Description
Technical field
Content of the present invention belongs to the linear actuator technical field, relates to the telescopic ball-screw of a kind of numerical control three joints top.
Background technology
Ball-screw in the ball screw secondary member is a non-telescoping body at present, and namely thick stick body absolute length is certain, and it just can't use in limited space like this.Jack is two nodel line drivings device, but the transmission limited space that it can be saved, only to save a half space and it can accurately not located.In the production reality, under some special operation conditions, just be sought after the larger space of saving of to stretch and accurately locate and can bear again the Linear transmission element of large load.For example: rod member need to have the strong point at certain distance when numerical control inward turning milling machine tool milled longer trapezoidal screw, and when revolving milling head and go to the strong point, the strong point can automatic folding shrinks back to allow and revolves milling head and pass through, the strong point was stretched up the righting screw mandrel again after milling head to be revolved was gone over, and the leading screw external diameter of processing is in different size, and the height of the strong point is different, can stretch on a large scale so need one, can accurately locate again, and the linear actuator of digit control support.Obviously, prior art products also is difficult to satisfy the work requirements of above-mentioned special operation condition.
Summary of the invention
The object of the invention is to the problem that prior art exists is solved, and then a kind of rational in infrastructure, dependable performance, good rigidly, driving efficiency and precision height, accurate positioning are provided, can save than large space and the telescopic ball-screw of numerical control three joints that can bear large load and push up.
For achieving the above object, the technical solution that the designer adopts is to utilize the high precision of ball screw assembly,, high rigidity, high driving efficiency and Linear transmission characteristic also are designed to the telescopic ball-screw of numerical control three joint top according to the large young pathbreaker's ball-screw of certain nominal diameter, this ball-screw top is by base, servomotor, synchronous belt pulley, from outside to the single order drive socket of interior coaxial setting, second order ball-screw sleeve, three rank ball-screws and the second order ball nut and the compositions such as three rank ball nuts that are fixedly connected on second order ball-screw sleeve upper end that are fixedly connected on single order drive socket upper end, servomotor drives the single order drive socket along the stack shell axial rotation by synchronous belt pulley; Second order ball-screw sleeve and second order ball nut thread set (consist of second order ball screw assembly) also stretch in the single order drive socket, are respectively equipped with on the second order not-go-end pin under the not-go-end pin and second order in the top and bottom of second order ball-screw sleeve outer wall; Three rank ball-screws and three rank ball nut thread sets (consisting of three rank ball screw assembly,s) also stretch in the second order ball-screw sleeve, are respectively equipped with on three rank not-go-end pin under the not-go-end pin and three rank in the top and bottom of three rank ball-screw outer walls.In the real work, servomotor drives the single order drive socket by synchronous belt pulley transmission and rotates, and the single order drive socket is to captive joint with the second order ball nut, does fore and aft motion so promote second order ball-screw sleeve; When the relative second order ball-screw of second order ball nut sleeve moved on the second order not-go-end pin or lower not-go-end pin, the second order ball nut no longer rotated relative to second order ball-screw sleeve; Three rank ball nuts are to captive joint with the second order ball-screw, do fore and aft motion so promote again three rank ball-screws; When the relative three rank ball-screws of three rank ball nuts moved on three rank not-go-end pin or lower not-go-end pin, three rank ball nuts no longer rotated relative to three rank ball-screws, finally play the effect of linear extendible transmission.The rotation direction of second order ball screw assembly, and three rank ball screw assembly,s is consistent in the work, namely is both dextrorotation or is both left-handedly, and helical pitch is equally large.
Technical solution of the present invention also comprises: two single order anti-rotation guiding column jeckets are uprightly arranged on base, the top of two single order anti-rotation guiding column jeckets respectively is connected to the both sides of second order ball nut by a cover deep groove ball bearing spare symmetry, each plug-in mounting enters a second order anti-rotation guiding column jecket in two single order anti-rotation guiding column jeckets, the top of two second order anti-rotation guiding column jeckets respectively is connected to the both sides of three rank ball nuts by a cover deep groove ball bearing spare symmetry, each plug-in mounting enters three rank anti-rotation guideposts in two second order anti-rotations guiding column jeckets, and the upper end of two three rank anti-rotation guideposts is by connecting rod or win in succession and captive joint with the top of three rank ball-screws.The effect that the anti-rotation guidepost is set in device is in order not allow three rank ball-screws rotate: single order anti-rotation guiding column jecket is connected with the second order ball nut by deep groove ball bearing, keeps the second order ball nut to rotate; Second order anti-rotation guiding column jecket by deep groove ball bearing with are connected the rank ball nut and connect, when the second order ball nut rotated, lead column jecket and second order ball-screw sleeve of second order anti-rotation done telescopic moving; Three rank anti-rotation guideposts are to captive joint with three rank ball-screws, and when three rank ball nuts rotated, three rank anti-rotation guideposts and three rank ball-screws were done telescopic moving.Between anti-rotation guidepost and the ball nut deep groove ball bearing is housed, has increased like this rigidity of anti-rotation guidepost.
Compared with prior art, of the present invention have a following advantage:
One, the present invention is a kind of element that can change into rotatablely moving Linear transmission, can stretch in the real work and save larger space;
Two, the second order among the present invention and three rank driver elemenies are ball screw assembly,s, can increase the parameters such as the carrying columns of ball screw assembly, and ball size according to actual requirement and can bear larger load;
Three, the telescopic ball-screw of this numerical control three joints top has the high precision of ball screw assembly,, high rigidity, high driving efficiency, can the numerically controlled automatic operation;
Four, because accuracy, the superficial hardness of lead screw pair raceway are the special construction steel in HRC58～62 and material, thereby have long service life;
Five, maintenance simple in structure, easy of the present invention is under most operating modes, as long as carry out general lubricated and dust-proof working.
