Description of the invention: [Technical field to which the invention pertains] The present invention relates to a feed mechanism of a machine tool, and more particularly to a rotary fine adjustment mechanism of a dual-drive simultaneous positioning platform. [Prior Art] The conventional dual-drive co-location platform A (such as the gantry structure) is composed of a cross-member A1 fixed to a support A2 at both ends thereof as shown in Fig. 1, and is respectively linked by the linear drive system B. The two-pillar A2 is used for displacement, so the linear transmission system B connected to the two-pillar A2 must be operated synchronously to keep the overall mechanism moving smoothly, but if there is an error in the synchronous control, the beam A1 and the beam are caused. The displacement error of the two-pillar A2 is fixedly connected between the beam A1 and the two-pillar A2, so that the structure of the double-drive co-location platform A is distorted and may even cause damage to the linear transmission system B. The longitudinal beam and the lateral direction of the beam A1 and the pillars A2 can be adjusted, and the relative position of the beam A1 and the pillars A2 can be compensated for positional deformation, thereby preventing distortion of the double-drive simultaneous positioning platform A. In addition, there is also a design for increasing the relative rotation between the beam A1 and the pillars A2, thereby improving the position compensation effect of the beam A1 and the pillars A2; and the beam A1 and the pillars A 2 relative rotation design, 5 of which, as shown in Fig. 2, is in the "2"-motor A3, the motor A3 is connected to the beam A1, so that the linear drive system connected to the strut (four) B generates an error in the control of the synchronous actuation, and when the displacement error between the horizontal axis A1 and the two-pillar A2 is generated, the two-pole A3 controls the rotation of the two-pillar A2 relative to the horizontal axis M, and can be as described in the fourth (fourth) The beam A1 and the pillars A2 are positionally compensated, but this design must be doubled, and the two motors A3' are installed in the dynamic positioning platform a to increase production and manufacturing costs, and the complexity of the mechanism is added. For this reason, a design as shown in the fourth embodiment has been developed, which is to change the respective A2 of the double-drive platform to the platform A to the support piece A4 of (4), so that when the support pieces A4 are connected The linear transmission system β generates an error in the control of the synchronous actuation, causing a displacement error of the beam αι and the two supporting pieces A4. Since the two supporting pieces μ are thin and structurally, they can be twisted to absorb the displacement error ( As shown by the dotted line in the figure, although no additional motor is required, The disadvantage of the distortion of the positioning platform A is unresolved, which may cause the two selected pieces A4 to be permanently deformed' and the A _ property of the double-moving positioning platform is also weak; Disadvantages of Twisting Deformation [The conventional design increases the shortcomings of the motor A3 to make money and material complexity, and the disadvantage of using the support piece A4 to reduce the structural strength and easily deform." The creator developed a dual-drive simultaneous positioning platform. The invention mainly provides a rotary fine adjustment mechanism of a double-drive synchronous positioning platform, which uses a positioning column to pivotally connect a beam and a pillar of the dual-drive simultaneous positioning platform, and An elastic member is disposed between the support members to positionally compensate the pivotal cross member and the support post relative to the pivoting column, and the elastic member increases the rigidity between the cross member and the support post. In order to achieve the foregoing objective, the rotary fine adjustment mechanism is disposed between the beam and the pillar of the dual-drive co-moving positioning platform, and includes a positioning post and at least two projectiles, and the clamping post pivotally connects the beam and the pillar. The elastic members respectively lie between the beam and the pillar, and the elastic members respectively abut the beam by the two sides of the beam; when the beam of the double-drive simultaneous positioning platform and the two pillars have a displacement difference 4 'the; ^ between the beam and the struts, the positioning column can be rotated relative to the axis to provide position compensation between the beam and the struts, and the beam will compress when it is dragged relative to the struts - The elastic members on the side, so that the 11 pieces can provide resistance against the pivoting of the pivot 1330567 between the posts, thereby increasing the rigidity between the beam and the legs. [Embodiment] The rotation fine adjustment mechanism of the dual-drive co-positioning platform of the present invention is implemented between the beam A1 and the pillar A2 of the dual-drive co-location platform A, as shown in Figs. 5 and 6, and includes: The column 10 has one end penetrating the beam A1 and inserted into the pillar A2, so that the positioning post 10 is pivotally connected to the beam A1 and the pillar A2, and the transverse direction A1 and the sill pillar A 2 can be relatively rotated. The column 20 is connected to the beam A1 and the column A2 by the radial direction of the positioning column 10, and the two locking posts 20 are connected to the beam A1 and the column A2 by one side of the beam A1, and the other two columns 20 are The other side of the beam A1 is connected to the beam A1 and the column A2. In this embodiment, each of the locking posts 20 has a threaded end, and the locking posts 20 penetrate the pillar A2 at this end and lock the beam A1. The two elastic members 30 are respectively disposed on the lock cylinders 20, and the elastic members 30 disposed on the lock cylinders 20 are located at the lock cylinders 20, respectively. Between the pillar A2, another elastic member 30 is located between the beam A1 and the pillar A2, wherein the four elastic members are 30 positions. The cross A1 - side, and the other four resilient member 30 is located on the other side of the beam A1, illustrated in the drawings briefly described [1330567] FIG driving the first embodiment of this known dual-drive platform with the perspective view of the positioning movement.
