[0017] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings: Example: Figures 2-7 As shown, a quick clamping fixture for dry ice shaft cylinders includes a base 3. Two sets of parallel rotary positioning mechanisms 5 are fixedly installed on one side of the base, and a stepped surface is provided on the other side of the base. V-shaped slots 4 are opened on the stepped surface corresponding to the rotary positioning mechanisms. A cylinder fixing plate 7 is fixedly connected to the side end of the stepped surface of the base via a connecting plate 6. Two sets of cylinders 8 are installed on the cylinder fixing plate. The cylinders are set with the V-shaped slots and rotary positioning mechanisms. The rotary positioning mechanism includes a fixing block 9. A rotating rod 16 is rotatably connected to the fixing block. A flat, oval top block 15 is fixedly connected to the rotating rod. A rotary positioning block 10 is rotatably connected to the front end of the fixing block. A cross slot 23 is opened on the inner side of the rotary positioning block. The cross slot cooperates with the top block. The rotary positioning block is opened and locked by rotating the top block. Positioning insertion holes 20 are opened on the front end of the rotary positioning block corresponding to the four claws of the dry ice shaft.

[0018] The fixed block has sliding grooves on both sides, and positioning blocks 12 are slidably connected in the sliding grooves. The inner end of the positioning block is pressed against the top block, and the outer end of the positioning block is connected to a spring 13. The outer side of the spring is connected to a spring pressure plate 14, which is fixedly installed on the fixed block by bolts.

[0019] A pressure plate 11 is provided on the outer side of the rotating positioning block, and the pressure plate is fixed to the fixing block by bolts. The top of the rotating rod protrudes from the fixing block and has a rotating opening 21. The rotating opening is an internal hexagonal slot.

[0020] The fixed block has a switch scale 22 corresponding to the rotating port. A coupling is fixedly connected to the cylinder output end. The fixed block is fixedly connected to the base by a locating pin 17 and bolts.

[0021] The cylinder mounting plate is fixedly connected to the base by cylinder connecting plate fixing bolts 18 passing through the connecting plate. The cylinder is connected to the cylinder mounting plate by cylinder fixing bolts 19.

[0022] In use, the workpiece is placed in the V-shaped groove, with the four jaws of the workpiece corresponding to the positioning holes at the front end of the rotating positioning block. The output end of the cylinder is connected to the other end of the workpiece via a coupling. The cylinder is started to press the workpiece onto the rotating positioning block for positioning. Then, the rotating rod is rotated to lock the top block into the cross groove of the rotating positioning block. The workpiece's cylindrical surface is then partially machined. After machining, the rotating rod is rotated to disengage the top block from the cross groove, releasing the lock. The workpiece is then rotated 90 degrees, and the rotating rod is rotated again to lock the top block into the cross groove of the rotating positioning block. The machining of the workpiece's cylindrical surface continues, and this process is repeated until the machining of the entire cylindrical surface of the workpiece is completed.
