AI Technical Summary

Problems solved by technology

When this lifting device works, the lifting speed has a large impact and is not stable. When approaching the pallet, when lifting the pallet, and when the motion stops, the speed cannot be changed according to the ideal state, which affects the lifting and turning quality of the pallet.

Abstract

A 4-curve low-impact high-speed lifter for lifting the rotary supporting plate on machine-tool is composed of hydraulic cylinder, vertical slide way, slide body in said vertical slide way, a roller under said slide body and plate-type cam matched with said roller, arranged in the slide way on base and connected to the piston in hydraulic cylinder. Said plate-type cam has a working line consisting of two straight line segments, and 4 parabolic segments.

Description

Technical field: [0001] The invention relates to a lifting mechanism, in particular to a four-curve low-impact and high-speed lifting mechanism, which is mainly used for lifting a rotary pallet on a high-speed machining center machine tool in the machining industry. Background technique: [0002] When the existing high-speed machining center machine tool is machining the workpiece, the workpiece is fixed on a fixture, and the fixture is fixedly connected with the supporting plate arranged horizontally. The supporting plate bearing is supported on the bed and can be raised and lowered relative to the bed. , before the pallet is rotated by the driving device, the pallet needs to be lifted to a certain height. At present, the structure of the lifting device installed on the machining center has a vertical slideway. The sliding body, the piston rod on the hydraulic cylinder is connected to the sliding body, through the action of the oil cylinder, the sliding body is driven to mo...
