The invention belongs to the technical field of electric push rods, and particularly relates to a high-precision push rod. The high-precision push rod comprises a sleeve, a pushing member, a screw rodand a driving mechanism. The pushing member comprises an inner movable seat, an outer movable seat and a plurality of connecting rods, and the inner end of each connecting rod is fixedly connected with the inner movable seat, the outer end of each connecting rod penetrates through the outer end of the sleeve and is connected with the outer movable seat, and the driving mechanism is connected withthe inner end of the screw rod; and an elastic limiting component is also arranged in the sleeve and comprises an elastic member, a cover plate, a pressure ring and a limit bearing, the elastic member is annularly arranged on the screw rod, one end of the elastic member abuts against the inner end of the sleeve, the cover plate is annularly arranged on the screw rod and abuts against the other end of the elastic member, the middle of the cover plate is provided with a through hole for the screw rod to pass through, the limit bearing is rotatably arranged at the inner end of the screw rod in asleeving manner, the pressure ring is annularly arranged on the screw rod, and the two ends of the pressure ring abut against the limit bearing and the cover plate. The elastic member is lengthened to enable the cover plate, the pressure ring and the limit bearing to move towards the outer end of the sleeve, the screw rod is further pressed, and the accurate mounting precision of the screw rod iskept.
Description
technical field [0001] The invention belongs to the technical field of electric push rods, in particular to a high-precision push rod. Background technique [0002] Chinese invention patent (publication number is CN104930148A) provides a kind of electric push rod device. The electric push rod device uses the first push part to be screwed to the screw rod, and a plurality of connecting rods passing through the second fixed part are fixedly connected between the first push part and the second push part, so that when the screw rod rotates, it drives The first pushing part moves back and forth along the axial direction of the screw rod. In this electric push rod, the two ends of the screw rod are rotationally connected with the first bearing and the second bearing, and the first bearing and the second bearing are respectively fixed on the first fixing part and the second fixing part, which will easily lead to Bearings and screw rods are worn, which reduces the installation acc...
