Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further detailed explanation:
Embodiment 1: as shown in Figure 1, a kind of improved bench drill, comprises drill bit 1, working plate 2, and described drill bit 1 vertically arranges, and described working plate 2 is horizontally disposed with, and is provided with angle board 3 on described working plate 2, is removably connected with supporting mass 4 on described angle board 3.
As shown in Figure 1, the angle of described angle board 3 is non-adjustable, described angle board comprises swash plate 31 and level board 32 two parts, the angle of described swash plate and level board is non-90 °, and the size of this angle is the arcwall face tangent line that makes bearing outer ring arcwall face and the drill bit contact point place angle perpendicular to drill bit 1.Described level board 32 is provided with hole one, and on described working plate 2, correspondence position is provided with hole two, one screw rods through described Kong Yiyu hole two, and screws by supporting nut, thereby angle board 3 is fixed on working plate 2.
As shown in Figure 4, on described supporting mass 4, be provided with and be with externally threaded screw rod 41, the face of cylinder of described supporting mass 4 is provided with groove 11, as shown in Figure 1, the hole 3 33 that described screw rod 41 passes on swash plate 31, and screw by supporting nut, thereby supporting mass 4 is fixed on angle board 3.
As shown in Figure 5, for the setting of angle board in prior art, now angle board 3 is horizontal by 90 ° of settings, because drill bit 1 is vertically to arrange, like this, when drill bit 1 touches the arcwall face of the bearing outer ring 12 on supporting mass 4, drill bit 1 is non-perpendicular state with the arcwall face tangent line 13 at this contact point place, pass through force analysis, the downward pressure F of drill bit can decomposite a power F1 to left down and the power F2 of bottom right at this contact point place, because supporting mass 4 and bearing outer ring 12 are not adjacent to completely, there is certain space centre, so this power F1 can make bearing outer ring move, as shown in Figure 6, bearing outer ring tilts, the hole inaccuracy that drill bit is up to like this, and easily there is waste product.
So the present invention allows angle board inclination certain angle, be plumbness thereby make drill bit 1 and the arcwall face tangent line 13 at contact point place, as shown in Figure 7, the downward pressure of drill bit can not make bearing outer ring move like this, and when drill bit punches, position is accurate, and percent defective is low.
From the above analysis, the angle of the required inclination of angle board and two factor analysis, the one, drill bit and arcwall face contact point, the position of namely required punching, another is exactly the radian of this some place bearing outer ring arcwall face.
When actual use, angle board is to have produced in advance, according to the arcwall face of bearing outer ring and punch position, choose the angle board of required angle, angle board 3 is fixed on working plate 2, then supporting mass 4 is fixed on angle board 3, the groove 11 on guarantee supporting mass 4 faces of cylinder is just to drill bit 1.Bearing outer ring is enclosed within on supporting mass, and drill bit is depressed, boring, and after can seeing the hole of depression, boring completes, and takes off bearing outer ring, then changes the bearing outer ring that there is no boring, continues boring.
Embodiment 2: because the angle board angle in embodiment 1 is non-adjustable, and in real work, when punching, the required angle of the bearing outer ring of different size is also not quite similar, so, the invention provides the adjustable structure of a kind of angle board angle.
The angle board of the fixed angle in Fig. 1 is taken off, change as the angle board of structure in Fig. 2, other parts are as embodiment 1.
As shown in Figures 2 and 3, described angle board 3 bottoms are provided with the axle 5 extending to both sides, on the working plate 2 of described angle board 3 both sides, be fixedly installed two positioning bodies 1, described axle 5 is through the Kong Si on positioning body one, and extend outside positioning body one, be rotatably connected on positioning body one, a described side is connected with angle adjusting mechanism through on the axle 5 of positioning body one.
Described angle adjusting mechanism comprises the gear 7 being fixedly connected on axle, and the tooth bar 8 engaging with gear, and described tooth bar 8 two ends are provided with screw rod 9 and push against, and described screw rod 9 coordinates and screws with the band internal thread hole of positioning body 2 10, thereby is fixed on positioning body 2 10.Described positioning body 2 10 is fixedly installed on working plate 2.
On described angle board, arrange porosely 3 33, the screw rod 41 of supporting mass 4 is through described hole 3 33, and screws by matching nut, thereby supporting mass 4 is fixed on angle board.Groove 11 on described supporting mass 4 faces of cylinder is just to drill bit.
When practical operation, bearing outer ring is enclosed within on supporting mass, the screw rod 9 at first turn tooth bar two ends, make it away from tooth bar 8, then mobile rack 8, thereby driven gear 7, and then the angle of adjustment angle board 3, according to bearing outer ring arcwall face radian and the punch position of required punching, adjust the angle of angle board 3, the arcwall face tangent line that makes bearing outer ring arcwall face on supporting mass and drill bit contact point place perpendicular to drill bit 1 after, turn screw rod 9 again, make it push against tooth bar 8, this angle is fixed, and just can start to have punched.
