Abstract
The utility model discloses a kind of pin removals, it is made of pedestal (2), bayonet (3), plane bearing (4), nut of pulling pin (5), bolt (6), it is characterized by: being equipped with nut of pulling pin (5) on pedestal (2), it is equipped on nut of pulling pin (5) plane bearing (4), plane bearing (4) is equipped with bolt (6) above.The utility model friction is small, can easily extract threaded positioning pin, reach time saving and energy saving, quickly extracts the purpose of positioning pin.
Description
Technical field
The utility model relates to the extracting tool of positioning pin, especially a kind of pin removal for pulling out threaded positioning pin.
Background technique
There is a kind of threaded positioning pin (such as big bearing block positioning pin) in existing equipment positioning pin, is dismantling the positioning
It can be limited because of working environment when pin, only can be used on steel plate and punch, passed through from hole with bolt, steel plate is padded, use spanner
Wrenching bolt is extracted positioning pin using the pulling force that bolt thread enters positioning pin, time-consuming since the friction of bolt and steel plate is big
Arduously, screw rod bending or switch out could not also usually be extracted positioning pin.
Summary of the invention
A kind of friction provided the purpose of the utility model is to overcome disadvantages mentioned above is small, can easily will be threaded
Positioning pin is extracted, and reaches time saving and energy saving, quickly extracts the purpose of positioning pin.
It the utility model aim and solves its technical problem underlying and adopts the following technical solutions to realize:
A kind of pin removal is made of, it is characterised in that: on the base pedestal, bayonet, plane bearing, nut of pulling pin, bolt
Face is equipped with nut of pulling pin, and plane bearing is equipped on nut of pulling pin, is equipped with bolt above plane bearing.
The screw rod of the bolt lower part passes through plane bearing, nut of pulling pin connects positioning pin.
The pedestal inner face is equipped with threaded hollow nut of pulling pin by screw thread.
There is the screw thread with detent fit on the bolt.
Bayonet is provided on the pedestal.
The positioning pin is mounted on key seat.
The utility model compared with the existing technology has clear advantage and beneficial effect.From the above technical scheme,
Nut of pulling pin is installed by face on the base, plane bearing is installed on nut of pulling pin, is equipped with above plane bearing
Bolt.It realizes and reduces frictional force using plane bearing, plane bearing 4 can prevent bolt from following nut rotation of pulling pin, can be light
Threaded positioning pin is extracted, reach time saving and energy saving, quickly extract positioning pin purpose.
Detailed description of the invention
Fig. 1 is the utility model structure diagram；
Fig. 2 is the utility model top view；
Fig. 3 is the cross-sectional view of Fig. 2A-A.
1. key seat of label in figure, 2. pedestals, 3. bayonets, 4. plane bearings, 5. pull pin nut, 6. bolts, 7. positioning pins.
Specific embodiment
As shown in Figure 1-3, a kind of pin removal, is made of pedestal 2, bayonet 3, plane bearing 4, nut 5 of pulling pin, bolt 6,
Be characterized in that: face is equipped with nut 5 of pulling pin on the base 2, and plane bearing 4, plane bearing 4 are equipped on nut 5 of pulling pin
Bolt 6 is installed above.
The screw rod of 6 lower part of bolt passes through plane bearing 4, nut 5 of pulling pin connects positioning pin 7.
2 inner face of pedestal is equipped with threaded hollow nut 5 of pulling pin by screw thread.
There is the screw thread cooperated with positioning pin 7 on the bolt 6.
Bayonet 3 is provided on the pedestal 2.
The positioning pin 7 is mounted on key seat 1.
In use, bolt 6 is rotated into positioning pin 7, it is threadedly coupled bolt 6 and positioning pin 7, blocks bayonet with spanner
3, nut 5 of pulling pin is being rotated counterclockwise with spanner, and nut 5 of pulling pin stretches upwards out of pedestal 2, and plane bearing 4, bolt 6 are pushed up
Firmly stretching, extension upwards, pulls positioning pin 7 to stretch upwards, extracts positioning pin 7.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation, it is any without departing from the content of the technical scheme of the utility model, according to the technical essence of the utility model to above embodiments
Made any simple modification, equivalent change and modification, are still within the scope of the technical solutions of the present invention.
