Description

Cutter sleeve capable of adjusting machining range of shock-absorbing cutter Technical Field The utility model relates to the technical field of deep hole machining equipment, in particular to a cutter sleeve capable of adjusting the machining range of a damping cutter. Background The difficulty of turning the inner hole of the part is closely related to the length-diameter ratio, the greater the length-diameter ratio is, the greater the processing difficulty is, and the more difficult the precision is ensured. Currently, an inner hole with an aspect ratio greater than 4 times (i.e. an inner hole length greater than 4 times of the diameter) is defined as an elongated hole, and the most common problem of the elongated hole in the turning process is that a cutter is vibrated during turning, and the precision of the hole can be directly affected by the cutter. In order to meet the processing of the elongated holes, a shock absorbing blade is generally used. The current damping knife technology in the industry is leading mountain Tevick brand, taking the brand as an example, the standard knife specification is 7, 10 and 14 times of diameter, the price of the knife with higher diameter is higher, for example, 80-diameter and 10-diameter knives are 7.2 ten thousand and 14-diameter knives are up to 52 ten thousand, the purchasing cost is improved by 622%, the processing precision can not be met if 10-diameter knives are selected, and if 14-diameter knives are selected, the processing cost is increased, so that the product profit space is further compressed, and the method does not belong to the optimal batch production mode of enterprises. Therefore, how to increase the processing range of the damper blade is a technical problem to be solved by those skilled in the art. Disclosure of utility model In order to solve the technical problems, the utility model provides the cutter sleeve capable of adjusting the processing range of the damping cutter, which can effectively improve the processing range of the damping cutter, ensure the processing precision and save the processing cost. The technical scheme provided by the utility model is as follows: The utility model provides a can make shock attenuation sword machining scope adjustable tool holder, includes the tool holder body, the tool holder body is including being used for the regulation portion of being connected with the cutter and being used for the fixed part of being connected with the blade holder, regulation portion is equipped with the hole of placing that is used for placing the cutter and is connected with the cutter through detachable mode, the central line of placing the hole and the central line of tool holder body are not collinear to form the wall thickness of regulation portion along circumference different, and the highest point of regulation portion wall thickness thinnest department is less than the knife tip of cutter. Preferably, the adjusting part is provided with an adjusting groove which is communicated with the placing hole along the length direction of the adjusting part, the adjusting groove is arranged at the thickest wall thickness of the adjusting part, the adjusting part is also provided with a threaded hole which penetrates through the adjusting groove, and a screw is arranged in the threaded hole. Preferably, the adjusting part is provided with a sinking table, and the initial end of the threaded hole is arranged in the sinking table. Preferably, the number of the sinking tables is not less than two, and the number of the threaded holes is the same as the number of the sinking tables.
