The head end of the cutter handle is mostly provided with a conical part which is provided with a notch for inserting and welding the cutter body. In the cutting process, cooling water is conveyed to a cutting area by virtue of the tool holder, on one hand, the cooling water is used for cooling the cutting area, the problem that cutting heat is too high and cutting chips cannot be discharged in time is avoided, and on the other hand, part of cutting chips are driven by virtue of the impact force of the cooling water, so that the cutting chips are prevented from being blocked.

However, in chip machining, the water yield is often insufficient, which leads to chip blockage, and especially in deep hole machining and blind hole machining, the cutting machining area cannot be sufficiently cooled, which leads to over-high cutting heat, and the cutting cannot be timely discharged, which leads to workpiece rejection, unstable size, cutter breakage and the like.

Therefore, in order to overcome the defects, a knife handle capable of enhancing water pressure is required to be arranged so as to overcome the defects in the prior art.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a pressurizing cutter handle which can increase the internal cooling water outlet pressure under the condition of not increasing the equipment investment, fully cool a processing area, and adjust the water outlet pressure through an adjusting screw so as to meet the water outlet pressure requirements under different working conditions and different conditions.

In order to achieve the purpose, the utility model adopts the following technical scheme:

a pressurizing knife handle comprises a knife handle body, wherein an inner cooling water channel axially penetrating through the knife handle body is arranged on the knife handle body, an air inflow adjusting channel and an air inlet channel are arranged on the knife handle body, the air inflow adjusting channel is communicated with the inner cooling water channel and the external air pressure, the air inlet channel is communicated with the air inflow adjusting channel and the external air pressure, and an adjusting device for adjusting the air inflow of the air inlet channel is arranged in the air inflow adjusting channel;

correspondingly, the knife handle body comprises a BT taper handle, an SK taper handle, a CAT taper handle, an HSK taper handle and a straight handle;

correspondingly, the adjusting device comprises an adjusting screw, an internal thread is arranged in the air inflow adjusting channel, the adjusting screw is in threaded connection with the internal thread, and the shielding degree of the adjusting screw on the air outlet of the air inflow channel is adjusted by adjusting the screwing depth of the adjusting screw into the air inflow adjusting channel, so that the purpose of adjusting the air inflow of the air inflow channel is achieved;

correspondingly, a joint mounting structure is arranged in the inner cooling water channel, a water inlet pipe is arranged in the joint mounting structure, and the joint mounting structure is connected with a water outlet device on a machining center, a numerical control milling machine or a special machine through the water inlet pipe;

correspondingly, the inlet tube is in the air input regulation passageway with the intersection of interior cooling water passageway, just the lateral wall of inlet tube with there is the clearance in the end of giving vent to anger of air input regulation passageway, both can prevent with the help of the pipe wall of inlet tube that water from gushing into the air input regulation passageway, can guarantee again that gas gets into from the air input regulation passageway, realizes the supercharging.

The utility model has the beneficial effects that:

1) the air inlet adjusting channel and the air inlet channel are arranged on the cutter handle body, and air is introduced into the cutter handle body, so that the phenomenon that chips are blocked when the internal cooling water yield is insufficient and the cutting area cannot be sufficiently cooled, the cutting heat is too high, the cutting cannot be timely discharged, and the phenomena of scrapping of workpieces, unstable size and breakage of cutters are caused are avoided; 2) the air input is adjusted through the adjusting screw, so that the water outlet pressure is adjusted, and the water outlet pressure is suitable for pressure requirements under different working conditions and different conditions.
