Illustrate the application method of the present invention below：
Step 1：The anti-mismatch of tensioner ring is spacing and assembles tensioner ring
Transfer feeding servomotor 292 is captured by driving 291 control machinery hand 26 of screw to move by manipulator 26
And release plunger, realize movement of the piston between each station.When piston motion is to the first station 10, limiting cylinder 52 is dynamic
Make, promote the anti-mismatch 53 of tensioner ring to be moved to position as shown in Figure 4, feeding servomotor 71 is exported dynamic by feeding screw mandrel 66
Power, and lower flange 65 is driven by feeding screw mandrel 66, lower flange 65 promotes upper flange plate 62 to move upwards, so as to promote swollen
Ring feeding, tensioner ring are expanded by structure during 67 end of charge bar, fairly fallen in after coming off from charge bar 67 in the groove of piston.
Step 2：Assemble skirt section scraping blade
Manipulator 26 captures piston and is moved to second station 20, and manipulator 26 is determined when capturing piston by the A faces of piston
Position, the end of manipulator 26 and the B faces of piston are coplanar.
Electromagnetic switch is opened, electromagnetic coil 82 is powered, the annular magnetic force of generation around it.Tensioner ring is under the action of annular magnetic force
In floating point, at this time, the central axes of the central axes of tensioner ring just with electromagnetic coil 82 overlap, and closed electromagnetic switch, tensioner ring is outside
Enclosing moment under strong magnetic action is adsorbed, and is fitted closely with the C faces of piston.
Manipulator 26 pushes, and promotes the charge bar 67 of piston and skirt section scraping blade to move down by the A faces of piston, at this time skirt section scraping blade
It is motionless with the charge bar support column 81 of skirt section scraping blade.Continue to push with manipulator 26, the skirt section scraping blade of top is ejected, and is lost
The dilating effect of the charge bar 67 of skirt section scraping blade is removed, skirt section scraping blade recovers original size, falls into the groove of piston.
Step 3：Assemble head scraping blade
Manipulator 26 captures piston and is moved to 3rd station 30, and manipulator 26 is determined when capturing piston by the A faces of piston
Position, the end of manipulator 26 and the C interplanar distances of piston are 0.3mm.
Electromagnetic switch is opened, electromagnetic coil 82 is powered, the annular magnetic force of generation around it.Tensioner ring is with skirt section scraping blade in annular magnetic
In floating under the action of power point, central axes of the central axes of tensioner ring and skirt section scraping blade just with electromagnetic coil 82 overlap at this time, close
Electromagnetic switch is closed, tensioner ring moment under peripheral strong magnetic action is adsorbed, fitted closely with the B faces of piston.
Manipulator 26 pushes, and promotes the charge bar 67 of piston and head scraping blade to move down by the A faces of piston, at this time head scraping blade
It is motionless with the charge bar support column 81 of head scraping blade.Continue to push with manipulator 26, the scraping blade of top loses charge bar 67
Dilating effect, recovers original size, falls into the groove of piston.
Step 4：Assemble the second ring
Piston crawl is put on the charge bar 67 of the second ring by manipulator 26, and feeding servomotor 71 is defeated by feeding screw mandrel 66
Go out power, and lower flange 65 is driven by feeding screw mandrel 66, lower flange 65 promotes upper flange plate 62 to move upwards, so as to push away
Dynamic second ring feeding, the second ring are expanded by structure during the end of charge bar 67, and piston is fairly fallen in after coming off from charge bar 67
In groove.
Step 6：Assemble the first ring
Piston crawl is put on the charge bar 67 of the first ring by manipulator 26, and feeding servomotor 71 is defeated by feeding screw mandrel 66
Go out power, and lower flange 65 is driven by feeding screw mandrel 66, lower flange 65 promotes upper flange plate 62 to move upwards, so as to push away
Dynamic first ring feeding, the first ring are expanded by structure during the end of charge bar 67, and piston is fairly fallen in after coming off from charge bar 67
In groove.
