The invention discloses a fixing mechanism and an electronic device capable of disassembling an expansion card module. The fixing mechanism comprises a substrate, a latch element and an elastic component, wherein the substrate comprises a connection part, a chute structure and a containing part; the chute structure is arranged on the connection part; the expansion card module moves relative to the connection part along the chute structure; the containing part is arranged on one end of the connection part; the latch element is pivoted in the containing part and rotates relative to the containing part to switch a first position and a second position; the latch element comprises an abutting part and an ejection part, wherein the abutting part applies pressure to one side of the expansion card module when the latch element is switched to the first position; the ejection part is connected with the abutting part in a bending way; the ejection part applies pressure to the other opposite side of the expansion card module when the latch element is switched to the second position from the first position so as to push the expansion card module to move along the chute structure; and the elastic component is positioned in the containing part to trigger the latch element, and the elastic component drives the latch element to rotate to stay at the second position. The fixing mechanism has the advantages of being simple in structure, convenient in assembling and easy in operation.

[Problem] To prevent, using a simple seismic isolation structure, vibration, noise, and overturning of a heavy object arranged on a floor surface where an anchor bolt cannot be used. [Solution] A seismic isolation structure (11) for a machine (1), wherein a plastically deformable support body (16) is buried in a gel-like elastic body (15) in a vibration-damping pad (12). A rear-surface adhesive layer in the gel-like elastic body (15) is bonded to the floor surface, and a pressurizing plate (13) is bonded to a surface adhesive layer of the gel-like elastic body (15). The pressurizing plate (13) receives the weight of the machine (1) and applies pressure uniformly to the entire vibration-damping pad (12). The base (21) of a holder (14) is welded to the upper surface of the pressurizing plate (13); a bolt (22) vertically installed on the base (21) is caused to penetrate a through-hole (3) in a leg section (2); and the leg section (2) is confined upon the pressurizing plate (13), by the holder (14), so as to be horizontally immovable.

The electric machine tool main shaft with static pressure liquid bearing for floating bearing includes front bearing, main shaft and back bearing, and the main shaft has its two end supported separately onto the front bearing on the front bearing seat and the back bearing on the back bearing seat. Between the back bearing and the back bearing seat, there is back bearing floating sleeve, in the inner wall of the back bearing seat to contact with the back bearing floating sleeve, there are several oil cavities serving as static pressure bearings, and the oil cavities are communicated with the oil system vian oil path. The present invention can ensure the rotation precision and rigidity of the main shaft, and has simple structure, small amount of parts and easy machining.

The invention provides a pressurizing oil cylinder tail end flexible connecting device and a rotary drilling rig. The pressurizing oil cylinder tail end flexible connecting device comprises a connecting seat, a damping elastic member and a connecting rod suitable for connecting a mast of the rotary drilling rig with the tail end of a pressurizing oil cylinder, the connecting seat comprises a firstconnecting portion and a second connecting portion, the first connecting portion is provided with a mounting hole, and the second connecting portion is used for being connected with the mast of the rotary drilling rig. The damping elastic member is fixed in the mounting hole and provided with a buffering hole for containing the connecting rod and can be abutted against the outer wall of the connecting rod to lower vibration of the pressurizing oil cylinder. The device can effectively absorb vibration and impact of the pressurizing oil cylinder during working, and the problem that the connecting device and fixing bolts are prone to being damaged can be improved; working conditions of sealing structure inside the pressurizing oil cylinder can be improved, and service life of the pressurizing oil cylinder is prolonged. Therefore, service life of the rotary drilling rig is longer.

The invention relates to an active compensation type visual alignment stacking robot and an alignment compensation method thereof, including a transmission component and an intelligent grabbing component. The intelligent grabbing component includes a displacement drive mechanism, a basic gripper mechanism, a lifting mechanism, and a visual alignment unit. The lifting mechanism provides lifting power for the jaws, and the displacement drive mechanism provides horizontal power for the intelligent grasping components as a whole; the basic jaw mechanism provides clamping and loosening power for the splint through a worm gear reducer motor and a pair of screws with opposite rotation directions; Use the workpiece position sensing unit to measure the distance between the current gripper and the cargo in real time, and sense whether there is a cargo below, and at least four workpiece position sensing units installed at the four corners to work together to determine whether the currently clamped cargo is located in the position of the existing cargo Directly above. The workpiece position sensing unit cooperates with the power trolley and the lifting mechanism to self-adjust and compensate according to the sensing signal of the workpiece position sensing unit, so as to avoid the dumping of goods caused by stacking errors.

The invention discloses a nano film forming machine for preparing nano functional film, which comprises a vacuum tank body and a generator, the vacuum tank body comprising a cabin and a top cover which is equipped with the cabin, the generator being equipped with the inner of the cabin and being fixed by a supporting flange which is equipped with the cabin, the rotation shaft of the generator being provided with a base-tray, the top cover being equipped with a liquid inlet which locates above the base-tray, the vacuum tank body being equipped with a vacuum adapter for evacuation, in the vacuum tank body being provided with a heat source for thermal dissociation and a light source for photo dissociation, and the heat source and light source equipped upper than base-tray; the invention has a merit of: taking film formation, thermal dissociation or photo dissociation and phase-change in high temperature in a whole body, and guaranteeing the film quality.
