Processing method of molding curve part and device used in same

Abstract

The invention relates to a processing method of a molding curve part and a device used in the same. The method comprises the following steps of: customizing a rough milling cutter according to the curve shape of a curve part to be processed; roughly milling the curve part to be processed by using the customized rough milling cutter, and forming a rough molding curve on the surface of the part to be processed; quenching the roughly milled part; polishing a grinding wheel by using the device provided by the invention, forming a shape consistent with the molding curve of the part on the surface of the grinding wheel; and accurately grinding the quenched part by using the ground grinding wheel to obtain a part with an accurate molding curve. The device provided by the invention comprises a grinding machine with a machine body, a grinding wheel corrector, a main shaft and a grinding wheel, wherein the main shaft is arranged on the machine body and is capable of rotating around the axis per se, the grinding wheel is coaxially arranged on the main shaft and rotates under the drive of the main shaft, a horizontal support plate and an explorator which are capable of moving along the X axis direction and the Y axis direction are arranged on the machine body, and the grinding wheel corrector is used for grinding the grinding wheel according to the outline of the upper surface of the explorator under the action of the horizontal support plate and a pressure spring.

Description

technical field [0001] The invention relates to a processing method of a part and a device used therefor, in particular to a processing method of a part with a forming curve in a sewing machine and a fine grinding device used for processing the part. Background technique [0002] In the sewing machine, the curve profile is mainly used to control and adjust the needle pitch, so the profile of the curve determines the smoothness of the machine operation and the uniformity of the needle pitch, and the roughness of the curve also determines the wear of the matching parts. Therefore, higher requirements are placed on the profile and smoothness of the part curve during processing. The existing machining process for forming curved parts is generally divided into the following steps: (1) Customize the rough milling cutter and fine milling cutter according to the shape of the curve; (2) Process the part with the rough milling cutter customized in step (1) , forming a rough forming c...

Problems solved by technology

It can be seen from the above steps that the forming curve in the prior art is mainly realized by a milling machine with the help of a forming tool. Therefore, the profile of the curve depends on the profile of the tool during processing. If you want to change the profile, you need to modify it. Grinding tools is obviously difficult to achieve; in addition, during processing, the speed of the milling machine is low. After quenching, the surface hardness of the parts is high, and it is difficult for the milling machine to make the parts meet the ideal finish requirements, so it is achieved by polishing. , which increases labor intensity and difficulty, while polishing may lead to changes in profile, resulting in unqualified products
