Description

Technical Field

[0001] This utility model relates to the field of machining tool technology, specifically a precision ultra-narrow double right-angle profile forming tool. Background Technology

[0002] Contour machining refers to cutting a workpiece with the peripheral side cutting edge of a cylindrical milling cutter to form a contour of a certain size and shape. Milling the outer contour of a workpiece typically uses a high-speed steel or carbide end mill. The entry point is chosen outside the workpiece body, and the position and direction of the entry point should be as close as possible to the extension of the tangential direction of the workpiece contour. Care should be taken to avoid the fixture during the entry and exit of the cutter, and to avoid hitting areas on the workpiece that should not be cut. When exiting the workpiece, it should still be cut as close as possible to the extension of the tangential direction of the workpiece contour to ensure stable tool force and to minimize obvious seams at the transition points of the workpiece contour.

[0003] Currently, for arbitrarily narrow double 90-degree right angles, the common practice is to use two tools to machine the shape using carbide for 90° right angles. The tool manufacturing is relatively conventional, and during the tooling process, it is difficult to guarantee the product's dimensional accuracy, which is prone to exceeding tolerances. It is mainly necessary to perform tool setting twice to meet the product requirements. The tool is only 0.35mm in diameter, and the grinding wheel cannot go down to the narrow position on the same tooth, so it cannot be machined. Therefore, we propose a precision ultra-narrow double right angle contour forming tool. Utility Model Content

[0004] The purpose of this invention is to provide a precision ultra-narrow double right-angle profile forming tool.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision ultra-narrow double right-angle profile forming knife, comprising a blade body, a blade neck fixedly connected to the left side of the blade body, a blade head fixedly connected to the left side of the blade neck, multiple through slots formed around the outer periphery of the blade head, multiple locking blocks provided on the inner wall of the blade head, a first blade fixedly connected to the side of the locking block away from the blade head, connecting strips fixedly connected around the outer periphery of the blade body, blade neck, and blade head, a third blade fixedly connected to the left end of the connecting strip near the blade head, and multiple second blades provided on the right side of the third blade.

[0006] As a further embodiment of this utility model: a shell is fixedly connected to the outer right side of the blade, and an internal thread is provided on the inner right side of the shell.

[0007] As a further embodiment of this utility model: a handle is provided on the right side of the blade, and an external thread is provided on the left side of the outer wall of the handle, and the handle is located inside the right side of the outer casing.

[0008] As a further embodiment of this utility model: a mounting base is provided at the right end of the knife handle, and the interior of the left side of the outer casing is smooth.

[0009] As a further embodiment of this utility model: the mounting base is provided with a cooling main pipe, and multiple cooling branch pipes are fixedly connected to the center of the left end of the cooling main pipe through the handle, the blade, and the neck in sequence. The multiple cooling branch pipes are fixedly connected to the outer wall of the left end of the cooling main pipe at equal intervals.

[0010] As a further embodiment of this utility model: the cooling branch pipe is provided with multiple cooling ports on the side near the blade, and the cooling ports are connected to the cooling branch pipe and the cooling main pipe.

[0011] As a further embodiment of this utility model, a chip removal groove is provided between two adjacent connecting strips.

[0012] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0013] 1. This utility model is formed by the combination of multiple teeth of blade one, blade two and blade three, which has the advantage of ultra-high precision. At the same time, the processing is stable. This structure can be used at any 90° right angle to meet the product size requirements. Moreover, the gap between the through groove and the two connecting strips ensures sufficient chip removal space and prevents chip squeezing.

[0014] 2. This utility model, by rotating the outer shell, allows the internal thread on the outer shell to engage with the external thread on the tool holder, causing the tool holder to move outward during the rotation of the outer shell, thereby increasing the distance between the tool holder and the tool body, thus achieving the effect of extending the length and making it easier to adapt to different machining depths; in addition, cutting fluid is connected to the external cooling main pipe and enters the cooling port through the cooling branch pipe, and is sprayed inside the tool head, thereby achieving the effect of cooling the cutting edge and flushing away waste chips.

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0022] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Please see the appendix Figure 1 - Appendix Figure 4 This utility model discloses a precision ultra-narrow double right-angle profile forming knife, including a blade body 1, a blade neck 5 fixedly connected to the left side of the blade body 1, a blade head 6 fixedly connected to the left side of the blade neck 5, multiple through slots 10 opened around the outer perimeter of the blade head 6, multiple locking blocks 11 provided on the inner wall of the blade head 6, a first blade 12 fixedly connected to the side of the locking block 11 away from the blade head 6, a connecting strip 15 fixedly connected around the outer perimeter of the blade body 1, the blade neck 5 and the blade head 6, a third blade 14 fixedly connected to the left end of the connecting strip 15 near the blade head 6, and multiple second blades 13 provided on the right side of the third blade 14.

[0024] Specifically, the multi-tooth combination of blade 12, blade 23 and blade 314 provides the advantage of ultra-high precision and stable processing. This structure can be used at any 90° right angle to meet product size requirements, and the gap between the through groove 10 and the two connecting strips 15 ensures sufficient chip removal space and prevents chip compression.

[0025] In the first embodiment, a housing 3 is fixedly connected to the outer right side of the blade 1. An internal thread is provided on the right side of the inner side of the housing 3. A handle 4 is provided on the right side of the blade 1. An external thread is provided on the left side of the outer wall of the handle 4. The handle 4 is located on the right side of the inner side of the housing 3.

[0026] Specifically, by rotating the outer shell 3, the internal threads on the outer shell 3 and the external threads on the tool holder 4 engage, causing the tool holder 4 to move outward during the rotation of the outer shell 3, thereby increasing the distance between the tool holder 4 and the tool body 1, and achieving the required machining depth.

[0027] In embodiment 2, a mounting base 2 is provided at the right end of the handle 4, and the left side interior of the outer shell 3 is smooth. A cooling main pipe 7 is provided inside the mounting base 2. Multiple cooling branch pipes 8 are fixedly connected to the center of the handle 4, the blade 1, and the neck 5 in sequence at the left end of the cooling main pipe 7. The multiple cooling branch pipes 8 are fixedly connected to the outer wall of the left end of the cooling main pipe 7 at equal intervals. Multiple cooling ports 9 are provided on the side of the cooling branch pipe 8 near the blade 12. The cooling ports 9 are connected to the cooling branch pipes 8 and the cooling main pipe 7.

[0028] Specifically, the tool holder 4 is fixedly connected to the machine tool spindle through the mounting base 2. Then, the cooling main pipe 7 is connected to the external cutting fluid, which is sprayed onto the cutting edge inside the tool head 6 through the cooling branch pipe 8 and the cooling port 9. This facilitates the cooling of the cutting edge and flushing away of waste chips during processing, greatly reducing the cutting edge damage rate and extending the service life of the cutting edge.

[0029] Working principle:

[0030] First, the tool holder 4 is fixedly connected to the machine tool spindle via the mounting base 2. Then, the cooling main pipe 7 is connected to external cutting fluid, which is sprayed onto the cutting edge inside the tool head 6 through the cooling branch pipe 8 and cooling port 9. This facilitates the cooling of the cutting edge and the removal of waste chips during machining, greatly reducing the damage rate of the cutting edge and extending its service life. Subsequently, by rotating the outer shell 3, the internal thread on the outer shell 3 and the external thread on the tool holder 4 engage, causing the tool holder 4 to move outward during the rotation of the outer shell 3, thereby increasing the distance between the tool holder 4 and the tool body 1 to achieve the required machining depth. The multi-tooth combination of cutting edge 12, cutting edge 23 and cutting edge 34 provides the advantage of ultra-high precision and stable machining. This structure can be used at any 90° right angle to meet product size requirements. Furthermore, the gap between the through groove 10 and the two connecting strips 15 ensures sufficient chip removal space and prevents chip crowding. At this point, the entire workflow is complete.
