[0011] like Figure 1 and Figure 2As shown, a portable free-edge one-time forming grinder comprises a handle 1, a housing 2, a motor 3, a power interface 4, a motor transmission shaft 5, a driving gear 6, a driven gear 7, a coarse grinding body 8, a fine grinding body 11 and a driven gear transmission shaft 12. The handle 1 is mounted on the housing 2, and the motor 3, the power interface 4, the motor transmission shaft 5, the driving gear 6 and the driven gear 7 are all arranged in the housing 2. One end of the motor 3 is connected to the power interface 4, and the other end is connected to the motor transmission shaft 5. The power interface 4 is connected to electric energy or compressed gas energy. The motor transmission shaft 5 is connected to the driving gear 6, and the driving gear 6 and the driven gear 7 are meshed with each other. The driven gear 7 is respectively connected to the driven gear transmission shaft 12, and the coarse grinding body 8 and the fine grinding body 11 are respectively fixed to the driven gear transmission shafts 12. On the shaft 12, a coarse grinding groove 9 is provided on the coarse grinding body 8, and a fine grinding groove 10 is provided on the fine grinding body 11. It is necessary to align the coarse grinding groove 9 processed according to the required size and roughness and the fine grinding groove 10 of the specified size and roughness with the free edge of the structure to be processed, and then translate the device in the direction from coarse to fine. The device is mainly composed of a coarse grinding body 8 and a fine grinding body 11 made of materials such as diamond with a certain size, roughness and wear resistance, which are respectively fixed on the driven gear transmission shaft 12. At the same time, the driven gear transmission shaft 12 is respectively connected and fixed with the driven gear 7. The driven gear 7 and the driving gear 6 according to the set specifications are engaged with each other, so that they can run at a certain number of revolutions when the driving gear 6 rotates, and the driving gear 6 is fixed to the motor transmission shaft 5 in a certain way. On the shell 2, when the motor 3 drives the motor transmission shaft 5 to rotate, the driving gear 6 can rotate together at a certain number of revolutions, and then the motor 3 is connected to the power interface 4 connected to the electric energy or compressed gas energy, and the shell 2 with a convenient and practical appearance is used to wrap the motor 3, the power interface 4, the motor transmission shaft 5, the driving gear 6, the driven gear 7 and a part of the driven gear transmission shaft 12 connected to each other in a specific way under the premise of ensuring tightness, reliability and safety, and then the handle 1 is installed at a suitable position of the shell 2, and after the kinetic energy is connected to the power interface 4, the handle 1 is manually operated to align the coarse grinding groove 9 and the fine grinding groove 10 with the free edge of the structure to be processed, and then the device is translated from coarse to fine so that it can complete the expected processing after passing through the free edge of the structure once. Precision and effect, the portable structural free edge one-time forming grinder of the present invention is mainly aimed at the free edges (i.e. right-angle edges) of all structural parts (plates and profiles, etc.) in the manufacturing industry, especially the shipbuilding industry. These positions need to be polished, the purpose is to allow the protective coating material to effectively adhere to the free edge position that is difficult to adhere to, so as to achieve the purpose of protecting the steel structure. For this reason, most positions on the ship, such as: seawater ballast tanks, double-side places of bulk carriers, empty tanks of bulk carriers and oil tankers, and cargo oil tanks of crude oil tankers, etc., according to the requirements, the internal structural parts must be chamfered before painting, the radius must be at least 2mm, and the burrs must be removed. The present invention can achieve the coating requirements in one processing while ensuring the minimum radius of 2mm.It not only improves the construction quality but also reduces a lot of construction time and cost. It also has certain intelligent applications. Considering the actual situation of the current industry, the requirement that the chamfer radius of the free edge of the structure is at least 2mm, the grinding wheel is divided into two types of coarse and fine processing with a certain size of arc. The motor and shaft belt gear drive the grinding wheel to rotate at high speed, and the free edge of the structure is ground in the order of coarse first and then fine, so that it can reach a chamfer radius of at least 2mm in one pass under the action of the coarse grinding wheel, and the burrs on the surface can be removed after grinding with the fine grinding wheel, so that the coating requirements can be met in one grinding.
