Title
(EN) CONNECTING ROD FRACTURING FIXTURE
(FR) MACHINE DESTINEE A BRISER UNE BIELLE
Abstract
(EN) The rod cap fracturing machine (10) is for cracking a rod cap (68) along a rod cap cracking plane (P) that is intersected by connecting rod center line (110) at an acute angle. The machine includes a first mandrel portion (58) fixed to a frame (12) and a second mandrel portion (60) on a carriage (40). A rod cap clamp assembly (74) on the carriage clamps the rod cap to the second mandrel portion. First and second wrist pin clamps (116, 118) clamp the wrist pin end (106) of the rod body along a line (124) perpendicular to the rod center line and prevent pivotal movement of the rod body relative to the crankshaft bore axis (114). A crankshaft end clamp (128) clamps the rod body to the first mandrel half and prevents bending of the long arm (134) of the rod.
(FR) Machine (10) destinée à briser un chapeau (68) de tête de bielle dans un plan de rupture (P) qui est traversé à un angle aigu par la ligne centrale de bielle. Ladite machine comporte une première partie mandrin (58) fixée à un châssis (12) et une second partie mandrin (60) portée par un chariot (40). Un ensemble de serrage (74) de tête de bielle situé sur le chariot serre le chapeau de tête de bielle sur la seconde partie mandrin. Des première et seconde pinces (116, 188) serrent l'extrémité (106) axe de piston du corps de bielle le long d'une ligne (124) perpendiculaire à la ligne centrale de bielle et empêchent le mouvement de pivotement du corps de bielle par rapport à l'axe (114) de trou de vilebrequin. Une pince (128) côté extrémité de vilebrequin serre le corps de bielle sur la première moitié de mandrin et empêche la flexion du bras long (134) de la bielle.
