Alignment Tooling and Alignment Method for Multiple Crankshafts of Hybrid Fiber Multiaxial Warp Knitting Machine

Abstract

The invention relates to the technical field of crankshaft centering, in particular to a multi-crankshaft centering tool of a hybrid fiber multiaxial warp knitting machine and a centering method. The centering tool comprises a crankshaft; and the crankshaft is provided with a main shaft neck and a connecting rod shaft neck. The centering tool further comprises a flat plate, a V block, a spiral lifting device, an adjuster, an L-shaped adjusting block, a horizontal plate and a coupling; the V block is placed on the flat plate; the main shaft neck is placed on the V block; the spiral lifting device is placed on the flat plate rightly below the connecting rod shaft neck; the connecting rod shaft neck is fixedly provided with the adjuster through bolt connection; and the L-shaped adjusting block is horizontally and fixedly mounted on the adjuster through bolt connection. In consideration of difficult guarantee of the machining precision and the matching precision of a key slot and a flat key, the centering tool improves the crankshaft assembly precision, naturally solves the crankshaft dynamic balance problem caused by introduction of the key slot and the flat key, and reduces the machining cost.

Description

technical field [0001] The invention relates to the technical field of crankshaft alignment, in particular to a multi-crankshaft alignment tool and alignment method for a hybrid fiber multiaxial warp knitting machine. Background technique [0002] The hybrid fiber multi-axial warp knitting machine is to lay different fibers such as carbon fiber and glass fiber into several fiber layers according to different angles, and then use the warp knitting machine to "bind all the fiber layers into cloth", cut them, and use the RTM process Made of composite materials. [0003] For the consideration of cost and efficiency, the size of the fiber layer is relatively large, and correspondingly, the crankshaft of the warp knitting machine is designed to be very long. Such a slender crankshaft is extremely difficult to manufacture and assemble. Generally all be to make a plurality of identical short crankshafts now, then assemble into a long crankshaft in combination. Such as figure 1 ....
