Description

Technical Field

[0001] This utility model belongs to the field of sealing ring assembly technology, and specifically relates to a device for assembling sealing rings. Background Technology

[0002] A sealing ring is a device used to prevent the leakage of liquids or gases. It is typically made of elastic materials and serves a sealing function. It plays a crucial role in various equipment and systems. Sealing rings are usually placed in grooves at the required locations on the product. To ensure a tight seal, the outer diameter of the sealing ring is usually slightly larger than the inner diameter of the sealing groove. For the installation of sealing rings in the internal grooves of mechanical devices, the sealing ring needs to undergo a certain deformation before it can be placed in the groove. However, currently, there is a lack of relevant sealing ring deformation mechanisms, so manual installation is usually used, resulting in low installation efficiency. Manual assembly is no longer suitable for the speed of modern industrial development. Therefore, developing a sealing ring assembly device to improve the automated assembly speed of sealing rings has become a technical problem that needs to be solved. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a sealing ring assembly device that can quickly and effectively deform the sealing ring. Combined with a robotic arm gripping and assembly mechanism, it enables automated assembly of the sealing ring, which can greatly improve the assembly efficiency of the sealing ring.

[0004] The objective of this utility model is achieved through the following technical solution:

The sealing ring deformation mechanism includes an operating table and a clamping auxiliary table located in the middle of the operating table. A set of deformation clamping plate assemblies for assisting the deformation of the sealing ring are symmetrically arranged on both sides of the clamping auxiliary table. The deformation clamping plate assemblies are connected to a drive mechanism located below the operating table. When the drive mechanism is working, it drives the deformation clamping plate assemblies to reciprocate towards each other. After the two deformation clamping plate assemblies move into position relative to each other, the inner shape formed by their sides is equivalent to the shape that the sealing ring needs to be deformed into.

[0006] Preferably, the deformable clamp assembly includes a clamp with an L-shaped cross-section, and a bulletproof plate is provided on the upper surface of the clamp.

[0009] Preferably, the gripping auxiliary platform is placed on the operating table via a spring in the middle, and the gripping auxiliary platform moves up and down on the operating table via the spring. The gripping auxiliary platform is provided with a slot.

[0010] Preferably, the diameter of the slot is approximately equal to the width of the gripper that holds the product.

[0023] This utility model proposes a device for assembling sealing rings. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description is provided in conjunction with the appendix. Figures 1-6 The present invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0024] A sealing ring assembly device includes a sealing ring deformation mechanism for assisting in deforming the sealing ring, and a sealing ring clamping and assembly mechanism for clamping and transferring the deformed sealing ring into a product for assembly.

[0025] The sealing ring deformation mechanism includes an operating table 1, a through hole in the middle of the operating table 1, and a clamping auxiliary table 2 below the through hole.

[0026] The clamping auxiliary platform 2 is positioned below the operating table surface via a central spring 21. When the clamping auxiliary platform 2 is pressed, it moves up and down relative to the operating table surface. The clamping auxiliary platform 2 has a slot 22. The diameter of the slot 22 is approximately equal to the width of the gripper claws used to clamp the product. Initially, after the sealing ring is gripped by the external device's claws and placed on the operating table surface, the claws engage with the slot 22 to determine the position of the sealing ring on the operating table surface. Since the sealing ring contains lubricating oil, an oil collection plate 6 is provided below the operating table surface 1 to prevent oil contamination caused by dripping from the through-hole after pressing the clamping auxiliary platform 2.

[0027] A set of deformation clamping plate assemblies for assisting the deformation of the sealing ring are symmetrically arranged on both sides of the through hole. The deformation clamping plate assemblies are connected to the drive mechanism 3 located below the operating table. When the drive mechanism 3 operates, it drives the deformation clamping plate assemblies to reciprocate towards each other. After the two deformation clamping plate assemblies move into position relative to each other, the inner shape formed is equivalent to the shape that the sealing ring needs to be deformed into. In this embodiment, the drive mechanism 3 is a gripper cylinder. The sealing ring 5 is placed on the operating table 1 of the gripping auxiliary table 2. When the gripper cylinder operates, it drives the deformation clamping plate assemblies on both sides of the gripping auxiliary table to move and squeeze the sealing ring 5 on the gripping auxiliary table 2 to deform it into the required shape.

[0028] The deformable clamp assembly includes an L-shaped clamp 4. A bulletproof plate 42 is provided on the upper surface of the clamp 4. The distal end of the bulletproof plate 42 protrudes from the distal end 43 of the clamp 4. The distance between the bottom of the bulletproof plate 42 and the operating table surface 1 is approximately equal to the height of the sealing ring 2. The bulletproof plate 42 is designed to prevent the sealing ring from being ejected from the clamp when it is compressed. The protruding bulletproof plate 42 presses the sealing ring under the bulletproof plate 42.

[0029] The clamping plate 4 has a limiting groove 44, which is an oblong groove and is axially arranged along the direction of movement of the clamping plate 4. The limiting groove 44 is fitted onto the limiting post 11 protruding from the operating table surface, and the clamping plate 4 reciprocates within the range of the limiting groove 44. To maintain the stability of the clamping plate 4 when moving on the operating table surface 1, a set of balance limiting plates 12 is fixedly installed on the operating table surface 1, and the two clamping plates 4 reciprocate between the balance limiting plates 12 along the axis of the balance limiting plates. Specifically, the outer sides of the longer plates of the two clamping plates 4 are locked into the balance limiting plates 12, and the shorter plates of the clamping plates 4 have protrusions 41 extending outward, while the inner side of the longer plate of the other clamping plate has a notch that mates with the protrusions 41, and the two are mutually engaged in a slotted manner. In this utility model, the two clamping plates are inserted into each other in pairs, and the outer side of the clamping plates is inserted into the balance limiting plate 12 to form a whole. The clamping and squeezing displacement between the clamping plates is limited by the length of the limiting groove 44.

[0030] The sealing ring clamping and assembly mechanism exemplified in this utility model includes a frame 7 placed on one side of the operating table 1. A rotating mechanism 72 is provided on one side of the frame 7, and the rotating mechanism 72 drives the frame 7 to rotate. In this embodiment, the rotating mechanism 72 is a quick-change disc, used in conjunction with a six-axis robot to realize the rotation of the sealing ring clamping and assembly mechanism. A drive cylinder 71 is provided above the frame 7, and a positioning gripper is also provided on the frame. The cylinder shaft of the drive cylinder 71 is connected to the sealing ring clamping assembly 73, and the positioning gripper is positioned directly above the sealing ring clamping assembly 73.

[0031] The sealing ring clamping assembly 73 includes a clamping upper plate 731 placed at the bottom of the substrate and a clamping lower plate 732 placed below the clamping upper plate 731. The clamping lower plate 732 is connected to the cylinder shaft of the driving cylinder 71. The bottom of the clamping upper plate 731 is machined with concave and convex textures to increase friction. When the driving cylinder 71 is working, it drives the clamping lower plate 732 to reciprocate towards the clamping upper plate 731, thereby clamping or releasing the product between the clamping upper plate and the clamping lower plate.

[0032] The following section describes the deformation and assembly of the sealing ring in conjunction with specific operational procedures.

[0033] The sealing ring 5 to be shaped is positioned by the grippers of an external device through the slot 22 on the gripping auxiliary table 2. After being placed on the operating table, it is removed. The sealing ring gripping assembly mechanism moves above the through hole, and the sealing ring gripping assembly 73 covers the through hole. The drive cylinder 71 works, causing the gripping lower plate 732 to move downwards and enter below the through hole, i.e., the sealing ring gripping assembly 73 is in the open state. At this time, the gripper cylinder works, causing the clamping plates to move towards each other. The distal end of the anti-bullet plate 42 on the clamping plate 4 first presses the two ends of the sealing ring to prevent it from popping up during subsequent compression. When the gripper cylinder continues to work, the inner side of the clamping plate will contact the sealing ring and apply pressure to it, causing the sealing ring to deform and squeeze the sealing ring between the gripping upper plate and the gripping lower plate. The drive cylinder works, causing the gripping lower plate 732 to move upwards and close with the gripping upper plate 731, keeping the deformed sealing ring clamped. The rotating mechanism operates, driving the frame to rotate to the position of the sealing ring product 8 to be installed. The sealing ring clamping assembly 73 extends into the inner cavity of the product 8. The inner cavity of the product 8 is provided with a groove 81. The diameter of the sealing ring clamping assembly 73 is smaller than the diameter of the groove 81. The clamping lower plate 732 opens under the operation of the driving cylinder. At this time, the clamped sealing ring 5 is released between the clamping upper plate and the clamping lower plate, thereby unfolding and entering the groove 81, completing the assembly of the product sealing ring.
