Sliding table structure capable of moving at quadruple speed

Abstract

The invention discloses a sliding table structure capable of moving at a quadruple speed. The sliding table structure capable of moving at the quadruple speed comprises a sliding table body, driving blocks, a sliding table base, linear guide rails, a driving oil cylinder, a left pulley block unit and a right pulley block unit; the driving oil cylinder is a left and right two-way output hydraulic oil cylinder; the sliding table body is arranged on the linear guide rails; the driving blocks are fixed to the sliding table body, and the two ends of each driving block are each provided with a pulling cable; each pulley block unit is a quadruple moment wire winding method pulley block unit; the two ends of each pulling cable are connected to a fixed pulley block and the corresponding driving block; and the left pulley block unit and the right pulley block unit are symmetrical. The transmission principle of a pulley block mechanism is adopted for the sliding table structure capable of moving at the quadruple speed, the driving oil cylinder drives movable pulleys in pulley blocks to walk by L at the speed of V, after the strokes of four strands of steel wire ropes are gathered and superposed through fixed pulleys, the driving blocks are driven to walk by 4L at the speed of 4V, and quadruple amplification of the speed and the stroke is achieved; and the length of the oil cylinder can be shrunk by 3 / 4, the piston feeding speed is decreased by 3 / 4, process parameters of the driving oil cylinder are decreased, and cost is saved.

Description

technical field [0001] The invention relates to a technique in the field of machinery, in particular to a sliding table structure capable of quadruple-speed movement. Background technique [0002] According to the forecast and investment analysis report of China's sliding table industry from 2014 to 2020, the consumption of domestic mechanical sliding tables is currently on the rise year by year, and higher requirements are put forward for sliding tables: longer strokes and greater output force, higher automation control. [0003] Conventional mechanical slides are the main bed of combined machine tools, counter milling machines, and other special machine tools. The working principle of the mechanical slide table is that the slide plate moves longitudinally on the bed, because of the screw drive and the role of the gearbox. Various running speeds such as fast and slow can be obtained. [0004] Mechanical sliding table The use and performance of the mechanical sliding tabl...
