Work can be completed by pinching the centre of the palm thumb pin pressing hydraulic hammer force application handle of exerting oneself of drawing pin hydraulic hammer that hand.
The technical solution adopted by the present invention to solve the technical problems is：A kind of drawing pin hydraulic hammer is manufactured, there are one cylindricalitys
Hammer body into shape, hammer body section can be square, positive all directions shape or cylinder, and there is no limit hammer body has concrete shape along cylindrical body
One stairstepping endoporus (defines direction, it is assumed that hammered into shape in vertical in right side, drawing pin hydraulic hammer in fixed face for sake of convenience
Left side in fixed face, hammer Shenzhu body right vertical are the working faces of drawing pin hydraulic hammer nail drawing pin, and left side is hammer body tail
Portion.) by hammer body working face middle position it is small axle diameter cylindrical bore to the left, continuation is large-diameter cylindrical bore, rank to the left
It is equipped with inside trapezoidal endoporus and forms the cylindrical dynamic tup of a ladder circle by two different diameters of axle, move the big small axle diameter point of tup
Fit dimension processing is not moved referred to as using being slidably matched with the size endoporus of hammer body, and is forward moved and matched with the stairstepping endoporus of hammer body
Installation is closed, moves the small axle diameter of tup inside the small axle diameter endoporus of hammer body endoporus, moves the large-diameter of tup in the big of hammer body endoporus
Inside diameter of axle endoporus, the entirety that dynamic tup is made of big small axle diameter can be left inside the big small axle diameter endoporus of hammer body endoporus
It moves right.There are cylindroid helical-coil compression spring abbreviation compression spring, the spiral cylinder internal diameter of compression spring to be more than dynamic hammer between dynamic tup and hammer body
Head small axle diameter, is sleeved on above dynamic tup small axle diameter, and the spiral cylinder outer diameter of compression spring is less than dynamic tup large-diameter part, again smaller than hammer
The large-diameter endoporus of body endoporus, compression spring, which may be mounted at, is but blocked in hammer body small axle diameter endoporus inside hammer body large-diameter endoporus
Left side, compression spring left side are that the large-diameter of tup can bear the thrust of compression spring application, are the small axis for hammering body endoporus into shape on the right side of compression spring
Diameter endoporus limitation compression spring moves to the right, and entire compression spring is limited in the cylindrical dynamic tup of ladder and ladder cylindrical hammer body endoporus shape
At space in.The small axle diameter right hand top circle of reference magnetic plate outer diameter of dynamic tup is provided with endoporus using stationary fit size, uses
Stationary fit mode inlays a round magnetic force steel disc, abbreviation magnetic sheet.Magnetic sheet is fixed on structure on the right side of dynamic tup after stationary fit installation
At dynamic tup working face, dynamic tup will not be spontaneously decoupled.Magnetic sheet can also use other techniques welding either bonding or other
Unknown method is fixed on dynamic tup right hand top, then need not just open endoporus on the right side of dynamic tup.(it should be noted that using
Welding method may make magnetic sheet heating demagnetization, and safe welding type, control welding process magnetic sheet heating degree to be selected not to make
Its demagnetization is too many.If magnetic sheet is fixed on using bonding way above dynamic tup, it should be noted that the type and bonding of bonding glue
Technique cannot come unglued easily.) the cylindrical cross-section product of magnetic sheet is approximately equal to the area of drawing pin cap, magnetic sheet can adsorb drawing pin dynamic
Namely hammer body working face middle position on tup working face into shape.
There are one handle, handles to be installed together by joint pin and hammer body for drawing pin hydraulic hammer.The connection of handle and hammer body
Scheme is there are three types of than more typical mode, the first hammers body ear into shape there are two sides above hammer body tail portion, each hammer into shape respectively has on body ear
One aperture uses the hammer body hole of stationary fit dimensioned with joint pin outer diameter, and handle tip is a handle ear, there is one above
With joint pin outer diameter using the handle hole for moving fit dimension processing, the spacing hammered into shape between two hammer body ears of body can accommodate in a aperture
Move place is hammered between body ear at two and had to handle ear clip into shape, and axis overlaps between two hammer body holes and three hole of handle hole,
Three hole handles are sequentially passed through by joint pin and are mounted on face with hammer, and joint pin may be used common cylinder direct selling and belong to industry
Standard component.Handle is mounted on hammer body tail portion by joint pin.It hammers body hole into shape to process with joint pin outer diameter stationary fit, ensures joint pin peace
Cannot be rotated in hammer body hole will not be spontaneously decoupled hammer body hole, and handle hole and the dynamic cooperation processing of joint pin outer diameter install it
Back handle can be with flexible rotating, without being spontaneously decoupled hammer body under the clamping of two side hammer body ears along joint pin diameter of axle direction.
Second, hammer body hammers above body ear that only there are one with joint pin outer diameter take stationary fit ruler into shape only there are one body ear is hammered into shape
The hammer body hole of very little processing, is also a handle ear above handle, and there are one take dynamic cooperation with joint pin outer diameter above handle ear
The handle hole of dimensioned, there are one the handle taper holes of chamfering structure backwards to hammer body mounting ear side for handle hole, and joint pin, which uses, to be had
The handle taper hole dimension angle of the cone chain pin of taper tail, the taper tail and handle hole of boring chain pin is symmetrical, when installation cone chain pin head part from
Handle hole handle taper hole side penetrates handle hole, and then stationary fit is mounted in hammer body hole again, and cone chain pin taper tail rests on handle
In the handle taper hole of hole, it is stationary fit to bore between chain pin and hammer body hole, and after installation, cone chain pin cannot rotation will not in hammer body hole
It is spontaneously decoupled hammer body hole, although handle hole is cooperation with cone chain pin, still, bore handle taper hole of the taper tail gear in handle of chain pin
Interior, limitation handle can only can not but be spontaneously decoupled cone chain pin on cone chain pin along cone chain pin diameter of axle rotation, that is, handle without
Method is spontaneously decoupled hammer body.Cone chain pin is tapped along cone chain pin axis direction, the handle elastic journey installed above in hammer body can be adjusted
Degree, suitably firmly tapping cone chain pin by cone chain pin taper Caudad hammer body direction can make handle face with hammer be mounted so as to tight one
A bit, suitably firmly tapping cone chain pin from cone chain pin head part to handle orientations can make handle face with hammer be mounted so as to pine.
The third, joint pin can also use standard component split pin to substitute, and it can also be monaural that hammer body ear, which can be ears,
Handle ear equally can be that ears can also be monaural, hammer body hole into shape like that, handle hole can use dynamic match to split pin outer diameter
It closes, part processing is simple, but the split pin opening portion course of work may be suspended to hand either clothing or hanger, need handle
Split pin tail portion disk is at two small circle rings, or abuts against the outside bending of hammer body ear or handle ear and wipe out redundance.Make
For hand-held small tool, unnecessary split pin part end to end, the side of being not preferred have been had more in mounting ear both sides using split pin
Case.
The stage casing of handle is eccentric block, and the distance of eccentric block working face to handle hole central point becomes larger, referred to as
While with path, by major diameter, two parts while with path form eccentric block major diameter, want round and smooth excessive between two parts.Handle is vertical
When hammering body into shape, eccentric block major diameter side is pressed on the left of dynamic tup on large-diameter end face, at this point, right end of the dynamic tup in entire stroke,
Magnetic sheet right side keeps the position concordant with working face on the right side of hammer body.Certainly, magnetic sheet can also be depressed in hammer body working face slightly,
But the depth of this recess is only limitted to the thickness of a drawing pin cap, otherwise drawing pin can be followed closely on fixed face and not leaned on.At certain angle
Handle is lifted in degree together with eccentric block, withstands on the eccentric block on the left of dynamic tup by major diameter when sliding into path, and dynamic tup is being pressed
Can be to movement on the left of hammer body endoporus under spring effect, under handle eccentric block path margin system, dynamic tup will not be fully removed hammer body
Endoporus.It moves tup at this time to be retracted inside hammer body endoporus together with magnetic sheet, the space removed on the right side of hammer body endoporus is equal to drawing pin
Height plus 2~3 millimeters of gap.Handle determines that major diameter arrives handle hole central point half while with path relative to the angle of hammer body rotation
The ratio of diameter.The ratio of design is big, and handle is small relative to the angle of hammer body rotation when work, and when work is applied to the power above handle
It is big with regard to needing；The ratio of contradictory design is small, and handle just needs greatly relative to the angle of hammer body rotation when work, and when work is applied to hand
Power above handle is with regard to small.It is recommended that handle relative to hammer body rotation angle between 15 °~30 °, the excessive centre of the palm of angle is pressed downwards
Inconvenient when pressure, angle is less than normal, ensure again dynamic moving hammer distance caused by eccentric block rotation add 2 more than drawing pin total height~
3 millimeters of gap, the ratio between radius of major diameter while to the radius and path of handle hole to handle hole will be designed very
Greatly, may be painstaking using the drawing pin hydraulic hammer course of work, or even press completely motionless.
Handle eccentric block major diameter side tail portion there are one stay hook, hammer body and stay hook corresponding position install a lock hook with
Stay hook, which is hooked together, limits handle rotation at one piece.The installation in lock hook face with hammer is equally there are three types of mode it can be selected that the
One kind, there are two lock hook mounting ear, abbreviation latch ears for the hammer body tail portion opposites Chui Shener corresponding position.It is respectively provided with above latch ear
One axis overlaps the lock hole in aperture and locking pin stationary fit processing, and there are one apertures and locking in lock hook hook body centre position
The lock hook mounting hole abbreviation hook body hole of the dynamic cooperation processing of pin is overlapped with locking axially bored line, and locking pin passes through two lock holes and folder
Lock hook is mounted on hammer body in the following, lock in intermediate hook body hole and the torque spring abbreviation torsional spring heart hole of limitation lock hook torsion
Industrial standard straight pin may be used in rationed marketing.It hammers body lock hole into shape to process using stationary fit with locking pin, locking pin exists after installation
Cannot be rotated in lock hole will not be spontaneously decoupled lock hole.Torsional spring heart hole is more than locking pin outer diameter, and hook body hole is adopted with locking pin
It is processed with dynamic cooperation, it is interior that the spacing between two latch ears allows lock hook and torsional spring to be easily mounted on, and lock hook and torsional spring are logical
It, can be within a certain angle along locking pin diameter of axle flexible rotating without voluntarily after locking pin is crossed in hammer body lock hole
It is detached from locking pin, lock hook cannot be detached from hammer body.
Second scheme, hammer body only there are one latch ear, above latch ear only there are one with locking pin stationary fit processing
Lock hole, lock hook hook body there are one and the dynamic cooperation processing of locking pin hook body hole, hook body hole is backwards to there are one the latch ear sides
More than the chamfering structure taper uropore abbreviation gouge hole in hook body hole, locking pin has one using the cone rationed marketing for having taper tail, cone rationed marketing
It is a with the symmetrical taper tail in gouge hole, cone rationed marketing head penetrates hook body hole from lock hook gouge hole side when installation, then wears again
Cross torsional spring heart hole, finally again be mounted on hammer body lock hole in, cone rationed marketing taper tail rest in lock hook gouge hole, cone rationed marketing with
It is stationary fit between hammer body lock hole, after installation, cone rationed marketing cannot rotate in lock hole will not be spontaneously decoupled hammer body lock
Determine hole, although lock hook hook body hole is cooperation with cone rationed marketing, still, the taper tail for boring rationed marketing is kept off in lock hook gouge hole,
Limitation lock hook can only can not but be spontaneously decoupled cone rationed marketing on cone rationed marketing along cone rationed marketing diameter of axle rotation, and lock hook can not be voluntarily
It is detached from hammer body.Cone rationed marketing is tapped along cone rationed marketing axis direction, lock hook and torsional spring can be adjusted in installed above elastic of hammer body
Degree, suitably firmly tapping cone rationed marketing by cone rationed marketing taper Caudad hammer body direction can make lock hook and torsional spring in hammer body lock hole
Inside it is mounted so as to tighter, suitably firmly tapping cone rationed marketing from cone rationed marketing head to lock hook direction can be such that lock hook and torsional spring installs
It obtains more loose.
The third, locking pin can also use split pin to substitute, and latch ear lock hole can be that monaural single hole can also be
Ears diplopore, lock hook hook body hole can be that monaural single hole can also be ears diplopore, and lock hole, hook body hole can use dynamic
Cooperation, as previously mentioned, correlated parts processing is simple, still, the equally possible extension hand of the split pin opening portion course of work or clothing
Object or hanger are needed split pin tail portion disk into two small circle rings, or simultaneously against bending on the outside of latch ear or hook body ear
Wipe out redundance.As hand-held small tool, unnecessary split pin head-tail has been had more in hammer body both sides using split pin
Point, it is that alternative is but not preferred scheme.
The processing and installation of link structure and above-mentioned handle and hammer body between lock hook mentioned herein and hammer body
The processing of link structure can also be there are many Scheme Choice, for example, hammer body mounting ear uses monaural, handle and lock hook with installation
Using ears；Or the hole in piece part mounted on mounting pin middle section uses stationary fit with mounting pin, is mounted on mounting pin both sides
Partial hole in piece part is with mounting pin using dynamic cooperation；Or mounting pin use has ladder stern construction.This all various combination, no
It can say that any is preferred plan, can be liked according to factory's technology, equipment, process conditions level and designer and be determined.As
Hand-held small tool is flexible and convenient to use to want with good appearance, does not outline one by one herein.
In handle depressing position, lock hook is combined under the action of torsional spring with the stay hook hook below eccentric block, is limited
Handle processed twists.There are one unlocking buttons for lock hook tail portion, press unlocking button, and lock hook turns to a certain point of view,
Stay hook is released, and is pulled handle and is rotated clockwise certain angle together with eccentric block, is pressed in the eccentric block on the left of dynamic tup by big
For diameter when being slid onto path, dynamic tup can also be moved to the left a trip under compression spring effect, and (this stroke should be more than one
The total height of drawing pin adds 2~3 millimeters of gap) hammer body endoporus right end vacated one accommodate and add 2 more than or equal to a drawing pin
The space in~3 millimeters of gap.Cage knob is discharged at this time, and lock hook is still maintained at original latched position in the case where hammer body abuts against.
One drawing pin is adsorbed on dynamic tup magnetic sheet, when drawing pin is attracted to inside hammer body endoporus, drawing pin recess completely is hidden in hammer
Inside body endoporus, drawing pin point distance hammer body surface still have one section about two to three millimeters of distance, it is ensured that drawing pin hydraulic hammer edge
When suspended matter product surface is slided, drawing pin point will not be suspended to suspended matter, and hand-held drawing pin hydraulic hammer presses against or hold up suspended matter
It is moved to along fixed face and needs position, the centre of the palm firmly presses force application handle, and handle reverses certain angle counterclockwise, drives eccentric block
Compressing pushes dynamic tup to move to the right and drawing pin is pressed into fixed face.In this process, compressing lock hook in stay hook inclined-plane is oblique
