Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of steel plate cutting equipment, and concretely relates to a steel plate cutting platform. BACKGROUND

[0002] The gantry type numerical control cutting machine is an automatic equipment for cutting metal plates and profiles, and is widely applied in manufacturing industry, especially in metal processing, shipbuilding, engineering machinery, automobile manufacturing and other industries.

[0003] The main feature of the gantry type numerical control cutting machine is to adopt a gantry type structure, that is, to have a transverse door type frame, to slidably connect a flame cutting gun or a plasma cutting head on the frame, to set slide rails on both sides of the frame, and to set a cutting platform under the frame, wherein the cutting platform is assembled by a plurality of grid bars, the steel plate is placed flat on the grid bars, the frame is slid on the slide rails and cooperates with the flame cutting gun to slide on the frame, the cutting gun is freely moved on the X axis and the Y axis, the steel plate on the platform grid bars under the frame is conveniently cut in a large area, and the gantry type numerical control cutting machine has high automation and intelligence, can realize automatic cutting of complex patterns through programming control, and improves production efficiency and machining precision.

[0004] When the equipment is in cutting work, the steel plate needs to be placed on the platform, the platform supports the steel plate, and the cutting gun is convenient to move and cut above the steel plate. For example, the prior art "cutting table for gantry cutting machine" (publication number: CN109093299A) discloses a cutting platform suitable for a gantry cutting machine, a plurality of steel sheets are welded on the longitudinal beams of the cutting platform to form a clamping groove, and the grid bars are placed in the clamping groove to fix the grid bars. However, this method has the following problems:

[0005] It is difficult to disassemble: once the steel sheet is welded to the longitudinal beam, it is difficult to remove. If the steel sheet is deformed or rusted, it must be cut off using a special cutting tool when it needs to be removed and replaced, which is very inconvenient to operate. INVENTION CONTENTS

[0006] The utility model provides a steel plate cutting platform, which can solve the problem that the cutting platform in the prior art must be cut off using a cutting tool when the rusted or deformed steel sheet needs to be replaced, the replacement and removal steps are complex, the operation is very inconvenient, and maintenance and maintenance are not facilitated.

[0007] The application provides the following technical scheme: a steel plate cutting platform, comprising two steel frames and a plurality of grid bars horizontally arranged on the two steel frames;

[0008] The steel frame is also provided with a plurality of bottom plates, which are fixed to the steel frame by third screws. Each bottom plate is connected to a positioning strip by screws. The positioning strip includes an integrally formed horizontal section and a groove section. The horizontal section is fixedly connected to the bottom plate by first screws. The groove section has a downwardly facing notch. A plurality of clamping grooves are formed at equal intervals on one side of the groove section near the grid bars. One end of the grid bar is inserted into the clamping groove.

[0009] The positioning strip is also fixed with an L-shaped baffle. A through opening is formed transversely on the positioning strip from the groove section to the horizontal section. One end of the baffle extends from the groove section to the horizontal section through the through opening and is fixed to the bottom plate by second screws. The other end of the baffle is vertically erected at both ends of the grid bar.

[0010] Advantages:

[0011] 1. Easy replacement and maintenance of parts: A plurality of positioning strips are arranged on the steel frame and fixed to the bottom plate by first screws. When the positioning strip rusts or the clamping groove on the positioning strip deforms, it can be easily replaced. The notch of the groove section on the positioning strip faces downward, forming an arched space. The part of the grid bar inserted into the clamping groove is contained in the arched space, limiting the grid bar in the vertical direction and increasing the stability of the grid bar. The arched space also provides a transverse space for the L-shaped baffle, making it very convenient to install and remove the baffle on the bottom plate, which facilitates quick replacement of parts and maintenance of the equipment.

[0012] 2. Easy positioning of steel plates: One end of the L-shaped baffle is fixed to the bottom plate, and the other end is vertically erected at both ends of the grid bar, forming a stable limiting structure. When placing the steel plate, the side of the steel plate is against the L-shaped baffle, limiting and guiding the position of the steel plate, so that the steel plate can be more conveniently positioned above the grid bar, improving the precision of steel plate cutting processing.

[0013] 3. Flexibility and adjustability: The through opening on the positioning strip allows the position of the baffle to be adjusted. According to the different sizes and shapes of the processed materials, the baffle can be moved along the positioning strip and re-fixed to adapt to the processing needs of different sizes of steel plates.

[0014] Further, the positioning strip is also provided with a first notch, which is located directly above the third screw.

[0015] Advantages: The first notch allows the operator to more easily access the third screw, using a wrench or screwdriver for quick tightening or adjustment, without having to bypass other parts of the positioning strip, improving work efficiency and convenience.

[0016] Further, the positioning strip is also provided with a second notch, which is located directly above the second screw.

[0017] Beneficial effect: The second notch can avoid interference between the tool and the structure of the positioning strip, ensuring that the operator can quickly adjust the position of the baffle on the bottom plate, ensuring smooth operation, and improving the convenience of adjusting the baffle position.

[0018] Furthermore, a strip hole is provided on the baffle, and the second screw passes downward through the strip hole and fixes the baffle on the bottom plate.

[0019] Beneficial effect: The design of the strip hole enables the baffle to move along the length of the hole within a certain range, so that the position of the baffle can be fine-tuned within this range, thereby ensuring that steel plates of different sizes can be accurately limited, improving the cutting accuracy and quality of the product.

[0020] Furthermore, protrusions are provided at both ends of the grid bar, and the protrusions can be inserted into the notches of the groove section from the slots of the positioning bar.

[0021] Beneficial effect: The protrusions enable the bars to be fixed quickly and accurately on the positioning bars without complicated adjustments, which greatly simplifies the installation process and improves work efficiency. After the protrusions are inserted into the slots, a firm connection between the bars and the positioning bars is ensured. Even if the bars are subjected to vibration or impact during processing, they are not easily displaced, ensuring installation stability.

[0022] Furthermore, the shape above the grid bars is tooth-shaped.

[0023] Beneficial effects: The toothed structure can increase the friction on the surface of the bars, provide better grip, and prevent the steel plate from shifting and slipping during the cutting process. The toothed structure can also serve as a reference point for positioning or guiding, helping the operator to place or align the workpiece more accurately, thereby improving processing accuracy and efficiency. At the same time, the toothed structure can distribute the weight of the steel plate more evenly on the bars, reducing local pressure and preventing the bars from deformation or damage under heavy loads.
