Description

Lowering or hoisting gear

Technical field

The utility model relates to the deep hole machining machine, is meant the lowering or hoisting gear on the deep hole working machine especially.

Background technology

General deep hole machining machine is to be used at the processing of holing of the thicker material of thickness, or drilling depth is used when surpassing the limit of common drilling machine, during at present common on the market deep hole machining machined, be that article to be processed are placed on a workbench, and but workbench one side is the fast headstock that is equiped with a vertical lift, and be provided with a drill spindle that can move horizontally on the fast headstock again, because being group, fast headstock is located at a holder front, rely on a suitable lowering or hoisting gear, can make fast headstock on holder, make the lifting moving of vertical direction; See also Fig. 1, structural representation for existing lowering or hoisting gear, as shown in FIG., its lowering or hoisting gear 10 is to have comprised a track 101, one chute 102, one motor 103 and a weight device 104, wherein, track 101 is on three fins 201 of parallel group of positive institute moulding that is located at holder 20, chute 102 then is molded on the position of fast headstock 30 with respect to track 101, it is positioned at the track 101 of holder 20 both sides, be outwards to form a hook portion 1011 respectively, and 30 groups of fast headstocks must be located on the holder 20, utilize hook portion 1011 to collude and be located in the chute 102, and be to be equiped with the auxiliary roller 1021 that slides on its contact-making surface, again, all leave certain interval at

chute

102 and 101 of two siding tracks, so that fast headstock is located at holder 20 for 30 groups, and the slide rail 101 of holder 20 central authorities only leans on holder 20 surfaces, its excessive gap can have influence on fast headstock 30 rocking when moving, vertical levelness when mobile with fast headstock 30, therefore, 101 on the chute 102 of a side and track are equiped with one and adjust piece 1022 therein, be used for pushing track 101 to reduce its gap, error when reducing lifting takes place, but the DeGrain of this adjustment mode, levelness when Chang Wufa keeps fast headstock 30 and moves, and can cause the frictional force when mobile to increase, so be necessary to be improved.

Because above-mentioned demand, the utility model the designer hence study intensively, and long-pending individual is engaged in the many years of experience of described cause, designs a kind of brand-new lowering or hoisting gear eventually.
