Description

Technical Field

[0001] This utility model relates to the field of alloy end mills, specifically an alloy end mill. Background Technology

[0002] This alloy end mill is a powerful tool in the machining field. The cutter body is primarily made of cemented carbide, possessing high hardness, excellent wear resistance, and good hot hardness, enabling it to withstand high-speed cutting. It comes in a variety of head shapes, such as cylindrical, end mills, face mills, and ball end mills, to meet different machining needs for planes, grooves, and curved surfaces. The shank is available in straight and tapered shank versions to ensure a stable connection with the milling machine. The cutting edge is finely ground, with a rationally designed rake angle and clearance angle, resulting in a sharp and efficient cut that significantly reduces cutting forces and tool wear. It is widely used in industries such as machinery manufacturing, mold making, and aerospace, providing reliable assurance for the machining of various parts.

[0003] A search revealed that Chinese patent CN211331508U discloses an alloy end mill. The patent describes a technical solution that reduces the performance of the device by adjusting the length and processing method of the tool used in the device to meet actual processing needs.

[0004] In this solution, although the length of the cutting tool can be quickly adjusted, the tool can only be changed by unscrewing the screws when processing different workpieces. The replacement method is cumbersome, time-consuming and labor-intensive, resulting in a significant reduction in work efficiency. In order to solve this technical problem, this utility model proposes an alloy end mill. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] Example 1: An alloy end mill includes a shank 1, a second shank 13 inside the first shank 1, and fixed blocks 12 fixedly connected to the outer walls of both sides of the second shank 13. A connecting block 5 is fixedly connected to the other side of each fixed block 12. Sliding grooves 4 are formed on both sides of the first shank 1, and the fixed blocks 12 are slidably connected within them. Inner grooves 3 are formed on both sides of the first shank 1, and the connecting blocks 5 are slidably connected within them. A cutting tip 2 is fixedly connected to the other end of the first shank 1, and a cutting tip 17 is fixedly connected to the other end of the second shank 13. A sliding cavity 16 is formed inside the first shank 1, and the second shank 13 is slidably connected within the sliding cavity 16. Adjusting screws 6 are threadedly connected to the inner sides of both sides of the connecting blocks 5, and each adjusting screw 6 has a rotating end. The connecting sleeve 7 is connected to the moving connection. The outer wall of the connecting sleeve 7 is fixedly connected to the ejector block 8. The inner sides of the connecting block 5 are slidably connected to the positioning blocks 9. The inner sides of the tool handle 1 have two pairs of positioning grooves 10, and the positioning grooves 10 correspond to the positioning blocks 9. At the same time, the positioning blocks 9 are slidably connected in the positioning grooves 10. The two ends of one side of the ejector block 8 are inclined. The one side of the positioning block 9 is inclined. The positioning blocks 9 correspond to the ejector block 8. The inner cavity 11 is opened inside the connecting block 5. The ejector block 8 is slidably connected in the inner cavity 11. The outer walls of the two sides of the tool handle 13 are fixedly connected to the limiting blocks 14. The inner side of the tool handle 1 has a pair of limiting grooves 15, and the limiting grooves 15 correspond to the limiting blocks 14. At the same time, the limiting blocks 14 are slidably connected in the limiting grooves 15.

[0025] First, install one end of the tool holder 1 onto the machine. Use the tool tip 2 to process the workpiece. When different workpieces require different sized tool holders, push the connecting block 5 downwards. As the connecting block 5 moves, the tool holder 13 in the slide cavity 16 moves outwards via the fixing block 12. The fixing block 12 is limited in the slide groove 4, and the connecting block 5 is limited in the inner groove 3. When the connecting block 5 moves to the end of the inner groove 3, the tool tip 17 on the tool holder 13 will be fully exposed. At this time, rotate the adjusting screw 6 to move it inwards, which in turn moves the ejector block 8 on the connecting sleeve 7 inwards as well. The ejector block 8 is limited in the inner cavity 11. As the ejector block 8 moves, the positioning block 9 is pushed outwards by the inclined surface, causing it to insert into the positioning groove 10 and be fixed, thus positioning the tool holder 13. When the tool holder 13 moves, the limiting block 14 is limited in the limiting groove 15 to prevent it from rotating within the slide cavity 16. These components work together to allow for quick cutter replacement without disassembly, improving work efficiency.

[0026] Working principle: When using this device, one end of the tool holder 1 is installed on the machine, and the workpiece is processed by the tool tip 2. Different sizes of tool holders 1 are required to process different workpieces. At this time, the connecting block 5 is pushed down. When the connecting block 5 moves, it drives the tool holder 13 in the slide cavity 16 to move outward through the fixing block 12. The fixing block 12 is limited by the slide groove 4, and the connecting block 5 is limited by the inner groove 3. When the connecting block 5 moves to the end of the inner groove 3, the tool tip 17 on the tool holder 13 will be fully exposed. At this time, the adjusting screw 6 is rotated. The rod 6 moves inward as it rotates, which in turn moves the ejector block 8 on the connecting sleeve 7 inward. At the same time, the ejector block 8 is limited within the inner cavity 11. During the movement of the ejector block 8, the positioning block 9 is pushed outward by the inclined surface, and the positioning block 9 is inserted into the positioning groove 10 for fixation, thereby positioning the tool holder 13. During the movement, the tool holder 13 is limited within the limiting groove 15 by the limiting block 14, ensuring that the tool holder 13 will not rotate within the sliding cavity 16. Through their cooperation, the problem of disassembly and replacement is avoided, and the milling cutter can be quickly replaced, improving work efficiency.
