Problems solved by technology

[0003] In the prior art, the angular fixation of the blade is usually tightened by two screws at both ends of the blade journal. This positioning method relies on the operator's vision and sense, and cannot accurately fix the angular rotation of the blade. It is easy to produce angular deviation, and it is easy to cause the blade to be pushed up and deflected, causing the blade to be pushed up and deflected; the axial positioning structure of the blade in the prior art is only suitable for fixed-type blades, and this positioning support can only Satisfies one type of blade, but also cannot satisfy the positioning of multi-stage blades

Embodiment Construction

[0017] Such as figure 1 or figure 2 The shown multi-level universal angular self-adaptive blade three-coordinate measuring clamp base includes a base 1. A fixed top base 2 is provided on one side above the base 1. The fixed top base 2 is fixedly connected to the base 1, and the other A linear slide rail 3 fixedly connected to the base 1 is arranged along the axial direction of the blade 10. A sliding center seat 4 is arranged above the linear slide rail 3, wherein the first center of the fixed center seat 2 is connected to the sliding center The axis of the second center in the seat 4 is on the same straight line, and the sliding top seat 2 can move along the axial direction of the blade 10 by using the linear slide 3 to cooperate with the slideway provided at the bottom of the sliding center seat 4; Brackets 5 with limit holes are arranged on both sides of the linear slide 3, and at least one limit hole is provided on the bracket 5. The setting of multiple limit holes is to ad...

Abstract

The invention relates to a multistage general angle self-adaptive blade three-coordinate measuring holder. Height concentric finial structures at the two sides of the holder are ejected into the finial holes at the two ends of a blade for realizing precision positioning of the center line of the blade; a finial at one side is installed on a linear guide rail, the precision slide performance of the linear guide rail is utilized, and a spring pin structure is designed on the slide guide rail to cooperate with the limiting hole in a base for realizing center positioning of blades with different lengths; and a fixed finial mechanism at the other side is provided with a chute and draw frame structure, the design structure utilizes the precision cooperation between a chute and a draw frame in theoretical angles, the upper portion of the draw frame is provided with a screwing screw, when the screw is screwed tight, the two sides of the draw frame are close to an inner side, and when the angle positioning surface portion of the blade is placed at the draw frame position and the screw is screwed, the draw frame is automatically attached to the blade angle positioning surface so that the blade angle self-adaptive positioning is realized, and thus the blade three-coordinate measuring precision and efficiency are improved.

Description

Technical field [0001] The invention relates to a fixing device, in particular to a multi-stage universal angular self-adapting blade three-coordinate measuring holder suitable for engine blades. Background technique [0002] At present, when inspecting the profile of engine blades, a fixing device is required to fix the blade position, and the fixing of the blade requires positioning of the journal direction of the blade and the angular direction of the blade, thereby limiting the journal of the blade Directional movement and angular rotation of the blades. [0003] In the prior art, the angular fixation of the blade usually uses two screws at both ends of the blade journal to tighten in both directions. This positioning method relies on the operator’s vision and senses and cannot accurately fix the angular rotation of the blade. It is easy to produce angular deviation, and it is easy to cause the blade to be deflected, and the blade is damaged and deflected; the axial positionin...
