Gear holder with hemispherical structure
The invention relates to the technical field of auxiliary photographic devices, in particular to a gear holder with a hemispherical structure, which comprises a holder base, a holder center shaft and a worm wheel adjusting mechanism, the holder center shaft is provided with a containing cavity, a hemispherical seat is inserted in the containing cavity, the hemispherical seat is provided with a semi-concave ball groove, the gear holder further comprises a hemisphere and a clamping seat, the hemisphere extends into the semi-concave ball groove, and the worm wheel adjusting mechanism is arranged on the clamping seat. The shooting angle of the photographic equipment is adjusted by driving the hemisphere to swing in the hemisphere base, compared with a swing adjusting mechanism in the prior art, the center of gravity of the photographic equipment can be lowered, the shooting process is more stable and safer, the overall size of the holder is reduced, and storage and carrying are facilitated; the hemisphere of the holder can swing like a tumbler in the hemisphere seat, so that the camera can be adjusted to be horizontal within a certain range or the shooting angle of the camera can be adjusted through rapid rotation, and the holder is outstanding in convenience.

Intelligent robot joint driven by planetary roller
This invention relates to a planetary roller driven intelligent robot joint, belonging to the field of intelligent robot technology. It features an active, controllable sealing assembly consisting of a sealing strip and a sealing cylinder, with the sealing cylinder integrated into the outer wall of a fixed block. The sealing strip is installed in a sealing groove communicating with the sliding block, allowing the sealing strip to actively extend and retract according to the sliding block's movement. When the sliding block retracts inward to reset, the sealing strip is compressed and deformed, tightly adhering to the outer wall to achieve a dynamic seal. When the sliding block extends outward, the sealing strip releases the compression and springs back to its original shape while maintaining a sealing fit. This transforms the passive alternating friction caused by traditional interference fits into active, time-division controllable contact, fundamentally avoiding fatigue aging and failure caused by the long-term alternating deformation of the sealing strip with the sliding block.

An ultrasonic vibration-based press-in bush press-fitting device
This invention discloses a press-fitting device for bushings based on ultrasonic vibration, comprising a frame base, a hydraulic cylinder, a transducer assembly, a mandrel, and a clamping assembly. The hydraulic cylinder is mounted on the frame base to provide axial pressing force. The transducer assembly is mounted on the output end of the hydraulic cylinder to generate high-frequency mechanical vibration and transmit it to the mandrel. The mandrel has a tapered feature for inserting into a bushing pre-placed in the inner hole of the workpiece. The clamping assembly is mounted above the frame base to clamp and fix the workpiece. The hydraulic cylinder drives the transducer assembly and the mandrel to move axially, and the high-frequency vibration is transmitted through the mandrel to the contact interface between the mandrel and the bushing, converting static friction into dynamic friction and reducing pressing resistance. This invention also includes a movable joint assembly for flexible connection, a pressure sensor for real-time monitoring of the pressing force, and a rubber clamping plate for adaptive centering in the clamping assembly. This invention effectively reduces pressing force and improves pressing quality and efficiency.
