Positioning device of CNC engraving and milling machine

Abstract

The invention discloses a positioning device of a CNC engraving and milling machine. The positioning device comprises a device body, wherein a base is arranged on the bottom end of the device body, abearing frame is arranged on the top end of the device body, a frame is arranged on the bearing frame, a lifting gear is installed in the frame, a plurality of lifting teeth are arranged on the innerwall of the frame, an engraving mechanism is arranged on the bottom end of the frame, a worm is arranged on one end of the lifting gear, a connecting rod is installed on one end of the worm, a drivinggear is arranged on the bottom end of the connecting rod, a motor is arranged on one end of the driving gear, and a CNC engraving and milling mechanism, a fixed rod and a lifting rod are installed between the frame and the connecting rod. The positioning device has the advantages of novel structure and simplicity and convenience in operation, air pressure in an air tap is changed by virtue of anair cylinder which is externally connected with an air pipe, so that glass is adsorbed, and an infrared signal of an infrared induction lamp is received by an infrared receiver, so that engraving, grinding and CNC engraving and milling are performed in the glass, the operating errors are reduced, the glass engraving quality is increased, defective products are reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to a fine carving machine, in particular to a positioning device for a fine carving machine. Background technique [0002] At present, glass engraving machine is a kind of CNC machine tool, also known as: glass engraving machine, glass punching machine, glass edging machine, special-shaped glass cutting machine, glass slotting machine, precision glass forming machine, glass engraving machine is A kind of CNC machine tool, mainly used in the fine processing and special-shaped cutting of various ultra-thin glass. It is easy to be damaged, so the fine molding process of glass is difficult, it is not convenient for multi-section carving, and it is not easy to position, resulting in more defective products and increasing production costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the difficulty of the existing fine glass forming process, which is inconvenient for mu...
