Technical Field

[0001] The utility model relates to the technical field of polishing machines, in particular to a polishing machine capable of internal polishing. Background Art

[0002] Polishing machines, also known as grinding machines, are often used for mechanical grinding, polishing and waxing. They can grind off the rough parts on the surface of some objects to achieve the desired grinding effect of the product. After processing, cylindrical workpieces need to be polished on both the outer and inner surfaces. At this time, a polishing machine that can polish the inside of the cylindrical workpiece is needed.

[0003] According to a publicly disclosed polishing machine capable of internal polishing (publication number: CN216152060U), in the above application, a lifting device is provided, and the lifting device drives the polishing device to move up and down, so that the up and down movement of the polishing wheel in the polishing device can be freely controlled, and the polishing thickness is effectively controlled, thereby meeting the polishing requirements and improving the polishing effect.

[0004] However, in actual use, the above equipment can only process cylindrical workpieces with the same radius at a time because the polishing wheel is of fixed size. When workpieces of different specifications need to be processed, the polishing wheel needs to be replaced, which not only wastes time but also causes wear at the joints and affects the polishing accuracy. In view of this, we propose a polishing machine that can perform internal polishing. Utility Model Content

The cylindrical workpiece 3 can be clamped and fixed by starting the electric push rod, a cylindrical workpiece 3 is arranged inside the clamping mechanism 2, a fixing plate 5 is fixedly installed on the left end of the upper surface of the base 1, and an adjustable polishing mechanism 4 is arranged on the right side of the fixing plate 5.

[0028] The adjustable polishing mechanism 4 includes: a polishing motor 401, a mounting plate 402, a movable groove 406 and a polishing wheel 411. The polishing motor 401 is fixedly mounted on the right side surface of the fixing plate 5, and the mounting plate 402 is fixedly mounted on the upper surface of the base 1. A circular through hole 403 is opened on the right side surface of the mounting plate 402, and a bearing 404 is fixedly mounted inside the circular through hole 403. The bearing 404 can provide limiting support for the rotation of the rotating plate 405 and reduce the friction force when the rotating plate 405 rotates. The rotating plate 405 is fixedly mounted inside the bearing 404. The right side output shaft of the polishing motor 401 is fixedly connected to the left side surface of the rotating plate 405. When the polishing motor 401 is started, it can drive the rotating plate 405 to rotate.

[0029] The movable groove 406 is provided on the right side surface of the rotating plate 405, and an adjusting motor 407 is fixedly installed on the top inner wall surface of the movable groove 406, and a screw 408 is fixedly installed on the bottom output shaft of the adjusting motor 407. When the adjusting motor 407 is started, the screw 408 can be driven to rotate, and the outer side of the screw 408 is threadedly connected with a movable block 409, and the outer wall of the movable block 409 fits with the inner wall of the movable groove 406. When the screw 408 rotates, the movable block 409 can be driven to perform linear motion in the up and down directions under the limit inside the movable groove 406. A connecting shaft 410 is fixedly installed on the right side surface of the movable block 409, and when the movable block 409 is started, the connecting shaft 410 can be driven to perform synchronous motion, thereby adjusting the rotation radius of the polishing wheel 411, so that the polishing wheel 411 can polish the inside of the cylindrical workpiece 3 with different diameters, and the polishing wheel 411 is fixedly installed on the right end of the connecting shaft 410.

A filter 415 is fixedly installed inside the heat dissipation hole 414. The filter 415 can block dust and other debris to prevent it from entering the movable groove 406 and clogging the movable groove 406 after long-term accumulation.

[0032] In the utility model, when in use, the adjustment motor 407 is started, and the polishing wheel 411 is driven to perform linear motion in the up and down directions through the cooperation of the movable groove 406, the screw 408, the movable block 409 and the movable block 409, thereby adjusting the rotatable radius of the polishing wheel 411, so that the polishing wheel 411 can polish the inside of the cylindrical workpiece 3 with different internal radii, and then the polishing motor 401 is started, and the polishing wheel 411 is driven to rotate through the rotating plate 405 and the connecting shaft 410 to polish the inside of the cylindrical workpiece 3, and the interior of the bearing 404 and the movable groove 406 are sealed by the provided retaining ring 412 and the baffle 413 respectively, so as to prevent the debris generated during polishing from entering the bearing 404 and the movable groove 406 and affecting the rotation of the bearing 404 and the screw 408.
