Abstract
The utility model discloses a compound exchange bracket is chosen in support, including holding in the palm the builder's jack, hold in the palm and choose hook geosynclinal block, workstation, the lift pivot, asking the builder's jack to be the S type for the appearance, being provided with the U type on it and lifting the card, dogging, mounting hole are chosen to arc, 2 the side of hook geosynclinal block symmetry setting at 2 workstation is chosen in individual support to link to each other with the table setting, the support is chosen hook geosynclinal block inside and is provided with round arc -shaped hook vallecular cavity, the workstation bottom is provided with protruding step, the lift pivot is passed the mounting hole and is fixed with holding in the palm the builder's jack, compound exchange bracket is chosen in support has the advantage that two forked type brackets are reliable and stable, bearing capacity is strong simultaneously and colludes the advantage that the type bracket of choosing can be used to the model of cross guide rail, has overcome the shortcoming of two kind current rotatory brackets again: two forked type brackets can not be used for workstation moving direction to be two axial lathes, and it is not high to collude the type of choosing bracket bearing capacity, can not be used for the shortcoming of big -and -middle -sized lathe.
Description
Technical field
This utility model relates to the workbench exchange bracket of lathe, particularly relates to a kind of torr and chooses compound exchange bracket.
Background technology
The platen exchanged form of main flow is rotary at present, and the bracket that this mode is used is usually the following two kinds: double fork cradle and hook choose formula hanger.
Double fork cradle: current modal a kind of exchange bracket, the length direction of bracket has that two U-shaped palette forks are back-to-back is positioned at bracket two, and one of them U-shaped palette fork is positioned at stage travel range.When needing exchange, workbench arrives the appointment position in U-shaped palette fork, and the elevating mechanism within board drives bracket to be lifted by two workbench simultaneously, rotating mechanism drive bracket to rotate 180 ° and replaced by workbench, and then bracket falls, and completes exchange.Double fork cradle are only used for the type that workbench single axial moves, and for the type that movable workbench direction is two axial (decussation guide rails), cannot be able to use because of interference problem.
Hook chooses formula hanger: this exchanged form is, board has the hook plate of a double end, and there is hook and slot the side of two workbench, hooks the plate hook and slot less than workbench side, will not interfere with during lathe normal process.When needing exchange, hook plate and below the hook and slot of the side of two workbench, workbench is provoked.Under the lowering or hoisting gear within board and rotary apparatus drive, complete workbench exchange.Although this bracket can be used for vertical, the workbench exchange of horizontal Machining centers of decussation guide rail, but owing to, in structure, if workbench and workpiece are bigger, heavier, it is abnormally dangerous that this hook chooses mode.So can be used only on the small machines of below workbench 400x400mm.
Summary of the invention
This utility model is for above-mentioned the deficiencies in the prior art, provide a kind of torr and choose compound exchange bracket, vertical, the horizontal Machining centers workbench that thoroughly solve decussation guide rail are exchangeed problem, and are applicable to all size specification, it is achieved workbench quick, reliable exchanges.
For solving problems of the prior art, the concrete technical scheme of employing is:
A kind of torr chooses compound exchange bracket, and including torr builder's jack, torr chooses hook and slot block, workbench；Lift shaft；Described torr builder's jack is that profile is S-type, is provided with U-shaped card of lifting, and circular arc chooses hook card, installing hole；Described 2 torr choose the side that hook and slot block is symmetricly set on the workbench of 2, and are connected with workbench fastening, and torr is chosen hook and slot block and is internally provided with circular arc hook and slot chamber；It is provided with protrusion step bottom described workbench；Described lift shaft is fixed through installing hole and with torr builder's jack.
Preferably technical scheme, described circular arc chooses hook card lateral surface and is circular arc and has certain angle, and medial surface is with step, and circular arc hook and slot chamber and circular arc are chosen hook card geomery and matched；Circular arc choose hook be stuck in circular arc hook and slot intracavity can be freely rotatable.
Further preferred technical scheme, the described U-shaped protrusion step arranged bottom khaki openings of sizes and workbench of lifting matches.
A kind of torr is chosen compound exchange bracket specific implementation process and is:
When workbench needs exchange, it is 90 ° of angles with workbench that torr choose compound exchange bracket to start playback to standby position, torr builder's jack；Then the first step is started: lift shaft drives torr builder's jack to rotate and U-shaped card of lifting is snapped in the protrusion step arranged bottom workbench, and circular arc is chosen hook card and rotated into circular arc hook and slot chamber；Second step: lift shaft begins to ramp up, U-shaped lifts card and circular arc is chosen hook card and worked simultaneously, and workbench is held up；2 workbench exchanges are rotated in place by the 3rd step: lift shaft rotates again；4th step: lift shaft declines, and is in place by workbench；5th step: lift shaft reversely rotates, drives torr builder's jack to screw out workbench, and torr is chosen compound exchange bracket and started again playback to standby position.
By using such scheme, a kind of torr of the present utility model chooses compound exchange bracket compared with prior art, and it has the technical effect that
1. torr is chosen compound exchange bracket and is had the advantage (reliable and stable, bearing capacity is strong) of dual forked type bracket simultaneously and hook the advantage (can be used for the type of decussation guide rail) choosing type bracket, the shortcoming overcoming again existing two kinds of rotary brackets: it is two axial lathes that dual forked type bracket cannot be used for movable workbench direction, it is the highest that hook chooses type bracket bearing capacity, it is impossible to for the shortcoming of big-and-middle-sized lathe.
2. circular arc is chosen hook card lateral surface and is circular arc and has certain angle, and medial surface is with step, and circular arc hook and slot chamber and circular arc are chosen hook card geomery and matched.This fit system enhances the registration performance of whole torr builder's jack, and improves lateral bearing capacity.
3. torr chooses compound exchange bracket, and manufacturing cost is almost identical with dual forked type, produces easily, it is adaptable to produce in enormous quantities.
