Abstract
The utility model provides a longitudinal gapless meshing mechanism of a gantry numerical control cutting machine. The technical scheme is that the longitudinal gapless meshing mechanism comprises a drive support, wherein the drive support is used for fixing a column of the drive support, one end of the drive support is fixed on the column through a rotary shaft, and the other end of the drive support is fixed on the column through an elastic gap eliminating mechanism. The mechanism can enable a gear and a rack to be meshed well, prevent a 'stuck' phenomenon, improve the stationarity in operation, ensure the cutting precision and cutting quality and prolong the service life of the gear and the rack.
Description
Technical field
The utility model relates to a kind of numerical-controlled gantry cutting machine, the vertical tight mesh of especially a kind of numerical-controlled gantry cutting machine mechanism.
Background technology
In the prior art, known technology is one of numerical-controlled gantry cutting machine main cutting mode of having become sheet material, can satisfy different process requirements, have widely market, numerical-controlled gantry cutting machine promotes the crossbeam motion with the rack-and-pinion transmission mostly, the driving mechanism that driven wheel is arranged in the column of crossbeam, the support two ends of present driving mechanism mostly are fixed together with column, like this when column when the tooth bar on guide rail moves, in case when running into tooth bar projection or depression, will be stuck, reduced the lathe traveling comfort, and affect service life of rack-and-pinion, reduced cutting accuracy and cut quality, but this existing weak point that is prior art.
Summary of the invention
The purpose of this utility model is exactly for the existing deficiency of prior art, and provide the technical scheme of the vertical tight mesh of a kind of numerical-controlled gantry cutting machine mechanism, the mechanism of this scheme can make gear and tooth bar well mesh, prevent " stuck " phenomenon, promote traveling comfort, guarantee cutting accuracy and cut quality, and prolonged the service life of gear and tooth bar.
This programme is achieved by the following technical measures: the vertical tight mesh of a kind of numerical-controlled gantry cutting machine mechanism, comprise driving arm, the column that is used for the fixed drive support, the characteristics of this programme are: an end of described driving arm is fixed on the column by turning cylinder, and the other end of driving arm is fixed on the column by elastic gap-eliminating mechanism; Described elastic gap-eliminating mechanism comprises the limited post that is arranged on the driving arm top and bottom, described limited post is fixed on the column, limited post can be bolted on the column, also can be fixed on the column by the mode of welding, limited post can be bearing, also has a lead that is fixed on the column, and described lead passes driving arm, be provided with anti-backlash between lead and the driving arm, described lead can be bolt.
Described turning cylinder is fixed on the column by the plate joint, and the plate joint is fixed on the column by hold-down screw, also is provided with a plurality of adjustment screw on the plate joint.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because driving mechanism is arranged on the driving arm in this scheme, one end of driving arm is fixed on column by turning cylinder, and the family of driving just can rotate in the horizontal direction around turning cylinder like this; Turning cylinder is fixed on the column by the plate joint, and the plate joint is fixed on the column by hold-down screw, effectively fixed bias circuit; Limited post in the driving arm top and bottom, described limited post is fixed on column, can avoid like this movement of driving arm in the vertical direction, no matter in starting equipment or equipment running process, the driving arm in the vertical direction can not be offset, and has avoided miscut; Lead is fixed on the column, and lead passes driving arm, be provided with anti-backlash between lead and the driving arm, when running into raised or sunken tooth bar, under the effect of spring, gear still can effectively mesh with tooth bar, has avoided " stuck ", has guaranteed cutting accuracy and cut quality.This shows that the present invention compared with prior art has outstanding substantive distinguishing features and significant progressive, the beneficial effect of its enforcement also is apparent.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Fig. 2 is the structural representation of elastic gap-eliminating mechanism.
Among the figure, 1 is driving arm, and 2 is column, and 3 is turning cylinder, and 4 is limited post, and 5 is lead, and 6 is the plate joint, and 7 is hold-down screw, and 8 is adjustment screw, and 9 is driving mechanism, and 10 is gear, and 11 is guide rail, and 12 is tooth bar, and 13 is anti-backlash.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by a specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
Can find out by accompanying drawing, the vertical tight mesh of the numerical-controlled gantry cutting machine of this programme mechanism, comprise driving arm 1, the column 2 that is used for fixed drive support 1, one end of described driving arm 1 is fixed on the column 2 by turning cylinder 3, and the other end of driving arm 1 is fixed on the column 2 by elastic gap-eliminating mechanism; Described elastic gap-eliminating mechanism comprises the limited post 4 that is arranged on driving arm 1 top and bottom, described limited post 4 is fixed on the column 2, also has a lead 5 that is fixed on the column 2, described lead 5 passes driving arm 1, is provided with anti-backlash 13 between lead 5 and the driving arm 1.Described turning cylinder 3 is fixed on the column 2 by plate joint 6, and plate joint 6 is fixed on the column by hold-down screw 7, also is provided with a plurality of adjustment screw 8 on plate joint 6.
During work, driving mechanism 9 driven wheels 10 rotate, because tooth bar 12 engagements on gear 10 and the guide rail 11, so driving mechanism 9 moves forward or backward, drive driving arm 1, column 2 grades move forward or backward, because an end of driving arm 1 is fixed on the column 2 by turning cylinder 3, the other end limited location post 4 of driving arm 1, driving arm 1 in the vertical direction does not just have and departs from like this, in the horizontal direction, when running into tooth bar 12 projections or depression, owing to be provided with anti-backlash 13 between lead 5 and the driving arm 1, so both guaranteed that driving arm 1 can have displacement in the horizontal direction, has also guaranteed the engagement degree of gear 10 and tooth 12, avoid stuck, guaranteed cut quality and cutting accuracy.
