A Clamping and Avoidance Mechanism for Expansion and Breakage of Connecting Rods

Abstract

The invention relates to a clamping and avoiding mechanism for connecting rod breaking, which includes a pressing component and a clamping component. A connecting seat is installed on the base, and the adjusting rod can vertically adjust the position relative to the connecting seat. The front end of the seat plate is provided with an elastic front clamping block hinged with the seat plate, and the front clamping block locks the large end of the connecting rod. The pressing assembly includes a cylinder hinge seat, a pressing cylinder, and a pressing head. A pressing block is arranged at the front end of the pressing head. The pressing block is perpendicular to the front end of the pressing head. When the piston rod of the pressing cylinder is stretched out, the pressing block moves down. The clamping assembly includes a V-shaped block, a movable seat, a spring seat, and a limit block. The round head rod is in contact with the bottom of the movable seat, and the spring seat and the limit block act together on the movable seat to keep the front clamping block horizontal. The manipulator presses the connecting rod between the V-shaped block and the front clamping block at the feeding station. The invention has a reasonable structure, and can press and rotate the V-shaped block in sequence when the connecting rod is tensioned, withdraws and raises it up, leaving a space for the connecting rod to avoid, and avoiding the impact on the clamp during the tensioning and breaking process.

Description

Technical field [0001] The present invention relates to the field of link processing and production, and in particular to a clamping, avoidance mechanism for connecting rods. Background technique [0002] The connecting rod group consists of a link body, a link head cover, a link small head bushing, a large head shaft and link bolt, and the link are important components of the engine. The company has designed a single-working turntable processing device, surrounded by a plurality of processing equipment, in the rotation process, laser modeling, and discharging, Install the components and other operations. Among them, the increase is a processing process of the link, and the connecting rod is characterized by the link body and the tile, and there is a very high precision between the two to ensure normal operation. Traditional links are multifaceted, and the processing process is: overall forging or casting, with split processing, milling, pulling, and milling of bonded surfaces, b...

Problems solved by technology

Before the breaking station, the connecting rod is installed in the fixture, and the expansion force is applied instantly, which will cause the fixture to be subject to a huge impact and be easily damaged.

At the same time, the blocking force of the clamp also affects the normal breaking of the big end of the connecting rod. Therefore, it is urgent to design a mechanism that can avoid when breaking and clamp the connecting rod body before and after breaking.
