Detailed description of the invention
The utility model device simple to operate, safe and reliable, automaticity is higher, after artificial loading to the feeding station of automatic preheater, preheating device carries out automatic preheating to gear, after preheating completes, the manipulator of automatic notice laser gear welding machine captures preheated gear and welds, and realizes the automated production of gear welding.Detailed description of the invention is as follows: after complete machine opening initialization, and three stations are all without duplicate gear to be welded (11), and indexing rotary table (23) stops the rotation, and treats material loading.The duplicate gear press-fited (11) is positioned in the heating charging tray (12) on feeding station (9) by operator, after Fibre Optical Sensor (8) detects duplicate gear (11), alternating current generator (22) rotates a station by Cam splitter (21) driving indexing rotary table (23) clockwise to be stopped afterwards to heating station (5).Now feeding station (9) is in room, and operator puts a duplicate gear (11) again as standby weldering.
Then, servomotor (2) clockwise rotates, screw mandrel (15) is driven to rotate forward by driving wheel (1), follower (17), Timing Belt (18), screw mandrel moves down with slide unit (3), induction heater (14), eddy-current heating head (19), and is extend into completely by eddy-current heating head (19) in the circular hole in the middle of duplicate gear (11).
Then cylinder (24) stretches out, and promotion translator slider (27), sliding panel (26) move right, until glue coating wheel (28) contacts with friction pulley (20); Buncher (29) starts to rotate, and glue coating wheel (28) drives friction pulley (20), heating charging tray (12), duplicate gear (11) to rotate; After duplicate gear (11) starts rotation, eddy-current heating head (19) starts electrified regulation, and while namely duplicate gear (11) rotates, eddy-current heating head (19) is to its heating.When infrared temperature probe (13) detects that duplicate gear has reached design temperature, namely stop heating, if temperature does not reach setting value, then continue heating, until temperature reaches setting value, the stable closed loop control of temperature can be realized like this.
Then, servomotor (2) rotates counterclockwise, and screw mandrel (15) reverses, and eddy-current heating head (19) is mentioned; Then cylinder (24) is retracted, and glue coating wheel (28) and friction pulley (20) depart from, and heating charging tray (12) is stopped the rotation; Alternating current generator (22) drives indexing rotary table (23) clockwise to rotate a station and stopping by Cam splitter (21).The complete duplicate gear (11) of now preheating has arrived discharge station (10), to be taken away by the duplicate gear in discharge station (10) weld with the manipulator of the laser gear welding machine of this matched with devices; While feeding, new duplicate gear to be welded can be positioned in feeding station (9) by operator, then starts new one and takes turns circulation.
