Hidden type drill bit cooling device capable of saving water resources

Abstract

The invention provides a hidden type drill bit cooling device capable of saving water resources. The hidden type drill bit cooling device comprises a supporting mechanism, a cooling mechanism and a circulating mechanism; the bottom of the tail end of the supporting mechanism is fixedly connected with the circulating mechanism; the cooling mechanism is arranged in an inner cavity of the circulating mechanism; the supporting mechanism comprises a supporting rod; one end of the supporting rod is fixedly connected with a fixed table through a supporting table; the bottom of the fixed table is rotationally connected with a rotating lock through a rotating shaft; and the cooling mechanism comprises a heat conduction sleeve which is fixedly connected to the bottom of the rotating lock. According to the hidden type drill bit cooling device capable of saving the water resources, a special structure which does not block normal operation of a drill bit and senses the temperature of the drill bit to spray water in time is designed according to the conditions that a cooling device of an existing drilling machine blocks movement of a workpiece and continuously sprays cooling water; and therefore, the problems that normal operation of the drill bit is hindered due to the fact that a spray head is additionally arranged in the drilling process of a common drilling machine and water resources are greatly wasted due to continuous water spraying in the drilling process are effectively solved.

Description

technical field [0001] The invention relates to the technical field of drilling equipment, in particular to a water-saving hidden drill bit cooling device. Background technique [0002] When the drilling machine is drilling the workpiece, due to the high-speed rotation of the drill bit for a long time, the drill bit and the surface of the processed workpiece will rub against each other. Workpieces that are not resistant to high temperatures, such as plastics, will be deformed due to heat during processing. During processing, the area of ​​the drilled hole becomes larger, which greatly affects the accuracy of the drilling machine. [0003] Drilling machines on the market now generally use water-cooling devices to cool the drill bit, use the nozzle to spray water on the drill bit, let the cooling water flow through the surface of the drill bit to take away the heat on the drill bit, but because the drill bit needs to drill into the inside of the workpiece, it is necessary to ...
