Air tightness detection frame for filter housing

Abstract

The invention discloses an air tightness detection frame for a filter housing. The middle of a positioning bottom plate is vertically connected with a vertical mounting plate in a welded manner, an inlet end to be detected of the housing is mounted in a recess hole formed in the left side surface of the vertical mounting plate, the left tail end of the housing is abutted and clamped by an abuttingclamp plate, the right surface of the abutting clamp plate is fixedly connected with a connecting nut, the connecting nut is connected with one end of a guide screw rod in a threaded manner, the guide screw rod is mounted on the vertical mounting plate in an inserted manner, the other end of the guide screw rod is connected with a clamping groove of a pushing handle rod in a fastened and insertedmanner, a tension spring is mounted on the guide screw rod in a sleeving manner, and two ends of the tension spring are fixedly connected with the connecting nut and the left surface of the verticalmounting plate. By the aid of the technical scheme, the air tightness detection frame is simple in structure and convenient to assemble and mount, and the housing is conveniently and firmly clamped and mounted between the abutting clamp plate and the vertical mounting plate, so that air tightness detection is facilitated.

Description

Technical field [0001] The invention relates to an airtightness detection frame of a filter housing, which is applied to the technical field of filter production. Background technique [0002] In the process of filter production, the airtightness of the filter housing needs to be tested. A filter with good airtightness can effectively prevent oil leakage. However, the airtightness test During the process, due to the cylindrical shape of the filter housing, it is inconvenient to locate and install the filter housing on the detection frame, and it is easy to cause the positioning and installation to be unstable, causing air leakage at the inlet end of the filter housing. Circumstances cause data deviation to the test results. To this end, we designed a test frame for air tightness of the filter housing. Summary of the invention [0003] In order to solve the shortcomings of the existing technical solutions, the invention discloses an air-tightness test frame of the filter housing....

Problems solved by technology

[0002] During the production process of the filter, it is necessary to conduct an air tightness test on the filter housing. A filter with good air tightness can effectively prevent oil leakage, but when the air tightness test is carried out During the process, due to the cylindrical shape of the filter housing, it is inconvenient to install the filter housing on the detection frame for positioning and installation, and it is easy to cause unreliable positioning and installation, resulting in air leakage at the inlet end of the filter housing. situation, causing data deviation to the test results
