Ram component on processing machine tool

Abstract

The invention discloses a ram component on a processing machine tool. The ram component comprises a ram, a ram base, a jacket, a main shaft and a rotary driving mechanism, wherein the ram and the ram base are connected in a sliding fit manner, and the jacket is arranged at one end of the ram. As the ram adopts the thermal symmetrical structure of an axially hollow cylinder, the influence of thermal deformation on the processing precision of the machine tool can be reduced. The rotary driving mechanism directly drives the main shaft to rotate, so that the traditional mode that the main shaft is driven mainly by an external motor through a speed reduction box can be changed, and further the processing precision of the machine tool can be improved.

Description

technical field [0001] The invention relates to the technical field of machine tool manufacturing, in particular to a ram component on a machine tool. Background technique [0002] With the development of the economy in recent years, the machinery manufacturing industry has also developed rapidly. Most industries have higher and higher requirements for the accuracy of key components, which requires some processing machine tools to have better processing accuracy. The ram is a key part of the processing machine tool. At present, the ram on the processing machine tool has the following defects: (1) The structure is a square ram, which is not a thermally symmetrical structure from the perspective of thermal deformation, which makes The thermal deformation of the ram has an increased influence on the machining accuracy of the machine tool; (2) The main shaft in the ram is driven by an external motor through a reduction box to rotate. This traditional mechanical transmission ...

The ram is a key part of the processing machine tool. At present, the ram on the processing machine tool has the following defects: (1) The structure is a square ram, which is not a thermally symmetrical structure from the perspective of thermal deformation, which makes The thermal deformation of the ram has an increased influence on the machining accuracy of the machine tool; (2) The main shaft in the ram is driven by an external motor through a reduction box to rotate. This traditional mechanical transmission method will also affect the machining accuracy of the machine tool. (3) Since the ram is equipped with a motor and a reduction box, the center of the ram component deviates from the geometric center of the ram, which in turn increases the thermal-structural coupling deformation of the ram when the machine tool is working

These defects will affect the positioning accuracy of the tool, thereby reducing the accuracy of the processed product
