Inverted digital control lathe for precise-finishing middle, large-specification bearing ring

Abstract

The invention discloses an inverted type numerical control lathe for accurately processing medium and large-scale bearing rings, which comprises a lathe bed and an upright post. One side of the lathe bed is provided with a horizontal guide rail, the other side of the horizontal guide rail is provided with an immovable support, the horizontal guide rail of the lathe bed is provided with the upright post, a vertical guide rail is arranged on the upright post, and the vertical guide rail is provided with a planker, and a main shaft, a main shaft motor and a transmission gear box are arranged on the planker; and the lower end of the main shaft is provided with a clamp, the planker is driven by a Z-axis motor arranged on the upright post to move vertically along the vertical guide rail, and the upright post is driven by an X-axis motor arranged on the lathe bed to move horizontally along the horizontal guide rail of the lathe bed. One side of the lathe bed of the lathe is provided with a device for automatically feeding, discharging and conveying work pieces to form automatic connection of turning processes of parallel lathes. The numerical control lathe is suitable for accurate turning of the medium and large-scale bearing rings with diameters of 100 to 400 millimeters, has the characteristics of good clamping accuracy, high degree of automation and low energy consumption, and fully meets requirements on processing accuracy proved by practice.

Description

Technical field: [0001] The invention relates to the field of numerically controlled machine tools, in particular to an inverted numerically controlled lathe specially used for precision machining medium and large-sized 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 In...

AI Technical Summary

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 hubs made of aluminum alloy materials) in terms of technical indicators, it is not suitable for precision turning of large-diameter bearing rings forged from high-strength metal materials. low-speed and high-torque requirements, and it has not been ideally reflected in the application of similar domestic enterprises, so this type of model cannot meet the production needs of medium and large-sized bearing rings
