Description

Technical Field

[0001] The invention relates to a safety inspection device for an automobile radiator, in particular to a sealing inspection tool for a radiator. Background Art

[0002] Before leaving the factory, the automobile radiator must be 100% sealed and tested. Only when it does not leak under the required pressure can it meet the factory standards. The sealing test requires the radiator's water inlet and outlet to be sealed, and 0.15-0.20MPa of gas must be filled into the radiator.

[0003] At present, the sealing inspection of automobile radiators before leaving the factory generally adopts the internal expansion method, that is, the inner wall of the water chamber mouth is sealed to achieve the sealing effect. The disadvantage of this method is poor safety. Since the inside of the water chamber mouth is a smooth cylinder, the tooling often falls off and even injures people. Summary of the invention

[0004] In view of the problem of poor safety in the current sealing inspection of automobile radiators using an internal expansion method before leaving the factory, the purpose of the present invention is to provide a radiator sealing inspection tool.

[0005] The objective of the present invention is achieved through the following technical solutions:

[0006] The present invention comprises a quick clamp, a clamp seat, a clamping sleeve, a rubber fixing sleeve, a rubber sleeve and a threaded plate, wherein the upper end of the rubber fixing sleeve is fixedly connected with the threaded plate, the inner surface of the lower end of the rubber fixing sleeve is installed with a rubber sleeve, and the lower end of the rubber fixing sleeve is jacketed on the water chamber opening of the water chamber of the water radiator; the clamp seat is threadedly connected to the threaded plate, the quick clamp is hinged with the clamp seat, the clamping column on the quick clamp passes through the clamp seat and can move relatively with the clamp seat, a clamping sleeve covering the water chamber opening is provided below the clamping column, the clamping sleeve abuts against the rubber sleeve, and an air inlet connected with the water chamber opening is opened on the clamping sleeve; the clamping sleeve is pressed down by the clamping column on the quick clamp, the clamping sleeve squeezes the rubber sleeve, and the rubber sleeve is squeezed and deformed to hold the water chamber opening to achieve sealing.

[0007] Wherein: a water chamber opening protrusion is arranged on the outer surface of the water chamber opening to prevent the entire sealing inspection tooling from escaping from the water chamber opening.

[0008] The water chamber opening protrusions are divided into two, one at the top and the other at the bottom. The water chamber opening protrusion located at the top abuts against the compression sleeve, and the water chamber opening protrusion located at the bottom abuts against the rubber sleeve and the rubber fixing sleeve.

[0009] The compression sleeve is in the shape of a flat plate, and the edge of the flat plate extends downward, the lower surface of the flat plate abuts against the top of the water chamber opening, and the extension portion A extending downward covers the periphery of the water chamber opening.

[0010] A stopper B for connecting and positioning with a rubber sleeve is provided on the outer side of the lower end portion of the extension portion A.

[0011] The lower end of the rubber fixing sleeve extends radially inward and then upward, and a groove is provided on one side of the upwardly extending extension portion B close to the rubber fixing sleeve, and the lower end of the rubber sleeve is inserted into the groove.

[0012] The upper and lower ends of the rubber sleeve are both provided with stoppers A.

[0013] The upper end of the clamp seat is used to be hinged with the quick clamp, and the lower end of the clamp seat is a threaded section that is threadedly connected to the threaded plate. The degree of tightness of the sealing inspection tooling to the water chamber mouth is adjusted by the depth of the threaded section screwed into the threaded plate.

[0014] The advantages and positive effects of the present invention are:

[0015] 1. The present invention adopts an external embracing structure design, and utilizes the deformation of the compression sleeve to embracing the water chamber opening, which is safe and reliable.

[0016] 2. A water chamber opening protrusion is provided on the outer surface of the water chamber opening of the present invention to further prevent the sealing inspection tooling from falling off from the water chamber opening. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] like Figures 1 to 3As shown, the present invention includes a quick clamp 1, a clamp seat 10, a clamp sleeve 4, a rubber fixing sleeve 5, a rubber sleeve 6 and a threaded plate 8, wherein the upper end of the rubber fixing sleeve 5 is fixedly connected to the threaded plate 8, the inner surface of the lower end of the rubber fixing sleeve 5 is installed with the rubber sleeve 6, and the lower end of the rubber fixing sleeve 5 is jacketed on the water chamber port 7 of the water chamber 12 of the water radiator; the clamp seat 10 is threadedly connected to the threaded plate 8, the quick clamp 1 is hinged to the clamp seat 10, the clamping column 11 on the quick clamp 1 passes through the clamp seat 10 and can move relative to the clamp seat 10, the clamping column 4 covering the water chamber port 7 is provided below the clamping column 11, the clamping sleeve 4 is abutted against the rubber sleeve 6, and the clamping sleeve 4 is provided with an air inlet 3 connected to the water chamber port 7.

[0023] The upper end of the clamp seat 10 of this embodiment is used to be hinged with the quick clamp 1, and the lower end of the clamp seat 10 is a threaded section 2 threadedly connected to the threaded plate 8. The degree of tightness of the sealing inspection tooling to the water chamber mouth 7 is adjusted by the depth of the threaded section 2 screwed into the threaded plate 8.

[0024] The compression sleeve 4 of this embodiment is in the shape of a circular flat plate, and the edge of the flat plate extends downward. The material is iron, the lower surface of the flat plate abuts against the top of the water chamber opening 7, and the extension portion A extending downward is in the shape of a circular ring, covering the outer periphery of the water chamber opening 7. A stopper B15 is provided on the outer side of the lower end of the extension portion A.
