Description
Technical field
The invention belongs to a kind of hydraulic press, particularly relate to a kind of clamping structure that can prevent the movable workbench of hydraulic press of workbench local crowning.
Background technology
The formation of hydraulic press includes upper beam, underbeam substantially; Be separately positioned on the pillars at four end angles between upper beam and the underbeam; The lower end of putting the beams in place by suspension arrangement be connected be used for vertical diel, can be along the upper and lower mobile slide block of guide plate that is arranged on two lateral braces; Underbeam is provided with travelling table.Usually, the setting of travelling table be by be separately fixed on four pillars four being connected of angle of end of stepping up device and workbench and with stationary table on underbeam.Because the middle part of workbench is unfixing, when hydraulic press work backhaul, the demoulding is easy to make the middle local crowning that takes place of workbench.
Particularly at present along with large hydraulic press has appearred in industrial expansion, as the appearance of the large hydraulic press of several kilotons.Large hydraulic press for several kilotons, because the increasing of its processing work, the workbench of supporting workpiece will strengthen, if large-scale workbench is still adopted fixed form as above-mentioned prior art, when hydraulic press work backhaul, its mould will inevitably produce the middle danger that local crowning takes place that the demoulding makes workbench to the gravitation of workbench.
Summary of the invention
The present invention provides a kind of clamping structure that can prevent the movable workbench of hydraulic press of workbench local crowning for solving the technical problem that exists in the known technology.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of clamping structure of movable workbench of hydraulic press, include by vertical rib plate and be welded on the workbench that the top panel on the vertical rib plate upper surface is formed, described vertical rib plate lower surface is fixedly connected with the clamping cylinder that prevents the workbench local crowning.
Described clamping cylinder includes: inside is formed with the cylinder body of epicoele and cavity of resorption, be formed with the cavity of resorption hydraulic fluid port in the bottom of cylinder body, side at cylinder body is formed with the epicoele hydraulic fluid port, being provided with in the cylinder body can axially movable piston rod, one end of piston rod is connected with the piston head that only moves in the cavity of resorption of cylinder body, the other end of piston rod is connected with the adpting flange of locating in workbench vertical rib plate lower surface that is used for fixing that is positioned at the cylinder body outside, in the epicoele of cylinder body, also be provided with the guide pin bushing that limits the piston rod moving direction between piston rod and the cylinder body.
Inner port place at cylinder body is formed with the gap between described guide pin bushing and the cylinder body, and this gap has been embedded in cylinder mouth snap ring.
The neighboring of described cylinder body port is formed with the edge, and its edge is provided with the screwed hole that the soket head cap screw that is used for fixing this cylinder body is used.
The lower surface of described vertical rib plate is formed with hole clipping, and described clamping cylinder is entrapped in by the adpting flange with its top in the hole clipping of vertical rib plate lower surface and is fixedly connected on the lower surface of vertical rib plate.
The lower end of described vertical rib plate is provided with a plurality of clamping cylinders that correspondence is distributed in workbench diverse location place.
Advantage and good effect that the present invention has are: because the clamping structure of movable workbench of hydraulic press of the present invention adopts clamping cylinder to be stuck on the vertical rib plate of movable workbench of hydraulic press, and the table top of vertical rib plate and workbench is for being welded to connect, so when hydraulic press work backhaul, oil cylinder is by the travelling backwards of piston rod, hold workbench securely, avoided making the middle danger that local crowning takes place of workbench fully because of the demoulding.And the present invention is simple in structure, and is easy to use, can be used on the various hydraulic press workbench.

The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the clamping structure of movable workbench of hydraulic press of the present invention, enumerate following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, the clamping structure of movable workbench of hydraulic press of the present invention, include by vertical rib plate 1 and be welded on the workbench that the top panel 4 on vertical rib plate 1 upper surface is formed, when four ends of corresponding work top on the vertical rib plate 1 are provided with at need of work travelling table not, be used for the jacking system 2 of jack-up workbench, be not formed with the liftout hole 6 that is used for the processed material thing of jack-up at the center of workbench.In order to prevent when the slider of hydraulic press backhaul,, also be fixedly connected with the clamping cylinder 3 that prevents the workbench local crowning in the lower surface of the vertical rib plate 1 of workbench because of the demoulding causes the workbench local crowning.
As shown in Figure 2, described clamping cylinder 3 includes: inside is formed with the cylinder body 32 of epicoele and cavity of resorption, be formed with cavity of resorption hydraulic fluid port 31 in the bottom of cylinder body 32, side at cylinder body 32 is formed with epicoele hydraulic fluid port 34, being provided with in the cylinder body 32 can axially movable piston rod 39, one end of piston rod 39 is connected with the piston head 40 that only moves in the cavity of resorption of cylinder body 32, the other end of piston rod 39 is connected with the adpting flange of locating in workbench vertical rib plate 1 lower surface 38 that is used for fixing that is positioned at cylinder body 32 outsides, in the epicoele of cylinder body 32, also be provided with the guide pin bushing 35 that limits piston rod 39 moving directions between piston rod 39 and the cylinder body 32.At the inner port place of cylinder body 32, be formed with the gap between described guide pin bushing 35 and the cylinder body 32, this gap has been embedded in cylinder mouth snap ring 36.The neighboring of described cylinder body 32 ports is formed with the edge, and its edge is provided with the screwed hole 37 that the soket head cap screw that is used for fixing this cylinder body 32 is used.Described clamping cylinder 3 is fixed on the sill 41 by screwed hole 37 and screw.
Lower surface in the vertical rib plate 1 of travelling table is formed with hole clipping, and described clamping cylinder 3 is entrapped in by the adpting flange 38 with its top in the hole clipping of vertical rib plate 1 lower surface and is fixedly connected on the lower surface of vertical rib plate 1.Like this, when the slide block of hydraulic press in backhaul, the piston rod 39 that is positioned at the clamping cylinder 3 below the workbench is under the effect of oil pressure, cavity of resorption to clamping cylinder 3 moves, thereby held vertical rib plate 1 tightly, top panel 4 owing to workbench is welded on the vertical rib plate 1 again, so also just firmly fixed top panel 4, and be arranged with the clamping cylinder 3 that a plurality of correspondences are distributed in the workbench diverse location in the vertical rib plate 1 of workbench, so avoided fully the workbench that produced because of the slide block backhaul demoulding in the middle of the danger of local crowning takes place.
