Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model relates to a deep hole processing combined joint applied to an external cooling, internal cooling and numerical control boring and milling machine, as shown in figure 1 and figure 2, the combined joint comprises a three-way joint 3, three interfaces of the three-way joint 3 are respectively interface a, interface b and interface c, interface a and interface b are positioned on the same straight line and are communicated, interface a is sequentially connected with a conversion joint a2 and a quick-connect joint 1, interface b is connected with a connecting joint 5, an air guide connecting pipe 6 is arranged in the three-way joint 3, the outer wall of the air guide connecting pipe 6 is not contacted with the inner wall of the three-way joint 3, one end of the air guide connecting pipe 6 is connected with a conversion joint a2, the other end of the air guide connecting pipe 6 extends into the connecting joint 5, the gap between the outer wall of the part of the air guide connecting pipe 6 extending into the connecting joint 5 and the inner wall of the connecting joint 5 is not less than 2mm, interface c is sequentially, the sealing washer 7 is positioned between the inner wall of the three-way joint 3 and the outer wall of the air guide connecting pipe 6, and the inner side wall and the outer side wall of the sealing washer 7 are respectively attached to the outer wall of the air guide connecting pipe 6 and the inner wall of the three-way joint 3.
The utility model relates to a be applied to deep-hole machining combination joint's of cold numerical control boring and milling machine in outer cold-turning main parts effect specifically as follows:
the adapter a2 presses the end face of the air guiding adapter 6 and the sealing washer 7, so that the sealing washer 7 performs a sealing function.
The diameter of the air guide connecting pipe 6 is smaller than the bore diameter of the inner cavity of the three-way joint 3, so that the cooling liquid can smoothly flow into the inner cavity of the three-way joint 3.
The adapter 4 ensures that a relatively low pressure cavity is formed in the adapter 4, reducing the pressure of the coolant flowing into the inner cavity of the three-way joint 3.
The utility model relates to a be applied to deep hole processing combination joint's of cold numerical control boring and milling machine working principle in outer cold turn specifically as follows:
the quick connector a2 is connected with a high-pressure hose, the adapter 4 is connected with a coolant outlet of an external-cooling-to-internal-cooling numerical control boring and milling machine tool system through a hose, and the connector 5 is connected with an external-cooling-to-internal-cooling interface of an external-cooling-to-internal-cooling numerical control boring and milling machine tool.
High-pressure gas flows through the quick connector a2, the quick connector 1 and the air guide connecting pipe 6 through a high-pressure hose and flows out of the air guide connecting pipe 6, a low-pressure cavity is formed between the three-way connector 3 and the air guide connecting pipe 6 due to the flowing of the high-pressure gas, so that cooling liquid can flow into the three-way cavity from the connector of the three-way connector 3 without too high pressure (the pressure of a cooling system equipped by a common machine tool is enough) through the connecting connector 5 and can enter the three-way cavity, the cooling liquid enters a flow channel of the cutter body through the connecting connector 5 along with the high-pressure gas, the high-pressure gas mixed with the cooling liquid is released at the outlet of the cutter, and the cooling liquid is sprayed on the machining cutter edge in a mist form, so that the cutter edge of.
Meanwhile, high-pressure gas mixed with cooling liquid continuously enters the drilled hole from the flow channel of the cutter, so that the pressure in the hole is increased, and the aerial fog flows out from the front end of the drill bit through the chip groove. Because the pressure is high, when the aerial fog flows out, the iron chips generated in the processing can be taken out, and a large amount of iron chips cannot be accumulated in the chip grooves. Because the iron chips contain a large amount of cutting heat, when the iron chips are taken out, the heat in the iron chips is prevented from being transferred to the cutter body. Therefore the utility model relates to a be applied to deep hole processing combination joint of cold numerical control boring and milling machine in outer cold-turning can realize deep hole processing.
In the high-speed processing process of deep hole, if the iron fillings can not be cleared away in time, the danger of clamping bits and breaking the drill bit can be generated, and the invention discloses a deep hole processing combined joint applied to an external cold-turning and internal cold numerical control boring and milling machine, which solves the problem of high-speed processing of deep holes.
In this way, the utility model relates to a be applied to deep hole processing combination joint of cold numerical control boring and milling machine in outer cold-turning combines high-pressure gas and the cooling system of cold numerical control boring and milling machine in outer cold-turning, has reached and has not needed under the condition of dedicated deep hole processing device on the cold numerical control boring and milling machine in outer cold-turning, just can realize the processing of deep hole, and efficient, with low costs.
