[0002] A copper rod welding machine is an automated or semi-automated device specifically designed for welding copper rods. Its core objective is to fuse the joints of copper rods together using physical or chemical methods to form a strong and electrically conductive joint. Because copper has extremely high thermal conductivity, a high melting point, and is easily oxidized, ordinary welding methods cannot achieve high-quality connections. Therefore, specialized equipment and technology are required to ensure the welding effect.

[0003] Compared to existing welding equipment, there are still the following drawbacks: Conventional welding equipment only performs welding and fusion from one side. When welding the other side, the copper rod needs to be removed and flipped and fixed, which not only wastes manpower and time but also reduces work efficiency. At the same time, different copper rods have different sizes and require the use of different types of clamps for fixing, which can easily lead to excessively high equipment costs. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 Please see Figure 1 , Figure 2 and Figure 3 As shown, this utility model is a laser welding device for processing copper rods. Specifically, it is capable of positioning and centering copper rods of different lengths and diameters. It includes a fixed mounting base plate 1, a reciprocating lead screw 3 on the inner side of the fixed mounting base plate 1, a movable connecting block 4 on the outer side of the reciprocating lead screw 3, a receiving frame 6 for clamping the copper rod on the upper end of the movable connecting block 4, an outer frame 7 on the upper end of the fixed mounting base plate 1, a hydraulic telescopic rod 8 on the inner side of the outer frame 7, and a welding machine body 9 on the lower end of the hydraulic telescopic rod 8.

[0019] In this embodiment, preferably, the reciprocating lead screw 3 and the movable connecting block 4 are connected by threads. The thread direction of the reciprocating lead screw 3 is set to be opposite to the center line of the fixed mounting base plate 1. When the first servo motor 2 is turned on to rotate the reciprocating lead screw 3, it can drive the receiving frame 6 connected to the outer thread of the reciprocating lead screw 3 to move in opposite directions.

[0020] In this embodiment, preferably, the lower end of the movable connecting block 4 is provided with fixed limiting rods 5 on both the front and rear sides, located inside the fixed mounting base plate 1. The movable connecting block 4 forms a nested sliding structure on the fixed limiting rods 5, which makes the overall lateral movement of the receiving frame 6 more stable.

[0021] In summary, firstly, the fixed mounting base plate 1 is stably placed in the designated position. Then, two copper rods of the same size and specifications are placed inside the receiving frame 6, and the cylinder 607 is turned on to drive the movable clamping block 608 to move inward. Then, the copper rods are centered and clamped by the rubber anti-slip block 609 with an arc-shaped longitudinal section bonded to the inside of the movable clamping block 608. Thus, the copper rods can be stably clamped under the action of the symmetrically arranged receiving frame 6. Since the receiving frame 6 and the reciprocating screw 3 are connected by threads, and the thread direction of the reciprocating screw 3 is set to the left and right opposite to the center line of the fixed mounting base plate 1, when the first servo motor 2 is turned on to rotate the reciprocating screw 3, it can drive the movable connecting block 4, which is threaded to the reciprocating screw 3, to move in opposite directions. This allows the receiving frame 6 to move laterally stably within the fixed mounting base plate 1 through the fixed limiting rod 5. The distance between the two is adjusted according to the length of the copper rods to avoid excessive distance at the connection point.

[0022] When two copper rods of the same size and specifications are positioned within the receiving frame 6, the hydraulic telescopic rod 8 installed on the upper inner side of the outer frame 7 can be opened to lower the welding machine body 9. After the lower end of the welding machine body 9 is in close contact with the connection point of the two copper rods, the welding operation can be performed. The welding machine body 9 can be selected as: argon arc welding copper rod welding machine, resistance welding copper rod welding machine or laser welding copper rod welding machine, and its model can be selected as: Panasonic YD-350DR or ROFIN FL020P.

[0023] Example 2 Reference Figure 1 , Figure 2 and Figure 4 The image shows the second embodiment of this utility model, which is specifically capable of rotating the welded copper rod in a circular motion to reduce the number of weld points. The receiving frame 6 also includes a driven gear disk 605 disposed on the left and right sides. A clamping panel 606 is installed on the outer end of the driven gear disk 605, and a movable clamping block 608 is disposed on the inner side of the clamping panel 606.

[0024] In this embodiment, preferably, the worm 602 and the worm wheel 603 are connected by meshing. The worm wheel 603 is fixedly connected to the connecting gear disk 604 through a connecting rod, so that when the second servo motor 601 is turned on to rotate the worm 602, the worm wheel 603 is driven to rotate synchronously.

[0025] In this embodiment, preferably, the connecting gear disk 604 and the driven gear disk 605 are connected by meshing. The diameter of the connecting gear disk 604 is half the diameter of the driven gear disk 605, so that when the worm gear 603 rotates, it can drive the fixedly connected connecting gear disk 604 to rotate synchronously.

[0026] In this embodiment, preferably, the driven gear disk 605 forms a rotating structure on the receiving frame 6 through a built-in bearing, and the driven gear disk 605 is vertically fixedly connected to the clamping panel 606, which enables the driven gear disk 605 to rotate stably on the upper left and right sides of the receiving frame 6.

[0027] In this embodiment, preferably, the driven gear disk 605 is arranged symmetrically about the center line of the receiving frame 6, and the receiving frame 6 is arranged symmetrically about the center line of the reciprocating lead screw 3, so that the two copper rods can be stably clamped and positioned under the action of the symmetrically arranged receiving frame 6.

[0028] In this embodiment, preferably, the movable clamping block 608 and the rubber anti-slip block 609 are bonded together. The longitudinal sections of both the movable clamping block 608 and the rubber anti-slip block 609 are arc-shaped, which can stably clamp the movable clamping block 608 under the action of the rubber anti-slip block 609 when the movable clamping block 608 is driven inward.

[0029] In summary, in conjunction with Embodiment 1, during the welding process, after the copper rods are joined, the welding machine body 9 can only weld one end of the copper rod connection. At this time, the second servo motor 601 is turned on to rotate the worm gear 602, so that the worm wheel 603, which meshes with the worm gear 602, can rotate synchronously. Since the worm wheel 603 is fixedly connected to the connecting gear disk 604 through the connecting rod, when the worm wheel 603 rotates, the connecting gear disk 604 drives the driven gear disk 605 to rotate synchronously and in the same direction on the left and right sides of the upper end of the receiving frame 6 through the built-in bearing. Since the diameter of the connecting gear disk 604 is half the diameter of the driven gear disk 605, the driven gear disk 605 can rotate at a uniform and slow speed. In conjunction with the operation of the welding machine body 9, the copper rod can be welded around different surfaces in a circular manner, so as to reduce the number of weld points.

[0030] Example 3 This embodiment is obtained by combining Embodiment 1 and Embodiment 2.

[0031] The above method involves positioning and clamping copper rods of different lengths and diameters, and rotating the copper rods in a circular motion to achieve uniform welding at the joints, thereby reducing the number of weld points.

[0032] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
