Turning machining mechanism for parts with formed curves

Abstract

The invention discloses a turning machining mechanism for parts with formed curves. The turning machining mechanism comprises a cutter head, a clamp, a press plate and a screw, wherein the cutter headis installed on a main shaft of a numerically-controlled lathe, and the main shaft of the numerically-controlled lathe drives the cutter head to rotate; a main body of the clamp is installed on a middle supporting plate of the numerically-controlled lathe, and the middle supporting plate of the numerically-controlled lathe drives the clamp to move in the X-axis direction and the Z-axis direction;and the clamp is located just under the cutter head, a dowel used for locating a part to be machined is arranged on the clamp, and the part to be machined is fixed to the clamp through the press plate and the screw. The cutter head of the turning machining mechanism disclosed by the invention is simple to customize, only needs to be grinded into a sharp corner, and is low in expense; the cutter head is easy in edge sharpening, and is low in cutting force, stable in cutting and free from damage to a machine tool due to line contact of the cutter head with the part; and even if the shapes of the formed curves need to be changed, only machining procedures need to be adjusted, the cutter head does not need to be subjected to cutter grinding again, and the adjustment is convenient, so that time and expense are greatly saved, the machining efficiency is increased by 20%, and the cost is lowered by 50%.

Description

technical field [0001] The invention belongs to the technical field of parts processing, and in particular relates to a turning processing mechanism for forming curved parts. Background technique [0002] Now, if figure 1 The shown belt forming curve type parts are widely used in industrial sewing machines, and the amount is large. These belt-shaped curved parts used to be milled horizontally. figure 2 The shown special cutter head is realized, and its realization process is as follows: [0003] The part (C) is fitted with its own hole and the pin on the fixture (B), mounted on the fixture (B), and the part (C) is pressed by the pressing plate (D) and the screw, and the main body of the fixture (B) is installed on the milling machine On the worktable, the spindle of the milling machine drives the tool (A) to rotate. The upper teeth of the tool (A) have the same curve as the part (C), and the milling machine drives the part (C) to move relative to the tool (A). C) The cu...

AI Technical Summary

Problems solved by technology

[0005] 1. Because of the high production cost of the tool (customized tool), the processing cost is high;

[0006] 2. The blade of the tool is not easy to sharpen, and the processing contact surface is large, resulting in a very large processing force, which is especially easy to damage the gear of the milling machine;

[0007] 3. If the forming curve is changed or the shape is out of tolerance, the tool needs to be re-sharpened, which will prolong the processing cycle and increase the cost
