Property gasket 132 radially on distance, prevent the positioning pin 1 by diameter adjustment after being detached from guide section 11, due to steel cable
133 length is too short, and elastomeric pad 132 can not be restored under natural conditions, causes 132 breakage of elastomeric pad that cannot continue to make
With.
As shown in figure 5, outermost elastomeric pad 132 is equipped with a circle rigid projection 134, each rigid projection 134 is along week
To equidistantly distributed, and each rigid projection 134 is along the axial direction setting of elastomeric pad 132.Rigid projection 134 in the present embodiment
Cross section is right-angled trapezium.It should be noted that：The utility model on outermost elastomeric pad 132 by being arranged circle etc.
The rigid projection 134 of spacing distribution is conducive to the wear resistance and intensity that improve positioning pin 1, prevents positioning pin 1 by long-term use
After process, surface generates scratch and scraps to serious wear, improves the service life of positioning pin 1；Meanwhile when single rigid projection
After 134 damages, it is only necessary to replace damaged rigid projection 134, without integral replacing, reduce maintenance cost and
Increase the convenience of maintenance.It should be further noted that：Since the cross section of rigid projection 134 in the utility model is straight
Angle is trapezoidal, so positioning section 13 is from top to bottom, the diameter of outer surface is first gradually increased, after remain unchanged, diameter is gradually increased
Part has been used for secondary guiding role, and diameter remains unchanged part for playing the role of positioning, and diameter is gradually increased the cone of part
Degree is greater than the taper of guide section 11, is conducive to that the positioning to plate is rapidly completed.
Specifically in the present embodiment, the outside of rigid carrier 131 is disposed with one layer of steel disc 135 and two layers of elastomeric pad
132, and have 8 layers of steel cable 133 along axial spaced set in the space of outermost layer elastomeric pad 132 and rigid carrier 131, every layer
It include 12 steel cables 133.It should be noted that：In the present invention number of plies of the quantity of elastomeric pad 132 and steel cable 133 and
The design of quantity, so that elastomeric pad 132, when radially contracted, the contraction speed of elastomeric pad 132 in the axial direction keeps one
It causes, guarantees the stability and accuracy of 1 diameter adjustment of positioning pin.
As shown in fig. 6, fixed section 12 includes fixed section ontology 121, fixed section ontology 121 is cylindrical structure, this is fixed
L-type notch 1211 is offered on the side of Duan Benti 121.It should be noted that：The utility model passes through L-type notch 1211 and pressure
The cooperation of key can guarantee that positioning pin 1 will not rotate in die positioning pin mounting hole.Specifically installation process is：It will consolidate
Determine section ontology 121 to be inserted into die positioning pin mounting hole, then key will be pressed to be against on L-type notch 1211 by screw, to protect
Card positioning pin 1 will not rotate.
The upper end of fixed section ontology 121 is provided with the interconnecting piece 122 of cylindrical structure, the axis of the fixed section ontology 121
The central axes of line and interconnecting piece 122 are located on the same line, and the diameter of interconnecting piece 122 is less than the diameter of fixed section ontology 121,
The top of the interconnecting piece 122 passes through above-mentioned rigid carrier 131 and is inserted into above-mentioned circular trough 112, and the periphery of insertion portion is set
It is equipped with the first gear 1221 matched with above-mentioned second gear 1121, the tooth of the first gear 1221 and second gear 1121
Engagement is one flank gearing, and the lower end surface of above-mentioned positioning section 13 is located on fixed section ontology 121.It should be noted that：This is practical new
The top of interconnecting piece 122 contacts or the top of rigid carrier 131 and the first toroidal cavity 113 with 112 bottom of circular trough in type
Bottom contact or the top of interconnecting piece 122 contacted with 112 bottom of circular trough and the top of rigid carrier 131 and the first annulus
The bottom of connected in star 113 also contacts.
Specifically in the present embodiment, the second toroidal cavity is offered on the outer ring of fixed section ontology 121, second annulus
The central axes of connected in star and the central axes of fixed section 12 coincide, and the second circular ring shape is inserted into the lower part of above-mentioned rigid carrier 131
