Problems solved by technology
Since this type of machine tool is mostly used for high-speed machining of disc parts (such as automobile brake discs and wheel hubs made of aluminum alloy) in terms of technical indicators, it is not suitable for precision machining of large-diameter bearing rings forged from high-strength metal materials. The low-speed and high-torque requirements of turning have been unsatisfactory in the application of similar domestic enterprises, so this type of machine cannot meet the production needs of medium and large-sized bearing rings

Abstract
The invention discloses an inverted numerical control lathe for precisely processing a large-sized bearing ring. The inverted numerical control lathe comprises a lathe body and an upright post, wherein one side of the lathe body is provided with a horizontal guide rail; the other parallel side of the lathe body is provided with a fixed cutter saddle; the upright post is arranged on the horizontal guide rail of the lathe body; the upright post is provided with a vertical guide rail; a tool carriage is arranged on the vertical guide rail; a main shaft, a main shaft motor and a transmission gear box are arranged on the tool carriage; a clamp is arranged at the lower end of the main shaft; the tool carriage is driven to move vertically along the vertical guide rail by using an axis-Z motor arranged on the upright post; and the upright post is driven to move horizontally along the horizontal guide rail of the lathe body by using an axis-X motor arranged on the lathe body. In the lathe, one side of the lathe body is provided with an automatic workpiece feeding, discharging and transmitting device to form automatic connection of lathe turning procedures of the same type. The inverted numerical control lathe is suitable for precisely turning medium and large-sized bearing rings of which the diameters are 100-400 millimeters, and has the characteristics of high clamping accuracy, high automation degree and low energy consumption; and as proved by practice, the processing accuracy completely meets a requirement.
Description
technical field [0001] The invention belongs to the field of numerical control machine tools, in particular to an inverted numerical control lathe for precise machining of large-size bearing rings. Background technique [0002] With the continuous development of equipment manufacturing technology, the demand for bearings in all walks of life is increasing, and its technical requirements are also getting higher and higher, which makes the trend of general bearing specialization more and more obvious. For bearing products with high technical content, such as large-scale, precise, complex-structured bearings with functional combinations for the automotive industry, machine tool industry, railway industry, petrochemical machinery, textile machinery and metallurgical industries, there are currently many domestic It is not yet self-sufficient and needs to be imported in large quantities. [0003] In this context, the applicant and Changshu Institute of Technology have worked hard...
