Blade clamping device

Abstract

The invention belongs to the technical field of aircraft blade clamps, and particularly relates to a blade clamping device. The blade clamping device comprises a base, a screw rod, clamping blocks, Y-shaped chucks and an ejector rod assembly. The screw rod comprises a polished rod section and two threaded sections arranged at the two ends of the polished rod section correspondingly, the polished rod section and the two threaded sections are correspondingly arranged in a mounting groove of the base, and the polished rod section is clamped in the mounting groove through a positioning block, so that the screw rod can only rotate in the mounting groove; threaded holes are formed in the bottom ends of the clamping blocks, positioning grooves are formed in the top ends of the clamping blocks, and the two clamping blocks are oppositely arranged on the two threaded sections through the threaded holes in the bottom ends correspondingly; the two Y-shaped chucks are separately mounted in the positioning grooves of the corresponding clamping blocks; and a positioning seat of the ejector rod assembly is fixed to the base, a supporting rod is mounted on the positioning seat, the supporting rod is sleeved with a movable block in a sliding mode, and after the position of the movable block is adjusted, an ejector rod and the supporting rod are fixed through an adjusting nail. According to the blade clamping device, the non-working face of a blade is used for positioning, and data acquisition of the whole working face can be achieved.

[0002] When measuring or polishing the blade, it is necessary to clamp and fix the blade. Since the blade body of the blade is a thin-walled rotating surface, the blade body cannot be clamped. The tongue and groove part of the blade is a symmetrical curved surface, which is relatively thick and can be Clamping, but at the same time, the working surface of the tenon and groove is also the benchmark for measurement or processing. There are also shortcomings in using the working surface of the tenon and groove as the clamping positioning surface, which brings inconvenience to the measurement

[0003] Most of the existing blade clamping and tooling technologies use the working surface of the blade tenon and groove for clamping and positioning, and its disadvantages are: it is easy to cause damage to the blade working surface; different blades require different tooling, the cost is high and the fixture manufacturing period is long ;The structure is relatively complex, and the actual operation is more limited by space factors; for the measurement tasks with a large number of parts and large volume, the measurement process is not easy to adjust and the efficiency is low
