Description

Technical Field

[0001] This invention relates to the field of pressure relief valve processing equipment technology, specifically to a loading and assembly module for plunger O-ring springs. Background Technology

[0002] The relief valve contains many internal components, such as plungers, plunger O-rings, springs, transformer paper, and the housing. The automated assembly of the relief valve involves assembling these components, a process divided into multiple steps, each assembling different components. Currently, the assembly of the plunger, plunger O-rings, and springs still requires manual labor in relief valve manufacturing workshops. This process is relatively cumbersome and inefficient, failing to meet the demands of large-scale production assembly. Therefore, we propose a plunger O-ring and spring loading and assembly module.

A double-rod cylinder 12 for driving the vertical support part 2 to move horizontally is provided at the center of the base plate 11.

[0061] It should be added that the first guide slide rail is composed of a first slide rail fixing plate 14, a first slide rail 15, and a first linear slider 22.

[0062] In a preferred embodiment, the vertical support part 2 includes a base plate 21, on which two symmetrical side plates 23 are fixedly mounted.

The second linear slider 213 can move freely on the second slide rail 25. The two are matched and configured to cooperate with each other. Through the matching sliding configuration of the second linear slider 213 and the second slide rail 25, it can be ensured that the slider fixing plate 212 always moves linearly without deviation.

[0064] Furthermore, the second guide rail section also includes a third rail fixing plate 210 and a slider fixing plate 212 fixed thereto. The slider fixing plate 212 is slidably disposed on the guide plate 29, and the third rail fixing plate 210 and the guide plate 29 do not contact each other.

[0065] It should be added that the lead screw part consists of a servo motor 26, a lead screw 27, and a lead screw slider 28.

The lead screw slider 28 is fixed to the slider fixing plate 212. The servo motor 26 can drive the lead screw 27 to rotate, thereby driving the lead screw slider 28 to move, and in turn driving the slider fixing plate 212 and the third slide rail fixing plate 210 to move.

[0066] As a preferred embodiment, the vertical support 2 further includes a guide plate 29 fixed between the two side plates 23, and the vertical moving part 3 is slidably disposed on the guide plate 29.

[0067] As a preferred embodiment, the vertical moving part 3 includes a mounting plate 31, on which a second connecting block 32 is provided. The end of the second connecting block 32 is provided on the vertical support part 2. Specifically, the end of the second connecting block 32 is fixed on the third slide rail fixing plate 210, and a lowering cylinder 33 capable of driving the entire vertical moving part 3 to move up and down is also installed on the second connecting block 32. The piston rod of the lowering cylinder 33 passes through the second connecting block 32 and is fixed to the mounting plate 31.

[0068] It should be added that a third guide rail section is provided between the mounting plate 31 and the third slide rail fixing plate 210.

[0069] Specifically, the third guide slide rail consists of a third linear slider 34 and a third slide rail 211. The third linear slider 34 is fixed on the mounting plate 31, and the third slide rail 211 is fixed on the third slide rail fixing plate 210. The third linear slider 34 can move freely along the third slide rail 211. The two are matched and configured to ensure that the mounting plate 31 always moves linearly without deviation.

[0070] As a preferred embodiment, a plurality of second grippers 35 are mounted on the mounting plate 31. Each second gripper 35 consists of two gripping arms and a pneumatic source capable of driving the two gripping arms to move synchronously toward each other.

[0071] First, the double-rod cylinder 12 is activated to push the base plate 21 to move horizontally. At the same time, the servo motor 26 can be activated to drive the lead screw 27 to rotate, thereby driving the lead screw slider 28 to move horizontally, which in turn drives the slider fixing plate 212 and the slide rail fixing plate 210 to move, thereby driving the entire vertical moving part 3 to move horizontally. Then, the lowering cylinder 33 is activated to push the mounting plate 31 to move up and down, thereby driving the second gripper 35 on it to move up and down. Through the above process, the second gripper 35 can be pushed to accurately reach the position of the plunger and accurately grip the plunger. After gripping, the plunger can be transferred to the next process by the horizontal movement of the vertical moving part 3.

[0072] In practical use, the plunger is placed inside the storage box 511 of the plunger vibrating feeding part 51. The vibration motor 512 of the plunger vibrating feeding part 51 is started to drive the storage box 511 to vibrate, so that the plunger inside slowly moves down along the arc-shaped feeding track 513 and enters the plunger feeding plate 52. After passing through the plunger feeding plate 52, it reaches the first bearing seat 56. The plunger detection camera 59 detects the plunger and controls the first cylinder 54 and the first motor 55 to start. The first cylinder 54 pushes the first top column 57 to move upward, pushing the first motor 55 and the plunger on the first bearing seat 56 to move upward, so that it reaches the position corresponding to the second gripper 35. The second gripper 35 accurately grips the plunger. After gripping, the plunger can be transferred to the next process by the horizontal movement of the vertical moving part 3.

[0073] Meanwhile, the springs are placed into the storage box 511 on the spring vibrating feeding section 61. The vibration motor 512 on the spring vibrating feeding section 61 is started to drive the storage box 511 to vibrate, causing the springs inside to slowly move down along the arc-shaped feeding track 513 and enter the spring feeding groove 621. Since the spring feeding groove 621 is an inclined rectangular shape and matches the shape of the springs, the springs will be neatly arranged and enter the spring feeding groove 621 in sequence. Then they reach the spring transfer section 65 and enter the transfer groove 655 on the transfer plate 654. The spring detection camera 64 detects the springs and controls the rotary motor 652 to start, driving the transfer plate 654 and the springs on it to rotate to the vertical direction. The piston rod of the downward pressing cylinder 663 moves down through the piston rod through hole 665 and presses the inclined surface 6611 of the two clamping arms 668, causing the two clamping arms 668 to unfold. When the clamping arms 668 contact the spring, the piston rod of the downward pressing cylinder 663 moves up. Under the action of the return spring, the clamping arms 668 return to their original position and clamp the spring. Then, the second cylinder 661 is activated to move up, driving the spring to move up. Then, the first pushing cylinder 673 is activated to push the first guide seat 674 to move, thereby pushing the spring clamping part 66 and pushing the spring to the middle placement seat 82. The spring is then spliced ​​together with the plunger held by the second clamping claw 35. After splicing, the second clamping claw 35 is used to clamp and transfer the spring to the next placement seat 82.

[0074] Simultaneously, the O-rings are placed into the storage bin 511 on the O-ring vibrating feeding section 71. The vibration motor 512 on the O-ring vibrating feeding section 71 is started, driving the storage bin 511 to vibrate. This causes the O-rings inside to slowly move down along the arc-shaped feeding track 513 and enter the O-ring feeding plate 72. After passing through the O-ring feeding plate 72, they enter the placement table 734. Then, the lifting cylinder 732 is started to push the placement table 734 and the O-rings on it upward. Next, the gripper cylinder 753 is started to open the three first grippers 754 and use the three second grippers... The clamping jaw 754 holds the O-ring with its clamping flap 756. Then, the electric cylinder 751 is activated to move the O-ring upward. The second pushing cylinder 743 is activated to push the second guide seat 744 and the electric cylinder 751 to move, pushing the O-ring onto the placement seat 82. The O-ring is then placed on the plunger picked up by the second clamping jaw 35, completing the assembly between the plunger, spring and O-ring. The whole process can realize the automatic feeding and assembly of the plunger, spring and O-ring on the pressure relief valve. The whole process does not require manual operation and can achieve a relatively ideal working efficiency.
