[0041] Working principle: During use, the product to be processed is placed in the positioning seat 6. The Y-axis linear module 10 and X-axis linear module 11 drive the X-axis slide rail 30 and the worktable 5 to their respective positions. The Z-axis linear module 31 drives the riveting machine 9 to its corresponding position. The riveting machine 9 performs riveting operations on a certain position on the product. After the riveting operation at that position is completed, the Y-axis linear module 10, X-axis linear module 11, and Z-axis linear module 31 move to the next corresponding position, and the riveting machine 9 performs riveting operations on that position on the product again, thus completing the riveting operation of the processed product. When the riveting operation of the processed product is completed, the drive motor 23 drives the rotating rod 24 and the cam 25 to rotate, thereby pushing the top plate 26. The ejector rod 27 moves, which in turn compresses the spring 28 until the processed product is ejected for easy handling by the staff. When the Y-axis slide rail 29, X-axis slide rail 30 and Z-axis slide rail 8 need to be lubricated, the lubrication motor 20 drives the rotating shaft 19 and cam 18 to rotate, which in turn drives the assembly block 17 and the moving plate 15 to move back and forth inside the thin shell 14. The lubricating oil in the lubrication tank 13 is then transported to the thin shell 14 under the action of the one-way valve 22. From the thin shell 14, the lubricating oil is then transported through the lubrication pipe 12 under the control of the one-way valve 21 to the Y-axis slide rail 29, X-axis slide rail 30 and Z-axis slide rail 8 to lubricate them, thereby reducing friction, reducing wear and extending the service life of the guide rails.
