Description

Technical Field

[0001] The utility model relates to the technical field of steel processing, in particular to a steel welding surface grinding device. Background Art

[0002] The steel welding surface grinding device is a mechanical equipment designed specifically for treating the surface of steel after welding. It is mainly used to remove welding slag and spatter, smooth the welding area, improve surface quality and prepare for subsequent processes. This device removes impurities generated during the welding process through physical friction, making the weld joint and its surrounding surface smooth and tidy. It can achieve precise grinding of the steel welding surface, ensuring that the treated surface meets specific technical specifications and quality requirements, thereby improving the appearance, durability and subsequent processing effect of the final product.

[0003] After searching, the document of announcement number "CN221792191U" mentioned that "the utility model discloses a steel welding surface grinding device, including a workbench, the top surface of the workbench and near the edge positions on both sides are fixedly connected to the limit plate, and one side of the two limit plates is provided with a slide groove, and the inside of the two slide grooves are slidably connected with an adjustment block, and the two adjustment blocks are rotatably connected with a rotating shaft, and the outer surface of the two rotating shafts and near one end are fixedly connected with two adjustment rods, and one side of the four adjustment rods is fixedly connected with an adjustment column. The utility model pushes the adjustment block to slide in the limit plate through the cylinder. During the sliding process, the adjustment column fixed on the outer surface of the rotating shaft contacts the inner top surface of the driven frame, and under the action of the cylinder force and the resistance of the driven frame, the rotating column is flipped, thereby the welding surface to be ground is turned. The steel plate can be turned over, the operation is convenient, the structure is stable, the turning speed is fast, and the working efficiency of grinding the welded surface of steel is improved. "When in use, it is convenient to operate, the structure is stable, the turning speed is fast, and the working efficiency of grinding the welded surface of steel is improved. However, the above-mentioned device only improves the clamping and turning aspects of the device, and does not improve the grinding facility. It only relies on a single first drive motor to drive the grinding wheel. For large-area or high-hardness steel, the grinding speed is not fast enough, resulting in a long time for the whole process, which reduces production efficiency and increases operation time and cost. Secondly, the grinding force control is not precise. Without an additional power source to assist in controlling the grinding force, it is difficult to achieve fine control by manual or simple mechanical adjustment alone, resulting in uneven grinding, and sometimes over-grinding or under-grinding, affecting the final grinding quality.

[0004] Therefore, we provide a steel welding surface grinding device to solve the above problems. Utility Model Content

[0033] Working principle: First, a steel welding surface grinding device is moved to the working position. When in use, the first step is that the operator first needs to ensure that the workbench 1 is stable and level, and the steel body 222 to be ground is placed in the placement groove 221, and ensure that it is stable and will not shift during the grinding process. Check whether all mechanical components are in good condition, especially whether the driving cylinder 233, the first driving motor 243 and any newly added second driving motor 32 and other electrical components are working properly. According to the size of the steel body 222, the distance between the first fixing plate 212 and the second fixing plate 215 is adjusted using the fixing bolts 214 and the connecting groove 213 so that the placement component 22 can firmly fix the steel. After the adjustment is completed, tighten the fixing bolts 214 to ensure the stability of the support component 21. The second step is to start the driving cylinder 233 and push the fixed base 241 up and down along the slide rod 235 by driving the push rod 234. Or move left and right until the grinding wheel 244 reaches a suitable working position. After adjusting the position, lock the drive cylinder 233 to ensure that the grinding assembly 24 remains fixed during the grinding process, turn on the first drive motor 243, and make the grinding wheel 244 start to rotate. Then, start the second drive motor 32 and provide power to the drive shaft 254 through the power transmission block 31, so that the limited grinding wheel 251 rotates synchronously to enhance the grinding effect. In the third step, after ensuring that all safety measures are in place, start grinding the steel welding surface. The operator should monitor the grinding process and, if necessary, fine-tune the position of the grinding assembly 24 to achieve the best grinding effect. The auxiliary assembly 25 plays an important role at this stage. The limited grinding wheel 251 and the connecting frame 252 work together to keep the motion trajectory of the grinding wheel 244 stable and avoid material damage caused by excessive grinding. In this way, the use process of a steel welding surface grinding device is completed.
