Key word:

One, X62W all-purpose milling machine is electric control object pursues 1 it is X62W horizontal average milling machine is electric principle graph. This machine tool shares 3 electromotor: M1 is main shaft electromotor, in electric on need implementation starting control and apply the brake stop quickly turn control, arrange to finish mill and go against mill, still need to inverting control, in addition still need main shaft temporarily apply the brake in order to finish gearshift unit process of cargo bandling.

M2 is workbench feed electromotor, x62W all-purpose milling machine has horizontal workbench and circular workbench, among them horizontal workbench can realize fore-and-aft feed (have way of two or so feed) , transverse feed (have around two feed direction) and litre fall feed (have fluctuation) of two feed direction, 4 motion such as circular table roll, milling machine can undertake a feed moves only currently (2 cannot come true on average milling machine or above the linkage) that many feed move, through horizontal workbench transfer switch of operation handle, circular table, fore-and-aft feed operates handle, crossed double entry to operate the make choice of such as handle, the two feed direction that the positive and negative of the M2 after make choice of turns even if feed of place make choice of moves.

YA is fast tractive electro-magnet. After electrify of coil of fast tractive electro-magnet, tractive electro-magnet passes drawing the link control unit in fast clutch, make horizontal workbench and fast clutch join realize sudden shift, when YA cuts off the power, horizontal workbench come away is fast clutch, restore slow fast shift.

M3 is cooling pump motor, in main shaft electromotor only M1 starts hind, ability of cooling pump motor starts.

Graph 1X62W horizontal is common milling machine is electric principle graph

2, dynamical circuit knowledge is read 1. Main shaft turns circuit

Three-phase power source passes FU1 fuse, introduce the main circuit of X62W all-purpose milling machine by QS of power source switch-disconnector. In area of main shaft roll, FR1 is the heating element of hot relay, overload protects action since.

KM3 advocate touch a head to close, KM2 advocate when touching a head to disconnect, SA5 switchgroup has suitable mill, stop, go against mill 3 changeover position, control M1 respectively advocate of electromotor turning, stop, invert. Once KM3 advocate touch a head to disconnect, KM2 advocate touch a head to close, criterion KM2 of source current classics advocate touch R of resistor of current limliting of head, two-phase to be in of KS speed relay cooperate to issue implementation to receive apply the brake instead.

With advocate detecting element is opposite the KS speed relay that electromotor coaxial installs advocate electromotor undertakes speed monitoring, basis advocate the speed butt joint of electromotor is controlling the speed relay in circuit to touch head KS1, KS2 close with disconnect undertake controlling.
