Description

Technical Field

[0001] This application relates to the field of CNC machine tool technology, specifically to a splash-proof device for CNC machine tools. Background Technology

[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, and input them into the CNC device via an information carrier. After processing, the CNC device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings.

[0003] Currently, CNC machine tools often produce flying debris when machining workpieces, which can easily lead to a dirty and messy machining environment and may also cause accidental injury to operators. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a CNC machine tool splash prevention device, which can block splashed debris during workpiece processing, thus preventing the debris generated during workpiece processing from causing environmental mess and accidental injury to operators. This solves the problem that current CNC machine tools often have debris flying out of the machine tool during workpiece processing, which easily leads to a messy processing environment and is prone to accidental injury to operators.

[0005] To achieve the aforementioned goal of blocking flying debris during workpiece processing and preventing the debris from causing environmental pollution and accidental injury to operators, this application provides the following technical solution: a CNC machine tool splash-proof device, including a machine tool base, a guide rail on the top of the machine tool base, a machining seat on the top of the guide rail via a support plate, a machining head connected to one side of the machining seat, and two ends of the machining seat fixed inside a support frame via fixing plates. Multiple splash-proof strips are connected around the support frame via multiple connecting components, and the multiple splash-proof strips surround the machining seat and machining head on the outside. A workpiece placement platform is provided on the top of the machine tool base, and a tool change box is provided at one end of the top of the machine tool base.

[0006] The above solution uses multiple splash guards surrounding the outside of the machining head to block the flying debris during workpiece processing. This effectively prevents the debris from causing environmental pollution and accidental injury to operators.

[0007] Furthermore, the connecting component includes a mounting frame, an mounting strip is inserted into the inner wall of the middle of the mounting frame, a connecting bracket is provided on the top of the mounting strip, and a splash guard is provided at the bottom of one end of the connecting bracket.

[0008] With the above solution, by pulling the installation strip out of the installation frame, the splash guard connected to the corresponding connecting bracket can be removed from the support frame, making it easy to replace the damaged splash guard. At the same time, when it is necessary to repair the internal structure of the support frame, the splash guard can be removed to facilitate the maintenance of the internal structure of the support frame by the staff.

[0009] Furthermore, the mounting frame includes multiple fixed mounting frames and one movable mounting frame. The multiple fixed mounting frames are fixedly disposed on the outer surface of the middle part of the support frame, and the movable mounting frame is slidably disposed on the side of the support frame near the cutter head replacement box. The position of the movable mounting frame corresponds to the position of the cutter head replacement box.

[0010] The above solution allows the height of the movable mounting frame to be adjusted as needed, thereby moving the corresponding splash guard.

[0011] Furthermore, two lifting frames are provided at both ends of the movable mounting frame. The bottom of the two lifting frames is connected to two rotating wheels through two rotating frames. The outer surface of the middle part of the two rotating wheels is slidably connected to the outer surface of the top of the two lifting platforms. The two lifting platforms are located on both sides of the tool head changing box. The lifting platforms are set on the top of the machine tool base, and the outer surface of one end of the top of the lifting platform is inclined.

[0012] With the above solution, when changing the cutting head requires moving the machining base and machining head above the cutting tool changing box, the outer surface of the middle of the rotating wheel slides on the inclined outer surface of one end of the top of the lifting platform. This causes the lifting frame, in conjunction with the rotating wheel and the lifting platform, to gradually move the movable mounting frame upwards. The movable mounting frame then moves the anti-splash strip upwards via the corresponding mounting strip and connecting frame. This prevents the anti-splash strip from being affected by the cutting tool changing box when the support frame moves it towards the cutting head changing box, thus preventing the anti-splash strip from being entangled and damaged due to the pushing action of the cutting head changing box.

[0013] Furthermore, the lifting frame is L-shaped, with the outer surface of the middle part of the long rod of the lifting frame slidably connected to the inner wall of the middle part of the limiting plate. The limiting plate is located on one side of the support frame, and the short rod of the lifting frame is located above the limiting plate.

[0014] The above solution uses the long rod of the lifting frame in conjunction with the limiting plate to fix the trajectory of the moving installation frame, thereby improving the stability of the moving installation frame during movement. The short rod of the lifting frame, restricted by the limiting plate, can limit the minimum height of the moving installation frame.

[0015] Furthermore, a telescopic rod is provided on the top of the movable mounting frame via a fixing frame. The top of the telescopic rod is fixed to one side of the support frame via a fixing plate. A spring is provided inside the telescopic rod, with one end of the spring located at one end of the telescopic inner rod and the other end of the spring located at one end of the inner wall of the telescopic outer tube.

[0016] With the above solution, the movable mounting frame can be pushed by the telescopic rod and spring through the fixed frame, and the spring force can quickly push the movable mounting frame downward to reset it.

[0017] Furthermore, the fixing frame is arranged in an inverted U-shape, the top of the fixing frame is fixedly connected to the bottom of the telescopic rod, the two ends of the bottom of the fixing frame are set at the two ends of the top of the movable mounting frame, and the length of the inner wall of the fixing frame is greater than the length of the corresponding mounting strip.

[0018] The above solution, by setting the shape of the fixing frame, can prevent the fixing frame from affecting the installation of the mounting strip inside the movable mounting frame.

[0019] Furthermore, the support frame is hinged to multiple observation windows at both ends and sides, and the observation windows are designed to flip up.

[0020] The above solution allows for convenient observation of the processing inside the support frame through the observation window. Furthermore, the upward-opening design of the observation window allows workers to easily clean the inside of the window when dirt or grime appears.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This CNC machine tool splash guard uses multiple splash guards surrounding the outside of the machining head to block the flying debris when the machining head is machining the workpiece. This effectively prevents the flying debris from causing a dirty and messy environment and from accidentally injuring the operator. Attached Figure Description

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 4 and Figure 5 This embodiment of a CNC machine tool splash-proof device includes a machine tool base 1, a guide rail 2 on the top of the machine tool base 1, a machining seat 4 on the top of the guide rail 2 via a support plate, a machining head 5 connected to one side of the machining seat 4, and the two ends of the machining seat 4 being fixed inside a support frame 3 via fixing plates. Multiple splash-proof strips 7 are connected around the support frame 3 via multiple connecting components 6, and the multiple splash-proof strips 7 surround the outside of the machining seat 4 and the machining head 5. A workpiece placement table 8 is provided on the top of the machine tool base 1, and a tool head replacement box 9 is provided at one end of the top of the machine tool base 1.

[0033] Please see Figure 4 , Figure 5 and Figure 6 The connecting component 6 includes a mounting frame 601, with a mounting strip 602 inserted into the inner wall of the middle part of the mounting frame 601. A connecting bracket 603 is provided on the top of the mounting strip 602, and a splash guard 7 is provided at the bottom of one end of the connecting bracket 603. By pulling the mounting strip 602 out of the mounting frame 601, the splash guard 7 connected to the corresponding connecting bracket 603 can be removed from the support frame 3, making it easy to replace the damaged splash guard 7. At the same time, when it is necessary to repair the internal structure of the support frame 3, the splash guard 7 can be removed to facilitate the maintenance of the internal structure of the support frame 3 by the staff.

[0034] Please see Figure 4 , Figure 5 and Figure 6The mounting frame 601 includes multiple fixed mounting frames 6011 and one movable mounting frame 6012. The multiple fixed mounting frames 6011 are fixedly set on the middle outer surface of the support frame 3, and the movable mounting frame 6012 is slidably set on the side of the support frame 3 near the cutter head replacement box 9. The position of the movable mounting frame 6012 corresponds to the position of the cutter head replacement box 9, so that the position and height of the movable mounting frame 6012 can be adjusted according to the situation, thereby driving the corresponding splash guard 7 to move.

[0035] Please see Figure 4 , Figure 5 and Figure 6 The movable mounting frame 6012 has two lifting frames 11 at both ends. The bottom of each lifting frame 11 is connected to two rotating wheels 12 via two rotating brackets. The outer surface of the middle part of each rotating wheel 12 is slidably connected to the outer surface of the top of each lifting platform 10. The two lifting platforms 10 are located on both sides of the tool head changing box 9. The lifting platforms 10 are positioned on top of the machine tool base 1, and one end of the top surface of each lifting platform 10 is inclined. When changing the tool head, it is necessary to move the machining seat 4 and machining head 5 above the tool head changing box 9, via the rotating wheels 11... 2. The middle outer surface slides on the inclined outer surface of the top end of the lifting platform 10, so that the lifting frame 11, together with the rotating wheel 12 and the lifting platform 10, gradually drives the movable mounting frame 6012 to move upward. The movable mounting frame 6012 drives the anti-splash strip 7 to move upward through the corresponding mounting strip 602 and connecting frame 603. This prevents the anti-splash strip 7 from being affected by the cutter head replacement box 9 when the support frame 3 drives the anti-splash strip 7 to move towards the cutter head replacement box 9, and prevents the anti-splash strip 7 from being entangled and damaged by the push of the cutter head replacement box 9.

[0036] Please see Figure 6 The lifting frame 11 is L-shaped. The outer surface of the middle part of the long rod of the lifting frame 11 is slidably connected to the inner wall of the middle part of the limiting plate 13. The limiting plate 13 is set on one side of the support frame 3. The short rod of the lifting frame 11 is located above the limiting plate 13. The long rod of the lifting frame 11, in conjunction with the limiting plate 13, can fix the trajectory of the moving installation frame 6012, thereby improving the stability of the moving installation frame 6012 when it moves. The short rod of the lifting frame 11, restricted by the limiting plate 13, can limit the minimum height of the moving installation frame 6012.

[0037] Please see Figure 1 , Figure 4 and Figure 6The top of the movable mounting frame 6012 is provided with a telescopic rod 15 via a fixing frame 14. The top of the telescopic rod 15 is fixed to one side of the support frame 3 via a fixing plate. A spring 16 is provided inside the telescopic rod 15. One end of the spring 16 is provided at one end of the telescopic inner rod of the telescopic rod 15, and the other end of the spring 16 is provided at one end of the inner wall of the telescopic outer tube of the telescopic rod 15. The movable mounting frame 6012 can be pushed by the fixing frame 14 through the telescopic rod 15 and the pushing force of the spring 16 can quickly push the movable mounting frame 6012 downward to reset.

[0038] Please see Figure 1 , Figure 2 and Figure 6 The fixing frame 14 is inverted U-shaped. The top of the fixing frame 14 is fixedly connected to the bottom of the telescopic rod 15. The two ends of the bottom of the fixing frame 14 are set at the two ends of the top of the movable mounting frame 6012. The length of the inner wall of the fixing frame 14 is greater than the length of the corresponding mounting strip 602. The shape of the fixing frame 14 can prevent the fixing frame 14 from affecting the installation of the mounting strip 602 in the movable mounting frame 6012.

[0039] Please see Figure 1 , Figure 3 and Figure 4 The support frame 3 has multiple observation windows 17 hinged to its two ends and sides. The observation windows 17 are designed to flip up, allowing easy observation of the internal processing of the support frame 3. The flip-up design of the observation windows 17 also allows workers to easily open and clean the inside of the observation windows 17 when dirt appears on the inside.

[0040] In this embodiment, a CNC machine tool splash prevention device is provided. Multiple splash prevention strips 7 surround the outside of the machining head 5, so that the debris splashed by the machining head 5 when machining the workpiece is blocked by the multiple splash prevention strips 7. This achieves the effect of blocking the splashed debris when machining the workpiece, avoiding the debris generated during the machining process from causing environmental mess and accidental injury to the operator.

[0041] The working principle of the above embodiment is as follows: The workpiece to be processed is placed on the top of the workpiece placement table 8 and fixed. The processing seat 4 moves on the top of the machine tool base 1 via the guide rail 2, driving the processing head 5 to move above the workpiece. The processing position of the processing head 5 on the workpiece is adjusted. When the processing head 5 processes the workpiece below, the flying debris is blocked by the anti-splash strip 7 to prevent the debris from flying to the outside. When it is necessary to change the cutting head of the processing head 5, the processing seat 4 moves on the top of the machine tool base 1 via the guide rail 2 towards the cutting head replacement box 9. When the processing seat 4 drives the support frame 3 to move, it will drive the rotating wheel 12 to roll on the outer surface of the top of the lifting table 10. The rotating wheel 12 will push the lifting frame 11 upward through the inclined outer surface of one end of the top of the lifting table 10, so that the lifting frame 11 drives the movable mounting frame 6012 upward. At the same time, the movable mounting frame 6012 will be fixed. The frame 14 pushes the telescopic rod 15 to retract, compressing the spring 16. The movable mounting frame 6012, through the corresponding mounting strip 602 and the connecting frame 603, moves the corresponding splash guard 7 upward, raising its height and preventing it from contacting the tool change box 9 via the movement of the support frame 3. This continues until the machining head 5 moves above the tool change box 9, allowing it to be replaced with a tool. When the machining seat 4 is reset after replacement, the spring 16 releases its thrust, causing the telescopic rod 15 to extend and push the movable mounting frame 6012 downward via the fixed frame 14, resetting the movable mounting frame 6012 and the corresponding splash guard 7. When the splash guard 7 needs to be removed, the connecting frame 603 is pulled upward, causing the mounting strip 602 to be pulled out of the mounting frame 601, thus removing the splash guard 7 from the support frame 3.
