Description

Technical Field

[0001] This invention relates to the field of milling technology, specifically to a honeycomb milling machine tool with spindle orientation function. Background Technology

[0002] Plunge milling is a machining process that removes material by feeding a milling cutter axially (perpendicularly into the workpiece). It is often used for efficient machining of complex structures such as deep cavities, narrow slits, and high-hardness materials. Its principle is similar to a combination of drilling and milling. The cutter moves linearly along the axis to cut into the workpiece, while simultaneously rotating. It is suitable for scenarios that are difficult to complete using traditional side milling.

[0003] Traditional milling machine tools typically use tool holders that are clamped and fixed to the spindle for easy tool holder replacement. However, this traditional clamping method relies solely on two opposing clamping blocks, resulting in insufficient clamping force. When the spindle rotates and contacts the workpiece, the connection between the tool holder and the spindle easily loosens, leading to tool holder misalignment and affecting normal plunge milling operations. Therefore, it is necessary to provide a honeycomb plunge milling machine tool with spindle orientation functionality to address these issues. Summary of the Invention

[0004] Therefore, it is necessary to provide a honeycomb milling machine tool with spindle orientation function to address the existing technical problems.

[0005] To solve the problems of the prior art, the technical solution adopted by the present invention is as follows: a honeycomb milling machine tool with spindle orientation function, including a tool holder and a rotary roller shaft. A groove is formed along the axial direction of the rotary roller shaft, and a pull rod is provided within the groove. One end of the rotary roller shaft is connected to a mounting sleeve. A pull claw is provided at the end of the mounting sleeve facing the rotary roller shaft, and one end of the pull claw is an elastically flared end.

[0008] Furthermore, each arc-shaped protrusion has a ring of inwardly tapering second conical surface formed on its outer wall, and the end of the snap-fit ​​platform facing the columnar groove has a ring of third conical surface that fits into the second conical surface.

[0009] Furthermore, a connecting ring is fixedly fitted on the outer wall of the end sleeve. Each set of telescopic locking components also includes a guide slide, a transmission rod, and a drive rod. The guide slide is fixedly connected to the connecting ring. The guide slide includes a long frame and a short frame. The long frame is parallel to the pull rod, and the short frame is perpendicular to the long frame. The telescopic rod is slidably connected to the short frame. The short frame is provided with a first elastic element connected to the telescopic rod. The drive rod is parallel to the telescopic rod and is slidably connected to the connecting sleeve. One end of the drive rod passes into the connecting sleeve. Two symmetrical push bars are formed on the outer wall of the pull rod. One end of the push bar is formed with a first inclined surface. The end of the drive rod that passes into the connecting sleeve is formed with a second inclined surface that wedges with the first inclined surface. The connecting sleeve is provided with a second elastic element connected to the drive rod. The transmission rod is slidably connected to the long frame. The drive rod is connected to the telescopic rod through the transmission rod.

[0010] Furthermore, the first elastic element includes a first slider, a first spring, and a first stop. A first strip-shaped clearance groove is provided on the short frame.

[0032] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0033] refer to Figures 1 to 14 The shown is a honeycomb milling machine tool with spindle orientation function, including a tool holder 1 and a rotary roller shaft 2. A groove 3 is formed along the axial direction of the rotary roller shaft 2, and a drawbar 4 is disposed within the groove 3. One end of the rotary roller shaft 2 is connected to a mounting sleeve 5, and a drawbar 6 is provided at the end of the mounting sleeve 5 facing the rotary roller shaft 2. One end of the drawbar 6 is an elastically flared end (e.g., ...). Figure 8 As shown), one end of the drawbar 4 is provided with a push-pull pin 7 that passes through the drawbar claw 6 (in conjunction with...). Figure 8 and Figure 13 The mounting sleeve 5 has a conical groove 8 at one end, with the smaller diameter end of the conical groove 8 facing the pull claw 6. One end of the handle 1 has a conical head 9 that fits into the conical groove 8. The conical head 9 has a columnar groove 10 for the push-pull pin 7 and the pull claw 6 to insert into. The inner wall of the columnar groove 10 has an annular locking platform 11. One end of the push-pull pin 7 has an expanded head 12 that drives the pull claw 6 to expand outward and abut against the locking platform 11. A directional locking mechanism is provided between the mounting sleeve 5 and the handle 1. The directional locking mechanism includes two sets of telescopic locking parts in a symmetrical state. Each set of telescopic locking parts includes a semi-circular retaining ring 13 and a telescopic rod 14. The telescopic rod 14 is connected to the mounting sleeve 5, and the semi-circular retaining ring 13 is connected to the telescopic rod 14. The semi-circular retaining ring 13 corresponds to the handle 1.

[0034] This device is used to position the tool holder 1 during installation, preventing it from becoming loose, and facilitating quick assembly and disassembly. The specific installation process is as follows: Initially, the pull rod 4 is extended. At this time, the enlarged head 12 on the push-pull pin 7 extends from the pull claw 6. The elastic flared end of the pull claw 6 will then elastically converge inward. When the conical head 9 of the tool holder 1 is inserted into the conical groove 8, the push-pull pin 7 and the pull claw 6 will be inserted into the cylindrical groove 10 within the conical head 9. Afterward, the pull rod 4 retracts, and the push-pull pin 7 on the pull rod 4 will cause the enlarged head 12 to press against the elastic flared end of the pull claw 6. During this process, the enlarged head 12... When the pull claw 6 is in contact with the concave groove 8, the elastic flared end of the pull claw 6 will expand outward and abut against the locking platform 11 on the inner wall of the columnar groove 10. In this way, the tool handle 1 will be fixed in the conical groove 8 by the pull claw 6. During the process of the pull rod 4 retracting backward, the telescopic rod 14 in each set of telescopic locking parts will drive the semi-circular retaining ring 13 to press against the tool handle 1. Finally, the tool handle 1 will be fixed by the pull claw 6 and pressed by the two opposing semi-circular retaining rings 13. In this way, the tool handle 1 is positioned by the cooperation of the conical head 9 and the conical groove 8. The bidirectional fastening of the pull claw 6 and the semi-circular retaining ring 13 ensures that the tool handle 1 will not loosen. Furthermore, the tool handle 1 can be quickly replaced by extending the pull rod 4.

[0035] To demonstrate the specific structure of the 6-piece baffle, the following features were set:

[0036] Mounting sleeve 5 includes a connecting sleeve 15 and an end sleeve 16 coaxially connected end to end. The end sleeve 16 is coaxially connected to the rotating roller shaft 2 through the connecting sleeve 15. The connecting sleeve 15 is coaxially provided with a threaded groove 52 and a through groove 17 (e.g., threaded groove 52 and through groove 17) coaxially connected end to end. Figure 7 As shown), the through groove 17 is connected to the sliding groove 3. The puller claw 6 includes a threaded screw sleeve 18 and several elastic plates 19. The threaded screw sleeve 18 is fixed in the threaded groove 52. The several elastic plates 19 are evenly distributed on the threaded screw sleeve 18 along the circumferential direction, and there is a gap between adjacent elastic plates 19. The several elastic plates 19 are the elastic flared ends of the puller claw 6. The conical groove 8 (as shown) Figure 14 As shown, the end sleeve 16 is opened at the end opposite to the connecting sleeve 15, and the end sleeve 16 facing the connecting sleeve 15 has a receiving groove 20 that communicates with the threaded groove 52.

[0037] When installing the puller claw 6, first screw the threaded coupling sleeve 18 on the puller claw 6 into the threaded groove 52, and then fix the connecting sleeve 15 to the end of the rotating roller shaft 2. During this process, the push-pull pin 7 on the puller rod 4 will pass through the threaded coupling sleeve 18 and several elastic plates 19 in sequence. Then, fix the enlarged head 12 to the protruding end of the push-pull pin 7. After the enlarged head 12 is fixed, fix the end sleeve 16 to the connecting sleeve 15. During this process, the enlarged head 12, the push-pull pin 7, and several elastic plates 19 pass through the receiving groove 20 and then into the conical groove. Inside 8, when processing the enlarged head 12, a threaded sleeve is formed at one end of the enlarged head 12. When processing the push-pull pin 7, a threaded surface that mates with the threaded sleeve is formed on the outer wall of the push-pull pin 7. The enlarged head 12 is fixedly connected to the push-pull pin 7 through the threaded sleeve. In the initial state, several elastic pieces 19 will gather inward due to elasticity and adhere to the outer wall of the threaded sleeve. When the pull rod 4 retracts, the push-pull pin 7 will drive the enlarged head 12 to press against several elastic pieces 19. After that, several elastic pieces 19 will expand outward synchronously and abut against the snap-fit ​​platform 11 in the conical groove 8.

[0038] To demonstrate how the enlarged head 12 drives the broaching jaws 6 to expand outward, the following features are provided:

[0039] The end of the enlarged head 12 facing the push-pull pin 7 is formed with a first conical surface 21 that gradually narrows inward. Each elastic piece 19 has an arc-shaped protrusion 22 formed on the end facing the enlarged head 12. The inner wall of the arc-shaped protrusion 22 has a conical concave surface 23 that fits into the first conical surface 21.

[0040] When the pull rod 4 retracts, the push-pull pin 7 will cause the enlarged head 12 to press against the pull claw 6. During this process, the first conical surface 21 on the enlarged head 12 will engage with the conical concave surface 23 on each arc-shaped protrusion 22. As the pull rod 4 continues to retract, each elastic piece 19 will be driven to expand outward through the wedge engagement between the conical concave surface 23 and the first conical surface 21. Finally, the arc-shaped protrusion 22 on each elastic piece 19 will abut against the locking platform 11.

[0041] To demonstrate how the curved protrusion 22 abuts against the locking platform 11, the following features are provided:

[0042] Each arc-shaped protrusion 22 has a ring of inwardly tapering second-order conical surfaces 24 formed on its outer wall. The end of the snap-fit ​​platform 11 facing the columnar groove 10 has a ring of third-order conical surfaces 25 that fit snugly against the second-order conical surfaces 24 (e.g., ...). Figure 4 (As shown).

[0043] As the elastic plate 19 is driven outward by the expanding head 12, the arc-shaped protrusion 22 on the elastic plate 19 will gradually approach the locking platform 11. After that, the second conical surface 24 on the arc-shaped protrusion 22 will fit against the third conical surface 25 on the locking platform 11. Finally, the conical head 9 on the tool holder 1 will be pressed tightly against the conical groove 8 from the inside by the elastic plate 19.

[0044] To demonstrate how the telescopic rod 14 extends and retracts, the following features are provided:

[0045] A connecting ring 26 is fixedly sleeved on the outer wall of the end sleeve 16. Each set of telescopic locking components also includes a guide slide, a transmission rod 27, and a drive rod 28. The guide slide is fixedly connected to the connecting ring 26. The guide slide includes a long strip 29 and a short strip 30. The long strip 29 is parallel to the pull rod 4, and the short strip 30 is perpendicular to the long strip 29. The telescopic rod 14 is slidably connected to the short strip 30. The short strip 30 is provided with a first elastic element connected to the telescopic rod 14. The drive rod 28 is parallel to the telescopic rod 14 and is slidably connected to the connecting sleeve 15. One end of the drive rod 28 passes into the connecting sleeve 15. Two symmetrical push bars 31 are formed on the outer wall of the pull rod 4 (e.g., Figure 6 As shown), one end of the push bar 31 is formed with a first inclined surface 32, and one end of the drive rod 28 that passes into the connecting sleeve 15 is formed with a second inclined surface 33 that wedges with the first inclined surface 32. The connecting sleeve 15 is provided with a second elastic element connected to the drive rod 28. The transmission rod 27 is slidably connected to the long frame 29, and the drive rod 28 is connected to the telescopic rod 14 through the transmission rod 27.

[0046] The telescopic rod 14 slides along the length of the short frame 30 (e.g.) Figure 10 As shown), the transmission rod 27 slides along the length of the long frame 29, and the drive rod 28 slides along the radial direction of the drawbar 4. In the initial state, the drawbar 4 is in the extended state. At this time, several elastic plates 19 on the drawbar claw 6 close inward, and the drive rod 28 is in the retracted state of the connecting sleeve 15 through the second elastic element. The telescopic rod 14 drives the semi-circular retaining ring 13 to be in the retracted state away from the tool holder 1. When the drawbar 4 retracts inward, the enlarged head 12 connected to the push-pull pin 7 will drive several elastic plates 19 to expand outward. At the same time, each push bar 31 will drive the drive rod 28 to extend outward through the cooperation of the first inclined surface 32 and the second inclined surface 33. During this process, the outwardly extended drive rod 28 will drive the telescopic rod 14 to extend toward the tool holder 1 through the transmission rod 27. Thus, the semi-circular retaining ring 13 set on the telescopic rod 14 will gradually approach the tool holder 1, and finally the tool holder 1 will be clamped by the two opposing semi-circular retaining rings 13.

[0047] To demonstrate the specific structure of the first elastic element, the following features were set:

[0048] The first elastic element includes a first slider 34, a first spring 35, and a first stop block 36. A first strip-shaped clearance groove 37 is provided on the short frame 30. The length direction of the first strip-shaped clearance groove 37 is parallel to the sliding direction of the telescopic rod 14. The first stop block 36 is fixedly connected to the short frame 30. One end of the first slider 34 passes through the first strip-shaped clearance groove 37 and is fixedly connected to the telescopic rod 14. The first spring 35 is fixedly disposed between the first slider 34 and the first stop block 36.

[0049] In the initial state, the first spring 35 drives the first slider 34 away from the first stop block 36 through elastic force. At this time, the telescopic rod 14 connected to the first slider 34 will drive the corresponding semi-circular retaining ring 13 to be in a retracted state away from the tool holder 1. When the pull rod 4 retracts, the drive rod 28 extends outward and drives the telescopic rod 14 to extend outward through the transmission rod 27. Finally, the two semi-circular retaining rings 13 will meet each other and clamp the tool holder 1.

[0050] To demonstrate the specific structure of the second elastic element, the following features were set:

[0051] The connecting sleeve 15 has two symmetrical guide grooves 38 (e.g.) Figure 7 As shown), the length direction of each guide groove 38 is perpendicular to the axial direction of the pull rod 4. Two symmetrical guide grooves 39 are formed on the inner wall of the connecting sleeve 15. The length direction of each guide groove 39 is parallel to the axial direction of the pull rod 4, and the guide grooves 38 and 39 are connected. Each drive rod 28 slides within its corresponding guide groove 38, and each pusher 31 slides within its corresponding guide groove 39. The second elastic element includes a second slider 40, a second spring 41, and a second stop 42. The second slider 40 is fixedly connected to the drive rod 28 (e.g., ...). Figure 3 As shown), the second stop block 42 is fixedly connected to the connecting sleeve 15 via the support rod 43, and the second spring 41 is fixedly disposed between the second slider 40 and the second stop block 42.

[0052] When the drawbar 4 is extended, the second spring 41 drives the second slider 40 to move toward the connecting sleeve 15 through its elastic force. During this process, the drive rod 28 is driven by the second slider 40 to retract into the connecting sleeve 15. Finally, the second inclined surface 33 on the drive rod 28 will abut against the first inclined surface 32 on the push bar 31. After that, when the drawbar 4 retracts, the push bar 31 on the drawbar 4 will press against the drive rod 28. Thus, through the cooperation of the first inclined surface 32 and the second inclined surface 33, the drive rod 28 will be driven by the push bar 31 to extend outward. After the drive rod 28 extends, through the action of the transmission rod 27, the telescopic rod 14 will drive the corresponding semi-circular retaining ring 13 to press against the tool holder 1.

[0053] To demonstrate how the transmission rod 27 connects the telescopic rod 14 and the drive rod 28, the following features are provided:

[0054] The two ends of the transmission rod 27 are respectively formed with a third inclined surface 44 and a fourth inclined surface 45 (e.g. Figure 10 As shown), one end of the telescopic rod 14 is formed with a fifth inclined surface 46 that cooperates with the wedge of the third inclined surface 44, and one end of the drive rod 28 is formed with a sixth inclined surface 47 that cooperates with the wedge of the fourth inclined surface 45. The long frame 29 is provided with a third elastic element connected to the transmission rod 27. The third elastic element includes a third slider 48, a third spring 49 and a third stop block 50. The long frame 29 is provided with a second strip-shaped clearance groove 51. The length direction of the second strip-shaped clearance groove 51 is parallel to the sliding direction of the transmission rod 27. The third stop block 50 is fixedly connected to the long frame 29. One end of the third slider 48 passes through the second strip-shaped clearance groove 51 and is fixedly connected to the transmission rod 27. The third spring 49 is fixedly located between the third slider 48 and the third stop block 50.

[0055] When the drawbar 4 retracts, it will drive the drive rod 28 to extend outward through the push bar 31. When the drive rod 28 extends, the transmission rod 27 will be driven to slide towards the telescopic rod 14 through the wedge engagement of the sixth inclined plane 47 and the fourth inclined plane 45. Then, through the wedge engagement of the fifth inclined plane 46 and the third inclined plane 44, the transmission rod 27 will drive the telescopic rod 14 to extend towards the tool holder 1. Finally, the tool holder 1 will be locked by two opposing semi-circular retaining rings 13.

[0056] Working principle:

[0057] This device is used to position the tool holder 1 during installation, preventing it from becoming loose, and facilitating quick assembly and disassembly. The specific installation process is as follows: Initially, the pull rod 4 is extended. At this time, the enlarged head 12 on the push-pull pin 7 extends from the pull claw 6. The elastic flared end of the pull claw 6 will then elastically converge inward. When the conical head 9 of the tool holder 1 is inserted into the conical groove 8, the push-pull pin 7 and the pull claw 6 will be inserted into the cylindrical groove 10 within the conical head 9. Afterward, the pull rod 4 retracts, and the push-pull pin 7 on the pull rod 4 will cause the enlarged head 12 to press against the elastic flared end of the pull claw 6. During this process, the enlarged head 12... When the pull claw 6 is in contact with the concave groove 8, the elastic flared end of the pull claw 6 will expand outward and abut against the locking platform 11 on the inner wall of the columnar groove 10. In this way, the tool handle 1 will be fixed in the conical groove 8 by the pull claw 6. During the process of the pull rod 4 retracting backward, the telescopic rod 14 in each set of telescopic locking parts will drive the semi-circular retaining ring 13 to press against the tool handle 1. Finally, the tool handle 1 will be fixed by the pull claw 6 and pressed by the two opposing semi-circular retaining rings 13. In this way, the tool handle 1 is positioned by the cooperation of the conical head 9 and the conical groove 8. The bidirectional fastening of the pull claw 6 and the semi-circular retaining ring 13 ensures that the tool handle 1 will not loosen. Furthermore, the tool handle 1 can be quickly replaced by extending the pull rod 4.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
