A magnetic transmission automobile air conditioner electromagnetic clutch is structurally composed of a belt pulley, a driven disc, a compressor shaft, a compressor shell, a bearing and a coil. The internal combustion engine drives the belt pulley to rotate; when the air conditioner does not need to work, the coil is not electrified; no magnetic force exists between the belt pulley and the driven disc, and the compressor does not work. When the air conditioner needs to work, the coil is powered on; magnetic forces which attract each other are formed at air gaps among the pulley rim magnetic conductive teeth, the teeth of the driven disc outer magnetic conductive gear ring, the pulley spoke magnetic conductive teeth, the teeth of the driven disc inner magnetic conductive gear ring and the pulley hub magnetic conductive teeth, and the magnetic forces drive the driven disc and the pulley to rotate together, so that the compressor works.

This invention discloses an intelligent displacement-type straw stacking device with compaction function, belonging to the technical field of straw stacking devices. It includes a base, a pressing assembly, an adjusting assembly, a guide cylinder, an electric rotating drum, and a guiding assembly. During the edge expansion process, the movable side column drives the bottom adjusting component to move synchronously to both sides. Through the cooperation of the sliding column and the inclined groove, the drive roller and the detection roller achieve stable clamping of the row of straws. After the detection roller and the drive roller clamp the row of straws, under the drive of a second motor, the detection roller and the drive roller rotate synchronously through transmission components such as gears, force transmission rings, and arc-shaped piston rods, applying a stable downward traction force to the row of straws, pulling out the blockage material in the expansion channel and achieving deblocking. After deblocking is completed, the control system automatically resumes the operation of the electric rotating drum and reverses the drive of the edge expansion assembly and the deblocking and anti-breakage assembly to reset, achieving seamless connection between the deblocking process and normal feeding, avoiding prolonged equipment shutdown due to material blockage.

The utility model discloses a transmission assembly with a damping type clutch structure, which comprises a transmission shaft part, a rotary transmission part capable of rotating relative to the axial direction of the transmission shaft part is connected onto the transmission shaft part, and a clutch part positioned on one side of the rotary transmission part is further connected onto the transmission shaft part. The clutch part is connected to the transmission shaft part in a sliding mode in the axial direction and can rotate along with the transmission shaft part, so that the clutch part can be attached to or away from the rotary transmission part in the axial direction, and a pre-tightening force elastic element capable of providing pre-tightening force to push the clutch part to be attached to the rotary transmission part is further arranged between the transmission shaft part and the clutch part. A clutch structure is arranged between the rotary transmission part and the clutch part, when the torque of the rotary transmission part and the clutch part is smaller than a preset value, the rotary transmission part and the clutch part are in close transmission, and when the torque of the rotary transmission part and the clutch part is larger than the preset value, the clutch part is separated from the rotary transmission part. The transmission assembly with the damping type clutch structure is compact in structure and good in protection effect.

The utility model discloses a socket structure with an overload protection function, which comprises a device main body and an overload protection mechanism, and the overload protection mechanism is arranged at the upper end of the device main body and used for power-off protection. The overload protection mechanism comprises a rear machine cover, one end of the rear machine cover is provided with a machine box, an inner supporting piece is installed in the machine box, and one end of the inner supporting piece is provided with an induction piece. And the safety of the device main body is improved, and the effect of prolonging the service life of the device main body is achieved by installing a protection mechanism at one end of the device main body.

This invention discloses a small-diameter motor-driven dual-mode intelligent honing tool integrated into a machining center, along with its operation method and application, belonging to the field of precision machining. The honing tool includes a tool body, a honing stone assembly, a motor-driven feed mechanism, a conductive slip ring, a protective cover, and a motor control system. The motor-driven feed mechanism is integrated within the tool body, driving the axial movement of the pusher rod through a reduction gearbox and a lead screw pair, and using the conical surface to drive the radial expansion and contraction of the honing stone. The motor control system employs dual-mode intelligent control: quantitative rough honing based on encoder position feedback, and constant-pressure fine honing based on a motor current-honing force model, thus achieving precise closed-loop control of the honing process. The conductive slip ring ensures power supply for rotation, and the protective cover provides anti-rotation and sealing. This honing tool can complete drilling, reaming, and honing composite machining in a single setup, solving the problems of low pressure control accuracy and slow response of traditional hydraulic tools, and is particularly suitable for ultra-high precision parts such as electro-hydraulic servo valve sleeves.

This invention relates to the technical field of force measurement platforms, and more particularly to a human posture data acquisition device and its assembly method, comprising a support platform and several detection pillars supported on the edge of the support platform; each detection pillar includes a platform clamp and a detection base, with a distance difference between them; the platform clamp and the detection base are connected by a decoupling structure to transfer stress, and when a vertical force is applied to the support platform, the decoupling structure absorbs additional interference stress and provides overload protection through its own flexible deformation; a connecting structure is provided between the platform clamp and the detection base to prevent the platform clamp from detaching from the detection base, and at least one end of the connecting structure forms a non-rigid connection with the platform clamp or the detection base; the detection base is used to capture stress from the support platform and passing through the decoupling structure, and the decoupling structure of this invention absorbs additional interference stress and provides overload protection through its own flexible deformation.
