They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] A protective structure for a machine tool, such as Figure 1 As shown, it includes a frame base 1, a workbench 2 is provided on the base, and a debris collection trough 16 is provided on the frame base 1 below the workbench 2. The debris generated by the workpiece processed on the workbench 2 will splash or fall into the debris collection trough 16, which is convenient for cleaning after the processing is completed; a shielding and protective mechanism 3 is provided on the frame base 1, and the workbench 2 is provided on the shielding and protective mechanism 3. Some debris will fall directly from the front and back sides of the workbench 2 directly into the debris collection trough 16, and some debris will first fall from the left and right sides of the workbench 2 onto the shielding and protective mechanism 3, and then be guided by the shielding and protective mechanism 3 and finally fall into the debris collection trough 16; the frame base 1 is provided with inclined guide plates 17 for guiding debris on both sides of the shielding and protective mechanism 3. The inclined guide plates 17 can guide the debris into the debris collection trough 16, which further facilitates cleaning and avoids the generation of cleaning dead corners.

[0023] like Figure 1 、 Figure 2 As shown, the shielding and protection mechanism 3 includes a guide frame 4 and a side block assembly 5, and the side block assembly 5 is arranged in the guide frame 4, the workbench 2 is slidably sleeved on the guide frame 4, the side block assembly 5 is connected to the workbench 2, and blocks the gap formed on the side of the guide frame 4, so that a relatively tight seal is formed between the outer side of the shielding and protection mechanism 3 and the workbench 2, and the debris generated by the workpiece processing is not easy to enter the shielding and protection mechanism 3; a moving assembly 13 is provided at the bottom of the workbench 2, and the moving assembly 13 is located inside the guide frame 4, so the shielding and protection mechanism 3 can form a shielding protection for the moving assembly 13 to prevent debris from splashing into the moving assembly 13 and prevent the moving assembly 13 from getting stuck or damaged.

[0024] like Figure 3As shown, the guide frame 4 includes a bottom frame 6, a side sealing plate 7 and a guide top cover 8, wherein the bottom frame 6 is a rectangular frame and is fixed to the base of the frame base 1, the guide top cover 8 is a pointed top plate, and its bottom two sides are fixed to the bottom frame 6, and the side sealing plate 7 is fixed to the guide top cover 8 and the bottom frame 6, and is arranged on both sides of the guide top cover 8; Figure 5 As shown, the workbench 2 is provided with a through slot 9 that matches the diversion top cover 8, so that the workbench 2 can move between the two side sealing plates 7, and the part of the workbench 2 below the through slot 9 will be blocked in the diversion shell frame 4.

[0025] like Figure 4 As shown, the side baffle assembly 5 includes two groups of guide strips 10, side protective plates 11 and accordion covers 12, wherein the two guide strips 10 are respectively fixed on the two long sides of the bottom frame 6, and the side protective plates 11 are fixed to the front and rear sides of the workbench 2, and the fixed position is located below the through slot 9, and the two ends of the accordion cover 12 are respectively fixed to the side protective plates 11 and the side sealing plates 7, and the heights of the accordion cover 12 and the side protective plates 11 are equal to the distance between the bottom frame 6 and the guide top cover 8. Therefore, the accordion cover 12 and the side protective plates 11 will block and fill the side gaps of the guide frame 4, so that the shielding and protection mechanism 3 forms a more tight seal on the workbench 2; the top end of the accordion cover 12 is in contact with the guide top cover 8, and the bottom end of the accordion cover 12 is in contact with the guide strips 10, thereby further increasing the sealing effect and guiding the contraction and stretching of the accordion cover 12.

[0026] like Figure 2 、 Figure 5 As shown, the moving assembly 13 includes a slide rail 14 and a slide sleeve 15. The slide sleeve 15 is slidably mounted on the slide rail 14. The slide rail 14 is fixed on the frame base 1. The slide sleeve 15 is fixed to the bottom of the workbench 2. The workbench 2 can be moved by cooperating between the slide rail 14 and the slide sleeve 15. When the workbench 2 moves, the accordion covers 12 on both sides will extend and contract, thereby ensuring that the sides of the guide frame 4 are covered and shielded.

[0027] like Figure 5 As shown, scraper baffles 18 are fixedly provided on both sides of the workbench 2, and the scraper baffles 18 are fitted with the guide top cover 8. After the processing is completed, the workbench 2 is moved back and forth, and the scraper baffles 18 will scrape off the debris remaining on the guide top cover 8, which is convenient for subsequent cleaning.
