Description

one

The invention relates to vehicle construction, namely, devices for testing products for leak tightness on in-line mechanized ones. lines by a pneumohydraulic method.

A device for testing leaktightness is known, containing a bath for placing the tested products, informs1; (with a container of liquid with it, a line for supplying compressed air to the container 1.

The disadvantage of the device is that it provides a leakproofness test with low sensitivity.

Closest to the present invention is a device for testing products for tightness, comprising a conveyor with guides for placing test products, a chamber for pressure testing products with compressed gas and a pneumatic system for supplying compressed gas to chamber 2.

The purpose of the invention is to increase productivity.

To achieve this goal, the device is equipped with a liquid container, two flexible pipes connecting the container and the chamber to each other, respectively one from the bottom, the other from above, cassettes for products mounted on the guides, and a drive having a cam camshaft and interacting with it two vertically movable rods and a lever mechanism for moving

10 cassettes, the camera is detachable.

its bottom is fixed on one of the rods, and a container for liquid is installed on the other.

FIG. 1 shows the device, general view; in fig. 2 - also, side view; in fig. 3, 4, and 5 ras: 5) the total position of the elements of the device.

A device for testing products for tightness contains chamber 1

20 for placing in the cassette 2 test articles 3 connected by flexible pipes 4 and 5 with a capacity of 6 for a liquid. Chamber 1 is equipped with compressed gas supply pneumatic system,

25 comprising a pipeline 7 with a gas supply valve 8 and a pipeline 9 with a gas drain valve 10. The bottom is 11 cameras. 1 is provided with guides 12 for accommodating the cassettes 2 and fixed to

30 vertically movable rod 13,

interacting with the cam 14 distribution; shaft 15 drive

16. A shaft is mounted on shaft 15.

17, interacting with the rod 18, on which the container b and the cam 19, interacting with the lever-rocker mechanism 20 for moving the cassettes 2 with the articles from the conveyor 21 to the bottom 11 of the camera, are fixed.

and sequential: the bottom of the camera on the conveyor 22.

The device works as follows.

The cassette 2 with the products 3 is moved by means of a lever-rocker mechanism 20, interacting with the cam 19 of the camshaft 15 of the drive 16, from the conveyor 21 to the guides 12 located at the bottom 11 of the chamber 1 (Fig. 2). In this case, the bottom 11 and the container 6 are in the lower position (Fig. 2 and 3). After loading the products 3, the bottom 11, mounted on the rod 13, rises under the influence of the cam 14 and closes the chamber 1, the valve 9 opens and the compressed gas through the pipeline 7 enters the chamber 1 (Fig. 4), from where the flexible pipeline 4 enters the container 6 Then, from the cam 17 through the rod 18, the liquid container b rises, at this, the liquid from it through the flexible pipe 5 flows into the chamber 1 and floods the product 3, then the valve 8 closes and the valve 10 opens and the compressed gas through the pipeline 9 vents into the atmosphere. Unsealed products exposed (bubbles of air escaping from them under water (Fig. 5).

The device automates the loading and unloading of products into the test chamber with group monitoring of the leaktightness of the products, which increases the performance of the test equipment.
