[0023] like Figure 1-4 As shown, this embodiment discloses a clamping device for assembling a cylinder assembly, including a turntable 1 and a turntable 2 for driving the turntable 1 to rotate, wherein the turntable 1 is a cam divider that rotates 90° in sequence, and the bottom valve cylinder clamping mechanism is four groups evenly distributed circumferentially, thereby forming four workstations. A plurality of bottom valve cylinder clamping mechanisms are circumferentially arranged on the turntable 1, and the bottom valve cylinder clamping mechanism includes a bottom valve clamping assembly 3 and a cylinder clamping assembly 4, the bottom valve clamping assembly 3 includes a bottom valve positioning sleeve 31 that can be inserted into the bottom valve, and the cylinder clamping assembly 4 includes an elastic clamp 41 for clamping the cylinder so that the cylinder and the bottom valve are axially aligned, and the elastic clamp 41 is arranged above the bottom valve positioning sleeve 31, and after the cylinder is squeezed into the elastic clamp 41 manually, the elastic clamp 41 can automatically clamp the cylinder by elastic force, thereby keeping the cylinder in a vertical position, but does not affect the movement of other mechanisms from top to bottom to press the cylinder into the bottom valve. Therefore, the utility model forms multiple workstations through multiple bottom valve cylinder clamping mechanisms, and the loading, pressing and unloading of the bottom valve and the cylinder can be completed at different workstations, thereby ensuring the safety of the workers. The rotation arrangement of multiple workstations on the turntable also facilitates the streamlined completion of loading, pressing and unloading, thereby improving the assembly efficiency.

[0024] In this embodiment, the cylinder clamping assembly 4 also includes a guide rod group 42, the guide rod group 42 includes two parallel guide rods 421, the bottom of the guide rod 421 of the guide rod group 42 is installed on the turntable 1, and the elastic clamp 41 is installed on the guide rod group 42 in a vertically adjustable manner. Specifically, the locking mechanism 422 is inserted into the guide rod 421 through a locking mechanism 422 that can be quickly loosened and tightened, so as to facilitate the flexible adjustment of the upper and lower clamping positions and adapt to the clamping of cylinders of different models.

[0025] In this embodiment, in order to improve the overall installation strength of the guide rod 421, the top of the guide rod 421 is connected to a guide rod fixing plate 5, so that the guide rod 421 is more difficult to shake.

[0026] In this embodiment, the elastic clamp 41 includes a first clamp 411, a second clamp 412, a clamp slider 413, a clamp guide rail 414, a mounting plate 415, a connecting rod 416, a spring 417, a centering slider 418 and a centering guide rail 419. The first clamp 411 and the second clamp 412 are arranged opposite to each other. The clamp slider 413 is installed at the bottom of the first clamp 411 and the second clamp 412. The clamp slider 413 is slidably connected with the clamp guide rail 414, so that the first clamp 411 and the second clamp 412 move in parallel. The clamp guide rail 414 and the centering guide rail 419 are installed on the mounting plate 415 (the locking mechanism 42 2 is installed on both sides of the mounting plate 415, the guide rod 421 passes through the locking mechanism 422 and the mounting plate 415, the connecting rod 416 is arranged on both sides of the centering slider 418, and one end of the connecting rod 416 is hinged to one side of the centering slider 418, and the other end is hinged to the first clamp 411 or the second clamp 412, the two ends of the spring 417 are respectively connected to the first clamp 411 and the second clamp 412, and avoid the clamping position of the first clamp 411 and the second clamp 412, the spring 417 maintains the closing trend of the first clamp 411 and the second clamp 412, and the centering guide rail 419 is vertically arranged in the middle of the clamp guide rail 414. When squeezed into the cylinder, the first clamp 411 and the second clamp 412 move away from each other, and the centering slider 418 moves toward the clamp guide rail 414. When the cylinder is taken out, the first clamp 411 and the second clamp 412 move relative to each other, and the centering slider 418 moves away from the clamp guide rail 414. The centering slider 418 and the centering guide rail 419 ensure that the center plane between the first clamp 411 and the second clamp 412 is fixed, ensuring that the cylinder and the bottom valve are axially aligned.

[0027] In this embodiment, the first clamp 411 and the second clamp 412 are relatively provided with V-shaped grooves 420, and the clamping input ends of the first clamp 411 and the second clamp 412 are relatively provided with rollers 410, so as to convert the sliding friction when the cylinder is squeezed into rolling friction, thereby avoiding damage to the outer wall of the cylinder.

[0028] In this embodiment, in order to adapt to the assembly of bottom valves with different outer diameters, the bottom valve clamping assembly 3 also includes a mounting base 32 and a positioning member 33. The mounting base 32 is mounted on the turntable 1 by screws, and the bottom valve positioning sleeve 31 is inserted into the mounting hole 321 of the mounting base 32. The positioning member 33 is mounted on the mounting base 32 and is detachably inserted into the positioning hole of the bottom valve positioning sleeve 31. Specifically, the positioning member 33 can be threadedly connected to the side wall of the mounting base 32, thereby connecting the mounting base 32 and the bottom valve positioning sleeve 31 as a whole. The bottom valve positioning sleeve 31 can be replaced at any time, and the assembly range is wider.

[0029] In this embodiment, in order to prevent the cylinder barrel and the bottom valve from being missed, a detection sensor 6 for detecting the cylinder barrel and the bottom valve is provided on one side of the bottom valve clamping assembly 3. If the detection sensor 6 fails to detect the bottom valve and the cylinder barrel before the pressing tool presses down the cylinder barrel and after the pressing action is completed, the detection sensor 6 will automatically alarm by feeding back a signal.
