[0002] Milling machines are machine tools that use milling cutters to machine various surfaces of workpieces. Milling is a widely used machining method in mechanical processing, mainly used for cutting, carving, or shaping metals or other materials. The basic principle of milling is to cut the workpiece with a rotating milling cutter to obtain the required shape and size. The milling cutter is the tool used to cut the workpiece in milling, usually made of carbide or high-speed steel. Common types of milling cutters include face cutters, end mills, ball end mills, and slot cutters. Each type of milling cutter has a specific shape and cutting edge design to adapt to different machining needs. Milling is a highly efficient machining method, widely used in precision machining tasks in many industries. Through continuous development and improvement, the status and role of milling technology in manufacturing is becoming increasingly important.

[0003] For some high-precision and complex workpieces, multiple milling cutters are required to process them during milling. Conventional milling cutter structures make it difficult to replace the cutters on the spindle. When the workpiece's processing requirements change, operators need to disassemble and replace the cutters, wasting considerable time and significantly reducing processing efficiency. Furthermore, conventional milling cutter structures struggle to effectively process inclined surfaces. Adjusting the workpiece angle requires repositioning the cutters, adding additional steps. To address these issues, a convertible milling cutter structure for milling machines is proposed. Utility Model Content

This solves the issues of current milling methods, which require multiple milling cutters to work together on high-precision and complex workpieces. Conventional milling cutter structures make it difficult to replace the cutters on the spindle. When the workpiece's processing requirements change, operators need to disassemble and replace the cutters, wasting considerable time and significantly reducing processing efficiency. Furthermore, when machining inclined surfaces, conventional milling cutter structures struggle to effectively process the workpiece. Adjusting the workpiece angle requires repositioning the cutter, adding numerous processing steps.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a convertible milling cutter structure for milling machine processing, comprising a milling machine body, a mounting support fixedly connected to the upper rear end of the milling machine body, an angle adjustment motor fixedly mounted on the upper rear end of the mounting support, the output end of the angle adjustment motor passing through the rear side of the mounting support and fixedly connected to a mounting plate, a rotary motor fixedly mounted on the upper front end of the mounting plate, the output end of the rotary motor passing through the upper side of the mounting plate and fixedly connected to a spindle, a fixed plate rotatably connected to the spindle, and the lower part of the fixed plate...

Detailed Implementation

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] Reference Figure 1-3As shown, a convertible milling cutter structure for milling machine processing includes a milling machine body 1. Several operation buttons 2 are provided on the upper front side of the milling machine body 1. A mounting support 3 is fixedly connected to the upper rear end of the milling machine body 1. An angle adjustment motor 4 is fixedly installed on the upper rear side of the mounting support 3, which can effectively adjust the processing angle of the milling cutter 17. The output end of the angle adjustment motor 4 passes through the rear side of the mounting support 3 and is fixedly connected to a mounting plate 5. A rotary motor 6 is fixedly installed on the upper front side of the mounting plate 5. The output end of the rotary motor 6 passes through the upper side of the mounting plate 5 and is fixedly connected to a spindle 7. A fixed plate 8 is rotatably connected to the spindle 7. Fixed rods 9 are fixedly connected to the left and right ends of the upper side of the fixed plate 8. The upper sides of the two fixed rods 9 are fixedly connected to the lower side of the mounting plate 5.

[0020] Mounting frames 10 are snapped onto the four sides of the lower side of the fixing plate 8. A guide frustum 11 is fixedly connected to the center of the lower side of the fixing plate 8. The lower side of the spindle 7 is flush with the lower side of the guide frustum 11, effectively guiding the locking block 20 into the slot 12. The surface of the spindle 7 is rotatably connected to the interior of the guide frustum 11. A slot 12 is provided at the center of the lower side of the spindle 7. A first push rod 13 is fixedly installed at the upper end of the slot 12. A push plate 14 is fixedly connected to the output end of the first push rod 13. The side of the push plate 14 is slidably connected to the inner wall of the slot 12, effectively pushing the locking block 20 out of the slot 12, facilitating the replacement of the milling cutter 17. A second push rod 15 is fixedly installed at the lower outer side of the mounting frame 10. The output end of the second push rod 15 passes through the outside of the mounting frame 10 and is fixedly connected to a rotating joint 16. A milling cutter 17 is slidably connected inside the rotating joint 16, which can effectively install and remove the milling cutter 17. A connecting ring 18 is rotatably connected to the upper end of the milling cutter 17. A spring 19 is sleeved on the surface of the milling cutter 17. The lower end of the spring 19 is fixedly connected to the upper side of the rotating joint 16, and the upper end of the spring 19 is fixedly connected to the lower side of the connecting ring 18, ensuring that the milling cutter 17 can be engaged with the spindle 7. A locking block 20 is fixedly connected to the upper side of the milling cutter 17 through the inside of the connecting ring 18. The upper edge of the locking block 20 is arc-shaped and can slide along the edge of the guide frustum 11. The upper side of the connecting ring 18 is rotatably connected to the lower side of the locking block 20.

[0021] Working principle: The workpiece is fixed on the milling machine body 1. The milling cutter 17 is installed inside each rotating joint 16 as needed. The mounting frame 10 is engaged with the fixing plate 8. Under the elastic force of the spring 19, the locking block 20 abuts against the lower side of the fixing plate 8. When the milling cutter 17 needs to be installed, the second push rod 15 is controlled to move the corresponding rotating joint 16 and the milling cutter 17 inward. The upper arc-shaped edge of the locking block 20 slides inward along the edge of the guide frustum 11. The spring 19 is continuously compressed during the movement. When it moves below the slot 12, the locking block 20, under the elastic force of the spring 19, engages upward with the spindle 7, completing the installation of the milling cutter 17. The milling cutter 17 needs to be removed. At 7 o'clock, the first push rod 13 is controlled to move the push plate 14 downward, pushing the locking block 20 out of the locking slot 12. Then, the corresponding second push rod 15 is controlled to move the milling cutter 17 and the locking block 20 outward. When the upper side of the locking block 20 abuts against the lower side of the fixing plate 8, the milling cutter 17 is disassembled. When machining the inclined surface of the workpiece, the inclined surface can be placed and fixed in the front-back direction before machining. By rotating the angle adjustment motor 4, the mounting plate 5 is rotated to be parallel to the inclined surface. At this time, the milling cutter 17 is perpendicular to the inclined surface, and the inclined surface can be machined. At this time, the position of the workpiece remains unchanged, and the rotation angle of the milling cutter 17 can be monitored by the sensor. No secondary positioning is required, which effectively reduces the machining process.
