Description

Technical Field

[0001] This utility model relates to the field of cutting equipment, specifically a positioning and cutting device that can be used for steel. Background Technology

[0002] Steel is an indispensable material in modern industry, possessing advantages such as high strength, good toughness, plasticity, and corrosion resistance. It is widely used in numerous fields, including construction, machinery manufacturing, and the automotive industry. In construction, it is used to build bridges, high-rise buildings, and railway tracks; in machinery manufacturing, it is used to manufacture various mechanical parts and equipment frames; and in the automotive industry, it is used for body structures and engine components.

[0003] Welding is a common method for joining steel materials. It allows steel of different shapes and sizes to be joined together to form various complex structures and products. In some cases, to meet specific design requirements, welding methods, or load-bearing needs, the ends of the steel materials are beveled. For example, in steel structure construction, the connection of certain components may require beveled ends to achieve better load-bearing performance and aesthetics; in mechanical manufacturing, the connection of some shaft parts with other components may require beveled ends to ensure fitting accuracy and assembly process.

[0004] There are many types of equipment used for steel cutting, such as handheld cutting machines. Because handheld cutting machines are small and lightweight, they are easy for operators to carry and move, allowing for flexible use in different work locations, and are especially suitable for scenarios with limited space or where on-site cutting is required. In addition, handheld cutting machines allow for easy adjustment of the cutting angle and position.

[0005] When using a handheld cutting machine to bevel steel, auxiliary tools and markers are needed to control the handheld cutting machine to move along the preset tilt angle.

[0006] For example, when using a right-angled triangle as an auxiliary tool, align one right-angled side of the triangle with the edge of the steel, and use the other right-angled side as a guide for the cutting machine. Pushing the cutting machine along the hypotenuse of the triangle achieves a bevel cut. During the cutting process, one hand needs to hold the cutting machine while the other supports the triangle, requiring a high degree of hand stability from the operator. Because handheld cutting machines vibrate during operation, the triangle can easily shift or wobble, affecting the accuracy of the cutting angle. Furthermore, it's difficult for the operator to consistently push the cutting machine along the hypotenuse of the triangle, potentially causing deviations in the cutting trajectory.

[0007] Another method involves measuring and marking a predetermined tilt angle line on the steel surface using a ruler or protractor. During cutting, the cutting blade of the cutting machine is aligned with the marked line, striving to keep the blade and the marked line coincident to control the cutting angle. However, relying solely on the marked line to control the cutting angle lacks effective physical support and guidance. During cutting, the cutting machine is easily affected by unevenness of the steel surface or cutting resistance, causing it to deviate from the marked line, especially when cutting thick or hard steel. Utility Model Content

[0029] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0030] Example 1

[0031] like Figure 1 As shown, when using a handheld cutting machine to bevel steel, the handheld cutting machine is controlled to move along a predetermined tilt direction to change its deviation from the predetermined track, while reducing the impact on the original function of the handheld cutting machine. This embodiment provides an auxiliary tool for the handheld cutting machine, which is matched with an existing handheld cutting machine to form a new steel cutting device. Specifically, the steel cutting device includes a handheld cutting machine (hereinafter referred to as the handheld cutting machine body 1) and an auxiliary support. The auxiliary support can be adjusted according to needs, thereby facilitating the adjustment of the tilt angle of the handheld cutting machine body 1, and providing support for controlling the handheld cutting machine body 1 to move along the predetermined tilt direction.

[0032] Before introducing the auxiliary support, let's briefly introduce the publicly available handheld cutting machine body 1. It includes a motor, handle, cutting disc clamp, cutting disc, protective cover, and machine body. The motor is the power source of the cutting machine, generally a series-wound motor, which converts electrical energy into mechanical energy to drive the cutting disc to rotate at high speed for cutting operations. It features high power, high speed, and high torque to meet the cutting needs of steel of different materials and thicknesses. The handle is the part that the operator holds, generally designed ergonomically, and is mostly made of rubber or plastic, providing good anti-slip properties and comfort, reducing hand fatigue during prolonged operation. Some handles also integrate a power switch for convenient operation. The cutting disc clamp is used to fix the cutting disc, usually composed of nuts, washers, and bushings. It ensures the stability and concentricity of the cutting disc during high-speed rotation, preventing the cutting disc from shaking or falling off during cutting, ensuring cutting safety and accuracy. The cutting disc is the part that directly performs the cutting, generally made of abrasives such as diamond or silicon carbide, and fixed together with resin or ceramic binders. Depending on the material being cut, the material, grit size, and thickness of the cutting blade vary. For example, cutting blades for steel are typically thinner and have a finer grit to improve cutting efficiency and quality. A protective cover is installed around the cutting blade to protect the operator from flying debris, sparks, and fragments from broken blades generated during the cutting process. The protective cover is generally made of high-strength plastic or metal, providing good impact resistance. The machine body is the main structure of the cutting machine, usually made of metal or high-strength plastic, and houses and secures components such as the motor, power switch, and handle, while also bearing the various forces exerted during the cutting process. The machine body should be designed with sufficient strength and rigidity to ensure the stability and reliability of the cutting machine during operation.

[0033] like Figure 1 , Figure 3 As shown, in order to adjust the state of the handheld cutting machine body 1 while supporting it, the auxiliary support includes an adjustment mechanism 4, a support mechanism 3, and a base 2. The adjustment mechanism 4 is hinged below the handheld cutting machine body 1. The support mechanism 3 is located below the adjustment mechanism 4, and its position can be adjusted by changing the state of the adjustment mechanism 4. The base 2 is located below the support mechanism 3 and supports the steel, thus facilitating the handheld cutting machine body 1 to adjust its tilt angle and lower to perform beveling on the steel.

[0034] like Figure 2 , Figure 6As shown, in order to hinge the adjustment mechanism 4 to the lower part of the handheld cutter body 1, an ear plate 11 is provided at the lower end of the handheld cutter body 1. The adjustment mechanism 4 includes a connecting plate 44. A connecting bolt 41 is provided on the top of the connecting plate 44 through a bearing. Two nuts are threaded on the threaded part of the connecting bolt 41. Therefore, when it is necessary to use the auxiliary bracket to support the handheld cutter body 1 to achieve the oblique cutting of steel, the end of the connecting bolt 41 is set through the ear plate 11, and the two nuts are distributed on both sides of the ear plate 11. With the cooperation of the two nuts, the ear plate 11 is stably installed on the side of the connecting plate 44. Under the condition of stable connection between the auxiliary bracket and the handheld cutter body 1, it provides convenience for controlling the rotation of the handheld cutter body 1 around the axis to achieve steel cutting.

[0035] like Figure 5 , Figure 6 As shown, with the handheld cutting machine body 1 stably connected to the auxiliary support, in order to adjust the tilt angle of the handheld cutting machine body 1, the support mechanism 3 includes a connecting frame 32. The connecting frame 32 is configured as a U-shaped structure, and the cylinder at the bottom of the connecting plate 44 is located inside the connecting frame 32. A fastening bolt 42, which passes through the bottom cylinder of the connecting plate 44, is also installed through the connecting frame 32, and a nut is threaded onto the end of the fastening bolt 42. Under the action of the nut and the fastening bolt 42, the end of the connecting frame 32 is forced to deform, causing the connecting plate 44 to be stably placed relative to the connecting frame 32. This allows the handheld cutting machine body 1 to be stably positioned at a certain tilt angle, and provides convenience for adjusting the tilt angle of the handheld cutting machine body 1 by removing the restriction of the connecting plate 44 as needed.

[0036] like Figure 5 , Figure 6 As shown, in order to adjust the tilt angle of the handheld cutting machine body 1 more accurately, a scale 33 is provided at the end of the connecting frame 32, and a pointer 43 is provided at the end of the connecting plate 44. Therefore, the pointer 43 and the scale 33 can be used to provide a reference for rotating the handheld cutting machine body 1.

[0037] like Figure 5 As shown, after the tilt angle of the handheld cutting machine body 1 is adjusted, in order to facilitate the handheld cutting machine body 1 to descend and complete the cutting of steel, the support mechanism 3 includes a horizontal tube 35, a vertical tube 31, etc. The connecting frame 32 is installed on the horizontal tube 35, the horizontal tube 35 is lifted and sleeved on the vertical tube 31, and the vertical tube 31 is installed on the base 2. Therefore, with the connecting frame 32 stably installed, it is easy to control the handheld cutting machine body 1 to descend along the height of the vertical tube 31 and to cut the steel pipe during the descent.

[0038] like Figure 5As shown, in order to connect the connecting frame 32 and the horizontal tube 35, a first sleeve 34 is fixedly installed at the end of the connecting frame 32. A bolt is threaded through the side wall of the first sleeve 34. The horizontal tube 35 is installed through the first sleeve 34, and the end of the bolt is pressed against the horizontal tube 35. Therefore, it is convenient to position the handheld cutting machine body 1 directly above the steel to be cut by adjusting the position of the connecting frame 32.

[0039] like Figure 5 As shown, in order to achieve a stable connection between the horizontal tube 35 and the vertical tube 31, a second sleeve 36 is fixedly installed at the end of the horizontal tube 35, and the vertical tube 31 is installed through the second sleeve 36. Therefore, under the action of the gravity of the handheld cutting machine body 1 and the external thrust, the handheld cutting machine body 1 can be controlled to descend along the vertical tube 31 to achieve the cutting of steel.

[0040] like Figure 5 As shown, if you want to control the handheld cutting machine body 1 to be stably positioned at a certain height, a bolt can be threaded through the side wall of the second sleeve 36. The end of the bolt is set against the side wall of the vertical tube 31, which can brake the horizontal tube 35 and the vertical tube 31, so that the handheld cutting machine body 1 is placed stably.

[0041] like Figure 4 , Figure 5 As shown, in order to make the vertical tube 31 stably installed on the base 2, the base 2 includes a bottom frame 21 and an end post 23. The end post 23 is vertically set at the end corner above the bottom frame 21. The bottom of the vertical tube 31 is attached to the bottom frame 21, and the end post 23 is inserted into the vertical tube 31. For example, the end post 23 and the vertical tube 31 are connected by bolts. In addition, the cutting blade of the handheld cutting machine body 1 is offset from the bottom frame 21.

[0042] Example 2

[0043] like Figure 4 As shown, based on Embodiment 1, in order to facilitate the movement of steel on the base 2 to complete the cutting process, the base 2 also includes multiple rollers 22. The multiple rollers 22 are arranged in parallel on the inner side of the base frame 21, and the top of the rollers 22 is set higher than the upper side of the base frame 21. Therefore, the resistance to the movement of steel is reduced by the rotation of the rollers 22.

[0044] like Figure 4 As shown, a vertical rod 24 is fixedly installed at the end of the base frame 21, and a pressure rod 25 is installed above the base frame 21. One end of the pressure rod 25 is fitted onto the vertical rod 24. After adjusting the position of the steel, the worker can press down on the end of the pressure rod 25 away from the vertical rod 24, thereby pressing the steel against the base 2 and making the steel stably placed on the base 2, which facilitates the cutting of the steel. An arc-shaped groove 26 can also be provided on the lower side of the pressure rod 25 to accommodate round steel.

[0045] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
