Description

Milling cutter structure with positioning function Technical Field The utility model relates to the field of milling cutters, in particular to a milling cutter structure with a positioning function. Background In the field of modern machining, milling is an important metal cutting machining mode and is widely applied to manufacturing and machining processes of various parts. In conventional milling, an operator must re-perform the tool setting operation whenever the milling cutter needs to be replaced in order to ensure the accurate position and machining accuracy of the milling cutter. This process is not only time consuming, but also requires a certain level of skill on the operator, increasing the uncertainty and risk of human error in the process. In the processing task requiring frequent tool changing, the tool setting time occupies a considerable part of the total processing time, and the improvement of the processing efficiency is restricted. Because the cutter needs to be re-set after each cutter change, the cutter setting difference among different operators, the precision limitation of cutter setting equipment, the change of environmental factors and other factors can cause fine deviation of the position of the milling cutter after each cutter setting. These deviations can be accumulated and amplified when a plurality of workpieces are continuously processed, and finally affect the consistency of processing precision, and reduce the quality stability of products. Disclosure of utility model The utility model aims to provide a milling cutter structure with a positioning function, which solves the problems that the cutter needs to be re-aligned and the operation is complicated and time-consuming when the traditional milling cutter is changed. In order to achieve the purpose, the technical scheme is that the milling cutter structure with the positioning function comprises a cutter handle, one end of the cutter handle is provided with a cutter head, the outer side of the cutter handle is connected with a positioning sleeve in a sliding mode, and the positioning sleeve is provided with an adjusting structure which is used for adjusting the tightness degree between the positioning sleeve and the cutter handle. Preferably, the adjusting structure comprises a threaded rod, the threaded rod is connected with the inner thread of the positioning sleeve, and the threaded rod is perpendicular to the cutter handle. Preferably, the method comprises the steps of, the threaded rod is far away from the knife handle one end of the tube is provided with a hexagonal groove, the threaded rod is conveniently rotated by using tools such as a hexagonal wrench. Preferably, the annular level in outside extends the both ends of spacer, and adjusting structure includes sleeve, spring and ball, and spacer outside sliding connection has the sleeve, and telescopic upper portion internal diameter is unanimous with the spacer external diameter, and sleeve mid portion is loudspeaker form, and sleeve lower part internal diameter is greater than the spacer external diameter, and the spacer outside cover is equipped with the spring, and the sleeve passes through spring and the spacer elastic connection who corresponds, and the inside equidistance sliding connection of spacer has the ball, and the recess that is annular array has been seted up to the equidistance in the handle of a knife outside, and the ball is blocked respectively in the recess of corresponding position department on the handle of a knife.
