In order to satisfy each axle thrust demand, above-mentioned linear electric motors basically all adopt cored linear electric motors as each axis drive motor, and cored linear electric motors in the course of the work; There are very big suction in the mover of linear electric motors and the stator of linear electric motors, and the suction direction is perpendicular to the linear electric motors installed surface, and driving power is big more; Suction is also just big more, and for general six drilling machines, the suction between its X, y-axis motor mover and the stator is generally more than 10KN; This suction is through motor fixing plate 15; Line slideway slide block 13 is reproduced in line slideway slide rail 12 and line slideway slide rail 16 with line slideway slide block 18, is out of shape under the powerful suction of motor owing to motor fixing plate 15 simultaneously, thereby makes line slideway slide rail 12 and line slideway slide rail 16 not only bear the normal pressure perpendicular to installation base surface; Bear the pulling force of side direction in the line slideway simultaneously; This normal pressure and pulling force influence the service life of guide rail on the one hand, influence the linearity of guide rail on the other hand, thereby influence the borehole accuracy of rig.Therefore it is poor that this linear guide rail structure has guiding accuracy, and service life is short, shortcomings such as manufacturing cost height.
The utility model content
For solving the problems of the technologies described above; The purpose of the utility model is to provide a kind of linear guide rail structure of PCB drilling machine; Adopt the air supporting pin to substitute a line slideway of traditional PCB drilling machine linear electric motors both sides; Not only can improve each kinematic accuracy of PCB drilling machine, in the service life that can improve line slideway simultaneously, reduce the manufacturing cost and use cost of equipment.
For achieving the above object; The technical scheme of the utility model is following: a kind of linear guide rail structure of PCB drilling machine; Comprise bearing, linear electric motors, line slideway and fixed head, be provided with said linear electric motors and line slideway between said bearing and the said fixed head, said line slideway is set in parallel in a side of said linear electric motors; The stator of said linear electric motors and the slide rail of said line slideway are arranged on the said bearing; The mover of said linear electric motors and the slide block of said line slideway are arranged on the said fixed head, also comprise the air supporting pin, and said air supporting pin is used to carry the normal pressure of said linear electric motors suction; Said air supporting pin is arranged on the said fixed head, and is arranged on the opposite side of said linear electric motors.
Preferably, said air supporting pin is provided with at least one.
Preferably, said air supporting pin is circular, square, hexagon or octagon.
Preferably, said slide block is provided with at least one.
Adopt the beneficial effect of present technique scheme to be: because the air supporting pin is arranged on the fixed head; And be arranged on a side of said linear electric motors; The air supporting pin only carries the normal pressure of linear electric motors suction in the course of the work; Other directions are freely-movable, so line slideway can not make the skew of its linearity owing to the suction of linear electric motors, thereby guarantee the borehole accuracy of drilling machine.Simultaneously the air supporting pin is compared with line slideway, is the slip of noncontact air pressure on the one hand between air supporting pin and the bearing, and the slide rail of comparing line slideway contacts slip with roller between the slide block of line slideway, and wear extent is little, long service life; Air supporting pin cost is low on the other hand, invalid oiling maintenance, so the cost of manufacture of machine and use cost are lower.
