For example, a motor lead screw may be used to control the extension and retraction of the piston rod 35. However, the control mode of the motor is complex, the cost is higher, and the matching degree with the jig is lower, so that the embodiment adopts the air cylinder as the power source of the piston rod 35 as the preferred mode, the mode can effectively open a plurality of air cylinders of the jig in groups without electric control, and the use of an electric cabinet on the jig can be reduced.
Before the grouping start device of this embodiment works, the air inlet nozzle assembly 113 of the grouping cylinder body and the air inlet nozzle 34 of the control end of the air cylinder body 37 need to be connected through a pipe, and share one air source. The return end air inlet nozzle 31 of the cylinder block 37 is connected with another air source through a pipe. And the first air outlet nozzle assembly 17, the second air outlet nozzle assembly 15, the third air outlet nozzle assembly 14 and the fourth air outlet nozzle assembly 13 are respectively connected with corresponding cylinders which need to be controlled through pipes according to the working sequence. When the four air cylinders are just treated, the number of each air outlet nozzle assembly just corresponds to the number of the air cylinders, and only one-to-one correspondence connection is needed at the moment. The device is also applicable when the number of cylinders to be controlled is less than the number of outlet nozzle assemblies. At the moment, a plurality of cylinders are connected by controlling a plurality of cylinders, and the redundant air outlet nozzle assembly is blocked by a sealing piece. The device of the embodiment is suitable for a jig provided with 2-4 groups of cylinders.
The working principle of this embodiment is as follows: the common air source connected with the air inlet nozzle assembly 113 and the control end air inlet nozzle 34 is opened, at this time, the first air inlet nozzle assembly 113 is used for introducing air into the air accommodating space of the grouping cylinder body, the first air outlet nozzle assembly 17 is used for introducing air into the first group of cylinders to be controlled, and the first group of cylinders are started. Simultaneously, the control end air inlet nozzle 34 of the cylinder block 37 is also filled with air, the air pushes the piston head 36 leftwards along the cylinder block 37, meanwhile, the piston 112 is driven to move leftwards along the grouping cylinder body, when the piston 112 moves leftwards by more than 50mm, the second air outlet nozzle assembly 15 is filled with air to the second group of cylinders, and the second group of cylinders starts to start. When the piston 112 continues to move to the left beyond 50mm, the third nozzle assembly 14 vents gas to the third set of cylinders, which begins to actuate. When the piston 112 continues to move to the left beyond 35mm, the fourth air outlet nozzle assembly 13 is vented to the fourth set of cylinders, which are started. At this time, the four groups of cylinders are all started, and the control action is completed. During the leftward movement of the piston 112, the gas in the grouping cylinder on the left side of the piston 112 is discharged through the gas discharge hole 19. When the piston rod 35 is required to reset, the common air source for starting is firstly turned off, then the air source at the air inlet nozzle end of the reset end is turned on, the air pushes the piston head 36 rightwards until the piston rod moves to the right, and then the piston rod stops, and the reset work is finished. During the resetting, the grouping cylinder on the left side of the piston 112 sucks air through the exhaust hole 19.
As shown in fig. 6, the four state structure diagrams of the four groups of cylinders in the working process of the present embodiment are shown.
If the number of cylinder groups to be controlled is less than four, the control method is the same as described above.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
