Abstract
A hydraulic locking device for a vertical lathe comprises a beam and a vertical column. A hydraulic device, a slope slider and a compression device are arranged on the beam, the hydraulic device comprises a hydraulic cylinder, a piston and a piston rod, the outer end of the piston rod is fixedly connected with the slope slider, the compression device comprises a clamping lever, a compression support, an insetting board, a stud bolt and a clamping pin, a locking wheel matched with the slope slider is arranged at one end of the clamping lever, and the other end of the clamping lever is abutted to the clamping pin above the clamping lever. Locking force of the beam and the column is adjustable, no clamping force for the beam and the column exists when the locking mechanism is loosened, friction between the beam and a guide face of the column is reduced to the minimum, the beam is capable of sliding in friction vertically and freely under action of a balance cylinder, wear of the guide face of the column of the lathe is low, power consumption is low, and machining precision retention is fine.
Description
(1) technical field
The utility model relates to hydraulic locking apparatus, especially the crossbeam of vertical lathe and the hydraulic locking between column.
(2) background technology
At present, the crossbeam of vertical lathe commonly used generally adopts dovetail groove with being connected of column, versions such as T type groove, the twin shaft that moving through between crossbeam and the column is fixed on the crossbeam is stretched the ac motor driving, by worm gear pair and double lead crossbeam is moved up and down, owing to there is not self-locking device, so generally all adopt the locking of mechanical type butterfly spring, hydraulic pressure unloads the version of power, this structure makes crossbeam be in the mechanical interlocking state when not moving, pass through the hydraulic pressure ejecting mechanism during motion, the disk spring deflection is reduced, reach lubricated the moving between crossbeam and column.More than the locking mode of this structure, its shortcoming is: the size of coupling mechanism force is difficult to control and holds, and needs when mobile, the hydraulic thrust size also is difficult to know.The result who causes is that frictional resistance is excessive or too small between crossbeam and column, big, the power consumption height that weares and teares mutually when excessive, and guide pass is not durable; Lathe rigidity shortcoming when too small easily causes vibration, defect such as machining accuracy reduction.
(3) summary of the invention
The purpose of this utility model provides a kind of device of new type hydraulic retaining mechanism, the crossbeam of vertical lathe and the coupling mechanism force size between the column can be regulated, thereby when crossbeam is moved and the force of sliding friction between the column be of moderate size, fit clearance also is of moderate size.
For this reason, the utility model is taked following technical scheme:
A kind of hydraulic locking apparatus of vertical lathe, include crossbeam, column, described crossbeam is provided with hydraulic means, inclined plane slide block and hold down gag, and described hydraulic means is arranged in the head of crossbeam, hold down gag is arranged in the afterbody of crossbeam, and inclined plane slide block is arranged between hydraulic means and the hold down gag; Described hydraulic means includes hydraulic cylinder, piston, piston rod, and the outer end and the inclined plane slide block of described piston rod are affixed; Described hold down gag includes clamp lever, compresses bearing, panelling, stud and holding pin, one end of described clamp lever is provided with the locking wheel that cooperates with inclined plane slide block, the holding pin of the other end and top offsets, be penetrated with described stud on the described clamp lever, the upper end of described stud extends in the crossbeam, the lower end of corresponding stud offers groove on the described clamp lever, is provided with the spheric washer and the taper faced washer of working in coordination in the groove.
Described holding pin is engaged in and compresses in the bearing, compresses bearing and crossbeam is affixed; Be connected with back-up block on the described crossbeam, described inclined plane slide block slides along the lower surface of back-up block.
The outer end of described piston rod is affixed by holding screw and inclined plane slide block.
When piston rod is started working the pulling inclined plane slide block, rising drive locking wheel by the inclined-plane upwards lifts, clamp lever is under this fulcrum of stud, do lever motion by spheric washer, when reaching corresponding coupling mechanism force, travel switch work, the notice digital control system stops hydraulic work system, is in locking state between crossbeam and the column.
Employing the utlity model has following advantage: the coupling mechanism force size between crossbeam and the column can be regulated, when unclamping retaining mechanism, no any clamping force exists between crossbeam and the column, it is minimum that the frictional force of crossbeam and column guide pass reduces to, under the effect of balance cylinder block, crossbeam can be done the easy on and off sliding friction, and the column guide pass wearing and tearing of lathe are little, power consumption is low, the machining accuracy retentivity is good; 2, simple in structure, good stability.
(4) description of drawings
Fig. 1 is the utility model structural representation.
(5) specific embodiment
