Timing chain assembling method and device

Abstract

The invention discloses a timing chain assembling method and a timing chain assembling device, which comprises a first feeding tray, a second feeding tray and a third feeding tray. A chain link step type assembly mode is adopted; the first feeding tray is in an operating state all the time and pushes base plates, pin shafts and inner plates to assembly stations for pressing assembly; the second feeding tray and the third feeding tray enter an operating state at the same time; the second feeding tray stays in an operating state when a mark plate is not assembled and pushes a cover plate to an assembly station for pressing assembly, and when the mark plate is assembled, the second feeding tray enters an idle state and does not push the cover plate; and when the mark plate is not assembled, the third feeding tray is in an idle state and does not push the mark plate, but when the mark plate is assembled, third feeding tray is in an operating state and pushes the mark plate to an assembly station for pressing assembly. According to the technical scheme, the timing mark plates are arranged on the timing chain at positions at different link intervals while the chain is assembled automatically, the processing efficiency is increased and the quality of the chain is ensured.

Description

technical field [0001] The invention relates to the technical field of chain processing, in particular to an assembly method and an assembly device of a timing chain. Background technique [0002] The patent document with the publication number CN101642870A discloses a chain assembly device, including a double column type discharge assembly, a double sheet type string assembly, a horizontal clamp push plate assembly, a press assembly, a positioning assembly, and a chain link progressive assembly. The horizontal clamp push plate assembly is arranged below the double material column type discharge assembly and the double material sheet type serial material assembly. The horizontal clamp push plate assembly can move forward and backward laterally. A positioning assembly is arranged at the position of the press assembly. The longitudinal rear part of the press-fit assembly is a chain link progressive assembly. Among them, the synchronous sub-items of each component are all sepa...

AI Technical Summary

Problems solved by technology

[0003] The feeding tray of the existing chain assembly machine (that is, the feeding seat in the above-mentioned horizontal clamp push plate assembly) is fed in one piece, and each station must be in working condition and send out the same parts every time, so it is impossible to adjust the timing of the chain. Install timing marks on the positions with different intervals

In order to install 3 (sometimes more) timing marking pieces on the timing chain, the assembled chain needs to be disassembled into 4 sections, and then re-linked with colored marking pieces, the chain links of the dismantled parts are changed due to size , The firmness is reduced and it cannot be used. The reinstalled chain links are often assembled by hand, which is not only inefficient, but also the quality of the chain frame is poor during assembly, which reduces the quality of the chain accordingly.
