Description
Technical field
The present invention relates to apply required pin shaft positioning product field, and in particular to a kind of fast self-fastening positioning pin.
Background technique
Positioning pin participates in the part of limited object freedom degree, there is certain application in the equipment of some mechanical movements,
The position for being mainly used for two-dimensional space determines.When body is coupled by multiple parts, and various pieces need to be in process and assemble
When keep exact position when, should using positioning finger setting.If dissection type cabinet is made of cover and base, upper bearing aperture adds
Work required precision with higher, therefore in design, two positioning pins apart from each other should be set on split surface, to guarantee
Its process and assemble precision.The pin that market uploads is unable to self-tightening and using relatively cumbersome.
Summary of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of fast self-fastening positioning pin, its energy
Enough quickly positioning and self-tightening, with more flexible and convenient compared to conventional locating pins.
To achieve the above object, the present invention is using following technical scheme: it includes bayonet lock casing, bolt mandrel, plug
Guide sleeve, gasket, spring, steel ball, bolt mandrel mounting hole, spring groove, steel ball limiting slot, guiding grooving；The installation of bolt mandrel
Hole and guiding grooving are provided with bayonet lock inside pipe casing, and spring groove is provided with inside bolt mandrel, and spring is arranged in spring groove；Steel ball
Limiting slot is provided on bayonet lock casing, and bolt mandrel is inserted into bolt mandrel mounting hole, and plug guide sleeve is caught in by gasket leads
Into grooving, steel ball is arranged inside steel ball limiting slot.
The right half part of the bolt mandrel is ramp structure.
The quantity of the steel ball limiting slot is two.
The bayonet lock casing is that steel machine adds integrated molding.
The plug guide sleeve is PE plug guide sleeve.
The gasket is nylon spacer.
The working principle of the invention: bayonet lock casing by with bolt mandrel, plug guiding, nylon spacer, spring, snap ring,
Steel ball is cooperatively connected, and by pressing bolt mandrel, compressed spring, the steel ball inside steel ball limiting slot passes through the slope of bolt mandrel
It is shunk, is made in fast self-fastening positioning pin load hole, then unclamp bolt mandrel, spring-return makes bolt mandrel appliance for releasing single
Out, steel ball automatic ejection is stuck in the steel ball limiting slot of hole, to achieve the effect that quickly positioning and self-tightening.
After adopting the above technical scheme, the invention has the following beneficial effects: it can quickly be positioned and self-tightening, with compared to tradition
Positioning pin is more flexible and convenient.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention without any creative labor, may be used also for those of ordinary skill in the art
To obtain other drawings based on these drawings.
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the left view of corresponding diagram 1.
Description of symbols: bayonet lock casing 1, bolt mandrel 2, plug guide sleeve 3, gasket 4, spring 5, steel ball 6, bolt core
Shaft mounting hole 7, spring groove 8, steel ball limiting slot 9, guiding grooving 10.
Specific embodiment
Referring to shown in Fig. 1-Fig. 2, present embodiment the technical solution adopted is that: it includes bayonet lock casing 1, bolt core
Axis 2, plug guide sleeve 3, gasket 4, spring 5, steel ball 6, bolt mandrel mounting hole 7, spring groove 8, steel ball limiting slot 9, guide sleeve
Slot 10；Bolt mandrel mounting hole 7 is provided with 1 inner hub location of bayonet lock casing, and guiding grooving 10 is provided with inside bayonet lock casing 1
Center left end, spring groove 8 is provided with inside bolt mandrel 2, and spring 5 is arranged in spring groove 8；9 connecting bolt core of steel ball limiting slot
Shaft mounting hole 7 is simultaneously provided on bayonet lock casing 1, and steel ball limiting slot 9 is located at 1 right half part of bayonet lock casing；The spring of bolt mandrel 2
8 end face of slot is inserted into bolt mandrel mounting hole 7, and plug guide sleeve 3 is caught in guiding grooving 10 by gasket 4, and the setting of steel ball 6 exists
Inside steel ball limiting slot 9.
The right half part of the bolt mandrel 2 is ramp structure, and the position of ramp structure corresponds to opening for steel ball limiting slot 9
If position.
The quantity of the steel ball limiting slot 9 is two, and two opposition of steel ball limiting slot 9 are arranged on bayonet lock casing 1.
The bayonet lock casing 1 is that steel machine adds integrated molding.
The plug guide sleeve 3 is PE plug guide sleeve.
The gasket 4 is nylon spacer.
The working principle of the invention: bayonet lock casing by with bolt mandrel, plug guiding, nylon spacer, spring, snap ring,
Steel ball is cooperatively connected, and by pressing bolt mandrel, compressed spring, the steel ball inside steel ball limiting slot passes through the slope of bolt mandrel
It is shunk, is made in fast self-fastening positioning pin load hole, then unclamp bolt mandrel, spring-return makes bolt mandrel appliance for releasing single
Out, steel ball automatic ejection is stuck in the steel ball limiting slot of hole, to achieve the effect that quickly positioning and self-tightening.
After adopting the above technical scheme, the invention has the following beneficial effects: it can quickly be positioned and self-tightening, with compared to tradition
