Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheel guiding of a polishing machine, in particular to a grinding wheel seat guide wheel device of a vibration polishing machine. Background Art

[0002] Most polishing machine grinding wheels are fixedly installed on the grinding wheel seat in the upper and lower positions. When the sanding belt is in contact with the surface of the fixed block during rotation, there is direct friction between the sanding belt and the fixed block. With direct friction, the resistance between the fixed block and the sanding belt is very large. During the normal operation of the sanding belt, the sanding belt is subject to great resistance and is prone to being broken, making it impossible to use the sanding belt normally. At the same time, the direct friction between the sanding belt and the fixed block will also increase the wear of the fixed block and change the shape of the fixed block, so that the fixed block cannot be used normally. In order to reduce the possibility of the sanding belt being broken and reduce the degree of wear of the fixed block, the present invention provides a grinding wheel seat guide wheel device for a dynamic polishing machine.

[0021] Example 1

[0022] See also Figure 1-Figure 3 As shown, the present embodiment provides a grinding wheel seat guide wheel device of a vibration polishing machine, comprising a grinding wheel seat 1, a grinding wheel 2 is rotatably arranged on the grinding wheel seat 1, a guiding assembly is arranged between the grinding wheel seat 1 and the grinding wheel 2, a sanding belt 6 is sleeved and connected between the guiding assembly and the grinding wheel 2, when the sanding belt 6 contacts and rubs with an object, the grinding wheel 2 is driven to rotate on the grinding wheel seat 1 through the friction between the sanding belt 6 and the grinding wheel 2, and the sanding belt 6 is driven to rotate when the grinding wheel 2 rotates, and the guiding assembly guides the rotating sanding belt 6 to make the sanding belt 6 circulate and rotate on the grinding wheel seat 1, and guides the sanding belt 6 through the guiding assembly to make the sanding belt 6 and the grinding wheel 2 rotate and rub, thereby reducing the resistance generated by the friction between the grinding wheel 2 and the sanding belt 6, and avoiding the sanding belt 6 from being pulled apart during operation, while reducing the friction of the sanding belt 6 on the grinding wheel 2, reducing the loss of the grinding wheel 2, and extending the service life of the grinding wheel 2.

[0023] A plurality of friction strips 21 are fixedly connected to the side wall of the grinding wheel 2 in a circular array along the axis of the grinding wheel 2, and a friction convex strip 22 fixed to the side wall of the grinding wheel 2 is arranged between every two friction strips 21, and a plurality of cone heads are arranged on the friction convex strip 22. The friction strips 21 and the cone heads are in contact with the inner side wall of the sanding belt 6. By making one side of the friction strips 21 and the friction convex strips 22 contact with the side wall of the sanding belt 6, the friction between the sanding belt 6 and the grinding wheel 2 is increased, so that the sanding belt 6 can drive the grinding wheel 2 to rotate, thereby avoiding sliding friction between the grinding wheel 2 and the sanding belt 6.

[0024] The grinding wheel seat 1 includes a vertical plate 11, and clamping plates 12 are fixed at the upper and lower ends of the vertical plate 11. The two clamping plates 12 extend toward one side of the vertical plate 11. A cylinder connecting rod 13 is fixed on the other side of the vertical plate 11. The cylinder connecting rod 13 is connected to an external hydraulic rod. At the same time, a directional guide rod 14 fixed to the vertical plate 11 is arranged on the lower side of the cylinder connecting rod 13. The directional guide rod 14 is slidably connected to one end of the hydraulic rod. The sliding connection between the directional guide rod 14 and the hydraulic rod is used to limit the position of the grinding wheel seat 1, avoid shaking of the grinding wheel seat 1 during operation, and improve the stability of the use of the grinding wheel seat 1.

[0025] The guide assembly includes two side guides and a middle guide between the two side guides. The guide assembly is arranged on the side of the vertical plate 11, and the middle guide is arranged on the side of the vertical plate 11 away from the cylinder connecting rod 13. The side guide and the middle guide both include a guide wheel sleeve 5. The guide wheel sleeve 5 is rotatably arranged between the two clamping plates 12 through the guide wheel shaft 4. The grinding wheel 2 is rotatably arranged between the two clamping plates 12 through the fixing bolt 3. The grinding wheel 2 rotates around the fixing bolt 3, and the guide wheel sleeve 5 rotates around the guide wheel shaft 4. At the same time, the grinding belt 6 is sleeved inside the grinding wheel 2 and the guide wheel sleeves 5 on the two side guides, so that the grinding belt 6 is supported into a triangle. At the same time, the guide wheel sleeve 5 on the middle guide blocks the grinding belt 6, so that the position of the grinding belt 6 close to the middle guide is close to the grinding wheel 2, so that the grinding belt 6 is bent into a rhombus.

[0026] When the grinding wheel and the object to be polished come into contact, the grinding wheel seat 1 is driven up and down to move so that the sanding belt 6 and the object are rubbed. In the process of the sanding belt 6 rubbing the object, the grinding wheel 2 drives the sanding belt 6 to rotate. When the grinding wheel 2 rotates, the sliding friction between the grinding wheel 2 and the sanding belt 6 is changed to rotational friction, thereby reducing the friction between the grinding wheel 2 and the sanding belt 6 and avoiding the sanding belt 6 to rub the grinding wheel 2. At the same time, the friction strip 21 and the friction convex strip 22 are in contact with the sanding belt 6, thereby improving the stability of the connection between the grinding wheel 2 and the sanding belt 6 and reducing the possibility of sliding friction between the grinding wheel 2 and the sanding belt 6, thereby extending the service life of the grinding wheel 2. At the same time, by performing rotational friction between the grinding wheel 2 and the sanding belt 6, the sanding belt 6 is prevented from breaking due to force when polishing the object, thereby extending the service life of the sanding belt 6.

[0027] In order to ensure that the sanding belt 6 can effectively grind the object, a gap is left between the guide wheel sleeve 5 on the middle guide and the grinding wheel 2. When the sanding belt 6 is arranged between the grinding wheel 2 and the guide wheel sleeve 5 on the middle guide, one side of the sanding belt 6 contacts the side wall of the grinding wheel 2, and the sanding belt 6 contacts the other side of the grinding wheel 2, thereby increasing the force of the grinding wheel 2 to drive the sanding belt 6 to rotate, so that the sanding belt 6 can grind the object during the rotation process, thereby ensuring the normal operation of the sanding belt 6 and ensuring the effect of the sanding belt 6 on grinding the object while extending the service life of the sanding belt 6.

[0028] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
