[0001] This invention relates to the field of parts cutting technology, specifically to a cutting and processing device for machining mechanical parts. Background Technology

[0002] In the field of mechanical manufacturing, cutting equipment is one of the key pieces of equipment for parts forming. With the popularization of CNC technology, modern cutting equipment has developed into high-precision, multi-axis linkage intelligent systems that integrate energy beam cutting technologies such as laser, plasma, and water jet, and achieve automated processing of complex contours through computer programming. For example, a five-axis linkage laser cutting machine can complete the precision cutting of three-dimensional curved surfaces of titanium alloy components in the aerospace field through dynamic focal length adjustment and real-time path optimization, while reducing thermal deformation.

[0003] Most existing materials used in manufacturing mechanical parts have uneven density, and current technologies may not be able to effectively address this uneven density, leading to vibrations during the cutting process and affecting cutting accuracy.

[0004] To address the above problems, a cutting and processing device for machining mechanical parts is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a cutting and processing device for machining mechanical parts. By using this device, the problem of uneven density in most existing materials used to manufacture mechanical parts, as mentioned above, is solved. Existing technologies may not be able to effectively deal with uneven material density, which can lead to vibration during the cutting process and affect cutting accuracy.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0008] Furthermore, the drive disk assembly includes a motor, which is fixedly connected to the cutting machine body. The output end of the motor is fixedly connected to an annular working cavity, and a protective cover is fixedly connected to the annular working cavity. A connecting disk is coaxially arranged with the annular working cavity, and the inner wall of the connecting disk is fixedly connected to the outer wall of the annular working cavity. The outer wall of the connecting disk is fixedly connected to the shearing disk assembly.

[0009] Furthermore, the hydraulic cooling drive assembly includes a hydraulic storage chamber, which is fixedly connected to an annular working chamber, and a gear pump is fixedly connected inside the hydraulic storage chamber.

[0010] Furthermore, the radial movement assembly includes a plurality of hydraulic cylinders, which are fixedly connected in the annular working chamber and arranged in a ring below the hydraulic storage chamber. A piston is slidably connected inside each hydraulic cylinder, and a dust cover is fixedly connected to the opening of each hydraulic cylinder.

[0011] Furthermore, the piston divides the cavity formed by the hydraulic cylinder and the dust cover into a left chamber and a right chamber. A spring is coaxially arranged with the hydraulic cylinder. One end of the spring is fixedly connected to the right side of the piston, and the other end of the spring is fixedly connected to the bottom of the right chamber. A connecting pipe is coaxially arranged with the hydraulic cylinder. One end of the connecting pipe is fixedly connected to the left side of the piston, and the connecting pipe is slidably connected to the dust cover.

[0012] Furthermore, the hydraulic cylinder has a port one and a port two. Port one is located in the position corresponding to the right chamber, and port two is located in the position corresponding to the left chamber. Solenoid valves are fixedly connected to both port one and port two. Annular pipe one and annular pipe two are fixedly connected inside the hydraulic storage chamber.

Annular pipe one has an interface one, and annular pipe two has an interface two. Interface two is connected to the output end of the gear pump through a hose.

[0013] Furthermore, a cooling port is provided on the connecting pipe, and the shearing disk assembly includes several T-shaped shape memory alloys.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1.

[0016] 2. The active cooling and dynamic avoidance mechanism reduces stress concentration in the shear disk assembly when cutting high-density abrupt change areas, thus reducing thermal damage and mechanical fatigue;

[0017] 3. The hydraulic cooling drive assembly combines coolant circulation and hydraulic drive functions, simultaneously achieving tool cooling and radial displacement control, simplifying the structure and improving energy efficiency. The motor, annular working chamber and connecting plate adopt a layered fixing method, which facilitates individual disassembly, maintenance or replacement, reducing maintenance costs.

[0018] 4. The circulation of liquid between the left chamber, right chamber and hydraulic storage chamber not only achieves active cooling of the connecting pipe and shear plate through the cooling port, but also optimizes energy utilization efficiency and reduces system power consumption by utilizing the spring energy storage and release mechanism.

[0019] 5. The radial movement distance of the fan-shaped shearing disc can be precisely controlled by adjusting the opening size of the solenoid valve. Combined with the thermal expansion characteristics of the shape memory alloy, thermal deformation during the cutting process is further compensated to ensure the stability of the cutting trajectory.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] A cutting and processing device for machining mechanical parts, referring to Figures 1-3 As shown, the machine includes a cutting machine body 1, on which a drive disk assembly 2 is fixedly connected. When cutting mechanical parts, the mechanical parts are first fixed to the cutting machine body 1 by a clamp (this is existing technology). After the mechanical parts are fixed, the drive disk assembly 2 is started, causing it to rotate. A shearing disk assembly 3 is coaxially arranged with the drive disk assembly 2 and is connected to the drive disk assembly 2 by transmission. When cutting mechanical parts, the drive disk assembly 2 rotates, thereby driving the shearing disk assembly 3, which is connected to it by transmission, to rotate synchronously, thus achieving the effect of the shearing disk cutting the mechanical parts. A torque sensor 4 is fixedly connected to the cutting machine body 1.

[0031] Reference Figures 3-5As shown, a hydraulic cooling drive assembly 5 is fixedly connected inside the drive disk assembly 2, and a radial moving assembly 6 is fixedly connected inside the drive disk assembly 2. The radial moving assembly 6 is connected to the hydraulic cooling drive assembly 5 and is driven by the shearing disk assembly 3. When cutting mechanical parts, the hydraulic cooling drive assembly 5 works, that is, the hydraulic cooling drive assembly 5 cools the drive disk assembly 2 and the shearing disk assembly 3 by circulating coolant. Since the density of most materials used to make mechanical parts is not uniform, when the shearing disk assembly 3 cuts the mechanical parts, the torque of the drive disk assembly 2 will fluctuate when the shearing disk assembly 3 cuts to the critical position of two different density regions. Therefore, when the torque sensor 4 detects the fluctuation of the torque of the drive disk assembly 2, it transmits the monitoring information to the controller. The controller is existing technology and is not shown in the figure. The controller controls the hydraulic cooling drive assembly 5 to work, and the radial moving assembly 6 pushes the shearing disk assembly 3 to move away from the axis through hydraulic action.

[0032] The torque sensor 4 monitors the torque fluctuation of the drive disk assembly 2 in real time. Combined with the linkage of the hydraulic cooling drive assembly 5 and the radial movement assembly 6, the radial position of the shear disk assembly 3 is automatically adjusted when cutting to critical areas of different densities. This effectively reduces cutting vibration or tool wear caused by uneven material density, improving cutting accuracy and stability. At the same time, the hydraulic cooling drive assembly 5 has both coolant circulation and hydraulic drive functions, simultaneously achieving tool cooling and radial displacement control, simplifying the structure and improving energy efficiency. The active cooling and dynamic avoidance mechanism reduces stress concentration of the shear disk assembly 3 when cutting high-density abrupt change areas, reducing thermal damage and mechanical fatigue.

[0033] Reference Figures 1-3 As shown, the drive disk assembly 2 includes a motor 21, which is fixedly connected to the cutting machine body 1. The output end of the motor 21 is fixedly connected to an annular working cavity 22, and a protective cover 23 is fixedly connected to the annular working cavity 22. When cutting mechanical parts, the motor 21 is started, causing the motor 21 to drive the annular working cavity 22 and the protective cover 23 to rotate synchronously. A connecting disk 24 is coaxially arranged with the annular working cavity 22. The inner wall of the connecting disk 24 is fixedly connected to the outer wall of the annular working cavity 22. When the annular working cavity 22 rotates with the motor 21, it drives the connecting disk 24 fixedly connected to it to rotate synchronously. The outer wall of the connecting disk 24 is fixedly connected to the shearing disk assembly 3. The rotation of the connecting disk 24 drives the shearing disk assembly 3 to rotate, thereby cutting the mechanical parts. The motor 21, the annular working cavity 22 and the connecting disk 24 are fixed in layers, which facilitates individual disassembly, inspection or replacement, and reduces maintenance costs.

[0034] Reference Figures 1-4As shown, the hydraulic cooling drive assembly 5 includes a hydraulic storage chamber 51, which is fixedly connected to the annular working chamber 22. The hydraulic storage chamber 51 is filled with liquid, and a gear pump 52 is fixedly connected inside the hydraulic storage chamber 51. The gear pump 52 operates when cutting mechanical parts.

[0035] Reference Figures 5-8 As shown, the radial moving assembly 6 includes several hydraulic cylinders 61, which are fixedly connected in the annular working chamber 22. The hydraulic cylinders 61 are arranged in a ring below the hydraulic storage chamber 51. A piston 62 is slidably connected inside the hydraulic cylinder 61, and a dust cover 63 is fixedly connected to the opening of the hydraulic cylinder 61.

[0036] The piston 62 divides the cavity formed by the hydraulic cylinder 61 and the dust cover 63 into a left chamber 64 and a right chamber 65. A spring 66 is coaxially arranged with the hydraulic cylinder 61. One end of the spring 66 is fixedly connected to the right side of the piston 62, and the other end of the spring 66 is fixedly connected to the bottom of the right chamber 65. The spring 66 is located inside the right chamber 65. A connecting pipe 67 is coaxially arranged with the hydraulic cylinder 61. One end of the connecting pipe 67 is fixedly connected to the left side of the piston 62, and the connecting pipe 67 is slidably connected to the dust cover 63. Both the left chamber 64 and the right chamber 65 are filled with liquid.

[0037] The hydraulic cylinder 61 has a port 1 611 and a port 2 612. Port 1 611 is located in the right chamber 65, and port 2 612 is located in the left chamber 64. Solenoid valves 613 are fixedly connected to both ports 1 611 and 2 612. Annular pipes 1 511 and 2 512 are fixedly connected inside the hydraulic storage chamber 51. Annular pipe 1 511 is connected to the solenoid valve 613 fixedly connected to port 1 611, and annular pipe 2 512 is connected to the solenoid valve 613 fixedly connected to port 2 612. Annular pipe 1 511 has an interface 1 5111, and annular pipe 2 512 has an interface 2 5121. Interface 2 5121 is connected to the output end of the gear pump 52 via a hose. When the shearing disc assembly 3 cuts to the critical region of different densities, the torque sensor 4 monitors the torque fluctuation of the drive disc assembly 2. At this time, the solenoid valve located at port 2 612... When valve 613 is opened, solenoid valve 613 located at port 611 also opens. Under the action of gear pump 52, the liquid in hydraulic storage chamber 51 enters left chamber 64 through annular pipe 512 and port 612, increasing the hydraulic pressure in left chamber 64. This causes piston 62 to move to the right, reducing the volume of right chamber 65 and compressing spring 66. Liquid in right chamber 65 then enters hydraulic storage chamber 51 through port 611, annular pipe 511, and interface 5111. Afterward, gear pump 52 reverses, pumping the liquid in left chamber 64 back into hydraulic storage chamber 51. During this process, the hydraulic pressure in left chamber 64 decreases. Under the action of spring 66, piston 62 moves to the left, increasing the volume of right chamber 65. Under negative pressure, the liquid in hydraulic storage chamber 51 re-enters right chamber 65, thus causing piston 62 to reciprocate.

[0038] A cooling port 671 is provided on the connecting pipe 67. When the piston 62 moves back and forth, that is, when the torque sensor 4 detects the torque fluctuation of the drive disk assembly 2, the liquid is made to flow back and forth between the left chamber 64 and the hydraulic storage chamber 51 by the action of the gear pump 52. Since the cooling port 671 is exposed in the left chamber 64, the liquid in the connecting pipe 67 can flow synchronously, thereby producing a cooling effect.

[0039] The shearing disc assembly 3 includes several T-shaped shape memory alloys 31. One end of each T-shaped shape memory alloy 31 is fixedly connected to the outer edge of the connecting disc 24. The T-shaped shape memory alloys 31 are arranged in a ring. The outer edge of the connecting disc 24 is also arranged in a ring with several fan-shaped shearing discs 32. The fan-shaped shearing discs 32 are provided with T-shaped connecting grooves 321. The T-shaped shape memory alloys 31 are fixedly connected in the T-shaped connecting grooves 321. The T-shaped shape memory alloys 31 are fixedly connected to the other end of the connecting pipe 67. The connecting disc 24 is slidably connected to the connecting pipe 67. When the piston 62 moves back and forth, it drives the T-shaped shape memory alloys 31 and the fan-shaped shearing discs 32 to move back and forth synchronously, so that the fan-shaped shearing discs 32 move radially back and forth. At the same time, the opening size of the solenoid valve 613 can be controlled, thereby achieving the purpose of controlling the radial movement distance of the fan-shaped shearing discs 32. During the cutting of mechanical parts, due to the friction between the fan-shaped shearing discs 32 and the mechanical parts, the temperature of the T-shaped shape memory alloys 31 rises, thereby causing the shape memory alloys to elongate.

[0040] Torque sensor 4 monitors torque fluctuations in drive disk assembly 2 in real time. It controls the direction of liquid flow through solenoid valve 613, driving piston 62 to reciprocate. This causes T-shaped shape memory alloy 31 and fan-shaped shear disk 32 to adjust radially, automatically adapting to areas of sudden changes in material density, reducing cutting vibration and tool wear, and improving processing accuracy. The circulation of liquid between left chamber 64, right chamber 65, and hydraulic storage chamber 51 not only achieves active cooling of connecting pipe 67 and shear disk through cooling port 671, but also optimizes energy utilization efficiency and reduces system power consumption through the energy storage and release mechanism of spring 66. The radial movement distance of fan-shaped shear disk 32 can be precisely controlled by adjusting the opening size of solenoid valve 613. Combined with the thermal expansion characteristics of shape memory alloy, it further compensates for thermal deformation during the cutting process, ensuring the stability of the cutting trajectory.
