Description

NOZZLE UNIT HAVING FIXING BLOCK FOR CNC LATHE}

The present invention relates to a fixed block for oneCNC lathe equipped with a nozzle unit, and more specifically, by providing a nozzle unit in which a nozzle tube and an injection hole are formed in a tool block for fixing a tool holder coupled with a tool tip in the oneCNC lathe, It can be easily supplied to the tool side, and relates to a fixed block for one CNC shelf equipped with a nozzle unit that can increase the space utilization of the space in which the tool block is installed in the one.

In general, when machining metal materials using CNC lathes, cutting oil is sprayed to reduce the heat of friction between the tool and the material and to cool the cutting edge of the tool. It is sprayed to make the noodles beautiful.

Conventionally, in order to supply cutting oil to a tool in a CNC lathe, as shown in FIG. 1, a spray hose 3a made of a bellows-type freely curved around the tool holder 1 in which the tool 2 is installed is included. It is used in such a manner that the cutting oil injector 3 is separately provided and the spray hose 3a is placed and sprayed at a site where a cutting operation is performed.

However, the coolant injection device 3 including the bellows-type injection hose 3a has a few characteristics in that the tool 2 is coupled to the tool holder 1 one-to-one and installed on the Y-axis base table 300 in the lathe. When the tool 2 is installed by the tool holder 1, the coolant spraying device 3 must also be installed one by one for each tool, and the installation space of the Y-axis base table 300 becomes complicated, and the bellows spraying hose ( When the cutting oil is sprayed through 3a), the cutting oil is not accurately sprayed on the tool 2 and the cutting part, thereby shortening the life of the tool 2 and increasing the defect rate of the product. The problem of having to replace the injection hose 3a frequently by blocking the inlet of 3a). In addition, also in the manufacturing of the machine has a problem that the machine manufacturing cost is also increased by separately installing the coolant injection device (3).

Therefore, the present invention improves the problems of the prior art, by having a nozzle unit formed with a nozzle tube and an injection hole configured to be used in combination with the tool holder in a multi-stage structure, the tool tip installed in the tool holder and It is an object of the present invention to provide a fixed block for OneCNC lathe equipped with a nozzle unit that can be easily supplied and sprayed to the cutting surface of the workpiece.

According to a feature of the present invention for achieving the above object, the present invention is a CNC shelf fixed block formed with a receiving portion for coupling a tool holder, it is installed in multiple stages with the tool holder in the receiving portion, the cutting oil supply pipe The insertion hole is formed is connected, the nozzle tube is formed to allow the cutting oil to pass through the insertion hole is communicated, the nozzle unit consisting of the injection hole formed to gradually narrow the predetermined interval inclined toward the outlet side by extending the nozzle tube It is characterized by the configuration.

In the CNC shelf fixed block provided with a nozzle unit according to the present invention is characterized in that the injection port of the nozzle unit is formed so that the spiral tapered.

According to the CNC shelf fixed block equipped with a nozzle unit according to the present invention, the tool tip and the workpiece installed in the tool holder through a nozzle unit that can be supplied to the cutting oil by supplying to the tool block with the tool holder Cutting oil is precisely and easily supplied to the machining surface, which reduces the defect rate of the product and extends the life of the tool, resulting in economical effects, and eliminating the need for a separate injection means around the tool block. The effect is to increase the utilization.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIGS. 2 to 4. On the other hand, in the drawings and the detailed description of the construction and operation that can be easily understood by those skilled in the art from the general CNC shelf fixed block 3 and omitted or omitted. In particular, in the drawings and detailed description of the drawings, detailed descriptions and illustrations of specific technical configurations and operations of elements not directly related to technical features of the present invention are omitted, and only the technical configurations related to the present invention are briefly shown or described. It was.

Figure 2 shows a separate perspective view showing a fixed block for one CNC shelf equipped with a nozzle unit according to the present invention, Figure 3 shows a combined perspective view showing a fixed block for one CNC shelf equipped with a nozzle unit according to the present invention, Figure 4 Figure 4 shows a cross-sectional view showing a state of use of the fixed block for the CCC shelf equipped with a nozzle unit according to the present invention.

The CNC shelf fixed block provided with the nozzle unit of the present invention, in the CNC shelf fixed block 100 formed with a receiving portion 101 for coupling the tool holder 20,

The receiving portion 101 is installed in the multi-stage with the tool holder 20, the insertion hole 11 is connected to the cutting oil supply pipe 40 is formed in the rear portion, and the cutting oil passes through the insertion hole 11 Nozzle tube 12 is formed so that the nozzle unit 12 is extended, the nozzle unit 10 consisting of the injection port 13 formed with a spiral taper (13a) is gradually narrowed while gradually inclining a predetermined interval toward the outlet side toward the outlet side ) Is characterized by the configuration.

The nozzle unit 10 is inserted into the fastening part 101 formed on one side of the fixed block 100 to have a multi-stage structure together with the tool holder 20, and is provided on the upper side of the fixed block 100. By fixing by the fixing bolt 102 can be easily assembled.

Looking at the operation of the present invention.

The present invention is configured by installing the nozzle unit 10 through which the nozzle tube 12 and the injection hole 13 are formed so as to have a multi-stage structure in the fixed block 100 together with the tool holder 20, the nozzle tube 12 of the The cutting oil supply pipe 40 is coupled to the insertion hole 11 formed at the rear portion by a connecting means such as the nipple 30 to supply the cutting oil. Therefore, the cutting oil supplied through the cutting oil supply pipe 40 passes through the nozzle pipe 12 of the nozzle unit 10 as a passage and is coupled to the tip of the tool holder 20 through the injection hole 13. The cutting oil is easily sprayed onto the machining surface of the workpiece. At this time, as the injection hole 13 formed by extending the nozzle tube 12 is gradually formed to narrow toward the outlet side, it is possible to supply pressure to the sprayed cutting oil and to accurately supply the cutting oil to the tool tip 21 or the processing surface of the workpiece. In addition, the inner surface of the injection hole 13 is formed to be a helical taper 13a so that the vortex phenomenon occurs due to the spiral formed on the inner surface of the injection hole during the pressure injection of the cutting oil, thereby widening the injection range. At the same time, the injection efficiency can be increased, so that cutting oil can be easily supplied to the tool tip 21 and the machining surface of the workpiece.

As described above, the one and one CNC shelf fixed block equipped with a nozzle unit according to an embodiment of the present invention is shown in accordance with the above description and drawings, but this is only an example and within the scope not departing from the technical spirit of the present invention. It will be understood by those skilled in the art that various changes and modifications are possible in the art.
