Abstract
The utility model provides a space six-freedom working table for supporting, clamping and cutting the workpieces, which employs the structure that one side of the support adjusting rod is connected with the space working table through the universal scissors, and the other sides is connected with the low stylobate through the universal scissors. The changeable length of the support adjusting rod according to a certain relation can rotate the space working table along the X, Y, and Z axis, causing that the workpiece has an ideal position and posture corresponding to the machined head. The space working table is simple and achieves space inclined holes and cutting works of the inclined surfaces or the curved surfaces only clamps once.
Description
The utility model belongs to a kind of and is used for lathe supporting and clamping workpiece, to carry out the particularly device of metal cutting processing of material.
Existing machine tool worktable part itself generally mostly is most the motion of one degree of freedom only, when the part to hole with angle of inclination, space or plane carries out machining, usually need special-purpose auxiliary worker to press from both sides facility or workpiece is carried out multiple clamping, perhaps need special use or building-block machine with the structure relative complex.For part, only utilize the bench with single degree of freedom of machine tool then to be difficult to machine with space curved surface.
In view of this, but the purpose of this utility model provides the space six-freedom worktable that a kind of control position and attitude change, and with its supporting workpiece is installed, and only needs clamping once can finish machining to space inclined hole, inclined-plane or curved surface by associated machine tool.
Technical solution of the present utility model is: the space six-freedom worktable mainly comprises the space workbench, stylobate, the six roots of sensation support parts such as expansion link and relevant universal hinge down.Its end that supports expansion link connects with the space workbench by universal hinge, and the other end connects with following stylobate by universal hinge.The length that supports expansion link when the six roots of sensation can make the position of space workbench and attitude that corresponding the change taken place, so that processing head is finished the machining to workbench institute clamping workpiece during with certain relationship change.
Below in conjunction with accompanying drawing structure of the present utility model is described in further detail:
Fig. 1 is the schematic diagram of space six-freedom worktable.
Fig. 2 be with single-piston-rod hydraulic cylinder do to support expansion link and in the instantiation structure chart of displacement detector is housed.
With reference to accompanying drawing 1,1 is the space workbench among the figure, and 2 for supporting expansion link, and 3 be last universal hinge, and 4 are universal hinge down, 5 under stylobate.The upper end of supporting expansion link 2 connects with space workbench 1 by last universal hinge 3, and universal hinge 4 connected with following stylobate 5 under the other end passed through.Upper and lower universal hinge can give suitably determining in the distribution of space workbench and following stylobate respectively according to real work requirement and condition.Support expansion link 2 and can adopt hydraulic cylinder, also can adopt ball-screw or rack pinion.The length variations that supports expansion link 2 can realize by servo valve valve control hydraulic-driven, also can be driven by ball-screw or rack pinion and worm and gear by the control motor and realize.The table top of space workbench 1 has T-slot, so that clamping workpiece uses.The geometric shape of space table surface and the layout of T-slot can specifically be determined by actual needs.
During use, will descend stylobate 5 to be fixed on the suitable operating position of lathes such as machining center, drilling machine, milling machine, workpiece be fixed on the space workbench 1.Suitably control to adjust the length variations that supports expansion link 2 by certain relation, can make space workbench 1 respectively along x, y, z axle moving linearly with respectively around x, y, z axis rotation, any other motion of space workbench 1 all can be composited by above-mentioned six kinds of motions.Can make workpiece realize ideal position and attitude thus, reach and make workpiece can carry out the purpose of space inclined hole, inclined-plane or Machining of Curved Surface with respect to processing head.
Example shown in Figure 2 is that magnetostriction type waveguide ultrasound displacement detector (diagram only is a support expansion link structure) has been installed with single-piston-rod hydraulic cylinder work support expansion link and in hydraulic cylinder inside.The magnet ring 9 of this detector is fixed on the lower end of hydraulic cylinder piston 6, and waveguide 8 stretches in the endoporus of piston 6, and waveguide mount 10 is fixed on the lower end of hydraulic cylinder body 7.Thisly place the structure of hydraulic cylinder inside can avoid the damaged in collision of detector displacement detector, make the contour structures that supports expansion link succinct again, reduced the ratio that takies in space.Here, one of them the universal hinge in the upper and lower universal hinge is a two degrees of freedom, and another universal hinge must be Three Degree Of Freedom.Usually, hydraulic cylinder preferably adopts hydrostatic support single-piston rod form, the relative motion cooperation place of the piston of this hydraulic cylinder and cylinder body bearing all is small tapering, and there is the static pressure oilhole to communicate, form the static pressure piston and the hydrostatic bearing of this hydraulic cylinder, frictional force when it can reduce the hydraulic pressure relative motion effectively, but this low friction makes the piston of hydraulic cylinder and cylinder body except that linear relative movement, also can realize suitable relatively rotating.At this moment, upper and lower universal hinge all only needs two degrees of freedom just can satisfy the motion requirement of space six-freedom worktable, so the hydrostatic support hydraulic cylinder can make universal hinge structure be simplified.
The space six-freedom worktable structure that the utility model provides is comparatively succinct, with its supporting and clamping workpiece, only needs clamping once can realize workpiece is carried out space inclined hole, inclined-plane or curved surface cutting processing, and can make the corresponding simplification of structure of used lathe.
