A drill jig for processing steam balance hole of steam turbine rotor
ActiveCN121847847BImprove machining accuracyGood processing consistencyDrilling/boring measurement devicesBoring/drilling machinesImpellerSet screw
The application belongs to the technical field of steam turbine rotor processing, in particular to a drill jig for steam turbine rotor steam balance hole processing, which comprises a drill jig body, a bushing, a quick-change drill sleeve, a cylindrical pin and a set screw; the drill jig body is provided with a rectangular groove in the thickness direction; both sides of the bottom of the drill jig body are provided with through holes; the bushing is fixedly connected to the inside of one side of the through hole; the inside of the bushing is provided with the quick-change drill sleeve. The drill jig body with a "door" type structure is matched with the rectangular groove, which can quickly realize the preliminary positioning of the drill jig at the edge of the impeller, the radially limiting of the outer circle of the impeller is matched with the symmetrical distribution of the cylindrical pin, the center of the quick-change drill sleeve is accurately aligned with the positioning line, and the hole position deviation problem caused by the positioning deviation in the traditional processing is avoided; at the same time, the set screw at the bottom is stably pressed against the surface of the impeller spoke through the threaded connection, so that the drill jig can remain stable during the drilling process and prevent displacement caused by vibration.

Shaping and cutting device for longya lily instant noodle production
ActiveCN224169923UEasy to cutEasy to scrapeMetal working apparatusPressesElectric machineryInstant noodle
The utility model discloses a shaping and cutting device for longya lily instant noodle production, and relates to the field of instant noodle production. Under the action of the cutting mechanism, instant noodles are cut, meanwhile, the instant noodles are prevented from being adhered to the cutting knife, operation of the conveying belt is controlled, and the instant noodles are conveyed, at the moment, operation of the motor is controlled, the output end of the motor drives the lead screw to rotate, the lead screw drives the limiting plate to move, and therefore the movable plate is driven to move; the moving plate drives the two telescopic cylinders and the four connecting rods to move at the same time, at the moment, the telescopic cylinders are controlled to operate, the telescopic cylinders move the cutting knife downwards, at the moment, the moving speed of the limiting plate is the same as the transmission speed of the conveying belt, and the cutting knife cuts instant noodles; the instant noodle cutting device has the function of conveniently cutting the instant noodles, and the instant noodles added with lilium brownii are prevented from being adhered to the cutting knife in the cutting process.

Multi-flame-port longitudinal combustion device for quartz fiber material processing
ActiveCN224188601UImprove combustion efficiencyHigh practical valueIndirect carbon-dioxide mitigationGaseous fuel burnerMaterials processingScrew thread
According to the technical scheme, the multi-flame-port longitudinal combustion device for quartz fiber material processing comprises a box body, a two-way lead screw is arranged in the box body, a fixed block is rotationally arranged in the middle of the two-way lead screw, a movable block is arranged on the two-way lead screw in a mirror image thread mode, a threaded rod is arranged in the movable block, and the threaded rod is arranged in the box body. A limiting block is rotationally arranged at one end of the threaded rod, a threaded block is arranged on the threaded rod in a threaded mode, fixing plates used for installing a spray head are fixed to one end of the limiting block, one end of the threaded block and one end of the fixing block, and a combustion mechanism is arranged on the box and connected with the spray head through a hose. The two-way lead screw rotates to drive the two moving blocks to move reversely so as to adjust the distance between the spray head on the limiting block and the spray head on the fixed block, and the threaded rod rotates to drive the threaded block to move so as to adjust the distance between the spray head on the threaded block and the spray head on the limiting block. And therefore, the distance between two adjacent nozzles in the vertical direction is equal.
