Abstract
The invention relates to a cross beam lifting box structure. Primarily, a first gear is arranged on a transmission shaft; the transmission shaft is arranged on a box body through a first bearing assembly; a second gear is arranged on a worm; the worm is arranged on the box body through a second bearing assembly; the first gear is externally engaged with the second gear to realize transmission; two deep groove ball bearings are arranged in a worm wheel hole; the worm wheel is arranged on a lifting lead screw; the lifting lead screw penetrates through a hole of a shaft sleeve to be tightened by using two locking nuts; an anti-loose device is arranged at the upper end of the lifting lead screw; and the worm wheel is engaged with the worm to form worm wheel and worm transmission so as to realize lifting of a cross beam. According to the cross beam lifting box structure, the original top cover structure is substituted by the lifting box structure; and two lifting box structures are arranged on the top of a stand column respectively, so that the size of the lifting structure is reduced, meanwhile, the material is also saved, and the operational performance and the economic performance are improved.
Description
Technical field
The present invention relates to a kind of beam lifting box structure, be specially adapted to the vertical lathe crossbeam elevating mechanism, belong 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 adopt 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 object of the invention is to overcome the deficiencies in the prior art, a kind of beam lifting box structure simple in structure, ingenious, rational be provided, this structure Effective Raise its usage economy energy.
According to technical scheme provided by the invention: 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 a further improvement on the present invention, separate with pad in the middle of described two deep groove ball bearings.
As a further improvement on the present invention, locking device is installed in described elevating screw upper end, is used for preventing the elevating screw axial jump.
The present invention 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.
