Description

Technical Field

[0001] This utility model relates to the field of polishing technology, and more specifically, to a polishing device. Background Technology

[0002] In the processing of hardware parts, sheet metal, and other workpieces, the grinding process is a key step in improving the surface precision and appearance quality of the workpieces. With the increasing demand for automation in the manufacturing industry, traditional manual or semi-automatic grinding equipment can no longer meet the efficiency and safety requirements of mass production. Although existing grinding equipment has explored automation, it still has core technical defects: the loading and unloading of most equipment is done sequentially with the grinding process, requiring the machine to stop to complete the loading and unloading of workpieces, resulting in significant waiting gaps between processes and limited processing capacity per unit time; some automated grinding equipment is only equipped with a single loading and unloading mechanism, which is prone to spatial interference with the grinding device when adapting to a double-sided grinding structure, further restricting processing efficiency; at the same time, manual loading and unloading also poses safety hazards such as burns from high-temperature workpieces and dust hazards.

[0003] For example, Chinese patent CN111941237A discloses a hardware grinding device. This device uses a multi-directional slide rail to achieve all-around grinding of the workpiece, possessing batch processing capabilities and fully automatic grinding functions, thus improving processing accuracy and efficiency to a certain extent. However, this patent does not solve the core problem of automated loading and unloading. In actual use, manual intervention is still required for workpiece loading and unloading operations, which is not only cumbersome and time-consuming, but also poses a risk of burns to operators due to the high surface temperature of the workpiece after grinding. Furthermore, the single loading mechanism cannot coordinate with the double-sided grinding structure, making continuous production difficult and restricting the improvement of equipment capacity and optimization of safety performance.

[0004] To address the issues of poor process coordination, insufficient automation, and the need to improve production efficiency and safety in existing grinding equipment, this application proposes a grinding equipment with optimized structure. By rationally arranging the grinding device, rotating mechanism, and loading / unloading mechanism, the processing flow is made continuous and automated, meeting the actual needs of mass production. Utility Model Content

[0005] Based on this, in order to solve the problems of poor process coordination, insufficient automation, and the need to improve production efficiency and safety in traditional equipment, this utility model provides a grinding device, the specific technical solution of which is as follows: A polishing device, including First grinding device; A frame, wherein the frame is provided with a first opening and a second opening; A rotating device is provided inside the machine frame, and the rotating device is provided with a plurality of tooling for fixing the workpiece to be processed; The second grinding device, both the first grinding device and the second grinding device are located inside the frame. The first grinding device is located on one side of the rotating device, and the second grinding device is located on the other side of the rotating device. The rotating device is used to drive the tooling to rotate and circulate through the first opening, the first grinding device, the second opening and the second grinding device. A first robotic arm is located outside the first opening. The first robotic arm is used to place the workpiece to be processed onto the tooling through the first opening and to remove the processed workpiece. The second robotic arm is located outside the second opening. The second robotic arm is used to place the workpiece to be processed onto the tooling through the second opening and to remove the processed workpiece.

[0006] The aforementioned grinding equipment features a rotating device that drives the tooling to circulate through a first opening, a first grinding device, a second opening, and a second grinding device. Combined with the symmetrically arranged first and second grinding devices on both sides, this allows for continuous grinding of the workpiece during the cycle, avoiding the waiting time required for loading and unloading in traditional equipment. The simultaneous operation of the two grinding devices further increases the processing capacity per unit time, adapting to batch production needs. The first and second robotic arms independently complete loading and unloading operations at the two openings of the frame, enabling parallel processing of workpiece loading / unloading and grinding processes without manual intervention in the grinding area. This eliminates the safety hazards associated with manual loading and unloading, and reduces reliance on manual labor and operational intensity. The automated operation of the robotic arms also ensures consistent workpiece clamping, reducing the impact of human error on processing quality. The grinding devices and loading / unloading mechanisms work in an orderly and coordinated manner through the frame and rotating device. The layout of the two openings and two robotic arms avoids spatial interference between loading / unloading and grinding actions, improving the stability of equipment operation. This grinding equipment solves the problems of poor process coordination, insufficient automation, and the need to improve production efficiency and safety inherent in traditional equipment.

[0022] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0023] like Figures 1-2 As shown, a grinding device according to one embodiment of the present invention includes a first grinding device 1, a frame 2, a rotating device 3, a second grinding device 4, a first robotic arm, and a second robotic arm. The frame 2 is provided with a first opening 5 and a second opening 6. The rotating device 3 is located inside the frame 2 and is provided with a plurality of fixtures 7 for fixing the workpiece to be processed. The first grinding device 1 and the second grinding device 4 are both located inside the frame 2. The first grinding device 1 is located on one side of the rotating device 3, and the second grinding device 4 is located on the other side of the rotating device 3. The rotating device 3 is used to drive the fixtures 7 to rotate and circulate through the first opening 5, the first grinding device 1, the second opening 6, and the second grinding device 4. The first robotic arm is located outside the first opening 5 and is used to put the workpiece to be processed onto the fixture 7 through the first opening 5 and to take out the processed workpiece. The second robotic arm is located outside the second opening 6 and is used to put the workpiece to be processed onto the fixture 7 through the second opening 6 and to take out the processed workpiece.

[0024] The aforementioned grinding equipment, with its rotating device 3 driving the tooling 7 through the first opening 5, the first grinding device 1, the second opening 6, and the second grinding device 4, and in conjunction with the symmetrically arranged first and second grinding devices 4 on both sides, allows the workpiece to undergo continuous grinding during the cycle, avoiding the waiting time for loading and unloading during traditional equipment downtime. The simultaneous operation of the two grinding devices further increases the processing capacity per unit time, adapting to batch production needs. The first and second robotic arms independently complete loading and unloading operations corresponding to the two openings of the frame 2, enabling parallel processing of workpiece loading / unloading and grinding processes without manual intervention in the grinding area. This eliminates the safety hazards associated with manual loading and unloading, and reduces reliance on manual labor and operational intensity. The automated operation of the robotic arms also ensures consistent workpiece clamping, reducing the impact of human error on processing quality. The grinding devices and loading / unloading mechanisms form an orderly collaboration through the frame 2 and the rotating device 3. The layout of the two openings and two robotic arms avoids spatial interference between loading / unloading and grinding actions, improving the stability of equipment operation. This grinding equipment solves the problems of poor process coordination, insufficient automation, and the need to improve production efficiency and safety inherent in traditional equipment.

[0025] like Figures 1-2As shown, in one embodiment, the rotating device 3 includes a disk 31 and a first driving block 32. The first driving block 32 is disposed inside the frame 2, and the disk 31 is disposed on the output end of the first driving block 32. The first driving block 32 is used to drive the disk 31 to rotate. A plurality of tooling 7 are arranged at intervals on the disk 31, and the plurality of tooling 7 are arranged around the center line of the disk 31. Thus, by adopting the core structure of "first drive block 32 + disk 31", the first drive block 32 directly drives the disk 31 to rotate. The power transmission path is short and the loss is small, ensuring the smoothness and uniformity of the disk 31's rotation process. This provides stable support for the cyclic flow of tooling 7 and workpieces, avoiding processing errors caused by rotational fluctuations. Multiple tooling 7 are evenly distributed around the center line of the disk 31 at intervals. On the one hand, this ensures that each tooling 7 can accurately align with the first / second opening 6 and the corresponding grinding device during rotation, achieving precise positioning for loading, unloading, and grinding. On the other hand, it maximizes the use of the circumferential space of the disk 31, simultaneously carrying multiple workpieces to participate in the cyclic operation, further improving batch processing efficiency.

[0026] like Figures 2-3As shown, in one embodiment, the first polishing device 1 includes a first moving mechanism 11 and a first polishing machine 123; the first moving mechanism 11 is mounted on the frame 2, and the first polishing machine 12 is mounted on the moving end of the first moving mechanism 11.

The first moving block 112 is mounted on the first slide rail 113 and slidably connected to the first slide rail 113; the first threaded rod 114 is connected to the output end of the first motor, the first motor is used to drive the first threaded rod 114 to rotate, the first threaded rod 114 passes through the first moving platform 111 and is threadedly connected to the first moving platform 111; the first grinding device 12 includes a first bracket 121, a first two-axis linear module 122 and a first grinding machine 123; the first bracket 121 is mounted on the first moving platform 111, the first two-axis linear module 122 is mounted on the first bracket 121, and the first grinding machine 123 is mounted on the first two-axis linear module 123. On the moving end of the linear module 122, the first two-axis linear module 122 is used to drive the first polishing machine 123 to move in the horizontal and vertical directions; the second polishing device 4 includes a second moving mechanism and a second polishing equipment structure; the second moving mechanism is mounted on the frame 2, and the second polishing equipment structure is mounted on the moving end of the second moving mechanism; the second moving mechanism is used to drive the second polishing equipment structure to move closer to and away from the rotating device 3; the second moving mechanism includes a second moving platform, a second moving block, a second slide rail, a second threaded rod, and a second motor; the second motor and the second slide rail are both mounted on the frame 2; the second moving block is mounted on the second moving platform. At the bottom, the second moving block is mounted on the second slide rail and slidably connected to the second slide rail; the second threaded rod is connected to the output end of the second motor, and the second motor is used to drive the second threaded rod to rotate. The second threaded rod passes through the second moving platform and is threadedly connected to the second moving platform; the second grinding equipment includes a second bracket, a second two-axis linear module, and a second grinding machine; the second bracket is mounted on the second moving platform, the second two-axis linear module is mounted on the second bracket, and the second grinding machine is mounted on the moving end of the second two-axis linear module. The second two-axis linear module is used to drive the second grinding machine to move in the horizontal and vertical directions.Thus, the moving mechanism of the grinding device adopts a transmission structure of "motor + threaded rod + slide rail". The motor drives the threaded rod to rotate, and the slide rail guides and limits the moving platform, enabling the grinding device to approach / The linear motion away from the rotating device 3 ensures high transmission precision and small positioning error, guaranteeing accurate distance control between the grinder and the workpiece, thus improving grinding fit and processing accuracy. The grinding mechanism is equipped with a two-axis linear module, which can drive the grinder to move flexibly in the horizontal and vertical directions. It can adjust the grinding angle and position according to the workpiece's shape and grinding area (such as the side, end face, and edges), adapting to the diverse grinding needs of workpieces of different shapes and specifications, without the need to change the special tooling 7, thus expanding the processing range of the equipment. The first and second grinding devices 4 are symmetrical in structure and independently controlled, which can simultaneously perform the same process on different workpieces, or perform different processes (such as rough grinding and fine grinding) on ​​the same workpiece separately, realizing parallel or hierarchical processing of grinding processes, further improving processing efficiency and the sense of layering of processing quality. At the same time, the two devices are redundant backups for each other, and can be switched to single device operation when a single device is being maintained, reducing the risk of production line downtime.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
