Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.
A kind of calibration of the flexible sleeve section circularity based on pressure steering mechanism and clamping device, as shown in Figure 1, mainly comprise circumference pedestal 1 and support claw 2, the size of circumference susceptor diameter carries out designing according to the diameter of required clamping workpiece, meanwhile, the number of clamping brace pawl also changes according to the change of susceptor diameter.
As shown in Figure 2, Figure 3, Figure 4.Support claw 2 is numeral " 7 " type, it comprises cylinder section inner side baffle 7, pressing plate 8, double-slider pressure steering mechanism 9, cylinder push-rod 10 and cylinder 11, wherein cylinder section inner side baffle 7 is positioned at support claw 2 the first half left end, pressing plate 8 is positioned on the right side of cylinder section inner side baffle 7, and workpiece is placed between pressing plate 8 and inner side baffle 7.Cylinder 11 is positioned at the latter half of support claw 2, it is cylinder push-rod 10 on the upside of it, cylinder push-rod 10 upper end is connected with double-slider pressure steering mechanism 9 right-hand member, double-slider pressure steering mechanism 9 is the connecting rod of an inclined upward placement left, its upper left side is connected with on the right side of pressing plate 8, lower right links with push rod 10, and in the middle, link with support claw 2 with a connecting rod again, play the object of rock-steady structure, cylinder 11 can drive push rod 10 to move upward, power straight up converted to the horizontal thrust towards direction, the center of circle through double-slider pressure steering mechanism 9, finally act on pressing plate 8.Inner side baffle 7 maintains static, by pressing plate 8 by Work-sheet pressing on baffle plate 7, complete clamping.
Flat key 4 is connected by screw lower end on the left of support claw 2.Circumference pedestal 1 has the circumferentially radial T-shaped straight trough 3 of quantity same with support claw 2, flat key 4 can slide in T-shaped straight trough 3, thus drive whole support claw 2 circumferentially radial direction move, adjustment screw A5 is threaded with circumference pedestal 1, and be not connected with support claw 2, adjustment screw B6 is threaded with support claw 2, and is not connected with circumference pedestal 1.Like this, when needing the radius reducing support claw place circumference, tightening adjustment screw A (5) and loosening adjustment screw B6, support claw 2 will be drawn close toward direction, the center of circle; When needing the radius increasing support claw place circumference, loosening adjustment screw A5 and tightening adjustment screw B6, support claw will by top from the center of circle.For the cylinder section workpiece of different-diameter in certain limit, can finely tune among a small circle according to the diameter of this section workpiece, thus reach the object of circularity calibration.
For the cylinder section workpiece that length is long, in order to ensure that clamping is stable, described device can be intercepted two parts, intercepting part by two and installing face-to-face, and adjustment distance between the two, just can carry out clamping for the cylinder section workpiece of various length.
