Embodiment Construction

[0024] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.

[0025] Such as Figure 1 to Figure 7 As shown, a leak test fixture for an exhaust manifold includes a clamp body 1, a pad 2 is installed in the upper middle of the clamp body 1, and four seals are installed on the pad 2 along the horizontal direction. Ring 3, cylindrical pins 4 are installed on the upper left end and right end of the pad 2, and a pipe joint 5 connected to the surface of the clamp body 1 is installed on the rear end of the pad 2.

[0026] Two No. 1 clamping and fixing devices 6 are installed on the upper rear of the clamp body 1, and a No. 1 clamping and fixing device 6 and a No. 2 clamping and fixing device 7 are installed on the upper front of the clamp body 1. The No. 1 clamping and fixing device 6 and the No. 2 clamping and fixing device 7 all include a pad 8 fixedl...

Abstract

The invention relates to a leakage test clamp for an exhausting manifold. The leakage test clamp comprises a clamp body, the middle portion of the clamp body is provided with a cushion block, four sealing rings are mounted on the cushion block, cylindrical pins are mounted in the upper left and right ends of the cushion block respectively, and the rear end of the cushion block is provided with a pipe joint; the upper rear part of the clamp body is provided with two No.1 clamping and fixing devices, and the upper front part of the clamp body is provided with a No.1 clamping and fixing device and a No.2 clamping and fixing device; and a shoe plate is arranged beside the rear side of the cushion block, the shoe plate is provided with jack screws in a threaded manner, a support is arranged beside the front side of the cushion block, the support is provided with a screw in a threaded manner, and the rear end of the screw is provided with a plug. On the basis that the exhausting manifold is positioned in two points, the exhausting manifold is fixed and compressed, and the is sealed via the sealing rings and the glug. further, ventilation and leakage test can be realized conveniently. In addition, the leakage test clamp is convenient to use and adjust, and the airtightness detecting effect is better.

Description

technical field [0001] The invention relates to a fixture, in particular to a leak test fixture for an exhaust manifold. Background technique [0002] The exhaust manifold is connected to the cylinder block of the engine, and gathers the exhaust of each cylinder into the exhaust manifold, with divergent pipelines. In order to facilitate the assembly and connection of the exhaust manifold, generally speaking, after the traditional exhaust manifold is processed, in order to ensure the exhaust effect and quality of the exhaust manifold, it is necessary to seal the exhaust manifold. Conduct testing to prevent air leaks. However, due to the complex shape of the exhaust manifold, it is difficult for traditional air tightness testing instruments to detect or assist in the detection of the exhaust manifold. Contents of the invention [0003] In order to solve the defect that the airtightness of the exhaust manifold is difficult to detect, the present invention proposes a leak te...
