Lead screw nut mechanism

Abstract

The invention discloses a lead screw nut mechanism. The lead screw nut mechanism comprises a supporting plate, wherein fixed plates are fixedly connected to the two ends of one side of the supporting plate; a lead screw is fixedly connected between the opposite sides of the two fixed plates; a transmission mechanism is arranged on the outer surface of the lead screw; a lubricating mechanism and a clamping mechanism are arranged in the transmission mechanism; the transmission mechanism comprises a movable plate and a movable block; and one side of the movable plate is in sliding connection with the supporting plate through a sliding piece. The invention relates to the technical field of lead screw nuts. According to the lead screw nut mechanism, the transmission mechanism is arranged, a motor is used for driving a rotating shaft to rotate, and transmission of a first transmission wheel, transmission of a transmission belt and transmission of a second transmission wheel are matched, so that the lead screw rotates; and through sliding supporting of a sliding groove and a sliding block, the lead screw nut mechanism is prevented from completely bearing the weight of machining equipment in the using process, long-term use of the lead screw can be kept, and the moving distance of the machining equipment can be better and accurately adjusted.

Description

technical field [0001] The invention relates to the technical field of screw nuts, in particular to a screw nut mechanism. Background technique [0002] Using the principle of inclined plane, the inclined plane is curled and deformed to form ribs; the rotation is changed into translation; the screw rotates a circle, and the nut is displaced by one pitch; the sliding screw nut mechanism has simple structure, convenient processing, low manufacturing cost, and self-locking Function, but its frictional resistance torque is large and transmission efficiency is low. Although the structure of the ball screw nut mechanism is complicated, the manufacturing cost is high, and it cannot be self-locked, its biggest advantage is that the frictional resistance torque is small and the transmission efficiency is high (92% to 98%) , high precision, good system stiffness, reversible movement, long service life, so it has been widely used in mechatronic systems. [0003] The existing screw nut...
