Description
Technical field
The utility model relates to a kind of tubular workpieces endoporus instant sealing device, belongs to endoporus field of sealing technology.
Background technique
The two ends outer round surface of tubular workpieces needs to be immersed in steam phosphating liquid and carries out a surface heat phosphorating treatment, and two ends endoporus will seal, and Phosphating Solution can not be entered in endoporus.Traditional encapsulating method firmly fills in two stomidiums with cone-shape rubber, and the shortcoming of the method is: when filling in hole, due to firmly in different size, make sealing effect unreliable, comes off even at work; The cone rubber stopper of often kind of Dimensions can only be used for the inner hole of workpiece of dimension.
Model utility content
The purpose of this utility model is that traditional endoporus encapsulating method efficiency is low, poor reliability, rubber stopper specification quantity are many in order to solve, and provides a kind of endoporus instant sealing device.
The purpose of this utility model is achieved through the following technical solutions:
A kind of tubular workpieces endoporus instant sealing device of the present utility model, comprises two taper platens, radial deformation body, screw rod and adjusting nut;
Two press plate structures are identical, have the circular discs structure of through hole all, and platen one side is plane, and another side is the conical surface of intermediate projections;
Radial deformation ring is that elastic rubber material is made, and two end faces of radial deformation ring are processed with the conical surface expanded from endoporus to outer rim respectively, and the conical degree of conical surface of radial deformation ring two end faces and the conical degree of conical surface of platen match;
Front platen is socketed in the front end of screw rod and is welded and fixed with screw rod, and the conical surface of front platen backwards; The screw rod of front platen rear end is socketed successively radial deformation ring and rear platen, the conical surface of rear platen forward; Adjusting nut is threaded in the rear end of platen after on screw rod.
For improving the utility model further, the wear ring that the outer wall cementation of radial deformation ring has one deck to be processed by wear-resisting deformable material, to strengthen the working life of seal arrangement.
For improving the utility model further, the rear end of screw rod has the circumferential positioning hole of radial aperture, in this hole, insert rocking handle, can more be conducive to screwing up between screw rod and adjusting nut.
Working procedure
The side endoporus of tubular workpieces to be sealed put into by the utility model seal arrangement radial deformation ring being in free state, pass through rotating adjusting nut, make its front end to screw rod that axial displacement occur, and then make two of adjusting nut front end platens by respective conical surface clamping radial deformation ring, radial deformation is there is in radial deformation ring under the clamping force effect of two platens, make the radial deformation ring outer wall after distortion be close to the inwall of tubular workpieces to be sealed, realize the sealing of bore ends in tubular workpieces.
Beneficial effect
A kind of endoporus instant sealing device structure of the present utility model is simple, be easy to operation, good sealing effect, be specially adapted to the occasion that inner hole of workpiece port needs frequently to seal in short-term, installing/dismounting is fast easy, can greatly increase work efficiency, and has important use value.
