Description

A sub-package workbench for heavy-duty vehicles

technical field

The invention relates to a sub-assembly workbench for heavy-duty vehicles, in particular to a workbench device which uses a specific fixing device to fix and position related parts for vehicle assembly, and belongs to the field of production equipment.

Background technique

With the continuous improvement of the social and economic level and the globalization of market competition, the automobile industry must make timely adjustments and changes to major automobile manufacturers in order to seek better development. Traditional automobile assembly adopts the method of superimposing parts one by one, with more stations, longer assembly lines, and lower assembly efficiency.

For the assembly of heavy trucks nowadays, due to the relatively large assembly parts, the assembly work is relatively difficult, and there are few types of lifting fixtures. Due to the large number of stations and various types of parts, the degree of assembly automation is low. Among them, the rear drive axle part is difficult to assemble due to its centralized structure, and due to the large left and right spans of assembly, it requires a lot of labor and takes a long time to consume.

Contents of the invention

In view of the above disadvantages, the present invention provides a sub-assembly workbench for heavy-duty vehicles.

The main support column of the platform is placed horizontally, the worm is installed with the worm bracket on the main support column of the platform, the worm gear and the worm are meshed and installed, the motor is fixed on the motor mounting frame with bolts, the platform rotating shaft is connected with the worm gear by a shaft, and assembled concentrically on the Above the main support column of the platform, the platform support plate 1 is fixed and installed in the middle of the platform rotation shaft through the bolt connection of the support plate 1 screw hole and the rotation shaft screw hole, and the two platform support plate 2 are placed symmetrically on both sides of the platform support plate 1. The installation is fixed through the bolt connection between the two large screw holes of the platform support plate and the screw holes of the rotating shaft. The four drive axle brackets are separated into four corners and are symmetrical in pairs. Fixed installation, the two balance shaft brackets are placed symmetrically, and the screw holes of the balance shaft bracket are connected with the second small screw hole of the platform support plate with bolts for fixed installation. The axis coordinates telescopic movement.

The size of the drive axle fixing groove of the drive axle support is consistent with the width of the rectangular part of the drive axle.

The inclination of the lower push rod fixing groove of the drive axle bracket is consistent with the inclination of the lower push rod during overall installation.

The positions of the positioning holes of the guardrail are the same as the positions of the bolts on the driving axle.

The guardrail has a rectangular slot having the same thickness as the second platform support plate, and fits into the second platform support plate.

The balance shaft fixing groove of the balance shaft support corresponds to the groove on the balance shaft.

The advantage of this invention is that the use of the workbench reduces the length of the total assembly line and reduces the assembly cost; the platform uses worm gears to rotate the platform, which reduces the working space compared with the assembly line type, and the installation position can be moved without The drive axle is fixed by the symmetrical drive axle bracket, which is simple in structure and convenient to assemble; the balance shaft is fixed by the balance shaft fixing groove, so that the assembly space is not affected; the setting of the guardrail is conducive to ensuring the accuracy of the position of the parts during installation.
