Automatic assembling machine of hinge spring shafts

Abstract

The invention belongs to an assembling machine for manufacturing spectacle frames, in particular to an automatic assembling machine of hinge spring shafts, which can continuously and automatically complete the integral assembly of spectacle hinge spring shafts. The traditional assembly of the spectacle hinge spring shafts completely depends on manual operation of workers and has the defects of low assembly speed, long period and low production efficiency due to one-by-one serial connection, and the assembled spectacle hinge spring shafts have great difference and unstable quality due to the limitations of the technical level of the workers, which greatly influences the later actual use of the spectacle frames. Aiming at the defects, the invention provides an automatic assembling machine of hinge spring shafts, which has the technical characteristic that one large rotary table and one small rotary table which are mutually perpendicular are arranged, the rotary tables are provided with a plurality of corresponding through holes and card slots for installing corresponding parts, and the two rotary tables rotate and are mutually matched according to a set beat so as to continuously and automatically assemble the hinge spring shafts. Compared with the traditional manual operation, the invention has high speed and high efficiency, and the finished hinge spring shafts assembled by the machine have uniform specifications, small difference and stable quality.

Description

【Technical field】 [0001] The invention belongs to an assembly machine for producing spectacle frames, in particular to a hinge spring shaft automatic assembly machine which can continuously and automatically complete the overall assembly of spectacle hinge spring shafts. 【Background technique】 [0002] The spring shaft of the spectacle hinge is an important part of the spectacle frame. It is used as a movable joint to connect the stud and the temple on the spectacle frame. curved parts. Hinge spring shaft in kind figure 1 As shown, the whole is very small, consisting of hinge 4, retainer 3, spring 2 and mandrel 1, the mandrel passes through the spring and retainer in turn, and then inserted into the tail hole on the hinge, between the mandrel and hinge The joints are riveted and fixed, and assembled into a hinge spring shaft. The assembly of the existing eyeglass hinge spring shafts is completely dependent on the manual operation of the workers, one by one in series, the ...

AI Technical Summary

Problems solved by technology

The assembly of the existing eyeglass hinge spring shafts is completely dependent on the manual operation of the workers, one by one in series, the assembly speed is slow, the cycle is long, and the production efficiency is low. Due to the limitation of the technical level of the workers, there are great differences in the final assembled hinge spring shafts, and the quality is not good. It is stable and has a great influence on the actual use of spectacle frames in the later stage
