Referring to Fig. 1, the swirler test fixture of the utility model, 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 to have at least one convex 11; Preferably, the primary importance and the second place are two relative positions of central axis of relative anchor clamps flange 1.Convex 11 is provided with a pull rod shaft 21.Pull bar 2 is connected with convex 11 through 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 qualification 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 through 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 is slidingly matched with this guide-track groove, and regulating block 4 can be moved freely along pull bar 2 directions in guide-track groove through the guide rail raised line.Regulating block 4 is provided with the fixing bolt, and regulating block 4 is through 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 the regulating block 4 and the relative position of pull bar 2.
As additional embodiments; Need not offering guide-track groove on the pull bar 2 and the guide rail raised line is set on regulating block 4; As long as on pull bar 2, offer and the suitable a plurality of bolts hole in regulating block 4 positions commonly used; 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, through 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 through first spring shaft 31, and second end of spring 3 is connected with pull bar 2 through second spring shaft 32.Be pivoted under the connection status perpendicular to anchor clamps flange 1 at pull bar 2, second spring shaft, 32 relative first spring shafts 31 on the pull bar 2 and the line of pull rod shaft 21 are 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 on the position of vertical folder general laws blue 1, be in steady state (SS), can bounce or jump.
As additional embodiments, need not on 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 through 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,, also make stress balance on the horizontal direction of pull bar 2 to add the pulling force of big spring.
Between anchor clamps flange 1 and tube of pressure-stabilizing flange 51, be provided with rubber sheet gasket 6.
Before doing experiment; The position that needs adjustment regulating block 4: pull bar 2 is pulled to the position vertical with anchor clamps flange 1; Along the position of pull bar 2 directions adjustment regulating block 4, guarantee to be connected closely between tube of pressure-stabilizing 5 and the anchor clamps flange 1, nothing leaks gas, with bolt or screw retention regulating block 4.
Before the assembling test anchor clamps, pull bar 2 is in along the radial direction of anchor clamps flange 1,, swirler is assembled in the cavity 13 of anchor clamps flange 1 first end easily even pull bar 2 is in the state parallel with anchor clamps flange 1.
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 (, be about to pull bar 2 and pull the position vertical), compress tube of pressure-stabilizing flange 51, make its abut against clip flange 1 with regulating block 4 with anchor clamps flange 1 like Fig. 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 accomplishing test, as long as pull bar 2 is pulled to the preceding position of assembling laterally.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
