Obviously, the described embodiments are only some embodiments of the present invention, 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.

[0017] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of the invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0018] The following is a reference to the appendix. Figure 1 To be continued Figure 5 This invention describes a fully automated fixture for grinding H-beams in marine engineering.

[0019] like Figures 1 to 5As shown, a fully automated fixture for grinding H-beams in marine engineering includes: a first drive assembly 1, a first conveying assembly 2, multiple sets of stop assemblies 3, multiple sets of centering assemblies 4, a second drive assembly 5, a second conveying assembly 6, a third drive assembly 7, a third conveying assembly 8, a control assembly 9, and a first support 10, a second support 11, and a third support 12 arranged sequentially. The first driving component 1 and the first conveying component 2 are fixedly disposed at the upper end of the first bracket 10, and the first driving component 1 drives the first conveying component 2 to move. The second drive assembly 5 and the second conveying assembly 6 are fixedly disposed at the upper end of the second bracket 11, and the second drive assembly 5 drives the second conveying assembly 6 to move. The third drive assembly 7 and the third conveying assembly 8 are fixedly disposed at the upper end of the third bracket 12, and the third drive assembly 7 drives the third conveying assembly 8 to move. The first bracket 10, the second bracket 11 and the third bracket 12 are at the same height, and the centering component 4 and the stop component 3 are provided at the upper end of each bracket. The control component 9 is electrically connected to the first drive component 1, the stop component 3, the second drive component 5, the centering component 4 and the third drive component 7.

[0020] In this embodiment, by setting the control component 9 to be electrically connected to the first drive component 1, the stop component 3, the second drive component 5, the centering component 4 and the third drive component 7, the forward speed of the H-beam is automatically adjusted, and the stop component 3 and the centering component 4 are used for positioning to achieve precise positioning, thereby improving the production efficiency and quality of H-beam grinding.

[0021] Specifically, the first support 10, the second support 11 and the third support 12 are all made of high-strength steel, which has sufficient rigidity and stability to withstand the various forces generated by the steel during the grinding process.

[0022] Furthermore, the first conveying assembly 2 includes a plurality of first rollers mounted on the upper end of the first support 10 via bearings, and the first drive assembly 1 is connected to the plurality of first rollers via a transmission chain; Furthermore, the second conveying assembly 6 includes a plurality of second rollers mounted on the upper end of the second bracket 11 via bearings, and the second drive assembly 5 is connected to the plurality of second rollers via a transmission chain; Furthermore, the third conveying assembly 8 includes a plurality of third rollers mounted on the upper end of the third support 12 via bearings, and the third drive assembly 7 is connected to the plurality of third rollers via a transmission chain.

[0023] Specifically, the first roller, the second roller, and the third roller each include multiple driving rollers and multiple driven rollers. The driving rollers and the driven rollers are all mounted on the first support 10, the second support 11, or the third support 12 via bearings. The driving rollers are connected to the transmission chain, and a driven roller is provided between every two driving rollers. The driven rollers play the role of auxiliary support and conveying of the steel profiles.

[0024] Furthermore, such as Figure 3 and Figure 5 As shown, the stop assembly 3 includes a stop plate 301, a lifting cylinder 302, and a position sensor 303. The position sensor 303 is disposed at the upper end of the stop plate 301. The lifting cylinder 302 is fixedly disposed at the lower end of the first bracket 10, the second bracket 11, or the third bracket 12, and is used to drive the stop plate 301 to rise and fall. The position sensor 303 is electrically connected to the control assembly 9.

[0025] Specifically, after the steel profile is cut, it is conveyed to the barcode scanning area of ​​the grinding workstation via rollers, and the workpiece information is sent to the control component 9. The control component 9 controls the corresponding stop component 3 to rise according to the workpiece information. A detection switch is set in front of each stop component 3. When the position sensor 303 detects that the steel profile is about to reach the grinding station, it transmits a signal to the control component 9. The control component 9 controls the first drive component 1, the second drive component 5, or the third drive component 7 to decelerate in advance, so that it stops precisely at the grinding station, preventing hard damage to the steel profile and equipment, and meeting the automatic clamping requirements of different steel profile lengths and widths.

[0026] Furthermore, such as Figure 4 As shown, the centering component 4 includes two slide rails 401, two sets of centering sliders 402, and a drive unit 403. The two slide rails 401 are symmetrically arranged at the upper end of the first bracket 10, the second bracket 11, or the third bracket 12. The extension direction of the slide rails 401 is perpendicular to the extension direction of the second bracket 11. A set of centering sliders 402 is arranged opposite each other at the upper end of each slide rail 401. The drive unit 403 is fixedly arranged at the lower end of the first bracket 10, the second bracket 11, or the third bracket 12, and drives the centering sliders 402 to move along the slide rails 401.

[0027] Furthermore, a flexible contact pad is provided on the inner side of each set of opposing centering sliders 402.

[0028] Furthermore, the centering component 4 also includes a centering chain, and each group of centering sliders 402 is connected through the centering chain. The driving unit 403 drives the centering chain to drive each group of centering sliders 402 to move synchronously.

[0029] Specifically, a centering chain ensures synchronous operation on both sides of the centering component 4, and a guide rail 401 guides the movement to prevent the centering clamping device from tilting. When the steel section is stopped, the control component 9 controls the drive unit 403 to drive the centering slider 402 to move synchronously inward or outward, smoothly pushing the steel section to the center position of the fixture, achieving precise centering. The inner side of the centering slider 402 is provided with a flexible contact pad, which can effectively center the steel section while avoiding scratching its surface. Preferably, the drive unit 403 is a sliding cylinder.

[0030] Furthermore, the first drive component 1, the second drive component 5, and the third drive component 7 all employ variable frequency motors and reducers connected to the variable frequency motors.

[0031] Specifically, by controlling the motor speed through a frequency converter, the output speed of the motor can be precisely adjusted according to the conveying requirements of steel sections of different specifications, thereby achieving flexible adjustment of the roller conveying speed. The reducer is connected to the first, second, or third roller via a coupling and a drive shaft. The reducer, connected to the frequency converter motor, converts the motor's high-speed, low-torque output into a low-speed, high-torque output to meet the roller drive requirements. The coupling connects the reducer and the drive shaft, ensuring smooth power transmission and reducing vibration and impact. The drive shaft then transmits power to the rollers, driving them to rotate. The drive shaft is made of high-strength alloy steel, possessing excellent rigidity and wear resistance, ensuring stable and reliable operation over long periods.

[0032] Furthermore, the bottom of the first bracket 10, the second bracket 11, and the third bracket 12 are all provided with height adjustment components 13 to ensure that the first bracket 10, the second bracket 11, and the third bracket 12 are identical.

[0033] Furthermore, control component 9 adopts a collaborative architecture of industrial computer and programmable logic controller (PLC). The industrial computer is responsible for core data processing and strategy formulation, while the PLC executes logic control. Sensor groups (position / speed) collect steel profile parameters in real time, and actuators (motor drivers / cylinder solenoid valves) drive the rollers and clamps. Equipment interconnection is achieved through industrial Ethernet and wireless communication. The software system is developed based on a real-time operating system, integrating a human-machine interface (HMI) for parameter setting and status monitoring. The control algorithm module uses adaptive / fuzzy control to achieve precise speed adjustment, and the data management module supports production optimization analysis. The system features fully automated control: after the steel profile triggers position sensor 303, the rollers automatically start and stop and adjust speed according to different specifications; when positioned at the grinding station, precise and fully automated clamping occurs; after flipping, it is automatically clamped again by tooling; after completion, it automatically flows to the next process.

[0034] The working principle of the fully automated fixture for grinding H-beams in marine engineering is as follows: Control component 9 analyzes the length and width of the H-beam and automatically plans the clamping. When the H-beam needs grinding, it is placed at the starting end of the first support 10. The variable frequency motor is started, and the variable frequency motor drives the transmission chain to rotate through the reducer, thereby driving the drive roller to rotate and conveying the H-beam forward along the first support 10, the second support 11, and the third support 12. During the conveying process, the position sensor 303 monitors the position of the H-beam and transmits the signal to the control component 9 (PLC). After receiving the signal, the PLC immediately controls the corresponding stop plate 301 to rise. When the stop plate is at the corresponding grinding position, the control component 9 controls the sliding cylinder to drive the centering slider 402 to move, centering and clamping the H-beam, and the robot performs the grinding operation. After grinding is completed, the stop plate 301 is lowered, the centering component 4 releases the H-beam, the variable frequency motor starts again, and the ground H-beam is conveyed to the next process.

[0035] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
