Non-circular ring-like thin-walled part machining process and thin-walled part clamping tool thereof

Abstract

The invention relates to a non-circular ring-like thin-walled part machining process and a thin-walled part clamping tool thereof. A non-circular ring-like thin-walled part is clamped through the thin-walled part clamping tool for side wall machining, rough machining, semi-finish machining and finish machining are conducted through an inner ring and an outer ring correspondingly, vibration cannotbe generated in the machining process, and the surface quality of a to-be-machined part is improved. The working efficiency is improved.

Description

technical field [0001] The invention relates to a non-circular annular thin-walled part processing technology and a thin-walled part clamping tool, belonging to the field of numerical control processing. Background technique [0002] Thicken the thickness of the part blank by 30mm, make a craft table, first process the upper and lower parts of the part to 120mm±0.2, find the center of the circle, and drill 8-Φ10.5 holes evenly distributed on the upper surface of the part. The depth is 25mm, and tap the M12 thread. Install the parts on the tooling board, fix them with countersunk head M12 screws, align the parts on the CNC machining center, establish a coordinate system, press the tooling board on the worktable of the CNC machining center, use T50R6 to open the rough inner shape, and cut the body with each knife 0.5, the margin is 0.3mm, T50R6 is used for semi-finishing inner shape, each cut is 0.45, the allowance is 0.05mm, and T50R6 is used for finishing the inner shape, an...

Problems solved by technology

[0003] This kind of processing technology is direct finishing, and the raw material of the part is increased by 30mm. The production process table, titanium alloy material is relatively expensive, which increases the cost, prevents the outer wall of the part from shaking during the processing process, and leaves a 3mm margin for roughing, which can minimize the shaking of the outer wall of the part. However, the finishing allowance is large, the blade wears a lot, and the blade needs to be replaced in the middle, and there will be deep knife connection marks, leaving 0.4mm in the finishing allowance, which brings great work intensity to the fitter. As we all know, titanium alloy is For difficult-to-machine materials, it takes a long time for the fitter to polish, and the parts cannot be overheated, and the wall thickness is too thick to ensure the dimensional accuracy. It needs repeated grinding and inspection to meet the drawing requirements, which is costly and inefficient.
