Abstract
The utility model relates to a force arm type disassembling tool which is used for disassembling components and parts in automobile and machine repair. The utility model is composed of supporting plates, a force arm lever, pawls and pawl sleeves. Both sides of the horizontal central line of each supporting plate are provided with symmetrical strip-shaped slide ways. The force arm lever is provided with fulcrum holes corresponding to the strip-shaped slide ways, and the force arm lever is movably connected between the corresponding strip-shaped slide ways of two supporting plates by fulcrum pins. Two end corners of each supporting plate is provided with the rotatable pawl sleeves, and the inner part of each pawl sleeve is provided with a telescopic pawl. The force arm type disassembling tool has simple structure, convenient carrying and easy use, and is an ideal tool for automobile repair work.
Description
The utility model relates to a kind of special tool of dismantling the flush fit part.
In the maintenance of automotive wheels wheel or mechanical bearing, servicing operations, often need these friction tight parts are disassembled.At present, adopt the pusher withdrawing device of screw rod comparatively general, this special tool mainly is the rotation mode that utilizes screw rod, and dog plate and screw rod that silk is combined on the screw rod produce phase shift, thereby pull down the parts that unloaded.Though the pusher withdrawing device of screw rod has advantage, the subject matter that exists is: the time of the required usefulness of dismounting parts is longer; Because the parts that unloaded are often diversified in specifications, need be equipped with the dog plate of many specifications.Therefore, carry and use all not too convenient.
The purpose of this utility model provides a kind of arm of force formula withdrawing device, and it can adapt to the different size that is unloaded parts, can promptly dismantle parts.
For achieving the above object, the utility model has adopted a kind of arm of force formula withdrawing device, all have the strip slideway of symmetry on two identical shaped back plate horizontal surface center line both sides, and become splayed to distribute, on the cooresponding strip slideway symmetrical arm bar is being arranged between two back plates, have one and the corresponding fulcrum hole of strip slideway on this arm bar, and flexibly connect with fulcrum pin.The catch jacket of rotation is housed between the arc tips angle of two back plate symmetries, telescopic claw is housed in this catch jacket.
The advantage of arm of force formula withdrawing device of the present utility model is: simple in structure, easy manufacturing, and carry and use very convenient.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the half-sectional view of facing of the utility model arm of force formula withdrawing device.
Fig. 2 is the birds-eye view of the utility model arm of force formula withdrawing device.
By Fig. 1,2 as can be known, arm of force formula withdrawing device of the present utility model is made up of two identical shaped back plates (1), arm bar (3), catch jacket (6) and claw (8), all have the strip slideway (2) of symmetry on the both sides of two back plates (1) horizontal central line, and become splayed to distribute.The shape and the duckbilled of arm bar (3) are close, have on the duckbilled push rod plane one with the corresponding fulcrum hole of strip slideway (2) (4), along arm bar (3) Yi Bian the tangential direction of the garden arc end wall that arches upward to the binding site on duckbilled top combine harmoniously for toe-in always.Arm bar (3) is placed between two back plates (1), fulcrum hole (4) is alignd with cooresponding strip slideway (2), flexibly connect with fulcrum pin.Also have the fixed orifice (10) and the knock hole (9) of symmetry on two back plates (1) horizontal central line both sides, knock hole (9) is opened on the end angle of two garden arc shapes on back plate (1) forward end limit.The coupling link (5) that casting is connected in catch jacket (6) bottom is contained between the cooresponding knock hole (9), and fixed orifice (10) and knock hole (9) all use the set pin of coupling and locating dowel pin to flexibly connect.Catching cover (6) is horizontally rotating between two back plates (1) up and down by knock hole (9) is fixing with locating dowel pin.Catch jacket (6) and claw (8) have cooresponding one and arrange claw hole (7) longitudinally, and flexibly connect by the claw pin.
Embodiment:
When the utility model used, the quilt that claw is blocked interference fit unloaded the edge of parts, and claw can be adjusted according to the distance of being unloaded parts, the arm bar top withstands on another parts, fold two arm bars under the effect of external force, at this moment, fulcrum pin drive armed lever is along the slippage of strip slideway.Along with slipping, the straight line end wall of two arm bars can in conjunction with, and use arm bar top not easily separated.The power of the top direction of arm bar acts on the summit all the time like this, is unloaded parts thereby can pull down fast.
Claims (3)
1, a kind of arm of force formula withdrawing device, it comprises back plate, arm bar, claw and catch jacket, it is characterized in that: two identical back plates (1) horizontal central line both sides all have the strip slideway (2) of symmetry, and become splayed to distribute; The arm bar (3) that symmetry is arranged on cooresponding strip slideway (2) between two back plates (1), it is corresponding with strip slideway (2) to have a fulcrum hole (4) on the arm bar (3), and flexibly connects with fulcrum pin (5); Between the arc tips angle of two back plates (1) symmetry, rotating catch jacket (6) is housed, telescopic claw (8) is arranged in this catch jacket (6).
2, by the described arm of force formula of claim 1 withdrawing device, it is characterized in that: the shape and the duckbilled of arm bar (3) are close, along arm bar (3) Yi Bian the tangential direction of the garden shape end wall that arches upward to the binding site on duckbilled top combine harmoniously for toe-in always.
3, by the described arm of force formula of claim 1 withdrawing device, it is characterized in that: have on catch jacket (6) and the claw (8) arranging claw hole (7) longitudinally, this claw hole (7) locks with the claw pin of coupling is movable.
