Abstract

The invention provides a lifting device based on a linear bearing, which belongs to the field of lead screw lifting devices and solves the problem of low fitting precision of guide pillars and guide sleeves of the lead screw lifting device in the prior art. The lifting device based on the linear bearing comprises a base plate, a motor, a lead screw, a lead screw nut and a carrying platform, further comprises a guide rail and a guide sleeve, wherein the motor is installed on the base plate; the lead screw is driven by the motor to rotate; the lead screw nut is sleeved on the lead screw; the carrying platform is fixed on the lead screw nut for holding articles to be lifted; the guide rail is installed at one side of the lead screw in parallel; the guide sleeve is sleeved on the guide rail; the guide sleeve is connected with the lead screw nut fixedly so as to move along the axial direction of the lead screw nut; and the guide rail and the guide sleeve form a sliding mechanism adopting the linear bearing. The lifting device has the advantages of high precision and transmission stability.

Description

technical field [0001] The invention belongs to the field of transmission, and relates to a lifting device using a screw rod, in particular to a lifting device based on a linear bearing. Background technique [0002] Screw drive is a very common way to change rotation into linear motion. Because of its stable transmission, small step feed and precise control, it is often used in various occasions that require high precision, such as Machine tools, CNC lathes, etc. In the lifting device, it can also be realized by screw drive. [0003] The traditional screw lifting device mainly uses the motor to drive the screw to rotate through the coupling, thereby driving the screw nut to move up and down, and the stage is fixed on the screw nut to move up and down together to realize the lifting. There are usually guide posts and guide sleeves on both sides of the screw to assist positioning and prevent angular deviation caused by the tilt of the screw. The conventional guide post is ...
