Description of the invention: [Technical field to which the invention pertains] The present invention relates to an adjustable type of a ball screw.苒 / /, body and g, especially [previous technology], - structure. The ball screw is widely used in precision machinery because of its transmission precision, so that it is often set to - pressure, as shown in the first and second figures; == pre-stressed on the nut, adjustable The pre-press nut 1〇, π′, and two kinds of white, the adjustable screw type screw uses the screw 14 to adjust the two nuts 1〇,丨丨13, and the use of the thread 111 is the purpose of the whole collision force. _ can be pre-adjusted to achieve the complexity of the component, it must be in the main, but relatively also because the cap 12 is connected to the surface can be installed screws 14 1U, or in the size of the screw two Zhao, resulting in The manufacturing and assembly of two or two rotations will of course lead to an increase in production costs. -, in the car 乂 is a fee-based work, the year from ϊίΐϊ i to solve the above problems, the inventor of this case has been carefully thought out, the annual event of various ball screw and mesh, Soya Out of the species, the development of the test, several trials and trials [invention] Adjustable touch structure. Structure This is to provide an adjustable type of ball screw adjustable pre-size displacement piece 'with screw control to make it different 'Re-benefit--the pre-existing force of different sizes, because the pre-stress is 3 敕 because it is provided with the adjustable structure of the bead turn, the effect is effective. Another advantage of the present invention, which is easy to adjust, is to provide an adjustable pre-pressed knot of the ball screw 5^274820 which can be extended by the length or force of the protruding portion, so that the change is extremely simple and also The effect is 卞 卞 桃 桃 桃 桃 控制 控制 控制 控制 控制 控制 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃 桃- an end face ί each pre-compressed piece Don't make money in the two nuts of the ball screw, the pre-soils of the pre-squeezing slabs are in contact with each other, so that the force between the two nuts can be promoted by the twist. Aihua can produce different pre-stresses of different sizes. Point, committee, energy, one-step understanding of the structure, characteristics and other merits of the present invention on the New Zealand 丁 贯 合 合 详细 详细 详细 详细 详细 详细 详细 详细 详细 详细 详细 详细Wu Ming can have further experience and understanding. [Embodiment] The structure of the ball screw provided by the present invention is shown in Fig. 3 to Fig. 2, and the two caps of the six sides of the ball are provided. 3, between the three can be borrowed to produce a pre-pressure to adjust the ball screw, characterized in that the pre-pressure structure of the ... is generally composed of two pre-compression sheets 4, 5, and each pre-compression sheet 4, 5 The production has a bevel 41, 51 ', so that the pre-compression sheets 4, 5 are respectively sleeved between the 5 tf nuts 2, 3, and the slopes 4 of the pre-compression sheets 4, 5 are from the dragon Corresponding to the contact shape of each other, so that the relative displacement of the pre-compression sheets 4, 5 is performed, and the two nuts 2, 3 are forced. The pre-compression sheets 4, 5 are combined with the thickness to change, and the pre-pressures of different sizes can be produced. As for the action principle of the present invention capable of generating the pre-pressure, please refer to the fourth, fifth, and figure to clearly see that The end faces of the respective touch pieces 4, 5 are milled 2 the material faces 41, 51, assuming a lost angle between the inclined faces 4b 51 and the other corresponding faces 42, 52: 'Tian two pre-pressed sheets 4, 5 Starting from the superimposed state (as shown in Figure 5A), the relative position is flattened, and when the amount of movement is AL, the vertical direction will rise by M UH = μ x tana ) (as shown in the fifth β diagram), Since the difference between the two nuts 2, 3 is different, the height of the 12 1274820 i^7i7 is as shown in the fifth C, which is to explain the diameters, g, and F2 applied when we assemble. The force acting on the contact faces of the pre-compression sheets 4, 5 and the nuts 2, 3 (i.e., the pre-compression force is 1 " 1 ' and F3 represents the pre-dusting sheets 4, 5 with the inclined faces 41, 51 therebetween. As shown in FIG. 3, the pre-pressing structure of the present invention is mainly composed of two pre-pressing sheets 4, 5, a pad, a fixing key 7 and an adjusting screw 76, wherein one of the pre-pressing sheets 5 is opened.A plurality of fixed keys 7 are provided, and on the other pre-pressed sheets 4, beans are formed on the surface, and 11 can be implanted into the holes 411 by using the clamping pins so that the pre-pressing sheets 4 are combined with the K-cap 2 In addition, in the case, the coupling rib 521 is formed on the corresponding surface 52 of the pre-1 bean (10) inclined surface 51 in which the groove 53 is opened, and at the same time, the cap 3 is correspondingly formed with a length. The longer combination groove, such that f is fitted with the self-coupling groove 31. The pre-pressing piece 5 is moved by the radial thrust for 53 discs. The author is notable in the pre-pressing sheet 5 The change of the groove 2 ah can be resetted again - the gasket 6, of course, in order to obtain the control of the pre-pressure size, wherein the gasket 6 can be placed more than one piece, the pre-pressure generated is larger.
