The ball screw lubrication cooling device provided by this creation mainly includes: a screw (1), a nut (2), a majority of balls, ^ an oil mist supply system;彳 (1) has an external thread; the nut (2) is hollow, the nut (2) has a thread, and the nut (2) is provided with a circulation passage (21) and a plurality of through holes-(22), The circulation passage (21) is provided with an inlet end and an outlet end. The through hole (22)_ is disposed at a vertical contact point between the ball and the spiral track, and is connected to the circulation passage (21) and the nut (2). The internal oil thread supply system is connected to the inlet end and the outlet end of the nut. The system uses the venturi principle to atomize the lubricating oil into oil and gas, and has pressure adjustment control at the inlet end and the outlet end. By adjusting the positive and negative pressure of the controller to control the oil mist pressure in the circulation passage (21), the system can perform one-way or two-way output according to requirements, and can also control the oil and gas output by computer control pressure to continuously replenish the ball screw. (1) Lubricate and cool with the nut (2) and the ball. _ The embodiment of the present invention is mainly that the nut (2) is fitted on the outer side of the screw (1), the thread on the inner side of the nut (2) and the thread on the outer side of the screw (1) are matched with each other 'ball on the screw (1) The outer thread is rotated in a spiral path formed by the internal thread of the nut (2); the inlet end and the outlet end of the circulation passage (21) of the nut (2) are connected to the joint (26), and then the joint (26) Connected to the oil mist supply system, more than one through hole (22) in the circulation passage (21) is threaded through the internal thread of the nut (2), and the pressure adjustment controller in the oil mist supply system is controlled by positive pressure and 7 M323540 The oil pressure in the negative pressure control circulation passage (21) is used to adjust the lubrication of the oil and gas to the ball screw. When the oil and gas generated by the oil mist supply system is pressurized by the pressure controller, the oil and gas enters. After the circulation channel, the through hole (22) ^ enters the internal thread to make the ball adhere to the oil and gas to achieve the lubrication effect. To reduce the cost, the processing process is simplified, and the through hole (22) is directly processed from the outer diameter of the nut (2) to - crepe inside the nut (2), and in the outer diameter of the circulation passage (21) and the nut (2) Then - a hole plug (23), which aims to achieve its closed loop path (21) "Please see figure II _ map." Referring to FIG. 3 and FIG. 4 , in the second embodiment of the present invention, a sleeve (24) is disposed on the outer diameter of the nut (2), and the inner diameter of the sleeve (24) has a spiral groove and a screw width (2). Forming the far-pass % channel (21), the end face of the kit (24) is provided with a closing element, and the closing element is an end cap (26) and an oil seal (25), which are installed at the two ends of the kit (24) to prevent oil and gas leakage. IX", the inlet end and the outlet end connection joint (26) of the circulation passage (21) are connected to the oil mist supply system, and the end cover (26) is installed as shown in Fig. 5, according to the nut ( 2) The form is increased or decreased. The number of end caps (26). Please refer to FIG. 6 and FIG. 7 . In the third embodiment of the present invention, the nut ( 2 ) has a receiving groove ( 28 ) communicating with the through hole ( 22 ) for adjusting the component ( 3 ) In the setting, the adjusting element (3) is provided with a fine hole (31). Please refer to Figure 8 for the 'adjusting the piece (3). The whole group is replaced. The size of each group of holes (31) is different. (31) The inner diameter is less than or equal to the inner diameter of the through hole (22), and must be connected to each other. 'The size of the fine hole (31) on the adjusting element (3) controls the release of the oil and gas 8 M323540 "Please refer to the figure. Eight", nut (2) outer diameter setting kit (2 sentences, the end face of the kit (24) is provided with a closing element, the closing element is an end cover (26) and an oil seal (25), which is installed in the kit (24) To prevent oil and gas leakage, the oil mist supply system connection kit (24) nut (2) forms the circulation passage (21), and the pressure control system of the oil mist supply system sets the pressure to make the oil and gas enter the circulation path. (21) After penetrating the fine hole (31) of the adjusting element Ο), a small amount of lubricating oil gas is introduced into the screw (1) through the through hole (10) of the nut (2), and the ball and the spiral groove are lubricated. And can reduce the temperature of the nut.
