The machining hydraulic fixture comprises a rectangular fixture platform and a support base, wherein a left connecting circular disc and a right connecting circular disc are fixedly mounted on the left side and the right side of the rectangular fixture platform respectively through bolts; a core shaft is mounted between the left connecting circular disc and the support base; a rotating input shaft is mounted on the right connecting circular disc; a left upper bearing cover machining clamping position and a right upper bearing cover machining clamping position are arranged on the rectangular fixture platform; the left upper bearing cover machining clamping position comprises a first stopping block member, a second stopping block member, a first locating supporting part, a second locating supporting part, a first compressing device, a second compressing device, a first limiting member and a second limiting member which are mounted on the rectangular fixture platform; cutter insertion holes are further formed in the rectangular fixture platform at the left upper bearing cover machining clamping position; the right upper bearing cover machining clamping position comprises a third locating supporting part, a fourth locating supporting part, a fifth locating supporting part, a fourth compressing device and a fifth compressing device which are mounted on the rectangular fixture platform. According to the machining hydraulic fixture for the upper bearing cover of the automobile engine, the upper bearing cover billet can be clamped at a time, the surface and hole machining of the upper bearing cover billet can be fully completed, the clamping and installing is convenient, and the machining efficiency is high.

Description

technical field [0001] The invention relates to a tooling fixture used for machining mechanical parts, in particular to a hydraulic fixture for machining the upper cover of an automobile engine bearing. Background technique [0002] The upper cover of the automobile engine bearing has a top mounting surface and a bottom reference surface. There are positioning holes on both ends of the mounting surface. The inner side of the positioning hole has a semicircular groove. The groove is used to cooperate with the camshaft. It has an oblique hole, a mounting hole and a reference hole in the approximate middle of the mounting surface, and a bolt mounting hole on one side of the upper cover of the automobile engine bearing. [0003] When preparing the upper cover of the automobile engine bearing, the die-casting blank of the upper cover of the automobile engine bearing is taken, and the mounting surface, the positioning hole on the mounting surface, the groove, the inclined hole in ...
