[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 5 As shown, this utility model provides an automatic positioning and punching device for C-shaped steel processing, including an operating table 1, a support frame 3 fixedly connected to the top of the operating table 1, a punching component 2 fixedly connected to the lower inner wall of the support frame 3, and a fixing component 4 fixedly connected to the top of the operating table 1.

[0028] The drilling assembly 2 includes a telescopic cylinder 22, which is fixedly connected to the support frame 3. The output end of the telescopic cylinder 22 passes through the top of the support frame 3 and is fixedly connected to a lifting plate 23. Two connecting rods 24 are slidably connected to the inner surface of the lifting plate 23. A pressure plate 25 is fixedly connected to the bottom end of the two connecting rods 24. A cushioning pad is fixedly connected to the bottom end of the pressure plate 25. A buffer spring 241 is wound around the outer surface of both connecting rods 24. The two ends of the pressure plate 25 and the lifting plate 23 are respectively connected to the two sides of the support frame 3. The inner wall is slidably connected, and the bottom end of the lifting plate 23 is fixedly connected to a punching rod 21. The bottom end of the punching rod 21 passes through the pressure plate 25 and extends to the lower part of the pressure plate 25. The air cylinder can precisely control the lifting and lowering movement of the punching rod 21 to realize automated punching operation. When the pressure plate 25 is used to punch the material, the pressure plate 25 can disperse the impact force at the moment of punching, effectively reduce the stress concentration generated during punching, and avoid the C-shaped steel from deforming due to excessive local stress, thereby significantly improving the punching quality and dimensional accuracy of the C-shaped steel.

[0029] Specifically, guide grooves 26 are provided on both inner walls of the support frame 3, and guide blocks 243 that cooperate with the guide grooves 26 are fixedly connected to both ends of the pressure plate 25 and the lifting plate 23, ensuring that the pressure plate 25 and the lifting plate 23 move along the predetermined trajectory during the lifting process, ensuring that the drilling rod 21 rises and falls vertically, and improving the drilling accuracy.

[0030] like Figures 1 to 5 As shown, the top ends of both connecting rods 24 are fixedly connected to limit plates 244. The end of the pressure plate 25 corresponding to the lifting plate 23 is provided with a spring receiving groove 242 for use with the buffer spring 241. The limit plate 244 can prevent the connecting rods 24 from coming out of the lifting plate 23, ensuring the safety of the device. The spring receiving groove 242 provides a receiving space for the buffer spring 241 when it is squeezed by the pressure plate 25 and the lifting plate 23, avoiding damage due to excessive squeezing.

[0031] Furthermore, the fixing component 4 includes a fixing platform 49. The top of the fixing platform 49 has two long slots 46. The inner walls of both sides of one of the long slots 46 are rotatably connected to a bidirectional lead screw 42. One end of the bidirectional lead screw 42 passes through the long slot 46 and is fixedly connected to a rotating handle 41. Clamping plates 45 are threaded onto the threads of the bidirectional lead screw 42 in different directions. Several rotating rollers 44 are rotatably connected to the opposite ends of the two clamping plates 45. The outer surface of the rotating rollers 44 is provided with shock-absorbing pads to clamp and position C-shaped steel of different sizes. The rotating rollers 44 are designed to facilitate the movement and adjustment of the C-shaped steel.

[0032] like Figures 1 to 5 As shown, the inner walls of the two sides of another long groove 46 are fixedly connected with a sliding rod 48. The outer surface of the sliding rod 48 is slidably connected to the two clamping plates 45, which ensures the straightness and stability of the clamping plates 45, avoids the clamping plates 45 from shifting during movement, and further ensures the accuracy of fixing the C-shaped steel.

[0033] It is worth noting that the two clamps 45 are provided with a punching frame 50 at one end of their respective sides. The top of the punching frame 50 is provided with a punching groove 43, and one end of the punching frame 50 is provided with a cleaning groove 47. The punching groove 43 provides an accurate punching position reference for the punching operation, making the punching more precise. The cleaning groove 47 is conducive to collecting and discharging waste during the punching process, keeping the working area clean, and avoiding the accumulation of waste that affects the punching operation.

[0034] like Figures 1 to 5 As shown, the lower inner wall of the cleaning groove 47 is inclined. The cleaning groove 47 is connected to the drilling groove 43. The inclined design of the wall of the cleaning groove 47 is conducive to the automatic discharge of waste under the action of gravity, which improves the efficiency of waste cleaning, reduces the workload of manual cleaning, and ensures the continuous operation of drilling.

[0035] The telescopic cylinder 22 is existing technology and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this utility model is common knowledge in the field, and its working principle is already known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0036] Working principle and process: When drilling holes in C-shaped steel, first, the C-shaped steel is fastened onto two clamping plates 45. By rotating the handle 41, the double-acting screw 42 is driven, and the clamping plates 45 are guided by the rotating roller 44 to clamp and position the C-shaped steel. Then, the telescopic cylinder 22 is activated, which pushes the lifting plate 23 downward along the guide groove 26, driving the drilling rod 21 through the pressure plate 25 into the drilling groove 43 of the drilling frame 50 to perform the drilling operation. During the drilling process, the drilling plate will first contact the C-shaped steel under the action of the buffer spring 241, which facilitates the fixation of the C-shaped steel and prevents deformation of the C-shaped steel due to excessive local stress. The waste generated by drilling will pass through the cleaning groove 47 of the drilling groove 43. The inclined inner wall of the cleaning groove 47 facilitates the automatic sliding of the waste.
