Hydraulic mechanical parts, due to their large size composition, weight, casting, forging, machining, assembly and other process conditions, can not be completely dependent on the precision work itself, so that processing must be done to ensure their own, but must go through the assembly process Adjust to achieve the accuracy of its goals.
Adjustment is based on the specific requirements of the operation, SKF bearing detection accuracy, while maintaining accuracy and stability will depend on the relevant pre-tightening force and lock means and measures to ensure. The industries used by hydraulic presses differ from each other because they use different precision requirements, and their work in manufacturing has also adopted different standards. The precision required for the production of different products in the same industry can be different. Therefore, it is divided into corresponding digital precision indicators in the working conditions and different levels of the same industry standards. The factory produces, in the press, the technical department tests the standard outline and prepares the test outline for accuracy, because the authorities issue a guidance document that provides the items, test methods and corresponding data parameters, installation and inspection adjustments and acceptance criteria. .
It generally includes the accuracy of the adjustment items that need to be implemented during the SKF bearing assembly process. If the height of the hydraulic table is high or low, the flatness of the table, the flatness of the vertical upper and lower beams, the working stroke of the master cylinder between the parallel tables, and the vertical and the column of the connecting beam are connected with the inner and outer nuts. The upper and lower limits of the surface contact rate. The process and results of SKF bearing precision adjustment and testing shall be approved by the full-time staff. After the peers are included in the scheduling production process, they are tested during the process of adjustment of the tools and molds designed by the professional staff. Omit the test framework and test work to adjust.
