Abstract
A kind of quick change alignment pin, is provided with the cylindrical shaft shoulder for connected positioning plate including Cylindrical locating pins body, dowel body middle-end；Dowel body is divided into the upper location division being positioned at above the shaft shoulder and is positioned at the lower location division below the shaft shoulder by the shaft shoulder, and the diameter of lower location division is more than upper location division；1 is had to have the V-groove for coordinating with the head of screw of sunk screw with screwing via, screw via on the shaft shoulder；Having screw via on location-plate, the lower location division of dowel body and the screw via interference fits on location-plate, dowel body is fixed on location-plate by sunk screw.This utility model changes fast and easy, and repetitive positioning accuracy is high, improves work efficiency, reduces cost；And there is higher rigidity, be unlikely to deform, there is longer service life.
Description
Technical field
This utility model relates to a kind of clamp device, is specifically related to a kind of quick change alignment pin.
Background technology
In the course of processing of component of machine, generally using common alignment pin, its one end is fixed in location-plate, separately
One end is used for positioning workpiece, and owing to the hardness of alignment pin is the highest, and alignment pin is and location-plate interference fit, is difficult to
Dismounting；Additionally in unloading process by force, stress suffered by the end of alignment pin is relatively big, easy fracture, and right and wrong removed by the alignment pin of fracture
The most difficult.Problem above causes that processing cost is high, working (machining) efficiency is low.
Summary of the invention
The purpose of this utility model be to overcome the above-mentioned deficiency of prior art and provide a kind of simple in construction, user
Just quick change alignment pin, it changes fast and easy, repetitive positioning accuracy height；And there is higher rigidity so that alignment pin is not
Yielding, there is longer service life.
The technical solution of the utility model is:
It is provided with the cylindrical shaft shoulder for connected positioning plate including Cylindrical locating pins body, dowel body middle-end；Institute
State the shaft shoulder and dowel body be divided into the upper location division being positioned at above the shaft shoulder, and be positioned at below the shaft shoulder for on location-plate
The lower location division of screw via interference fits, the diameter of lower location division is more than upper location division；1 is had with screwing on the described shaft shoulder
Via, screw via has the V-groove for coordinating with the head of screw of sunk screw.
Described screw via has 4, is evenly distributed on the shaft shoulder.
The top end face of described sunk screw and shaft shoulder upper surface are at same plane.
Described shaft shoulder upper surface and location-plate upper surface are at same plane.
The cross section of described dowel body and the cross section of the shaft shoulder are concentric circular, and the diameter of the cross section of the shaft shoulder is big
Diameter in the cross section of dowel body.
The beneficial effects of the utility model are: this utility model changes fast and easy, and repetitive positioning accuracy is high, improves
Work efficiency, reduces cost；And there is higher rigidity, be unlikely to deform, there is longer service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is top view of the present utility model.
Fig. 3 is working state figure sectional view of the present utility model.
Detailed description of the invention
Dowel body 2 is divided into the upper location division being positioned at above the shaft shoulder 4 as it is shown in figure 1, the shaft shoulder 4 is positioned at and is positioned at the shaft shoulder
Lower location division below 4, the diameter of lower location division is more than upper location division；The shaft shoulder 4 both sides are respectively arranged with 1 screw via 5, screw via
5 have the V-groove for coordinating with the head of screw of sunk screw 3.
As in figure 2 it is shown, dowel body 2 cross section is circular, the shaft shoulder 4 cross section be circle, dowel body 2 transversal
The cross section of face and the shaft shoulder 4 is concentric circular, and straight more than the cross section of dowel body 2 of the diameter of the cross section of the shaft shoulder 4
Footpath.Screw via 5 has 4, is evenly distributed on the shaft shoulder 4.
As it is shown on figure 3, have screw via on location-plate 1, the lower location division of dowel body 2 and the spiral shell on location-plate 1
Nail via interference fits, dowel body 2 is fixed on location-plate 1 by sunk screw 3.The top end face of sunk screw 3 and axle
Take on 4 upper surfaces at same plane.The shaft shoulder 4 upper surface and location-plate 1 upper surface are at same plane.Fill respectively in 4 screw vias 5
Being furnished with cross recessed countersunk head sscrew 3, dowel body 2 is fixed on location-plate 1 by 4 cross recessed countersunk head sscrews 3.This practicality is new
Interference fits between type and location-plate 1, upper location division of the present utility model is used for positioning workpiece to be processed.
