Description

Technical Field

[0001] This invention belongs to the field of shipbuilding technology, specifically relating to a cutting auxiliary device and its usage method. Background Technology

[0002] Hull parts are the basic units for hull assembly, and their design and manufacturing quality directly affect the overall performance and construction quality of the ship. To ensure welding quality, many parts require beveling, an indispensable step in the welding process. Beveling methods can be categorized into automatic and semi-automatic cutting based on their level of automation. Automatic cutting is mainly achieved through multi-axis plasma cutting machines, laser cutting machines, or milling machines. These devices offer high levels of automation and machining accuracy, effectively improving production efficiency and processing quality. However, automatic cutting equipment is typically expensive and requires highly skilled operators, and may have limitations in processing certain complex-shaped parts. Semi-automatic cutting, on the other hand, is mainly achieved through semi-automatic cutting machines. These machines are relatively inexpensive, easy to operate, highly flexible, and can adapt to the processing needs of parts with various shapes and sizes.

[0003] In actual production, because simultaneously processing beveling during cutting operations significantly reduces cutting speed and greatly impacts consumable lifespan, and milling machines have relatively low processing efficiency and economy, semi-automatic cutting, as a mature and flexible beveling method, is often used as a supplement to automated beveling equipment. However, in the traditional operating mode, one person is responsible for only one semi-automatic cutting machine, which results in low operating efficiency and is difficult to meet the high-efficiency production requirements of modern shipbuilding. Summary of the Invention

[0004] In view of the problems existing in the prior art described above, this application provides a cutting auxiliary device and its usage method, which can realize precise control of semi-automatic cutting operations and improve work efficiency.

Adjust the height of the support platform of the support component by using the lifting rod of the support component until the height of the support platform is lower than the height of the cutting platform; When the cutting assembly is started, and it moves to the position of the limit block on the support platform, the limit switch of the cutting assembly is triggered by the limit block and sends a stop signal to the control box of the cutting assembly. The control box controls the cutting assembly to stop working according to the stop signal.

[0013] Optionally, the height difference between the support platform and the cutting platform is between 1 mm and 10 mm.

[0014] Optionally, when the cutting assembly travels to the position of the limit block on the support platform, the limit switch of the cutting assembly is triggered and sends a stop signal to the control box of the cutting assembly. The control box controls the cutting assembly to stop moving according to the stop signal, including: The solenoid valve of the cutting assembly is controlled to cut off the supply of cutting gas, thereby stopping the cutting assembly from cutting. The alarm on the cutting assembly is activated to alert the operator that the cutting operation is complete.

[0022] 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.

[0023] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of the present invention. Although the illustrations only show components related to the present invention and are not drawn according to the actual number, shape and size of the components, the shape, quantity, positional relationship and proportion of each component can be arbitrarily changed under the premise of realizing the technical solution of this invention, and the layout of the components may also be more complex.

[0024] Example 1

[0025] Reference Figures 1 to 3 This embodiment provides a cutting auxiliary device, including a cutting assembly 1 and a support assembly 2. The cutting assembly 1 includes a cutting carriage 11, a solenoid valve 12, an alarm 13, a control box 14, and a limit switch 15.

[0026] Reference Figure 3The cutting carriage 11 is the core component of the entire cutting assembly, used to carry the cutting tools and perform the cutting operation. The cutting carriage 11 is mobile, able to move along a predetermined trajectory on the cutting platform to complete the cutting of the steel plate. Its structural design considers stability and flexibility, maintaining smooth operation during the cutting process while facilitating adjustments and maintenance by operators. The control box 14 is the control core of the cutting assembly 1, installed on and communicatively connected to the cutting carriage 11. The solenoid valve 12, alarm 13, and limit switch 15 are all located on the cutting carriage 11 and communicatively connected to the control box 14. Through its communicative connection with the solenoid valve 12, alarm 13, and limit switch 15, the control box 14 achieves comprehensive control of the cutting operation. The control box 14 integrates a microprocessor and related circuits, capable of real-time monitoring of the operating status of the cutting carriage 11 and automatically controlling the start, stop, and alarm functions of the cutting operation based on preset programs and sensor feedback signals. In addition, the control box 14 also has a human-machine interface, through which operators can set parameters, diagnose faults, and perform manual operations. The solenoid valve 12 is used to control the flow of cutting gas (such as propane, oxygen, etc.). The solenoid valve 12 receives signals from the control box 14. When the control box 14 issues a stop signal, the solenoid valve 12 quickly cuts off the gas supply, stopping the cutting carriage 11 from cutting. This design effectively avoids safety accidents caused by gas leaks or accidental cutting, while improving the safety and reliability of the cutting operation. The alarm 13 is used to issue audible and visual alarm signals during the cutting operation. The limit switch 15 is used to detect the position of the cutting carriage 11. When the cutting carriage 11 reaches the preset cutting endpoint, it triggers the control box 14 to issue a stop signal, stopping the cutting carriage 11. The limit switch 15 ensures that the cutting carriage 11 operates strictly according to the preset path and position during the cutting process, avoiding cutting quality problems or safety accidents caused by positional deviations. Alarm 13 is communicatively connected to control box 14. When control box 14 detects an abnormal situation, such as limit switch 15 being triggered or solenoid valve 12 malfunctioning, it will immediately activate alarm 13 to remind operators to take timely measures. The alarm 13 effectively improves operators' safety awareness and reduces the risk of accidents caused by negligence.

[0027] Reference Figure 1 and Figure 2The support assembly 2 includes a base 21, a lifting rod 22, and a support platform 24. The base 21 is the fundamental component of the support assembly 2, used to bear the weight of the entire support assembly 2 and provide stable support. The base 21 includes a first end face 211 and a second end face 212 disposed opposite to each other. A roller device 2121 is mounted on the second end face 212, which is used to realize the movement of the support assembly 2. In this embodiment, the roller device 2121 includes multiple rollers, of which at least two are omnidirectional wheels and two are brake wheels, allowing the support assembly 2 to move and stop flexibly. The lifting rod 22 is disposed on the first end face 211 of the base 21 and extends upwards, used to adjust the height of the support assembly 2 to accommodate steel plates of different thicknesses and the height differences of the cutting platform. In this embodiment, the lifting rod 22 includes an inner rod 221 and an outer rod 222. The inner rod 221 is slidably sleeved in the inner cavity of the outer rod 222. By adjusting the position of the inner rod 221 in the outer rod 222, the height of the lifting rod 22 can be adjusted. Specifically, the bottom of the inner rod 221 and the top of the outer rod 222 are provided with multiple sets of corresponding through holes. These through holes are evenly distributed along the axial direction of the circular tube for inserting bolts. By loosening the bolts, the insertion depth of the inner rod 221 in the outer rod 222 can be freely adjusted, thereby changing the overall height of the lifting rod 22. The support platform 24 is the top component of the support assembly 2. The support platform 24 is swayably connected to the end of the lifting rod 22 away from the base 21 via the swing assembly 23, and the tilt angle of the support platform 24 can be adjusted according to cutting requirements. The swing assembly 23 includes a first connecting plate 231, a second connecting plate 232, and a first connecting member 233. The first connecting plate 231 and the second connecting plate 232 are symmetrically arranged on both sides of the lifting rod 22 and connected to the side of the support platform 24 near the lifting rod 22. The first connecting member 233 is sequentially inserted through the first connecting plate 231, the lifting rod 22, and the second connecting plate 232. By adjusting the first connecting member 233, the support platform 24 can be fixed and its angle adjusted. The support platform 24, on the side away from the lifting rod 22, is provided with at least one limit block 241 that cooperates with the limit switch 15. The limit block 241 is used to determine the stopping position of the cutting trolley 11. When the cutting assembly 1 moves to the position of the limit block 241, the limit switch 15 is triggered by the limit block 241 and sends a stop signal to the control box 14. The control box 14 controls the cutting assembly 1 to stop working according to the stop signal. In an optional embodiment of this example, the limit switch 15 is triggered physically. The limit switch 15 is located on the side of the cutting trolley 11, and the shortest distance from the bottom of the cutting trolley 11 to the limit switch 15 is less than or equal to the distance from the top of the limit block 241 to the support platform 24. Specifically, as the cutting trolley 11 moves along the cutting path, when the limit switch 15 at its front end or side contacts the limit block 241, the limit switch 15 is pushed or compressed, triggering the limit switch 15.The microswitch or relay inside the limit switch 15 actuates, closing the circuit and sending a stop signal to the control box 14. In another optional embodiment of this example, the limit switch 15 is triggered by induction. The limit switch 15 has a sensing head. When the cutting assembly 1 moves to the position of the limit block 241, the sensing head detects the signal of the limit block 241, thereby triggering the limit switch 15. The microswitch or relay inside the limit switch 15 actuates, closing the circuit and sending a stop signal to the control box 14. Optionally, the limit block 241 is made of ferromagnetic material. The support platform 24 also includes a groove 242, which is located on the side of the support platform 24 away from the lifting rod 22. A magnet 2421 is provided in the groove 242, and the limit block 241 is attracted to the magnet 2421. This design facilitates the installation and replacement of the limit block 241 and also ensures the stability of the limit block 241 during the cutting process.

[0028] Reference Figures 1 to 3 Preferably, the cutting auxiliary device of this embodiment includes at least two cutting components 1 and at least two support components 2. It can simultaneously cut at least two edges to be cut, enabling one person to operate multiple machines in parallel, thus improving work efficiency. For example, the operator places the cutting plate to be cut on the cutting platform and, according to the cutting requirements, places multiple cutting components 1 on the starting points of different edges to be cut on the cutting plate. Through the control box 14, the operator can simultaneously start multiple cutting components 1, each cutting component 1 running independently along a predetermined path to complete its respective cutting task. Each support component 2 is adjusted according to the cutting endpoint position of the cutting component 1. The operator adjusts the height of the support platform 24 using the lifting rod 22 to ensure it is lower than the height of the cutting platform. The simultaneous operation of multiple cutting components 1 can significantly shorten the cutting time and improve overall work efficiency. Through the design of automated control and limit switches 15, operator intervention during the cutting process is reduced, lowering labor intensity. Each cutting component 1 and support component 2 is equipped with an independent limit switch 15 and an alarm 13, ensuring the safety of the cutting process.

[0029] The cutting auxiliary device provided by this invention achieves efficient and automated cutting operations through an integrated cutting component 1 and support component 2. The cutting component 1 is equipped with a control box 14, a solenoid valve 12, an alarm 13, and a limit switch 15, ensuring precise control and safe operation of the cutting process. The height-adjustable design of the support component 2 allows it to adapt to cutting plates and platforms of different thicknesses, improving the versatility and stability of the cutting auxiliary device. The automatic stop function of the limit switch 15 effectively avoids over- or under-cutting, ensuring cutting quality and operational safety. Furthermore, the cutting auxiliary device of this invention can include multiple cutting components 1 and multiple support components 2, supporting one person operating multiple machines in parallel, significantly improving production efficiency and reducing labor costs. Overall, the cutting auxiliary device of this invention is easy to operate and maintain, possessing high practicality and economy, and is suitable for various industrial cutting scenarios.

[0030] Example 2

[0031] Reference Figures 1 to 4 This embodiment provides a method for using a cutting auxiliary device. The method for using the cutting auxiliary device in this embodiment adopts the cutting auxiliary device described in Embodiment 1 and includes the following steps: S100: Place the cutting plate to be cut on the cutting platform; Place the cutting plate to be cut on the cutting platform, ensuring that the surface of the cutting plate is flat and free from obvious deformation. The placement of the cutting plate should be adjusted according to the requirements of the cutting path, so that the edge to be cut is parallel to the edge of the cutting platform.

[0032] S200: The cutting component is placed on the cutting platform and positioned at the starting point of the edge to be cut on the cutting plate, and the support component is placed at the ending point of the edge to be cut. Install cutting assembly 1 on the cutting platform and position it at the starting point of the edge to be cut on the cutting plate. The installation position of cutting assembly 1 should ensure that its cutting tool can be accurately aligned with the cutting starting point. Simultaneously, install support assembly 2 at the ending point of the edge to be cut on the cutting plate. The installation position of support assembly 2 should be adjusted according to the end point of the cutting path to ensure that it can provide stable support for cutting assembly 1 when it reaches the cutting end point.

[0033] S300: Adjust the height of the support platform of the support assembly by means of the lifting rod of the support assembly until the height of the support platform is lower than the height of the cutting platform; Specifically, the design of the lifting rod 22 allows the operator to flexibly adjust it according to the height of the cutting platform and the thickness of the cutting plate. During adjustment, the operator should ensure that the height of the support platform 24 is lower than the height of the cutting platform so that the cutting assembly 1 can smoothly move onto the support platform 24. In this embodiment, the height difference between the support platform 24 and the cutting platform is between 1 mm and 10 mm. The specific adjustment process of the lifting rod 22 is as follows: First, loosen the bolts on the lifting rod 22 to allow the inner rod 221 to slide freely within the cavity of the outer rod 222. Then, adjust the insertion depth of the inner rod 221 in the outer rod 222 until the height of the support platform 24 is lower than the cutting platform. Finally, tighten the bolts to lock the relative position of the inner rod 221 and the outer rod 222, ensuring the stability of the support platform 24 during the cutting process.

[0034] S400: Start the cutting assembly. When the cutting assembly moves to the position of the limit block on the support platform, the limit switch of the cutting assembly is triggered and sends a stop signal to the control box of the cutting assembly. The control box controls the cutting assembly to stop moving according to the stop signal.

[0035] Specifically, the cutting assembly 1 is started, causing it to move along the edge to be cut on the cutting plate. The cutting assembly 1 can be started via the operating interface on the control box 14, allowing the operator to set parameters such as cutting speed and gas flow rate according to cutting requirements. During the cutting process, the operating status of the cutting assembly 1 is monitored in real time by the control box 14. When the cutting assembly 1 reaches the position of the limit block 241 on the support platform 24, the limit switch 15 of the cutting assembly 1 is triggered. The limit switch 15 is communicatively connected to the control box 14; after being triggered by the limit block 241, the limit switch 15 immediately sends a stop signal to the control box 14. Upon receiving the stop signal, the control box 14 performs the following operations: Control the solenoid valve 12 to cut off the supply of cutting gas, so that the cutting assembly 1 stops cutting; Activate alarm 13 to remind the operator that the cutting operation has been completed; Control the cutting component 1 to stop moving, ensuring that the cutting component 1 stops accurately at the position of the limit block 241.
