[0046] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0047] This application provides an ultrasonic copper-aluminum busbar welding positioning fixture, as shown in the reference. Figures 1 to 3The ultrasonic copper-aluminum busbar welding positioning fixture includes a fixture body 1, and a workpiece placement platform 2, a first end face positioning fixture 3, a first clamping fixture 4, a second end face positioning fixture 5, and a second clamping fixture 6, all mounted on the fixture body 1. When welding a first workpiece W1 and a second workpiece W2, the first workpiece W1 and the second workpiece W2 are placed on the workpiece placement platform 2 respectively. The first workpiece W1 is positioned and fixed by adjusting the first end face positioning fixture 3 and the first clamping fixture 4, and the second workpiece W2 is positioned and fixed by adjusting the second end face positioning fixture 5 and the second clamping fixture 6. This reduces the possibility of the first workpiece W1 and the second workpiece W2 shifting during the welding process and ensures the welding effect. The first workpiece W1 is an aluminum busbar, and the second workpiece W2 is a soft copper busbar.
[0048] Furthermore, refer to Figure 3 The workpiece placement stage 2 includes a first placement stage 21 and a second placement stage 22 mounted on the upper surface of the fixture body 1, and a welding placement stage 23 connected to the fixture body 1. The first placement stage 21, the welding placement stage 23, and the second placement stage 22 are distributed sequentially along a first direction. The first placement stage 21 is provided with a receiving groove 211 for placing a first workpiece W1, and the second placement stage 22 is bolted with a baffle 221 for abutting the end of a second workpiece W2. After the first workpiece W1 and the second workpiece W2 are placed in position, one end of the first workpiece W1 is placed on the welding placement stage 23, and the end of the second workpiece W2 away from the baffle 221 is placed on the end of the first workpiece W1, awaiting welding.
[0049] Furthermore, refer to Figure 2 and Figure 3 Two sets of first end-face positioning fixtures 3 are arranged opposite each other on the upper surface of the fixture body 1, and the two sets of first end-face positioning fixtures 3 are respectively located on both sides of the second placement table 22. Each set of first end-face positioning fixtures 3 includes a first base 31, a first clamping member 32, and a first driving member 33. The first base 31 is bolted to the upper surface of the fixture body 1, and the upper surface of the first base 31 has a sliding groove along a second direction perpendicular to the first direction. The bottom of the first clamping member 32 slides in the sliding groove, and the clamping end of the first clamping member 32 is positioned facing the end of the first workpiece W1 located on the welding placement table 23. The first driving member 33 is used to drive the first clamping member 32 to move in the second direction, thereby clamping or releasing the first workpiece W1.
[0050] Reference Figure 3 In this embodiment of the application, the first driving member 33 includes a driving screw that is arranged in a horizontal second direction and threadedly connected to the first base 31. One end of the driving screw is rotatably connected to the first clamping member 32 through a bearing, and the other end is connected to a knob. By rotating the knob, the first clamping member 32 can be moved along the second direction.
[0051] Furthermore, refer to Figure 1 and Figure 4 The first clamping fixture 4 includes a vertical quick clamp 41. By moving the handle of the quick clamp 41, the chuck of the quick clamp 41 can press down on the upper surface of the first workpiece W1 or lift up.
[0052] Furthermore, refer to Figure 1 and Figure 4 Two sets of second end-face positioning fixtures 5 are arranged opposite each other on the upper surface of the fixture body 1, and the two sets of second end-face positioning fixtures 5 are located on both sides of the workpiece placement table 2. Each set of second end-face positioning fixtures 5 includes a second base 51, a second clamping member 52, and a second driving member 53. The second base 51 is bolted to the upper surface of the fixture body 1, and the bottom of the second clamping member 52 is located on the upper surface of the second base 51 and connected to the second driving member 53. The clamping end of the second clamping member 52 is positioned towards the end of the second workpiece W2 located above the welding placement table 23. Under the drive of the second driving member 53, the second clamping member 52 can loosen or clamp the end of the second workpiece W2.
[0053] Furthermore, refer to Figure 4 The second driving component 53 includes a driving cylinder 531 bolted to the upper surface of the second base 51. The telescopic rod of the driving cylinder 531 is arranged along the second direction and faces the second workpiece W2. The end of the telescopic rod of the driving cylinder 531 is connected to the bottom of the second clamping component 52. Driven by the telescopic rod of the driving cylinder 531, the second clamping component 52 can loosen or clamp the end of the second workpiece W2.
[0054] Furthermore, refer to Figure 1 and Figure 4 A pair of guide rods 54 are provided on the second base 51 along the second direction. The guide rods 54 pass through the bottom of the second clamping member 52, and the second clamping member 52 slides with the guide rods 54. During the process of the drive cylinder 531 driving the second clamping member 52 to move, the guide rods 54 play a guiding role, reducing the possibility of the second clamping member 52 shifting or shaking.
[0055] Furthermore, refer to Figure 1The second clamping fixture 6 includes a mounting plate 61, a rotating rod 62, and a vertical drive component 63. The mounting plate 61 is mounted on the upper surface of the fixture body 1. The rotating rod 62 is hinged to the upper surface of the mounting plate 61 via a hinge seat and can rotate along a vertical plane. The upper end of the rotating rod 62 is hinged to the hinge seat, and the lower end of the hinge seat is hinged to the upper surface of the mounting plate 61. One end of the rotating rod 62 is connected to a clamping component 64 for clamping the second workpiece W2, and the other end is hinged to the vertical drive component 63. The vertical drive component 63 includes a vertically arranged second cylinder 631. The cylinder body of the second cylinder 631 is bolted to the mounting plate 61, and the telescopic rod of the second cylinder 631 is vertically upward and hinged to the end of the rotating rod 62 away from the clamping component 64. When the telescopic rod of the second cylinder 631 extends, the end of the rotating rod 62 connected to the telescopic rod of the second cylinder 631 rises, and the end connected to the pressing component 64 falls, thereby pressing the second workpiece W2.
[0056] This application provides an ultrasonic copper-aluminum busbar welding positioning fixture. It consists of a fixture body 1, on which a workpiece placement platform 2, a first end-face positioning fixture 3, a first clamping fixture 4, a second end-face positioning fixture 5, and a second clamping fixture 6 are mounted. When welding a first workpiece W1 and a second workpiece W2 together, the first workpiece W1 and the second workpiece W2 are placed sequentially on the workpiece placement platform 2. The first end-face positioning fixture 3 and the first clamping fixture 4 are adjusted to fix the first workpiece W1, and the second end-face positioning fixture 5 and the second clamping fixture 6 are adjusted to fix the second workpiece W2. This reduces the possibility of the first workpiece W1 and the second workpiece W2 shifting during welding, ensuring the welding effect.
