Description

Technical Field

[0001] This utility model belongs to the field of welding fixture technology, and specifically relates to an automatic welding fixture. Background Technology

[0002] Welding, as a fundamental process in modern manufacturing, is widely used in numerous fields such as automobile manufacturing, aerospace, and rail transportation. With the continuous improvement of industrial automation, traditional manual welding is gradually being replaced by automated welding equipment. In automated welding, the fixture, as the core component for positioning and fixing the workpiece, directly affects welding accuracy, efficiency, and the yield rate of finished products.

[0003] When welding tubular parts, the tubular parts need to be rotated inside the automatic welding fixture. However, when the tubular parts rotate, the center line of the tubular parts deviates from the center line of the welding fixture, causing displacement between the welding point and the welding device.

[0021] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "page", "bottom", "inner", "outer", "clockwise", "counterclockwise", "coaxial", "bottom", "one end", "top", "other end", "one side", "front", "both ends", "both sides", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Referring now to the accompanying drawings, the various figures are intended only to illustrate certain exemplary embodiments and are not intended to limit the scope of the invention. In the various figures, the same reference numerals denote the same or corresponding parts. The dimensions and scales in the various figures are also for illustrative purposes only and should not be construed as limiting the scope of the invention; these dimensions may be enlarged relative to actual products.

[0025] Reference Figure 1-3An automatic welding fixture, as shown, includes a support frame 1. Second side strips 9 are provided on both sides of the support frame 1. A feeding tube 12 is provided at one end of each second side strip 9. An inflatable ring 13 is rotatably connected inside the feeding tube 12. First drive wheels 14 are provided at both ends of the feeding tube 12. A positioning hole 10 is provided inside the second side strip 9. A pipe rotation structure 11 is slidably connected to the outer wall of the second side strip 9. A tubular part is inserted into the feeding tube 12, and the tubular part is aligned with the first drive wheel 14. Then, the first drive wheel 14 is activated, causing the tubular part to move forward. An externally provided air pump inflates the inflatable ring 13, causing the inflatable ring 13 to collide and fix the tubular part.

[0026] Furthermore, in the above technical solution, the front and rear outer walls of the support frame 1 are provided with first side strips 2. One end of the first side strip 2 is provided with a sliding hole 3. A grinding structure is provided inside the sliding hole 3. The grinding structure includes a sliding rod 4, which is slidably connected inside the sliding hole 3. A return spring 5 is provided between the sliding rod 4 and the first side strip 2. One end of the sliding rod 4 is provided with a connecting block 6. A servo motor 7 is provided on the outer wall of the connecting block 6. A grinding wheel 8 is provided at the output end of the servo motor 7. During the welding of the tubular parts, the return spring 5 pushes the sliding rod 4 into the welding surface between the two tubular parts to start the servo motor 7. The servo motor 7 drives the grinding wheel 8 to rotate, and the grinding wheel 8 grinds the welding surface. At the same time, another set of grinding wheels 8 is pushed outward by the welding point and also starts the servo motor 7. The servo motor 7 drives the grinding wheel 8 to rotate, so that the grinding wheel 8 grinds the welding point.

[0027] Furthermore, in the above technical solution, the pipe rotation structure 11 includes a movable frame 1101. The movable frame 1101 has a guide hole 1102 inside, which is slidably connected to the second side strip 9. The top of the movable frame 1101 has a pin hole 1103, inside which a pin body 1104 is disposed. The bottom of the movable frame 1101 has a material discharge ring 1105. The bottom of the movable frame 1101 also has a mounting hole 1106, inside which a spring telescopic rod 1107 is disposed. One end of the spring telescopic rod 1107 has a lifting block 1108, and the lifting block 1108 is rotatably connected to a second drive wheel 1109. Two movable frames 1101 are provided, symmetrically distributed on both sides of the support frame 1. After the air ring 13 separates from the tubular part, the second drive wheel 1109 is activated, which drives the tubular part to rotate and adjust the welding position. At the same time, the spring telescopic rod 1107 pushes the lifting block 1108 downward, so that the lifting block 1108 drives the second drive wheel 1109 to always be in contact with the outer wall of the tubular part. Simultaneously, the movable frame 1101 is moved, and the movable frame 1101 slides on the second side strip 9 to adjust the position of the movable frame 1101. After the adjustment is completed, the pin body 1104 is inserted into the pin hole 1103 and the positioning hole 10 to fix the movable frame 1101.

[0028] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
