Description
Technical field
The present invention relates to field of machine tool equipment, particularly a kind of workbench is installed the adjustment structure.
Background technology
High speed development along with China's mechanical industry; Especially the development of heavy industry; Demand to large-scale metalworking equipment is more and more, also the technical parameter of equipment is had higher requirement and large-sized work top simultaneously, so just needs the both sides of workbench and mid portion to lay lower margin.Accomplish that the superior installation of lathe on the basis is very difficult, what wherein most be difficult to realize is the good contact rate and the contact stiffness on lathe bed and table base and parallels, Grouting Cement surface.
At present, large and medium-sized bed piece and table base are the supporting of multiple spot parallels mostly, and some improved devices are arranged, but all come with some shortcomings: the one, because there is certain toughness in the fixed position setting of adjusting device, there is position error; The 2nd, owing to the reasons such as structure of design, adjustment is inconvenient.
For the installation of lathe grouting worker method, wherein back-grouting can solve between ground and the adjustable sizing block and not reach the problem that contacts completely, but for large-scale metalworking equipment, the grouting operation of middle lower margin is not very easily.
Lower margin was adjusted structure in the middle of Chinese patent CN200810234501 disclosed a kind of lathe bed, solved the problem that the middle parallels of lathe bed can't be adjusted.
Chinese patent CN200920031593 discloses a kind of adjusting device of stationary work-table; It includes the hollow type hold-down support that is used for fixing on the ground; The top of said hold-down support is connected with an adjustment sleeve that is used to carry, adjust workbench, and the upper end of adjustment sleeve is provided with the adjustment nut that is used to adjust worktable lifting that matches with it; Said stationary work-table adjusting device comprises also from top to bottom that successively through the standing screw of adjustment nut, adjustment sleeve and hold-down support, the upper end of said standing screw is provided with locking nut, and the standing screw lower end links to each other with hold-down support.
Adjustment complex structure in the above-mentioned patent, particularly for large-scale lathe, the fot screw of the centre of workbench is adjusted inconvenience.
In addition, Chinese patent CN200810139270 discloses a kind of secondary grouting construction method of machine setting.For large-scale lathe, the fot screw back-grouting in the middle of this patent work platform is inconvenient.In a word, above-mentioned patent does not all have well to solve the good contact rate and the contact stiffness on workbench and Grouting Cement surface.
Summary of the invention
The objective of the invention is to design a kind of workbench the adjustment structure is installed, solve the inconvenient problem of middle lower margin screw adjusted of platen; Make things convenient for back-grouting; And guarantee that workbench and Grouting Cement surface have good contact rate and contact stiffness.
For achieving the above object, the technical scheme that the present invention adopts is:
A kind of workbench is installed the adjustment structure, comprises workbench and be attached thereto connecing, be fixed on some lower margin fixed blocks in the ground; Offer the installing hole of several open upper end on the described workbench, also offer through hole on the diapire of installing hole; It is characterized in that: each installing hole of corresponding workbench, also comprise, adjust sleeve, be arranged at the diapire through hole of described workbench installing hole, be connected with the diapire through hole whorl; The through hole port is stretched out in adjustment sleeve upper end, and by locking nut locking, stretch out outside the workbench its lower end; Screw rod is arranged in the said adjustment sleeve, and on the adjustment sleeve, the adjustment sleeve is stretched out in the lower end by a nut and washer locking in its upper end; Backing plate is arranged on the ground of corresponding said workbench installing hole, is arranged in the top that is fixed on ground lower margin fixed block; Establish a through hole on the backing plate, the screw rod lower end of stretching out the adjustment sleeve passes that the lower margin fixed block is connected in this backing plate through hole and the ground; Said adjustment sleeve lower end is sheathed on the outer adjustment packing ring of screw rod against backing plate through one.
Further, the through hole top that supplies said screw rod to pass on the described backing plate is processed with the sphere shrinkage pool, and correspondingly, the contact-making surface of adjustment packing ring and sphere shrinkage pool also is a sphere.
Described adjustment sleeve top cross section be shaped as hexagon.
Again, described workbench is provided with the anchor grouting hole, to should the anchor grouting hole, also establishes the grouting through hole on the described backing plate.
Anchor grouting hole on the described workbench and the same import of installing hole.
Anchor grouting hole on the described workbench is positioned at a side of installing hole diapire through hole.
Anchor grouting hole and installing hole entrance point on the described workbench are provided with cover plate.
In addition, establish oil seal ring between cover plate of the present invention and anchor grouting hole and the installing hole inwall.
Described screw rod lower end links to each other through screw thread with the lower margin fixed block.
Described cover plate and oil seal ring are lower than installing hole entrance point port 2 ~ 3mm.
Advantage of the present invention:
1) the present invention can rotate the adjustment sleeve above workbench, particularly can adjust very easily for the fot screw in the middle of the workbench;
2) the anchor grouting hole of design makes Working table structure compact, simple like this, the most important thing is and can above workbench, carry out back-grouting to workbench
3) backing plate floats with the spherical of spherical washer and contacts, thereby can adapt to the nonparallelism of workbench installed surface and foundation surface, makes that each contact-making surface between supporting can fully contact, and has improved contact rate and support stiffness between workbench and ground.
4) adjusting device well combines with the grouting structure, makes the simple in structure of workbench, compactness.
