Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As shown in Fig. 3,4,5, the stationary fixture of this U-shaped annular element comprises the base 2 of a circle, and base 2 is provided with eight radially-arranged T-shaped grooves 3, and the interval angle between adjacent two T-shaped grooves 3 is 45 °.In each T-shaped groove 3, be provided with two T-shaped slide blocks 8, T-shaped slide block 8 can slide back and forth in T-shaped groove 3.T-shaped slide block 8 is provided with locating piece 4, and T-shaped slide block 8 is connected by lock screw 5 with locating piece 4, and rotational lock screw 5 makes T-shaped slide block 8 compress the inwall of T-shaped groove 3, T-shaped slide block 8 can be fixed in T-shaped groove 3.
As shown in Figure 6,7, the locating piece 4 on two T-shaped slide blocks 8 in same T-shaped groove is oppositely arranged, and on the relative face of two locating pieces 4, is respectively equipped with fine setting piece 6, and fine setting piece 6 is connected with locating piece 4 by fine adjustment screw 7.Fine setting piece 6, locating piece 4 are inclined-plane with the face that fine adjustment screw 7 is connected, the inclined-plane of locating piece 4 is provided with screw thread, rotatable being stuck in fine setting piece 6 of one side of fine adjustment screw 7, the inclined-plane threaded engagement of the opposite side of fine adjustment screw 7 and locating piece 4, rotary fine adjustment screw 7 can drive fine setting piece 6 to move up and down, and can realize moving horizontally of fine setting piece 6 simultaneously.Fine setting piece 6 is vertical plane away from the face of locating piece 4 one sides, relatively finely tunes the distance between piece by adjustable two of rotary fine adjustment screw 7.The face that fine setting piece 6, locating piece 4 are connected with fine adjustment screw 7 is inclined-plane, so not only be conducive to the adjusting of fine adjustment screw 7, and can be at the height that regulates two relatively to regulate fine setting piece 6 between fine setting piece 6 in distance, make to finely tune piece 6 and can better clamp U-shaped annular element 1, thereby can play better fixation to U-shaped annular element 1, to prevent that U-shaped annular element 1 from producing vibration in process.
The stationary fixture of this U-shaped annular element, in when assembling, is first put into successively two T-shaped slide blocks 8 in every T-shaped groove 3, the narrow limit of T-shaped slide block 8 upward, broadside down.And then locating piece 4 is fixed on T-shaped slide block 8 by lock screw 5, the narrow limit of locating piece 4 down, broadside upward, and make the inclined-plane of two locating pieces 4 relative.Rotational lock screw 5 can make the broadside of T-shaped slide block 8 be pressed on the inwall of T-shaped groove 3, and T-shaped like this slide block 8 can be fixed in T-shaped groove 3.Finally connect fine setting piece 6 and locating piece 4 by fine adjustment screw 7, and make the vertical plane of two fine setting pieces 6 on same T-shaped groove relative.
The stationary fixture of this U-shaped annular element in use, first according to the preliminary position that will fix the diameter of U-shaped annular element 1 and thickness and determine each T-shaped slide block, then U-shaped annular element is placed on base 2, and by regulating T-shaped slide block 8, fine setting piece 6 that U-shaped annular element 1 is clamped.Then base 2 is fixed on a rotating shaft, drive base 2 rotations also to observe the concentricity of U-shaped annular element 1 and base 2 by dial gauge by rotating shaft simultaneously, ensure that according to the position of the corresponding T-shaped slide block 8 of deviation adjusting, fine setting piece 6 U-shaped annular element 1 is concentric with base 2 again, so just can prevent that U-shaped annular element from producing vibrations in process engineering.
Using the U-shaped annular element of this setting tool is to clamp sidewall by two relative fine setting pieces on each T-shaped groove to be fixed, and there will not be the problem of flattening deformation, can effectively ensure the crudy of U-shaped annular element.This stationary fixture can be determined according to the diameter of U-shaped annular element and wall thickness the position of T-shaped slide block in T-shaped groove simultaneously, and versatility is better, can use the U-shaped annular element of multiple different-diameter and thickness.
