Description

Technical Field

[0001] The present invention relates to the technical field of earthquake-resistant technology for construction engineering, and more specifically to an efficient cutting device for earthquake-resistant support hangers. Background Art

[0002] A disk cutting machine is a cutting device with a rotating disk blade as the core component, widely used in fields such as metal processing, stone mining, and building material manufacturing. Its working principle is to drive the blade to rotate at high speed through a motor, and combine with a feeding system to achieve precise cutting of materials. When applied to the cutting of earthquake-resistant brackets, it needs to be configured specifically in combination with the material characteristics of the earthquake-resistant brackets, cutting accuracy requirements, and safety protection measures; Earthquake-resistant brackets mostly use metal materials such as steel and stainless steel. Carbide or high-speed steel knives need to be selected. During the cutting process, due to excessive strength, the disk knife blade deviates, and the burrs on the cut increase, affecting the processing quality of precision components such as earthquake-resistant support hangers; Traditional braking means rely on sensors or algorithms to predict dangerous working conditions, and only use manual triggering for braking. Moreover, the impact force during emergency stops of general braking means is likely to cause deformation of the main shaft or tooth breakage of the gears in the transmission system, and the reset time after braking is long, affecting the continuous operation process and resulting in reduced production efficiency. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides an efficient cutting device for earthquake-resistant support hangers to solve the problems existing in the above background art.

[0004] The present invention provides the following technical solutions: An efficient cutting device for earthquake-resistant support hangers includes a straight arm, a rotating arm, a turntable, a main rotating shaft, and a disk knife, and further includes: One end of the straight arm is rotatably connected to the rotating arm, the end of the rotating arm away from the straight arm is fixedly connected to the turntable, a main rotating shaft is arranged in the exact middle of the turntable, a sleeve is movably connected to the outside of the main rotating shaft through a bearing, a vibration suppression and offset braking mechanism is arranged on the outside of the sleeve, and a disk knife is fixedly connected to the side of the main rotating shaft away from the turntable.

[0005] Further, the rotating arm makes a circular motion around the turntable, adopts multi-axis linkage, realizes the rotation of the rotating arm through gear transmission, has high degrees of freedom and motion capabilities, and can achieve complex trajectory cutting through the combined motion of the turntable and the rotating arm. The straight arm is composed of multiple joints in series, equipped with independent drive motors, and high-precision transmission is achieved between the joints through RV reducers.

[0006] Further, a magnet ring is embedded in the center of the disk knife. The radial cross-section of the magnet ring is trapezoidal and closely fits the circumference of the disk to reduce the magnetic pole gap.

[0007] Further, six magnetic drive mechanisms are evenly arranged on the outer surface of the bottom of the sleeve near one side of the disc cutter. An annular support mechanism is movably connected in the middle of the magnetic drive mechanism. A vibration suppression mechanism is fixedly connected to the magnetic drive mechanism. A braking mechanism is fixedly connected to the top of the vibration suppression mechanism.

[0008] Further, the vibration feedback of the equipment can be divided into four parts. The first part is the magnetic drive mechanism, which can collect the vibration offset generated by the disc cutter and amplify it for use in the vibration suppression mechanism and the braking mechanism. In the braking mechanism, the offset generated by the vibration is used for emergency braking. In the vibration suppression mechanism, the received vibration is reduced and weakened by hydraulic means.

[0009] Further, six mechanical claw tips are evenly distributed on the outer surface of the bottom of the sleeve near one side of the disc cutter. A transmission rod is fixedly connected to the top of the mechanical claw tip. A pair of meshing planetary gear sets are arranged on the side of the transmission rod close to the sleeve through gears. A centripetal gear mechanism is arranged at the bottom of the planetary gear sets. A centripetal sliding groove is arranged at the bottom of the planetary gear sets through gear meshing. A gear plate is arranged on the outer side of the bottom of the centripetal sliding groove; A vibration suppression mechanism is fixedly connected to the top of the centripetal sliding groove. A braking mechanism is fixedly connected to the top of the vibration suppression mechanism.

[0010] Further, magnets that generate magnetic repulsion with the disc cutter are also embedded in the mechanical claw tips.

[0011] Further, when the disc cutter generates an offset under the thrust of the item to be cut during operation, the magnet therein will generate a magnetic repulsion force on the mechanical claw tips, thereby pushing the mechanical claw tips to move upward. In this process, the transmission rod provided with gears will also move upward synchronously with the mechanical claw tips, which can drive the rotation of the planetary gear sets. Then, through the meshing of the gears of the centripetal gear mechanism, it drives the further movement of the vibration suppression mechanism. In the whole process, the planetary gear sets convert the tiny deformation generated by the disc cutter on one side of the main rotating shaft into a larger form of deformation, and suppress and utilize it in the subsequent structure.

[0012] Further, support rods are respectively fixedly connected to both sides of the vibration suppression mechanism through sleeves. A small annular rod is fixedly connected to the side of the support rod close to the main rotating shaft. Six inner circular rods are evenly distributed on the small annular rod. The other side of the support rod is fixedly connected to a large annular rod. Six outer circular rods are evenly distributed at the positions corresponding to the inner circular rods on the large annular rod.

[0013] Further, the large annular rod, the small annular rod and the support rod play a role of a framework. Six groups of planetary gear sets are evenly arranged on them, setting their movements in specified positions, and only playing a role of amplifying deformation.

[0014] Furthermore, a fixed slider is fixedly connected to one side of the top of the centripetal gear mechanism away from the planetary gear set. An inclined slider is fixedly connected to the inclined surface of the top of the fixed slider. A braking mechanism is fixedly connected to one side of the top of the inclined slider close to the planetary gear set, and a hydraulic mechanism is fixedly connected to the other side of the top of the inclined slider.

[0015] Furthermore, a thin straight rod is fixedly connected to one side of the top of the inclined slider away from the planetary gear set. A support rod is fixedly connected to the center of the top of the thin straight rod. A blocking disc is fixedly connected to the top of the support rod, and an oil cavity is arranged outside the blocking disc.

[0016] Furthermore, for the centripetal gear mechanism, when deformation is transmitted to the centripetal gear mechanism, it converts it into two parts. One part is transmitted to the vibration suppression mechanism for suppression. The advancement of the centripetal gear mechanism drives the fixed slider thereon. The inclined surface of the centripetal gear mechanism squeezes the inclined slider, causing the upward movement of the hydraulic mechanism. The other part is transmitted to the braking mechanism for utilization. The inclined slider is forced to move upward under extrusion, transmitting the force to the outer pushing frame. Under the restriction of the structural limiting ring, the outer pushing frame will drive a part of the main rotating shaft structure to move upward, resulting in the disc cutter and a part of the main rotating shaft being disconnected from the motor to perform offset protection.

[0017] Furthermore, an outer pushing frame is fixedly connected to the top of the inclined slider, and a limiting ring is arranged on one side of the outer pushing frame away from the centripetal gear mechanism.

[0018] Furthermore, two small holes are arranged on the blocking disc.

[0019] Technical effects and advantages of the present invention: 1. By providing a magnetic drive mechanism, the magnet ring at the center of the disc cutter and the magnets inside the mechanical claw tips form a magnetic repulsion force array in the present invention, which can perform real-time displacement monitoring. When the blade starts to offset, subsequent actions can be triggered for vibration suppression and subsequent utilization of force. Moreover, the action range of the magnetic repulsion force is adjustable, which can adapt to the cutting requirements of various anti-seismic support materials.

[0020] 2. By providing a vibration suppression mechanism, two small holes are added to the design of the blocking disc in the oil cavity in the present invention. The small hole diameters are like making the oil pass through finer "needles", which requires greater force to push, thereby consuming more vibration energy, increasing the viscous damping coefficient, and absorbing more than 85% of the impact kinetic energy, reducing the vibration amplitude of the tool.

[0021] 3. By providing a braking mechanism, the present invention makes full use of the vibration displacement generated by the equipment. After being amplified by the planetary gear set, the force is converted into the power of the braking mechanism and will be triggered when reaching a certain threshold. It does not rely on manual operation and will not generate a large impact force on the main shaft and the transmission system, effectively extending the service life of the equipment.

Detailed Description of the Invention

[0032] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples, and the high-efficiency cutting equipment for seismic support hangers involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained without creative efforts by those skilled in the art belong to the scope of protection of the present invention.

[0033] Referring to Figure 1 , the present invention provides a high-efficiency cutting equipment for seismic support hangers, including a straight arm 1, a rotating arm 2, a turntable 3, a main rotating shaft 6 and a circular saw blade 5, and further including: one end of the straight arm 1 is rotatably connected to the rotating arm 2, the end of the rotating arm 2 far from the straight arm 1 is fixedly connected to the turntable 3, a main rotating shaft 6 is arranged in the exact middle of the turntable 3, the outer side of the main rotating shaft 6 is movably connected with a sleeve 7 through a bearing, a vibration suppression offset braking mechanism 4 is arranged on the outer side of the sleeve 7, and the circular saw blade 5 is fixedly connected to the side of the main rotating shaft 6 far from the turntable 3.

[0034] Referring to Figure 1 , the rotating arm 2 makes a circular motion around the turntable. By adopting multi-axis linkage and gear transmission, the rotating arm 2 can achieve a 360° rotation, with high degrees of freedom and motion ability. It can realize complex trajectory cutting through the combined motion of the turntable and the rotating arm 2. The straight arm 1 is composed of multiple joints in series, equipped with an independent drive motor, and high-precision transmission is achieved between the joints through an RV reducer.

[0035] Referring to Figure 1 , a magnet ring is embedded in the center of the circular saw blade 5. The radial cross-section of the magnet ring is trapezoidal and closely fits the circumference of the disc to reduce the magnetic pole gap.

[0036] Referring to Figure 2 , six magnetic drive mechanisms 401 are evenly arranged on the outer surface of the bottom of the sleeve 7 near the circular saw blade 5. An annular support mechanism 403 is movably connected in the middle of the magnetic drive mechanisms 401. A vibration suppression mechanism 402 is fixedly connected to the magnetic drive mechanisms 401, and a braking mechanism 404 is fixedly connected to the top of the vibration suppression mechanism 402.

[0037] Referring to Figure 2 , the vibration feedback of the equipment is divided into four parts. The first part is the magnetic drive mechanism 401, which can collect the vibration offset generated by the circular saw blade 5 and amplify it for use in the vibration suppression mechanism 402 and the braking mechanism 404. In the braking mechanism 404, emergency braking is carried out by borrowing the offset generated by the vibration, and in the vibration suppression mechanism 402, the received vibration is reduced and weakened by hydraulic means.

[0038] Referring to Figure 2 and Figure 3, on the outer surface of one side of the bottom of the sleeve 7 close to the disc cutter 5, six mechanical claw tips 4011 are evenly distributed. The top of the mechanical claw tip 4011 is fixedly connected to a transmission rod 4012. On one side of the transmission rod 4012 close to the sleeve 7, a pair of meshing planetary gear sets 4013 are arranged through gears. At the bottom of the planetary gear set 4013, a centripetal gear mechanism 4014 is arranged. The bottom of the planetary gear set 4013 is provided with a centripetal chute 40141 through gear meshing. On the outer side of the bottom of the centripetal chute 40141, a gear plate 40142 is arranged; the top of the centripetal chute 40141 is fixedly connected to a vibration suppression mechanism 402, and the top of the vibration suppression mechanism 402 is fixedly connected to a braking mechanism 404.

[0039] Refer to Figure 2 and Figure 3 , six groups of evenly distributed mechanical claw tips 4011 are arranged. During the rotation of the disc cutter 5, the mechanical claw tips 4011 can completely cover the cutter surface of the entire disc cutter 5. No matter which direction there is an offset or skew, it can be sensed and corrected in the first time. The mechanical claw tips 4011 capture the displacement through magnetic repulsion, transmit it to the planetary gear set 4013 for displacement amplification, and then transmit it to the vibration suppression mechanism 402 and the braking mechanism 404 for reuse.

[0040] Refer to Figure 3 , magnets that generate magnetic repulsion with the disc cutter 5 are also embedded in the mechanical claw tips 4011.

[0041] Refer to Figure 2 and Figure 3 , when the disc cutter 5 is pushed by the item to be cut during operation and thus generates an offset, the magnets therein will generate magnetic repulsion on the mechanical claw tips 4011, thereby pushing the mechanical claw tips 4011 to move upward. In this process, the transmission rod 4012 provided with gears will also move upward synchronously with the mechanical claw tips 4011, which can push the planetary gear set 4013 to rotate. Then, through the meshing of the gears of the centripetal gear mechanism 4014, it drives the further movement of the vibration suppression mechanism 402. In the whole process, the planetary gear set 4013 converts the small deformation generated by the disc cutter 5 on one side of the main rotating shaft 6 into a larger form of deformation, and suppresses and utilizes it in the subsequent structure.

[0042] Refer to Figure 4 , both sides of the vibration suppression mechanism 402 are fixedly connected to a support rod 4035 through the sleeve 7 respectively. On one side of the support rod 4035 close to the main rotating shaft 6, a small ring rod 4034 is fixedly connected. Six inner round rods 4032 are evenly distributed on the small ring rod 4034. On the other side of the support rod 4035, a large ring rod 4033 is fixedly connected. At the positions corresponding to the inner round rods 4032 on the large ring rod 4033, six outer round rods 4031 are evenly distributed.

[0043] Refer to Figure 4 , the large ring rod 4033, the small ring rod 4034 and the support rod 4035 play the role of a skeleton, on which six groups of planetary gear sets 4013 are evenly arranged, and their movements are set at specified positions, only playing the role of amplifying deformation.

[0044] Refer to Figure 5 , on the side of the top of the centripetal gear mechanism 4014 away from the planetary gear set 4013, a fixed slider 4021 is fixedly connected, on the top inclined surface of the fixed slider 4021, an inclined slider 4022 is fixedly connected, on the side of the top of the inclined slider 4022 close to the planetary gear set 4013, a braking mechanism 404 is fixedly connected, and on the other side of the top of the inclined slider 4022, a hydraulic mechanism 4023 is fixedly connected.

[0045] Refer to Figure 5 , the shapes and sizes of the fixed slider 4021 and the inclined slider 4022 match each other, converting the displacement in the horizontal direction into the displacement in the vertical direction. While pushing the inclined slider 4022 to move upward along the sleeve 7, it also promotes the further movement of the braking mechanism 404 and the hydraulic mechanism 4023.

[0046] Refer to Figure 6 , on the side of the top of the inclined slider 4022 away from the planetary gear set 4013, a thin straight rod 40231 is fixedly connected, at the center of the top of the thin straight rod 40231, a support rod 40232 is fixedly connected, at the top of the support rod 40232, a blocking disc 40233 is fixedly connected, and an oil cavity 40234 is arranged outside the blocking disc 40233.

[0047] Refer to Figure 7 , on the top of the inclined slider 4022, an outer push frame 4041 is fixedly connected, and a limit ring 4042 is arranged on the side of the outer push frame 4041 away from the centripetal gear mechanism 4014.

[0048] Refer to Figure 7 and Figure 8 , when the deformation is transmitted to the centripetal gear mechanism 4014, it is converted into two parts again. One part is transmitted to the vibration suppression mechanism 402 for suppression. The advancement of the centripetal gear mechanism 4014 drives the fixed slider 4021 thereon, and the inclined surface of the centripetal gear mechanism 4014 squeezes the inclined slider 4022, causing the upward movement of the hydraulic mechanism 4023. The other part is transmitted to the braking mechanism 404 for utilization. The inclined slider 4022 is forced to move upward under extrusion, transmitting the force to the outer push frame 4041. Under the limitation of the structural limit ring 4042, the outer push frame 4041 will drive a part of the main rotating shaft 6 structure to move upward, so that the disc cutter 5 and a part of the main rotating shaft 6 will be disconnected from the motor for offset protection.

[0049] Among them, two small holes are provided on the blocking disk 40233.

[0050] The working principle of the present invention: When the motor is turned on and the device is operating normally, the straight arm 1 drives the circular cutter 5 to move up and down to cut the required items. When encountering items with special shapes or high strength, the circular cutter 5 will be deflected by the thrust. The magnet therein will generate a magnetic repulsive force on the corresponding mechanical claw tip 4011 as the circular cutter 5 moves, thus pushing the mechanical claw tip 4011 to move upward. In this process, the transmission rod 4012 provided with gears will also move upward synchronously with the mechanical claw tip 4011. And under the meshing movement of the gears, the small displacement in the vertical direction is converted into a large displacement in the horizontal direction by the planetary gear set 4013 and is suppressed and utilized in the subsequent structure. Then, through the mutual movement of the planetary gear set 4013 and the centripetal gear mechanism 4014, the fixed slider 4021 is driven to move towards the direction close to the main rotating shaft 6. The inclined surface of the fixed slider 4021 presses the inclined slider 4022 upward, so that the braking mechanism 404 and the hydraulic mechanism 4023 provided on the inclined slider 4022 can utilize the force thereon to suppress and utilize the displacement. The thin straight rod 40231 pushes the support rod 40232 and the blocking disk 40233 to move in the vertical direction in the oil cavity 40234. Two small holes are provided on the blocking disk 40233. When the oil in the oil cavity 40234 passes through, the viscous friction increases and generates a resistance to hinder the upward movement of the blocking disk 40233, thereby playing a role in suppressing the deflection of the circular cutter 5. The braking mechanism 404 on the side of the inclined slider 4022 close to the main rotating shaft 6 utilizes the transmitted displacement. The upward movement of the inclined slider 4022 will drive the upward movement of the outer push frame 4041 thereon. The outer push frame 4041 is restricted by the limit ring 4042 and will drive the limit ring 4042 and a part of the main rotating shaft 6 fixedly connected to the limit ring 4042 to move upward. The main rotating shaft 6 is divided into two parts. One part of the main rotating shaft 6 close to the turntable 3 is connected to the motor, and the other part will lose the power source after being separated, playing a role in offset braking.

[0051] Finally: The above description is only a preferred embodiment of the present invention and is not used to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
