Technical field
The utility model belongs to plated film field, metallic surface, the coating clamp of the clamping jaw when relating in particular to a kind of jaw plated film that is applied in the drill chuck.
Background technology
At present, drill chuck is metal machining tool and the power tool accessory of using always, and its structure mainly comprises jaw, clamper main body and nut sleeve three parts.The drill bit, cutter or the part that put in Yu contract out and clamp or loosen clamping of jaw mainly leaned in the work of drill chuck.Jaw produces mechanical friction in repeatedly clamping, the working process of unclamping; When the abrasion loss of jaw workplace surpasses certain numerical value; The clamping force of jaw and precision all can obviously descend, and drill chuck will occur because of the not enough drill slipping of clamping force, and precise decreasing causes the drill bit swing; Problems such as centering is inaccurate, deterioration in quality.So improve the work-ing life that the wear resisting property of jaw directly improves drill chuck.For this reason, people utilize the surface deposition rete of physical gas phase deposition technology (PVD) at jaw, improve the wear resisting property of jaw; Make chuck can improve the strength of clamping automatically; Thereby increase exponentially torsion,, guarantee product precision and quality to prevent the drill slipping of clamping.The structural representation of jaw, shown in Fig. 1 a and 1b, jaw is a right cylinder, and the pinching end 101 that its main workplace is an inclined-plane, the other end are the end of engagement 103 with flank of tooth, and all the other are non-main workplace 102.Main workplace pinching end 101 needs coating, the processing requirement even film layer with non-main workplace 102; The power and the end of engagement 103 of the flank of tooth can not be reduced friction is so can not there be coating.
The utility model content
The purpose of the utility model is to propose a kind of coating clamp that is applicable to the jaw in the drill chuck.
The purpose of the utility model will be achieved through following technical scheme:
A kind of jaw coating clamp comprises a rotating shaft, is arranged with a spacer with said rotating shaft rotation in the said rotating shaft; Be fixedly connected with on the said spacer one with the concentric discoidal jig main body of said rotating shaft; Said jig main body is made up of an elastic wire a plurality of supporter that coiling forms that joins end to end, and it is radial that said each supporter is isogonism around said rotating shaft; Said each supporter includes and is used for the tail end that is connected with adjacent supporter and has the interior receptacle portion of circular accommodation space; Said tail end is near said rotating shaft, and the axis normal of said tail end is in the rotation of said rotating shaft; Receptacle portion is away from said rotating shaft in said, and the parallel axes of said interior receptacle portion is in the rotation of said rotating shaft; The outline of the interior profile of said interior receptacle portion and jaw to be coated is complementary, and said jaw is folded in the said interior receptacle portion.
Preferably; Above-mentioned a kind of jaw coating clamp; Wherein: said spacer is made up of two interconnective concentric outer toroid and interior annulus; Said spacer is concentric with said rotating shaft, mills on the outer toroid of said spacer and has positioning groove in vain, and said jig main body is through said tail end and said positioning groove clamping.
Preferably, above-mentioned a kind of jaw coating clamp, wherein: said jaw is a right cylinder, and an end of said jaw is the pinching end on an inclined-plane, and the other end is the end of engagement of a flank of tooth.
Preferably; Above-mentioned a kind of jaw coating clamp; Wherein: the end of engagement of said jaw is coated with the anchor clamps that cover that match with the flank of tooth of said end of engagement, and the said jaw that covers anchor clamps that is coated with is folded in the said interior receptacle portion, thereby has guaranteed that the flank of tooth does not have coating.
A kind of jaw coating clamp of the utility model can guarantee that the coating of jaw requires and performance requriements; The rete color and luster is even, and plated film requires consistent, and anchor clamps adopt the good spring wire of elastic performance to process simultaneously; Production cost is low; Installation way is simple, can easily pack jaw into easily and unload, and lean on the elasticity of material self to guarantee that jaw can not drop easily in coating process; Can significantly improve the loading production capacity of jaw in the plated film production process, reduce manual work, the production capacity problem when having satisfied volume production.The utility model has designed and has covered anchor clamps also according to the self-characteristic of jaw, has guaranteed that the flank of tooth does not have coating.
Following constipation closes the embodiment accompanying drawing, the embodiment of the utility model is done further to detail, so that the utility model technical scheme is easier to understand, grasp.
