Description

A kind of thermostat casing assembling and airtight detecting apparatus

Technical field

The invention belongs to technical field of tooling clamps, be specifically related to a kind of thermostat casing assembling and airtight detecting apparatus.

Background technology

Thermostat function is that the height according to cooling water temperature is automatically adjusted the water yield entering radiator, changes the circulation of water Scope, to regulate the heat-sinking capability of cooling system, it is ensured that electromotor works within the scope of suitable temperature.Thermostat casing is by joint temperature Device shell block body, hot water inlet pipe, hot water outlet pipe, cold water inlet cooperation assemble, in the process in order to ensure joint temperature The sealing of device enclosure interior, water oil pipe is higher with coordinating of thermostat shell block.And the working environment of thermostat shell block is often Running simultaneously along with the operation of automobile engine, water pipe has vibrations, therefore to thermostat shell block with the connection of other part The quality of fit of water pipe installing hole requires particularly important.

Existing process technology for assemble with the artificial operation break-down of common hydraulic press, and during this frock frequently the most more Change, owing to three water pipe position dimensions of thermostat shell block are asymmetric and not on the same face, need to change not during oil pipe assembling Same frock, the most poor and inefficient when controlling part water pipe position dimension precision, affect the production effect of thermostat casing Secondly rate, airtight detection operation and turning is joined is separate detection, and increasing operation affect productive temp increase cost.

Summary of the invention

The deficiencies in the prior art in view of the above, it is an object of the invention to provide a kind of thermostat casing and assemble and airtight Detection equipment, it is possible to realize the assembling of thermostat casing and airtight detection.

For achieving the above object and other relevant purposes, technical solution of the present invention is as follows:

A kind of thermostat casing assembling and airtight detecting apparatus, including support, support is provided with positioning seat, positioning seat sets It is equipped with sealing gasket, and offers airtight test air inlet, the support above described positioning seat is provided with hold-down mechanism, positioning seat It is provided with on the support of side and seals, with thermostat casing water pipe and thermostat shell block, the sealing top-pressure mechanism that hole is corresponding.

When this equipment uses, first water pipe is installed and compressed be sealed on thermostat shell block by sealing top-pressure mechanism, and To seal hole to seal, then air tightness testing machine supply is entered by airtight test air inlet, tests, and closes and hold one's breath after having tested Density test machine, seals top-pressure mechanism and returns, it is possible to realizes the assembling of water pipe, seal compression, and the airtight survey to thermostat casing Examination.This equipment has once assembled the close detection of circulation of qi promoting of going forward side by side, and reduces operation and changes the time of frock, improves production efficiency, operation Convenient.

Further, described positioning seat includes base plate and the datum plate being arranged on base plate, and described datum plate is provided with Alignment pin, described sealing gasket is arranged on datum plate, and described airtight test air inlet vertically runs through base plate, datum plate and sealing Pad.
