[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] As Figures 1-4 shown, a technical scheme provided by the utility model comprises the following steps:

[0023] A six-axis robot with a fully symmetrical workspace includes a base 1. Several legs 14 with equal arcs are arranged at the bottom of the base 1. A turntable 2 is movably mounted on the upper end of the base 1. A rotating mechanism is provided between the turntable 2 and the base 1. The rotating mechanism includes a motor 6, which is located at the bottom center of the base 1. The output shaft of the motor 6 passes through the base 1 and is fixedly connected to the bottom center of the turntable 2. The rotating mechanism also includes a ring-shaped guide rail 7, which is located at the upper end of the base 1. A slide 8 matching the ring-shaped guide rail 7 is located below the bottom of the turntable 2. A fixed platform 3 is fixedly mounted on the upper end of the turntable 2. The upper end of the fixed platform 3 is movably mounted... The system includes a mounting base 4, with a six-axis robot body 5 mounted on its upper end. A translation mechanism is provided between the mounting base 4 and the fixed platform 3. The translation mechanism includes a lead screw 9, which is movably mounted in the middle of the fixed platform 3. A movable block 10 is movably mounted outside the lead screw 9, with the top of the movable block 10 fixedly connected to the bottom middle of the mounting base 4. A second motor 11 is located in the middle left side of the fixed platform 3, with the output shaft of the second motor 11 fixedly connected to the lead screw 9. The translation mechanism also includes guide grooves 12, which are symmetrically arranged on both sides of the upper end of the fixed platform 3. Guide blocks 13 are symmetrically arranged on both sides of the bottom end of the mounting base 4, and the guide blocks 13 are slidably connected to the guide grooves 12.

[0024] In this embodiment, regarding the rotation mechanism, by mounting motor 6 at the bottom center of base 1 and connecting its output shaft to the bottom center of turntable 2, the accuracy and symmetry of the rotation center are ensured. Simultaneously, annular guide rail 7 surrounds the upper end of base 1, and slide 8 matches the annular guide rail 7, enabling turntable 2 to rotate stably 360° around the output shaft of motor 6 without dead angles, achieving full symmetry of the six-axis robot's workspace in the horizontal circumferential direction. Regarding the translation mechanism, lead screw 9 is movably positioned in the center of fixed platform 3, and motor 11 is mounted on the left center of fixed platform 3. Guide grooves 12 are symmetrically arranged on both sides of the upper end of fixed platform 3, and guide blocks 13 are symmetrically arranged on both sides of the bottom end of mounting base 4. This symmetrical structural design ensures the stability and symmetry of mounting base 4 during translation. Mounting base 4 can translate bidirectionally along the axial direction under the drive of lead screw 9, with the translation range at both ends being the same, achieving full symmetry of the six-axis robot's workspace in the axial direction of lead screw 9. The integrated design of the rotation and translation mechanisms enables the six-axis robot to achieve full symmetry in its workspace within the horizontal plane, allowing it to perform flexible, stable, and high-precision operations at different angles and positions, thereby improving the robot's work efficiency and applicability.

[0025] Working principle: Regarding the rotation of the turntable 2, after the motor 6 at the bottom center of the base 1 is started, its output shaft rotates, causing the turntable 2, which is fixedly connected to it, to rotate relative to the base 1. The slide 8 at the bottom of the turntable 2 slides on the annular guide rail 7 at the top of the base 1, providing support and guidance to ensure the stable rotation of the turntable 2. This allows the position of the six-axis robot body 5 in the horizontal circumferential direction to be adjusted. Regarding the translation of the mounting base 4, the motor 11 at the middle left side of the fixed platform 3 is started, and its output shaft drives the lead screw 9 to rotate. The movable block 10 outside the lead screw 9 moves along the axial direction of the lead screw 9. Since the top of the movable block 10 is fixedly connected to the bottom center of the mounting base 4, it drives the mounting base 4 to move. At the same time, the guide blocks 13 on both sides of the bottom of the mounting base 4 slide in the guide grooves 12 symmetrically arranged on both sides of the top of the fixed platform 3, providing guidance and limiting functions to ensure that the mounting base 4 translates linearly along the axial direction of the lead screw 9, thereby adjusting the position of the six-axis robot body 5 in the axial direction of the lead screw 9. The robot's fully symmetrical workspace is achieved thanks to the symmetrical design of its rotation and translation mechanisms. In the rotation mechanism, the annular guide rail 7 is circular and centrally symmetrical, the slide block 8 can slide 360° in a circle, and the motor 6 is installed at the bottom center of the base 1 to ensure accurate symmetry of the rotation center, making the six-axis robot body 5 fully symmetrical in the horizontal circumferential direction of the workspace. In the translation mechanism, the lead screw 9 is in the middle of the fixed platform 3, the motor 11 is installed in the middle of the left side, the guide groove 12 and the guide block 13 are symmetrically arranged, and the mounting base 4 can translate in both directions with the same translation range at both ends, making the six-axis robot body 5 fully symmetrical in the axial direction of the lead screw 9. Together, these features make the robot fully symmetrical in the horizontal plane, enabling it to operate flexibly at different angles and positions, improving work efficiency and applicability.
