[0035] Working principle and usage process of the present invention: During use, the two components (referred to as workpieces) that need to be welded with the tool are respectively inserted between the adjustable clamping plate 65 and the limit clamping plate 67 of the two limit clamping mechanisms 6. The workpieces are butted, and then the second height adjustment member 64 is controlled to extend so that the adjustable clamping plate 65 moves downward to cooperate with the limit clamping plate 67 to clamp and fix the workpieces. Then, the user welds the workpieces through a welding device (the use of the welding device is prior art);

[0036] During the welding process, if the posture of the workpiece needs to be adjusted, the user can rotate the limit mounting cylinder 61. At this time, the two limit mounting cylinders 61 drive the workpiece to rotate together, so as to facilitate the user to turn over the workpiece and achieve the first-level posture adjustment of the workpiece. Secondly, the user can control the first telescopic braking member 221 to contract to release the limit fixation of the adjustable support ball 224. At this time, the second limit support plate 4 can rotate horizontally along the adjustable lifting cylinder 23. At this time, the workpiece rotates horizontally with the second limit support plate 4 to achieve the second-level posture adjustment of the workpiece;

[0037] Secondly, control the first height adjustment member 21 to move downward to make the adjustable lifting cylinder 23 move downward. At this time, the second limit support plate 4 can shake its head under the combined action of the limit support base 222 and the adjustable support ball 224, so that the orientation and inclination angle of the second limit support plate 4 both change, achieving the third-level posture adjustment of the workpiece. In addition, control the second telescopic braking member 227 to contract to release its fixing effect. At this time, the user can perform secondary adjustment on the orientation and inclination angle of the second limit support plate 4 to achieve the fourth-level posture adjustment of the workpiece;

[0038] Thus, through the mutual cooperation of multiple structures, the user can, through simple control, realize the arbitrary adjustment of the workpiece posture through the mutual cooperation of the first-level posture adjustment, the second-level posture adjustment, the third-level posture adjustment, and the fourth-level posture adjustment. For the user, through simple unlocking, he can pull the second limit support plate 4 according to experience to quickly adjust the target posture of the workpiece;

[0039] Thus, through the mutual cooperation of multiple structures, the user can arbitrarily adjust the posture of the tool according to work experience during the welding process, and the user can quickly adjust the tool to the target posture through the positioning clamping device, so that the user can better perform subsequent welding on the tool, making the use of the positioning clamping device more convenient. Secondly, the present invention can be applied to the processing of tools of different models, making the applicable range of the positioning clamping device wider. In addition, the present invention has a simple structure and is easy to use, and is worthy of popularization and use.
