A double compensation device for abrasive belt polishing

[0020] refer to Figure 1~Figure 7 , a double compensation device for abrasive belt polishing, including a frame 1, the frame 1 is provided with an abrasive belt driving mechanism 2 and a polishing head mechanism 3, and the front end of the frame 1 is provided with a sliding seat 4 that can slide back and forth , the sliding seat 4 is connected with a first power mechanism 8 for maintaining its forward pressure, the upper end surface of the sliding seat 4 is provided with a rotating shaft 401, and the adjusting frame 5 is hinged on the rotating shaft 401, and the adjusting frame 5 The first end portion 501 of the front end and the second end portion 502 of the rear end are provided, the first end portion 501 is connected with the polishing head mechanism 3, and the second end portion 502 is connected with a second end portion for pushing the adjustment frame 5 to rotate. The power mechanism 6, wherein preferably, the first power mechanism 8 and the second power mechanism 6 use cylinders, of course, servo motors can also be used to drive the sliding seat 4 to move through screw rods or gears and racks. With the above structure, when the abrasive belt 5 on the side of the polishing head mechanism 3 is used for polishing, the second power mechanism 6 drives the polishing head mechanism 3 (that is, the polishing position of the abrasive belt 5 ) to rotate by pushing the adjustment frame 5 to keep the polishing head mechanism 3 The pressure of the side to the workpiece, especially the use of the cylinder as the second power mechanism 6, due to the characteristics of the air pressure, the second power mechanism 6 will force the abrasive belt 5 to be pressed tightly on the workpiece, and automatically maintain the polishing head mechanism 3 at the set Under the state of lateral pressure, the compensation is performed in real time, the response is fast, the polishing force is guaranteed to be stable, and the polishing quality is improved. The second power mechanism 6 directly acts on the polishing head mechanism 3, and the structure it promotes is light and handy, so the compensation action has a fast response speed and can be used. Greatly improve the polishing quality; when the abrasive belt 5 on the front of the polishing head mechanism 3 is used for polishing, the first power mechanism 8 pushes the sliding seat 4 to keep the abrasive belt 5 in the set forward pressure state and compensates in real time, preferably the first The power mechanism 8 adopts a cylinder, which realizes instant compensation by using the characteristics of air pressure. The combination of two compensations can meet the needs of polishing compensation in all directions, and the polishing effect is stable and reliable.

[0021] In this embodiment, preferably, the frame 1 is provided with a linear slide rail 101, and other sliding components such as optical shafts, linear bearings, etc. can also be used, as long as the sliding seat 4 is linearly slidable. The slide seat 4 is provided with a slide block 402 matching the linear slide rail 101 . The sliding seat 4 is installed on the linear sliding rail 101 through the sliding block 402, and the sliding seat 4 can slide along the linear sliding rail 101. The structure is simple and durable, the cost is low, and the maintenance is convenient.

[0022] In this embodiment, preferably, a bearing is provided between the rotating shaft 401 and the adjustment frame 5 . Since the adjustment frame 5 needs to rotate frequently, the use of bearings can ensure that the adjustment frame 5 rotates smoothly, is reliable and durable.

[0023] In this embodiment, preferably, the polishing head mechanism 3 is provided with a clamping plate 301, the clamping plate 301 is L-shaped, its long side extends to the end close to the polishing head mechanism 3, and its corner is connected to the end of the polishing head mechanism 3. The first end 501 is hinged, and its short side is connected with a third power mechanism 7 to push the clamping plate 301 to rotate. The third power mechanism 7 preferably adopts an air cylinder, and the adjustment frame 5 is also provided with a third end 503. The third power mechanism 7 is hinged to the third end portion 503 . The clamping plate 301 presses the abrasive belt 5 on the polishing head mechanism 3, and also has the function of preventing deviation. The third power mechanism 7 is used to push the clamping plate 301 to rotate, which is convenient for real-time adjustment.

[0024] The above is only a preferred embodiment of the present invention, but the present invention is not limited to the above-mentioned embodiments, as long as it achieves the technical effect of the present invention by any same or similar means, it should fall within the protection scope of the present invention .
