Except purpose described above, feature and advantage, the present invention also has other purpose, feature and advantage.With reference to figure, the present invention is further detailed explanation below.
Description of drawings
The accompanying drawing that constitutes the application's a part is used to provide further understanding of the present invention, and illustrative examples of the present invention and explanation thereof are used for explaining the present invention, do not constitute improper restriction of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation of the swirler test fixture of the preferred embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
Referring to Fig. 1, swirler test fixture of the present invention, the tube of pressure-stabilizing flange 51 that is used for making tube of pressure-stabilizing 5 and anchor clamps flange 1 are near fixing, so that carry out firing chamber swirler test.This swirler test fixture comprises anchor clamps flange 1, pivoting is installed on pull bar 2, spring 3 and the briquetting of anchor clamps flange 1, and briquetting is preferably regulating block 4.
The primary importance at the edge of anchor clamps flange 1 is provided with the cavity 13 of assembling swirler 7, the second place at the edge of anchor clamps flange 1 is protruding at least one convex 11, preferably, primary importance is two relative positions of central axis of relative anchor clamps flange 1 with the second place.Convex 11 is provided with a pull rod shaft 21.Pull bar 2 is connected with convex 11 by this pull rod shaft 21, and pull bar 2 can rotate in vertical plane around pull rod shaft 21.Convex 11 is provided with first end of 12, two ribs of two ribs, 12 half parcel pull bars 2, and is limited with the pull bar revolution space between two ribs 12.The anglec of rotation of two rib 12 restriction pull bars 2 is not more than 90 °.
As additional embodiments, second end of anchor clamps flange 1 can not stretch out convex 11.On second end of anchor clamps flange 1 pull rod shaft 21 is set directly and make, pull bar 2 directly is connected with second end of anchor clamps flange 1 by this pull rod shaft 21.
Can be chosen in according to the model size of swirler testpieces one, two, four, six or eight convexes 11 are set on the anchor clamps flange 1.
Regulating block 4 is installed on the pull bar 2 along the vertical adjustable ground of pull bar.Pull bar 2 offers a guide-track groove (not shown in the accompanying drawing) on one side of anchor clamps flange 1.The side end face that regulating block 4 is connected with pull bar 2 is provided with the guide rail raised line, and this guide rail raised line and this guide-track groove are slidingly matched, and regulating block 4 can be moved freely along pull bar 2 directions in guide-track groove by the guide rail raised line.Regulating block 4 is provided with the fixing bolt, and regulating block 4 is by fixing bolt in pull bar 2.During use, after regulating block 4 was moved to preposition along pull bar 2, the tightening card fixing bolt was fixed regulating block 4 and the relative position of pull bar 2.
As additional embodiments, need not to offer guide-track groove and at regulating block 4 the guide rail raised line is set at pull bar 2, as long as offer a plurality of bolts hole suitable with regulating block 4 positions commonly used at pull bar 2, regulating block 4 optionally be installed on the pull bar 2 along on one of a plurality of installation sites that pull bar is vertically arranged, by bolt regulating block 4 directly is fixed on the pull bar 2 and gets final product.
Convex 11 is provided with first spring shaft 31 away from a jiao of pull rod shaft 21.The medium position of pull bar 2 is provided with second spring shaft 32.First end of spring 3 is connected with convex 11 by first spring shaft 31, and second end of spring 3 is connected with pull bar 2 by second spring shaft 32.Under pull bar 2 was pivoted to connection status perpendicular to anchor clamps flange 1, second spring shaft, 32 relative first spring shafts 31 on the pull bar 2 and the line of pull rod shaft 21 were biased in a side at stabilizing sleeve flange 51 places.At this moment, spring 3 is in extended state, and the pulling force of spring 3 makes pull bar 2 be in steady state (SS) in the position of vertical folder general laws orchid 1, can not beat.
As additional embodiments, need not at convex 11 and pull bar 2 first spring shaft 31 and second spring shaft 32 to be set, can directly spring be connected with pull bar 2 with convex 11 by hinge.First end of spring 3 also can directly be connected with second end of anchor clamps flange 1.A spring 3 can also respectively be set in the both sides of pull bar 2, to add the pulling force of big spring, also make stress balance on the horizontal direction of pull bar 2.
Between anchor clamps flange 1 and tube of pressure-stabilizing flange 51, be provided with rubber sheet gasket 6.
Before doing experiment, need to adjust the position of regulating block 4: pull bar 2 is pulled to the position vertical with anchor clamps flange 1, adjust the position of regulating block 4 along pull bar 2 directions, guarantee to be connected closely between tube of pressure-stabilizing 5 and the anchor clamps flange 1, nothing leaks gas, with bolt or screw secured adjusted piece 4.
Before the assembling test anchor clamps, pull bar 2 is in along the radial direction of anchor clamps flange 1, even pull bar 2 is in the state parallel with anchor clamps flange 1, swirler is assembled in the cavity 13 of anchor clamps flange 1 first end easily.
During test, the swirler testpieces is assemblied on the test fixture.The anchor clamps flange 1 that will install the test fixture of swirler testpieces then aligns with tube of pressure-stabilizing flange 51; At last pull bar 2 is pulled to the inside and put in place (as Fig. 1, be about to pull bar 2 and pull the position vertical with anchor clamps flange 1), compress tube of pressure-stabilizing flange 51 with regulating block 4, make its abut against clip flange 1.At this moment, pull bar 2 after pull rod shaft 21 rotates through spring 3 maximum weighted to the inside, the pulling force of spring 3 can make anchor clamps flange 1 and tube of pressure-stabilizing flange 51 near, and then make this swirler test fixture compress tube of pressure-stabilizing 5, the unlikely gas leakage of tight seal between the two.After finishing test, as long as pull bar 2 is pulled laterally to the preceding position of assembling.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
