The specific embodiment
Following the present invention will combine the embodiment in the accompanying drawing to further describe:
The present invention mainly comprises shell body 1, tapered sleeve 3, axle sleeve 4, ring flange 5, belt wheel 6, main shaft 7, casing 8, dials arm 9, flange 11, hollow pipe 12, lining 13, promotes cover 14, shift fork 16, cylinder 17 and bearing 19.
As depicted in figs. 1 and 2, connect main shaft 7 on the said casing 8, connect belt wheel 6 on the main shaft 7; Said belt wheel 6 left side mounting flanges 5, ring flange 5 left side connecting bushings 4; Said main shaft 7 left ends and axle sleeve 4 inner surfaces are through being threaded; The said main shaft 7 inner hollow pipes 12 of installing, hollow pipe 12 can move axially in main shaft 7; Said axle sleeve 4 is installed in the keyway of tapered sleeve 3 through axle key; Said shell body 1 connects tapered sleeve 3 through screw 2.Said tapered sleeve 3 can move axially in the keyway on axle sleeve with shell body 1.Said hollow pipe 12 front ends connect promotion cover 14.Said axle sleeve 4 outer end adpting flanges 11, flange 11 inner mounting bush 13.Be provided with four spring eyes 20 in said tapered sleeve 3 and the shell body 1, a compression spring 15 is installed in each spring eye 20.The front end of said compression spring 15 closely contacts with spring eye 20 interior shell body 1 inboards, and the rear end of compression spring 15 closely contacts with the end face of ring flange 5.
Said axle sleeve 4 is provided with four mounting grooves 21, installs one through pin 10 in said each mounting groove 21 and dials arm 9, dials arm 9 and can rotate around pin 10.The front end of said tapered sleeve 3 is provided with taper surface, and long contact one end that taper surface can promote to dial arm 9 is around pin 10 rotations.
Like Fig. 3 and shown in Figure 4, said casing 8 lower end erection supports 19 connect shift fork 16 on the bearing 19; Said shift fork 16 lower ends connect cylinder 17, and shift fork 16 upper ends are positioned at the shell body both sides.Both sides, said shift fork 16 upper end connect a briquetting 18 respectively.Said briquetting 18 is close to shell body 1.
Operation principle of the present invention is: at work, when the needs clamping work pieces, cylinder 17 is in contraction state, and shift fork 16 does not contact with shell body 1.Elastic return force urges tapered sleeve 3 and shell body 1 that compression spring 15 does not receive external force to pass through self slide left together.This moment tapered sleeve 3 taper surface promote to dial arm 9 long contact along pin 10 rotations, make its short contact promote cover 14 and drive hollow pipe 12 move to the right, thus the interior chuck of clamping front end flange 11.When main shaft 7 rotations were got up, four groups of arms 9 rotated together with shell body 1 and main shaft 7, and the long contact of dialling arm 9 can outwards move because of action of centrifugal force, made the promotion of pushing down tightly of short contact overlap 14, guaranteed that workpiece is clamped.
When need unclamped workpiece, main shaft 7 stopped operating, and cylinder 17 promotes shift fork 16 lower ends; The upper end that drives shift fork 16 moves right, and pushes down shell body 1 through briquetting 18 and moves right, and compression spring 15 is compressed; The long contact of dialling arm 9 loses the motive force of tapered sleeve 3 taper surfaces; Its short contact is unable to withstand little cover 14, and the power of main shaft 7 front end chuck sides is moved hollow pipe 12 backward, thereby unclamps workpiece.
