Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1: Please refer to Figures 1 to 5 In this embodiment, a thread greasing device for an EMU includes a workbench 13, the top surface of the workbench 13 is fixedly connected to a clamping plate 20, the top surface of the clamping plate 20 is fixedly connected to a fixing plate 19, an electric push rod 18 is fixedly installed on the front surface of the fixing plate 19, and a pressure device 8 is provided on the electric push rod 18.

[0027] The pressure-applying device 8 includes a movable plate 17, which is fixedly connected to the output end of the electric push rod 18.

Two limiting plates 27 are fixedly connected to the front of the clamping plate 20. Two driving rods 23 are rotatably connected between the two limiting plates 27 through a bearing.

The outer peripheral wall of the driving rod 23 at the back is fixedly covered with an active roller 9, and the outer peripheral wall of the driving rod 23 at the front is fixedly covered with a passive roller 11. The outer peripheral wall of the rotating rod 15 is fixedly covered with a pressure roller 10. A workpiece 1 is placed between the active roller 9 and the passive roller 11. The top surfaces of the two limiting plates 27 are provided with a clearance hole 22.

[0028] The workpiece 1 passes through two clearance holes 22 , which are semicircular holes. The pressure roller 10 fits the workpiece 1 , and the active roller 9 and the passive roller 11 both fit the workpiece 1 .

[0029] It should be noted that the electric push rod 18 is a conventional device known to the public in the prior art, and its specific structure and working principle will not be described in detail herein.

[0030] Specifically, the workpiece 1 is placed between the active roller 9 and the passive roller 11 and fits with them. The workpiece 1 passes through the clearance hole 22 and the electric push rod 18 is started. The output end of the electric push rod 18 drives the movable plate 17 to move, thereby making the pressure roller 10 fit with the workpiece 1, restricting the workpiece 1, and the active roller 9 rotates, driving the workpiece 1 to rotate.

[0031] Example 2: Please refer to Figures 1 to 5 In this embodiment, based on the first embodiment, a driving assembly is provided on the workbench 13, and the driving assembly includes a fixing frame 24, which is fixedly connected to the top surface of the workbench 13. A power motor 6 is fixedly installed on the right inner wall of the fixing frame 24, and the output end of the power motor 6 passes through the fixing frame 24 and extends to its right side. A driving gear 25 is fixedly installed on the output end of the power motor 6, and a driven gear 21 is fixedly installed on the outer peripheral wall of the driving rod 23 located on the back, and a transmission belt 7 is installed between the driving gear 25 and the driven gear 21.

[0033] Specifically, the power motor 6 is started, and the output end of the power motor 6 drives the driving gear 25 to rotate, and through the action of the transmission belt 7, drives the driven gear 21 to rotate, and then the driving roller 9 rotates, driving the workpiece 1 to rotate.

The pneumatic glue injection pump 12 adopts a pneumatic pump that can store a large amount of coating materials at one time, and uses compressed air to ensure constant pressure and quantitative supply of materials to the glue gun 2, so that the glue gun 2 can inject grease evenly and continuously.

[0037] Specifically, the workpiece 1 passes through the clearance hole 22 and fits with the equidistant nut 5, the workpiece 1 rotates, and the pneumatic glue pump 12 is started, so that the grease enters the interior of the glue gun 2, and the grease passes through the glue outlet and falls on the outer surface of the workpiece 1. Then, through the threaded connection between the workpiece 1 and the equidistant nut 5 and the restriction of the glue gun guide rail 5 on the glue gun fixing plate 3, the glue gun fixing plate 3 drives the glue gun 2 to move, and the workpiece 1 is greased.

[0038] The working principle of the above embodiment is:

The output end of the power motor 6 drives the active gear 25 to rotate, and under the action of the transmission belt 7, drives the driven gear 21 to rotate, thereby making the active roller 9 rotate, driving the workpiece 1 to rotate, and starting the pneumatic glue pump 12, thereby allowing grease to enter the interior of the glue gun 2, and the grease passes through the glue outlet and falls on the outer surface of the workpiece 1, and then through the threaded connection between the workpiece 1 and the equidistant nut 5 and the restriction of the glue gun guide rail 5 on the glue gun fixing plate 3, the glue gun fixing plate 3 drives the glue gun 2 to move, and the workpiece 1 is greased.
