Working principle:

a certain number of valve bodies and accessories A are respectively placed into two vibrating plates 59 in one assembly mechanism 5 on the left side, after the two vibrating plates 59 are started to work, the two vibrating plates 59 respectively lower one valve body and one accessory A into two blanking sinking cavities 5101, then the telescopic ends of two positioning cylinders 517 are driven to extend outwards to drive two pushing blocks 518 to be close to each other, and then the valve bodies and the accessories A are respectively sent into two limiting sinking cavities 5102 through two trapezoidal sinking cavities 5104 to prevent the valve bodies and the accessories A from transversely shifting until the valve bodies and the accessories A are respectively clamped into two V-shaped positioning notches 5103 to finish positioning; then, the telescopic end of the first moving cylinder 54 is driven to extend outwards or retract inwards to drive the first moving frame 53 to move towards the fitting a until the first air chuck 57 is located right above the fitting a, then the telescopic end of the first lifting cylinder 56 is driven to extend outwards to drive the first air chuck 57 to move downwards by means of the first lifting plate 55, simultaneously each jaw of the first air chuck 57 is driven to move outwards until the top of the fitting a is located inside each jaw, then each jaw of the first air chuck 57 is driven to move inwards to grip the fitting a, then the telescopic end of the first lifting cylinder 56 is driven to retract inwards to drive the fitting a to move upwards, then the telescopic end of the first moving cylinder 54 is driven to extend outwards or retract inwards to drive the fitting a to move towards the valve body until the fitting a is located right above the opening of the valve body cavity, finally the telescopic end of the first lifting cylinder 56 is driven to extend outwards to drive the fitting a to move downwards until the bottom of the fitting a is loaded inside the opening of the cavity, and then each jaw of the first air chuck 57 is driven to move inwards to grip the fitting a, thus the assembly of the valve body is completed.

A certain number of valve covers and fittings B are respectively put into the two vibration plates 59 in one assembling mechanism 5 on the right side, and then the fittings B are installed inside the valve covers in the same manner to complete the assembly of the valve cover assembly.

Driving the telescopic end of the second moving cylinder 512 in the left material grabbing assembly to extend outwards to drive the first pneumatic finger 516 to move towards the valve body assembly, driving the telescopic end of the second lifting cylinder 513 to extend outwards to drive the first pneumatic finger 516 to descend, and driving the two clamping jaws of the first pneumatic finger 516 to separate from each other until the two clamping jaws of the pneumatic finger 516 are respectively positioned on the front side and the rear side of the valve body assembly, and then driving the two clamping jaws of the first pneumatic finger 516 to approach each other to clamp the valve body assembly; the telescopic ends of the second lifting cylinder 513 and the second moving cylinder 512 are driven to retract inwards to drive the valve body assembly to move upwards and move rightwards, the rotating end of the first rotating cylinder 514 is driven to rotate 180 degrees to enable the valve body assembly to turn over the same angle, the telescopic end of the second moving cylinder 512 is driven to extend outwards to drive the valve body assembly to move leftwards until the valve body assembly is located right above one of the positioning seats 4, the telescopic end of the second lifting cylinder 513 is driven to extend outwards to drive the valve body assembly to move downwards and be placed in the positioning seat 4, and then the two clamping jaws of the first pneumatic finger 516 are driven to separate from each other to loosen the valve body assembly.

Likewise, a gripper assembly on the right would also gripper and move the valve cover assembly over the tray 3 to await preassembly in a similar manner.

When the valve body assembly rotates to the position right below the liquid outlet of the pneumatic dropper 8, the rotary motor 2 is turned off, the pneumatic dropper 8 is started to enable lubricating oil in the pneumatic dropper 8 to extrude out of a part and vertically fall onto the valve body assembly, and in the process, the valve body assembly is installed next time and then placed into the next positioning seat 4.

When the valve body assembly rotates to the position right below the valve cover assembly, the rotating motor 2 is turned off, the telescopic end of the second lifting cylinder 513 in the right material grabbing assembly is driven to extend outwards to drive the valve cover assembly to move downwards and put on the valve body assembly, and then the two clamping jaws of the first pneumatic finger 516 are driven to be separated from each other to loosen the valve cover assembly, so that the preassembly of the valve is completed; in the process, the next valve body assembly completes the oiling operation.

When the preassembled valve rotates to the position right below the pressing plate 651, the rotating motor 2 is turned off, the telescopic end of the pressing cylinder 62 is driven to extend outwards to drive the pressing rod 64 to vertically move downwards in the guide seat 63, and the pressing plate 651 on the pressing seat 65 is further pressed downwards to press the corresponding part of the pressing plate 651 into the valve body assembly, so that the valve assembly is completed; in this process, the next valve body assembly completes the preassembling operation.

Then, the valve body assembly and the valve cover assembly are stopped to be installed and the four positioning seats 4 are continuously driven to rotate, when the assembled valve rotates to the discharging mechanism 9, the rotating end of the second rotating cylinder 95 is driven to rotate 180 degrees to drive the second pneumatic finger 97 to rotate to the valve by means of the rotary plate 96, meanwhile, the two clamping claws of the second pneumatic finger 97 are driven to be separated from each other, when the two clamping claws of the second pneumatic finger 97 are respectively positioned on two sides of the valve, the two clamping claws of the second pneumatic finger 97 are driven to be close to each other to clamp the valve, then the telescopic end of the third lifting cylinder 98 is driven to be contracted inwards to drive the second lifting plate 94 to move upwards, and the valve is driven to move upwards by means of the second rotating cylinder 95 and the rotary plate 96 to be separated from the positioning seats 4; the rotating end of the second rotary cylinder 95 is driven to rotate 180 degrees to move the valve above the upper end of the chute plate 99 in the same way, and finally the two clamping jaws of the second pneumatic finger 97 are driven to be separated from each other to release the valve, and then the valve falls into the chute plate 99 by self gravity, and finally falls into the receiving box 910 along the inclination of the chute plate 99 for automatic collection.

The same method of installation then places all three subsequent valves into the magazine 910 to empty the valves in the four positioning seats 4, after which the installation of the valve body assembly and valve cover assembly and subsequent assembly and discharge can be resumed, with four valves as a set, and so on.

The valve body assembly, the valve cover assembly and the press fitting of the valve body assembly and the valve cover assembly can be automatically realized by using a single device, and manual operation is not needed in the whole process, so that a great amount of time is saved, and the assembly efficiency is greatly improved; in addition, the labor cost is greatly reduced to promote the reduction of the assembly cost, and finally the competitiveness of processing enterprises is effectively improved to be suitable for large-area popularization.
