Therefore, it brings great strength to the assembly operation and cannot realize automatic delivery of the sealing ring during assembly. Summary of the invention

[0019] Beneficial effects of the present invention:

[0020] 1. The present invention has multiple placement units, which can continuously assemble sealing rings for batches of manifolds. The transposition unit can be used to transpose multiple branch disks to the bottom of the assembly unit, so that the assembly unit can assemble the sealing rings for the manifolds placed on the branch disks. The delivery unit can automatically feed the sealing rings to supplement the arc plates on the assembly unit. There is no need to manually set the sealing rings on the multiple arc plates, and the tops of the multiple arc plates are arranged with bevel edges, which can guide the fallen sealing rings to avoid the sealing rings from offsetting and falling when they fall on the multiple arc plates. The assembly unit can also expand the arc rings that fall on the outside of the multiple arc plates after internal support, so that the sealing rings remain in a taut state. At this time, the inside of the sealing ring can be evenly immersed in oil with the oil immersion unit. By immersing the inside of the sealing ring in oil so that it can be installed on the manifold, the wear during assembly can be reduced, an initial lubricating film can be formed to ensure subsequent sealing performance, and the sealing ring can also be prevented from getting stuck.

[0021] 2. The present invention soaks the sealing ring in oil when it is stretched on the arc plate. Compared with the existing device, the sealing ring is uniformly soaked in oil and then salvaged for assembly. This can effectively avoid long-term contact with the outside world during soaking and salvaging, which may cause impurities inside the sealing ring. At the same time, since the sealing ring is in a tight and stretched state on the arc plate, the inside of the sealing ring can be evenly soaked in oil, reducing the waste of lubricating oil. The stretched sealing ring can be dragged and moved downward on the arc plate through the stretching and pressing unit, so that it can be quickly mounted on the manifold to complete the assembly with the manifold.

[0022] 3. The present invention adopts the arrangement of arc frames, so that when a plurality of arc plates approach or move away from the central tube, every two adjacent arc frames can rotate, and the telescopic plates can be extended and retracted in coordination therewith, so that the spray box always moves along with the arc plates. While satisfying the need to install sealing rings on manifolds of different specifications and sizes, the inside of the manifolds can also be immersed in oil according to the sealing rings of different sizes.

[0023] 4. The present invention drives the stretching rod to rotate by turning on the motor. When the stretching rod rotates, it is located on the inner wall of the sealing ring and remains perpendicular to the existing ground. At this time, the electric slider is turned on to drive the mounting frame to move downward in the sliding groove until the multiple arc plates are docked with the outside of the manifold. The electric push plate is then controlled to retract. When the electric push plate retracts, the sealing ring is stretched and tightened. Then the electric slider is turned on to drive the connecting frame to move downward. When the connecting frame moves downward, the sealing ring is moved downward on the multiple arc plates through the lower side of the electric push plate, and finally the sealing ring is sleeved on the manifold.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] As attached Figure 1-9 As shown, an automobile manifold sealing ring assembly device includes a double-layer base 1, a central turntable 11 is rotatably installed in the middle of the upper side of the double-layer base 1, a plurality of circumferentially arranged branch disks 12 are arranged on the central turntable 11, a transposition unit for position conversion of the plurality of branch disks 12 is arranged below the central turntable 11, a placement unit for fixing the manifold is arranged in the middle of the upper end surface of the branch disk 12, a vertical plate 41 is fixedly installed on one side of the double-layer base 1, movable grooves 42 are opened on both sides of the vertical plate 41, mounting frames 43 are slidably installed in the movable grooves 42 through electric sliders, a delivery unit for automatically delivering the sealing ring during assembly is commonly installed between the mounting frames 43 on both sides, an assembly unit is detachably installed on the inner wall of the delivery unit, a stretching and pressing unit connected to the delivery unit is arranged outside the assembly unit, and an oil immersion unit for oiling the inner wall of the sealing ring is arranged in the stretching and pressing unit.

[0038] As attached Figure 2As shown, the placement unit is set up in multiple ways, which can continuously assemble the sealing rings for batches of manifolds. Through the setting of the transposition unit, multiple branch disks 12 can be transposed to the bottom of the assembly unit, so that the assembly unit can assemble the sealing rings for the manifolds placed on the branch disk 12. Through the setting of the delivery unit, the sealing rings can be automatically unloaded to supplement the arc plates 62 on the assembly unit. There is no need to manually set the sealing rings on the multiple arc plates 62, and the tops of the multiple arc plates 62 are set with bevel edges, which can guide the fallen sealing rings to avoid the sealing rings from offsetting and falling when they fall on the multiple arc plates 62. The setting of the assembly unit can also expand the arc rings that fall on the outside of the multiple arc plates 62 after internal support, so that the sealing rings remain in a taut state. At this time, the oil immersion The unit can evenly immerse the inside of the sealing ring in oil. By immersing the inside of the sealing ring in oil so that it can be installed on the manifold, the wear during assembly can be reduced, an initial lubricating film can be formed to ensure the subsequent sealing performance, and the sealing ring can be prevented from getting stuck. The present invention immerses the sealing ring in oil when it is stretched on the arc plate 62. Compared with the existing device, the sealing rings are uniformly immersed in oil and then salvaged for assembly. This can effectively avoid long-term contact with the outside world during immersion and salvage, which may cause impurities inside the sealing ring. At the same time, since the sealing ring is in a tight and stretched state on the arc plate 62, the inside of the sealing ring can be evenly immersed in oil, reducing the waste of lubricating oil. The stretched sealing ring can be dragged downward on the arc plate 62 by the stretching and pressing unit, so that it can be quickly mounted on the manifold to complete the assembly with the manifold.

[0039] As attached Figure 3 As shown, the transposition unit includes an intermittent wheel 21, and a plurality of circumferentially arranged driving grooves 22 are provided at the outer edge of the intermittent wheel 21. The plurality of driving grooves 22 correspond one to one with the plurality of branch disks 12 respectively. A driving rod 23 rotatably connected to the double-layer base 1 through a motor is provided on one side of the intermittent wheel 21. A rotating frame 24 is fixedly mounted on one end of the driving rod 23, and a toggle column 25 is fixedly mounted on the side of the upper end surface of the rotating frame 24 away from the driving rod 23.

[0040] When multiple manifolds are replaced in order to carry out continuous assembly operations on manifolds that have not been installed with sealing rings, the motor is turned on to drive the drive rod 23 to rotate. When the drive rod 23 rotates, the rotating frame 24 and the toggle column 25 are synchronously driven to rotate along the axis of the drive rod 23. When the toggle column 25 rotates, the drive groove 22 is toggled in turn, thereby changing the position of the branch disk 12 on the central turntable 11, so that the manifolds on the multiple branch disks 12 are rotated to the bottom of the assembly unit in turn, so that the sealing rings can be installed on the manifolds.

[0041] As attached Figure 5As shown, the placement unit includes a plurality of rectangular grooves 31 circumferentially formed on the branch disk 12. A moving plate 32 arranged in an inverted L shape is slidably installed in the rectangular groove 31. A screw rod 33 is rotatably installed on the upper end surface of the moving plate 32 through a motor. A U-shaped frame 34 fixed to the moving plate 32 is arranged on one side of the screw rod 33. A clamping plate 35 that is threadedly rotatably installed on the screw rod 33 and slides in the U-shaped frame 34 is provided. A ring is formed between the plurality of clamping plates 35 for surrounding and erecting the manifold when installing the sealing ring on the manifold.

[0042] As shown in the appendix Figure 4 As shown, a cylinder 36 is fixedly installed on one side of the lower end surface of the branch disk 12. A toothed plate 37 is fixedly installed at the telescopic end of the cylinder 36. A rotating wheel 38 installed at the center of the branch disk 12 is arranged on one side of the toothed plate 37. A control disk 39 located above the branch disk 12 is fixedly installed on the coaxial of the rotating wheel 38. A plurality of lower plates 323 respectively fixed to the plurality of moving plates 32 are arranged below the control disk 39. A plurality of push-pull grooves 390 are formed on the control disk 39. A fixed column 324 that slides in the push-pull groove 390 is fixedly installed on the lower plate 323. A middle groove 321 is formed in the middle of the moving plate 32. A T-shaped plate 322 is installed in the middle groove 321 through a spring. One end of the T-shaped plate 322 penetrates and slides in the moving plate 32. A placing plate for placing the bottom of the manifold when assembling the sealing ring on the manifold is fixedly installed at one end of the T-shaped plate 322.

[0043] When assembling the sealing ring on the manifold, it is necessary to keep the manifold stable. At this time, the cylinder 36 is started to push forward. When the cylinder 36 pushes forward, the rotating wheel 38 is driven to rotate through the toothed plate 37. When the rotating wheel 38 rotates, the control disk 39 is synchronously driven to rotate. When the control disk 39 rotates, the fixed column 324 is driven to move through the push-pull groove 390. At this time, the plurality of moving plates 32 approach each other in the rectangular groove 31, so that the clamping plates 35 clamp the outer wall of the manifold, and the arrangement between the plurality of T-shaped plates 322 can be made to approach each other through the setting of the spring, and the plurality of placing plates can承接 the bottom of the manifold.

[0044] As shown in the appendix Figure 6 As shown, the feeding unit includes a storage cylinder 51. An outer ring 52 is installed around the outer wall of the storage cylinder 51. A rotating rod 54 is rotatably installed on one side of the outer ring 52 through a motor. A side groove 53 is formed on one side of the storage cylinder 51 close to the rotating rod 54. A lower supporting plate 56 is fixedly installed at the lower end of the rotating rod 54. An upper supporting plate 55 fixed to the rotating rod 54 is arranged above the lower supporting plate 56. The arrangement between the upper supporting plate 55 and the lower supporting plate 56 is opposite, and alternately discharges the sealing rings in the storage cylinder 51.

[0045] When the sealing rings in the reserve cylinder 51 are automatically replenished on the multiple arc plates 62, the motor is turned on to drive the rotating rod 54 to rotate. When the rotating rod 54 rotates, it synchronously drives the upper support plate 55 and the lower support plate 56 to rotate synchronously. Since the upper support plate 55 and the lower support plate 56 are arranged in opposite directions, the sealing ring between the upper support plate 55 and the lower support plate 56 can fall when the lower support plate 56 rotates. At this time, the upper support plate 55 supports the sealing ring that is about to fall, thereby completing the sealing ring assembly. Compared with the existing device, after the sealing ring and the manifold on the arc plate 62 are installed, the present invention can automatically replenish the sealing ring on the arc plate 62 without the need for workers to replenish it. When the sealing ring falls, since the multiple bevel plates 621 are arranged with bevel edges, the sealing ring can accurately fall to the outer edges of the multiple bevel plates 621. At this time, the stretching and pressing unit can press the sealing ring down to the outer edges of the multiple spray ports 622 for wrapping, so as to subsequently carry out oil immersion operations on the inner wall of the sealing ring.

[0046] As attached Figure 6 , 7 As shown, the assembly unit includes a central tube 6, and a plurality of circumferentially arranged sliding plates 61 are slidably installed on the inner wall of the central tube 6, and springs fixed to the inner wall of the central tube 6 are fixedly installed on both sides of the sliding plates 61, and an arc plate 62 is fixedly installed on one side away from the plurality of sliding plates 61, and a bevel plate 621 is fixedly installed on the top of the arc plate 62, and a spray port 622 is opened on the bevel plate 621, and a center rod 63 is installed in the middle of the central tube 6 through rotation of a motor, and a plurality of cams 64 are fixedly installed in the middle of the center rod 63.

[0047] The motor is turned on to drive the center rod 63 to rotate, and when the center rod 63 rotates, the multiple cams 64 are driven to rotate synchronously. When the cams 64 rotate, the sliding plate 61 is squeezed. After being squeezed, the multiple sliding plates 61 slide outward, and at this time, the multiple arc plates 62 are driven away from each other to tighten and open the sealing ring. By adjusting the spacing between the multiple arc plates 62, the inner walls between the multiple arc plates 62 can fit the outside of the manifold below, so that the sealing ring can be quickly put on the manifold when it is pressed down and dragged.

[0048] As attached Figure 7 As shown, the oil immersion unit includes arc frames 71 rotatably mounted on both sides of the arc plate 62, a telescopic plate 72 fixed to the central tube 6 is provided between every two adjacent arc frames 71, a built-in column 75 is fixedly installed on one side of the two arc frames 71, a spray box 76 is fixedly installed on the front side of the telescopic plate 72, a limiting plate 73 is fixedly installed on the lower end of the spray box 76, limiting grooves 74 are opened on both sides of the limiting plate 73, and the limiting grooves 74 on both sides are respectively sleeved on the outside of the built-in columns 75 on both sides, and a delivery pipe is commonly connected between the two sides of the spray box 76 and the spray ports 622 on the arc plates 62 on both sides.

[0049] By setting the arc frame 71, when multiple arc plates 62 approach or move away from the central tube 6, every two adjacent arc frames 71 can rotate, and the telescopic plate 72 can be extended and retracted in coordination therewith, so that the spray box 76 always moves along with the arc plate 62. While satisfying the need to install sealing rings on manifolds of different specifications and sizes, the inside of the manifold can also be immersed in oil according to the sealing rings of different sizes.

[0050] As attached Figure 5 As shown, the stretching and pressing unit includes an outer groove 511 annularly opened on the storage tube 51, a vertically arranged stabilizing rod 512 is fixedly installed in the outer groove 511, a connecting frame 513 is sleeved on the outside of the stabilizing rod 512 and is slidably connected to the outer groove 511 through an electric slider, an electric push plate 514 is fixedly installed at the bottom of the connecting frame 513, a U-shaped groove 515 is opened at the telescopic end of the electric push plate 514, and a stretching rod 516 is installed in the U-shaped groove 515 through the rotation of a motor.

[0051] The motor is turned on to drive the stretching rod 516 to rotate. When the stretching rod 516 rotates, it is located on the inner wall of the sealing ring and remains perpendicular to the existing ground. At this time, the electric slider is turned on to drive the mounting frame 43 to move downward in the sliding groove 42 until the multiple arc plates 62 are docked with the outside of the manifold. Then the electric push plate 514 is controlled to retract. When the electric push plate 514 retracts, the sealing ring is stretched and tightened. Then the electric slider is turned on to drive the connecting frame 513 to move downward. When the connecting frame 513 moves downward, the sealing ring is moved downward on the multiple arc plates 62 through the lower side of the electric push plate 514, and finally the sealing ring is set on the manifold.

[0052] The spray box 76 can be set to immerse the inner wall of the sealing ring sleeved outside the plurality of arc plates 62 in oil, and the use of spraying can avoid waste of oil immersion, and the spray port 622 cooperates with the spray box 76 to evenly and fully immerse the inner wall of the sealing ring in oil.

[0053] The stretching and pressing unit can press the sealing ring installed on the outside of the arc plate 62 downward, and the lower end of the arc plate 62 is longer than the lower part of the center tube 6, so that the center tube 6 is abutted against the top of the manifold. At this time, the downward pressure of the stretching and pressing unit can quickly put the sealing ring on the outside of the arc plate 62 on the manifold.

[0054] When in use, the placement unit is set as multiple settings, which can continuously assemble the sealing rings of batches of manifolds. Through the setting of the transposition unit, multiple branch disks 12 can be transposed to the bottom of the assembly unit, so that the assembly unit can assemble the sealing rings of the manifolds placed on the branch disk 12. Through the setting of the delivery unit, the sealing rings can be automatically unloaded to supplement the arc plates 62 on the assembly unit. There is no need to manually set the sealing rings on the multiple arc plates 62, and the tops of the multiple arc plates 62 are set with bevel edges, which can guide the fallen sealing rings to avoid the sealing rings from offsetting and falling when they fall on the multiple arc plates 62. The setting of the assembly unit can also expand the arc rings that fall on the outside of the multiple arc plates 62 after internal support, so that the sealing rings remain in a taut state. At this time, the immersion The oil unit can evenly immerse the inside of the sealing ring in oil. By immersing the inside of the sealing ring in oil so that it can be installed on the manifold, the wear during assembly can be reduced, an initial lubricating film can be formed to ensure the subsequent sealing performance, and the sealing ring can also be prevented from getting stuck. The present invention immerses the sealing ring in oil when it is stretched on the arc plate 62. Compared with the existing device, the sealing ring is uniformly immersed in oil and then salvaged for assembly. This can effectively avoid long-term contact with the outside world during immersion and salvage, which causes impurities inside the sealing ring. At the same time, since the sealing ring is in a tight and stretched state on the arc plate 62, the inside of the sealing ring can be evenly immersed in oil, reducing the waste of lubricating oil. The stretched sealing ring can be dragged down on the arc plate 62 by the stretching and pressing unit, so that it can be quickly sleeved on the manifold to complete the assembly with the manifold.

[0055] When multiple manifolds are replaced so as to continuously assemble the manifolds that have not been installed with sealing rings, the motor is turned on to drive the driving rod 23 to rotate. When the driving rod 23 rotates, the rotating frame 24 and the toggle column 25 are synchronously driven to rotate along the axis of the driving rod 23. When the toggle column 25 rotates, the driving groove 22 is sequentially toggled, thereby switching the position of the branch disk 12 on the central turntable 11, so that the manifolds on the multiple branch disks 12 are sequentially rotated to the bottom of the assembly unit, so as to assemble the sealing ring on the manifold and seal the manifold. When assembling the ring, the manifold needs to be kept stable. At this time, the cylinder 36 is turned on and pushed forward. When the cylinder 36 is pushed forward, the rotating wheel 38 is driven to rotate through the tooth plate 37. When the rotating wheel 38 rotates, the control disk 39 is driven to rotate synchronously. When the control disk 39 rotates, the fixed column 324 is driven to move through the push-pull groove 390. At this time, the multiple moving plates 32 are close to each other in the rectangular groove 31, so that the clamping plate 35 clamps the outer wall of the manifold, and the multiple T-shaped plates 322 can be close to each other through the setting of the spring, and the multiple supporting plates can be supported on the bottom of the manifold;

[0056] When the sealing rings in the reserve cylinder 51 are automatically replenished on the multiple arc plates 62, the motor is turned on to drive the rotating rod 54 to rotate. When the rotating rod 54 rotates, it synchronously drives the upper support plate 55 and the lower support plate 56 to rotate synchronously. Since the upper support plate 55 and the lower support plate 56 are arranged in opposite directions, the sealing ring between the upper support plate 55 and the lower support plate 56 can fall when the lower support plate 56 rotates. At this time, the upper support plate 55 supports the sealing ring that is about to fall, thereby completing the sealing ring assembly. Compared with the existing device, after the sealing ring and the manifold on the arc plate 62 are installed, the present invention can automatically replenish the sealing ring on the arc plate 62 without workers replenishing it. When the sealing ring falls, since the multiple bevel plates 621 are arranged in a beveled manner, the sealing ring can accurately fall to the outer edge of the multiple bevel plates 621. At this time, the stretching and pressing unit can press the sealing ring down to the outer edge of the multiple spray ports 622 for wrapping, so as to subsequently perform oil immersion on the inner wall of the sealing ring;

[0057] The motor is turned on to drive the center rod 63 to rotate. When the center rod 63 rotates, it simultaneously drives multiple cams 64 to rotate. When the cam 64 rotates, it squeezes the sliding plate 61. After being squeezed, multiple sliding plates 61 slide outward, and at this time drive multiple arc plates 62 to move away from each other, so as to tighten and open the sealing ring. By adjusting the spacing between the multiple arc plates 62, the inner walls between the multiple arc plates 62 can fit the outside of the manifold below, so that the sealing ring can be quickly put on the manifold when it is pressed and dragged. Through the setting of the arc frame 71, when the multiple arc plates 62 approach or move away from the center tube 6, every two adjacent arc frames 71 can rotate, and the telescopic plate 72 cooperates with it to expand and contract, so that the spray box 76 always follows the arc plate 62 is moved, and while satisfying the need to install sealing rings on manifolds of different specifications and sizes, it is also possible to immerse the inside of sealing rings of different sizes in oil. The motor is turned on to drive the stretching rod 516 to rotate. When the stretching rod 516 rotates, it is located on the inner wall of the sealing ring and remains vertical to the existing ground. At this time, the electric slider is turned on to drive the mounting frame 43 to move downward in the sliding groove 42 until the multiple arc plates 62 are docked with the outside of the manifold, and then the electric push plate 514 is controlled to retract. When the electric push plate 514 retracts, the sealing ring is stretched and tightened. Then the electric slider is turned on to drive the connecting frame 513 to move downward. When the connecting frame 513 moves downward, the sealing ring is moved downward on the multiple arc plates 62 through the lower side of the electric push plate 514, and finally the sealing ring is sleeved on the manifold.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
