An octagonal pipe gripper

Abstract

The invention relates to the field of conveying equipment and provides an octagonal tube tong. The octagonal tube tong comprises a tong connecting plate, an octagonal tube main frame and a plurality of grasping units. The octagonal tube main frame is mounted on the tong connecting plate and the grasping units are fixed on the octagonal tube main frame respectively. The grasping units comprise circular tubes, clamping cylinders, pressing arms, pressing blocks, fixing blocks, fixing walls and cylinder connecting parts. The circular tubes are connected with the octagonal tube main frame and fixedly connected with cylinder bodies of the clamping cylinders by the cylinder connecting parts. Piston rods of the clamping cylinders are connected with the pressing arms and the pressing blocks are fixed at the other ends of the pressing arms. The fixing walls are arranged on the cylinder connecting parts and the fixing blocks corresponding to the pressing blocks are arranged on the fixing walls. When the piston rods of the clamping cylinders protrude, the pressing blocks and the fixing blocks can cooperate to clamp a workpiece. The octagonal tube tong is capable of grasping the workpiece, convenient to install, adjust and disassemble and capable of improving the stability and the safety of equipment.

Description

technical field [0001] The invention relates to the field of conveying equipment, in particular to an octagonal pipe grip used on conveying equipment. Background technique [0002] The conveying equipment is a material handling equipment that continuously conveys materials on a certain aluminum alloy track. The conveying equipment can carry out horizontal, inclined and vertical conveying, and can also convey along the space route. The conveying equipment has a large conveying capacity and a long transportation distance, saving labor, time and effort, and saving labor costs quickly and efficiently. [0003] The gripper is an important part of the conveying equipment to grab the workpiece. It mainly clamps the workpiece, and realizes the release and clamping of the gripper through air circuit control. At present, the grippers on the automobile welding production line are mostly welded by steel plates, round pipes, square pipes, etc. when assembled. The disadvantage is that th...
