Abstract
The utility model provides a new chuck, comprising a chuck body, a chuck thread and a clamping jaw; wherein, a bevel gear is arranged on the back end face of the chuck thread; a tooling hole is positioned at the chuck body corresponding to the arc bevel gear at the back end face of the chuck thread. Due to adopting the technical proposal, the utility model has the advantages of higher connection strength, more reliable performance of the chuck, higher clamping force, and longer service life after the chuck thread fitted with corresponding tools.
Description
Technical field
The utility model relates to a kind of chuck.
Background technology
In the prior art, chuck comprises disk body, the claw of chuck, is provided with parcel in the disk body, and the front end face of parcel is threaded with claw, and the rear end face of parcel is provided with screw thread.During operation, utilize the instrument with parcel rear end face threaded engagement, rotate parcel, make the claw motion that is threaded with parcel to clamp or to loosen workpiece.At present, the rear end face screw thread of parcel is the umbrella shape straight-tooth, and the instrument intensity that is threaded with it 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 new-type chuck.For this reason, the utility model by the following technical solutions: it comprises disk body, parcel, claw, and the rear end face of parcel is provided with the umbrella tooth, and described disk body is provided with tooling hole with respect to the rear end face umbrella tooth place of parcel, and the umbrella tooth of described parcel rear end face is an arc umbrella tooth.Owing to adopt the technical solution of the utility model, parcel can obtain higher bonding strength with after corresponding tool cooperates, and makes the performance of chuck more reliable, and higher clamping force of acquisition and longer service life.
The utility model also can adopt following further technical scheme simultaneously:
The instrument that cooperates with the rear end face umbrella tooth of parcel is installed in the described tooling hole, and described instrument is a bevel gear, and described bevel gear axially is positioned at it, and the tooth of described bevel gear is the arc umbrella tooth that cooperates with parcel rear end face arc umbrella tooth.
