Description

Technical Field

[0001] The utility model relates to the technical field of polishing, in particular to a protective device for polishing a round rod. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and flat surface. It is a modification process on the surface of a workpiece using polishing tools and abrasive particles or other polishing media. Polishing cannot improve the dimensional accuracy or geometric shape accuracy of the workpiece, but is intended to obtain a smooth surface or mirror gloss. Sometimes it is also used to eliminate gloss (matte). Usually, a polishing wheel is used as a polishing tool. The polishing wheel is generally made of multiple layers of canvas, felt or leather, clamped on both sides with metal circular plates, and its wheel rim is coated with a polishing agent uniformly mixed with micro-powder abrasives and grease. There is an existing patent for a polishing round rod protective device, patent publication number CN103624686A, which includes a protective cylinder, the protective cylinder is a hollow cylinder, and the inner and outer surfaces are parallel to each other with respect to the center. The protective cylinder lies horizontally on a bracket, and a semicircular groove is opened in the middle of the upper surface of the bracket. The diameter of the semicircular groove is the same as the outer diameter of the protective cylinder. A fastener is provided on the upper surface of the bracket, and the fastener fixes the protective cylinder in the semicircular groove through bolts and nuts. The advantages of the present invention are: the device has a simple structure and is easy to operate. When in use, one end of the polishing rod is placed in the protective cylinder. When the rod shakes or separates from the polishing wheel, the protective cylinder can well limit the movement of the rod, thereby preventing the rod from harming the operator.
