Embodiment Construction

[0018] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0019] see figure 1 , The vortex test fixture of the present invention is used to make the pressure-stabilizing cylinder flange 51 of the pressure-regulating cylinder 5 close to the clamp flange 1 and fix so as to facilitate the combustion chamber vortex test. The vortex test fixture includes a fixture flange 1 , a pull rod 2 pivotally mounted on the fixture flange 1 , a spring 3 and a pressing block, and the pressing block is preferably an adjusting block 4 .

[0020] The first position of the edge of the clamp flange 1 is provided with a cavity 13 for assembling the vortex 7, and the second position of the edge of the clamp flange 1 protrudes outwards with at least one protrusion 11, preferably, the first position and the second The second positi...

Abstract

The invention provides a swirler test fixture, which comprises a fixture flange (1), a pull rod (2) and a press block, wherein a first position of the fixture flange (1) along the edge is used for assembling a swirler (7); the pull rod (2) is pivoted to a second position of the fixture flange (1) along the edge; the second position is opposite to the first position; and the press block is arranged on the pull rod in a sliding way, and is operably pressed against a pressure stabilizing cylinder flange (51) of a pressure stabilizing cylinder (5). When the test fixture is used for testing the swirler, tools such as a spanner, a bolt and the like are not required to be used for fastening the fixture flange and the pressure stabilizing cylinder flange together, the pull rod is required to be rotated only, and an adjusting block is used for clamping the fixture flange and the pressure stabilizing cylinder flange. The operation is safe, time-saving and labor-saving; and the work efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of fixtures, in particular to a vortex test fixture. Background technique [0002] In the combustion chamber vortex test, it is necessary to assemble the test fixture with the vortex fixed on the flange of the pressure regulator for testing to obtain performance data. The assembly of the traditional vortex test fixture is to connect and fasten the vortex test fixture with the flange of the pressure regulator cylinder through bolts. The traditional assembly method is to tighten the bolts every time a vortex test is done, which is troublesome to operate. And every time the vortex machine is tested, it is required that the tension of all bolts be tightened evenly, otherwise it needs to be re-tightened. However, due to the different strengths of each tightening, it is impossible to achieve uniform tension of each bolt fastening. Contents of the invention [0003] The purpose of the present invention is to provide a v...
