[0018] (III) Beneficial Effects

[0019] This utility model provides a highly wear-resistant protective cover for CNC machine tool guideways. It has the following beneficial effects:

[0020] (I) This high wear-resistant CNC machine tool guide rail protective cover has a protective mechanism that forms a protective space through a protective frame and a protective pad made of iron sheet. The magnetic adsorption of the magnet on the top surface of the protective frame ensures the stable fixation of the protective pad, and the sliding sleeve drives the mounting bracket to move so that the protective pad wrapped on the rotating shaft can be unfolded or retracted with it.

With the help of the spring in the initial compressed state on the buffer plate connecting frame and the fixed frame connecting plate, the impact force is converted into elastic potential energy. The damper consumes energy, effectively reducing the vibration amplitude of the buffer plate and reducing the impact of vibration on the guide rail and protective cover. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 The present invention provides a technical solution: including a base 1, and a protective mechanism 2 and a buffer mechanism 3 are provided on the top of the base 1;

[0030] The protective mechanism 2 is located inside the buffer mechanism 3;

[0031] Protection mechanism 2 includes a protection section and a movement section;

[0032] The protective part includes a protective frame 21 and a toothed plate 26, and the moving part includes a guide rail 29 and a sliding sleeve 24;

[0033] The guide rail 29 is located inside the protective frame 21. The bottom surface of the guide rail 29 is fixedly connected to the top surface of the base 1, and the bottom surface of the protective frame 21 is fixedly connected to the top surface of the base 1. The outer wall of the guide rail 29 is slidably connected to the inner side of the sliding sleeve 24, and the outer wall of the sliding sleeve 24 is slidably connected to the outer wall of the protective frame 21. Two mounting brackets 23 are fixedly installed on the outer wall of the sliding sleeve 24. Two rotating shafts 210 are rotatably installed on the inner side of the two mounting brackets 23 through two bearing seats. Two protective pads 22 are wound around the outer wall of the two rotating shafts 210. The far end face of the two protective pads 22 is fixedly connected to the outer wall of the protective frame 21. A control frame 25 is fixedly installed on the top surface of the sliding sleeve 24. The two mounting brackets 25 are slidably connected to the outer wall of the protective frame 21. Two rotating rods 27 are respectively provided through the outer wall of the 3rd and extend to the inner side of the two mounting brackets 23. The side of the two rotating rods 27 near the two rotating shafts 210 is fixedly connected to the outer wall of the two rotating shafts 210. The outer wall of the protective frame 21 is fixedly connected to the outer wall of the toothed plate 26. Two gears 28 are fixedly sleeved on the outer wall of the two rotating rods 27 respectively. The tooth surfaces of the two gears 28 mesh with the tooth surfaces of the toothed plate 26. Two mounting slots are opened on the top surface of the protective frame 21. Two magnets 211 are fixedly installed on the inner wall of the two mounting slots respectively. The two protective pads 22 are made of iron sheets. The two magnets 211 are magnetically attracted to the two protective pads 22 respectively. The protection mechanism 2 is provided with two sets.

[0034] The buffer mechanism 3 includes a fixed frame 31, the bottom surface of which is fixedly connected to the top surface of the base 1. A through groove is opened through the top surface of the fixed frame 31, and the inner wall of the through groove is slidably connected to the outer wall of the control frame 25. Two buffer grooves are opened through the top surface of the fixed frame 31, and two buffer plates 32 are slidably arranged on the inner walls of the two buffer grooves respectively. Two sets of connecting frames 33 are fixedly arranged on the top surface of the two buffer plates 32 respectively. Two sets of connecting plates 36 are fixedly arranged on the outer wall of the fixed frame 31. Two sets of springs 34 and two sets of dampers 35 are fixedly arranged on the top surface of the two sets of connecting plates 36 respectively. The top surfaces of the two sets of springs 34 and two sets of dampers 35 are fixedly connected to the inner side of the two sets of connecting frames 33 respectively. The initial state of the two sets of springs 34 is compressed. The buffer mechanism 3 is provided with two sets.

[0035] When the CNC machine tool guide rail needs protection, since the bottom surface of the guide rail 29 is fixed to the top surface of the base 1, the sliding sleeve 24 is fitted on the outer wall of the guide rail 29 and can slide along it. The outer wall of the sliding sleeve 24 is also slidably connected to the outer wall of the protective frame 21. When the sliding sleeve 24 slides on the guide rail 29, it drives the mounting bracket 23 installed on its outer wall to move. The protective pad 22 is wound on the rotating shaft 210, which is rotatably set through the bearing seat inside the mounting bracket 23. One end of the protective pad 22 is fixed to the outer wall of the protective frame 21. The movement of the sliding sleeve 24 causes the mounting bracket 23 to move, which in turn causes the rotating shaft 210 to rotate, so that the protective pad 22 can be unfolded or retracted as the sliding sleeve 24 moves.

[0036] During the unfolding of the protective pad 22, the protective frame 21 and the protective pad 22 together form a protective space for the guide rail 29, preventing foreign objects such as chips and coolant from entering the guide rail 29. The toothed plate 26 on the outer wall of the protective frame 21 meshes with the gear 28 fixedly sleeved on the rotating rod 27. When the sliding sleeve 24 moves and drives the rotating rod 27 to rotate, the gear 28 rolls on the toothed plate 26, ensuring that the unfolding and retraction of the protective pad 22 is stable and smooth. The magnet 211 in the mounting groove on the top surface of the protective frame 21 magnetically attracts the iron sheet material protective pad 22, and stably fixes it on the protective frame 21 when the protective pad 22 is unfolded.

[0037] The bottom surface of the fixed frame 31 of the buffer mechanism 3 is fixed to the top surface of the base 1. The control frame 25 passes through the through groove on the top surface of the fixed frame 31 and is slidably connected to the inner wall of the through groove. When the CNC machine tool vibrates or is impacted by external force, the sliding sleeve 24 drives the control frame 25 to move up and down in the through groove. The buffer plate 32 in the buffer groove on the top surface of the fixed frame 31 also slides up and down accordingly. The connecting frame 33 on the top surface of the buffer plate 32 is connected to the spring 34 and damper 35 on the connecting plate 36 on the outer wall of the fixed frame 31. The spring 34 is initially in a compressed state. When the buffer plate 32 is subjected to external force and moves downward, the spring 34 is further compressed, converting the impact force into elastic potential energy. The damper 35 consumes energy, reduces the vibration amplitude of the buffer plate 32, reduces the impact of vibration on the guide rail 29 and the entire protective cover, and improves the protective performance of the protective cover and the stability of the CNC machine tool.
