Abstract

The invention discloses a leakage testing machine for a radiator core body and belongs to a sealing inspection device. The invention adopts the following technical scheme: lifting air cylinders are arranged at the four corners at the bottom of a water trough respectively, the piston rods of the lifting air cylinders vertically and upwards extend to the interior of the water trough via through holes at the bottom of the water trough, and the top ends of the piston rods of the lifting air cylinders are respectively connected with the four corners of a support plate; water seal rings are arranged between the piston rods of the lifting air cylinders and the through holes at the bottom of the water trough; and two columns of clamping air cylinders are fixedly arranged on the support plate, each column of clamping air cylinders include two air cylinders, and a fixture supported on an air chamber of a radiator is fixedly arranged at the front ends of the piston rods of the clamping air cylinders. The leakage testing machine overcomes the defects in the traditional method that after a water chamber and the radiator core body are assembled, side leakage is detected, the water chamber and the radiator core body need to be disassembled and welded again, so that the production efficiency is improved, and the production cost is reduced.

Description

The radiator core body leakage tester

Technical field

The present invention relates to a kind of inspection of hermetic seal device, particularly a kind of radiator core body leakage tester.

Background technology

Heating radiator belongs to automobile cooling system, and the heating radiator in the engine water-cooling system for water is made up of four parts such as intake chamber, water-supplying chamber, main leaf and radiator core bodies.The automobile radiators inspection of hermetic seal is the critical process during automobile radiators is produced; Owing to will weld between radiating tube and the main leaf; If leak the weldering phenomenon, then can make the chilled water in the hydroecium get into heat-radiation belt from the slit between radiating tube and the main leaf, can cause corrosion to heat-radiation belt.In the past, after heating radiator had welded, by artificial visually examine's inspection, because leakage welding zone territory is very little, manual work sometimes was difficult to find, after installing hydroecium, when trying the water, found to have leakage welding zone territory, then will remove hydroecium and carry out repair welding, wasted time and energy and ten minutes inconvenience.

Summary of the invention

In order to overcome the shortcoming that above-mentioned prior art exists, the object of the present invention is to provide a kind of radiator core body leakage tester.This device is exclusively used in automobile water-cooling heating radiator inspection of hermetic seal, can accomplish the back in heating radiator welding and try the water to heating radiator, has avoided installing and has found that leakage welding zone territory dismantles the drawback that hydroecium carries out repair welding again behind the hydroecium at once.

In order to address the above problem; The present invention adopts following technical scheme: a kind of radiator core body leakage tester; It is characterized in that; On four angles, bottom of a tank, be respectively arranged with a lift cylinder, the piston rod of described lift cylinder stretches into tank inside vertically upward through the through hole of bottom of gullet, and the top of the piston rod of said lift cylinder is connected on four angles of a back up pad; Be provided with waterstop ring between the piston rod of described lift cylinder and the through hole of bottom of gullet; On described back up pad, be fixed with two row and clamp cylinder, every row clamp cylinder and are provided with two at least, and the piston rod front end of said clamping cylinder is fixed with the anchor clamps of overhead on the heating radiator air chamber.

The said back up pad structure that takes the shape of the letter U is made up of a transverse slat and the riser that is arranged on the transverse slat both sides, and both sides riser horizontal direction equal intervals respectively is fixed with five clamping cylinders.

Said back up pad is provided with leaking hole.

The invention has the beneficial effects as follows: avoided heating radiator welding to accomplish, it is incomplete that hand inspection leaks the welding zone territory, finds to leak the welding zone territory and after hydroecium is installed, try the water, the do over again drawback of repair welding of the hydroecium of must dismantling.Can before hydroecium is installed, inspection leak the welding zone territory, repair welding has in time improved work efficiency, has reduced production cost.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is done further explanation:

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the perspective view of the embodiment of the invention;

Among the figure: 1 clamps cylinder, 2 anchor clamps, 3 back up pads, 31 leaking holes, 32 risers, 4 tanks, 5 lift cylinders.

Embodiment

Like Fig. 1, shown in 2, this radiator core body leakage tester comprises lift cylinder 5, tank 4, back up pad 3, clamps parts such as cylinder 1 and anchor clamps 2.

On four angles, bottom of tank 4, be respectively arranged with a lift cylinder 5; The piston rod of described lift cylinder 5 stretches into tank inside vertically upward through the through hole of bottom of gullet, and the top of the piston rod of said lift cylinder is connected on four angles of a back up pad 3; Be provided with waterstop ring between the piston rod of described lift cylinder and the through hole of bottom of gullet.

On described back up pad 3, be fixed with two row and clamp cylinder 1, every row clamp cylinder 1 and are provided with two at least, are positioned at each side of heating radiator hydroecium, and the heating radiator hydroecium is combined closely with core body.The piston rod front end of said clamping cylinder 1 is fixed with the anchor clamps 2 of overhead on the heating radiator hydroecium, the clamping that utilizes these anchor clamps 2 to realize heating radiator hydroecium and core body.Back up pad 3 structure that takes the shape of the letter U is made up of the transverse slat and the riser 32 that is arranged on the transverse slat both sides of a level, and riser 32 horizontal direction equal intervals in both sides respectively are fixed with five clamping cylinders 1, and leaking hole 31 is arranged on the transverse slat of level.

During use, the piston rod of lift cylinder 5 is stretched out 3 rises of the back up pad in the tank, break away from the water surface; Radiator water kept flat to the back up pad 3 clamp between the cylinders 1, clamp cylinder 1 ventilation and hydroecium and radiator core body are clamped the piston rod of lift cylinder 5 recovery then at two row; Heating radiator immerses in the water, and sealing test is carried out in ventilation in hydroecium, as finding to leak the welding zone territory; The lift cylinder piston rod stretches out, and unclamps anchor clamps 2, and hydroecium breaks away from radiator core body naturally; Carry out repair welding then, so just avoided traditional approach after hydroecium and radiator core body assembling completion, find to leak weldering; Need take hydroecium and radiator core body apart drawback that weldering again produces again, improve production efficiency, reduce production cost.
