The utility model provides a kind of economizer tube bank welding auxiliary alignment device, it is related to welding auxiliary equipment technical field, including bottom plate, further include: alignment subassembly, alignment subassembly includes the support seat being connected on bottom plate, in the utility model, the pipe body to be welded is placed in predetermined position, the output end of pneumatic cylinder promotes clamping block movement, and one end of pipe body is clamped and fixed, ensure the stability of welding process, subsequently, sliding block on guide rod is slid to predetermined position, limit rod and expansion spring drive pressure block down, by the elastic action of expansion spring, the other end of pipe body is limited by pressure block, prevent its displacement in welding process, ensure that pipe mouth accurate level alignment, second transmission motor drives rotating wheel rotation, drive rotating plate to rotate on support block, so that pipe body is rotated, convenient for pipe body to be welded, realize pipe body accurate positioning, stable clamping and rotating adjustment, guarantee welding alignment precision and welding efficiency.

This application provides an automated pneumatic drilling machine, including a frame with a base platform mounted on it; a first transverse platform for providing movement in a first horizontal direction; a second transverse platform for providing movement in a second horizontal direction, with the first and second horizontal directions perpendicular to each other; and a pneumatic drilling assembly including a cylinder and a pneumatic drill bit, the pneumatic drilling assembly moving perpendicular to the base platform and used to drill a workpiece placed on the second transverse platform. The start and stop of the first and second transverse platforms and the pneumatic drilling assembly are all controlled by a PLC control module. This application features overload protection and impact resistance. The pneumatic system itself is compressible; when the drill bit encounters a hard point and gets stuck, the pneumatic cylinder or the pneumatic drill bit can instantly absorb the impact energy through internal pressure relief or "slippage," avoiding rigid damage to the transmission mechanism. The equipment is safer, has a longer service life, and the pneumatic system has a simple structure and low maintenance cost.

This utility model relates to the field of UAV relay device technology and discloses a distributed UAV signal relay sharing device, including a relay device. The relay device has an external disassembly mechanism and a heat dissipation mechanism. The disassembly mechanism includes a fixing frame with a groove on its top. A lead screw is rotatably connected to the inner side of the groove. A moving block is threadedly connected to the outer side of the lead screw. A positioning frame is fixedly connected to the top of the moving block. A threaded rod is rotatably connected to one end of the positioning frame. A fixing block is installed at the bottom of the threaded rod. A suction cup is installed at the bottom of the fixing block. A limiting rod is fixedly connected to one end of the fixing block. This distributed UAV signal relay sharing device, through the disassembly mechanism, allows for easy installation and fixing by simply rotating the threaded rod to detach the suction cup from the UAV, and then rotating the lead screw to detach the positioning frame from the UAV.
