Elbow polishing machine

Abstract

The invention relates to a device for polishing the inner wall of an elbow, in particular to an elbow polishing machine and mainly solves the problem that the existing device cannot polish the inner wall of the elbow. The elbow polishing machine comprises a machine frame, a left crankshaft, an idler shaft and a right crankshaft are installed on the machine frame side by side, a left crankshaft gear and a right crankshaft gear are respectively meshed with an idle pulley, the inner end of the left crankshaft gear and the inner end of the right crankshaft gear are respectively and rotatably connected with a motor arc-shaped support, a motor is installed on the end portion of the motor arc-shaped support, a polishing wheel is arranged on a motor shaft, a crank driving motor is further arranged on the machine frame, and a crank driving motor gear is meshed with the left crankshaft gear. A rotation arm rotating shaft is further arranged on the machine frame and rotatably connected with the machine frame, an elbow rotation arm gear is arranged on the rotation arm rotating shaft is meshed with an elbow driving motor gear of an elbow driving motor installed on the machine frame, and the elbow rotation arm is fixed on the rotation arm rotating shaft. The elbow polishing machine has the advantages of being even in polishing and good in quality.

Description

Technical field: [0001] The invention relates to a device for polishing the inner wall of an elbow. Background technique: [0002] Due to the limitation of the shape of the elbow, in the current production, the inner wall of the elbow cannot be polished with a polishing wheel, and only sandblasting or corrosion can be used to improve the smoothness of the inner wall of the elbow. The disadvantages are uneven polishing, poor polishing quality, and high speed. Slow and low efficacy. Invention content: [0003] The technical problem to be solved by the present invention is to provide an elbow polishing machine with uniform polishing, good polishing quality and high speed when polishing the inner wall of the elbow. [0004] Above-mentioned purpose is achieved like this: it comprises frame, and left crankshaft, idler shaft, right crankshaft are installed side by side successively on the frame, and all are connected with frame rotation, left crankshaft gear and right crankshaft...
