Description

Technical Field

[0001] This utility model relates to the field of steel structure engineering construction technology, specifically to a cutting auxiliary device that facilitates fixing. Background Technology

[0002] Steel structure construction refers to the entire process of designing, fabricating, and installing buildings or other structures using steel as the primary structural material. Due to its high strength, lightweight, fast construction speed, and corrosion resistance, steel structures are widely used in industrial plants, bridges, commercial buildings, stadiums, and other fields.

[0003] Cutting devices are commonly used in steel structure construction. Cutting is a crucial step in the fabrication and installation of steel structures, typically used to cut steel to the dimensions and shapes required by the design for welding, connection, and assembly. According to design requirements, steel needs to be cut to specific sizes to ensure accurate assembly of components. Therefore, auxiliary fixing devices are necessary during the cutting process to secure the steel, prevent it from shifting during cutting, and ensure dimensional accuracy after cutting. In developing this utility model, the inventors discovered the following problems with the existing technology:

[0004] 1. Existing auxiliary fixing devices are all fixed together with a cutting platform. The connection method is usually riveting or welding, which makes the installation process cumbersome and inconvenient to disassemble.

[0005] 2. Most auxiliary devices are customized according to the size of the cutting platform and can only be adapted to one size of cutting platform. During installation, the overall attachment surface of the auxiliary fixing device cannot be adjusted according to the size of the cutting platform. Utility Model Content

[0006] The purpose of this utility model is to provide a cutting auxiliary device that is easy to fix, thereby solving the problems mentioned in the background art regarding the inability to quickly install and fix existing cutting auxiliary devices, the inconvenience of disassembly later, and the inability to adapt to various cutting platforms of different sizes during installation. To achieve the above objective, this utility model provides the following technical solution: a cutting auxiliary device that is easy to fix, including an assembly assembly, a left baffle welded to one side of the assembly assembly, a left limiting rod welded to the inner wall of the left baffle, a right limiting rod slidably connected inside the left limiting rod, a right baffle welded to one end of the right limiting rod, and a clamping assembly installed between the left baffle and the right baffle.

[0007] The assembly includes a fixing frame, a first lead screw is rotatably connected inside the fixing frame, a pressure plate is threaded onto the surface of the first lead screw, a vertical rod is welded inside the fixing frame near the first lead screw, an upper support rod and a lower support rod are rotatably connected to the surface of the vertical rod, and a rubber strip is rotatably connected to the other end of the upper support rod and the lower support rod.

[0008] More preferably, the clamping assembly includes a left clamping plate, a second lead screw is threadedly connected to the bottom of the left clamping plate, a connecting rod is slidably connected to one end of the second lead screw, a third lead screw is slidably connected to the other end of the connecting rod, and a right clamping plate is threadedly connected to one end of the third lead screw.

[0009] More preferably, the horizontal center line of the pressure plate is perpendicular to the vertical center line of the fixing frame, and the pressure plate and the vertical rod are connected by a sliding connection.

[0010] More preferably, the upper support rod and the lower support rod form a rotating structure through a vertical rod, and the rubber strip and the vertical rod are arranged in a parallel structure.

[0011] More preferably, the assembly assembly consists of two sets, and the two sets of assemblies are located on the outer wall of the left baffle and the outer wall of the right baffle, respectively, and the upper surfaces of the left limiting rod and the right limiting rod are on the same horizontal line.

[0012] More preferably, there are a total of six left and right limiting rods, and the left and right limiting rods are evenly distributed between the left and right baffles at equal intervals.

[0013] More preferably, the second lead screw and the left baffle are connected by a rotatable connection, and the third lead screw and the right baffle are connected by a rotatable connection.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, by rotating the first lead screw, the pressure plate slides downward and remains perpendicular to the fixing frame. When the fixing frame is attached to the cutting platform, the pressure plate can press down vertically and fit against the platform surface. Together with the lower surface of the fixing frame, the platform is clamped, facilitating quick fixation of the assembly components and further securing the entire device. Regardless of whether the edge of the cutting platform is flat or curved, during the process of pressing the two rubber strips against the side of the cutting platform, the upper and lower support rods rotate and unfold around the vertical rod as the center point. The rubber strips can fit tightly against the edge of the cutting platform, enhancing the fixing effect.

[0016] In this invention, six left and right limit rods are evenly distributed to support the steel when it is in use, and the gap in the middle is convenient to accommodate the cutting tool, avoiding direct contact between the tool and the cutting platform. During installation, the right limit rod can be pulled along the left limit rod according to the size of the cutting platform to further adjust the spacing of the assembly components at both ends, thus adapting to various sizes of cutting platforms.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a cutting auxiliary device that is easy to fix, including an assembly component 1. A left baffle 2 is welded to one side of the assembly component 1. A left limiting rod 3 is welded to the inner wall of the left baffle 2. A right limiting rod 4 is slidably connected inside the left limiting rod 3. A right baffle 5 is welded to one end of the right limiting rod 4. A clamping component 6 is installed between the left baffle 2 and the right baffle 5.

[0024] Assembly component 1 includes a fixing frame 101. A first lead screw 102 is rotatably connected inside the fixing frame 101. A pressure plate 103 is threadedly connected to the surface of the first lead screw 102. A vertical rod 104 is welded to the side of the fixing frame 101 near the first lead screw 102. An upper support rod 105 and a lower support rod 106 are rotatably connected to the surface of the vertical rod 104. A rubber strip 107 is rotatably connected to the other end of both the upper support rod 105 and the lower support rod 106.

[0025] In this embodiment, as Figure 1As shown, the clamping assembly 6 includes a left clamping plate 601. A second lead screw 602 is threadedly connected to the bottom of the left clamping plate 601. A connecting rod 603 is slidably connected to one end of the second lead screw 602. A third lead screw 604 is slidably connected to the other end of the connecting rod 603. A right clamping plate 605 is threadedly connected to one end of the third lead screw 604. It should be noted that the left clamping plate 601 is slidably connected to the left limiting rod 3, and the right clamping plate 605 is slidably connected to the right limiting rod 4. The second lead screw 602 and the third lead screw 604 are symmetrically distributed and connected by a connecting rod 603. The vertical section of the connecting rod 603 is set to a square. A knob is welded to one end of the second lead screw 602. When the second lead screw 602 rotates, it drives the third lead screw 604 to rotate in the same direction. The left clamping plate 601 and the right clamping plate 605 move closer to each other to clamp the steel.

[0026] In this embodiment, as Figure 3 and Figure 4 As shown, the horizontal center line of the pressure plate 103 is perpendicular to the vertical center line of the fixing frame 101, and the pressure plate 103 and the vertical rod 104 are connected by a sliding connection. It should be noted that when the pressure plate 103 slides down, it always remains perpendicular to the fixing frame 101. When the inner wall of the bottom of the fixing frame 101 is in contact with the lower surface of the cutting platform, the pressure plate 103 can be pressed down vertically to fit against the platform surface and clamp the platform together with the lower surface of the fixing frame 101, which facilitates quick fixing of the assembly component 1.

[0027] In this embodiment, as Figure 4 As shown, the upper support rod 105 and the lower support rod 106 form a rotating structure through the vertical rod 104, and the rubber strip 107 is parallel to the vertical rod 104. It should be noted that, regardless of whether the edge of the cutting platform is flat or curved, during the process of pressing the two rubber strips 107 against the side of the cutting platform, the upper support rod 105 and the lower support rod 106 rotate and unfold around the vertical rod 104 as the center point, so that the rubber strip 107 can fit tightly against the edge of the cutting platform, enhancing the fixing effect.

[0028] In this embodiment, as Figure 1 As shown, there are two sets of assembly components 1, and the two sets of components are located on the outer wall of the left baffle 2 and the outer wall of the right baffle 5, respectively. The upper surfaces of the left limit rod 3 and the right limit rod 4 are on the same horizontal line. It should be noted that the assembly components 1 at both ends are aligned with the two sides of the cutting platform, and the distance between the two sets of assembly components 1 can be adjusted according to the size of the cutting platform. The right limit rod 4 can be adjusted to slide along the left limit rod 3, and the distance between the left baffle 2 and the baffle can be adjusted.

[0029] In this embodiment, as Figure 1 and Figure 2As shown, there are a total of six left limit rods 3 and right limit rods 4, which are evenly distributed between the left baffle 2 and the right baffle 5 at equal intervals. It should be noted that the six left limit rods 3 and right limit rods 4 are evenly distributed to support the steel when it is being cut, and the gaps in the middle are convenient to accommodate the cutting tool, avoiding direct contact between the tool and the cutting platform.

[0030] In this embodiment, as Figure 1 and Figure 2 As shown, the second lead screw 602 is rotatably connected to the left baffle 2, and the third lead screw 604 is rotatably connected to the right baffle 5. It should be noted that while the left baffle 2 and the right baffle 5 support the end points of the second lead screw 602 and the third lead screw 604 respectively, they do not affect their rotational movement, ensuring that the second lead screw 602, the connecting rod 603 and the third lead screw 604 are always on the same horizontal line.

[0031] The method of use and advantages of this utility model: This easy-to-fix cutting auxiliary device operates as follows:

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, firstly, slide the right limiting rod 4 along the left limiting rod 3 to widen the gap between the left baffle 2 and the right baffle 5 until the assembly components 1 at both ends slightly exceed the edge of the platform. Align the rubber strips 107 at both ends with the edge of the cutting platform and press the left baffle 2 and the right baffle 5 inward. At this time, the rubber strips 107 begin to adhere to the edge of the cutting platform. Continue to press the left baffle 2 and the right baffle 5, and the upper support rod 105 and the lower support rod 106 begin to rotate and unfold around the vertical rod 104. As the upper support rod 105 and the lower support rod 106 unfold, the gap between the rubber strips 107 connecting the upper support rod 105 and the lower support rod 106 gradually widens until the outer edges of the upper support rod 105 and the lower support rod 106 are fully extended. The sides are in contact with the edge of the fixing frame 101. The rotation angle of the upper support rod 105 and the lower support rod 106 has reached its limit and cannot be further extended. At this time, the rubber strips 107 at both ends are in close contact with the edge of the cutting platform. Then, the first lead screw 102 is rotated. The first lead screw 102 is forward-driven, driving the pressure plate 103 to press down until the pressure plate 103 is in close contact with the upper surface of the platform. The inner wall of the lower surface of the fixing frame 101 is in close contact with the lower surface of the cutting platform. The upper and lower sides are clamped and fixed to the assembly component 1. At this time, the left baffle 2 and the right baffle 5 installed with the assembly component 1 are fixed to the upper surface of the cutting platform. The left clamping plate 601 and the right clamping plate 605 can help to clamp the steel.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
