Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described, but must not by any way this utility model be added
To limit, any change made based on this utility model training centre or improvement, belong to protection domain of the present utility model.
As shown in Figure 1 and 2, this utility model includes casing 1, the case lid 2 that is arranged on casing 1, is arranged on case lid 2
Servomotor 3 and the milling unit being arranged in casing 1, the power transmission shaft of described servomotor 3 is arranged through case lid 2 and its end
Travelling gear 5, described milling unit includes that milling head axle 13, driven gear 7, chuck 18, described milling head axle 13 top are arranged passively
Gear 7 engages cooperation, the extension of the described down-set smooth in appearance of driven gear 7 with travelling gear 5, sets outside this extension
Put door 9, spring bearing 11, described spring bearing 11 and driven gear 7 are set between described casing 1 internal upper part and milling head axle 13
Extension lower end between spacer ring II 10 is set, arrange between described casing 1 bottom and milling head axle 13 location bearing 14, described
Between support bearing 11 and location bearing 14, spacer ring III 12 is set, described chuck 18 by nut 17 be connected to milling head axle 13 lower end and
Prominent casing 1, arranges gland II 16, between described gland II 16 and milling head axle 13 between described casing 1 lower end and milling head axle 13
Arranging sealing ring 15, described milling head axle 13 upper end arranges gland I 6.
A corresponding milling unit in multiple vertical through hole and each through hole are set in described casing 1.
