Modular multifunctional machine tools for comprehensive machining processes

Abstract

Modular multifunctional machine tools for integrated machining processes enable the combination of several units that can process the workpiece (P) clamped once in a coordinated manner with each other, so that there is no need for any repositioning of the workpiece. The functional machine tool includes: a headstock (30) capable of placing the workpiece (P) to be machined in the workspace (A) and enabling the rotation (CC1) of the workpiece around the main axis (ZZ1) during the different machining operations ; at least one working guide extending substantially parallel to the main axis (ZZ1) and supporting at least two working units (10, 11, 21, 21ˊ, 22, 23, 23ˊ, 24, 25, 26, 26ˊ), these work units can slide independently on the work unit guide (42), so that they can be arranged alternately and independently of each other in the work space (A), so that the workpiece to be processed (P ), or set outside of the workspace (A).

Description

technical field [0001] The invention relates to a modular multifunctional machine tool for integrated machining processes, of the type having at least two work units capable of carrying out two different machining processes on a single clamped workpiece. Background technique [0002] In the field of machining by machining, there is a particular need to have available a single machine tool capable of carrying out a series of different machining processes on the workpiece to be machined. [0003] As one can easily understand, in the process of producing mechanical workpieces that require different machining processes, such as turning, gear cutting and other types of milling, the step of positioning the individual workpieces on the machine tool for a specific machining process takes considerable effort. time. Therefore, using different machine tools to carry out continuous processing on a single workpiece will take a long time, thereby greatly reducing productivity. [0004] ...

AI Technical Summary

Problems solved by technology

[0012] In this case, neither the modularity of the machine tool is provided nor the simultaneous use of several work cells on the workpiece is allowed

Furthermore, the movement of the assembly formed by these two units involves great difficulties, the assembly has non-standard characteristics as an element, which is large in size and heavy in weight

[0013] Furthermore, in general, in these multifunctional machine tools described above, as well as in other types of machine tools, such as those described in WO2006 / 106317, EP1574273, EP1726387, EP1190792 and US5,127,140, ​​it is not possible to obtain The impossibility of using two separate machine tools to obtain comparable working characteristics is that these working characteristics require suitable multifunctional work cells which, due to their large size, weight and technical characteristics, cannot Cannot achieve the same characteristics as traditional machine tools

[0014] Another problem associated with the above-mentioned machine tools, or in any case known from the above-listed patents, is that it is impossible to obtain complex workpieces that simultaneously require machining processes such as turning, hobbing and thread milling, none of the above-mentioned machine tools can clamp Turning, hobbing and thread milling operations on mechanical components on tight workpieces
