Abstract
Description
Technical Field
[0001] This application relates to the field of steel structure technology, specifically a steel structure grinding device. Background Technology
[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are employed. As is well known, steel structures generally require grinding to a certain degree before production and installation; therefore, grinding equipment is an indispensable piece of equipment for the entire steel structure industry.
[0003] Chinese utility model patent CN221621752U discloses a steel structure grinding device, relating to the field of steel structure technology. The device includes a grinding table assembly, a worktable, and a grinding component. The grinding table assembly includes a processing box, a first transmission mechanism, a second transmission mechanism, a first motor, and a processing table. After grinding one surface, a second electric push rod is activated to move the pressure plate upwards. Then, the first motor is activated, driving the first transmission mechanism to rotate, which in turn causes the worm gear to rotate. The worm gear, meshing with the worm, then rotates the rotating rod and the processing table fixedly connected to the top of the rotating rod. The processing table causes the arc-shaped block to rotate within an annular groove, making the rotation smoother and more stable. This device can effectively adjust the steel structure body without manual rotation, making it convenient to operate. However, the above solution has the following drawbacks: while the grinding component uses the first and second transmission mechanisms to grind the steel structure, the grinding blades wear down over time, making installation and disassembly inconvenient and overall use difficult.
[0004] Therefore, this application provides a steel structure grinding device to solve the above problems. Utility Model Content
[0005] This application provides a steel structure grinding device, which aims to solve the problem mentioned in the background art that the existing steel structure grinding is carried out by setting a first transmission mechanism and a second transmission mechanism in conjunction with a grinding component, but the grinding blade will wear out after long-term use, making it inconvenient to install and disassemble, and making it inconvenient to use.
[0006] To achieve the above objectives, this application provides the following technical solution: a steel structure grinding device, including a base, a control switch is provided at the top of one side of the base, and a grinding mechanism is provided at the top of the base;
[0007] To address the problems of existing grinding mechanisms that use a combination of a first and second transmission mechanism with a grinding assembly to grind steel structures, where grinding blades wear down over time, making installation and disassembly inconvenient and hindering use, the proposed grinding mechanism includes guide rails fixedly connected to both sides of the top of a base. A slider is slidably connected to the outside of the guide rails. A linear motor is mounted on one side of the slider. A moving frame is fixedly connected to the top of the slider, and an electric actuator is fixedly connected to the bottom of the moving frame. A servo motor is fixedly connected to the output end of the electric actuator, and a mounting slot is fixedly connected to the output end of the servo motor. A mounting block is housed inside the mounting slot, and a grinding block is fixedly connected to the bottom of the mounting block. Pressing the fixing rod causes it to slide outside the limiting rod under pressure. This causes the servo motor 2 on the side of the fixed rod to compress the fixed rod, allowing it to enter the interior of the mounting block and insert the mounting block into the interior of the mounting slot. The fixed rod, subjected to the spring's rebound force, engages with the fixing slots on both sides of the mounting block, facilitating the installation and removal of the grinding block. A linear motor drives the slider to slide outside the guide rail, causing the slider to move the moving frame. An electric actuator pushes the servo motor 1 at the bottom to rise and fall, which in turn rotates the mounting slot. The mounting block fixed inside the mounting slot rotates the grinding block, allowing for grinding of the steel structure. This allows for convenient movement and grinding of the steel structure, and easy replacement of worn grinding blocks as needed. The operation is simple, quick, and convenient.
[0008] Preferably, to solve the problem of convenient installation and disassembly, the mounting block is inserted into the mounting groove block, the mounting block is provided with two sets of fixing rods inside, and the mounting groove block has fixing grooves on both sides that are adapted to the fixing rods. The fixing rods are inserted into the fixing grooves, the mounting block is inserted into the mounting groove block, and the fixing rods are inserted into the mounting groove block, which can facilitate installation and disassembly and make it convenient to use.
[0009] Preferably, to address the issue of convenient operation of the fixing rod, a limiting rod is fixedly connected inside the mounting block. Two sets of fixing rods are disposed outside the limiting rods, and the fixing rods are slidably connected to the limiting rods. A spring is fixedly connected to one side of the two sets of fixing rods inside the mounting block. The fixing rods slide outside the limiting rods. The limiting rods improve the stability of the moving fixing rods. When the fixing rods compress the springs on the side, the springs' rebound force allows the fixing rods to easily return to their original shape, making them convenient to use.
[0010] Preferably, to solve the problem of convenient fixing and rotation of the steel structure, a second servo motor is fixedly connected to one side of the base. The output end of the second servo motor extends to one side of the base and is fixedly connected to a rotating block. An operating frame is fixedly connected to the side of the rotating block. A dual-axis motor is fixedly connected inside the operating frame. A threaded rod is fixedly connected to the output end of the dual-axis motor. A moving block is provided outside the threaded rod. A fixed clamping block is fixedly connected to one side of the moving block. The dual-axis motor drives the two sets of threaded rods to rotate inside the operating frame. The threaded rods are threadedly connected to the externally provided moving blocks, so that the moving blocks are subjected to force and move in opposite directions inside the operating frame. The moving blocks drive the fixed clamping blocks to clamp and fix the steel structure. The second servo motor drives the rotating block to rotate, and the rotating block drives the operating frame to rotate, so that the steel structure fixed by the fixed clamping blocks can rotate. This facilitates multi-faceted grinding operations, which are simple, quick, and easy to use.
[0011] Preferably, in order to solve the problem of easy movement of the movable block, the threaded rod is rotatably connected to the operating frame, the threaded rod is threadedly connected to the movable block, the movable block is disposed inside the operating frame, the movable block is slidably connected to the operating frame, the threaded rod is rotatably connected to the operating frame, the two sets of threaded rods have opposite threads on their outer surfaces, and the threaded rods are threadedly connected to the movable block, so that the movable block slides inside the operating frame under force, thus facilitating use.
[0012] Preferably, in order to solve the problem of clamping and fixing stability, the two sets of fixing blocks are symmetrically arranged, the two sets of fixing blocks are fixed to the moving block by bolts, and friction blocks are fixedly connected to opposite sides of the two sets of fixing blocks. The symmetrical arrangement of the fixing blocks facilitates the clamping and fixing of the steel structure, and the friction is increased by the friction blocks on the side of the fixing blocks, making it convenient to use.
[0013] This grinding mechanism presses down on a fixed rod, causing it to slide outside a limiting rod. This compresses a servo motor on the side of the fixed rod, allowing it to enter the mounting block and insert into the mounting groove. The fixed rod then engages with the mounting grooves on both sides of the mounting block due to spring rebound, facilitating easy installation and removal of the grinding block. A linear motor drives a slider to slide outside a guide rail, moving the movable frame. An electric actuator pushes a servo motor at the bottom to raise and lower the frame, which in turn rotates the mounting groove. The mounting block inside the groove rotates the grinding block, which then grinds the steel structure. This mechanism allows for easy movement and grinding of the steel structure, and facilitates easy replacement of worn grinding blocks as needed. Operation is simple, quick, and convenient.
[0014] This grinding mechanism uses a dual-axis motor to drive two sets of threaded rods to rotate inside the operating frame. The threaded rods are threadedly connected to externally mounted moving blocks, allowing the moving blocks to move in opposite directions within the operating frame. The moving blocks then drive the fixed clamping blocks to clamp and fix the steel structure. A servo motor drives a rotating block to rotate, which in turn drives the operating frame to rotate. This allows the steel structure fixed by the fixed clamping blocks to rotate, facilitating multi-faceted grinding operations. The mechanism is simple, quick, and easy to use.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0022] Example 1
[0023] This embodiment provides a steel structure grinding device, such as Figure 1-4 As shown, the steel structure grinding device includes a base 1, a control switch 2 is provided on the top side of the base 1, and a grinding mechanism 3 is provided on the top of the base 1.
[0024] The grinding mechanism 3 allows for easy movement and grinding of the steel structure, and the worn grinding blocks 39 can be easily replaced according to usage needs. The operation is simple, quick, and convenient.
[0025] Specifically, the grinding mechanism 3 includes guide rails 31 fixedly connected to both sides of the top of the base 1. A slider 32 is slidably connected to the outside of the guide rails 31. A linear motor 33 is provided on one side of the slider 32. A moving frame 34 is fixedly connected to the top of the slider 32. An electric push rod 35 is fixedly connected to the bottom of the moving frame 34. A servo motor 36 is fixedly connected to the output end of the electric push rod 35. A mounting slot 37 is fixedly connected to the output end of the servo motor 36. A mounting block 38 is provided inside the mounting slot 37. A grinding block 39 is fixedly connected to the bottom of the mounting block 38.
[0026] In use, pressing the fixing rod 40 causes it to slide outside the limiting rod 42 under force, thereby compressing the servo motor 44 on the side and allowing the fixing rod 40 to enter the mounting block 38. The mounting block 38 is then inserted into the mounting slot 37. The fixing rod 40 is subjected to the rebound force of the spring 43, allowing it to engage with the fixing slots 41 on both sides of the mounting slot 37. This facilitates the installation and removal of the grinding block 39. The linear motor 33 drives the slider 32 to slide outside the guide rail 31, which in turn moves the moving frame 34. The electric push rod 35 pushes the servo motor 36 at the bottom to rise and fall, which in turn drives the mounting slot 37 to rotate. The mounting block 38 fixed inside the mounting slot 37 then drives the grinding block 39 to rotate, allowing the grinding block 39 to grind the steel structure. This allows for easy movement and grinding of the steel structure, and the grinding block 39 can be easily replaced as needed. The operation is simple, quick, and convenient.
[0027] Furthermore, the mounting block 38 is inserted into the mounting groove block 37. The mounting block 38 has two sets of fixing rods 40 inside. The mounting groove block 37 has fixing grooves 41 on both sides that are adapted to the fixing rods 40. The fixing rods 40 are inserted into the fixing grooves 41, the mounting block 38 is inserted into the mounting groove block 37, and the fixing rods 40 are inserted into the fixing grooves 41. This allows for easy installation and disassembly, making it convenient to use.
[0028] Furthermore, the mounting block 38 is internally fixedly connected to a limiting rod 42, and two sets of fixing rods 40 are set outside the limiting rod 42, with the fixing rods 40 and the limiting rod 42 slidably connected. The two sets of fixing rods 40 are fixedly connected to a spring 43 on one side inside the mounting block 38. The fixing rods 40 slide outside the limiting rod 42. The limiting rod 42 can improve the stability of the movement of the fixing rods 40. When the fixing rods 40 compress the springs 43 on the side, the springs 43 can rebound force to easily restore the fixing rods 40 to their original shape, making it convenient to use.
[0029] Example 2
[0030] Unlike Embodiment 1, in order to solve the problem of easy fixing and rotation of the steel structure, a servo motor 44 is fixedly connected to one side of the base 1. The output end of the servo motor 44 extends to the side of the base 1 and is fixedly connected to a rotating block 45. An operating frame 46 is fixedly connected to the side of the rotating block 45. A dual-axis motor 47 is fixedly connected inside the operating frame 46. A threaded rod 48 is fixedly connected to the output end of the dual-axis motor 47. A moving block 49 is provided outside the threaded rod 48. A fixing clamp 50 is fixedly connected to one side of the moving block 49.
[0031] In use, the dual-axis motor 47 drives two sets of threaded rods 48 to rotate inside the operating frame 46. The threaded rods 48 are threadedly connected to the externally installed moving blocks 49, so that the moving blocks 49 are subjected to force and move in opposite directions inside the operating frame 46. The moving blocks 49 drive the fixed clamping blocks 50 to clamp and fix the steel structure. The servo motor 44 drives the rotating block 45 to rotate, and the rotating block 45 drives the operating frame 46 to rotate, so that the steel structure fixed by the fixed clamping blocks 50 can rotate, which facilitates multi-face grinding operations. The operation is simple and quick, and it is easy to use.
[0032] Specifically, the threaded rod 48 is rotatably connected to the operating frame 46, and the threaded rod 48 is threadedly connected to the movable block 49. The movable block 49 is located inside the operating frame 46 and is slidably connected to the operating frame 46. The threaded rod 48 is rotatably connected to the operating frame 46. The two sets of threaded rods 48 have opposite threads on their outer surfaces. The threaded rod 48 is threadedly connected to the movable block 49, so that the movable block 49 slides inside the operating frame 46 under force, which facilitates use.
[0033] Furthermore, the two sets of fixing clamps 50 are symmetrically arranged, and the two sets of fixing clamps 50 are fixed to the moving block 49 by bolts. Friction blocks 51 are fixedly connected to the opposite side of the two sets of fixing clamps 50. The symmetrical arrangement of the fixing clamps 50 facilitates the clamping and fixing of the steel structure, and the friction force is increased by the friction blocks 51 provided on the side of the fixing clamps 50, making it convenient to use.
[0034] It should be noted that the control switch 2, linear motor 33, electric actuator 35, servo motor 1 36, servo motor 2 44, and dual-axis motor 47 are existing devices. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
[0035] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
