With respect to prior art, the utility model has been obtained following beneficial effect: the middle part of crossbeam is to be out of shape maximum position downwards, at the end face middle part of crossbeam, pull bar contact seat is set, and upwards mention by double thread brace symmetry, can offset the distortion that crossbeam gravity causes, and As time goes on, can also regulate the pretension of double thread brace.
As improvement of the present utility model, described pull bar contact seat is up-small and down-big isosceles trapezoid, is arranged with contact seat screwed hole on the contact seat inclined-plane of the pull bar contact seat left and right sides; The top of two pull bar columns is arranged with the pull bar column inclined-plane tilting to the center position of described crossbeam, and described pull bar column is arranged with pull bar column screw hole on inclined-plane, described contact seat screwed hole and corresponding pull bar column screw hole coaxial line; The lower end of described double thread brace is screwed in respectively in described contact seat screwed hole and fixes by nut, and the upper end of described double thread brace is passed respectively described pull bar column screw hole and is fixed on corresponding pull bar column inclined-plane by nut. When installation, double thread brace is through the pull bar column screw hole on pull bar column inclined-plane, then lower end screws in contact seat screwed hole and screws nut lower end is fixed, then screw gradually nut in the upper end of double thread brace, make the equal pretension of the symmetrical generation of two double thread braces.
As further improvement of the utility model, the nut below of described double thread brace upper end is respectively equipped with pad, between described pad and corresponding pull bar column inclined-plane, is respectively equipped with dish spring. Add dish spring, can prevent that overlong time from causing double thread brace to lose efficacy, and ensures that double thread brace is reliable for a long time.
As further improvement of the utility model, the axis of described double thread brace is respectively perpendicular to corresponding contact seat inclined-plane. Get in touch with the easy to process of seat screwed hole, and the force-bearing situation of double thread brace is best.
As further improvement of the utility model, the root periphery of described pull bar column is respectively equipped with compensating groove, and described compensating groove is respectively along the vertical axis of machine pillar to downward-extension. Produce after pretension at double thread brace, the upper end of pull bar column can produce the pulling force towards crossbeam, make pull bar column itself produce flexural deformation, between the root periphery of pull bar column and machine pillar, separate by compensating groove, make pull bar column produce certain elasticity, pull bar column only has bottom and is connected with machine pillar, thereby makes the distortion of pull bar column not affect machine pillar.

Detailed description of the invention
As shown in Figures 1 to 8, the Longmen machine tool that the utility model beam deformation is little comprises the machine pillar 1 that stands on workbench both sides, the top of two machine pillars 1 is connected with crossbeam 2, the end face outside of two columns is arranged with the pull bar column 3 protruding upward, the top that the end face middle part of crossbeam 2 is provided with pull bar contact seat 4, two pull bar columns 3 is connected with pull bar contact seat 4 by double thread brace 5 respectively.
Pull bar contact seat 4 is up-small and down-big isosceles trapezoid, is arranged with contact seat screwed hole on the contact seat inclined-plane of pull bar contact seat 4 left and right sides; The top of two pull bar columns 3 is arranged with the pull bar column inclined-plane tilting to the center position of crossbeam 2, is arranged with pull bar column screw hole on pull bar column inclined-plane, contact seat screwed hole and corresponding pull bar column screw hole coaxial line; The lower end of double thread brace 5 is screwed in respectively in contact seat screwed hole and fixes by nut, and the upper end of double thread brace 5 is passed respectively pull bar column screw hole and is fixed on corresponding pull bar column inclined-plane by nut.
The middle part of crossbeam 2 is to be out of shape maximum position downwards, at the end face middle part of crossbeam 2, pull bar contact seat 4 is set, and upwards mention by double thread brace 5 symmetries, can offset the distortion that crossbeam gravity causes, and As time goes on, can also regulate the pretension of double thread brace 5. When installation, double thread brace 5 is through the pull bar column screw hole on pull bar column inclined-plane, then lower end screws in contact seat screwed hole and screws nut lower end is fixed, then screw gradually nut in the upper end of double thread brace 5, make the equal pretension of the symmetrical generation of two double thread braces 5.
