Abstract
The utility model provides a spanner drill chuck, comprising a drill body, a claw, a nut positioned axially and a front end face gear ring. The nut and the claw are screwed connected with each other and the tooth of the front end face gear ring is arc bevel tooth. The utility model also provides a spanner of the spanner drill chuck, comprising a spanner handle and a bevel gear. The tooth of the bevel gear is arc bevel tooth matched with the arc tooth of the spanner drill chuck. The utility model has the advantages that the connection strength between the spanner drill chuck and the spanner is strong, thus enabling to provide a bigger torque force; the spanner drill chuck has more reliable performance and can provide bigger clamping force and longer service life.
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.The utility model also relates to a kind of spanner drill chuck spanner.
Background technology
In the prior art, spanner drill chuck is general main to be made up of drill body, shell, nut, front end face gear ring, 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, 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, again spanner is inserted in the spanner locating hole on the drill body, spanner tooth and front end face gear ring engagement fit, firmly rotation, thereby drive nut around the drill body rotation, clamp drilling tool more securely.Present spanner drill chuck, front end face gear ring are the umbrella shape straight-tooth, and the spanner tooth is the umbrella shape straight-tooth also, and the intensity that is threaded between them still remains further to be improved.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned defective, provides a kind of bonding strength stronger novel spanner drill chuck.For this reason, the utility model by the following technical solutions: it comprises drill body, jaw, and nut that axially is positioned and front end face gear ring, and nut and jaw are threaded, and the tooth of described front end face gear ring is an arc umbrella tooth.Owing to adopt the technical solution of the utility model, the front end face gear ring can obtain higher bonding strength with after corresponding tool cooperates, and makes the performance of spanner drill chuck more reliable, and higher clamping force of acquisition and longer service life.
Another technical problem to be solved of the utility model provides the spanner drill chuck spanner that a kind of and above-mentioned novel spanner drill chuck cooperates, for this reason, the utility model is by the following technical solutions: it comprises trigger piece and bevel gear, and the tooth on the described bevel gear is the arc umbrella tooth that cooperates with the arc umbrella tooth of above-mentioned spanner drill chuck.Because adopt described technical scheme, the spanner that the utility model provides can cooperate with the front end face gear ring of above-mentioned spanner drill chuck, increases the bonding strength between them, imports bigger torsion, make drill chuck obtain higher clamping force.

The specific embodiment
With reference to accompanying drawing 1-4.The utility model comprises drill body 1, jaw 4, and nut 3 that axially is positioned and front end face gear ring 31, and nut and jaw are threaded, and the tooth of described front end face gear ring 31 is an arc umbrella tooth.
In the present embodiment, install for convenience, nut adopts two halves formula structure, be arranged in the nut groove at drill body middle part, by with the shell 2 of nut interference fit with nut combinations together.Drawing reference numeral 12 is the connecting hole that cooperates with driving device in the drill body.Drawing reference numeral 14 is the spanner locating hole on the drill body.
Described front end face gear ring is formed in the front end face of nut.
The spanner that cooperates with the utility model comprises trigger piece 6 and bevel gear 51, and the tooth on the described bevel gear is the arc umbrella tooth that cooperates with the arc umbrella tooth of front end face gear ring 31.Drawing reference numeral 5 is inserted in the spanner positioning head in the spanner locating hole 14.
With reference to accompanying drawing 5-7.Present embodiment is basic identical with embodiment 1, and just shell also has the front end face outside being exposed to simultaneously, and front end face gear ring 21 is formed in the front end face of shell.
In Fig. 5-7, the drawing reference numeral representative identical implication identical with accompanying drawing 1-4.
