Description

Technical Field

[0001] This invention relates to a hydraulic buffer assembly device, belonging to the field of intelligent manufacturing assembly technology. Background Technology

[0002] Hydraulic buffers rely on hydraulic damping to buffer and decelerate objects acting upon them until they stop, providing a certain degree of protection. They are suitable for lifting and transportation equipment, elevators, metallurgical machinery, port machinery, railway vehicles, and other mechanical equipment, serving as a safety buffer device to prevent damage to the mechanism from hard collisions during operation. A hydraulic buffer consists of a shell, nuts, and sealing rings, and requires a layer of grease to be applied to the outer surface of the telescopic shaft. Chinese invention patent CN202011103865.2 provides a hydraulic buffer assembly production system and its manufacturing process. It sequentially arranges a mandrel tightening device, a first retaining ring feeding device, a piston feeding device, a guide sleeve assembly feeding device, a second retaining ring feeding device, a limit nut feeding and tightening device, a reset valve feeding device, and a locking nut feeding and tightening device around a turntable assembly device, allowing these devices to operate simultaneously and improving assembly efficiency. Chinese invention patent with patent number CN201910024341.5 provides an automatic assembly equipment for piston components.

[0033] Based on this, a typical working process of the present invention is as follows:

[0034] When implementing this invention, as follows: Figure 1-9As shown, the outer shell vibration component 43 vibrates the outer shell of the hydraulic buffer sequentially to the positioning recess 421. The outer shell lateral movement cylinder 47 drives the outer shell gripping cylinder 49 to move forward along the outer shell track 44 to directly above the outer shell. The outer shell gripping cylinder 49 drives the expansion claw 411 to move downward to the inner cavity of the outer shell. The three-jaw clamping cylinder 410 drives the expansion claw 411 to open, expanding the outer shell from the inner cavity. The outer shell gripping cylinder 49 retracts, and then the outer shell lateral movement cylinder 47 retracts, transporting the outer shell to directly above the turntable component 3. The outer shell gripping cylinder 49 extends again, placing the outer shell into the outer shell fixture on the turntable component 3. The turntable component 3 rotates counterclockwise to the next station, namely the position of the nut feeding component 5. The nut feeding component 5 automatically feeds the nuts into the nut fixture on the turntable component 3. The turntable component 3 rotates counterclockwise to the next station, namely the position of the O-ring feeding component 6.

[0035] The O-ring vibratory feeder 64 vibrates the O-rings sequentially onto the O-ring positioning plate 63. The misalignment cylinder 62 drives the O-ring positioning plate 63 forward, positioning the O-rings directly below the initial opening claw 613. The O-ring pressing cylinder 610 drives both the initial opening claw 613 and the sleeve claw 615 downward simultaneously, causing the initial opening claw 613 to pass through the O-ring positioning plate 63, and the sleeve claw 615 to interlock and overlap with the secondary opening claw 620. At this point, the O-rings on the O-ring positioning plate 63 are guided by the initial guide chamfer 6132. The O-ring enters the surface of the initial expansion shaft 6131, completing the initial expansion of the O-ring's inner diameter; the O-ring pressing cylinder 610 retracts; the O-ring lateral movement cylinder 68 drives the O-ring pressing cylinder 610 to move forward along the O-ring guide rail 65; the O-ring pressing cylinder 610 extends, at which point the initial expansion claw 613 and the secondary expansion claw 620 overlap and insert, and the O-ring located on the surface of the initial expansion shaft 6131, under the push of the pressing external force, enters the surface of the secondary expansion shaft 6201 according to the guidance of the secondary guide chamfer 6202. At this point, the inner diameter of the O-ring is expanded a second time; the O-ring lateral movement cylinder 68 returns to its original position, and the O-ring pressing cylinder 610 extends, causing the initial opening claw 613 to pass through the O-ring positioning plate 63 again. The sleeve claw 615 and the secondary opening claw 620 interlock and overlap again. Under the action of the counter-thrust, the O-ring located on the surface of the secondary opening shaft 6201 enters the surface of the sleeve shaft 6151 along the sleeve guide chamfer 6152; the O-ring pressing cylinder 610 retracts, and the O-ring lateral movement cylinder 68 extends, so that the O-ring is just... Located directly above the nut position in turntable component 3, the O-ring pressing cylinder 610 extends again, causing the bottom surface of the nut head clearance groove 6155 to contact the upper end face of the nut. At this time, the O-ring groove on the surface of the nut shaft is just located on the lower end face of the collar shaft 6151. The disengagement cylinder 616 drives the release plate 617 to move downward. This process will push the O-ring downward on the surface of the collar shaft 6151 until it is disengaged from the surface of the collar shaft 6151. At this time, the O-ring is just pushed into the O-ring groove on the surface of the nut shaft, completing the loading and installation of the O-ring.

[0036] Turntable component 3 continues to rotate counterclockwise to the next station, and vision component 7 detects whether the nut is in the wrong position. Turntable component 3 continues to rotate counterclockwise to the next station, and nut flipping component 8 flips the nut 180° from its original position based on the detection result of vision component 7, thus meeting the conditions for locking the nut. Turntable component 3 continues to rotate counterclockwise to the next station. Nut locking and unloading component 9 first transports the nut with the O-ring in turntable component 3 to the upper end of the hydraulic buffer housing, and then uses an automatic screw fastening machine to tighten the nut and housing together. Simultaneously, the assembled outer shell nut is rotated 180° from the turntable component 3 and transported to the conveying component 10. At this time, the bottom cavity of the outer shell faces upward, and the end face of the nut contacts the conveyor belt surface. The conveying component 10 transports it to the transfer positioning clamp 1112 at the position of the oil filling weighing column component 1110. The transfer lifting cylinder 1111 lifts the outer shell nut upward. The vertical transport cylinder 116 first drives the transport clamping cylinder 118 to move upward, and the horizontal transport cylinder 114 then drives the vertical transport cylinder 116 to move horizontally. The linear guide 112 moves forward; the vertical transport cylinder 116 retracts, and the transport clamping cylinder 118 drives the transport gripper 119 to clamp the outer shell nut; the vertical transport cylinder 116 extends again, the horizontal transport cylinder 114 returns to its initial position, and the transport clamping cylinder 118 drives the transport gripper 119 to release, allowing the outer shell nut to be guided through the through hole on the surface of the outer shell guide plate 1117 and enter the positioning hole of the initial weighing sensor 1115. The initial weighing sensor 1115 weighs the outer shell nut at this moment; the vertical transport cylinder... Cylinder 116 and transverse transport cylinder 114 repeat their actions to transport the empty outer shell nut into the positioning hole of the secondary weighing sensor 1116. At this time, the oil injection telescopic cylinder 1118 drives the oil injector 1119 to move forward above the outer shell nut. The oil injector 1119 turns on the switch to inject grease into the inner cavity of the outer shell. After the secondary weighing sensor 1116 subtracts the weight of the primary weighing sensor 1115, it can display the weight of the injected grease in real time. After reaching the predetermined value, the PLC controls the oil injector 1119 to turn off, thus completing the grease injection.

[0037] The robotic arm component 13 moves the grease-filled outer shell nuts from the grease-filling and weighing component 11 to the position of the tray component 12. The tray component 12 places the outer shell nuts one by one onto the carrier and stacks the carriers layer by layer. At this point, the entire assembly process of the hydraulic buffer is completed.
