Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool tool protection technology, specifically a CNC machine tool with retractable tool. Background Technology

[0002] Numerical control machine tools are a type of automated machine tool equipped with a program control system. They can be instructed to move and process parts according to a pre-programmed program.

[0003] Currently, in common CNC machine tools with retractable tool functions, the fixed position of the tool is affected during actual use, and the cutting debris after cleaning the tool surface requires secondary cleaning. For example, CN220838914U discloses a CNC machine tool with retractable tool, including a CNC machine tool body, a machine tool guide rail inside the CNC machine tool body, a mounting base slidably connected to the outer side of the machine tool guide rail, a protective chamber fixed on the upper surface of the mounting base, a cleaning mechanism on the upper surface of the protective chamber, and a telescopic mechanism inside the mounting base.

[0004] As can be seen from the above-disclosed solution, the cutting tool's movement and extension are controlled by a telescopic mechanism installed within the mounting base. However, the vibration generated by the cutting tool during long-term machining can damage the threads of the screw and barrel of the telescopic mechanism, causing the cutting tool to move horizontally and thus affecting the accuracy of its movement position. Simultaneously, the cleaning nozzle, located inside the protective chamber, cleans the cutting debris adhering to the tool's surface after it retracts. This results in a large accumulation of debris within the protective chamber, requiring the user to clean the debris inside again. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a CNC machine tool with retractable cutting tools, which solves the problems of cutting tool extension and retraction affecting feed accuracy and requiring secondary cleaning of cutting chips.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a CNC machine tool with retractable cutting tools, comprising a CNC machine tool body, a machine tool guide rail fixedly connected to the surface of the CNC machine tool body, a mounting base slidably connected to the surface of the machine tool guide rail, a tool holder fixedly connected to the top of the mounting base, a pressure plate tightly fastened to the surface of the tool holder by threads, a cutting tool clamped between the pressure plate and the tool holder, a protective mechanism provided on the surface of the mounting base, a cleaning component fixedly connected to one end of the protective mechanism, the protective shell can move horizontally under the drive of an electric telescopic rod, thereby allowing the cutting tool to retract into the protective groove when not in use, which not only facilitates the addition of the tool to existing machine tools, but also does not affect the fixed position of the cutting tool, and the first, second and third brush bristles can clean the cutting debris adhering to the surface of the cutting tool when the cutting tool is retracted into the protective groove, which can prevent the debris from remaining in the protective groove and requiring secondary cleaning.

[0007] Preferably, the protective mechanism includes a protective shell, the bottom of which is slidably connected to the surface of the mounting base. The protective shell has a protective groove inside, one end of which is fixedly connected to an opening. The inner wall of the protective groove is slidably connected to the surface of the tool holder. When the protective shell moves to the left, the tool can be retracted to the right into the protective groove for protection, preventing workers from accidentally touching the tool and getting injured.

[0008] Preferably, the cleaning component includes a first bristle, a second bristle, and a third bristle. One end of the first bristle, the second bristle, and the third bristle is fixedly connected to the inner wall of the opening, and one end of the first bristle, the second bristle, and the third bristle contacts the surface of the tool. During the process of the tool retracting into the protective groove, the debris adhering to the surface of the tool can be cleaned.

[0009] Preferably, symmetrical push plates are fixedly connected to the outer side of the protective shell, and an electric telescopic rod is fixedly connected to the surface of the push plate. The bottom of the electric telescopic rod is fixedly connected to the surface of the mounting base.

[0010] Preferably, the top of the protective shell is snapped with a cover plate, the top of the cover plate is fixedly connected with a handle, and the bottom of the cover plate is fixedly connected with a fixing frame. The cover plate is easy to open and close manually and facilitates the replacement of the tool later.

[0011] Preferably, the inner wall of the protective groove is fixedly embedded with a first adsorption block and a second adsorption block. Both the first adsorption block and the second adsorption block are made of strong magnets.

[0012] Preferably, the outer side of the fixing frame is movably connected to the inner wall of the protective groove. The fixing frame is made of elastic anti-slip rubber. When the fixing frame is sleeved with the inner wall of the protective groove, it is squeezed to generate compressive elastic force, and the closed position of the cover plate is fixed by elastic tension.

[0013] Compared with the prior art, this utility model provides a CNC machine tool with retractable cutting tools, which has the following beneficial effects:

[0014] The protective shell can move horizontally under the drive of the electric telescopic rod, so that the tool can be retracted into the protective groove when not in use.

[0021] 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.

[0022] This utility model provides a technical solution: a CNC machine tool with retractable cutting tools, comprising a CNC machine tool body 1. The CNC machine tool body 1 integrates the latest technologies in mechanics, automation, computers, measurement, and microelectronics. Its basic components include a machining program carrier, a CNC device, a servo drive device, the machine tool body, and other auxiliary devices. It can operate and process parts according to a pre-programmed program. A machine tool guide rail 11 is fixedly connected to the surface of the CNC machine tool body 1. The machine tool guide rail 11 facilitates the movement of the mounting base 12, thereby driving the cutting tool 14 to move and feed. The mounting base 12 is slidably connected to the surface of the machine tool guide rail 11, and a tool holder 13 is fixedly connected to the top of the mounting base 12. The tool holder 13 and the pressure plate 15 are used to fix the tool 14. The tool 14 can be replaced. The surface of the tool holder 13 is fastened to the pressure plate 15 by threads. The tool 14 is clamped between the pressure plate 15 and the tool holder 13. The surface of the mounting base 12 is provided with a protective mechanism 2. The protective mechanism 2 can store the unused tool 14, thereby preventing personnel from accidentally touching the tool 14 and getting injured. Moreover, the protective mechanism 2 is easy to install on existing CNC machine tools and is easy to promote. One end of the protective mechanism 2 is fixedly connected to a cleaning component 4. The cleaning component 4 can sweep off the cutting chips adhering to the surface of the tool 14 when the protective mechanism 2 moves, so that the chips will not accumulate on the top of the mounting base 12.

[0023] The protective mechanism 2 includes a protective shell 21. The bottom of the protective shell 21 is slidably connected to the surface of the mounting base 12. The protective shell 21 has a protective groove 22 inside. One end of the protective groove 22 is fixedly connected to an opening 25. The inner wall of the protective groove 22 is slidably connected to the surface of the tool holder 13. When the protective shell 21 moves to the left, it can retract the tool 14 to the right into the protective groove 22 for protection, preventing the staff from accidentally touching the tool 14 and getting injured. Symmetrical push plates 26 are fixedly connected to the outside of the protective shell 21. An electric telescopic rod 27 is fixedly connected to the surface of the push plate 26. The bottom of the electric telescopic rod 27 is fixedly connected to the surface of the mounting base 12. The electric telescopic rod 27 can drive the protective shell 21 to move horizontally, so that the tool 14 can enter and exit the protective groove 22.

[0024] The cleaning component 4 includes a first bristle 41, a second bristle 42, and a third bristle 43. One end of the first bristle 41, the second bristle 42, and the third bristle 43 is fixedly connected to the inner wall of the opening 25. One end of the first bristle 41, the second bristle 42, and the third bristle 43 contacts the surface of the blade 14. During the process of the blade 14 retracting into the protective groove 22, the debris adhering to the surface of the blade 14 can be cleaned. The top of the protective shell 21 is snapped with a cover plate 3. The top of the cover plate 3 is fixedly connected with a handle 32, and the bottom of the cover plate 3 is fixedly connected with a fixing frame 31. The cover plate 3 is easy to open and close manually, and it is convenient to replace the blade 14 later.

[0025] The inner wall of the protective groove 22 is fixedly inlaid with a first adsorption block 23 and a second adsorption block 24. Both the first adsorption block 23 and the second adsorption block 24 are made of strong magnets. Iron plates are provided at both ends of the knife holder 13. When the iron plates are magnetically adsorbed with the second adsorption block 24, the rightward movement position of the protective shell 21 is positioned. The first adsorption block 23 and the second adsorption block 24 can fix the movement position of the protective shell 21 by magnetic adsorption force. The outer side of the fixing frame 31 is movably connected to the inner wall of the protective groove 22. The fixing frame 31 is made of elastic non-slip rubber. When the fixing frame 31 is sleeved with the inner wall of the protective groove 22, it is squeezed to generate compressive elastic force, and the closed position of the cover plate 3 is fixed by elastic tension.

[0026] The working principle of this device is as follows: After the CNC machine tool body 1 stops, the electric telescopic rod 27 is opened, causing the electric telescopic rod 27 to extend to the left. The extension of the electric telescopic rod 27 to the left drives the push plate 26 to move to the left. The movement of the push plate 26 to the left drives the protective shell 21 to move to the left. The movement of the protective shell 21 to the left causes the first brush bristles 41, the second brush bristles 42, and the third brush bristles 43 to move to the left along the surface of the tool 14, sweeping off the machining debris on the surface of the tool 14. The movement of the protective shell 21 to the left causes the tool 14 to retract to the right into the protective groove 22. When the protective shell 21 moves to the left and is in place, the electric telescopic rod 27 stops working. At this time, the surface of the first adsorption block 23 contacts the surface of the tool holder 13, and the protective position of the protective shell 21 is fixed by magnetic adsorption force.
