Split mounting tool for rear frame of semitrailer

Abstract

The invention provides a split mounting tool for a rear frame of a semitrailer. The split mounting tool comprises a rack, a longitudinal beam positioning mechanism, a rear end beam positioning mechanism and a lock head module positioning mechanism, wherein the longitudinal beam positioning mechanism comprises a stopping unit and a plurality of groups of clamping and centering units; the rear end beam positioning mechanism is arranged at the rear end of the rack; the lock head module positioning mechanism comprises at least one group of positioning clamping units; each positioning clamping unitcomprises a pair of positioning clamping parts; each positioning clamping part comprises a base, a positioning pin and a pair of clamping blocks. When the split mounting tool is used for splitting and mounting the rear frame, a lock head module can be positioned in the X direction, Y direction and Z direction through the lock head module positioning mechanism; the rear end beam positioning mechanism and the longitudinal beam positioning mechanism are matched with each other the position a rear end beam and the longitudinal beam in the X direction and the Y direction. Therefore, the split mounting tool is applicable to split mounting of the rear frames (with lock head modules and without lock head modules) of different types; the applicable scope of the split mounting tool is expanded; andthe flexible production of the rear frames of different types can be performed.

Description

Technical field [0001] The invention relates to the technical field of semi-trailer frame assembly, in particular to a semi-trailer rear frame assembly tool. Background technique [0002] In the prior art, semi-trailers are usually divided into different types, and the rear frames of different types of semi-trailers are also different. Among them, the frame semi-trailer needs to be used in conjunction with the container when transporting goods, and a lock is provided on the rear frame. And the semi-trailer of the flat silo can be used to transport goods directly, and there is no lock on the rear frame. At present, the rear frames of the above-mentioned two types of semi-trailers will be made separately as two completely different models. Each type of rear frame corresponds to a kind of assembly tooling, resulting in a small application range of assembly tooling and cannot be universal. This restricts the flexible production of semi-trailer rear frames. Summary of the invention...
