[0003] However, for the fillet-like chamfering of the edge of the plate-shaped workpiece, for example, the "Kawasaki R Cutter Robot" developed by Kawasaki Heavy Industries Group has been proposed (the "2010 International Welding Robot" held at Tokyo BIGSIGHHT in late April 2012) "exhibition" such as fully automatic equipment with extremely high equipment costs and processing costs. Generally speaking, at present, it is still necessary to rely on grinding-type sharpening or cutting-type cutting knives (such as The above-mentioned chamfering process is performed by referring to the manual work of Patent Document 1)

Embodiment Construction

[0025] Hereinafter, preferred embodiments of the fillet chamfering machine for plate-shaped workpieces according to the present invention will be described based on the drawings.

[0026] First, refer to figure 1 and figure 2 A circular opening 3 is formed in the center of the table 2 provided on the machine frame 1, and a plurality of free ball bearings 4 are installed at appropriate intervals in a state protruding slightly from the surface over the entire area. This enables the workpiece to move freely in all directions.

[0027] The spindle device 5 is located substantially below the central portion of the table 2 as a whole, and includes a spindle head 6 as a main part. The spindle head 6 includes: The shaft device 8 is connected to the motor 9 of the main shaft 7 .

[0028] At the upper end of the main shaft 7, a chamfering cutter 10 is integrally rotatably fixed, and at the uppermost end adjacent thereto, a stop screw shaft 12 concentrically fixed to the main shaft 7...

Abstract

The invention provides a round cornering and chamfering machine of a plate-shaped workpiece, which has a compact structure and small setting space and can conduct chamfering with high efficiency. A platen (2) having a free ball bearing (4) is provided with an opening part (3) at a central part. A main shaft device (5) having a spindle head (6) is disposed at the lower part of the central part. The front end part of a main shaft (7) protruding from the opening part of the platen is provided with a workpiece guide roller (11), a chamfering cutter (10) and a workpiece bearing bench (14) having a bench base (15). A main shaft periphery part from the lower part of the platen to the upper part of the platen is provided with a workpiece conveying device (40). The workpiece conveying device (40) comprises a conveying unit (41) which is disposed at the upper part of the platen and opposite to the working bearing bench, and a pedaled conveying roller elevating mechanism (47) in a manner that the conveying unit approaches to or moves away from the workpiece bearing bench of the spindle head.

Description

technical field [0001] The present invention relates to a chamfering machine for chamfering the edge of the outer peripheral portion of a plate-shaped workpiece or the edge of the inner peripheral portion of an opening (hole) formed in an inner region of the workpiece into a rounded shape. Background technique [0002] It is well known that for plate-shaped workpieces such as steel plates, which are formed by gas fusion or pressure punching, etc., for ship structures, etc., the edges need to be chamfered into a rounded shape especially in order to improve the quality of painting. [0003] However, for the fillet-like chamfering of the edge of the plate-shaped workpiece, for example, the "Kawasaki R Cutter Robot" developed by Kawasaki Heavy Industries Group has been proposed (the "2010 International Welding Robot" held at Tokyo BIGSIGHHT in late April 2012) "exhibition" such as fully automatic equipment with extremely high equipment costs and processing costs. Generally speak...
