Problems solved by technology

[0002] The hydraulic system is often used in medical, biological and some scientific research equipment. The early liquid system adopts a scattered arrangement of pipeline connections. This arrangement often leads to messy internal pipelines of the equipment, which is not conducive to production and manufacturing, and is also inconvenient for maintenance and troubleshooting. In addition, longer pipelines will cause waste of reagents, and some reagents are very expensive. Using integrated blocks in the liquid system is an important way to solve the above problems, but the liquid pipes used in medical and biological fields are generally very small. For example, 0.5mm, the conventional drilling process on metal blocks is almost unusable, so the processing technology of micro holes on integrated blocks is an important processing technology that restricts the miniaturization and modularization of my country's hydraulic system

Abstract

The invention relates to a low-pressure liquid circuit integrated block and its processing technology. The liquid circuit integrated block includes a lower base, an intermediate base and an upper base. There is half a flow channel groove, the middle layer substrate is bonded to the lower layer substrate and the upper layer substrate respectively, and the flow channel grooves that are mirror images of each other are bonded to form a sealed flow channel; the processing technology is: select the lower layer used to make the integrated block The base, the middle base and the upper base use CNC precision milling technology to mill out half of the runner grooves on the upper surface of the lower base, the front and back of the middle base, and the lower surface of the upper base. After being combined, a sealed flow channel is formed to form an integrated block; this processing technology avoids the problem that the tiny holes cannot be processed on the integrated block, provides a method for the processing of the low-pressure liquid circuit integrated block, and provides a solution for the miniaturization and modularization of the liquid circuit system design. made possible.
