The invention relates to the technical field of valve grinding, and discloses a high-precision machine tool for valve grinding maintenance, which comprises a machine tool main body, a grinding assembly for valve grinding is arranged on the machine tool main body, and a liquid spraying assembly for improving the valve grinding effect is arranged on the machine tool main body. The machine tool body is provided with a collecting assembly used for collecting waste liquid, and the machine tool body is provided with a detecting assembly used for detecting the grinding face of the grinding wheel. Through the clamping and positioning process of a fixed clamping plate on a valve, rust removal liquid in a rust removal storage box is sprayed on the surface of the valve, then the rust removal liquid can soften and remove part of a rust layer, the rust layer is easier to remove in the grinding process, meanwhile, through the arrangement of a fixed groove plate, spraying of the rust removal liquid is quantitative spraying, and the rust removal efficiency is improved. In addition, in the process that the grinding wheel body moves downwards to grind the valve, the liquid sprayed on the surface of the valve can be switched into cooling liquid by switching rotation of the spherical shell.

The invention discloses a service data processing method and device, equipment, a medium and a product, relates to the technical field of data processing, and discloses a service data processing method which comprises the following steps: receiving a discount application message input externally, and determining and matching general parameters of the message with historical parameters in a cache; and if not, triggering the asynchronous task to call the peripheral system to perform parameter check, updating the check result to the first message table, and storing the general parameters to the cache. And analyzing and clearing the discount application message, storing discount application information in a first message table, performing real-time and asynchronous check on the information, updating a check result to the first message table, and generating a clearing message. Based on the liquidation message, triggering an asynchronous liquidation task, and calling a peripheral system to execute liquidation processing; if clearing fails, an asynchronous retry mechanism is triggered for processing. According to the invention, the business data processing efficiency is improved.

The application belongs to the technical field of computer software data processing, and particularly relates to a public employment service standardization processing method based on a work flow configuration. The method acquires public employment service matter configuration data and standard data elements, splits the matter configuration data into multiple handling nodes, and binds input data elements, output data elements, trigger conditions, pre-depending conditions and mutual exclusion conditions for the handling nodes; generates a matter constraint graph according to the handling nodes, the standard data elements and the binding relationship, and performs topology, repeated collection, condition coverage and rule reference consistency checking on the matter constraint graph; after the checking, compiles the matter constraint graph into a work flow description file containing node execution sequences, field mapping relationships and rule indexes, and creates a standardization processing process instance according to the work flow description file. The application can locate configuration defects before the process is published, reduce process running interruption and field mapping errors, and improve the consistency and traceability of the public employment service matter configuration.

The application discloses a solution method and device for direction perception disorder caused by rotating a mirror, and solves the problem that it is difficult to determine the adjacent tissue structure outside the part after endoscopic examination is rotated in similar upper gastrointestinal tract wall lesions. The application comprises the following steps: acquiring the pose information of an endoscope in an electromagnetic navigation system of a lumen target position and corresponding lumen image as a reference pose; acquiring the trajectory pose of the endoscope after adjusting the field of view in the electromagnetic navigation system and corresponding lumen image, and determining the Euler angle of each trajectory point according to the trajectory pose; acquiring the trajectory pose of the endoscope after adjusting the field of view in the electromagnetic navigation system and corresponding lumen image, and determining the Euler angle of each trajectory point according to the trajectory pose; and reconstructing the lumen and the adjacent tissue according to the lumen image three-dimensionally, and obtaining the rotated lumen and the adjacent tissue according to the rotating angle and the corresponding lumen image. Through the application, the adjacent tissue outside the endoscope can be clearly known after the endoscope is rotated to the best field of view.
