The invention relates to a plate bending machine capable of automatically adjusting multiple groups of upper supporting roller devices, which belongs to the technical field of structures of super wide plate bending machines. Each group of upper supporting roller device is hung on the lower end of a beam through a spring, and the upper ends of the upper supporting roller devices are fixedly connected with fixed longitudinal lower inclined irons; the lower ends of both heads of the beam are respectively fixedly connected with oil tanks, telescopic links of the two oil tanks are coaxially opposite and parallel to upper rollers, a connection beam is connected between the two telescopic links of the two oil tanks, longitudinal upper inclined irons are uniformly distributed on the connection beam, and the lower surface of each longitudinal upper inclined iron is respectively contacted with the upper end surfaces of the corresponding fixed longitudinal lower inclined irons; the front side and the rear side of the lower end of the beam are respectively fixed with positioning seats, two inner lateral surfaces opposite to the positioning seats are respectively provided with vertical key slots, and the front side and the rear side of each group of upper supporting roller device are connected with the positioning seats through guide keys inside the key slots. The invention can fast synchronously adjust the multiple groups of upper supporting roller devices, reduce the time of plate bending preparatory processes, enable the plate bending operation to be more convenient and enhance the precision of plate bending products.

The invention discloses a fixing device for motorcycle engine end cover processing, which comprises a base. The inside is provided with a thread groove, and the thread groove is screwed and connected with the external thread on the surface of the fixing seat. The upper surface of the gland is provided with a through hole, and the through hole communicates with the thread groove. The inside of the fixing seat is provided with A counterbore, the counterbore is arranged vertically, and a column is arranged inside the counterbore, and the column vertically extends through the through hole to the outside of the gland. The present invention adopts two oppositely arranged clamping mechanisms, and adopts the up-and-down expansion and contraction of the column and the horizontal opposite movement of the screw rod to realize the clamping of the workpiece, which can achieve effective and stable clamping of workpieces with various shapes, and is convenient for multiple angles of the workpiece The adjustment improves the workpiece clamping range and effectively improves the processing efficiency.

Two-side-driven rotary tillage soil-preparing machine, comprising transmission assembly and knife roller assembly, wherein the transmission assembly comprises an intermediate transmission box and left and right two side transmission boxes. A power input shaft and a differential connected to rear power output of the tractor through cardan joint are fixed in the intermediate transmission box, wherein a transmission gear is fixed on casing of differential and an input bevel pinion is mounted on the power input shaft, and the transmission gear and the bevel pinion transmit through gears. The differential has a structure that four orthogonal angle gears are fixed in the casing, wherein each of the two angle gears at left and right is connected with an output half shaft respectively of which outer end is connected to a drive gear in each of the two side transmission boxes respectively. When tooth spaces of gears in the left and right two side transmission boxes are not on a same line, the two angle gears at left and right in the differential would be lightly turned under the action of torque to make the drive gears in the two side transmission boxes normally work, thereby making knife roller assembly normally rotate. The soil-preparing machine has the advantages of gravity balance in whole body, fine stability and flat ground surface after ploughing.

The invention disclsoes a flue smoke exhaust system. The flue smoke exhaust system comprises a public flue, a range hood, a smoke pipe and a fireproof valve, an air outlet of the range hood communicates with the public flue through the smoke pipe and the fireproof valve, and the fireproof valve comprises a valve body installed at the outlet end of the smoke pipe and a valve plate installed on thevalve body; and the flue smoke exhaust system is characterized by further comprising an electromagnetic chuck and a power detection socket, wherein the electromagnetic chuck is used for sucking the valve plate at the maximum opening angle, the electromagnetic chuck is electrically connected with the power detection socket so that the power detection socket can supply power to the electromagnetic chuck, and a plug of the range hood is inserted into the power detection socket so that the power detection socket can detect the power of the range hood. According to the flue smoke exhaust system, the valve plate is sucked through the electromagnetic chuck, so that the valve plate is not prone to swinging due to airflow interference, the power of the range hood is detected through the power detection socket, the magnitude of output current of the electromagnetic chuck is fed back and compensated, then the electromagnetic force is adjusted, and the insufficient air pressure condition caused bysudden air volume change due to range hood gear change is compensated so that the wind pressure and the magnetic force can balance the gravity of the valve plate.

The invention discloses a power maintenance tool dispensing device for changing an elastic component pressure regulating stabilizer through hand sorting. An external hand wheel handle rotates with a hand wheel rotation circle; a butt-joint rod is connected to a rotation drum to drive the whole interior of the device to operate, and a gear sleeving the rotation drum to rotate synchronously; a gearchain drives movable dispensing boxes to operate synchronously through the gear, and allows box cover telescopic plates to automatically open and close through elastic components; sliding blocks can change the internal air pressure of the boxes through gravity changing, clamping blocks and clamping grooves are in opening and closing connection, the internal adsorption force becomes larger, the internal weight of the boxes is balanced to prevent shaking off; since a convex positive magnetic ring and a convex negative magnetic ring at the front end of the gear attract each other to drive rotation, and the manual rotation load is reduced; during rotation, tools in each dispensing box can be viewed at a window, manual operations can be allowed, the operations can be repeated, the practicability is high, storage and searching are facilitated, and time and effort can be saved.
