Description

Technical Field

[0001] This utility model belongs to the field of semi-trailer box processing technology, and in particular relates to a positioning device for cutting steel in semi-trailer boxes. Background Technology

[0002] A semi-trailer is a type of truck consisting of a cab and a cargo box, distinct from a tractor-trailer. A semi-trailer has a rotatable joint between the cab and the cargo box, allowing the cab to detach from the cargo box and become an independent transport vehicle. Semi-trailers are widely used in logistics, construction sites, and other fields, and can carry various goods and heavy equipment. For easy unloading, the cargo box is usually equipped with a lifting device at the bottom, which tilts the cargo box to unload goods (e.g., grain, coal, sand, etc.). The manufacturing process of a semi-trailer requires a significant amount of steel, involving processes such as cutting, drilling, bending, and painting, and involves multiple steps to transform the steel into a semi-trailer body.

[0003] When processing semi-trailer bodies, square steel pipes are required, and these pipes need to be cut to the required lengths. This requires a cutting machine to process the pipes. During this process, it is crucial to ensure the stability of the pipes' position and prevent displacement. While bolts are sometimes used for positioning, this requires rotating the bolts, which is somewhat inconvenient. Therefore, a positioning device for cutting steel in semi-trailer bodies is needed. This device uses the reciprocating movement of clamping blocks to compress the square pipes placed on top of the processing table. The fixed clamping blocks also help to position the pipes during cutting, improving stability. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning device for cutting steel in a semi-trailer. By reciprocating the movement of the clamping block, it can squeeze the square tube placed on the top of the processing table. Under the limiting effect of the fixed clamping block, the square tube can be positioned during the cutting process, thereby improving the stability of the square tube cutting and solving the technical problems mentioned in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A positioning device for cutting steel in a semi-trailer includes a cutting table: a slide rail is fixedly connected to the top of the cutting table by bolts, a slider is slidably connected to the surface of the slide rail, clamping blocks are fixedly connected to the surface of the slider and the top of the cutting table, a motor is fixedly connected to the top of the cutting table by bolts, a rotating plate is fixedly connected to the output shaft of the motor by a flange, a U-shaped rod is welded to the surface of the clamping block on the left side, a connecting rod is welded to the bottom of the U-shaped rod, a frame plate is welded to the left end of the connecting rod, a rotary shaft is integrally formed on the surface of the rotating plate, a cutting assembly is installed on the top of the cutting table and a square steel pipe is placed thereon, and a main control box is fixedly installed on the top of the cutting table by bolts.

[0006] Preferably, the top end of the dial shaft extends into the inner cavity of the frame plate, and a rotating sleeve is rotatably connected to the surface of the dial shaft, with the surface of the rotating sleeve fitting against the inner wall of the frame plate.

[0007] Preferably, a cylinder is fixedly connected to the top of the cutting table by bolts, and a cylinder push plate is fixedly connected to the output end of the cylinder by a flange.

[0008] Preferably, a slide is slidably mounted on the top of the cutting table, and an infrared sensor is fixedly connected to the inner wall of the slide by bolts.

[0009] Preferably, the cylinder, cylinder push plate, and infrared sensor are all electrically connected to the main control box.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a motor to drive a rotating plate to rotate, which in turn moves a frame plate via a pivot shaft. The frame plate, through the cooperation of a connecting rod and a U-shaped rod, moves the clamping block on the left side to the right. At this time, under the limiting action of the clamping block on the right side, the square steel tube is positioned on the top of the cutting table. This achieves the purpose of squeezing the square tube placed on the top of the processing table by the reciprocating movement of the clamping block, and positioning the square tube during the cutting process under the limiting action of the fixed clamping block, thereby improving the cutting stability of the square tube.

[0012] 2. By using a rotating sleeve, this utility model provides padding protection between the pivot shaft and the inner wall of the frame plate, avoiding excessive wear when the two are in direct contact, thereby extending their service life.

[0013] 3. This utility model, through the combined use of cylinder one, cylinder push plate, slide table and infrared sensor, enables the square steel pipe to be fed automatically during cutting, which improves the convenience of the cutting process and effectively reduces the difficulty of processing.

The rotating shaft 10 is rotatably connected to a rotating sleeve 11. The surface of the rotating sleeve 11 fits against the inner wall of the frame plate 9. The rotating sleeve 11 provides padding protection between the rotating shaft 10 and the inner wall of the frame plate 9, avoiding excessive wear when the two are in direct contact, thereby extending their service life. The top of the cutting table 1 is equipped with a cutting assembly 16 and a square steel pipe 17. The top of the cutting table 1 is fixedly installed with bolts to the main control box 18.

[0024] Example 2:

[0025] Figure 1-4 This invention illustrates a positioning device for cutting steel in a semi-trailer, comprising a cutting table 1. A slide rail 2 is bolted to the top of the cutting table 1. A slider 3 is slidably connected to the surface of the slide rail 2. Clamping blocks 4 are fixedly connected to both the surface of the slider 3 and the top of the cutting table 1. A motor 5 is bolted to the top of the cutting table 1. A rotating plate 6 is fixedly connected to the output shaft of the motor 5 via a flange. A U-shaped rod 7 is welded to the surface of the clamping block 4 on the left side. A connecting rod 8 is welded to the bottom of the U-shaped rod 7. A frame plate 9 is welded to the left end of the connecting rod 8. A pivot shaft 10 is integrally formed on the surface of the rotating plate 6. A cylinder 12 is bolted to the top of the cutting table 1. The output end of cylinder 12 is fixedly connected to cylinder push plate 13 via flange. A slide table 14 is slidably installed on the top of cutting table 1. An infrared sensor 15 is fixedly connected to the inner wall of slide table 14 via bolts. Through the coordinated use of cylinder 12, cylinder push plate 13, slide table 14 and infrared sensor 15, the square steel pipe 17 can be fed by itself during cutting, which improves the convenience of the cutting process and effectively reduces the difficulty of processing. A cutting assembly 16 is installed on the top of cutting table 1 and square steel pipe 17 is placed on it. A main control box 18 is fixedly installed on the top of cutting table 1 via bolts. Cylinder 12, cylinder push plate 13 and infrared sensor 15 are all electrically connected to the main control box 18.

[0026] Working Principle: When using this invention, the user places the square steel pipe 17 below the cutting assembly 16. The motor 5 is then turned on, causing the rotating plate 6 to rotate. The rotating plate 6, via the pivot shaft 10, moves the frame plate 9. The frame plate 9, through the cooperation of the connecting rod 8 and the U-shaped rod 7, moves the clamping block 4 on the left side to the right. With the limiting action of the clamping block 4 on the right side, the square steel pipe 17 is positioned on the top of the cutting table 1. The cutting assembly 16 then cuts the square steel pipe 17. Finally, the main control box 18 controls the motor 5 to rotate the rotating plate 6 back to its original position. At this point, the infrared sensor 15 detects… The square steel tube 17 on the top of the cutting table 1 transmits signals to the main control box 18. At this time, the main control box 18 controls the cylinder 12 and the cylinder push plate 13, so that the cylinder push plate 13 approaches the slide table 14 and clamps the square steel tube 17. Then, the cylinder 12 moves the square steel tube 17 forward one station through the cylinder push plate 13. Then, referring to the above steps, the square steel tube 17 can be cut again. This realizes that by reciprocating the movement of the clamping block, it can squeeze the square tube placed on the top of the processing table. Under the limiting action of the fixed clamping block, the square tube can be positioned during the cutting process, which improves the stability of square tube cutting.

[0027] In summary, this positioning device for cutting steel in a semi-trailer uses a motor 5 to drive a rotating plate 6 to rotate. This rotating plate 6 then moves a frame plate 9 via a pivot shaft 10. The frame plate 9, through the cooperation of a connecting rod 8 and a U-shaped rod 7, moves the clamping block 4 on the left side to the right. At this time, under the limiting action of the clamping block 4 on the right side, the square steel tube 17 is positioned on the top of the cutting table 1. This achieves the goal of squeezing the square tube placed on the top of the cutting table by the reciprocating movement of the clamping block, and the positioning of the square tube during the cutting process is improved by the limiting action of the fixed clamping block.
