A kind of travelling table of hydraulic press
Technical field
The utility model relates to the travelling table of a kind of hydraulic press, particularly a kind of hydraulic press.
Background technology
At present, public hydraulic press has mostly adopted removable workbench, made things convenient for mould and workpiece installation, clamping and replacing, reduced working strength of workers, improved operating efficiency, promoted the automaticity of operation, strengthened device ', but there are problems in present several travelling table drive units: the installation difficulty that has, the user need excavate the melt pit of number Mi Shen, the unstable properties that has, have because profile influences workman's normal running, what have influences equipment appearance.
The utility model content
The technical problems to be solved in the utility model provides a kind of travelling table of hydraulic press.
For solving the problems of the technologies described above, the utility model is the travelling table of hydraulic press, constitute by flexibly connecting travelling table on the workbench, be fixed with tooth bar on the described travelling table, stationary table is connected with floats cylinder, and floating the cylinder top has guide pillar, gear shaft is housed in the guide pillar, guide pillar is fixed in the axle sleeve, described axle sleeve with float cylinder and be connected, it is characterized in that: the travelling table drive unit that also is provided with pinion and rack between described travelling table and the workbench.
Described travelling table drive unit is equipped with minor sprocket by the hydraulic motor that is fixed in the workbench leading flank on the hydraulic motor, minor sprocket is connected and forms with hinge wheel with chain.
Described hinge wheel is enclosed within on the gear shaft, and gear shaft is fixed in the guide pillar,, gear and the tooth bar on the travelling table on the described guide pillar are in meshing state all the time.
The advantage of above structure is: described travelling table drive unit has strengthened the stationarity of travelling table, has reduced the equipment installation difficulty, has improved device ', has further improved production efficiency.
Description of drawings
Be illustrated as structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
As shown in the figure, be fixed with on the described workbench 1 and float cylinder 2, float cylinder 2 tops and be connected with guide pillar 3, describedly float cylinder 2 and all be contained in the bearing 4 with guide pillar 3.Angular contact ball bearing 5 is housed in guide pillar 3, set gear axle 6 on the angular contact ball bearing 5, gear 7 is equipped with at described gear shaft 6 two ends.Guide pillar 3 and gear shaft 6 move up and down by floating cylinder 2.It more than is the dependency structure of workbench.
Tooth bar 9 and roller 10 are housed on the described travelling table 8, described gear shaft 6 is connected and composed with coupling sleeve 11 by major axis and minor axis, be with hinge wheel 12 on the described minor axis, minor sprocket 13 is enclosed within on the hydraulic motor 14, described hydraulic motor 14 is fixed on workbench 1, guarantee normally carrying out of hydraulic press compacting work, described workbench 1 two ends also are provided with hold down gag 15.
When hydraulic press was in the compacting duty, travelling table 8 was close on the workbench 1, and this hour rack 9 and gear 7 are in engagement, be enclosed within big minor sprocket 12, chain on 13 is in releasing orientation, floats cylinder 2 and is in pressed status, and roller 10 is floated by guide pillar 3 and supporting.
When hydraulic press compacting finishes more mold exchange, unclamp hold down gag 15, describedly float cylinder 2 and eject guide pillar 3, this moment described guide pillar 3 withstand roller 10 upwards and driven gear 7 make progress synchronously, gear 7 and tooth bar 9 still are in engagement, travelling table 8 upwards is lifted away from workbench 1, travelling table 8 is supported by roller 10 fully, described chain is in the tensioner state, open hydraulic motor 14, minor sprocket 13 drives hinge wheel 12, and then makes gear 7 drive tooth bar 9, reach the purpose that travelling table 8 is shifted out workbench 1, wait to unload workpiece or more finish changing mould propelling more later on.
