Table top base convenient for lifting control for automobile welding fixture

Abstract

The invention provides a table top base convenient for lifting control for an automobile welding fixture. The table top base is characterized by comprising supporting mechanisms, a lifting mechanism, a chassis, a bracket, guide rails and sliding connecting shafts; fixed connecting shafts are correspondingly mounted on the front side and the rear side of the left end of the top of the chassis through bolts; the guide rails are welded to the front side and the rear side of the right end of the top of the chassis; sliding connecting shafts are arranged on the upper sides of the guide rails; the chassis is connected with the bracket through the sliding connecting shafts; the lifting mechanism is arranged between the two sliding connecting shafts; and the supporting mechanisms are correspondingly arranged on the left side and the right side of the top end of the chassis. According to the table top base convenient for lifting control for the automobile welding fixture, when a workbench reaches the working height, the auxiliary supporting effect on the left side and the right side can be achieved, so that supporting points of the workbench are increased, a second workbench does not need to be additionally arranged, the space of a plant is not occupied too much, and then the machining efficiency is not affected.

Description

technical field [0001] The invention relates to the technical field of automobile welding, in particular to a platform base for convenient lifting control for automobile welding fixtures. Background technique [0002] Welding production in automobile manufacturing has the characteristics of large batches, fast production speed, and high requirements for the assembly and welding accuracy of the parts to be welded. Most of them adopt flow-line production methods, and different parts need to be welded in different ways. The traditional lifting platform for automobile welding and assembly uses a single The unique scissor lifting design makes the support point of the platform shift when it is lifted, that is, the balance support point of the platform changes, and improper manual operation may easily lead to an unstable center of gravity of the lifting platform and rollover accidents; [0003] In order to improve the defects of the single scissor lift type lifting platform, the li...

[0002] Welding production in automobile manufacturing has the characteristics of large batches, fast production speed, and high requirements for the assembly and welding accuracy of the parts to be welded. Most of them adopt flow-line production methods, and different parts need to be welded in different ways. The traditional lifting platform for automobile welding and assembly uses a single The unique scissor lifting design makes the support point of the platform shift when it is lifted, that is, the balance support point of the platform changes, and improper manual operation may easily lead to an unstable center of gravity of the lifting platform and rollover accidents;

[0003] In order to improve the defects of the single scissor lift type lifting platform, the lifting platform of the prior art is provided with a second scissor mechanism horizontally on the original basis to improve the instability of the balance support point. A second workbench is added horizontally on the side of the workbench, which increases the area of ​​the workbench, making the workbench take up a lot of workshop space, but in order to ensure the speed of automobile welding, the factory needs to install multiple lifting platforms for welding, but , the welding station in the prior art takes up a lot of space, which reduces the number of welding workbenches that can be placed in the workshop. Due to the reduction in the number of workbenches, the number of automobile welding fixtures used with it is reduced, so the production speed will increase with the processing equipment. Reduced and slowed down, reducing production efficiency, and the existing lifting platform relies on the cylinder to push and control the lifting. Since the cylinder is controlled by the air compressor, the driving force is relatively large and the speed is fast when lifting, and the lifting process is not stable. There will be a phenomenon that the welding parts shake with the workbench, which is difficult to control and has low practicability
