Cutter fixing device with heat dissipation function

Abstract

The invention discloses a cutter fixing device with a heat dissipation function, and relates to the technical field of cutter fixing. The cutter fixing device with the heat dissipation function comprises a fixed base, wherein a supporting assembly is fixed to the end face of the top of the fixed base through bolts; an elastic pressing structure is arranged on the supporting assembly; and a fastening bolt rod which penetrates through the supporting assembly and the elastic pressing structure and extends to the bottom of the elastic pressing structure is in threaded connection onto the supporting assembly. According to the cutter fixing device with the heat dissipation function provided by the invention, heat on a cutter can be directly transferred to a heat absorption assembly, and the heat absorption assembly transfers the heat to cooling water in the fixed base; and a fan arranged in the supporting assembly can accelerate air to be exhausted from a ventilation opening and enable the air to directly act on the cutter to dissipate heat of the cutter, so that heat dissipation of the cutter is further accelerated, the cutter fixing device has good ventilation and heat dissipation effects on the cutter, the phenomenon that the cutter is burnt due to the fact that heat generated by violent machining cannot be exhausted in time is avoided, and the service life of the cutter is prolonged.

Description

technical field [0001] The invention belongs to the technical field of tool fixing, in particular to a tool fixing device with heat dissipation function. Background technique [0002] In the process of machining mechanical parts, cutting machine tools are usually used to cut the parts, while the cutting tool on the machine tool is in direct contact with the parts and moves at a relatively high speed. Therefore, when cutting the parts, the tool has Higher temperature, in order to ensure the service life of the cutting tool and the quality of parts processing, the cutting fluid is usually sprayed on the tool being processed to cool down, so that the tool is within a reasonable temperature range. However, when the speed is too high and the machining process is too fast, the temperature rises sharply due to the small contact area between the tool and the parts, and the sprayed cutting fluid is blocked and cannot contact the tool in time, because the tool seat of the fixed tool c...

Problems solved by technology

[0003] The object of the present invention is to provide a tool fixing device with a heat dissipation function. By setting the clamping structure for the tool to directly contact the tool to cool down, the heat dissipation effect on the tool when the tool is processing parts is improved, and the existing tool is solved. The fixing seat does not have good heat dissipation performance, and the high temperature generated by the tool cannot be dissipated quickly, resulting in the problem that the tool is easily damaged and the service life of the tool is low
