Vertical lathe is walked table transferring mechanism
(1) technical field
The utility model relates to a kind of vertical lathe, particularly relates to vertical lathe and walks table transferring mechanism.
(2) background technology
Existing vertical lathe is generally the Mobyneb numerical control and decides beam double-column vertical milling lathe, this kind lathe, except that having common turning function, the function that also has servo-actuated turning and servo-actuated milling bevel for welding, but because this kind equipment belongs to fixed, can not move up and down, move left and right is finished by artificial push-and-pull, uses extremely inconvenient.
(3) summary of the invention
The purpose of this utility model provides a kind of vertical lathe and walks table transferring mechanism, with solve existing vertical lathe walk on stage can not move up and down and about the problem that moves automatically.
The technical scheme that adopts is:
Vertical lathe is walked table transferring mechanism, comprises the walk on stage left/right movement device and the reciprocating mechanism of walking on stage, and the left/right movement device of walking on stage comprises motor, worm type of reduction gearing.Motor, worm type of reduction gearing are fixedly mounted on away the below of desktop machine base, be equiped with a drive sprocket on the output shaft of worm type of reduction gearing, walk on stage to be fixed with on two symmetrical supports, two supports on the pedestal and be equiped with a drive sprocket respectively, the left and right sides of walking on stage is fixed with the chain hold-down support respectively, sprocket wheel on the worm type of reduction gearing output shaft connects mutually by the drive sprocket of installing on a chain and two supports, and the two ends of chain are separately fixed on the chain hold-down support of the left and right sides of walking on stage, to realize walking on stage move left and right.
The reciprocating mechanism of walking on stage comprises column, slide mass, screw mandrel, screw, motor and worm reducer.Column is fixed on the ground, and slide mass is fixedlyed connected with walking on stage, and is nested with the outside at column.Motor, worm reducer are fixed on the top of column, and screw is fixed on the bottom of slide mass by nut seat, match with worm reducer in the upper end of screw mandrel, and the lower end of screw mandrel is screwed in the screw.
Upper and lower between above-mentioned slide mass and the column is equiped with the orienting roll wheels respectively.
The utility model is by improvements over the prior art, makes that walk on stage not only can free upper and lower lifting, and move left and right ends the dependence upon the manpower push-and-pull, and it is automatically controlled that the rising of walking on stage and descending is adopted fully, flexible movements, easy to operate, satisfy and produce needs fully.

(5) specific embodiment
Vertical lathe of the present utility model is walked table transferring mechanism, comprises the walk on stage left/right movement device and the reciprocating mechanism of walking on stage.
See also Fig. 1 and Fig. 2, the left/right movement device of walking on stage comprises motor 1, worm type of reduction gearing 2, and motor 1 and worm type of reduction gearing 2 are fixed on the pedestal 3 of walking on stage, walking on stage is fixed with track 4 on the pedestal 3, walks on stage 5 can go up roller 6 move left and right on track 4 of installing by it.One drive sprocket 7 is installed on the output shaft of worm type of reduction gearing 2, walk on stage and be fixed with two supports 8 on the pedestal 3, be equiped with a drive sprocket 9 on two supports 8 respectively, walk on stage 5 the left and right sides is fixed with a chain hold-down support 10 respectively, drive sprocket 7 on worm type of reduction gearing 2 output shafts connects with two drive sprockets 9 respectively mutually by a chain 11, and the two ends of chain 11 are fixedly connected on respectively on two chain hold-down supports 10.Walk on stage and 5 can drive move left and right by chain 11.
See also Fig. 3 and Fig. 4, the reciprocating mechanism of walking on stage comprises column 12, slide mass 13, screw mandrel 14, screw 15, motor 16 and worm reducer 17.Column 12 is the square tube shape, its lower end is fixed on the ground, slide mass 13 also is the square tube shape, slide mass 13 is nested with the outside at column 12, motor 16 and worm reducer 17 are installed in the upper end of column 12, screw 15 is fixed on the bottom of slide mass 13 by nut seat 18, and the upper end of screw mandrel 14 is meshed with the output shaft of spiral shell wheel decelerator 17, and its lower end is screwed in the screw 15.
Together with the 5 column 12 generation impacts in the process of moving up and down of walking on stage, on 19, two fixed pulleys 19 of column 12 tops two fixed pulleys of installation steel wire rope is arranged around the home for fear of slide mass 13, steel wire rope is fixed on the balance weight body 20.
For the ease of maintenance, vertically be provided with staircase 21 in the outside of slide mass 13, staircase 21 is fixed on the column 12.
For slide mass 13 is moved on column 12 easily, upper and lower between slide mass 13 and column 12 is separately installed with orienting roll wheels 25, these orienting roll wheels 25 comprise 8 rollers 22, wherein two rollers 22 are positioned near column 12 1 sides, and be installed on respectively on two roller shafts 23 that are fixed on the rolling element, other 6 rollers 22 are distributed on rolling element 13 other three sides, and are installed in the roller mount 24 fixing on the slide mass 13.
