Abstract

The invention relates to the technical field of lead screw nut transmission, in particular to a high-precision lead screw nut transmission positioning device. The device comprises a fixing frame, a driving assembly, a transmission assembly and a load assembly, the driving assembly is installed on the fixing frame, the driving assembly drives the transmission assembly to work and drives the load assembly to move, and the transmission assembly comprises a transmission shaft, a driving bevel gear, a driven bevel gear, a first bearing seat, a second bearing seat, a lead screw and a nut. Two output ends of the driving assembly are connected with the transmission shaft, the transmission shaft is rotatably mounted on the fixing frame through the first bearing seat, the driving bevel gear is arranged at the end part of the transmission shaft, and the lead screw is rotatably mounted on the fixing frame through the first bearing seat. The problems that in the transmission process of the lead screw nut, due to the fact that the positioning accuracy is low after the lead screw nut stops and the lead screw nut has gaps, the positioning error is large, and some high-accuracy positioning transmission occasions cannot be applied are solved.

Description

technical field [0001] The invention relates to the technical field of screw nut transmission, in particular to a high-precision screw nut transmission positioning device. Background technique [0002] The lifting screw nut transmission mechanism converts rotary motion into linear motion. It is the most commonly used transmission element in tool machinery and precision machinery. It has the characteristics of high precision, reversibility and high efficiency. Through the work of the lifting lead screw nut transmission mechanism, the load parts loaded on it can be driven to perform lifting operation. [0003] However, in the prior art, during the transmission process of the screw nut, due to the low positioning accuracy after stopping and the gap between the screw nut itself, the positioning error is relatively large, and some high-precision positioning transmission occasions are not applicable, so there is an urgent need for research and development. High-precision screw nu...
