Description

Technical Field

[0001] This utility model relates to the field of workpiece rough surface grinding technology, specifically a grinding device for the welded surface of a machine frame. Background Technology

[0002] Although existing workpiece surface grinding equipment has been continuously innovated and developed to basically meet people's needs, there is still room for improvement.

[0003] For example, patent document CN216265300U discloses a high-precision grinding and polishing device for sheet metal. Addressing the problem of poor removal of impurities adhering to the surface of the polishing belt, thus affecting the polishing precision of the sheet metal surface, the following solution is proposed: It includes a mounting frame and a polishing belt disposed inside the mounting frame. The mounting frame also includes two rotating shafts. Impurities are centrally processed through a dust collection hood, and the meshing transmission of two gears causes the cleaning roller and polishing belt to move synchronously towards the center. This allows the cleaning roller to rotate and clean the impurities adhering to the surface of the polishing belt. Furthermore, the addition of a scraper further improves the removal effect of impurities on the polishing belt surface, thereby effectively improving the precision of the sheet metal during polishing. Some impurities on the surface of the polishing belt are drawn into the dust collection cabinet by the action of the guide plate for dust collection, facilitating centralized processing of impurities.

[0004] The aforementioned grinding equipment can clean impurities adhering to the polishing belt, but its cleaning roller is in continuous contact with the polishing belt, and the polishing belt will also continuously grind the cleaning roller, causing the cleaning roller's cleaning effect on impurities to decrease rapidly, affecting the stability of its actual cleaning. Therefore, a grinding device for the welded surface of the frame is needed to solve the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a grinding device for the welding surface of a frame, so as to solve the problem that although the grinding equipment mentioned in the background art can clean the impurities adhering to the polishing belt, its cleaning roller is in continuous contact with the polishing belt, and the polishing belt will also continuously grind the cleaning roller, which causes the cleaning roller to rapidly decrease its cleaning effect on impurities and affects the stability of its actual cleaning.

[0006] This utility model provides the following technical solution: a grinding device for the welding surface of a machine frame, including a grinding mechanism, wherein the grinding mechanism includes a mounting frame and a polishing belt driven by an electric roller; It also includes a cleaning mechanism, which includes a partition frame bolted to the mounting bracket; And, a fixing seat bolted to the partition frame and located at the bottom of the mounting frame, wherein a mounting seat is spring-connected to the fixing seat; The mounting base is equipped with a vibration motor connected to an impact ball that is in contact with the surface of the mounting frame; It also includes a collection mechanism, placed below the separator, for collecting impurities.

[0007] To achieve the above technical solution, the mounting base is located in the area below the polishing belt. With the help of a vibration motor, the impact ball will continuously drive the polishing belt to strike the bottom of the polishing belt, thereby causing the polishing belt to vibrate continuously and shake off impurities. Compared with the existing technology, this device can make the impact ball vibrate and impact the surface of the polishing belt for a long time, ensuring the cleaning effect of the polishing belt.

[0008] As a further improvement to this utility model, the surface of the polishing belt is provided with several zones with different grit numbers.

[0009] The above technical solution improves the adaptability of polishing belts for grinding.

[0010] As a further improvement to this utility model, the number of impact balls is at least two and they are evenly distributed along the Y-axis of the mounting base.

[0011] The above technical solution improves the impact effect on the polishing belt.

[0012] As a further improvement to this utility model, a limiting rod is connected to the fixed base along the movement direction of the mounting base, and the limiting rod passes through a through hole on the surface of the mounting base.

[0013] The above technical solution improves the guiding performance of the mounting base's vertical movement.

[0014] As a further improvement to this utility model, the collection mechanism includes an open-shaped collection box bolted to the bottom of the separator frame, and the inside of the collection box contains water to adhere to impurities.

[0015] The above technical solution facilitates the collection of impurities that fall off the polishing belt.

[0016] As a further improvement to this utility model, the open area of ​​the collection box is larger than the area of ​​the mounting frame, so as to completely cover the polishing belt.

[0017] The above technical solution makes it easier for impurities to enter the collection box.

[0018] As a further improvement to this utility model, a water guide pipe with a sealing plug is embedded on the outside of the collection box, and the bottom of the inner wall of the collection box is inclined toward the water guide pipe.

[0019] Implementing the above technical solution facilitates water exchange and maintenance of the collection tank's interior.

[0020] The technical effects and advantages of this utility model are as follows: 1. This utility model uses a mounting base located in the area below the polishing belt. In conjunction with a vibration motor, the impact ball continuously drives the polishing belt to strike the area below the polishing belt, thereby causing the polishing belt to vibrate continuously and shake off impurities.

[0021] 2. Compared with the prior art, this device can make the impact ball vibrate and impact the surface of the polishing belt for a long time, ensuring the cleaning effect of the polishing belt. Attached Figure Description

[0028] Example: Referring to the accompanying drawings, this utility model provides a grinding device for the welding surface of a machine frame, including a grinding mechanism 100. The grinding mechanism 100 includes a mounting frame 111 and a polishing belt 112 driven by an electric roller. The surface of the polishing belt 112 is provided with several partitions with different grinding grits. It also includes a cleaning mechanism 200, which includes a partition frame 211 bolted to the mounting frame 111; And, a fixing seat 212 is bolted to the partition frame 211 and located at the bottom of the mounting frame 111, and a mounting seat 213 is spring-connected to the fixing seat 212; The mounting base 213 is equipped with a vibration motor connected to an impact ball 214 that is in contact with the surface of the mounting bracket 111. There are at least two impact balls 214 that are evenly distributed along the Y-axis of the mounting base 213. A limit rod 215 is connected to the fixed base 212 along the movement direction of the mounting base 213, and the limit rod 215 passes through a through hole on the surface of the mounting base 213. It also includes a collection mechanism 300, which is placed below the separator 211 to collect impurities. The collection mechanism 300 includes an open collection box 311 bolted to the bottom of the separator 211. The collection box 311 contains water to adhere to the impurities. The open area of ​​the collection box 311 is larger than the area of ​​the mounting frame 111, completely covering the polishing belt 112. A water guide pipe 312 with a sealing plug is embedded on the outside of the collection box 311, and the bottom of the inner wall of the collection box 311 is inclined toward the water guide pipe 312.

[0029] In use, the electric roller of the mounting frame 111 drives the polishing belt 112 to rotate continuously, polishing the weld surface of the workpiece. Some impurities will remain on the polishing belt 112. As the polishing belt 112 moves, the vibration motor on the mounting base 213 is activated, causing the impact ball 214 to continuously impact the polishing belt 112 in contact with it. This causes the polishing belt 112 above the collection box 311 to vibrate, causing the impurities to detach from that area of ​​the polishing belt 112 and fall into the collection box 311, where they are adhered and fixed by the water inside the collection box 311.
