The invention relates to a dental orthodontic archwire bending robot. The robot mainly comprises a pedestal, an orthodontic archwire feeding mechanism, an orthodontic archwire rotation mechanism, an orthodontic archwire clamping and supporting mechanism and an orthodontic archwire bending module, wherein the orthodontic archwire feeding mechanism is fixed on the pedestal, and an orthodontic archwire rotating motor is connected with the orthodontic archwire feeding mechanism through an L-shaped support frame of the orthodontic archwire rotating motor, so that rotation and feeding of an orthodontic archwire can be realized; the orthodontic archwire clamping and supporting mechanism consists of an orthodontic archwire clamping mechanism and a supporting mechanism, and is used for avoiding vibrating in an orthodontic archwire bending process; the orthodontic archwire bending module consists of an orthodontic archwire bending module position adjustment mechanism, a synchronous cog belt transmission mechanism and an orthodontic archwire bending module, and the spatial three-dimensional bending of the orthodontic archwire can be realized under cooperation of the orthodontic archwire feeding mechanism and the orthodontic archwire rotation mechanism. The dental orthodontic archwire bending robot has a simple structure, quantified bending of hyperelastic orthodontic archwires can be realized, and the bending efficiency and accuracy of orthodontic archwires can be improved.

The invention relates to a wiper. According to an embodiment of the invention, the wiper comprises a wiper blade (600), a supporting rod assembly (500) and a cover portion (400), wherein the wiper blade (600) wipes a wipe surface directly; the supporting rod assembly (500) supports the wiper blade (600); and the cover portion accommodates the supporting rod assembly (500). The cover portion (400) comprises a fixed cover portion (410) and more than one movable cover portions (420) which can pivot relative to the fixed cover portion (410). As a result, when the movable cover portions (420) pivot, gaps between the fixed cover portion (410) and the movable cover portions (420) are minimized.

A wearable tremor reduction device reduces tremor by internally generating forces which cancel or reduce the magnitude force of the tremor experienced by the person wearing the device. The device maybe worn on a wrist, arm, ankle or leg. The device has a plurality of housing members which are flexibly connected together. Each housing member contains a mass which is translatable along an axis between a proximal limit and a distal limit, and a neutral position midway between the proximal limit and the distal limit. Following imposition of a force having a component along the axis, a biasing means returns the mass to the neutral position.

The invention relates to the technical field of friction equipment, and discloses a rotary tool head and a floating device. The rotary tool head comprises a mold frame structure, a rotating structure and a tool head, wherein the rotating structure drives the tool head to rotate. The rotary tool head is characterized in that the rotating structure comprises a rotating mechanism and a transmission shaft, the rotating mechanism drives the transmission shaft to rotate through a transmission key, the transmission shaft is axially separated from the rotating mechanism, a gap is reserved between the transmission shaft and the rotating mechanism, the transmission shaft can move in the axial direction, the transmission shaft is connected with the tool head, a floating structure is arranged on the outer side of the transmission shaft in a sleeving mode, the transmission shaft is connected with the mold frame structure through the floating structure, the transmission shaft and the tool head slide in the axial direction along with the floating structure, and the advantages that the service life of the tool head is long and the blank forming quality is good are achieved.

The synchronizing device (1) has a synchronizing body (4), which is fixed on a gearbox shaft in a torque-proof manner and has external teeth (8). A sliding sleeve (9) has inner teeth (10) and is coupled with a toothed gear. A synchronizing ring (11,12) is provided with one or multiple axially aligned lugs, which have radial and axial metallic outer surfaces (15,16,17,18). The radial outer surfaces have a damping coating (20), which has a plastic coating, elastomer, polytetrafluoroethylene, polyamide, particularly polyamide 66 and polyphthalamide.

The invention provides a support device for processing a thin-wall part and a method for processing the thin-wall part. The support device comprises a mounting base, a plurality of buffering devices and a plurality of support parts, wherein the buffering devices are arranged on the mounting base and arrayed along the peripheral direction of the mounting base at intervals; the support parts are respectively connected with the buffering devices; each support part is equipped with a support surface for supporting the thin-wall part; the buffering devices are used for buffering the thin-wall part supported by the support parts. The method for processing the thin-wall part comprises the following steps: mounting the thin-wall part on a flexible multi-point mold and shaping; adopting a flexible clamp for clamping the periphery of the thin-wall part and utilizing an overturning assembly to overturn the thin-wall part from the horizontal position to the vertical position; utilizing a moving assembly to convey the thin-wall part to a processing area of a five-coordinate numerical control milling device; supporting the thin-wall part by the supporting device connected with a swinging head of a five-coordinate numerical control milling system; milling the thin-wall part by the milling device. The support device and method for processing the thin-wall part, provided by the invention, are used for solving the deforming problem of the thin-wall part in the processing process.
