[0040] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0041] like Figures 1-4 As shown, this embodiment provides an air core release device for an inner tube valve, comprising: an air core clamping device 100; an air cap clamping device 200 for clamping the air cap 720 of the valve 700, the air cap clamping device 200 being arranged around the air core clamping device 100; a rotating device 230 for driving the air cap clamping device 200 to rotate; and a stroke mechanism 300 for driving the air cap clamping device 200 to move, or simultaneously driving the air cap clamping device 200 and the air core clamping device 100 to move together. It can be understood that the stroke mechanism 300 can be a mechanical structure capable of active displacement, such as an electric slide, a hydraulic cylinder, or a traveling trolley. In this embodiment, the stroke mechanism 300 simultaneously drives the air cap clamping device 200 and the air core clamping device 100 to move together. The air cap clamping device 200 and the air core clamping device 100 are located on the movable part of the stroke mechanism 300; for example, if the stroke mechanism 300 is an electric slide, it is located on its sliding plate. In this embodiment, during operation, the operator first fixes the inner tube in a predetermined position. The stroke mechanism 300 drives the air cap clamping device 200 and the air core clamping device 100 to move to the predetermined position of the inner tube nozzle 700. The air cap clamping device 200 and the air core clamping device 100 then clamp the air cap 720 and the air core 710 of the nozzle 700, respectively. Then, the rotating device 230 starts to rotate the air cap clamping device 200, rotating the air cap 720. At this time, the stroke mechanism 300 moves in the opposite direction, causing the air cap 720 to gradually unscrew and detach from the nozzle 700 along with the air core 710. Finally, the air core 710 leaves the nozzle 700 to facilitate the subsequent air intake and deflation of the inner tube. Similarly, after the inner tube is deflated, the stroke mechanism 300 and the rotating device 230 reverse their operation to put the air core 710 and the air cap 720 back onto the nozzle 700.
[0042] In some embodiments, the air core clamping device 100 and the air cap clamping device 200 perform clamping actions under the drive of the same driving device 400. In this embodiment, as shown... Figures 3-5As shown, the air core clamping device 100 comprises air core clamping jaws 110 and a first driving assembly for pushing the air core clamping jaws 110 to clamp, the air cap clamping device 200 comprises air cap clamping jaws 210 and a second driving assembly for pushing the air cap clamping jaws 210 to clamp, and the movable part of the stroke mechanism 300 is provided with a driving device 400 for simultaneously driving the first driving assembly and the second driving assembly. It can be understood that the air core clamping jaws 110 are a mechanical clamping jaw structure in the prior art, which comprises a main body 111, a pair of clamping blocks 112 hinged to the main body 111, and the first driving assembly is directly or indirectly connected to the pair of clamping blocks 112 through a connecting rod assembly, and the pair of clamping blocks 112 are clamped by being pushed and pulled by the first driving assembly. Similarly, the second driving assembly pushes and pulls the air cap clamping jaws 210 to clamp. The first driving assembly and the second driving assembly can be push rods or others. The above clamping jaw structures all belong to the category that can be understood by those skilled in the art. In the embodiment, the driving device 400 is used as the power source of the first driving assembly and the second driving assembly, and under the driving of the driving device 400, the first driving assembly and the second driving assembly move and push and pull the air core clamping jaws 110 and the air cap clamping jaws 210 to clamp or open. The driving device 400 can be an electric sliding table, an oil cylinder, a walking trolley or other mechanical structures that can actively displace.
[0043] In some embodiments, as shown in Figures 3-4 The first driving assembly and / or the second driving assembly is provided with a tension spring 240 for stabilizing the clamping of the clamping jaw, one end of the tension spring 240 is connected to the first driving assembly or the second driving assembly, and the other end of the tension spring 240 is connected to the driving device 400. It can be understood that the tension spring 240 can provide a stable clamping force, an automatic reset function and better adaptability for the air cap clamping jaws 210 or the air core clamping jaws 110.
[0044] In some embodiments, as shown in Figures 3-4 The air cap clamping jaws 210 comprise a support 211 and a pair of clamping jaws 212, the pair of clamping jaws 212 are hinged in the support 211, and the support 211 is in transmission connection and synchronous rotation with the output wheel 510 of the motor 500. In the embodiment, the support 211 is a wheel disc structure, the pair of clamping jaws 212 are vertically inserted into the support 211, the middle part of the pair of clamping jaws 212 is hinged to the support 211, and the outer periphery of the support 211 is in transmission connection with the output wheel 510 of the motor 500 through a belt. The motor 500 output wheel 510 and the electronic device are arranged in the movable part of the stroke mechanism 300.
[0045] In some embodiments, as shown in Figures 3-4As shown, the gas cap clamp jaw 210 is provided with a first symmetry line, the gas cap clamp jaw 210 is symmetrically constructed with the first symmetry line, the gas core clamp jaw 110 is provided with a second symmetry line, and the first symmetry line and the second symmetry line are coincidentally arranged. It can be understood that the symmetric arrangement of the gas cap clamp jaw 210 and the gas core clamp jaw 110 can guarantee the synchronism and accuracy of clamping, so that the gas cap 720 and the gas core 710 can maintain a good vertical posture, which is convenient for dismounting and mounting.
[0046] In some embodiments, as shown in Figures 3-5 As shown, the first driving assembly includes a main fixed tube 121 fixed to the movable part of the stroke mechanism 300, the gas core clamp jaw 110 is arranged at the upper end of the main fixed tube 121, the first tensioning rod 122 is arranged between the pair of clamping blocks 112 of the gas core clamp jaw 110, the first tensioning rod 122 is slidably arranged in the main fixed tube 121 and is in transmission connection with the driving device 400; the support 211 is sleeved on the main fixed tube 121, and the second driving assembly is slidably arranged on the outer periphery of the main fixed tube 121. It can be understood that when the driving device 400 pulls the first tensioning rod 122 downward, the upper end of the first tensioning rod 122 pushes the lower part of the pair of clamping blocks 112 of the gas core clamp jaw 110 to turn outward, and since the middle part of the pair of clamping blocks 112 is in a hinged state, the upper part of the pair of clamping blocks 112 will be clamped inward at this time.
[0047] In some embodiments, as shown in Figures 3-5 As shown, the second driving assembly includes a tensioning sleeve 221 slidably arranged on the main fixed tube 121 and an inner rotating part 222 sleeved on the tensioning sleeve 221, the upper part of the tensioning sleeve 221 is arranged between the gas cap clamp jaw 210, the second tensioning rod 223 is arranged on both sides of the inner rotating part 222, and the second tensioning rod 223 is in transmission connection with the driving device 400. It can be understood that when the driving device 400 pulls the second tensioning rod 223 downward, the second tensioning rod 223 pulls the inner rotating part 222 and the tensioning sleeve 221 downward, and the tensioning sleeve 221 pushes the lower part of the pair of clamping jaws 212 of the gas cap clamp jaw 210 to turn outward, and since the middle part of the pair of clamping jaws 212 is in a hinged state, the upper part of the pair of clamping jaws 212 will be clamped inward at this time. In the present embodiment, the first tensioning rod 122 and the second tensioning rod 223 are both arranged through the main rod fixing part 360 arranged on the movable part of the stroke mechanism 300. The both ends of the first tensioning rod 122 and the second tensioning rod 223 are both provided with anti-loosening nuts 123.
[0048] In some embodiments, as shown in Figure 4 As shown, the driving device 400 includes a sliding table cylinder plate 410 and a cylinder 420 connected with the sliding table cylinder plate 410, the first tensioning rod 122 and the second tensioning rod 223 are arranged through the sliding table cylinder plate 410, and the tensioning spring 240 is arranged between the end of the first tensioning rod 122 and the sliding table cylinder plate 410 and between the end of the second tensioning rod 223 and the sliding table cylinder plate 410.
[0049] In some embodiments, asFigure 3 As shown, a bearing assembly 250 is provided between the support member 211 and the main fixed tube 121 and / or between the inner rotating member 222 and the tensioning sleeve 221. It can be understood that the bearing assembly 250 is composed of one or more conventional bearings such as deep groove ball bearings and angular contact ball bearings.
[0050] In some embodiments, such as Figures 5-6 As shown, the stroke mechanism 300 includes a tooling plate 310, a main fixing plate 330, a first thrust cylinder 340, and a second thrust cylinder 340. The main fixing plate 330 is an L-shaped plate, which includes a vertical plate and a horizontal plate. The vertical plate of the main fixing plate is slidably mounted on the slide rail 320 on the front side of the tooling plate 310. The first thrust cylinder 340 is fixed on the back side of the tooling plate 310. The cylinder rod end of the first thrust cylinder 340 is connected to the second thrust cylinder 370. The second thrust cylinder 370 is connected to an elastic clamping assembly 350. The elastic clamping assembly 350 is connected to the horizontal plate of the main fixing plate 330. The upper part of the slide rail 320 of the tooling plate 310 is provided with a limiting stop 321 for positioning the main fixing plate 330. In this embodiment, the tooling plate 310 serves as the fixed part of the stroke mechanism 300, and the main fixed plate 330 serves as the movable part of the stroke mechanism 300. That is, the main fixed plate 330 slides up and down along the slide rail 320 under the push and pull of the first thrust cylinder 340. At the same time, in order to achieve more accurate positioning and ensure that the air cap gripper 210 and the air core gripper 110 can accurately reach the predetermined two sides of the air nozzle 700, this embodiment also provides an elastic clamping component 350 and a corresponding limit stop 321 on the slide rail 320. Specifically, the elastic clamping assembly 350 includes a lower top plate 351 and an upper top plate 352. Multiple guide rods 353 pass through the lower top plate 351 and the upper top plate 352, and clamping springs 354 are mounted on the guide rods 353. The upper top plate 352 is connected to the main fixed plate 330, and the lower top plate 351 is connected to the cylinder rod end of the second thrust cylinder 370. When the main fixed plate 330 is pushed by the first thrust cylinder 340 to the limit stop 321 of the slide rail 320, the second thrust cylinder 370 continues to push the lower top plate 351, causing the lower top plate 351 to press against the clamping springs 354, thus clamping the upper top plate 352 and the main fixed plate 330 together. This effectively prevents operational errors caused by repeated operations, which could lead to the first thrust cylinder 340 failing to lift the main fixed plate 330 to its proper position, resulting in the air cap gripper 210 and the air core gripper 110 becoming misaligned.
[0051] In some embodiments, such as Figures 1-5 As shown, a positioning device 600 is included for clamping and positioning the inner tube valve 700 body. It is understood that the positioning device 600 ensures that the inner tube valve 700 remains fixed in a fixed state during operation, preventing it from shifting or deviating, thus effectively improving the operational stability of the equipment. In this embodiment, the positioning device 600 includes a valve clamping device 610 fixed relative to the tooling plate 310.
