Problems solved by technology
The centering and pressing of the turntable clamping are all manually adjusted to tighten the screw. The clamping effect largely depends on the skill level of the workers, so it is difficult to guarantee the consistency of the pressing force of the turntable and the processing quality. consistency
Moreover, the labor intensity of the workers is high, and the clamping efficiency is low

The invention discloses a processing fixture and a clamping method for a turntable of a crane. The processing fixture includes a fixture platform and two centering clamping mechanisms. The two centering clamping mechanisms are respectively arranged at the front and rear ends of the fixture platform to center the front hinge point hole and the rear hinge point hole of the crane turntable. Clamping, centering The clamping mechanism includes a main structure and two centering structures symmetrically arranged on the left and right sides of the main structure, and the two centering structures move synchronously and reversely relative to the main structure to clamp the crane turntable. The processing fixture of the present invention adopts two centering clamping mechanisms respectively located at the front and rear ends to automatically realize the centering and positioning of the turntable, has a high degree of automation, improves the processing quality and improves the efficiency of centering and clamping.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a processing fixture and a clamping method for a turntable of a crane. Background technique [0002] The crane turntable is an important structural part of the crane, and the outrigger is assembled on the crane turntable to complete the hoisting action. Since the assembly of the outrigger and the turntable is realized through the front hinge point hole and the rear hinge point hole set on the turntable, the processing quality of the front hinge point hole and the rear hinge point hole of the turntable is an important quality control point in the turntable processing. . The clamping effect of the turntable directly affects the processing quality of the front hinge point hole and the rear hinge point hole of the turntable. [0003] At present, the fixture of the turntable mainly includes a backer, a screw, a pressure plate and a threaded rod. The centering and pres...
