Abstract
Disclosed is a center capable of processing a center hole and used for carbon and graphite materials. The center comprises a cylindrical portion and a conical portion connected with the cylindrical portion. The center is characterized in that a cutting blade (2) is arranged on the conical portion (3) along the direction of a taper angle and has no relief angle, and the taper angle of the conical portion (3) is 60 degrees. The center can serve as a cutting tool to process the center hole and also can serve as a center to support a processed workpiece, so that accuracy of the position of the center hole is guaranteed while troubles in replacement of the cutting tool and the center are avoided. By the center, secondary positioning errors when the center hole is processed can be avoided, and operation simplifying can be realized.
Description
Technical field
The present invention relates to process the cutlery of the usefulness of center hole, can process the top of center hole especially for charcoal element and graphite material.
Background technology
The part that has (for example clavate part) is adding man-hour, need to make centre bore in the end in advance, with this centre bore as the positioning datum that adds later on man-hour.In charcoal element and graphite material processing, when processing existing center hole, also must be at the end face centering of work piece.Its step is to unload first toply from top tailstock, and den bohrkopf einsetzen is given the work piece centering; And then from the top tailstock den bohrkopf abbauen, load onto toply, withstand work piece, on this basis processing.The shortcoming of this mode is to have the secondary orientation problem, makes centre bore and top concentricity produce error; And operate cumbersomely, need during the course to change top, drill bit, operation is many, and the time is long.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can process the top of center hole for charcoal element and graphite material, solving the deficiency of above-mentioned technology, the present invention can be as the cutlery of centering, simultaneously also as the top use of supporting workpiece, avoid the secondary position error, simplify manually-operated.
Technical scheme of the present invention is: the present invention can process the top of center hole for what be used for charcoal element and graphite material, described top have column part and the tapered segment that is connected with column part, it is characterized in that: on described tapered segment, have a cutting edge along the cone angle direction, described cutting edge is without relief angle.
Described top coning angle can be 60 degree.
The present invention is top for processing, support charcoal element and graphite material workpiece.Both as boring cutlery, again as supporting the top of usefulness.The present invention is top to be with top without the relief angle cutting edge, on same station, can get centre bore as cutlery, can support processed workpiece as top again.Guaranteed central hole location accurately, saved again and changed cutlery, top trouble.During use, during work in-process heart hole, use as cutlery, this moment, workpiece rotating did not toply rotate, but to workpiece direction straight-line feed, cutting edge on the tapered segment plays cutting, in order to get centre bore, because cutting edge is not with relief angle, the part of all the other cone Surface Contact workpiece plays grinding.When supporting top uses, this moment top feed-disabling, top can be with workpiece rotating, top under the effect of frictional force with the workpiece synchronous rotary, this moment, top the cutting and abrasive action only played supporting workpiece.
In sum, the top cost of manufacture of the present invention is low, uses simple.Secondary position error when the present invention can avoid centering, and simplify the operation.
Description of drawings
Fig. 1 is the top stereogram of the present invention.
Fig. 2 is the top front view of the present invention.
Fig. 3 is the A-A cutaway view among Fig. 2.
Code name among the figure:
1 column part, 2 cutting edges, 3 tapered segments
The specific embodiment
As shown in Figure 1, 2, 3, the present invention can process the top of center hole for charcoal element and graphite material, the described top tapered segment 3 that has column part 1 and be connected with column part 1, the angle that described top coning angle is pressed general center hole is taken as 60 degree.On described tapered segment 3, have a cutting edge 2 along the cone angle direction, described cutting edge 2 is without relief angle.
During use, this is top to can be used for similar centre bore at materials such as lathe processing charcoal element, graphite, then plays a supportive role.Top afterbody can be processed into the form that is fit to installation according to the tail stock form.This top machined material that utilizes is softer charcoal element, the characteristics of graphite, when boring, workpiece rotating and toply do not rotate, use top feeding, this moment, cutting edge contacted workpiece simultaneously with taper seat, under the effect of centripetal force, at first to the workpiece cutting, taper seat grinds the finished surface of cutting edge cutting edge subsequently simultaneously.After boring, during as top supporting workpiece, workpiece rotating, top can the rotation, but top feed-disabling, this moment, cutting edge 2 lost centripetal force, and cutting edge 2 stops the workpiece cutting, and top taper seat is under the effect of frictional force, with the workpiece synchronous rotary.On same station, finish the work of centering and support with same instrument, guarantee centre bore accurately, reduced the operating time.
Claims (2)
1. what be used for charcoal element and graphite material can process the top of center hole, described top have column part and the tapered segment that is connected with column part, it is characterized in that: on described tapered segment (3), have a cutting edge (2) along the cone angle direction, described cutting edge (2) is without relief angle.
2. according to claim 1 top, it is characterized in that: the coning angle of described tapered segment (3) is 60 degree.
