The specific embodiment
Extremely shown in Figure 6 such as Fig. 1, the clamp mechanism of radial drilling machine of the present invention, comprise column and rocking arm, column comprises inner prop 1 and the column jacket 2 that is socketed on outside the inner prop 1, the lower end of column jacket 2 and inner prop 1 is provided with the conical surface 3 that mutually agrees with, be socketed with Rocker arm 5 by macropore 4 on the column jacket 2, this clamp mechanism comprises rocking arm clamp mechanism and vertical pole fastening mechanism; the rocking arm clamp mechanism places in the Rocker arm 5; the rocking arm clamp mechanism comprises the diamond block clamp mechanism of leverage and support lever mechanism; leverage comprises lever 6 and places the clamping device at lever 6 two ends; clamping device comprises clamping screw 7 and fishbolt 8; lever 6 is provided with the rhombus clamp mechanism; the rhombus clamp mechanism comprises screw rod 9; clamp mechanism that places the worm gear 10 on the screw rod 9 and place worm gear 10 upper ends; worm gear 10 1 sides are provided with worm screw 11; clamp mechanism comprises the pressure block 12 that places on the screw rod 9; place the diamond block 13 of pressure block 12 both sides; the diamond block 13 of a side is provided with the jacking block 14 that places on the lever 6; diamond block 13 of opposite side is provided with briquetting 15, and the upper end of screw rod 9 is provided with switch A16 and switch B17;
As shown in Figure 1 to Figure 3, in the rocking arm clamp mechanism, motor 34 forces screw rod 9 to move through worm screw 11 so that worm gear 10 rotates, promote diamond block 13 to stand up position through pressure block 12, promote levers 6 and so that clamping screw 7 tension macropores 4 are held column jacket 2 tightly, clamped position has switch A16 control through jacking block 14, motor 34 stops, do not lose efficacy because diamond block 13 after the double self locking effect assurance clamping of worm gear 10 and screw rod 9 can not tilt to cause to clamp, the height of briquetting 15 is A at this moment; When unclamping, motor 34 counter-rotatings are moved to diamond block 13 and are loosened lever 6 by screw rod 9, macropore 4 Self-bouncings and free clamping, the time length of motor 34 counter-rotatings has determined the angle that screw rod 9 displacements and diamond block 13 fell, these actions are controlled with switch B17, at this moment, the height of briquetting 15 is A ', the height that produces because A '＜A reduce and so that lever 6 loosen, 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.
Extremely shown in Figure 6 such as Fig. 4, the operating principle of vertical pole fastening mechanism is identical with the rocking arm clamp mechanism, but power resources are different, in vertical pole fastening mechanism, lever A20 fulcrum be the capital 19 that is fixed on the inner prop 1, lever A20 is subjected to diamond block A31 effect to produce swing, so that column jacket 2 moves axially up and down with respect to inner prop 1, when depressing column jacket 2 when lifting on the 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, when diamond block A31 tilts, lever A20 loosens, column jacket 2 promotes under the effect of plectane spring 21 and lifts, 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 the rocking arm clamp mechanism and switch B, the clamping force size can be by adjusting the nut 23 on the capital 19, pass through screw 24 fastening lockings after suitable, the elastic force that the adjustment screw 22 that distributes on the plectane spring 21 is used for adjusting plectane spring 21 makes it be enough to promote 2 contacts of the column jacket 2 disengaging conical surfaces, this cover mechanism can guarantee to apply the horizontal force of 1200N and unlikely movement at the Rocker arm 5 end after column clamps, to guarantee the machining normal operation, after unclamping, the power that applies less than 30N at the Rocker arm 5 end just can promote Rocker arm 5 easily, column jacket 2 unclamps, the upper and lower displacement that clamps is 0.15-0.30mm normally, and is substantially noiseless during action.
Diamond block clamp mechanism and diamond block clamp mechanism A make with paraffin mould precision casting technology can reduce cost, worm gear 10 and worm gear A25 are not high stressed little because of rotating speed, make with spheroidal graphite cast-iron, therefore with low cost and reliable in structure, makes easy to maintenance and power consumption less the life-span long.
