Abstract
The utility model provides a drill chuck. The drill chuck comprises a drill body, a nut and a clamping jaw. The nut is installed on the drill body in a rotating mode and is positioned in the axial direction, and the clamping jaw is in threaded connection with the nut. Threads for the threaded connection of the nut and the clamping jaw are multiple threads. According to the drill chuck, when the nut is rotated to drive the clamping jaw to clamp a tool, the tool can be quickly clamped, and operating time is shortened.
Description
Technical field
The utility model relates to a kind of drill chuck.
Background technology
Drill chuck such as hand fastening drill clutch, comprises drill body, nut, jaw, and described nut is rotatably installed on the drill body and is positioned in the axial direction, and described jaw is connected with nut thread.The nut of existing drill chuck and jaw threaded engagement adopt the one start screw transmission, reliable transmission, but need a lot of circles of rotation to live tool holding, waste time and energy.
Summary of the invention
Technical problem to be solved in the utility model provides the drill chuck of the quick clamping tool of a kind of energy.For this reason, the utility model by the following technical solutions: it comprises drill body, nut, jaw, and described nut is rotatably installed on the drill body and is positioned in the axial direction, and described jaw is connected with nut thread; The screw thread that is threaded with jaw on the described nut is multiple thread.
On the basis of adopting technique scheme, the utility model also can adopt following further technical scheme:
The screw thread that is threaded with jaw on the described nut is the 2-4 head thread.
When described screw thread was 2 head threads, its lead angle was 2.06 °-2.10 °.
When described screw thread was 3 head threads, its lead angle was 3.09 °-3.15 °.
When described screw thread was 4 head threads, its lead angle was 4.10 °-4.20 °.
The screw thread that is threaded with jaw on the described nut is the 5-8 head thread.
Be distributed with the jaw hole of inclination around its axis in the described drill body, described jaw is provided with external screw thread and is connected with the described nut thread of nut, and described jaw penetrates the jaw hole and by described nut thread driving and move along described jaw hole.
Owing to adopt the technical solution of the utility model, when the utility model drove the jaw clamping tool at the rotation nut, clamping tool reduced the operating time very rapidly.

The specific embodiment
Embodiment 1, with reference to accompanying drawing 1-6.
The utility model comprises drill body 1, nut 6, jaw 7, and described nut 6 is rotatably installed on the drill body and is positioned in the axial direction, and described jaw 7 is connected with nut thread; The screw thread 61 that is threaded with jaw on the described nut 6 is multiple thread.
Nut can be by realizing axial location and rotatable in the nut groove that is installed in the drill body middle part, perhaps nut is axially located by the step surface on the drill body and the front and back cooperation that is in the procephalic drill chuck part of drill point and is rotatable; Perhaps nut is connected with following rotary sleeve one and is axially located and rotatable, and the axial location of nut and rotation also can be adopted other multiple structure, and these structures are by disclosed prior aries such as patent documentations.
Present embodiment is example with the hand fastening drill clutch, be distributed with the jaw hole 71 of inclination in the described drill body 1 around its axis, described jaw 7 is provided with external screw thread and is connected with the described nut thread 61 of nut 6, and described jaw 7 penetrates jaw hole 71 and driven and moved along described jaw hole by described nut thread 61.Drawing reference numeral 3 is the rotary sleeve that is connected with nut.Drawing reference numeral 4,5 is respectively packing ring and the bearing between nut and the drill chuck, and drawing reference numeral 2 is the bonnet of drill chuck.
In force, the screw thread that is threaded with jaw on the described nut is generally the 2-4 head thread; Guaranteeing that under the constant substantially situation of chucking power, clamping tool reduces the operating time very fast.When described screw thread was 2 head threads, its lead angle was 2.06 °-2.10 °, and present embodiment is 2.08 °; When described screw thread was 3 head threads, its lead angle was 3.09 °-3.15 °, and present embodiment is 3.11 °; When described screw thread was 4 head threads, its lead angle was 4.10 °-4.20 °, and present embodiment is 4.14 °.
The screw thread 61 that is threaded with jaw on the described nut 6 also can be the 5-8 head thread, or the screw thread of bull more, although this moment, lead angle was big, the self-lock force of screw thread reduces more, but clamp speeds can be quicker, can be applicable to some special occasions, and, by improving material or adopting other fit structure, also can improve the problem that self-lock force reduces, make it have wider purposes.
Drawing reference numeral L is the girth of nut.
Embodiment 2, with reference to accompanying drawing 3-8.
Present embodiment is example with the spanner drill chuck, and it comprises drill body 101, nut 106, jaw 107, and described nut 106 is rotatably installed on the drill body and is positioned in the axial direction, and described jaw 107 is connected with nut thread; The screw thread 161 that is threaded with jaw on the described nut 106 is multiple thread.
Drawing reference numeral 162 is the bevel ring gear of nut front end, and drawing reference numeral 111 is the spanner locating hole on the drill body.Drawing reference numeral 103 is the shell of drill chuck, and drawing reference numeral 171 is the jaw hole on the drill body.
The screw thread 161 of present embodiment is identical with the nut thread of embodiment 1.
