Abstract
The utility model belongs to one kind and can be used for long screw integral supporting structure.Mainly by two slidable lead screw holding nut seats, the compositions such as line slideway auxiliary and connecting rod.Two slidable lead screw support sliding nuts are respectively disposed on two straight-line guide rail slide blocks, are located at the front and back of feed screw nut, feed screw nut is placed on lead screw and is fixedly installed on the table;The connecting rod of distance between fixing two support sliding nuts is provided on support sliding nut at two.This covering device is arranged on bed piece, and lead screw sliding support mechanism is provided on the lead screw in lathe bed, in workbench along the integral rigidity in lathe-bed moving, increasing leading screw, workbench is made to operate steadily on bed piece.
Description
Fields:
The utility model is to belong to heavy machine tool industry, is particularly suitable for light high-speed workbench numerical control dragon mobile over long distances
Door boring and milling machine technical field.
Background technology:
Light high-speed table movable type gantry processor bed, it is longer for workbench.The type of drive of workbench is silk
Bar rotates, feed screw nut's linear motion.In this way in workbench high-speed motion, the lead screw of driving will high speed rotation, due to silk
The supporting way of bar is that both ends fixation supports it to support span very long, and the critical speed that lead screw is reached when the high rotating speed of lead screw will
There is lead screw to swing, causes the operation of work unstable.To influence the running precision of light high-speed gantry milling machine tool.
Invention content:
The purpose of this utility model is to be directed to deficiency in the prior art, proposes that one kind can guarantee that driving lead screw is revolved in high speed
Be not in vibrations and instability problem when turning.By long screw combined support, mechanism can ensure the stable of lead screw,
To ensure running precision of the workbench on lathe bed.
The utility model long screw combined support mechanism, including lead screw, sliding support, connecting rod, the linear guide vice mechanism,
Structure is that the line slideway auxiliary that straight line guide rail and two straight-line guide rail slide blocks are constituted is mounted on lathe bed;Two can slide
Dynamic lead screw support sliding nut is respectively disposed on two straight-line guide rail slide blocks, is located at front and back, the feed screw nut of feed screw nut
It is placed on lead screw and is fixedly installed on the table;It supports to be provided on sliding nut at two and fixes two support sliding nuts
Between distance connecting rod.
Long screw integral supporting structure described in the utility model, because increasing the nut of two sliding supports on long screw
Structure, and be coupled the nut of two sliding supports by connecting rod, ensure the fixed range between two sliding nuts.In two sliding nuts
On the sliding block of lower section and line slideway auxiliary, this integral supporting structure is effectively guaranteed the four-point supporting of long screw, and ensures
Two supporting points can be moved together with workbench.Using two can along the fixed range between the linear guide sliding nut, from
And improve whole root long lead screw integral rigidity.
The utility model has the advantages that reasonable for structure, adjustment is easy for installation, stable structure.It especially can be workbench
Stroke is longer, and requires to ensure under the driving stability of long screw and the working condition of integral rigidity, provides a kind of rational
Solution.
Description of the drawings:
Attached drawing 1:One of long screw combined support mechanism embodiment schematic diagram;
Attached drawing 2:The two of long screw combined support mechanism embodiment schematic diagram.
Specific implementation mode:
Attached drawing 1 and the schematic diagram that attached drawing 2 is long screw integral supporting structure embodiment described in the utility model, two
The view directions of a figure are different.Including lathe bed 1, workbench 2, lead screw 3, front support sliding nut 4, rear support sliding nut
5, feed screw nut 6, preceding straight-line guide rail slide block 7, rear straight-line guide rail slide block 8, the linear guide 9, connecting rod 10.It consists of, straight line is led
Rail 9 is installed on lathe bed 1, and lead screw 3 is placed in the surface on lathe bed 1 and positioned at the linear guide 9,7 He of preceding straight-line guide rail slide block
Straight-line guide rail slide block 8 is arranged in the linear guide 9 afterwards;Feed screw nut 6 matches with lead screw 3, and is installed under workbench 2 (such as
Shown in Fig. 2);Front support sliding nut 4 and rear support sliding nut 5 are respectively disposed on lead screw 3, and positioned at feed screw nut's 6
Front and rear.Before front support sliding nut 4 is placed on straight-line guide rail slide block 7;Rear support sliding nut 5 is placed in rear straight line
On guide rail slide block 8.Front support sliding nut 4 is provided with connecting rod 10 (as shown in Figure 1) with rear support sliding nut 5.To give silk
Bar 6 increases the support of two floatings, improves the rigidity of leading screw.
