Problems solved by technology

The current approach is: first, the balance of thermal deformation is considered in the mechanical structure design stage of the machine tool, but the problem cannot be solved fundamentally; secondly, the temperature rise of the machine tool is controlled by cooling, and the cooling system and Lubrication system, the former uses oily liquid to take away the heat generated by the cutting tool of the machine tool, and the latter uses lubricating oil to take away the heat generated by the transmission of the machine tool, and uses two oil coolers to directly reduce the temperature rise of the two systems that are equipped. Method Due to the error in the temperature control of the single refrigeration system by the oil cooler, it can only play a role in the temperature rise of the respective systems, and the temperature difference between the various parts (positions) of the machine tool still cannot be eliminated, so the machine tool still has the possibility of causing machining errors.

Embodiment Construction

[0009] Such as figure 1 As shown, the thermal deformation remote diagnosis and control device of the machine tool of the present invention is suitable for any machine tool for machining, except for the device including the cutting cooling circulation system 1 commonly equipped on existing machine tools and the cutting cooling circulation system 1 In addition to the oil cooler 2, a first thermal sensor 3 is also provided in the cutting area a of the machine tool. When the temperature of the machine tool is relatively stable but there is a temperature difference between the machine tool and the cutting area, the area b that will cause thermal deformation of the machine tool is provided The second thermal sensor 4, the first thermal sensor 3 and the second thermal sensor 4 realize remote communication with the control module 5 on the oil cooler 2. The first thermal sensor 3 and the second thermal sensor 4 transfer the collected temperature signals to the control module 5 on the oil c...

Abstract

A remote diagnosing and controlling apparatus for the thermal deformation of machine-tool is composed of a cooling circulation system for cutting, an oil cooler with a control module, the fist thermosensitive inductor in cutting region, and the second thermosensitive inductor in thermally deforming region. The temp difference between said two inductors can be used to control the oil cooler.

Description

Technical field [0001] The invention belongs to the technical field of machine tools, and specifically relates to a device for controlling thermal deformation of a machine tool. Background technique [0002] The machine tool inevitably has heating problems during the machining process. The heating will cause the local temperature of the machine tool to rise, and the heating of the parts (bits) of the machine tool is often inconsistent, resulting in a large temperature difference between the parts and the machine tool Deformation, resulting in a series of problems such as reduced machining accuracy, unstable mechanical actions, increased mechanical transmission errors, increased tool wear, poor surface processing quality of workpieces, deterioration of cooling and lubricating oil quality, and increased maintenance service costs. In order to ensure the machining accuracy of the machine tool, improve the stability of the machine tool and the quality of the processed products, for a ...
