Abstract

The utility model discloses a machining tool of a part with an arc head on a screw rod end portion. The machining tool of the part with the arc head on the screw rod end portion comprises a tool body, one end of the tool body is in a ring shape, positioning holes which are distributed in parallel along the peripheral direction and are matched with a screw rod of the part are formed in the ring shape part of the tool body, axes of the positioning holes penetrate through the center in an extending mode, a cylindrical surface or a cylinder hole face is arranged at the other end of the tool body, wherein the cylindrical surface or the cylinder hole face is coaxial with an external circle of the ring shape part . When the tool is machined, the part is arranged in the positioning holes, arc faces of the head portion of the part are located on the same cylindrical surface, the tool body is fixed on a lathe, and multiple parts can be machined one time in a turning mode. Compared with a traditional machining mode, the machining tool improves machining efficiency by multiple times, cutting feed of a turning cutter is continuous, and a machined arc face is low in unevenness and high in quality. Meanwhile, nuts are only needed to tension the screw rod of the part when the part is assembled and clamped, no external force is adopted to clamp the screw rod of the part, and the fact that the screw rod is prevented from being damaged is guaranteed.

Description

The processing tool of screw rod end band circular arc head class part
Technical field
The utility model relates to a kind of frock, and is particularly a kind of for the screw rod end processing tool with circular arc head class part.
Background technology
The screw rod end is with the part of circular arc head, and the traditional diamond-making technique of the arc surface of circular arc head mainly contains two kinds: the one, clamp screw rod with dividing head on milling machine, and adopt milling mode to process arc surface; The 2nd, adopt interpolating method to process arc surface in vertical machining centre; But no matter adopt aforementioned the sort of method all to have following imperfect manufacture:
1. once can only process a part, working (machining) efficiency is low.
2. add feed continuously in man-hour, process to such an extent that the arc surface roughness is high, arc surface is of poor quality.
3. traditional handling ease is damaged threaded portion.
The utility model content
In view of this, the purpose of this utility model is to provide the processing tool of a kind of screw rod end band circular arc head class part, and it can realize that a plurality of workpiece process simultaneously, and improves the arc surface crudy, can solve the shortcoming that tradition processing exists.
The processing tool of the utility model screw rod end band circular arc head class part, comprise the frock body, one end of described frock body is annular, the annulus shaped part of described frock body is provided with and along the circumferential direction is arranged in juxtaposition and the locating hole adaptive with the part screw rod, the center of circle is passed in the axis prolongation of described locating hole, and the other end of described frock body is provided with the face of cylinder or the cylindrical hole face coaxial with annulus shaped part periphery.
Further, described locating hole is the screwed hole that coordinates with the part screw flight;
Further, an end that is positioned at annulus shaped part periphery at locating hole on described frock body is provided with the counterbore adaptive with part circular arc head, and the bottom surface of each counterbore equates to the distance of annulus shaped part axial line;
Further, described locating hole equidistantly has been arranged in juxtaposition 8 along annulus shaped part circumferencial direction.
The beneficial effects of the utility model: the processing tool of the utility model screw rod end band circular arc head class part, part is packed in locating hole, the arc surface of part head just is on the same face of cylinder, the frock body is fixed on lathe, can be by a plurality of parts of mode time processing of Vehicle Processing, with respect to traditional processing mode, working (machining) efficiency significantly improves, and the feed of turning process tool is continuous, and the arc surface roughness that processes is low, and the arc surface quality is high; Simultaneously only need to strain the part screw rod by nut during parts fixation and get final product, do not adopt external force clamping part screw rod, can guarantee that screw rod is not damaged.
Description of drawings
Fig. 1 is the axial cutaway view of the processing tool of this screw rod end band circular arc head class part;
The end view of this frock of Fig. 2 after the fit on workpiece.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the processing tool of the present embodiment screw rod end band circular arc head class part, comprise frock body 1, one end of described frock body 1 is annular, the annulus shaped part of described frock body 1 is provided with and along the circumferential direction is arranged in juxtaposition and the locating hole 2 adaptive with the part screw rod, the center of circle is passed in the axis prolongation of described locating hole 2, and the other end of described frock body 1 is provided with the face of cylinder 3 coaxial with annulus shaped part periphery.
Add man-hour, part is packed in locating hole 2, nut 4 is suspended in part screw rod end, by nut 4, part is strained and fixed on frock body 1; After clamping is completed, the arc surface of part head just is on the same face of cylinder.The face of cylinder 3 on frock body 1 other end is the clamping datum level that coordinates with the lathe jaw, and frock body 1 is fixed on lathe, can go out a plurality of parts by the mode time processing of Vehicle Processing; Adopt this frock to process this type of part, with respect to traditional processing mode, working (machining) efficiency significantly improves.And the feed of turning process tool is continuous, and the arc surface roughness that processes is low, and the arc surface quality is high; Only need get final product by nut 4 tension part screw rods during parts fixation simultaneously, not adopt external force clamping part screw rod, can guarantee that screw rod is not damaged.Certainly in different embodiments, the other end of frock body 1 also can arrange the cylindrical hole face replacement face of cylinder 3 with 3 same functions in the face of cylinder, coordinates by cylindrical hole face and lathe jaw, also can realize the function of this frock.
As the improvement to the present embodiment, described locating hole 2 is the screwed hole that coordinates with the part screw flight, and part is tightened in screwed hole, can further ensure the reliability that part is fixing, avoids part vibration-generating in process, can improve crudy.
As the improvement to the present embodiment, an end that is positioned at annulus shaped part periphery at locating hole 2 on described frock body 1 is provided with the counterbore 5 adaptive with part circular arc head, the bottom surface of each counterbore 5 equates to the distance of annulus shaped part axial line, the part that certain positional relationship is arranged in a circumferential direction for part circular arc surface, counterbore 5 can limit the circumferential position of part, guarantees machining accuracy.
As the improvement to the present embodiment, described locating hole 2 equidistantly has been arranged in juxtaposition 8 along annulus shaped part circumferencial direction; But the present embodiment frock time processing 8 each parts, working (machining) efficiency is high, and locating hole 2 equidistantly arranges, can make and bear more uniform impulsive force in frock and workpiece process, is conducive to protecting tool set-up and workpiece.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
