Utility model content
The problem existing for prior art, the utility model provides a kind of hollow oil cooling transmission system simple in structure.This system is effectively avoided ball screw to produce thermal change position and is affected the positioning precision of lathe, stable, of fine qualities, the easy processing of this systematic function, simple to operate, easy to maintenance.
For achieving the above object, technical solutions of the utility model are:
Hollow oil cooling transmission system, this system comprises that one is fixed on the ball screw on support, and described ball screw is that one end is blind end, and the other end is the hollow structure of opening end; Described opening end is communicated with the feeder of a hollow oil cooler, and this feeder is communicated with a unloading port; One cooling tube is suspended in the hollow bulb of described ball screw, and one end of this cooling tube is communicated with an oil-in, and the other end is openend, and the setting at regular intervals of the hollow bulb of this openend and ball screw bottom tool.
Further, in the junction of described ball screw and hollow oil cooler, be provided with oil-recovery tank, one end of this oil-recovery tank was communicated with an oil return inflatable mouth, and the other end is communicated with an oil return outlet.
Further, described oil return outlet is communicated with the fuel tank of an oil cooling machine.
Further, described oil-in is communicated with the fuel tank of an oil cooling machine, and the fuel tank of this oil cooling machine is communicated with the feeder of hollow oil cooler.
The utility model, according to the original design of lathe, is changed ball screw, with the ball screw of hollow structure, replaces traditional ball screw, need reserve the fixed position of hollow oil cooler in the end section of hollow ball screw.Be suspended at the cooling tube of ball screw hollow bulb, between the inwall of cooling tube and ball screw hollow bulb, form cold oil passage, so that pump into the cold oil of oil-in, after cooling tube, along the cold oil passage between cooling tube and ball screw hollow bulb inwall, flow to the feeder of hollow oil cooler, recycling the fuel tank that pressure that the oil pump of an oil cooling machine produces pushes back oil cooling machine cold oil is lowered the temperature, through oil-in, send cooling tube Reusability back to again, form the closed circuit of a cold oil.The oil-recovery tank that the utility model is provided with, can further reclaim the cold oil oozing out from ball screw and hollow oil cooler junction, and be exported and recycled by oil return.Adopt the hollow oil cooling transmission system of above-mentioned technical pattern, when work in-process scheming bed is made high-speed motion, hot temperature liter that friction between the steel ball in reason ball screw and groove or steel ball and steel ball does not produce, has effectively avoided ball screw to produce thermal change position and has affected the positioning precision of lathe.Stable, of fine qualities, the easy processing of this systematic function, simple to operate, easy to maintenance.
