Problems solved by technology

[0005] However, due to the working characteristics of the drilling device, the drill bit will generate huge heat when it is working, which will cause certain interference to the drill bit and the workpiece. At present, there is often no direct and effective cooling method to achieve a good cooling effect.

Embodiment 1

[0044] see Figure 1-2 , a self-cooling drilling device for a numerical control machine tool, comprising a machine tool body 1, a drilling machine 2 is installed on the machine tool body 1, a self-cooling drill 3 is installed on the drilling machine 2, and the self-cooling drill 3 sequentially includes from top to bottom The base part 31, the cooling part 32 and the working part 33, the cooling part 32 is connected with a plurality of evenly distributed water baffles 5, the top of the base part 31 is connected with a supplementary bag, the supplementary bag includes an iron plate and a plurality of cooling particles, and A number of cooling particles are attached to the lower surface of the iron plate. The cooling particles are made of saltpeter powder and magnetic powder. In normal conditions, the cooling particles can be attached to the iron plate with weak magnetic force. When the balloon 4 is triggered to float to the top, the strong magnet Under the action of the magnetic...

Abstract

The invention discloses a self-cooling drilling device for a numerical control machine tool, and belongs to the technical field of drilling. By improving a self-cooling drill bit, cooling water is layered by virtue of a plurality of built-in water stop sheets, a triggering balloon is matched, on the basis of the characteristic that saltpeter is dissolved in water to absorb a large amount of heat,single-layer water is forced to condense into ice to achieve an efficient cooling effect, meanwhile, the triggering balloon is retained to sense the cooling effect in real time, an ice layer melts andopens a water stop sheet on the next layer when the cooling is insufficient, the triggering balloon can actively float to make contact with a supplementing bag to complete supplementing of the saltpeter, then the weight is increased, the triggering balloon sinks to be matched with the next layer of water stop sheet, saltpeter is released again, the process is repeated, the stable cooling effect can be achieved for a long time, the temperature is kept within the proper working temperature all the time, and the self-cooling drill bit and a workpiece are effectively protected.

Description

technical field [0001] The invention relates to the technical field of drilling, and more specifically relates to a self-cooling drilling device for a numerically controlled machine tool. Background technique [0002] CNC machine tool is the abbreviation of numerical control machine tool, which is an automatic machine tool equipped with a program control system. The control system can logically process programs with control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the numerical control device through the information carrier. After calculation and processing, various control signals are sent by the numerical control device to control the movement of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing. [0003] CNC machine tools solve complex, precise, small-batch, and multi-variety parts processing problems. It is a flexible, high-efficiency automatic ...
