Air tightness detection device used for water pump manufacturing

Abstract

The invention provides an air tightness detection device used for water pump manufacturing. The device comprises a machine table, a rear end cover and a compressing bar; a left side of a front end face of the machine table is in hinge joint with a group of connection plate; a middle part of the connection plate is in threaded connection with a group of handle; three groups of the compressing barsare evenly arranged and connected on an external side of a lower end cover through hinge joint; one group of lifting connection rod is jointly connected under the three groups of the compressing barsthrough hinge joint; the lifting connection rod is in sliding connection with the machine table; the lifting connection rod is connected with one group of lifting threaded rod through an internal thread; and the lifting threaded rod is axially connected with the machine table. By controlling the compressing bar through the handle to compress a pump shell, operations are very simple, a good sealingeffect can be realized, the conventional mode of connecting an end cover through a flange to perform sealing is changed, works are simplified, working efficiency is improved, labor force is reduced,and meanwhile, the device provided by the invention is simple in structure and low-cost, and is suitable for being used in daily inspection of workshops.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, detection and measurement, and more specifically relates to an air tightness detection device used in the manufacture of water pumps. Background technique [0002] As the main body of the water pump, the water pump housing needs to have good air tightness requirements. During the production process of the water pump, it is often necessary to test the air tightness of the water pump housing, and remove or repair unqualified products in time, especially For large water pumps, due to their high cost, large volume and inconvenient transportation, on-site testing can effectively reduce cost waste. Now the site generally adopts flanged connection end caps for sealing, and pressurized gas is introduced into the sealing chamber for airtightness. Sex detection. [0003] Based on the above, and in combination with the equipment found in the prior art, the existing way of connecting through t...
