Outside mounting hole.
Preferentially elastic tape is provided with the outer wall of the roller.
Two elastic mechanisms are provided with Fig. 1 on every gripper edge.
During press-fiting, pneumatic cylinder promotes handgrip finger to catch axle, axle pressure to act on roller, axle and two handgrips
During finger relative motion, now, axial compressive force suffered by axle becomes big, and roller is rolled and reduced between axial cylindrical surface and hand grip
Friction, reduces the unnecessary damage in axle surface；When axis hole is not to the heart, because axle bottom diameter is less than axle sleeve aperture（Axle
In design, there is tapered guide area lower end）, now, axle at first with the side contacts of inner surface one of axle sleeve hole, axle stress forces rubber
Circle compression, is that hole heart direction is moved to opposite side, final to ensure that axis hole is concentric.
As shown in Fig. 2 another elastic mechanism includes support frame, roller shaft, roller and support spring；Support frame is upper end
Opening, the hollow cylinder of lower end closed；Roller shaft pass through the roller, two ends respectively with the both sides fixing phase of support frame inwall
Even；Roller can freely be rotated around roller shaft, and a part for roller is prominent outside support frame as described above；Support spring one end and bullet
The bottom of property mechanism mounting hole offsets, the bottom of the other end and support frame as described above offsets, in compressive state；Elastic mechanism is installed
Being provided with least one along the direction of extension of support spring on the inwall in hole is used to limit the limit sliding chutes of support frame sliding distance, institute
The cylinder for stating the sliding block and support frame as described above being provided with sliding block, and limit sliding chutes in limit sliding chutes is fixedly linked；One of roller
Divide prominent outside the mounting hole of elastic mechanism.
Compared with the first elastic mechanism, the elastic mechanism replaces rubber ring with support spring, and anti-wear performance is more preferable, together
When, program limited location chute can precise control scroll wheel positions and clamping force.During press-fiting, pneumatic cylinder promotes handgrip hand
Finger catches axle, axle pressure to act on roller, and support spring is pressurized and shrinks, and roller can be made to be unlikely in whole retraction type holes, axle
During with two handgrip finger relative motions, now, axial compressive force suffered by axle becomes big, and roller is rolled and reduces axial cylindrical surface with machinery
Friction between hand handgrip, reduces the unnecessary damage in axle surface；When axis hole is not to the heart, because axle bottom diameter is less than axle
Set aperture（Axle has tapered guide area in lower end in design）, now, axle at first with the side contacts of inner surface one of axle sleeve hole, axle stress
Force support spring to be compressed, be that hole heart direction is moved to opposite side, it is final to ensure that axis hole is concentric.
