[0002] Photovoltaic brackets are used to support and secure photovoltaic modules, ensuring they receive sunlight at the optimal angle and position, thereby achieving efficient energy conversion. During their production, photovoltaic brackets are forged using cold heading machines. Current cold heading machines use rotating clamps to clamp and adjust the photovoltaic brackets. These clamps typically use a bidirectional screw to rotate and move two clamping rods to clamp the photovoltaic brackets. However, the bidirectional screws require manual lubrication and maintenance, which takes a long time.

[0003] In order to improve the maintenance efficiency of the rotary clamp, the utility model with patent publication number CN219561277U discloses a cold heading machine rotary clamp, which can not only drive the rack to move by rotating the missing gear, and then drive the connecting rod to move to extrude the inclined block, but also can adjust the position of the rack by adjusting the telescopic rod, thereby controlling the oil supply work. Although it is convenient for oiling the bidirectional screw, it sprays oil on the bidirectional screw through an oil distribution pipe and multiple telescopic nozzles during oiling. The oil spraying direction is single, which is not convenient for all-round oiling of the bidirectional screw, thereby easily reducing the maintenance effect of the cold heading machine rotary clamp.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

On the two protective baffles 4, the protective baffles 4 can protect the oiling process. At the same time, the sprayed lubricating oil can be rebounded through the protective baffles 4 so that the lubricating oil can be sprayed on the bidirectional screw 1 again. The oil supply airbag 6 is installed at the top of the protective cylinder 3, and an oil supply assembly is provided between the oil supply airbag 6 and the multiple oiling nozzles 5. The pressure plate 7 is raised and lowered on the upper side of the oil supply airbag 6. The top of the oil supply airbag 6 is connected to the oil inlet pipe 24, and the oil inlet pipe 24 is detachably connected to the dust cover 25. The oil inlet pipe 24 is convenient for replenishing lubricating oil into the oil supply airbag 6.

Both protective baffles 4 are provided with moving openings that match the sliding plate 22 and the clamping rod 2. The protective baffle 4 will not affect the movement of the sliding plate 22 and the clamping rod 2.

[0045] like Figures 1 to 5 As shown, the oil supply assembly includes a choke bend 8, a telescopic tube 9 and a connecting pipe 10. The choke bend 8 is provided with two, and the two choke bends 8 are respectively connected to the two sides of the oil supply airbag 6. The telescopic tube 9 is connected to each choke bend 8. The choke bend 8 is concave, which can prevent the lubricating oil from entering the telescopic tube 9 when the oil supply airbag 6 is in a normal state. The telescopic tube 9 is connected to the protective tube 3 through the connection. There are two connecting pipes 10, one of which is connected to the telescopic tube 9, and multiple oil supply pipes 11 are connected between the two connecting pipes 10 and the adjacent multiple oiling nozzles 5.

[0047] like Figures 1 to 5As shown, the adjustment assembly includes a double-headed electric cylinder 12, an adjustment bar 13 and an adjustment frame 15.

The adjustment plate 14 is fixedly connected to each adjustment bar 13. There are two adjustment frames 15, and the two adjustment frames 15 are fixedly connected between the adjustment plate 14 and the adjacent protective baffle 4. A through-hole matching the connecting pipe 10 is provided on the adjustment frame 15. The top end of the adjustment bar 13 is fixedly connected to the limit block 26. The protective cylinder 3 is provided with a limit groove for the limit block 26 to slide, which can limit the adjustment bar 13 in the protective cylinder 3;

[0048] By pushing the two adjustment bars 13 through the double-headed electric cylinder 12, the adjustment plate 14 can drive the adjustment frame 15 to move, so that the adjustment frame 15 can drive the connecting pipe 10 to move, thereby facilitating the adjustment of the position of the protective baffle 4 and the oiling nozzle 5.

[0049] like Figures 1 to 5 As shown, the drive seat includes a mounting box 16, a motor 17, a fixed block 18 and a rotating column 19. The mounting box 16 is fixedly connected to one side of the protective tube 3, the motor 17 is installed in the mounting box 16, and the output end of the motor 17 passes through the side wall of the protective tube 3 and is fixedly connected to the bidirectional screw 1. A mounting opening is provided on one side of the mounting box 16, and a mounting cover 28 is detachably connected to the mounting opening. A pull ring 29 is fixedly connected to the mounting cover 28, and the mounting cover 28 is opened by the pull ring 29 for easy maintenance of the motor 17. The fixed block 18 is fixedly connected to the other side of the protective tube 3, the rotating column 19 is fixedly connected to one side of the bidirectional screw 1, and a rotating opening for the rotating column 19 to rotate is provided on the fixed block 18. A rotating plate 27 is fixedly connected to one side of the rotating column 19, and a rotating groove for the rotating plate 27 to rotate is provided on the fixed block 18, so as to increase the stability of the rotating column 19 in the rotating opening.

[0050] The bidirectional screw 1 is rotated by the motor 17, and the rotating column 19 drives the rotating plate 27 to rotate on the fixed block 18, so as to increase the stability of the rotation of the bidirectional screw 1. Through the rotation of the bidirectional screw 1, the two clamping rods 2 will move toward each other, so that the photovoltaic bracket can be stably clamped by the two clamping rods 2 when the cold heading machine is working.

[0051] like Figures 1 to 5 As shown, an electric push rod 20 is installed on the top of the protective tube 3, and a pressure frame 21 is fixedly connected between the output end of the electric push rod 20 and the pressure plate 7;

[0052] By pushing the pressure frame 21 through the electric push rod 20 , the pressure plate 7 can be pressed against the oil supply airbag 6 so that the lubricating oil in the oil supply airbag 6 can flow into the two choke bends 8 .

[0053] In this embodiment, when the photovoltaic bracket needs to be clamped during the operation of the cold heading machine, the bidirectional screw 1 is rotated by the motor 17, so that the two clamping rods 2 move toward each other, and the photovoltaic bracket can be stably clamped by the two clamping rods 2. When it is necessary to spray lubricating oil on the bidirectional screw 1, the two adjustment bars 13 are moved toward each other by the bidirectional electric cylinder, so that the two adjustment bars 13 drive the two adjustment plates 14 and the two protective baffles 4 to move toward each other. When the protective baffles 4 move to the appropriate position, the pressure frame 21 is moved by the electric push rod 20, so that the pressure frame 21 drives the pressure plate 7 to move, and the oil supply airbag 6 is squeezed by the pressure plate 7. Then, the lubricating oil in the oil supply airbag 6 will enter the connecting pipe 10 through the flow-blocking bend 8 and the telescopic tube 9, so that the lubricating oil can enter the multiple oiling nozzles 5 through multiple oiling nozzles, so that the bidirectional screw 1 can be sprayed with all-round oil.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
