An automobile seat rotation mechanism comprises an upper rotary disk and a lower chassis arranged opposite to each other, the upper surface of the lower chassis is provided with a fixed plate, the lower surface of the upper rotating disk is provided with a holding disk, A hold plate is provided with an accommodating space, the lower part of the fixing plate is clamped in the accommodating space, An upper portion thereof extend out of that accommodating space, An upper rotary disk is seat on an upper portion of that stationary disk, the fixed disk is provided with an annular ring gear, An upperrotary disk is provide with a gear, gear meshes with ring gear, the gear is connected with a driving device. The beneficial effect of adopting the invention is that between the rotating part of the upper part and the fixed part of the lower part, the structure form of nesting and tightening is adopted, when the upper rotating disk rotates, the gripping disk is driven to rotate together, and the gripping disk is limited by the fixed disk, so that lateral deviation does not occur, so that the rotation of the upper rotating disk is more stable.

The invention creatively discloses a tool clamp table for assembling a transformer core. The tool clamp table comprises a fixed base. Four supporting rods are welded to four corners of the top of thefixed base and hydraulic oil cylinders are spirally fixed to the top ends of the four supporting rods through a connecting upper frame. According to the tool clamp table for assembling the transformercore, limiting side racks are symmetrically welded to two sides of a hanging rack, and sliding sleeves are welded to the tops of the limiting side racks. By connecting the sliding sleeves to a supporting rack, the hanging rack which is lifted can be limited, so that the hanging rack is kept in vertical lift without lateral deviation, and therefore, the mounting precision is improved. Then, by arranging a sliding limiting rack, the sliding limiting rack can limit a transformer core group, and meanwhile, a laser positioning lamp at the bottom of the sliding limiting rack can position the transformer core group, so that the mounting position of the transformer core group is more precise.

The invention relates to a rolling type centrifugal casting machine. A first supporting seat and a second supporting seat which are used for supporting shafts are oppositely arranged on a base; a rotating shaft which extends horizontally is arranged on each of the two supporting seats; the two rotating shafts are parallel, and the heights of the two rotating shafts in the horizontal position are same; the rotating shafts are supported on the supporting seats through bearings; rollers for holding a cylinder casting mold for rotating are respectively installed at two extending ends of the rotating shaft; a driven wheel for receiving power transmission is installed at one end of the rotating shaft on the first supporting seat so as to enable the roller on the first supporting seat to be an active roller, and the roller on the second supporting seat to be a driven roller; and the spacing distance between the active roller and the driven roller is greater than the radius of the cylinder casting mold and is less than the diameter of the cylinder casting mold, thereby forming a raceway for the cylinder casting mold to rotate. The invention can enable the cylinder casting mold of which the axial length is greater than 400mm to be held by the rollers on the two supporting seats for rotating, overcomes the rotary swing of a cantilever type casting mold, realizes the purpose of carrying out centrifugal casting by using a longer cylinder casting mold, improves the production efficiency, has simple structure, and reduces the manufacturing cost of the centrifugal casting machine.

The invention discloses a glass twitch roller structure which comprises a central roller body and a twitch roller cylinder arranged on the external of the central roller body, two ends of the central roller body are respectively provided with an end shaft, the central roller body and the end shafts are made of rigid plastics and are of an integrated structure, the twitch roller cylinder is a silica glass roller cylinder, a dull polish layer is arranged on the outer surface of the silica glass roller cylinder, and abrasion-resisting layers are arranged on outer surfaces of the end shafts. Through the mode, the glass twitch roller structure is light in weight, the outer surface has definite roughness, and lateral deviation of cloth cannot be caused.

The invention provides a production device and a production method of a conductive interconnection board of a back contact battery and the conductive interconnection board, and relates to the technical field of solar photovoltaics. The device comprises a workbench used for bearing a substrate, a wiring unit used for arranging a conductive wire on the substrate, and a moving unit used for enablingthe wiring unit and the substrate to move relatively. The wiring unit comprises: a plurality of wire pipes which are arranged side by side; a first group of conveying mechanisms which are used for conveying a plurality of conductive wires into the wire tubes from the feeding positions from the inlets of the corresponding wire tubes; a cutting mechanism which is used for cutting off the conductivewire in the wire pipe to obtain a wire section; a heating and rolling mechanism which is used for rolling the wire section on a substrate to form a conductive interconnection board; and a second groupof conveying mechanisms which are used for respectively introducing the plurality of wire sections into the heating and rolling mechanism from the outlets of the corresponding wire pipes. The conductive interconnection board is low in production cost and high in production efficiency.

The invention discloses an anti-rollover metal vibration damping support, and belongs to the technical field of viaducts. The anti-rollover metal vibration damping support comprises a guide sliding seat body composed of a transverse limiting part, a locking limiting part and a bearing part, a longitudinal sliding group composed of a longitudinal sliding lower plate, an annular oblique folding spring and a longitudinal sliding upper block or a longitudinal sliding group composed of a longitudinal sliding lower plate, a disk spring and a longitudinal sliding upper block, and a guide sliding groove on the guide sliding seat body; the sliding guide group is locked and limited not to move up and down by the locking limiting part in the guide sliding seat body, the sliding guide group is limitednot to slide to two sides by the transverse limiting part in the guide sliding seat body, so that the two sides of the beam body of the viaduct which locks the supporting beam body of a single pier single support do not swing up and down, the beam body of the viaduct which locks the supporting beam body of the single pier single support does not roll over to any side, the function preventing theviaduct of supporting beam body of the single pier single support from rolling over is integrated with the function of adapting to the change of thermal expansion and cold contraction of the viaduct,and the use safety and the use stability of the viaduct are improved.

A method of and a device for operating a gas discharge lamp which is fed with an alternating voltage or an alternating current and wherein the instantaneous power of the lamp is increased at given time intervals are used to form the electrodes. The value of an operational datum of the lamp which varies in time is continuously or discontinuously measured and the frequency of the alternating voltage or the alternating current (operating frequency) is selected in dependence on the measured values.
