Abstract
The utility model relates to a differential transmission mechanical sliding table with lead screws and nuts, belonging to the driving mechanism of the dedicated lathe and combination lathe. In order to overcome the defects of complicated structure and high processing cost existing in the widely adopted mechanical sliding table with planet gear, worm gear and worm screw speed change mechanism presently, in the utility model, a zygote (5) which can engage and disengage with a gear box (6) and a gear (7), a gear (3), a gear (16), the gear (7) and a gear (14) are adopted to form a leading screw and nut differential mechanism, wherein, the gear (3) and the gear (16), and the gear (7) and the gear (14) are respectively engaged and the teeth numbers are unequal. Thus the stably-feeding, the fast forward, the fast rewind, etc of a work bench can be realized. Thereby, the structure is simplified; the transmission efficiency is improved; the manufacturing cost is reduced.
Description
The utility model belongs to the transmission mechanism of special purpose machine tool and building-block machine, is specifically related to a kind of mechanical skid plateform that adopts the feed screw nut differential drive mechanism.
Mechanical skid plateform is as power part.On special purpose machine tool and building-block machine, be extensive use of, and reached the seriation degree.The structure of present widely used mechanical skid plateform is to be changed by the planet tooth as shown in Figure 2, and drive disk assemblies such as worm gear, worm screw and fast, slow-motion two motors are formed.The existing problem of this kind mechanism is a complex structure, transmission chain length, processing cost height.
The purpose of this utility model is to provide a kind of designs simplification, and driving-chain is short, the feed screw nut differential drive mechanism that efficient is high, thus substitute traditional mechanical skid plateform.
Design concept key of the present utility model is that replacing traditional mechanical skid plateform with the feed screw nut differential speed variator utilizes principal and subordinate's transmission to realize the labyrinth of speed change merely.Below in conjunction with accompanying drawing concrete structure of the present utility model is described.Accompanying drawing 1 is a structural representation of the present utility model.Leading screw 1 usefulness bearing is installed on the transmission case 6 with the lathe bed one, is installed on the gear-box 17 with workbench 2 one with the supporting nut 4 of leading screw 1, a gear 7 that can rotate is arranged, the joint element 5 that connects with a free-sliding spline on leading screw 1.An affixed gear 3 is arranged on nut 4.Affixed gear 14 and 16 on the splined shaft 15, gear 16 can endwisely slip along spline.Joint element 5 moves axially in the control lower edge of spring and electromagnet 9, realizes and gear 7 clutch of transmission case 6.When joint element engaged with gear 7, gear 7 drove leading screws 1 and rotates together, this moment when two groups meshed gears 3 and 16,7 and 14 the number of teeth do not wait separately, thereby then produce the differential speed change purpose that reaches of leading screw 1 and nut 4.If the number of teeth of gear 3,16,14 is 100, the number of teeth of gear 7 is 101, and then splined shaft 15 rotates a week, relatively rotates a tooth between the feed screw nut, i.e. one of percentage week.This feeding at a slow speed that has just realized workbench is moved, when joint element 5 at electromagnet 9, leading screw 1 can not rotate when gear lever 8 effect moved to left down and engages with transmission case 6, feed screw nut has not had differential, workbench acquisition fast moving.
By above description as can be seen, the utility model only just can finish at a slow speed with two pairs of gears that the worker advances F.F., working cycles such as rewind down.Thereby saved drive disk assemblies such as the planetary gear worm screw of traditional mechanical skid plateform and quick electric machine, by contrast, the utlity model has simple in structure as can be seen.Make the low advantage of easy processing cost.Through on probation on certain internal-combustion engine plant's production miller, proving effect is good.
