Technical field
The invention belongs to plated film field, metal surface, the coating clamp of the clamping jaw when relating in particular to a kind of jaw plated film that is applied in drill chuck.
Background technology
At present, drill chuck is metal machining tool and the electric tool accessory of commonly using, and its structure mainly comprises jaw, clamper main body and nut sleeve three parts.The work of drill chuck is putting in and the drill bit, cutter or the part that contract out and clamp or loosen clamping by jaw mainly.Jaw produces mechanical friction in repeatedly clamping, the course of work of unclamping, when the wear extent of jaw working face surpasses certain numerical value, the clamping force of jaw and precision all can obviously descend, drill chuck will appear because of the inadequate drill slipping of clamping force, precise decreasing causes that drill bit swings, the problems such as centering is inaccurate, deterioration in quality.So improve the service life that the anti-wear performance of jaw directly improves drill chuck.For this reason, people utilize physical gas phase deposition technology (PVD) at the surface deposition rete of jaw, improve the anti-wear performance of jaw, make chuck can automatically improve the strength of clamping, thereby increase exponentially torsion, to prevent the drill slipping of clamping, guarantee Product Precision and quality.The structural representation of jaw, as shown in Fig. 1 a and 1b, jaw is cylinder, and the pinching end 101 that its main working face is an inclined-plane, the other end are the end of engagement 103 with flank of tooth, and all the other are non-main working face 102.Main working face pinching end 101 and non-main working face 102 need coating, the technological requirement even film layer; 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.
Summary of the invention
The objective of the invention is to propose a kind of coating clamp that is applicable to the jaw in drill chuck.
Purpose of the present invention will be achieved by the following technical programs:
A kind of plating clamp for clamping jaws comprises a rotating shaft, is arranged with a locating rack with described rotating shaft rotation in described rotating shaft; Be fixedly connected with a discoidal jig main body concentric with described rotating shaft on described locating rack; Described jig main body is comprised of an elastic wire a plurality of supporter that coiling forms that joins end to end, and it is radial that described each supporter is isogonism around described rotating shaft; Described each supporter includes for the tail end that is connected with adjacent supporter and has the interior receptacle portion of circular accommodation space; Described tail end is near described rotating shaft, and the axis of described tail end is perpendicular to the rotation of described rotating shaft; Described interior receptacle portion is away from described rotating shaft, and the axis of described interior receptacle portion is parallel to the rotation of described rotating shaft; The outline of the interior profile of described interior receptacle portion and jaw to be coated is complementary, and described jaw is folded in described interior receptacle portion.
Preferably, above-mentioned plating clamp for clamping jaws, wherein: described locating rack is comprised of two interconnective concentric outer toroid and interior annulus, the interior annulus of described locating rack can be set in rotationally with described rotating shaft the outer surface of described rotating shaft, mill on the outer toroid of described locating rack and have positioning groove in vain, described jig main body is by described tail end and described positioning groove clamping.
Preferably, above-mentioned plating clamp for clamping jaws, wherein: described jaw is cylinder, and an end of described 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 plating clamp for clamping jaws, wherein: the end of engagement of described jaw is coated with the fixture that covers that matches with the flank of tooth of described end of engagement, and the described jaw that covers fixture that is coated with is folded in described interior receptacle portion, thereby has guaranteed that the flank of tooth does not have coating.
Plating clamp for clamping jaws of the present invention can guarantee that the coating of jaw requires and performance requirement, the rete color and luster is even, plated film requires consistent, fixture adopts the good spring steel wire of elastic performance to make simultaneously, production cost is low, installation way is simple, can easily pack jaw into easily and unload, and guarantee that by the elasticity of material self 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 present invention has designed and has covered fixture 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 specific embodiment of the present invention is described in further detail, so that technical solution of the present invention is easier to understand, grasp.
