Problems solved by technology

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

Abstract

The invention discloses a four-screw driving system of a numerically controlled milling and boring machine, which includes a turbine and an intermediate body located on the left side of the turbine. A compressor is fixedly connected to the left side of the intermediate body, and a compression chamber is arranged in the turbine. The right side of the compression chamber is provided with an exhaust bypass valve chamber, and the front and rear walls of the exhaust bypass valve chamber are provided with rotating shafts, and an exhaust connecting rod is fixed on the exhaust shaft. The upper end of the connecting rod is fixed with an exhaust valve cover, and the right end of the exhaust connecting rod is fixed with an exhaust slider; Supercharging effect, stable expansion ratio of the turbocharger, without manual intervention in the whole process, greatly improving the utilization efficiency of the high-temperature exhaust gas of the engine, and at the same time reducing the density of the gas sent into the engine inlet when the engine has signs of deflagration, It can greatly enhance the power of the four-screw drive system.

Description

technical field [0001] The invention relates to the field of industrial technology, in particular to a four-screw driving system of a numerically controlled 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 ...
