Splenium, the press section are used to extrude first, second oil sealing, and the diameter of the press section is less than described first, second oil
The external diameter of the envelope and press section is provided with the projection being engaged with the breach.
In addition, present invention additionally comprises following attached technical scheme：
The guide sleeve center offers pilot hole, and the lead coordinates with the pilot hole.
The guide sleeve is additionally provided with the positioning port being engaged with the end difference, the positioning port and the end difference
During cooperation, the press section is aligned with the mounting hole.
The extrusion also includes the supporting part being connected with the press section, and first, second oil sealing can be sheathed on institute
State on supporting part.
The breach includes bottom surface, and when first oil sealing is installed in place, the projection is in contact with the bottom surface.
The convex portion includes top surface, and when second oil sealing is installed in place, the projection is in contact with the top surface.
Compared to prior art, the advantage of the invention is that：
1. projection in Workpiece notch can be embedded in by setting so that the first oil sealing and the equal energy of the second oil sealing can be ensured
It is installed in place, and overvoltage will not occurs.
2. pass through the positioning port for setting and coordinating with the end difference of workpiece so that when oil sealing pushes can accurately and mounting hole
Alignment, precision are high.
3. by setting the lead and pilot hole that cooperate so that straight line pushes oil sealing all the time, is not susceptible to incline
Tiltedly, stuck phenomenon.
4. by setting press section and supporting part so that when oil sealing pushes will not run-off the straight, reliability is high.

Embodiment
Technical solution of the present invention is made below in conjunction with preferred embodiment and its accompanying drawing further it is nonrestrictive specifically
It is bright.
As shown in Figures 1 to 4, corresponding to a kind of double oil seal pressing mechanism of preferred embodiment of the present invention, for successively will
First oil sealing 1a and the second oil sealing 1b press-in workpiece 2 mounting hole 2a in, be provided with the end face 2e of workpiece 2 convex portion 2b and
The end difference 2d being looped around around the 2b of the convex portion, mounting hole 2a are opened in convex portion 2b center, are further opened with the 2b of convex portion
The breach 2c communicated with mounting hole 2a.
Double oil seal pressing mechanism includes guide sleeve 3 and the extrusion 4 with the removable connection of guide sleeve 3.
The center of guide sleeve 3 offers pilot hole 3a and the positioning port 5 coordinated with end difference 2d, when positioning port 5 and ladder
After portion 2d is connected, pilot hole 3a is aligned with mounting hole 2a.
Extrusion 4 includes lead 6, supporting part 6a, press section 6b and the striking head 10 for being connected to the one end of lead 6.Strike
Tap the head 10 and lead 6 be bolted, it is used to directly bear hammer, the percussion of hammer or the extruding of pressing machine.Squeeze
Splenium 6b and supporting part 6a is connected to the other end of lead 6, and press section 6b is used to directly extrude oil sealing, supporting part 6a diameter
It is slightly less than the diameter of oil sealing so that first, second oil sealing 1a, 1b can be set on supporting part 6a.Press section 6b and support
Portion 6a mutual cooperation positioning oil seals so that oil sealing will not install inclined bad phenomenon in extrusion process.
Press section 6b peripheries are provided with the projection 8 coordinated with breach 2c, and projection 8 can be embedded in breach 2c.When the first oil
When envelope 1a is installed in place, projection 8 contacts with breach 2c bottom surface 7, prevents extrusion 4 from continuing to push；When the second oil sealing 1b is installed
When in place, projection 8 is in contact with convex portion 2b top surface 9, prevents extrusion from continuing to push.The structure can ensure that oil sealing is installed
In place and overvoltage will not be occurred.In the present embodiment, lead 6, supporting part 6a and press section 6b are formed in one.
In use, first the first oil sealing 1a is set on supporting part 6a, it is fixed then to coordinate positioning port 5 and end difference 2d
Position, rotary squeezing part 4 make it that projection 8 is located at breach 2c surface, the striking head that hits with a hammer 10 or are extruded with pressing machine
Striking head 10 causes the first oil sealing 1a to be squeezed into mounting hole 2a, after projection 8 contacts with breach 2c bottom surface 7, oil sealing peace
Position is attached to, can not continue to push；Lift this double oil seal pressing mechanism, the second oil sealing 1b is set on supporting part 6a, then will
Positioning port 5 and end difference 2d, which coordinates, to be positioned, and rotary squeezing part 4 causes 8 surfaces for being located at breach 2c of projection, is struck with hammer
Hit striking head 10 or extrude striking head 10 with pressing machine so that the second oil sealing 1b is squeezed into mounting hole 2a, when the second oil
When envelope 1b is installed in place, projection 8 is in contact with convex portion 2b top surface 9, can not continue to push.
Such a mounting means, second oil sealing is installed again after first oil sealing is installed in place, without by second oil sealing
First oil sealing of extruding is installed, and effectively can be installed in place two oil sealings, and will not damage oil sealing by pressure.
Whether it is aligned in order to facilitate observation projection 8 with breach 2c, opening for observation can be opened up in the outer wall of guide sleeve 3
Mouth (not shown), to facilitate operation.
, can also be below workpiece in order to prevent workpiece directly with deck contact defective work piece surface or damage table top
Upper supporting piece 11 is padded, support member 11 optionally can open up avoidance supporting part 6a avoid holes 11a.
Advantages of the present invention is as follows：
1. projection in Workpiece notch can be embedded in by setting so that the first oil sealing and the equal energy of the second oil sealing can be ensured
It is installed in place, and overvoltage will not occurs.
2. pass through the positioning port for setting and coordinating with the end difference of workpiece so that when oil sealing pushes can accurately and mounting hole
Alignment, precision are high.
3. by setting the lead and pilot hole that cooperate so that straight line pushes oil sealing all the time, is not susceptible to incline
Tiltedly, stuck phenomenon.
4. by setting press section and supporting part so that when oil sealing pushes will not run-off the straight, reliability is high.
It is pointed out that the technical concepts and features of above-mentioned preferred embodiment only to illustrate the invention, its object is to
Allow person skilled in the art to understand present disclosure and implement according to this, the guarantor of the present invention can not be limited with this
Protect scope.Any equivalent change or modification in accordance with the spirit of the invention, should all cover protection scope of the present invention it
