A quick-change pressing mechanism for a hydraulic clamp for a cylinder block

Abstract

The invention relates to a quick-change pressing mechanism for a hydraulic clamp of a cylinder body, which comprises a support component and a shape-changing component. When changing the shape, the shape-changing component can be taken out by rotating the shape-changing component at a certain angle. The invention has the effects of quick model change, simple structure, easy operation and high flexibility, can achieve the purpose of being compatible with different models for co-line production, and can improve work efficiency.

Description

technical field [0001] The invention relates to a pressing mechanism, in particular to a quick-change pressing mechanism of cylinder hydraulic clamps, and relates to the field of engines. Background technique [0002] For a series of cylinders and multiple models, the shape of the cylinders of each model is quite different. The existing hydraulic clamps are generally realized in three ways: the first is to design a single-level clamp according to the height difference of each model of the series of cylinders. High block, when the workpiece is changed and clamped, it is necessary to manually place the equal height block on the top surface of the workpiece for clamping; the second is to design different hydraulic clamps according to different models, and replace the corresponding hydraulic clamps when changing models; The third is that the compression mechanism adopts an integral serial design, and the entire compression mechanism of the corresponding model can be replaced whe...

Problems solved by technology

The first method requires manual operation when changing the model or loading and unloading each workpiece. It is extremely inconvenient to load and unload the workpiece. It is only suitable for sample processing and is not suitable for batch production.

The second way is to re-adjust the accuracy of the fixture in the machine tool and the precision of the workpiece during the type change. The time for the type change is longer, the quality of the workpiece after the type change fluctuates greatly, and the initial investment cost and later maintenance cost are high; the third. In this way, the entire pressing mechanism needs to be disengaged from the clamp body and the part connected to the oil cylinder when changing the type. The moving components are hard-connected, which is inconvenient to operate, labor-intensive, and takes a long time to change types.
