Description

Machine tool spindle with stroke adjusting mechanism Technical Field The utility model relates to the technical field of machine tool spindles, in particular to a machine tool spindle with a stroke adjusting mechanism. Background The main shaft of the machine tool is a shaft which drives a workpiece or a cutter to rotate on the machine tool, is one of core components of the machine tool, and the lever clamping main shaft is a mode for clamping the main shaft in the machine tool and is often applied to various processing equipment which needs high-precision and reliable clamping. When the lever clamps the main shaft and carries out clamping force adjustment, often realize the adjustment of clamping force through the removal of removal ring, remove the in-process at the removal of removal ring, mostly manual control swivel becket rotates, and when in actual use, the in-process of manual rotation can appear swivel becket rotation angle and be difficult to accurate control, leads to the clamping force unable to reach anticipated numerical value, and then influences the stability of work piece centre gripping, proposes a lathe main shaft with stroke adjustment mechanism for this. Disclosure of utility model The utility model aims to solve the problem that the clamping force cannot reach an expected value due to the fact that the rotation angle of a rotating ring is difficult to accurately control in the manual rotation process, so that the stability of workpiece clamping is affected. The utility model adopts the following technical scheme for realizing the purposes: a machine tool spindle with a travel adjustment mechanism, comprising: the driving shaft is internally provided with a clamping sleeve and a connecting pipe respectively, the connecting pipe slides in the driving shaft, the clamping sleeve is arranged at one end of the driving shaft and is connected with the connecting pipe, and the outer side of the connecting pipe is connected with a shifting fork in a sliding manner; The adjusting structure is arranged outside the connecting pipe and used for controlling the stroke of the connecting pipe, the adjusting structure comprises a moving part and a locating part, the moving part is arranged outside the connecting pipe and used for controlling the moving range of the shifting fork, the locating part is arranged outside the moving part and used for locating the moving position of the moving part, and the moving part cooperates with the locating part to adjust the moving distance of the connecting pipe. Further, a belt wheel is arranged on the outer side of the driving shaft. Further, the moving part comprises a plurality of moving rings, the moving rings are in threaded connection with the connecting pipes, the moving rings are distributed on two sides of the shifting fork, a connecting groove is formed in one end of each moving ring, a plurality of pressing plates are arranged in the connecting groove, a squeezing ring is arranged in the connecting groove, the squeezing rings are in threaded connection with the connecting groove, moving grooves are formed in the outer side of each moving ring, and the moving grooves are in a plurality.
