[0017] Compared with the prior art, the beneficial effects of this utility model are: this automatic dust collection welding fixture allows for rapid workpiece fixing by rotating the handle, avoiding the need for multiple sets of cylinders to position the workpiece, improving workpiece positioning efficiency, facilitating operation, and enhancing practicality. The specific details are as follows:

[0018] 1. When positioning a workpiece for laser welding, the workpiece is placed on top of two support plates. Then, the rotating rod is turned by the handle, which in turn causes the rotating frame to rotate. The rotation of the rotating frame can pull the connecting frame to rotate via the connecting rod. At the same time, the rotating frame can drive the rotating frame to rotate via the push rod, causing the two rotating shafts to rotate. The rotation of the rotating shafts drives the column block to rotate in a circle. After the column block rotates in a circle, it can drive the strip plate to move through the sliding connection with the movable groove on the strip plate, which in turn causes the moving frame to move. At the same time, the moving frame moves, causing the movable block to slide on the support guide rail, so that the two positioning plates can come close together to clamp and position the workpiece. Thus, the workpiece can be positioned by turning the handle alone, which can achieve rapid fixation of the workpiece. Alternatively, a cylinder can be added to drive the handle to rotate, which can achieve rapid positioning of the workpiece with a single cylinder, avoiding the need to use multiple sets of cylinders to position the workpiece, improving the efficiency of workpiece positioning, simplifying operation, and enhancing practicality.

[0019] 2. When fixing the workpiece, the rotation of one side of the rotating shaft can drive the rotating shaft to rotate through the meshing of the driving gear and the driven gear. After the rotating shaft rotates, the movable frame can rotate, and then the movable frame and the movable rod pull the connecting column to move. This allows the L-shaped frame to move through the connecting column, so that the movable plate can slide on the fixed guide rail. This allows the cover to move directly above the workpiece. The extraction slot at the bottom of the cover is located above the workpiece. The installation pipe is connected to an external air purification device through a pipeline. When welding the workpiece, air is extracted from the inside of the cover through the installation pipe. The fumes generated during the welding process can enter the cover, allowing for the collection and purification of the welding fumes. The position of the fume extraction can be automatically adjusted by positioning the workpiece, improving practicality. Attached Figure Description

[0031] Working principle: Before using this type of automatic dust collection welding fixture, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 7As shown, when positioning the workpiece for laser welding, the workpiece is placed on top of two support plates 103. Then, the rotating rod 107 is rotated by the handle 108, which in turn causes the rotating frame 109 to rotate. The rotation of the rotating frame 109 can pull the connecting frame 112 to rotate via the connecting rod 110. At the same time, the rotation of the connecting frame 112 can drive the rotating frame 113 to rotate via the push rod 114, causing the two rotating shafts 111 to rotate. The rotation of the rotating shafts 111 can drive the column block 122 to rotate in a circular motion. After the column block 122 rotates in a circular motion, it can move through the movable groove 127 on the strip plate 126. The sliding connection drives the strip plate 126 to move, which in turn causes the moving frame 124 to move. As the moving frame 124 moves, the movable block 128 slides on the support guide rail 129, which allows the two positioning plates 125 to come close together to clamp and position the workpiece. Thus, the workpiece can be positioned by simply rotating the handle 108, which can achieve quick fixation of the workpiece. Alternatively, a cylinder can be added to drive the handle 108 to rotate, which can achieve quick positioning of the workpiece with a single cylinder, avoiding the need to use multiple sets of cylinders to position the workpiece, improving the efficiency of workpiece positioning, facilitating operation, and enhancing practicality.

[0032] When fixing the workpiece, the rotation of one side of the rotating shaft 111 can drive the rotating shaft 115 to rotate through the meshing of the driving gear 116 and the driven gear 117. After the rotating shaft 115 rotates, the movable frame 118 can rotate, and then the movable frame 118 and the movable rod 119 can pull the connecting column 120 to move, so that the connecting column 120 can drive the L-shaped frame 132 to move, so that the moving plate 131 can slide on the fixed guide rail 130, and then the cover 134 can move directly above the workpiece. The extraction slot at the bottom of the cover 134 is located above the workpiece. The installation pipe 135 is connected to an external air purification device through the pipe. When welding the workpiece, the air is extracted from the inside of the cover 134 through the installation pipe 135. The fumes generated during the welding process can enter the cover 134, so that the fumes generated during welding can be collected and purified. The position of the fume extraction can be automatically adjusted by positioning the workpiece, which improves practicality.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
