Abstract
The utility model relates to a beam lifting box structure. The beam lifting box structure is mainly characterized in that a first gear is arranged on a transmission shaft which is arranged on a box body through a first bearing assembly, a second gear is arranged on a worm which is arranged on the box body through a second bearing assembly, and the first gear and the second gear are externally meshed to achieve transmission. Two deep groove ball bearings are arranged in worm gear holes, a worm gear is arranged on a lifting screw rod which penetrates through a shaft sleeve hole and is tightened by two locking nuts. A locking device is arranged on the upper end of the lifting screw rod, the worm gear and the worm are meshed for transmission, and beam lifting is achieved. An original top cover structure is replaced by the beam lifting box structure, two lifting box structures are respectively arranged on the tops of stand columns, size of the lifting structure is reduced, meanwhile, materials are saved, and economic performance for use is improved.
Description
Technical field
The utility model relates to a kind of beam lifting box structure, is specially adapted to the vertical lathe crossbeam elevating mechanism, belongs to the machinery industry field.
Background technology
Vertical lathe crossbeam fast lifting structure can reach desired location fast, increases work efficiency.At present, the elevator chamber structure of vertical lathe crossbeam adopts the top cover lifting structure of casting mostly, at top cover worm gear, worm screw is installed, and drives the beam lifting screw mandrel and rotates, realize the rise and fall of crossbeam, but in this structure, owing to adopting the casting coping structure, the top cover volume ratio is larger, weight ratio is heavier, both increased the weight of the lathe own wt after the installation, and wasted again material, its usage economy can be low.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of beam lifting box structure simple in structure, ingenious, rational is provided, this structure Effective Raise its usage economy energy.
The technical scheme that provides according to the utility model: a kind of beam lifting box structure, feature is: comprise casing, power transmission shaft, the first gear, clutch shaft bearing assembly, worm screw, the second bearing assembly, the second gear, worm gear, elevating screw; Described the first gear connects by the first flat key, be installed on the power transmission shaft, power transmission shaft is installed on the casing by the clutch shaft bearing assembly, the second gear connects by the second flat key, is installed on the worm screw, and worm screw is installed on the casing by the second bearing assembly, the first gear and the second gear external toothing, realize transmission, axle sleeve is fixed by screws in the box body hole, plane bearing, is installed on the axle sleeve; Two deep groove ball bearings are installed in the worm wheel aperture, described worm gear connects by the 3rd flat key, is installed on the elevating screw, and the hole that elevating screw passes axle sleeve with two locking nuts and tightly, described worm gear, worm screw are meshed and consist of worm gear, worm-drive, realize beam lifting.
As further improvement of the utility model, separate with pad in the middle of described two deep groove ball bearings.
As further improvement of the utility model, locking device is installed in described elevating screw upper end, is used for preventing the elevating screw axial jump.
The utility model compared with prior art, advantage is: the elevator chamber structure replaces original cap structure; Adopt two elevator chamber structures to be installed in respectively the column top, reduced the lifting structure volume, also saved material simultaneously, improved its usage economy energy.
