The application provides a hollow coupling device for a semiconductor wafer, and a semiconductor wafer cleaning device. The hollow coupling device comprises a hollow coupling support for connecting a wafer clamping device and a driving motor. A hollow structure is arranged at the center of the hollow coupling support, and the hollow structure is used for accommodating a bearing and a hollow shaft. The hollow shaft is internally provided with a cooling water pipe. The bearing is arranged in the hollow structure and is sleeved on the outer diameter of the hollow shaft, and is used for allowing the hollow coupling support and the hollow shaft to rotate relative to each other. The application can be compatible with a heating disc added to the back of the wafer, does not increase the overall installation height of the wafer clamping device, and the hollow structure of the hollow coupling support can accommodate the cooling water pipe, so that the heating disc can be efficiently cooled.

The utility model discloses a multi-station motor magnetic shoe press-fitting machine, which relates to the technical field of motor magnetic shoes and comprises a case, a lifting module is arranged on one side of the top of the case, and a support guide part fixed at the top of the case is arranged on the outer side of the lifting module; a rotary platform is arranged on the outer wall of the other side of the top of the case; a motor rotor is arranged on the rotary platform; a rotating mechanism is fixedly mounted at the top of the lifting module, the top end of the lifting module is rotationally connected with a reversing frame, and the rotating mechanism is at least used for driving the reversing frame to rotate at the top end of the lifting module; a pressing station and a gluing station are arranged on the inner side of the top of the reversing frame. By means of rotation of the reversing frame, different machining stations can be driven to conduct transposition, gluing and press-fitting operation on the magnetic shoe of the motor rotor are achieved, the installation efficiency of the magnetic shoe of the motor is improved, rotation transposition of the reversing frame is more flexible, and more installation space is not occupied.

The utility model discloses a temperature input type signal isolator, including shell and installation portion, the shell is by half edge shell I and half edge shell II through bolt tight cover and is made, the top of installation portion has the slot for the plug -in installation shell, and has the ladder -shaped groove in the bottom of installation portion, and the both sides in the ladder -shaped groove are located with the vertical board, pass through the positioning structure between the " " shaped push frame and vertical board to make push frame relative to vertical board after moving and opposite fixed with vertical board, and with " " shaped support plate body is inserted into the aperture in the middle of guide rail for supporting, two clamping teeth are symmetrically installed in the ladder -shaped groove, and be used for clamping on guide rail. The utility model, avoided when using external bolt when signal isolation and guide rail installation fixed need extra punching and the inconvenience in the narrow space operation's disadvantages, bring the convenience to the installation and dismount of this signal isolator.

This invention relates to a steering column for a motor vehicle, comprising a housing unit in which a steering spindle is mounted and rotatable about a longitudinal axis extending in a longitudinal direction, and the housing unit comprising at least two housing tubes adjustable relative to each other in a nested telescoping manner in the longitudinal direction. The steering column includes a roller guide having at least one bearing support, the roller guide being radially displaceable on a first housing tube, and at least one roller mounted in the roller guide being rotatable about a roller axis transverse to the longitudinal axis. The roller can roll longitudinally on a second housing tube via its outer circumference, wherein a preload device interacts with the bearing support to preload the roller against the second housing tube. The invention proposes that the bearing support be guided on the first housing tube at an inclination relative to the longitudinal axis, and the preload device is designed to apply an axial force to the bearing support.
