Abstract

The utility model relates to a testing clamp of vibration character of aero-engine pin tenon blades belonging to the technical field of clamping mechanism design, wherein the outer shape of the clamp is in a gantry type structure rotating with an angle of 45 degrees, which is convenient for rotating a blade into the horizontal state for testing. The testing clamp comprises a clamp body, a clamping block, a mandrel and a clamping screw bolt, wherein a locating slot is arranged in the clamp body, the clamping block is fixed in the locating slot, the inner side of the clamping block is in a U-shaped slot structure, the mandrel is traversed into the clamp body and is inserted into the U-shaped slot of the clamping block, and the clamping screw bolt is screwed on the clamp body in the direction which is perpendicular to the axial cord of the mandrel. The clamp device of the utility model is only composed of four parts, and has the advantages of simple design, reasonable installation, not only increases the measuring precision, but also reduces the testing period.

Description

A kind of aeromotor pin tenon blade vibration characteristic test fixture

Technical field

The utility model relates to anchor clamps mechanical designing technique field, particularly a kind of aeromotor pin tenon blade vibration characteristic test fixture.

Background technology

Blade vibration characteristic test fixture in the past is divided into sectional fixture and test fixture two large divisions, the blade clamping is on the test fixture that surplus in the of 20 parts are formed, test fixture is installed on the vibration test system by the sectional fixture of being made up of tens parts again, the anchor clamps test macro that nearly 40 parts are formed is not only very big to the measuring accuracy influence, and the blade installation is loaded down with trivial details, has increased the time of blade testing simultaneously.Grip device of the present utility model only is made up of four parts, and simplicity of design, installation had rationally both increased measuring accuracy, had reduced the test period again.

Summary of the invention

For the shortcoming that the blade vibration characteristic test fixture that remedies in the past exists, the utility model provides a kind of aeromotor pin tenon blade vibration characteristic test fixture, and simplicity of design, installation rationally increase measuring accuracy, reduce the test period.

The profile of these anchor clamps is the planer type structure of 45 ° of rotations, so that blade is rotated into horizontality, convenient test, comprise clamp body, fixture block, plug, hold-down bolt, wherein be provided with locating slot in the clamp body, fixture block is fixed in the locating slot, and the fixture block inboard is the U type groove structure, plug penetrates clamp body and inserts in the U type groove of fixture block, is screwed into hold-down bolt with the perpendicular direction of plug axis on clamp body.

The application process of these anchor clamps is, at first uses bolt that the base of clamp body is directly fixedlyed connected with shaking table, blade tenon inserted in the U type groove of fixture block, passes the blade pin hole with plug again and makes the blade location, holds out against fixture block with hold-down bolt at last.

The principle that the blade location clamps is for to hold out against fixture block by hold-down bolt, and fixture block is outwards extruded blade, and the plug that passes the blade pin hole simultaneously plays the effect of location, vanes fixed, clamping the most at last again.

Grip device of the present utility model only is made up of four parts, and simplicity of design, installation had rationally both increased measuring accuracy, had reduced the test period again.

Description of drawings

Fig. 1 is this clamp structure synoptic diagram;

Fig. 2 is this anchor clamps scheme of installation.

1 clamp body among Fig. 1,2 fixture blocks, 3 plugs, 4 hold-down bolts;

5 shaking tables among Fig. 2,6 blades, 7 bolts.

Embodiment

The profile of these anchor clamps for the rotation 45 ° planer type structure as shown in Figure 1, comprise clamp body 1, fixture block 2, plug 3, hold-down bolt 4, wherein be provided with locating slot in the clamp body 1, fixture block 2 is fixed in the locating slot, fixture block 2 inboards are the U type groove structure, plug 3 penetrates clamp body 1 and inserts in the U type groove of fixture block 2, is screwed into hold-down bolt 4 with the perpendicular direction of plug 3 axis on clamp body 1.

The application process of these anchor clamps as shown in Figure 2, at first use bolt 7 that the base of clamp body 1 is directly fixedlyed connected with shaking table 5, blade 6 tenons are inserted in the fixture block 2, and the pin hole that passes blade 6 with plug 3 is located blade 6 again, holds out against fixture block 2 with hold-down bolt 4 at last.

Claims

1, a kind of aeromotor pin tenon blade vibration characteristic test fixture, it is characterized in that: the profile of these anchor clamps is the planer type structure of 45 ° of rotations, comprise clamp body, fixture block, plug, hold-down bolt, wherein be provided with locating slot in the clamp body, fixture block is fixed in the locating slot, the fixture block inboard is the U type groove structure, and plug penetrates clamp body and inserts in the U type groove of fixture block, is screwed into hold-down bolt with the perpendicular direction of plug axis on clamp body.
