Description

Technical Field

[0001] This utility model relates to the field of flexible clamping mechanisms, and more specifically, to a flexible clamping mechanism for grinding the outer diameter of a valve stem. Background Technology

[0002] Flexible gripping is a grasping technology that mimics the soft structures of human hands or biological tentacles. It does not rely on precise geometric models and complex control algorithms, but rather utilizes the inherent flexibility, adaptability, and passive deformation of materials to wrap around and conform to the surface of objects, thereby achieving stable and non-destructive gripping.

[0003] When performing external cylindrical grinding, existing valve stems require the use of flexible clamping fixtures for clamping. The clamping points are relatively small, which can easily cause one end of the valve stem to be unable to remain horizontal when dealing with longer valve stems, affecting the machining effect and also creating safety hazards, making the machining operation difficult.

Pushing the clamping spring will move the movable clamping frame to clamp the stem. During grinding, this avoids the safety hazard caused by excessive tool approach and the stem flying out during processing.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Example:

[0024] Please see Figure 1-3 A flexible clamping mechanism for grinding the outer diameter of a valve stem includes: a three-jaw chuck body 1, with multiple flexible jaws 2 installed at the output end of the three-jaw chuck body 1, and multiple insertion holes opened on one side outer wall of the three-jaw chuck body 1; and an auxiliary clamping assembly, which includes: multiple mounting rods 4, an extension plate 5, and two clamping components. The multiple mounting rods 4 are detachably connected to the corresponding insertion holes, the extension plate 5 is detachably connected between one end of the multiple mounting rods 4, and the two clamping components are both disposed between the inner walls of the extension plate 5.

[0025] In a specific embodiment of this utility model, a flexible gripper 2 is provided on the three-jaw chuck body 1, and the flexible gripper 2 is positioned by the gripper positioner 3. When facing a long rod, the assisting clamping component is fixed on the three-jaw chuck body 1, and the positioning is completed through the insertion hole and the mounting rod 4. Then, the clamping spring 7 is pushed to push the movable clamping frame to move towards each other, and additional clamping is performed on the suspended rod. During grinding, this can avoid the safety hazard caused by the tool getting too close during the processing and the rod flying out directly. When facing different rods, the mounting rod 4 can be replaced to adapt to them, which is conducive to processing operations.

[0026] Specifically, both clamping components include: an inner extension fixing frame 6, multiple push clamping springs 7, a movable clamping frame 8, and a contact clamping block 10. The inner extension fixing frame 6 is fixedly connected to the inner wall of the extension plate 5. The multiple push clamping springs 7 are installed on one side of the outer wall of the inner extension fixing frame 6. The movable clamping frame 8 is fixedly connected to one end of the multiple push clamping springs 7. The contact clamping block 10 is detachably connected to one side of the outer wall of the contact clamping block 10.

[0027] In this embodiment, a push clamping spring 7 is provided through the inner extension fixing frame 6. The push clamping spring 7 pushes the movable clamping frame 8 to move towards each other. It is necessary to ensure that the pushing force of the push clamping spring 7 on both sides is consistent. The contact clamping block 10 is a block with a certain elasticity to avoid direct damage to the rod.

[0028] Specifically, both clamping components include two guide rods 9 and two limiting discs 11. The two guide rods 9 are fixedly connected to one side of the outer wall of the inner extension fixing frame 6, and the two limiting discs 11 are respectively fixedly connected to one end of the corresponding guide rod 9.

[0029] In this embodiment, the guide rod 9 restricts the movement path of the movable clamping frame 8, and the limiting disk 11 restricts the maximum movement path while preventing it from falling off.

[0030] Specifically, each of the two movable clamping frames 8 has two through holes on one side of its outer wall, and the four through holes are slidably engaged with the corresponding guide rods 9.

[0031] In this embodiment, the guide rod 9 is accommodated through a through hole, allowing it to move.

[0032] Specifically, multiple hollow grooves 12 are provided on one side of the outer wall of the extension plate 5.

[0033] In this embodiment, the weight of the extension disc 5 is reduced by using the hollowed-out groove 12, thereby reducing its cost.

[0034] Specifically, gripper positioners 3 are installed on one outer wall of each of the multiple flexible grippers 2.

[0035] In this embodiment, the flexible clamping effect is achieved by the cooperation of the gripper locator 3 and the flexible gripper 2.

[0036] Working principle: Flexible jaws 2 are set on the three-jaw chuck body 1 and positioned by the jaw positioner 3. When facing a long rod, the assisting clamping component is fixed on the three-jaw chuck body 1 and positioned through the insertion hole and mounting rod 4. Then, the clamping spring 7 is pushed to move the movable clamping frame towards each other, providing additional clamping for the suspended rod. During grinding, this avoids the safety hazard caused by the tool getting too close and the rod flying out directly. When facing different rods, the mounting rod 4 can be replaced to adapt to different rods, facilitating the machining operation.

[0037] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
