Description

Polishing device for outer tube of gas spring Technical Field The utility model relates to the technical field of gas spring pipe fitting machining, in particular to a polishing device for a gas spring outer pipe. Background The gas spring is a mechanical element which utilizes the compressibility and restoring force of gas to realize the functions of supporting, buffering, damping and the like, and is generally composed of a sealed pressure container (cylinder body), a piston rod and compressed gas filled in the cylinder body, when external force acts on the piston rod, the volume of the gas in the cylinder body can be changed, so that corresponding pressure change is generated, the pressure change can be used for providing supporting force or absorbing impact energy, the pressure container is composed of a stronger metal outer tube, and the outer tube is required to be polished after the production is finished so as to eliminate burrs and uneven parts on the surface, thereby achieving the purpose of leveling and smoothing the surface and facilitating the use. The current device that polishes is carried out to outer tube, mainly by the driving roller of polishing under a pair of motor drive, and be located the guide supporting component of driving roller both sides of polishing, guide supporting component has the restriction guide tube that contains the outer tube that waits to polish and stably pass, its effect is that can keep polishing outer tube stable pass between two driving rollers of polishing, make outer tube carry out steady work of polishing, however because the fixed size pipe fitting that restriction guide tube in the guide supporting component is as an organic whole, and the distance between two driving rollers of polishing in the device is also fixed unchangeable, this leads to the device only to the outer tube of fixed external diameter size work of polishing, be difficult to satisfy the demand of polishing to different external diameter outer tubes, the outer tube of different dimensions is polished and is relied on the equipment that is equipped with many sets of adaptations, the cost of using has been increased, the holistic commonality of device is lower, the practicality is not strong.
