Inner and outer circle finish turning positioning device and method of circular saw web

Abstract

The invention provides an inner and outer circle finish turning positioning device and method of a circular saw web, which belongs to the technical field of mechanical machining equipment, and is used for positioning the circular saw web in a machining process. The technical scheme of the invention is as follows: the inner and outer circle finish turning positioning device of the circular saw web is composed of a centering sleeve and a centering shaft, wherein the inner diameter of the centering sleeve is matched with the outer diameter of the centering shaft; the center of a vertical lathe accepting disc is provided with a through hole, and the centering sleeve is embedded into the through hole; and the upper and lower end faces of the centering shaft are provided with screw holes. The machining method comprises the following steps of: inserting the centering shaft into the centering sleeve to be fastened; aligning the centering shaft and a rotary center of a working table to the same central line; arranging central holes of a plurality of circular saw webs on the centering shaft, wherein the gap between two circular saw webs is 0.2-0.4 mm; pressing the circular saw webs through a technical hole or a pressing device, and pulling out the centering shaft; and machining an inner hole and an outer circle of each circular saw web. The device and method provided by the invention can rapidly and accurately center and align the circular saw webs when the circular saw webs are machined, so as to guarantee the machining precision of the circular saw webs and realize a very good effect.

Description

technical field [0001] The invention relates to a precision turning positioning device and method for processing the inner and outer circles of a circular saw blade, and belongs to the technical field of machining equipment. Background technique [0002] Circular saw blades are highly efficient tools widely used in metallurgy, machinery, stone processing and other industries. The finishing of the inner hole and outer circle is an important process that affects the accuracy of circular saw blades. According to the different types of circular saw blades, there are various rough machining methods for the inner hole and outer circle of circular saw blades, such as laser cutting, plasma cutting, flame cutting, shearing, turning, etc., but finishing is based on fine turning. Mainly, for the finishing turning equipment commonly used for medium and large circular saw blades, vertical lathes are generally used. Install the adapter plate on the workbench, place the circular saw blade ...

According to the different types of circular saw blades, there are various rough machining methods for the inner hole and outer circle of circular saw blades, such as laser cutting, plasma cutting, flame cutting, shearing, turning, etc., but finishing is based on fine turning. Mainly, for the finishing turning equipment commonly used for medium and large circular saw blades, vertical lathes are generally used. Install the adapter plate on the workbench, place the circular saw blade on the adapter plate, and turn the inner and outer circles after fastening. The current problem is: when the circle When the saw blade does not have a craft hole, the circular saw blade cannot be fastened on the connecting plate conveniently. When the circular saw blade is aligned, a positioning mandrel is needed as an auxiliary tool, but it is troublesome to operate
