[0018] Embodiment 1

[0019] Please refer to Figure 1-Figure 5 A machine tool profiling turning mechanism comprises a processing seat 1 and two mounting plates 2 fixedly connected to the top of the processing seat 1, two slide rails 5 are fixedly installed between the mounting plates 2, a turning assembly is arranged on the left mounting plate 2, a driving assembly is arranged on the right mounting plate 2, an adaptive clamping assembly 6 is arranged on the slide rail 5, and the driving assembly is used to drive the adaptive clamping assembly 6 to move transversely along the slide rail 5;

[0020] The adaptive clamping assembly 6 includes a slider 60 slidably mounted on the slide rail 5, a fixed plate 61 is fixedly connected to the top of the slider 60, a clamping seat 62 is fixedly mounted on the inner side of the fixed plate 61, a movable groove 63 is provided on the inner side of the clamping seat 62, a plurality of clamping arms 64 are slidably mounted in the movable groove 63, and the clamping arms 64 are used to clamp the side wall of the circular tube workpiece, a limiting groove 65 is provided on the inner side of the fixed plate 61, and an adjusting assembly for adjusting the clamping force is provided inside the limiting groove 65, and the adjusting assembly is used to adjust the clamping force during turning of circular tubes of different diameters, and the adjusting assembly includes an electromagnet 6 fixedly connected to the center of the limiting groove 65 6. Several fixed sleeves 67 corresponding to the clamping arm 64 are fixedly installed on the outer side of the electromagnet 66. A magnetic slide bar 68 is slidably installed on the outer side of the fixed sleeve 67. The magnetic slide bar 68 is fixedly connected to the clamping arm 64. The adjustment component also includes a spring 69 fixedly connected to the outer side of the magnetic slide bar 68. The other end of the spring 69 is fixedly installed with a piezoelectric ceramic piece 610. The electrical signal output end of the piezoelectric ceramic piece 610 is provided with an electrical signal amplifier for detecting a pressure signal. The turning component includes a motor 3 fixedly connected to the left mounting plate 2. The output end of the motor 3 is installed with a turning tool 7. The driving component includes a cylinder 4 fixedly connected to the right mounting plate 2. The output end of the cylinder 4 is fixedly connected to the side wall of the slider 60. Before the circular tube is processed, the cylinder 4 controls the slider 60 to move right, and then the circular tube is installed in the clamping arm 64. The electromagnet 66 is then turned on along the arc-shaped inner wall of the clamping arm 64. Under the action of the magnetic adsorption force between the electromagnet 66 and the magnetic slide bar 68, the clamping arm 64 is driven to clamp and limit the outer wall of the circular tube. At this time, the spring 69 is compressed, and an electrical signal is generated on the piezoelectric ceramic sheet 610. The current of the electromagnet 66 is adjusted according to the diameter of the circular tube. When the current is larger, the sliding amplitude of the clamping arm 64 is larger to adapt to the clamping of the circular tube with a smaller diameter. When the current is smaller, the clamping The smaller the sliding amplitude of the arm 64 is, the smaller it is to adapt to the clamping of circular tubes with larger diameters. When the current of the electromagnet 66 is adjusted until the surface pressure of the piezoelectric ceramic sheet 610 is consistent, it means that the clamping force of the clamping arm 64 is constant, thereby achieving the goal that during the turning process of circular tubes of different diameters, the clamping force of the tube wall always remains constant, thereby reducing the defective rate of the circular tube workpiece during turning and improving the processing quality of the circular tube workpiece. After the adaptive clamping of the workpiece is completed, the cylinder 4 controls the slider 60 to move left, so that the workpiece contacts the turning tool 7 to realize the turning process. After the processing is completed, the cylinder 4 controls the slider 60 to move right again, turns off the electromagnet 66, and removes the processed workpiece.

[0021] As a preferred technical solution of this embodiment, the center of the turning tool 7 and the center of the movable groove 63 are located on a straight line in the same horizontal plane, ensuring that the turning tool 7 acts on the center of the circular tube to perform turning processing on the workpiece.

The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
