Description

Technical Field

[0001] This utility model relates to the field of polishing technology, and more specifically, to a handheld polisher for polishing the edges and corners of steel plates. Background Technology

[0002] Steel plates are widely used as a core basic material in many industries such as steel processing, machinery manufacturing, shipbuilding, and building decoration. After the initial processing steps such as cutting and shearing are completed, the edges and corners of steel plates often have defects such as burrs, sharp edges, local protrusions, and uneven surfaces. In the assembly process, uneven steel plate edges and corners can prevent the parts from fitting tightly and accurately, thus affecting the overall structural strength and performance stability of the product. Therefore, grinding the edges and corners of steel plates is a key step to ensure product quality and safety.

[0003] A search revealed that Chinese Patent Publication No. CN208019953U discloses a "handheld grinder, comprising a connected handheld part and a grinding part. The handheld part includes a handheld housing and a power component located inside the handheld housing to drive the grinding part. An air inlet is provided at the end of the handheld housing away from the grinding part, and an air outlet is provided at the connection point of the grinding part near the handheld housing. The handheld housing has a sliding port that penetrates the handheld housing and communicates with the air inlet. A main limiting strip is provided on the inner wall of the handheld housing at the air inlet. The handheld housing has a main limiting groove for the main limiting strip to engage and a main filter plate that can slide along the sliding port to the air inlet to cover the air inlet. The handheld housing has a fixing member for movably fixing the position of the main filter plate after it covers the air inlet. The beneficial effect of this utility model is that the handheld grinder can easily clean the dust accumulated in the air inlet." However, the following defects still exist: The current device cannot effectively cool the grinding area. During prolonged grinding of steel plates, the continuous high-speed friction between the grinding device and the steel plate surface generates a large amount of heat. When this heat cannot be dissipated in time, the temperature of the grinding device rises sharply. Excessive temperature can cause various types of damage to the grinding device, leading to reduced hardness, accelerated wear, and rapid dulling of the originally sharp abrasive particles, significantly shortening the lifespan of the grinding device and increasing operating costs. Therefore, a handheld grinding machine for grinding the edges and corners of steel plates is proposed. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0018] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] like Figure 1 As shown, this embodiment proposes a handheld grinder for grinding the edges and corners of steel plates, including a handheld main body 1, a cooling component 2 for cooling the grinding part is provided on one side of the handheld main body 1, and an auxiliary component 3 for supporting the grinding is provided on one side of the handheld main body 1. like Figure 2 and Figure 3As shown, the cooling component 2 includes a fixed column 201 fixedly connected to one side of the handheld host body 1. A connecting frame 202 is fixedly connected to one end of the fixed column 201. A servo motor 203 is bolted to one side of the connecting frame 202. A grinding wheel 204 is coaxially arranged at the output end of the servo motor 203. The grinding wheel 204 is rotated by the servo motor 203 to grind the edges and corners of the steel plate. A connecting frame 205 is fixedly connected to the inner wall of the connecting frame 202. Multiple spray pipes 206 are fixedly connected to one side of the connecting frame 205. A connecting pipe 207 is arranged on one side of the connecting frame 205. External water is transported into the connecting frame 205 through the connecting pipe 207, and then the external water is evenly transported to the surface of the grinding wheel 204 by the spray pipe 206 on one side of the connecting frame 205. During the polishing process, the handheld host body 1 provides power support, and the servo motor 203 drives the polishing wheel 204 to rotate at high speed to polish the edges and corners of the steel plate. When polishing the edges and corners of the steel plate for a long time, the external water tank is connected to the connecting pipe 207, and external water is supplied to the connecting frame 205 through the connecting pipe. The external water is evenly sprayed out through multiple spray pipes 206 to cool down the polishing wheel 204 and the polished part of the steel plate, preventing the polishing effect of the steel plate edges and corners from decreasing due to excessive temperature. This not only effectively solves the problem of heat generated during the polishing process, but also reduces the risk of damage to the polishing wheel 204 and the steel plate due to high temperature, and improves the polishing quality of the steel plate edges and corners.

[0021] like Figure 4 As shown, the auxiliary component 3 includes a clamp 301 disposed on the outer wall of the fixed column 201, and a connecting column 302 is fixedly connected to the outer wall of the clamp 301. The connecting column 302 is stably fixed to the outer wall of the fixed column 201 by the clamp 301. When the operator holds the grinder for grinding, he can better control the position and force of the grinder with the help of the connecting column 302, making the grinding operation more flexible and stable. Especially when performing some fine grinding or grinding operations that require greater force control, it can improve the grinding accuracy.

[0022] like Figure 5 As shown, a baffle 4 is slidably connected to one side of the connecting frame 205, and multiple positioning holes 5 are provided on one side of both the connecting frame 205 and the baffle 4. The baffle 4 is fixed in different positions of the connecting frame 202 through the positioning holes 5. During the grinding process, the position of the baffle 4 is adjusted according to actual needs to control the spraying range of the spray pipe 206 or protect the surrounding environment from external water splashes.

[0023] like Figure 5As shown, scrapers 6 are slidably connected to the outer walls of multiple spray pipes 206, and vertical plates 7 are fixedly connected to the top of the scrapers 6. When it is necessary to clean the spray pipes 206, the operator can push the vertical plates 7 to drive the scrapers 6 to slide on the outer walls of the spray pipes 206. The scrapers 6 scrape away impurities and dirt from the outer walls of the spray pipes 206, keeping the spray pipes 206 clean and ensuring that external water can be sprayed out smoothly.

[0024] like Figure 5 As shown, the bottom of the clamp 301 is threaded with two support columns 8, and the bottom of the two support columns 8 is fixedly connected with a support pad 9. When handheld operation is not required, the support columns 8 and the support pad 9 can stably support the handheld main unit 1, so that the grinding wheel 204 is away from the worktable surface, avoiding contact between the grinding wheel 204 and the worktable surface and causing damage.

[0025] like Figure 4 As shown, a protective cover 10 is bolted to one side of the connecting bracket 202, and multiple heat dissipation holes 11 are provided through one side of the protective cover 10. The protective cover 10 provides stable protection for the servo motor 203, and the heat dissipation holes 11 dissipate the heat generated by the servo motor 203 during operation, preventing the servo motor 203 from being damaged due to overheating.

[0026] like Figure 2 As shown, two semicircular plates 12 are fixedly connected to one side of the handheld host body 1, and a plastic sheath 13 is provided on one side of the two semicircular plates 12. The plastic sheath 13 on the semicircular plates 12 protects the circuit of the handheld host body 1, preventing the conductors inside the circuit from being subjected to large stress due to frequent and excessive bending, which could lead to breakage, loosening, or other problems.

[0027] like Figure 4 As shown, the outer wall of the connecting column 302 is provided with a plastic soft sleeve 14, and the outer wall of the plastic soft sleeve 14 has multiple protective grooves 15. When the operator holds the connecting column 302, the plastic soft sleeve 14 can provide a soft grip and reduce hand discomfort, while the protective grooves 15 can increase the friction between the hand and the plastic soft sleeve 14, prevent the hand from slipping, and improve the stability of the grip.

[0028] Specifically, when using this handheld grinder for steel plate edge grinding: During the grinding process, the main body 1 provides power support, and the servo motor 203 drives the grinding wheel 204 to rotate at high speed to grind the edges of the steel plate. When grinding the edges of the steel plate for an extended period, an external water tank is connected to a connecting pipe 207. External water is supplied to the connecting frame 205 through the connecting pipe. The external water is evenly sprayed out through multiple spray pipes 206 to cool the grinding wheel 204 and the area of ​​the steel plate being ground, preventing a decrease in grinding effect due to excessive temperature. This not only effectively solves the problem of heat generated during grinding but also reduces the risk of damage to the grinding wheel 204 and the steel plate due to high temperature, thus improving the grinding quality of the steel plate edges (e.g., ...). Figure 2 and Figure 3 As shown); the connecting post 302 is stably fixed to the outer wall of the fixing post 201 by the clamp 301. When the operator holds the grinder for grinding, the connecting post 302 can be used to better control the position and force of the grinder, making the grinding operation more flexible and stable. Especially when performing some fine grinding or grinding operations that require greater force control, it can improve the accuracy of grinding (such as...). Figure 4 (As shown).

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
