Abstract
The utility model discloses a kind of novel quick change entirety positioning pins, including dowel body, positioning bolt, the dowel body incidence is cone, two sides are provided with twice threaded hole along the vertical direction, the outwardly convex round pin out in bottom, the threaded hole is more bigger than positioning bolt, and positioning bolt matches with the fixing screwed hole size in tool base plate.The utility model locating pin structure is simple, stable and firm, it can be achieved that be switched fast product, greatly improves working efficiency.
Description
Technical field
The utility model relates to a kind of positioning pin, in particular to the whole positioning pin of a kind of quick-changing type.
Background technique
Currently, being that tooling ontology is compatible, leading to when shell Cutter Body Processing with Machining Center clutch housing is related to multiple production switch
The Product Process hole positioning pin and pressing plate crossed on switching tooling ontology are realized.Since product is batch production, technique it requires
Hole positioning pin precision is high, stability is strong.Prior art hole positioning pin is seperated positioning pin, when installation, is needed location key seat bottom
Portion's round pin and the bottom plate location hole of tooling are combined together, then cross the base thread of wire hole and tooling by location key seat with bolt
Hole fastening, then cooperates positioning pin and location key seat head bore, from key seat side with screw locking is only consolidated, forms secondary match
It closes, and location key seat incidence elongated strength is not easily-deformable enough, so positioning accuracy and stability are poor.When switching product is work
When the seperated location key seat of dress removes, bolt is come loose, since the bottom plate location hole of seperated positioning pin bottom round pin and tooling was
Cross cooperation, often seperated location key seat bottom round pin is stuck in bottom plate location hole, remove it is difficult time-consuming and laborious, sometimes through tearing open
Lower tool base plate or the precision for beaing and influencing by force seperated location key seat and bottom plate location hole with hammer.To influence switching section
It claps.
Summary of the invention
The purpose of this utility model is to provide a kind of novel quick change entirety positioning pins, to overcome current frequent switching seperated
The problems such as positioning accuracy of positioning pin is low, stability is poor, service life is short, switching time is long, cost of manufacture is high is finally reached fast
Speed switching product, steady production improve entire processing efficiency.
A kind of novel quick change entirety positioning pin, including dowel body, positioning bolt, it is characterised in that：The positioning pin
Ontology incidence is cone, and two sides are provided with twice threaded hole, the outwardly convex round pin out in bottom, the screw thread along the vertical direction
Boring ratio positioning bolt is bigger, and positioning bolt matches with the fixing screwed hole size in tool base plate.
Further, the bottom round pin sidewalls vertical direction of the dowel body is provided with an air channel.
The utility model positioning pin and location key seat unify body, and original seperated positioning pin is changed to whole positioning pin and is reduced
Elongated cylindrical incidence is changed to cone and increases intensity, the mistake wire hole of whole positioning pin pedestal is changed to ratio by primary cooperation
The bigger threaded hole of bolt, except the seperated location key seat centre drill venthole that disappears, in whole positioning pin bottom, round pin is opened one and is led to
Air drain.
The utility model has the technical effect that：Because bolt is smaller than threaded hole when installing whole positioning pin, entirety can be passed through
Positioning pin base threaded hole and tool base plate threaded hole are fastenedly connected；When removing, come loose hold-down bolt, screw on bigger bolt and
Whole positioning pin connection, can be extracted whole positioning pin with pin removal.Structure is simple, is easier to realize, low in cost, improves
Working efficiency.

Fig. 2 is that the utility model quick change entirety positioning pin extracts usage state diagram；
Icon in figure：1, dowel body, 2, positioning bolt, 3, tool base plate, 4, bigger bolt, 5, round pin, 6, logical
Air drain.
Specific embodiment
The embodiment for structure that according to the present invention will be described in detail below with reference to the accompanying drawings：
It as shown in Figure 1 include dowel body 1, positioning bolt 2,1 incidence of dowel body is cone, two sides
It is provided with twice threaded hole along the vertical direction, the outwardly convex round pin 5 out in bottom, the threaded hole is more bigger than positioning bolt, fixed
Position bolt 2 matches with the fixing screwed hole size in tool base plate 3.For convenience of extract positioning pin, the dowel body
Bottom round pin sidewalls vertical direction is provided with an air channel 6.Whole positioning pin is installed because positioning bolt 2 is smaller than threaded hole, is determined
Position bolt 2 can be fastenedly connected by the threaded hole of threaded hole and tool base plate 3 in dowel body 1；When removing, come loose positioning
Bolt 2, screws on bigger bolt 4 and dowel body 1 connects, and can be extracted dowel body 1 with pin removal.
Original seperated positioning pin is changed to whole dowel body reduction and once matched by the utility model quick change entirety positioning pin
It closes, except positioning pin and the side only screw installation and removal admittedly of having disappeared, improves quick change beat.Elongated cylindrical incidence is changed to circle
Taper avoids location key seat elongated cylindrical incidence intensity from not enough deforming, and increases intensity and prolongs the service life.It will be original seperated
The mistake wire hole of positioning pin pedestal is changed to threaded hole more bigger than bolt, and when installation can keep original and cross wire hole function, and disassembly is variable
At the threaded hole of installation pin removal, the disassembly difficult time is reduced.Except the seperated location key seat centre drill venthole that disappears, in whole positioning
Pin bottom round pin side wall opens an air channel, facilitates installation, reduces production drilling deep hole difficulty, is changed to solid increase by force by hollow
Degree.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
For personnel, make several equivalent substitute or obvious modifications without departing from the concept of the premise utility, and performance or
Purposes is identical, then shall be regarded as belonging to the protection scope that claims that the utility model is submitted determine.
