Description of the invention: _ Technical field to which the invention pertains. The present invention relates to a positioning structure, and more particularly to a positioning structure for holding and positioning an indexing disk. [Prior Art] A slave-input-segment indexing plate often uses a tooth-shaped mechanism as a transmission component, such as a gear-to-gear or a smash-and-spin-off, which has the advantage of effectively reducing the power consumption of the motor to make the motor and the minute The dial achieves perfect matching and uses the appropriate gear ratio to achieve high torque and high rigidity. However, in reality, the toothed transmission has a backlash problem during reciprocation, and the tiny backlash can drive The rotating parts of the mechanism operate more smoothly, but the excessive backlash will result in the misalignment accuracy of the rotating part of the disc, the vibration during processing, and even the lowering of the life (4), and the backlash error often causes processing errors and errors. : and the phenomenon caused by long-term wear and tear; therefore, the industry is trying to solve the problem of the backlash caused by the toothed transmission by the difference of === dial. Eliminate tooth-shaped mechanism clamping and so on. Please refer to the figure, the second part of the various forms of the wall to add a catch for a known thin 劈 i i master gentleman 4 port diagram shown in the 'rotation piece U set positioning parts】, and section positioning ^ The wall 10 is applied to the thin wall 10 of the rotating member clamp member 1 - an external force is applied to the positioning member 1, and the alumina 10 is pressed against the rotating member 11. The thin wall 10 structure of L·, , , and is not easy to be controlled by the material, or the centering, and the error is not easy to control, and the user cannot control the thin wall]0= Π1336 1378842 clamping force 'to make the clip The force is evenly distributed on the thin wall 1〇, which tends to cause unevenness in the holding force on the rotating member 11, which causes the rotating member 11 to be misaligned after the clamping. —,, 匕 How to improve the above-mentioned problems of the conventional clamping and positioning structure is a topic that needs to be considered today. SUMMARY OF THE INVENTION In view of the above-discussed shortcomings of the prior art, it is a primary object of the present invention to provide a positionable structure that can be gripped and positioned. The spoon includes f and other purposes. The present invention provides a positioning structure, which is a body having a first inner ring surface and a first outer ring surface; and a second body body surrounding the corresponding position m - . % in vitro, with a second inner torus and clothing, J-shaped joints, corresponding to the first 盥 between the 盥 且 且 纟 纟 今 今 一 一 μ μ μ μ μ μ μ μ μ μ μ μ μ μ a body, such that the annular link, the first and the second ring body form a four-way transmission AM » concave & the groove has an opening, and the groove surface, the second: the vibration body An outer ring surface and a second inner ring of the second ring body of the second inner ring body are corresponding to the second inner ring and are disposed in the opening of the groove, and the densely formed -:: empty, the depth of the groove is In the structure between the groove and the sealing body, the first ring body, the second ring body and the annular ring; the second: the body member formed by the body, preferably the first ring body The transmission may be an elastic member, such as an elastic outer garment, the first inner ring face plate first-outer P shell, metal or non-metal composite material is wide, and the distance between the second inner production γΛ is the first wall. Wide, 兮The distance between the outer ring surface and the outer ring surface is that the width of the second wall is less than the width of the second wall width, and the first ring system can be a circular ring body, which can make the first The width of the wall is less than or equal to 5% of the diameter of the first inner annulus to have a thin wall structure. In the aspect in which the first ring body of the present invention is a circular ring body, since the second ring system surrounds the first ring body, the second ring body may also be a circular ring body. In the foregoing positioning structure, the first inner annular surface and the first outer annular surface may be a flat surface, and the second inner annular surface and the second outer annular surface may also be a flat surface, and The opening direction of the groove may be beveled or erected, but is not particularly limited. In the foregoing positioning structure, a sealing space is used for accommodating a fluid, and the second ring body has an opening communicating with the groove, and the opening is disposed in the axial direction. It is preferred to be away from the opening to inject fluid into the groove. Alternatively, the flow system may be an oil body such that the sealed space is a sealed oil chamber. The positioning structure is applicable to the rotary indexing plate, and the rotary indexing plate has a base and a sleeve disposed on the base, and the outer shape of the first ring body I corresponds to the outer shape of the kit; The groove may be located between the base and the sleeve, and the first ring body is correspondingly disposed at an edge of the sleeve, and the second ring body is correspondingly located at an edge of the base; preferably, the sleeve is rotatable The disk has a radial surface corresponding to the first inner annular surface of the first ring body, and the first inner annular surface is disposed on the radial surface of the rotating disk. It can be seen from the above that the positioning structure of the present invention forms a ring body with a different groove by the first ring body and the second ring body, and a sealing body is arranged on the groove to form a sealed space when given When the sealing space is pressurized enough to deform the first ring body to expand toward the center of the ring, the first ring body can be brought into contact with the member in the ring body to generate a frictional force. Moreover, by controlling the pressure of the sealing space, the average force on the first ring body can be uniformly generated to generate a uniform loss force, so that all parts of the object can be hooked off, and position deviation can be avoided to achieve the positioning effect. . According to the self-knowledge technology, the invention only needs to adjust the object plate when installing=the ring body is concentric, so as to eliminate the problem of uneven friction of the outer diameter due to material error or machining error during clamping, and effectively achieve positioning. And the second of the clamping: the external = 'the design of the fluid contained in the sealed space is also advantageous for control. And avoiding external force applied directly to the positioning structure to cause material deformation. [Embodiment] Embodiments of the present invention illustrate a specific embodiment of the present invention, so that the skilled person can easily understand The technical features of this creation and the achievement of the Shishi Mingyue = brother 2A to 2C diagram, providing a detailed structure of the positioning structure 2 (4) the joint structure 2 Sun includes: the first ring body 21, the second ring body 22, the %-shaped joint piece 23 and the sealing body 24.
