Description
Technical field
The invention belongs to field of mechanical technique, in particular to a kind of structure improved locating shaft.
Background technique
Locating shaft is commonly to position tool in machining, very widely used in machining, common positioning
Axis is usually used the mode of plugging and is installed on part of appliance, then by fasteners such as corresponding nut or clips that it is tight
Gu this not only installs trouble, but also installer easily forgets to pacify to locating shaft in heavy installation exercise on part of appliance
Loading nut or clip, thus there are security risk, Yi Fasheng safety accident.
Summary of the invention
The purpose of the present invention is there is the above problem in view of the prior art, it is simple, practical to propose a kind of structure
Structure improved locating shaft.
Object of the invention can be realized by the following technical scheme: a kind of structure improved locating shaft, including is linked as one
The head of body and shank, the outer diameter on head are greater than the outer diameter of shank, which is characterized in that along diameter on the two opposite lateral walls of shank
Offer symmetrically arranged counterbore to direction, be connected between two counterbores by through-hole and the aperture of through-hole be less than counterbore hole
Diameter is equipped with spring in through-hole and is fixed on the latch segment of both ends of the spring, and latch segment is by the interconnecting piece being linked together and locking
Portion's composition, interconnecting piece are inserted in through-hole, and the outer diameter of tight lock part is greater than through-hole aperture, and tight lock part a part is located in counterbore simultaneously
There is gap between counterbore base, tight lock part another part, which stretches out counterbore and has on the tight lock part side wall of the part, to be imported
Face can be such that tight lock part is entirely retracted to counterbore when tight lock part stress, offer oilhole and oilhole along axis direction in shank
Head upper end face is passed straight through to, several equally distributed oil grooves are in axial direction offered on the side wall of shank and oil groove and oilhole
It is communicated by oil duct.
Compared with prior art, the present invention on shank by opening up counterbore and through-hole, and the corresponding configuration in through-hole
There is latch segment, when locating shaft is during being inserted into part of appliance axis hole, latch segment, which is squeezed, to be moved inward until being entirely retracted to
To counterbore, locating shaft can smoothly pass through axis hole at this time, after latch segment is by axis hole, under the effect of spring force, lock
Tight block restores to initial position and is resisted against on box end, to cooperate enable locating shaft to consolidate to plug together with head
In pin hole, without other fastenings, assembler locating shaft need to be only inserted into pin hole can make this locating shaft with
Part of appliance is fastenedly connected, easy to use, assembly is simple, while shank opens up connected oil-through-hole and oil groove, and lubricating oil is from oilhole
It flows at oil groove, thus when installing locating shaft to part of appliance, between locating shaft and the metal object of its connection
Contact surface has remained lubricating oil, avoids locating shaft and gets rusty and be difficult to the problem of dismantling.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
In figure, 1, head；2, shank；21, counterbore；22, through-hole；23, oilhole；24, oil groove；25, oil duct；3, latch segment；

Specific embodiment
Following is a specific embodiment of the present invention in conjunction with the accompanying drawings, technical scheme of the present invention will be further described,
However, the present invention is not limited to these examples.
As shown in Figure 1, this structure improved locating shaft includes the head 1 being linked together and shank 2, the outer diameter on head 1 is big
In the outer diameter of shank 2, symmetrically arranged counterbore 21, two counterbores are radially offered on the two opposite lateral walls of shank 2
Between 21 by through-hole 22 be connected and the aperture of through-hole 22 be less than counterbore 21 aperture, be equipped in through-hole 22 spring 4 and
It is fixed on the latch segment 3 at 4 both ends of spring, latch segment 3 is made of the interconnecting piece 31 and tight lock part 32 being linked together, and interconnecting piece 31 is inserted
In through-hole 22, the outer diameter of tight lock part 32 is greater than 22 aperture of through-hole, and 32 a part of tight lock part be located in counterbore 21 and with it is heavy
There is gap, 32 another part of tight lock part stretches out counterbore 21 and has on 32 side wall of the tight lock part of the part between 21 bottom of hole
Approaching face 33 can be such that tight lock part 32 is entirely retracted to counterbore 21 when 32 stress of tight lock part, open up in shank 2 along axis direction
There is oilhole 23 and oilhole 23 passes straight through to 1 upper surface of head, several be uniformly distributed in axial direction is offered on the side wall of shank 2
Oil groove 24 and oil groove 24 and oilhole 23 communicated by oil duct 25.
It is corresponding configured with latch segment 3 by opening up counterbore 21 and through-hole 22 on shank 2, and in through-hole 22, when fixed
During being inserted into part of appliance axis hole, latch segment 3 is squeezed to be moved inward up to being entirely retracted to counterbore 21 position axis, this
When locating shaft can smoothly pass through axis hole, in latch segment 3 by the way that after axis hole, under the action of 4 elastic force of spring, latch segment 3 restores
To initial position and it is resisted against on box end, thus cooperate what locating shaft was consolidated to be inserted in pin hole together with head 1,
Without other fastenings, locating shaft need to be only inserted into pin hole by assembler can make this locating shaft and part of appliance
It is fastenedly connected, easy to use, assembly is simply.
Shank 2 opens up connected oil-through-hole 23 and oil groove 24 simultaneously, and lubricating oil flows into from oil groove 24 from oilhole 23, thus
When locating shaft is installed to part of appliance, the contact surface between locating shaft and the metal object of its connection has remained lubrication
Oil avoids locating shaft and gets rusty and be difficult to the problem of dismantling.
Specific embodiment described herein is only an example for the spirit of the invention.The neck of technology belonging to the present invention
The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method
In generation, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
