[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. During welding, additional assembly fixtures are generally required, or pre-connection is performed using weld point assembly methods before using a suitable welding robot for final welding.

[0003] The existing assembly tooling relies entirely on manual positioning, resulting in poor positioning, low welding efficiency, and unreliable welding quality.

Figure 1 , Figure 2 and Figure 3 As shown, the base 1 includes a base plate and profiles installed below the base plate. The profiles are arranged in an alternating pattern to enhance the structural strength of the base 1. The base plate is roughly rectangular and is used to install the positioning and clamping structure 3. The profiles are connected to the turntable 2 and are located approximately at the center of the base 1. Specifically, the turntable 2 includes a turntable 21 connected to the positioner, a connecting plate 22 connected to the base 1, and a connecting frame 23 arranged between the turntable 21 and the connecting plate 22. Threaded holes are provided on the outer circumference of the turntable 21, and the turntable 21 is fixedly connected to the positioner by bolts. The connecting plate 22 is fixedly connected to the base 1 by welding or bolting. The connecting frame 23 is arranged in a crisscross pattern to enhance the connection stability between the turntable 2 and the base 1.

[0022] See also Figure 1 and Figure 2 The positioning and clamping structure 3 is mounted on the base 1. In one or more embodiments, the positioning and clamping structure 3 includes a positioning block 31 mounted on the base 1, an adjustable abutment block 32 mounted on the base 1, a bottom support block 33 mounted on the base 1, and a pressure plate 34 abutting above the workpiece. Specifically, multiple positioning blocks 31 are provided and are mounted on the base 1 by bolts. Figure 1As shown, the positioning block 31 is located near the left and lower sides of the base 1. For example, four positioning blocks 31 are provided, one near the left side of the base 1 (end block); the other three are near the lower side of the base 1 and spaced apart along the length of the base 1 (side blocks). Further, an adjustment structure is provided on the base 1, and the abutment block 32 is adjustablely mounted on the adjustment structure. Multiple abutment blocks 32 are provided, and correspondingly multiple sets of adjustment structures are provided. One abutment block 32 is mounted on one set of corresponding adjustment structures.

In one or more embodiments, the bottom support blocks 33 are arranged in two rows along the width direction of the base 1, with multiple blocks in each row. For example, each row has four bottom support blocks 33, which are fixed to the base 1 by bolts. The top of the bottom support blocks 33 abuts against the workpiece, supporting it and allowing the workpiece to be suspended above the base 1. Alternatively, each row of base 1 can have two, three, or other suitable numbers. Further, adjusting bolts 39 are threaded onto the base 1, and pressure plates 34 are rotatably mounted on the adjusting bolts 39. Specifically, each pressure plate 34 corresponds to two adjusting bolts 39, which fix the pressure plate 34 and prevent it from rotating during clamping. For example, six sets of pressure plates 34 are provided, with four sets near the four corners of the base 1 and the other two sets located at the upper middle and lower middle, respectively.
