[0023] See also Figure 1-8 On the basis of the above embodiment, in another embodiment of the present invention, a clamping device and a limiting device are arranged on the top of the machine tool 1, wherein the clamping device comprises: a support rod 71, a cylinder 72, a rotating rod 73, an arc rod 74, an A clamping plate 75, a B clamping plate 76 and a No. 1 spring 77, the support rod 71 is fixedly mounted on the top of the turntable 5, the cylinder 72 is rotatably mounted on the top of the support rod 71, the rotating rod 73 is fixedly mounted on the circumferential surface of the cylinder 72, one end of the arc rod 74 is fixedly mounted on the top of the cylinder 72, the A clamping plate 75 is fixedly mounted on the other end of the arc rod 74, and the B clamping plate 76 is connected to the A clamping plate 75 by a No. 1 spring 77 to prevent the metal from being displaced during welding, thereby affecting the structural strength of the metal and ensuring the stability of the work.

[0024] A spring 77 is arranged between the A clamping plate 75 and the B clamping plate 76 . The rotating rod 73 itself is arranged as an arc surface. A limiting groove is arranged on the surface of the supporting rod 71 .

[0025] The clamping device also includes: a pushing block 78, a connecting rod 79 and a telescopic rod 710. The pushing block 78 passes through and is slidably installed on the inner and outer walls of the A clamp 75, the connecting rod 79 is fixedly installed at the bottom of the arc rod 74, and the telescopic rod 710 passes through and is slidably installed on the surface of the connecting rod 79, so as to prevent excessive clamping of the metal from causing deformation of the metal during welding and damage to the metal, thereby improving the protection of the metal.

[0026] The pushing block 78 contacts the telescopic rod 710 , and the telescopic rod 710 contacts the limiting groove.

[0027] The limiting device includes: a transmission column 81, a limiting rod 82, an L-shaped rod 83, a long rod 84, a reset rod 85, a handle 86 and a limiting block 87. The transmission column 81 is fixedly mounted on the surface of the cylinder 72, the limiting rod 82 is rotatably mounted on the outer wall of the transmission column 81, and the limiting rod 82 penetrates and is slidably mounted on the surface of the turntable 5, so that the turntable 5 cannot rotate when the metal is welded, thereby preventing the turntable 5 from rotating during welding and causing metal damage, thereby improving the stability of production. The L-shaped rod 83 is fixedly mounted on the surface of the limiting rod 82, the long rod 84 penetrates and is rotatably mounted on the inner wall of the turntable 5, the reset rod 85 is fixedly mounted on the circumferential surface of the long rod 84, the handle 86 is fixedly mounted on the end of the long rod 84 away from the limiting rod 82, and the limiting block 87 is fixedly mounted on the top of the output end of the linear motor 3, so that when a special situation occurs, the turntable 5 can also be adjusted when it is necessary to rotate, thereby improving the practicality of the device.

After the limit rod 82 is limited, the turntable 5 cannot continue to rotate, so that when welding the metal, the turntable 5 cannot rotate, thereby preventing the turntable 5 from rotating during welding and causing damage to the metal. The stability of production is improved. The handle 86 is pushed toward the metal direction. The movement of the handle 86 drives the long rod 84 to move. The movement of the long rod 84 drives the reset rod 85 to move. The reset rod 85 moves and is stuck in the L-shaped rod 83. Then the handle 86 is turned. The rotation of the handle 86 drives the long rod 84 to rotate. The rotation of the long rod 84 drives the reset rod 85 to rotate. The rotation of the reset rod 85 drives the L-shaped rod 83 to move toward the top. The movement of the L-shaped rod 83 drives the limit rod 82 to move. The movement of the limit rod 82 releases the limit on the limit block 87, so that when a special situation occurs, the turntable 5 needs to be rotated for adjustment, thereby improving the practicability of the device.
