Abstract

The invention relates to a drilling system for a numerically-controlled machine tool spindle box and a heat dissipating method of the drilling system. The drilling system comprises a rack and a movingmechanism used for controlling the spindle box to move, and is characterized by further comprising a drilling device and a heat dissipating device, wherein the drilling device is mounted on the rack,controlled by a lifting module to rise and fall, and used for drilling holes in the spindle box; the heat dissipating device is mounted on the rack, and comprises a heat dissipating cavity, a heat dissipating body, at least one cooling cavity, a liquid injecting circulation port and a liquid discharging circulation port; the heat dissipating cavity is used for the movement of the output end of the drilling device; the heat dissipating body is provided with the heat dissipating cavity; the cooling cavity is arranged in the heat dissipating body; and the liquid injecting circulation port and the liquid discharging circulation port are arranged outside the heat dissipating body and communicate with the cooling cavity. The drilling system and the heat dissipating method have the beneficial effects that the use is stable and the precision is high.

Description

technical field [0001] The invention relates to the technical field of spindle box drilling, in particular to a drilling system for a spindle box of a numerically controlled machine tool and a heat dissipation method thereof. Background technique [0002] The spindle box is the most important component of the machine tool. It is mainly used to arrange the transmission parts and additional devices of the machine tool. Therefore, when the spindle box is processed, it is usually necessary to open holes to ensure its use; [0003] However, after the current drilling device (or system) for the main shaft drills the main shaft box, the drill bit will generate a lot of heat due to continuous work, so that the drill bit is in a high-temperature working state for a long time, which easily affects the service life of the drill bit. ; [0004] Not only that, but after the existing headstock is drilled, a large amount of iron filings will be adsorbed on the drill bit, so that the drill...
