Description

Technical Field

[0001] The present invention relates to the technical field of turning tools, and more particularly to a multi-faceted turning tool for a numerically controlled machine tool. Background Art

[0002] Multi-surface turning tools for CNC machine tools are specialized cutting tools suitable for CNC machine tools. They are designed specifically for turning multiple surfaces of workpieces (such as outer circles, end faces, step surfaces, grooves, etc.). Their core feature is that they meet the multi-process processing requirements of complex workpieces under one clamping through integrated structure and functional design, thereby improving processing efficiency and precision.

[0003] The current tool cooling system is inefficient and cannot meet the cooling requirements of the blade under high-speed and high-feed cutting conditions. Ordinary cooling methods rely only on a single nozzle or a simple spray structure. The coolant cannot accurately and fully cover all cutting areas of the blade, especially the high-temperature areas where the blade contacts the workpiece, resulting in frequent local overheating. This not only accelerates the wear of the blade and significantly shortens its service life, but frequent blade replacement also increases downtime and reduces production efficiency. At the same time, the high temperature generated by overheating can easily cause defects such as burns and deformation on the workpiece surface, seriously affecting processing accuracy and surface quality.

The stabilizing screw 5 adjusts the degree of pressure on the tool rod 4 by tightening the force. The lower ends of several stabilizing screws 5 are respectively in contact with the lower ends of the tool rod 4 to fix the tool rod 4 from different directions. The blade body 7 is located inside the mounting groove to ensure that the blade is accurately positioned during processing. The blade body 7 directly participates in the cutting of the workpiece. The direct injection mechanism can cool the cutting part of the blade in a targeted manner. The lower flow channel 34 is one of the paths for the coolant to circulate.

The supporting platform 35 is in an L-shaped structure. This structure can better fit the bottom of the circular frame 14 and enhance the stability of the support.

[0021] like Figure 5 and Figure 6 As shown: the direct injection mechanism can directly spray the coolant onto the blade body 7. The direct injection mechanism includes a stabilizing block 8, which is rotatably connected to one side of the upper end of the cutter head 6 through a rotating shaft. The lower end of the stabilizing block 8 contacts one side of the upper end of the blade body 7.

[0022] like Figure 3-Figure 8As shown: the outer wall of the tool rod 4 is connected to a cooling mechanism, which can spray cooling on multiple sides of the blade body 7. The cooling mechanism includes a circular frame 14. The middle part of the upper end and the upper parts of both sides of the circular frame 14 are connected to cooling nozzles 22. Both sides of the multiple cooling nozzles 22 are rotatably connected to support rods 21, wherein the lower ends of two support rods 21 are connected to the middle part of the upper end of the circular frame 14, and one end of the other several support rods 21 are respectively connected to the upper parts of both sides of the circular frame 14. An adjustment mechanism is connected inside the cooling mechanism, one side of the lower end of the multiple cooling nozzles 22 is connected to a fixing pipe 23, and the upper part of one side of the circular frame 14 is connected to a positioning plate 15, the lower end of the positioning plate 15 is connected to one side of the upper end of the tool rod 4, and both sides of the upper end of the positioning plate 15 are connected to the tool rod through positioning bolts 16 4 connection, an opening is provided at the lower part of the inner wall of the circular frame 14, and a liquid collecting frame 17 is connected to the lower part of both sides of the inner wall of the circular frame 14. Both sides of the inner wall of the liquid collecting frame 17 are arranged in an inclined shape, and a liquid pump 18 is connected to one side of the lower end of the inner wall of the liquid collecting frame 17. The output end of the liquid pump 18 is connected to an infusion tube 19, and one end of the infusion tube 19 extends through one side of the liquid collecting frame 17. The shape of the infusion tube 19 is an inverted L-shaped structure, and the shape of the infusion tube 19 is adapted to the shape of the inner wall of the circular frame 14. Connecting tubes 20 are connected to the upper part and the middle part of the upper end of the infusion tube 19 on both sides, and one end of the multiple connecting tubes 20 extends through the outside of the circular frame 14. One end of the multiple connecting tubes 20 is connected to a hose 24, and one end of the multiple hoses 24 is respectively connected to one end of multiple fixed tubes 23; The cooling mechanism can expand the cooling range and avoid local overheating of the blade body 7. The circular frame 14 surrounds the outside of the tool rod 4 and provides a mounting carrier for components such as the cooling nozzle 22. Multiple cooling nozzles 22 cool the blade body 7 from different angles. The support rod 21 provides support and rotation fulcrum for the cooling nozzle 22, which enables the cooling nozzle 22 to be stably installed and flexibly adjusted in angle. The adjustment mechanism is used to control the angle change of the cooling nozzle 22. The fixed pipe 23, the hose 24 and the connecting pipe 20 are used to transport the coolant to the cooling nozzle 22. At the same time, the circular frame 14 is firmly fixed to the tool rod 4 through the positioning plate 15 and the positioning bolt 16 to prevent The circular frame 14 moves, and the opening allows the coolant to enter the liquid collecting frame 17. The liquid collecting frame 17 is used to collect the coolant flowing in from the lower flow channel 34 to facilitate the gathering of the coolant. The liquid pump 18 provides power for the transportation of the coolant inside the liquid collecting frame 17. The infusion pipe 19 transports the coolant pumped out by the liquid pump 18 to the inside of each connecting pipe 20. The infusion pipe 19 is adapted to the internal space of the circular frame 14, which is convenient for installation and arrangement. The connecting pipe 20 diverts the coolant in the infusion pipe to the inside of each hose 24. The hose 24 has a certain degree of flexibility, which is convenient for cooperating with the angle adjustment of the cooling nozzle 22, so that the coolant can be smoothly transported from the connecting pipe 20 to the inside of the cooling nozzle 22.

[0023] like Figure 9 and Figure 10As shown: the adjustment mechanism includes a rotating rod 25, the number of the rotating rod 25 is four groups, one end of the multiple rotating rods 25 is respectively connected to the inner wall of the circular frame 14, the outer wall of the multiple rotating rods 25 is connected to a synchronous wheel 26, the outer wall of the multiple synchronous wheels 26 is connected to a synchronous belt 27, one end of one rotating rod 25 is connected to a drive motor 28, one end of the other rotating rods 25 is connected to the inner wall of the circular frame 14, one end of the drive motor 28 is connected to the inner wall of the circular frame 14, and the middle part of the upper end and the upper part of both sides of the synchronous belt 27 are connected to the moving block 2 9. The outer wall of the circular frame 14 is provided with movable grooves 30 corresponding to the multiple movable blocks 29. The multiple movable blocks 29 are respectively located in the multiple movable grooves 30 and slide. The multiple movable blocks 29 are connected to an adjustment plate 31 at one end away from the synchronous belt 27. An adjustment groove 32 is provided on one side of the adjustment plate 31. The adjustment groove 32 is in the shape of a semi-arc structure. An adjustment rod 33 is slidably connected to the middle of the inner wall of the multiple adjustment grooves 32. One end of the adjustment rod 33 is in the shape of a T-shaped structure. One end of the multiple adjustment rods 33 is respectively connected to the middle of one end of the multiple cooling nozzles 22. The stability of the rotation of the synchronous wheel 26 and the synchronous belt 27 can be improved by using multiple rotating rods 25. The rotating rod 25 provides support and power transmission for the rotation of the synchronous wheel 26. The cooperation between the synchronous wheel 26 and the synchronous belt 27 realizes power transmission and direction conversion. The movement of the synchronous belt 27 drives the moving block 29 to move synchronously. The moving groove 30 provides guidance and restriction for the movement of the moving block 29 to ensure that the moving block 29 can move smoothly. The movement of the moving block 29 drives the adjustment plate 31 to move synchronously. The adjustment groove 32 provides a trajectory for the movement of the adjustment rod 33. The T-shaped structure of the adjustment rod 33 can prevent the adjustment rod 33 from falling off from the adjustment groove 32. When the adjustment plate 31 moves, the adjustment rod 33 slides in the adjustment groove 32, thereby driving the cooling nozzle 22 to adjust the angle, thereby realizing cooling of multiple sides of the blade.

[0024] Working principle: During installation, the blade body 7 is fixed inside the installation slot by means of the mounting bolts, and the stabilizing block 8 is moved so that its lower end is pressed against one side of the upper end of the blade body 7 to ensure the stability of the blade body 7, and the straight-injection nozzle 13 of the stabilizing block 8 corresponds to the position of the blade body 7; then the circular frame 14 is sleeved on the outer wall of the tool rod 4, and the circular frame 14 is fixed to the outer wall of the tool rod 4 by means of the positioning plate 15 and two positioning bolts 16. At this time, the lower side of the circular frame 14 is aligned with the lower flow channel 34 of the tool rod 4; after the tool is installed, it is placed on one side of the upper end of the lower tool holder 2, and the circular frame 14 is placed on the upper end of the supporting platform 35. The tool rod 4 is pressed against by a plurality of stabilizing screws 5, and the tool can be fixed above the lower tool holder 2; During operation, the liquid inlet pipe 10 at one end of the tool bar 4 is connected to the coolant delivery pipe. The position of the movable seat 1 is adjusted so that one end of the blade body 7 contacts the workpiece body, and the workpiece body is turned. During the machining process, the coolant is transported to the interior of the liquid inlet pipe 10 through the coolant delivery pipe, and then passes through the cooling channel 9, the delivery channel 11, and the upper channel 12 to enter the direct spray nozzle 13. The direct spray nozzle 13 sprays the end of the blade body 7. After the blade body 7 contacts the workpiece for machining, the end of the blade body 7 is directly cooled by the direct spray to reduce the temperature at the end of the blade body 7. The cooling mechanism can cool down multiple parts of the outer wall of the blade body 7: part of the coolant inside the cooling channel 9 flows into the liquid collecting frame 17 through the lower flow channel 34, and the liquid pump 18 inside the liquid collecting frame 17 is started to transport the coolant to the liquid infusion pipe 19, and enters the multiple cooling nozzles 22 through multiple connecting pipes 20, hoses 24 and fixed pipes 23 respectively. The multiple cooling nozzles 22 spray the coolant onto multiple parts of the outer wall of the blade body 7; when the driving motor 28 is working, it drives the rotating rod 25 and the synchronous wheel 26 at its output end to rotate, and then drives the synchronous belt 27 to transmit. During the transmission process of the synchronous belt 27, it drives the multiple moving blocks 29 and the multiple adjustment plates 31 to move to one side, so that the adjustment rod 33 is adjusted in the adjustment position. The slot 32 slides inside; because the adjustment slot 32 is a semi-arc structure, the position of the adjustment rod 33 inside the adjustment slot 32 changes, and pushing the adjustment rod 33 downward can drive one end of the cooling nozzle 22 to rotate downward. The cooling nozzle 22 is located between the two support rods 21 and rotates, so that the angle of the cooling nozzle 22 is slowly adjusted by 30 degrees to achieve spraying on multiple parts of the outer wall of the blade body 7; after adjusting to 30 degrees, the drive motor 28 is reversed, driving the rotating rod 25, the synchronous wheel 26 and the synchronous belt 27 to move in the opposite direction, so that the multiple moving blocks 29 and the adjustment plate 31 are reset, thereby adjusting the angle of the cooling nozzle 22 back and forth, spraying multiple parts of the outer wall of the blade body 7, and avoiding residual waste chips on the outer wall of the blade body 7.
