[0042] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0043] See attached Figure 1 As shown, a folding closed retaining ring installation mechanism in this embodiment includes a workbench 5, and also includes: a clamping device 1, a locking device 2, an insertion device 3 and a fixing device 4. The clamping device 1, the locking device 2, the insertion device 3 and the fixing device 4 are all fixedly connected to the workbench 5. The clamping device 1 is used to grasp and move the folding closed retaining ring 7, transfer the folding closed retaining ring 7 to the locking device 2 for locking, and then transfer the locked folding closed retaining ring 7 to the top of the fixing device 4 through the insertion device 3, and insert the folding closed retaining ring 7 into the workpiece 8 through the insertion mechanism.

[0044] In some embodiments, the gripper device 1 includes a first moving component 11 , a grabbing component 13 and a rotating component 12 , the first moving component 11 is connected to the workbench 5 , the grabbing component 13 is connected to the first moving component 11 , and the rotating component 12 is connected to the grabbing component 13 .

[0045] The grabbing assembly 13 includes a first fixed plate 131, a grabbing cylinder 132, a connecting rod 134 and a grabbing claw 133. The first fixed plate 131 is connected to the first movable assembly 11. The grabbing cylinder 132 and the grabbing claw 133 are connected by the connecting rod 134. The grabbing cylinder 132 can drive the grabbing claw 133 to clamp the folding closed retaining ring 7. Considering the stability and production cost of clamping, three grabbing claws 133 are provided in this embodiment.

[0046] The rotating assembly 12 includes a rotating drive member 121, a driving wheel 122, a driven wheel 123 and a transmission belt 124. The rotating drive member 121 is connected to the first fixed plate 131, and the output shaft of the rotating drive member 121 is connected to the driving wheel 122. When the rotating drive member 121 rotates, it drives the driving wheel 122 to rotate. The driven wheel 123 is sleeved on the connecting rod 134. The driving wheel 122 and the driven wheel 123 are connected by a transmission belt 124. When the driving wheel 122 rotates, the driven wheel 123 is driven to rotate through the transmission belt 124. The rotation of the driven wheel 123 drives the connecting rod 134 to rotate, and then drives the grabbing claw 133 to rotate, thereby driving the folding closed retaining ring 7 grabbed by the grabbing claw 133 to rotate, thereby changing the angle of the folding closed retaining ring 7.

[0047] The first moving assembly 11 includes a moving rail 111, a moving slider, and a moving cylinder. The moving rail 111 is connected to the workbench 5. The moving slider can move along the moving rail 111 under the action of the moving cylinder. Since the first fixed plate 131 is connected to the moving slider, the first fixed plate 131 moves under the drive of the moving slider, thereby driving the grabbing assembly 13 connected to the first fixed plate 131 to move. Therefore, during operation, after the grabbing assembly 13 grabs the folding and closing retaining ring 7, the first moving assembly 11 drives the grabbing assembly 13 to move above the locking device 2. During the movement, the folding and closing retaining ring 7 is photographed by the camera 6. If the position of the folding and closing retaining ring 7 deviates from the set position, the rotating assembly 12 drives the moving rod to rotate, thereby driving the folding and closing retaining ring 7 to rotate, so that the knot 71 of the folding and closing retaining ring 7 rotates to a predetermined position. The camera 6 is set on the workbench 5 and can capture the position of the knot 71 on the folding and closing retaining ring 7.

[0048] In some embodiments, the locking device 2 is fixedly connected to the workbench 5 and is used to tighten the retaining ring and reduce its diameter so that the folding closed retaining ring 7 can be installed in the workpiece 8. The locking device 2 includes a pneumatic clamping cylinder 21, a retaining ring driving push block 22, and a balancing roller 23. The pneumatic clamping cylinder 21 is arranged on the upper surface of the workbench 5. The pneumatic clamping cylinder 21 is provided with a plurality of pneumatic clamping jaws 211. In this embodiment, there are three pneumatic clamping jaws 211, but the number is not limited to three. The retaining ring driving push block 22 is connected to the pneumatic clamping jaws 211. The retaining ring driving push block 22 moves under the drive of the pneumatic clamping jaws 211. During the movement of the pneumatic clamping jaws 211, the retaining ring driving push block 22 radially squeezes the folding closed retaining ring 7. Since the folding closed retaining ring 7 is spiral, squeezing the folding closed retaining ring 7 can reduce its diameter to a set value. In addition, the balancing roller 23 is connected to the pneumatic clamp 211. During the squeezing process of the folding and closing retaining ring 7, the balancing roller 23 can drive the folding and closing retaining ring 7 to rotate, so that the outer surface of the folding and closing retaining ring 7 is evenly stressed during the squeezing process, preventing the folding and closing retaining ring 7 from being squeezed and deformed. The folding and closing retaining ring 7 still maintains its original shape, but only has a smaller diameter. After the folding and closing retaining ring 7 is compressed to a preset size, the next step is carried out through the insertion device 3.

[0049] In some embodiments, the insertion device 3 includes an insertion component 32 and a second movable component 31 . The second movable component 31 is connected to the workbench 5 . The insertion component 32 is connected to the second movable component 31 . The insertion component 32 is driven to move by the second movable component 31 .

[0050] The insertion component 32 includes an up and down adjustment component and an up and down insertion component 33.

The up and down adjustment cylinder 321 is connected to the up and down insertion component 33. The up and down adjustment cylinder 321 can drive the up and down insertion component 33 to move up and down.

[0051] The upper and lower insertion components 33 include a fixed frame 331, an insertion guide rail 323 is provided on the second fixed plate 322, an insertion slider 324 is provided on the insertion guide rail 323, the insertion slider 324 can move up and down along the insertion guide rail 323, the fixed frame 331 and the insertion slider 324 are connected, and the insertion slider 324 can drive the fixed frame 331 to move up and down, thereby driving the components connected to the fixed frame 331 through the fixed frame 331.

[0052] In some embodiments, the upper and lower insertion assemblies 33 include insertion jaws 334, an insertion rod 333, and an insertion cylinder 332. The insertion cylinder 332 is fixedly connected to the fixing frame 331, and the insertion rod 333 is connected to the insertion cylinder 332. The insertion cylinder 332 can drive the insertion rod 333 to move up and down. The insertion jaws 334 are connected to the fixing frame 331 and are disposed below the insertion rod 333. The insertion jaws 334 are used to clamp the necked folding and closing retaining ring 7 and move the folding and closing retaining ring 7 above the workpiece 8. The insertion rod 333 can pass through the gap between the insertion jaws 334 and push the folding and closing retaining ring 7 out of the insertion jaws 334 and into the workpiece 8.

[0053] In some embodiments, two insertion jaws 334 are provided, and the two insertion jaws 334 are arranged in a mirror image. A protrusion 3341 is provided below the insertion jaws 334, and a jaw through-slot 3342 is provided at an opposite position of the two protrusions 3341. The jaw through-slot 3342 is used to clamp the necked folding closed retaining ring 7. The shape of the protrusion 3341 is adapted to the internal structure of the workpiece 8 into which the folding closed retaining ring 7 is to be inserted. During operation, the folding closed retaining ring 7 is clamped through the jaw through-slot 3342, moved above the workpiece 8, and the protrusion 3341 is inserted into the workpiece 8. The insertion rod 333 is moved downward to push the folding closed retaining ring 7 out of the jaw through-slot 3342 and into the workpiece 8. Because the folding closed retaining ring 7 has an outward elastic force after being compressed, after the folding closed retaining ring 7 is pressed into the workpiece 8, the folding closed retaining ring 7 expands in diameter under the action of the elastic force, and fits the workpiece 8.

[0054] In some embodiments, the upper and lower insertion components 33 also include a clamping slider 335, which is connected to the insertion clamping jaw 334. A clamping jaw slide groove is provided on the fixed frame 331, and the clamping jaw slider 335 is provided in the clamping jaw slide groove.

[0055] In some embodiments, the fixing device 4 is arranged below the insertion component 32, and the insertion component 32 can move above the locking device 2 and the fixing device 4 under the drive of the second moving component 31. The fixing device 4 is connected to the workbench 5 and is arranged below the insertion component 32. The fixing device 4 includes a fixing seat 41 and a clamping component 42. The fixing seat 41 is provided with a groove 411. The shape of the groove 411 is adapted to the external shape of the workpiece 8. The workpiece 8 can be placed in the groove 411. The side wall of the groove 411 is provided with a first through hole 412. The clamping component 42 includes a clamping support seat 421, a clamping rod 422 and a clamping handle 423. The clamping support seat 421 is provided on a side of the fixing seat 41 close to the first through hole 412. The support seat is provided with a clamping through hole. The clamping rod 422 passes through the clamping through hole and the first through hole 412 on the fixing seat 41, and abuts against the workpiece 8 through one end of the clamping rod 422, thereby fixing the workpiece 8. A waist-shaped groove 4211 is provided on the support seat, and the waist-shaped groove 4211 is connected to the clamping through hole. A clamping handle 423 is provided on the clamping rod 422, and the clamping handle 423 passes through the waist-shaped groove 4211. The position of the clamping rod 422 can be changed by pushing and pulling the clamping handle 423. A second through hole 4212 is provided on the support seat, and the second through hole 4212 is connected to the waist-shaped groove 4211. When the clamping handle 423 is pushed to make the clamping rod 422 clamp and fix the workpiece 8, the clamping handle 423 is pushed into the second through hole 4212 to fix the clamping handle 423, and then the clamping rod 422 is fixed.

[0056] In some embodiments, the fixing device 4 also includes a limit seat 43, which is arranged on the side of the fixing seat 41 away from the clamping assembly 42, and the limit seat 43 is arranged below the fixing frame 331. When the upper and lower adjustment components adjust the position of the insertion assembly 32, when the fixing frame 331 and the limit seat 43 are in contact with each other, the position is at an optimal height. At the same time, an elastic member is provided on the limit seat 43. When the fixing frame 331 and the limit seat 43 are in contact with each other, it plays a buffering role to prevent the fixing frame 331 and the limit seat 43 from colliding and reducing the service life of the equipment.

A groove 411 is provided inside the fixing seat 41. The shape of the groove 411 is adapted to the external shape of the workpiece 8. The workpiece 8 can be placed in the groove 411. The side wall of the groove 411 is provided with a first through hole 412; the clamping component 42 includes a clamping support seat 421, a clamping rod 422 and a clamping handle 423. The clamping support seat 421 is provided on the side of the fixing seat 41 close to the first through hole 412. A clamping through hole is provided on the support seat. The clamping rod 422 passes through the clamping through hole and the first through hole 412 on the fixing seat 41, and the workpiece 8 is fixed by abutting one end of the clamping rod 422 against the workpiece 8. A waist-shaped groove 4211 is provided on the support seat, and the waist-shaped groove 4211 is connected to the clamping through hole. A clamping handle 423 is provided on the clamping rod 422, and the clamping handle 423 passes through the waist-shaped groove 4211. The position of the clamping rod 422 can be changed by pushing and pulling the clamping handle 423. A second through hole 4212 is provided on the support seat, and the second through hole 4212 is connected to the waist-shaped groove 4211. When the clamping handle 423 is pushed to make the clamping rod 422 clamp and fix the workpiece 8, the clamping handle 423 is pushed into the second through hole 4212 to fix the clamping handle 423, and then the clamping rod is fixed.

[0072] Working process: The grabbing assembly 13 grabs the folding closed retaining ring 7, and is driven by the first moving assembly 11 to move to the top of the locking device 2. During the movement, the camera 6 takes a picture of the folding closed retaining ring 7. When it is found that the position of the knot 71 of the folding closed retaining ring 7 is offset, the grabbing assembly 13 is driven to rotate by the rotating assembly 12, thereby correcting the position of the knot 71 of the folding closed retaining ring 7. When the folding closed retaining ring 7 is moved to the locking device 2 through the clamping jaw device 1, the folding closed retaining ring 7 is limited by the clamping jaw cylinder 21. After being limited, the folding closed retaining ring 7 is grabbed by the clamping jaw slot 3342, and then moved to the top of the fixing device 4 through the first moving assembly 11. The protrusion 3341 of the insertion jaw 334 is inserted into the workpiece 8 by the up and down adjustment cylinder 321, and then the insertion rod 333 moves downward to push the folding closed retaining ring 7 out of the clamping jaw slot 3342 and into the workpiece 8. Since the folding closed retaining ring 7 has an outward elastic force after being compressed, after the folding closed retaining ring 7 is pressed into the interior of the workpiece 8, the diameter of the folding closed retaining ring 7 is expanded under the action of the elastic force, and the folding closed retaining ring 7 and the interior of the workpiece 8 are in contact with each other.
