Detailed description of the invention
As shown in Figures 1 to 6, the clamp mechanism of radial drilling machine of the present invention, comprises column and rocking arm, in column comprises
Post 1 and be socketed on the column jacket 2 outside inner prop 1, the lower end of column jacket 2 and inner prop 1 is provided with the conical surface 3 mutually agreeing with, on column jacket 2, be socketed with Rocker arm 5 by macropore 4, this clamp mechanism comprises rocking arm clamp mechanism and vertical pole fastening mechanism, rocking arm clamp mechanism is placed in Rocker arm 5, rocking arm clamp mechanism comprises the diamond block clamp mechanism of leverage and support lever mechanism, leverage comprises lever 6 and is placed in the clamping device at lever 6 two ends, clamping device comprises clamping screw 7 and fishbolt 8, lever 6 is provided with diamond block clamp mechanism, diamond block clamp mechanism comprises screw rod 9, be placed in the worm gear 10 on screw rod 9 and be placed in the clamp mechanism of worm gear 10 upper ends, worm gear 10 1 sides are provided with worm screw 11, clamp mechanism comprises the pressure block 12 being placed on screw rod 9, be placed in the diamond block 13 of pressure block 12 both sides, the diamond block 13 of one side is provided with the jacking block 14 being placed on lever 6, the diamond block 13 of opposite side is provided with briquetting 15, the upper end of screw rod 9 is provided with switch A16 and switch B17,
Column jacket 2 upper ends are provided with cavity 18, the upper end of inner prop 1 is provided with the capital 19 extending in cavity 18, in cavity 18, be provided with vertical pole fastening mechanism, vertical pole fastening mechanism comprises lever A20, rhombus clamp mechanism A, lever A20 is placed in the both sides of capital 19, the lower end of lever A20 is provided with plectane spring 21, on plectane spring 21, circle distribution has adjustment screw 22, the upper end of capital 19 is provided with adjusting device, adjusting device comprises the nut 23 and the screw 24 that are placed on capital 19, the rear side of lever A20 is provided with worm screw A25 and switch D26, rhombus clamp mechanism A comprises switch C27, clamp mechanism A and screw rod A28, on screw rod A28, be socketed with worm gear A29, one end of screw rod A28 is provided with clamp mechanism A, one end of clamp mechanism A is provided with switch C27, clamp mechanism A comprises pressure block A30 and is placed in the diamond block A31 of pressure block A30 both sides, the diamond block A31 of one side is provided with jacking block A32, the diamond block A31 of opposite side is provided with briquetting A33.
As shown in Figure 1 to Figure 3, in rocking arm clamp mechanism, motor 34 makes worm gear 10 rotations force screw rod 9 to move through worm screw 11, promote diamond block 13 to stand up position through pressure block 12, promote lever 6 and make clamping screw 7 strain macropore 4 to hold column jacket 2 tightly through jacking block 14, clamped position has switch A16 to control, and motor 34 stops, can not tilt to cause to clamp inefficacy because the double self locking effect of worm gear 10 and screw rod 9 ensures to clamp rear diamond block 13, now the height of briquetting 15 be A; In the time unclamping, motor 34 reverses and is moved to diamond block 13 and loosened lever 6 by screw rod 9, macropore 4 Self-bouncings and free clamping, the time length that motor 34 reverses has determined the angle that screw rod 9 displacements and diamond block 13 fell, these actions are controlled with switch B17, now, the height of briquetting 15 is A ', because the height that A ' < A produces reduces, lever 6 is loosened, therefore this mechanism has very strong power-saving function, and the thrust that pressure block 12 is subject to can be amplified 14.28 times through diamond block 12 and be reached briquetting 15.
Worm gear 10, screw rod 9, lever 6 and diamond block 13 in Zhe Tao mechanism are effort-saving mechanism, motor 34 that need only 0.12KW just can produce the clamping force of 15000N, stressed when clamping is increasing process from small to large, minimum so consume energy, while unclamping, because clamping element all must get loose fast in wedging state, with respect to clamping process, power consumption is larger, so need to join the motor 34 of 0.37KW, therefore power consumption is few, substantially can under silent state, work, and under the very little state of frictional force, realizes long-lived effect.
As shown in Figures 4 to 6, the operating principle of vertical pole fastening mechanism is identical with rocking arm clamp mechanism, but power resources
Different, in vertical pole fastening mechanism, lever A20 fulcrum be the capital 19 being fixed on inner prop 1, lever A20 is subject to diamond block A31 effect to produce swing, column jacket 2 is moved axially up and down with respect to inner prop 1, while depressing column jacket 2 when lifting on lever A20 right-hand member, the conical surface 3 of the conical surface 3 wedging inner props 1 of column jacket 2 lower ends and clamp inner prop 1 and column jacket 2, in the time that diamond block A31 tilts, lever A20 loosens, column jacket 2 promotes and lifts under the effect of plectane spring 21, the conical surface 3 is freed contact and is unclamped inner prop 1 and column jacket 2, the effect of switch C and switch D is with switch A in rocking arm clamp mechanism and switch B, clamping force size can be by adjusting the nut 23 on capital 19, after suitable, pass through the fastening locking of screw 24, the adjustment screw 22 distributing on plectane spring 21 departs from the conical surface 2 and contacts for regulating the elastic force of plectane spring 21 to make it be enough to promote column jacket 2, Zhe Tao mechanism can ensure to apply the horizontal force of 1200N and unlikely movement at Rocker arm 5 end after column clamps, normally work to guarantee machining, after unclamping, apply at Rocker arm 5 end the power that is less than 30N and just can promote easily Rocker arm 5, column jacket 2 unclamps, the normally 0.15-0.30mm of upper and lower displacement clamping, substantially noiseless when action.
Diamond block clamp mechanism and rhombus clamp mechanism A make and can reduce costs with paraffin mould precision casting technology, worm gear 10 and worm gear A25 because of rotating speed not high stressed little, make with spheroidal graphite cast-iron, therefore with low cost and reliable in structure, manufactures easy to maintenance and few life-span of power consumption is long.
