39results about How to "Uniform contact force" patented technology

A twist pin is used as an interconnect interface to conduct signals to and from an electronic component. The twist pin includes a bulge which establishes compressive contact force with a sidewall of a via in which the twist pin resides, and the resulting force resists movement of the end of the twist pin away from the electronic component to assure good signal conductivity. The arrangement may be used as a test socket for testing integrated circuit components or permanently docking electronic components.

A rotor for an electric switch is disclosed. In an embodiment, the rotor includes a rotor housing and a rotatably mounted contact bridge, which exhibits two movable contacts, wherein, by the rotation of the rotor, the two movable contacts can interact with two fixed contacts of an electric switch for closing or opening a circuit. The rotatably mounted contact bridge in the rotor housing is movably mounted in a direction perpendicular to the direction of the contact bridge in its closed position.

Sealing structure for use in creating a seal between an elevator drive shaft and a loadlock chamber includes a base fastened over a hole in the bottom wall of the loadlock chamber, a fixed member fastened to an upper part of the base, a seal housing spaced above the fixed member, a cap in the form of a flexible bellows having a first end adhered to an upper surface of the fixed member and a second end adhered to a lower surface of the seal housing, one or more support shafts having upper and lower ends pivotally connected to the seal housing and the fixed member outside the cap, a seal seated in the seal housing and having an inner circumferential surface contacting the outer circumferential surface of the elevator drive shaft, and a seal cover fixed to an upper part of the seal housing. According to the present invention, uniform pressure is maintained between the shaft and the seal during assembly and operation of the apparatus. Thus, a seal is always maintained between the elevator drive shaft and the bottom wall of the loadlock chamber.

The invention relates to a stamping machine, and belongs to the mechanical field. The stamping machine comprises a drive gear and a driven gear, wherein the drive gear is connected with a rotary shaft of a motor through a transmission device; the driven gear is fixed on a crankshaft; the drive gear transfers power in a manner of being engaged with the driven gear; the working surfaces of gear teeth on the drive gear are arc-shaped; arc-shaped grooves are arranged in the driven gear; the inner surfaces of the grooves are in close fit with the outer surfaces of the gear teeth when the grooves are engaged with the gear teeth. The gear teeth have the arc surfaces, the gears are engaged through the arc surfaces, the gear teeth form contact through the arc surfaces during the engagement process, and stresses on the parts of the gear teeth are uniform to prevent hard collision among the teeth.

The invention discloses a stabilizer and a manufacturing method thereof. The manufacturing method comprises the following steps that: hard alloy blocks are first welded on an edge band matrix by adopting a spot welding way; afterwards, spray welding is carried out on the edge band matrix around the hard alloy blocks by adopting a flame spray welding gun; burnt-out alloy powder sprayed out from the welding gun and the edge band matrix are melted integrally to form alloy powder melted layers around the hard alloy blocks; the hard alloy blocks are fixedly arranged on the edge bank matrix firmly; and after a spray-welded layer covers all the hard alloy blocks, the stabilizer is fed onto a cylindrical grinding machine to be subjected to cylindrical grinding, so that each hard alloy block is ground to be exposed and reach the diameter dimension of the outer circle of the needed stabilizer, thereby obtaining the stabilizer. The stabilizer not only has the advantages of being simple in structure and being easy to manufacture, but also has the advantages of high dimensional precision, high abrasive resistance, long service life and the like.

The invention discloses an obstacle removal type intelligent vehicle system based on laser distance measurement. A vehicle body is driven to move in a track manner; wheels adopt right-angled steering speed reducing motors; a mechanical arm is mounted on a turntable base in the center of the vehicle body; the turntable base is of an all-aluminum alloy structure; a rotating part is a steel ball bearing, so that the arm can freely rotate; the mechanical arm is a six-degree-of-freedom arm, and a hard aluminum alloy two-degree-of-freedom mechanical jaw capable of grabbing objects is arranged at the tail end of the mechanical arm; the mechanical arm can be used for conventional grabbing operation, and also can autonomously remove non-fixed obstacles to develop an advancing road; the moving plan of the mechanical arm adopts a D-H coordinate system analysis method; the distance measurement adopts a pulse laser distance measurement system; and an emitting module, a receiving module and an MCU module for data processing are used for quickly removing any obstacle to measure the distance, so that the system reliability is improved. The system combines the autonomous mechanical arm with the intelligent vehicle, can help people to work under special environments untouchable by manpower, and is higher in reality application value.

A rotor for an electrical switch is disclosed, comprising a rotor housing and a rotatably supported contact bridge having two movable contacts, wherein the two movable contacts can be moved by rotating the rotor. The head cooperates with the two fixed contacts of the electrical switch to close or open the circuit, wherein the rotatably supported contact bridge is in the rotor housing along a direction perpendicular to the direction of the contact bridge in its closed position The direction is movably supported.

The invention relates to a coating film supporting mechanism of a high temperature deposition hard mask of a film coating workpiece, belonging to auxiliary equipment of optical coating. The coating film supporting mechanism comprises a film coating tray, a stop dog groove, a workpiece stop dog, a locking screw, a steel ball and a steel ball caulking groove. The middle part of the film coating tray is provided with an opening for placing the film coating workpiece, the four sides of the tray are provided with radial stop dog grooves for installing the workpiece stop dog, the workpiece stop dogmoves in the groove, the inclined plane of the workpiece stop dog is embedded with a steel ball (rolling ball), the steel ball rolls in the caulking groove, the workpiece stop dog is fixed in the stop dog groove by the locking screw, the edges of the film coating workpiece are all provided with tapers, the film coating workpiece is placed on the inclined plane of the workpiece stop dog and contacts with the steel evenly, and then the film coating workpiece and the entire device are both placed into a circular ring tray of the film coating machine. The mechanism of the invention can ensure that uniform force is exerted on each steel ball and the workpiece, the position of the stop dog can be freely adjusted in a certain scope according to the dimension of the workpiece; in addition, the chucking power for adjusting the workpiece can be provided by expansion or shrinkage force generated from high temperature or low temperature to drive the steel ball to roll; and the mechanism of the invention features in simple structure and high cost performance.
