Numerical control plasma six-shaft five-linkage groove cutting machine

Abstract

The invention discloses a numerical control plasma six-shaft five-linkage groove cutting machine. A rotating motor is installed on the top of a case of a host machine and connected with a ball screw rod in the case; the upper end of the ball screw rod is provided with a small gear, and the middle is in thread connection with a sliding block; one end of the sliding block is matched with a concave-convex groove of a vertical guide rail on the side wall of the case, and the other end is connected with a reset approaching switch; the reset approaching switch corresponds to a limiting block on theside wall of the case; the case is also provided with a hollow rotating shaft, and a big gear is connected to the rotating shaft; the big gear is meshed with the small gear; the lower end of the rotating shaft is fixed to the upper end of a C-shaped connecting piece; a reduction box driven by a swinging motor is installed on the C-shaped connecting piece and meshed with a semicircular rack by thegears; a cutting torch seat is installed on the rack; a cutting torch clamp is arranged on the contact surface of the cutting torch seat; a magnet is inlaid on the contact surface of the cutting torch seat; and a touch resistant approaching switch is vertically installed in a through hole of the clamp. The invention has the characteristics of accurate rotary resetting, verticality online compensation and high cutting precision.

Description

1. Technical field [0001] The invention relates to a numerically controlled plasma bevel cutting machine, in particular to a numerically controlled plasma six-axis five-linkage bevel cutting machine. 2. Background technology [0002] CNC plasma bevel cutting machine is a multi-axis linkage compound motion cutting machine, which can form V, X, Y-shaped bevels at one time, and complete the bevel processing completed by traditional cutting, milling and other multiple processes at one time, greatly Improve efficiency and save resources. The CNC plasma bevel cutting machine currently in use has been developed to a six-axis five-linkage form with a higher degree of automation. The most fatal defect of plasma cutting is that the arc is not vertical, which causes the cut surface of the cutting workpiece to be inclined. The non-perpendicularity of plasma imported from the United States in the early days was as high as 7 degrees, and the non-perpendicularity of the latest HPR series...

Problems solved by technology

This structure is improved compared with the traditional cutting torch anti-collision device, but it is still difficult to adjust the cutting torch to ensure that it works at a certain angle with a spring connection, which also affects cutting accuracy
