Description
Technical field
The present invention relates to crankshaft correcting device field, be specifically related to a kind of crankshaft correcting device.
Background technology
Bent axle in process of production, after fine grinding, adopts ionic nitriding mode to carry out intensive treatment to bent axle surface usually.In intensive treatment process, because the thermal stress in process is discharged in hot lower meeting, and the thermal stress that ion Plasma Nitriding Treatment produces, cause bent axle to occur bending and deformation.Particularly the axle journal position deformation comparison of bent axle is serious because the axle journal of bent axle is connected with connecting rod usually, therefore higher to the processing request of axle journal, axle journal in process because comparatively macrobending can be there is in cutting force.But prior art is all adopt manually to knock bent axle to the check and correction of bent axle, positions bent axle.But manually knock bent axle, the dynamics that very difficult control is knocked at every turn is consistent, therefore needs repeated multiple times knocking, inefficiency.
Summary of the invention
The technical problem to be solved in the present invention adopts to crankshaft correcting the defect that man efficiency is low for prior art, provides a kind of crankshaft correcting device, have the advantages that bent axle efficiency is high.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: Crankshaft says base device, comprise first piston cylinder, the second piston cylinder, first piston bar, two the second piston rods and two back-up blocks; First piston bar is positioned at first piston cylinder, and the second piston rod is positioned at the second piston cylinder, and the left end of first piston cylinder is fixedly connected with the sidewall of the second piston cylinder, and one end of the second piston rod is provided with first piston, and the other end and the back-up block of the second piston rod are hinged; Be provided with screwed hole and piston hole in first piston cylinder, screwed hole is communicated with piston hole and the aperture of screwed hole is greater than the aperture of piston hole, is provided with push broach groove between screwed hole and piston hole; Two the second pistons and the second piston cylinder form plunger shaft, and the sidewall of the second piston cylinder is provided with through hole, and the piston hole of first piston cylinder communicates with the plunger shaft of the sidewall of the second piston cylinder and the second piston cylinder; First piston bar is followed successively by push rod, threaded rod and chuck, and the diameter of push rod is less than the diameter of threaded rod, and chuck is prism.
Adopt the crankshaft correcting device in this programme, comprise first piston cylinder, the second piston cylinder, first piston bar, two the second piston rods and two back-up blocks; The axle journal of crank to bent axle that back-up block supports bent axle in crankshaft correcting process corrects.First piston bar moves and drives first piston to move, first piston moves the pressure in the T-shaped plunger shaft that can change and be formed by first piston, first piston cylinder, the second piston cylinder and two the second pistons, first piston extrudes the air in T-shaped plunger shaft, pressure in T-shaped plunger shaft is increased, forces two the second pistons to move.Be provided with screwed hole and piston hole in first piston cylinder, screwed hole is communicated with piston hole and the aperture of screwed hole is greater than the aperture of piston hole; Facilitate that first piston is accessible to be penetrated in the piston hole of first piston cylinder.Push broach groove is provided with between screwed hole and piston hole; Lathe tool withdrawing when facilitating thread mill drilling.First piston bar is followed successively by push rod, threaded rod and chuck, and the diameter of push rod is less than the diameter of threaded rod, and chuck is prism; Chuck is the convenient clamping of prism, and threaded rod is threaded with first piston cylinder, and chuck rotates and first piston is moved.
Operation principle of the present invention and beneficial effect are: the chuck clamping first piston bar with spanner, and rotate chuck first piston is moved, the pressure in the T-shaped plunger shaft that first piston, first piston cylinder, the second piston cylinder and two the second pistons are formed reduces and forms negative pressure and force two the second pistons mobile thus make two back-up blocks also mobile in the middle of the second piston cylinder in the middle of the second piston cylinder.Then crankshaft correcting device being placed in band corrects between two cranks of bent axle, then the chuck of first piston bar is rotated, first piston is moved to the direction near the second piston cylinder, pressure in T-shaped plunger shaft is increased, force two the second pistons to move to away from the direction in the middle of the second piston cylinder, thus two back-up blocks are also moved to away from the direction in the middle of the second piston cylinder.Finally make back-up block contact crank, continue rotary chuck and make back-up block apply power to crank, thus correct the camber of bent axle between two cranks.Realize the correction to bent axle.
Adopt crankshaft correcting device of the present invention to correct bent axle, the crank uniform force at the axle journal two ends of bent axle for crankshaft correcting relative to manually knocking as can be seen here, and it is high to correct efficiency.
Further, spring is provided with between described back-up block and the second piston cylinder.Spring helps out to back-up block, facilitates back-up block to be in level and corrects bent axle to crank.
Further, the sidewall of described second piston cylinder is provided with safety valve in place between two the second pistons.Avoid first piston, first piston cylinder, the second piston cylinder and two second piston formed T-shaped plunger shaft in pressure excessive generation detonation accident.
Further, the screw thread of the threaded rod in described first piston bar adopts multi start thread.Make the speed of first piston movement faster.
Further, the seamed edge round-corner transition of described back-up block.Avoid back-up block in the process of crankshaft correcting because of back-up block seamed edge scratch bent axle.
Accompanying drawing explanation
Structural representation when Fig. 1 is crankshaft correcting device correction bent axle of the present invention.
