[0035] The following further describes the usage method of the utility model in conjunction with the drawings and specific embodiments.

[0036] As Figures 1 to 6 shown, a steel ring clamping device for sleeving the steel ring 2 on the cylinder body 5 includes:

[0037] A tooling platform 1 for placing the steel ring 2 and the cylinder body 5;

[0038] It further includes:

[0039] A centering mechanism 3 for clamping and centering the steel ring 2. The centering mechanism 3 includes:

[0040] A push ring 31 provided on the top of the tooling platform 1. The push ring 31 is provided with a plurality of driving holes 311;

[0041] A first driving oil cylinder 32 provided on the tooling platform 1. The first driving oil cylinder 32 is used to drive the push ring 31 to rotate;

[0042] A plurality of bases 33 are arranged in a circular array on the top of the tooling platform 1 with the axis of the push ring 31 as the center. Each base 33 is respectively provided with a plurality of guiding grooves 333, and each guiding groove 333 extends along the radial direction of the push ring 31;

[0043] A plurality of push rods 34. Each push rod 34 is slidably arranged in a guiding groove 333 and extends into a driving hole 311. When the push ring 31 rotates, the hole wall of the driving hole 311 pushes the push rod 34 to move, and the guiding groove 333 restricts the push rod 34 to move along the radial direction of the push ring 31 and clamps and centers the steel ring 2;

[0044] A guiding mechanism 4. The guiding mechanism 4 is used to clamp the cylinder body 5 so that the steel ring 2 can be sleeved on the outer side of the cylinder body 5. The guiding mechanism 4 includes:

[0045] A plurality of second driving oil cylinders 42; the second driving oil cylinders 42 are used to drive the guiding wheels 44 to move.

[0046] A plurality of guiding wheels 44 are respectively arranged corresponding to the second driving oil cylinders 42. Under the drive of the second driving oil cylinders 42, the plurality of guiding wheels 44 press the cylinder body 5 to sleeve the steel ring 2 on the outer side of the cylinder body 5.

[0047] Multiple groups of guiding mechanisms 4 are evenly distributed around the tooling platform 1. The front-end guiding wheels 44 extend out to form a circle with a diameter of D. The inner diameter of the steel ring 2 > D > the outer diameter of the cylinder body 5. When the front-end guiding wheels 44 retract, they also form a circle with a diameter of D'. D' > the outer diameter of the steel ring 2; This optimizes the effect and quality of the steel ring 2 being sleeved on the cylinder body 5, and at the same time reduces the manual participation and improves the automation degree of the equipment.

[0048] The tooling platform 1 is of a circular ring structure, and a plurality of sliding holes 11 perpendicular to the diameter are opened on the tooling platform 1. And opening a plurality of sliding holes 11 perpendicular to the diameter is to ensure that the push ring 31 above it can rotate.

[0049] The first driving oil cylinder 32 is connected to the bottom of the pushing ring 31 through a connecting block 321. The connecting block 321 is located inside the sliding hole 11 and can slide inside the slider. When the two first driving oil cylinders 32 are started simultaneously, the connecting block 321 will be pushed to move inside the sliding hole 11, driving the pushing ring 31 at the top to rotate a certain angle, thereby driving the push rod 34 on the base 33 to move radially inward.

[0050] Two first roller bearings 331 are provided on both sides of the guiding groove 333 of the base 33, and the push rod 34 is located between the two first roller bearings 331. The base 33 is located above the pushing ring 31. The first roller bearings 331 are used to reduce the friction between the push rod 34 and the guiding groove 333, enabling the push rod 34 to move quickly and clamp and center the steel ring 2. At the same time, it can also reduce the wear between the guiding groove 333 and the push rod 34 and increase its service life.

[0051] A plurality of pressing strips 332 are provided on the top of the base 33. The pressing strips 332 are located above the guiding groove 333. The pressing strips 332 are used to limit the movement of the push rod 34, and the pressing strips 332 are located between the first roller bearings 331 at both ends of the base 33. When the push rod 34 is moving and comes into contact with and clamps the steel ring 2, the pressing strips 332 will limit the upward movement of the push rod 34 during the movement, thus ensuring the stability of the movement of the push rod 34.

[0052] A bolt 341 is provided on the top of the push rod 34, and the bolt 341 is located between the two pressing strips 332. The bolt 341 is used to limit the moving distance of the push rod 34. At the same time, it can also limit the push rod 34 and restrict the radial movement of the push rod 34.

[0053] The second driving oil cylinder 42 is fixed to the tooling platform 1 through an oil cylinder seat 41.

[0054] The oil cylinder seat 41 slidably penetrates a guide rod 43. The guide rod 43 is connected to the guide wheel 44 through a support plate 45. The guide rod 43 is used to limit the horizontal offset of the guide wheel 44 during the pushing process of the second driving oil cylinder 42. In order to ensure that the guide wheel 44 does not shift after contacting the cylinder body 5, it is necessary to limit it through the guide rod 43 to prevent the guide wheel 44 from shifting horizontally during the forward movement.

[0055] The push rod 34 is of an L-shaped structure, and the long section of the L-shaped push rod 34 slides inside the guiding groove 333, and the short section contacts the outer side of the steel ring 2 as the long section slides, clamping and centering the steel ring 2.

[0056] Working process: When assembling the steel ring 2 and the cylinder body 5, first, place the steel ring 2 on the tooling platform 1. Then, start the first driving oil cylinder 32 on the tooling platform 1. The first driving oil cylinder 32 will drive the connecting block 321 to move in the sliding hole 11. While the connecting block 321 moves in the sliding hole 11, it will drive the pushing ring 31 to rotate a certain angle on the tooling platform 1. During the rotation of the pushing ring 31, it drives the push rod 34 to move radially inwards on the base 33. During the process of the push rod 34 moving radially inwards, the first roller bearings 331 on both sides of the push rod 34 will rotate along with the movement of the push rod 34. The inner side of the push rod 34 will come into contact with the outer side of the steel ring 2, so that each centering mechanism 3 on the tooling platform 1 centers and clamps the steel ring 2.

[0057] After centering is completed, the second driving oil cylinder 42 on the guiding mechanism 4 starts and pushes the guide rods 43 and the guiding wheels 44 on both sides to move radially inwards. The guiding wheels 44 will come into contact with the cylinder body 5 and control the gap between the steel ring 2 and the cylinder body 5. Then, the steel ring 2 is sleeved into the specified position on the outer side of the cylinder body 5, thus completing the guiding.

[0058] When the assembly of the steel ring 2 is completed, the centering mechanism 3 and the guiding mechanism 4 will return to their original positions driven by the first driving oil cylinder 32 and the second driving oil cylinder 42. Subsequently, repeat the above steps until the required number of steel rings 2 are successively sleeved into the specified positions on the outer side of the cylinder body 5.

[0059] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
