Abstract
The invention relates to a structure of a combined type positioning pin, in particular to a positioning pin for fastening and positioning two parts of which the planes are contacted with each other to prevent the two parts from moving relative to each other. The combined type positioning pin comprises a nut, a gasket and a taper pin, wherein one end of the taper pin is sequentially provided with the gasket and the nut, and the other end of the taper pin is sequentially provided with a second gasket and an inner hexagon screw; and relative positions between the taper pin and a part are fixed through the nut and the inner hexagon screw. The combined type positioning pin consists of basic and common parts and is easy to manufacture; and the hollow taper pin with the taper degree of 1:30 is matched with a reamed hole, so that the combined type positioning pin is low in requirement of machining accuracy of pin holes, accurately and firmly positioned and convenient to mount, can be assembled and disassembled repeatedly and does not damage engine bodies.
Description
Technical field
The present invention relates to a kind of combined type locating pin structure, specifically relate to a kind of component that are used for two plane contact in fastening location, thereby prevent the locating stud of the relative play of two component.
Background technique
Along with the overall development of modern mechanical industry, also increasingly high to the assembling and positioning requirement of component of machine.Utilization is threaded, key connects, the securing dowel of straight pin or the like mode is more common, but the research of combined type locating stud still remains to be carried out.
Straight pin and taper pin can play fastening positioning action; In a single day but when receiving bigger impact; Becoming flexible can appear in straight pin or taper pin; Therefore to the extra high component of some required precisions,, be necessary to develop a kind of combined type locating stud that not only can locate but also can realize fastening effect if only fix poor effect by bolt.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing locating stud, guarantee that the faying surface of two component in assembly process does not have relative play, and make the combined type locating pin structure that two faying surfaces fit tightly.
According to technological scheme provided by the invention, the combined type locating pin structure comprises nut, packing ring, taper pin; Characteristic is: said taper pin one end is disposed with packing ring and nut, and the said taper pin the other end sets gradually second packing ring and socket head screw, through the fixing relative position of taper pin and part of nut and socket head screw.
Be provided with the rubber ring that is used for screens between said nut and the taper pin.Said taper pin is a hollow.
The present invention has following advantage:
Combined type locating stud of the present invention is made up of basic common part, makes simple.Tapering open circles taper pin through 1:30 cooperates with the strand drilling, and the requirement on machining accuracy empty to pin is low, and accurate positioning is firm, and is easy for installation, can realize repeatedly installing and removing, and not damage body.Its Location accuracy is higher than straight pin, but therefore self-locking when receiving transverse force not only can realize reaching the purpose of location, also can avoid the careless omission of mounting point or anisotropy.
This combined type locating stud can bear bigger axial force, can be used for the occasion of serious vibration and impulsive load, all the other fixing pins that are superior to selling on the market.
Description of drawings
Fig. 1 structure user mode of the present invention figure.
Embodiment
As shown in Figure 1, the combined type locating stud comprises nut 1, packing ring 2, taper pin 4; Taper pin 4 pins are gone in the part hole to be fixed, and said taper pin 4 one ends are disposed with packing ring 2 and nut 1, and taper pin 4 is a hollow, and said taper pin 4 the other ends set gradually second packing ring 6 and socket head screw 7; Through the fixing relative position of taper pin 4 and part of nut 1 and socket head screw 7.
Be provided with the rubber ring 3 that is used for screens between said nut 1 and the taper pin 4.
When the combined type locating stud was installed and used, taper pin 4 was an interference fit with component 5 endoporus, through tightening socket head screw 7 component 5 is fitted tightly.With taper pin 4 cooperate with the hole of component 5 install after, socket head screw 7 is cover upper gaskets 6 earlier, the socket head screw 7 that will overlap packing ring again passes the endoporus of taper pin 4, on socket head screw 7, puts a rubber ring 3 again and clamp-ons in the hole of component 5.Afterwards; On hex screw 7, add a packing ring 2, the nut 1 of screwing on, the effect meeting through 1 pair of packing ring 2 of nut will be fitted on the taper pin 4 to rubber ring 3; After tightening up nut 1; Can be under the squeezing action of rubber ring 3, taper pin 4 can form interference fit with the hole, thereby reaches location and fastening requirement.When impacting generation, rely on the effect of taper pin 4, can prevent the relative play of two component, and add the fastening effect of screw, make the fastening location of two component reach optimization.
Claims (3)
1. the combined type locating pin structure comprises nut (1), packing ring (2), taper pin (4); It is characterized in that: said taper pin (4) one ends are disposed with packing ring (2) and nut (1), and said taper pin (4) the other end sets gradually second packing ring (6) and socket head screw (7).
2. combined type locating pin structure according to claim 1 is characterized in that: be provided with the rubber ring (3) that is used for screens between said nut (1) and the taper pin (4).
