Portable field metallographic automatic grinding and polishing device and using method thereof

Abstract

The invention discloses a portable field metallographic automatic grinding and polishing device and a using method thereof. The automatic grinding and polishing device comprises an H-shaped support, aclamping device, a horizontal reciprocating motion device and a rotary motion device. The using method comprises the following steps that 1, to-be-ground and polished pipes are fixed at the bottoms of the two metal rods of the H-shaped support through the clamping device; 2, selected grinding pieces are fixed at the bottom of the rotary motion device, and the grinding pieces are guaranteed to bein contact with the to-be-ground and polished pipes; 3, the rotary motion device and the horizontal reciprocating motion device begin to work, and the grinding pieces begin to polish the to-be-groundand polished pipes; and 4, after one-stage grinding is completed, the device is closed, the grinding pieces are replaced, and the above steps are repeated until the surface of the to-be-ground and polished pipes is polished to be bright. The automatic grinding and polishing device can be fixed on the surface of an in-service pipe to work, and is suitable for workpieces with any height and position, the labor intensity of experimenters can be effectively reduced, the working efficiency is improved, potential safety hazards are reduced, and the grinding and polishing quality is further ensured.

Description

technical field [0001] The invention relates to a metallographic grinding and polishing device, in particular to a portable on-site metallographic automatic grinding and polishing device and a using method thereof. Background technique [0002] Coal-fired power plants, oil refineries, etc. contain metal pipe fittings of various specifications and materials. These metal pipe fittings usually work under high temperature and pressure conditions, and face the danger of long-term contact with the corrosive medium in the pipe. These harsh service environments It will cause the metal materials to gradually age and reduce their performance during the service process, which will bury hidden dangers for the safe operation of the equipment. Therefore, it is very necessary to regularly analyze the structure of metal pipe fittings operating in harsh environments and replace severely aged pipe fittings in time. [0003] In order not to damage the integrity of the equipment, the boiler tu...

AI Technical Summary

Problems solved by technology

Metallographic inspection includes a lot of grinding and polishing work, and the existing automatic grinding and polishing equipment on the market is mainly for laboratory use. Phase grinding and polishing requirements; therefore, most of the current on-site metallography uses angle grinders, pistol drills and other handheld equipment for grinding and polishing

However, the efficiency of manual hand-held grinding is low and the labor intensity is high. For some pipe fittings whose positions are too high, too low, or too biased, manual grinding has certain safety risks, and has certain impacts on the progress of inspection work and the quality of grinding and polishing. Influenced by the degree of grinding, the lack of polishing will even affect the accuracy of the test results
