Description

Technical Field

[0001] This utility model belongs to the field of machining tool technology, specifically relating to a CNC cutting tool head for lathes. Background Technology

[0002] Cutting tools are tools used for cutting processes in mechanical manufacturing. They are divided into metal cutting tools, woodworking tools, and mining tools, etc. Machining tools are mainly used for metal cutting, and common types include turning tools, milling cutters, drills, boring tools, and reamers.

[0003] The cutting tool disc of the machine tool is installed at the output end of the machine tool through a connecting mechanism. The output end is connected to the drive mechanism of the machine tool. The drive mechanism drives the output end to rotate, which in turn drives the cutting tool disc inside the cutting tool disc mechanism to rotate. Then, the moving device on the machine tool drives the cutting tool disc to move closer to the workpiece, so that the rotating cutting tool disc can perform cutting on the workpiece.

[0004] Currently, when milling the inner surface of tubular workpieces, the same cutter head can only be used for tubular workpieces of the same specification, which has low adaptability.

[0005] A search revealed that Chinese utility model patent CN222114355U, authorized by the prior art, discloses "a cutting tool disc for a machine tool", which includes a disc body. A disc shaft is fixedly connected to one side of the disc body, and four sliding grooves are opened on the other side of the disc body. Each sliding groove is provided with a moving structure. This utility model uses a sliding slider, a first countersunk threaded rod, a moving column, and a first countersunk positioning bolt, etc. The first countersunk threaded rod drives the moving column to move outward through the sliding slider connected by the thread.

[0006] While existing cutting head technologies, including those described above, can adjust the position of the cutting head, they cannot be expanded to accommodate different cutting heads according to actual machining needs. This necessitates replacing the entire cutting head or its related accessories, resulting in significant limitations in their use.

[0007] To solve the above problems, this utility model proposes a CNC cutting tool head for lathes. Utility Model Content

The adjustment mechanism is used to adjust the initial position of the first tool holders. A tool head slot for mounting the tool heads is machined on the first tool holders. The tool head also includes:

[0010] The second tool holder has multiple second mounting slots that are equally spaced along the circumferential direction on the outer wall of the cutter head body, and the second tool holder is fixed in the second mounting slots.

[0011] The No. 3 countersunk screw has a threaded hole machined on the cutter head body and a countersunk hole machined on the No. 2 tool holder. The No. 3 countersunk screw passes through the countersunk hole and is screwed into the threaded hole by thread engagement.

[0012] As a preferred embodiment of this utility model, the outer wall of the second tool holder abuts against the inner wall of the second mounting groove.

[0013] As a preferred embodiment of this utility model, the No. 2 tool holder is fixed in the No. 2 mounting groove by two symmetrically distributed No. 3 countersunk screws.

With the above scheme, during use, the cutter head body 1 is fixed on the output shaft of the CNC lathe, and the output shaft of the CNC lathe controls the rotation and movement of the cutter head body 1 to achieve cutting operations. When necessary, the second tool holder 8 can be moved... The handle 8 is placed in the second mounting slot 13, and the third countersunk screw 9 passes through the countersunk hole 81 and is screwed into the threaded hole 14 for locking. Different cutting heads 3 are fixed on the second tool holder 8 for machining operations. In addition, the initial position of the first tool holder 2 can be adjusted according to the inner diameter of the tubular workpiece by adjusting the adjustment mechanism 5. This utility model, by reserving the second mounting slot 13 on the cutter head body 1 and adding the second tool holder 8, facilitates the expansion of different cutting heads 3 according to different machining needs, without the need to replace the entire cutter head body 1 or its related accessories, making it more convenient to use and improving machining efficiency.

[0037] Preferably, by Figure 1 and Figure 3 As shown in this embodiment, the outer wall of the second tool holder 8 abuts against the inner wall of the second mounting groove 13. With the above solution, this close fit has high stability during use, ensuring the stability of the installation of the second tool holder 8 and preventing the second tool holder 8 from shaking during operation.

[0038] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, the No. 2 tool holder 8 is fixed in the No. 2 mounting groove 13 by two symmetrically distributed No. 3 countersunk screws 9. With the above solution, the two No. 3 countersunk screws 9 will generate a higher locking force during use, ensuring the stability of the No. 2 tool holder 8 installation.

[0039] Optionally, by Figure 1 and Figure 2 As shown, in this embodiment, the adjustment mechanism 5 includes: a guide slider 51, a threaded screw 52, ​​and a hexagonal rotating block 53. The guide slider 51 is fixed to the bottom surface of the first tool holder 2, and a guide groove 12 for the guide slider 51 to be embedded is machined on the cutter body 1. The threaded screw 52 is rotatably installed in the guide groove 12, and the threaded screw 52 passes through the guide slider 51 and is connected to the guide slider 51 by thread engagement. The hexagonal rotating block 53 is fixed to one end of the threaded screw 52. With the above scheme, when in use, the threaded screw 52 is rotated by the hexagonal rotating block 53. Under the thread engagement, the guide slider 51 drives the first tool holder 2 to move along the guide groove 12 to adjust the initial position of the cutter head 3.

[0040] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, the outer wall of the first tool holder 2 abuts against the inner wall of the first mounting groove 11. With the above solution, this close fit has high stability during use, ensuring the stability of the installation of the first tool holder 2 and preventing the first tool holder 2 from shaking during operation.

[0041] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the outer wall of the guide slider 51 abuts against the inner wall of the guide groove 12. With the above solution, this close fit has high stability during use, which can further improve the stability of the first tool holder 2.

[0042] Preferably, by Figure 1 and Figure 4As shown, this embodiment also includes: a pressure plate 6 and a No. 4 countersunk screw 10. The pressure plate 6 is fixed to the top of the cutter head body 1 using two symmetrically distributed No. 2 countersunk screws 7, and spans the No. 1 mounting groove 11.
