Hydraulic system for shifting gears and changing speeds of headstock sliding gears

Abstract

The invention discloses a hydraulic system for shifting gears and changing speeds of headstock sliding gears and belongs to the technical field of headstocks. The hydraulic system comprises a headstock and a gear hydraulic cylinder driving box, wherein the gear hydraulic cylinder driving box is mounted on the inner side of the end of the headstock; an inner cavity is formed in the headstock; and afixing plate is fixedly connected to the inside of the inner cavity; a first rotating shaft is inserted into the fixing plate; and a sliding gear is connected to a position, located on one side of the fixing plate, of the exterior of the first rotating shaft. According to the hydraulic system, a traditional hydraulic control overflow valve, a throttling valve and a hydraulic control one-way valveare not used, the hydraulic system and a lubricating system of the headstock are integrated as a whole; the hydraulic cylinder can move forwards and backwards by only needing two two-position four-way electromagnetic reversing valves; the control method is safe and reliable; hydraulic control gear reversing can be achieved; gears and bearings in the headstock can be lubricated; the manufacturingcost is reduced; and the hydraulic system is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of bedside boxes, in particular to a hydraulic system for shifting gears by sliding gears of the bedside box. Background technique [0002] At present, the existing technologies are CNC lathes, CNC milling machines, vertical machining centers and other machine tools. In order to obtain the main transmission system with high torque and wide speed, there are often one or two pairs of double-sliding gears in the box, which are driven by hydraulic cylinders. Gear shifting and shifting, therefore, require a dedicated set of hydraulic station controls. [0003] The existing CNC machine tool bedside box is driven by a hydraulic cylinder to change gears. It is widely used in the market and various enterprises. It has been used for more than 30 years and has formed a frame. The designer believes that there is no need to modify it, and it is impossible to modify it. Various machine tool manufacturers are still using ...

Problems solved by technology

[0003] The existing CNC machine tool bedside box is driven by a hydraulic cylinder to change gears. It is widely used in the market and various enterprises. It has been used for more than 30 years and has formed a frame. The designer believes that there is no need to modify it, and it is impossible to modify it. Various machine tool manufacturers are still using this old idea and old structure to produce machine tools, which restricts the development requirements for the conversion of new and old kinetic energy, and has fallen behind the times. Therefore, technological innovations have been carried out and a new design idea has been proposed.
