A hole opening device for a guide sleeve

Abstract

The invention discloses a hole opening device for a guide sleeve, which comprises a support assembly, a positioning device and a drill assembly, the positioning device comprises a support plate, a width adjuster and a height adjuster, and the width adjuster comprises an adjustment rod, a connecting plate and a support The adjustment rod passes through the support plate, the upper part of the adjustment rod is fixedly connected with the connection plate, the connection plate is fixedly connected with the support seat, the height adjuster includes the lifting column, the adjustment assembly and the sleeve, and the bottom of the lifting column is fixedly connected with the support seat , the top of the lifting column is fixedly connected with the adjustment assembly; the guide sleeve can be fixed from both sides, and the guide sleeve can be drilled from the bottom to ensure the stability of the guide sleeve structure, and the fixed guide sleeve can be rotated and pushed , so that the opening effect is coherent and uniform, the device is simple to operate, easy to assemble, less difficult to operate the opening effect, and has good use value.

Description

technical field [0001] The invention belongs to the field of production and processing of hardware parts, and in particular relates to a hole opening device for a guide sleeve. Background technique [0002] The guide parts can ensure that the upper and lower dies have an accurate positional relationship when the die is stamped. The most widely used guide parts in small and medium-sized dies are guide posts and guide sleeves. The guide sleeves are mold accessories that are used in conjunction with guide posts to play a guiding role. , generally used in molds or some mechanical equipment. After the guide post and the guide sleeve are assembled, the movable part of the mold base can be guaranteed to move smoothly without any blockage. However, the fit gap between the guide post and the guide sleeve is very small, within 0.005mm , especially the solid inlaid guide bush, if the matching gap with the guide post is too small, it may cause overheating and affect the performance of t...
