Description
Technical field
The present invention relates to the hand-held tool field, especially hand-held clip erector.
Background technology
The automobile fuel injector utilizes U type clip as shown in Figure 1 12 to realize the locking and the sealing at pipe joint place, in the process of using, prevents the phenomenon of the interface generation high-pressure leakage of fuel injector and oil pipe.Because clip need utilize elasticity to realize chucking, so initial tension is very tight usually, manual work is manual installs very difficulty, and efficient is very low.And because clip is less, as easy as rolling off a log ejection is landed during installation, is infected with dust.On the one hand, can cause the fuel injector product percent of pass to descend, on the other hand, the dust particles on the clip is mingled in the fuel oil, and the fuel injector clogging takes place, and influences the serviceability of fuel injector.
Summary of the invention
The applicant is difficult to shortcomings such as installation to the clip of above-mentioned existing automobile fuel injector, hand-held clip erector a kind of rational in infrastructure, easy to operate is provided, thereby can realizes the installation of U type clip easily.
The technical scheme that the present invention adopted is following:
A kind of hand-held clip erector, the clip cylindrical shell with formed the cavity that holds clip after the clip plug cooperates, clip plug length is slightly less than the height of clip cylindrical shell; The bottom of clip cylindrical shell is fixed with base, and base matches with the fuel injector shape; The top of clip cylindrical shell utilizes two lugs of pivotal axis and pressing plate to articulate, and the installed inside of pressing plate has stop nut and spring, and quadrature is equipped with the top tongue in the outer end of pressing plate, and the thickness of top tongue is suitable with the thickness of clip, and it is interior and push clip to be inserted into square hole during work.
Further improvement as technique scheme: the inner hole section shape approximation of said clip cylindrical shell is in the clip profile, and sectional dimension is slightly larger than the peripheral dimension of clip; The shaft section shape approximation of clip plug is in the clip profile, and sectional dimension is slightly less than interior all sizes of clip.
Said base is the semi open model structure, makes corresponding to fuel injector top structure shape and stepping down.
Beneficial effect of the present invention is following:
The present invention uses the principle that is similar to stapler, clip is installed on the clip plug at first in batches, and advances in the clip cylindrical shell, through pressing plate and top tongue clip is pushed up on the fuel injector then, thus the Fast Installation of realization fuel injector front band; Utilized lever principle, fast and safely laborsaving.The present invention is disposable can to install the clip about 30 in batches, improves the efficient that the fuel injector clip is installed effectively; Also avoid simultaneously clip to eject the quality problems that fall on the ground and cause, fully guaranteed the installation quality of clip.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
Like Fig. 2, shown in Figure 3, hand-held clip erector agent structure of the present invention is matched with clip plug 4 by clip cylindrical shell 3 and forms, and the inner hole section shape approximation of clip cylindrical shell 3 is in clip 12 profiles, and sectional dimension is slightly larger than the peripheral dimension of clip 12; The shaft section shape approximation of clip plug 4 is in clip 12 profiles; And sectional dimension is slightly less than interior all sizes of clip 12; Clip cylindrical shell 3 with formed the cavity that holds clip 12 after clip plug 4 cooperates; And clip 12 relies on the gravity stacked arrangement in this spatial accommodation and be free to slide with the chamber wall and cooperate, and can fall one by one during work to put in place.Clip cylindrical shell 3 highly is about 70mm, can hold about 30 clips like this.Clip core cap 5 is installed through screw 6 in clip plug 4 tops, and clip plug 4 length are about 68mm, can be ejected smoothly with the clip 12 that guarantees to be installed in the clip cylindrical shell 3, is unlikely to be stuck.Clip core cap 5 is convenient to grip on the one hand, can realize the spacing of extreme position during work, has certain gravity simultaneously, promotes clip 12 blanking one by one during work.
The bottom of clip cylindrical shell 3 is fixed on the base 1 through screw 2, and is as shown in Figure 5, and base 1 is the structure of semi open model, makes corresponding to fuel injector electromagnet cylinder and peripheral structure shape and steps down and cooperate.Base 1 and clip cylindrical shell 3 form a square hole 13 between the cylindrical shell rear side, referring to Fig. 4, match with top tongue 11.The center-hole diameter of base 1 is than the big 0.5mm effect of fuel injector electromagnet body diameter, and this tolerance fit handled easily personnel on the one hand can be inserted into base 1 on the fuel injector electromagnet cylinder exactly, guarantees to install later stability simultaneously again.One side of base 1 is removed the bit space of reserving behind the part material that lets, and considers that the angle between automatically controlled magnetic valve joint and the fuel injector electromagnet cylinder can change along with the fuel injector model, thereby has reserved the space to automatically controlled magnetic valve joint.The first half of base 1 is provided with the catch of 2～3mm, plays positioning action through contacting with fuel injector electromagnet cylinder upper surface.
Clip cylindrical shell 3 tops as shown in Figure 6 utilize rivet to articulate as two lugs of pivotal axis 7 with pressing plate 8; The installed inside of pressing plate 8 has stop nut 9 and spring 10; Quadrature is equipped with top tongue 11 in the outer end of pressing plate 8; The thickness of the thickness of top tongue 11 and clip 12 is suitable, is inserted in the square hole 13 during work and pushes clip 12.
During real work, operating personnel are installed on the clip plug 4 clip 12 and stacked arrangement earlier one by one, and the clip plug 4 that will have clip 12 then advances in the clip cylindrical shell 3.Hand-held the present invention utilizes base 1 to be positioned on the fuel injector electromagnet cylinder, pushes pressing plate 8 with palm then, and top tongue 11 is pushed out clip cylindrical shell 3 with clip 12, and installs and be secured on the fuel injector, and it is spacing that utilize stop nut 9 to carry out this moment.Under the gravity effect, the clip on top 12 continues to fall to putting in place and prepares pushing next time, and spring 10 rebounds it after top tongue 11 is pressed onto the end and resets simultaneously.The present invention is convenient to operation, is similar to " stapler " action, can realize the installation of clip 12 apace, and the situation that clip 12 ejections are dropped can not take place.
More than describing is to explanation of the present invention; It or not qualification to invention; Institute of the present invention restricted portion is referring to claim, and under the situation of spirit of the present invention, the present invention can do any type of modification; For example change the shape of cylindrical shell and plug, form the suitable cavity that holds according to difform clip.
