The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

As shown in Figures 1 to 8, the air spring production bladder skin cutting equipment of the present invention includes: a frame 1, a support assembly 3, an adjustment assembly 4 and a cutting assembly 5. An annular conveyor belt is arranged on the frame 1 along the front-to-back direction, and a supporting structure is arranged on the conveyor belt. The conveyor belt is used to convey the bladder skin 11 to be cut. Two groups of support assemblies 3 for positioning the bladder skin 11 are symmetrically arranged on the frame 1 along the left-right direction. The support assembly 3 includes a plurality of support plates 31 arranged in a circular array. In this embodiment, six are described as an example. The ends of the left and right support plates 31 that are close to each other are provided with an inclined plate 32 for clamping the middle depression of the bladder skin 11. An inclined plate 32 is provided on one end of each support plate 31 that is close to each other, and the side of the inclined plates 32 that is close to each other is closer to the axis of the support assembly 3. In the left-right projection view, the two sides of the inclined plate 32 are respectively located on the two sides of the support plate 31. Two adjustment assemblies 4 are slidably arranged on the frame 1 along the left-right direction. The support assembly 3 and the adjustment assembly 4 are coaxially arranged. The adjustment assembly 4 is used to control the support plate 31 to move away from or closer to the outside along the axis of the support assembly 3. The cutting assembly 5 is installed on the frame 1. The cutting assembly 5 is coaxially arranged with the support assembly 3. The cutting assembly 5 can rotate around the axis of the support assembly 3 to cut the two end parts of the bladder skin 11.

As shown in Figures 4 to 7, the support plate 31 is arc-shaped, and six support plates 31 are arranged in a circumferential manner to form a support assembly 3. The two straight sides of the overlapping support plates 31 have extensions, and the extensions have the same curvature as the support plate 31. The two side edges extend along the inner arc surface and the outer arc surface of the support plate 31 respectively. The extensions on both sides of the support plate 31 are overlapped end to end to form the support assembly 3, and the sum of the thicknesses of the extensions on both sides is the same as that of the support plate 31. The end of the support plate 31 that is close to each other is hingedly provided with an inclined plate 32, and a fastening bolt for fastening the inclined plate 32 and the support plate 31 is provided at the hinge. By adjusting the inclination angle of the inclined plate 32, it can adapt to the recessed parts of the bladder skin 11 of different sizes for clamping and positioning. The support plate 31 is elastic, and is preferably a metal plate that can deform to adapt to the inner wall of the bladder skin 11. The outer arc surface of the support plate 31 is smooth to reduce the friction between the support plate 31 and the bladder skin 11. Ball bearings or lubricants can be provided on the outer arc surface of the support plate 31.

As shown in Figures 3 to 5, the above-mentioned adjustment component 4 includes: an adjustment rod 41, an umbrella component 42, a trigger component 43 and a driving source 44. The two adjustment rods 41 are slidably arranged on the frame 1 along the left and right directions. Under the action of the driving source 44, the adjustment rod 41 slides along the left and right directions. The driving source 44 is preferably an electric telescopic rod or a hydraulic telescopic rod. A sliding groove 411 is arranged on the circumferential side wall of the end where the two adjustment rods 41 are close to each other. The sliding groove 411 is uniformly distributed along the circumferential direction of the axis of the adjustment rod 41. A guide rod 311 perpendicular to the axis of the support component 3 is arranged on the inner arc surface of the support plate 31. The guide rod 311 slides with the sliding groove 411, and the support plate 31 can move close to or away from the axis of the adjustment rod 41. The umbrella component 42 is arranged at one end where the two adjustment rods 41 are close to each other, and drives the support component 3 to open when the trigger component 43 abuts against each other.

As shown in Figures 3 to 6, the umbrella-shaped component 42 includes a sliding rod 421 and a hinged rod 422. The sliding rod 421 is coaxially arranged with the adjusting rod 41. The sliding rod 421 slides along the axial direction of the adjusting rod 41. The two ends of the hinged rod 422 are respectively hinged to the support plate 31 and the sliding rod 421. When the sliding rod 421 slides along the axial direction of the adjusting rod 41, the hinged rod 422 drives the support plate 31 hinged at the other end to move along the sliding groove 411 to approach or move away from the axis of the adjusting rod 41, so that the support component 3 can expand or shrink to adapt to the capsule skin 11 of different diameters.

As shown in Figures 4 to 8, the trigger component 43 includes a push rod 431 and a spring 432. The push rod 431 is coaxially slidably arranged with the sliding rod 421. The spring 432 is located between the push rod 431 and the sliding rod 421. One end of the spring 432 is fixedly connected to the push rod 431, and the other end is fixedly connected to the sliding rod 421. In the initial state, the distance between the push rod 431 and the sliding rod 421 is the maximum. The spring 432 has an elastic force. When the two adjusting rods 41 approach each other, the two trigger components 43 resist each other, and the sliding rod 421 slides and contracts toward the inside of the adjusting rod 41 along the axis of the adjusting rod 41. The sliding rod 421 causes the support plate 31 to move away synchronously in the radial direction of the axis of the support assembly 3 through the hinge rod 422.

As shown in Figures 3 to 6, the cutting assembly 5 is coaxially rotatably arranged on the adjusting rod 41, and the cutting assembly 5 includes: a rotating ring 51, a driving source 52 and a cutting unit. The rotating ring 51 is rotatably sleeved on the adjusting rod 41, and the rotating ring 51 slides axially along the adjusting rod 41. The driving source 52 is located between the adjusting rod 41 and the rotating ring 51. The driving source 52 is preferably an electric telescopic rod or a hydraulic telescopic rod. The driving source 52 enables the rotating ring 51 to slide axially along the adjusting rod 41 to adjust the distance between the cutting unit and the bladder skin 11. The rotating ring 51 is provided with a cutting unit for cutting the bladder skin 11.

As shown in Figures 6 to 8, the cutting unit includes a cutting knife 53, an electric telescopic rod 1 54 and an electric telescopic rod 2 55. The electric telescopic rod 1 54 is arranged in a direction perpendicular to the rotation axis of the rotating ring 51 itself. The electric telescopic rod 2 55 is horizontally arranged on the side of the top of the electric telescopic rod 14 close to the bladder skin 11 along the left and right direction. The top of the electric telescopic rod 2 55 is provided with a rotatable cutting knife 53. The electric telescopic rod 1 54 is telescopic in a direction perpendicular to the rotation axis of the rotating ring 51 itself to drive the cutting knife 53 to adapt to bladder skins 11 of different diameters. The electric telescopic rod 2 55 is horizontally telescopic in the left and right direction to drive the cutting knife 53 to adjust the width of the bladder skin 11 removed.

The implementation principle of the embodiment of the present invention is as follows: the bladder skin 11 to be processed is transported to the axial position of the support assembly 3 by a conveyor belt, and the driving source 44 drives the two adjusting rods 41 to approach each other. When the two top rods 431 are in contact, the top rod 431 drives the sliding rod 421 to slide and shrink into the adjusting rod 41, so that the support plate 31 hinged at the other end of the hinged rod 422 moves along the sliding groove 411 in a direction away from the axis of the adjusting rod 41, so that the support assembly 3 is opened. When the outer arc surface of the support plate 31 is against the inner wall of the bladder skin 11, the support plate 31 is deformed to adapt to the shape of the inner wall of the bladder skin 11. When the support plate 31 cannot expand outwards due to the restriction of the bladder skin 11, the driving source 44 further drives the two adjusting rods 431 to slide and shrink into the adjusting rod 41. 41 approaches, at this time, the push rod 431 overcomes the elastic force of the spring 432, so that the distance between the push rod 431 and the sliding rod 421 is reduced, and the inclined plates 32 arranged on the support plate 31 approach each other to press against the concave part of the bag skin 11 to position it, and then control the driving source 2 52 to drive the rotating ring 51 to move to a position close to the bag skin 11, and further adjust the cutting knife 53 to a predetermined position through the electric telescopic rod 1 54 and the electric telescopic rod 2 55, start the cutting knife 53 and the rotating ring 51 to cut the bag skin 11, and after the cutting is completed, the driving source 1 44 drives the adjusting rod 41 to reset, until the device resets to the initial state, and the conveyor belt transports the next bag skin 11 to be cut to the cutting position.
