Description

Technical Field

[0001] This utility model belongs to the field of workpiece surface polishing technology, specifically relating to a multi-station rotary polishing table. Background Technology

[0002] Polishing tables are key equipment for workpiece surface treatment in manufacturing. As the core component of polishing machines, they provide a stable working environment for polishing, grinding, deburring and other processes. They are usually equipped with polishing wheels, workpiece fixing devices and drive components. Some also integrate auxiliary structures such as dust collection and liquid spraying. Parameters such as speed and pressure can be flexibly adjusted. The drive components drive the polishing elements to achieve workpiece surface processing. This equipment is mostly made of sturdy materials such as steel to ensure operational stability. It is widely used in the processing of metal parts, tiles, optical lenses and other fields, and can effectively improve the surface finish and overall quality of workpieces. However, traditional polishing tables have significant limitations in practical use. Their operation mode is mostly single-workpiece processing. Operators must first fix a single workpiece on the worktable, and after completing the grinding and polishing process, they must first remove the processed workpiece, clean the table, and re-clamp the next workpiece before starting a new round of processing. During this process, the polishing mechanism will be forced to interrupt its operation due to workpiece disassembly and assembly, forming a long non-processing waiting gap. It is impossible to achieve continuous loading, processing, and unloading of workpieces. This intermittent operation mode wastes a lot of effective equipment operating time, directly restricts the improvement of overall polishing efficiency, and makes it difficult to meet the high-efficiency requirements of large-scale production. To address the aforementioned issues, this application proposes a multi-station rotary polishing table. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0015] Please see Figure 1-6 The present invention provides the following technical solution: a multi-station rotary polishing table, including a base plate 1, a collar 5 fixedly connected to the upper surface of the base plate 1, a rotating table 2 rotatably connected inside the collar 5, a brake motor 11 and a controller 4 respectively arranged above the base plate 1, a serrated ring 9 fixedly connected to the outer surface of the rotating table 2, a gear 10 fixedly connected to the output end of the brake motor 11, the gear 10 meshing with the serrated ring 9, two sets of placement platforms 13 fixedly connected to the upper surface of the rotating table 2, two electric push rods 16 arranged above each placement platform 13, and a polishing machine 18 arranged above the rotating table 2; In this embodiment, the brake motor 11 is a DC geared brake motor, which combines stable driving force and precise braking performance. It can ensure that the turntable 2 can be quickly positioned and locked after the work position is switched, so as to avoid displacement during processing. At the same time, the controller 4 is a PLC programmable logic controller, which can accurately coordinate the start and stop of the brake motor 11, the extension and retraction of the electric push rod 16 and the operating parameters of the polishing machine 18 through preset programs, so as to realize the coordinated work of each component. The electric push rod 16 is a DC electric push rod with adjustable thrust and the stroke can be adapted to the height of the workpiece to meet the stable clamping requirements of workpieces of different specifications. The polishing machine 18 is a vertical high-speed polishing machine, equipped with replaceable wool wheel or nylon wheel polishing heads, and the speed is adjustable, which can adapt to the polishing process requirements of workpieces of different materials such as metal and plastic.

[0016] Specifically, a support plate 3 is fixedly connected to the back of the controller 4. The bottom surface of the support plate 3 is fixedly connected to the upper surface of the base plate 1. In this embodiment, the controller 4 is mounted at a suitable height above the base plate 1 by the support plate 3, which not only avoids the controller 4 from being directly exposed to the table surface and affected by dust, but also makes it convenient for operators to observe and operate the control panel.

[0017] Specifically, two sets of connecting columns 7 are fixedly connected to the bottom surface of the base plate 1. Each connecting column 7 is fixedly connected to a support ring 8 at its bottom end. In this embodiment, the height of the base plate 1 is raised by the connecting columns 7, and the contact area with the ground is increased by the support ring 8, thereby improving the overall stability of the equipment placement. At the same time, the bottom space is reserved for easy cleaning and maintenance.

[0018] Specifically, a fixing ring 6 is fixedly connected to the outer surface of the collar 5. The bottom surface of the fixing ring 6 is fixedly connected to the upper surface of the base plate 1. In this embodiment, the fixing ring 6 enhances the connection strength between the collar 5 and the base plate 1, preventing the collar 5 from loosening under force when the rotating table 2 rotates, and ensuring the stability of the rotating structure.

[0019] Specifically, a connecting frame 12 is fixedly connected to the front of the brake motor 11, and the bottom surface of the connecting frame 12 is fixedly connected to the upper surface of the base plate 1. In this embodiment, the brake motor 11 is firmly fixed to the base plate 1 by the connecting frame 12 to ensure that there is no shaking when the motor runs and the gear 10 meshes with the sawtooth ring 9, thus ensuring transmission accuracy.

[0020] Specifically, each electric push rod 16 has a fixed bracket 14 fixedly connected to its outer surface, and the bottom surface of each fixed bracket 14 is fixedly connected to the upper surface of the placement table 13. In this embodiment, the electric push rod 16 is stably installed on the placement table 13 by the fixed bracket 14 to prevent the push rod from shifting when it extends or retracts, and to ensure the clamping and positioning accuracy of the workpiece.

[0021] Specifically, each electric push rod 16 has a protective ring 15 fixedly connected to its telescopic end. Each protective ring 15 is made of rubber. In this embodiment, the rubber protective ring 15 directly contacts the workpiece surface, which can increase friction and improve clamping stability, and avoid scratches on the workpiece surface caused by rigid contact.

[0022] Specifically, a support frame 17 is fixedly connected to the bottom surface of the polishing machine 18. The bottom surface of the support frame 17 is fixedly connected to the upper surface of the base plate 1. In this embodiment, the polishing machine 18 is precisely fixed above the corresponding work station by the support frame 17, ensuring that the polishing head and the workpiece on the placement table 13 are in the preset processing position, while enhancing the anti-vibration capability of the polishing machine 18 during operation.

[0023] The working principle and usage process of this utility model are as follows: In use, the controller 4 first presets parameters such as the rotation speed of the polishing machine 18, the clamping pressure of the electric push rod 16, and the start / stop interval of the brake motor 11. Then, the operator places the workpieces to be processed on each of the placement tables 13. The controller 4 then activates the electric push rod 16 corresponding to each placement table 13. Its telescopic end drives the rubber protective ring 15 to move closer to the workpiece until all workpieces on the placement tables 13 are securely clamped, preventing displacement or scratches during processing or rotation. Subsequently, the controller 4 activates the brake motor 11. The gear 10 at its output end drives the serrated ring 9 on the outer surface of the rotating table 2 to rotate, causing one of the placement tables 13 containing the workpiece to rotate precisely below the polishing machine 18. The brake motor 11 then locks, and the polishing machine 18 starts to operate on the placement table 13. The workpiece on the 3rd table is processed. During the processing, the rotating table 2 remains stationary. After the workpiece on the placement table 13 is processed, the polishing machine 18 pauses, and the brake motor 11 restarts to drive the rotating table 2 to rotate. The next placement table 13 with an unprocessed workpiece is rotated to the underside of the polishing machine 18 and locked. The polishing machine 18 restarts to continue processing. At the same time, the operator can unload the completed placement table 13 that has been moved away from the polishing station. After unloading the finished product, a new workpiece to be processed is immediately re-clamped. This realizes the parallel process of "polishing machine 18 continuously processing and manual synchronous unloading and loading". Through the cyclic rotation of the rotating table 2, all placement tables 13 pass through the polishing station in sequence. With the continuous manual replenishment operation, the downtime waiting time of traditional equipment is completely eliminated, and the overall polishing efficiency is maximized.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
