Abstract
The utility model relates to a precision coupling structure of high-rigidity machine tool moving working bench and underbeam and is characterized in that the under surface of the panel of machine tool moving working bench is fixed with a supporting guide pillar I by a bolt, the interface of the underbeam is fixed with corresponded amount of supporting guide pillar II corresponding to the position of the supporting guide pillar I, punching through the hydraulic pressure pad of the under beam; the supporting guide pillar II punches through the a tensile pad fixed in the underbeam and is contacted with the supporting guide pillar I, an adjusting pad is arranged between the supporting guide pillar I and the supporting guide pillar II, while a micro clearance exists between the adjusting pad and the supporting guide pillar I. The utility model has the advantages of that the thickness of the up panel of the moving working bench is reduced greatly, thereby not only saving the material, reducing the cost of manufacturing and use, but also improving the precision of assemble dies and guaranteeing the intensity of the machine tool and the processing precision, therefore, the structure has a broad development prospect.
Description
Technical field
The utility model belongs to the Machining Technology field, particularly relates to a kind of large-tonnage sheet stamping, big table top and cost-effective high rigidity lathe travelling table and accurate coupled structure of underbeam of being applicable to.
Background technology
The lathe that has punching press, drawing process at present is in the large format parts machining process, its work mould needs large-tonnage, big table top sometimes and has the travelling table that ejects function satisfies sheet material processing in conjunction with the stretching pad in the following sill bolt needs, be the punching press and the drawing process of sheet material, as outer body covering component of automobile etc.Under lathe large-tonnage duty, the travelling table and the underbeam of carrying mould all will bear very high operating pressure, the existence of pad owing to stretch, determined travelling table to contact with underbeam and the conduct support with periphery, its suffered bending stress maximum in middle part, thereby produce bigger distortion, like this mould and product are all had adverse influence.Increasing along with market demand large-tonnage, big table top lathe, method for designing according to conventional structure, in order to guarantee the travelling table higher-strength, can only be according to ever-increasing pressure, continue to increase the thickness of mobile working deck plate, and the weight of the panel of big table top, thickness 〉=400mm has occupied whole lathe quite great proportion, so caused manufacturing cost significantly to increase, in use in the journey because travelling table need shift out and moves into more mold exchange, because the increase of deadweight also will consume the more energy.
Summary of the invention
The utility model provides a kind of large-tonnage, big table sheet punching stretch and cost-effective high rigidity lathe travelling table and accurate coupled structure of underbeam of being applicable to for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
The accurate coupled structure of high rigidity lathe travelling table and underbeam, it is characterized in that: the panel lower plane at the lathe travelling table is fixed with supporting cell guide I by bolt, be fixed with the supporting cell guide II of respective numbers and break-through underbeam hydraulic die cushion on the underbeam contact-making surface by locknut corresponding to the position of travelling table supporting cell guide I, this supporting cell guide II break-through is crossed the stretching pad that is installed in the underbeam and is contacted with supporting cell guide I, between supporting cell guide I and supporting cell guide II, also be provided with adjusting pad, between adjusting pad and supporting cell guide I, leave the gap, make little last plane that is lower than underbeam, plane on the adjusting pad.
The utility model can also adopt following technical measures:
Described mobile working deck plate lower plane is fixed with and is no less than four supporting cell guides, rationally distributes in the space that the pad upper ejector pin that stretches is arranged.
Described supporting cell guide I cooperates for movingly with adjusting pad on the supporting cell guide II, and promptly the adjusting pad on supporting cell guide I and the supporting cell guide II needs enter duty under travelling table work stressing conditions.
Advantage and the good effect that the utlity model has are: because the utility model all is equipped with supporting cell guide on lathe underbeam contact-making surface and below the travelling table, when lathe mobile working deck plate is out of shape under pressured state, and deflection reaches supporting cell guide I and supporting cell guide II when going up gap width between the adjusting pad, the two closely paste and, supporting cell guide I and supporting cell guide II begin the power of being squeezed, share fractional load, supporting cell guide not only passes to the travelling table fractional load on the underbeam like this, but also can control the deflection of mobile mobile working deck plate, propose to be a kind of novel structure herein, the travelling table middle part is provided with the strong point, the duty lower stress is approximate uniform, travelling table and underbeam can be considered one under this kind state, can solve original travelling table periphery as the problem that supports unbalance stress, under the prerequisite of same required precision and rigidity requirement, can greatly reduce the thickness of lathe mobile working deck plate, can save steel to a great extent, manufacturing and use cost have been reduced, the rigidity and the machining accuracy of lathe also improve a lot, so this structure has comparatively vast potential for future development.
Description of drawings
Fig. 1 is a structural front view of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1; (only representing four supporting cell guides herein)
Among the figure: 1 moves travelling table, 2 bolts, 3 supporting cell guide I, 4 adjusting pads, 5 supporting cell guide II, 6 stretching pads, 7 underbeams, 8 locknuts.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, the accurate coupled structure of high rigidity lathe travelling table and underbeam, panel at travelling table 1 is fixed with four supporting cell guide I 3 below by bolt 2, described supporting cell guide I 3 also can move into or shift out with travelling table, position corresponding to travelling table supporting cell guide I 3 on underbeam 7 contact-making surfaces is fixed with respective numbers supporting cell guide II 5 by locknut 8, by screw fixed adjusting pad 4, and pass the pad 6 that stretches and realize movingly on this supporting cell guide II 5 with supporting cell guide I 3.Described supporting cell guide I 3 and adjusting pad 4 for contacting cooperation, are matched in clearance under the situation that travelling table does not stress under stressed situation; The diameter of described supporting cell guide can be set according to the tonnage of press, the size of work top and the size of the pad that stretches; Gap between adjusting pad 4 and the supporting cell guide I 3 can be determined according to the performance design of lathe.
In dynamic work, after the stressed generation distortion of travelling table, travelling table and underbeam are coupled by the supporting cell guide precision, have increased the bearing capacity of travelling table greatly, have improved the rigidity of travelling table.Reduce the distortion of workbench, effectively raise the machining accuracy of work mould.
