This utility model discloses a forging stress detection device, relating to the field of materials science and technology. The device includes a base with a support frame fixedly connected to its top. A fixing mechanism is mounted on the base, and a detection mechanism is mounted on the support frame. The fixing mechanism includes a limiting ring, with a threaded rod rotatably connected to the inner wall of the limiting ring. By incorporating a soft pad, rotating a knob causes the threaded rod to rotate, which in turn moves a threaded cylinder downwards along the threaded rod. This threaded cylinder then pulls a connecting rod downwards, which in turn pulls the moving blocks closer together. The soft pad, which clamps and fixes the forging, effectively isolates it from external vibrations and the vibrations of the testing equipment, preventing displacement due to insufficient fixation and ensuring the accuracy of the test results.

This invention discloses a rope-driven anthropomorphic wrist joint with rotational decoupling characteristics, belonging to the field of robotics technology. It includes a rotational decoupling mechanism and a differential mechanism. In the rotational decoupling mechanism, a fixed wheel is fixed to the robot's forearm, while the driving wheel is connected to the differential mechanism. The rope assembly enables flexible drive of the joint module. The rotational decoupling mechanism employs a movable pulley system, utilizing the characteristics of the movable pulleys to decouple the motion of the two sets of steel cables as they pass through the rotational joint. This allows the drive unit to be centrally located on the robot base or near the proximal end structure. The differential mechanism consists of a differential rotation axis, a fixed seat on the outer side of the differential rotation axis, and two symmetrically arranged sets of differential rotating wheels, forming a differential structure. This enables multi-degree-of-freedom composite movements such as pitch and yaw within a limited space, significantly improving structural compactness. This invention uses a rope-driven combined with rope transmission structure, enhancing joint flexibility and effectively isolating the motor output from impact and vibration.

This invention belongs to the field of mineral flotation technology, specifically relating to a forced slurry conditioning-eddy current mineralization-static separation mineral flotation system and method. It includes a slurry conditioning cylinder, a separation chamber, and a mineralization cylinder connected in sequence. The slurry conditioning cylinder contains a slurry conditioning pipeline; the separation chamber contains raw ore processing pipelines and middlings processing pipelines; and the mineralization cylinder contains an eddy current mineralization pipeline. The slurry conditioning pipeline, raw ore processing pipeline, eddy current mineralization pipeline, and middlings processing pipeline are connected sequentially. After minerals and flotation reagents are conditioned in the slurry conditioning cylinder to obtain raw ore slurry, it passes through the separation chamber to obtain middlings ore slurry, which then enters the eddy current mineralization pipeline. The middlings ore slurry returns to the separation chamber and enters the middlings processing pipeline for flotation separation. Finally, concentrate is collected at the top of the separation chamber. The mineral flow path designed in this invention enables efficient collisions between minerals of different particle sizes and slurry conditioning reagents, as well as between minerals and air bubbles, achieving effective flotation recovery.
