Biaxial rotation type locater

Abstract

The present invention provides a biaxial rotation type locater, capable of trying for miniaturization of the locator regardless of the sizes of drive sources. The biaxial rotation type locater (P1) includes a workpiece table (100), a first drive source (102) and a second drive source (202), the rotation of the first drive source (102) is outputted from a first rotary member (151) with a horizontal first rotating axle (X), the rotation of the second drive source (202) is outputted from a second rotary member (251) with a second rotating axle (Y) which is vertical to a table board (100A) of the workpiece table (100), the workpiece table is connected to the first rotary member (151) and the second rotary member (152) so as to rotate around an axis that is parallel to the first rotating axis (X) and around the second rotating axis (Y), and an axis (220) of the second drive source (202) is orthogonal with the second rotating axis (Y).

Description

technical field [0001] This application claims priority based on Japanese Patent Application No. 2009-153685 filed on June 29, 2009. All the content of the application is used in this specification by reference. [0002] The invention relates to a dual-axis rotary positioner. Background technique [0003] In Patent Document 1, it is disclosed as Figure 7 Two-axis rotary positioner 1 shown. Figure 8 The periphery of the second reduction gear 12 is shown. [0004] The biaxial rotary positioner 1 includes a workpiece table 13 , a first drive source 3 , and a second drive source 8 . While outputting the rotation of the first driving source 3 from the first rotating member (output member of the first reducer 7 ) 6 having the first horizontal rotating shaft A, the second rotating shaft perpendicular to the table surface 13A of the workpiece table 13 is outputted. The second rotating member (output member of the second speed reducer 12 ) 11 of the shaft B outputs the rotation...

AI Technical Summary

Problems solved by technology

Therefore, if the second drive source 8 is arranged in parallel with the second rotation axis B, when the output torque of the second drive source 8 is to be increased, the second drive source 8 will inevitably become longer in the axial direction ( large), and there is a problem that the axial dead zone on the opposite side of the table surface of the workpiece table 13 becomes larger

In addition, since the axial size around the workpiece table 13 becomes very large, when the workpiece table 13 rotates around the first rotation axis A, the peripheral parts of the second drive source 8 collide with the main equipment such as an industrial robot or peripheral parts. danger

[0008] In the above-mentioned Patent Document 1, the second driving source 8 is arranged outside the radial direction of the second speed reducer 12 to avoid this problem, but as a result, not only the size of the work table radial direction near the second speed reducer 12 When R1 becomes larger and the second driving source 8 is further enlarged, the axial length L1 has to be increased accordingly.
