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] In the past, the dual-drive co-location platform A (such as the gantry structure) is composed of a beam A1 fixed to the two ends of the beam A1, and is respectively fastened by the linear drive system B. The two-pillar A2 is actuated by displacement, so the linear drive system B connected to the two-pillar A2 must be operated synchronously to maintain the smooth operation of the overall mechanism, 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 A is due to the fixed connection between the beam A1 and the two-pillar A2, so that the structure of the dual-drive co-positioning platform A is distorted and may even cause a flaw in the linear transmission system B. The shell injury is designed to allow longitudinal and lateral adjustment of the sheet beam A1 and the pillars μ to positionally compensate the relative position of the beam A1 and the pillars A2, thereby preventing the double-drive simultaneous positioning. The distortion of the platform A is additionally increased to allow the beam A1 to rotate relative to the pillars A2, and the compensation effect of the beam A1 and the respective A2 can be increased; the beam A1 and the pillars A2 are For the design of the rotation, wherein 5 201008699 - as shown in Figure 2, is provided in the respective feA2 - the motor A3 is connected to the beam , so that the linear drive system of the struts is connected When there is an error in the control of the synchronous operation, when the beam Α1 and the two-pillar Α2 generate a displacement error, the two-pillar Α2 is controlled by the two-horse=A3 to rotate relative to the beam A1, and as shown in FIG. 3, the The beam A1 and the pillars A2 are positionally compensated, but this design must additionally install the _ A A A3 in the double-drive co-location platform A, which increases the production and manufacturing costs, and adds a complex = degree; for this reason, a design as shown in Fig. 4 has been developed on the market, in which the pillars A2 of the double-drive simultaneous positioning platform A are changed to the thinner support sheets A4, so that the support sheets are The linear drive system B connected to the column A4 generates an error in the control of the synchronous operation, causing a displacement error between the beam A1 and the two branches A4. Since the two pieces of the floor A4 are thinner, they can be distorted. And absorb the displacement error (shown by the dotted line in the figure), although An additional motor is required, but the disadvantage of the punctual platform A twisting the two shoulders is unresolved, which may cause the second reading A4 to produce permanent worries, and the rigidity of the dual-drive co-positioning platform A is also weak; Resolving the shortcomings of the twisting deformation of the dual-drive co-location platform A, the conventional design increases the cost of the motor A3 and the design is complicated, and the use of the support sheet causes the structural strength to decrease and the easy deformation of the long-term 6 201008699 Disadvantages' This creator developed a rotary fine-tuning mechanism for a two-drive simultaneous positioning platform. SUMMARY OF THE INVENTION The main object of the present invention is to provide a rotary fine adjustment mechanism for a dual-drive simultaneous positioning platform, which uses a positioning post to connect the beam and the pillar of the dual-drive simultaneous positioning platform, and is disposed between the beam and the pillar. The elastic piece 'allows the beam and the strut to be offset relative to the axis of the positioning post, and the miscellaneous piece increases the rigidity between the beam and the support. - for the purpose of Dashun, the _micro-architecture is disposed between the beam and the pillar of the double-drive co-positioning platform, including - positioning post and at least two

[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 beam A1 and the pillar A2 can be relatively pivoted; 20, the beam A1 and the pillar A2 are respectively connected by the radial direction of the positioning post 10, and wherein the two locking pillars 20 are connected to the beam A1 and the pillar A2 from one side of the beam A1, and the other two columns 20 are connected by the beam The other side of the 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 extend through the supporting column A2 at this end and lock the beam. In the A1, the elastic member 30 is disposed on each of the lock cylinders 20, and the elastic members 30 are disposed on the lock cylinders 20, and the elastic members 30 are disposed on the lock cylinders 20, and the elastic members 30 are disposed on the lock cylinders 20 20 between the pillar A2, another elastic member 30 is located between the beam A1 and the pillar A2, wherein the four elastic members 30 On the side of the beam A1, the other four elastic members 30 are located on the other side of the beam A1.

When the displacement error occurs between the beam A1 and the two branches of the double-drive co-positioning platform A, since the beam Α1 and the pillars 2 are connected by the positioning column 1, the lock columns are adjusted. The depth of the yoke is combined with the depth of the yoke to allow relative pivoting between the shovel beam Ai and the struts 2 to provide positional compensation between the beam Α1 and the struts 2, preventing the double drive When the truss A1 pivots relative to the struts A2, as shown in Fig. 7, the elastic member 3() on the side of the beam A1 is compressed, and the compressed elastic member 30 will Resisting the relative pivoting of the beam M and the support μ with its elastic restoring force to increase the rigidity between the beam A1 and the button A2, and the elastic members 3G have a maximum value of deformation, so when deformed After the elastic member 30 reaches the maximum value of the deformation, the user can be reminded that when the beam A1 and the pillar A2 continue to pivot relative to each other, the double-driver and the second platform A will be twisted and deformed, and the reminder is used.
