Description

Automobile front anti-collision beam assembly fixture Technical Field The utility model relates to an automobile assembly tool, in particular to an automobile front anti-collision beam assembly tool. Background The automobile engine cabin framework is a core structure for bearing a power assembly, resisting collision and transmitting load and mainly comprises a longitudinal beam assembly, a wheel cover assembly, a front baffle plate assembly, a beam assembly, a front anti-collision beam assembly and the like, wherein the front anti-collision beam assembly comprises an anti-collision beam, two energy absorption boxes and two connecting pieces, the connecting pieces are used for connecting and fixing the front anti-collision beam assembly at the front ends of the two longitudinal beams, and the connecting mode is bolt connection. When carrying out the installation operation of car engine cabin skeleton, no matter artifical or manipulator, all need utilize various frock to advance the location to the assembly component, just so can effectively improve the efficiency of beating the screw. When the front anti-collision cross beam assembly and the longitudinal beam are installed, corresponding assembly tools are also needed. Meanwhile, the front anti-collision cross beam assembly is formed by assembling a plurality of components, and sometimes the final finished product piece is deformed to a certain extent due to the action of stress or other external forces, so that the mounting hole sites of the two connecting pieces and the two longitudinal beams cannot be aligned, and the assembly can be performed after manual correction, thereby greatly reducing the production efficiency. Disclosure of Invention The utility model provides an assembly fixture for an automobile front anti-collision beam, which solves the problem that in the prior art, the automobile front anti-collision beam cannot be aligned with an installation hole site of a longitudinal beam in the assembly process. The technical problem is mainly solved by the technical scheme that the assembly fixture for the front anti-collision beam of the automobile comprises a base, a translation seat, two sets of energy absorption box positioning assemblies and an anti-collision beam positioning assembly, wherein the translation seat is horizontally arranged in a sliding mode back and forth relative to the base; the energy-absorbing box positioning assembly consists of a first base, a first bearing table, a mounting frame, a servo electric cylinder, a first cylinder and a second cylinder, wherein the first base is fixed on the translation seat, the first bearing table is horizontally fixed on the first base, the mounting frame is fixed on the first base, the servo electric cylinder is fixed on the first bearing table, the telescopic directions of the servo electric cylinder and the first bearing table are horizontally distributed left and right, a first clamping block is fixed on a push rod of the servo electric cylinder, the first cylinder is fixed on the first base and is opposite to the servo electric cylinder, a second clamping block is fixed on a push rod of the first cylinder, the second cylinder is vertically downwards fixed on the mounting frame, and a third clamping block is fixed on a push rod of the second cylinder; The anti-collision beam positioning assembly is composed of two second bases, two second bearing tables, a third cylinder and a traction rod, wherein the second bases are fixed on the translation seat, the second bearing tables are fixed on the second bases, the third cylinder is horizontally fixed on the translation seat front and back, and the traction rod is driven to move by the third cylinder.
