Convex Lens Focusing and Positioning Method of Drilling and Milling Head of Drilling and Milling Machine

Abstract

The invention relates to a convex lens focusing and positioning method of a drilling and milling head of a drilling and milling machine, and belongs to the field of mechanical processing application. The method includes mounting a hollow convex lens to a shell of a motor through inner and outer sleeves to guarantee the focus of the convex lens being coaxial to the motor shaft, fine adjusting the position of the focus by adjusting a plurality of screws on the inner and outer sleeves to guarantee the focus of the convex lens being strictly coaxial to the motor shaft, arranging a parallel light source above the convex lens, and allowing the focus of the convex lens to locate right below the drilling head for 1 to 2cm. Since the focus is coaxial to the center of the drilling and milling head and the center of the spindle motor, if the center of the drilling and milling head is positioned to a point, only the focus is moved to the point as required; since the focus facula is visible, operation is facilitated. Compared with the prior art, the method has the advantages that positioning operation is simple, the position of the focus facula is the center of the drilling and milling head, the position of the center can be known by observing the facula by eyes, and positioning accuracy is high.

Description

[0001] 1. Technical field [0002] Drilling and milling machines are widely used in industrial production. From the production of manual parts, the processing of handicrafts, to the application of CNC machine tools, its applications are everywhere. However, in the process of processing, the positioning of the drilling and milling head is not a simple matter. The method of focusing and positioning with a convex lens in the present invention can well solve this problem. [0003] 2. Background technology [0004] The traditional positioning method is to draw a line before drilling to determine the center of the hole, and use a punch to punch a larger center hole in the center of the hole. When drilling, first drill a shallow pit to judge whether it is centered. In addition, some people use two lasers emitting straight lines to be fixed on both sides of the spindle motor base, and the intersection formed by the straight lines emitted by the two lasers is used as the center point o...

Problems solved by technology

[0007] In order to solve the above-mentioned problems of complicated positioning operation process, low positioning accuracy and poor stability, a hollow hemispherical convex lens can be fixed on the spindle motor housing, and a parallel light source is placed above the convex lens. The focus of the convex lens is located directly below the drilling and milling head for about At 1 to 2 cm, since the focal point is coaxial with the center of the drilling and milling head and the center of the spindle motor, to locate the center of the drilling and milling head to a certain point, you only need to move the focus to that point, because the light spot at the focal point is visible , it is very convenient to operate
