[0002] A right-angle milling head is a widely used machine tool accessory in the field of machining. Mounted on the end face of the machine tool spindle or on the ram, the right-angle milling head's spindle receives power from the machine tool spindle via a transmission system, causing the spindle to rotate the cutting tool. During machining, the machine tool's worktable or cutting tool moves along a set trajectory, and the cutting tool performs cutting operations on the workpiece. By adjusting the angle and position of the right-angle milling head, machining of different parts of the workpiece and at different angles can be achieved.

[0003] Currently, specialized clamping fixtures are used. These fixtures require precise alignment with the reference surface of the cutting tool, and the clamping force needs to be adjusted via multiple screws or knobs. For example, when regrinding some complex form milling cutters, the clamping process may involve positioning and clamping operations in multiple directions. This series of complex steps consumes a lot of time, thereby reducing the overall efficiency of regrinding. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Reference Figure 1-4 A right-angle milling head grinding device includes a body 1, an adjustment plate 2 fixedly connected to the top of the body 1, a grinding machine 3 fixedly connected to the adjustment plate 2, a fixing plate 4 fixedly connected to the top of the body 1, a sliding plate 5 slidably connected to the fixing plate 4, and two symmetrically arranged positioning blocks 20 fixedly connected to the top of the sliding plate 5 for positioning the tool during the pushing process and improving efficiency.

[0023] This utility model mainly includes a robust body 1, which is made of high-strength steel and has good stability and load-bearing capacity. It can effectively support the operation of the entire equipment and ensure that the grinding accuracy will not be affected by vibration or other factors during the grinding process.

[0024] The top of the machine body 1 is fixedly connected to the adjustment plate 2 via a precise welding process. The surface of the adjustment plate 2 is finely polished, resulting in extremely high flatness, providing a stable and precise platform for the installation of the regrinding machine 3. The regrinding machine 3, firmly fixed to the adjustment plate 2, is the core regrinding component of the equipment. It features high speed and high precision, enabling efficient and accurate regrinding of various tools. The regrinding machine 3 is made of special abrasive and can be replaced according to different tool materials and regrinding requirements to meet diverse processing needs.

[0025] Meanwhile, a fixing plate 4 is tightly fixed to the top of the body 1 with bolts. The fixing plate 4 is made of high-quality aluminum alloy and has been precision machined, achieving extremely high standards of straightness and parallelism on its surface. A high-precision linear guide rail is installed on the fixing plate 4, and the sliding plate 5 achieves a smooth sliding connection with this linear guide rail via a slider. This design allows the sliding plate 5 to maintain extremely high stability and accuracy during movement.

[0026] Two symmetrically arranged positioning blocks 20 are welded to the top of the sliding plate 5. They can also be quickly fixed using bolts. The positioning blocks 20 are made of high-hardness, wear-resistant alloy steel, and their surfaces in contact with the cutting tool undergo special quenching treatment to improve their wear resistance. During actual tool regrinding, when tool positioning is required, the operator places the tool on the sliding plate 5 and pushes the sliding plate 5 to ensure that both sides of the tool are tightly fitted against the two symmetrically arranged positioning blocks 20. Due to the symmetrical arrangement of the positioning blocks 20 and the high-precision manufacturing process, the tool is always in a precise position during positioning, avoiding regrinding deviations caused by inaccurate positioning, thus significantly improving regrinding efficiency. At the same time, this symmetrical positioning method can adapt to tools of different sizes and shapes. Simply adjusting the position of the sliding plate 5 allows for quick tool positioning, greatly shortening tool clamping and positioning time and improving overall regrinding efficiency.

[0027] Furthermore, a placement box 6 is fixedly connected to the top of the sliding plate 5. An adjustment groove 13 is provided on the side wall of the placement box 6, and the adjustment groove 13 is connected to the material discharge groove 12. This is mainly to facilitate the adjustment of the cutting tools placed in the placement box 6.

[0028] Furthermore, two symmetrically arranged fixing blocks 7 are fixedly connected to the side wall of the placement box 6. An L-shaped plate 8 is rotatably connected to the two fixing blocks 7. A threaded rod 10 is slidably connected to the side wall of the L-shaped plate 8 opposite to the placement box 6. An extrusion block 11 is threadedly connected to the threaded rod 10. A first strip-shaped opening 9 is opened on the side wall of the placement box 6. A material discharge trough 12 is opened on the placement box 6. A second strip-shaped opening 14 is opened on the side wall of the placement box 6 opposite to the first strip-shaped opening 9. The first strip-shaped opening 9 and the second strip-shaped opening 14 are connected to the material discharge trough 12. A strip-shaped plate 15 is fixedly connected to the sliding plate 5. A material exchange plate 16 is slidably connected to the sliding plate 5 through a sliding device.

[0029] Furthermore, the sliding device includes two symmetrically arranged T-shaped grooves on the sliding plate 5, with T-shaped blocks slidably connected in the two T-shaped grooves. The tops of the two T-shaped blocks are fixed to the side wall of the material changing plate 16 for more stable sliding of the material changing plate 16. A push rod 17 is slidably connected through the strip plate 15, and the other end of the push rod 17 is fixed to the side wall of the material changing plate 16. A spring 19 is sleeved on the side wall of the push rod 17. One end of the spring 19 is fixed to the side wall of the strip plate 15, and the other end of the spring 19 is fixed to the side wall of the push handle 18. This is mainly used to quickly reset the push rod 17 after pushing, making it convenient for the next use. The other end of the push rod 17 is fixedly connected to the push handle 18.

[0030] Working principle:

[0031] In this utility model, firstly, after the tools that need to be sharpened are arranged, they are placed in the placement box 6. Then, the push rod 17 is pushed. As the push rod 17 is pushed, the material changing plate 16 is moved towards the second slot 14 and the tools placed in the placement box 6 are pushed out from the first slot 9.

[0032] As the cutting tool slides and comes into contact with the side wall of the positioning block 20, the push rod 17 can no longer push. At this point, the alignment push stops, and the push rod 17 is returned to its original position under the action of the spring 19. Then, the pressing block 11 is rotated, and the pressing block 11 slides on the threaded rod 10 to push the L-shaped plate 8 to start rotating. During the rotation, the side wall of the L-shaped plate 8 begins to abut against the top side wall of the cutting tool that was just pushed out. The pressing block 11 is rotated again, and the pressing force fixes the cutting tool that was just pushed out. The whole operation process not only saves the time of repeatedly picking up and taking out the cutting tool, but also quickly fixes and grinds the cutting tool, improving the efficiency of the actual sharpening process.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
