Machining tool for bucket wheel body of stacker-reclaimer

Abstract

The invention discloses a stacker-reclaimer bucket wheel body machining tool, a bucket wheel body comprises a shaft sleeve, the machining tool comprises a boring machine body, and the boring machine body comprises a boring rod; the outer circle machining device comprises a first outer supporting body and a second outer supporting body, and a boring cutter is arranged on the first outer supporting body; the second outer supporting body and the first outer supporting body are locked and fixed on the boring rod on the outer side of the shaft sleeve after being in butt joint; the inner supporting device is arranged in the inner hole of the shaft sleeve, is used for supporting the shaft sleeve, and comprises two inner supporting bodies which are locked and fixed on the boring rod after being butted and matched; and the supporting part is arranged in the inner supporting body, part of the supporting part extends out of the inner supporting body, and the position of the supporting part relative to the inner supporting body is adjustable. According to the machining device for the bucket wheel body of the stacker-reclaimer, the bucket wheel body is prevented from being transferred back and forth, the bucket wheel body is directly machined on site, the production cost is reduced, and the transportation risk is avoided.

Description

technical field [0001] The invention belongs to the technical field of loading and unloading machinery, and in particular relates to a processing device for a shaft sleeve of a bucket wheel body of a stacker and reclaimer. Background technique [0002] The central shaft sleeve of the bucket wheel body of the 12000 stacker-reclaimer adopts a new structure. It is not only necessary to ensure the coaxiality of the shaft sleeve and the inner holes at both ends, but also to ensure the coaxiality of the inner hole at one end and the outer circle. The outer body of the bucket wheel is welded with steel, and the diameter of the outer circle is super large, reaching more than 7 meters. The bushing at the center is fixed by welding, because the shape and position of the center bushing will be deformed during welding , so it cannot be adopted, the method of first processing the shaft sleeve and then welding the central shaft sleeve to the center of the bucket wheel body. Instead, it i...

AI Technical Summary

Problems solved by technology

[0004] Because the 12000 stacker-reclaimer is a large-scale special equipment, and there is only one bucket wheel body on each equipment, it belongs to single-piece small-batch production in terms of processing batches, and cannot be mass-produced according to the mass production process

The processing equipment needs to be processed with a super-large, floor-standing vertical lathe, resulting in high production costs for a single piece

[0005] Because the volume of the bucket wheel is too large, the company's existing mechanical processing equipment cannot be clamped and processed. Such a large workpiece makes it impossible to process the bucket wheel inside the company. If processing is required, it needs to be transported to other companies. Co-processing

[0006] The diameter of the bucket wheel body is more than 7 meters, and the volume is too large. It is difficult to transport by land. If outsourcing processing is required, it needs to be transported to the processing factory by an ultra-wide vehicle for processing. There is a risk of transporting super-large workpieces, and the transportation and processing costs are high. , leading to high production costs

The production schedule is difficult to guarantee and cannot meet the production demand

[0007] To sum up, the bucket wheel body of the 12000 stacker-reclaimer cannot be processed through the existing mechanical processing equipment, and it is transported by land to the outsourcing unit for processing. There is a large transportation risk, and the transportation and processing costs are high, and the production period cannot be completed. be satisfied
