DETAILED DESCRIPTION

[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 outside, the pulling assembly comprises two limiting plates 31 fixedly connected to the outside of the laser welding gun 1, the second slide rod 30 is fixedly connected between the limiting plate 31 and the laser welding gun 1, the pulling plate 29 is slidably connected to the outside of the second slide rod 30, the third spring 32 is fixedly connected between the pulling plate 29 and the laser welding gun 1, and the switch button 33 is fixedly connected to the outside of the laser welding gun 1.

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

[0052] When working, the pulling plate 29 is moved to compress the third spring 32, the connecting plate 20 is driven to rotate by the pull rod 28, and when the ball 26 is completely separated from the laser welding gun 1, the pulling plate 29 is in contact with and presses the switch button 33, so that the laser welding gun 1 can weld the object.

[0053] The cable joint sheath welding method comprises the following specific construction steps:

[0054] S1: copper-aluminum composite material is purchased first, then the ring-shaped structure is processed, then the ring-shaped structure and the flange interface are placed together, the placed object is placed on the placing seat 14, and the object is clamped by the clamping block 16;

[0055] S2: after the position of the object is fixed, the carbon steel pipe 8 is pulled to deform the carbon steel pipe 8, so that the position of the laser welding gun 1 is changed, the end of the laser welding gun 1 is close to the position to be welded on the object, the limiting rod 11 is pulled to change the position of the sliding block 9, and then the position of the end of the laser welding gun 1 is changed, so that the end of the laser welding gun 1 is close to the welding position of the object;

[0056] S3: after the laser welding gun 1 is close to the welding position of the object, the barrel 6 is rotated to change the length of the exposed screw rod 5, so that the orientation of the end of the laser welding gun 1 is changed in cooperation with the supporting plate 2, and then the end of the laser welding gun 1 is oriented to the position to be welded on the object;

[0057] S4: after the end of the laser welding gun 1 is aligned with the welding position of the object, the pulling plate 29 is pressed to compress the limiting plate 31, and then the switch button 33 is pressed, so that the laser welding gun 1 welds the object;

[0058] S5: In the process of moving the pull plate 29, the pull rod 28 is driven to move, thereby driving the connecting plate 20 to rotate, further driving the mounting frame 23 to move, so that the outer side of the ball 26 is separated from the inside of the laser welding gun 1, thereby enabling the laser welding gun 1 to be separated from the object welding position, and the end of the laser welding gun 1 is not blocked from the object welding position.

[0059] S6: When the laser welding gun 1 is started, the object welding position is welded, at this time, the laser welding gun 1 is moved, thereby driving the carbon steel pipe 8 to move, further driving the sliding block 9 and the sliding seat 10 to move, thereby driving the rotating ring 12 to rotate in the base 13, so as to weld the object in the plane position of 360 degrees.

[0060] Working principle: by pulling the clamping block 16, the first spring 18 is compressed, then the object is placed between the two clamping blocks 16, then the clamping block 16 is loosened, so as to clamp the object.

[0061] Then the position of the laser welding gun 1 can be limited by the supporting plate 2, then the first rotating seat 4 is rotated, so as to limit the position of the laser welding gun 1, then the laser welding gun 1 is pressed, thereby making the carbon steel pipe 8 deform, so that the end of the laser welding gun 1 is close to the object welding position, then the cylinder 6 is rotated, thereby changing the direction of the end of the laser welding gun 1 with the supporting plate 2, so that the end of the laser welding gun 1 is directed to the welding position, when welding, the laser welding gun 1 can be pulled, so that the rotating ring 12 rotates along the base 13, thereby facilitating the welding of the object in the same plane of 360 degrees, thereby ensuring the stability of the object, reducing the welding blank, thereby reducing the possibility of subsequent falling off.
