[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0023] See also Figure 1-Figure 4 A product-specific processing fixture includes a base 100, a rotating base 200 is assembled on the top of the base 100, a placement table 300 and a fixed plate 400 are fixedly connected to the top of the rotating base 200, and a fixing rod 500 is fixedly connected to the top of the placement table 300;

[0024] A clamping assembly 600 is provided between the fixed plate 400 and the fixed rod 500. The clamping assembly 600 includes an air pressure chamber 601, one end of which is fixedly connected to an elastic airbag 602. Placing a hollow sleeve-shaped product on the placement table 300 squeezes the elastic airbag 602, causing the elastic airbag 602 to be squeezed. The gas in the elastic airbag 602 is then squeezed into the air pressure chamber 601 to which it is fixed, increasing the pressure in the air pressure chamber 601. One end of the air pressure chamber 601 is slidably connected to a clamping rod 1 603, and the other end of the air pressure chamber 601 is slidably connected to a clamping rod 2 604. When the pressure in the air pressure chamber 601 increases, the clamping rod 1 603 and the clamping rod 2 604, which are slidably connected to the air pressure chamber 601, are driven to move. The side of the fixed plate 400 is connected to the arc-shaped splint 1 606 by setting a spring 1 605. There are two springs 1 605, and the two springs 1 605 are symmetrically distributed about the central axis of the arc-shaped splint 1 606. The side of the fixed rod 500 is connected to the arc-shaped splint 2 609 by setting a spring 2 607 and a telescopic rod 608. The bottom of the arc-shaped splint 1 606 and the top of the arc-shaped splint 2 609 are both provided with a slot, and the cross-sectional shape of the slot is adapted to the cross-sectional shape of the clamping rod 1 603 and the clamping rod 2 604. When the clamping rod 1 603 is moved out of the clamping slot on the arc-shaped splint 1 606, and the clamping rod 2 604 is moved out of the clamping slot on the arc-shaped splint 2 609, the arc-shaped splint 1 606 loses its restriction and then moves under the action of the spring 1 605, and the arc-shaped splint 2 609 loses its restriction and then moves under the action of the spring 2 607, so that the arc-shaped splint 1 606 and the arc-shaped splint 2 609 can quickly and stably clamp the hollow sleeve-shaped product, thereby improving the clamping effect of the device for such products and making the device easier to use.

[0025] When in use, the hollow sleeve-shaped product is placed on the placement table 300, and the elastic airbag 602 can be squeezed, so that the elastic airbag 602 is squeezed, and the gas in the elastic airbag 602 is immediately squeezed into the air pressure chamber 601 fixedly connected to it, so that the pressure in the air pressure chamber 601 increases, driving the clamping rod 1 603 and the clamping rod 2 604 slidingly connected to the air pressure chamber 601 to move, so that the clamping rod 1 603 moves out of the slot on the arc-shaped splint 1 606, and the clamping rod 2 604 moves out of the slot on the arc-shaped splint 2 609, and the arc-shaped splint 1 606 loses its restriction and then moves under the action of the spring 1 605, and the arc-shaped splint 2 609 loses its restriction and then moves under the action of the spring 2 607, so that the arc-shaped splint 1 606 and the arc-shaped splint 2 609 can quickly and stably clamp the hollow sleeve-shaped product. Example

[0026] See also Figure 1-Figure 4Based on the first embodiment, a reset assembly 700 is installed on the side of the second curved clamping plate 609. The reset assembly 700 includes a hydraulic chamber 701. The hydraulic chamber 701 extends through the placement platform 300 and the fixing rod 500 and is fixed to the placement platform 300 and the fixing rod 500. One end of the hydraulic chamber 701 is slidably connected to a pull rod 702. When the other end of the hollow sleeve-shaped product needs to be clamped, the pull rod 702 is pulled, and the hydraulic chamber 701, which is slidably connected to the pull rod 702, increases the pressure within the hydraulic chamber 701. The other end of the hydraulic chamber 701 is slidably connected to a transmission rod 703. The transmission rod 703 is located on the side of the second curved clamping plate 609 and is fixed to the second curved clamping plate 609. When the pressure in the hydraulic chamber 701 increases, the transmission rod 703 that is slidingly connected to the hydraulic chamber 701 moves, so that the transmission rod 703 drives the arc-shaped clamp plate 2 609 fixedly connected to it to reset. Then the hollow sleeve-shaped product can be taken out, and then the hollow sleeve-shaped product can be rotated and put back into the device, thereby further improving the usability of the device.

[0027] During use, based on Example 1, when it is necessary to clamp the other end of the hollow sleeve-shaped product, by pulling the pull rod 702, the hydraulic chamber 701 slidably connected to the pull rod 702 is cooperated to increase the pressure in the hydraulic chamber 701, driving the transmission rod 703 slidably connected to the hydraulic chamber 701 to move, so that the transmission rod 703 drives the arc-shaped clamping plate 2 609 fixedly connected to it to reset, and then the hollow sleeve-shaped product can be taken out, and then the hollow sleeve-shaped product can be rotated and put back into the device.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
