Abstract

The invention discloses a quick-change type guide sleeve fixing structure comprising a guide sleeve, a cushion block, a die holder, a lower cushion block and a lower template, the lower cushion block is arranged on the die holder, the lower template is arranged on the lower cushion block, and the lower template is internally provided with through holes for installing the guide sleeve; the invention is characterized in that the guide sleeve is provided with a T-shaped hanging boss which hangs outside the bottom of the lower template, the lower template is internally provided with a groove for the T-shaped hanging boss to penetrate through, the lower cushion block is provided with a notch, the cushion block is inserted into the notch to clamp the guide sleeve, and the die holder is internally provided with open holes with diameter larger than that of the guide sleeve. The invention solves the problems in the prior art that replacement time of glue pouring type guide sleeve after abrasion to influence normal production of enterprises and that the die with glue pouring type guide sleeve fixing structure has poor preciseness. The invention is convenient in operation, a new guide sleeve only needs about one hour to replace without needing to reassemble the die, and the structure is stable, thus being of greatly help to quality and production efficiency.

Description

technical field [0001] The invention relates to a guide sleeve fixing structure, in particular to a quick-change guide sleeve fixing structure. Background technique [0002] With the development of science and technology, guide sleeves have been widely used in the stamping industry. Guide sleeves are often used for drilling and boring. Generally, the ones used for drilling are called drill sleeves, and the ones used for boring are called tool bar guide sleeves. The tool rod will not deviate during cutting, so as to improve the dimensional accuracy and position accuracy of the processed hole. In the current stamping industry, the guide sleeve is fixed by pouring glue when assembling the mold. Because the guide sleeve is fixed in the plate with glue, the size of the inner hole on the plate and the size of the guide sleeve are matched by a clearance fit. , so the precision of the mold is low; and the mold stamping for a period of time, the guide sleeve will wear out, if you wa...
