, and the moving path of the movable block 203 can be limited by the groove, so that the movable block 203 drives the auxiliary wheel 204 and the clamping block 209 to move. At this time, the movable block 203 and the rotating rod 207 on the fixed block 202 can be rotated to drive the gear 206 to rotate, and then the gear 206 drives the rack 20 8 is rotated so that the clamping block 209 on the rack 208 moves to the appropriate position, and then the clamping interface on the clamping block 209 can be adjusted to the diameter suitable for wires of different diameters to prevent direct pressure on wires of different diameters, which may cause excessive tension and lead to wire breakage. The multiple sets of lead holes opened on the lead disk 104 can cope with wires of different diameters, so that the stranding equipment can ensure the stability of tension when adapting to wires of different diameters. Then, when replacing the wire barrel 301, it is necessary to use the pull rod 307 to drive the limit rod 308 out of the limit groove 309, and move the moving block 304 and the clamping block 305 to the appropriate position, and then the wire barrel 301 can be removed from the inner side of the square groove for replacement. After the wire barrel 301 is replaced,The locking block 305 is then forced into the inner side of the wire drawing frame 105 by the locking block 304, and the locking block 305 is then forced into the inner side of the wire drawing frame 105 by the locking block 304. The locking block 305 is then forced into the inner side of the wire drawing frame 105 by the locking block 304. The locking block 305 is then forced into the inner side of the wire drawing frame 105, and the locking block 305 is then forced into the inner side of the wire drawing frame 105. The height of the bottom of 410 will cause the protrusion 412 to shrink in the convex notch 410, and the insertion rod 409 can be taken out of the mounting hole 408. Then, the electric telescopic rod 403 drives the movable plate 404 to move inside the slide slot and push the movable plate 404 out of the slide slot. Then, the winding drum 402 is removed for replacement. After that, the replaced winding drum 402 is sleeved on the rotating column 401 and the electric telescopic rod 403 drives the movable plate 404 to be inserted into the slide slot so that the movable plate 404 is just clamped on one side of the winding drum 402. Then, after pressing the protrusion 412 to insert the insertion rod 409 into the mounting hole 408, the reset of the second spring 411 will make one end of the protrusion 412 abut against the fixed cylinder 407, thereby completing the position limit of the movable plate 404, simplifying the replacement process of the winding drum 402 and providing convenience for the replacement of the winding drum 402.
