A kind of electric machine tool coolant temperature automatic adjustment device

Abstract

The invention discloses an automatic adjusting device for the temperature of coolant of an electrical machine tool. The automatic adjusting device comprises a box body, a box cover, a water suction pump mechanism, a cooling water tank mechanism, a mercury temperature jacking rod mechanism, a linkage switch mechanism, a three-way pipe and various types of hoses, a first water outlet communicates with a water tank water inlet through the corresponding hose, a water tank water outlet communicates with a second water inlet (72) through the corresponding hose, a second water outlet communicates with a first water inlet through the corresponding hose, a three-way water outlet communicates with a water pump pumping opening through the corresponding hose, a water pump water outlet communicates with a coolant outlet of the machine tool through the corresponding hose, the box cover is provided with a reflux liquid inlet, and the reflux liquid inlet is connected with a coolant recovery tank of the machine tool through the corresponding hose. According to the automatic adjusting device, when the temperature of the coolant of the electrical machine tool is increased, a heat dissipating device can be automatically started for temperature decreasing, and thus the purposes of decreasing the temperature of the coolant, prolonging the service life of a cutter, ensuring the machining quality of workpieces, and protecting the machine tool are achieved.

Description

technical field [0001] The invention relates to the technical field of machine tool equipment, in particular to a device for automatically adjusting the temperature of the coolant of an electric machine tool. Background technique [0002] As one of the most commonly used processing tools, the machine tool needs to rub violently with the workpiece blank in daily use. Therefore, a large amount of heat will be generated during the processing. After the blank and the tool are heated, the service life of the tool will be shortened, and The accuracy of the workpiece is unstable, so the tool and the blank need to be cooled during the chip cutting process. [0003] However, in the process of actually using the machine tool, the coolant is cooling the high-temperature workpiece and tool, and the coolant is recycled, so it is easy to cause the overall temperature of the coolant to rise, resulting in the inability to properly cool the workpiece and tool. Cool down, thereby shortening ...
