Definitions

  • the invention belongs to the class of machining methods, in particular to a method for grinding a crankshaft. Background technique
  • crankshaft is often used in mechanical transmission. Since the crankshaft has many gear positions that are not on the same axis, it must be clamped and grounded several times during machining, resulting in low grinding efficiency and difficult machining accuracy. Summary of the invention
  • the object of the present invention is to provide a crankshaft grinding processing method which is simple and reasonable, and can use the numerical control device to follow the different gear positions of the crankshaft.
  • a crankshaft grinding processing method characterized in that: a grinding wheel is mounted on a vertical rail, a vertical rail is mounted on a horizontal rail, a main gear of the crankshaft is mounted on a rotating shaft, and the horizontal rail, the vertical rail, and the rotating shaft are The CNC system is linked; the rotating shaft is first rotated, and the outer circle of the crankshaft main gear is ground by a grinding wheel; then the grinding wheel is moved to the eccentric gear, and the eccentric gear rotates with the rotating shaft, and the grinding wheel moves with the eccentric gear under the horizontal guide rail and the vertical guide rail, grinding By cutting the outer circle of the eccentric gear, the crankshaft can be ground.
  • the height of the center of the grinding wheel is always consistent with the height of the center of the gear shaft.
  • the grinding wheel is mounted on the horizontal rail and the vertical rail, and is controlled by the numerical control system together with the rotating shaft, and the center height of the grinding wheel is always consistent with the center height of the gear shaft to be ground, and the crankshaft is ground under the linkage of the numerical control system.
  • the outer circle of the main gear and the outer circle of the eccentric gear realize the grinding process of the crankshaft.
  • the method has high grinding efficiency and can improve the machining accuracy of the crankshaft.
  • Figure 1 is a schematic view of a processing method of the present invention.
  • Figure 2 is a schematic view of the crankshaft structure.
  • Figure 3 is a schematic view of grinding the eccentric gear at different positions of the grinding wheel.
  • a crankshaft grinding processing method is characterized in that: a grinding wheel 1 is mounted on a vertical rail 2, a vertical rail 2 is mounted on a horizontal rail 3, and a main gear 4 of the crankshaft is mounted in a On the rotating shaft, the horizontal rail 3, the vertical rail 2, and the rotating shaft are linked by the numerical control system; firstly rotate the rotating shaft, and grind the outer circle of the crankshaft main gear 4 with the grinding wheel 1; then move the grinding wheel 1 to the eccentric gear 5, the eccentric gear 5 With the rotation of the rotating shaft, the grinding wheel 1 moves with the eccentric gear 5 under the movement of the horizontal rail 3 and the vertical rail 2, and the outer circumference of the eccentric gear 5 is ground, and the crankshaft can be ground.
  • the height of the center of the grinding wheel 1 is always consistent with the center height of the geared shaft.
  • Fig. 3 it is assumed that the eccentric distance between the eccentric gear 5 and the main gear 4 is L, the diameter of the main gear is H, the diameter of the eccentric gear is W, the radius of the grinding wheel is R, and the center point of the rotating shaft is taken as the coordinate origin, to the level

Abstract

L'invention concerne un procédé de meulage pour un vilebrequin. Une meuleuse (1) est installée sur un rail de guidage vertical (2) ; le rail de guidage vertical est installé sur un rail de guidage horizontal (3) ; l'arbre principal (4) du vilebrequin est installé sur un arbre tournant ; les deux rails de guidage et l'arbre rotatif sont entraînés par un système de commande numérique. Le procédé comprend les étapes suivantes : utiliser la meuleuse pour meuler l'arbre principal ; déplacer la meuleuse jusqu'au décalage excentrique (5) ; conduire la meuleuse se déplaçant avec le décalage excentrique pour meuler le décalage excentrique. Selon l'invention, le centre de la meuleuse est maintenu à la même hauteur que le centre du décalage excentrique.
