Sliding table mechanism utilizing hydraulic cylinder and gear to realize double-speed movement

Abstract

The invention discloses a sliding table mechanism utilizing a hydraulic cylinder and a gear to realize double-speed movement. The sliding table mechanism comprises a controller, a sliding table body and a sliding table mechanism, wherein the sliding table mechanism comprises a sliding table seat, a linear guide rail, a driving gear, a driving oil cylinder, a sliding table body rack and a sliding table seat rack; the controller is arranged on the sliding table seat and used for controlling the driving oil cylinder to drive the driving gear to act; the linear guide rail is arranged on the sliding table seat; the sliding table body is arranged on the linear guide rail, and the sliding table body rack is arranged on the sliding table body; the sliding table seat rack is arranged on the sliding table seat; and the driving gear is simultaneously meshed with the sliding table body rack and the sliding table seat rack. The sliding table mechanism has the following beneficial effects that the structure is relatively simpler and is convenient to machine and mount, the manufacture cost is low, and the sliding table mechanism adopting the high-precision linear guide rail is high in transmission precision; and the sliding table mechanism having the advantages of large output force, high speed, stable running, high adapting capability, strong expanding capability and high performance-cost ratio is highly competitive on the market.

Description

technical field

[0001] The invention relates to a technology in the field of machinery, in particular to a sliding table mechanism that uses hydraulic cylinders and gears to move at double speed. Background technique

[0002] The mechanical sliding table is generally driven by a gear or a worm, and its speed is a fixed speed determined by a gearbox. It is characterized by a simple structure and is relatively easy to implement. The hydraulic sliding table is generally driven by a hydraulic cylinder, and its biggest feature can realize stepless speed change or single-way speed change, but its manufacturing cost is high.

[0003] 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 sliding tables in the prior art, especially hydraulic sliding tables and mechanical sliding tables, all have an oil cylinder of the sliding table, which can only control the moveme...
