Description

Technical Field

[0001] The invention relates to the technical field of machine tool processing, in particular to a mechanical arm cutting machine for manufacturing industrial automatic control devices. Background Art

[0002] With the continuous development of modern mechanical processing industry, the market requirements for cutting quality and precision are becoming increasingly stringent. At the same time, in order to stand out in the fierce competition, enterprises are increasingly in need of improving production efficiency, reducing production costs, and equipping with highly intelligent automatic cutting functions. Among many automated equipment, the robotic arm has become the most widely used automated mechanical device due to its excellent performance. It can accurately locate any point in three-dimensional (or two-dimensional) space to complete various complex tasks. The robotic arm cutting machine is an important branch of robotic arm applications. Its biggest advantage is that the cutting angle can be flexibly controlled and set through the control system. This feature not only makes the operation more convenient, but also greatly broadens its scope of application, and can meet the cutting needs of different industries and different scenarios.

[0003] After extensive searching, the publication number is CN117066909B, which discloses a robotic arm cutting machine for manufacturing industrial automatic control devices, including a moving seat, a steel pipe body, a supporting mechanism, a robotic arm body and a cutting and grinding mechanism, wherein the supporting mechanism includes a supporting frame and a supporting bracket.

[0004] When the device in the existing technology is in use, a cutting disc and a grinding disc are set. Since the grinding disc has a structure that is thick in the middle and thin at the edges, the edge of the grinding disc just enters the incision of the outer wall of the steel pipe body, and the surface of the grinding disc is made of frosted material, and its edge is used to grind the cut surface of the steel pipe body to effectively remove small debris remaining from the cutting. Secondly, both sides of the grinding disc have curved surfaces, which are used to grind the edge of the outer surface of the steel pipe body, so that the edge of the steel pipe body can be polished while the steel pipe body is cut.

[0005] When the above device is actually used, the steel pipe needs to be clamped by a supporting mechanism. However, since the size of the supporting mechanism is fixed, only steel pipes of a single size can be clamped. As a result, steel pipes of different sizes need to be clamped by replacing the supporting mechanism, which reduces work efficiency. At the same time, since a fixed plate with a limiting function is provided, the length of the steel pipe that can be processed is also limited, resulting in great limitations in the use of the device. Therefore, a robotic arm cutting machine for manufacturing industrial automatic control devices is proposed to solve the above problems. Summary of the invention

[0016] Preferably, the number of the clamping assemblies is two. Installation holes are opened at the bottoms of the bases of the two clamping assemblies, and the two clamping assemblies are respectively tightly installed through the installation bolts passing through the installation holes and the threaded holes opened on the upper end face of the bottom plate on both sides of the chip discharge groove. A bar body is clamped by the two clamping assemblies directly above the chip discharge groove.

[0017] When the above technical solution is adopted, the two clamping assemblies are respectively tightly installed on the bottom plate on both sides of the chip discharge groove through the installation bolts. The installation method is simple and firm, and can stably support and fix the clamping assemblies; a bar body is clamped by the two clamping assemblies directly above the chip discharge groove. This layout enables the chips generated during the cutting process to directly fall into the chip discharge groove, avoiding the accumulation of chips in the working area and affecting the cutting operation. At the same time, it is also convenient for centralized cleaning of the chips and ensures a clean working environment.

[0018] Preferably, the first driven roller and the second driven roller are located on the same vertical line, the first driven roller and the second driven roller are of matching sizes and are both designed with stainless steel materials. The circumferential surfaces of the first driven roller and the second driven roller are in contact with the outer wall of the bar body but not fixedly connected. Anti-slip patterns parallel to the bar body are provided on the outer walls of the first driven roller and the second driven roller. The first driven roller is located directly below the second driven roller.

[0019] When the above technical solution is adopted, the first driven roller and the second driven roller are located on the same vertical line and are of matching sizes, which can uniformly clamp the bar body and prevent the bar body from shifting during the cutting process due to uneven force; the driven rollers designed with stainless steel materials have good wear resistance and corrosion resistance, which can extend the service life; the circumferential surfaces of the driven rollers are in contact with the outer wall of the bar body but not fixedly connected, which can ensure effective clamping of the bar body without affecting the rotation of the bar body; the anti-slip patterns provided on the outer walls increase the friction with the bar body, improve the stability of clamping, and prevent the bar body from slipping during the cutting process.

[0020] Preferably, the number of the adjusting cylinders is two. The two adjusting cylinders are respectively fixedly installed on both sides of the clamping seat by bolts. The top telescopic ends of the two adjusting cylinders are respectively fixedly connected to both sides of the top frame by welding. The top frame is fixedly installed on the opposite side of the two adjusting cylinders.

[0021] When the above technical solution is adopted, the two adjusting cylinders are respectively fixedly installed on both sides of the clamping seat and the top telescopic ends are welded and fixed to both sides of the top frame, so that the top frame is evenly stressed during the lifting process and can smoothly adjust the height of the second driven roller, thereby better adapting to the clamping requirements of bar bodies with different diameters, and improving the versatility and adaptability of the equipment.

[0022] Preferably, the bottom of the sliding frame is slidably fitted with a chute opened at the inner bottom of the clamping seat and installed inside the clamping seat. The sliding frame slides horizontally along the inner bottom of the clamping seat. A connecting frame is fixedly installed above the rear end of the sliding frame by welding.

[0023] When the above technical solution is adopted, the bottom of the sliding frame is slidably fitted with a chute opened at the inner bottom of the clamping seat. This design enables the sliding frame to slide smoothly and steadily in the horizontal direction, thereby accurately adjusting the lateral position of the driving wheel to adapt to the clamping requirements of bar bodies with different diameters, and improving the flexibility and practicality of the equipment; the connecting frame welded above the rear end of the sliding frame provides a stable support structure for the installation of the driving component.

[0024] Preferably, the driving assembly further includes a driving motor. The driving motor is fixedly installed at the rear end of the sliding frame through bolts and a connecting frame. The output shaft of the driving motor is installed with a driving sprocket through key connection. The driving sprocket meshes with the inner chain teeth of the transmission chain, and the outer chain teeth of the transmission chain mesh with a driven sprocket. One end of the driving wheel passing through the sliding frame is fixedly connected to the center of the driven sprocket through key connection.

[0025] When the above technical solution is adopted, the driving motor is fixedly installed on the connecting frame through bolts, and the installation method is simple and reliable; the output shaft of the driving motor is installed with a driving sprocket through key connection, the driving sprocket meshes with the driven sprocket through the transmission chain, and the driven sprocket and the driving wheel are connected through key connection. This transmission method can stably transmit the power of the driving motor to the driving wheel, ensure the stable rotation of the driving wheel, thereby driving the rod body to rotate stably and improving the cutting efficiency.

[0026] Preferably, the driving wheel is made of stainless steel and its outer wall is coated with a soft rubber layer. Anti-slip particles are provided on the outer wall of the soft rubber layer. The circumferential surface of the driving wheel contacts but is not fixedly connected to the outer wall of the rod body. The driving wheel, the first driven roller and the second driven roller clamp the rod body.

[0027] When the above technical solution is adopted, the driving wheel made of stainless steel ensures that it has sufficient strength and wear resistance, and extends the service life; the soft rubber layer and anti-slip particles coated on the outer wall increase the friction with the rod body. When driving the rod body to rotate, it can better transmit power, prevent the rod body from slipping, and at the same time the soft rubber layer can also avoid damaging the surface of the rod body; the driving wheel, the first driven roller and the second driven roller jointly clamp the rod body, improving the stability and reliability of the clamping.

[0028] Preferably, the robotic arm assembly includes a mounting base. Mounting holes are provided at the bottom of the mounting base. The mounting bolts pass through the mounting holes and are tightly installed in the threaded holes provided on the upper end surface of the bottom plate at the rear end of the chip removal groove.

[0029] When the above technical solution is adopted, the mounting base of the robotic arm assembly is tightly mounted to the bottom plate through mounting bolts, ensuring the firmness of the installation of the robotic arm assembly. A dedicated micro motor is provided on the mounting base. The output shaft of the micro motor is connected to the first rotating arm through a gear transmission device. When the micro motor is started, through the meshing transmission between the gears, the first rotating arm can be accurately controlled to rotate around the mounting base, realizing the angular adjustment of the robotic arm in the horizontal direction. Between the first rotating arm and the second rotating arm, there is also an independent micro motor. The micro motor is connected to the second rotating arm through a belt transmission device. When the micro motor operates, it drives the second rotating arm to rotate relative to the first rotating arm, realizing the angular change of the robotic arm in the vertical direction. This transmission method enables the first rotating arm and the second rotating arm to rotate flexibly in multiple directions, greatly expanding the working range of the cutting head. The telescopic arm can realize the telescopic of the length, further improving the positioning accuracy and flexibility of the cutting head, and facilitating the accurate movement of the cutting head to the position to be cut; the cutting blade and the protective cover installed on the cutting head can effectively protect the safety of the operator while ensuring the cutting function, preventing the danger generated during the cutting process from harming the operator.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] The present invention is provided with a longitudinal adjustment assembly. The bottom of the core component, the adjustment cylinder, is firmly fixed to the outer wall of the clamping seat through bolts. This connection method not only ensures the stability of the adjustment cylinder but also facilitates disassembly and maintenance when necessary. The top telescopic end of the adjustment cylinder is firmly fixed and installed with a top frame by welding. The second driven roller is rotatably installed inside the top frame through a bearing. During the actual operation process, the operator only needs to issue an instruction through the control cabinet according to the diameter of the bar body to be processed, and control the adjustment cylinder to perform telescopic actions. When the adjustment cylinder expands and contracts, it will drive the top frame and the second driven roller to rise or fall together, so as to flexibly adjust the height of the second driven roller, enabling the first driven roller and the second driven roller to closely fit the outer wall of the bar body with different diameters, realizing the stable clamping of bars with different diameters, and perfectly overcoming the problem that the support mechanism with a fixed size can only clamp steel pipes of a single size.

[0032] At the same time, the present invention is also equipped with a lateral adjustment component. The driving motor is firmly fixed and installed at the front end of the clamping seat by bolts, and its output shaft is connected to the lead screw by a coupling. This transmission mode can not only ensure the stable transmission of power, but also has a high transmission accuracy. The rear end of the lead screw is threadedly installed with the threaded hole opened on the sliding frame, and the sliding frame is slidably matched with the slide groove opened at the bottom of the inner side of the clamping seat. When the lateral position of the driving wheel needs to be adjusted, the operator only needs to start the driving motor. After the driving motor is running, it will drive the lead screw to rotate. Due to the threaded transmission relationship between the lead screw and the sliding frame, the rotation of the lead screw will be converted into a linear motion of the sliding frame in the horizontal direction, thereby realizing the precise adjustment of the lateral position of the driving wheel. In this way, the driving wheel can cooperate with the first driven roller and the second driven roller to better adapt to the clamping requirements of bars of different diameters, avoiding the cumbersome operation of frequently replacing the support mechanism due to different bar diameters, and greatly improving work efficiency.

[0033] In addition, the structural design of the present invention abandons the design of limiting the processing length of steel pipes in the prior art. This makes the bar body free of any obstruction in the length direction, and both shorter and longer bars can be smoothly placed between the two clamping components for processing. This design greatly improves the flexibility and adaptability of the device in actual use, can meet the processing requirements of bars of different lengths, effectively solves the limitation problems mentioned in the background technology, significantly improves the overall working efficiency of the device, and brings higher economic and production benefits to industrial production.

Specific implementation mode

[0043] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] Embodiment 1

[0045] As Figures 1 to 8 shown, an embodiment provided by the present invention: a robotic arm cutting machine for manufacturing an industrial automatic control device, including a chassis 1, a robotic arm assembly 2 is fixedly installed on the rear end of the upper end surface of the chassis 1 by mounting bolts, and clamping assemblies 3 are fixedly installed on both sides of the front end of the upper end surface of the chassis 1 by mounting bolts respectively.

[0046] The base 31 includes a clamping seat 311, a reserved hole 313 is opened at the front end of the clamping seat 311, a first driven roller 312 is rotatably installed at the top inside the clamping seat 311 through a bearing, and a chute is opened at the bottom inside the clamping seat 311;

[0047] The longitudinal adjustment assembly 33 includes an adjustment cylinder 331, the bottom of the adjustment cylinder 331 is fixedly connected to the outer wall of the clamping seat 311 by bolts, the telescopic end of the top of the adjustment cylinder 331 is fixedly installed with a top frame 332 by welding, and a second driven roller 333 is rotatably installed inside the top frame 332 through a bearing;

[0048] The lateral adjustment assembly 32 includes a driving motor 321. The driving motor 321 is fixedly installed at the front end of the clamping seat 311 by bolts. The output shaft at the rear end of the driving motor 321 is drivingly installed with a lead screw 322 through a coupling. The rear end of the lead screw 322 is threadedly installed with a threaded hole formed on the sliding frame 323. The sliding frame 323 is slidably fitted with a chute formed at the inner bottom of the clamping seat 311 and installed inside the clamping seat 311;

[0049] The driving assembly 34 includes a driving wheel 345. The driving wheel 345 is rotatably installed at the front end inside the sliding frame 323 through a bearing.

[0050] Specifically, for the longitudinal adjustment assembly 33, the bottom of the core component, the adjustment cylinder 331, is firmly fixedly connected to the outer wall of the clamping seat 311 by bolts. This connection method not only ensures the stability of the adjustment cylinder 331 but also facilitates disassembly and maintenance when necessary. The top telescopic end of the adjustment cylinder 331 is firmly fixedly installed with a top frame 332 by welding. The second driven roller 333 is rotatably installed inside the top frame 332 through a bearing. During actual operation, the operator only needs to issue an instruction through the control cabinet 16 according to the diameter of the bar body 4 to be processed, and control the adjustment cylinder 331 to perform telescopic actions. When the adjustment cylinder 331 expands and contracts, it will drive the top frame 332 and the second driven roller 333 to rise or fall together, so as to flexibly adjust the height of the second driven roller 333, enabling the first driven roller 312 and the second driven roller 333 to closely fit the outer wall of the bar body 4 with different diameters, realizing stable clamping of bars with different diameters, and perfectly overcoming the problem that the support mechanism has a fixed size and can only clamp steel pipes of a single size.

[0051] At the same time, the present invention is also equipped with a lateral adjustment assembly 32. The driving motor 321 is firmly fixedly installed at the front end of the clamping seat 311 by bolts, and its output shaft is drivingly connected to the lead screw 322 through a coupling.

When it is necessary to adjust the lateral position of the driving wheel 345, the operator only needs to start the driving motor 321. After the driving motor 321 operates, it will drive the lead screw 322 to rotate. Due to the threaded transmission relationship between the lead screw 322 and the sliding frame 323, the rotation of the lead screw 322 will be converted into a linear motion of the sliding frame 323 in the horizontal direction, thereby realizing precise adjustment of the lateral position of the driving wheel 345. In this way, the driving wheel 345 can cooperate with the first driven roller 312 and the second driven roller 333 to better adapt to the clamping requirements of bars with different diameters, avoiding the cumbersome operation of frequently replacing the support mechanism due to different bar diameters, and greatly improving work efficiency.

This enables the bar body 4 to have no obstruction in the length direction. Whether it is a shorter bar or a longer bar, it can be smoothly placed between the two clamping components 3 for processing. This design greatly improves the flexibility and adaptability of the device in actual use, can meet the processing requirements of bars of different lengths, effectively solves the limitations mentioned in the background art, significantly improves the overall working efficiency of the device, and brings higher economic benefits and production benefits to industrial production.

[0053] Embodiment 2

[0054] In order to make the device operate conveniently, safely and efficiently, as Figure 2 shown, in this embodiment, the chassis 1 includes a bottom plate 11. Threaded holes are respectively opened at the four corners of the lower end surface of the bottom plate 11. The balance foot pads 14 are installed on the bottom plate 11 by being threadedly matched with the threaded holes. The front end of the upper end surface of the bottom plate 11 is fixedly installed with a baffle 13 by welding. The baffle 13 is designed with an arc-shaped structure and bends backward. A chip removal groove 12 is opened in the middle of the front end of the upper end surface of the bottom plate 11. The chip removal groove 12 is located at the rear end of the baffle 13. A control cabinet 16 is fixedly installed at a corner of the rear end of the upper end surface of the bottom plate 11 by bolts.

[0055] Specifically, the threaded holes at the four corners of the lower end surface of the bottom plate 11 are threadedly matched with the balance foot pads 14, which can effectively adjust the levelness of the equipment, ensure that the equipment can be stably placed in different ground environments, and provide a stable basis for subsequent cutting operations; the baffle 13 is designed with an arc-shaped structure and bends backward, which can effectively block the flying of chips generated during cutting, avoid the harm to operators caused by chips and the pollution to the surrounding environment; the chip removal groove 12 is located at the rear end of the baffle 13, which is convenient for centralized collection of chips generated by cutting and is convenient for cleaning and maintenance; the control cabinet 16 is fixedly installed at a corner of the rear end of the upper end surface of the bottom plate 11 by bolts, which is convenient for operating and controlling the operation of the equipment and improves the overall operability of the equipment.

[0056] Furthermore, a support frame 15 is fixedly installed at the bottom of the control cabinet 16 by welding. An installation hole is opened at the bottom of the support frame 15. The installation bolt passes through the installation hole and is tightly connected with the corresponding threaded hole on the bottom plate 11. A touch screen 162 and control buttons 161 are provided on the front of the control cabinet 16 by inlaying. A programmable logic controller is installed inside the control cabinet 16. The control cabinet 16 is electrically connected to the robotic arm assembly 2 and the clamping assembly 3 through wires.

[0057] Specifically, the bottom of the control cabinet 16 is fixedly installed on the support frame 15 by welding. The support frame 15 is then tightly connected to the bottom plate 11 through installation bolts, making the installation of the control cabinet 16 more stable and reliable. The touch screen 162 and the control buttons 161 are arranged on the front of the control cabinet 16, facilitating the operator's human-machine interaction and enabling intuitive parameter setting and operation control of the equipment. The control cabinet 16 is internally equipped with an editable logic controller, which can perform precise logic control on the robotic arm assembly 2 and the clamping assembly 3, realizing automated cutting operations and improving production efficiency and cutting accuracy.

[0058] Embodiment III

[0059] To make the clamping assembly stable and flexible, as Figures 4 to 8 shown, in this embodiment, the number of clamping assemblies 3 is two. Installation holes are respectively opened at the bottoms of the bases 31 of the two clamping assemblies 3, and they are tightly installed through the installation bolts passing through the installation holes and the threaded holes opened on the upper end surfaces of the bottom plate 11 on both sides of the chip removal groove 12. A bar stock body 4 is clamped by the two clamping assemblies 3 directly above the chip removal groove 12.

[0060] Specifically, the two clamping assemblies 3 are respectively tightly installed on the bottom plate 11 on both sides of the chip removal groove 12 through installation bolts. The installation method is simple and firm, and can stably support and fix the clamping assembly 3. A bar stock body 4 is clamped by the two clamping assemblies 3 directly above the chip removal groove 12. This layout enables the chips generated during the cutting process to directly fall into the chip removal groove 12, avoiding chip accumulation in the working area and affecting the cutting operation. At the same time, it is also convenient for centralized chip cleaning to ensure a clean working environment.

[0061] Furthermore, the first driven roller 312 and the second driven roller 333 are located on the same vertical line. The first driven roller 312 and the second driven roller 333 are of matching sizes and are both designed with stainless steel materials. The circumferential surfaces of the first driven roller 312 and the second driven roller 333 are in contact with the outer wall of the bar stock body 4 but not fixedly connected. Anti-slip patterns parallel to the bar stock body 4 are provided on the outer walls of the first driven roller 312 and the second driven roller 333. The first driven roller 312 is located directly below the second driven roller 333.

[0062] Specifically, the first driven roller 312 and the second driven roller 333 are located on the same vertical line and are of matching sizes, which can evenly clamp the bar stock body 4 and prevent the bar stock body 4 from shifting during the cutting process due to uneven stress. The driven rollers designed with stainless steel materials have good wear resistance and corrosion resistance, which can extend their service life. The circumferential surfaces of the driven rollers are in contact with the outer wall of the bar stock body 4 but not fixedly connected, which can effectively clamp the bar stock body 4 without affecting its rotation. The anti-slip patterns provided on the outer walls increase the friction with the bar stock body 4, improving the clamping stability and preventing the bar stock body 4 from slipping during the cutting process.

[0063] Further, the number of adjusting cylinders 331 is two. The two adjusting cylinders 331 are respectively fixedly installed on both sides of the clamping seat 311 by bolts. The top telescopic ends of the two adjusting cylinders 331 are respectively fixedly connected to both sides of the top frame 332 by welding. The top frame 332 is fixedly installed on the opposite side of the two adjusting cylinders 331.

[0064] Specifically, the two adjusting cylinders 331 are respectively fixedly installed on both sides of the clamping seat 311 and the top telescopic ends are fixedly connected to both sides of the top frame 332 by welding, so that the top frame 332 is evenly stressed during the lifting process and can stably adjust the height of the second driven roller 333, thereby better adapting to the clamping requirements of the bar body 4 with different diameters and improving the versatility and adaptability of the equipment.

[0065] Further, the bottom of the sliding frame 323 is slidably fitted with a chute opened at the inner bottom of the clamping seat 311 and installed inside the clamping seat 311. The sliding frame 323 slides horizontally along the inner bottom of the clamping seat 311. A connecting frame 324 is fixedly installed above the rear end of the sliding frame 323 by welding.

[0066] Specifically, the bottom of the sliding frame 323 is slidably fitted with a chute opened at the inner bottom of the clamping seat 311. This design enables the sliding frame 323 to slide smoothly and steadily in the horizontal direction, thereby precisely adjusting the lateral position of the driving wheel 345 to adapt to the clamping requirements of the bar body 4 with different diameters and improving the flexibility and practicality of the equipment; the connecting frame 324 welded above the rear end of the sliding frame 323 provides a stable support structure for the installation of the driving component 34.

[0067] Further, the driving component 34 further includes a driving motor 341. The driving motor 341 is fixedly installed on the rear end of the sliding frame 323 by bolts with the connecting frame 324. The output shaft of the driving motor 341 is installed with a driving sprocket 342 through key connection. The driving sprocket 342 meshes with the inner chain teeth of the transmission chain 343. The outer chain teeth of the transmission chain 343 mesh with a driven sprocket 344. One end of the driving wheel 345 passing through the sliding frame 323 is fixedly connected to the center of the driven sprocket 344 through key connection.

[0068] Specifically, the driving motor 341 is fixedly installed on the connecting frame 324 by bolts, and the installation method is simple and reliable; the output shaft of the driving motor 341 is installed with the driving sprocket 342 through key connection. The driving sprocket 342 meshes with the driven sprocket 344 through the transmission chain 343. The driven sprocket 344 and the driving wheel 345 are connected through key connection. This transmission method can stably transmit the power of the driving motor 341 to the driving wheel 345, ensure the stable rotation of the driving wheel 345, and thus drive the bar body 4 to rotate stably, improving the cutting efficiency.

[0069] Furthermore, the driving wheel 345 is made of stainless steel and its outer wall is coated with a soft rubber layer. Anti-slip particles are provided on the outer wall of the soft rubber layer. The circumferential surface of the driving wheel 345 contacts but is not fixedly connected to the outer wall of the bar body 4. The driving wheel 345, the first driven roller 312 and the second driven roller 333 clamp the bar body 4.

[0070] Specifically, the driving wheel 345 made of stainless steel ensures its sufficient strength and wear resistance, extending its service life; the soft rubber layer coated on the outer wall and the anti-slip particles increase the friction force between the driving wheel 345 and the bar body 4. When driving the bar body 4 to rotate, the power can be better transmitted, preventing the bar body 4 from slipping. At the same time, the soft rubber layer can also avoid damaging the surface of the bar body 4; the driving wheel 345, the first driven roller 312 and the second driven roller 333 jointly clamp the bar body 4, improving the stability and reliability of the clamping.

[0071] Embodiment 4

[0072] In order to make the robotic arm firmly installed, rotate flexibly and cut safely and efficiently, as Figure 3 shown, in this embodiment, the robotic arm assembly 2 includes a mounting base 21. A mounting hole is opened at the bottom of the mounting base 21. The mounting bolt passes through the mounting hole and is tightly installed with the threaded hole opened on the upper end surface of the bottom plate 11 at the rear end of the chip removal groove 12. A first-level rotating arm 22 is rotatably installed on the mounting base 21 through a bearing. A second-level rotating arm 23 is rotatably installed on the first-level rotating arm 22 through a bearing. A telescopic arm 24 is fixedly installed on the second-level rotating arm 23 through a bolt. The telescopic end of the telescopic arm 24 is fixedly installed with a cutting head 25 by welding. A cutting blade and a protective cover are installed on the cutting head 25 through bolts.

[0073] Specifically, the mounting base 21 of the robotic arm assembly 2 is tightly mounted to the bottom plate 11 through mounting bolts, ensuring the firmness of the installation of the robotic arm assembly 2. A dedicated micro-motor is provided on the mounting base 21. The output shaft of this micro-motor is connected to the first rotating arm 22 through a gear transmission device. When the micro-motor is started, through the meshing transmission between the gears, it can accurately control the first rotating arm 22 to rotate around the mounting base 21, realizing the angular adjustment of the robotic arm in the horizontal direction. Between the first rotating arm 22 and the second rotating arm 23, there is also an independent micro-motor. This micro-motor is connected to the second rotating arm 23 through a belt transmission device. When the micro-motor operates, it drives the second rotating arm 23 to rotate relative to the first rotating arm 22, realizing the angular change of the robotic arm in the vertical direction. This transmission method enables the first rotating arm 22 and the second rotating arm 23 to rotate flexibly in multiple directions, greatly expanding the working range of the cutting head 25. The telescopic arm 24 can realize the telescopic of its length, further improving the positioning accuracy and flexibility of the cutting head 25, and facilitating the accurate movement of the cutting head 25 to the position to be cut; the cutting blade and the protective cover installed on the cutting head 25 can effectively protect the safety of the operator while ensuring the cutting function, preventing the danger generated during the cutting process from harming the operator.

[0074] When the present invention is in use:

[0075] Longitudinal adjustment: According to the diameter of the bar body 4 to be cut, the control cabinet 16 is used to control the adjustment cylinder 331 to work. Since the number of adjustment cylinders 331 is two, they are respectively fixedly installed on both sides of the clamping seat 311, and the top telescopic ends of them are welded and fixed to both sides of the top frame 332. By controlling the telescopic of the adjustment cylinder 331, the top frame 332 is raised or lowered, thereby adjusting the height of the second driven roller 333 to ensure that the first driven roller 312 and the second driven roller 333 can be in good contact with the outer wall of the bar body 4, and the first driven roller 312 is located directly below the second driven roller 333. The circumferential surfaces of both of them are in contact with the outer wall of the bar body 4 but are not fixedly connected. At the same time, the anti-slip patterns on their outer walls play a preliminary role in longitudinal positioning and anti-slip of the bar body 4.

[0076] Transverse adjustment: Start the drive motor 321. The drive motor 321 is fixedly installed at the front end of the clamping seat 311 through bolts. Its output shaft is installed with a lead screw 322 through a coupling drive. The lead screw 322 is threadedly installed with the threaded hole opened on the sliding frame 323. When the drive motor 321 works, the lead screw 322 rotates, driving the sliding frame 323 to slide horizontally along the chute opened at the inner bottom of the clamping seat 311, thereby adjusting the transverse position of the driving wheel 345, so that the driving wheel 345 can adapt to the clamping requirements of the bar body 4 with different diameters with the first driven roller 312 and the second driven roller 333.

[0077] Place the bar to be cut: Place the bar body 4 between the two clamping assemblies 3 so that the bar body 4 is located directly above the chip removal groove 12. Through the adjusted clamping assembly 3, the first driven roller 312, the second driven roller 333 and the driving wheel 345 clamp the bar body 4. The driving wheel 345 is made of stainless steel and its outer wall is covered with a soft rubber layer. The outer wall of the soft rubber layer is provided with anti-skid particles. Its circumferential surface contacts the outer wall of the bar body 4 but is not fixedly connected. It cooperates with the first driven roller 312 and the second driven roller 333 to achieve stable clamping of the bar body 4.

[0078] Robot arm positioning: The action of the robot arm assembly 2 is controlled by the control cabinet 16. The mounting seat 21 of the robot arm assembly 2 is tightly mounted with the threaded hole opened on the upper end surface of the bottom plate 11 at the rear end of the chip groove 12 through the mounting bolts. The primary rotating arm 22 on the mounting seat 21 rotates through the bearing, and the secondary rotating arm 23 on the primary rotating arm 22 also rotates through the bearing. The telescopic arm 24 is fixedly mounted on the secondary rotating arm 23. By controlling the rotation of the primary rotating arm 22 and the secondary rotating arm 23 and the extension and retraction of the telescopic arm 24, the cutting machine head 25 is moved to the position to be cut. The cutting machine head 25 is equipped with a cutting blade and a protective cover.

[0079] Cutting operation: After completing the above steps and ensuring that the bar body 4 is firmly clamped and the mechanical arm assembly 2 is accurately positioned, start the cutting blade of the cutting machine head 25. At the same time, start the driving motor 341 of the driving assembly 34 through the control cabinet 16. The driving motor 341 is fixedly installed on the connecting frame 324, and its output shaft is connected to the driving sprocket 342 through a key connection. The driving sprocket 342 is meshed with the inner sprocket teeth of the transmission chain 343, and the outer sprocket teeth of the transmission chain 343 are meshed with the driven sprocket 344. The center of the driven sprocket 344 is fixedly connected to one end of the driving wheel 345 passing through the sliding frame 323 through a key connection. After the driving motor 341 is running, it drives the driving sprocket 342 to rotate, and the driven sprocket 344 and the driving wheel 345 rotate accordingly through the transmission chain 343. Since the circumferential surface of the driving wheel 345 contacts the outer wall of the rod body 4 and its outer wall has anti-skid particles, the rotation of the driving wheel 345 will drive the rod body 4 to rotate synchronously. During the process of the cutting blade cutting the rod body 4, the rotation of the rod body 4 can accelerate the cutting process and improve the cutting efficiency. The debris generated during the cutting process will be discharged through the chip discharge groove 12. The baffle 13 adopts an arc structure design and is bent backwards to prevent the debris from splashing.

[0080] Post-cutting processing: After cutting is completed, turn off the cutting blade of the cutting machine head 25. Control the clamping assembly 3 to release the clamping of the bar body 4 through the control cabinet 16, and remove the cut bar. Clean the debris in the chip removal groove 12, turn off the power of the equipment, and complete the entire cutting operation process.
