Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As shown in the attached Figure 1-6 A cutting machine with a protection mechanism shown in the figure includes a support base 1. A column 2 is provided on the rear side of the surface of the support base 1. A first protective cover 3 is provided on the surface of the support base 1. An eye protection piece 4 is embedded and installed on the surface of the first protective cover 3. A second protective cover 5 is provided on the surface of the column 2. The cross-section of the second protective cover 5 is larger than that of the first protective cover 3. An installation groove is provided on the surface of the column 2. A lead screw 19 is provided inside the installation groove. A moving rod 20 is provided outside the lead screw 19. The top of the lead screw 19 is provided with a second motor 21. The output end of the second motor 21 is coaxially and drivably connected to the lead screw 19 inside the installation groove. The moving rod 20 is threadedly connected to the outside of the lead screw 19, and one end of the moving rod 20 is fixedly connected to the second protective cover 5. An electric push rod 6 is provided on the top of the second protective cover 5. A support frame 7 is provided inside the second protective cover 5. A cutting knife 8 is provided inside the support frame 7. A first motor 9 is provided on the outer wall of the support frame 7. The output end of the electric push rod 6 extends into the second protective cover 5 and is connected to the surface of the support frame 7. The output end of the first motor 9 is coaxially and drivably connected to the cutting knife 8 inside the support frame 7.

[0024] Specifically, in this structure, in order to protect the workpiece during cutting and prevent the chips generated during cutting from splashing, specifically, the workpiece to be cut is fixed at the first protective cover 3. At this time, the second motor 21 is started to drive the screw rod 19 inside the installation groove to rotate, so that the moving rod 20 drives the second protective cover 5 to move towards the surface of the first protective cover 3, and the second protective cover 5 is covered on the top of the first protective cover 3 for protection. At the same time, the electric push rod 6 drives the support frame 7 to move towards the surface of the workpiece, and the first motor 9 drives the cutting tool 8 inside the support frame 7 to rotate, so as to cut the workpiece. During the cutting process, the generated chips are blocked by the first protective cover 3 and the second protective cover 5, thus avoiding affecting the cutting personnel and achieving a good protective effect. Moreover, during the cutting process, the cutting personnel can observe the cutting situation of the workpiece inside the first protective cover 3 through the protective lens 4 on the surface of the first protective cover 3. At the same time, the goggles can prevent the eyes of the cutting personnel from being affected by strong light.

[0025] In a specific embodiment, as shown in the attached Figure 1 , 4 figures, an absorption and purification structure is jointly installed on the outer walls of the first protective cover 3 and the second protective cover 5. The absorption and purification structure includes two dust suction hoods 10, which are respectively installed on the outer walls of the first protective cover 3 and the second protective cover 5. One ends of the two dust suction hoods 10 are jointly installed with a conveying hose 11. A purification box 12 is arranged on the surface of the support seat 1 on one side of the first protective cover 3. A dust suction pump 13 is arranged on one side of the purification box 12. The input end and the output end of the dust suction pump 13 are respectively provided with a connecting pipe 14 and a communicating pipe 15. The two dust suction hoods 10 are respectively communicated with the first protective cover 3 and the second protective cover 5, and a filter screen is installed inside the dust suction hood 10. The input end and the output end of the dust suction pump 13 are respectively connected with the connecting pipe 14 and the communicating pipe 15. One end of the communicating pipe 15 extends into the interior of the purification box 12, and one end of the connecting pipe 14 is communicated with the conveying hose 11. A discharge pipe 16 is communicated with the outer wall of the purification box 12. A filter screen 17 is arranged inside the purification box 12, and an activated carbon adsorption net 18 is arranged on one side of the filter screen 17. Two installation grooves are formed on the surface of the purification box 12, and sealing plates 30 are installed inside the two installation grooves through screws. One ends of the filter screen 17 and the activated carbon adsorption net 18 are respectively connected with the corresponding sealing plates 30, and pull grooves are formed on the surfaces of the sealing plates 30.

[0026] Specifically, in this structure, during the cutting process of the workpiece, the generated dust and irritating fumes will fill the interiors of the first protective cover 3 and the second protective cover 5, which not only affects the cutting personnel's observation of the cutting situation of the workpiece inside the first protective cover 3 through the protective lens 4, but also easily affects the health of the cutting personnel.

[0027] Furthermore, during the cutting process, through the dust suction pump 13, the smoke and dust diffused inside the first protective cover 3 and the second protective cover 5 are sucked into the interior of the conveying hose 11 through the dust suction hood 10, and enter the interior of the purification box 12 through the connecting pipe 14 and the communicating pipe 15. The smoke and dust entering the interior of the purification box 12 are filtered and adsorbed through the filter screen 17 and the activated carbon adsorption screen 18, and finally discharged.

[0028] The operator can remove the screws at the sealing plate 30 and pull the sealing plate 30 through the slot, so as to draw out the activated carbon adsorption screen 18 and the filter screen 17 from the interior of the purification box 12, which is convenient for disassembling and cleaning the filter screen 17 and the activated carbon adsorption screen 18.

[0029] It should be noted that in this structure, one end of the two dust suction hoods 10 is jointly installed with a conveying hose 11. The conveying hose 11 has a certain length and will not affect the movement of the first protective cover 3 and the second protective cover 5. Secondly, filter screens are installed at both dust suction hoods 10, and the dust suction pump 13 will not be damaged due to dust.

[0030] In a specific embodiment, as shown in Figure 1 、 5 、6, through holes 22 are respectively formed through the two outer walls of the first protective cover 3. A locking plate 23 is installed inside the through holes 22. An arc-shaped groove is formed at the bottom of the locking plate 23. An arc-shaped clamping block 24 is arranged inside the arc-shaped groove. A number of compression springs 25 are arranged between the arc-shaped groove and the arc-shaped clamping block 24. Rectangular grooves are respectively formed on the two inner walls of the through holes 22. A threaded rod 26 is arranged inside one of the rectangular grooves, and a guide rod 27 is arranged inside the other rectangular groove. Threaded blocks 28 and guide blocks 29 are respectively arranged on the outer parts of the threaded rod 26 and the guide rod 27. An adjusting block is arranged at the top of the threaded rod 26. The threaded block 28 and the guide block 29 are respectively in threaded connection and sliding connection with the threaded rod 26 and the guide rod 27, and the threaded block 28 and the guide block 29 are respectively fixedly installed on the two outer walls of the locking plate 23.

[0031] Specifically, in this structure, when placing the workpiece to be cut on the first protective cover 3 for fixation, first place the workpiece inside the first protective cover 3 through the two through holes 22, and rotate the adjusting block, so that the adjusting block drives the threaded rod 26 inside one of the rectangular grooves to rotate. The rotation of the threaded rod 26 drives the threaded block 28 to move. Under the sliding guidance of the guide block 29 on the outer part of the guide rod 27, the locking plate 23 moves up and down inside the through holes 22. When the locking plate 23 moves downward, the workpiece will be clamped and fixed between the arc-shaped clamping block 24 and the through holes 22, avoiding the offset of the workpiece during cutting. At the same time, a number of compression springs 25 between the arc-shaped clamping block 24 and the arc-shaped groove can facilitate the clamping and fixing operation of workpieces with different outer diameters.

[0032] Working principle of the utility model:

[0033] When the above structure is in specific use, first, the operator places the workpiece to be cut inside the placement through groove 22 opened in the first protective cover 3. Through the movement of the threaded block 28 and the guide block 29, the locking plate 23 extends downward, clamping the workpiece between the placement through groove 22 and the arc-shaped clamping block 24 for clamping and fixing, so as to prevent the workpiece from shifting during subsequent cutting;

[0034] Then, the second motor 21 drives the lead screw 19 inside the installation groove to rotate, so that the moving rod 20 drives the second protective cover 5 to cover the top of the first protective cover 3 for protection. At the same time, the first motor 9 drives the cutting tool 8 inside the support frame 7 to rotate, and the electric push rod 6 drives the support frame 7 to move towards the surface of the workpiece, so that the rotating cutting tool 8 cuts the workpiece. During the cutting process, the cutting personnel can observe the cutting situation of the workpiece inside the first protective cover 3 through the protective lens 4 on the surface of the first protective cover 3. The debris generated during cutting is blocked by the first protective cover 3 and the second protective cover 5, so as to achieve the protective effect;

[0035] Finally, during the cutting process, the dust suction pump 13 sucks the smoke and dust diffused inside the first protective cover 3 and the second protective cover 5 into the inside of the suction hose 11 through the suction hood 10, and enters the inside of the purification box 12 through the connecting pipe 14 and the communicating pipe 15. The smoke and dust entering the inside of the purification box 12 are filtered and adsorbed by the filter screen 17 and the activated carbon adsorption net 18, and finally discharged, so as to prevent the dust and smoke from diffusing inside the first protective cover 3 and the second protective cover 5 and affecting the operation and health of the cutting personnel.

[0036] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
