Description

Technical Field

[0001] The invention relates to the field of detection devices, in particular to a tire curing bladder detection device. Background Art

[0002] The vulcanization bladder is an inner mold installed inside the tire to support and shape the tire during the vulcanization molding process. It is cylindrical, and retaining rings are fixed at both ends of the axial direction, and a through hole is opened in the center of the retaining ring. When the vulcanization bladder is working, compressed air, nitrogen or hot water is input into it from the through holes at both ends to expand the vulcanization bladder and support the tire. The product quality of the vulcanization bladder will directly affect the production quality of the tire. Therefore, the vulcanization bladder needs to be tested by special testing equipment before it leaves the factory or is used.

[0003] Related technology can refer to the Chinese patent with announcement number CN211824330U, which discloses a device for detecting radial runout of a vulcanization capsule, including: a support assembly, a rotating mechanism, a measuring device and a clamping device. The support assembly includes: a base, a support column, a crossbeam, a first axial hole, a support seat, a boss and a second axial hole. The motor is installed at the end away from the base through the first axial hole. The rotating rod is connected to the motor through a coupling. The measuring device is installed under the crossbeam, and the clamping device is installed on the rotating rod. The device prevents the probability of the capsule being stuck in the gap when the airbag is not inflated in time by setting a clamping plate, thereby preventing the capsule from being clamped and broken. The air hole is set to input and output gas to the capsule, which facilitates the measurement of radial runout of the capsule.

[0004] Regarding the above-mentioned related technologies, when fixing the vulcanization bladder, it is necessary to put the clamping disc into the vulcanization bladder from the through hole at the end of the vulcanization bladder, and then tighten the bolts so that the bolts and the clamping disc fit on both sides of the vulcanization bladder retaining ring respectively, thereby clamping the vulcanization bladder. However, in order to make the clamping disc fit on the inner wall of the retaining ring, the maximum diameter of the clamping disc needs to be larger than the maximum diameter of the through hole. Therefore, when placing the vulcanization bladder on the clamping disc, it is necessary to stretch the vulcanization bladder, and after the clamping disc passes through the through hole and completely enters the vulcanization bladder, the vulcanization bladder needs to be reset, which is inconvenient when testing the vulcanization bladder.

[0033] Reference Figure 1 and Figure 2 A tire curing bladder detection device includes a support frame 1, an opening mechanism 2 and a detection head 3, and also includes two positioning disks 4. The two positioning disks 4 are parallel to each other and coaxial. Among the two positioning disks 4, one positioning disk 4 is set as a fixed disk 40, and the fixed disk 40 is rotatably connected to the support frame 1 along the circumferential direction. The support frame 1 is provided with a driving member, and the driving member includes a moving frame 11, a pushing cylinder 12 and a rotating motor 13. The moving frame 11 is slidably connected to the support frame 1 in a direction close to or away from the fixed disk 40. The positioning disk 4 corresponding to the fixed disk 40 is rotatably connected to the upper end of the moving frame 11. When the moving frame 11 moves, it drives the positioning disk 4 to approach or move away from the fixed disk 40.

[0034] Reference Figure 1 and Figure 2 The push cylinder 12 is fixedly connected to the support frame 1, and the output end of the push cylinder 12 is fixedly connected to the mobile frame 11. When the push cylinder 12 works, the mobile frame 11 is driven to move closer to or away from the fixed plate 40. The rotating motor 13 is installed at the lower end of the mobile frame 11, and a pulley group is provided between the positioning plate 4 and the rotating motor 13. When the rotating motor 13 works, the positioning plate 4 is driven to rotate through the pulley group.

[0035] Reference Figure 1 and Figure 2, the positioning disk 4 and the fixed disk 40 are both provided with a moving hole 41 along the axial direction, and a moving column 5 is provided in the moving hole 41. The moving column 5 passes through the moving hole 41 along the axial direction and fits with the inner wall of the moving hole 41. The positioning disk 4 and the fixed disk 40 are both installed with an electric push rod 1 42 on the side away from each other. When the electric push rod 1 42 is working, it drives the moving column 5 to move along the axial direction. A plurality of arc plates 51 are provided on the side where the two moving columns 5 are close to each other. In this embodiment, there are four arc plates 51 on the same moving column 5. The four arc plates 51 are grouped in pairs, and the two arc plates 51 in the same group are symmetrically arranged with the axis of the moving column 5 as the center. An annular groove 43 connected to the moving hole 41 is provided on the side where the two positioning disks 4 are close to each other. The moving column 5 is fixed with a sealing ring 52 adapted to the annular groove 43. The cooperation between the annular groove 43 and the sealing ring 52 is conducive to improving the air tightness between the moving column 5 and the positioning disk 4.

[0036] Reference Figure 3 and Figure 4 , two groups of arc plates 51 are staggered along the axis direction, wherein the arc plate 51 close to the moving column 5 is set as a passive plate 512, and the arc plate 51 far from the moving column 5 is set as an active plate 511. A sliding column 513 is fixedly arranged at one end of the passive plate 512 close to the moving column 5, and the moving column 5 is provided with a sliding groove 53 adapted to the sliding column 513 along the diameter direction, and the sliding column 513 is located in the sliding groove 53 and is slidably connected with the moving column 5 along the length direction of the sliding groove 53. The moving column 5 guides and limits the passive plate 512 through the sliding groove 53 to limit the rotation of the passive plate 512 and the movement along the axis direction.

[0037] Reference Figure 3 and Figure 4 A moving rod 514 is fixedly provided on one side of the active plate 511 close to the moving column 5. When the moving rod 514 moves, it drives the active plate 511 to approach. The moving column 5 is provided with a moving groove 54 adapted to the moving column 5 along the diameter direction. When the moving rod 514 is in the moving groove 54, it fits with the inner wall of the moving groove 54. The moving column 5 limits the moving rod 514 through the moving groove 54, so that the moving rod 514 moves along the length direction of the moving groove 54. In the initial state, the end of the moving rod 514 away from the active plate 511 fits with the moving column 5. At this time, the active plate 511 and the passive plate 512 are staggered.

[0038] Reference Figure 3 and Figure 4The movable column 5 is provided with an adjustment member, which includes a movable plate 61, a push rod 62 and a hinge rod 63. The movable plate 61 is located between all active plates 511 and passive plates 512. The movable column 5 is provided with a cavity, in which an electric push rod 2 64 is installed. The output end of the electric push rod 2 64 passes through the movable column 5 and is fixedly connected to the movable plate 61. When the electric push rod 2 64 is working, it drives the movable plate 61 to approach or move away from the movable column 5. The push rod 62 corresponds to the sliding column 513 one by one. The sliding column 513 is slidably connected with a sleeve 515 along the axial direction. The movable column 5 is provided with a limit groove 531 connected with the sliding groove 53 along the length direction of the sliding groove 53. When the sleeve 515 is located in the limit groove 531, it fits with the inner wall of the limit groove 531. One end of the push rod 62 is hinged to the sleeve 515, and the other end is hinged to the moving plate 61. When the moving plate 61 moves, the push rod 62 drives the sleeve 515 to move along the limiting groove 531, and when the sleeve 515 moves along the limiting groove 531, it drives the sliding rod to move.

[0039] Reference Figure 3 and Figure 4 The moving column 5 is also provided with a receiving groove 532 connected with the limiting groove 531, the receiving groove 532 is adapted to the sleeve 515, and the receiving groove 532 extends in the direction away from the passive plate 512 along the axis direction of the moving column 5. The hinge rod 63 corresponds to the moving rod 514 one by one, one end of the hinge rod 63 is hinged to the moving plate 61, and the other end is hinged to the moving rod 514. When the moving plate 61 moves under the action of the electric push rod 64, the hinge rod 63 drives the moving rod 514 to move.

[0040] Reference Figure 3 and Figure 4 The moving column 5 is provided with an avoidance groove 541 connected with the moving groove 54. The avoidance groove 541 is located at one end of the moving groove 54 away from the axis of the moving column 5, and extends in the direction away from the active plate 511 along the axis of the moving column 5. The avoidance groove 541 is adapted to the moving rod 514. When the moving rod 514 moves along the moving groove 54, it approaches or moves away from the avoidance groove 541. An abutment block 542 is provided in the avoidance groove 541. The abutment block 542 is slidably connected with the avoidance groove 541 along the length direction of the avoidance groove 541. A spring 543 is provided between the moving column 5 and the abutment block 542. One end of the spring 543 is fixedly connected to the abutment block 542, and the other end is fixedly connected to the moving column 5. The spring 543 has a tendency to push the abutment block 542 close to the active plate 511 in a natural state.

[0041] Reference Figure 3 and Figure 4 It should be noted that the distance between any two endpoints on the active plate 511 and the passive plate 512 is smaller than the curing bladder 10 (reference Figure 2 ) through hole 102 (reference Figure 2). In the initial state, the moving rod 514 is located at one end of the moving slot 54 close to the axis of the moving column 5, and the sliding column 513 is located at one end of the sliding slot 53 close to the axis of the moving column 5. At this time, the active plate 511 and the passive plate 512 are both close to the axis of the moving column 5. At this time, the distance between any two arc plates 51 is also smaller than the diameter of the through hole 102 of the vulcanizing bladder 10.

[0042] Reference Figure 3 and Figure 4 , the curing bladder 10 (reference Figure 2 ) is placed between the fixed disk 40 and the positioning disk 4, so that all the active plates 511 and passive plates 512 on the moving column 5 on the fixed disk 40 pass through the through hole 102 and enter the vulcanizing bladder 10. At this time, the corresponding electric push rod 64 is operated to drive the moving plate 61 close to the moving column 5. When the moving plate 61 moves, the push rod 62 and the hinge rod 63 move. When the push rod 62 moves, the sleeve 515 moves along the limiting groove 531 to the receiving groove 532. When the hinge rod 63 moves, the moving rod 514 moves to the avoidance groove 541. When the sleeve 515 is opposite to the receiving groove 532, the moving rod 514 moves to the position opposite to the avoidance groove 541. At this time, the projections of the active plate 511 and the passive plate 512 on the fixed disk 40 form a complete ring.

[0043] Reference Figure 3 and Figure 4 , the electric push rod 2 64 continues to drive the moving plate 61 to approach the moving column 5. At this time, the push rod 62 drives the sleeve 515 to enter the accommodating groove 532, so that the sleeve 515 slides relative to the sliding column 513 along the axial direction; the hinged rod 63 drives the moving column 5 to contact the abutment block 542, and presses the abutment block 542 into the avoidance groove 541. When the moving column 5 enters the avoidance groove 541, it drives the active plate 511 to approach the passive plate 512. When the moving column 5 moves to the maximum displacement in the avoidance groove 541, the active plate 511 and the passive plate 512 are coaxial and located in the same plane.

[0044] Reference Figure 2 and Figure 3 At this time, the active plate 511 and the passive plate 512 are connected end to end in sequence to form a complete ring, and the diameter of the ring is larger than the diameter of the through hole 102. The movable column 5 is driven to move by the electric push rod 42, so that the movable column 5 drives all the active plates 511 and the passive plates 512 to approach the fixed disk 40, and then clamps the retaining ring 101 of the vulcanization capsule 10. At this time, the movable column 5 cooperates with the fixed plate to block a through hole 102 of the vulcanization capsule 10.

[0045] Reference Figure 1 and Figure 2, the movable frame 11 is manipulated to approach the fixed plate 40, and the other retaining ring 101 of the vulcanization bladder 10 is clamped and blocked by another positioning plate 4 to complete the positioning of the vulcanization bladder 10. When the vulcanization bladder 10 is fixed, the positioning structure can pass through the through hole 102 without stretching the vulcanization bladder 10, which is conducive to improving the convenience of positioning the vulcanization bladder 10.

[0046] Reference Figure 1 and Figure 2 The opening mechanism 2 includes a medium placing box 21, a delivery pipe 22 and a connecting valve 23. The medium placing box 21 is used to place the medium for opening the vulcanizing bladder 10, such as compressed air, nitrogen or hot water. The moving column 5 located on the fixed column is provided with a medium pipe 44. One end of the medium pipe 44 extends to the end surface of the moving column 5 provided with an arc plate 51. The delivery pipe 22 is connected between the medium placing box 21 and the medium pipe 44, and the delivery pipe 22 and the medium pipe 44 are detachably connected. The connecting valve 23 is installed on the medium pipe 44 to control the connection and closing of the medium pipe 44. Initially, the medium pipe 44 is in a connected state. At this time, the medium control box sends the medium into the medium pipe 44 through the delivery pipe 22, and inputs the medium into the vulcanizing bladder 10 along the medium pipe 44, thereby supporting the vulcanizing bladder 10. After the vulcanizing bladder 10 is supported, the medium pipe 44 is closed through the connecting valve 23, and the delivery pipe 22 and the medium pipe 44 are separated.

[0047] Reference Figure 1 and Figure 2 The upper end of the support frame 1 is provided with a lifting frame 14, which reciprocates vertically. When the vulcanizing bladder 10 is positioned, the vulcanizing bladder 10 is directly below the lifting frame 14. The detection head 3 includes a vibration sensor 31, an audible and visual alarm 32, a detection plate 33 and a mounting frame 34. The mounting frame 34 is fixedly arranged at the lower end of the lifting frame 14. When the lifting frame 14 is working, the mounting frame 34 is driven to approach or move away from the vulcanizing bladder 10. The vibration sensor 31 is fixedly connected to the mounting frame 34. When the mounting frame 34 moves, it drives the vibration sensor 31 to move synchronously. The audible and visual alarm 32 is connected to the vibration sensor 31. When the vibration sensor 31 is triggered, an alarm is issued through the audible and visual alarm 32.

[0048] Reference Figure 1 and Figure 2The detection plate 33 includes a support plate 331 and a plurality of adjustment plates 332. The support plate 331 is located at the lower end of the mounting frame 34 and is slidably connected to the mounting frame 34 in a direction close to or away from the vibration sensor 31. There is a gap between the support plate 331 and the vibration sensor 31. When the support plate 331 contacts the vibration sensor 31, the vibration sensor 31 is triggered. All the adjustment plates 332 are located at the lower end of the support plate 331 and are slidably connected to the support plate 331 in a direction close to or away from the support plate 331. The support plate 331 is rotatably connected with a screw rod 333 corresponding to the adjustment plate 332. The screw rod 333 is inserted in the adjustment plate 332 and is threadedly connected to the adjustment plate 332. When the screw rod 333 is rotated, the screw rod 333 drives the adjustment plate 332 to approach or move away from the support plate 331.

[0049] Reference Figure 1 and Figure 2 The sides of all the adjustment plates 332 facing away from the support plate 331 form a detection port, which is adapted to the outer arc line of the vulcanization bladder 10 after it is stretched out. The adjustment plates 332 are driven close to the vulcanization bladder 10 by the lifting member, and the positioning plate 4 is driven to rotate by the rotating motor 13. When the positioning plate 4 rotates, the vulcanization bladder 10 is driven to rotate. When the outer edge of the vulcanization bladder 10 has a protrusion, the protrusion conflicts with the adjustment plate 332 during the rotation of the vulcanization bladder 10, and then the support plate 331 is pushed close to the vibration sensor 31 through the adjustment plate 332. After the vibration sensor 31 is triggered, the sound and light alarm 32 prompts the operator that the vulcanization bladder 10 has a defect.

[0050] The implementation principle of a tire curing bladder detection device according to an embodiment of the present application is as follows: when placing the curing bladder 10, all active plates 511 and passive plates 512 on the same movable column 5 are in a state of being close to each other, and it is convenient to pass the active plate 511 and the passive plate 512 through the through hole 102. After the active plate 511 and the passive plate 512 enter the curing bladder 10, the movable plate 61 is driven to approach the movable column 5 by the electric push rod 64. When the movable plate 61 moves, it drives the push rod 62 and the hinged rod 63 to move. The movement of the active plate 511 and the passive plate 512 is divided into two steps. When the sleeve 515 moves along the limiting groove 531, the passive plate 512 only moves along the diameter direction of the movable column 5. At this time, the hinged rod 63 drives the active plate 511 away from the axis of the movable column 5, so that the active plate 511 and the passive plate 512 are away from each other. When the passive plate 512 moves to the farthest distance from the axis of the moving column 5, the moving rod 514 is directly opposite to the avoidance groove 541, and the hinged rod 63 continues to drive the moving rod 514 into the avoidance groove 541, so that the active plate 511 approaches the passive plate 512 and moves to a state flush with the passive plate 512. At this time, the moving column 5 drives all active plates 511 and passive plates 512 to approach the corresponding positioning plate 4 or fixed plate 40, so that the active plate 511 and the passive plate 512 cooperate to press and position the retaining ring 101 along the circumference of the through hole 102, and the through hole 102 is closed while positioning the vulcanization bladder 10. When fixing the vulcanization bladder 10, there is no need to stretch the vulcanization bladder 10, which is conducive to improving the convenience of placing the vulcanization bladder 10, and then improving the convenience of testing the vulcanization bladder 10.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
