Description

Technical Field

[0001] This invention belongs to the field of cable sheath welding, specifically a cable joint sheath welding device and method. Background Technology

[0002] Sheaths are industrial insulating and protective materials, mainly used for the outer layer protection of wires, electrical terminals and cables, covering fields such as electrical appliances, automobiles, air conditioners, communication equipment and construction sites.

[0003] When protecting the cable, first place the sleeve outside the cable aluminum cylinder, then connect the cable, and weld the copper-aluminum structural components to the flange and cable aluminum cylinder respectively. Next, fit the metal cylindrical clamp onto the outside of the cable aluminum cylinder, and then inject adhesive between the metal cylindrical clamp and the cable aluminum cylinder to complete the installation.

[0004] However, the copper parts of the structural components and the flange interfaces need to be welded in advance. When welding these parts, a handheld laser welding gun is generally used. However, handheld welding guns can lead to unstable welding, which may result in gaps in the weld, making the seal inadequate. Furthermore, strong pulling may cause them to fall off.

[0005] Therefore, the present invention provides a cable joint sheath welding device and method. Summary of the Invention

[0008] Preferably, an installation assembly is provided on the outer side of the rotating ring. The installation assembly includes a base slidably connected to the outer side of the rotating ring, a placement seat is fixedly connected inside the base, and a limiting rod is fixedly connected to the top of the placement seat.

[0009] Preferably, the mounting assembly further includes a first slide rod fixedly connected inside the placement seat, a clamping block slidably connected to the outside of the first slide rod, a first spring fixedly connected between the clamping block and the placement seat, and an auxiliary block fixedly connected to the top of the placement seat.

[0010] Preferably, a shielding assembly is provided on the outside of the laser welding gun. The shielding assembly includes two connecting plates rotatably connected to the outside of the laser welding gun. A torsion spring is fixedly connected between the connecting plates and the laser welding gun. A connecting rod is fixedly connected to the outside of the connecting plates.

[0011] Preferably, the shielding assembly further includes a mounting frame fixedly connected between the two connecting rods, a movable frame slidably connected inside the mounting frame, a second spring fixedly connected between the movable frame and the mounting frame, a ball bearing slidably connected inside the movable frame, and the outer side of the ball bearing slidably connected to the inside of the laser welding gun.

[0012] Preferably, a pulling assembly is provided on the outside of the laser welding gun. The pulling assembly includes two limiting plates fixedly connected to the outside of the laser welding gun. A second sliding rod is fixedly connected between the limiting plates and the laser welding gun. A pull plate is slidably connected to the outside of the second sliding rod. A third spring is fixedly connected between the pull plate and the laser welding gun. A switch button is fixedly connected to the outside of the laser welding gun.

[0013] Preferably, the pulling assembly further includes a pull rod fixedly connected to the outside of the pull plate, and an auxiliary rod is slidably connected inside the pull rod, the auxiliary rod being fixedly connected between the two connecting plates.

[0014] Preferably, the sliding seat is positioned higher than the placement seat, and the end of the sliding seat does not contact the placement seat.

[0015] Preferably, the clamping block is configured as a ring, and the auxiliary block is configured as a ring.

[0016] The cable joint sheath welding method of the present invention includes the following specific construction steps:

[0017] S1: First, purchase copper-aluminum composite material, then process it into a ring structure, then place the ring structure together with the flange interface, and place the objects placed together on the placement seat, and clamp the objects with clamping blocks.

[0018] S2: After the position of the object is fixed, the carbon steel pipe is pulled, which causes the carbon steel pipe to deform, thereby changing the position of the laser welding gun. This brings the end of the laser welding gun closer to the position on the object that needs to be welded. The limit rod is pulled, which changes the position of the slider, thereby changing the position of the end of the laser welding gun, so that the end of the laser welding gun is closer to the welding position.

[0019] S3: When the laser welding gun approaches the welding position of the object, the screw barrel is rotated to change the exposed length of the screw, thereby changing the orientation of the laser welding gun tip in conjunction with the support plate, so that the laser welding gun tip faces the position on the object that needs to be welded.

[0020] S4: After the tip of the laser welding gun is aligned with the welding position of the object, press the pull plate to compress the limit plate, thereby pressing the switch button, so that the laser welding gun can weld the object.

[0021] S5: During the movement of the pull plate, the pull rod will move, which will cause the connecting plate to rotate, and then the mounting frame to move, so that the outer side of the ball slides with the inside of the laser welding gun, thereby squeezing the second spring. When the pull plate is about to approach the switch button, the ball will completely separate from the laser welding gun, so that there is no obstruction between the end of the laser welding gun and the welding position of the object.

[0022] S6: When the laser welding gun is activated, it will weld the object at the welding position. At this time, the laser welding gun is moved, which in turn moves the carbon steel pipe, which in turn moves the slider and sliding seat, which in turn drives the rotating ring to rotate inside the base, thereby welding the object in a 360-degree planar position.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. This invention uses a support plate to restrict the position of the laser welding gun. Then, rotating the first rotating seat further restricts the position of the laser welding gun. Pressing the laser welding gun causes deformation of the carbon steel pipe, bringing the end of the laser welding gun closer to the welding position on the object. Next, rotating the screw cylinder, in conjunction with the support plate, changes the orientation of the laser welding gun end towards the welding position. During welding, pulling the laser welding gun causes the rotating ring to rotate along the base, facilitating 360-degree welding of the object on the same plane. This ensures welding stability, reduces gaps in the weld, and lowers the possibility of subsequent detachment.

[0025] 2. The present invention compresses the first spring by pulling open the clamping block, then places the object between the two clamping blocks, and then releases the clamping block to clamp the object. In addition, the limiting rod can improve the stability of the object placement.

[0026] 3. This invention rotates the connecting plate, thereby rotating the torsion spring and moving the connecting rod, which in turn moves the mounting frame, which in turn moves the moving frame and the ball bearing. When the outer side of the ball bearing comes into contact with the inside of the laser welding gun, the ball bearing rotates and moves, thereby compressing the second spring and allowing the ball bearing to separate from the laser welding gun. This ensures that the end of the laser welding gun is unobstructed, facilitating welding of objects. After welding, the ball bearing, under the action of the torsion spring, enters the laser welding gun and seals the end of the laser welding gun, reducing the possibility of external dust and impurities entering the laser welding gun and ensuring the safety of the laser welding gun.

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] Example 1: As Figures 1 to 4 As shown, an embodiment of the present invention provides a cable joint sheath welding device, comprising a laser welding gun 1, two support plates 2 slidably connected inside the laser welding gun 1, the support plates 2 having a certain elasticity, a top plate 3 fixedly connected to the top of the support plates 2, a first rotating seat 4 threadedly connected inside the laser welding gun 1, a screw 5 rotatably connected inside the first rotating seat 4, a screw cylinder 6 threadedly connected to the outside of the screw 5, a second rotating seat 7 rotatably connected to the outside of the screw cylinder 6, the top of the second rotating seat 7 rotatably connected to the bottom of the top plate 3, a carbon steel pipe 8 fixedly connected to the top of the top plate 3, a slider 9 fixedly connected to the end of the carbon steel pipe 8, a sliding seat 10 slidably connected to the outside of the slider 9, a rotating ring 12 fixedly connected to the end of the sliding seat 10, a limiting rod 11 slidably connected inside the slider 9, the limiting rod 11 passing through the sliding seat 10 and slidably connected.

[0038] During operation, the position of the laser welding gun 1 can be restricted by the support plate 2. Then, the first rotating seat 4 is rotated to restrict the position of the laser welding gun 1. Then, the laser welding gun 1 is pressed, which causes the carbon steel pipe 8 to deform, so that the end of the laser welding gun 1 is close to the welding position of the object. Then, the screw 6 is rotated, which, together with the support plate 2, changes the orientation of the end of the laser welding gun 1, so that the end of the laser welding gun 1 faces the welding position. When welding, the laser welding gun 1 can be pulled, so that the rotating ring 12 rotates along the base 13, which facilitates 360-degree welding of the object on the same plane, thereby ensuring the stability of the welding, reducing the occurrence of gaps in the welding, and reducing the possibility of subsequent detachment.

[0039] The rotating ring 12 has an installation component on its outer side. The installation component includes a base 13 that is slidably connected to the outer side of the rotating ring 12. A placement seat 14 is fixedly connected inside the base 13. A limiting rod 15 is fixedly connected to the top of the placement seat 14.

[0040] The installation assembly also includes a first slide bar 17 fixedly connected inside the placement seat 14, a clamping block 16 slidably connected to the outside of the first slide bar 17, a first spring 18 fixedly connected between the clamping block 16 and the placement seat 14, and an auxiliary block 19 fixedly connected to the top of the placement seat 14.

[0041] During operation, the first spring 18 is compressed by pulling open the clamping block 16, and then the object is placed between the two clamping blocks 16. After that, the clamping block 16 is released to clamp the object. In conjunction with the limiting rod 15, the stability of the object placement can be improved.

[0042] The sliding seat 10 is positioned higher than the placement seat 14, and the end of the sliding seat 10 does not contact the placement seat 14.

[0043] During operation, by setting the sliding seat 10 higher than the placement seat 14, the placement seat 14 will not affect the sliding seat 10 when it rotates.

[0044] The clamping block 16 is set as a ring, and the auxiliary block 19 is set as a ring.

[0045] During operation, by setting the clamping block 16 as a ring, it is easier to clamp ring-shaped objects, and by setting the auxiliary block 19 as a ring, the contact area between the auxiliary block 19 and the clamping block 16 is increased.

[0046] Example 2: Figures 5 to 6 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a shielding assembly is provided on the outside of the laser welding gun 1. The shielding assembly includes two connecting plates 20 rotatably connected to the outside of the laser welding gun 1. A torsion spring 21 is fixedly connected between the connecting plates 20 and the laser welding gun 1. A connecting rod 22 is fixedly connected to the outside of the connecting plates 20.

[0047] The shielding component also includes a mounting frame 23 fixedly connected between two connecting rods 22. A movable frame 24 is slidably connected inside the mounting frame 23. A second spring 25 is fixedly connected between the movable frame 24 and the mounting frame 23. A ball bearing 26 is slidably connected inside the movable frame 24. The outer side of the ball bearing 26 is slidably connected to the inside of the laser welding gun 1.

[0048] During operation, the rotation of the connecting plate 20 rotates the torsion spring 21, which in turn moves the connecting rod 22, thereby moving the mounting frame 23, which in turn moves the moving frame 24 and the ball bearing 26. When the outer side of the ball bearing 26 comes into contact with the inside of the laser welding gun 1, the ball bearing 26 rotates and moves, thereby compressing the second spring 25, which allows the ball bearing 26 to separate from the laser welding gun 1, thus leaving the end of the laser welding gun 1 unobstructed and facilitating the welding of objects.

[0049] After welding is completed, the ball bearing 26 will enter the laser welding gun 1 under the action of the torsion spring 21, thereby sealing the end of the laser welding gun 1 and reducing the possibility of external dust and impurities entering the laser welding gun 1, thus ensuring the safety of the laser welding gun 1.

[0050] The laser welding gun 1 is provided with a pulling assembly on its outer side. The pulling assembly includes two limiting plates 31 fixedly connected to the outer side of the laser welding gun 1. A second sliding rod 30 is fixedly connected between the limiting plate 31 and the laser welding gun 1. A pull plate 29 is slidably connected to the outer side of the second sliding rod 30. A third spring 32 is fixedly connected between the pull plate 29 and the laser welding gun 1. A switch button 33 is fixedly connected to the outer side of the laser welding gun 1.

[0051] The pulling assembly also includes a pull rod 28 fixedly connected to the outside of the pull plate 29, and an auxiliary rod 27 slidably connected inside the pull rod 28. The auxiliary rod 27 is fixedly connected between the two connecting plates 20.

[0052] During operation, the third spring 32 is compressed by the movement of the pull plate 29, and the connecting plate 20 is rotated by the pull rod 28. When the ball 26 is completely separated from the laser welding gun 1, the pull plate 29 will contact and press the switch button 33, so that the laser welding gun 1 can weld the object.

[0053] The present invention provides a method for welding cable joint sheaths, the specific construction steps of which are as follows:

[0054] S1: First, purchase copper-aluminum composite material, then process it into a ring structure, then place the ring structure together with the flange interface, and place the objects placed together on the placement seat 14, and clamp the objects with the clamping block 16.

[0055] S2: After the position of the object is fixed, the carbon steel pipe 8 is pulled, which causes the carbon steel pipe 8 to deform, thereby changing the position of the laser welding gun 1, so that the end of the laser welding gun 1 is close to the position to be welded on the object, and the limiting rod 11 is pulled, thereby changing the position of the slider 9, which in turn changes the position of the end of the laser welding gun 1, so that the end of the laser welding gun 1 is close to the welding position;

[0056] S3: When the laser welding gun 1 approaches the welding position of the object, the screw barrel 6 is rotated to change the exposed length of the screw 5, thereby changing the orientation of the end of the laser welding gun 1 in conjunction with the support plate 2, so that the end of the laser welding gun 1 faces the position on the object that needs to be welded.

[0057] S4: When the end of the laser welding gun 1 is aligned with the welding position of the object, the pull plate 29 is pressed to compress the limit plate 31, thereby pressing the switch button 33, so that the laser welding gun 1 welds the object.

[0058] S5: During the movement of the pull plate 29, the pull rod 28 will move, thereby causing the connecting plate 20 to rotate, which in turn causes the mounting frame 23 to move, so that the outer side of the ball 26 slides with the inside of the laser welding gun 1, thereby squeezing the second spring 25. When the pull plate 29 is about to approach the switch button 33, the ball 26 will completely separate from the laser welding gun 1, so that there is no obstruction between the end of the laser welding gun 1 and the welding position of the object.

[0059] S6: When the laser welding gun 1 is activated, it will weld the object at the welding position. At this time, the laser welding gun 1 is moved, which drives the carbon steel pipe 8 to move, and then drives the slider 9 and the sliding seat 10 to move, which drives the rotating ring 12 to rotate inside the base 13, thereby welding the object in a 360-degree planar position.

[0060] Working principle: By pulling open the clamping block 16, the first spring 18 is compressed. Then, the object is placed between the two clamping blocks 16. After that, the clamping block 16 is released to clamp the object.

[0061] The position of the laser welding gun 1 can then be restricted by the support plate 2. The first rotating seat 4 is then rotated to restrict the position of the laser welding gun 1. The laser welding gun 1 is then pressed, causing the carbon steel pipe 8 to deform, thereby bringing the end of the laser welding gun 1 closer to the welding position of the object. Then, the screw 6 is rotated, which, in conjunction with the support plate 2, changes the orientation of the end of the laser welding gun 1, so that the end of the laser welding gun 1 faces the welding position. When welding, the laser welding gun 1 can be pulled, causing the rotating ring 12 to rotate along the base 13, thereby facilitating 360-degree welding of the object on the same plane, thus ensuring the stability of the welding, reducing gaps in the welding, and reducing the possibility of subsequent detachment.
