Device and method for visually detecting leakproofness of four-station bearing part

Abstract

Provided are a device and method for visually detecting leakproofness of a four-station bearing part. The device is composed of three parts, the first part is a synchronous movement mechanism with a central core shaft (1) driving a cross hanging bracket (3), the second part is a clamping and measuring mechanism of a workpiece to be detected, the third part is a supporting movement mechanism of the central core shaft (1), the first part is arranged at the upper end of the detection device and is connected with the third part arranged on the lower portion of a detection device supporting platform (19) through the central core shaft (1), and the second part is arranged on the upper supporting surface of the detection device supporting platform (19). Through an innovative detection principle and the novel detection structure, four parts can be simultaneously detected, measuring efficiency can be greatly improved, the automatic detection degree is high, and the application range is wide.

Description

technical field [0001] The invention relates to a device and method for detecting the sealing quality of parts, in particular to a device and method for visually detecting the sealing performance of four-station pressure-bearing parts. Background technique [0002] Mechanical pressure-bearing parts need to undergo a pressure test before use to verify whether they can ensure airtightness under the design pressure. Mechanical pressure-bearing products have a wide range of applications, such as machinery manufacturing, petroleum, chemical industry, water supply and drainage, etc. field. In recent years, countless accidents have been caused due to the failure of the airtightness of pressure-bearing parts, which has brought huge losses to relevant departments. Therefore, the airtightness of pressure-bearing parts determines the safety, reliability and durability of machinery and equipment. The airtightness test of pressure-bearing parts is one of the key evaluation indicators fo...

Problems solved by technology

These two methods are simple and convenient to operate and have low requirements on equipment, but they have the following shortcomings: (1) Lack of economical and applicable detection methods and methods, either the accuracy is not enough, or the function is single, and the price is expensive, so it is difficult to adapt to multi-variety sealing Component testing; (2) The detection system is extremely backward. There are basically no test devices for the overall performance test of sealing components in China. Most of the detection systems are physical instruments, which are not intelligent.
