Abstract
The invention provides a step deep hole bore cutter, and particularly relates to a cutter. The cutter comprises a handle, wherein a sleeve sleeves the handle; the sleeve is fixedly connected with the handle; the lower end surface of the sleeve is a tool face; a thread hole is formed in the middle part of the handle; a screw rod is arranged in the thread hole; the tool face is arranged at the front end of the screw rod; a sandwich layer is arranged in the sleeve; the sandwich layer is a threaded hole; bolts are formed in the threaded hole. The cutter has the advantages of being simple in structure, reasonable in design, simple in operation, practical and convenient, and high in precision; after the common drilling work is finished, the cutter is not pulled out, the bolts are rotated, the bolts are screwed on the step surface of a step hole, and the screw rod is rotated for drilling the deep hole again.
Description
Technical field:
The present invention relates to a kind of step deep hole bore cutter, be specifically related to a kind of cutter.
Background technology:
When boring shoulder hole, generally all use subland drill, this drill bit structure is fixed, and the hole wall ratio of the shoulder hole of brill is fixed, and when needing to carry out intensification work to deep hole, needs by another honor head, and recalibrate, precision has impact.
Summary of the invention:
Technical problem to be solved by this invention is the defect overcoming prior art, provides a kind of step deep hole bore cutter.
Technical problem to be solved by this invention realizes by the following technical solutions.
A kind of step deep hole bore cutter, it is characterized in that: comprise handle of a knife, handle of a knife cover has sleeve pipe, and sleeve pipe is fixedly connected with handle of a knife, and described its lower end face is knife face, screwed hole is provided with in the middle of described handle of a knife, be provided with screw rod in screwed hole, screw front end is provided with knife face, is provided with interlayer in described sleeve pipe, interlayer is screwed hole, is provided with screw in interlayer.
Described sleeve surface is cascaded surface.
Described interlayer is provided with three places altogether, and is evenly distributed on sleeve pipe.
Beneficial effect of the present invention is: structure is simple, reasonable in design, after common boring end-of-job, without the need to extracting cutter, rotating screw, withstands on screw on shoulder hole cascaded surface, makes its lower end knife face unsettled, rotating screw bolt, carry out drilling deep hole again, simple to operate, practical and convenient, precision is high.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Detailed description of the invention:
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
A kind of step deep hole bore cutter as shown in Figure 1, comprise handle of a knife 1, handle of a knife cover has sleeve pipe 2, and sleeve pipe is fixedly connected with handle of a knife, and its lower end face is wherein knife face, screwed hole 3 is provided with in the middle of described handle of a knife, be provided with screw rod 4 in screwed hole, screw front end is provided with knife face, is provided with interlayer 5 in sleeve pipe wherein, interlayer is screwed hole, is provided with screw 6 in interlayer.
Sleeve surface is wherein cascaded surface.
Interlayer is wherein provided with three places altogether, and is evenly distributed on sleeve pipe.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
