On the other hand, numerical control cutting machine is very high to the requirement of precision, vertically precision has determined the various aspects of performance of entire machine, as vertical linearity of machine, machine vertically the diagonal precision of returning initial point precision, machine, vertical back and forth straight line registration or the like of operation, this has just proposed very high request to the level that the workman installs longitudinal rail and tooth bar.The difference of the machine performance that brings for the difference of the installation level that remedies this respect and eliminating because gear that long-time rack-and-pinion engagement may bring and the gap between tooth bar and to the influence of the vertical precision of machine, digital control flame/CUT industry has generally adopted the rotation seat 4 that can adjust gear and tooth bar engagement automatically, this mechanism with the fixing stiff end 3 of big vehicle frame 9 be rotating shaft 2, utilize screw rod 8 to be fixed on the compression spring 7 of big vehicle frame 9, the other end is adjusted stiff end, gear 5 position between two ends, meshing of the power that provides by motor uni-drive gear box 1 with tooth bar 10, after this rotation seat 4 of installation guarantees gear 5 and tooth bar 10 correct engagement, adjust the compression spring 7 of stiff end, allow thrust reach 100KG, guaranteed that like this gear 5 and tooth bar 10 can both realize tight mesh in any position of vertically operation, thereby can guarantee vertical a plurality of precision of above-mentioned cutting machine, see Fig. 1 and Fig. 2.
Because this mechanism provides more perfect solution to above-mentioned problem,, obtain the approval of quite a few producer so application is commonplace.But because the part kind that the need at rotating shaft 2 positions are made is more, comprise copper sheathing, copper packing, rotating shaft, holder, rotation seat, these parts are formed a dimension chain, the accumulated error of whole dimension chain is bigger, perhaps gear and tooth bar mesh repeatedly, also be easy to generate the gap at rotating shaft 2 places, because the existence in gap, be difficult to guarantee the axis of rotating shaft 2 and holder 3 axially bored lines with one heart, thereby make the parallel of the field of conjugate action that is difficult to guarantee between gear and the tooth bar, the cooperation instability of driving face reliably can be brought the vibration of machine, and the variation that has the cutting ripple and bring dimensional accuracy when being reflected in cutting will guarantee that so vertical stable accuracy of machine is reliably relatively more difficult.Why this mechanism can exist the problems referred to above, the compression spring fixed end of the rotation seat 4 that has its source in rotating shaft 2 parallel directions on location not, become the state of a similar cantilever.
Summary of the invention
At above problems of the prior art, the invention provides a kind of flexible vertically driving mechanism positioner that is used for numerical control cutting machine, can steadily move in the axle center in the time of can guaranteeing that gear under normal circumstances meshes with longitudinal rack, can well guarantee that also machine is at synthesis precision longitudinally.Concrete technical scheme is as follows:
The vertical driving mechanism positioner of a kind of flexibility comprises the adjustment seat that is installed on the big vehicle frame.The upper surface and the lower surface of this adjustment seat have top wire hole respectively.Be provided with the jackscrew that is used to prop up the compression spring terminal in this top wire hole.
Among the present invention, the material of described jackscrew is a copper, can improve the friction phenomenon between jackscrew and the rotation seat.Concrete technical scheme is as follows:
The invention has the beneficial effects as follows: the adjustment seat among the present invention is fixed on the vertically big vehicle frame by soket head cap screw, after the state an of the best is transferred in the engagement of the vertical gear of machine and tooth bar, by adjusting seat jackscrew up and down, what make the compression spring terminal does not have the play gap up and down, thereby guaranteed can steadily to move in the axle center when gear under normal circumstances meshes with longitudinal rack, the synthesis precision of machine vertically just is being guaranteed.
