A fast and precise positioning device and positioning method for a blade

Abstract

The invention discloses a rapid precise positioning device and method of a blade and belongs to the technical field of aircraft engines. The rapid precise positioning device comprises a vertically-arranged baseplate, a square box positioning mechanism and a positioning square box mechanism are arranged on the baseplate. The square box positioning mechanism is composed of a square box provided with horizontally-formed through holes, a forcing screw and three positioning screws. The positioning square box mechanism comprises a support, an upper support, a lower positioning seat, a left positioning block and a right positioning block. The positioning method by adopting the rapid and precise positioning device includes the steps of positioning of the blade in the positioning square box mechanism; positioning of the square box positioning mechanism; positioning of the blade in a square box positioning device; taking out of the positioned blade for processing. Therefore, the blade can be rapidly and precisely positioned, processing quality of a blade boss is guaranteed, efficiency of processing the blade boss is improved, utilization rate of a processing device is improved, and time for mounting and demounting the positioning device is saved.

Description

technical field [0001] The invention belongs to the technical field of aero-engines, in particular to a fast and precise positioning device and positioning method for blades. Background technique [0002] The structure and method of use of the positioning device directly affect the efficiency of wire cutting. Usually, wire cutting requires one positioning for one profile, and repositioning is required for different profiles of the same part. Different positioning is required to adapt to different profiles during repositioning. device, which increases the cost of the positioning device, and each positioning also causes a waste of resources for a long downtime of the processing equipment. [0003] The existing method of cutting and processing the sides of the bosses at both ends of small blades is as follows: first install a blade on the positioning device, then install the blade together with the positioning device on the processing equipment, align, cut, and complete the pro...

[0002] The structure and method of use of the positioning device directly affect the efficiency of wire cutting. Usually, wire cutting requires one positioning for one profile, and repositioning is required for different profiles of the same part. Different positioning is required to adapt to different profiles during repositioning. device, which increases the cost of the positioning device, and each positioning also causes a waste of resources for a long downtime of the processing equipment

[0003] The existing method of cutting and processing the sides of the bosses at both ends of small blades is as follows: first install a blade on the positioning device, then install the blade together with the positioning device on the processing equipment, align, cut, and complete the processing of a boss of the blade One side of the blade; after processing, stop the machine and remove the blade, then install the blade on another positioning device, install the blade together with the positioning device on the processing equipment, align, cut, and complete the processing of the same boss of the blade The other side is repeated until all the sides of the bosses at both ends of the blade are processed; this positioning and processing method increases the cost of the positioning device, makes the processing equipment stop for a long time, the utilization rate is low, and the processing efficiency is low. Therefore, the design of a A fast and precise positioning device and positioning method for blades that can reduce the cost of positioning devices and shorten the downtime of processing equipment have become the key to solving the problem
