Due to the large size and heavy weight of its components, and limited by various process conditions such as casting, forging, cutting and assembly, the working accuracy of the hydraulic press itself cannot be completely guaranteed by the machining itself, but must be adjusted in the assembly process to achieve its accuracy indicators.
The adjustment is carried out according to the specific Accuracy Detection requirements of INA Bearing accuracy detection, and the maintenance and stability of accuracy depend on the relevant pre tightening and anti loosening means and measures.
The hydraulic press used in all walks of life has different Accuracy Detection requirements for its working accuracy due to its different uses, and different industry standards are also used in production and manufacturing. In the same industry, due to Accuracy Detection different products, the required accuracy can not be consistent.
Therefore, in the same industry standard, it is divided into several levels according to different working conditions, corresponding to each accuracy index. During factory production, the technical department shall prepare the inspection outline and commissioning outline according to the accuracy standard of the production press,
and issue them to relevant departments as guiding documents, which specify the detection methods and corresponding data of relevant items and parameters as the Accuracy Detection standards for installation, adjustment, inspection and acceptance.
For example, in the hydraulic press, the levelness of the Accuracy Detection workbench, the deviation of column spacing, the flatness of the workbench and movable workbench, the perpendicularity of the column and its connected upper and lower beams, the parallelism between the worktables,
the perpendicularity of the main oil cylinder and the workbench within the working stroke, the contact Accuracy Detection rate of the inner and outer nut joint surface between the column and the upper and lower beams, etc.
The process and results of INA Bearing accuracy adjustment and testing can be passed only after being approved and signed by full-time personnel.
The tools and tooling required in the process of detection and adjustment are designed by the corresponding professional process personnel during production and programmed into the production process according to the plan. Inspection outline and inspection adjustment operation are omitted.
