Description
Technical field
The present invention relates to Digit Control Machine Tool field, the crossbeam combination on especially a kind of Digit Control Machine Tool.
Background technology
Current existing cross beam of numerical control machine structure adopts linear guide apparatus more. Linear guides is arranged on the guide rails assembling seat of crossbeam, and the design of guide rails assembling seat is varied: two guide rails assembling seats are all on the same vertical plane of crossbeam, one on the other; Or two guide rails assembling seats lay respectively on the vertical plane of crossbeam and on horizontal plane, or be equipped with two guide rails assembling seats on front and back two vertical planes of crossbeam; Then on guide rails assembling seat, refilled linear guides, ram links together by the slide block on it and linear guides, is subject to the effect of pulling force F1 at upper linear guides, under the be under pressure effect of F2 of linear guides, as shown in Figure 5. Traveller is housed on ram, due to long-term cutwork, traveller center line and vertical direction have produced certain angle, under the pressure F2 that is subject to of linear guides increase, under the impact of tensile force f 1 and the long-term alternation of pressure F2, linear guides unbalance stress, the Stiffness of linear guides, shorten service life, stability decreases, and machining accuracy is affected.
Summary of the invention
The object of this invention is to provide the crossbeam combination on a kind of Digit Control Machine Tool.
What the present invention solved is that existing machine tool guideway mount pad design is unreasonable, causes linear guides combination rigidity to decline, and shorten service life, the problem of stability decreases.
The technical scheme that the present invention solves its technical problem employing is: the present invention includes cross-beam body and ram, ram is positioned at the front of cross-beam body; On front and back two vertical planes of described cross-beam body, be equipped with guide rails assembling seat, on guide rails assembling seat, linear guides be housed; Front described ram is provided with adjutage, and adjutage is crossed the top of cross-beam body, is connected with the linear guides on vertical plane upper rail mount pad after cross-beam body by the slide block being contained on adjutage.
The invention has the beneficial effects as follows: the present invention compared to the prior art, on the rear vertical plane of crossbeam, increase by the 3rd linear guides, adjutage on ram is crossed crossbeam, be connected with the 3rd linear guides by the slide block on it, act on like this effect that the 3rd linear guides on rear vertical plane is under pressure, act on the effect that first, second linear guides on front vertical plane is also under pressure, and the opposite direction that is under pressure of the 3rd linear guides on direction and rear vertical plane, makes linear guides composite entity in very stable state. In order to keep the depth of parallelism of the linear guides on linear guides and the front vertical plane on rear vertical plane, between the slide block on adjutage and adjutage, be provided with nonmetal spring, be used for ensureing the depth of parallelism between the first linear guides and the 3rd linear guides. Design of the present invention, has improved the Rigidity and strength of crossbeam composite entity, has ensured the precision of processing.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, Figure 2 and Figure 3, in the present embodiment, the present invention includes cross-beam body 1 and ram 7, ram 7 is positioned at the front of cross-beam body 1; On front and back two vertical planes of cross-beam body 1, be equipped with guide rails assembling seat, front vertical plane is provided with two guide rails assembling seats, is respectively the first guide rails assembling seat 11 and the second guide rails assembling seat 10; The rear vertical plane of cross-beam body is provided with a 3rd guide rails assembling seat 12.
On guide rails assembling seat, linear guides is housed; The quantity of guide rails assembling seat and linear guides is corresponding, and linear guides comprises the first linear guides 5, the second linear guides 9 and the 3rd linear guides 2. Corresponding the first linear guides 5 of the first guide rails assembling seat 11, corresponding the second linear guides 9 of the second guide rails assembling seat 12 and corresponding the 3rd linear guides 2 of the 3rd guide rails assembling seat 12.
The first guide rails assembling seat 11 of the 3rd guide rails assembling seat 12 of cross-beam body 1 rear vertical plane and cross-beam body 1 front vertical plane, the second guide rails assembling seat 10 are parallel between two, and the 3rd described linear guides 2 and the first linear guides 5, the second linear guides 9 are also parallel between two.
Ram 7 is provided with adjutage 4, and adjutage 4 is crossed the top of cross-beam body 1, is connected with the 3rd linear guides 2 on the rear vertical plane of cross-beam body 1 by the slide block 3 being contained on adjutage 4. Adjutage 4 and be contained between the slide block 3 on adjutage and be provided with nonmetal spring 13, nonmetal spring 13 one end are fixed on adjutage 4 by double-screw bolt 14, and the other end and slide block 3 offset, as shown in Figure 4. Nonmetal spring 13 adopts polyurethane material to make, and the spring of this material has very high elasticity, good wearability and damping characteristic. Because the depth of parallelism between the first linear guides 5 and the 3rd linear guides 2 is difficult to ensure, regulate the depth of parallelism between the two by nonmetal spring 13.
The first linear guides 5 and the second linear guides 9 link together by being arranged on slide block 6 on ram 7 and slide block 8 and ram 7 respectively.
The present invention on the basis of existing technology, on the rear vertical plane of crossbeam 1, increase by the 3rd linear guides 2, adjutage 4 on ram 7 is crossed crossbeam 1, be connected with the 3rd linear guides 2 by the slide block 3 on it, apply a pressure F3 to like this 3rd linear guides 2, meanwhile, the first linear guides 5 becomes pressure F1 ' from the tensile force f 1 being originally subject to, as shown in Figure 6. Finally the power on the crossbeam line rail of effect is pressure, and linear guides is in very stable state, and such action effect has improved the Rigidity and strength of crossbeam composite entity, has also ensured the precision of processing.
