Manufacturing method for supporting seat of hydraulic cylinder of grate cooler

Abstract

The invention discloses a manufacturing method for a supporting seat of a hydraulic cylinder of a grate cooler. The manufacturing method comprises the following steps of: firstly, roughly milling a bottom riser of the supporting seat of the hydraulic cylinder in a horizontal milling mode, keeping machining allowance, and switching to an HMC630e small numerical-control processing center after linearly milling one side surface as datum reference; carrying out tool alignment by utilizing a dial gauge before processing parts, and taking the processed side surface as datum reference; symmetrically mounting and clamping two parts at the two sides of a tool clamp I to carry out processing on a bottom plane, a positioning key slot, a bolt hole and a dowel pin hole; taking down the processed parts and symmetrically clamping the parts at the other two sides of the tool clamp I, and processing shaft holes in double lugs and outer side surfaces after positioning; and finally, processing slot holes in the double lugs. According to the manufacturing method disclosed by the invention, existing production process flow is optimized to form a novel production process, so that a product qualification rate is increased, labor intensity is reduced, batched and small-assembly-line operation is realized, and assembly requirements of a grate cooler production line are met.

Description

technical field [0001] The invention relates to a method for manufacturing parts, in particular to a method for manufacturing a hydraulic cylinder support of a grate cooler, and belongs to the technical field of hydraulic cylinder support manufacturing. Background technique [0002] The hydraulic cylinder support is a part of the hydraulic transmission mechanism of the grate cooler. The feasibility, rationality and advancement of its processing technology will directly affect the quality, production cost, performance and life of the whole part. The technical requirements of the existing hydraulic cylinder support are as follows: figure 1 and figure 2 As shown, the material of the part is cast steel ZG270-500, and the weight is 27.25kg; the shape of the part is irregular, the nominal size of the outer shape is 250*200*140, the machining allowance on one side is about 6mm, and the tolerance of the intermediate shaft hole is required to be 0 -+0.03mm, the smoothness requirem...

Problems solved by technology

[0004] 1. When machining parts on the T611 boring machine, the clamping accuracy in the clamping and correction process is low. When machining the Φ45 shaft hole and the bottom plane positioning keyway, it is easy to produce processing errors caused by datum transformation; processing on the small vertical milling machine X52K When the inner notch at the ear of the hydraulic cylinder support is clamped with a vise, the traditional end mill is processed in one piece, resulting in inconsistent groove width and low product qualification rate;

[0005] 2. There are many holes that need to be drilled on the hydraulic cylinder support, the relationship between the holes is not easy to confirm, the center of the hole is difficult to locate, and the center distance between the holes cannot meet the requirements of the drawing; Bottom plane holes are processed in this way, and the drill bit is easy to shake and deviate from the center line during the processing, so that the symmetry and verticality of the processed holes do not meet the technical requirements of the drawings, resulting in a low product qualification rate;

[0006] 3. When processing the hydraulic cylinder support, it is clamped in a vise and the dial indicator is aligned. It takes a long time to process a single piece, the labor intensity is high, and the efficiency is low. It is not suitable for the processing of batch parts and cannot meet the assembly requirements. And the production uneconomical cost
