Description
Technical field
The present invention relates to a kind of heavy removable click-on mechanisms, belong to machine tool technology field.
Background technique
In current China machine industry, the chuck jaw dimensions of heavy CNC vertical turning machine is larger, heavier-weight.Very much
Heavy CNC vertical turning machine is in order to guarantee the reliability of clamping, or even using heavy reinforcement chuck jaw.When operator is loaded work
When part, heavy chuck pawl is depended merely on manpower and can not be moved at all, after can only lifting by crane claw by overhead traveling crane, moves again to corresponding position
Set, thus the workpiece of heavy CNC vertical turning machine be loaded it is more time-consuming, especially when processing when need to frequently replace workpiece
When, the cumbersome process of being loaded can consume many manpower and material resources.
Summary of the invention
In order to solve above-mentioned the shortcomings of the prior art, the present invention provides a kind of heavy removable click-on mechanism, bottoms
Portion is set there are four Mobile support device, when claw screw unclamps, the disk spring of Mobile support device by its needle bearing to
It pushes, makes below needle bearing lower than claw in the following, making needle bearing play the role of wheel hub, when moving heavy claw in this way
By Manual-pushing, the time that is loaded is saved, is improved work efficiency.
The technical solution adopted by the present invention to solve the technical problems is: a kind of heavy removable click-on mechanism, including rolling
Needle bearing, locating shaft, positioning sleeve, adjusting pad, butterfly spring, screw, lock screw, T-slot screw, nut, master jaw, claw
And adjustment screw, master jaw bottom are surrounded by T-slot screw, T-slot screw is equipped with and can be lived by nut adjustment, master jaw
Dynamic claw is equipped with the adjustment screw that claw is fixed between master jaw and claw, master jaw bottom four, T-slot screw is outer
Side is set there are four Mobile support device, opens up that there are four cylinder grooves on the outside of the T-slot screw of master jaw bottom four, in claw
The surface of seat top cylindrical slot offers the counter sink being connected to its slot inner chamber body, is equipped with cylindrical type in cylinder groove and positions
Set, positioning sleeve top are equipped with adjusting pad, and screw is inserted into counter sink rear thread and screws in positioning sleeve, in cylinder groove above adjusting pad
Equipped with the butterfly spring on screw is covered, rectangular channel is offered in positioning sleeve bottom, is equipped with needle bearing, positioning sleeve in rectangular channel
Needle bearing is limited in rectangular channel by locating shaft, needle bearing bottom end is lower than positioning sleeve bottom end, in the side wall of positioning sleeve
On offer the sliding slot of a longitudinal direction, be equipped with the lock screw in the sliding slot that end thread screws in positioning sleeve in master jaw side wall,
Lock screw limitation positioning sleeve rotates in the cylinder groove of master jaw.
Master jaw is put into T-shaped groove of working table by T-slot screw and is moved, and when the nut 34 is tightened, needle bearing is pressed into
In the cylinder groove of master jaw, butterfly spring stress and elastic deformation occurs.Master jaw is fixed on work by T-slot screw at this time
Make on platform, the work of card engaging workpiece can be carried out by claw.When needing to dismantle workpiece movement claw, nut is unclamped, it is dish-like
Spring restores former long, and elastic force makes needle bearing be lower than master jaw bottom surface, at this time the four of master jaw bottom surrounding needle bearing branch
Support entire master jaw.When mobile jaw body, four needle bearings of master jaw bottom surrounding are distributed in using locating shaft as axle center
Rotary motion can be achieved with jaw body moving along T-slot direction by man-driven in this way.Lock screw is used to limit positioning
Set, prevents in moving process, and positioning sleeve rotates, and so as to cause needle bearing rotation, hinders the movement of jaw body.Positioning
Set is fixed on master jaw by screw, prevents it from falling.
The beneficial effects of the present invention are: the removable claw actuator base of this heavy type is set, there are four Mobile support device, the shiftings
Movable support device is fixed using four needle bearings as wheel hub, and with locating shaft.Needle bearing relies on positioning sleeve by bearing axis
It is positioned to direction.It is adjusting pad above positioning sleeve, when assembly adjusts the position of needle bearing, passes through screw and adjusting pad, guarantees
When spring relaxation state, needle bearing can be mobile lower than claw is carried out below claw.Dish-like bullet is placed above adjusting pad
Needle bearing is pressed above workbench upwards when the locking of claw screw, compresses disk spring by spring, below needle bearing with
It is same plane below claw.When claw screw unclamps, disk spring is dish-like due to overcoming elastic deformation to need to restore former long
Needle bearing will be pressed downward by spring at this time, be made below needle bearing lower than claw in the following, needle bearing plays the work of wheel hub
With, so mobile heavy claw when lean on Manual-pushing, eliminate the complicated processes for lifting claw repeatedly, shorten operator
The time of member's card engaging workpiece, improve the working efficiency of heavy machine tool processing.
