Problems solved by technology

However, due to the influence of testing equipment, personnel and product structure in actual testing, some castings often have defects that cannot be found after special inspection, resulting in problems such as oil leakage or air leakage after the castings are assembled in the processing plant, causing parts to be scrapped. Increased production costs and delays in production progress

Abstract

The invention provides an airtightness detection tool for castings. The airtightness detection tool comprises a support, a base, a trapezoid screw A, a cushion block A, a trapezoid screw B, a cushion block B, a trapezoid screw C, a cushion block C and a breather pipe, wherein the support and the base are of an integrated structure, and the cushion block A is installed at the left end of the support through the trapezoid screw A and can move leftwards and rightwards under screw rotation of the trapezoid screw A; the cushion block B is installed on the top of the support through the trapezoid screw B and can move upwards and downwards under screw rotation of the trapezoid screw B; the cushion block C is installed at the right end of the support through the trapezoid screw C and can move leftwards and rightwards under screw rotation of the trapezoid screw C; the breather pipe is connected to the base and is led into the base, and an outlet is formed in the center of the upper end of the base. The airtightness detection tool can quickly determine defective casting products through detection, reduces machining and assembling costs of a machining factory, shortens adjusting time and improves production efficiency.

Description

Technical field [0001] The present invention is an air tightness detection device, in particular to a casting air tightness detection tool. Background technique [0002] At present, some of the castings produced by our company are delivered to the processing plant and used for parts with air tightness requirements such as pump bodies, hydraulic systems and engines. Before delivery, X-ray inspection and fluorescence inspection methods are mainly used to check the castings for penetrating holes and other defects to prevent the castings from leaking defects. However, in actual testing, due to the influence of testing equipment, personnel and product structure, some castings often have defects that cannot be found after special inspections, causing problems such as oil or gas leakage after the castings are assembled in the processing plant, resulting in scrapped parts. Increased production costs have delayed the production schedule. Summary of the invention [0003] In order to solv...
