Bearing direction manual loading mechanism and loading method for rolling linear guide rail pair

Abstract

The invention discloses a bearing direction manual loading mechanism and a loading method for a rolling linear guide rail pair. The bearing direction manual loading mechanism comprises a hand wheel assembly, a loading assembly and a measurement assembly, and is characterized in that torque is transmitted between the hand wheel assembly and the loading assembly through bayonet matching; during loading, an operator rotates the hand wheel manually; small torque is transmitted to the loading assembly through a speed reducer in the hand wheel assembly; a loading main shaft in the loading assembly is transmitted to a trapezoidal lead screw nut block in a threaded transmission way through a trapezoidal lead screw; the nut block and a nut block flange move horizontally in a box body under the restraining actions of guide limiting screws arranged on the periphery of the box body; the nut block is used for compressing a disc spring in horizontal movement to generate spring force which is applied to the loading main shaft in order that the loading main shaft moves horizontally to drive the measurement assembly to realize load output; after the load output displayed on a sensor meets the requirement, the hand wheel is removed. Stable, continuous and large-load output (6t) can be realized through pure manual operation, the structure is compact and light, the reliability is high, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of loading mechanisms, in particular to a rolling linear guide rail sub-loading manual loading mechanism and a loading method. Background technique [0002] The rolling linear guide pair is a mechanical component composed of linear guides, rolling elements (balls or rollers), sliders, etc. It is widely used as a guide bearing part in the industrial field, with high positioning accuracy, small dynamic and static friction coefficients, and good maintainability. And other advantages, can reduce drive power consumption while ensuring running accuracy, has become a key functional component in industries such as CNC machining equipment, linear motion platforms, aerospace and industrial robots. In order to test the reliability, static stiffness, life and other indicators of the rolling linear guide pair, it is necessary to provide a large load in the bearing direction of the rolling linear guide pair. The existing...

Problems solved by technology

However, the loading mechanism encapsulates the necessary components such as reducer, servo motor, gear set, etc., so that the volume and mass of the entire loading mechanism are large; and the strong electricity during the working process of the servo motor may interfere with the reading of the force sensor value; these problems All will have an impact on the test work of the rolling linear guideway pair test platform driven by a small thrust linear motor
