[0002] A high-end horizontal milling and turning machining center is a type of composite machine tool. Multiple functional components are installed inside the same machine tool. Each functional component has complex functions and actions. This results in the need to install a large number of water, electricity, gas, oil and other pipelines inside the machine tool to connect to the above functional components via cable chains.

Detailed Implementation

[0027] The specific embodiments of the present invention will be described below with reference to the accompanying drawings: Figures 1 to 10 As shown, a concealed flexible cable chain protection system includes a slide support block 2 fixedly connected to a machine tool frame 1. An inclined groove 3 is provided at the top edge of the slide support block 2. n protective plate sliders 4 are slidably connected within the inclined groove 3. The protective plate sliders 4 are connected to protective plates 6 via connecting blocks 5. Above the protective plate sliders 4, an outer pressure block 7 fixedly connected to the machine tool frame 1 is provided. An outer upper slide rail is formed between the bottom edge of the outer pressure block 7 and the machine tool frame 1. A groove is provided within the connecting block 5, and an upper top block 8 is provided within the groove. A dustproof spring 9 is connected to the bottom end of the upper top block 8, and a dustproof slider 10 is provided at the bottom end of the dustproof spring 9. The bottom end of the dustproof slider 10 presses against the gap between the protective plate sliders 4 and the connecting block 5.

[0028] The outer pressure block 7 is located outside the machining area on the machine tool frame 1. A support plate 11 is installed on the machine tool frame 1 within the machining area. The support plate 11 has a through hole, through which a top post 12 is movably connected. The front end of the top post 12 has a top post end 13. A spring 14 is sleeved on the top post 12, located between the support plate 11 and the top post end 13. The end of the top post end 13 contacts the inner pressure block 15. The bottom edge of the inner pressure block 15 also forms an inner upper slide rail with the machine tool frame 1. The inner upper slide rail is coaxial with and communicates with the outer upper slide rail. The upper edge of the protective plate slider 4 is slidably connected within the inner and outer upper slide rails.

[0029] The n protective plates 6 are sequentially labeled as No. 1, No. 2, ..., No. n. Each protective plate 6 has a U-shaped groove 16 at its bottom. A first guide strip 17 is provided at the bottom of the machine tool frame 1. The U-shaped groove 16 on protective plate No. 1 is slidably connected to the first guide strip 17, which is fixedly connected to the bottom of the machine tool frame 1. The U-shaped groove 16 on protective plate No. 2 is slidably connected to the outer side of the U-shaped groove 16 on protective plate No. 1, and so on. The U-shaped groove 16 on protective plate No. n is slidably connected to the outer side of the U-shaped groove 16 on protective plate No. n-1. A limit frame 18 is also provided at the bottom of the machine tool frame 1, with the side of the limit frame 18 contacting the outer side of the U-shaped groove 16 on protective plate No. n.

[0030] A nylon scraper strip 19 is provided on the inner side of the front end of the protective plate 6, and a first wedge block 20 is provided behind the nylon scraper strip 19. A second wedge block 21 is provided on the outer side of the rear end of the protective plate 6. The inclined surface on the second wedge block 21 matches the inclined surface on the first wedge block 20. A stop block 22 is provided on the inner side of the rear end of the protective plate 6. A protective plate housing 23 is also provided on the machine tool frame 1. The edge of the protective plate housing 23 is also provided with a nylon scraper strip 19 and a first wedge block 20 that match the outermost protective plate 6. At the same time, the innermost protective plate 6 is also connected to the cable chain bracket 26 in the machine tool frame 1. The cable chain bracket 26 is placed on both sides of the machine tool frame 1 through guide grooves 27 and guide rollers 28.

[0031] The slide support block 2 and the first guide bar 17 are both three segments of equal length, and the middle segment of the three slide support block 2 and the three first guide bars 17 is fixedly connected to the machine tool frame 1 by bolts.

[0032] The inner side of the front end of the protective plate 6 is also provided with a high-pressure nozzle 24, which is connected to the water pump in the flushing system through a hose.

[0033] Among the multiple protective plates 6, the outermost protective plate 6 is provided with a second guide bar, which is slidably connected in the guide groove 25 of the outer protective plate fixedly set on the machine tool frame 1.

[0034] The working process of the built-in flexible connection cable chain protection system of this invention is as follows: In the initial state, all the protective plates 6 are located inside the protective plate housing 23. When the cable chain moves, it will drive the innermost No. 1 protective plate 6 to move. When the second wedge block 21 on the outer side of the rear end of the No. 1 protective plate 6 moves to the first wedge block 20 set on the inner side of the No. 2 protective plate 6, the two collide. The No. 1 protective plate 6 will then drive the No. 2 protective plate 6 to move, until the No. 2 protective plate 6 drives the No. 3 protective plate 6 to move... and finally drives the nth protective plate 6 to move. When most of the nth protective plate 6 is also pulled out of the protective plate housing 23, the second wedge block 21 at the rear end of the nth protective plate 6 will be blocked by the first wedge block 20 set on the inner side of the protective plate housing 23. At this time, the protection system composed of multiple protective plates 6 is fully deployed, and the cable chain also moves to the extreme position in one direction.

[0035] When the cable chain moves in the reverse direction, it will first push the innermost protective plate 1 6, which is directly connected to it, to move in the reverse direction. The second wedge block 21 on the protective plate 1 6 will first separate from the first wedge block 20 on the protective plate 2 6. When the rear end of the protective plate 1 6 moves to the stop block 22 set at the inner rear end of the protective plate 2 6, it will push the stop block 22 and the protective plate 2 6 to move together... Finally, it will push the nth protective plate 6 to move. When the nth protective plate 6 returns to the initial position, its rear end will be blocked by the limit stop block set inside the protective plate housing 23. At this time, the protective system composed of multiple protective plates 6 will be completely retracted, and the cable chain will also move to the extreme position in another direction.

[0036] During the above-mentioned movement, the nylon scraper strip 19 provided at the front end of the protective plate 6 will scrape off the impurities and oil stains on the surface of the next level protective plate 6, preventing them from entering the gap between the two protective plates 6, thereby ensuring the normal operation of the protective plate 6.

[0037] When the protective plate 6 moves, the high-pressure nozzle 24 at its front end will spray high-pressure water under the action of the water pump. The high-pressure nozzle 24 can spray two streams of water at a 90° angle to wash away iron filings and dirt on the surface of the guide plate under the drag chain.

[0038] The protective plate 6 here is essentially slidably connected to the machine tool frame 1. The top of the protective plate 6 is slidably connected to the machine tool frame 1 via the protective plate slider 4, and its bottom is slidably connected to the machine tool frame 1 via the U-shaped groove 16.

[0039] The bottom edge of the protective plate slider 4 is slidably supported by the inclined slide groove 3, while its top edge is slidably connected to the upper slide rail composed of the inner upper slide rail and the outer upper slide rail. The outer upper slide rail is composed of the outer pressure block 7 directly connected to the machine tool frame 1 by fasteners such as bolts. Since this area is outside the processing area, it can be installed in this way. However, the inner upper slide rail is located inside the processing area, and the installation space is limited, so it cannot be installed in the above way. Therefore, the inner upper slide rail is formed by the inner pressure block 15 pressed by the top column 12. The inner pressure block 15 is pressed against the machine tool frame 1 by the spring 14 sleeved on the top column 12. The bottom edge of the inner upper slide rail is formed.

[0040] During the movement of the protective plate slider 5, the dustproof slider 10 set in the connecting block 5 will always be pressed against the gap between the protective plate slider 4 and the connecting block 5 under the action of the dustproof spring 9, preventing cutting chips and other impurities from entering between the protective plate slider 4 and the inclined slide groove, thereby ensuring the smooth and stable movement of the protective plate slider 4.

[0041] The U-shaped grooves 16 at the bottom of the protective plate 6 are nested and movably connected. The innermost U-shaped groove 16 is slidably connected to the first guide strip 17 fixedly connected to the machine tool frame 1, while the other U-shaped grooves 16 are slidably connected to the adjacent U-shaped grooves 16 in sequence. The limiting frame 18 fixed at the bottom of the machine tool frame 1 is pressed against the side wall of the outermost U-shaped groove 16 to prevent it from coming out of the previous U-shaped groove 16, thus playing the role of limiting and guiding.

[0042] If the cable chain has a problem and needs to be repaired or routinely maintained, the n protective plates 6 in this protection system need to be removed. When disassembling, first remove the limit frame 18, and then the outer U-shaped groove 16 can be pulled out from the previous inner U-shaped groove 16 in turn (the bottom of the protective plate 6 undergoes elastic deformation during the pulling process), thus realizing the disassembly of the lower structure of the protective plate 6.

[0043] Then, the middle section of the slide support block 2 is removed from the machine tool frame 1 (all the protective plates 6 have been moved in advance to a position where they will not interfere with the slide support block 2). At this time, a gap appears in the middle of the slide rail composed of the three slide support blocks 2, which can drive the protective plate 6 to move left and right, so that the protective plate slider 4 connected to it can move to the gap and be removed from the gap, thereby realizing the separation between the protective plate 6 and the machine tool frame 1.
