AI Technical Summary

Problems solved by technology

[0002] Thin-walled parts have complex structures and poor rigidity
When using CNC lathe, it is easy to deform the product assembly and affect the accuracy
For example, the outer circle tolerance of a thin-walled part is 0.06mm, the coaxiality requirement is 0.1mm, the wall thickness of the thinnest part of the workpiece is 2.25mm, and there are many inclined grooves on the outer circle surface. The traditional processing method, the three-jaw clamping correction of the CNC lathe, When finishing the outer circle and inner hole, the product is easily deformed by force, and the size will be out of tolerance to varying degrees
After sharing the outer circle and inner hole, it is necessary to use the machining center to process the chute and side hole. At this time, the product shape has been finished in place, and the outer circle surface cannot be overstressed, and soft jaws cannot be used for correction. Any clamping Tight force may deform thin-walled parts
The traditional processing method requires high technical experience of the processor, and the processing yield is low

Embodiment Construction

[0019] This embodiment discloses a method for processing thin-walled parts. The material to be processed is Incoloy 825. Incoloy 825 is a titanium-stabilized full austenitic nickel-iron-chromium alloy with copper and molybdenum added. The parameters of the finished thin-walled parts are: the wall thickness of the thinnest part is 2.25mm, the outer circle size is φ129.8±0.03mm, the coaxiality of the outer circle is required to be 0.1mm, the roughness requirement is 1.6, and the product length is 598.5mm. The processing method is to design three sets of tooling on the basis of the existing CNC lathe processing method, namely a set of tooling for expanding the inner hole and finishing the outer circle, a set of tooling for clamping the outer circle and finishing the inner hole, and a set of The tooling for processing grooves, the processing steps are:

[0020] 1) Use CNC lathe for semi-finishing, leaving allowances for the outer circle and inner hole of the workpiece;

[0021] 2...

Abstract

The invention discloses a thin-wall part machining method, which is characterized in that three fixtures are designed by using an existing numerical control lathe for machining and respectively include an expansion sleeve inner hole fixture for fittingly finishing an outer circle, a clad outer circle fixture for fittingly finishing an inner hole and a fixture for a machined groove. The thin-wall part machining method includes the machining steps: using the numerical control lathe for semi-finishing, setting the expansion sleeve inner hole fixture for finishing the outer circle, setting the clad outer circle fixture for finishing the inner hole and setting the fixture for the machined groove. By the aid of the method, a thin-wall part can be precisely machined, the requirements on experience and techniques of machining workers are lowered, and machining precision and yield are greatly improved.

Description

technical field [0001] The invention relates to a processing method of a metal part, in particular to a processing method of a thin-walled part which can effectively control the processing accuracy. Background technique [0002] Thin-walled parts have complex structures and poor rigidity. When using CNC lathes, it is easy to deform the product assembly and affect the accuracy. For example, the outer circle tolerance of a thin-walled part is 0.06mm, the coaxiality requirement is 0.1mm, the wall thickness of the thinnest part of the workpiece is 2.25mm, and there are many inclined grooves on the outer circle surface. The traditional processing method, the three-jaw clamping correction of the CNC lathe, When finishing the outer circle and inner hole, the product is easily deformed by force, and the size will be out of tolerance to varying degrees. After sharing the outer circle and inner hole, it is necessary to use the machining center to process the chute and side hole. At ...
