Abstract
The utility model relates to a five-shaft floating pressure drilling machine for drilling on a curved surface workpiece. The five-shaft floating pressure drilling machine comprises a drilling machine body and a floating pressure group. When the five-shaft floating pressure drilling machine is in use, after the position and the angle of a drill bit group are respectively positioned, the drill bit group together with the floating pressure group moves towards the workpeice; a floating pressure part of the floating pressure group is positioned on the axial outer side of a drill bit of the drill bit group, so that a floating pressure part is propped against the workpiece and further presses the workpiece on a workpeice placing platform; then the drill bit group continuously moves towards the direction of the workpeice and the floating pressure part is inwards retracted relative to the floating pressure body and is kept propped against the workpiece. Therefore, when the drill bit is contacted with the workpiece, the workpeice is pressed on the workpiece placing platform by the floating pressure part, so that the workpiece can be effectively fixed, the vibration of the workpiece during drilling is reduced, further burrs in holes are avoided, and the drilling quality is improved.
Description
Technical field
The utility model relates to a kind of facility of boring, refers to the floating drilling machine of pressing of a kind of five of on the curved surface working substance, holing especially.
Background technology
Five drilling machines are a kind ofly can produce relatively axially that the drill bit straight line move effect and along two axial drilling machines of generation drill bit rotating effects relatively along three; Wherein three straight line shifting axles are respectively X, Y, Z axle and move the unit; Two turning cylinders then for get in A, B, three turning cylinder unit of C axle its two; Wherein A, B, C axle are respectively the rotating shaft that rotates around X, Y, Z axle, and five drilling machines have following three kinds of kinds through the kind of two turning cylinder unit and the collocation of position:
One of which, see also shown in Figure 10, the cutter rotary type, wherein glove platform 911 can be done moving of Y direction, and drill bit 912 can be done the rotation of moving of X, Z direction and B, C direction.
Its two, see also shown in Figure 11, the platform rotary type, wherein glove platform 921 can be done the rotation of A, C direction, and drill bit 922 can be done moving of X, Y, Z direction.
Its three, see also shown in Figure 12, mixed type, wherein glove platform 931 can be done the rotation of moving of Y direction and C direction, and drill bit 932 can be done the rotation of moving of X, Z direction and B direction.
Five drilling machines reach through five axial moving and rotate, and can on the curved surface of working substance, hole; Three shifting axle unit relatively move the position of drill bit to the location, and two turning cylinder unit then make the angle of drill bit can be right against the normal of curved surface drill hole; After position and angle all arrive the location, the same moved further through three shifting axle unit at last, so that drill bit moves towards curved surface along this normal direction, and the rotation through drill bit itself is to hole on curved surface.
Yet five drilling machines of prior art have following two shortcomings:
The first, when drill bit rotates when boring on working substance, will certainly because of drill bit on working substance pivoting friction and make working substance produce certain relative vibration, and working substance is in case after the vibrations, just might make the hole that gets out produce burr.
The second, no matter be any five drilling machines of above-mentioned three kinds of patterns, its three shifting axle unit have all occupied whole most volume of facility and weight; Therefore at last through three shifting axle units synchronization move make drill bit relative to along normal when curved surface moves; If the excessive velocities of shifting axle unit; Then may produce excessive momentum and inertia force because of the preponderance of said shifting axle unit, and then the degree of accuracy of influence boring; So three last synchronization-moving velocity potentials in shifting axle unit must reduce keeping the boring quality, but have therefore sacrificed whole drilling efficiency also.
The utility model content
Because five drilling machines of aforementioned prior art are difficult to avoid the hole that gets out to produce the shortcoming of burr, the utility model provides a kind of five floating drilling machines of pressing, and it can effectively solve this shortcoming.
For reaching above-mentioned creation purpose, the technological means that the utility model adopted is a kind of five floating drilling machines of pressing of design, wherein comprises:
One drilling machine body, it includes three shifting axle unit, two turning cylinder unit, a glove platform and bit sets; Three shifting axle unit and two turning cylinder unit are located between bit sets and the glove platform, and bit sets and glove platform can be done three axial relatively move and two axial relatively rotates; Bit sets includes a drill bit power part and a drill bit, and the drill bit power part orders about drill bit and rotates;
One floating pressure group, it is located on the bit sets of drilling machine body, floating pressure group includes a floating body and the floating casting die of pressing, floating casting die can float relatively in the pressure body and contract, and floating casting die in the contract rotation axially parallel of moving direction and drill bit; Floating casting die is positioned at the axial outside of the drill bit of bit sets.
When the utility model uses; After the position of bit sets and angle all arrive the location; Same moved further through three shifting axles makes the related floating pressure group of bit sets move towards working substance; And because the floating casting die of floating pressure group is positioned at the axial outside of the drill bit of bit sets, therefore floating casting die can be resisted against earlier on the working substance, and thus working substance is suppressed on the glove platform; Then since three shifting axles still towards the working substance direction with in the moved further, therefore floating casting die just can floatingly relatively gradually be pressed in the body and contracted, and still is held against on working substance; Thus when drill bit touches working substance, owing to there is floating casting die that working substance is compressed on the glove platform, with effective regular worker crop and reduce the vibrations of working substance when the boring, and then avoids the generation of burr on the hole and promote the quality of holing.
Furthermore, described five floating drilling machines of pressing, wherein three of the drilling machine body shifting axle unit are respectively X, the Z axle shifting axle unit that moves bit sets, and the y-axis shift moving axis unit of mobile glove platform; Two turning cylinders of drilling machine body are respectively B, the C axle turning cylinder unit of rotary drill bit group.
Furthermore; Described five floating drilling machines of pressing; Wherein the drilling machine body further includes one the 2nd Z axle group, and the 2nd Z axle is mounted on the drilling machine body, and can do three axial relatively move and two axial relatively rotates along with bit sets and glove platform; The 2nd Z axle group can make the bit sets straight line move, and the rotation axially parallel of the moving direction of bit sets and drill bit.
Through bit sets is arranged on the 2nd Z axle group; And the direction of the 2nd Z axle group promotion bit sets is axially coaxial with drill bit; Therefore to make bit sets at last when working substance moves, can change to organize and promote bit sets, and need not to employ three shifting axle unit by the 2nd Z axle; And the element that the 2nd Z axle group is promoted only has bit sets and floating pressure group; Its weight moves required mobile element far below three shifting axle units synchronization; Therefore drill bit be can significantly accelerate and less inertia force, momentum also kept simultaneously towards the speed that working substance moves; Not only can improve operating efficiency thus, more can keep the quality of boring.
Furthermore, described five floating drilling machines of pressing, wherein the 2nd Z axle group includes a main body and a movable plate, and main body is located on the drilling machine body, and movable plate can move relative to the main body straight line, and bit sets is located on the movable plate.
