Abstract
The utility model relates to a mechanical sliding table type screw rod interval adjusting mechanism in a combined lathe, and belongs to the technical field of universal components of combined lathes. According to the mechanical sliding table type screw rod interval adjusting mechanism in the combined lathe provided by the utility model, an adjusting nut of the same spinning screw rod is arranged at one end of a trapezoid nut; the adjusting nut and the trapezoid nut are connected by arranging a flat key and a fixing sleeve; an interval between the former trapezoid nut and one end of a screw rod thread is changed to an inverse interval of the screw rod thread and the trapezoid nut, and the both ends of the adjusting nut by adjusting a position between the trapezoid nut and the adjusting nut through a locking nut and a gasket, so that a mechanical sliding table is stable to operate and the service life of the mechanical sliding table can be prolonged. The mechanical sliding table type screw rod interval adjusting mechanism in the combined lathe provided by the utility model has the advantages of simple structure and obvious effect and is conductive to improving the product quality and the service life.
Description
Technical field
The utility model relates to mechanical skid plateform leading screw clearance adjustment mechanism in a kind of building-block machine, belongs to the modular unit for modular machine technical field.
Background technology
The trapezoidal nut feed screw apparatus of the universal component of building-block machine---mechanical skid plateform is the transmission mechanism of mechanical skid plateform, and its effect is that rotatablely moving of gearbox output become the rectilinear motion of slide unit.More or less have the gap between nut in the former trapezoidal nut feed screw apparatus and the leading screw, and this gap increases constantly along with not the stopping to use of mechanical skid plateform, cause feed and to go back to the cutter gap large, shake cutter phenomenon is serious, and cutting stability is poor.
Summary of the invention
The purpose of this utility model provides mechanical skid plateform leading screw clearance adjustment mechanism in a kind of building-block machine, solve in the existing trapezoidal nut feed screw apparatus because of the clearance issues between nut and the leading screw, exist feed large with time cutter gap, shake cutter phenomenon is serious, the poor deficiency that waits of cutting stability, the utility model realizes that the gap between nut and the leading screw becomes capable of regulating by adjusting, so that the smooth running of mechanical skid plateform and improving its service life.
The purpose of this utility model is achieved through the following technical solutions, mechanical skid plateform leading screw clearance adjustment mechanism in a kind of building-block machine, comprise the leading screw that spins in trapezoidal nut and the trapezoidal nut, it is characterized in that, the adjusting nut that spins at smaller diameter end setting and the leading screw of trapezoidal nut, trapezoidal nut and adjusting nut connecting part arrange axial flat key groove, insert flat key in the flat key groove, flat key is nested with fixed cover outward, be nested with the pad of being close to fixed cover on the adjusting nut of fixed cover one end, the locking nut that spins on the adjusting nut in the pad outside, the seam that pad matches with setting on the adjusting nut.
Locking nut screw radially is set, screw in lock-screw in the screw, the termination of lock-screw tightly touches adjusting nut.
The utility model is by arranging the adjusting nut of the leading screw that spins equally at an end of trapezoidal nut, by being set, flat key is connected with fixed cover between adjusting nut and trapezoidal nut, by the position between locking nut and pad adjusting trapezoidal nut and adjusting nut, thereby make a splaying of former trapezoidal nut and threads of lead screw become threads of lead screw and trapezoidal nut, two ends backlass between adjusting nut, make leading screw become capable of regulating with the gap of trapezoidal nut by adjusting on the whole, so that the smooth running of mechanical skid plateform and improving its service life, the utility model is simple in structure, effect is remarkable, is conducive to improve the quality of products and service life.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure, 1 trapezoidal nut, 2 fixed covers, 3 flat keys, 4 pads, 5 locking nuts, 6 adjusting nuts, 7 leading screws, 8 lock-screws.
The specific embodiment
Further specify in conjunction with the accompanying drawings and embodiments the utility model, as shown in Figure 1, the utility model is by trapezoidal nut 1, fixed cover 2, and flat key 3, pad 4, locking nut 5, adjusting nut 6, leading screw 7 and lock-screw 8 consist of.Only have trapezoidal nut 1 and leading screw 7 in the former mechanical skid plateform nut screw device, the rotation of leading screw 7 passes to trapezoidal nut 1 moving linearly.The utility model is at the leading screw 7 of the trapezoidal nut 1 one ends adjusting nut 6 that spins, on adjusting nut 6 and the trapezoidal nut 1 the flat key groove is set, insert flat key 3 in the flat key groove, the flat key 3 outer fixed covers 2 that are nested with, be nested with the pad 4 of being close to fixed cover 2 on the adjusting nut 6 of fixed cover 2 one ends, on the locking nut 5 that spins on the adjusting nut 6 in pad 4 outsides, pad 4 and adjusting nut 6 seam that matches is set.Can only move axially between two nuts and can not mutually rotatablely move; Rotational lock nut 5, this moment, adjusting nut 6 can only move to the right, screws lock-screw 8 when moving to reasonable clearance locking nut 5 locking positionings are got final product; Again adjust after using a period of time gap to increase.
Claims (2)
