Description

Technical Field

[0001] This utility model relates to the field of polishing technology, and in particular to a polishing mechanism and a polishing machine. Background Technology

[0002] The polishing mechanism, as the core of the polishing machine, performs fine grinding on the workpiece surface using a high-speed rotating abrasive belt. In existing technologies, some polishing mechanisms include a compensation component that drives the working wheel. This component adjusts the tension of the abrasive belt and the contact state between the working wheel and the workpiece surface, thus mitigating the impact of abrasive belt wear and load fluctuations on the polishing quality. However, through in-depth research on existing polishing mechanisms, the inventors discovered that, limited by the length of the abrasive belt, the existing compensation components can only drive the working wheel to move a small range. Therefore, the degree of movement compensation is limited, making them unsuitable for polishing workpieces with complex curved surfaces or irregular shapes. Utility Model Content

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0032] In the description of this utility model, the use of terms such as first, second, third, fourth, and fifth is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] In this utility model, unless otherwise explicitly defined, the terms "setting," "installing," and "connecting" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a fixed connection, a detachable connection, or an integral molding; they can refer to a mechanical connection; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] Reference Figures 1 to 3 This utility model discloses a polishing mechanism, which includes a frame 100 and a polishing assembly 200. The polishing assembly 200 includes an abrasive belt 210, a first compensation assembly 220, and a first drive member 230. The first compensation assembly 220 and the first drive member 230 are both mounted on the frame 100. The first drive member 230 has a rotatable first drive wheel 231. The first compensation assembly 220 has a rotatable working wheel 310 and a rotatable tension wheel 320. The first drive wheel 231, the working wheel 310, and the tension wheel 320 are arranged in a triangular three-point configuration. The abrasive belt 210 is sleeved on the first drive wheel 231, the working wheel 310, and the tension wheel 320. The first drive member 230 can drive the first drive wheel 231 to rotate, thereby driving the abrasive belt 210 to rotate. The first compensation assembly 220 can drive the working wheel 310 and the tension wheel 320 to move, thereby adjusting the position of the working wheel 310 while maintaining a preset tension on the abrasive belt 210.

[0036] Understandably, the compensation components of a traditional polishing mechanism only drive the work wheel 310 to move. Therefore, due to the kinematic constraints of the closed-loop system of the sanding belt 210, the range of motion that the work wheel 310 can move is relatively small.

[0037] Through the above structure, on the one hand, by driving the working wheel 310 and the tension wheel 320 to move in coordination through the first compensation component 220, the segment length of the sanding belt 210 can be dynamically released or absorbed. This allows the movement range of the working wheel 310 to be expanded while maintaining the preset tension of the sanding belt 210, thereby adapting to the polishing needs of complex curved or irregularly shaped workpieces and reducing the problem of polishing blind spots caused by the limited movement of the working wheel 310. On the other hand, the coordinated adjustment mechanism of the working wheel 310 and the tension wheel 320 can ensure the tension stability of the sanding belt 210 by balancing the changes in the segment length of the sanding belt 210 in real time, significantly improving the uniformity of polishing and reducing the problem of slippage, breakage, or overcutting of the workpiece surface caused by sudden changes in tension.

[0038] In this embodiment, refer to Figure 2The first compensation component 220 includes a second drive member 221 and a third drive member 222. The second drive member 221 is mounted on the frame 100 and is connected to a first frame 221A. The first frame 221A is rotatably provided with a working wheel 310. The third drive member 222 is mounted on the frame 100 and is connected to a second frame 222A. The second frame 222A is rotatably provided with a tension wheel 320. The second drive member 221 and the third drive member 222 can respectively drive the working wheel 310 and the tension wheel 320 to move. The second drive member 221 is configured as a cylinder, hydraulic cylinder, etc.; the third drive member 222 is configured as a cylinder, hydraulic cylinder, etc.

[0039] To improve the stability of the first 221A and the second 222A during movement, and to improve the stability of the working wheel 310 and the tension wheel 320 during movement, refer to Figure 2 The first 221A and the second 222A are both slidably mounted on the frame 100 via the slider rail assembly 400.

[0040] In some embodiments, the first compensation component 220 includes a spring, a fourth drive member, and a third frame. One end of the spring and the fourth drive member are both disposed on the frame 100. The third frame is slidably disposed on the frame 100 and connected to the other end of the spring. The fourth drive member is connected to the fourth frame. The working wheel 310 is rotatably disposed on the third frame, and the tension wheel 320 is rotatably disposed on the fourth frame. The fourth drive member can drive the tension wheel 320 to move so that the corresponding working wheel 310 can be driven to move by the sanding belt 210 or the spring. The fourth drive member is configured as a cylinder, hydraulic cylinder, etc.

[0041] Reference Figure 2 The above embodiment can be understood as follows: the third drive member 222 is regarded as the fourth drive member, the second frame 222A is regarded as the fourth frame, the first frame 221A is regarded as the third frame, and the second drive member 221 is replaced by a spring member. Therefore, when the fourth drive member drives the tension wheel 320 to move upward, the tension wheel 320 pushes the sanding belt 210, causing the sanding belt 210 to drive the working wheel 310 to move upward, and the spring member is compressed; when the fourth drive member drives the tension wheel 320 to move downward, the sanding belt 210 loosens, the spring member returns and drives the working wheel 310 to move downward to press against the sanding belt 210.

[0042] In some embodiments, the first compensation component 220 includes a spring, a fourth drive member, and a third frame. One end of the spring and the fourth drive member are both disposed on the frame 100. The third frame is slidably disposed on the frame 100 and connected to the other end of the spring. The fourth drive member is connected to the fourth frame. The tension wheel 320 is rotatably disposed on the third frame, and the working wheel 310 is rotatably disposed on the fourth frame. The fourth drive member can drive the working wheel 310 to move so that the corresponding tension wheel 320 can be driven to move by the sanding belt 210 or the spring. The fourth drive member is configured as a cylinder, hydraulic cylinder, etc.

[0043] Reference Figure 2 The above embodiment can be understood as follows: the second drive member 221 is regarded as the fourth drive member, the first frame 221A is regarded as the fourth frame, the second frame 222A is regarded as the third frame, and the third drive member 222 is replaced with a spring member. Therefore, when the fourth drive member drives the working wheel 310 to move downward, the working wheel 310 pushes the sanding belt 210, causing the sanding belt 210 to drive the tension wheel 320 to move downward, and the spring member is compressed; when the fourth drive member drives the working wheel 310 to move upward, the sanding belt 210 loosens, the spring member returns and drives the tension wheel 320 to move upward and tighten against the sanding belt 210.

[0044] In this embodiment, refer to Figure 2 The polishing assembly 200 also includes a correction assembly 240 disposed on the frame 100. The correction assembly 240 is provided with a rotatable correction wheel 330. The sanding belt 210 is sleeved on the first drive wheel 231, the working wheel 310, the tension wheel 320 and the correction wheel 330. The correction assembly 240 can drive the correction wheel 330 to swing at a preset angle to prevent the sanding belt 210 on the first drive wheel 231, the working wheel 310, the tension wheel 320 and the correction wheel 330 from deviating and falling off.

[0045] The correction assembly 240 includes a fifth frame 241 and a reducer 242. The reducer 242 is located on the frame 100. The fifth frame 241 is connected to the output end of the reducer 242. The correction wheel 330 is rotatably located on the fifth frame 241. The input end of the reducer 242 can rotate to drive the fifth frame 241 to rotate and cause the correction wheel 330 to swing.

[0046] To facilitate the rotation of the input end of the reducer 242, refer to Figure 2 The input end of the reducer 242 is equipped with a handwheel 600.

[0047] In this embodiment, refer to Figure 1 and Figure 3The polishing assembly 200 also includes a second compensation assembly 250 disposed on the frame 100. The second compensation assembly 250 is provided with a rotatable rotating shaft assembly 252A, on which a polishing wheel 340 is sleeved. The first driving member 230 is provided with a second driving wheel 232. The rotating shaft assembly 252A and the second driving wheel 232 are sleeved with a transmission belt 500. The first driving member 230 can drive the rotating shaft assembly 252A to rotate so as to drive the polishing wheel 340 to rotate. The second compensation assembly 250 can drive the polishing wheel 340 to move. The first driving member 230 is configured as a dual-axis motor. The two output shafts of the first driving member 230 are respectively sleeved with the first driving wheel 231 and the second driving wheel 232.

[0048] It is understood that the rotating shaft assembly 252A includes a rotating shaft and a rotating wheel slidably sleeved thereon. The rotating shaft is rotatably mounted on the second compensation component 250. The rotating wheel and the second drive wheel 232 are sleeved with a transmission belt 500. The rotating shaft is fixedly sleeved with a polishing wheel 340. The first drive component 230 can drive the rotating wheel to rotate, so as to drive the rotating shaft to rotate and drive the polishing wheel 340 to rotate.

[0049] Through the above structure, on the one hand, the polishing mechanism of this application integrates the polishing system of the abrasive belt 210 and the polishing system of the polishing wheel 340 (such as a nylon wheel), which can significantly improve the adaptability, efficiency and processing quality of the polishing mechanism through process complementarity and functional synergy; on the other hand, the first drive wheel 231 and the second drive wheel 232 can be driven by a first drive component 230. In other words, the first drive wheel 231 and the second drive wheel 232 share a power source, which can reduce the number of independent motors and save the cost of the polishing mechanism; furthermore, based on the design of the above-mentioned rotating shaft assembly 252A, the second compensation component 250 can drive the polishing wheel 340 to move, so as to compensate for the wear of the polishing wheel 340 and ensure the contact state between the polishing wheel 340 and the workpiece.
