Description

Technical Field

[0001] This utility model belongs to the field of oil-free compressor technology, and in particular relates to an oil-free compressor piston rod straightening device. Background Technology

[0002] In the industrial production field, oil-free compressors, due to their characteristic of discharging gas without oil, are widely used in industries with high requirements for gas cleanliness, such as food, pharmaceuticals, and electronics. As a key connecting component inside the oil-free compressor that supports the piston in performing work, the piston rod's operating state directly affects the compressor's efficiency and service life. The piston rod is usually a long cylindrical structure, and during the compressor's operation, it needs to constantly reciprocate, making it one of the most frequently moving components in the entire equipment. In actual use, due to various factors such as load eccentricity and long-term fatigue wear, the piston rod is prone to instability and bending. Once the piston rod bends, it will not only lead to a decrease in the compressor's operating accuracy and increase energy consumption, but may also cause abnormal wear between the piston and cylinder wall. In severe cases, it may even cause the compressor to shut down, resulting in significant economic losses for the company. To restore the normal performance of the piston rod, it is necessary to straighten the bent piston rod.

[0003] Currently, existing piston rod straightening devices mainly use pressure head to straighten the piston rod. In the specific operation, the operator needs to first identify the bent parts on the piston rod, and then operate the pressure head to apply pressure to these bent parts one by one to achieve the straightening purpose. On the one hand, when straightening different bent parts of the piston rod, the operator needs to manually flip the piston rod so that the bent parts at the bottom face upwards so that the pressure head can apply pressure accurately. This operation requires the operator's physical strength. On the other hand, the manual flipping operation makes the entire straightening process inefficient. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an oil-free compressor piston rod straightening device, which solves the technical problem that when straightening different curved parts of the piston rod, the existing piston rod straightening device requires workers to manually flip the piston rod so that the lower curved part faces upward so that the pressure head can apply pressure accurately. This operation requires the workers' physical strength. On the other hand, the manual flipping operation makes the entire straightening process inefficient.

A sliding sleeve 5 is slidably mounted on the crossbeam 12, and a first servo cylinder 6 is fixedly mounted on the bottom surface of the sliding sleeve 5. A pressure head 7 is fixedly mounted on the telescopic end of the first servo cylinder 6. One end of the rotating shaft 20 passes through the connecting plate 19, and a gear 22 is fixedly mounted on the other end of the rotating shaft 20.

The other end of the first screw 9 is rotatably connected to the column 4, and the first screw 9 is threadedly connected to the sliding sleeve 5.
