Description

Technical Field

[0001] The invention relates to the technical field of spiral bevel gear processing, in particular to a numerically controlled spiral bevel gear grinding machine. Background Art

[0002] In the field of spiral bevel gear processing, higher requirements are placed on the performance and efficiency of gear processing equipment. Traditional spiral bevel gear grinding machines have gradually exposed many problems in practical applications and can no longer meet the needs of modern industrial production.

[0003] On the one hand, the grinding operation of traditional gear grinding machines is often to grind a single gear one by one, and then carry out subsequent cleaning and other work after grinding. This method leads to low efficiency and greatly prolongs the processing cycle of spiral bevel gears, which is not conducive to enterprises to improve production efficiency and reduce production costs. In today's increasingly fierce market competition, it seriously affects the economic benefits of enterprises and the timely completion of production plans.

[0004] On the other hand, traditional gear grinding machines have obvious deficiencies in energy utilization and environmental protection. In the grinding process, the use of energy lacks systematicity and efficiency, resulting in a large amount of energy waste. For example, the dust removal and cooling systems in traditional equipment often operate independently and lack a collaborative working mechanism, resulting in large energy losses during transmission and conversion. At the same time, there is no perfect water circulation system, and water recycling cannot be achieved. Moreover, the dust removal function of traditional equipment is not perfect, and the dust and impurities generated during the grinding process will be dispersed in the workshop in large quantities, which not only pollutes the working environment but also endangers the health of operators.

[0005] In order to solve these problems, promote the progress of my country's arc bevel gear processing technology, and meet the urgent demand for high-performance, high-efficiency, energy-saving and environmentally friendly gear processing equipment, the present invention provides a new type of CNC arc bevel gear grinding machine, which improves grinding efficiency and ensures grinding accuracy while achieving efficient use of energy, recycling of water resources and friendly protection of the environment, providing strong technical support for the development of China's manufacturing industry.
