[0051] The swing frame 2 is rotatably connected to the base 1 and can swing longitudinally relative to the base 1.

[0052] The rotating table 3 is arranged on the swing frame 2, the rotating table 3 is provided with a cavity 31 for placing the butterfly valve body 100, and the cavity 31 is movably provided with a clamping jaw 6 at two sides.

[0053] The position detector 4 is connected to the base 1 or the swing frame 2 and is used for detecting the position of the mounting surface 110.

[0054] The control assembly 5 is connected to the position detector 4, the clamping jaw 6, the rotating table 3 and the swing frame 2.

[0055] The control assembly 5 can control the opening of the clamping jaw 6, the rotation of the rotating table 3 and the swinging of the swing frame 2.

[0056] As shown in Figure 2 , the initial state of the clamp is that the swing frame 2 is horizontal and close to the base 1, and the clamping jaw 6 is open. When assembling the butterfly valve, an assembler first needs to place the butterfly valve body 100 in the cavity 31 of the rotating table 3, and at this time, the butterfly valve body 100 is placed horizontally; the assembler continues to place a valve disc into a flow channel opening on the butterfly valve body 100, and in the process of pressing down the valve disc, the clamping jaw 6 is closed to clamp the butterfly valve body 100, and at the same time, a control switch of the control assembly 5 is triggered, the position detector 4 starts to detect the position of the mounting surface 110, then the rotating table 3 is rotated to make the mounting surface 110 face away from the side, away from the hinged position of the swing frame 2, then the swing frame 2 swings upward to a vertical position, at this time, the mounting surface 110 is located at the top of the butterfly valve body 100; the assembler continues to insert the rotating shaft from the mounting surface 110, in the process of insertion, the control switch of the control assembly 5 is triggered, the swing frame 2 swings downward in the reverse direction, and when the swing frame 2 is lowered to be horizontal, the clamping jaw 6 is loosened, the assembler takes down the butterfly valve body 100, and the assembling process of the butterfly valve is completed.

[0057] Specifically, the position detector 4 can be a camera, which can be arranged on each of the four sides of the butterfly valve body 100, and the position of the mounting surface 110 can be determined by the program after the image of the corresponding side is obtained; the control switch of the control assembly 5 can be a pressure-sensitive switch, which is triggered once when the worker installs the valve disc and presses down, so that the rotating table 3 rotates and the swing frame 2 swings; the switch is triggered twice when the worker installs the rotating shaft and presses down, so that the swing frame 2 continues to swing. The switch can be set to be released, that is, the switch is triggered after the worker presses down and lifts up.

[0058] The butterfly valve assembly full-automatic clamp provided by the embodiment can make the rotating table 3 adjust the mounting surface 110 to the appropriate position when the worker installs the valve disc, and then the valve disc body 100 is erected by the swing frame 2, so that the worker can continue to install the rotating shaft, and the swing frame 2 continues to swing in the reverse direction to return to the initial position after the installation of the rotating shaft is completed, thereby avoiding the problem that the worker needs to repeatedly find the mounting surface 110 when assembling the butterfly valve.

[0059] Further, as shown in Figure 2 , the clamping jaw 6 has an "L" shape, and the two ends of the "L" shape form a clamping part 61 and a locking part 62, respectively. The connecting part of the clamping part 61 and the locking part 62 forms a swing part 63, the swing part 63 rotates and connects the rotating table 3, and the locking part 62 connects the rotating table 3 through the locking structure 64.

[0060] The swing of the locking part 62 can drive the clamping part 61 to swing, when the butterfly valve body 100 is placed and pressed down, the locking part 62 swings downward, thereby driving the clamping part 61 to swing in the direction of approaching the cavity 31, and then clamping the butterfly valve body 100, and locking through the locking structure 64.

[0061] Further, as shown in Figure 5 , the locking structure 64 includes a lock catch 641 and a lock hook 642.

[0062] The lock catch 641 is arranged at the bottom of the locking part 62.

[0063] The lock hook 642 is arranged on the rotating table 3 and is connected to the control assembly 5, and the lock hook 642 cooperates with the lock catch 641.

[0064] When the locking part 62 swings downward, the lock catch 641 at the bottom of the locking part 62 can be hooked by the lock hook 642, thereby limiting the movement of the locking part 62; when the switch of the control assembly 5 is triggered, the lock hook 642 moves, so that the lock catch 641 is separated from the lock hook 642, and the locking part 62 can return to the original position.

[0065] Further, as shown in Figure 2And Figure 5 In the embodiments provided in the present embodiment:

[0066] The two ends of the locking hook 642 are respectively bent to form a hooking portion 6421 and an abutting portion 6422.

[0067] The control assembly 5 includes a first driving member 51 arranged on the swing frame 2, which penetrates the rotating table 3 to abut against the abutting portion 6422.

[0068] The locking hook 642 can be an "L" shaped structure, the upper part of which forms the hooking portion 6421 for hooking the lock 641, and the lower part forms the abutting portion 6422, which can be pushed to swing upward by the first driving member 51, thereby driving the hooking portion 6421 to swing away from the lock 641, so that the lock 641 is released.

[0069] Further, please refer to Figure 5 In the embodiments provided in the present embodiment:

[0070] The rotating table 3 is provided with a receiving groove 32, and the locking hook 642 is located in the receiving groove 32. The bottom of the receiving groove 32 is provided with a through hole 321.

[0071] The first driving member 51 includes a top rod 511, which penetrates the through hole 321.

[0072] Specifically, the top rod 511 can be a telescopic rod. When the telescopic rod is elongated, the top end of the rod abuts against and pushes the abutting portion 6422, so that the abutting portion 6422 swings upward, and the lock 641 is released from the hooking portion 6421.

[0073] Further, each receiving groove 32 has two locking hooks 642, and the hooking portions 6421 of the two locking hooks 642 are respectively close to the two inner sides of the receiving groove 32, and the two abutting portions 6422 are transversely overlapped and located below the lock 641.

[0074] When the locking hook 642 moves downward, the two locking hooks 642 can hook the two sides of the locking hook 642 respectively; when the top rod 511 rises, the top rod 511 can abut against and push the two abutting portions 6422, so that the two hooking portions 6421 are relatively far away.

[0075] Further, please refer to Figures 2 to 4 The control assembly 5 further includes a second driving member 52, a third driving member 53 and a pressing control member 54.

[0076] The second driving member 52 is arranged on the swing frame 2 and connected to the rotating table 3.

[0077] The third driving member 53 is arranged on the base 1 and connected to the swing frame 2.

[0078] The pressing control 54 is arranged on the base 1 and below the hinged part of the swing frame 2, and is connected with the first driving member 51, the second driving member 52 and the third driving member 53.

[0079] The second driving member 52 and the third driving member 53 can be driving motors, and the pressing control 54 can be a pressure-sensitive switch. When the workers install the valve disc and the rotating shaft, the pressure-sensitive switch can be triggered by pressing.

[0080] Further, the cavity 31 is a groove structure, and the inner contour of the groove structure is adapted to the butterfly valve body 100, so that the workers can quickly place the butterfly valve body 100 in the appropriate position.

[0081] Further, the reset structure 7 arranged on the clamping jaw 6 is used to force the clamping part 61 to move away from the cavity 31. That is, when the locking part 62 is unlocked, the locking part 62 can be driven to swing upward, so that the clamping parts 61 on both sides of the cavity 31 move away from each other, thereby releasing the butterfly valve body 100.

[0082] Further, referring to Figure 5 , the reset structure 7 includes a spring arranged on the abutting part 6422. When the hooking part 6421 releases the lock 641, the spring can push the lock 641 to force the locking part 62 to swing upward.
