Abstract
The utility model discloses a cross beam sliding seat unloading device for a large vertical type turning and milling machine. The cross beam sliding seat unloading device comprises an unloading block and a cross beam unloading guide rail arranged below the unloading block, wherein a moving mechanism for moving the unloading block conveniently is arranged between the cross beam unloading guide rail and the unloading block; the upper end face of the cross beam unloading guide rail is an inclined surface which inclines towards the back side of a cross beam; an included angle (theta) is formed between the upper end face and the horizontal panel and ranges from 0 to 15 degrees; and the lower end face of the unloading block is opposite to the upper end face of the cross beam unloading guide rail. The upper end face of the cross beam unloading guide rail inclines towards the back side of the cross beam, so that unloading in the vertical direction is changed, partial tilting force of a cross beam sliding seat is counteracted, the stress area of the cross beam unloading guide rail is effectively increased, and unloading is relatively steady.
Description
Technical field
The utility model relates to a kind of large-scale vertical milling lathe crossbeam slide relief arrangement.
Background technology
Large-scale vertical milling lathe crossbeam slide off-load original structure is vertical direction off-load roller structure, and is as shown in Figure 1, comprises 1, the crossbeam unloaded slideway, and 2, roller (bearing); 3, bearing pin, 4, the off-load piece, 5, the dish spring; 6, pressing plate, 7, the crossbeam slide, 8, the adjustment bolt; Be used for reducing crossbeam basic rack deflection, improve the basic rack linearity.Existing structure has two weak points, and the one, the vertical direction off-load, large-scale vertical milling lathe knife rest weight is bigger, except gravity makes beam vertical direction distortion, the more important thing is to make the crossbeam distortion of leaning forward, and influences bigger to the Milling Process precision.The 2nd, roller structure, roller is that single line contacts with unloaded slideway, and large-scale vertical milling lathe knife rest weight is bigger, and the local specific pressure of unloaded slideway is excessive, damages guide rail easily.
The utility model content
The purpose of the utility model is to provide a kind of large-scale vertical milling lathe crossbeam slide relief arrangement, to solve the crossbeam distortion of leaning forward, unloaded slideway part specific pressure problems of too.
To achieve these goals, the technical scheme of the utility model is following:
Large-scale vertical milling lathe crossbeam slide relief arrangement; Comprise off-load piece and the crossbeam unloaded slideway that is arranged on off-load piece below; Between crossbeam unloaded slideway and off-load piece, be provided with and be convenient to the travel mechanism that the off-load piece moves, it is characterized in that the upper surface of said crossbeam unloaded slideway is the inclined-plane to the crossbeam rear-inclined; Form an angle theta between said upper surface and the horizontal plane, θ is 0 degree～15 degree; The lower surface of said off-load piece is corresponding with the upper surface of crossbeam unloaded slideway.
In a preferred embodiment of the utility model, said θ is 10 degree.
In a preferred embodiment of the utility model, said travel mechanism comprises the roller guide piece that also can on the crossbeam unloaded slideway, roll that is arranged on off-load piece lower end.
In a preferred embodiment of the utility model, said off-load piece is provided with the adjustment bolt, is provided with the dish spring between off-load piece and the adjustment bolt.
The upper surface of the crossbeam unloaded slideway of the utility model is provided with to the crossbeam rear-inclined, changes the vertical direction off-load, offsets the part crossbeam slide power of tumbling, and has effectively increased crossbeam unloaded slideway lifting surface area, and off-load is more steady.
The utility model changes roller off-load structure, replaces roller (being bearing) with the roller guide piece.Reduce the local specific pressure of crossbeam unloaded slideway, effectively avoid the damage of crossbeam unloaded slideway.
The characteristics of the utility model can consult this case graphic and below better embodiment detailed description and obtain to be well understood to.
Description of drawings
Fig. 1 is the prior art constructions sketch map.
Fig. 2 is the structural representation of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, further set forth the utility model below in conjunction with specific embodiment.
As shown in Figure 2, large-scale vertical milling lathe crossbeam slide relief arrangement mainly comprises off-load piece 40 and crossbeam unloaded slideway 10.Crossbeam unloaded slideway 10 is located at the below of off-load piece 40.
In the utility model, the upper surface 11 of crossbeam unloaded slideway is to the inclined-plane of crossbeam rear-inclined, forms an angle theta between upper surface and the horizontal plane, and θ is 0 degree～15 degree; In the present embodiment, θ is 10 degree.The lower surface of off-load piece 40 is corresponding with the upper surface of crossbeam unloaded slideway.This structure can change the vertical direction off-load, offsets part crossbeam slide 60 power of tumbling, and has effectively increased crossbeam unloaded slideway lifting surface area, and off-load is more steady.
Between crossbeam unloaded slideway 10 and off-load piece 40, be provided with and be convenient to the travel mechanism that the off-load piece moves, this travel mechanism comprises roller guide piece 21.On crossbeam unloaded slideway 10, be installed with steel band 12, roller guide piece 21 can roll on steel band 12.Through changing roller off-load structure, replace roller (being bearing) with the roller guide piece.Reduce the local specific pressure of crossbeam unloaded slideway, effectively avoid the damage of crossbeam unloaded slideway.
In addition, off-load piece 40 is provided with adjustment bolt 50, is provided with dish spring 30 between off-load piece 40 and the adjustment bolt 50.Decrement through adjustment bolt 50 adjustment dish springs 30.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The just principle of describing in the foregoing description and the specification of the utility model; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the scope of the utility model that requires protection.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
