BALL SCREW LUBRICATION DEVICE FOR CNC GRINDING MACHINE

摘要

The present invention relates to a ball screw lubrication device for a CNC grinding machine, in order to simplify the structure of the lubrication pipe and raise the cause of failure, the wheel body (1) above the slide part of the saddle (2) where the lubrication pipe is installed on one side. ) Is movable so that the ball screw (3) is rotatably driven inside the whetstone body, the lubrication pipe (11) is connected to the ball screw, the pipe pipe is a slide portion The orifice 8 is fastened to the flow path of the whetstone body 1 connected to the flow path of the ball screw 3 by the pipe tie 12 in the middle part of the pipe pipe for lubrication. The elbow 10 is connected to the orifice by a connector 9, and the elbow is configured to communicate with the pipe pipe 11 to lubricate the slide surface between the grindstone body 1 and the saddle 2. Oil supplied to In the middle of the pipe pipe 11 is separated by the pipe tie 12 so that a part of it is transferred to the ball screw 3, and is assembled to the grindstone body 1 through the elbow 10 and the connector 9. Ball screw lubrication device for a CNC grinding machine to pass through the orifice (8), which is a fine conduit, to be supplied to the frictional contact portion of the ball screw (3) and the ball screw nut (4) from the ball nut housing (5).
