Abstract
The utility model discloses a guide sleeve of a deep-hole gun drill, and relates to the technical field of numerical control machine tool machining. In order to solve the problems of damage and scrapping of a workpiece during machining and leakage of cutting oil between the workpiece and a guide sleeve, the utility model provides the guide sleeve of the deep-hole gun drill, wherein the guide sleeve is sleeved on the end surface of the workpiece; the guide sleeve comprises a guide sleeve body and an O-shaped rubber sealing ring; an annular groove is formed in the end face, connected with the workpiece, of the guide sleeve body, and the annular groove is inverted cone-shaped; the O-shaped rubber sealing ring is positioned in the annular groove. The utility model provides a guide sleeve of a deep-hole gun drill, which has the advantages that an O-shaped rubber sealing ring is additionally arranged on the front end surface of the guide sleeve, so that the sealing and buffering effects are realized between a workpiece and the guide sleeve, and the problems of workpiece damage and sealing are effectively solved.
Description
Technical Field
The utility model relates to the technical field of numerical control machine tool machining, in particular to a guide sleeve of a deep-hole gun drill.
Background
When the gun drill is used for drilling, the gun drill is not provided with guide and the drill point of the gun drill deviates from the axial lead of the drill bit, so the gun drill is easy to deviate when cutting into a workpiece. Thus, a guide bushing must be used to guide the gun drill in order to obtain precise positioning while cutting into the workpiece. Therefore, the end face of the guide sleeve is tightly attached to the end face of the machined hole of the workpiece during drilling, and the gun drill is guided to drill with high precision.
The hardness of a guide sleeve used on a machine tool is usually higher than HRC60, the guide sleeve is tightly attached to the end face of a workpiece, the end face of the workpiece is extruded and damaged, and the workpiece is scrapped particularly when nonferrous metals or parts with high requirements on the end face roughness are machined. And the sealing between the workpiece and the guide sleeve is unreliable, so that the condition of leakage of cutting oil is often generated, and the normal machining of a machine tool is influenced.
In view of the above, there is a need to design a guide sleeve for a deep-hole gun drill that overcomes the above-mentioned technical problems.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to overcome the defects in the prior art, and provide a guide sleeve of a deep-hole gun drill, wherein an O-shaped rubber sealing ring is additionally arranged on the front end surface of the guide sleeve, so that the sealing and buffering effects are realized between a workpiece and the guide sleeve, and the problems of workpiece damage and sealing are effectively solved.
In order to achieve the above purpose, the present invention mainly provides the following technical solutions:
the guide sleeve of the deep hole gun drill is sleeved on the end surface of a workpiece; the guide sleeve comprises a guide sleeve body and an O-shaped rubber sealing ring; an annular groove is formed in the end face, connected with the workpiece, of the guide sleeve body, and the annular groove is inverted cone-shaped; the O-shaped rubber sealing ring is positioned in the annular groove.
Compared with the prior art, the utility model has the following beneficial effects:
according to the guide sleeve of the deep-hole gun drill, the O-shaped rubber sealing ring is additionally arranged on the end face of the guide sleeve body, so that the sealing and buffering effects are achieved between a workpiece and the guide sleeve, and the problems of workpiece damage and sealing are effectively solved.
According to the guide sleeve of the deep-hole gun drill, the annular groove in the end face of the guide sleeve is in the inverted cone shape, so that the O-shaped rubber sealing ring can be effectively prevented from falling off.
The foregoing is a summary of the present invention, and in order to provide a clear understanding of the technical means of the present invention and to enable the same to be carried into effect in accordance with the present specification, the following detailed description of the preferred embodiments of the present invention is provided in conjunction with the accompanying drawings.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.
FIG. 1 is a schematic structural view of a guide sleeve of a deep-hole gun drill according to the present invention;
FIG. 2 is an enlarged schematic view of the present invention at the annular groove;
description of reference numerals:
1. a guide sleeve body;
2. an O-shaped rubber sealing ring;
3. an annular groove.
Detailed Description
To further illustrate the technical means and effects of the present invention for achieving the intended purpose of the present invention, the following detailed description will be given to specific embodiments, structures, features and effects of a deep-hole gun drill guide sleeve according to the present invention with reference to the accompanying drawings and preferred embodiments.
As shown in fig. 1-2, the guide sleeve is sleeved on the end face of the workpiece; the guide sleeve comprises a guide sleeve body 1 and an O-shaped rubber sealing ring 2; an annular groove 3 is formed in the end face, connected with the workpiece, of the guide sleeve body 1, and the annular groove 3 is inverted conical; the O-shaped rubber sealing ring 2 is positioned in the annular groove 3.
According to the guide sleeve of the deep-hole gun drill, when a workpiece needs to be machined, the O-shaped rubber sealing ring 2 is firstly placed in the inverted-cone-shaped annular groove 3 of the guide sleeve body 1, and then the workpiece is attached to the end face of the guide sleeve; in the process of clinging, the workpiece firstly contacts the O-shaped rubber sealing ring 2, and the O-shaped rubber sealing ring 2 is extruded to be combined with the end face of the guide sleeve. The O-shaped rubber sealing ring 2 plays a role in sealing and buffering between the workpiece and the guide sleeve, and effectively meets the requirements of part collision damage and processing sealing.
The present invention has been further described with reference to the examples, but the present invention is not limited to the above-described embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
