Abstract
The utility model discloses an annular slot processing tool, comprising a cutter head and a cutter holder; the cutter head is arranged at the front end of the cutter holder; wherein, a plurality of chamfering angles are arranged at the lateral side of the front end of the cutter holder, or the lateral side of the front end of the cutter holder is arc-shaped. A cutter pad is arranged at the bottom part of the cutter head; and the cutter head and the cutter pad are connectively fixed with the cutter holder through a pin. A pressure plate is arranged at the rear part of the cutter head and connectively fixed with the cutter holder through a bolt. Through the chambering angles at the front end of the cutter holder, the utility model can prevent the interference between the cutter holder and an outer ring of the annular slot in the processing and can be used to process vertical annular slots at the middle parts or end parts of shaft components or to process radial slots, with a wide application range. The utility model has simple structure, strong feasibility and high production efficiency, which can easily remove the scrap irons.
Description
Technical field
The utility model relates to a kind of machine tool, is specifically related to a kind of cannelure process tool.
Background technology
Vertical ring channel structures often appears in the design of the main shaft of the hydraulic turbine, and the machine direction that cuts the groove cutter commonly used is for radially, and when radially cutting the groove cutter processing vertical cannelure on main shaft, knife bar can be run into workpiece, can not carry out the processing of vertical cannelure with this.
China utility model patent specification CN200942431Y (September 5 2007 day for announcing) discloses " a kind of annular deep trouth turning cutting tool ", and this cutter only can be used at workpiece end processing cannelure, and can't be used for the machining at the workpiece middle part.
The utility model content
Technical problem to be solved in the utility model provides a kind of cannelure process tool, and it can be used for processing vertical cannelure at the middle part of axle class part or end.
For solving the problems of the technologies described above, the technical solution of the utility model cannelure process tool is:
Comprise cutter head, knife bar, cutter head is arranged at the front end of knife bar; It is characterized in that: the side that the side of described knife bar front end is provided with a plurality of chamferings or knife bar front end is an arc.
Described cutter head bottom is provided with edge bearing, and cutter head, edge bearing are connected and fixed by pin and knife bar.
Described cutter head rear portion is provided with pressing plate, and pressing plate is connected and fixed by screw and knife bar.
Width difference before and after the described knife bar, the width of knife bar front portion is greater than the width at rear portion.
The technique effect that the utility model can reach is:
The utility model is by establishing chamfering in the side of knife bar front end, can avoid that the outer ring of knife bar and cannelure interferes in process, can be used for processing vertical cannelure in the middle part or the end of axle class part, also can be used for processing radial slot, and the scope of application is wide.
The utility model is simple in structure, exploitativeness is strong, the eliminating iron filings are convenient, production efficiency is high.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model cannelure process tool;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the side view of Fig. 1;
Fig. 4 is the partial enlarged drawing of cutter head.
Among the figure, 1 cutter head, 2 edge bearings, 3 pins, 4 pressing plates, 5 screws, 6 knife bars, 7 chamferings.
The specific embodiment
As shown in Figures 1 to 4, the utility model cannelure process tool comprises cutter head 1, knife bar 6, and cutter head 1 is arranged at the front end of knife bar 6, the width difference of knife bar 6 front and back, and the width of knife bar 6 front portions is greater than the width at rear portion.A side of knife bar 6 front ends is provided with a plurality of chamferings 7, and these a plurality of chamferings 7 form an approximate arc.The radian that should be similar to arc is decided according to the diameter of vertical cannelure.Also can all establish a plurality of chamferings 7 in two sides of knife bar 6 front ends.
The side of knife bar 6 front ends shown in Figure 1 is provided with three chamferings 7.
The side of knife bar 6 front ends also can be arc.
During processing work, cutter head 1 of the present utility model is positioned the working position of workpiece, makes the workpiece rotation, make the length feed of the utility model simultaneously, can on workpiece, process vertical cannelure along workpiece.The utility model can be processed vertical cannelure in the middle part or the end of axle class part.Also can be used for processing radial slot, the scope of application is wide.
The side of the utility model knife bar 6 front ends is provided with chamfering 7, adds the outer ring side that the side that will be provided with chamfering 7 man-hour places cannelure, so just can avoid in the process knife bar 6 and the outer ring of cannelure to interfere.
The width of knife bar 6 front portions makes cutter have certain elasticity and intensity when processing work greater than the width at rear portion.
The utility model is simple in structure, exploitativeness is strong, the eliminating iron filings are convenient, production efficiency is high.
Claims (5)
