Embodiment
The present invention is described further for specific embodiment in below in conjunction with the accompanying drawings.
Refering to Fig. 1-4, a kind of installation bowl-type plug of the invention and the compound punch of pin, the compound punch and jump bit 1
It is used in combination, including can be connected with jump bit 1 so that bowl-type plug 2 and pin 3 to be pressed into the drift body 5 in cylinder block 4 respectively,
Jump bit 1 hits drift body 5, drift body 5 is produced displacement, so that complete to press-fit bowl-type plug 2 and pin 3, wherein, in punching
One end of head body 5 in the inner chamber of bowl-type plug 2 and promotes its press-fit portion 7 along the axial displacement of bowl-type plug mounting hole 6 provided with pluggable,
For press-fiting bowl-type plug 2, the insertion depth of bowl-type plug 2 can be limited and can prevent by being provided with the drift body 5 of the inner side of press-fit portion 7
The stopping means 8 of the aperture of bowl-type plug mounting hole 6 damage；One end close to press-fit portion 7 on drift body 5 is additionally provided with from its end face
The blind hole 9 for being used to accommodate pin 3 of indent, the i.e. blind hole 9 are located at same one end with press-fit portion 7 vertically, for press-fiting pin 3,
The present invention is simple in construction, easy to make, and collection bowl-type plug 2 and pin 3 are installed on one, can both install bowl-type plug 2, again can be with
Pin 3 is installed, the operation for carrying out two procedures simultaneously on same production line is met, it is to avoid workman frequently changes different special
Drift, reduces labor intensity, improves production efficiency.
In the present embodiment, the locating piece 7a and diameter that its press-fit portion 7 includes being adapted with the inner chamber of bowl-type plug 2 are fixed more than this
The press-in ring 7b of position block 7a diameters, wherein, locating piece 7a is ring block, and is interference fit between bowl-type plug 2, in actual peace
During dress, first bowl-type plug 2 is plugged on locating piece 7a to avoid bowl-type plug 2 from coming off, formed between press-in ring 7b and locating piece 7a
Step surface and bowl-type plug 2 end contact, press-in ring 7b is promoted the displacement of bowl-type plug 2, also, press-in ring 7b diameter
It is adapted with the diameter of bowl-type plug mounting hole 6, makes the end face uniform force of bowl-type plug 2, axial line and the bowl-type plug of drift body 5
2 pressing direction is overlapped all the time, plays a part of guiding；Locating piece 7a ends in press-fit portion 7 are provided with falling for being circular layout
Fillet 10, is easy to locating piece 7a to insert the inner chamber of bowl-type plug 2.
Stopping means 8 include diameter be more than the diameter of bowl-type plug mounting hole 6 limited block 8a and be set in limited block 8a and
The plasticity back-up ring 8b that between press-fit portion 7 so that limited block 8a and the aperture face of bowl-type plug mounting hole 6 is isolated, wherein, limited block 8a
Play a part of the insertion depth of limitation bowl-type plug 2, back-up ring 8b is O-ring, playing prevents the slow of the aperture of bowl-type plug mounting hole 6 damage
Punching is acted on, and groove is provided between limited block 8a and press-fit portion 7, and its back-up ring 8b, which is located between limited block 8a and press-fit portion 7, to be formed
Groove in, also, back-up ring 8b step surface of the both sides respectively with limited block 8a and press-fit portion 7 fit, and anti-Sealing shield ring 8b takes off
Fall, the distance of the step surface that back-up ring 8b and limited block 8a fits to locating piece 7a end face in press-fit portion 7 is 15mm, meets bowl
Type plug 2 press-fits depth requirements, meanwhile, back-up ring 8b position is relative with the position of press-fit portion 7 and the joining place of bowl-type plug mounting hole 6
Should, it is ensured that back-up ring 8b is in contact with the aperture of bowl-type plug mounting hole 6, during bowl-type plug 2 is installed, when back-up ring 8b and bowl-type
When filling in the aperture contact of mounting hole 6, back-up ring 8b is squeezed and forms flexible contact with the aperture of bowl-type plug mounting hole 6, and works as
When back-up ring 8b is fully compressed, direction of advance progress of the limited block 8a to drift body 5 is spacing, so as to reach limitation bowl-type plug 2
The purpose of insertion depth.The present invention by designing the stopping means 8 being made up of limited block 8a and back-up ring 8b on drift body 5,
Both it can ensure that batch installed the uniformity of the insertion depth of bowl-type plug 2, limited block 8a can be avoided to damage bowl-type plug mounting hole 6 again
Aperture face, substantially increase the installation accuracy of bowl-type plug 2 and the quality of cylinder block 4.
Wherein, blind hole 9 is the blind hole being adapted with the diameter of pin 3, and depth is 9.5mm, it is ensured that each pin 3 is slotting
Enter depth unanimously, the blind hole 9 is located on the axial line of drift body 5, i.e. the axle center of the axial line of the blind hole 9 and drift body 5
Line coincides, and the power of jump bit 1 is preferably delivered on pin 3, also, is additionally provided with and the end of pin 3 in the bottom of the blind hole 9
The press-assembling surface 11 that face is adapted, the uniform force of pin 3, logical blind hole 9 and press-assembling surface 11 coordinate jointly presses pin 3
Dress, it is to avoid the frequent impact pin 3 of jump bit 1 and cause the problem of end face of pin 3 is damaged, improve pin 3 installation accuracy and
The quality of cylinder block 4.
Drift body 5 is step-like drift, and one end relative with press-fit portion 7 is provided with and drift on the drift body 5
The connected T shape shock portion 12 of body 5, the big end in the T shape shock portion 12 is connected with drift body 5, and small end is used for and impact
Hammer 1 is connected so that the rigid of whole compound punch is more preferably；Wherein, the axle of press-fit portion 7, stopping means 8 and shock portion 12
The axial line of heart line and drift body 5 coincides, and while being easy to force, the stress of bowl-type plug 2 and pin 3 can also be made more equal
It is even, so that the installation accuracy of the two is improved, also, press-fit portion 7, stopping means 8 and shock portion 12 are integrated with drift body 5
The structure of shaping, while being easy to make, also effectively increases their coaxial precision.
The shock portion 12 of the compound punch when in use, is arranged on pneumatic striking mechanism 1 by the present embodiment first, and by bowl
Type plug 2 is buckled on the locating piece 7a of drift press-fit portion 7, and the drift that will be equipped with bowl-type plug 2 is directed at the bowl-type plug mounting hole of cylinder block 4
6；The shock portion 12 that pneumatic striking mechanism 1 makes it constantly impact drift is then turned on, so that the bowl-type by bowl-type plug 2 along cylinder block 4
Plug mounting hole 6 is axially inserted into, and when back-up ring 8b contacts the aperture of bowl-type plug mounting hole 6 and is compressed, closes pneumatic striking mechanism 1,
The installation of bowl-type plug 2；Finally, one end of pin 3 is inserted in the blind hole 9 of drift, and the other end of pin 3 is directed at cylinder
The pin-and-hole of body 4, is again started up the shock portion 12 that pneumatic striking mechanism 1 makes it constantly hit drift, so that by pin 3 along cylinder block 4
Pin-and-hole be axially inserted into, when pin 3 push up bottom when, the installation of pin 3.The compound punch of the present invention, operative employee need to only use one
Planting drift just can realize the general installation of bowl-type plug 2 and pin 3, reduction labor intensity, raising operating efficiency.In addition, such a punching
The flexible spacing structure of headband, both can guarantee that the uniformity for tapping depth, can also ensure that the surface of cylinder block 4 is not destroyed, so that
Improving The Quality of Products.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art,
Without departing from the structure of the invention, several modifications and improvements can also be made, these are implemented all without the influence present invention
Effect and practical applicability.
