Detailed Implementation

[0018] 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.

[0019] Please see Figures 1-4 A CNC vertical milling machine with a lifting table includes a machining table 1, a lifting mechanism 2, and a milling cutter mechanism 3. The lifting mechanism 2 is installed at the rear of the machining table 1, and the milling cutter mechanism 3 is installed at the front of the lifting mechanism 2. A slide rail 4 is fixed to the front of the machining table 1. A T-shaped slide block 5 is slidably connected to the front of the slide rail 4. A protective plate 6 is fixed to the upper end of the slide block 5. An upper rack 8 is fixed to the upper end inside the slide rail 4. A vertical channel 10 is opened at the front of the slide block 5. A slider 14 is slidably connected inside the vertical channel 10. A spring 13 is connected between the lower end of the slider 14 and the bottom end inside the vertical channel 10. The front end of the slider 14 extends out of the vertical channel 10 and is fixed with a pressure plate 11. A storage groove 16 is provided at the upper rear of the slide block 5. A limit component is slidably connected inside the storage groove 16. The limit component is engaged with the upper rack 8. The limit component includes a sliding plate 18 and a lower rack 20. The sliding plate 18 is slidably connected to the storage groove 16. Inside the 6, the lower rack 20 is fixed to the upper end of the slide plate 18, the limiting component is fixed to the slider 14, and a connecting channel 17 is provided between the vertical channel 10 and the storage groove 16. A connecting block 19 is slidably connected inside the connecting channel 17. The front end of the connecting block 19 is fixed to the rear end of the slider 14, and the rear end of the connecting block 19 is fixed to the front end of the slide plate 18. When the milling cutter mechanism 3 processes the workpiece, the pressure plate 11 is pressed down, and the pressure plate 11 drives the slider 14 to move down and compress the spring 13. The slider 14 then drives the connecting block 19 to move down inside the connecting channel 17. The connecting block 19 will drive the slide plate 18 to move down inside the storage groove 16. At this time, the lower rack 20 moves into the storage groove 16 and separates from the upper rack 8, so that the slide block 5 and the slide rail 4 are no longer jammed. Then the pressure plate 11 can be pushed. The pressure plate 11 drives the slide block 5 to move horizontally along the slide rail 4. The slide block 5 drives the protective plate 6 to move, moving the protective plate 6 to the front of the milling cutter mechanism 3.

[0020] The slide rail 4 has guide grooves 7 at both the upper and lower ends. The upper rack 8 is fixed to the bottom of the upper guide groove 7. The lower rear end of the slide block 5 is fixed with a guide block 9. The guide block 9 is slidably connected to the lower guide groove 7. When the slide block 5 slides, it can drive the guide block 9 to slide inside the lower guide groove 7. Through the cooperation between the guide block 9 and the guide groove 7, the slide block 5 can be prevented from moving forward and separating from the slide rail 4.

[0021] After the pressure plate 11 is released, the spring 13 drives the slider 14 to reset. The slider 14 drives the pressure plate 11 and the connecting block 19 to move upward and reset. The connecting block 19 then drives the slide plate 18 to move upward and reset, so that the slide plate 18 drives the lower rack 20 to insert into the upper guide groove 7 and mesh with the upper rack 8. In this way, the slide rail 4 and the slide block 5 are engaged, so that even if the milling cutter in the milling cutter mechanism 3 breaks, it will not injure the user. It can be blocked by the protective plate 6, which can improve the safety of the user standing in front of the CNC vertical lifting milling machine.

[0022] A guide rod 12 is fixed inside the vertical channel 10. The guide rod 12 passes through the slider 14. The guide rod 12 is located inside the spring 13. When the slider 14 moves up and down inside the vertical channel 10, it will move along the guide rod 12. The guide rod 12 plays a guiding and limiting role for the slider 14.

[0023] The upper end of the pressure plate 11 is provided with a plurality of anti-slip protrusions 15. The anti-slip protrusions 15 are made of rubber. By providing anti-slip protrusions 15 on the upper end of the pressure plate 11, the pressure plate 11 can be pressed and pushed to prevent slipping.

[0024] Working principle: When the milling cutter mechanism 3 processes the workpiece, pressing down the pressure plate 11 causes the slider 14 to move downwards, compressing the spring 13. The slider 14 then causes the connecting block 19 to move downwards within the connecting channel 17. The connecting block 19 then causes the sliding plate 18 to move downwards within the receiving groove 16. At this time, the lower rack 20 moves into the receiving groove 16 and separates from the upper rack 8, so that the slide 5 and the slide rail 4 are no longer jammed. Then, the pressure plate 11 can be pushed, causing the slide 5 to move horizontally along the slide rail 4. The slide 5 then moves the protective plate 6, thus protecting the workpiece. When plate 6 moves to the front of milling cutter mechanism 3 and pressure plate 11 is released, spring 13 drives slider 14 to reset. Slider 14 drives pressure plate 11 and connecting block 19 to move up and reset. Connecting block 19 then drives slide plate 18 to move up and reset, so that slide plate 18 drives lower rack 20 to insert into upper guide groove 7 and mesh with upper rack 8. In this way, slide rail 4 and slide block 5 are engaged, so that even if the milling cutter in milling cutter mechanism 3 breaks, it will not injure the user. It can be blocked by protective plate 6, which can improve the safety of the user standing in front of CNC vertical lifting milling machine.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
