The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the right-angle milling head of a kind of compensating coaxial degree of the present invention error.
Referring to accompanying drawing 1, a kind of right-angle milling head of compensating coaxial degree error, comprise housing, vertical axis, bevel gear group and trunnion axis 26, described vertical axis meets at right angles with described trunnion axis 26 by described bevel gear group and is connected, described vertical axis and described trunnion axis 26 are installed in the described housing by bearing is rotatable, and described vertical axis comprises vertical axis 5, following vertical axis 17 and a yielding coupling.Described yielding coupling comprises the shaft coupling first half 9 and shaft coupling Lower Half 13, keeps certain clearance between two ones up and down, and the described vertical axis 5 of going up is by described yielding coupling and described following 17 coaxial connections of vertical axis.The coaxiality error that machine tool chief axis 4 passes to vertical axis 5 is compensated by yielding coupling; Yielding coupling can be a yielding coupling commonly known in the art, is used for compensating coaxial degree error.
Owing to cause disalignment between machine tool chief axis 4 and the vertical axis during assembling of right-angle milling head and lathe, make that producing radial load when right-angle milling head work is loaded into spool getting on element of right-angle milling head, make spool to be in the bad working environment with element key, bearing etc.In enforcement of the present invention, vertical axis is divided into vertical axis 5 and following vertical axis 17, last vertical axis 5 is used to connect vertical axis 17 and machine tool chief axis 4 down, like this, just can increase a yielding coupling between last vertical axis 5 and following vertical axis 17 and be addressed the above problem.Described yielding coupling can make the radial load that produces because of coaxiality error between machine tool chief axis 4 and the vertical axis be compensated, and has improved the working environment of axle with element.
Referring to accompanying drawing 2, after having solved the radial load that causes because of coaxiality error, machine tool chief axis 4, last vertical axis 5, can produce axial displacement on shaft coupling and the following vertical axis 17 formed axis, the axial displacement meeting influences the machining accuracy of right-angle milling head, in order to solve the axial displacement of coaxiality error and yielding coupling simultaneously, in order to utilize the pulling force of machine tool chief axis broaching tool device 1, the present invention improves yielding coupling: use a yielding coupling to connect vertical axis 17 and last vertical axis 5 and machine tool chief axis 4 down, cooperate a cover by pulling-on piece 14(referring to accompanying drawing 4) and the semicircular ring joint formed of screw 16 come compensating coaxial degree error, utilize the pulling force of machine tool chief axis broaching tool, eliminate axial displacement.In shaft coupling Lower Half 13 through hole by its axis is set, a recessed edge of semicircle or convex moulding 43 are formed at the bottom in described shaft coupling Lower Half 13, the shaft coupling first half 9 and shaft coupling Lower Half 13 couple together by elastomer, described shaft coupling Lower Half 13 and following vertical axis 17 coaxial fixedlying connected, the described shaft coupling first half 9 and last vertical axis 5 coaxial fixedlying connected.The right-angle milling head of a kind of compensating coaxial degree of the present invention error also comprises a pulling-on piece 14, described pulling-on piece 14 is provided with the recessed edge of semicircle or convex moulding 43 corresponding convex mouldings or the recessed edge 44 of semicircle with described shaft coupling Lower Half 13 bottoms, and described pulling-on piece 14 is fixed on described going up on the vertical axis 5 by a through hole that passes described shaft coupling Lower Half 13 with screw 16 is coaxial.
Accompanying drawing 3 is the shaft coupling Lower Halves 13 after improving, and also sets up a convex moulding in its underpart.The shaft coupling first half 9 cooperatively interacts with last vertical axis 5, by flat key 7 transmitting torques.Yielding coupling in the axial direction can displacement, has increased screw 16 here, and the screw of optional M24 * 1.5 passes pulling-on piece 14(referring to accompanying drawing 4) and shaft coupling Lower Half 13 in through hole screw in go up vertical axis 5(referring to accompanying drawing 5).So both limited the axial displacement of the shaft coupling first half 9 and following vertical axis 17, the binding face by two semicircles has guaranteed that also last vertical axis 5 can swing within the specific limits, has compensated coaxiality error.Will maintain certain clearance in the shaft coupling first half 9 and the shaft coupling Lower Half 13, be used to provide the space and swing, in actual conditions, this swing is very little concerning flexible member, can not influence the life-span of shaft coupling.
Further, one boss platform 42 is set, the installation that matches with the outer surface of following vertical axis 17 ends of the inner surface of boss platform 42 in the yielding coupling Lower Half.Because also can there be same axis error in the installation that cooperates between yielding coupling and the following vertical axis 17, so boss platform 42 is set in shaft coupling Lower Half 13, the installation of boss platform 42, the axiality that can guarantee yielding coupling and following vertical axis 17 is within a relative less error range.
Further, can reinforcement be set on shell, the right-angle milling head whole rigidity be had significantly rise.
The course of work of the right-angle milling head of a kind of compensating coaxial error of the present invention is, machine tool chief axis 4 is by keyway (referring to the accompanying drawing 5) transmitting torque on the last vertical axis 5, pass to the shaft coupling first half 9 and shaft coupling Lower Half 13 by last vertical axis 5 by flat key 7 then, pass to down vertical axis 17 by the shaft coupling first half 9 and shaft coupling Lower Half 13 again, pass to vertical axis bevel gear 39 then, pass to trunnion axis bevel gear 31 again, then pass to trunnion axis 26, drive by trunnion axis 26 at last and be contained in the milling head rotation of replacing handle of a knife 27 positions, thereby realize that right-angle milling head is to the processing on the part vertical plane.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle 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.
