Description

Technical Field

[0001] This invention application relates to the field of combination milling cutter technology, specifically a multi-purpose combination milling cutter. Background Technology

[0002] Milling cutters are rotary cutting tools used for milling operations. They remove excess material from the workpiece through intermittent cutting with their teeth. They are mainly used for machining planes, steps, grooves, and shaped surfaces, as well as for cutting off workpieces. Their structures are divided into three categories: integral, insert-tooth, and indexable. According to their functions, they can be divided into cylindrical milling cutters, face milling cutters, end mills, three-sided milling cutters, etc. To meet the needs of multi-purpose machining, most existing milling cutters adopt a modular design.

[0003] Most existing modular end mills are directly fixed to the corresponding loading plate using fasteners. Current modular end mills have the following problems in use: First, each end mill is fixed to the loading plate with bolts or similar fasteners. After each complex machining operation, when the end mill needs to be replaced according to the process requirements, the operation is time-consuming and laborious, affecting machining efficiency. Second, during the cutting process, because there are many end mills on the loading plate, and the length of each end mill cannot be adjusted during the conversion process, when one end mill is cutting, the others may affect the workpiece, thus limiting the machining range of the modular end mill and greatly reducing its applicability. Summary of the Invention

[0004] To address the problems of time-consuming and laborious operation when changing individual milling cutters in a multi-purpose combination milling cutter and the tendency for milling cutters to interfere with each other during cutting, this invention provides a multi-purpose combination milling cutter to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A multi-purpose combination milling cutter includes a milling cutter head, a milling cutter shank, and a loading disc. Each milling cutter head has a milling cutter shank fixed to its top. The loading disc has several loading slots equidistantly arranged around its circumference. Each loading slot has a rotatable mounting plate inside. Each mounting plate is rotatably connected to a connecting sleeve via a damping bearing. Each connecting sleeve contains a detachable milling cutter shank. A drive assembly is rotatably connected to the milling cutter head for driving the milling cutter shank to rotate.

[0007] Further, a fixed locking block is fixed in the middle of the connecting sleeve. A set of fixed pin bars are symmetrically and slidably arranged inside the fixed locking block. Unloading card slots are formed on the opposite sides of the two fixed pin bars. Springs are fixed between one end of each fixed pin bar close to the center of the loading disc and the inner wall of the fixed locking block. Fixed locking grooves cooperating with the fixed pin bars are formed on the side walls of each milling cutter rod. Locking rods are fixed to one end of each group of two fixed pin bars away from the springs. The locking rods are slidably sleeved inside the fixed locking block.

[0008] Further, the milling cutter rod is inserted inside the connecting sleeve. Positioning grooves are symmetrically formed at one end of the milling cutter rod away from the milling cutter head. Connecting grooves cooperating with the milling cutter rod and the positioning grooves are formed inside the connecting sleeve. One end of each milling cutter rod away from the milling cutter head penetrates to the outside of the connecting sleeve. One end of each locking rod away from the spring extends to the outside of the fixed locking block. Each locking rod is arranged in a horizontal U shape.

[0009] Further, fixed rods are fixed on the fixed locking block on the inner side of each locking rod. Each fixed rod is arranged in a shape like the Chinese character 'gan'. Auxiliary limiting blocks are rotatably sleeved between the two cross plates of each fixed rod. Hollow grooves cooperating with the auxiliary limiting blocks are formed in the middle of one end of each locking rod away from the fixed pin bar. The height of each fixed rod is less than the height of the auxiliary limiting block. Each auxiliary limiting block and the hollow groove are arranged in a rectangular shape.

[0010] Further, each unloading card slot is arranged in an arc shape cooperating with the milling cutter rod. The distance between the center of each unloading card slot and the end of the fixed pin bar is less than the distance between the center of the connecting groove and the inner wall of the fixed locking block.

[0011] Further, support shafts are fixed on both sides of one end of the assembly rotating plate close to the center of the loading disc. Each support shaft is rotatably connected to the side wall of the loading groove. Fixed grooves are formed on one side of each loading groove. A first servo motor is installed inside each fixed groove. The output end of each first servo motor is fixed to the support shaft close to the fixed groove side.

[0012] Further, the driving component includes a support turntable, a servo cylinder, a third servo motor and a driving sleeve. A support turntable is rotatably connected to the top surface of the loading disc. A support plate is fixed on the top surface of the support turntable. A servo cylinder is installed on one side of the support plate. One end of the output end of the servo cylinder slidably penetrates through the support plate and is fixed to a loading plate. A third servo motor is installed on one side of the loading plate away from the servo cylinder. The output end of the third servo motor is fixed to a driving sleeve.

[0013] Furthermore, the center of the output end of the third servo motor is on the same straight line as the center of the drive sleeve, and the vertical distance between the center of the output end of the drive sleeve and the center of the support shaft is equal to the vertical distance between the center of the milling cutter shank and the center of the support shaft.

[0014] Furthermore, a second servo motor is installed at the bottom of the loading tray. The output end of the second servo motor is rotatably connected to the loading tray. The center of the output end of the second servo motor is on the same straight line as the center of the circumference around which the loading slots are arranged. One end of the output end of the second servo motor, which extends through to the top surface of the loading tray, is fixed to the bottom surface of the support turntable.

[0015] Furthermore, both sides of the loading plate are slidably fitted with support slide rods, and both support slide rods are fixed on the side wall of the support plate. The drive sleeve has another connecting groove inside that cooperates with the milling cutter bar.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this invention, a plug-in limiting structure is used to limit the milling cutter shank during assembly by a fixing pin. When it is necessary to replace any milling cutter in the milling cutter assembly, the milling cutter can be removed by pressing the locking rod to replace it with another type of milling cutter, which greatly improves the convenience of milling cutter replacement during the machining process and saves more time and effort.

[0018] 2. In this invention, during the milling cutter's rotational cutting process, the centrifugal force acting outward causes the fixing pin to be placed more stably in the fixing slot, thereby making the connection between the milling cutter shank and the transfer plate more secure and stable.

[0019] 3. In this invention, the rotatable design of the mounting plate allows the milling cutter head to be rotated to be misaligned with the other milling cutter shanks during use. Then, the milling cutter shanks are connected to the drive sleeve to control the rotation of the milling cutter for cutting, thus avoiding the interference of other milling cutter heads with the cutting of the workpiece and ensuring the adaptability of the combined milling cutter.

[0020] 4. The automatic milling cutter design in this invention allows for automatic switching of the milling cutter according to the cutting requirements of the workpiece during the machining process, thereby achieving comprehensive machining of the workpiece. This makes the combined milling cutter more versatile and versatile, with a high degree of automation, ensuring machining efficiency. Attached Figure Description

[0030] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Example:

[0032] Reference Figures 1-7 A multi-purpose combination milling cutter includes a milling cutter head 1, a milling cutter shank 2, and a loading plate 3. Each milling cutter head 1 has a milling cutter shank 2 fixed to its top. The loading plate 3 has several loading slots 20 arranged in a circular pattern at equal intervals. Each loading slot 20 has a rotatable assembly plate 16 inside. Each assembly plate 16 is rotatably connected to a connecting sleeve 5 via a damping bearing. The damping bearing can be an oil film damping bearing. In the static state, the shaft and the bearing are in contact with static friction, requiring a large force to start. Once it starts rotating, an oil film forms, and the resistance decreases, thus ensuring that the connecting sleeve 5 will not rotate inside the assembly plate 16 under non-external force. This facilitates the alignment of the milling cutter shank 2 with the drive sleeve 28. Each connecting sleeve 5 contains a detachable milling cutter shank 2. A drive assembly is rotatably connected to the milling cutter head 1 to drive the milling cutter shank 2 to rotate.

[0033] In this embodiment, a fixing block 6 is fixed in the middle of the connecting sleeve 5. A set of fixing pins 8 are symmetrically slidably arranged inside the fixing block 6. Unloading slots 9 are opened on opposite sides of the two fixing pins 8. A spring 10 is fixed between the end of each fixing pin 8 near the center of the loading plate 3 and the inner wall of the fixing block 6. A fixing groove 12 that cooperates with the fixing pin 8 is opened on the side wall of each milling cutter bar 2 so that when the unloading slot 9 is misaligned with the milling cutter bar 2, the fixing pin 8 can limit the milling cutter bar 2. A locking rod 11 is fixed at the end of each set of two fixing pins 8 away from the spring 10. The locking rod 11 is slidably sleeved inside the fixing block 6.

[0034] When assembling the milling cutter shank 2, it needs to be stably connected to the connecting sleeve 5. Therefore, the milling cutter shank 2 is inserted into the connecting sleeve 5. The end of the milling cutter shank 2 away from the milling cutter head 1 is symmetrically provided with positioning grooves 4. The connecting sleeve 5 is provided with connecting grooves 7 that cooperate with the milling cutter shank 2 and the positioning grooves 4 to prevent the milling cutter shank 2 from rotating inside the connecting sleeve 5. The end of each milling cutter shank 2 away from the milling cutter head 1 extends to the outside of the connecting sleeve 5 to facilitate the connection between the milling cutter shank 2 and the drive sleeve 28. The end of each locking rod 11 away from the spring 10 extends to the outside of the fixed locking block 6. Each locking rod 11 is designed as a transverse U-shape to facilitate the movement of the two fixed pins 8 when the locking rod 11 is pressed.

[0035] In this embodiment, a fixing rod 13 is fixed on each fixing lock block 6 inside the lock rod 11. Each fixing rod 13 is arranged in a "dry" shape. An auxiliary limiting block 14 is rotatably sleeved between the two cross plates of each fixing rod 13. A hollow groove 15 cooperating with the auxiliary limiting block 14 is formed in the middle of each lock rod 11 far away from the end of the fixing pin 8. The height of each fixing rod 13 is less than the height of the auxiliary limiting block 14. Each auxiliary limiting block 14 and the hollow groove 15 are both rectangular. After the lock rod 11 is released, the outer side of the auxiliary limiting block 14 is fitted with the inner wall of the end of the lock rod 11. At this time, the auxiliary limiting block 14 is rotated to be misaligned with the hollow groove 15, so as to further limit the lock rod 11 and prevent the lock rod 11 from being accidentally pressed.

[0036] In this embodiment, each unloading card slot 9 is arranged in an arc shape cooperating with the milling cutter rod 2. The distance between the center of each unloading card slot 9 and the end of the fixing pin 8 is less than the distance between the center of the connecting slot 7 and the inner wall of the fixing lock block 6. Under the push of the spring 10, the center of gravity of the fixing pin 8 is located on the side of the center of gravity of the fixing lock block 6 far away from the spring 10, so that the fixing pin 8 can be stably fitted on the inner wall of the fixing lock block 6 on the side far away from the spring 10 under the push of the spring 10 and the centrifugal force of the rotation of the fixing lock block 6.

[0037] In this embodiment, support shafts 17 are fixed on both sides of the assembly turntable 16 close to the center of the loading disk 3. Each support shaft 17 is rotatably connected to the side wall of the loading slot 20. A fixing slot 19 is formed on one side of each loading slot 20. A first servo motor 18 is installed inside each fixing slot 19. The output end of each first servo motor 18 is fixedly connected to the support shaft 17 close to the fixing slot 19.

[0038] In this embodiment, the driving assembly includes a support turntable 22, a servo cylinder 24, a third servo motor 27, and a driving sleeve 28. The support turntable 22 is rotatably connected to the top surface of the loading plate 3. A support plate 23 is fixed to the top surface of the support turntable 22. A servo cylinder 24 is mounted on one side of the support plate 23. A loading plate 25 is fixed to one end of the servo cylinder 24, which slides through the support plate 23. A third servo motor 27 is mounted on the side of the loading plate 25 away from the servo cylinder 24. The driving sleeve 28 is fixed to the output end of the third servo motor 27. Supporting slide rods 26 are slidably sleeved on both sides of the loading plate 25. Both supporting slide rods 26 are fixed to the sidewalls of the support plate 23. The driving sleeve... The drive sleeve 28 has another connecting groove 7 that mates with the milling cutter shank 2. After the drive sleeve 28 is fitted onto the milling cutter shank 2, the third servo motor 27 drives the drive sleeve 28 to rotate, which in turn drives the milling cutter shank 2 to rotate. This drives the milling cutter head 1 to rotate for cutting. A transmitter and receiver of a through-beam laser sensor can be installed on the drive sleeve 28 and each milling cutter shank 2, respectively. After the milling cutter shank 2 rotates, the third servo motor 27 drives the drive sleeve 28 to rotate and align with the milling cutter shank 2. At this time, the transmitter and receiver are aligned on the same straight line. The receiver will receive the laser emitted by the transmitter, thereby generating an electrical signal to indicate that the alignment is complete.

[0039] To ensure that the milling cutter shank 2 can be aligned with the drive sleeve 28 when the assembly turntable 16 is rotated to the vertical position, so that the drive sleeve 28 and the milling cutter shank 2 can be connected, the center of the output end of the third servo motor 27 is on the same straight line as the center of the drive sleeve 28. The vertical distance between the center of the output end of the drive sleeve 28 and the center of the support shaft 17 is equal to the vertical distance between the center of the milling cutter shank 2 and the center of the support shaft 17.

[0040] During the cutting process, in order to adjust and replace the milling cutter shank 2 in the assembly, it is necessary to rotate the drive sleeve 28 so that the drive sleeve 28 is aligned with the milling cutter shank 2 to be used. A second servo motor 21 is installed at the bottom of the loading disk 3. The output end of the second servo motor 21 is rotatably connected to the loading disk 3. The center of the output end of the second servo motor 21 is on the same straight line as the center of the circumference of the loading groove 20. One end of the output end of the second servo motor 21 that extends through to the top surface of the loading disk 3 is fixed to the bottom surface of the support turntable 22.

[0041] Working principle: First, assemble the combination milling cutter. During assembly, select the milling cutter head 1 and milling cutter shank 2 according to the process requirements. Rotate the auxiliary limiting block 14 one by one until the auxiliary limiting block 14 is aligned with the hollow groove 15. After alignment, press the locking rod 11 so that the locking rod 11 pushes the fixing pin 8 to compress the spring 10 until the unloading slot 9 is aligned with the connecting groove 7. By controlling the length of the locking rod 11, when the outer locking rod 11 abuts against the fixing locking block 6, the unloading slot 9 is just aligned with the connecting groove 7. At this time, the limiting of the fixing pin 8 on the milling cutter shank 2 is released. Insert the milling cutter shank 2 into the connecting sleeve 5 so that the end of the positioning groove 4 abuts against the connecting sleeve 5. Then release the locking rod 11. At this time, the fixing pin 8 is pushed by the spring 10 and inserted into the fixing locking groove 12 to limit and fix the milling cutter shank 2, thereby completing the assembly of the milling cutter head 1 and the milling cutter shank 2 one by one.

[0042] After assembly, during the cutting process, the first servo motor 18 operates, driving the mounting plate 16 corresponding to the milling cutter head 1 to rotate via the support shaft 17. This rotates the milling cutter head 1 to be perpendicular to the other milling cutter heads 1, aligning the center of the milling cutter shank 2 with the center of the drive sleeve 28. At this time, the servo cylinder 24 operates, pushing the loading plate 25 towards the milling cutter shank 2, causing the drive sleeve 28 to be fitted onto the milling cutter shank 2, completing the docking of the milling cutter shank 2 and the drive sleeve 28. Simultaneously, the third servo motor 27 operates, driving the milling cutter shank 2 to rotate, and the loading plate 3... The mechanical drive structure drives the milling cutter head 1 to approach the workpiece for cutting. After the cutting is completed, when switching the milling cutter head 1, the third servo motor 27 stops running, the servo cylinder 24 runs and drives the drive sleeve 28 to separate from the milling cutter bar 2, the first servo motor 18 drives the milling cutter head 1 to rotate and reset, the second servo motor 21 runs and drives the support turntable 22 to rotate, so that the drive sleeve 28 is aligned with the next milling cutter head 1 to be used. The servo cylinder 24 and the first servo motor 18 corresponding to the next milling cutter head 1 to be used run, completing the docking of the drive sleeve 28 with the next milling cutter bar 2.
