30results about How to "Shorten the assembly period" patented technology

The invention is directed to maintaining the accuracy in the positional adjustment of a stationary part while shortening a turbine assembly period through the omission of the temporary assembly of a casing. A assembling method includes gaining measurement data on the configuration of a casing upper half part not fastened to a casing lower half part; gaining measurement data on the configuration ofthe casing lower half part in an open state in which the casing upper half part and a rotor are removed and in which a stationary part is mounted; comparing measurement data on the configuration of the casing upper half part and the casing lower half part with simulation data on the configuration of the casing upper half part and the casing lower half part previously obtained to select simulationdata closest to the measurement data on the configuration of the casing upper half part and the casing lower half part; calculating, based on the selected simulation data, a change amount of the configuration of the casing upper half part and the casing lower half part when the casing upper half part is fastened to the casing lower half part in the open state; and adjusting the installation position of the stationary part inside the casing taking into account the calculated change amount.

The invention discloses an assembly technique for a head sealing cover and a kettle of a stock solution crystallizer, which comprises the following steps of: according to the technique requirement, the head sealing cover is manufactured; according to the shape of the head sealing cover and the arrangement position of an adapter or a pipeline interface on the head sealing cover, an assembling supporting plate is manufactured; the head sealing cover is inversely arranged on the assembling supporting plate; the kettle is manufactured, lifted by a lifting device and inversely arranged on the headsealing cover; the position of the kettle is regulated; the contact site between the kettle and the head sealing cover is tightly jointed by depending on the self weight of the kettle; according to the technique requirement, the welding is carried out to cause the head sealing cover and the kettle to be connected into one body. In the assembly technique, the kettle is inversely arranged on the head sealing cover, and the self weight of the kettle is used for compressing the head sealing cover so that the kettle and the head sealing cover are tightly jointed, thus effectively reducing the crackbetween the kettle and the head sealing cover, being beneficial for the welding operation of the next step, preventing the deformation of the head sealing during welding, having more obvious protection effect on the head sealing cover, shortening the assembling working period and reducing the manufacture cost of equipment.

The invention discloses a hanging tool for a marine low-speed diesel engine piston assembly and a method using the hanging tool. The hanging tool comprises brackets, a special bolt for piston connection and a gas cylinder body connecting bolt, wherein when the piston assembly is hung, the lower end of the special bolt for piston connection is screwed into a piston bottom pin, and the upper end ofthe gas cylinder body connecting bolt is screwed into a lower bottom plate of the gas cylinder body. The using method comprises the following steps of: separately fastening the brackets to the two sides of the piston bottom pin and the lower side surface of the gas cylinder body; 2) dropping the piston assembly, and supporting the piston assembly through the two brackets; 3) lifting the gas cylinder body onto the upper plane of the rack to fold; 4) enabling an in-machine operator and an outside-the-machine operator to cooperate with each other, and enabling a cross head of a connecting rod tobear weight of the piston assembly through a turning gear; and 5) fixedly connecting the cross head of the connecting rod to the piston assembly, and dismounting the brackets. According to the hangingtool and the method using the hanging tool disclosed by the invention, the potential safety hazards, due to the fact that the piston assembly and the gas cylinder cover are repeatedly dismounted anda travelling crane is lifted by many times, of overhead operation are avoided, the assembly period is shortened, assembly cost is reduced, and assembly efficiency and assembly safety are improved.

The invention relates to a speed reducer alignment device, in particular to a speed reducer alignment device for mounting a speed reducer on a brick extruder. The speed reducer alignment device comprises a stand, a speed reduction motor and a transmission case, wherein the speed reduction motor and the transmission case are arranged on the stand through anchor bolt components; each anchor bolt component comprises a bolt, a nut, a screw seat and a stud; a threaded hole is formed in the center of each screw seat; the studs are screwed into the threaded holes of the screw seats in a threaded fit way; through holes are formed in the centers of the studs; the bolts are arranged in the through holes in a penetration way; cap parts of the bolts are arranged at the bottoms of the screw seats; the nuts are screwed to threaded sections of the bolts. According to the speed reducer alignment device, the speed reduction motor can be rapidly aligned with the transmission case, the speed reducer alignment device is high in regulation accuracy and efficiency, and the assembling period is shortened.

The invention provides a horizontal machining center. The horizontal machining center comprises a base, a main shaft head assembly and a stand column assembly. The stand column assembly is arranged on one side of the upper portion of the base. The stand column assembly is connected with the base in a sliding manner. The end, far away from the stand column assembly, of the upper portion of the base is provided with a workbench. The arrangement direction of the workbench is the same as the sliding direction of the stand column assembly. The main shaft head assembly is arranged on one side of the stand column assembly. The main shaft head assembly faces the workbench and is perpendicular to the X direction end face of the workbench. The main shaft head assembly is connected to the stand column assembly in a sliding manner. The main shaft head assembly comprises a main shaft box and a main shaft. The main shaft box is connected with the main shaft in the Z axis direction in a sliding manner. The main shaft can move in the X direction, the Y direction and the Z direction; and the workbench and the base are integrated, rigidity is good, a rotating table is arranged on the workbench, a large and heavy part can be completely machined though one time of clamping, and precision is high.

The invention discloses an automatic assembling machine for an emulsion pump.
