Description

Technical Field

[0001] This invention relates to the field of welding, and in particular to a welding apparatus and method for cable processing equipment. Background Technology

[0002] Cable fusion splicing is a type of welding process called fusion welding. Its core is to achieve a permanent connection by melting metal at high temperatures, rather than crimping or brazing. Cable fusion splicing is an engineering technology that permanently connects the conductor, insulation layer, and other parts of a cable through a specific process. The cable core is placed in a special mold and clamped in place. Then, copper gaskets, a whole bag of copper soldering powder, and ignition powder are placed in sequence, ensuring that the ignition powder covers the ignition port. After sealing the mold, it is ignited, and the reaction generates high-temperature molten copper liquid, which fuses the conductors together.

[0003] Cable splicing is usually done manually by holding a welding mold and clamping the cables together for welding. The waste generated after welding will be attached to the cable and needs to be cut manually. The high degree of manual involvement in the cable splicing process makes the welding process quite inconvenient. Summary of the Invention

[0016] A welding method for a welding device in a cable processing equipment includes the following steps:

[0017] S1: First, place the two sections of cable in the U-shaped clamp of the first clamping mechanism, then place the ends of the two sections of cable to be welded on the arc-shaped support groove, and then control the movement of the clamping plate to clamp the cable. After the second clamping mechanism clamps and fixes the two sections of cable, control the two second telescopic cylinders to push the two second clamping components to move relative to each other to achieve splicing of the two cable welding ends.

[0018] S2: Then control the two half molds to move relative to each other to achieve splicing, and store the cable in the two first chambers.

Then drive the cutting body and the cutting blade to work and remove the welding waste at both ends of the weld.

[0020] Beneficial effects

[0021] 1. The present invention is provided with a first clamping mechanism and a second clamping mechanism. The first clamping mechanism supports the two sections of cable and lifts them after welding. The second clamping mechanism is used to splice the two sections of cable. The cable is clamped on the two second clamping mechanisms respectively, and then the relative movement of the two is controlled to achieve splicing of the two sections of cable. At the same time, after the cable welding is completed, the two second clamping mechanisms can also cooperate to move the welded cable to the cutting mechanism for cutting, and remove excess waste at the weld joint of the cable.

[0022] 2. This invention achieves automatic splicing and separation of two half-molds by providing a splicable welding mold. When splicing the two half-molds, the cable to be welded is wrapped inside the half-mold, and welding is achieved with the help of welding flux. After welding, the two half-molds move to both ends and rotate the welding chamber outward to facilitate cleaning of the welding chamber.

[0023] 3. The present invention achieves the removal of welding waste by means of a cutting mechanism. The cutting mechanism includes two semi-circular tracks, which can be spliced ​​together to form a complete track. When the second clamping mechanism moves the welded cable to the cutting area, the splicing of the two semi-circular tracks can be completed simultaneously, making the cutting process more continuous and the cutting efficiency after welding higher.

A cutting mechanism 600 is also slidably provided on the workbench 100 next to the welding mold 500. After the two sections of cable 400 are welded, there will be molten waste at the upper and lower ends of the weld. At this time, the cutting mechanism 600 is used to cut it.

[0036] like Figure 2As shown, the workbench 100 includes a tabletop 101 and support legs 102. Two first mounting plates 103 are fixedly installed at the bottom of the tabletop 101. The two first mounting plates 103 are symmetrically arranged. The first clamping mechanism 200 includes two sets of first telescopic cylinders 201 and first telescopic rods 202. The two sets of first telescopic cylinders 201 and first telescopic rods 202 are respectively fixedly installed on the two first mounting plates 103. The cylinder body of the first telescopic cylinder 201 is fixedly installed on the first mounting plate 103. One end of the first telescopic rod 202 is fixedly fixed to the top of the first mounting plate 103. The output ends of the two sets of first telescopic cylinders 201 and the extension ends of the first telescopic rods 202 are all fixedly connected to U-shaped clamps 203. The first telescopic cylinder 201 controls the U-shaped clamps 203 on both sides to move up and down. The U-shaped clamps 203 are used to place the cable 400 and can also realize the up and down movement of the cable 400.

[0037] like Figure 2 The second clamping mechanism 300 shown includes two second mounting plates 301 fixedly installed on both sides of the table 101. Two slide rods 302 are fixedly provided between the two second mounting plates 301. A second telescopic cylinder 303 is fixedly provided on each of the two second mounting plates 301. A second clamping component is fixedly provided at the output end of each of the two second telescopic cylinders 303. The two second clamping components are slidably connected to the slide rods 302, that is, the distance between the two second clamping components can be adjusted.

[0038] like Figure 3 and Figure 4 As shown, the second clamping assembly includes a mating base 304, which is fixedly connected to the output end of the second telescopic cylinder 303. The mating base 304 is slidably connected to two sliding rods 302. A third telescopic cylinder 305 is fixedly mounted on the mating base 304, and a connector 306 is fixedly mounted on the output end of the third telescopic cylinder 305. Two support back plates 310 are symmetrically mounted on the mating base 304, and both support back plates 310 are fixedly connected to the mating base 304. A third mounting plate 307 is fixedly mounted on each of the two support back plates 310, and a bent connecting rod 308 is rotatably mounted on each of the two third mounting plates 307. The middle position of the bent connecting rod 308 is rotatably connected to the two third mounting plates 307. One end of the two bent connecting rods 308 is rotatably connected to the connector 306, and the other end of the two bent connecting rods 308 is rotatably connected to the clamping plate 309. The clamping plate 309 is slidably connected to the two support back plates 310 respectively. A fourth mounting plate 311 is fixedly provided between the two support back plates 310. An arc-shaped support groove 312 is fixedly provided in the middle position of the fourth mounting plate 311. In use, the cable 400 is placed on the arc-shaped support groove 312, and then the output end of the third telescopic cylinder 305 is controlled to move upward. The connector 306 moves upward, causing the two bent connecting rods 308 to rotate, further realizing the lateral movement of the clamping plate 309. When the two clamping plates 309 move towards each other, the cable 400 is clamped.

[0039] In use, the cable 400 is placed on the two second clamping components respectively, and then the clamping plate 309 is controlled to clamp the cable 400. After clamping, the two clamping components are driven to move by the second telescopic cylinder 303 to align the two sections of cable 400, which facilitates subsequent welding.

[0040] like Figure 5 As shown, the welding mold 500 includes a mounting groove 501, which is fixedly connected to the table surface 101. A first threaded rod 502 and a first limiting rod (not marked in the figure) are fixedly provided in the mounting groove 501. The two ends of the first threaded rod 502 have opposite thread directions, and a first motor is fixedly provided at one end of the first threaded rod 502. The first motor drives the first threaded rod 502 to rotate. Half molds are threadedly fitted at the two ends of the first threaded rod 502 with opposite thread directions. The two half molds are engaged to form a complete welding mold 500. The half mold includes a mating block 504. A first gear 505 is rotatably provided on the mating block 504. A connecting block 506 is fixedly provided on the first gear 505. A rectangular welding area 507 is fixedly connected to the connecting block 506. The top of the 07 is fixedly provided with a receiving area 508, and the top of one of the receiving areas 508 is fixedly provided with a cover plate 509. The receiving area 508 is provided with a receiving cavity 510. The rectangular welding area 507 is provided with a first chamber 512 horizontally and a second chamber 511 vertically. The two first chambers 512 are spliced ​​together to form a first cylindrical chamber, and the two second chambers 511 are spliced ​​together to form a second cylindrical chamber. The first cylindrical chamber is used to accommodate the connection of the stripped cable 400. The receiving cavity 510 is used to place the welding flux. When in use, the welding flux is ignited, and the melted welding flux enters the first chamber 512 through the second chamber 511. After cooling, the two sections of cable 400 are welded. After welding, the second chamber 511 will have excess welding waste, which needs to be removed.

[0041] After welding, the mold is moved to both ends to achieve demolding. Both ends of the mounting groove 501 are provided with a first rack 503. During the process of the two half molds moving to both ends, the first gear 505 meshes with the first rack 503 to drive the rotation of the two half molds, thereby rotating the second chamber 511 and the first chamber 512 to the outward direction, which facilitates the cleaning of the second chamber 511 and the first chamber 512 inside the two half molds.

[0042] like Figure 6 , Figure 7 and Figure 8As shown, the cutting mechanism 600 includes two fifth mounting plates 601, with a second limiting rod 602 fixedly disposed between the two fifth mounting plates 601. Second threaded rods 603 are rotatably disposed on each of the two fifth mounting plates 601. One end of each of the two second threaded rods 603 is connected to a second motor 613, and the other ends of both second threaded rods 603 are coaxially aligned and fixedly provided with second gears 604. An L-shaped rod 605 is fixedly disposed on a second clamping assembly near the end of the cutting mechanism 600. A second rack 606 is fixedly disposed on the L-shaped rod 605. Two components are provided, symmetrically and fixedly mounted on the mating base 304. When the second clamping assembly moves, it gradually engages with the second rack 606 fixedly connected to it, thereby rotating the two second gears 604. The rotation of the two second gears 604 further rotates the two second threaded rods 603. Each of the two second threaded rods 603 is threadedly fitted with a movable bracket 607. A semi-circular track 608 is fixedly mounted on each of the two movable brackets 607. The two semi-circular tracks 608 are spliced ​​together to form a complete circular track, such as... Figure 7 Both semicircular tracks 608 shown have track grooves 610. A cutting device is slidably mounted in the track grooves 610. The cutting device includes a cutting body 609 and a cutting disc 611. The cutting disc 611 is rotatably mounted on the cutting body 609. A drive assembly 612 is installed on the cutting device. The drive assembly 612 enables the cutting device to move on the semicircular tracks 608. In this embodiment, the drive assembly 612 includes a third gear, a third rack, and a third motor. The third gear is rotatably connected to the cutting device. The third rack is fixedly mounted in the track groove 610 and has the same shape as the track groove 610. The third motor drives the third gear to rotate and is slidably mounted in the track groove 610. When the third motor drives the third gear to rotate, the third gear meshes with the third rack, enabling the third gear to move on the third rack, and further enabling the cutting body 609 to move on the track groove 610.

[0043] In use, when the second clamping assembly moves, the second rack 606 fixedly connected to it gradually meshes with the two second gears 604, realizing the rotation of the two second gears 604. The rotation of the two second gears 604 further realizes the rotation of the two second threaded rods 603. The rotation of the two second threaded rods 603 realizes the movement of the two moving supports 607 until the two semi-circular tracks 608 are spliced ​​to form a complete track. Then the cutting disc 611 is started and the cutting equipment is driven to move along the complete track to realize the cutting of the waste at both ends after welding.

[0044] A welding method for a cable welding device includes the following steps:

[0045] S1: First, place the two sections of cable 400 in the U-shaped clamp 203 of the first clamping mechanism 200, then place the ends of the two sections of cable 400 to be welded on the arc-shaped support groove 312, and then control the movement of the clamping plate 309 to clamp the cable 400. After the second clamping mechanism 300 clamps and fixes the two sections of cable 400, control the two second telescopic cylinders 303 to push the two second clamping components to move relative to each other to achieve the splicing of the welding ends of the two cables 400.

[0046] S2: Then control the two half molds to move relative to each other to achieve splicing, and store the cable 400 in the two first chambers 512. Then pour welding flux into the receiving cavity 510, ignite the welding flux and cover the cover plate 509. The molten welding flux flows into the welding end surface of the two cables 400 through the second chamber 511. The two cables 400 are welded. After the welding is completed, the two half molds are separated and moved to both ends for cleaning.

[0047] S3: Then control the second clamping mechanism 300 to continuously clamp the welded cable 400, and with the cooperation of the two second telescopic cylinders 303, realize the lateral movement of the cable 400. The welded part of the cable 400 moves to the cutting mechanism 600. During the movement of the second clamping mechanism 300, the splicing of the two semi-circular tracks 608 can be realized simultaneously. Then drive the cutting body 609 and the cutting blade 611 to work and remove the welding waste at both ends of the weld.
