Crankshaft journal polishing device

Abstract

The invention relates to a crankshaft journal polishing device which comprises a clamping and polishing mechanism, a supporting, hanging and swinging mechanism and an abrasive belt conveying mechanism, wherein the clamping and polishing mechanism comprises an upper polishing arm and a lower polishing arm; the rear parts of the upper and lower polishing arms are connected with a clamping air cylinder; an upper pressing block and a lower pressing block are mounted at the front parts of the upper and lower polishing arms; an upper hinged support and a lower hinged support are mounted in the middles of the upper and lower polishing arms and are connected in series through a pin shaft; the supporting, hanging and swinging mechanism comprises a carriage, an upright column, a hanging plate and tension springs; a sleeve and a rotating shaft are horizontally mounted at the top end of the upright column; the lower part of the hanging plate is connected with the upper polishing arm; the upper part of the hanging plate is mounted on the rotating shaft; the two tension springs are hung between a top plate and the middle of the upper polishing arm through a pull rod and hanging columns; and the abrasive belt conveying mechanism comprises a roller seat, an abrasive belt roll, a delivery roller support, a delivery roller, a pull roller support and a pull roller. An abrasive belt is pulled out along the delivery roller and the pull roller from the abrasive belt roll, the upper and lower pressing blocks directly face a to-be-polished crankshaft journal, the clamping air cylinder is started to make a piston rod to extend out to clamp the crankshaft journal, a machine tool drives a crankshaft to rotate, and the crankshaft journal is polished by the abrasive belt between the upper pressing block and the crankshaft journal. The crankshaft journal polishing device is reasonable in structure, simple to manufacture, convenient to operate and suitable for polishing of the crankshaft journal.

Description

technical field [0001] The invention relates to a crankshaft diameter polishing device mechanism, in particular to a simple crankshaft journal polishing device. Background technique [0002] We know that engine crankshaft parts, due to the working characteristics of their parts, need to polish the surface roughness of the journal, and must ensure the shape and position tolerance requirements such as cylindricity. The polishing machine used can automatically complete the polishing of all journals at one time, the effect is better, and it is also suitable for large batch production, but the price is expensive. Using the device for repaired or trial-manufactured crankshafts will cause large waste or high production costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a crankshaft journal polishing device with reasonable structure, simple manufacture, ...
