Description

Technical Field

[0001] The utility model relates to the technical field of fixing and clamping equipment, in particular to a hydraulic oil cylinder piston rod fixing and clamping equipment. Background Art

[0002] The hydraulic cylinder piston rod is a connecting component that supports the piston to do work. It is mostly used in oil cylinders and air cylinder motion actuators. It is a moving component that moves frequently and has high technical requirements. It can assist in completing different production and manufacturing. When processing or installing the hydraulic cylinder piston rod, a fixed clamping device is generally used to clamp and fix the hydraulic cylinder piston rod, thereby facilitating the processing or installation of the hydraulic cylinder piston rod.

[0003] In a Chinese patent with authorization announcement number CN219466122U, a hydraulic cylinder piston rod fixing and clamping device is disclosed. This patent installs a buffer spring. When the hydraulic cylinder piston rod is subjected to external force and generates vibration force during processing, the force can be absorbed by the buffer spring, so that the force applied to the hydraulic cylinder piston rod during processing can be effectively buffered, avoiding damage to the hydraulic cylinder piston rod, and ensuring that the vibration generated by the processing will not affect the stability of the hydraulic cylinder piston rod fixation; however, when clamping and fixing hydraulic cylinder piston rods of different sizes, the elastic force of the spring needs to be adjusted. However, it is difficult for the above-mentioned hydraulic cylinder piston rod fixing and clamping device to adjust the spring force, so it is difficult to use the same spring to meet the impact force generated by hydraulic cylinder piston rods of different sizes during processing, thereby affecting the buffering effect, easily causing damage to the hydraulic cylinder piston rod, and increasing the cost of use. Therefore, we propose a hydraulic cylinder piston rod fixing and clamping device. Utility Model Content
