Description

Technical Field

[0001] This utility model relates to the field of T-shaped cutting tool technology, specifically an ultra-thin inlaid T-shaped cutting tool disc. Background Technology

[0002] In the machining industry, T-shaped cutter heads are often used for machining some undercut positions or small grooves. Among the commonly used T-shaped cutter head types, there are roughly two types: one is generally called blade type, and the other is saw blade type.

[0003] Blade-type installation requires a fastening screw between the blade and the blade body. Therefore, blade-type T-shaped cutter heads are relatively thick, typically over 6mm, to accommodate this installation method. This makes blade-type T-shaped cutter heads unsuitable for ultra-thin grooves less than 6mm thick. In such cases, a saw blade-type T-shaped cutter head is chosen. Saw blade-type T-shaped cutter heads often have two types of cutting edges: one is made entirely of tungsten steel, which requires re-sharpening of all teeth on the cutting edge after wear during use.

[0004] Furthermore, the entire saw blade is made of tungsten carbide, which determines the high price of T-shaped saw blades. Another type of T-shaped saw blade has a blade body made of ordinary alloy steel, with only the cutting edge welded with tungsten carbide. This type of saw blade is generally cheaper, but the cutting edge will wear down with use, requiring resharpening or replacement of damaged edges. Thus, we find that blade-type T-shaped saw blades, which allow for easy blade replacement, cannot machine tiny, ultra-thin T-grooves. Saw blade-type T-shaped saw blades, which can machine ultra-thin grooves, cannot easily and quickly repair worn cutting edges, and are also generally expensive.

[0005] To address the aforementioned issues, an ultra-thin inlaid blade was designed. Instead of being fixed by welding, the blade is installed by creating a blade inlay slot in the blade body. This facilitates the installation and removal of worn blades, achieving the desired tool performance. It can process ultra-thin grooves and allows for easy replacement of worn blade edges.

[0029] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0030] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0031] As attached Figure 1 and Figure 2 The ultra-thin inlaid T-shaped cutter head shown includes: a cutter handle 1 and a wrench 3. A positioning post 11 is fixedly connected to one end of the cutter handle 1. A connecting seat 12 is sleeved on the outside of the positioning post 11. A cutter head 13 is provided at one end of the connecting seat 12. Multiple blades 14 are provided around the cutter head 13. An installation mechanism is provided on the cutter head 13 for installing the blades 14.

[0032] Wherein: the handle 1 serves as the mounting body, and the connecting seat 12 is positioned by the positioning pin 11, so that the connecting seat 12 is precisely assembled onto the handle 1. Then, the cutter disc 13 is assembled onto the connecting seat 12. Subsequently, the blade 14 is installed into the mounting mechanism by the wrench 3. The blade 14 is installed and fixed by the mounting mechanism. The blade 14 can be fixed without the use of screws, which can reduce the thickness of the cutter disc 13 and achieve the purpose of ultra-thin.

[0033] As attached Figure 3 and Figure 7 As shown, the mounting mechanism includes: a blade mounting groove 2, an edge 21, a groove 22, an elastic cutting groove 23, and a protrusion 24. The blade mounting groove 2 is provided around the blade disc 13. The blade mounting groove 2 is provided with triangular edge 21 on both sides. The blade 14 is provided with groove 22 on both sides that are adapted to the edge 21. The groove 22 is engaged between the edge 21. An elastic cutting groove 23 is provided on one side of the top of the blade mounting groove 2. The blade 14 is provided with a protrusion 24 on one side of the top and the bottom. The two protrusions 24 extend into the elastic cutting groove 23.

[0034] In the process of installing the blade 14, the bottom end of the blade 14 is first precisely inserted into the blade mounting groove 2, so that the ridge grooves 22 on both sides of the blade 14 correspond accurately with the ridge edges 21 on both sides of the blade mounting groove 2 and are locked in. This structural design can effectively limit the displacement of the blade 14 along the axial direction of the cutter head 13 and provide stable lateral positioning for the blade 14.

[0035] Meanwhile, during the insertion and installation of the blade 14, the top and bottom protrusions 24 are naturally pushed into the two elastic cutting grooves 23. This design allows the blade 14 to obtain good spring pressure performance during insertion and installation. The force generated by the elastic structure firmly fixes the blade 14, thus eliminating the need to rely on tightening screws as in traditional installation methods. This simplifies the installation process and ensures the stability of the blade 14 during operation.

[0036] As attached Figure 4 , Figure 5 and Figure 6 As shown, a positioning rod 31 and a pushing rod 32 are fixedly connected to one side of the wrench 3. The positioning rod 31 and the pushing rod 32 are staggered. A positioning round hole 33 for use with the positioning rod 31 is opened at the position of the elastic cutting groove 23 near the top of the cutter head 13. A disassembly groove 34 is opened at the bottom of the blade mounting groove 2.

[0037] Specifically: When inserting the blade 14, the positioning rod 31 on one side of the wrench 3 is inserted into the positioning hole 33 at the corresponding blade 14. Then, the wrench 3 is rotated to the side of the blade 14. The wrench 3 deflects around the positioning hole 33, causing the pushing rod 32 to press against the top of the blade 14 and push the blade 14 into the blade mounting groove 2, so that the blade 14 is installed in place.

[0038] When disassembling the blade 14, insert the push rod 32 into the disassembly groove 34 and insert the positioning rod 31 into the positioning hole 33 at the corresponding blade 14. Rotate the wrench 3 towards the positioning hole 33 so that the wrench 3 deflects around the positioning hole 33 as the center, so that the push rod 32 moves along the disassembly groove 34 to pry the blade 14 out of the blade mounting groove 2, thereby completing the disassembly of the blade 14.

[0039] This design allows the thickness of the blade 14 to be reduced to 2mm, enabling the processing of ultra-thin grooves. Furthermore, the installation method of the blade 14 is changed, abandoning the previous screw-fixed installation method and using an inlaid tenon-and-mortise type blade 14 installation method. This gives it both the advantage of the blade-type T-shaped cutter head, which allows for easy blade replacement, and the advantage of the saw blade type cutter head, which can process ultra-thin grooves, thus increasing the flexibility of using T-shaped cutters.

[0040] As attached Figure 1 and Figure 2 As shown, a square hole 4 is provided at the axis of the cutter head 13. A square block 41 is fixedly connected to one end of the connecting seat 12. The square hole 4 is fitted onto the square block 41. Umbrella-shaped mounting cone holes 42 are respectively provided on the cutter head 13 near the four sides of the square hole 4. A screw hole a43 corresponding to the mounting cone hole 42 is provided at one end of the connecting seat 12. Umbrella screws 44 are provided inside the mounting cone holes 42. One end of the umbrella screw 44 passes through the mounting cone hole 42 and extends into the screw hole a43.

[0041] Specifically: When installing the cutter head 13, the square hole 4 on the cutter head 13 is fitted into the square block 41 on the connecting seat 12. The quadrilateral structure allows the connecting seat 12 to drive the cutter head 13 to rotate, and at the same time, it can also position the cutter head 13 so that the four mounting cone holes 42 are aligned with the four screw holes a43. Then, the umbrella screws 44 are inserted into the mounting cone holes 42 respectively, and then the umbrella screws 44 are screwed into the screw holes a43 using an Allen wrench, thereby installing and fixing the cutter head 13 onto the connecting seat 12.

[0042] As attached Figures 1 to 5 As shown, a countersunk screw hole 5 is provided at the center of the square block 41, and a screw hole b51 is provided at the center of the positioning post 11. A fastening screw 53 is provided in the countersunk screw hole 5. One end of the fastening screw 53 passes through the countersunk screw hole 5 and extends into the screw hole b52. Two symmetrically distributed keyways 6 are provided at the other end of the connecting seat 12. A positioning key 61 corresponding to the two keyways 6 is fixedly installed at one end of the tool holder 1. The positioning key 61 extends into the corresponding keyway 6.

[0043] Specifically: When installing the connecting seat 12, the connecting seat 12 is fitted onto the positioning post 11. During the fitting, ensure that the two keyways 6 are aligned with the two positioning keys 61, so that the keyways 6 are fitted onto the positioning keys 61. This facilitates the rotation and force application of the tool during use. Then, the fastening screw 53 is inserted into the countersunk screw hole 5, and then the fastening screw 53 is screwed into the screw hole b51 using an Allen wrench. This connects and fixes the connecting seat 12 to the tool holder 1.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
