Novel guide rail rigid-flexible coupling platform

Abstract

The invention provides a novel guide rail rigid-flexible coupling platform. The novel guide rail rigid-flexible coupling platform comprises a base, guide rails mounted on the base, sliding blocks arranged on the guide rails in a sliding mode, a rigid-flexible coupling platform fixedly arranged on the sliding blocks, a driving unit used for driving the rigid-flexible coupling platform to slide anddetection units used for detecting speed and displacement of the rigid-flexible coupling platform; each guide rail comprises a guide rail body and a bolt; each guide rail body comprises a first surface, a second surface, a third surface and a fourth surface; the first surfaces face to the sliding blocks; the second surfaces and the third surfaces are adjacent to the first surfaces; lug bosses arearranged at positions, away from the base, of the second surfaces and the third surfaces and are used for mounting rolling parts in the sliding blocks; the fourth surfaces are opposite to the first surfaces and are in contact with the base; through holes penetrating through the first surfaces and the fourth surfaces are formed in the guide rail bodies; the bolts are used for fixing the guide railbodies on the base through the through holes; and pore-free connection is formed between the bolts and the through holes.

Description

technical field [0001] The invention belongs to the technical field of rigid-flexible coupling motion platforms, and in particular relates to a rigid-flexible coupling platform adopting a new type of mechanical guide rail. Background technique [0002] The motion platform is the core component of mechanical equipment, such as inkjet printers, laser scribing machines, etc. Due to its high acceleration performance, the mechanical guide rail type motion platform is widely used in industrial equipment such as electronic manufacturing, laser processing, precision testing, and inkjet printing. The motion platform can be roughly divided into rigid platform and rigid-flexible coupling platform. The rigid-flexible coupling platform uses the elastic deformation of the flexible hinge to compensate for frictional death, which can improve the accuracy of the motion platform. [0003] At low speed, the precision of the mechanical rigid-flexible coupling platform can basically meet the re...

AI Technical Summary

Problems solved by technology

However, as the speed increases, the mechanical rigid-flexible coupling platform will cause speed fluctuations due to the existence of gaps between the guide rail and the slider sliding on the guide rail, which will affect the accuracy of the platform.
