Description

Technical Field

[0001] The utility model relates to the field of metal processing, in particular to an adjustable metal cutting processing device. Background Art

[0002] Holemaking is a common process in metal cutting. Typically, due to process requirements, the diameter of the cutting tool must be gradually increased or decreased to achieve a multi-step operation from roughing to finishing. This process often requires the use of multiple tools, and each tool change requires recalibration of the machining diameter to meet the hole diameter requirements at each stage.

[0003] Traditional machining methods rely primarily on the interchange of multiple cutting tools to achieve varying aperture diameters, which not only increases machining time but also increases operational complexity. Furthermore, after changing tools, the machining diameter must be manually adjusted, which not only complicates the process but also can affect machining accuracy and quality due to errors in manual adjustments. Therefore, existing techniques for tool replacement and diameter adjustment present significant operational complexity and difficulty in achieving precision control. This is why we propose an adjustable metal cutting device. Utility Model Content

[0013] (1) In the present invention, a linear groove is provided on the tool handle so that the tool head can slide radially and be fixed by bolts, thereby realizing the relative position adjustment between the tool head and the tool handle.

In addition, this design effectively reduces the operator's repetitive work, especially when the same hole needs to be processed multiple times, the diameter requirements of different processing stages can be met only by bolt adjustment, thereby significantly improving the processing efficiency and processing quality.

[0014] (2) The push plate and the push plate work together to realize the movement of the cutter head in the linear groove, ensuring that the cutter head can be accurately positioned in the linear groove, reducing the error and inconvenience of manual adjustment, and improving operating efficiency.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0026] This embodiment provides an adjustable metal cutting processing device, such as Figures 1 to 7As shown, it includes a tool holder 1, which is assembled at the output end of the machine tool spindle. A cutter head 3 is installed in the tool holder 1. The machine tool spindle drives the cutter head 3 to rotate at high speed. The high-speed rotating cutter head 3 cuts the inside of the workpiece until the boring operation is completed. In actual applications, when the workpiece is boring, strict cutting depth control must be implemented. Especially when the workpiece is processing the same hole, due to process requirements and other reasons, multiple tools are often required to process in sequence. In this case, the processing diameter of the tool needs to be adjusted to meet the processing requirements of different stages. To this end, a linear groove 2 is opened on the end face of the tool holder 1 along its radial direction and passes through its circumferential surface. The cutter head 3 is slidably assembled in the linear groove 2 so that the relative position of the cutter head 3 and the tool holder 1 can be adjusted, that is, the cutting depth control is achieved. The end face of the tool holder 1 is also provided with a stepped groove 4 arranged parallel to the linear groove 2. A number of bolts 5 are threadedly inserted and connected on the vertical surface of the stepped groove 4, and the cutter head 3 is locked in the linear groove 2 by the bolts 5. At least two bolts 5 are provided to ensure that the cutter head 3 is in a straight line. In this embodiment, two bolts 5 are provided, one of which is provided near the linear handle 32 and the other is provided in the middle of the cutting head 31.

[0027] In order to improve the installation stability of the cutter head 3, the gap between the cutter head 3 and the linear groove 2 is very small, which leads to a large static friction between the cutter head 3 and the linear groove 2, making it difficult to manually adjust the position of the cutter head 3 in the linear groove 2. For this reason, we also slide a push plate 6 in the linear groove 2, and the push plate 6 is connected to the tail of the cutter head 3. The push plate 6 pushes the cutter head 3 to slide in the linear groove 2. Specifically, a first slide groove 21 is provided at the bottom of the linear groove 2, and the bottom of the push plate 6 is slidably assembled in the first slide groove 21. A screw rod 61 is installed in the first slide groove 21 along the length direction of the linear groove 2. The screw rod 61 is movably connected to the push plate 6 through a thread. One end of the screw rod 61 extends to the outside of the tool handle 1 and is installed with a knob. By turning the knob, the screw rod 61 is driven to rotate, and the rotating screw rod 61 causes the push plate 6 to move axially along the first slide groove 21. In this embodiment, a guide rod 62 is fixedly mounted in the first slide groove 21 along the length of the linear groove 2. The guide rod 62 movably penetrates the push plate 6 and limits the rotation of the push plate 6 by the guiding action of the guide rod 62, allowing the push plate 6 to move axially along the screw rod 61. It should be noted that when adjusting the position of the cutter head 3 in the linear groove 2, the bolt 5 must first be loosened.

[0028] On the basis of the above scheme, in view of the unique structure of the cutter head 3, a support plate 64 is slidably mounted in the linear groove 2. The support plate 64 cooperates with the push plate 6 to adjust the position of the cutter head 3. Specifically, the cutter head 3 is composed of a cutting head 31 and a linear handle 32. The cutting head 31 is slidably mounted in the linear groove 2. The linear handle 32 is located on the outside of the linear groove 2. A stepped opening 33 is formed between the linear handle 32 and the cutting head 31. The push plate 6 is located on one side of the stepped opening 33 and is mounted with a support plate 64 through a connecting rod 63. The support plate 64 is slidably mounted in the linear groove 2, and the other end of the support plate 64 contacts the stepped opening 33. When the push plate 6 moves, the support plate 64 moves synchronously and applies a thrust to the stepped opening 33, causing the cutter head 3 to move in the linear groove 2. In this embodiment, in order to remind the operator to install the stepped opening 33 on the side corresponding to the support plate 64, an indicator arrow 12 is installed on the end face of the tool handle 1 to indicate the installation direction of the cutter head 3.

[0029] When the cutter head 3 moves along the linear groove 2 in the direction away from the tool handle 1, the distance between the step opening 33 and the tool handle 1 increases. As the cutter head 3 moves away from the tool handle 1, the center of gravity will be biased toward the head area of ​​the cutter head 3. This center of gravity shift will increase the vibration during processing, making the force on the cutter head 3 uneven, affecting the processing accuracy and surface quality. Because, we have a support rod 65 connected to the end face of the support plate 64 away from the cutter head 3, and the other end of the support rod 65 is connected to the slider 66. The side wall of the linear groove 2 is opened at the position corresponding to the support rod 65. There is an opening 22, and a second slot 23 is provided in the opening 22 at a position corresponding to the slider 66. The slider 66 slides into the second slot 23. The support rod 65, the cutter head 3, and the second slot 23 form a triangular structure. This triangular structure can disperse and support the force exerted on the cutter head 3, making the force more uniform during the cutting process, thereby reducing vibration. As the cutter head gradually moves away from the tool handle, the angle between the support rod 65 and the cutter head 3 increases, which helps to strengthen the support effect and further improve the stability of the cutter head 3 at a longer extension length. At the same time, the rigid design of the triangular structure can also reduce deformation during processing, ensuring processing accuracy and surface quality.

[0030] In addition, in order to facilitate the operator to quickly know the relative distance between the cutter head 3 and the handle 1, we install a scale line 11 on the handle 1. By observing the numbers on the scale line 11, the moving distance of the cutter head 3 can be quickly known.
