[0002] In modern manufacturing, the quality of molds plays a crucial role in the molding precision, appearance quality, and production efficiency of products. Traditional mold polishing methods often rely on manual operation, requiring operators to manually change different polishing tools to meet the different polishing needs of various parts of the mold. This manual tool changing method has many drawbacks. In addition, traditional dust collection devices are usually in fixed positions and cannot be flexibly adjusted according to the actual dust generated during the polishing of different parts of the mold, resulting in poor dust collection effect.

[0003] The applicant found through a search that a Chinese patent discloses "A Polishing Device for Mold Sidewalls of a Robot", with publication (announcement) number "CN109822431B". This patent mainly achieves high-quality polishing of mold sidewalls by realizing adjustable radial and axial floating forces to ensure maximum contact between the cutting tool and the mold sidewall. However, this device cannot quickly change the grinding wheel. Therefore, we propose a serial robot mold polishing device. Utility Model Content

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0023] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Please see the appendix Figure 1 -Appendix Figure 5This utility model discloses a mold polishing device for a serial robot. A polishing component 2 is fixedly connected to the bottom surface of a mounting base 1. A quick-change component 3 is installed at the bottom of the polishing component 2. The quick-change component 3 includes a connecting block 301, a connecting frame 302, a first grinding mold 303, a second grinding mold 304, a rotating shaft 305, and a first motor 306. A movable groove is formed at the center of the bottom end of the connecting block 301. The inner side of the movable groove contacts the connecting frame 302. One end of the connecting frame 302 is connected to the first grinding mold 303, and the other end is connected to the second grinding mold 304. The center of the connecting frame 302 is fixedly connected to the rotating shaft 305. The rotating shaft 305 is connected to the first motor 306. The central part is fixedly connected to the rotating shaft 305, which is in turn connected to the first motor 306. In this way, the first motor 306 can drive the connecting frame 302 and adjust the position of the mold connected to it through the rotating shaft 305. The bottom rear end of the mounting base 1 is provided with a slide rail 4, and the slide rail 4 is connected to a slider 5. The bottom surface of the slider 5 is fixedly connected to a connecting rod 6, and the side is connected to a movable pull rod 7. The bottom surface of the connecting rod 6 is fixedly connected to a mounting plate 8. The movable pull rod 7 is connected to a second motor 9. Driven by the second motor 9, the movable pull rod 7 can drive the slider 5 to move on the slide rail 4, thereby causing the connecting rod 6 and the mounting plate 8 to produce corresponding displacement.

[0025] In the first embodiment, the connecting frame 302 is L-shaped and its front and rear sides are in close contact with the inner side of the movable groove. The rotating shaft 305 passes through the center of the front and rear sides of the connecting block 301, and a stop block is connected to the front end. The rear end is connected to the drive end of the first motor 306. The rear side of the stop block is in close contact with the front side of the connecting block 301. The first motor 306 is located on the rear side of the connecting block 301. A vacuum cleaner 10 is installed on the front side of the mounting plate 8. The vacuum cleaner 10 is connected to a conveying pipe, which is a corrugated pipe. The second motor 9 is located at the rear end of the bottom surface of the mounting base 1 and is connected to the threaded end of the movable pull rod 7.

[0026] Specifically, the rotating shaft 305 passes through the center of the front and rear sides of the connecting block 301, and a stop block is connected to its front end. Its rear side is in close contact with the front side of the connecting block 301, which can play a good limiting role and prevent the rotating shaft 305 from moving forward during operation. The rear end of the rotating shaft 305 is connected to the drive end of the first motor 306. The first motor 306 is located on the rear side of the connecting block 301. When the first motor 306 starts, it can stably transmit power to the connecting frame 302 through the rotating shaft 305, thereby driving the connecting frame 302 to perform corresponding actions. The second motor 9 is located at the rear end of the bottom surface of the mounting base 1. It is connected to the threaded end of the movable pull rod 7. When the second motor 9 runs, it drives the movable pull rod 7 to perform precise linear movement through thread transmission, so that the slider 5 connected to the movable pull rod 7 moves smoothly on the slide rail 4.

[0027] In embodiment 2, the grinding assembly 2 includes an electric spindle, a tool holder, and a radial floating tool. The electric spindle is connected to the center of the bottom surface of the mounting base 1, the tool holder is connected to the bottom surface of the electric spindle, and the radial floating tool is connected to the bottom surface of the tool holder. The bottom surface of the radial floating tool is connected to the quick-change assembly 3. The electric spindle, the tool holder, and the radial floating tool are coaxially arranged. The first grinding tool 303 is a ball-head grinding head, and the second grinding tool 304 is a conical grinding head. A laser and processor are installed at one end of the mounting base 1, and a connecting shaft is provided at the center of the top surface.

[0028] Specifically, the electric spindle, tool holder, and radial floating tool are coaxially arranged, ensuring efficient power transmission and accurate grinding action, avoiding grinding quality degradation caused by eccentricity and other issues. The laser device can perform high-precision scanning and measurement of the workpiece surface during the grinding process, obtaining accurate data of the workpiece surface and providing accurate reference for the grinding work. The top center of the mounting base 1 is also equipped with a connecting shaft, which can be used to connect the entire equipment with other external devices, such as robotic arms or other motion platforms.

[0029] Working principle:

[0030] First, the mounting base 1 serves as the supporting structure for the entire device, providing a stable mounting foundation for other components. The grinding assembly 2 is fixed to the bottom surface of the mounting base 1, with the electric spindle located at the center of the bottom surface. It provides power for the entire grinding operation, driving the connected tool holder and radial floating tool to rotate. The radial floating tool can float radially within a certain range, thus better conforming to the mold surface. The electric spindle, tool holder, and radial floating tool are coaxially arranged, ensuring efficient power transmission and stable grinding action. At the bottom of the grinding assembly 2 is the quick-change assembly 3. When the device starts working, the first motor 306 drives the rotating shaft 305 to rotate. Since the rotating shaft 305 is fixedly connected to the L-shaped connecting frame 302, which is in close contact with the inner side of the movable groove of the connecting block 301, the rotation of the rotating shaft 305 will drive the connecting frame 302 to move. One end of the connecting frame 302 is connected to a ball-head grinding head, and the other end is connected to a conical grinding head, so that the appropriate grinding tool can be selected for grinding as needed. At the same time, the mounting base 1... The second motor 9 at the rear of the bottom surface operates. Due to the threaded connection between the second motor 9 and the moving pull rod 7, the rotation of the motor causes the moving pull rod 7 to produce linear motion. The moving pull rod 7 drives the slider 5 to move on the slide rail 4, which in turn causes the mounting plate 8, which is connected to the slider 5 through the connecting rod 6, to move. The vacuum cleaner 10 on the front side of the mounting plate 8 works synchronously during the polishing process. It sucks away the debris and dust generated during polishing through the conveying pipe made of corrugated pipe, keeping the working environment clean and preventing dust from affecting the polishing quality and the accuracy of laser scanning. In addition, the laser and processor installed at one end of the mounting base 1 are also operating. The laser scans the mold surface to obtain detailed data of the mold surface. The processor quickly analyzes and processes this data. Based on the analysis results, the polishing parameters and path can be further adjusted to make the polishing work more precise. The connecting shaft at the center of the top surface of the mounting base 1 can be used to connect the device to the serial robot, so that the robot can drive the device to perform a comprehensive polishing operation on the mold. At this point, the entire workflow is completed.
