Description
Technical Field
[0001] This utility model relates to the technical field of weld point grinding equipment, specifically a device for grinding weld points on steel structures. Background Technology
[0002] In modern industrial production, steel structures, with their high strength, good toughness, and convenient construction, are widely used in many fields such as construction, bridges, and machinery manufacturing. Steel structures employ various connection methods, with welding being the most common. Welding ensures the integrity and stability of the structure. However, welding inevitably produces weld slag, burrs, and uneven surfaces at the weld points. These defects not only affect the appearance of the steel structure but may also reduce its safety and durability over long-term use due to stress concentration. Grinding is necessary, but existing grinding equipment requires manual operation. The force generated when the grinding wheel contacts the surface of the steel structure causes the wheel to deviate, resulting in poor stability and low grinding efficiency. Furthermore, weld slag and burrs may splatter during grinding, potentially injuring operators. Therefore, a grinding device for steel structure weld points is needed to address these issues.
[0003] An existing steel structure weld point grinding device suffers from several drawbacks during operation. The grinding wheel deflects due to the force generated when it contacts the steel structure, making it difficult to grind quickly and accurately. This results in low efficiency, an inability to adapt to the grinding needs of steel structures of different sizes, and a lack of grinding protection. Therefore, there is an urgent need for a steel structure weld point grinding device. Utility Model Content
[0004] Based on this, the purpose of this utility model is to provide a steel structure weld point grinding device to solve the problems of existing steel structure weld point grinding devices, where the grinding wheel deviates due to the force generated when the grinding wheel contacts the steel structure during the grinding process, making it impossible to grind quickly and accurately, resulting in low efficiency, and also failing to adapt to the grinding needs of steel structure components of different sizes and failing to provide grinding protection.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel structure weld point grinding device, comprising a steel structural component, wherein the side wall of the steel structural component has a joint, a grinding machine body is mounted on the outer wall of the steel structural component, a limit hole is formed on the side wall of the grinding machine body, an adjusting plate is mounted on the outer wall of the grinding machine body, a limit rod is mounted on the side wall of the adjusting plate, a limit spring is mounted on the outer wall of the limit rod, a limit roller is mounted on the bottom of the adjusting plate, a locking block is mounted on both outer walls of the grinding machine body, a top spring is mounted on the inner wall of the locking block, a locking rod is mounted on the outer wall of the top spring, a protective sleeve is mounted on the outer wall of the locking rod, a power motor is mounted on the top of the grinding machine body, a grinding wheel is mounted on the bottom of the power motor, and a push rod is mounted on the top of the grinding machine body.
[0006] Preferably, the limiting holes are evenly distributed around the central axis of the grinding machine body, and the adjusting plate is movably connected to the grinding machine body.
[0007] Preferably, the limiting rod forms a telescopic structure with the adjusting plate through a limiting spring, and the limiting rod is engaged with the limiting hole.
[0008] Preferably, the limiting rollers are symmetrically arranged around the central axis of the grinding machine body, and the limiting rollers are in close contact with the side wall of the steel structure.
[0009] Preferably, the locking blocks are symmetrically arranged around the central axis of the grinding machine body, and the locking rod forms a telescopic structure with the locking blocks through a top spring.
[0010] Preferably, the protective sleeve is sleeved with the locking block, and the locking rod is engaged with the protective sleeve.
[0011] Preferably, the protective sleeve is C-shaped, and the grinding wheel is tightly fitted to the top of the steel structure.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model, through the setting of limiting holes, adjusting plates, limiting rods, limiting springs, and limiting rollers, allows for the adjustment of the limiting rods on both sides to be pulled outward according to the grinding requirements of steel structural components of different sizes. Then, the adjusting plate is slid to the appropriate position, and the limiting rods are released. The limiting rods are then pressed inward by the elastic force of the limiting springs, so that the limiting rods are engaged and fixed with the limiting holes. At this time, the limiting rollers are in close contact with the side wall of the steel structural components. During grinding, the setting of the limiting rollers can not only ensure that the main body of the grinding machine cannot shift laterally, improving the stability of the grinding process, but also adapt to the grinding requirements of steel structural components of different sizes, making it more versatile.
[0014] 2. This utility model uses a locking block, a top spring, a locking rod, and a protective sleeve to press the locking rod inward, and then the protective sleeve is fitted onto the locking block. At this time, the locking rod is pushed out by the elastic force of the top spring, so that the locking rod and the protective sleeve are locked and fixed. The protective sleeve can prevent welding slag and burr debris from flying during the grinding process and causing injury to the operator, thus increasing the safety of the grinding process.

An adjusting plate 5 is mounted on the outer wall of the grinding machine body 3. A limiting rod 6 is mounted on the side wall of the adjusting plate 5. A limiting spring 7 is mounted on the outer wall of the limiting rod 6. A limiting roller 8 is mounted on the bottom of the adjusting plate 5. The limiting holes 4 are evenly distributed around the central axis of the grinding machine body 3. The adjusting plate 5 is movably connected to the grinding machine body 3. The limiting rod 6 forms a telescopic structure with the adjusting plate 5 through the limiting spring 7. The limiting rod 6 is engaged with the limiting holes 4. The limiting roller 8 is positioned around the central axis of the grinding machine body 3. The design is symmetrically arranged, with the limiting rollers 8 tightly fitted to the side wall of the steel structure component 1. Through the limiting holes 4, adjusting plates 5, limiting rods 6, limiting springs 7, and limiting rollers 8, the limiting rods 6 on both sides are pulled outwards according to the grinding requirements of steel structure components 1 of different sizes. Then, the adjusting plate 5 is slid to the appropriate position, and the limiting rods 6 are released. The limiting rods 6 are then pressed inwards by the elastic force of the limiting springs 7, causing the limiting rods 6 to engage and fix with the limiting holes 4. At this time, the limiting rollers 8 are tightly fitted to the side wall of the steel structure component 1. During grinding, the setting of the limiting rollers 8 not only ensures that the grinding machine body 3 cannot shift laterally, improving the stability of the grinding process, but also adapts to the grinding requirements of steel structure components 1 of different sizes, making it more versatile.
[0024] Please see Figure 1-5 A steel structure weld point grinding device is described, comprising a grinding machine body 3 with locking blocks 9 installed on both outer walls of the body, a top spring 10 installed on the inner wall of the locking blocks 9, a locking rod 11 installed on the outer wall of the top spring 10, and a protective sleeve 12 installed on the outer wall of the locking rod 11. A power motor 13 is installed on the top of the grinding machine body 3, a grinding wheel 14 is installed at the bottom of the power motor 13, and a push rod 15 is installed on the top of the grinding machine body 3. The locking blocks 9 are symmetrically arranged around the central axis of the grinding machine body 3, and the locking rod 11 forms a telescopic structure with the locking blocks 9 via the top spring 10. The protective sleeve 12 and... The locking block 9 is fitted together, and the locking rod 11 is engaged with the protective sleeve 12. The protective sleeve 12 is C-shaped. The grinding wheel 14 is tightly fitted with the top of the steel structure 1. Through the locking block 9, the top spring 10, the locking rod 11 and the protective sleeve 12, the locking rod 11 is pressed inward.

The setting of the protective sleeve 12 can prevent the welding slag and burr debris from splashing during the grinding process and causing injury to the operator, thus increasing the safety of the grinding process.
[0025] Working Principle: In use, first move the device to the desired position. Then, according to the grinding requirements of steel structural components 1 of different sizes, pull the limiting rods 6 on both sides outwards. Next, slide the adjusting plate 5 to the appropriate position and release the limiting rods 6. The limiting rods 6 are then pressed inwards by the elastic force of the limiting spring 7, causing them to engage and fix with the limiting hole 4. At this time, the limiting roller 8 is tightly fitted against the side wall of the steel structural component 1. During grinding, the setting of the limiting roller 8 ensures that the main body 3 of the grinder cannot shift laterally, improving the stability of the grinding process, and also adapts to the grinding requirements of steel structural components 1 of different sizes.
