Description

Technical Field

[0001] The utility model relates to the field of stainless steel bellows, in particular to automatic assembly equipment for stainless steel bellows plugging covers. Background Art

[0002] Stainless steel bellows is a flexible pressure-resistant pipe installed in a liquid delivery system, which can play a connecting role. In order to facilitate connection, the end of the stainless steel bellows is provided with a union nut for connection. Since the union nut of the stainless steel bellows is a connecting component, its sealing is particularly important. A rubber gasket needs to be installed in the union nut to play a sealing role. Before the stainless steel bellows is used for connection, the stainless steel bellows exists alone, so external dust and impurities can easily enter the stainless steel bellows through the union nut of the stainless steel bellows. In order to avoid this situation, a matching plug cap will be screwed into the union nut. At the same time, the plug cap can detect whether there is an internal thread in the union nut, to avoid the situation where the stainless steel bellows cannot be used to connect other devices due to the missing internal thread in the union nut.

[0003] To sum up, it can be known that the stainless steel bellows needs to be installed with gaskets and plugging covers in the later stage, and the installation work is generally done manually. The staff first inserts the gasket into the union nut of the stainless steel bellows, and then screws the plugging cover into the union nut. The staff needs to repeat these two assembly actions for a long time, and the staff's physical strength will gradually be exhausted in the continuous assembly work. The assembly efficiency of the staff will gradually decrease, resulting in the overall assembly efficiency being limited, and movement deviations are very likely to occur during manual assembly. The installation position of the gasket can be adjusted after it is incorrect, but if the plugging cover is eccentric when screwed, the external thread of the outer wall of the plugging cover and the internal thread of the inner wall of the union nut will bite each other, causing the internal thread of the inner wall of the union nut to wear, affecting the service life of the union nut. Summary of the invention

[0004] The utility model aims to solve the existing technical problem and provide an automatic assembly device for stainless steel corrugated pipe plugging covers, which can not only always maintain high assembly efficiency, but also effectively ensure assembly quality, avoid the situation where the external threads of the outer wall of the plugging cover and the internal threads of the inner wall of the union nut are bitten and worn due to eccentricity when the plugging cover is screwed, and effectively prolong the service life of the union nut.

[0038] A lower left guide hole 59 coaxial with the piston rod of the fifth cylinder 44 is provided on the lower surface of the left slider 38; a lower left seat plate 72 is provided on the rear side wall of the lower end of the motor mounting plate 40; and a lower left guide rod 60 matching the lower left guide hole 59 is provided on the upper surface of the lower left seat plate 72.

[0039] The rotating mechanism also includes a rotating motor 61 arranged at the center of the lower inner wall of the rotating chamber 4; the upper end of the motor shaft of the rotating motor 61 is connected to a rotating shaft 63 through a coupling 62, and the rotating disk 6 is arranged at the upper end of the rotating shaft 63; the lower inner wall of the rotating chamber 4 is provided with a guide inner tube 64 set outside the rotating motor 61; the lower surface of the rotating disk 6 is provided with a guide outer tube 65 coaxial with the guide inner tube 64, and the lower end of the guide outer tube 65 is sleeved outside the guide inner tube 64.

[0040] A rib 66 with a U-shaped cross section extends downward from the lower edge of the hanging groove 7 .

[0041] The method of using the utility model is as follows:

[0042] The four circumferentially evenly distributed suspension grooves 7 on the rotating disk 6 are respectively located at the front, rear, left and right sides of the rotating disk 6 in the initial state, and the angle formed between adjacent suspension grooves 7 is 90 degrees. Therefore, when the assembly work starts, the rotating disk 6 will rotate 90 degrees each time under the action of the rotating motor 61. After completing one process, it will rotate another 90 degrees, and the cycle will be repeated to achieve the effect of continuously assembling the gasket 68 and the plugging cover 69 of the stainless steel bellows 67.

[0043] When it is necessary to assemble the stainless steel bellows 67 with the gasket 68 and the plugging cover 69, first put the union nut 6701 at the upper end of the stainless steel bellows 67 into the hanging groove 7. At this time, the union nut 6701 is stuck on the upper surface of the hanging step 8, and the outer wall of the union nut 6701 is a regular hexagon. One side corner of the union nut 6701 just fits with the positioning angle 9 of the rear side groove wall of the hanging groove 7. Under the action of the hanging step 8 and the positioning angle 9, the union nut 6701 can be stably restricted in the hanging groove 7, so that the union nut 6701 cannot rotate under the action of external force, which is convenient for the plugging cover 69 to be screwed into the union nut 6701 later.

[0044] When the plugging cover automatic assembly equipment is started, the gasket vibration plate 3 and the plugging cover vibration plate 2 both start to run. The gasket vibration plate 3 and the plugging cover vibration plate 2 are both existing vibration plates, which can realize the feeding of gaskets 68 and plugging covers 69 by vibration force. When the gasket vibration plate 3 is used, the gaskets 68 in the gasket vibration plate 3 will be fed to the gasket feeding trough 29 in an orderly manner along the feeding track 301 of the gasket vibration plate 3 under the action of the vibration force. At this time, the first gasket 68 will enter the gasket feeding trough 29 under the push of the subsequent gaskets 68, and continue to go deeper into the gasket feeding trough In the groove 29, the gasket 68 is annular, and a tubular sealing portion 6801 extends downward from the edge of the lower end of the inner hole of the gasket 68. At this time, the sealing portion 6801 is located between the guide wings 30 on both sides, and the gasket 68 is located between the upper side groove wall of the gasket feeding groove 29 and the upper surface of the guide wings 30. This structural design can ensure that the gasket 68 can move stably after entering the gasket feeding groove 29. With the push of subsequent gaskets 68, the first gasket 68 is finally restricted by the left side groove wall of the gasket feeding groove 29. At this time, the first gasket 68 is directly below the insertion port 71.

[0045] When the first gasket 68 is directly below the insertion port 71 and the insertion rod 26 is directly above the insertion port 71, when the gasket 68 needs to be assembled, the second cylinder 21 can be started. When the right slider 16 cannot move up and down, as the piston rod of the second cylinder 21 is retracted into the second cylinder 21, the second cylinder mounting plate 20 will move downward accordingly, thereby realizing the downward movement of the insertion rod 26 arranged at the center of the lower end surface of the right guide plate 18. As the insertion rod 26 continues to move downward, the insertion rod 26 will enter the gasket feeding groove 29 through the insertion port 71, and then be directly inserted into the inner hole of the gasket 68. The gasket is made of rubber. At this time, the insertion rod 26 can be inserted through its outer wall and the gasket The friction force between the inner walls of 68 fixes the gasket 68 on the lower end of the insertion rod 26, and then the piston rod of the second cylinder 21 will push downward to realize the upward movement of the right guide plate 18, thereby realizing the upward movement of the gasket 68 fixed on the lower end of the insertion rod 26. When the gasket 68 moves to the actual required height, the second cylinder 21 stops running, and the first cylinder 15 starts to start. The piston rod of the first cylinder 15 drives the right slider 16 along the trajectory of the right slide rail 17 to approach the hanging groove 7 on the right side of the rotating disk 6. When the right slider 16 moves, the insertion rod 26 with the gasket 68 on the lower end moves synchronously, and finally moves to the top of the hanging groove 7 on the right side of the rotating disk 6.

[0046] When the plugging cover vibration plate 2 is running, the multiple plugging covers 69 on the plugging cover vibration plate 2 will be transported in an orderly manner along the feeding track 201 toward the plugging cover feeding hole 47 under the action of the vibration force. As the first plugging cover 69 enters the plugging cover feeding hole 47, the first plugging cover 69 will be restricted by the limiting plate 48, so that the first plugging cover 69 is stably located between the front moving groove 50 and the rear moving groove 49, avoiding the situation that the first plugging cover 69 is pushed by the subsequent plugging cover 69 and causes the position to be offset. Then the sixth cylinder 53 can be started. At this time, the piston rod of the sixth cylinder 53 will push the push block 55 forward. As the push block 55 moves forward, the push block 55 will push the first blocking cover 69 into the front moving groove 50. Under the restriction of the front groove wall of the front moving groove 50, the first blocking cover 69 is just on the upper surface of the support plate 58. When the push block 55 pushes the first blocking cover 69, as the push block 55 enters from the rear moving groove 49 into the blocking cover feed hole 47, the subsequent blocking cover 69 can be effectively retained in the feeding track 201 of the blocking cover vibration plate 2, thereby achieving a material blocking effect.

[0047] As the union nut 6701 at the upper end of the stainless steel bellows 67 is stuck in the hanging groove 7 on the front side of the rotating disk 6, the rotating motor 61 can be turned on by the touch switch to make the rotating motor 61 rotate for the first time. When the rotating motor 61 rotates, the motor shaft of the rotating motor 61 will drive the rotating shaft 63 to rotate 90 degrees, thereby realizing a 90-degree rotation of the rotating disk 6. When the original front side hanging groove 7 on the rotating disk 6 rotates to the right, the original left side hanging groove 7 on the rotating disk 6 rotates to the front side. At this moment, the staff can clamp a new union nut 6701 at the upper end of the stainless steel bellows 67 in the hanging groove 7 on the front side of the rotating disk 6 at this moment, and the union nut 6701 stuck in the hanging groove 7 on the right side of the rotating disk 6 at this moment can start to assemble the gasket 68. At this moment, the union nut 6701 is directly below the insertion rod 26, and then the second cylinder 21 is started. Under the action of the second cylinder 21, the insertion rod 26 moves downward with the gasket 68 sleeved on its lower end, and finally the gasket is The gasket 68 will enter into the union nut 6701 and fit with the annular step 6702 in the union nut 6701. At this time, the insertion rod 26 stops moving downward, and then the third cylinder 22 is started at the same time. The piston rod of the third cylinder 22 drives the lifting plate 23 to move downward, thereby realizing the downward movement of the ejector tube 25. When the insertion rod 26 does not move, the ejector tube 25 moves downward alone. When the lower end surface of the ejector tube 25 contacts the upper surface of the gasket 68, the lower end of the ejector tube 25 presses the gasket 68 onto the union nut. On the annular step 6702 inside the cap 6701, the ejector tube 25 is then kept stationary, and the insert rod 26 moves upward under the action of the second cylinder 21. When the gasket 68 is pressed and immobilized by the ejector tube 25, the insert rod 26 can easily overcome the friction between its own outer wall and the inner wall of the gasket 68 and break away from the inner hole of the gasket 68. Finally, the ejector tube 25 moves upward under the action of the third cylinder 22 and moves out of the union nut 6701, and finally the gasket 68 is assembled in the union nut 6701.

[0048] To facilitate understanding of the hanging order of each hanging slot 7 on the rotating disk 6, the first four hanging slots 7 on the rotating disk 6 are respectively defined as the first hanging slot, the second hanging slot, the third hanging slot, and the fourth hanging slot. In the initial state, the first hanging slot is at the front side of the rotating disk, the second hanging slot is at the right side of the rotating disk, the third hanging slot is at the back side of the rotating disk, and the fourth hanging slot is at the left side of the rotating disk. First, the movable nut 6701 at the upper end of the stainless steel bellows 67 can be stuck in the first hanging slot, and then the rotating motor 61 is rotated for the first time, 90 degrees counterclockwise. After the rotating motor 61 rotates the rotating disk 6 ninety degrees, the first hanging slot is at the right side of the rotating disk, and the gasket assembly device installs the gasket 68 into the movable nut at the upper end of the stainless steel bellows stuck in the first hanging slot. At this moment, the fourth hanging slot is at the front side of the rotating disk 6, and a new stainless steel bellows can be placed in it. After the stainless steel bellows 67 in the first hanging groove completes the assembly work of the gasket 68, the rotating disk 6 is rotated 90 degrees counterclockwise again under the action of the rotating motor 61. At this time, the fourth hanging groove is on the right side of the rotating disk 6, and the first hanging groove is on the rear side of the rotating disk 6, and the third hanging groove is on the front side of the rotating disk 6. Then the new stainless steel bellows 67 can be inserted into the third hanging groove. After the stainless steel bellows 67 in the fourth hanging groove completes the assembly work of the gasket, the rotating disk 6 is rotated 90 degrees counterclockwise again under the action of the rotating motor 61. At this time, the first hanging groove is on the left side of the rotating disk 6 for the assembly work of the plugging cover 69, and the fourth hanging groove is on the rear side of the rotating disk 6, waiting for the assembly work of the plugging cover 69, and the third hanging groove is on the right side of the rotating disk 6 for the assembly work of the gasket 68, and the second hanging groove is on the front side of the rotating disk 6, and a new stainless steel bellows can be placed.

[0049] When the movable nut 6701 at the upper end of the stainless steel bellows 67 in the first hanging groove is assembling the plugging cover 69, the pneumatic finger 42 is just in the upper top hole 51, and at this moment the plugging cover 69 is just pushed out of the upper top hole 51 by the supporting plate 58. As the fifth cylinder 44 is opened, the piston rod of the fifth cylinder 44 will retract into itself, thereby realizing the downward movement of the fifth cylinder mounting plate 43, thereby realizing the downward movement of the motor mounting plate 40, and finally realizing the downward movement of the pneumatic finger 42. The existing cylindrical pneumatic clamping jaws adopted by the pneumatic finger 42 are convenient for the pneumatic finger 42 to clamp the plugging cover 69. The center of the lower surface of the plugging cover 69 has a screw connection portion 6901 screwed into the movable nut 6701. When the pneumatic finger 42 clamps the plugging cover 69, the pneumatic finger 42 is clamped on the outer peripheral surface of the plugging cover 69, which will not affect the screw connection action of the screw connection portion 6901. After the pneumatic finger 42 clamps the plugging cover 69 , under the action of the fifth cylinder 44, the pneumatic finger 42 moves up, and when it moves to the actual required position, the fourth cylinder 37 is started, and the piston rod of the fourth cylinder 37 will drive the left slider 38 along the trajectory of the left slide rail 39 to the right close to the first suspension groove. When the pneumatic finger 42 moves synchronously to just above the first suspension groove, the fourth cylinder 37 stops running, and then the fifth cylinder 44 and the tightening motor 41 run synchronously. While the fifth cylinder 44 drives the pneumatic finger 42 to move downward, the tightening motor 41 drives the pneumatic finger 42 to rotate, thereby realizing the synchronous downward movement and rotation of the blocking cover 69, and quickly screwing the blocking cover 69 into the joint nut 6701. Under the limitation of the positioning angle 9, the joint nut 6701 will not be affected by the rotation force of the blocking cover 69, and the joint nut 6701 can always remain in a stable state. When the blocking cover 69 is screwed, the pneumatic finger 42 moves up and resets.

[0050] When the union nut 6701 of the stainless steel bellows 67 in the first hanging groove completes the assembly work of the plugging cover 69, the rotating disk 6 rotates 90 degrees again under the action of the rotating motor 61. At this time, the first hanging groove is at the front side of the rotating disk 6. The staff can remove the stainless steel bellows 67 on the first hanging groove that has completed the assembly work of the gasket 68 and the plugging cover 69, and install a new stainless steel bellows 67. When the new stainless steel bellows 67 is hung on the first hanging groove, the stainless steel bellows 67 on the second hanging groove is at the right side of the rotating disk 6. The assembly work of the gasket begins, the stainless steel bellows 67 on the third hanging groove rotates to the rear side of the rotating disk 6, the stainless steel bellows 67 on the fourth hanging groove rotates to the left side of the rotating disk 6, and the assembly work of the plugging cover 69 begins. When the stainless steel bellows 67 on the fourth hanging groove completes the assembly of the plugging cover 69, the rotating disk 6 is rotated 90 degrees counterclockwise again under the action of the rotating motor 61 to start a new round of assembly work. This cycle is repeated to ensure that the stainless steel bellows 67 is always used to assemble the gasket 68 and the plugging cover 69 without being affected by loading and unloading.

[0051] In summary, the utility model can realize equal-angle rotation of the rotating disk 6 through the rotating mechanism, and each rotation of the rotating disk 6 can complete a corresponding process, so that the movable nut 6701 of the stainless steel bellows 67 is always in a working state of sequentially assembling the gasket 68 and the plugging cover 69 after being stuck on the hanging groove 7, so as to always maintain high working efficiency, and the direct participation of the staff in the assembly work of the gasket 68 and the plugging cover 69 is effectively avoided in the entire assembly process, thereby avoiding the situation where the assembly quality cannot be guaranteed due to manual assembly, and the tightening action of the plugging cover 69 is realized by the rotational force of the tightening motor 41, which can effectively avoid the eccentricity when the plugging cover 69 is screwed, resulting in the external thread of the outer wall of the plugging cover 69 and the internal thread of the inner wall of the movable nut 6701 biting and wearing, thereby effectively extending the service life of the movable nut 6701.

[0052] The width of the observation port 31 is smaller than the width of the insertion port 71. This structural design can not only firmly confine the gasket 68 in the gasket feed slot 29, but also can observe the state of the gasket in the gasket feed slot 29 in real time through the observation port 31, so as to timely discover the abnormality of the gasket 68 and facilitate the assembly of the gasket 68.

[0053] A lower right guide hole 32 coaxial with the piston rod of the second cylinder 21 is provided on the lower surface of the right slider 16, and a lower right guide rod 33 matching the lower right guide hole 32 is provided on the upper surface of the lower positioning plate 19. The existence of the lower right guide rod 33 can play a guiding role when the right guide plate 18 moves up and down, thereby ensuring the stability of the gasket assembly device when assembling the gasket.

[0054] A lower left guide hole 59 is provided on the lower surface of the left slider 38 and is coaxial with the piston rod of the fifth cylinder 44. A lower left seat plate 72 is provided on the rear side wall of the lower end of the motor mounting plate 40. A lower left guide rod 60 matching the lower left guide hole 59 is provided on the upper surface of the lower left seat plate 72. The existence of the lower left guide rod 60 can play a guiding role when the motor mounting plate 40 moves up and down, thereby ensuring the stability of the blocking cover assembly device when assembling the blocking cover 69, and further avoiding the blocking cover 69 from tilting when it is screwed to the joint nut 6701 of the stainless steel bellows 67.

[0055] A guide inner tube 64 is provided on the inner wall of the lower side of the rotating chamber 4 and is arranged outside the rotating motor 61. A guide outer tube 65 is provided on the lower surface of the rotating disk 6 and is coaxial with the guide inner tube 64. The lower end of the guide outer tube 65 is sleeved outside the guide inner tube 64. The existence of the guide inner tube 64 can guide the guide outer tube 65 when it rotates with the rotating disk 6, thereby guiding the rotating disk 6 and further ensuring the stability of the rotating disk 6 when it rotates with the stainless steel bellows 67.

[0056] A U-shaped rib 66 extends downward from the edge of the lower groove of the suspension groove 7. The rib 66 can enclose the upper part of the stainless steel bellows 67 when the joint nut 6701 at the upper end of the stainless steel bellows 67 is stuck in the suspension groove 7, thereby playing a protective and limiting role.

[0057] A connecting plate 70 can be set at the upper end of the rotating shaft 63. The connecting plate 70 and the rotating disk 6, the rotating disk 6 and the upper end surface of the guide outer tube 65, and the rotating motor 61 and the lower inner wall of the rotating chamber 4 are all fixed by screws. This fixing method is convenient for disassembly and assembly of components, thereby facilitating maintenance and replacement of components.
