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
The present invention relates to field of machining, be specifically related to double eccentric flange processing method.
Background technology
When drafting process route, the degree that operation is centralised or decentralised, depend primarily on the structure spy of production scale, part
Point and technology requirement, it is also contemplated that the concordance of each operation productive temp sometimes.Generally, during Single unit job lot production,
Can only operation concentrate.And in double eccentric flanges are processed, although requirement on machining accuracy is low, the least, according to rule, and suitable work
Sequence is concentrated, but in view of design of part feature, existing equipment and workman's technical merit, this pair of upper and lower surface of eccentric flange
Centrage is respectively arranged with the eccentric throw of a 3mm relative to work centre line, and the most to the right, left shift, cause flange inside and outside circle
Eccentric with two installation basic circles of screw thread.Its material is Q235, maximum diamater of work 184mm, and thickness 27mm belongs to typical dish
Cover parts.This part quality is about 15kg, belongs to small lot batch manufacture.This element precision is relatively low, just can meet through roughing
The requirement of dimensional accuracy, surface roughness and the accuracy of form and position, but existing processing method is relatively costly.
Summary of the invention
In order to solve the problems referred to above, the present invention provides a kind of simple to operate, convenient processing, and can guarantee that workpiece add working medium
Amount and machining accuracy, improve production efficiency, reduces double eccentric flange processing methods of production cost.
The double eccentric flange processing method of the present invention, comprises the following steps:
The first step, Numerical control cutting, by the steel plate stock layout of thickness 30mm on numerical control cutting machine, cutting stock outside diameter 190mm,
Diameter of bore 80mm；
Second step, car, C616 lathe presss from both sides upper surface, car lower surface, turning to diameter 184mm, endoporus car is to diameter
84mm, presss from both sides lower surface, car upper surface, it is ensured that thickness 27mm；
3rd step, line, on vice bench, it is clipped in the centrage of flange symmetry on cylindrical on dividing head with vernier height gauge
Mark；
4th step, number car, on CK630 numerically controlled lathe, clamp a scroll chuck with the anti-pawl of chuck, first will with dial gauge
Mark line is carried out after eccentric 3mm adjustment is qualified, one flange of clamping on scroll chuck, first car lower end after centring line of ruling
Face, then car diameter 100mm endoporus and groove；
5th step, presss from both sides lower surface, after the position of the mark line on alignment chuck is overturn 180 ° of alignment line, car boss one side
End face, it is ensured that thickness 27mm, reprocessing diameter 124mm cylindrical, diameter 108mm endoporus and diameter 100mm endoporus, manual grinding
Burr, the burr of cylindrical chamfering on another lathe is removed；
6th step, milling, in BV100 vertical machining centre, clamp diameter 184mm excircle orientation with scroll chuck, by bias be
Bottom diameter 10mm on two reference diameter 154mm of 6mm comes outbreak out, a wherein orifice chamfer, during installation, in drawing
Line on heart line chuck to be directed at, adjusts bottom outlet coordinate position；
7th step, tapping after an other orifice chamfer, burr of polishing；
8th step, checks each size, and oiling warehouse-in.
The present invention is simple to operate, convenient processing, and can guarantee that crudy and the machining accuracy of workpiece, improves and produces effect
