Description

[0002] The piston has a wide range of uses. The piston in the present invention is mainly used for sealing the air inlet of the gas self-closing valve. When the piston is used, it needs to be assembled with the piston rod. At present, most of the piston assemblies used in the self-closing valve industry are assembled manually, and the lower end of the piston rod has no guide. The manual assembly is to hold the piston rod at a certain angle and rub it into the piston through the piston mouth of the piston in circles, thereby realizing the assembly of the piston assembly. Due to the elasticity of the piston itself, a large force needs to be applied when the piston rod is sleeved into the piston for assembly, which causes the staff to lose physical strength quickly and the operation is laborious and inconvenient. In winter, the rubber piston becomes hard, and the assembly is more laborious, which greatly reduces the efficiency. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of the utility model are: the automatic piston assembly equipment has the following advantages:

[0017] 1. Control the swing end of the swing cylinder through an external air pump to drive the positioning tooling to drive the piston rod to rotate upward, and then the control unit starts the two-axis manipulator to move it horizontally to the upper end of the piston rod and drive the clamping claw to move vertically downward to the specified position, and then the control unit starts the clamping claw to close and clamp the upper end of the piston rod, and then the control unit controls the two-axis manipulator to indirectly drive the piston rod to move to the center upper end of the mounting bracket four, and the external air pump causes the guide rod cylinder of the material distribution mechanism to drive the piston to move vertically upward through the customized tooling to the lower end of the spreading fingers, and both enter the bottom of the plug mouth of the piston and cooperate with the customized tooling to tighten the piston, the control unit controls the spreading mechanism to stretch and expand the plug mouth of the piston, and then the control unit controls the two-axis manipulator to indirectly drive the piston rod to move vertically downward and insert the lower end of the piston into the spreading opening of the piston, thereby realizing the assembly of the piston assembly. The piston automatic assembly equipment realizes the automatic assembly of the self-closing valve piston assembly. This method can realize the assembly of similar products, save labor, improve efficiency, and reduce production costs.

[0018] 2. Control the guide rod cylinder through an external air pump so that its telescopic end drives the piston to move vertically to the spreading fingers through the customized tooling. At this time, the four spreading fingers are in contact, and the guide rod cylinder continues to drive the piston upward. At this time, the lower ends of the four spreading fingers all enter the bottom of the plug mouth of the piston and cooperate with the customized tooling to tighten the piston to prevent the piston from flying away due to lack of tightening when it is spread without a hook. The automatic piston assembly equipment uses specially designed fingers to enable the piston to spread in a tightened state to ensure that it will not fly away during spreading.

[0019] 3. The cylinder is controlled by an external air pump. The telescopic end of the cylinder drives the spreading finger to move toward the end away from the piston axis, thereby stretching and expanding the piston plug. Then the control unit starts the two-axis manipulator to indirectly drive the piston rod to move vertically downward and insert its lower end into the spreading opening of the piston. During this process, the downward pressure of the two-axis manipulator is greater than the upward thrust of the cylinder, so that the lower end of the piston rod drives the piston to continue to move downward, so that the piston is separated from the spreading finger and the lower end of the piston rod is elastically contracted and wrapped, thereby realizing the assembly of the piston assembly. The automatic piston assembly equipment adopts a pressing method for assembly. The upper pressing force is greater than the lower pressing force. During the pressing process, not only the piston rod assembly is completed, but also the separation of the spreading fingers is completed. BRIEF DESCRIPTION OF THE DRAWINGS

The control unit 2 turns off the feeding vibration plate 25 and controls the guide rod cylinder 621 through an external air pump so that its telescopic end drives the piston 12 to move vertically to the spreading finger 642 through the custom tooling 622. At this time, the four spreading fingers 642 are in contact, and the guide rod cylinder 621 continues to drive the piston 12 upward.

[0036] The working principle of a piston automatic assembly device provided by the utility model is as follows: when the device is used to automatically assemble the piston rod 11 with the piston 12, the device is first moved to the specified position, and then the guide rod cylinder 621, the cylinder 641 and the swing cylinder 42 are respectively connected to the external air pump, and the control unit 2 starts the human-machine operation screen 8. The staff modifies the instructions of the control unit 2 and observes the operation status of the device through the human-machine operation screen 8.

The detection sensor 44 detects the piston rod 11 through the photoelectric sensing principle and The detection result is transmitted to the control unit 2 in the form of an electrical signal. The control unit 2 turns off the feeding vibration plate 3 and controls the swing cylinder 42 through the external air pump. The telescopic end of the swing cylinder 42 drives the positioning tooling 43 to drive the piston rod 11 to rotate 90 degrees upward. Then the control unit 2 starts the two-axis manipulator 72 to move it horizontally to the upper end of the piston rod 11 and drives the clamping claw 73 to move vertically downward to the specified position. Then the control unit 2 starts the clamping claw 73 to close it to clamp the upper end of the piston rod 11. Then the control unit 2 controls the two-axis manipulator 72 to indirectly drive the piston rod 11 to move to the center upper end of the mounting bracket four 63. At the same time, the control unit 2 starts the feeding vibration plate two 5 to pass the piston 12 inside it according to the specified posture. After vibration, it is transported to the interior of the customized tooling 622 through the piston feed port 13. The detection sensor 2 65 detects the piston 12 through the photoelectric sensing principle and transmits the detection signal to the control unit 2 in the form of an electrical signal. The control unit 2 closes the feeding vibration plate 2 5 and controls the guide rod cylinder 621 through an external air pump so that its telescopic end drives the piston 12 to move vertically upward to the spreading finger 642 through the customized tooling 622. At this time, the four spreading fingers 642 are in contact, and the guide rod cylinder 621 continues to drive the piston 12 upward. At this time, the lower ends of the four spreading fingers 642 all enter the bottom of the plug port of the piston 12 and cooperate with the customized tooling 622 to tighten the piston 12 to prevent the piston 12 from being not tightened when it is spread without a hook. The flying away phenomenon is then controlled by an external air pump. The telescopic end of the cylinder 641 drives the spreading finger 642 to move toward the end away from the axis of the piston 12, thereby stretching and expanding the plug mouth of the piston 12. Then, the control unit 2 starts the two-axis manipulator 72 to indirectly drive the piston rod 11 to move vertically downward and insert its lower end into the spreading opening of the piston 12. During this process, the downward pressure of the two-axis manipulator 72 is greater than the upward thrust of the cylinder 641, so that the lower end of the piston rod 11 drives the piston 12 to continue to move downward, so that the piston 12 is separated from the spreading finger 642 and elastically shrinks the lower end of the piston rod 11, thereby realizing the assembly of the piston assembly. Then, the control unit 2 controls the two-axis manipulator 72 to drive the piston assembly to the upper end of the material channel 9.Then the control unit 2 controls the clamping claw 73 to open so that the piston assembly moves along the material channel 9 into the material frame 10, thereby realizing automatic assembly and collection of the piston assembly.
