Description
Technical field
The utility model relates to drilling machine, relates in particular to a kind of box type vertical drilling machine main-axle box elevating mechanism.
Background technology
The main spindle box elevating mechanism of box type vertical drilling machine has two kinds of popular mechanisms at present: the one, and the domestic logical manual lifting mechanism of seeing; The 2nd, external motor elevator structure commonly used.The cardinal principle of manual lifting mechanism is a stationary rack on column, and gear (with tooth bar engagement) and worm gear are housed at the main spindle box rear portion, shakes worm-drive worm screw and in-line gears thereof and drives main spindle box along the column lifting rail with handle; The cardinal principle of motor elevator structure is to drive to screw mandrel at column top dress motor and gear reduction box, and nut is fixed on the main spindle box rear portion, and the screw mandrel rotation is after nut drives the main spindle box lifting.
Manual lifting mechanism is for motor-driven lifting, and structure is comparatively simple, but by human control, it is time-consuming to require great effort, and handle power is all greater than 10kg, and rising or falling speed is slow, especially be raised to certain altitude after, operate more difficultly, labour intensity is bigger.
The motor elevator structure has well solved the big problem of labour intensity, but structure is comparatively complicated, moment of torsion insurance zygote and lubricant method and anti-seep measure also must be arranged, its outward appearance is also relatively poor, especially the lathe height increases to packing, conveyer belt has any problem, in order to reduce the packing case height, also must unload and load onto motor again after motor waits to transport to the user installation scene.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, operation is safer, the main spindle box elevating mechanism of the box type vertical drilling machine being convenient to transport.
The technical solution adopted in the utility model is:
The box type vertical drilling machine main-axle box elevating mechanism, comprise motor and screw mandrel, described motor is inverted on the interior motor cabinet of drilling machine lathe bed, be connected with screw mandrel with negative pulley wheel through drive pulley, described screw mandrel is parallel to the drilling machine column guide rail, the upper and lower side that described screw mandrel connects the column guide rail is provided with upper bearing (metal) assembly and lower bearing component, and thread bush is connected to the lock nut assembly on the described screw mandrel, and described lock nut assembly is fixedlyed connected with drilling head.
Described lock nut assembly comprises mother nut, secondary nut, gland, nut seat and steel ball,
Described mother nut is set in the nut seat, and described gland is fixed on the nut seat by screw, and sphere contacts between mother nut and the gland,
Described mother nut is provided with the end face breach, and inserts this breach by pin and be fixed on the nut seat,
The protruding key of the end face of described mother nut flexibly connects with the corresponding end face groove of secondary nut that is set in the nut seat,
Be provided with the steel ball groove between described secondary nut and the gland, described steel ball trench bottom is provided with a circle steel ball.
Distance in described steel ball groove top and the groove between the steel ball top greater than between protruding key base portion of mother nut end face and the secondary nut end face bottom portion of groove apart from 5-10mm.
In lathe bed, the pressing plate that passes in the lathe bed by screw is vertically fixed in the lathe bed motor cabinet by the stretching screw crosswise fixed.
In the utility model motor is inverted on the motor cabinet in the drilling machine lathe bed, and adopt drive pulley and negative pulley wheel to drive screw mandrel and rotate, described screw mandrel is parallel to the drilling machine column guide rail, the upper and lower side that described screw mandrel connects the column guide rail is provided with upper bearing (metal) assembly and lower bearing component, thread bush is connected to the lock nut assembly on the described screw mandrel, described lock nut assembly is fixedlyed connected with drilling head, above-mentioned structure is the structure that does not have at present, and greatly reduce the height of parts, improved processing safety.Sphere contacts between mother nut and the gland, bear axial force and regulate rigging error voluntarily, pin inserts and makes the unlikely rotation of mother nut in its end face breach, when screw mandrel rotates, mother nut and nut seat are with the main spindle box lifting jointly, secondary nut flexibly connects by its end face groove and the protruding key of the end face of mother nut, and the pair nut is servo-actuated and do not bear driving torque when elevating movement.In case mother nut wear and rupture, main spindle box will inevitably drop, at this moment, circle steel ball in the steel ball groove can contact the thrust ball bearing effect of playing with the gland inner face, protruding key, the groove of major and minor nut are thrown off voluntarily simultaneously, since the distance in steel ball groove top and the groove between the steel ball top greater than between protruding key base portion of mother nut end face and the secondary nut end face bottom portion of groove apart from 5-10mm, in this case, even screw mandrel also can not drive the main spindle box lifting again rotating.So when mother nut damaged, no matter whether screw mandrel rotated, main spindle box all only can fall very small distance and can not drop significantly.Described upper bearing (metal) assembly is made up of deep groove ball bearing and thrust ball bearing, and the upper bearing (metal) assembly has played supporting, born the effect of main spindle box body weight.Described lower bearing component is two angular contact ball bearings of isolate installing in the same way, can support, the component that makes progress when bearing the screw mandrel transmission.
Motor is by the structure of belt driving band movable wire bar, lock nut lifting main spindle box in the lathe bed of column of the present utility model bottom, simple in structure, easy-to-operate, be easy to the container transportation, outward appearance is more succinct, reduce working strength of workers greatly, improved operating efficiency.
