Four-lead screw driving system of numerical control milling-boring machine

Abstract

The invention discloses a four-lead screw driving system of a numerical control milling-boring machine, which comprises a turbomachine and an intermediate located on the left side of the turbomachine, wherein a pressure fan is fixedly connected with the left side of the intermediate; the turbomachine is internally provided with a compression chamber; an exhaust by-pass valve cavity is arranged on the right side of the compression chamber; a rotating shaft is rotationally arranged in a front wall body and a rear wall body of the exhaust by-pass valve cavity; an exhaust connecting rod is fixedly arranged on the exhaust rotating shaft; an exhaust valve cap is fixedly arranged at the upper end of the exhaust connecting rod; and an exhaust slide block is fixedly arranged at the right end of the exhaust connecting rod. The four-lead screw driving system is simple in structure, low in cost and simple and convenient to use and can achieve an identical supercharge effect for an engine in a high-speed state and a low-speed state; an expansion ratio of a turbocharger is stabilized; manual intervention is not required in a whole process; the utilization efficiency of high-temperature tail gas of the engine is greatly improved; at the same time, the density of gas delivered into an engine intake can be reduced when the engine has a detonation sign; and the power of the four-lead screw driving system can be greatly enhanced.

Description

technical field [0001] The invention relates to the field of industrial technology, in particular to a four-screw drive system around the resin of a CNC milling and boring machine. Background technique [0002] With the continuous development of industrial technology, four-screw drive is widely used as the most important drive system on CNC milling and boring machines. The four-screw drive system generally uses turbocharging to make the engine run at high speed, so as to perform high-speed drive. However, the traditional turbocharger has no obvious turbocharging effect when the engine is running at low speed, and the transient response characteristics are poor. Moreover, due to the exhaust gas of the engine and the ultra-high speed of the blade wheel shaft, the compressor will generate very high pressure when the air is compressed. Temperature, and high temperature is more serious to the loss of parts. Contents of the invention [0003] Aiming at the deficiencies of the ...
