As shown in fig. 1-2, an assembled template welding jig, includes frame 1 and a plurality of anchor clamps mechanism 2, 1 up end in frame is provided with two parallel guide rails 11, anchor clamps mechanism 2 side by side movable mounting is in 1 up end in frame, anchor clamps mechanism 2 includes slide 21, horizontal centre gripping subassembly 22 and vertical centre gripping subassembly 23, slide 21 with guide rail 11 activity joint, two vertical centre gripping subassembly 23 mirror symmetry is installed the both ends of slide 21, two horizontal centre gripping subassembly 22 mirror symmetry is installed the side portion of slide 21. Specifically, in this embodiment, the rack 1 is horizontally installed right below a welding robot (not shown in the figure), two parallel guide rails 11 are arranged on the upper end surface of the rack 1, the guide rails 11 are arranged along the length direction of the rack 1, and 7 fixture mechanisms 2 are installed on the rack 1 in parallel. In other embodiments, the number of the clamping mechanisms 2 can be other numbers, and can be set according to the size of the workpiece. The clamp mechanism 2 is movably mounted on the frame 1 and can be driven by an external force to displace along the guide rail 11, specifically, a lead screw, or an electric push rod, an air cylinder, or the like can be used to drive the clamp mechanism 2 to displace along the guide rail 11, which is not limited in this respect. The fixture mechanism 2 comprises a sliding plate 21, a transverse clamping assembly 22 and a longitudinal clamping assembly 23, wherein the sliding plate 21 is movably clamped with the guide rail 11, the sliding plate 21 is rectangular plate-shaped, 1 two longitudinal clamping assemblies 23 are arranged at two ends of the sliding plate 21 in mirror symmetry and used for clamping a workpiece along the length direction of the workpiece, and two transverse clamping assemblies 22 are arranged at the side edges of the sliding plate 21 in mirror symmetry and arranged at the left side edge of the sliding plate 21 in the embodiment, and can also be arranged at the right side edge of the sliding plate 21 in other embodiments as long as the workpiece can be clamped in two directions in one plane. And the position of the clamp mechanism 2 is adjustable, so that the clamp mechanism is convenient to match workpieces with different lengths, and is very convenient to use when clamping workpieces loaded on stairs. The fixture mechanism 2 in the technical scheme is detachably mounted on the rack 1, is designed in an assembled mode, is flexible to use, and can clamp workpieces in the transverse direction and the longitudinal direction simultaneously, so that the workpieces are prevented from being displaced in the welding process, and the welding quality is improved.

As shown in fig. 1-2, each of the transverse clamping assembly 22 and the longitudinal clamping assembly 23 includes a mounting bracket 221, an air cylinder 222 and a pressing rod 223, the mounting bracket 221 is vertically installed on the sliding plate 21, the air cylinder 222 is connected to a side of the mounting bracket 221 away from the sliding plate 21, the pressing rod 223 is movably connected to the top of the mounting bracket 221 through a pin, and an output end of the air cylinder 222 is connected to one end of the pressing rod 223 away from the sliding plate 21. Specifically, in this embodiment, before the workpiece is placed, the air cylinder 222 drives the pressing rod 223 to turn upwards and turn towards the side away from the sliding plate 21, so as to be in an open state, thereby preventing the pressing rod 223 from blocking the workpiece; after the work piece was placed on slide 21, cylinder 222 drive compression bar 223 resets, and compression bar 223's tip and work piece butt rely on the effort that cylinder 222 provided, can cooperate slide 21, press from both sides the work piece tight on horizontal and longitudinal direction, when avoiding the welding, the work slides, leads to the welding dislocation.
