[0023] This utility model provides, for example Figures 1-4The illustrated photovoltaic square tube length-cutting device is particularly suitable for cutting square tubes. It can achieve precise length-cutting of photovoltaic square tubes of different sizes and lengths, effectively improving cutting efficiency and accuracy, and meeting the square tube processing needs of the photovoltaic processing field. Specifically, it includes a cutting table 1, which is fixedly installed on the ground. The cutting table 1 serves as the installation foundation and working platform of the entire device and is made of high-strength alloy material to ensure sufficient structural stability and load-bearing capacity, avoiding the impact of table shaking on cutting accuracy during the cutting process.

[0024] A cross frame 4 is installed above the cutting table 1. The cross frame 4 has a cross structure, and a vertical frame 3 is fixedly connected to the intersection by welding. The vertical frame 3 is a vertical column structure. The bottom end of the vertical frame 3 is detachably fixed to the cutting table 1 by bolts. This connection method not only ensures the firmness of the connection between the vertical frame 3 and the cutting table 1, but also facilitates the disassembly and maintenance of the device in the future.

[0025] To accommodate square tubes of different sizes, the cross frame 4 is designed with four ends of equal length, each with a sliding groove. Simultaneously, the device is equipped with four telescopic plates 6, whose shape matches the internal structure of the sliding grooves. The four telescopic plates 6 are slidably positioned at the four ends of the cross frame 4 via the sliding grooves, allowing them to slide freely along the length of the cross frame 4 ends, thus achieving telescopic adjustment.

[0026] A circular sleeve 7 is fixedly connected to the end of the telescopic plate 6 away from the cross frame 4 by welding. The circular sleeve 7 has a certain length and is a hollow cylindrical structure with a smooth inner wall to reduce sliding friction. A corner frame 9 is provided on the side of the circular sleeve 7. The corner frame 9 is L-shaped and made by one-piece molding process. The corner frame 9 has two ends of the same length. A through groove 8 that matches the outer diameter of the circular sleeve 7 is opened at the corner of the corner frame 9. The through groove 8 runs through both sides of the corner frame 9. The circular sleeve 7 is fixedly connected to the inside of the through groove 8 by welding to ensure that the circular sleeve 7 and the corner frame 9 are tightly connected and can move synchronously.

[0027] Square slots 10 are provided at both ends of the corner bracket 9, and the square slots 10 are opened along the length direction of the ends of the corner bracket 9. A connecting plate 11 is slidably arranged between the two corresponding square slots 10. The two ends of the connecting plate 11 are respectively embedded in the two corresponding square slots 10 and can slide freely within the square slots 10. Through the connecting action of the connecting plate 11, the four corner brackets 9 form a linkage structure, ensuring the consistency of the movement of the four corner brackets 9 during the adjustment process, thereby ensuring the stability of the square tube fixation.

[0028] The inner side of the sleeve 7 is equipped with a limiting rod 12. The limiting rod 12 is a cylindrical structure with an outer diameter that matches the inner diameter of the sleeve 7. The length of the limiting rod 12 is greater than the length of the sleeve 7. This design ensures that when the limiting rod 12 slides inside the sleeve 7, a part of the rod always extends out of the sleeve 7 and can effectively abut against the inner corner of the square tube, thereby achieving the positioning of the square tube.

[0029] To drive the telescopic plate 6 to move and adjust the position of the limit rod 12, an electric push rod 13 is bolted to one of the telescopic plates 6 on the cross frame 4. The telescopic direction of the electric push rod 13 is consistent with the sliding direction of the corresponding telescopic plate 6, and the telescopic plate 6 is fixedly connected to the telescopic end of the electric push rod 13 by a flange.

[0030] When the electric push rod 13 is activated, its telescopic end drives the corresponding telescopic plate 6 to slide along the sliding groove at the end of the cross frame 4. Under the linkage of the connecting plate 11, the other three telescopic plates 6 move synchronously, thereby driving the four corner frames 9 to move synchronously closer to or further away from the center position of the cross frame 4, realizing the synchronous adjustment of the positions of the four limiting rods 12, which is suitable for fixing square tubes with different side lengths. At the same time, the limiting rods 12 can slide axially inside the round sleeve 7, and can adjust their position according to the length direction of the square tube, ensuring that the inner corners of square tubes of different lengths can form a stable abutment, clamping and fixing the square tube from the inside out, and preventing the square tube from shifting during the cutting process.

[0031] The electric push rod 13 is connected to the factory's power supply. A pressure sensor is installed on the limit rod 12. Specifically, a controller can be set to connect between the electric push rod 13 and the pressure sensor. When the pressure sensor detects that the squeezing force has reached the set threshold, it transmits this information to the controller. The controller controls the electric push rod 13 to stop extending to prevent excessive squeezing. The controller and its control principle are common existing technologies and will not be described in detail here.

[0032] In summary, this utility model, by setting up structures such as cross brackets 4 and corner brackets 9, clamps and fixes the square tube from the inside out, preventing indentations or damage, and realizes the synchronous adjustment of the four limiting rods 12. It is suitable for square tubes of different sizes and improves the efficiency of the square tube fixed length cutting device.

[0033] Meanwhile, the limiting rod 12 can slide axially inside the sleeve 7, and its position can be adjusted according to the length direction of the square tube, ensuring that a stable contact can be formed at the inner corners of square tubes of different lengths.

[0034] Above the cutting table 1 is a cutting device 2. The cutting device 2 can be a high-speed cutting saw specially designed for photovoltaic square tube processing. Its cutting blade is treated with special materials and has wear-resistant and high-temperature resistant properties, which can quickly and accurately complete the cutting of square tubes.

[0035] A sliding channel 14 is provided on the cutting table 1. A slide block 17 is slidably installed inside the sliding channel 14. The shape of the slide block 17 is perfectly matched with the internal contour of the sliding channel 14. The width and depth of the sliding channel 14 are precision milled, and a layer of wear-resistant alloy liner is laid at the bottom of the channel. The surface of the liner is polished, which not only avoids wear of the channel caused by long-term sliding of the slide block 17, but also reduces sliding resistance, providing a smooth and non-offset movement guide for the slide block 17, and ensuring the axial accuracy of fixed-length cutting from the basic structure.

[0036] A mounting platform 5 is provided on the slide 17. An electric slide rail (not shown in the figure) is installed between the mounting platform 5 and the slide 17 as a feed control structure. The track of the electric slide rail is rigidly fixed to the top surface of the slide 17 by bolts. The length direction of the track is completely perpendicular to the length direction of the sliding channel 14. Anti-detachment guards and travel limit blocks are provided on both sides of the track to prevent the slide rail slider from detaching from the track and to avoid collision damage caused by excessive feed of the cutting device 2. The slider of the slide rail is integrally connected to the bottom of the mounting platform 5. The slider integrates a precision planetary gear transmission mechanism and an absolute encoder, which can provide real-time feedback on the movement distance of the mounting platform 5 to ensure that the feed of the cutting device 2 is accurate and controllable, and to meet the requirements of cut flatness for fixed-length cutting. The cutting device 2 is fixedly installed on the mounting platform 5 by bolts. A shock-absorbing pad is installed between the bottom of the device and the mounting platform 5 to reduce the vibration transmitted to the slide 17 during operation of the cutting device 2, and to avoid vibration affecting the fixed-length positioning accuracy.

[0037] To drive the slide block 17 to move precisely along the sliding channel 14 and achieve fixed-length positioning of the cutting position, a drive assembly is provided on the cutting table 1, and a control system is provided to cooperate with the drive assembly. The drive assembly includes a lead screw 15 and a motor 16. The lead screw 15 is rotatably mounted on the cutting table 1 and is distributed along the length direction of the sliding channel 14. The slide block 17 has a threaded hole that mates with the lead screw 15. The motor 16 is fixedly mounted on the cutting table 1. The motor 16 is a servo motor, and the lead screw 15 is fixedly connected to the drive shaft of the motor 16.

[0038] The control system mainly includes a main controller (such as a PLC / industrial microcontroller), input / output modules (including a touch screen and encoder), and drive modules (motor drivers). During operation, the operator first presets the target length parameters of the square tube to the main controller through the input modules such as the touch screen. The main controller calculates the number of rotations required by the motor 16 based on the lead of the lead screw 15, and then sends a command to the motor 16 through the drive module to control the lead screw 15 to rotate so as to drive the slide 17 to move precisely to the designated cutting position. At the same time, the motor encoder feeds back the speed and displacement data to the main controller in real time to form a closed-loop control to ensure the positioning accuracy of the slide 17. Finally, the main controller synchronously sends a signal to the electric slide rail drive module of the mounting platform 5 to control the cutting equipment 2 to feed radially to complete the cutting. The accuracy of fixed-length cutting is ensured throughout the process through the collaboration of hardware modules and software algorithms.
