The lubrication holes 11 are arranged at a plurality of positions, the lubrication holes 11 are distributed at equal intervals from top to bottom along the cutting edge track of the cutter body 1, and the lubrication holes 11 are filled with miniature one-way valves.
In the embodiment, according to the structural characteristics that the memory alloy 9 can be restored to the initial state when heated, the reamer is fixed on the drill clamp of the machining equipment by utilizing the clamping platform 2, at the moment, the top end of the cutter body 1 is closed by the inner cavity of the drill clamp, when the machine head of the drill clamp random machining equipment rotates, the cutter body 1 carries the diamond cutter head 3 to synchronously rotate, the machine head descends to lead the diamond cutter head 3 to aim at a workpiece hole to conduct reaming operation, the diamond cutter head 3 is enabled to rapidly heat in a shorter time along with the fact that the diamond cutter head 3 continuously stretches into the hole from the top end of the workpiece hole to conduct cutting on the hole wall, and the feeding speed of the diamond cutter head 3 is gradually reduced along with the fact that the length of the diamond cutter head 3 stretching into the hole is longer and the fact that the inside of the hole is outwards chip removed, at the moment, because the diamond cutter head 3 is in a high-temperature state and according to the heat transfer principle, the high heat is transferred to the second storage chamber 5 through the outer wall of the diamond tool bit 3, because the lower half part of the memory alloy 9 is positioned in the second storage chamber 5 under the action of the falling and pulling of the pushing seat 10, the spiral state (similar to a long spring) of the memory alloy 9 at the initial screw pitch is in the elongated large screw pitch state, and according to the performance characteristics of the memory alloy 9, the memory alloy 9 is restored to the initial state (spiral state) when being subjected to high temperature, therefore, when the high heat in the second storage chamber 5 is transferred to the memory alloy 9 after being concentrated, the memory alloy 9 is restored to the initial state, the elongated state of the memory alloy 9 is changed into the shortened state of fig. 7, the pushing seat 10 is uniformly lifted along the wall of the second storage chamber 5 by the restoring action of the memory alloy 9, the second storage chamber 5 is filled with lubricating oil, the lubricating oil rises along the second storage cavity 5, and because the lubricating oil in the second storage cavity 5 is communicated with the lubricating oil in the first storage cavity 4, the top end of the first storage cavity 4 is propped in the drill clamp at the moment because of the top end of the cutter body 1, so that the top end of the first storage cavity 4 is in a closed state, when the push seat 10 uniformly rises along the hole wall of the second storage cavity 5, the lubricating oil filled in the second storage cavity 5 props up the micro one-way valve to flow onto the outer wall of the diamond cutter head 3 from the lubricating hole 11, and the lubricating oil is smeared in the workpiece hole along with the high-speed rotation of the diamond cutter head 3, so that the workpiece hole is cooled while being lubricated, and the diamond cutter head 3 can be prevented from being broken due to torque formed by the high-speed rotation when the feeding speed of the diamond cutter head 3 is too high. Manual operation is not needed in the lubrication process, and potential safety hazards are avoided. And as the depth of the drilled hole continues to deepen, the heat transferred from the diamond tool tip 3 to the second storage cavity 5 will get hotter and hotter, which will allow the memory alloy 9 to continue to rise, thus allowing the push base 10 to continue to rise and continuously smear the lubricant in the second storage cavity 5 onto the diamond tool tip 3 in the manner described above to obtain continuous lubrication until the deep hole is reamed, i.e., if the work hole being reamed is shallower, a shorter diamond tool tip 3 with the same function is selected, and if the work hole being reamed is deeper, a longer diamond tool tip 3 with the same function is selected. I.e. the length dimension of the second reservoir 5 and the length of the memory alloy 9 are chosen to be dependent on the different lengths of the diamond tips 3, i.e. the diamond tips 3 may be exchanged during actual use.
The reamer with the longer structure can be used for reaming a plurality of shallow holes, when one workpiece hole is reamed, the diamond tool bit 3 can rise once due to high heat concentration in the second storage cavity 5 until a large number of shallow holes are reamed in batches, and when oil is not discharged, the completion of pushing of the lubricating oil in the second storage cavity 5 is proved, namely, at the moment, the memory alloy 9 is restored to a state that the pushing seat 10 is lifted to leave the lubricating hole 11 and enter the first storage cavity 4, at the moment, the lubricating oil in the second storage cavity 5 is used up, and at the moment, the lubricating oil in the first storage cavity 4 flows into the second storage cavity 5 due to the fact that the aperture of the lubricating oil in the first storage cavity 4 is larger than the aperture of the second storage cavity 5 and is larger than the diameter of the pushing seat 10, at the moment, the cutter body 1 is detached from a drill chuck of the cutter head, and the gland 8 is detached from the top end of the cutter body 1, at the same time, the memory alloy 9 is detached from the whole cutter, the lubricating oil is then fed into the first storage cavity 4, and then the memory alloy 9 is pulled down again under the action of pushing the pushing seat 10, and the first storage cavity 4 is closed again, as shown in the figure, the top end of the memory alloy 9 is closed again, and the top of the memory alloy 9 is stored in the first storage cavity 4 is closed, and the state is closed again, as shown in the figure 8.

It should be understood that the foregoing is only illustrative of the present invention and is not intended to limit the scope of the present invention. It should be noted that any modifications, equivalent substitutions, improvements, etc. made by those skilled in the art without departing from the spirit and principles of the present invention are intended to be included in the scope of the present invention.
