Description

Clamping device for machining end face of cylindrical spring for hydraulic equipment Technical Field The invention relates to the technical field of spring production, in particular to a clamping device for machining a cylindrical spring end face for hydraulic equipment. Background The hydraulic equipment needs to use large-scale cylindrical springs, and the ends of the cylindrical springs need to be polished, so that planes are formed at the two ends of the cylindrical springs, and the cylindrical springs are convenient to attach to the surface of the equipment during equipment installation. When carrying out terminal surface processing to cylindrical spring, need carry out effective clamping to the spring, the clamping needs to pay attention to two problems, and the clamping is effective to support the spring at clamping in-process to carry out effective fixed after the extrusion, and another is to prevent that the spring from producing rotatoryly at the terminal surface in-process of polishing, current clamping equipment does not do two above-mentioned points in place, and can not carry out effective support to the spring when the clamping, is inconvenient for carrying out effective regulation to the spring that is supported, and causes spring rotational deformation easily in the course of working.
