The specific embodiment
In order to further specify principle of the present utility model and structure, now by reference to the accompanying drawings preferred embodiment of the present utility model is elaborated.
See also Fig. 1 to Fig. 4, the utility model provides a kind of boring head, and it comprises splined shaft 1, flange spline housing 2, belt pulley 3, sleeve 4, cylinder body fixed conveyor device 5, piston guide transmission device 6, positioning and fixing cover 7, drill bit 8 and Counterboring apparatus 9.
Splined shaft 1, first end of splined shaft 1 is provided with spline 11, and splined shaft 1 middle part is polished rod 12, the sheathed bearing of second end of splined shaft 1.The effect of splined shaft 1 is that the rotation of transmission drive drill bit 8 realizes boring and reaming, and the reason that the first end end is designed to spline 11 is being connected for convenience of splined shaft and other parts.In the present embodiment, splined shaft 1 and flange spline housing 2 are orthogonal.Design can guarantee the perpendicularity of drill bit 8 very easily like this, only need to guarantee that flange spline housing 2 and boring plane parallel get final product, and the rotation of flange spline housing 2 drive splined shafts 1 is also convenient.
Flange spline housing 2, splined shaft 1 passes flange spline housing 2, and spline 11 places of first end of splined shaft 1 and flange spline housing 2 flexibly connect, and flange spline housing 2 drives splined shaft 1 and rotates.Flange spline housing 2 plays and drives the effect that splined shaft 1 rotates, by the spline 11 of splined shaft 1 splined shaft 1 is fixed in the middle of the flange spline housing 2, make that splined shaft 1 is followed 2 rotations of flange spline housing when flange spline housing 2 rotates, and splined shaft 1 can slide along sleeve 4 directions in flange spline housing 2, and flange spline housing 2 can not limit the movement of this direction.In the present embodiment, flange spline housing 2 is fixed on the belt pulley 3 by screw.In other embodiments, the fixed form of flange spline housing 2 can be diversified.
Belt pulley 3, belt pulley 3 is fixedlyed connected with flange spline housing 2, and belt pulley 3 drives flange spline housing 2 and rotates.Belt pulley 3 drives by the driven by motor belt, because in the present embodiment, flange spline housing 2 is fixed on the belt pulley 3 by screw.
Sleeve 4, sleeve 4 are sheathed on outside the splined shaft 1 and make splined shaft 1 to move along sleeve 4 bearing of trends.Because drill bit 8 under the situation that does not have sleeve 4, is easy to cause splined shaft 1 to produce inclination at boring the time can be subjected to the being holed reaction force of material under the influence of power, in case splined shaft 1 tilts, gently then cause bore inclining to influence drilling quality, heavy then cause drill bit to fracture, accidents caused.And after sheathed sleeve 4, because sleeve 4 has limited the moving direction of splined shaft 1, make splined shaft 1 to move along sleeve 4 directions, avoided the inclination of splined shaft 1.In the present embodiment, the bearing of trend of sleeve 4 and guide groove is consistent.Be that for convenience piston guide transmission device 6 drives the movement of splined shafts 1 like this, and do not need to add extra device the movement of piston guide transmission device 6 do not turned to.In other embodiments, the direction of sleeve 4 and guide groove also can be inconsistent, adds the device that Inbound dress changes accordingly and get final product.
Cylinder body fixed conveyor device 5, cylinder body fixed conveyor device 5 is for the cylindricality of hollow and be set in outside the sleeve 4, and the side of cylinder body fixed conveyor device 5 is provided with a guide groove.Cylinder body fixed conveyor device 5 comprises upper cylinder body fixed conveyor device 51, piston/cylinder 52 and lower cylinder body holder 53, and upper cylinder body fixed conveyor device 51 is connected the two ends of piston/cylinder 52 with lower cylinder body holder 53, and guide groove is arranged on the side of piston/cylinder 52.Cylinder body fixed conveyor device 5 plays the effect of parcel and encapsulation splined shaft 1.In the present embodiment, upper cylinder body holder 51 and lower cylinder body holder 53 are connected with a connecting seat 54 respectively, in order to be connected and fixed the boring head.Connection Block 54 is provided with chute or circular hole etc. in order to be connected and fixed.
Piston guide transmission device 6, comprise a regulating handle 61 and transmission mechanism 62, transmission mechanism 62 is tubular, be set in outside the sleeve 4 and the outer ring of the bearing of conflicting, regulating handle 61 connects transmission mechanism 62 and stretches out from guide groove, drives splined shaft 1 and move along sleeve 4 bearing of trends when regulating handle 61 moves along guide groove.In the present embodiment, the end of the transmission mechanism 61 of piston guide transmission device 6 is by extended four support columns of tubular, supports the outer ring of conflict bearing.Promoting regulating handle 61 by external agency when in use just can promote whole splined shaft 1 and stretch out along sleeve.
Positioning and fixing cover 7, positioning and fixing cover 7 is set in outside the bearing of splined shaft 1.The effect that bearing is set is to allow splined shaft 1 rotate at the inner ring of bearing, and direct connection splined shaft 1 has been avoided and the frictional force influence that causes in the outer ring of piston guide transmission device 6 connection bearings then.
Drill bit 8, drill bit 8 connects the end of second end of splined shaft 1.
Counterboring apparatus 9 comprises fixed housing 91, reaming cutter 92 and limiting plate 93.
Reaming cutter 92 is set on the drill bit 8, and fixed housing 91 is set in outside the reaming cutter 92.
Limiting plate 93, limiting plate 93 is ring-type, limiting plate 93 is set in outside the fixed housing 91, is provided with a bearing between fixed housing 91 and the limiting plate 93.The effect of limiting plate 93 plays the spacing reaming cutter 92 of avoiding and too is deep in the hole.
Be that example describes operation principle of the present utility model in detail below with the present embodiment.
When boring is used, drill bit 8 is aimed at the position that needs boring, guarantee the plane parallel of flange spline housing 2 and drill hole, splined shaft 1 is just vertical with the plane of drill hole like this, at this moment starter motor drives belt pulley 3 rotations, thereby driving flange spline housing 2 rotates, flange spline housing 2 drives splined shaft 1 and rotates, splined shaft 1 drives drill bit 8 and rotates, drill bit 8 begins boring, and external agency promotes the regulating handle 61 of piston guide transmission device 6, begins mobile along sleeve 4 thereby promote splined shaft 1, so the direction that moves owing to the restriction splined shaft 1 of sleeve 4 is fixed and can not influenced by external force and is offset, thus under the situation that guarantees perpendicularity, the holing of success.
When reaming is used, reaming cutter 92 is aimed at the boring of having bored, reaming cutter 92 is inserted in the boring, then starter motor, a series of drives by belt pulley 3 drive reaming cutter 92 and rotate, and it is too dark and cause accident that limiting plate 93 can avoid reaming cutter to enter into boring.
In sum, the utility model limits the direction of motion of splined shaft by sleeve, thereby has guaranteed the perpendicularity that drill bit moves, and has solved the drill bit that causes because of the drill bit moving direction out of plumb problem that fractures.
The above only is preferable possible embodiments of the present utility model, and unrestricted protection domain of the present utility model.Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do, or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
