Detailed description of the invention
Illustrate that the invention will be further described with detailed description of the invention below in conjunction with accompanying drawing:
A kind of centrifugal clamp system for spinning machine as shown in Figures 1 to 4, comprise the flange seat 1 be connected with whirler main shaft, active pull rod 2 is movably set with in described flange seat 1, the collet mechanism 3 of clamping machining workpiece when being connected with for rotating in described active pull rod 2, described flange seat 1 is hinged with flange seat 1 rotate the multiple of Shi Nengshi collet mechanism 3 movement and get rid of block 4, the described block 4 that gets rid of is distributed on described flange seat 1 outside, the described block 4 that gets rid of is movably connected on described active pull rod 2 by connecting rod 5, back-moving spring 6 is provided with between described flange seat 1 and active pull rod 2.The collet putting into collet mechanism 3 from workpiece in the present invention rotates to collet and has a very short process completely clamping work pieces, for preventing workpiece movable in the process, the present invention placed a back-moving spring 6 between active pull rod 2 and flange seat 1, under the effect of back-moving spring 6, active pull rod 2 can move a distance after main shaft rotates forward direction, and drive collet to move backward, make workpiece be in the state of pre-clamping and locate.
Be connected with balancing weight 7 described getting rid of on block 4 in the present invention, described getting rid of in the middle part of block 4 is hinged on flange seat 1, described in get rid of block 4 one end and connecting rod 5 is hinged, described balancing weight 7 be arranged on get rid of block 4 the other end on.Centrifugal force that block 4 produces converts active pull rod 2 to axial tension by connecting rod 5 is got rid of as the spindle turns in the present invention, this axial tension of amplification due to connecting rod 5 is 5 ~ 10 times of centrifugal force, and axial tension is finally converted to the clamping force of collet to workpiece.Centrifugal force size gets rid of the weight adjustment of balancing weight 7 on block 4 by adjustment, thus realizes the adjustment of mechanism to clamping force.
Active pull rod 2 one end described in the present invention is movably arranged in flange seat 1, and active pull rod 2 other end is evenly equipped with multiple engaging lug 8, and one end of described connecting rod 5 is hinged on described engaging lug 8.
Collet mechanism 3 described in the present invention includes collet pull bar 31, described collet pull bar 31 one end is provided with collet 32, outside described collet 32, be arranged with collet lock sleeve 33, be threaded locking nut 34 at described collet pull bar 31 other end.
On described collet pull bar 31, limited step 35 is provided with in the present invention, described top, active pull rod 2 one end is pressed on described limited step 35, described active pull rod 2 one end is provided with external screw thread, and described active pull rod 2 is connected on collet pull bar 31 by locking nut 34.
The first implementation method of the present invention, the described block 4 that gets rid of is four pieces, and described four pieces are got rid of block 4 and are evenly distributed on described flange seat 1.
The second implementation method of the present invention, the described block 4 that gets rid of is three pieces, and described three pieces are got rid of block 4 and are evenly distributed on described flange seat 1.
The third implementation method of the present invention, the described block 4 that gets rid of is two pieces, and described two pieces are got rid of block 4 and are evenly distributed on described flange seat 1.
The present invention is used in the centrifugal clamp system of spinning machine, flange seat 1 is connected on the main shaft of spinning machine, getting rid of block 4 is connected on flange seat 1, and be connected with active pull rod 2 by connecting rod 5, as the spindle turns, flange seat 1 rotates together with main shaft and drives the block 4 that gets rid of being provided with balancing weight 7 to rotate together, in rotary course, get rid of block 4 due to the effect of centrifugal force can outwards open, by connecting rod 5, the opening movement getting rid of block 4 will drive active pull rod 2 to move backward and promote locking nut 34 and move backward, the collet pull bar 31 be threaded with locking nut 34 and then moves backward thus drives collet 32 to move backward, complete the clamping of the workpiece that will process under rotation status under the interaction of collet lock sleeve 33 and collet 32.
After process finishing, effect workpiece due to back-moving spring 6 during spinning machine main shaft non rotating still can be in pre-clamped condition, in use has a special cylinder to promote active pull rod 2 and offsets the elastic force playing back-moving spring 6 and move forward thus drive collet 32 reach to unclamp workpiece.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
