Abstract

The invention belongs to a device for measuring workpiece tightness, and in particular relates to a wet leak tester. The wet leak tester mainly comprises an upper plate of a support, a fastening device, air cylinders and a water tank, wherein the fastening device is positioned above the hollow area of the water tank and fixed at the bottom of the upper plate of the support through a fixed shaft; the fastening device comprises a cubic frame which consists of an upper bottom plate and a workpiece supporting plate with through holes by virtue of four fixing columns, and an air cylinder which is fixed at the bottom of the upper bottom plate; and air cylinder connecting seats are fixed on two sides of the upper plate of the support respectively, and are fixedly connected with piston rods of the air cylinders fixed on the two sides of the water tank. The wet leak tester has the beneficial effects that whether the workpiece is qualified or not is tested by adopting a method of pressurizing inside the workpiece and immersing the workpiece in water, the air leaking position can be accurately found according to the bubble position in the water so as to facilitate the subsequent maintenance; and the tightness of the workpiece is determined by directly observing whether bubbles are in the water or not, which is intuitive and efficient.

Description

The wet type leakage tester

Technical field

The invention belongs to the device of measuring workpieces sealing, relate in particular to a kind of wet type leakage tester.

Background technology

At present, foundry enterprise needs it is carried out performing leak test behind the product behind the casting, for example, transmission housing, have the communicator of the wing that dispels the heat etc., method commonly used at present is to suppress in this workpiece, observe manometric reading, judge according to reading whether product is qualified, though this mode can detect substandard product, but for these underproof products, producers also do not know it is that the position where of product produces gas leakage, are unfavorable for later maintenance processing, in addition, the mode that employing is suppressed, could observe pressure gauge reading after last a few minutes such as producers' needs, lose time, be unfavorable for large-scale production.

Summary of the invention

The objective of the invention is to overcome the deficiency of above-mentioned technology, can fast detecting go out workpiece gas leakage position, the wet type leakage tester of precise and high efficiency and provide a kind of.

The present invention for achieving the above object, by the following technical solutions: a kind of wet type leakage tester, mainly comprise support upper plate, fastener, cylinder and water tank, described fastener is positioned at top, water tank hollow out zone and is fixed on support upper plate bottom by stationary shaft, described fastener comprises the cube frame of being made up of by four fixed legs upper plate and the workpiece supporting plate that has air hole, and the cylinder formation, described cylinder is fixed on the upper plate bottom; Described support upper plate both sides are fixed with the cylinder Connection Block respectively, and described cylinder Connection Block is affixed with the piston rod of the cylinder that is fixed on the water tank both sides.

Described cylinder Connection Block is provided with the bar that is slidingly connected, and the described bar that is slidingly connected is slidingly connected with the slip cap that is fixed on the water tank both sides.

Beneficial effect: adopt and suppress in workpiece also whether water-immersed mode test piece is qualified, can find out the gas leakage position accurately according to the bubble position in the water, convenient maintenance later; By whether there being bubble to judge the sealing of workpiece in the Direct observation water, directly perceived efficient.

Description of drawings

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

Embodiment

Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure, a kind of wet type leakage tester, mainly comprise support upper plate 1, fastener 2, cylinder 3 and water tank 4, described fastener is positioned at top, water tank hollow out zone and is fixed on support upper plate bottom by stationary shaft 2-1, and fastener can be changed according to the size shape of workpiece.Described support upper plate both sides are fixed with cylinder Connection Block 5 respectively, the xsect of described cylinder Connection Block is " worker " shape, the support upper plate is fixed on the upper surface of cylinder Connection Block by bolt and nut, the lower surface of described cylinder Connection Block is affixed with the piston rod 3-1 of the cylinder that is fixed on the water tank both sides, piston rod drives the to-and-fro movement of support upper plate, described fastener is mainly by upper plate 2-2, the workpiece supporting plate 2-3 and the cylinder 2-4 that have air hole 2-31 constitute, air hole on the workpiece supporting plate is connected with the tracheae of air lift pump, for guarantee the workpiece supporting plate can and workpiece to be detected between have better sealing, the workpiece splint upper surface posts one deck rubber layer.Described upper plate connects to form the cube frame by four reference columns 7 and workpiece supporting plate, and described cylinder is fixed on the upper plate bottom, and cylinder can be decided according to the size of measured workpiece for a plurality of, and cylinder piston plays the effect of workpiece pressing.In order to guarantee the balance bracket upper plate, it is not produced rock, described cylinder Connection Block is provided with the bar 8 that is slidingly connected, and the described bar that is slidingly connected is slidingly connected with the slip cap 9 that is fixed on the water tank both sides.All be connected with air lift pump by tracheae with upper cylinder, tracheae is provided with the to-and-fro movement that valve comes control cylinder.

During use, contain the water of 2/3rds volumes in the water tank, earlier workpiece is placed on the workpiece supporting plate, the cylinder that unlatching is fixed on the upper plate bottom makes its downward workpiece pressing, workpiece and workpiece supporting plate are combined closely, open air lift pump, to the workpiece internal pressurization, open the cylinder of water tank both sides by the through hole on the base plate, making it drive workpiece moves in water tank, whether whole work-piece is immersed in the water fully, wait the water surface after tranquil 30 seconds, observing has bubble to produce in the water, if have, can judge the position that Work piece sealing is not firm according to the position that bubble produces, it is taken out mark, reseal; Otherwise product is qualified.

The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
