Description

Technical Field

[0001] The utility model relates to the technical field of valve stem processing equipment, in particular to an integrated equipment for valve stem O-ring assembly and detection. Background Technique

[0002] An O-ring is a rubber ring with a circular cross-section and has good sealing performance. It can be used for both static sealing and reciprocating motion sealing. It can be used alone and is also a basic component in many combined sealing devices. In valve design, the O-ring is usually installed outside the valve stem to fill the gap between the valve stem and the valve body to prevent fluid leakage from the valve stem.

[0003] During the production of valve stems, when an O-ring needs to be installed outside the valve stem, usually an operator manually picks up the O-ring from the storage device, then manually drives the O-ring to move, and finally the operator sleeves the O-ring on the outside of the valve stem in sequence to complete the assembly of the O-ring.

[0004] Currently, during the assembly of O-rings, although the O-ring can be manually handled and then sleeved on the outside of the valve stem in sequence, the efficiency of manual assembly is usually low, and the manual assembly speed and quality may be affected by the skills and experience of the workers. Moreover, due to the influence of the skills and experience of the workers on manual assembly, the consistency of the assembly results may be poor, and there may be differences in the assembly quality among different workers, which will ultimately affect the performance and reliability of the valve stem. Therefore, we propose an integrated equipment for valve stem O-ring assembly and detection. Content of the Utility Model

During the rising process, it touches the O-ring expanding and forming mechanism 306.

The height and width of the sealing ring feeding port are just enough for one sealing ring. After the sealing ring is in place, the O-ring in-place detection sensor 412 detects the sealing ring. At this time, the O-ring in-place detection sensor 412 transmits the detected data to the external control device in real time. After the material arrives, the external control device controls the cylinder piston of the material pushing cylinder 404 to extend through the external solenoid valve, thereby driving the O-ring to move upward.

[0035] The working principle of an integrated device for valve stem O-ring assembly and detection provided by the utility model is as follows: When starting to work, the external solenoid valve controls the telescopic end of the moving cylinder 516 to extend. At this time, the air gripper 505 is in the open state, and the valve stem is fed from the valve stem feeding vibrating disk 1 onto the valve stem slideway 510. When the valve stem in-place detection sensor 515 detects the valve stem, the valve stem feeding vibrating disk 1 stops feeding. At this time, the external solenoid valve controls the air gripper 505 to close, which also drives the valve stem gripper 506 to close. The valve stem gripper 506 clamps the valve stem through the V-shaped groove provided at its upper end. Then, the external solenoid valve controls the moving cylinder 516 to retract, driving the air gripper mounting plate 504 and the upper equipment to move, moving the valve stem from the left position to the right position. At this time, the external solenoid valve controls the air gripper 505 to release, and the external solenoid valve controls the moving cylinder 516 to drive the air gripper 505 to move back to its original position. By repeating this process, the valve stem is moved step by step. After each movement of the valve stem, O-ring assembly can be performed. During the process of loading the O-ring, the cylinder piston of the O-ring pushing cylinder 404 retracts, driving the O-ring feeding lifting platform 405 to the lower position. At this time, the sealed O-ring feeding vibrating disk 2 feeds, and the O-ring enters the sealing ring feeding port of the O-ring feeding lifting platform 405. The height and width of the sealing ring feeding port are just enough for one sealing ring. After the sealing ring is in place, the O-ring in-place detection sensor 412 detects the sealing ring. At this time, the O-ring in-place detection sensor 412 transmits the detected data to the external control device in real time. After the material arrives, the external control device controls the cylinder piston of the pushing cylinder 404 to extend through the external solenoid valve, driving the O-ring to move upward. After the O-ring reaches the upper position, the external solenoid valve controls the piston of the pushing cylinder 415 to drive the O-ring pushing plate 416 to move, so that the O-ring pushing plate 416 pushes out and drives the O-ring seal to the cross groove opened at the upper end of the fixed connecting plate 409. After reaching the position, the external solenoid valve controls the cylinder 402 to drive the floating joint 406 to move upward, and the floating joint 406 drives the sealing ring forming push rod 417 to rise, and the O-ring will be sleeved on the sealing ring forming push rod 417. During the rising process, it encounters the O-ring expanding and forming mechanism 306, and the O-ring expanding and forming mechanism 306 expands the O-ring and keeps the O-ring on the sealing ring forming push rod 417 waiting to be grabbed. The external solenoid valve controls the transverse sliding table cylinder 303 to drive the lifting cylinder 1 304 to move backward, and then the external solenoid valve controls the lifting cylinder 1 304 to drive the assembly mounting plate 305 to move downward, and the assembly mounting plate 305 drives the O-ring grasping finger 312 to move downward, and grabs the O-ring sleeved outside the sealing ring forming push rod 417 through the O-ring grasping finger 312. After grabbing the sealing ring, the external solenoid valve controls the lifting cylinder 1 304 to move upward to reset, and then controls the transverse sliding table cylinder 303 to drive the O-ring grasping finger 312 to move forward to reset through the external solenoid valve, so that the O-ring moves above the valve stem to be assembled. Then, the external solenoid valve controls the lifting cylinder 1 304 to drive the assembly mounting plate 305 to move downward.The assembly mounting plate 305 drives the assembly mounting plate 305 to move downward, and then drives the O-ring grasping finger 312 to move downward through the assembly mounting plate 305. The O-ring grasping finger 312 sleeves the valve stem through the O-ring. At this time, the external solenoid valve controls the lifting cylinder two 313 to drive the O-ring to disengage from the push plate 311 and move downward, so that the O-ring on the O-ring grasping finger 312 is pushed out and sleeved on the valve stem to complete the assembly. By adjusting the installation height of the O-ring grasping finger 312, the different installation heights of the two O-ring seals on the valve stem can be realized. After the assembly is completed, the O-ring presence / absence detection trigger piece 509 detects whether there is an O-ring. When there is no O-ring, the insertion depth is deeper, and when there is an O-ring, the insertion depth is shallower. After the processing is completed, if the detection is qualified, the material is directly pushed to the qualified material channel. If it is unqualified, the rejection cylinder 511 drives the rejection material channel 512 to extend, and the unqualified material is rejected into the unqualified material channel.
