Abstract
The utility model belongs to the technical field of the drilling tool clamping device and specifically relates to a hand-held drill chuck, it is including boring body, clamping jaw, bearing pad, screw cover, front cover, back cover, hou gai etc. clamping jaw partial shipment in the inclined hole on boring the body, the screw dress is in the screw groove of boring the body, and the screw cover is established in the outside of screw, and the front portion of screw cover is equipped with the keyway, and the back cover front end is equipped with the key, and the key cooperatees with the keyway, realizes the interlock. The utility model discloses rational in infrastructure, excellent performance, installation convenient to use when the pine presss from both sides the drill bit, can come out the strength full play of hand, reaches the clamp force of ideal, uses on can extensively being used for various electronic, pnematic tools.
Description
The utility model relates to a kind of drilling tool clamping device, specifically a kind of manually fastened drill chuck.
At present, the various manually fastened drill chucks that use on the market, generally be by drill body, jaw, screw, bearing, bearing gasket, nut sleeve, protheca, the back cover is formed, drill body is connected with back cover interference, three jaws are contained in respectively in three inclined holes of drill body, screw is installed in the screw groove of drill body, internal thread is arranged on the screw, and internal thread cooperates with external screw thread on the jaw and forms thread transmission, screw outside suit nut sleeve, the nut sleeve front portion is provided with several keyways, be provided with the key that cooperates with keyway in the protheca, protheca drives nut sleeve by key, and nut sleeve drives screw and rotates, and on the drive jaw, move down, realize the purpose of loose stick of tool head.Said structure, because of structure and spatial constraints, the size of protheca is restricted, and drill chuck must act on simultaneously with two hands when pine is pressed from both sides, thereby when clamping with hand or unclamping, the strength of hand can not be given full play to, and does not often reach desirable clamping force, and overlaps the phenomenon that gets loose before and after in use also can occurring.
The purpose of this utility model is exactly to provide a kind of structure more reasonable, easy to use in order to overcome the deficiency of above-mentioned prior art, the manually fastened drill chuck that the effect of drill chuck is given full play to.
For achieving the above object, a kind of manually fastened drill chuck, comprise drill body, jaw, bearing, bearing gasket, screw, nut sleeve, back cover and protheca, jaw is divided in the inclined hole on the drill body, establish external screw thread on the jaw, screw is contained in the screw groove on the drill body, establish internal thread on the screw, it cooperates with external screw thread on the jaw and forms the screw thread drive mechanism, and nut sleeve is contained in the outside of screw, its front portion is provided with several keyways, the front end inside of back cover is provided with several keys, and it matches with keyway on the nut sleeve, and the back cover rotates, the drive nut sleeve rotates, nut sleeve drives screw and rotates, thereby makes on the jaw, move down, realize the purpose of loose stick of tool head, protheca is positioned at the front end and the drill body interference fit of drill body, transmits moment of torsion.
The utility model also is provided with bonnet, and bonnet is located at the back of back cover, with the drill body interference fit, plays dustproof effect, has increased the overall aesthetics of drill chuck simultaneously again.
The utility model has been owing to adopted said structure, when loose stick of tool head, need not two hands and exerts oneself simultaneously, just the strength of hand can be given full play of, reach desirable clamping force, also avoid in use, the phenomenon that gets loose of front and back cover, function admirable, easy to install.
Below in conjunction with accompanying drawing the utility model is done further detailed description:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model STRUCTURE DECOMPOSITION figure.
Fig. 1, Fig. 2 are the embodiment schematic diagram.
From Fig. 1 and Fig. 2 as can be seen, a kind of manually fastened drill chuck, it comprises protheca 1, back cover 2, nut sleeve 3, screw 4, bearing 5, bearing gasket 6, jaw 7, drill body 8, bonnet 9 etc.Three jaws 7 of the utility model are contained in respectively in 15 ° of inclined holes of three five equilibriums on the drill body 8, and jaw 7 is provided with external screw thread, and screw 4 is contained in the screw groove on the drill body 8, establishes internal thread on the screw 4, and it cooperates with external screw thread on the jaw 7, forms the screw thread drive mechanism.It has bearing 5 and bearing gasket 6, strong nut sleeve 3 is contained in the outside of screw 4 in the rotation of screw 4, and its front portion is provided with several keyways, said structure all is sleeved in protheca 1 and the back cover 2, be provided with several axial keys in the front end of back cover 2, these keys match back cover rotation with keyway on the nut sleeve 3, the drive nut sleeve rotates, nut sleeve drives screw and rotates, and jaw is upper and lower to be moved thereby make, and realizes the purpose of loose stick of tool head.The back of back cover 2 is provided with bonnet 9, and bonnet 9 is contained in the rear portion of drill body 8, with the drill body interference fit, plays dustproof effect, has increased the overall aesthetics of drill chuck simultaneously again.Protheca 1 is smaller, is positioned at the front end of drill body 8, with the drill body interference fit, transmits moment of torsion, protheca 1 also shouldn't, in the time of not, be installed on the main frame, drill chuck still can operate as normal.
Claims (2)
1, a kind of manually fastened drill chuck, comprise drill body, jaw, bearing, bearing gasket, screw, nut sleeve, back cover and protheca, jaw is divided in the inclined hole on the drill body, establish external screw thread on the jaw, screw is contained in the screw groove on the drill body, establish internal thread on the screw, it cooperates with external screw thread on the jaw and forms the screw thread drive mechanism, nut sleeve is contained in the outside of screw, its front portion is provided with several keyways, it is characterized in that being provided with several keys in the back cover front end, and it matches with keyway on the nut sleeve, back cover and nut sleeve interlock, protheca and drill body front end interference fit.
