Description
Technical field
This utility model relates to hand fastening drill clutch.
Background technology
Hand fastening drill clutch is the one in conventional drill chuck, and it directly uses hands rotation drill chuck rotary sleeve to carry out unscrewing or tightening operation.Traditional hand fastening drill clutch, between the drill body support level at nut and its rear, packing ring is set, packing ring is that interference fit is fixed on drill body, install and requirement on machining accuracy is higher, both needed from circumference orientation adaptive with jaw, need again the magnitude of interference moderate, it is to avoid after needing bigger assembly force between packing ring and drill body and using, sliding to occur.And nut is arranged in the nut draw-in groove in the middle part of drill body, in order to assemble, need first to cut away half nut, use nut sleeve that it is fit after installing in drill body nut draw-in groove again, manufacture and assembly process is relative complex.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of easily manufactured, hand fastening drill clutch of registration.To this end, this utility model is by the following technical solutions:
Hand fastening drill clutch, including drill body, nut, jaw, the middle part of described drill body arranges support level, support level is placed packing ring, it is characterised in that described packing ring is that the structure coordinated by keyway is positioned on drill body.
Using on the basis of technique scheme, this utility model also can use technical scheme or be combined using further below to these technical schemes:
Described groove is the breach formed by laterally punching to drill body.
Described drill body has positioning step in the front portion of support level, and the week of positioning step, described positioning step protruded from the drill body part in its front, and the groove that described keyway coordinates is formed on positioning step in the face of packing ring radially location.
The slot to make way of jaw it is provided with on described packing ring.
Being not provided with nut stopper slot on described drill body, the rotary sleeve of described nut and drill chuck connects；The axial limiting of described nut does not use described nut stopper slot, but by the most limited described rotary sleeve by axial limiting, or by axial limiting together with described rotary sleeve；The rear end of described nut is supported on described packing ring or by bearings on packing ring, and the front end of described drill body arranges the front end limiting component of rotary sleeve.
Described rotary sleeve and nut are integral type.
Described rotary sleeve and nut embedding and injection molding link together.
Described nut and rotary sleeve have keyway fit structure simultaneously.
Described rotary sleeve and nut interference fit connect, and nut outer peripheral face and rotary sleeve inner peripheral surface have keyway fit structure at interference fit position simultaneously.
Described nut is inserted in described rotary sleeve, and nut outer peripheral face and rotary sleeve inner peripheral surface keyway coordinate, described rotary sleeve from the front portion of nut to its axial limiting.
Owing to using the technical solution of the utility model, this utility model simple in construction, easily manufactured, by keyway space washer, without considering further that interference problem, both facilitated the installation of packing ring, and ensured again the stable performance of life-time service, and described packing ring can be made automatically to make its jaw slot to make way adaptation jaw in the circumferential after keyway coordinates location.And, this utility model is from nut, the consideration axial limiting generally of rotary sleeve, both the installation of nut, packing ring had been further facilitated, a part of axial limit structure of drill chuck can be saved again, it is the most fit that nut is no longer necessary to first be cut into two halves, the overall assembly process of drill chuck simplifies, and is beneficial to reduce cost.

Detailed description of the invention
Referring to the drawings.Hand fastening drill clutch provided by the utility model includes drill body 1, nut 3, jaw 4, drill chuck rotary sleeve 2, and described rotary sleeve 2 is limited in the axial direction of drill chuck.The middle part of described drill body arranges support level 11, and support level 11 is placed packing ring 6, and described packing ring 6 is that the structure coordinated by keyway is positioned on drill body 1.Described key 61 can be set on packing ring 6, described drill body 1 has positioning step 12 in the front portion of support level 11, the week of positioning step 12 is in the face of packing ring 6 radially location, described positioning step 12 protrudes from the drill body part 13 in its front, the groove 14 that described keyway coordinates is formed on positioning step 12, described key refers to the structure that can play location fit effect of projection, and described groove refers to the depressed area preset with key location fit.Can also be that groove is arranged on packing ring, key be arranged on drill body.
Described groove 14 is the breach formed by laterally punching 15 to drill body 1.
The slot to make way 62 of jaw it is provided with on described packing ring 6.
It is not provided with nut stopper slot on described drill body 1, described nut 3 and described rotary sleeve 2 connect, this connection can be to be connected as one by embedding and injection molding, described nut 3 and rotary sleeve 2 also can have keyway fit structure simultaneously, or, being connected to one by modes such as interference fit, nut outer peripheral face and rotary sleeve inner peripheral surface can have keyway fit structure at interference fit position simultaneously, and drawing reference numeral 31 is the keyway realizing keyway cooperation on nut.So, rotary sleeve 2 is limited in the axial direction of drill chuck, then nut 3 is the most limited.
Or, position limiting structure is simultaneously to rotary sleeve 2 axial limiting together with nut 3.
Placing pad 6 and bearing 5 on described support level 11, the rear end of described nut 3 is supported on packing ring 6 by stating bearing 5, and the front end of described drill body arranges the front end limiting component 7 of rotary sleeve.
Described rotary sleeve can be from the front portion of nut to its axial limiting, and drawing reference numeral 20 is the rotary sleeve 2 spacing position from the front portion of nut 3 to its axial limiting.
Described nut 3 and described rotary sleeve 2 are not necessarily intended to fixing connection, described nut is inserted in described rotary sleeve, the keyway formed simply by the keyway on nut outer peripheral face and rotary sleeve inner peripheral surface coordinates and connects as one, described rotary sleeve from the front portion of nut to its axial limiting.
In the present embodiment, nut need not first cut away half fit by nut sleeve the most again, and can be directly set to together with rotary sleeve on drill body by whole nut, assembles very convenient.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited thereto, any those skilled in the art is in the field of the invention, and change or the modification made all are contained among protection domain of the present utility model.
