Description

Technical Field

[0001] The utility model relates to the technical field of maintenance fixtures, in particular to an adaptive pressure compensation hydraulic maintenance fixture. Background Art

[0002] Hydraulic clamps are a type of clamp that replaces traditional mechanical components by integrating hydraulic components. They can achieve efficient, automatic positioning, stable support and precise clamping of workpieces. Their significant advantages are that they provide strong clamping force, ensure clamping reliability, operate smoothly and are easy to operate. Therefore, they are widely used in modern manufacturing fields such as CNC machine tools, machining centers and automated production lines.

[0003] However, hydraulic clamps also face some challenges. Due to the different shapes of workpieces, the surface may be uneven. The current clamping device mainly relies on the rough clamping method of the hydraulic cylinder, which often leads to unnecessary gap errors between the pressure plate and the workpiece, thus affecting the processing precision and positioning accuracy. What is more serious is that when the pressure plate rotates with the workpiece, the pressure plate will exert a radial force on the clamping device in contact with it. This force will be further transmitted to the piston rod of the hydraulic cylinder, causing a radial gap between the piston rod and the piston. This will not only cause leakage on the hydraulic sealing surface, reduce system pressure, and make the clamping action ineffective, but may also cause safety hazards and seriously affect the processing accuracy. In view of this, in-depth research on the above-mentioned problems has led to the creation of this case. Utility Model Content
