Technical Field

[0001] This invention relates to the field of milling reamer technology, and more particularly to a multifunctional milling reamer with a quick-release mechanism. Background Technology

[0002] In the existing machining field, multi-functional milling reamers have been widely used to achieve composite machining of workpieces, reduce tool change time, and improve process concentration.

[0017] 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. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Reference Figure 1-7 A multi-functional milling reamer with a quick-release mechanism includes a connecting rod body 1, a cutter head 5 is inserted and installed at the bottom of the connecting rod body 1, the top of the cutter head 5 extends into the interior of the connecting rod body 1 through a plug rod 54 and docks with a snap-fit ​​rotating seat 10, the snap-fit ​​rotating seat 10 is connected to a rotating shaft 11 rotatably arranged inside the plug rod 54, and a plurality of ring buckles 7 are engaged with the bottom of the rotating shaft 11 through meshing teeth 12, the ring buckles 7 extend outward and snap with a plurality of cutter bodies 51 arranged on the outer side of the cutter head 5; The outer wall of the cutter head 5 has multiple mounting slots 52. The mounting slots 52 are connected to the inside of the cutter head 5 and the cutter body 51 is installed inside by inserting a block 56. The middle of the insert block 56 has a second slot 57 to connect with the connecting block 13.

[0019] An adjusting block 1 is rotatably mounted in the middle of the connecting rod 1, and an adjusting block 2 is rotatably mounted below the adjusting block 1. Both ends of the adjusting blocks 1 and 2 are set as flat surfaces to mate with the wrench opening. Spring return pins 4 are slidably mounted on the side walls of the adjusting blocks 1 and 2.

[0020] The spring return pin 4 includes a spring and a return pin. The spring is installed inside the adjusting block 1 2 and the adjusting block 2 3, and the return pin is sleeved and connected inside the spring. In its natural state, the return pin extends out of the outer wall of the adjusting block 1 2 and the adjusting block 2 3 under the preload of the spring.

[0021] Multiple limiting grooves 6 are provided on the outer wall of the connecting rod body 1. The locking rotating seat 10 and the ring buckle 7 are respectively limited and slidably installed in the limiting grooves 6. The locking rotating seat 10 is rotatably installed on the upper side inside the connecting rod body 1, and the outer wall of the locking rotating seat 10 is provided with a through hole to connect with the spring reset pin 4. The locking rotating seat 10 is located at the inner center position of the adjusting block 2.

[0022] The ring buckle 7 is rotatably installed inside the connecting rod body 1 and is located below the snap-fit ​​rotating seat 10. The outer walls of both ends of the ring buckle 7 are provided with through holes to connect with the spring reset pin 4. A protrusion is provided on the inner side of the ring buckle 7 to connect with the slot 55 opened on the outer wall of the insertion rod 54.

[0023] The top end of the rotating shaft 11 is fixedly connected to the bottom end of the snap-fit ​​rotating seat 10. The bottom of the rotating shaft 11 is provided with a docking rod 9, which is rectangular and used to snap-fit ​​the inside of the cutter head 5.

[0024] Multiple snap-fit ​​blocks 13 are rotatably mounted on the upper part of the connecting rod 9 via a pin. In its natural state, the snap-fit ​​blocks 13 are embedded in the inner wall of the rotating shaft 11, and the side of the snap-fit ​​blocks 13 facing the rotating shaft 11 is provided with a tooth groove that meshes with the meshing teeth 12. When the rotating shaft 11 rotates, the multiple snap-fit ​​blocks 13 are rotated around the shaft through the meshing of the meshing teeth 12.

[0025] The inner side of the ring buckle 7 has a protrusion with a sloping top surface. When the ring buckle 7 rotates, the protrusion presses against the slot 55 on the outer wall of the insertion rod 54 and is guided by the sloping surface to lift the insertion rod 54.

[0026] The upper part of the blade body 51 is equipped with a tapered connector 53, and the top of the tapered connector 53 is provided with a plug rod 54. The middle part of the plug rod 54 is provided with a through hole to connect with the rotating shaft 11. The entire blade body 51 is used to insert and install into the plug hole 8 opened at the bottom of the connecting rod body 1 to complete the matching insertion.

[0027] In this embodiment, the wrench is connected to the adjusting block 2 and simultaneously presses the two spring return pins 4 on the outer wall of the extruder, causing the spring return pins 4 to press inward until they are connected to the through hole on the outer wall of the snap-fit ​​rotating seat 10. At this time, the adjusting block 2 is driven to connect with the snap-fit ​​rotating seat 10. The wrench is rotated to drive the adjusting block 2 and the snap-fit ​​rotating seat 10 to rotate. At this time, the rotating shaft 11 connected to the snap-fit ​​rotating seat 10 rotates synchronously. The rotating shaft 11 rotates inside the cutter body 51 and drives the multiple snap-fit ​​blocks 13 connected to the bottom of the cutter head 5 to rotate through the meshing teeth 12 at the bottom. The snap-fit ​​blocks 13 rotate and retract into the cutter head 5 and disengage from the snap-fit ​​groove 2 57 provided inside the cutter body 51. At this point, the blade body 51 is unfastened and can be pulled out of the mounting slot 52 under external force, completing the individual replacement of the blade body 51. Correspondingly, during the installation process of the blade body 51, the locking block 13 is rotated outward by the fastening shaft 11, thereby completing the locking and fastening with the second locking slot 57. The blade body 51 is double-fastened with the mounting slot 52 and the first locking slot 55 to ensure stability during operation.

[0028] At this time, the adjusting block 2 3 can be rotated to drive the locking rotating seat 10 to rotate, so that the protrusion on the inclined surface inside the locking rotating seat 10 disengages from the slot 1 55 at the top of the cutter head 5. At this time, the cutter head 5 can be pulled down to complete the overall disassembly operation of the cutter head 5.

[0029] Compared to traditional milling reamers that are locked by fasteners such as screws, this mechanism allows for independent disassembly of the cutter head 5 and the cutter body 51 through the setting of adjustment block 1 2 and adjustment block 2 3. The rotational fastening method effectively improves the efficiency of installation and disassembly, and the quick-release mechanism ensures the efficiency of replacing the cutter head 5.

[0030] In addition, it should be noted that the connecting rod 1 is used to connect the machine spindle, and the specific connection method will not be explained further.

[0031] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
