Fig. 1: the schematic front view of drilling rod;
Fig. 2: schematic diagram is looked on a left side for drilling rod;
Fig. 3: the D of operate portions is to partial schematic diagram;
The A-A cross-sectional schematic of Fig. 4: Fig. 1;
The B-B cross-sectional schematic of Fig. 5: Fig. 2;
Fig. 6: the application schematic diagram of cold pair of screw lock crown drilling rod in Y shape.
Detailed description of the invention
As shown in Figure 1, Figure 2, Fig. 3, cold pair of screw lock crown drilling rod in Y shape, drilling rod comprises the operate portions 5, neck 6 and the shank 7 that are connected mutually successively centered by same central axis, operate portions 5 is provided with helical form chip area 8, chip area 8 operationally plays and holds bits and chip removal effect, and the entity part outside chip area 8 is the knife back 9; Shank 7 is one section of cylinder that precision is higher, clamps to transmit machine power during use by handle of a knife, makes cutter rotate and possess cutting power; Neck 6 is the assembly that cone and cylinder are formed, and operationally, chip can be avoided to splash and strike handle of a knife and machine tool chief axis, play a protective role.
The axial location of drilling rod is provided with Dan Zhizhu Cooling Holes 10, is provided with two points of Cooling Holes, 11, two point Cooling Holes 11 communicates with main Cooling Holes 10 and form Y shape inner-cooling structure in the left end of operate portions; Two points of Cooling Holes form two cooling liquid outlets 12 in the left side place of operate portions; There is provided cooling fluid operationally to crown blade.
The end face of drilling rod operate portions is provided with V-type locating slot 14, and V-type locating slot 14 both sides are provided with the fastening screw 15 screwing housing screw.
As Fig. 4, the inscribed circle of knife back central authorities is drilling rod core thick 13, and the diameter of usual drilling rod core thick 13 is larger, and intensity is higher, and during work, feeding is faster; But the diameter of drilling rod core thick 13 is larger, and the space of chip area 8 is less, and chip removal ability is poorer, constraining the further raising of feed speed on the contrary, is ensure drill bit intensity, the diameter of main Cooling Holes 10 be drilling rod core thick 1/3 ~ 1/2.
As Fig. 5, V-type locating slot 14 is in order to the location to crown blade, and the angle of the V-type locating surface of V-type locating slot is 90 ° ~ 140 °.The fastening screw 15 of V-type locating slot both sides is in order to fastening crown blade.
As Fig. 6, when assembling, the axis coaxle of the axis of half shoulder hole of crown blade 2 and the fastening screw 15 of drilling rod 1, housing screw 3 screws in fastening screw 15, is closely fixed on drilling rod 1 by crown blade 2.
It is simple that drilling rod adopts cold access structure in Y shape to have structure, the advantages such as production cost is low, and its shank and cutter hub are single straight hole, and aperture is slightly large, and lead to bit operation region by the inclined hole that two apertures are slightly little; In Y shape, cold pair of screw lock crown drilling rod adopts V-arrangement location structure, production precision is easy to ensure, can reduce the production cost of crown blade and drill bit knife bar, V-arrangement location structure contact surface is large, crown blade positioning precision on drill bit knife bar is high, clamping good reliability.Two screw lock structure, auxiliary screw kind is many, supporting advantage of lower cost.
It is to be understood that: the above is only the preferred embodiment of the present invention; for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
