Description
Technical field
The present invention relates to positioning tool technical fields, more specifically, it relates to a kind of positioning pin eccentric bush.
Background technique
In engine cylinder block, cylinder head process, plane and two pits are widely used in cylinder block, cylinder head on lathe
It is positioned, positioning pin is installed with positioning pin bush(ing) cooperation.In the actual processing process, it is often necessary to quickly and accurately adjust
The geometric tolerance of whole institute's converted products, at this moment just needs to adjust positioning pin, by positioning pin according to required geometric tolerance direction into
The offset of line displacement, positioning pin can be deviated by positioning pin eccentric bush to adjust.Currently, the inner hole of positioning pin bush(ing) is all
It is through-hole, the bushing mounting holes for being used to install positioning pin bush(ing) on lathe are blind hole, position the lining on pin bush(ing) fitting machine bed
It is unfavorable for bushing after set mounting hole to quickly remove and adjust, influences production efficiency.
Summary of the invention
The technical problem to be solved by the present invention is to be directed to the above-mentioned deficiency of the prior art, the present invention provides a kind of can facilitate fastly
The positioning pin eccentric bush that speed is taken out.
The technical scheme is that a kind of positioning pin eccentric bush, including bush body, the inner hole of the bush body
One end is equipped with the closed baffle of the inner hole, and the inner hole other end is equipped with the first guide part, and the baffle is equipped with
Removal hole for dismantling the bush body out of bushing mounting holes on lathe, the removal hole are led close to described first
It is equipped with the second guide part to the one end in portion, one end periphery of the close baffle is equipped with third guide part in the bush body.
As a further improvement, the baffle is concordant with the end face of the bush body, set in the removal hole
There is screw thread.
Further, first guide part, the second guide part, third guide part are lead angle.
It further, is interference fit between the bush body and the bushing mounting holes.
It further, is clearance fit between the bush body and positioning pin.
Further, it is integrally formed structures between the bush body and baffle.
Further, one end in the bush body far from the baffle is equipped with axially arranges along the bush body
Opening.
Further, the end face of the opening from the bush body extends to the middle part of the bush body.
Beneficial effect
Compared with prior art, the present invention having the advantage that are as follows: by the way that baffle is arranged in inner hole one end, and set on baffle
Threaded removal hole is set, using bolt precession removal hole and after holding out against bushing mounting holes bottom, continues to rotate bolt for bushing
Ontology is counter to be ejected, and positioning pin eccentric bush can be effectively reduced and take out difficulty, and fast and easy takes out positioning pin eccentric bush, accelerates
It regulates the speed, saves the production time, improve productivity, guarantee product quality.
Detailed description of the invention
Fig. 1 is schematic view of the front view of the invention；
Fig. 2 is overlooking structure diagram of the invention；
Fig. 3 is left view structural representation of the invention.
Wherein: 1- bush body, 2- inner hole, 3- baffle, the first guide part of 4-, 5- removal hole, the second guide part of 6-, 7-
Three guide parts, 8- opening.
Specific embodiment
The present invention is described further for specific embodiment in reference to the accompanying drawing.
Refering to fig. 1-3, a kind of positioning pin eccentric bush, including bush body 1,2 one end of inner hole of bush body 1 is equipped with will
The closed baffle 3 of inner hole 2,2 other end of inner hole are equipped with the first guide part 4, can play good guiding when installing positioning pin
Effect facilitates positioning pin to install, and baffle 3 is equipped with to be torn open for dismantle bush body 1 in bushing mounting holes from lathe
Hole 5 is unloaded, removal hole 5 is equipped with the second guide part 6 close to one end of the first guide part 4, and baffle 3 is concordant with the end face of bush body 1,
It is equipped with screw thread in removal hole 5, is equipped with third guide part 7 close to one end periphery of baffle 3 in bush body 1, by bush body 1
Good guide effect can be played when being installed to bushing mounting holes, and bush body 1 is facilitated to install；By bush body 1 from bushing
The method dismantled in mounting hole are as follows: using bolt precession removal hole 5 and after making bolt one end hold out against bushing mounting holes bottom, continue
Bolt is rotated, bush body 1 generates upward reaction force, to be ejected bush body 1 is counter, positioning pin can be effectively reduced
Eccentric bush takes out difficulty, and fast and easy takes out positioning pin eccentric bush, accelerates to regulate the speed, and saves the production time, improves life
Yield guarantees product quality.
First guide part 4, the second guide part 6, third guide part 7 are lead angle, and structure is simple, easy to process；Bushing sheet
It is interference fit between body 1 and bushing mounting holes, is clearance fit between bush body 1 and positioning pin, can guarantee positioning accuracy,
It is integrally formed structures between bush body 1 and baffle 3, working strength is high, easily manufactured.
One end in bush body 1 far from baffle 3 is equipped with the opening 8 axially arranged along bush body 1, and opening 8 is from bushing
The end face of ontology 1 extends to the middle part of bush body 1, and setting opening 8 can make the port of bush body 1 have certain bullet
Property, it is more labor-saving during dismounting bush body 1, simultaneously as matching between bush body 1 and bushing mounting holes for interference
It closes, so that the port of bush body 1 is tightened, can reduce the fit clearance between bush body 1 and positioning pin, improve positioning accurate
Degree can be used the objects such as card and stick into after opening 8 and rotate bush body 1 when adjusting the turned position of bush body 1,
Facilitate operation.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, is not taking off
Under the premise of from structure of the invention, several modifications and improvements can also be made, these all will not influence the effect that the present invention is implemented
And patent practicability.
