Description

Technical Field

[0001] This utility model relates to the field of angle grinder technology, specifically a fixing bracket for an angle grinder used for cutting steel pipes. Background Technology

[0002] Angle grinders use a high-speed rotating cutting disc to quickly cut steel pipes, improving production efficiency and providing precise control suitable for scenarios requiring accurate cutting lengths or angles, meeting processing precision requirements. Flexible operation, angle grinders are small and lightweight, suitable for on-site operations or steel pipe cutting in complex environments, reducing costs. Compared to dedicated steel pipe cutting equipment, angle grinders are cheaper, and the cutting discs are easy to replace, resulting in low operating costs. They are adaptable to various materials and can cut steel pipes of different materials (such as carbon steel, stainless steel, galvanized pipes, etc.), with a wide range of applications. In the construction industry, they are used for steel pipe cutting in steel structures, pipe installation, and door and window manufacturing. In machinery manufacturing, they are used for steel pipe blanking or trimming in metal processing and equipment manufacturing. Repair and maintenance applications include steel pipe cutting needs in pipeline modification and equipment repair. Automotive manufacturing and repair applications include cutting exhaust pipes, vehicle frames, and other metal parts. Home DIY and small-scale projects are suitable for individual or small-scale steel pipe cutting needs. III. Working Principle: The core principle of angle grinder cutting steel pipes is to utilize the contact between the high-speed rotating cutting disc and the steel pipe, achieving material removal through friction and shearing force.

[0003] Angle grinders are driven by a motor, which transmits power to the cutting disc via a drive shaft, causing it to rotate at high speed (typically 10,000-30,000 rpm). During the cutting process, after the cutting disc contacts the steel pipe, the high-speed rotating disc generates intense friction and pressure on the pipe surface. Hard particles from the cutting disc (such as alumina or silicon carbide) continuously peel away material from the pipe during rotation, forming a kerf. As the disc continues to rotate, the kerf gradually deepens, eventually cutting the pipe. Cooling and Lubrication: A large amount of heat is generated during cutting, which may damage the cutting disc or the pipe surface. Therefore, water or cutting fluid is typically used for cooling and lubrication to extend tool life and improve cutting quality. Stress Analysis: During cutting, the angle grinder must maintain stable pressure to ensure the cutting disc cuts evenly into the pipe. Excessive pressure may cause the cutting disc to break; insufficient pressure will result in low cutting efficiency or an uneven cut. IV. Precautions: Safe Operation: Wear protective glasses, gloves, and a mask to avoid injury from flying debris. Ensure the cutting disc is securely installed to prevent it from falling off. Maintain a constant feed rate during cutting and avoid excessive force. Regularly inspect the angle grinder motor, bearings, and cutting disc to ensure they are undamaged. Clean the angle grinder promptly after use to prevent residue from affecting performance. By properly setting up and using the angle grinder, steel pipe cutting tasks can be completed efficiently and accurately, while reducing costs and adapting to various application scenarios.

[0004] Currently, angle grinders are often handled manually during operation. However, this requires multiple adjustments to the workpiece position. Manual hand-held operation increases workload and can lead to fatigue as cutting progresses, making it unsuitable for practical use. Summary of the Invention

[0005] The main purpose of this utility model is to solve the above-mentioned existing technical problems and provide a fixing bracket for an angle grinder for cutting steel pipes.

[0006] The specific solution of this utility model is: a fixed bracket for an angle grinder for cutting steel pipes, including a worktable, guide rods, a horizontal plate, an angle grinder body, and a mounting frame. A fixing plate is bolted to the top left side of the worktable. The fixing plate is an L-shaped structure, and guide rods are installed on the top surface of its horizontal section. There are two sets of guide rods, which are arranged on both sides of the top surface of the fixing plate. The guide rods are connected to the two ends of the horizontal plate by connecting pipes. A mounting frame is installed in the middle of the horizontal plate. The angle grinder body is installed inside the mounting frame. A handle is installed on the top side of the mounting frame.

[0007] According to the above technical solution, the angle grinder can move laterally by cooperating with the L-shaped fixing plate, guide rod and cross plate. Combined with the design of the mounting bracket and handle, the angle grinder can be stably clamped and the cutting position can be accurately adjusted, which improves the stability and operation convenience of steel pipe cutting.

[0008] Furthermore, clamping plates are installed on both sides of the top of the mounting frame. Two sets of clamping plates are arranged opposite each other. The clamping plates are U-shaped in shape. The front end of the clamping plates is in clamping contact with the angle grinder body, and the rear end is connected to the inside of the mounting frame through a spring rod. A support plate is installed at the bottom of the mounting frame. The support plate is connected to the angle grinder body through bolts on both sides and pre-drilled screw holes.

[0009] According to the above technical solution, the angle grinder body is elastically clamped by two sets of U-shaped clamping plates arranged opposite each other and spring rods. Combined with the fixation of the bottom support plate and bolts, the angle grinder can be quickly installed, self-adaptive clamping and vibration-proof stability are achieved, ensuring the stable position of the equipment during the cutting process.

[0010] Furthermore, a support column is installed on the top surface of the workbench away from the fixed plate. A movable frame is fitted around the outside of the support column. Adjustment holes are spaced at intervals on the outer side of the support column. Screw holes are opened on the corresponding side of the movable frame and the support column. An adjustment column is installed on the side of the movable frame facing the middle of the workbench. An upper auxiliary wheel is installed at the bottom of the extended end of the adjustment column. A lower auxiliary wheel is installed on the workbench directly below the upper auxiliary wheel. Two sets of lower auxiliary wheels are spaced apart.

[0011] According to the above technical solution, the height of the upper auxiliary wheel can be adjusted up and down by the cooperation of the support column, the movable frame and the adjustment hole. Combined with the two sets of lower auxiliary wheels set at intervals at the bottom of the workbench, adaptive clamping and stable support for steel pipes of different diameters can be achieved, ensuring that the position of the steel pipe is fixed and does not shift during cutting.

[0012] Furthermore, a top block is installed on the top of the support column, and a tension spring is installed between the top block and the movable frame.

[0013] According to the above technical solution, by setting a top block at the top of the support column and connecting the moving frame with a tension spring, the moving frame can be automatically tensioned by the elastic tension of the tension spring, so that the upper auxiliary wheel always fits in contact with the surface of the steel pipe, reducing the frequency of manual adjustment and improving the stability and convenience when clamping steel pipes of different diameters.

[0014] Furthermore, the side of the extended end of the adjusting column is provided with a mounting hole. The mounting hole is generally semi-circular in structure. A connecting plate is installed on the outside of the mounting hole. The connecting plate is pre-drilled with a semi-circular hole. A marker pen is installed inside the mounting hole.

[0015] According to the above technical solution, by opening a semi-circular mounting hole at the extension end of the adjusting column and fixing a marker pen with a connecting plate having a semi-circular hole, the cutting position can be marked along the surface of the steel pipe with the marker pen before cutting, realizing the integration of positioning and cutting operations, and improving processing efficiency and accuracy.

[0016] Furthermore, the bolts in the connecting plate have a reserved length.

[0017] According to the above technical solution, by pre-reserving the bolt length in the connecting plate, the marker pen can be quickly installed and removed without disassembling the bolt. At the same time, it ensures that the connecting plate and the mounting hole of the adjusting column are tightly fitted when the bolt is tightened, taking into account both the convenience of marker pen installation and the reliability of fixing.

[0018] Furthermore, a protective pad is attached to the inside of the mounting hole with an adhesive backing, and the protective pad is an integral rubber pad structure.

[0019] According to the above technical solution, by attaching a rubber protective pad with adhesive backing, the friction between the marker and the mounting hole can be buffered, preventing wear on the marker shell. At the same time, the elasticity of the rubber can be used to improve the stability of the marker during installation and extend its service life.

[0020] Compared with the prior art, this utility model has the following advantages: 1. After the angle grinder body is installed in the mounting frame, in the working state, the angle grinder body and the horizontal plate can be moved up and down under the limit of the guide rod by manually operating the handle, which is more convenient for processing the workpiece and more in line with actual use. 2. By placing the steel pipe into the lower auxiliary wheel and sliding the moving frame and support column up and down until the upper auxiliary wheel abuts against the upper circumference of the steel pipe, adjusting bolts are screwed into the holes of the moving frame and support column. Through the cooperation of the upper and lower auxiliary wheels, the steel pipe is clamped while allowing the steel to move freely. The tube rotates around its own axis as a reference point, cooperating with the angle grinder body for cutting. The adjustable frame accommodates various sizes of steel pipes, enhancing the overall practicality of the device. 2. By placing a marker pen inside the mounting hole and connecting the connecting plate to the end of the adjusting column with bolts, the marker pen is positioned so that the bottom of the marker pen's core abuts against the outer circumference of the steel pipe below. This allows for easy marking of the steel pipe while it rotates. The protective pad protects the marker pen and provides friction for installation, making its use more stable.

[0026] See Figure 1-4 This embodiment is a fixing bracket for an angle grinder used for cutting steel pipes, including a worktable 1, a guide rod 2, a cross plate 3, an angle grinder body 4, and a mounting bracket 5; as shown Figures 1-2As shown, a fixing plate 11 is bolted to the top left side of the workbench 1. The fixing plate 11 has an L-shaped structure. A guide rod 2 is installed on the top surface of its horizontal section. There are two sets of guide rods 2, which are arranged on both sides of the top surface of the fixing plate 11. The guide rods 2 are connected to the two ends of the horizontal plate 3 by connecting tubes. A mounting frame 5 is installed in the middle of the horizontal plate 3. The angle grinder body 4 is installed inside the mounting frame 5. A handle 51 is installed on the top side of the mounting frame 5. When working, after the angle grinder body 4 is installed in the mounting frame 5, the handle 51 can be manually operated to move the angle grinder body 4 and the horizontal plate 3 up and down under the limit of the guide rod 2, which makes it more convenient to process the workpiece and is more in line with actual use.

[0027] Furthermore, such as Figures 1-2 As shown, clamping plates 52 are installed on both sides of the top of the mounting frame 5. There are two sets of clamping plates 52 arranged opposite each other. The clamping plates 52 are U-shaped in general. Their front ends are clamped and contacted with the angle grinder body 4, and their rear ends are connected to the inside of the mounting frame 5 through spring rods. A support plate 53 is installed at the bottom of the mounting frame 5. The support plate 53 is connected to the angle grinder body 4 through bolts on both sides.

[0028] Furthermore, such as Figure 1 , Figure 3 As shown, a support column 6 is installed on the top surface of the workbench 1 away from the fixed plate 11. A movable frame 61 is fitted around the support column 6. Adjustment holes are spaced at intervals on the outer side of the support column 6. Screw holes are opened on the corresponding surface of the movable frame 61 and the support column 6. An adjustment column 62 is installed on the side of the movable frame 61 facing the middle of the workbench 1. An upper auxiliary wheel 65 is installed at the bottom of the extended end of the adjustment column 62. A lower auxiliary wheel 66 is installed on the workbench 1 directly below the upper auxiliary wheel 65. Two sets of lower auxiliary wheels 66 are spaced apart. During operation, the... The steel pipe is placed into the lower auxiliary wheel 66, and the moving frame 61 and the support column 6 are slid up and down until the upper auxiliary wheel 65 abuts against the upper circumferential surface of the steel pipe. Then, the adjusting bolts are screwed into the holes of the moving frame 61 and the support column 6. Through the cooperation of the upper auxiliary wheel 65 and the lower auxiliary wheel 66, the steel pipe is clamped while allowing it to rotate around its own axis as a reference point for cutting in conjunction with the angle grinder body 4. The moving frame 61 can be adjusted to accommodate steel pipes of various sizes, improving the practicality of the overall device.

[0029] Furthermore, such as Figure 3 As shown, a top block 63 is installed on the top of the support column 6, and a tension spring 64 is installed between the top block 63 and the movable frame 61.

[0030] Furthermore, such as Figures 3-4As shown, the side of the extended end of the adjusting column 62 is provided with a mounting hole 67. The mounting hole 67 is a semi-circular structure. A connecting plate 68 is installed on the outside of the mounting hole 67. The connecting plate 68 has a semi-circular hole pre-drilled. A marker pen 7 is installed inside the mounting hole 67. During operation, by placing the marker pen 7 into the mounting hole 67, the connecting plate 68 is connected to the end of the adjusting column 62 by bolts to limit the position of the marker pen 7, so that the bottom of the marker pen 7 abuts against the outer circumference of the steel pipe below. While rotating the steel pipe, it is convenient to mark the steel pipe with the marker pen 7.

[0031] Furthermore, such as Figure 4 As shown, the bolts in the connecting plate 68 are pre-reserved in order to allow the marker 7 to be released from its limit and its vertical position to be adjusted by loosening the bolts during operation, without having to completely remove the connecting plate 68.

[0032] Furthermore, such as Figure 4 As shown, a protective pad 69 is attached to the inside of the mounting hole 67 with adhesive backing. The protective pad 69 is a rubber pad structure, which is intended to protect the marker 7 while providing friction for the installation of the marker 7, thereby making the use of the marker 7 more stable.

[0033] The working principle of this embodiment is as follows: After the angle grinder body 4 is installed in the mounting bracket 5, in the working state, the angle grinder body 4 and the horizontal plate 3 can be moved up and down under the limit of the guide rod 2 by manually operating the handle 51, which makes it more convenient to process the workpiece and more in line with actual use. By placing the steel pipe into the lower auxiliary wheel 66, and by sliding the moving frame 61 and the support column 6 up and down until the upper auxiliary wheel 65 abuts against the upper circumferential surface of the steel pipe, the adjusting bolt is screwed into the hole of the moving frame 61 and the support column 6. The auxiliary wheel 66, when used in conjunction with the steel pipe, allows the steel pipe to rotate around its own axis while clamping it, enabling it to cut in conjunction with the angle grinder body 4. The adjustable frame 61 can accommodate steel pipes of various sizes, improving the overall practicality of the device. By placing the marker pen 7 inside the mounting hole 67 and connecting the connecting plate 68 to the end of the adjusting column 62 with bolts, the marker pen 7 is limited, causing the bottom of the marker pen 7 to abut against the outer circumference of the steel pipe below. This allows for easy marking of the steel pipe with the marker pen 7 while it rotates.
