Abstract
The utility model provides a spanner drill chuck, which comprises a drill body, a chuck jaw, and an axially positioned structural member forming a screw-thread connection with the chuck jaw, wherein the front end of the structural member is provided with a ring gear. The utility model is also provided with a spanner wheel meshed with the ring gear. An installation structure of the spanner wheel is arranged at the front end of the drill body, and the spanner wheel is provided with an operating hole matching with a tool. The shape of the operating hole can be made into a shape matching with a common tool by the utility model, for example, the operating hole can be made into a groove in a plum-blossom shape. As a result, the spanner wheel can be wrenched by a conventional tool and the rotation of the spanner can be used for driving the structural member to rotate around the drill body. Therefore, the drilling tool can be clamped more firmly, so that the commonality and the convenience of the drill chuck can be improved.
Description
Technical field
The utility model relates to a kind of drill chuck, relates in particular to a kind of for example spanner drill chuck on drilling machine, the electric drill of machining equipment and electric tool that is installed in.
Background technology
In the prior art, spanner drill chuck generally is made up of drill body, overcoat, nut, jaw and auxiliary member spanner.Three jaws are separately positioned on and are distributed on the drill body in three inclined holes interference fit between nut and the overcoat.The front end of overcoat is provided with gear ring, and the front end of drill body is provided with the driving hole of restriction spanner position.Nut is as the structural member that is threaded with jaw, jaw passes in and out in inclined hole to clamp drilling tool thereby the operation overcoat drives nut rotation drive, spanner is inserted in the drill body driving hole again, firmly rotation, the gear ring engagement fit of the tooth of spanner and overcoat front end, thereby drive overcoat around the drill body rotation, clamp drilling tool more securely.Present spanner drill chuck, its spanner are special-purpose auxiliaries, in case lose or can not find for the moment, just can't operate drill chuck.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of spanner drill chuck that overcomes above-mentioned defective.For this reason, the utility model is by the following technical solutions: it comprises drill body, jaw, and the structural member that axially is positioned, be threaded with jaw, the front end of described structural member is provided with gear ring, it also is provided with the wheel of pulling with described gear ring engagement, be provided with the mounting structure of pulling wheel at the drill body front end, pull wheel and have the handle hole that cooperates with instrument.Owing to adopt technique scheme, make handle hole can make the shape that cooperates with general tool, such as the groove of making the plum blossom shape.Like this, can pull wheel, and drive structural member around the drill body rotation, clamp drilling tool more securely, thereby improved the versatility and the convenience of drill chuck by the rotation of pulling wheel by the instrument of routine.
The described mounting structure of pulling wheel can comprise the sleeve shape body that is connected with drill body, has on the described sleeve shape body to pull the wheel hole, pulls to take turns to be arranged in and pulls the wheel hole.Sleeve shape body can encase the front end and the front end gear ring of drill chuck; structure tool to the protection drill chuck is very helpful, and sleeve shape body also can carry out axial limiting to the structural member that is threaded with jaw; make structural member can adopt whole screw element, thereby can improve the precision of drill chuck.
Description of drawings
Fig. 1 partly cuts open schematic diagram for the utility model embodiment's.
Fig. 2 be Figure 1A to projection view.
Fig. 3 is the figure that blows of the utility model embodiment.
The specific embodiment
With reference to accompanying drawing.The utility model comprises drill body 1, jaw 4, and the structural member that axially is positioned, be threaded with jaw, the front end of described structural member is provided with gear ring 21, it also is provided with pulling of described gear ring engagement and takes turns 5, be provided with the mounting structure of pulling wheel at the drill body front end, pull wheel and have the handle hole 53 that cooperates with instrument.Drawing reference numeral 51 for the gear teeth of pulling of gear ring 21 engagements.The shape of described handle hole can be made as shown in Figure 2, is the plum blossom flute profile, like this, just can handle as common instruments such as screwdrivers and to pull wheel.
Described structural member is meant the torsion of accepting input and rotates, and passes through part or the part combination that threaded engagement drives the jaw motion.
In the present embodiment, described structural member that axially be positioned, that be threaded with jaw is the overcoat 2 that is provided with jaw threaded engagement face.As shown in Figure 1, the front inner wall of overcoat 2 is made into the shape that cooperates with the jaw that tilts, and the internal thread 22 that cooperates with external screw thread on the jaw in this surface setting, and gear ring 21 is located at the front end of overcoat 2.Certainly, with regard to enforcement, also the aforementioned shape that cooperates with the jaw that tilts partly can be made a monoblock type nut, then this nut is connected with the overcoat interference fit, thereby constitute described structural member.At this moment, gear ring 21 can be located at the front end of overcoat; Certainly, by the change to nut shape, the front end of nut can be given prominence to the front end at overcoat, and therefore gear ring 21 also can be arranged on the front end of nut.
The described mounting structure of pulling wheel comprises the sleeve shape body 3 that is connected with drill body, has on the described sleeve shape body to pull wheel hole 32, pulls to take turns to be arranged in and pulls the wheel hole.The tail end of pulling wheel is provided with boss 52, and drill body front end side is being provided with hole 11 corresponding to the boss place, and boss is stuck in the hole of drill body front end side by the wall of sleeve shape body.Certainly, also can take turns the hole and pull the corresponding location structure that is shaped between the wheel pulling of sleeve shape body, wheel be pulled in the location in this way.
The rear end face of sleeve shape body is provided with the groove 31 that cooperates with gear ring.Described sleeve shape body externally cover is axially spacing.Drawing reference numeral 12 is for being molded over the boss on the drill body, and it carries out axial limiting to structural member from the rear.
