[0002] In the prior art, such as Figure 1 As shown, the structure of the internal protective telescopic shield of the machine tool is regular. The internal protective telescopic shield is connected to the moving column and expands and contracts as the moving column moves back and forth. However, due to the limitation of the internal structure of the machine tool, the chip falling slope is relatively gentle, which makes it easy for chips to fall and accumulate on the shield, and it is difficult for chips to slide naturally into the screw groove. When the machine tool is used for a long time, the debris accumulates to form chip clusters, which cannot guarantee the sustainability of the machine tool processing and reduces the stability of the machine tool use. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, one of the purposes of the utility model is to provide an internal protective chip removal structure that avoids chip accumulation and chip agglomeration during machining, thereby ensuring the sustainability of machine tool machining and improving the stability of machine tool use.

[0026] Figure 2-Figure 5 The utility model discloses an internal protection chip removal structure, which comprises an internal protection telescopic shield 10 , a movable column 20 , a bed 30 , a scraper plate 40 and a base 50 .

[0027] In this embodiment:

[0028] The inner protective telescopic shield 10 is arranged at the bottom of the moving column 20, one side of the inner protective telescopic shield 10 is connected to the moving column 20, and the other side of the inner protective telescopic shield 10 is provided with a chip drop opening 11. Therefore, the present application changes the regular structural design to a special-shaped design, so that the chips can fall into the screw row groove 31 below through the chip drop opening 11. In this embodiment, the cross-sectional shape of the chip drop opening 11 is rectangular. The chip drop opening 11 is directly opposite to the screw row groove 31.

[0029] The bed 30 is located on one side of the moving column 20, and is provided with a screw row groove 31, and the chip drop opening 11 is connected to the screw row groove 31. In this embodiment, the bed 30 is provided with the screw row groove 31 along its length direction, and the length direction of the screw row groove 31 is perpendicular to the moving direction of the moving column 20.

[0030] The scraper plate 40 is arranged at the bottom of the moving column 20 and is located above the inner protective telescopic shield 10. The moving column 20 moves forward and backward in one direction to make the inner protective telescopic shield 10 telescope. The moving column 20 drives the scraper plate 40 to move, so that the fallen chips on the inner protective telescopic shield 10 are pushed and scraped into the screw row groove 31 through the chip removal opening 11. Therefore, the fallen chips on the surface of the inner protective telescopic shield 10 can be automatically cleaned by the scraper plate 40 in a timely and effective manner, and will not cause the shield itself to be squeezed and damaged. In addition, with the continuous rotation of the screw row in the screw row groove 31, the fallen chips can be discharged from the inside of the machine tool, thereby avoiding the risk of screw row blockage and motor burning, and ensuring the stability and sustainable use of the machine tool. In this embodiment, the scraper plate 40 is installed obliquely on the moving column 20 and faces the chip removal opening 11, and an obtuse angle is formed between the scraper plate 40 and the moving column 20.

[0031] The base 50 is located at one side of the bed 30 and is fixedly connected to the bed 30, and the movable column 20 is movably mounted on the base 50. In this embodiment, the bed 30 and the base 50 are integrally formed. The length direction of the bed 30 is perpendicular to the length direction of the base 50.

[0032] In the present application, the inner protective telescopic shield 10 is provided with a special-shaped structure with a chip removal opening 11, and the scraping plate 40 is used to push and scrape the cuttings on the surface of the inner protective telescopic shield 10 through the chip removal opening 11 to the screw row groove 31 below. With the continuous rotation of the screw row in the screw row groove 31, the falling chips can be discharged from the inside of the machine tool. The present application can avoid the problem of chip accumulation and chip clusters during the processing, will not cause extrusion damage to the inner protective telescopic shield 10, and also avoids the risk of screw row blockage and motor burning, thereby ensuring the stability and sustainable use of the machine tool.

[0033] The present application also relates to a machine tool comprising the above-mentioned internal protection and chip removal structure.

[0034] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, several modifications and improvements can be made, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the utility model, and all of them belong to the protection scope of the utility model.
