[0023] Specifically, the floating component 7 includes a connecting seat 71 and a rotating block 72 rotating in the connecting seat 71, and a floating plate 73 fixed on the rotating block 72. The floating plate 73 also rotates in the connecting seat 71. Springs 74 are provided between the upper and lower ends of the floating plate 73 and the inner side of the connecting seat 71. In this embodiment, the floating component 7 can automatically increase the fit according to the shape of the blade clamping position, which can not only ensure the clamping reliability, but also avoid indentations at the clamping position, thereby ensuring the quality of the blade.

[0024] Specifically, the X-axis quick-adjustment mechanism 3 includes an internally threaded slider 31 fixed to the bottom of the support plate 2 and sliding in the base 1, a bidirectional lead screw 32 rotating in the base 1, and a quick-adjustment motor 33 installed on one side of the base 1. The output end of the quick-adjustment motor 33 is provided with a transmission assembly 34 for driving the bidirectional lead screw 32 to rotate. In this embodiment, the Z-axis quick-adjustment mechanism 3 has the advantages of a large adjustment range and a high speed, and can adapt to the positioning work of blade processing of different sizes and models.

[0025] Specifically, the X-axis fine-tuning mechanism 4 includes an X-axis slide rail 41 fixed on the support plate 2, an X-axis lead screw 42 rotatably installed in the X-axis slide rail 41, and an X-axis slider 43 sliding inside the X-axis slide rail 41 and threadedly connected to the X-axis lead screw 42. It also includes an X-axis motor 44 fixed on one side of the X-axis slide rail 41 and the output end of which is connected to the X-axis lead screw 42.

Then, according to the blade shape, the positions of the clamping mechanisms 6 are adjusted through the Z-axis fine adjustment mechanism 4 and the X-axis adjustment mechanism 5, so that the lower ends of the corresponding points of the blade are supported on the clamping plate 62. Under the action of the floating component 7, the clamping plate 62 increases the contact surface with the bottom of the opposite-direction blade. Then, the clamping cylinder 63 pushes one end of the clamping rod 64 upward, and the clamping block 65 clamps the blade at a position directly above the clamping plate 62. At this time, the clamping block 65 is automatically adjusted according to the shape of the upper end of the blade clamping position through the floating component 7. During the adjustment process, the rotating block 72 and the floating plate 73 rotate inside the connecting seat 71, and the floating plate 73 is deformed.

[0030] The use of the Z-axis quick adjustment mechanism 3, the Z-axis fine adjustment mechanism 4, and the X-axis adjustment mechanism 5 is as follows: the transmission assembly 34 is driven by the forward and reverse rotation of the quick adjustment motor 33 and the bidirectional lead screw 32 is driven, and the internal threaded slider 31 drives the support plate 2 and its upper end connecting piece to move synchronously through the spiral of the bidirectional lead screw 32, and the support plates 2 at both ends move synchronously in different directions; the Z-axis lead screw 42 is driven by the forward and reverse rotation of the Z-axis motor 44 and the Z-axis slider 43 is driven to move in the Z-axis slide rail 41 to change the position of the X-axis adjustment mechanism 5 and the clamping mechanism 6 and the floating component 7; the X-axis lead screw 52 is driven by the forward and reverse rotation of the X-axis motor 54 and the X-axis slider 53 is driven to move in the X-axis slide rail 51, thereby adjusting the position of the clamping mechanism 6 and the floating component 7.
