[0030] The present invention provides a disassembly device for a U-shaped card. Figure 1 and Figure 2 As shown, the disassembly device includes a workbench 1, on which a disassembly component, a fixing component and a controller 30 are arranged, wherein a valve body 10 is arranged on the fixing component, and the valve body 10 has a U-shaped card 20. Here, when the valve body 10 is set on the workbench 1 and fixed by the fixing component, the disassembly component of this embodiment is used to disassemble the U-shaped card 20 on the valve body 10.

[0031] The controller 30 is provided on the workbench 1 and may be, for example, a PLC controller, and is used to control the fixing assembly and the disassembly assembly to achieve the disassembly of the U-shaped clip 20. In this embodiment, the disassembly device is used to remove the U-shaped clip 20 from the valve body 10 during maintenance of the valve body 10 to replace the U-shaped clip 20 with a different specification.

[0032] Specifically, the disassembly assembly includes a guide shaft 2, the middle part of the guide shaft 2 is set on the workbench 1 through a bracket 21, and the guide shaft 2 here is set on the workbench 1 along a first direction, and the first direction here can be, for example, the length direction of the workbench 1.

[0033] Furthermore, a driving device 3 is provided at the first end of the guide shaft 2. The driving device here can be, for example, a hydraulic cylinder. The driving device 3 is used to drive the rotation of the guide shaft 2. The second end of the guide shaft 2 is connected to the first end of the hydraulic rod 4. The guide shaft 2 here can drive the hydraulic rod 4 to rotate. The second end of the hydraulic rod 4 is arranged relative to the U-shaped card 20 to facilitate the disassembly of the U-shaped card 20. The hydraulic rod 4 can be extended and retracted in the direction of the fixed component. The hydraulic rod 4 here can adjust its extension and retraction degree based on the different specifications of the U-shaped cards 20, thereby realizing the disassembly of different U-shaped cards 20 through its second end.

[0034] Preferably, the second end of the guide shaft 2 is supported by an end bracket 22 , so as to support the hydraulic rod 4 .

[0035] Furthermore, a through hole 41 is provided at the second end of the hydraulic rod 4, and a fixing pin 42 is provided in the through hole 41. The fixing pin 42 can cooperate with the through hole 41 to be inserted into the U-shaped clips 20 of different specifications. The outer diameter of the through hole 41 can be set as needed to facilitate the use of fixing pins 42 of different specifications to complete the removal of the U-shaped clips 20 of different specifications.

[0036] Furthermore, the fixing assembly includes a guide rail 5, which is arranged on the workbench 1 along a second direction, where the second direction is perpendicular to the first direction, and can be, for example, the width direction of the workbench 1. The guide rail 5 can be, for example, two parallel slide rails, with a slide plate 6 provided on the guide rail 5, and the slide plate 6 slides on the guide rail 5 along the second direction.

[0037] Specifically, in order to control the sliding of the slider 6 on the guide rail 5, a guide groove and a screw rod 7 are set on the lower surface of the slider 6, and the guide groove and the screw rod 7 cooperate with each other, for example, by rotating the screw rod 7 to control the movement of the slider 6 on the guide rail 5. The screw rod 7 here is set along the second direction.

[0038] Furthermore, a clamping device 8 is provided on the slide 6 for clamping the valve body 10. The clamping device 8 may be, for example, a pneumatic vise or a hydraulic clamp. When securing the valve body 10 using the clamping device 8, it is necessary to ensure that the U-shaped clamp 20 on the valve body 10 is positioned toward the disassembly assembly, particularly toward the second end of the hydraulic rod 4. Preferably, the clamping device 8 is a hydraulic clamp, which facilitates movement on the workbench 1, enabling the disassembly of multiple U-shaped clamps 20 during a single assembly, thus providing greater flexibility.

[0039] In addition, a protective cover may be provided on the workbench 1 to control the closure of the protective cover when the U-shaped clip 20 on the valve body 1 is removed. In addition, a sensor may be provided on the workbench 1 to sense whether the protective cover is closed.

[0040] In some embodiments, a collection box may be further provided on the workbench 1 to collect the disassembled U-shaped card 20 .

[0041] It should be noted that the contact surface between the clamping device 8 , such as a hydraulic clamp, and the valve body 10 is made of rubber or other materials to avoid secondary scratches on the surface of the valve body 10 during maintenance.

[0042] In addition, feet 11 may be provided at the bottom of the workbench 1 to fix the workbench 1 on the ground. Of course, universal wheels with locking devices may also be provided to facilitate adjustment of the position of the workbench 1 .

[0043] When using the disassembly device involved in this embodiment, the valve body 10 to be disassembled is first placed on the positioning tooling position of the hydraulic clamping pliers jaws serving as the clamping device 8, and the controller 30 is operated to clamp the valve body 10 through the hydraulic clamping pliers. The contact surface between the hydraulic clamping pliers and the valve body 10 here can be made of rubber or other materials to avoid secondary scratches on the surface of the valve body 10 during maintenance.

[0044] According to the actual position of the U-shaped card 20 of the valve body 10 of different specifications and models, the extension distance of the hydraulic rod 4 is controlled by the controller 30. The extension distance here can be adjusted by the controller 30.

[0045] By manually cranking the lead screw 7, the hydraulic clamp is adjusted to a suitable position along the guide rail 4, that is, the first U-shaped clip to be disassembled is adjusted so that it is located below the through hole 41 at the second end of the hydraulic rod 4; according to the specifications of the first U-shaped clip, the matching fixing pin 42 is inserted from the through hole 41 at the second end of the hydraulic rod 4 to the center position of the first U-shaped clip.

[0046] Furthermore, when, for example, the sensor senses that the protective cover is fully closed, the red warning light on the controller 30 goes out, and the device start button becomes usable. After the device is started, the hydraulic rod 4 is controlled to move slowly (a fixed speed can be set by the controller 30 or the movement speed can be manually controlled), thereby driving the first U-shaped clip to remove the valve body 10. When the sensor senses that the first U-shaped clip is fully removed, the hydraulic rod 4 is controlled to stop moving, causing the first U-shaped clip to fall into the collection box.

[0047] After the first U-shaped clip is removed, the hydraulic rod 4 is controlled to return to its origin. The driving device 3 controls the hydraulic clamp to move left and right, automatically moving the second U-shaped clip to the center of the second end of the hydraulic rod 4 (forming a straight line to wait for external pulling). The parameters of the moving position here can be adjusted by the controller 30. The protective cover is opened, the fixing pin 42 is inserted, and the protective cover is closed. The disassembly assembly is activated to pull out the second U-shaped clip. The equipment can only be started after the protective cover is closed in place to improve the overall safety of the equipment. The above operation is repeated until all U-shaped clips are pulled out.

[0048] The utility model completes the automatic disassembly of the entire group of U-shaped clips through control, and can complete the disassembly of U-shaped clips of different specifications by matching with different fixing pins. At the same time, it is convenient to complete the disassembly of multiple U-shaped clips in one assembly, which has high flexibility and improves the degree of automation of the equipment. It can also avoid secondary scratches on the surface of the valve body during maintenance.
