DETAILED DESCRIPTION

[0028] The following further describes the present application in conjunction with the drawings, and it is necessary to point out here that the following detailed description is only used to further illustrate the present application, and cannot be understood as limiting the protection scope of the present application, and the skilled person in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0029] As Figure 1 , Figure 2 and Figure 3The utility model provides a copper clad aluminum bar welding device, which comprises

[0030] The base 1 is provided with a positioning mechanism, which comprises a first clamping block 4, a second clamping block 7, a first linear displacement member and a second linear displacement member. The first clamping block 4 is arranged on the base 1 through a first support 2. The first linear displacement member is arranged on the base 1. The output end of the first linear displacement member is drivingly connected with the second linear displacement member. The output end of the second linear displacement member is drivingly connected with the second clamping block 7. The displacement direction of the output end of the first linear displacement member is parallel to the displacement direction of the output end of the second linear displacement member. The displacement distance value of the first linear displacement member is greater than that of the second linear displacement member. The opposite end faces of the first clamping block 4 and the second clamping block 7 are respectively provided with clamping grooves for placing the clamping ends of the copper clad aluminum bars 13.

[0031] The welding mechanism is arranged on one side of the base 1 and located between the first clamping block 4 and the second clamping block 7.

[0032] In the above embodiment, one copper clad aluminum bar 13 is clamped and fixed on the first clamping block 4 and the second clamping block 7 through the clamping grooves. The displacement directions of the first linear displacement member and the second linear displacement member are consistent with the extension direction of the copper clad aluminum bar 13. The displacement distance value of the first linear displacement member is greater than that of the second linear displacement member. The first linear displacement member drives the second clamping block 7 to be displaced for the first time, i.e. coarse displacement. Then the second linear displacement member drives the second clamping block 7 to be displaced for the second time, i.e. fine displacement. Thus, when the second clamping block 7 drives the corresponding copper clad aluminum bar 13 to slide towards the direction of the corresponding copper clad aluminum bar 13 close to the first clamping block 4, the first linear displacement member can be used to coarsely adjust the position in a large range and quickly approach the target position. Then the second linear displacement member can be used to finely adjust the position. This step-by-step displacement method can improve the positioning efficiency and ensure that the clamped copper clad aluminum bar 13 is accurately fixed at the required position, thereby reducing the positioning error. Compared with the traditional one-step displacement method of directly displacing the clamping member with the workpiece, the second clamping block 7 extends from the first linear displacement member by a smaller distance, i.e. the overhanging distance of the second clamping block 7 is shortened, thereby ensuring the stability of the second clamping block 7 clamping the copper clad aluminum bar 13 and further ensuring the welding quality of the welding mechanism to the butt joint position of the copper clad aluminum bar 13.

[0033] It should be noted that, as shown in Figure 2 The copper clad aluminum bar 13 has a structure of a copper layer 132 wrapped around an aluminum core 131, and the copper clad aluminum bar 13 is in a long strip shape.

[0034] For example,Figure 3 The first linear displacement member comprises a first displacement driving member 10, a sliding base 9 and a first sliding rail 11. The output end of the first displacement driving member 10 is drivingly connected with the sliding base 9, the sliding base 9 is slidingly connected on the first sliding rail 11, and the first sliding rail 11 is fixedly arranged on the base 1. The base 1 is fixedly arranged with a first limiting block 111. Along the extension direction of the first sliding rail 11, the first limiting block 111 is located on the side of the sliding base 9 away from the first displacement driving member 10, and the sliding base 9 is in abutting fit with the first limiting block 111, so as to constrain the sliding distance of the sliding base 9. The first sliding rail 11 is arranged in pairs, and the sliding base 9 is symmetrically slidingly connected on the first sliding rail 11, which helps the sliding base 9 to slide stably on the base 1.

[0035] Continuously referring to Figure 3 The second linear displacement member comprises a second displacement driving member 8 and a transmission rod 81. The second displacement driving member 8 is arranged on the sliding base 9. The output end of the second displacement driving member 8 is in abutting fit with the transmission rod 81. That is, in the initial state, the output end of the second displacement driving member 8 is separated from the transmission rod 81. In the driving state, the output end of the second displacement driving member 8 pushes and moves the transmission rod 81. The output end of the transmission rod 81 penetrates through the second bracket 82 and is slidingly connected with the second bracket 82. The second bracket 82 is fixedly arranged on the sliding base 9. One end of the transmission rod 81, which is located on the side of the second bracket 82 away from the second displacement driving member 8, is fixedly connected with the second clamping block 7.

[0036] It should be noted that the first displacement driving member 10 and the second displacement driving member 8 are respectively a gas cylinder, a hydraulic telescopic cylinder, etc., which are not limited here. After the copper-clad aluminum bar 13 is installed on the second clamping block 7, the first displacement driving member 10 is started to drive the sliding base 9 to move rightward (for example, in the orientation shown in Figure 3 Then, under the driving of the second displacement driving member 8, the driving end of the second displacement driving member 8 abuts and pushes the transmission rod 81 to slide. Figure 3As shown, the structure of the output end of the second displacement driving member 8 abutting against the transmission rod 8 is shown, realizing that the second clamp block 7 drives the copper-clad aluminum row 13 to move right and extrude the butt joint of the corresponding copper-clad aluminum row 13 of the first clamp block 4, wherein the right moving distance of the sliding seat 9 is greater than the right moving distance of the second clamp block 7 relative to the second support 82, so that compared with the one-step-to-place type extension mode of the traditional clamp, the overhanging part of the second clamp block 7 extending out of the second support 82 is shortened, the supporting capacity of the second clamp block 7 to the copper-clad aluminum row 13 is enhanced, the risk of unstable structure of the second clamp block 7 caused by too long overhanging is reduced, the shaking or deformation of the copper-clad aluminum row 13 in the butt extrusion process is avoided, and the stable butt extrusion process is ensured. For the long copper-clad aluminum row 13, the moving distance of the sliding seat 9 and the second clamp block 7 can be adjusted to flexibly control the butt extrusion process and ensure that the butt extrusion quality is not affected by the specification of the copper-clad aluminum row 13.

[0037] For example, continuing to refer to Figure 3 , the input end of the first clamp block 4 is drivingly connected with the motor 3 through the driving shaft 31, the driving shaft 31 is rotatably connected on the first support 2, and the first support 2 is fixedly arranged on the base 1. Through the driving of the motor 3, the driving shaft 31 drives the first clamp block 4 and the second clamp block 7 to rotate.

[0038] Continuing to refer to Figure 1 and Figure 3 , the welding mechanism includes the electromagnetic induction welding head 5 and the laser welding head 6, one side of the electromagnetic induction welding head 5 is fixedly connected with the cantilever 51, one end of the cantilever 51 adjacent to the base 1 is fixedly connected with the sliding block 53, the sliding block 53 is slidingly connected on the second sliding rail 54, the second sliding rail 54 is fixedly arranged on the base 1, and the laser welding head 6 is arranged on the output end of the mechanical arm 12, wherein the electromagnetic induction welding head 5 is annular.

[0039] In the above embodiment, after the two copper-clad aluminum rows 13 are respectively arranged on the first clamp block 4 and the second clamp block 7, under the step-by-step displacement of the second clamp block 7, the welding ends of the two copper-clad aluminum rows 13 are butted together and extruded, at this time, the electromagnetic induction welding head 5 is sleeved outside the copper-clad aluminum row 13, and the sliding block 53 slides along the second sliding rail 54 until the welding position of the welding ends of the two copper-clad aluminum rows 13 is located at the axial position of the electromagnetic induction welding head 5, that is Figure 3The center of the ring-shaped electromagnetic induction welding head 5 is shown at a position, so that after the electromagnetic induction welding head 5 is powered on, the high-frequency alternating current is turned on, the induction coil of the electromagnetic induction welding head 5 generates a high-frequency alternating magnetic field, and a strong eddy current is generated in the copper-clad aluminum bar 13 due to electromagnetic induction, which relies on eddy current heating to rapidly heat the welding position. When the temperature approaches the melting point of aluminum, the aluminum core 131 is welded and connected. Because the melting point of aluminum is relatively low, in this process, the efficiency and locality of induction heating are used to accurately heat the aluminum core 131 to the welding temperature, while not causing excessive heat to other parts of the copper-clad aluminum bar 13, such as the copper layer 132. Moreover, the copper layer 132 can be preheated while the aluminum core 131 is welded, and the intermetallic compound at the weld is less, with good mechanical properties and electrical conductivity.

[0040] After the aluminum core 131 is welded, the copper-clad aluminum bar 13 is spot welded by the laser welding head 6 under the precise control of the mechanical arm 12. The laser welding head 6 emits a high-energy-density laser beam that instantaneously melts the copper layer 132 on the surface of the copper-clad aluminum bar 13, causing the copper layer 132 at the butt joint to fuse together. The mechanical arm 12 can accurately move the laser welding head 6 to the position where spot welding is needed according to the preset path and parameters, and perform high-quality spot welding. The purpose of spot welding is to temporarily fix the welding position, ensuring that the position and butt joint state of the copper-clad aluminum bar 13 remain stable during the subsequent welding process, thereby ensuring the overall welding quality. After spot welding, the second displacement driving member 8 is first retracted to separate the output end of the second displacement driving member 8 from the transmission rod 81. At this time, the motor 3 is started, and the first clamp block 4 drives the copper-clad aluminum bar 13 and the second clamp block 7 to rotate, thereby continuing to weld the copper layer 132 at the butt joint position of the copper-clad aluminum bar 13 by the laser welding head 6. Thus, the welding and connection of the copper layer 132 and the aluminum core 131 are achieved.

[0041] The above embodiment combines electromagnetic induction brazing and laser welding technology to perform segmented welding on the aluminum core 131 and the copper layer 132, and applies pressure to the weld of the copper-clad aluminum bar 13 during induction brazing by the driving force of the second displacement driving member 8, thereby improving the welding quality and avoiding problems such as pores and insufficient joint strength that occur in traditional welding methods, ensuring the strength of the copper-clad aluminum bar 13 connection structure and reducing the resistance.

[0042] For example, referring to Figure 3 , the base 1 is fixedly provided with a second limiting block 52, and the second limiting block 52 is in abutting cooperation with the sliding block 53. The displacement range of the sliding block 53 is constrained, so that the sliding block 53 abuts against the second limiting block 52 in the non-working state, i.e., the sliding block 53 is located at the initial position.

[0043] For example, referring to Figure 3 , Figure 4 andFigure 5 The output end of the driving shaft 31 is provided with a mounting table 311, and the first clamping block 4 is provided with a mounting portion 411 away from one end of the clamping groove. The mounting portion 411 is designed in an integrated structure with the first clamping block 4, and the mounting table 311 of the driving shaft 31 is connected with a mounting groove 412 provided on the mounting portion 411.

[0044] The first clamping block 4 is threadedly connected with a clamping pin 41.

[0045] The mounting portion 411 is threadedly connected with a quick-change pin 42, and the quick-change pin 42 penetrates the mounting portion 411 and the mounting table 311.

[0046] In the above embodiment, during assembly, the worker only needs to align the mounting groove 412 on the mounting portion 411 with the mounting table 311 of the driving shaft 31 to quickly complete the preliminary positioning, so that the threaded hole of the quick-change pin 42 on the mounting portion 411 is quickly aligned with the threaded hole on the driving shaft 31, which facilitates the quick installation and disassembly of the mounting portion 411 from the driving shaft 31, greatly reduces the installation time of the first clamping block 4, reduces the assembly difficulty, and is simple to operate. When disassembled, the first clamping block 4 with different sizes of clamping grooves can be replaced, and the clamping grooves with different sizes correspond to copper-clad aluminum bars 13 with different cross-sectional sizes, so that the device can easily adapt to the welding needs of different types of copper-clad aluminum bars, such as copper-clad aluminum bars 13 with different thicknesses, widths or materials. By replacing the corresponding first clamping block 4, the versatility and flexibility of the equipment are improved. Similarly, the installation and disassembly principle of the second clamping block 7 on the transmission rod 81 is as above.

[0047] It should be noted that, in use, one copper-clad aluminum bar 13 is clamped and fixed on the first clamping block 4 and the second clamping block 7 by the clamping pin 41 respectively, then the first displacement driving member 10 is started to drive the sliding block 9 to slide along the first sliding rail 11 by a first distance, and then the second displacement driving member 8 is started to drive the second clamping block 7 to move the copper-clad aluminum bar 13 thereof towards the first clamping block 4 by a second distance by abutting and pushing the transmission rod 81 at the output end of the second displacement driving member 8, and the copper-clad aluminum bar 13 clamped by the first clamping block 4 is stationary, wherein the first distance is greater than the second distance.

[0048] At this time, the annular electromagnetic induction welding head 5 is sleeved outside the copper-clad aluminum bar 13, and under the sliding of the sliding block 53 along the second sliding rail 54, the butt joint position of the copper-clad aluminum bar 13 is located at the annular center of the electromagnetic induction welding head 5. After the electromagnetic induction welding head 5 is powered on, the aluminum cores 131 of the two copper-clad aluminum bars 13 are welded together. Then, after the electromagnetic induction welding head 5 is powered off, the laser welding head 6 precisely controls the copper-clad aluminum bar 13 to perform spot welding.

[0049] Then, the second displacement drive 8 is started to retreat, the output end of the second displacement drive 8 is separated from the transmission rod 81, at this time, the motor 3 is started, under the drive of the drive shaft 31, the first clamp block 4 drives the preliminarily butt-jointed copper-clad aluminum bar 13 and the second clamp block 7 to rotate, under the continuous welding of the laser welding head 6, the copper layer 132 at the butt-jointed position of the copper-clad aluminum bar 13 is welded for one round, thus, the welding connection of the copper layer 132 and the aluminum core 131 is realized;

[0050] It should be noted that after the welding is finished, the clamping pin 41 on the second clamp block 7 is disassembled first, the first linear displacement member retreats, the second clamp block 7 is separated from the workpiece, then the clamping pin 41 on the first clamp block 4 is disassembled, and the welded copper-clad aluminum bar 13 is smoothly taken off.

[0051] The above-mentioned embodiments only express several implementation manners of the present application, the description is more specific and detailed, but it cannot be understood as the limitation of the patent scope of the present application. It should be pointed out that, for the ordinary skilled in the art, under the premise of not departing from the present application concept, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
