The hydraulic clamp can bear large cutting force during rough machining, can ensure accurate positioning during precise machining, and can also complete supporting, clamping and quick release which cannot be completed by the manual clamp.
The supporting cylinder is one of hydraulic clamp executing elements, and is an executing element with relatively high technical content. The supporting cylinder is mainly used for supporting and limiting the workpiece, preventing the workpiece from being deformed due to cutting force during machining, and avoiding influencing the machining precision of the workpiece due to vibration during machining. However, during the use of the machining fixture for automobile parts, the existing supporting cylinder tends to retract because: on one hand, the hydraulic system has pulse property and jumping property; on the other hand, the instantaneous hydraulic pulse causes the support point of the support cylinder to retract after reaching the workpiece. In addition, uneven surfaces of the workpiece may also cause a retraction phenomenon. The retraction phenomenon results in the support cylinder not providing effective support, presenting the following conditions: the position of the workpiece is deformed, and the production line and the taper are changed; the workpiece is deformed, the straight line becomes bent, the circular angle becomes sharp, and the like; and the processing generates the phenomenon of leak connection or leak hole. In summary, the retraction of the supporting cylinder in the prior art, and the failure to provide effective support is a main cause of workpiece processing deformation. The source of the retraction is the pulsatility and jerkiness of the hydraulic system itself and the uneven surface of the workpiece. In order to solve this drawback, a new solution is needed that is capable of suppressing the pulsatility of the hydraulic system, avoiding the retraction of the support cylinders, thus providing an effective support.
