Technical Field
[0001] The utility model relates to precision processing equipment and a tool used therefor, in particular to a deep hole leveling tool. Background Art
[0002] After a deep hole is obtained through drilling, it is necessary to smooth the inner hole in some cases. However, the deep hole cannot have good coolant flow in and out. The heat generated between the tool and the workpiece during the inner hole smoothing will affect the tool life. At the same time, the temperature increase also makes it impossible to guarantee the smoothness of the inner wall of the deep hole.
[0003] Therefore, it is necessary to provide a deep hole leveling tool to solve the above problems. Utility Model Content

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:
[0006] A deep hole flattening tool comprises a tool handle connected to a flattening tool body, the flattening tool body comprising a cutting edge; an upper coolant input channel and a lower coolant input channel are respectively provided corresponding to the front end and the cutting edge of the flattening tool body;
[0007] The upper coolant input channel is connected to the coolant, and cooling and flushing are performed from the front end of the blade part, forming an overall downward cooling and flushing structure. The lower coolant input channel is connected to the coolant, and cooling and flushing are performed from the blade area of the blade part, forming a precise cooling structure of the blade, and the combination forms a deep hole flat structure during efficient cooling.
[0008] Furthermore, the apertures of the upper coolant input flow channel and the lower coolant input flow channel are both 2-3 mm.
[0009] Furthermore, the flat blade body is connected to the blade handle via a blade body connecting column.
[0010] Furthermore, a first reduction avoidance area is provided between the tool handle and the tool body connecting column, and the height of the first reduction avoidance area is 15%-20% of the diameter of the flat tool body.
[0011] Furthermore, a second step-down avoidance area is provided at the connection between the tool body connecting column and the flat tool body, and the outlet of the upper coolant input channel is located in the second step-down avoidance area.
[0012] Furthermore, the blade portion has a plurality of blades, and corresponding to each blade, a precise blade coolant outlet is provided in the lower coolant input channel.
[0013] Compared with the existing ones, the utility model is connected to the coolant through the upper coolant input channel, and cooling and flushing are carried out from the front end of the blade part to form an overall downward cooling and flushing structure. The lower coolant input channel is connected to the coolant, and liquid cooling and flushing are carried out from the blade area of the blade part to form a precise cooling structure of the blade. The tool has a long service life and effectively guarantees the quality of deep hole flatness. BRIEF DESCRIPTION OF THE DRAWINGS
