Description
Technical Field
[0001] This utility model relates to the field of polishing machine technology, specifically to a workpiece rotating base for a polishing machine. Background Technology
[0002] In the field of polishing machine technology, polishing of circular workpieces is a common requirement, and the processing quality directly depends on the stability of the workpiece during the polishing process, the uniformity of polishing, and the flexibility of operation. However, the workpiece support structures of polishing machines currently on the market are gradually revealing many problems that urgently need to be solved in practical applications, making it difficult to meet the requirements of high-precision and high-efficiency polishing operations. Existing polishing machines generally lack reliable clamping and limiting designs in their workpiece placement mechanisms. When polishing round workpieces, the workpieces are prone to shifting or shaking due to the grinding force applied by the polishing mechanism, resulting in a decrease in the polishing accuracy of the workpiece surface, defects such as localized over-grinding and uneven polishing texture, which seriously affect product quality and may even cause workpiece scrapping, increasing production costs. Although some clamping structures can fix the workpiece, their adaptability is poor, and they can only be used for round workpieces of specific sizes. When dealing with workpieces of different diameters, it is necessary to frequently change fixtures or adjust the equipment, which is cumbersome and significantly reduces processing efficiency. Furthermore, during polishing, the workpiece cannot be rotated, which affects the quality and uniformity of polishing. Therefore, it is necessary to design a workpiece rotating base for polishing machines to solve the above problems. Utility Model Content
[0003] The purpose of this utility model is to provide a workpiece rotating base for a polishing machine to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a workpiece rotating base for a polishing machine, comprising a polishing machine body, wherein a placement mechanism is provided on the top of the polishing machine body, and a polishing mechanism is provided on the rear side of the top of the polishing machine body; The placement mechanism includes a first hydraulic cylinder, which is fixedly connected to the top of the polishing machine body. A fixed platform is fixedly connected to the top of the first hydraulic cylinder. Guide frames are slidably connected to the left and right outer peripheries of the fixed platform. Connecting arms are fixedly connected to the left and right sides of the fixed platform. A support frame is fixedly connected to the inner side of the connecting arms.

The rotating ring is rotatably connected to the inner side of the support frame. A second hydraulic cylinder is fixedly connected to the left side of the placement platform. A clamping plate is fixedly connected to the right side of the second hydraulic cylinder.
[0005] Preferably, the guide frame is fixedly connected to the top of the polishing machine body, and the rotating rod is rotatably connected to the inside of the fixed platform, so as to ensure the balance and stability of the fixed platform when it moves through the guide frame.
[0006] Preferably, the clamping plate is slidably connected inside the placement platform, and the top right side of the clamping plate is V-shaped, which facilitates the fixing of circular workpieces through the clamping plate.

[0010] Preferably, the rotating shaft is rotatably connected inside the fixed frame, and the grinding disc is located on the top of the placement platform, so that the grinding disc can be driven to work by the rotating shaft.
[0011] Compared with the prior art, this utility model provides a workpiece rotating base for a polishing machine, which has the following beneficial effects: 1. The workpiece rotating base of this polishing machine, through its placement mechanism, allows for the polishing of round workpieces. First, the workpiece is placed on top of the placement table. Second hydraulic cylinders and clamping plates, symmetrically distributed on both sides of the placement table, clamp and limit the workpiece from both sides, effectively preventing displacement or shaking during polishing. Simultaneously, the V-shaped design on the right side of the clamping plate further increases the contact area with the workpiece, enhancing stability and providing a solid foundation for polishing. This reduces polishing errors caused by workpiece displacement and improves product polishing quality. During polishing, the first hydraulic cylinder can adjust the height of the fixed table, the placement table above it, and the workpiece. Operators can flexibly adjust the workpiece height according to polishing needs, ensuring the top of the workpiece contacts the bottom of the polishing disc. When the fixed table moves, it slides within the guide frame, ensuring balance and stability during movement. The first servo motor drives the rotating rod to rotate the placement table, allowing the workpiece to rotate around the rotating rod, improving the uniformity and quality of polishing.
[0012] 2. The workpiece rotating base of this polishing machine, through the set polishing mechanism, when a round workpiece needs to be polished and the round workpiece is fixed by the clamp, the second servo motor drives the rotating shaft to drive the polishing disc to rotate at high speed, which can quickly polish the workpiece. The rotating shaft is rotatably connected inside the fixed frame to ensure the stability of the polishing disc rotation process and avoid the polishing effect being affected by the shaking of the polishing disc.

[0017] This utility model provides the following technical solution: Example 1 Please see Figure 1-7 This utility model provides a technical solution: a workpiece rotating base for a polishing machine, including a polishing machine body 1, a placement mechanism 2 provided on the top of the polishing machine body 1, and a polishing mechanism 3 provided on the rear side of the top of the polishing machine body 1; The placement mechanism 2 includes a first hydraulic cylinder 21, which is fixedly connected to the top of the polishing machine body 1. A fixed platform 22 is fixedly connected to the top of the first hydraulic cylinder 21. Guide frames 24 are slidably connected to the left and right outer sides of the fixed platform 22. Connecting arms 27 are fixedly connected to the left and right sides of the fixed platform 22. A support frame 28 is fixedly connected to the inner side of the connecting arms 27. A first servo motor 23 is fixedly connected to the bottom of the fixed platform 22. A rotating rod 25 is fixedly connected to the top of the first servo motor 23. A placement platform 26 is fixedly connected to the top of the rotating rod 25. A rotating ring 29 is fixedly connected to the bottom of the placement platform 26. The rotating ring 29 is rotatably connected to the inner side of the support frame 28. A second hydraulic cylinder 291 is fixedly connected to the left side of the placement platform 26. A clamping plate 292 is fixedly connected to the right side of the second hydraulic cylinder 291.
[0018] The guide frame 24 is fixedly connected to the top of the polishing machine body 1, and the rotating rod 25 is rotatably connected to the inside of the fixed table 22, so that the fixed table 22 can be balanced and stable when it moves through the guide frame 24.
[0019] The clamping plate 292 is slidably connected inside the placement platform 26, and the top right side of the clamping plate 292 is V-shaped, which makes it easy to fix the round workpiece through the clamping plate 292.
[0020] Two sets of the second hydraulic cylinder 291 and clamping plate 292 are provided and symmetrically distributed on the left and right sides of the placement platform 26, so that round workpieces of different sizes can be fixed by setting two sets.
[0021] Four sets of guide frames 24 are provided and symmetrically distributed on the left and right sides of the placement platform 26, which facilitates the balance of the fixed platform 22 when it moves through the guide frames 24.
[0022] Example 2 Please see Figure 1-7Furthermore, based on Embodiment 1, the polishing mechanism 3 includes a fixed frame 31, which is fixedly connected to the top rear side of the polishing machine body 1. A second servo motor 32 is fixedly connected to the top of the fixed frame 31, and a rotating shaft 33 is fixedly connected to the bottom of the second servo motor 32. A grinding disc 34 is fixedly connected to the bottom of the rotating shaft 33.
[0023] The rotating shaft 33 is rotatably connected inside the fixed frame 31, and the grinding disc 34 is located on the top of the placement platform 26, so that the grinding disc 34 can be driven to work by the rotating shaft 33.
[0024] In actual operation, when this device is used to polish a round workpiece, the workpiece is first placed on the top of the placement platform 26. The second hydraulic cylinder 291 drives the clamping plate 292 to move, so that the inner side of the clamping plate 292 contacts the outer side of the workpiece. The second hydraulic cylinder 291 and the clamping plate 292, which are symmetrically distributed on the left and right sides of the placement platform 26, can clamp and limit the workpiece from both sides, effectively preventing the workpiece from shifting or shaking due to force during the polishing process.

During the polishing process, the first hydraulic cylinder 21 can drive the fixed table 22 and the placement table 26 above it and the workpiece to adjust the height. The operator can flexibly adjust the height of the workpiece according to the polishing requirements so that the top of the workpiece contacts the bottom of the polishing disc 34. When the fixed table 22 moves, it will slide in the inner frame of the guide frame 24 to ensure balance and stability during movement. The second servo motor 32 drives the rotating shaft 33 to drive the polishing disc 34 to rotate at high speed, which can quickly polish the workpiece. The rotating shaft 33 is rotatably connected inside the fixed frame 31 to ensure the stability of the rotation process of the polishing disc 34 and avoid the polishing effect being affected by the shaking of the polishing disc 34. During the polishing process, the first servo motor 23 drives the rotating rod 25 to rotate the placement table 26, which enables the workpiece to rotate around the rotating rod 25 in a circle, improving the uniformity and quality of polishing. During the rotation, the angle of rotation cannot exceed 360 degrees, and the workpiece is rotated in this way. In this application, the first hydraulic cylinder 21, the second hydraulic cylinder 291, the first servo motor 23, and the second servo motor 32 need to be connected to the same PLC controller to ensure the coordinated operation of the equipment. The PLC controller is existing technology, and those skilled in the art are well aware of its operation method. Therefore, this application will not describe it in detail.
