Abstract
The utility model provides a valve seat milling holes frock which characterized in that: comprises a base; a circular groove is formed in the geometric center of the top surface of the base, and the diameter of the periphery of the groove is larger than that of the periphery of the workpiece; a through hole for fastening a workpiece is formed in the geometric center of the bottom surface of the groove; the bottom surface of the groove is provided with four positioning holes for positioning a workpiece, the centers of the four positioning holes are positioned on the same circle taking the center of the bottom surface of the groove as the center of the circle, and the diameter of the circle where the centers of the four positioning holes are positioned is equal to the diameter of the circle determined by the centers of the positioning holes on the workpiece; the device also comprises four positioning pins; the four pressing plates are arranged at four corners of the top surface of the base; the pressing part penetrates through the groove through hole and is used for pressing the workpiece. The space for avoiding the cutter in the hole milling process is provided, the surface of a workpiece can be effectively prevented from being scratched by aluminum scraps generated in hole milling, and meanwhile, the workpiece can be prevented from displacing when the cutter mills the workpiece for the last time.
Description
Technical Field
The utility model relates to a machinery product processing field, in particular to valve seat milling holes frock.
Background
The aluminum valve seat is a common part in the aerospace field and mainly plays a role in connection and support. When an aluminum workpiece is machined, even if a machine tool is used and a new tool is used, deformation is easy to occur after machining, and the precision is difficult to control. When the door seat is used for milling holes, aluminum scraps generated by cutting a workpiece by a cutter are easy to scratch the surface of the workpiece. Therefore, the design of a scientific, reasonable and efficient clamping tool is necessary for accurately processing the milling hole of the aluminum valve seat.
Disclosure of Invention
In view of this, the utility model provides a revolving door seat milling holes frock.
The utility model aims at realizing through the following technical scheme:
a milling hole tool for a valve seat comprises a base; a circular groove is formed in the geometric center of the top surface of the base, and the diameter of the periphery of the groove is larger than that of the periphery of the workpiece; a through hole for fastening a workpiece is formed in the geometric center of the bottom surface of the groove; the bottom surface of the groove is provided with four positioning holes for positioning a workpiece, the centers of the four positioning holes are positioned on the same circle taking the center of the bottom surface of the groove as the center of the circle, and the diameter of the circle where the centers of the four positioning holes are positioned is equal to the diameter of the circle determined by the centers of the positioning holes on the workpiece; the device also comprises four positioning pins; the four pressing plates are arranged at four corners of the top surface of the base; the pressing part penetrates through the groove through hole and is used for pressing the workpiece.
Further, the through hole of the groove is an internal thread hole.
Further, the pressing portion is a bolt, and the bolt can be matched with the internal thread hole.
Further, the peripheral diameter of the groove is larger than the sum of two times of the peripheral diameter of the used tool and the diameter of the periphery of the workpiece.
The utility model has the advantages that:
the utility model discloses utilize circular recess as the place the platform of work piece, provide the space that the cutter was dodged to the hole milling in-process, can effectively prevent the aluminium bits fish tail workpiece surface that the hole milling produced, can prevent simultaneously that the cutter from taking place the displacement when the work piece is milled at last time.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the means of the instrumentalities and/or combinations particularly pointed out in the appended claims.
Drawings
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings, in which:
FIG. 1 is a schematic structural view of the present invention;
Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for purposes of illustration only and are not intended to limit the scope of the present invention.
Fig. 1 is a schematic structural view of the present invention, and a valve seat milling tool includes a base 1; a circular groove 2 is arranged at the geometric center of the top surface of the base 1, and the diameter of the periphery of the groove 2 is larger than that of the periphery of the workpiece 6; a through hole for fastening a workpiece 6 is arranged at the geometric center of the bottom surface of the groove 2; the bottom surface of the groove 2 is provided with four positioning holes for positioning the workpiece 6, the centers of the four positioning holes are positioned on the same circle taking the center of the bottom surface of the groove 2 as the center of the circle, and the diameter of the circle where the centers of the four positioning holes are positioned is equal to the diameter of the circle determined by the center of the positioning hole on the workpiece 6; also comprises four positioning pins 3; the device also comprises four pressing plates 4 arranged at four corners of the top surface of the base 1; and a pressing part which penetrates through a through hole of the groove 2 and is used for pressing the workpiece 6.
Further, the through hole of the groove 2 is an internal thread hole.
Further, the compressing part is a bolt 5, and the bolt 5 can be matched with the internal thread hole.
Further, the peripheral diameter of the recess 2 is larger than the sum of twice the peripheral diameter of the tool used and the peripheral diameter of the workpiece 6.
When the press-fitting device works, the base 1 is pressed on the workbench by the four press plates 4. The four pressing plates are placed at four corners of the top surface of the base, and bolts penetrate through the pressing plates 4 to fix the base 1.
Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the scope of the claims of the present invention.
