Embodiment Construction

[0014] The double eccentric flange processing method of the present invention comprises the following steps:

[0015] The first step is CNC cutting. On the CNC cutting machine, the steel plate with a thickness of 30mm is laid out, and the outer diameter of the cut material is 190mm and the diameter of the inner hole is 80mm;

[0016] The second step is turning, clamping the upper end surface on the C616 lathe, turning the lower end surface, turning the outer circle to a diameter of 184mm, turning the inner hole to a diameter of 84mm, clamping the lower end surface, and turning the upper end surface to ensure a thickness of 27mm;

[0017] The third step is to mark the line. On the fitter's table, clamp it on the dividing head and use the vernier height gauge to draw the center line of the flange symmetrically on the outer circle;

[0018] The fourth step is to count the cars. On the CK630 CNC lathe, clamp a three-jaw chuck with the reverse jaw of the four-jaw chuck. First use t...

Abstract

The invention relates to the field of machining, in particular to a double eccentric flange machining method which includes the steps: performing numerical control cutting and laying out a 30mm thick steel plate on a numerical control cutting machine; clamping an upper end face and turning a lower end face on a C616 lathe, turning an external circle to reach the diameter of 184mm, turning an inner hole to reach the diameter of 84mm, clamping the lower end face, turning the upper end face and ensuring the thickness of 27mm; symmetrically marking the center line of a flange on the external circle by a vernier height gauge clamped on an indexing head of a vice bench; inversely clamping a three-jaw chuck by a four-jaw chuck on a CK630 numerical control lathe, adjusting eccentricity 3mm to be qualified by a dial indicator, making marker lines, clamping the flange on the three-jaw chuck, aligning the marked lines to the center line, turning the lower end face and then turning a groove and an inner hole with the diameter of 100mm. The external circle diameter of a cut blank is 190mm, and the internal bore diameter of the cut blank is 80mm. The double eccentric flange machining method is simple in operation and convenient in machining, machining quality and machining precision of workpieces can be ensured, production efficiency is improved, and production cost is reduced.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a method for processing double eccentric flanges. Background technique [0002] When drawing up the process route, the degree of process concentration or decentralization mainly depends on the production scale, the structural characteristics and technical requirements of the parts, and sometimes the consistency of the production cycle of each process should also be considered. Under normal circumstances, when a single piece is produced in small batches, only the process can be concentrated. In the processing of double eccentric flanges, although the processing accuracy is low and the batch size is small, according to the general principle, the process should be concentrated, but considering the structural characteristics of the parts, the existing production equipment and the technical level of the workers, the upper and lower parts of the double eccentric flange The centerl...
