Description

Technical Field

[0001] This invention relates to the field of milling cutter head technology, specifically a modular, interchangeable-blade composite milling cutter head. Background Technology

[0002] Modular interchangeable-edge compound milling cutter heads are advanced cutting tools that integrate modular design and rapid edge-changing technology. They have a wide range of applications, mainly in modern high-efficiency and high-precision CNC machining. Their main function is to quickly change cutting tools, reduce downtime, and adapt to various materials and machining requirements.

[0003] Traditional modular interchangeable-edge composite milling cutter heads mostly use threaded connections to fix the inserts. Although this structure can achieve basic positioning and fastening of the inserts, the inserts will vibrate violently during the cutting process, which can easily cause severe wear of the threaded pairs, creating a gap between the insert and the threaded post, and further aggravating abnormal wear of the inserts. Due to the uneven wear of each set of threads, the wear state of the inserts also varies, making it difficult to ensure that the extension length of each insert is consistent during subsequent insert compensation, ultimately affecting machining accuracy and machining stability. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides a modular, interchangeable-blade composite milling cutter head capable of individually compensating for wear on each set of blades to ensure consistent blade extension length.

[0005] To address the problems in existing technologies, this invention provides a modular, interchangeable-edge composite milling cutter disc, comprising a milling cutter disc body, a positioning assembly mounted on the milling cutter disc body, a cutting blade disposed inside an arc-shaped groove, the lower end of the cutting blade slidably connected to a groove opened in the arc-shaped groove, the upper end of the arc-shaped groove slidably connected to a groove opened in a threaded plate, the cutting blade being located between an infrared emitter and an infrared sensor, the infrared emitter being fixedly mounted at the lower end of a mounting bracket, and the infrared rays emitted by the infrared emitter being just blocked by the cutting blade (at this time, the cutting blade is in its initial installation position), used to detect whether the cutting blade needs compensation, the infrared sensor being fixedly mounted on a connecting bracket, the connecting bracket being located directly below the infrared emitter, capable of receiving the infrared rays emitted by the infrared emitter, an electric actuator being fixedly mounted on the inner wall of a slide rail, the output shaft of the electric actuator being fixedly connected to the side wall of the slider, capable of driving the cutting blade to move for compensation.

[0006] Specifically, a set of mounting brackets is fixedly installed on the main body of the milling cutter head, a set of connecting brackets is fixedly installed at the lower end of the main body of the milling cutter head, and multiple sets of arc-shaped grooves are opened on the upper part of the main body of the milling cutter head, with slide rails fixedly installed on the inner wall of the arc-shaped grooves.

[0007] Specifically, the slide rail has internal sliding connections with sliders, and a first connecting block is fixedly connected between two sets of sliders. The first connecting block and the cutting blade are fixedly connected by a nut, and the cutting blade is slidably connected to the groove inside the first connecting block.

[0008] Specifically, a set of threaded rods is rotatably connected to the arc-shaped groove. The upper end of the threaded rods is fixedly connected to the lower end of the rotating column. A set of threaded plates is threadedly connected to the threaded rods, and the threaded plates are slidably connected between two sets of slide rails.

[0009] Specifically, the milling cutter head body has multiple sets of mounting slots, and a set of rotating shafts is rotatably connected in the mounting slots. A set of spare cutting tools is fixedly connected to the outer wall of the rotating shafts. One end of the rotating shafts is fixedly connected to the output shaft of the first motor, which is installed inside the milling cutter head body.

[0010] Specifically, a shielding component is installed on the main body of the milling cutter head, and multiple sets of second connecting blocks are fixedly installed at the lower end of the main body of the milling cutter head. A drive shaft is rotatably connected between two sets of second connecting blocks. One end of the drive shaft is fixedly connected to the output shaft of a second motor. The second motor is fixedly installed on the side wall of the second connecting block, and a set of connecting plates is fixedly connected to the outer wall of the drive shaft.

[0011] Specifically, a set of arc-shaped plates is fixedly installed at the lower end of the connecting plate. A set of shielding grooves is opened on the side wall of the arc-shaped plates. A set of triangular blocks is fixedly connected to the lower end of the arc-shaped plates. After multiple sets of triangular blocks fit together, they will form a set of drilling cones. The locking arc-shaped plates are distributed around the pipe.

[0012] Specifically, a vacuum cleaner is installed on the main body of the milling cutter head. The inlet of the vacuum cleaner is fixedly connected to a pipe, which is fixedly installed inside the main body of the milling cutter head. The lower end of the pipe is fixedly connected to a dust collection hood.

[0013] The beneficial effects of this invention are: 1. In this invention, each set of infrared emitters corresponds to a set of cutting blades. The infrared rays emitted by the infrared emitters are blocked by the cutting blades and cannot be received by the infrared sensor. When the infrared sensor receives the infrared rays, it means that the cutting blades are severely worn and need to be compensated. At this time, the electric push rod will push the cutting blades to extend forward. When the infrared sensor can no longer receive the infrared rays, the electric push rod will stop immediately. This not only detects whether the cutting blades are severely worn, but also ensures that the length of the cutting blades extending to the outside of the milling cutter head body is consistent.

[0014] 2. In this invention, when the cutting blade is detected to be severely worn during the cutting process and has undergone multiple compensations, indicating that replacement is necessary, the electric actuator will immediately retract the cutting blade into the arc-shaped groove and stop the cutting operation. At the same time, the first motor will continue to drive the rotating shaft and the spare blade to rotate. After the spare blade rotates 90 degrees, its cutting surface extends to the cutting position of the cutting blade, thereby replacing the cutting blade for processing. After processing is completed, the cutting blade can be adjusted or replaced, which can effectively improve work efficiency.

[0015] 3. In this invention, the second motor can accommodate the spare blade inside the shielding groove during the cutting blade's operation, preventing debris generated during the cutting process from adhering to the cutting surface of the spare blade and affecting the subsequent use of the spare blade.

[0016] 4. In this invention, multiple sets of second motors are started, driving multiple sets of arc plates to rotate and move closer to each other. When multiple sets of triangular blocks are put together, they will form a set of drilling cones, which can meet the needs of workpiece drilling.

[0017] 5. In this invention, the vacuum cleaner can absorb the debris generated when the cutting blade is cutting, and while the triangular block is drilling, the generated debris will be sucked into the vacuum cleaner along the gap between the arc plates, thus preventing debris from flying.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Example 1: As Figure 1 , Figure 2 , Figure 5 as well as Figure 6 The modular, interchangeable-blade composite milling cutter disc shown includes a milling cutter disc body 1, a positioning assembly 2 mounted on the milling cutter disc body 1, a cutting blade 211 disposed inside an arc-shaped groove 210, the lower end of the cutting blade 211 slidably connected to a groove opened in the arc-shaped groove 210, and the upper end of the arc-shaped groove 210 slidably connected to a groove opened in a threaded plate 219. The cutting blade 211 is located between an infrared emitter 213 and an infrared sensor 215. The infrared emitter 213 is fixedly mounted on the lower end of a mounting bracket 212, and the infrared emitter 213 emits... The infrared light is blocked by the cutting blade 211 (at this time, the cutting blade 211 is in the initial installation position), which is used to detect whether the cutting blade 211 needs compensation. The infrared sensor 215 is fixedly installed on the connecting frame 214, which is located directly below the infrared transmitter 213 and can receive the infrared light emitted by the infrared transmitter 213. The electric push rod 226 is fixedly installed on the inner wall of the slide rail 216. The output shaft of the electric push rod 226 is fixedly connected to the side wall of the slider 217, which can drive the cutting blade 211 to move for compensation.

[0023] As described above, after the equipment is powered on, the mounting bracket 212 emits infrared rays. When the cutting blade 211 is not worn, it can just block the infrared rays from continuing to shine downwards. At this time, the infrared sensor 215 cannot receive the infrared rays emitted by the mounting bracket 212, which means that the cutting blade 211 does not need compensation at this time. Furthermore, the position where the infrared rays emitted by the mounting bracket 212 reach the upper end of the cutting blade 211 is 0.15 to 0.4 cm away from the cutting surface of the cutting blade 211. If the infrared rays emitted by the mounting bracket 212 are received by the infrared sensor 215... If the wear is severe, it means that the cutting insert 211 is severely worn and needs to be compensated; otherwise, the machining accuracy will be affected. At this time, the infrared sensor 215 will transmit the result to the control system (not shown) through the information transmitter (not shown). The control system will activate the electric push rod 226 to drive the cutting insert 211 to extend forward by 0.15 to 0.4 cm to compensate for the cutting insert 211. Each set of infrared emitters 213 and infrared sensors 215 corresponds to a set of cutting inserts 211, thereby independently detecting whether each set of cutting inserts 211 is worn and compensating accordingly. Note: If the wear of the cutting insert 211 is less than 0.15cm, no compensation is required, as this wear is negligible and will not affect the machining process.

[0024] Preferably, a set of mounting brackets 212 are fixedly installed on the milling cutter body 1, a set of connecting brackets 214 are fixedly installed at the lower end of the milling cutter body 1, and multiple sets of arc-shaped grooves 210 are opened on the upper part of the milling cutter body 1, with slide rails 216 fixedly installed on the inner wall of the arc-shaped grooves 210.

[0025] Preferably, the slide rail 216 has a slider 217 slidably connected inside, and a first connecting block 218 is fixedly connected between the two sets of sliders 217. The first connecting block 218 and the cutting blade 211 are fixedly connected by a nut, and the cutting blade 211 is slidably connected to the groove inside the first connecting block 218.

[0026] Mounting bracket 212 and connecting bracket 214 are used to mount infrared transmitter 213 and infrared sensor 215, keeping them at a distance from the cutting position of cutting blade 211 to avoid affecting the cutting operation. Arc groove 210 provides mounting position for cutting blade 211, and slide rail 216 can assist cutting blade 211 in compensation.

[0027] Preferably, a set of threaded rods 220 are rotatably connected to the arc groove 210. The upper end of the threaded rods 220 is fixedly connected to the lower end of the rotating column 221. A set of threaded plates 219 are threadedly connected to the threaded rods 220. The threaded plates 219 are slidably connected between the two sets of slide rails 216.

[0028] After the rotating column 221 is turned, it will drive the threaded rod 220 to rotate, thereby pushing the threaded plate 219 to slide. It can press against the upper end of the cutting blade 211 to form a limit for it. The threaded plate 219 can slide up and down, and at the same time adapt to various cutting blades 211 of different heights.

[0029] Preferably, the milling cutter body 1 has multiple sets of mounting slots 222, and a set of rotating shafts 224 are rotatably connected in the mounting slots 222. A set of spare cutting tools 225 are fixedly connected to the outer wall of the rotating shafts 224. One end of the rotating shafts 224 is fixedly connected to the output shaft of the first motor 223, and the first motor 223 is installed inside the milling cutter body 1.

[0030] If the cutting insert 211 is found to be severely worn during the cutting process and has undergone multiple compensations, and needs to be replaced, the first motor 223 can be started to drive the rotating shaft 224 to rotate 90 degrees in the forward direction, so that the cutting surface of the spare insert 225 moves to the same circumference as the cutting insert 211 and temporarily replaces the cutting insert 211 to perform the cutting work. When the workpiece has special processing requirements and the cutting angle needs to be changed, the first motor 223 can also be driven to rotate, and the rotation angle is determined according to the required cutting angle.

[0031] Example 2: Figure 1 , Figure 3 , Figure 4 as well as Figure 7 As shown, a shielding component 3 is installed on the main body 1 of the milling cutter disc. Multiple sets of second connecting blocks 310 are fixedly installed at the lower end of the main body 1 of the milling cutter disc. A set of transmission shafts 312 is rotatably connected between two sets of second connecting blocks 310. One end of the transmission shaft 312 is fixedly connected to the output shaft of the second motor 311. The second motor 311 is fixedly installed on the side wall of the connecting block 310. A set of connecting plates 313 is fixedly connected to the outer wall of the transmission shaft 312. A set of arc plates 314 is fixedly installed at the lower end of the connecting plate 313. A set of shielding grooves 315 are opened on the side wall of the arc plate 314. A set of triangular blocks 316 is fixedly connected to the lower end of the arc plate 314. After multiple sets of triangular blocks 316 are fitted together, they will form a set of drilling cones. The locking arc plates 314 are distributed around the pipe 111.

[0032] The second motor 311 can drive the arc plate 314 to rotate in the opposite direction during the operation of the cutting blade 211, so as to accommodate the spare blade 225 inside the shielding groove 315 (the arc plate 314 is shown in a vertical state in the figure to better show other parts), so as to prevent the chips generated during the cutting operation from sticking to the cutting surface of the spare blade 225 and affecting the subsequent use of the spare blade 225. When the workpiece needs to be drilled, the second motor 311 is started to drive the arc plate 314 to rotate in the forward direction. After multiple sets of triangular blocks 316 are put together, they will form a set of drilling cones to facilitate the drilling of the workpiece.

[0033] like Figure 1 as well as Figure 2 As shown, a vacuum cleaner 110 is provided on the upper part of the milling cutter body 1. The inlet of the vacuum cleaner 110 is fixedly connected to the pipe 111. The pipe 111 is fixedly installed inside the milling cutter body 1. The lower end of the pipe 111 is fixedly connected to the dust collection cover 112.

[0034] The vacuum cleaner 110 can absorb some of the debris generated during the cutting process of the cutting blade 211. Its main function is that when the triangular block 316 is used to make holes, the debris generated will be sucked into the vacuum cleaner 110 along the gap between the arc plates 314, thus preventing the debris from flying.

[0035] In this invention, the device is first powered on. At this time, multiple sets of infrared emitters 213 emit infrared rays to detect each set of cutting blades 211. If the infrared sensor 215 does not receive infrared rays, it indicates that the cutting blades 211 are not severely worn. However, if an infrared sensor 215 receives infrared rays, the control system will first issue a prompt on the display screen and compensate for the set of cutting blades 211 that are detected as severely worn. The control system will then activate the electric actuator 226, causing the cutting blades 211 to extend forward by 0.15–0.4 cm. After the compensation of the cutting blades 211 is completed, the control system will record the number of compensations (same as above). A single cutting insert 211 can undergo 2 to 4 compensations (depending on the distance of each compensation). After compensation is completed, the workpiece to be machined is fixed in the cutting position, and the equipment is started to machine the workpiece. When the cutting insert 211 is detected to be severely worn during the cutting process, and after multiple compensations, it needs to be replaced, the electric actuator 226 will immediately drive the cutting insert 211 to retract into the arc-shaped groove 210 and stop the cutting operation. At the same time, the first motor 223 will continue to drive the rotating shaft 224 and the spare insert 225 to rotate. After the spare insert 225 rotates 90 degrees, its cutting surface just extends to the cutting insert 211. The cutting position is adjusted to replace the cutting blade 211 for machining. After machining is completed, the cutting blade 211 is adjusted or replaced, which can effectively improve work efficiency. If there are special machining requirements for the workpiece and the cutting angle needs to be changed, the cutting blade 211 can be retracted into the arc groove 210, and the first motor 223 can drive the spare blade 225 to rotate. The rotation angle is determined according to the required cutting angle to meet the machining requirements. In addition, in this invention, the second motor 311 can drive the arc plate 314 to rotate in the opposite direction during the operation of the cutting blade 211, so as to accommodate the spare blade 225 into the shielding groove 315 and avoid... During the cutting process, the debris generated adheres to the cutting surface of the spare cutting tool 225, affecting the subsequent use of the spare cutting tool 225. When the workpiece needs to be drilled, the second motor 311 is started. The second motor 311 drives the transmission shaft 312 and the connecting plate 313 to rotate in the forward direction. The connecting plate 313 drives the arc plate 314 to rotate in the forward direction. During the rotation, when multiple sets of triangular blocks 316 come into contact with each other, they will form a set of drilling cones to facilitate drilling of the workpiece. During the drilling process, the debris generated by the drilling cones formed by the triangular blocks 316 will be sucked into the interior of the vacuum cleaner 110 along the gaps between the arc plates 314 to prevent debris from flying.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention.
