[0018] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0019] Depend on Figures 1 to 5 Provided is a uniform oiling device for the inner wall of a valve workpiece, comprising a base 1, a driving structure arranged on one side of the base 1, an oiling structure arranged on the other side of the base 1, and a connecting component for connecting the driving structure and the oiling structure, wherein the driving structure drives and controls the oiling structure via the connecting component.

[0020] A lifting mechanism 16 is provided on one side of the base 1, and the lifting mechanism 16 moves the base 1 and the driving structure and the oiling structure thereon up and down, so as to cause the oiling structure to approach the inner wall of the component to be oiled. The lifting mechanism 16 is a prior art, and generally adopts a hydraulic cylinder or a pneumatic cylinder, and the base 1 is fixedly connected to the output shaft of the hydraulic cylinder or the pneumatic cylinder.

[0021] The connecting assembly includes a driving pulley 8 used in conjunction with the driving structure, and an auxiliary pulley 10 connected to the driving pulley 8 via a belt 9. The auxiliary pulley 10 is fixedly connected to the shaft sleeve 2. The driving structure drives the driving pulley 8 to rotate, and the driving pulley 8 drives the auxiliary pulley 10 to rotate via the belt 9.

[0022] The driving structure includes a ball screw 11 rotatably connected to the base 1, the ball screw 11 is fixedly connected to the driving pulley 8, and the driving structure also includes a ball screw nut 12 which is sleeved on the ball screw 11 and threadedly connected to the ball screw 11. The ball screw 11 and the ball screw nut 12 are connected by a ball screw. Under the action of the ball screw, the ball screw nut 12 can slide better along the ball screw 11.

[0023] The ball screw nut 12 is slidably connected to the base 1 , and the driving structure also includes a cylinder 13 for driving the ball screw nut 12 . The ball screw nut 12 is guided under the action of the base 1 , and is driven under the action of the cylinder 13 .

[0024] The oiling structure comprises a sleeve 2 rotatably connected to a base 1, a rotating hole for accommodating the sleeve 2 is provided on the base 1, a step layer of a certain height is provided in the rotating hole, the sleeve 2 is located in the rotating hole and a support block used in conjunction with the step layer is provided on the outside, and the support block supports the sleeve 2 during the rotation of the sleeve 2;

[0025] An eccentric placement groove 3 is provided inside the shaft sleeve 2, and an oil filling valve is inserted into the placement groove 3 and rotates relative to the shaft sleeve 2. The lower end of the oil filling valve extends out of the shaft sleeve 2 for contacting the inner wall to be oiled. Since the placement groove 3 is eccentrically arranged and the oil filling valve is placed in the placement groove 3, when the shaft sleeve 2 rotates, the shaft sleeve 2 drives the oil filling valve to rotate, so that the movement trajectory of the oil filling valve is eccentric relative to the shaft sleeve 2, so that it can better contact the inner wall of the metal part to be oiled.

[0026] A needle bearing 14 is concentrically arranged in the placement groove 3, and the inner wall of the needle bearing 14 is used in conjunction with the valve body 4 through the bushing 15. The needle bearing 14 supports the valve body 4 on the one hand, and provides relative rotation assistance for the valve body 4 on the other hand. The arrangement of the needle bearing 14 and the bushing 15 facilitates the limiting and fixing of the oil filling valve.

[0027] The oil filling valve includes a valve body 4, an oil filling head 5 which is threadedly connected to the outlet of the valve body 4 and communicated with the valve body 4, an oil passage 6 which is communicated with the valve body 4 is formed in the oil filling head 5, and a plurality of oil outlet holes 7 which are communicated with the oil passage 6 are formed on the side wall of the oil filling head 5. Under the action of gravity, the lubricating oil in the valve body 4 enters the oil filling head 5. At the same time, the provision of the plurality of oil outlet holes 7 facilitates the outflow of the lubricating oil in multiple directions, further ensuring that the lubricating oil can be evenly applied to the inner wall of the metal tube.

[0028] When the utility model is used, the staff assembles each structure to a suitable position, and places the metal valve workpiece to be oiled directly below the oil filling valve, and the oil filling head 5 is inserted into the opening of the workpiece to be oiled under the action of the lifting mechanism 16, and inserted to a suitable height;

[0029] After the oiling head 5 is inserted into the opening of the workpiece to be coated, the cylinder 13 drives the ball screw nut 12 to move downward. Since the ball screw nut 12 is slidably connected to the base 1, the ball screw nut 12 does not rotate during the movement. During the downward movement of the ball screw nut 12, due to the threaded connection between the ball screw 11 and the ball screw nut 12, the ball screw nut 12 drives the ball screw 11 to rotate.

[0030] While the ball screw 11 is rotating, the ball screw 11 drives the auxiliary pulley 10 to rotate via the active pulley 8 and the belt 9. Under the eccentricity of the placement groove 3, the oiling head 5 rotates along the inner wall of the workpiece to be coated, thereby achieving uniform coating of the inner wall of the workpiece to be coated.

[0031] The utility model utilizes an eccentrically arranged placement groove to realize eccentric rotation of the oil filling valve, so that during the rotation of the oil filling valve, the oil filling head is always in contact with the inner wall of the workpiece to be oiled, simulating the manual action of oiling the inner wall of the workpiece to be oiled, and utilizing the precision of the machinery to ensure that the inner wall of the workpiece to be oiled can be evenly oiled each time, thereby ensuring the reproducibility of the even oiling action.
