The tool comprises a tool handle and a tool bit, wherein a notch is uniformly formed in the radial outer peripheral surface of the tool bit, a tool mounting groove is respectively formed in the groove wall on one side of the notch, the tool mounting groove is inclined in the upward direction along the inclined direction, and a blade movably connected with the tool mounting groove is arranged inside the tool mounting groove.
Description
Technical Field
The utility model relates to a steel piston processing equipment technical field specifically is a ball head sword for processing outer chamfer of steel piston pin hole.
Background
In the process of machining the steel piston, the ball-end cutter is required to be used for machining a chamfer on the outer side of a pin hole of the steel piston under the driving of the power mechanism, however, the currently used ball-end cutter only comprises one blade, so that the machining efficiency is low, and the blade and the handle of the ball-end cutter cannot be detached, so that the ball-end cutter needs to be replaced regularly, and the use cost is increased.
SUMMERY OF THE UTILITY MODEL
Low to current bulb sword machining efficiency, it is many to change the frequency, leads to the problem that use cost is high, the utility model provides a be used for processing outer chamfer of steel piston pin hole and use bulb sword, its work efficiency is higher, and its blade demountable installation is on the handle of a knife simultaneously, and convenient the change, then whole use cost is lower.
The technical scheme is as follows: the utility model provides a ball head sword for processing outer chamfer of steel piston pin hole, its includes handle of a knife and tool bit, its characterized in that: notches are uniformly formed in the radial outer peripheral surface of the cutter head, cutter mounting grooves are formed in the groove wall on one side of each notch, the cutter mounting grooves are inclined in the obliquely upward direction, and blades which are movably connected are arranged in the cutter mounting grooves;
it is further characterized in that: the blade is a sheet-shaped square blade, and cutting edges are arranged along four right-angle edges of the blade;
the three notches are uniformly arranged along the periphery of the cutter head;
an arc chamfer is arranged at the bottom of the blade mounting groove, and the inclination angle of the blade mounting groove and the horizontal direction is 20-30 degrees;
the center of the blade is provided with a through hole, the corresponding position of the cutter mounting groove is provided with a matched positioning hole, and a fixing bolt penetrates through the through hole and the mounting hole.
After having adopted above-mentioned structure, because the tool bit periphery is equipped with the breach of evenly arranging, the breach is inside to be equipped with the cutter mounting groove respectively, has arranged the blade respectively through this cutter mounting groove, then this bulb sword during operation's efficiency is higher, blade and cutter mounting groove swing joint simultaneously, then easy dismounting have prolonged the life of this bulb sword, have reduced use cost.
Drawings
FIG. 1 is a front view of the overall structure of the present invention;
FIG. 2 is an enlarged schematic view of a portion of the structure of FIG. 1 according to the present invention;
FIG. 3 is a left side view of the overall structure of the present invention;
in the figure: 1. a knife handle; 2. a cutter head; 21. a notch; 22. a cutter mounting groove; 3. a blade; 31. and a through hole.
Detailed Description
As shown in fig. 1 to 3, a ball end mill for processing outer chamfer of steel piston pin hole, includes handle of a knife 1 and tool bit 2, and tool bit 2 is the column, evenly offers breach 21 along the radial outer peripheral face of tool bit 2, is equipped with cutter mounting groove 22 respectively along the outside of breach 21 one side cell wall, and cutter mounting groove 22 inclines along the direction of slant, and cutter mounting groove 22 is inside to be equipped with swing joint's blade 3. Because a plurality of breachs 21 have evenly been arranged to tool bit 1 periphery, and every breach 21 is inside to be equipped with blade 3 respectively through cutter mounting groove 22, then this bulb sword work efficiency is higher under outside power unit's the drive, and blade 3 and cutter mounting groove 22 swing joint then it is convenient to change the blade simultaneously, have reduced use cost.
Preferably, blade 3 is lamellar square blade, all is equipped with the cutting edge along four right-angle sides of blade 3, through square, the setting of blade 3 that is equipped with the cutting edge all around respectively, then blade 3 one side cutting edge just can rotate the cutting edge on other limits and continue to use after using a period of wearing and tearing to can further improve the life of this bulb sword, reduce use cost.
Preferably, the notches 21 are provided in three and are evenly arranged along the periphery of the cutting head 2.
Preferably, the bottom of the blade mounting groove 22 is provided with an arc-shaped chamfer to prevent the cutting edge of the blade 3 from being worn, and meanwhile, the angle of inclination of the blade mounting groove 22 to the horizontal direction is 20 ° to 30 °, and then the angle of inclination of the blade 3 mounted thereon in a matching manner is 20 ° to 30 °, so that the blade 3 is easier to cut and has a small wear amount.
Preferably, the center of the blade 3 is provided with a through hole 31, a corresponding position of the tool mounting groove 22 is provided with a matching positioning hole (not shown), and a fixing bolt (not shown) is provided through the through hole 31 and the mounting hole, so that the blade 3 can be conveniently disassembled and assembled by screwing or loosening the bolt.
The above description is only for the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
