Description

Technical Field

[0001] This utility model relates to the field of milling cutter regrinding technology, and in particular to an auxiliary device for milling cutter regrinding. Background Technology

[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling operations. After long-term use, milling cutters will wear down, which can easily cause the cutting edge to become dull. Therefore, they need to be re-sharpened. During the re-sharpening process, an auxiliary device is needed for positioning. However, the existing auxiliary devices are too simple in structure and the operation steps are cumbersome.

[0003] The technical solution disclosed in Chinese Patent No. CN214135197U describes a milling cutter side cutting edge guiding mechanism that can be adjusted from multiple angles, facilitating operation and effectively solving the problem of difficult re-sharpening of small-diameter end mills. Furthermore, the device allows for easy replacement of clamping components for both tapered shank and straight shank end mills, enabling the selection of appropriate clamping components for different types of end mills and effectively reducing adjustment time during machine tool processing.

[0004] However, the device still has shortcomings: it has poor stability in holding the shank of tapered end mills, the tapered shank is easy to detach from the inner sleeve of the end mill clamping sleeve, and the movement and position adjustment of the end mills require manual operation, which is time-consuming and labor-intensive.

[0026] Example 1, as Figures 1-4As shown, this utility model proposes a milling cutter sharpening auxiliary device, including a guide rail 1, a rotating cylinder 8, a slider B9, a locking ring 14, a fixed base 15, and a driving mechanism. A slide table 4 is slidably connected to the guide rail 1, and a mounting bracket 6 is mounted on the slide table 4. An adjustment mechanism for adjusting the position of the mounting bracket 6 is also provided on the guide rail 1. The adjustment mechanism includes a linear module A5 and a linear module B7. The body of the linear module A5 is connected to the guide rail 1, and its output end is connected to the slide table 4. The body of the linear module B7 is connected to the slide table 4 and perpendicular to the linear module A5, and its output end is connected to the mounting bracket 6. The rotating cylinder 8 is rotatably mounted on the mounting bracket 6. A motor 61 for driving the rotating cylinder 8 is mounted on the mounting bracket 6. A socket 81 is coaxially provided on the rotating cylinder 8, and several grooves B82 communicating with the socket 81 are arranged in a circular array around the center of the socket 81. Several through holes 83 corresponding to and communicating with each groove B82 are provided on the rotating cylinder 8. Each slider B9 is slidably disposed within a corresponding groove B82. A wedge block 10 is connected to the opposite end of each slider B9, and each wedge block 10 is inserted into a corresponding through hole 83. A clamping plate 11 is rotatably connected to the adjacent end of each slider B9. A centrally located adapter seat is mounted on each slider B9. Each clamping plate 11 is connected to the movable end of the adapter seat on its corresponding side. A magnet 12 is mounted on the side of each clamping plate 11 away from the opening of the insertion hole 81. An iron plate 13 is mounted on each clamping plate 11 and magnetically engages with the magnet 12. Flexible anti-slip pads are provided on the adjacent sides of each clamping plate 11. A locking ring 14 is fitted onto the rotating cylinder 8 and screwed to it. One side of the locking ring 14 abuts against the inclined surface of the wedge block 10. The fixed base 15 is connected to the guide rail 1. A movable plate 17 is slidably mounted on the fixed base 15. Several guide rods B16 are mounted on the fixed base 15, passing through the movable plate 17 and slidably connected to it. A rotary table 18 is mounted on the movable plate 17, and a grinding wheel 19 is mounted on the rotary table 18. The drive mechanism includes a screw 20, an internally threaded tube 21, and a worm gear 23. The top end of the screw 20 is connected to the bottom of the movable plate 17. The body of the internally threaded tube 21 is rotatably connected to the fixed base 15. The screw 20 is inserted into the internally threaded tube 21 and helically connected to it. A worm wheel 22 is coaxially mounted on the internally threaded tube 21. The body of the worm gear 23 is rotatably connected to the fixed base 15. The worm gear 23 meshes with the worm wheel 22, and a crank 2 is mounted at one end of the worm gear 23.

[0027] In this embodiment, the end mill shank is first inserted into the insertion hole 81. Then, the locking ring 14 is rotated. The edge of the locking ring 14 abuts against the inclined surface of the wedge block 10, causing the wedge block 10 to drive the slider B9 to slide until the clamping plate 11 is pressed against the outer wall of the end mill shank. During this process, if the end mill shank is straight, the clamping plate 11 remains parallel to the slider B9. If the end mill shank is tapered, the clamping plate 11 automatically flips and tilts so that its adjacent sides are both in contact with the outer surface of the end mill shank. The anti-disengagement ring on the tapered end mill shank is used to position and prevent disengagement. After the end mill shank is removed, the clamping plate 11 automatically returns to parallel with the slider B9 under the attraction of the magnet 12. After the milling cutter is fixed, the linear modules A5 and B7 are activated to adjust the position of the milling cutter. The crank 24 is driven to rotate, which in turn drives the worm gear 23 to rotate, which in turn drives the worm wheel 22 and the internal thread tube 21 to rotate. This causes the movable plate 17 to rise under the push of the screw 20, so that the end machining point of the milling cutter contacts the edge of the grinding wheel 19. Then, the grinding wheel 19 is activated to grind and repair the end cutting edge of the milling cutter. After the end cutting edge is ground and repaired, the edge of its spiral groove is ground. At this time, the rotary table 18 is activated to adjust the wheel angle of the grinding wheel 19 to be perpendicular to the mounting bracket 6. The position of the milling cutter is adjusted so that the wheel of the grinding wheel 19 is engaged in the spiral groove of the milling cutter. At this time, the feed speed of the linear module A5 and the rotation speed of the motor 61 are adjusted. The two work together to make the edge of the milling cutter rotate and move forward. After moving forward to the position, it retracts and resets, thus achieving the grinding of both sides of the spiral groove edge of the milling cutter.

[0028] Example 2, as Figure 1 and Figure 2 As shown, the milling cutter grinding auxiliary device proposed in this utility model, compared with the first embodiment, has a T-shaped block 101 at the bottom of the guide rail 1, and a slide groove A102 on the guide rail 1. A slider A2 is slidably disposed in the slide groove A102. A pin 201 penetrating the T-shaped block 101 is disposed at the bottom of the slider A2. A finger groove 202 is disposed on the slider A2. A tensioning component 3 for pressing the slider A2 is disposed in the slide groove A102. The tensioning component 3 includes a guide rod A31 and a spring 32. The guide rod A31 penetrates the slider A2 and is slidably connected to it. The two ends of the guide rod A31 are respectively connected to the upper wall and the lower wall of the slide groove A102. The two ends of the spring 32 abut against the upper wall of the slide groove A102 and the upper surface of the slider A2, respectively.

[0029] In this embodiment, when fixing the guide rail 1, the upper slider A2 causes the pin 102 to rise. Maintaining this state, the T-shaped block 101 is inserted laterally along the slot of the machine tool until the guide rail 1 is in place. At this time, the pin 102 automatically engages in the positioning hole under the action of spring tension. When it is necessary to remove the guide rail 1, simply pull the upper slider A2 to disengage the pin 102 from the positioning hole, and the guide rail 1 can be pulled laterally to remove it from the machine tool.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
