Pipeline pump abdominal cavity machining method

Abstract

The invention discloses a pipeline pump abdominal cavity machining method and relates to the technical field of turbine machinery machining technique design. The pipeline pump abdominal cavity machining method is used for rapidly machining a pipeline pump abdominal cavity structure and comprises the steps that equal-height shim plates are arranged on a plano milling machine, and a pump body and apump cover are placed on the shim plates in the mode that the association planes are upward correspondingly; the pump body and the pump cover are compactly cushioned through the shim plates on the pressing plate clamping position and then clamped; the end faces of the pump body and the pump cover which are clamped are subjected to coarse machining through an end face milling tool program; the endface of an abdominal cavity of the pump body and an abdominal cavity spigot of the pump body are subjected to semi finish machining through a lengthened milling tool plate; and through a long millingtool plate, the abdominal cavity spigot of the pump body and the two end faces of the abdominal cavity are subjected to finish milling. By adopting the pipeline pump abdominal cavity machining method,overall machining of a pipeline pump product is developed into split machining, simple and rapid effects are achieved, the time and labor are saved, the blank of abdominal cavity split machining in the pump industry is filled up, a traditional machining mode is broken through, and the high popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of turbomachinery processing technology design, in particular to a method for processing the abdominal cavity of a pipeline pump. Background technique [0002] The method of processing the abdominal cavity of pumps in my country generally follows the following steps: dismantle the pump cover, enter the abdominal cavity through the bearing hole, install the boring tool, set the tool according to the part to be processed, test cutting, retract the tool and measure, install the pump cover , After the overall processing, the pump cover is disassembled for measurement, and the above steps are repeated until the processing is qualified. However, the pipeline pump is a new type of pump designed and developed by using foreign technology. It consists of two parts: the pump body and the pump cover. The minimum size of the inner hole of the side bearing area 3 is Φ160, the size of the sealing area 2 is Φ380, the abdomi...

Problems solved by technology

Due to the particularity of the structure, the abdominal cavity is a narrow space. According to the previous processing method and the limitation of equipment capacity, the abdominal cavity processing cannot be completed at all. At the same time, various methods are used for experimental processing. It is not that the processing time is too long and the construction period cannot be met. The requirement is too much damage to the equipment
