Abstract
Description
Technical Field
[0001] This utility model relates to the field of CNC lathe machining technology, specifically to a CNC lathe cutting device. Background Technology
[0002] CNC lathes are among the most widely used CNC machine tools. They are mainly used for cutting and machining the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. They can also perform grooving, drilling, reaming, boring, and reaming.
[0003] When machining the outer curved surface of shaft parts on a CNC lathe, in order to prevent the cutting head from overheating and causing damage, it is necessary to cool the cutting head synchronously during the operation. The existing cooling method uses a cooling head to spray cooling water onto the cutting tool to cool it down. When the sprayed water hits the cutting tool, it splashes, leaving water stains on the cutting tool and the outer curved surface of the shaft part. It also causes the cutting debris to stick to the cutting tool and the outer curved surface of the shaft part, requiring subsequent cleaning of the cutting tool and the outer curved surface of the shaft part, which consumes production time.
[0004] To address the aforementioned technical problems, this application proposes a CNC lathe cutting device. Utility Model Content
[0005] I. Technical problems to be solved
[0006] The technical problem this invention aims to solve is that when a cooling head sprays cooling water onto a cutting blade to cool it down, the water splashes when it hits the blade, leaving water stains on the outer curved surfaces of the cutting blade and shaft parts. This also causes the cutting debris to stick to the outer curved surfaces of the cutting blade and shaft parts, requiring subsequent cleaning of these surfaces.

[0024] 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 in 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.
[0025] Embodiment 1
[0026] As shown in the attached Figure 3 figure, a cutting device of a numerical control lathe includes a mounting plate 1 and a cutting tool head 8. A propulsion component is installed on the upper side of the mounting plate 1. The propulsion component includes a hydraulic telescopic rod 3 fixedly installed on the upper side of the mounting plate 1. An installation kit 5 is installed at the extending end of the hydraulic telescopic rod 3. An installation convex block 6 is integrally cast on the upper side of the cutting tool head 8. The installation convex block 6 is inserted into the interior of the installation kit 5 and fixedly connected by multiple groups of bolts 7, so that the cutting tool head 8 is fixedly installed at the extending end of the hydraulic telescopic rod 3. The telescopic movement of the hydraulic telescopic rod 3 can drive the cutting tool head 8 to move horizontally, facilitating the propulsion cutting of the outer curved surface of shaft parts.
[0027] To facilitate the replacement of the cutting tool head 8 and the contact between the mounting convex block 6 and the cooling cover 11, the cooling cover 11 can move horizontally and rotate outside the mounting kit 5 and the mounting convex block 6, as shown in the attached Figure 1 figure, attached Figure 3 figure, attached Figure 4 figure and attached Figure 5As shown, the mounting kit 5 and the mounting protrusion 6 are fitted with a cooling cover 11 on the outside. The extended end of the hydraulic telescopic rod 3 is fitted with a threaded sleeve 4. A transfer connection assembly is installed on the outside of the threaded sleeve 4. The transfer connection assembly includes a nut 9 and a connecting ring 10. The connecting ring 10 is rotatably fitted on the outside of the front end of the nut 9. The nut 9 is moved and fitted on the outside of the threaded sleeve 4 and connected by threads. By rotating the nut 9 on the outside of the threaded sleeve 4, the nut 9 drives the connecting ring 10 and the cooling cover 11 to move laterally, so that the outside of the mounting protrusion 6 contacts the inner wall of the cooling cover 11, ensuring the heat exchange effect.
[0028] The upper side of the connecting ring 10 is rotatably connected to the upper rear side of the cooling cover 11. The cooling cover 11 is rotated and moved laterally by the transfer connection assembly. When replacing the cutting head 8, the nut 9 is moved from the outside of the threaded sleeve 4 toward the cooling cover 11 so that the outside of the mounting protrusion 6 does not contact the inner wall of the cooling cover 11. The cooling cover 11 is rotated upward to remove it from the outside of the mounting kit 5 and the mounting protrusion 6, which facilitates the replacement of the cutting head 8.
[0029] To improve the cooling rate of the cutting head 8, as shown in the attached... Figure 1 and attached Figure 5 As shown, a cooling assembly is installed on the side of the cooling cover 11 near the mounting protrusion 6. The cooling assembly includes a cavity 12 inside the cooling cover 11. A water inlet pipe 13 communicating with the cavity 12 is installed on the lower part of one side wall of the cooling cover 11. A drain pipe 14 communicating with the cavity 12 is installed on the upper side of the cooling cover 11. Cooling water is circulated and transported inside the cavity 12 through the water inlet pipe 13 and the drain pipe 14 to ensure that the inside of the cooling cover 11 is at a low temperature. The cooling cover 11 cools the mounting protrusion 6. Through the thermal conductivity of the mounting protrusion 6, the cutting head 8 can be cooled.
[0030] Example 2
[0031] Based on Embodiment 1, in order to ensure the stability of the cutting head 8, as shown in the attached... Figure 2 and attached Figure 3 As shown, the propulsion assembly also includes a positioning plate 2 and a positioning ring 18. The hydraulic telescopic rod 3 is fixedly installed on the front side of the positioning plate 2. The positioning ring 18 is slidably sleeved on the outside of the extended end of the hydraulic telescopic rod 3, and a support block 19 is connected between the lower side and the upper side of the mounting plate 1. The extended end of the hydraulic telescopic rod 3 slides inside the positioning ring 18 to limit the extended end of the hydraulic telescopic rod 3 and prevent the cutting head 8 from shifting its position during cutting, thus affecting the cutting quality.
[0032] The front side of the mounting plate 1 is provided with a U-shaped groove 15 through which the cutting head 8 slides. The two side walls of the U-shaped groove 15 are provided with opposing sliding grooves 16. A U-shaped slider 17 slides between the two sets of sliding grooves 16. The top of the U-shaped slider 17 is fixedly connected to the lower side of the mounting protrusion 6 by bolts. When the hydraulic telescopic rod 3 pushes the cutting head 8 to move laterally, the mounting protrusion 6 drives the U-shaped slider 17 to slide between the two sets of sliding grooves 16. The U-shaped slider 17 limits the mounting protrusion 6, thereby preventing the cutting head 8 from shifting position during cutting and affecting the cutting quality.
