Abstract
The invention belongs to the technical field of pipe fitting testing tools and particularly relates to a testing device for gas tightness of a workpiece. The invention discloses the testing device for the gas tightness of the workpiece. The testing device for the gas tightness of the workpiece comprises a frame body and is characterized in that the frame body is provided with a workpiece groove, and a test gas inlet is formed in the inner wall of the workpiece groove. The frame body is provided with an air pressure detection sensor capable of detecting the gas pressure inside the workpiece and is fixedly connected with an air cylinder through a connection rod. The air cylinder is connected with a pull rod, and the pull rod can be matched with the workpiece groove under the action of the air cylinder to tightly clamp and seal the workpiece. According to the testing device for the gas tightness of the workpiece, mechanization operation can be achieved to the gas tightness detection of the workpiece, the working efficiency is improved, and simultaneously the detection accuracy of the workpiece is enabled to be improved greatly.
Description
Technical field
The invention belongs to pipe fitting testing appliance technical field, relate in particular to a kind of air tightness of workpiece proving installation.
Background technology
In the process of workpiece, often can be processed with a kind of workpiece that impermeability requires that has in workpiece.And this workpiece with impermeability requirement all can carry out impermeability and detect after processed completing.The impermeability that the present workpiece for this type of carries out detects and generally all completes by manually operating.Be all generally manually to take after workpiece, then the air intake opening of workpiece inflated, then detect inductor by air pressure and carry out mensuration to inside workpiece air pressure.Determine whether specification product by the mensuration situation to inside workpiece air pressure.This type of detection method is relatively backward, and efficient is lower, and artificial influence factor is more, and is accurately fixed not high.
Summary of the invention
The object of the invention is to solve above-described technical matters, a kind of air tightness of workpiece proving installation is provided, its technical scheme is as follows:
A kind of air tightness of workpiece proving installation, comprise support body, it is characterized in that, described support body is provided with the workpiece groove, offer test gas air intake opening on the inwall of described workpiece groove, described support body is provided with the air pressure detecting sensor that can detect the inside workpiece gaseous tension, and described support body is fixed with cylinder by connecting rod, described cylinder is connected with push rod, and described push rod can match with the workpiece groove under the effect of cylinder Workpiece clamping is sealed.
Optimal way is to be provided with the station monitor station between described support body and cylinder.
Air tightness of workpiece proving installation provided by the invention in use, only need to be placed on workpiece in the workpiece groove of support body, makes the test gas air intake opening on the workpiece groove communicate with the air intake opening of workpiece.Then start and use cylinder, make cylinder coordinate continuous clamping work pieces with the workpiece groove, make the Workpiece clamping sealing.At this moment, beginning is filled test gas toward test gas air intake opening, makes test gas enter into workpiece, then stops inflation.Because workpiece seals, thus after entering into workpiece, test gas can form certain air pressure, thus detected by the air pressure detecting sensor.By the time through after the regular hour, can observe the situation of air pressure detecting sensor after stopping inflating.If the air pressure that the air pressure detecting sensor detects is more stable, do not change, that impermeability that workpiece just is described is better.If the air pressure change that the air pressure detecting sensor detects is larger, that impermeability that workpiece just is described is relatively poor.
Support body of the present invention is fixed with cylinder by connecting rod, makes whole support body become as a whole with cylinder by connecting rod, makes the sealing property of whole device more good, more stable.
Be provided with the station monitor station between support body of the present invention and cylinder.Can better seal the location to workpiece, reach best sealing effectiveness.In the use procedure of reality, for the identical workpiece of similar model, owing to having large batch of detection like product, thus for faster, better carry out sealing location to workpiece.Can adopt the station monitor station to make the workpiece of this class locate fast, save time, raise the efficiency.
The present invention can detect the impermeability of workpiece and realize mechanized operation having improved work efficiency, makes simultaneously the detection accuracy of workpiece be greatly enhanced.

Embodiment
Illustrate embodiment below in conjunction with Fig. 1:
A kind of air tightness of workpiece proving installation, comprise support body 1, it is characterized in that, described support body 1 is provided with workpiece groove 2, offer test gas air intake opening 3 on the inwall of described workpiece groove 2, described support body 1 is provided with the air pressure detecting sensor 4 that can detect the inside workpiece gaseous tension, and described support body 1 is fixed with cylinder 6 by connecting rod 5, described cylinder 6 is connected with push rod 7, and described push rod 7 can match with workpiece groove 2 under the effect of cylinder 6 Workpiece clamping is sealed.
Optimal way is to be provided with station monitor station 8 between described support body 1 and cylinder 6.
Air tightness of workpiece proving installation provided by the invention in use, only need to be placed on workpiece in the workpiece groove of support body, makes the test gas air intake opening on the workpiece groove communicate with the air intake opening of workpiece.Then start and use cylinder, make cylinder coordinate continuous clamping work pieces with the workpiece groove, make the Workpiece clamping sealing.At this moment, beginning is filled test gas toward test gas air intake opening, makes test gas enter into workpiece, then stops inflation.Because workpiece seals, thus after entering into workpiece, test gas can form certain air pressure, thus detected by the air pressure detecting sensor.By the time through after the regular hour, can observe the situation of air pressure detecting sensor after stopping inflating.If the air pressure that the air pressure detecting sensor detects is more stable, do not change, that impermeability that workpiece just is described is better.If the air pressure change that the air pressure detecting sensor detects is larger, that impermeability that workpiece just is described is relatively poor.
