Boom slot plate edge cutting device

Abstract

The invention discloses a cantilever crane trough plate edge cutting device which comprises a base, a cutting gun, an adjusting screw, a locking nut, a supporting piece, an adjusting roller and a fixed roller. The cutting gun is arranged on the base, the locking nut is also arranged on the base, the adjusting screw penetrates the locking nut and is in threaded fit with the locking nut, the supporting piece is arranged on the adjusting screw, the adjusting roller is arranged on the supporting piece, and the fixed roller is arranged on the base. During machining, the bottom face of a trough plate is clamped between the adjusting roller and the fixed roller. The cantilever crane trough plate edge cutting device is good in machining quality and stable, during work, it can be guaranteed that perpendicular distances between all points on cut station edges and the bottom face of the trough plate are basically unchanged (similar to shape cutting), the error values are always far smaller than a theory permissible error value, and therefore the consistency of the heights of all points of the two station edges of the trough plate relative to the bottom face in the length direction of the trough plate is guaranteed.

Description

technical field [0001] The invention relates to the field of processing and forming, in particular to an edge cutting device for a boom groove plate. Background technique [0002] The machining accuracy of the boom before welding the groove plate directly affects the quality of the boom after welding, as shown in the attached manual figure 1 As shown, the heights of the two sides 11 of the slot plate and the bottom surface 12 must be consistent at each point in the length direction of the slot plate, which is the premise guarantee for the quality of the jib after butt welding. [0003] At present, in order to solve this problem, mature large-scale professional production enterprises will purchase an edge planer of about 1 million yuan. However, for enterprises that process single-piece and small-batch booms, they do not have the conditions to purchase edge planers due to various reasons. Then it is manually cut segment by segment. Due to the error of the marking line, the...

However, for enterprises that process single-piece and small-batch booms, they do not have the conditions to purchase edge planers due to various reasons. Then manually cut line by line

Due to the error of the marking line, the thickness of the stone pencil line, the change of the light, the pros and cons of the operator's technology, etc., the edge of the station after cutting is uneven, and the size is large or small. Unsatisfactory, as a result, the welding seam of the welded boom is uneven, and the overall distortion is more common, often resulting in defective or even waste products
