Description
Technical field
The utility model belongs to pipe fitting testing appliance technical field, relates in particular to a kind of air tightness of workpiece proving installation.
Background technology
In the process of workpiece, in workpiece, be processed with a kind of workpiece that impermeability requires that has through regular meeting.And this workpiece with impermeability requirement all can carry out impermeability and detect after processed finishing.The impermeability that the present workpiece for this type of carries out detects and generally all finishes by manually operating.Generally all be manually to take behind the workpiece, then the air intake opening of workpiece inflated, detect inductor by air pressure then and carry out mensuration to the workpiece air pressure inside.Judge whether to be specification product by the mensuration situation to the workpiece air pressure inside.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 purpose of this utility model is to solve above-described technical matters, and a kind of air tightness of workpiece proving installation is provided, and 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 workpiece internal gas pressure, and described support body is fixed with cylinder by connecting rod, described cylinder is connected with push rod, and described push rod can be under the effect of cylinder and a workpiece groove workpiece clamp tightening seal that matches.
Optimal way is to be provided with the station monitor station between described support body and the cylinder.
The air tightness of workpiece proving installation that the utility model provides in use, only need be placed on workpiece in the workpiece groove of support body, makes that the test gas air intake opening on the workpiece groove communicates with the air intake opening of workpiece.Start to use cylinder then, make cylinder cooperate continuous clamping work pieces with the workpiece groove, make the workpiece clamp tightening seal.At this moment, beginning is filled test gas toward test gas air intake opening, makes test gas enter into workpiece, stops inflation then.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 to inflate.If the detected air pressure of air pressure detecting sensor is more stable, do not change, that impermeability that workpiece just is described is better.If the detected air pressure change of air pressure detecting sensor is bigger, that impermeability that workpiece just is described is relatively poor.
Support body described in the utility model is fixed with cylinder by connecting rod, makes whole frame body become as a whole with cylinder by connecting rod, makes that the sealing property of whole device is more good, more stable.
Be provided with the station monitor station between support body described in the utility model and the cylinder.Can better seal the location to workpiece, reach best sealing effectiveness.In the use of reality, for the identical workpiece of similar model owing to have a 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 utility model can detect the impermeability of workpiece and realize mechanized operation, has improved work efficiency, makes the detection accuracy of workpiece be greatly enhanced simultaneously.

Embodiment
Specify 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 workpiece internal gas pressure, 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 be under the effect of cylinder 6 and workpiece groove 2 a workpiece clamp tightening seal that matches.
Optimal way is to be provided with station monitor station 8 between described support body 1 and the cylinder 6.
The air tightness of workpiece proving installation that the utility model provides in use, only need be placed on workpiece in the workpiece groove of support body, makes that the test gas air intake opening on the workpiece groove communicates with the air intake opening of workpiece.Start to use cylinder then, make cylinder cooperate continuous clamping work pieces with the workpiece groove, make the workpiece clamp tightening seal.At this moment, beginning is filled test gas toward test gas air intake opening, makes test gas enter into workpiece, stops inflation then.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 to inflate.If the detected air pressure of air pressure detecting sensor is more stable, do not change, that impermeability that workpiece just is described is better.If the detected air pressure change of air pressure detecting sensor is bigger, that impermeability that workpiece just is described is relatively poor.
Claims (2)
