Description
Technical field
The present invention relates to extracting tool fields, and in particular to a kind of pin removal.
Background technology
Prospect in Modern Auto Manufacture Industry is guarantee dress in these equipments commonly using diel, welding fixture, tooling cubing
Standby precision can use straight pin to carry out positioning assembly to component and the component on equipment, and the straight pin on component and component
On hole require to be that transition coordinates, want to further take out after straight pin assembly come it is extremely difficult, traditional split-pin device be by with straight pin
The bolt of internal thread size twists into straight pin, then welds the axis in a flanged face, what intermediate sleeve one can slide up and down
Set, it is desirable that the weight of set is identical as iron hammer weight, when pulling pin, slides the flange face on impacting shaft repeatedly using the set on axis,
To achieve the purpose that this pin removal operation is comparatively laborious, and scene need to prepare welding machine, prepare different model by straight pin extraction
, easily there is the problems such as weld cracking, bolt falls off with axis in bolt, and axis and poor reliability after bolt welding.
Invention content
For pin removal use reliability, working efficiency is improved, the present invention proposes that a kind of reliability is high, easy to use, raw
Produce efficient pin removal.
The technical scheme is that, a kind of pin removal, including a pull rod, pull rod front end are connected with a head thus, draw
Rod rear end is connected with rotational handle, and pull rod is equipped with screw thread, it is characterised in that：On pull rod between silk head and rotational handle
It is set with top pressure sleeve successively, plain thrust bearing, compresses silk braid, wherein：Compression silk braid is by screw thread spinning on pull rod.
Above-mentioned technical proposal is further limited, the top pressure sleeve is the cylinder of one end open, one end equipped with centre bore
Body, towards the front end of pull rod, pull rod passes through the open at one end of top pressure sleeve from centre bore, and spring, spring are equipped in top pressure sleeve
One end by the baffle limiting that is located at outside pull rod on the diameter of axle, the other end of spring withstands on the inner face of top pressure sleeve blind end
On.
Above-mentioned technical proposal is further limited, the rotational handle is fixedly connected by jackscrew with pull rod.
Above-mentioned technical proposal is further limited, the circumferential direction of top pressure sleeve openings one end is evenly arranged with three
A support claw.
Advantageous effect：
Pin removal provided by the present invention, it is mechanism reasonable design, easy to implement, it is small not take up space, be suitable for automobile die,
The industries such as welding fixture, tooling cubing.
It is mounted between top pressure sleeve and silk braid using plain thrust bearing, top pressure sleeve when can prevent twisting from compressing silk braid
It is rotated together with silk braid is compressed, frictional force between top pressure sleeve and silk braid when reducing rotation, operation is light, laborsaving, improves production
Efficiency；
Spring is set in top pressure sleeve, is connected by spring and pull rod support, can prevent top pressure sleeve from shifting, falling off；
Be equipped with plain thrust bearing, top pressure sleeve made to be fixed on pull rod according to pull rod rotation pressure, at the same limit pull rod with
The length that silk head stretches out, facilitates silk head to be torqued into straight pin；
Rotational handle is fixed by jackscrew and pull rod, fixation maintenance easy to disassemble simultaneously；
The circumferential direction of top pressure sleeve openings one end is uniformly arranged there are three support claw, can be carried out on irregular operating mode face
Operation, use scope are wider.
Description of the drawings
Fig. 1 is the decomposition diagram of the present invention.
Fig. 2 is the sectional view of the present invention.
As shown in the figure：1, silk head；2, top pressure sleeve；3, spring；4, plain thrust bearing；5, silk braid is compressed；6, pull rod；7、
Jackscrew；8, rotational handle；9, baffle；10, support claw.
Specific implementation mode
The present invention is as depicted in figs. 1 and 2：
A kind of pin removal, including a threaded pull rod 6,6 front end of pull rod are connected through a screw thread with silk head 1, before the silk head 1
The screw thread for being equipped with and pulling out straight pin cooperation in advance, the rear end of silk head 1 is held to be equipped with internal thread hole, pull rod 6 passes through internal thread hole and silk head 1
Connection, silk head 1 can be replaced according to the different model of straight pin, but silk head 1 and the connecting pin of pull rod 6 remain unchanged, pull rod 6
Rear end is connected with rotational handle 8, and rotational handle 8 is fixed by jackscrew 7 and pull rod 6, on the outer diameter of axle of the pull rod 6, is located at silk
It has been sequentially arranged top pressure sleeve 2 between first 1 and rotational handle 8, plain thrust bearing 4, has compressed silk braid 5, has compressed 5 spinning of silk braid and exists
On the screw thread of pull rod.
The top pressure sleeve 2 is the cylinder of one end open, one end equipped with centre bore, and top pressure sleeve 2 open at one end direction is drawn
The front end of bar 6, pull rod 6 are passed through from centre bore, and spring 3, one end of spring 3 are equipped with inside top pressure sleeve 2, along the 6 outer diameter of axle of pull rod
It is limited by the baffle 9 being located on the 6 outer diameter of axle of pull rod, the other end of spring 3 is resisted against top pressure sleeve 2 with centre bore one end
Inner face, top pressure sleeve 2 and pull rod 6 are clearance fit.
The compression silk braid 5 is the cylinder for being axially arranged with central through hole, and the external screw thread phase with pull rod 6 is equipped in central through hole
The internal thread of cooperation compresses silk braid 5 and is flexibly connected by screw thread between pull rod 6, compresses silk braid 5 and is set as close to 6 rear end of pull rod
Outer-hexagonal shape forms force part, can be rotated with hand, it is also possible to which open-end wrench rotates.
Between the plain thrust bearing 4 is located at top pressure sleeve 2 and compresses silk braid 5, compresses silk braid 5 and pass through plane thrust axis
4 transmission pressure are held to top pressure sleeve 2, while can prevent top pressure sleeve 2 from being rotated with silk braid 5 is compressed, reduce top pressure sleeve 2 and pressure
Frictional force between tight silk braid 5.
The circumferential direction of 2 open at one end of top pressure sleeve is uniformly arranged there are three support claw 10, can be directed to irregular
It is operated on operating surface, use scope is wider.
The operation principle of the present invention：
In use, the silk head 1 mating with straight pin internal thread is tightened mounted on 6 front end of pull rod, it, will be whole by rotating handle 8
A pin removal silk head 1 is torqued into the pre- straight pin threaded hole pulled out, is turned round until torsion is motionless；By three of 2 open end of top pressure sleeve
Support claw is bonded with straight pin installation workpiece, then moves the outer-hexagonal compressed on silk braid 5 with open-end wrench, by twisting silk braid 5,
Pull rod 6 slowly rises with silk braid rotation, after straight pin extracts certain position, pulls 6 upper end handle 8 of pull rod, straight pin is pulled out
Go out.
