In the structural design of other multi-degree-of-freedom robots or mechanical arms similar to the above-mentioned robots, the base of the robot or mechanical arm can only complete the rotation in a single plane. To complete more complex actions or increase the degree of freedom, it is usually necessary to increase the steering gear However, increasing the number of steering gears will complicate the control and structural design, and due to the action requirements, the steering gears need to be powered on and off frequently or switch forward and reverse frequently.
Repeated steering switching and frequent power on and off will cause the steering gear to shake easily, causing the steering gear and chips to be easily damaged

Disclosed is a mechanism for mechanical steering control of a steering gear. A reversing gear bracket (18) is fixedly connected on a base (20), and a gear reversing system composed of a reversing gear wheel (14), a reversing gear shaft (15), a reversing pinion (16) and a reversing pinion (17) is mounted on the reversing gear bracket (18); a tooth coupling (13) is nested in an unthreaded hole of a sun gear bracket (12) and connected with a sun gear (10); the sun gear (10) forms a sun gear train with a turntable bearing ring gear (11) through three planet gears (37); two worm shafts (2), a clutch magnet (6), a worm reversing gear wheel (33), a worm reversing gear shaft (34), a worm reversing pinion (35), a worm reversing pinion (36) and a thrust bearing (9) are mounted on a rotary support (3); a clutch gear (8), the clutch magnet (6) and a clutch gear (4) sleeve a spindle (30).
Description
technical field [0001] The invention relates to a robot structure, in particular to a mechanism for mechanically controlling the steering of a steering gear. Background technique [0002] In actual production work, such as related operations on the production line used in automobile manufacturing, EOD work, nuclear leakage treatment, etc., robots or mechanical arms are often used to replace human operations, which not only improves work efficiency, but also avoids human operations. posed risks. The mechanical arm is the core component of these robots or it is a complete industrial product itself. There are also robotic arms used in dancing robots, food delivery robots, and sales robots. The base of the robotic arm is to realize the overall movement of the robotic arm. An essential component for revolving motion in the horizontal plane. The base of a common robotic arm is usually equipped with a steering gear, which is responsible for the forward rotation and reverse rotati...
