Fixed seats 314 are fixedly installed on opposite ends of the top of the two slide blocks 312. Bow-shaped frames 304 are fixedly installed on the top of the two fixed seats 314. There are two clamping plates 307. Mounting plates 310 are fixedly installed on opposite sides of the two clamping plates 307 near the bottom. A connecting plate 303 is provided at the bottom center of the slide blocks 312. A connecting seat 302 is provided at the end of the two connecting plates 303 away from the slide blocks 312. A pneumatic telescopic rod 313 is fixedly installed on the right side of the connecting seat 302. A fixed seat 314 is fixedly installed at the bottom right center of the operating table 2.

[0023] Specifically, the two connecting plates 303 are connected to the connecting seat 302 and the two sliders 312 respectively by pins.

[0024] Specifically, the end of the pneumatic telescopic rod 313 furthest from the output end is fixedly connected to the left side of the fixed base 314.

[0025] Specifically, a second positioning pin 317 is fixedly installed on the top of one of the two mounting plates 310 near the left side, a second pin 321 is fixedly installed on the top of one of the two mounting plates 310 near the left side, and a second pin 321 is fixedly installed on the top of the other of the two mounting plates 310 near the left side, and a second positioning pin 317 is fixedly installed on the top of the other of the two mounting plates 310 near the left side.

[0026] Specifically, a first positioning pin 316 is fixedly installed on the top right side of the operating platform 2 near the rear end. A first swing frame 318 is provided on the outer surface of the first positioning pin 316 near the rear end of the top right side of the operating platform 2. A first pin 320 is fixedly installed on the top left side of the operating platform 2 near the rear end. A second swing frame 319 is provided on the outer surface of the first positioning pin 316 near the top right side of the operating platform 2. There are two of each of the second swing frame 319, the first swing frame 318, and the first pin 320. The connection between the first swing frame 318 and the first positioning pin 316 is connected by a ball bearing, and the connection between the first pin 320 and the second swing frame 319 is connected by a ball bearing.

[0027] Specifically, the two ends of the two bow-shaped frames 304 are connected to the adjacent first swing frame 318 and second swing frame 319 respectively by pins.

[0028] Specifically, the opposite ends of the two clamping plates 307 are fixedly connected to the adjacent sides of the first slide bar 301 and the second slide bar 311, respectively, and a controller is provided on the mounting bracket 1.

[0029] Specifically, the first slide rod 301, connecting seat 302, connecting plate 303, bow-shaped frame 304, fixing plate 305, first mounting seat 306, clamping plate 307, second mounting seat 308, fixing block 309, mounting plate 310, second slide rod 311, slider 312, hydraulic telescopic rod, fixing seat 314, slide rail 315, first positioning pin 316, second positioning pin 317, first swing frame 318, second swing frame 319, first pin 320 and second pin 321 constitute the clamping mechanism 3.

[0030] In use, the pneumatic telescopic rod 313 is activated, and its output end drives the connecting seat 302 to move. This movement of the connecting seat 302 causes the connecting plate 303 and the end adjacent to the connecting seat 302 to swing in opposite directions. As the output end of the pneumatic telescopic rod 313 continues to advance, the two sliders 312 swing along the slide rail 315 to both ends. The two sliders 312 respectively drive the two fixed blocks 309 and the bow-shaped frame 304 to move forward and backward respectively. The two bow-shaped frames 304 move to both sides, thereby causing the two first swing frames 318 and the second swing frame 319 to swing relative to the first positioning pin 316 and the first pin 320, respectively. This causes the mounting plate 310 and the clamping plate 307 to expand to both ends. As the mounting plate 310 and the clamping plate 307 move, the first slide rod 301 and the second slide rod 311 swing along the first mounting seat 306 and the second... The mounting base 308 moves, and the operator places the steel structure to be clamped on the operating table 2 between the two clamping plates 307. After placement, the output end of the pneumatic telescopic rod 313 is retracted, thereby moving the connecting base 302. The movement of the connecting base 302 causes the connecting plate 303 to swing towards the adjacent end of the connecting base 302 with the end of the connecting plate 303 as the center. As the output end of the pneumatic telescopic rod 313 continues to retract, the two sliders 312 move towards the center along the slide rail 315. The two sliders 312 drive the two fixed blocks 309 and the bow-shaped frame 304 to move towards the center. The movement of the two bow-shaped frames 304 towards the center causes the two first swing frames 318 and the second swing frame 319 to swing with the first positioning pin 316 and the first pin 320 as limits, thereby moving the mounting plate 310 and the clamping plate 307 towards the center, thus clamping the steel structure.

[0031] In summary, this steel structure processing fixture, through the setting of fixture mechanism 3 and the coordinated action of components such as pneumatic telescopic rod 313, slider 312, slide rail 315, bow frame 304, swing frame, and clamping plate 307, can achieve a firm clamping of steel structure components. Precise control of the pneumatic telescopic rod 313 allows the clamping force to be adjusted as needed, ensuring that the steel structure components will not loosen or shift during processing, thereby improving processing accuracy and quality. The fixture mechanism 3 is rationally designed to adapt to steel structure components of different sizes and shapes. By adjusting the position and clamping force of the clamping plate 307, various processing requirements can be met. This adaptability allows the fixture to play a good role in different processing scenarios, improving the versatility and flexibility of the equipment. The operation of fixture mechanism 3 is simple and easy to control; the operator only needs to operate the pneumatic telescopic rod 313 through the controller to realize the expansion and clamping action of the clamping plate 307. This automated operation not only saves manpower but also improves work efficiency and reduces the possibility of human error.
