Abstract
The utility model relates to a fitting for a leak tester, particularly a rigid caging device for plugging. A plugging seat is connected with an oil cylinder piston rod, and the front end surface of the plugging seat is fixed with an elastic plug. The structure of the utility model is simple, when the utility model is used for testing leak for a workpiece, the workpiece is caged and plugged, the plugging protruding amount can determine the deformation amount, the consistency of the plugging deformation amount every time can be ensured, thereby, the utility model can solve the problems that the leak testing repeating detection can be affected by the plugging deformation amount and the accuracy is low.
Description
Technical field:
The utility model relates to machine tool accessory, especially for the leakage tester accessory of workpiece leak test.
Background technology:
Be to adopt the direct shutoff of shutoff seat during leak test shutoff workpiece at present, shutoff seat leading section does not all have stop means, shutoff deflection difference during each shutoff, thus directly influence detected value, cause the low problem of duplicate detection precision.
Summary of the invention:
The purpose of this utility model is to address the above problem, and a kind of Plugging Rigid Caging Device is provided, and is simple in structure, guarantees shutoff deflection unanimity, improves accuracy of detection.
The technical scheme that the utility model is adopted for achieving the above object is: Plugging Rigid Caging Device, and the shutoff seat links to each other with the oil cylinder piston bar, and shutoff seat front end face is fixed with the elasticity shutoff.
On the described shutoff seat fixedly buting iron is housed, has screw thread to cooperate on the shutoff seat with adjustable nut.
Described elasticity shutoff is rubber or polyurethane shutoff.
The utility model is simple in structure, and is practical, when being used for the workpiece leak test, Plugging Rigid Caging Device is with the spacing shutoff of workpiece, the protrusion amount of shutoff is determined deflection, guarantees the consistance of each shutoff deflection, thereby has solved the leak test duplicate detection because of the low problem of shutoff deflection influence precision.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is another structural representation of the utility model.
Embodiment:
Plugging Rigid Caging Device as shown in Figure 1, oil cylinder (cylinder) 4 fixing with support 5 on, shutoff seat 2 links with oil cylinder (cylinder) 4 piston rods, shutoff seat 2 front end faces are embedded with rubber shutoff 1, shutoff 1 can be sealed workpiece in the protrusion amount (shutoff deflection) of shutoff seat 2 front end faces, can guarantee that again shutoff seat 2 fronts contact with workpiece, guarantee each shutoff deflection unanimity, improve leak test duplicate detection precision.
Plugging Rigid Caging Device as shown in Figure 2, fixedly buting iron 6 and adjustable nut 3 also are housed on the shutoff seat 2, on adjustable nut and the shutoff seat threaded engagement is arranged, adjust adjustable nut 3 and fixing buting iron 6 relative positions, determine shutoff 1 deflection, fastening adjustable nut 3, thus each shutoff deflection unanimity guaranteed, improve leak test duplicate detection precision.
Claims (3)
