Description
Technical field
The utility model is related to a kind of special auxiliary machining tools arts, and in particular to a kind of positioning pin pulls up work
Tool.
Background technology
In some mechanical processings and upkeep operation of transmission, it is often required to use positioning pin and is positioned, after fulfiling assignment,
These positioning pins is then needed to be extracted.Way in no special puller, usually in rod pieces such as screwdrivers
A screw is welded in front end, then by screw precession positioning pin, then with the tail portion of the rod pieces such as hammer screwdriver, most
Positioning pin is extracted afterwards.The rod pieces such as discontinuity during due to beaing, screwdriver are easy to damage, time-consuming and laborious, it is also possible to
Damage the processing workpiece that protect.
Likewise, in some mechanical equipment assembling process high to precision requirement, need to reach by positioning pin
The purpose of positioning.At this point, Cylindrical locating pins are common positioning pins, and traditional method operating personnel are to borrow iron hammer and rapping
The tools of grade installation Cylindrical locating pins, sometimes will be inappropriate due to the placed angle of rapping and cause location hole fixed to cylinder
Position pin generates " splitting " phenomenon, the Cylindrical locating pins by " splitting " is at this moment just needed to pull out, the Cylindrical locating pins more renewed.
At this time, it is necessary to ensure that location hole is not destroyed, common practices is that operating personnel use locking pliers by the cylinder of " splitting " at this time
Shape positioning pin is pulled out.But pulling out Cylindrical locating pins using locking pliers can cause high effort for, and the palm of operating personnel is also brought along
Certain injury.
Application number 201520132503.4, Authorization Notice No. CN 204566028 U are entitled " to pull out cylindrical positioning
The patent document of the easy device of pin " discloses a kind of patent：" including main body, flange and sliding sleeve, the main body includes hand
Handle, baffle and guide rod, the rear end of the flange are fixedly connected with the front end of the guide rod, and the front end of the flange carries and cylinder
The identical internal thread hole of shape positioning pin diameter, the sliding sleeve are slideably sleeved on the guide rod, and the rear end of the guide rod is consolidated
Dingan County fills the baffle, and the baffle is connect with handle." designer thinks, the utility model provide it is a kind of it is easy to operate, save
Shi Shengli, it effectively avoids generating the easy device for pulling out Cylindrical locating pins destroyed to location hole.But it is considered that it exists
The problem of applicability is not wide.
Likewise, application number 201320200084.4,203185262 U of Authorization Notice No. CN, entitled " one kind is fixed
The patent document of position pin puller " discloses a kind of patent：" it is made of slide bar, sliding block and connector of pulling pin, close on slide bar
Tail portion is equipped with block, and slide block set is on slide bar and can have screw hole along sliding bar, slide bar head end, and connector of pulling pin is by two screw rods pair
It connects, one end screw rod precession slide bar head end screw hole, in other end screw rod precession positioning pin, connector of pulling pin is connected by with positioning pin
Screw size difference have plurality of specifications, connect and be replaced with slide bar." utility model use when first by slide block set in cunning
On bar, then the connector one end that will pull pin is connected on slide bar, and the other end is connected in positioning pin, final force sliding slider, impact
Block on slide bar achievees the purpose that extract positioning pin, and by selecting the connector of pulling pin of different size that can extract not
Time saving and energy saving with the positioning pin of size, working efficiency is high.The latter utility model patent has than previous utility model patent more
Big applicability, but it is not suitable for the extraction operation of minor diameter positioning pin.
