Description
Technical field
The present invention relates to hydraulic press, relate in particular to a kind of high precision horizontal hydraulic machine.
Background technology
Hydraulic press is a kind ofly to take liquid as working media, according to pascal's principle, make for transferring energy to realize polytechnic machine, utilize hydrostatic pressure to carry out the goods such as processing metal, plastics, rubber, timber, powder.Press the direction of active force and distinguish, hydraulic press has vertical and horizontal two kinds, and most hydraulic presses are vertical, push multiplex horizontal with hydraulic press.
The punching press power part that vertical hydraulic press is used is also vertical, and the active force that hydraulic power parts produce is identical with the direction of gravity, and workpiece is extruded in counterdie.But for the larger workpiece of length, the hydraulic press processing of vertical is cumbersome, hydraulic power parts are longer in vertical displacement, the vertical fixing height of workpiece is larger, this vertical support is a larger burden, and whole height is too high, make to move in the center of gravity of equipment less stable.Height space requirement vertical during layout is high, causes operation inconvenience.
The principal character of horizontal hydraulic machine is the horizontal installation of master cylinder, it is the axis horizontal of master cylinder, workbench working face is vertical with horizontal plane, master cylinder band movable slider is done the motion of horizontal direction, its guide frame is different from the vertically arranged hydraulic press of conventional master cylinder, the conventional hydraulic press master cylinder direction of motion is parallel to movement parts gravity direction, relies on guide ring, fairlead guiding in master cylinder can meet guiding requirement.And horizontal hydraulic machine is different, its master cylinder axis and horizontal plane due to slide block and the deadweight meeting shape that is connected to the mould on slide block in an angle, and along with the stretching out of master cylinder, this angle can increase, and then cause piston rod upper and lower side unbalance stress, easily cause piston rod one layback hair wearing and tearing.General four guide colume types or the wedge guide rail structure of adopting of slider guide structure of traditional horizontal hydraulic machine.In horizontal guide pillar slider of hydraulic press motion process, deadweight can cause the distortion of guide pillar, and has increased frictional force between guide pillar, guide pin bushing; Wedge guide rail structure guiding accuracy is good, bearing capacity is strong, but cost of manufacture is high, and guiding accuracy is difficult to be regulated, and assembling needs reconditioning repeatedly just can reach required precision.
Summary of the invention
The technical assignment of technical problem to be solved by this invention and proposition is that prior art is improved, and a kind of high precision horizontal hydraulic machine is provided, and the horizontal hydraulic machine guiding solving in current technology is easy to wear, the difficult problem regulating of guiding accuracy.
For solving above technical problem, technical scheme of the present invention is:
A kind of high precision horizontal hydraulic machine, comprise hydraulic cylinder, it is characterized in that, the axial maintenance horizontal device of described hydraulic cylinder on hydraulic cylinder pedestal, the right side of hydraulic cylinder base unit table base, the left-hand unit top beam of hydraulic machine of table base, on the cylinder head of hydraulic cylinder, install hydraulic press sliding shoe, table base laying apparatus guideway, the bottom of hydraulic press sliding shoe arranges slide block, and slide block is slidably matched along guideway.High precision horizontal hydraulic machine of the present invention does not adopt traditional column that utilizes to lead, but install slide block and guideway below the hydraulic press sliding shoe being connected on hydraulic cylinder cylinder head, coordinate and realize guide effect, thereby slideway auxiliary device is guaranteed the precision of stability and the guiding of guideway on table base, guarantee that guiding can not be offset, slide block slides and has guaranteed the accuracy that hydraulic press sliding shoe moves along guideway, thereby effectively improves the guiding accuracy of whole hydraulic press.
Further, described guideway adopts ball-type linear slide guideway, and slide block adopts the ball-type linear slide block matching.Utilize ball-type linear slide guideway from sliding friction, to change traditional guiding friction mode into rolling friction, not only coefficient of friction is low to moderate 1/50 of the guiding of sliding, it is very little that the gap of kinetic force of friction and stiction also becomes, effectively reduce wearing and tearing, therefore when slide block moves, do not have the phenomenon of creeping and skidding and occur.
Further, described guideway adopts four row formula list circular arc tooth form contact line slideways, possesses four directions to the function that waits load character and automatic aligning, can absorb the rigging error of installed surface, reach high load capacity, high-precision requirement, can reach the positioning and guiding precision of μ m level.
Further, the bottom of described hydraulic press sliding shoe is connected with slide block by connecting plate, increases connecting plate and can facilitate the handling of slide block to safeguard, guarantees the dimensional accuracy of assembling.
Further, on described guideway, returning apparatus has protective cover, effectively protects greasy dirt, iron filings, foreign material etc. and falls into and on guideway, damage the normal smooth guiding that guideway affects guideway, improves the service life of guideway.
Further, described protective cover is steel plate extension-type shelter, be not afraid of that hard thing collides, not yielding, the life-span long, good seal and operation light, and guard shield stroke is long, compresses little.
Further, between described hydraulic cylinder pedestal and top beam of hydraulic machine, be also connected with column, column does not play slider guide effect here, but connects pedestal and entablature, by adjusting bolt, plays a part connection, pretension and spacing.
Further, on described hydraulic cylinder pedestal and top beam of hydraulic machine, returning apparatus has grating scale, grating scale is the length measuring instrument with coded system output by dynamic displacement measurement, can effectively detect the displacement of hydraulic press sliding shoe transverse shifting, thereby improves the machining accuracy of hydraulic press.
Compared with prior art, the invention has the advantages that:
Guiding when high precision horizontal hydraulic machine of the present invention adopts ball-type linear slide guide rail to coordinate with ball-type linear slide block to realize hydraulic press running, from sliding friction, change traditional guiding friction mode into rolling friction, coefficient of friction is low to moderate 1/50 of the guiding of sliding, it is very little that the gap of kinetic force of friction and stiction becomes, therefore when slide block moves, do not have the phenomenon of creeping and skidding and occur;
Wearing and tearing while effectively reducing guiding, in the service life of improving hydraulic press guide system, have also improved guiding accuracy simultaneously greatly;
The present invention is simple in structure, and cost of manufacture is low, easy to operate, long service life, and economic benefit is high.
