Problems solved by technology

from figure 1 It can be seen that due to the structure of the special fixture, there are the following disadvantages: (1) One set of blade tenon root type fixtures of one size will inevitably lead to more fixtures and increase the processing cost; (2) The special fixture uses the back of the blade basin One side is a fixed reference, and the other side is compressed by a compression device. This solution will cause instability in the processing size of the blade profile due to the upper and lower deviations of the blade tenon size; (3) It takes a long time to debug when replacing the processed blade, which affects work efficiency

Embodiment 1

[0039] In this embodiment, the structure of the universal fixture for processing the profile of the blade is as follows: figure 2 , image 3 As shown, it includes a base 1, a self-centering two-jaw chuck, a blade tenon fixing seat 4, an adjustable positioning block 5 and a guide block 6. The structure of base 1 is as follows Figure 4 , Figure 5 As shown, it is a circular seat body, the seat body is provided with a central hole, and its periphery is provided with eight U-shaped grooves 13 equiangularly distributed, and its top surface is provided with a positioning protrusion for installing a self-centering two-jaw chuck. Table 14, the bottom surface of which is provided with grooves to reduce the contact surface with the blade profile processing equipment; the structure of the blade tenon fixing seat 4 is as follows Figure 6 , Figure 7 , Figure 8 As shown, the bottom surface is provided with a positioning structure for installation, and one side is provided with a j...

Embodiment 2

[0044] In this embodiment, the structure of the universal fixture for processing the profile of the blade is as follows: Figure 14 As shown, it includes a base 1 , a self-centering two-jaw chuck, a blade tenon fixing seat 4 , a block 18 , an adjustable positioning block 5 and a guide block 6 . The difference from Embodiment 1 is that two blocks 18 are added, and the two blocks are respectively installed on the sides of the two blade tenon fixing seats 4 facing the center of the self-centering two-jaw chuck body 3, and the two blocks are The provided jaws 12 are directed toward the center of the body 3 of the self-centering two-jaw chuck.

[0045] The universal jig for processing blade profiles described in this embodiment only needs to replace two blocks 18 instead of two blade tenon fixing seats 4 when the tenon root shape of the blade to be processed is changed.

Abstract

A general clamp for machining a blade molded line comprises a base, a self-centering two-claw chuck, blade tenon fixing bases, an adjustable locating block and a guiding block or a base, a self-centering two-claw chuck, blade tenon fixing bases, molded blocks, an adjustable locating block and a guiding block. The self-centering two-claw chuck is arranged on the base, the two blade tenon fixing bases are arranged two claw top faces of the self-centering two-claw chuck, and the two molded blocks are arranged on the lateral sides of the two blade tenon fixing bases facing the self-centering two-claw chuck body center. The adjustable locating block is arranged on a self-centering two-claw chuck body. The installing position of the adjustable locating block on the chuck body enables the center line of a strip groove to be perpendicular to the center line of the two claws. The guiding block is arranged on the self-centering two-claw chuck body, and a guiding face of the guiding block is in contact with the lateral side of the adjustable locating block.

Description

technical field [0001] The invention belongs to the field of fixtures, in particular to a universal fixture for processing blade profiles. Background technique [0002] The blade is an indispensable part of the engine, gas turbine, fan and other equipment. The traditional blade profile processing fixture is a special fixture designed according to the shape and size of the tenon of the blade, that is, a set of fixtures is designed for a tenon root blade of one size. The structure of the traditional blade profile processing fixture is as follows: figure 1 shown. From figure 1 It can be seen that due to the structure of the special fixture, there are the following disadvantages: (1) One set of blade tenon root type fixtures of one size will inevitably lead to more fixtures and increase the processing cost; (2) The special fixture uses the back of the blade basin One side is a fixed reference, and the other side is compressed by a compression device. This solution will cause ...
