This invention discloses an automated scanning, acquisition, and processing device for in-situ core logging data, relating to the field of oil and gas geological exploration technology. It includes: a sampling and analysis platform; a support device horizontally fixed to the sampling and analysis platform, on which a core is placed; a positioning and analysis device fixed to the sampling and analysis platform, located behind the support device and in contact with the top of the core; a protective cover fixedly connected to the rear wall of the sampling and analysis platform, located above the core, with a through-hole in the middle and multiple white light tube groups on the inner walls of the front and rear sides; and an equidistant sampling device fixed to the top of the protective cover, corresponding to the positioning and analysis device. This invention integrates sampling, scanning, and analysis, achieving efficient acquisition and accurate processing of core logging data, and improving the reliability of geological modeling.

This invention discloses a welding workbench for automotive turbochargers based on standardized processing, belonging to the field of turbocharger welding technology. It includes a base, on which a rotary chuck is slidably mounted. A pneumatic chuck is mounted on the side of the base away from the rotary chuck via a bracket. A first electro-hydraulic rod, connected at one end to the rotary chuck, is mounted on the side of the base away from the pneumatic chuck. Through the design of the base, chuck, auxiliary unit, and positioning unit, the invention precisely solves the technical pain points of traditional workbench use, such as cumbersome processing of extruded plastic metal and unstable clamping. The corresponding arrangement of the rotary chuck and pneumatic chuck achieves precise docking of the turbine shaft and turbine impeller. In conjunction with the second electro-hydraulic rod of the positioning unit, the upper pressure seat, the lower clamping seat, and the transmission engagement of the gear and rack, the turbine impeller, fixed by the pneumatic chuck, can be clamped in a wrap-around manner, effectively preventing radial runout of the impeller during high-speed rotational friction.
