A cooling and lubricating system for CNC lathe

Abstract

The object of the present invention is to provide a cooling and lubricating system for a CNC lathe to solve the problems in the prior art, including a liquid container, a first pipeline and a second pipeline, and the two ends of the first pipeline are respectively connected In the liquid container, the second pipeline is connected to the first pipeline through a heat exchange set, and the middle part of the first pipeline is provided with a first flow module connected to a tool holder for installing a turning tool, so The second pipeline is connected with a second flow module socketed with the spindle of the lathe, the heat exchange set is provided with an adjustment assembly for adjusting the interval between the first pipeline and the second pipeline, and the liquid container A first through-flow pump connected to the first pipeline, a filtering device and a temperature regulating device are arranged inside. Through the cooling and lubricating system of the CNC lathe, the overall structure can be simplified, the temperature control can be stable, and dynamic and precise control can be realized.

Description

technical field [0001] The invention relates to the technical field of numerically controlled lathe equipment, in particular to a cooling and lubricating system for a numerically controlled lathe. Background technique [0002] During the operation of the lathe, the rotation of the spindle drives the workpiece to rotate and contact the tool to achieve cutting. During the rotation of the main shaft, its rotational speed is high and heat generation is large. At the same time, the interaction force when the workpiece touches the cutting tool acts laterally on the spindle. Therefore, thermal deformation and bearing deformation during high-speed rotation make it difficult to maintain the ideal rotation state of the spindle, which in turn leads to shortened service life of the spindle or damage to the spindle. The existing bearing structure, lubricating structure and heat dissipation structure of the main shaft are complex and cannot cooperate with each other, resulting in too la...

AI Technical Summary

Problems solved by technology

The coolant sprayed by the external pipeline will be scattered everywhere, resulting in the need to clean up when changing the turning tool and picking and placing parts, and the work efficiency cannot be improved.

At the same time, the coolant sprayed from the outside to one point cannot provide heat absorption and uniformity to the turning tool as a whole, and the uneven heat distribution will further aggravate the vulnerability of the turning tool

[0003] In order to solve the above problems, various pipelines are generally used to provide them with cooling fluid, lubricating fluid, etc., which leads to complex pipeline setup and inconvenient maintenance of the overall lathe, and the separate cooling and lubrication of each place makes the overall control difficult and various The temperature fluctuation of parts is large, which is easy to cause problems such as interference, wear, and accuracy drop caused by uneven thermal deformation
