Embodiment 1

[0014] Embodiment 1: with reference to attached Figure 1-6 . A jig for milling two planes of an automobile connecting rod cover. One end surface of a central shaft 11 is a ball head, and the other end surface is a concave spherical surface. The lower part of the seat surface of the base 1 is in the shape of an inverted mountain. The base 1 is molded by mold casting, and the middle part of the base 1 has a shaft hole horizontally. Steel sleeves 13 are provided at both ends of the shaft hole, and a reinforcing steel sleeve 12 is provided between the two steel sleeves. The central axis 11 is located between the two steel sleeves 13 and the reinforcement steel Inside the sleeve 12, the ball head of the central shaft 11 is in contact with the right pressing plate 5, and the concave spherical surface is in contact with the ball head of the screw rod 9. The right pressing plate 5 has a concave spherical surface and matches the ball head of the central shaft 11. The screw 9 is scre...

Embodiment 2

[0015] Embodiment 2: On the basis of Embodiment 1, a quick clamping method for milling two-plane fixtures of automobile connecting rod covers, the base 1 is fixed on the machine tool used, and two workpieces to be processed are placed on the opening surface of the V-shaped block and In the cavity of the workpiece to be processed formed by the left pressing plate and the right pressing plate, then use a wrench to turn the screw 9, the screw 9 drives the central shaft 11 to move forward, the left pressing plate 8 moves backward, and the central shaft 11 moves forward to push the right pressing plate 5, forcing The left pressing plate 8 and the right pressing plate 5 press the workpiece for processing.

Abstract

The invention relates to a fixture for milling two planes of an automobile connecting rod cap, which can quickly position the automobile connecting rod cap. In the fixture, one end face of a center shaft is a ball head, and the other end face of the center shaft is a concave spherical surface; an axle hole is transversely formed in the center part of a base; two ends of the axle hole are providedwith steel bushings; a rib reinforced steel bushing is arranged between the two steel bushings; the center shaft is positioned in the two steel bushings and the rib reinforced steel bushing; the ballhead of the center shaft contacts a right pressing plate; the concave spherical surface contacts a screw ball head; a screw is screwed into a screw nut positioned in a left pressing plate; the left pressing plate and the right pressing plate are connected with the central part of two sides of the base by a lateral pressing plate and a straight pin respectively; a V-shaped block is fixed in the center of the base and divides the base into left and right relative moving parts; and two support blocks are positioned on the base at an opening side of the V-shaped block respectively. The fixture has the advantages of capacity of quickly and precisely positioning the automobile connecting rod cap and improving the machining efficiency by 150 percent, perfect machining precision, novel, unique and simple structural design, and high practicability.

Description

technical field [0001] The invention relates to a jig for milling two planes of an automobile connecting rod cover capable of rapidly positioning the automobile connecting rod cover, belonging to the field of manufacturing special fixtures for automobile parts.
