Description
Technical Field
[0001] This invention relates to the field of cutting technology, and in particular to a fastening and positioning device for a metal strip cutting machine. Background Technology
[0002] Metal strip, also known as strip steel or steel strip, is a long strip of metal with a relatively large width and thin thickness. It is one of the basic raw materials in the fields of metallurgy and machinery manufacturing. In actual processing, it is often necessary to unroll the rolled metal strip and cut it to the required length to obtain the sheet blanks required for subsequent processes. This process requires the use of a cutting machine to cut it.
[0003] In existing metal strip cutting processes, to ensure that the workpiece does not shift during cutting, a vertical clamping method from top to bottom is generally used to fix the metal strip. However, in operation, the clamping components of this top-mounted clamping structure directly cover the space above the metal strip, which objectively creates a physical obstruction. This not only limits the operator's line of sight but also seriously interferes with the workpiece's pick-up and drop path. Therefore, this application proposes a clamping and positioning device for a metal strip cutting machine. Summary of the Invention
[0004] The purpose of this invention is to address the problem in the prior art where the clamping structure obstructs the top of the workpiece, and to propose a clamping and positioning device for a metal strip cutting machine.

The lifting mechanism, connected to the drive component, is used to lift the workpiece when the drive component controls the execution component to reset.
[0006] Optionally, the drive assembly includes a hydraulic cylinder and a top plate. The hydraulic cylinder is installed inside the processing table, the top plate is connected to the output end of the hydraulic cylinder, and the top end of the top plate is connected to the actuation assembly.
[0007] Optionally, the execution component includes two sets of concave plates, a transmission plate, a guide groove, and a guide rod. Both sets of concave plates are fixed to the top of the top plate. The transmission plate is rotatably connected to the interior of the two sets of concave plates. The end of the transmission plate away from the concave plates is located on the outer side of the clamping plate. The guide groove is opened inside the two sets of transmission plates. The guide rod is fixed to the top of the inner wall of the processing table and is slidably connected to the interior of the guide groove.
[0008] Optionally, the guide groove includes a straight groove and an inclined groove.
[0009] Optionally, the lifting mechanism includes a top rod, a top hole, and a nut. The top hole is located inside the conveyor table, and the top rod is mounted to the top of the top plate via the nut.
[0010] Optionally, the processing table is equipped with a dust removal mechanism inside, which is used to transmit air to the inside of the clamping plate so that the air is blown toward the workpiece clamping area.
[0011] Optionally, the dust removal mechanism includes a blower, an air supply pipe, an air collection pipe, two sets of air distribution pipes, and multiple sets of small holes. The blower is installed inside the processing table, the air supply pipe is connected to the output end of the blower, the air collection pipe is fixed inside the processing table, the end of the air supply pipe away from the blower is fixed inside the air collection pipe, both sets of air distribution pipes are fixed inside the air collection pipe, the ends of the two sets of air distribution pipes away from the air collection pipe are respectively fixed to the top of the clamping plate, and the multiple sets of small holes are all opened at the bottom of the clamping plate.
[0012] Optionally, the inside of the gas collecting pipe is provided with a ventilation opening, and a gas supply pipe is fixedly connected inside the ventilation opening. The end of the gas supply pipe away from the gas collecting pipe is fixedly connected to the inside of the top rod, and a ventilation groove is provided at the top of the top rod.
[0013] Optionally, a side rod is fixedly connected to the outer side of the top plate, and a baffle is fixedly connected to the end of the side rod away from the top plate. The baffle is slidably connected to the inside of the gas collecting pipe.
[0014] Optionally, the outer side of the clamping disc is provided with a threaded groove, and a nut is threadedly connected to the outer side of the threaded groove.
[0015] Compared with the prior art, this application includes at least one of the following beneficial technical effects: This invention provides power through a drive component, which controls the execution component to move the symmetrically distributed clamping discs downward, applying stable pressure to the workpiece and achieving precise clamping and positioning, effectively ensuring cutting accuracy. After cutting, the drive component can drive the execution component to reset and further drive the clamping discs to swing and move away, making room above the workpiece, thereby greatly facilitating the picking and placing of the workpiece and improving the smoothness and safety of the operation.
[0016] Furthermore, by linking the lifting mechanism with the drive components, the workpiece is automatically lifted after cutting, creating a gap between it and the conveyor table. This design allows workers to easily insert their fingers to pick up the workpiece, completely avoiding the difficulty of picking up the workpiece caused by it being too tightly attached to the table surface, and significantly improving the ease of operation and work efficiency.

[0019] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.
[0020] like Figure 1 and Figure 2As shown, the present invention proposes a fastening and positioning device for a metal strip cutting machine, including a processing table 1, a control console 2 installed at the top of the processing table 1, the processing table 1 providing a support point for the installation of the control console 2, a conveyor for conveying workpieces inside the control console 2, a conveyor table 3 and a robot arm 4 fixedly connected to the top of the processing table 1, the conveyor can transport rolled workpieces (in this embodiment, referring to metal strips) to the surface of the conveyor table 3 for flattening, the output end of the robot arm 4 is equipped with a laser cutter 5, the robot arm 4 can control the lateral position of the laser cutter 5, and the laser cutter 5 can cut the workpieces flattened on the surface of the conveyor table 3. It should be noted that the conveyor, robot arm 4 and laser cutter 5 are all conventional technologies in existing metal strip cutting technology, and the technology is mature, so they will not be elaborated on further.
[0021] As one implementation method, such as Figure 1 - Figure 4 As shown, the clamping and positioning device also includes at least two sets of clamping discs 6 for fixing workpieces and a fixing mechanism. The two sets of clamping discs 6 are symmetrically distributed at the top of the conveyor table 3. When the two sets of clamping discs 6 apply pressure to the workpiece on the surface of the conveyor table 3, they can clamp and position it. The fixing mechanism includes a drive component and an execution component, wherein: the drive component is used to provide a power source for the execution component. When it is necessary to clamp and position the workpiece, the drive component first controls the execution component to run. In the initial state, the two sets of clamping discs 6 are above the workpiece. The execution component is used to control the direction of the clamping discs 6, so that the clamping discs 6 move down to squeeze and fix the workpiece. When the drive component is running, the execution component will drive the two sets of clamping plates 6 to move downward. When the two sets of clamping plates 6 contact the workpiece, they will apply downward pressure to the workpiece. In conjunction with the conveyor table 3, the workpiece can be fixed in place. After the workpiece is cut by the laser cutter 5, the drive component will drive the execution component to reset. At this time, the execution component will drive the two sets of clamping plates 6 to reset synchronously. After the two sets of clamping plates 6 are reset to their initial positions, the drive component will continue to control the execution component to run. The execution component will continue to drive the two sets of clamping plates 6 to move. At this time, the execution component will drive the two sets of clamping plates 6 to swing, thereby detaching them from the top of the workpiece, which will facilitate the pick-up and drop operations of the workers.
[0022] Furthermore, such as Figure 3 and Figure 4 As shown, the fastening and positioning device also includes a lifting mechanism. The lifting mechanism is connected to the drive component, and when the drive component controls the execution component to reset, the lifting mechanism will lift the cut workpiece, so that there is a certain gap between the workpiece and the conveyor table 3, which makes it easy for the operator to put their fingers into the gap to pick up the workpiece, and avoids the situation where the workpiece is stuck to the top of the conveyor table 3, making it inconvenient to exert force.
[0023] Furthermore, such as Figure 2 , Figure 3and Figure 4 As shown, the drive assembly includes a hydraulic cylinder 7 and a top plate 8. The drive assembly is described in detail below: The hydraulic cylinder 7 is installed inside the processing table 1. The top plate 8 is connected to the output end of the hydraulic cylinder 7. When the hydraulic cylinder 7 is running, its output end will drive the top plate 8 to run. The top of the top plate 8 is connected to the execution component. When the top plate 8 moves down, it will apply power to the execution component and control the execution component to run, so that the execution component drives the two sets of clamping plates 6 to move down and apply pressure to the workpiece.
[0024] As one implementation method, such as Figure 2 , Figure 3 and Figure 4 As shown, the actuation component includes two sets of concave plates 9, a transmission plate 10, a guide groove 11, and a guide rod 12. The actuation component is described in detail below: Both sets of concave plates 9 are fixed to the top of the top plate 8. When the top plate 8 moves, it drives the two sets of concave plates 9 to move synchronously. The transmission plates 10 are rotatably connected to the inside of the two sets of concave plates 9. In the first state, when the concave plate 9 moves downward, it pulls the transmission plate 10 to move downward synchronously. The end of the transmission plate 10 away from the concave plate 9 is located on the outside of the clamping plate 6. The guide grooves 11 are respectively opened inside the two sets of transmission plates 10. The guide rod 12 is fixed to the top of the inner wall of the processing table 1, and the guide rod 12 is slidably connected to the inside of the guide groove 11. The guide groove 11 includes a straight groove and an oblique groove. Since the guide rod 12 is initially inside the straight groove, the guide rod 12 and the straight groove guide each other. In the first state, the downward movement of the transmission plate 10 causes the clamping plate 6 to move vertically downward, creating downward pressure on the workpiece and forcing it to fix the workpiece in place. After the workpiece is processed, the hydraulic cylinder 7 moves the top plate 8 upward to reset, and the upward movement of the top plate 8, in turn, causes the transmission plate 10 to move upward to reset via the concave plate 9. At this point, the clamping plate 6 will disengage from the workpiece. In the second state, as the top plate 8 continues to move upward, the inclined groove inside the transmission plate 10 will contact the guide rod 12, and the inclined groove will be continuously squeezed by the guide rod 12, causing the transmission plate 10 to swing. The swing of the transmission plate 10 will cause the clamping plate 6 to swing, disengaging it from the workpiece and making it easier for the operator to pick up the workpiece.
[0025] Furthermore, such as Figure 3 and Figure 4 As shown, the lifting mechanism includes a top rod 13, a top hole 14, and a nut 15. The lifting mechanism is described in detail below: The top hole 14 is located inside the conveyor table 3. The diameter of the top hole 14 is matched with the diameter of the top end of the top rod 13. The top rod 13 is installed on the top end of the top plate 8 by a nut 15. As a prior art technology, the nut 15 can quickly connect the top rod 13 to the top plate 8. In the initial state, there is a certain distance between the top rod 13 and the top hole 14. When the transmission plate 10 swings, that is, when the workpiece needs to be removed, the top plate 8 is in an upward state. The rise of the top plate 8 will drive the top rod 13 to rise. The rise of the top rod 13 will pass over the top hole 14 and contact the workpiece. As the nut 15 continues to move upward, the nut 15 will apply an upward pushing force to the cut workpiece, thereby forcing a certain gap between the workpiece and the conveyor table 3, which makes it easy for the operator to place their fingers in the gap to pick up the workpiece.
[0026] Furthermore, such as Figure 5 and Figure 6 As shown, the processing table 1 is equipped with a dust removal mechanism inside. The processing table 1 supports the dust removal mechanism. The dust removal mechanism is used to transmit air to the inside of the clamping plate 6, so that the air is blown towards the workpiece clamping area. When the dust removal mechanism is working, it can transmit the external wind force to the inside of the clamping plate 6 and blow it from the bottom of the clamping plate 6 towards the workpiece clamping area, blowing away the dust and impurities in that area. This avoids the problem of dust and impurities causing scratches or affecting clamping when the clamping plate 6 contacts the workpiece.
[0027] As one implementation method, such as Figure 5 and Figure 6 As shown, the dust removal mechanism includes a blower 16, an air supply pipe 17, an air collection pipe 18, two sets of air supply pipes 19, and multiple sets of small holes 20. The dust removal mechanism is described in detail below: The blower 16 is installed inside the processing table 1. The air supply pipe 17 is connected to the output end of the blower 16. As prior art, the blower 16, during operation, transmits external air to the interior of the air supply pipe 17. The air collecting pipe 18 is fixedly connected inside the processing table 1. The end of the air supply pipe 17 away from the blower 16 is fixedly connected to the interior of the air collecting pipe 18. The airflow is then transmitted to the interior of the air collecting pipe 18. Both sets of air distribution pipes 19 are fixed inside the air collecting pipe 18, which in turn distributes the airflow to the interiors of the two sets of air distribution pipes 19. The ends of the two sets of air distribution pipes 19 furthest from the air collecting pipe 18 are fixed to the top of the clamping plate 6. The air distribution pipes 19 then blow the air into the interior of the clamping plate 6. Multiple sets of small holes 20 are opened at the bottom of the clamping plate 6. Finally, the air inside the clamping plate 6 is blown through the multiple sets of small holes 20 to the workpiece clamping area, thereby achieving the function of dust removal.
[0028] Furthermore, such as Figure 3 and Figure 7As shown, the air collecting pipe 18 has a ventilation opening inside, and an air supply pipe 21 is fixedly connected inside the ventilation opening. When the air collecting pipe 18 receives air force from the blower 16, it will also transmit part of the air force to the inside of the air supply pipe 21 through the ventilation opening. The end of the air supply pipe 21 away from the air collecting pipe 18 is fixedly connected to the inside of the top rod 13, and the air is transmitted to the inside of the top rod 13 through the air supply pipe 21. The top of the top rod 13 has a ventilation groove 22, and the air is finally blown towards the bottom of the workpiece through the ventilation groove 22 to clean the dust in the area where the workpiece contacts the top rod 13.
[0029] Furthermore, such as Figure 3 and Figure 7 As shown, a side rod 23 is fixedly connected to the outer side of the top plate 8. A baffle 24 is fixedly connected to the end of the side rod 23 away from the top plate 8. In the initial state, the baffle 24 blocks the vent. At this time, the air collecting pipe 18 cannot transmit the air force to the inside of the air supply pipe 21 through the vent, thus avoiding the air force from blowing onto the surface of the workpiece through the ventilation groove 22, which would cause the workpiece to shake when it is to be fixed. The baffle 24 is slidably connected to the inside of the air collecting pipe 18. When the top plate 8 moves upward, that is, when the workpiece is cut and needs to be removed and the workpiece does not need to be fixed, the upward movement of the top plate 8 will drive the side rod 23 to move upward synchronously. The upward movement of the side rod 23 will move the baffle 24 upward, thereby exposing the vent. At this time, the air force inside the air collecting pipe 18 will be transmitted to the inside of the air supply pipe 21 through the vent, so that the air force is finally blown to the bottom of the workpiece through the ventilation groove 22 to perform dust removal and cleaning operations at the contact position of the top rod 13.
[0030] In addition, such as Figure 4 and Figure 6 As shown, the outer side of the clamping disk 6 is provided with a threaded groove 25, and a second nut 26 is threadedly connected to the outer side of the threaded groove 25. The cooperation between the threaded groove 25 and the second nut 26 allows the second nut 26 to quickly fix the clamping disk 6 and the transmission plate 10 together, which facilitates the disassembly and cleaning of the clamping disk 6.
[0031] In this embodiment, firstly, the conveyor transports the workpiece to the surface of the conveyor table 3 and flattens it. When fixing is required, the hydraulic cylinder 7 drives the top plate 8 to move downward, which in turn drives the transmission plate 10 to move downward through the concave plate 9. Under the guidance of the guide rod 12 and the straight groove of the guide groove 11, the clamping plate 6 moves vertically downward to squeeze the workpiece and achieve tight fixing. Then, the robot arm 4 controls the laser cutter 5 to cut. After the cutting is completed, the hydraulic cylinder 7 drives the top plate 8 to move upward and reset, so that the clamping plate 6 is released from the workpiece. As the top plate 8 continues to move upward, the guide rod 12 and the inclined groove of the guide groove 11 cause the transmission plate 10 to move downward. The movable plate 10 swings, causing the clamping plate 6 to swing away from the workpiece. At the same time, the top plate 8 moves upward and lifts the workpiece through the top rod 13 and the top hole 14 to create a gap for easy handling. In addition, the dust removal mechanism operates before clamping: the blower 16 blows air into the clamping plate 6 through the air supply pipe 17, the air collection pipe 18 and the air distribution pipe 19, and blows it through the small hole 20 to the workpiece clamping area for dust removal. When the top plate 8 moves upward, the side rod 23 drives the baffle 24 to move upward to expose the ventilation port of the air collection pipe 18, so that some of the air force is blown to the bottom of the workpiece through the air supply pipe 21 and the ventilation slot 22 to clean the dust.
[0032] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
