Abstract

This invention discloses an automatic rubber ring fitting device for valve bodies, comprising a conveyor belt, a retainer, a mounting base, a drive unit, a guide rod, and a movable plate. This automatic rubber ring fitting device for valve bodies uses a retainer on the conveyor belt to position the valve body, ensuring that the valve body's position does not shift or loosen. It works in conjunction with the guide rod to ensure the smooth downward movement of the rubber ring. The retainer not only positions the valve body but also prevents damage, facilitating easy insertion and removal by a robotic arm or operator. Furthermore, a first cylinder drives a second cylinder to move the guide rod, ensuring that the guide rod does not obstruct the valve body's movement. The cooperation between the second and first cylinders moves the rubber ring on the guide rod down onto the valve body, improving the efficiency of fitting the rubber ring onto the valve body.

Description

Technical Field

[0001] This invention relates to assembly technology, and more particularly to an automatic valve body ringing device. Background Technology

[0002] Before valve assembly, a rubber ring needs to be installed at the joint to ensure its sealing effect, thereby sealing the liquid or gas and preventing leakage. However, if the inner diameter of the rubber ring is equal to that of the joint, it will easily fall off. Therefore, the inner diameter of the rubber ring must be smaller than the diameter of the joint. This is achieved by fitting a rubber ring with an inner diameter smaller than the joint onto the joint, thus preventing it from falling off.

[0003] The reliance on semi-automation or traditional manual operation not only consumes a lot of time but also results in low production efficiency. If there are too many orders, production cannot keep up, causing irreparable losses to the company. Therefore, improvements are needed.

[0004] Before fitting the ring, it is necessary to ensure that the valve body is positioned so that it does not become loose or shifted, and at the same time, it is necessary to ensure that the valve body can be easily positioned and removed. Summary of the Invention

[0005] To address the shortcomings of the existing technology, this invention proposes an automatic valve body ringing device.

[0006] An automatic ringing device for valve bodies, comprising: A conveyor belt, wherein the conveyor belt is composed of multiple conveyor plates hinged together, and each conveyor plate is provided with a mounting hole; A retainer disposed within a mounting hole, the retainer being used to limit the position of the valve body; A mounting base that cooperates with a conveyor belt, the mounting base having a housing, a first cylinder inside the housing, a driving component on the first cylinder, the driving component extending to the outside of the housing, a second cylinder on the driving component, and symmetrically arranged clamping arms on the second cylinder; A movable plate is provided on the housing. The movable plate has a first sliding hole that cooperates with the driving component. A guide rod is provided on the movable plate. The guide rod has multiple rubber rings. The upper end of the guide rod is fixed to the movable plate by a positioning pin. The guide rod is located between symmetrically arranged clamping arms. The retainer has four evenly spaced elastic arms. The two sides of the elastic arms extend to form U-shaped segments. The elastic arms are connected to each other through the U-shaped segments. An L-shaped segment is provided between the U-shaped segments. The middle of the retainer forms a retaining area that mates with the mounting hole. The retainer pushes the elastic arm into the mounting hole from the lower end of the conveyor plate and keeps the elastic arm fixed to the upper end of the conveyor plate with bolts. When the first cylinder starts, the driving component simultaneously drives the movable plate and the second cylinder to move down. After the movable plate is blocked by the housing, the movable plate stops moving down. At this time, the second cylinder continues to move down, pushing the rubber ring on the guide rod onto the valve body.

[0007] In this invention, the elastic arm is provided with a mounting part, and a fixing hole is formed in the middle of the mounting part.

[0008] In this invention, after the elastic arm is bent and installed under force, it forms a movable segment, an arc-shaped segment, and a guide segment, and a compression area is formed between the movable segment and the guide segment.

[0009] In this invention, the middle of the L-shaped segment forms an insertion end, and the distance between the insertion ends is less than the width of the mounting hole.

[0010] In this invention, the driving component consists of a driving rod, a push plate, and a push rod. Both the driving rod and the push rod are connected to the push plate. The driving rod is connected to a first cylinder, and the push rod is connected to a second cylinder.

[0011] In this invention, the push rod is provided with a first limiting plate and a second limiting plate, and the movable plate is disposed between the first limiting plate and the second limiting plate.

[0012] In this invention, a spring is provided between the movable plate and the first limiting plate, and the spring is sleeved on the push rod.

[0013] In this invention, a notch is provided on one side of the housing, the movable rod is disposed in the notch, a cover plate is provided on the housing, a pin is provided on the cover plate and inserted into the notch, and a fifth sliding hole is provided on the movable plate to cooperate with the pin.

[0014] In this invention, the guide rod is composed of a first rod body and a second rod body, which are connected by a transition portion. The diameter of the second rod body is larger than that of the first rod body, and the upper end of the first rod body is provided with a tapered end.

[0015] In this invention, the clamping arm is provided with a semi-circular hole, a protrusion is formed in the middle of the semi-circular hole, the upper end of the protrusion forms an arc-shaped groove that mates with the rubber ring, and the lower end forms a receiving area that mates with the rubber ring.

[0016] The automatic valve body ring fitting device of this invention has the following advantages: By setting a retaining element on the conveyor belt, the device positions the valve body, ensuring that the valve body does not shift or loosen. It also works in conjunction with a guide rod to ensure the smooth downward movement of the rubber ring. The retaining element not only positions the valve body but also prevents damage, facilitating easy insertion and removal by a robotic arm or operator. Furthermore, the coordination of the first cylinder with the guide rod and the second cylinder ensures that the guide rod does not obstruct the movement of the valve body. Simultaneously, the cooperation between the second and first cylinders moves the rubber ring on the guide rod down onto the valve body, improving the efficiency of fitting the rubber ring onto the valve body.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] like Figures 1 to 11 As shown, this automatic valve body ringing device of the present invention includes a conveyor belt 1, a mounting base 2, a retainer 3, and a movable plate 4. The conveyor belt 1 is used to transport the valve body 5, and the valve body 5 is constrained on the conveyor belt 1 by the retainer 3, so that the valve body 5 remains stable during transport, while cooperating with the rubber ring 6 to complete the ringing.

[0021] The conveyor belt 1 is made up of multiple conveyor plates 7 hinged together. The conveyor plates 7 are connected by hinge shafts, which allows the conveyor plates 7 to be bent, thus facilitating the conveyor belt 1 to move in a bent state. A mounting hole 8 is provided on the conveyor plate 7, and threaded holes 10 that mate with bolts 9 are provided around the mounting hole 8 to fix the elastic arm 11 on the retainer 3.

[0022] A retainer 3 is disposed within the mounting hole 8 and is used to restrict the position of the valve body 5. The retainer 3 has four evenly distributed elastic arms 11, symmetrically arranged in pairs. U-shaped segments 12 extend from both sides of the elastic arms 11, with a first gap 13 formed in the middle of the U-shaped segments 12. The elastic arms 11 are connected to each other via the U-shaped segments 12. An L-shaped segment 14 is provided between the U-shaped segments 12, and the L-shaped segment 14 is connected to the U-shaped segment 12 via an arc-shaped portion 15. A second gap 16 is formed between the L-shaped segment 14 and the U-shaped segment 12. Through the cooperation of the first gap 13 and the second gap 16, the retainer 3 can easily maintain its torsion when deformed under force, thus facilitating its adaptation to the valve body 5 and restricting the position of the valve body 5.

[0023] The retainer 3 forms a retaining area 17 in the middle that mates with the mounting hole 8, and the valve body 5 is inserted into the retaining area 17. The retainer 3 pushes the elastic arm 11 into the mounting hole 8 from the lower end of the conveyor plate 7, and the retaining elastic arm 11 is fixed to the upper end of the conveyor plate 7 by bolts 9. When the retainer 3 is restricted to the lower end of the conveyor plate 7 by the elastic arm 11, the conveyor plate 7 is positioned exactly in the middle of the elastic arm 11, and the inner wall of the arc-shaped segment 18 on the elastic arm 11 maintains a certain distance from the inner wall of the mounting hole 8, so that when the valve body 5 is inserted into the mounting hole 8, it can push the elastic arm 11 to deform under force. Since the mounting part 19 on the elastic arm 11 remains stationary, the movable segment 20 on the elastic arm 11 continues to move downward, and the arc-shaped segment 18 squeezes the valve body 5, thereby restricting the valve body 5 within the mounting hole 8 by the elastic arm 11.

[0024] The elastic arm 11 is provided with a mounting part 19, and a fixing hole 21 is formed in the middle of the mounting part 19. The mounting part 19 is mounted on the conveyor plate 7 by bolts 9.

[0025] After the elastic arm 11 is bent under stress during installation, it forms a movable section 20, an arc-shaped section 18, and a guide section 22. A compression zone 23 is formed between the movable section 20 and the guide section 22. The movable section 20 is close to the U-shaped section 12, while the guide section 22 is close to the mounting part 19. Because the elastic arm 11 retains its deformation after installation, the mounting part 19, which was originally in the middle of the holding area 17, moves in the opposite direction to the upper end of the conveyor plate 7, thereby driving the guide section 22 into the mounting hole 8. When the valve body 5 is inserted into the mounting hole 8, it will first contact the guide section 22, and then maintain the entire elastic arm 11 under stress.

[0026] An insertion end 24 is formed in the middle of the L-shaped segment 14, and the distance between insertion ends 24 is less than the width of the mounting hole 8. Since the insertion end 24 extends to the middle of the holding area 17 and is located at the lower end of the mounting hole 8, when the valve body 5 is inserted into the mounting hole 8, it will push the insertion end 24 at the lower end, keeping the entire L-shaped segment 14 deformed and twisted downwards under force.

[0027] like Figure 9 As shown, when the valve body 5 is inserted downwards, the elastic arm 11 will be subjected to downward force in the direction of F1, while the L-shaped section 14 will be subjected to downward force and deformation in the direction of F2, causing the U-shaped section 12 and the arc-shaped part 15 to be twisted under force.

[0028] The valve body 5 is composed of a first connector 25, a first hexagonal part 26, a connecting part 27, a second hexagonal part 28, and a second connector 29 from top to bottom. The first connector 25 is provided with a first threaded part 30, and the second connector 29 is provided with a second threaded part 31. A sealing groove 32 that mates with the rubber ring 6 is formed on the first connector 25. The clamping arm 33 pushes the rubber ring 6 into the sealing groove 32.

[0029] Mounting base 2 cooperates with conveyor belt 1. Mounting base 2 is provided with housing 34. The interior of housing 34 is hollowed out to form installation area 35. A first cylinder 36 is provided inside housing 34. A driving component 37 is provided on the first cylinder 36. The driving component 37 extends to the outside of housing 34. A second cylinder 38 is provided on the driving component 37. A clamping arm 33 is symmetrically arranged on the second cylinder 38.

[0030] The clamping arm 33 has a semi-circular hole 39, with a protrusion 40 formed in the middle of the semi-circular hole 39. The upper end of the protrusion 40 forms an arc-shaped groove 41 that mates with the rubber ring 6, and the lower end forms a receiving area 42 that mates with the rubber ring 6. The clamping arm 33 can move the rubber ring 6 at the lowest point of the guide rod 43 downward. During the downward movement, the rubber ring 6 is restricted by the second rod 44 and deformed under force, increasing the inner and outer diameters of the rubber ring 6, thus passing over the second rod 44 and reaching the valve body 5.

[0031] The maximum diameter of its receiving area 42 is greater than the maximum diameter of the arc groove 41, which will increase the deformation of the rubber ring 6 within the receiving area 42, making it easier for the clamping arm 33 to push the deformed rubber ring 6 downward.

[0032] The movable plate 4 is mounted on the housing 34. The movable plate 4 has a first sliding hole 45 that cooperates with the driving component 37. The movable plate 4 has a guide rod 43 with multiple rubber rings 6. The upper end of the guide rod 43 is fixed to the movable plate 4 by a positioning pin 62. The guide rod 43 is located between the symmetrically arranged clamping arms 33.

[0033] The driving component 37 consists of a driving rod 53, a push plate 46, and a push rod 47. Both the driving rod 53 and the push rod 47 are connected to the push plate 46. The driving rod 53 is connected to the first cylinder 36, and the push rod 47 is connected to the second cylinder 38. The cover plate 48 is provided with a second sliding hole 49 that mates with the driving rod 53.

[0034] A first limiting plate 50 and a second limiting plate 51 are provided on the push rod 47, and a movable plate 4 is disposed between the first limiting plate 50 and the second limiting plate 51. The first limiting plate 50 is used to compress the spring 52, while the second limiting plate 51 is used to drive the movable plate 4 to move upward. The movable plate 4 is provided with a first sliding hole 45 that cooperates with the push rod 47.

[0035] A spring 52 is provided between the movable plate 4 and the first limiting plate 50, and the spring 52 is sleeved on the push rod 47. A notch 54 is provided on one side of the housing 34, and the movable plate 4 is disposed in the notch 54. A cover plate 48 is provided on the housing 34, and a pin 60 is provided on the cover plate 48 that is inserted into the notch 54. A fifth sliding hole 61 is provided on the movable plate 4 that cooperates with the pin 60.

[0036] The movable plate 4 can move up and down within the notch 54, thereby preventing the guide rod 43 from remaining stationary and causing the valve body 5 to be unable to move to the lower end of the guide rod 43.

[0037] Its guide rod 43 consists of a first rod body 56 and a second rod body 44, which are connected by a transition part 57. The diameter of the second rod body 44 is larger than that of the first rod body 56, and the upper end of the first rod body 56 is provided with a tapered end 58. The rubber ring 6 is fitted onto the first rod body 56 and then moves downward naturally under the influence of gravity, reaching the transition part 57. When the rubber ring 6 is pushed downward by the clamping arm 33, it is opened by the second rod body 44 and then reaches the first joint 25. The diameters of the first joint 25 and the second rod body 44 are matched, so that the rubber ring 6 is directly transitioned onto the first joint 25. When it continues to move downward, it will reach the sealing groove 32.

[0038] The movable plate 4 has a third sliding hole 59 that mates with the guide rod 43. The guide rod 43 is inserted into the third sliding hole 59, and then the position of the guide rod 43 is restricted by the positioning pin 62 inserted into the positioning hole 55. Of course, the guide rod 43 also has a positioning hole 55 that mates with the positioning pin 62.

[0039] When it is necessary to fit the rubber ring 6 onto the valve body 5, the valve body 5 to which the rubber ring 6 needs to be fitted can first be directly inserted into the mounting hole 8 by a robotic arm or by a worker. The valve body 5 is restricted in position by the retainer 3 located at the mounting hole 8, and then the elastic arm 11 clamps the valve body 5 in the middle. The insertion end 24 on its L-shaped section 14 will be kept tilted downward under the influence of the second threaded part 31, so that the insertion end 24 is inserted into the thread groove of the second threaded part 31. Thus, while the elastic arm 11 restricts the valve body 5, it keeps the position of the valve body 5 unchanged, providing a more stable positioning. The second hexagonal part 28 is directly placed on the surface of the elastic arm 11, preventing the valve body 5 from moving further downward. At the same time, it can also restrict the position of the valve body 5, so as to facilitate the alignment of the second rod 44 with the position of the valve body 5, and smoothly guide the downward movement of the rubber ring 6.

[0040] When the first cylinder 36 is activated, the drive unit 37 simultaneously moves the movable plate 4 and the second cylinder 38 downwards. The movable plate 4 moves downwards within the notch 54, while the second cylinder 38 moves the clamping arm 33 downwards, causing it to approach and move the rubber ring 6 at the bottom of the guide rod 43 downwards. Once the movable plate 4 is blocked by the housing 34 (i.e., blocked by the notch 54), its downward movement stops. At this point, the second cylinder 38 continues to move downwards, causing the first limit plate 50 to compress the spring 52. The guide rod 43 is now positioned at the top of the valve body 5. The clamping arm 33 pushes the rubber ring 6 on the guide rod 43 to fit onto the valve body 5.

[0041] like Figure 3 As shown, when the first cylinder 36 drives the drive component 37 to move downward, the position of the movable plate 4 will remain unchanged, while the push rod 47 will drive the second cylinder 38 to move downward, compressing the spring 52, and causing the clamping arm 33 on the second cylinder 38 to move closer, thus driving the rubber ring 6 to move downward.

[0042] And if Figure 3 At this point, when the first cylinder 36 drives the drive component 37 to move upward, the second limit plate 51 will drive the movable plate 4 to move upward, so that the second cylinder 38 and the movable plate 4 move upward synchronously, making it easier for the valve body 5 to be transported by the conveyor belt 1 to the lower end of the guide rod 43, while the valve body 5 with the rubber ring 6 already fitted is transferred to the lower position.

[0043] The clamping arm 33 on the second cylinder 38 can be freely controlled to keep it close or separate.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
