Abstract
A method for processing taper shank drill into straight shank drill comprises a process for cutting a taper shank of a taper shank drill by the cutting tool of a lathe, wherein the process comprises the following steps: fixedly connecting a steel cylinder with a chuck of the lathe spindle, drilling a taper pit on the end face of the steel cylinder by a core drill in such a manner that the central axis of the taper pit is superposed with the central axis of the lathe spindle, arranging the taper shank drill to be processed between the taper pit and the top tip of the lathe tail seat, applying an axial force to the taper shank drill by the top tip of the lathe tail seat, and cutting the taper shank drill by the cutting tool while rotating the lathe spindle. By using the steel cylinder as the fixture and by using the taper pit to fix the cutting blade of the taper shank drill, the method can firmly fix the taper shank drill, thus solving the technical problem of prior art that the taper shank drill is difficult to be fixed while cutting.
Description
Technical field:
The present invention relates to mechanical field, relate in particular to metal cutting technology, particularly a kind of method that taper shank drill is processed into straight shank drill.
Background technology:
Processing work on drilling machine and vertical knee-type milling machine often need be used straight shank drill, but does not have suitable straight shank drill at present.In the prior art, change system into straight shank drill by the taper-shank drill that size is suitable and solve this problem.But the taper shank of taper-shank drill and spiral cutting edge cylindrical make it be difficult to clamping when cutting.
Summary of the invention:
The purpose of this invention is to provide and a kind of taper shank drill is processed into the method for straight shank drill, the described this method that taper shank drill is processed into straight shank drill is difficult to the technical problem of clamping in the time of will solving cutting taper-shank drill in the prior art.
This method that taper shank drill is processed into straight shank drill of the present invention comprises the process of the taper shank of a lathe tool cutting taper-shank drill that utilizes lathe, wherein, in the process of the taper shank of the described lathe tool cutting taper-shank drill that utilizes lathe, a fixedly connected steel cylinder on the chuck of lathe spindle at first, in the cylindrical end face of steel, utilize center bit to get out a taper nest then, the central axis of described taper nest and the central axes of lathe spindle, again with taper-shank drill device to be processed between the tailstock centre of taper nest and lathe, utilize the tailstock centre of lathe to apply axial force to described taper-shank drill, last boring-and-turning mill main shaft utilizes lathe tool that taper-shank drill is cut simultaneously.
Further, the degree of depth of described taper nest is between 4～8 millimeters.
Operation principle of the present invention is: the present invention utilizes the steel cylinder as anchor clamps, utilizes the fixedly cutting edge of taper-shank drill of taper nest, firmly the clamping taper-shank drill.
The present invention and prior art contrast, and its effect is actively with tangible.The present invention utilizes the steel cylinder as anchor clamps, utilizes the fixedly cutting edge of taper-shank drill of taper nest, and firmly the clamping taper-shank drill has solved the technical problem that is difficult to clamping when cutting taper-shank drill in the prior art.
Description of drawings:
Fig. 1 is the schematic diagram of an embodiment of the method that taper shank drill is processed into straight shank drill of the present invention.
The specific embodiment:
As shown in Figure 1, in one embodiment of the invention, the method that taper shank drill is processed into straight shank drill comprises the process of the taper shank of lathe tool 1 a cutting taper-shank drill 2 that utilizes lathe, wherein, in the process of the taper shank of the described lathe tool that utilizes lathe 1 cutting taper-shank drill 2, a fixedly connected steel cylinder 4 on the chuck 3 of lathe spindle at first, in the end face of steel cylinder 4, utilize center bit to get out a taper nest then, the central axis of described taper nest and the central axes of lathe spindle, again taper-shank drill to be processed 2 is installed between the tailstock centre 5 of taper nest and lathe, utilize the tailstock centre 5 of lathe to apply axial force to described taper-shank drill 2, last boring-and-turning mill main shaft utilizes 1 pair of taper-shank drill 2 of lathe tool to cut simultaneously.
Further, the degree of depth of described taper nest is between 4～8 millimeters.
The course of work of present embodiment is: the present invention utilizes steel cylinder 4 as anchor clamps, utilizes the fixedly cutting edge of taper-shank drill 2 of taper nest, firmly clamping taper-shank drill 2.
Claims (2)
