The utility model proposes non-high frequency plasma cutting gun can be assembled with method comprising the following steps, wrap
It includes：
Step a. piston rods are fitted into from the bottom of piston cavity in the piston cavity；
Step b. piston rings are arranged by being fitted at the top of piston cavity in the piston motion cavity mounted on described
The head of piston rod；
Step c. springs are set in the piston rod by being fitted at the top of piston cavity in the piston cavity
Head；
Step d. piston caps are mounted on the head of the piston cavity.
The utility model has the beneficial effects that the bottom end for stretching out in the piston rod of piston cavity has than similar product bigger
Diameter, have higher intensity, will not because bottom by external impacts and cutting fever after deform, reduce due to machinery damage
Hinder the deformation for the piston rod bottom end brought and influence electrode large assembly, while avoiding due to cumulative errors and insulating materials change
The size that shape is brought is inconsistent, solves the problems, such as that other products rely on electrode or insulating materials to complete positioning.By piston rod
Head sizes are promoted to 8-9.5mm (diameter of screw thread is M5) by original 6-7mm, avoid the threaded walls due to original piston rod
The thin piston rod head deformation easily caused or sliding tooth；Due to the wall thickness equivalent to increase piston rod end, avoid due to
The deformation that mechanical damages are brought such as fall；Avoid due to long-time cutting fever after material softening cause piston or more interrupted and
Burn pipette tips.The assembly method is compared to previous traditional technique side for carrying out integral type installation down by piston cavity top
Formula is improved to split type assembling mode, and piston rod is fitted into from the bottom of piston cavity in piston cavity, can be met
Increase the requirement of the size of the end of the piston rod of connection electrode.One-piece piston bar can only be installed from top to bottom, result in work
Stopper rod head sizes cannot be excessive, otherwise influences installation and the function of the structure of insulating materials and other component, and newly designs
The piston rod head larger that can make of mounting means from the bottom up, meet the needs of actual use.
