Abstract

A microscope bracket for blade fatigue vibration test belongs to the technical field of aero engine blade. The microscope bracket comprises the following components: magnetic bases, sleeves, columns and a microscope mounting arm. The magnetic bases are fixedly connected with one end of each column. The sleeves are sleeved on the columns. A clearance is kept between each sleeve and each column. Locking bolts are arranged on each sleeve. One end of the microscope mounting arm is fixedly connected with the sleeve. Two magnetic bases, two sleeves and two columns are arranged. The two sleeves are fixedly connected through connecting frames. The microscope bracket can be directly fixed on the tabletop of a vibrating platform through the magnetic bases. A problem of unsuitability of the prior microscope bracket for middle-size and large-size vibrating platform is settled. Furthermore the applicability of the microscope bracket is improved. Furthermore the microscope bracket has the following advantages: small volume, small weight and convenient movement.

Description

A kind of microscope stand for the test of blade Fatigue Vibration
Technical field
The utility model belongs to blade of aviation engine manufacturing technology field, particularly relates to a kind of microscope stand for the test of blade Fatigue Vibration.
Background technology
The workmanship of blade of aviation engine has directly determined the final performance of engine, in order to obtain qualified blade and to guarantee that blade works reliably in engine, in the research and production process of blade, with regard to needs, constantly blade is carried out to every test, the Fatigue Vibration test of its Leaf is important one, in the test of blade Fatigue Vibration, an important step is that blade is carried out to amplitude and stress demarcation.
By microscope, reading blade amplitude is the key that stress is demarcated, microscope is all fixed on and on microscope stand, reads blade amplitude, but existing microscope stand be all placed in ground, and be only applicable to small vibrating platform, for in, large vibration table, microscope cannot carry out reading of blade amplitude near blade by microscope stand, and the test of blade Fatigue Vibration cannot be gone on.Not only volume is large, quality heavy for existing microscope stand, mobile inconvenience and poor for applicability.
Utility model content
The problem existing for prior art, the utility model provides that a kind of volume is little, quality light, conveniently moving and the strong microscope stand for the test of blade Fatigue Vibration of applicability.
To achieve these goals, the utility model adopts following technical scheme: a kind of microscope stand for the test of blade Fatigue Vibration, comprise magnetic bases, sleeve, column and microscope installation support arm, one end Joint of described magnetic bases and column, described sleeve set is on column, between sleeve and column, leave gap, on sleeve, be provided with clamping screw; One end that described microscope is installed support arm is fixed on sleeve.
Described magnetic bases, sleeve and column are two covers, between two sleeves, by link, are fixedly connected with.
The beneficial effects of the utility model:
The utility model compared with prior art, can directly be fixed on vibration table surface by magnetic bases, having solved existing microscope stand cannot strengthen applicability of the present utility model for the situation of, large vibration table, and the utility model volume is little, quality light, conveniently moving.
Accompanying drawing explanation
Fig. 1 is a kind of microscope stand structural representation for the test of blade Fatigue Vibration of the present utility model;
Fig. 2 is the utility model and the shaking table structural representation while being used in conjunction with;
In figure, 1-magnetic bases, 2-sleeve, 3-column, 4-microscope is installed support arm, 5-link, 6-microscope, 7-blade, 8-fixture, 9-vibration table surface, 10-clamping screw.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of microscope stand for the test of blade Fatigue Vibration, comprise magnetic bases 1, sleeve 2, column 3 and microscope installation support arm 4, one end Joint of described magnetic bases 1 and column 3, described sleeve 2 is sleeved on column 3, between sleeve 2 and column 3, leave gap, on sleeve 2, be provided with clamping screw 10; One end that described microscope is installed support arm 4 is fixed on sleeve 2.
Described magnetic bases 1, sleeve 2 and column 3 are two covers, between two sleeves 2, by link 5, are fixedly connected with.
Below in conjunction with accompanying drawing, a use procedure of the present utility model is described:
As shown in Figure 2, before carrying out the test of blade Fatigue Vibration, choose corresponding fixture 8 clamping blades 7, by fixture 8, blade 7 is fixed to clamp on vibration table surface 9; Installation microscope support, microscope stand is adsorbed in by magnetic bases 1 on the mounting edge of vibration table surface, and sleeve 2 is moved to correct position, and by clamping screw 10, sleeve 2 is fixed on column 3; Microscope 6 is fixed to microscope to be installed on support arm 4, fine setting clamping screw 10 moving sleeve 2, finely tune microscope 6 and microscope simultaneously the link position of support arm 4 is installed, make operator just can in microscope 6, see the luminous point at blade tip place, Vibration on Start-up platform, adjust vibration frequency, and find out the maximum stress point of blade 7 under a curved frequency, operator reads the amplitude of blade 7 by microscope 6 simultaneously.
