Utility model content
Technical problem to be solved in the utility model is in that to provide the airtight inspection machine of dry and wet combined type that a kind of accuracy is good, work efficiency is high.
The technical solution of the utility model is as follows: a kind of airtight inspection machine of dry and wet combined type, including water tank, it is characterised in that: the middle part in described water tank arranges water container, and this water container is connected with the lower cavity of water tank by the through hole bottom it; In water container, it is arranged to support the sealing panel of workpiece, the top of sealing panel it is positioned at for the hold down gag of workpiece pressing, the top of this hold down gag is connected with the piston rod of cylinder, and described cylinder is installed on the top of water tank, and the piston rod of cylinder stretches out straight down; Arranging electrical control cubicles on the side of water tank, electrical control cubicles is provided with display lamp; Pressure test device includes source of the gas, trachea, three-way valve and two are in charge of, one of described trachea is connected with source of the gas, the other end of trachea is connected with the import of three-way valve, first outlet of three-way valve is in charge of with first and is connected, first be in charge of can with the inner space of workpiece, second outlet of three-way valve is in charge of with second and is connected, and the second lower cavity being in charge of with water tank connects.
Adopt above technical scheme, first gear box workpiece to be detected is placed on sealing panel, the opening end making workpiece is supported by sealing panel down, then cylinder action is controlled, the piston rod making cylinder extends downwardly from, the piston rod of cylinder drives hold down gag to move downward, until hold down gag is oppressed on workpiece, the opening end making workpiece engages with sealing panel closely, then pass through source of the gas and first and be in charge of the compression air being filled with 0.2MPa in the inner chamber of workpiece, if compressed-air actuated force value is not above regulation changing value within the time of regulation, workpiece is air tight, display lamp is shown as green light, workpiece is qualified,If compressed-air actuated force value exceedes regulation changing value within the time of regulation, workpiece leaks gas, and display lamp is shown as red light, and workpiece is defective. When workpiece is defective, it is in charge of by source of the gas and second in water tank, passes into compression air, the hydraulic pressure in water tank is entered in water container, and flood workpiece, then compression air is filled with in the inner chamber of workpiece, observe the surface of workpiece, see that where emits bubble, workpiece where can be detected in gas leakage.
As preferably, described water tank is square box structure.
Beneficial effect: this utility model simple in construction, assembles easily, and cost is low; By the mode of dry-and-wet combined, it is possible to accurately whether detection gear box leaks gas and where gas leakage, not only easy and simple to handle, and detection efficiency is high, and the product for various types of gear boxes and other belt type cavity is all applicable, and range of application is widely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is pneumatic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1 and Figure 2, water tank 1 is preferably square box structure, and the top of water tank 1 is provided with opening, in order to gear box workpiece 12 is put into or taken out. Cylinder 5 is installed by central authorities at water tank 1 top cover, and the piston rod of cylinder 5 stretches out straight down, and the piston rod of cylinder 5 stretches in water tank 1. Middle part in water tank 1 is fixedly installed water container 2, and the bottom of water container 2 is provided with through hole, and size and the number of through hole are determined according to actual needs, and water container 2 is connected with the lower cavity of water tank 1 by the through hole bottom it. Being arranged to support the sealing panel 3 of workpiece in water container 2, be positioned at the top of sealing panel 3 for the hold down gag 4 of workpiece pressing, the top of this hold down gag 4 is connected with the piston rod of cylinder 5.
As shown in Figure 1 and Figure 2, pressure test device includes source of the gas 7, trachea 8, three-way valve 9 and two are in charge of, one of trachea 8 is connected with source of the gas 7, the other end of trachea 8 is connected with the import of three-way valve 9, first outlet of three-way valve 9 is in charge of 10 with first and is connected, first is in charge of 10 can with the inner space of workpiece, and the second outlet of three-way valve 9 is in charge of 11 with second and is connected, and second is in charge of 11 connects with the lower cavity of water tank 1.
