Abstract

The invention relates to a fastening method suitable for a part with a hole and a device thereof, which belong to the technical field of machining clamps. The device comprises a tensioning pin and a quick tensioning sleeve; the quick tensioning sleeve comprises a shell, a self-locking unit, a magnet pull rod, an outer spring and an outer end cover; the magnet pull rod is arranged at the bottom of the self-locking unit; the bottom end of the magnet pull rod is connected with the outer end cover via the outer spring; the shell is sleeved outside the self-locking unit, the magnet pull rod, the outer spring and the outer end cover; and the tensioning pin is inserted into the quick tensioning sleeve to lock via the self-locking unit. After the device is utilized, the tensioning pin is fixed by effectively matching a steel ball in the self-locking unit with the tensioning pin so as to quickly fix the part on the clamp; the matching of the steel ball and the tensioning pin can be fully automatically realized through the magnet pull rod and a spring component; and moreover, self-locking and unlocking can be conveniently realized by means of the magnetic control of the magnet pull rod; therefore, the method and the device are suitable for large-scale production and machining requirements.

Description

technical field [0001] The invention relates to a fixing method and device used on a fixture, in particular to a fastening method and a device suitable for parts with holes, belonging to the technical field of fixture processing. Background technique [0002] In the machining industry, many parts are perforated thin plate parts, and the clamping of such parts is usually difficult and complicated. Specifically, most common fixing methods are glued or screwed. However, the disadvantage of this method is that it is cumbersome to clamp and disassemble the parts used for fixing. What's more, sometimes the clamping time is several times the processing time, which is inefficient and cannot meet the current mass production and processing requirements. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems in the prior art, and provide a fastening method and device suitable for parts with holes. [0004] The purpose of th...
