Technology solution of the present utility model is as follows:

The smart drilling machine that bores of Its Counter-measures on Motorcycle Damping Cylinder endoporus comprises smart drill bit, and the driven by motor driving gear rotates, and driving gear is meshed with idler gear, and idler gear is meshed with driven gear, and driven gear is fixed on the main shaft;

Main shaft is fixed on the inner ring of bearing, the outer ring of bearing is fixed on the main spindle box, the main shaft case lid is pressing sealing ring to be fixed on the opening part of main spindle box by screw, be with rubber washer on the main shaft, smart drill bit is fixed on the main shaft, oil inlet pipe connects the nozzle opening on the main shaft, and the middle part of main shaft forms out oil hole;

Main spindle box is fixed on the slide unit, and the hydraulic oil cylinder driving slide unit is along the guide rail linear slide; The rear portion of main shaft connects swivel joint, has connected flowline on the swivel joint, and workpiece is fixed on the workpiece fixing seat.

Be fixed with the outer ring spacer on the outer ring of described two bearings, be fixed with the inner ring spacer on the inner ring of two bearings, form through hole on the spacer of outer ring and oil inlet pipe connects.

The beneficial effects of the utility model are: 1, it is simple in structure, and equipment cost is low, is particularly suitable for smart the boring of Its Counter-measures on Motorcycle Damping Cylinder endoporus and uses.

2, hydraulic oil has lubricated bearing before in spraying into the workpiece endoporus, has prolonged the service life of bearing.

Description of drawings:

Fig. 1 is a structural representation of the present utility model

Among the figure: 1, workpiece fixing seat; 2, main shaft; 3, smart drill bit; 4, rubber washer; 5, main shaft case lid; 6, sealing ring; 7, oil inlet pipe; 8, bearing; 9, inner ring spacer; 10, outer ring spacer; 11, main spindle box; 12, slide unit; 13, guide rail; 14, swivel joint; 15, driving gear; 16, idler gear; 17, motor; 18, driven gear; 19, flowline; 21, go out oil hole; 22, nozzle opening; 101, through hole.

The specific embodiment:

Embodiment: see shown in Figure 1ly, the smart drilling machine that bores of Its Counter-measures on Motorcycle Damping Cylinder endoporus comprises smart drill bit 3, motor 17 drives driving gear 15 and rotates, driving gear 15 is meshed with idler gear 16, and idler gear 16 is meshed with driven gear 18, and driven gear 18 is fixed on the main shaft 2;
