Description

Technical Field

[0001] This utility model relates to a tooling for assembling the main body of a rotary platform, belonging to the field of engineering machinery technology. Background Technology

[0002] The slewing platform is the main component of the rotary drilling rig. It needs to be connected to the luffing mechanism, chassis, engine, and counterweight. During operation, it has high requirements for the dimensions and geometric tolerances of some hole diameters and spans.

[0003] Before welding, the main body of the rotary platform needs to be positioned for assembly. In the existing technology, the assembly of the main body of the rotary platform is all done by manual measurement. Workers need to measure each part. Therefore, manual measurement has large errors and low efficiency.

[0004] While existing technologies combine human intervention with machine-assisted measurement, such as intelligent robots with multi-axis gripping capabilities that can automatically grasp parts and assemble them according to a preset program using a vision recognition system, these robots are too expensive and unsuitable for large workpieces. Furthermore, during the assembly process, the complex environment can lead to workpiece drops if the robot's gripping is unstable or the workpiece positioning is inaccurate, potentially causing injury to personnel and equipment. Utility Model Content

[0005] Purpose of the utility model: The purpose of this utility model is to overcome the shortcomings of the prior art and provide a jig for assembling the main body of a rotary platform. By using multiple positioning components, the jig can position multiple components such as the front and rear base plates, main and auxiliary upright plates, and reducer mounting plate of the main body of the rotary platform, thereby improving the efficiency and accuracy of the assembly and saving manual measurement procedures.

When the first screw rotates, it drives the first slide to move along the first guide rail. When the first slide moves, it can drive the first gap positioning block on the first column to move until it abuts against the front main plate.
