Mounting fixture is used in cross head processing

Technical Field

The utility model belongs to the technical field of machining, specifically be a mounting fixture is used in cross head processing.

Background

The crosshead is a part connecting the piston and the connecting rod and has a guiding function. The compressors mostly adopt closed type crosshead of which the small end of the connecting rod is placed in the crosshead body, and the compressors adopt open type crosshead matched with a fork-shaped connecting rod. The connection type of the crosshead and the piston rod is divided into a threaded connection, a connector connection, a flange connection and the like. The threaded connection structure is simple, and the dead point clearance in the cylinder is easy to adjust. However, the piston needs to be rotated during adjustment, and when threads are cut on the crosshead body, the crosshead body is easy to wear after being disassembled and assembled for many times, and the precision requirement is not easy to guarantee. Therefore, the structure is commonly used for medium and small compressors. The structure that the two nuts are clamped and fixed is adopted instead of cutting threads on the crosshead body, and the structure can be used for large and medium-sized compressors. The connector and the flange are connected, so that the use is reliable, the adjustment is convenient, and the piston rod and the crosshead are easy to align. But the structure is complicated and heavy, and the compressor is mainly used for large compressors. The connection between the crosshead and the link is performed by a crosshead pin, and a jig is generally used when the crosshead is processed.

When the existing crosshead processing clamp is used, the crosshead is inconvenient to fix and often shakes.
