Embodiment 1

[0026] Such as Figure 1-3 As shown, the present invention provides a machine tool, including a tool body 2 installed on a processing machine tool 1, a heat exchange unit disposed inside the tool body 2, and a heat exchange unit arranged on the processing machine tool 1 and exchanging with the heat exchange unit. A temperature control unit 3 connected to each other, the heat exchange unit includes a cooling circulation circuit 4 arranged inside the cutter body 2 and a heat exchange structure 5 arranged between the cooling circulation circuit 4 and the inner wall of the cutter body 2 . Specifically, the cooling medium enters the cooling circulation loop 4 after being temperature-controlled by the temperature control unit 3, and exchanges heat with the tool body 2 through the heat exchange structure 5, so as to take out the heat on the tool body 2 in time to achieve the effect of cooling, not only It avoids the contamination of the workpiece and the tool by the cooling medium, f...

Embodiment 2

[0035] Different from Embodiment 1, the cooling medium inflow conduit 42 and the cooling medium outflow conduit 43 are parallel structures. Preferably, the cooling medium inflow conduit 42 and the cooling medium outflow conduit 43 are arranged in pairs, that is, several pairs of the cooling medium inflow conduit 42 and the cooling medium outflow conduit 43 are arranged in parallel to perform heat exchange respectively.

[0036] Such as Figure 4 As shown, the center of the tool body 2 is provided with a core support structure 21, and the outer periphery of the core support structure 21 is provided with an annular gap 22, and the cooling medium inflow conduit 42 and the cooling medium outflow conduit 43 are arranged on the In the annular space 22 , each pair of the cooling medium inflow conduit 42 and the cooling medium outflow conduit 43 is distributed symmetrically with respect to the center of the core support structure 21 . After the cooling medium is subjected to constant...

Abstract

The invention discloses a machine tool cutter. The machine tool cutter comprises a cutter main body mounted on a machine tool, a heat exchange unit arranged in the cutter main body, and a temperaturecontrol unit arranged on the machine tool and communicating with the heat exchange unit; and the heat exchange unit comprises a cooling circulation loop arranged in the cutter main body, and a heat exchange structure arranged between the cooling circulation loop and the inner wall of the cutter main body. As the cooling circulation loop and the heat exchange structure are arranged in the cutter main body, the cooling effect is achieved by timely taking out heat in the cutter main body, the pollution to workpieces and the cutter by a cooling medium is prevented, and a closed-loop feedback modeis realized through online monitoring of workpiece machining to improve the workpiece machining precision; at the same time, the temperature of the cooling medium is precisely controlled through the temperature control unit, so that the temperature control precision of the cutter is greatly improved; and the machine tool cutter achieves enough rigidity to satisfy the precision demands in precise and ultraprecise machining.

Description

technical field [0001] The invention relates to the field of precision machining, in particular to a machine tool tool. Background technique [0002] In the process of machining, due to the friction between the tool and the workpiece, the temperature of the tool will continue to rise. For example, in the process of turning, the temperature of the tool may rise to 800 ° C, and the excessive temperature will cause damage to the tool and the workpiece. Artifacts have many adverse effects. For the tool, on the one hand, if the working temperature is high, it will accelerate the tool wear and seriously affect the tool life; on the other hand, the extremely high working temperature will deform the tool, which will affect the machining accuracy. The influence length of the tool is 10mm, the thermal expansion coefficient of the tool is 11ppm, and the working temperature of the tool changes by 16°C during the machining process (temperature change rate 16 / 800=2%), so the uncontrollab...
