Indexing mechanism is made up of dividing gear, index plate, the directed fixture of bent axle and fastening screw oil cylinder.Dividing gear end face is provided with index plate, and the directed fixture one side of bent axle is axially arranged on index plate; Index plate cylindrical structure has calibration latch groove, fastening screw hydraulic oil cylinder driving fastening screw, the directed fixture of bent axle is used for directed clamping bent axle.
The utility model adopts hydraulic-driven tooth bar positional cylinder piston arrives desired location after sender, again by hydraulic-driven index cylinder, thus drive tooth bar to engage with dividing gear and rotate, after dividing gear arrives setting corner, index plate locating slot after sender is inserted, tooth bar positional cylinder piston return sender, index cylinder return sender by hydraulic-driven fastening screw, complete calibration, the angle that dividing gear rotates regulates the stroke of index cylinder to realize by stop adjusting screw.
Operation principle of the present utility model is, this structure is made up of rack drives mechanism and indexing mechanism two parts, adopt hydraulic pressure as drive source, under the effect of certain pressure oil, positional cylinder piston rod drives index cylinder and tooth bar, tooth bar is made to reach the position of engaging with dividing gear, then index cylinder driving tooth bar engages with dividing gear and rotates, dividing gear is provided with index plate, index plate cylindrical structure there are the phase place according to crank-shaft link neck and the calibration latch groove that designs, gear face is provided with the directed fixture of bent axle by index plate, drive crankshaft rotating when dividing gear rotates thus complete calibration.
The beneficial effects of the utility model are, the utility model adopts hydraulic-driven tooth bar positional cylinder piston arrives desired location after sender, again by hydraulic-driven index cylinder, thus drive tooth bar to engage with dividing gear and rotate, after dividing gear arrives setting corner, index plate locating slot after sender is inserted by hydraulic-driven fastening screw, tooth bar positional cylinder piston return sender, index cylinder return sender, complete calibration, the angle that dividing gear rotates regulates the stroke of index cylinder to realize by stop adjusting screw.The utility model structure is simple, reliable, applied widely, calibration efficiency is high and indexing accuracy is high.
The utility model is applicable to Crankshaft Grinding automatic indexing.
