[0035] In order to clearly describe the working principle of the present application, we take Figure 1For the azimuthal view, the azimuth refers to "up, down, left, right, front, back" appearing below, as follows: S1, the long steel plate on the external conveyor is clamped and transferred to the two groups of L-shaped plates 103 by the mechanical arm 105, the synchronous extension of the output ends of the two side cylinders 102 is controlled to make the two groups of L-shaped plates 103 close to each other, the pressing plate 104 rotates under the action of the external motor to press and contact the top of the long steel plate, the clamping effect is improved, and the phenomenon of long steel plate disengagement is avoided; S2, under the action of the output end of the upper first stepping motor 203, the upper pressing piece 206 is located directly above the left bending position of the long steel plate, and the output end of the upper first electric push rod 205 is stretched to make the upper pressing piece 206 fit the top of the long steel plate. Under the combined action of the output end of the lower first stepping motor 203 and the output end of the lower first electric push rod 205, the lower pressing piece 206 fits the bottom of the long steel plate and is located to the left of the upper pressing piece 206. The output end of the lower first electric push rod 205 is controlled to continue to stretch, so as to bend upward on the left side of the long steel plate, and similarly bend downward on the right side of the long steel plate, thereby forming a bent plate 603; S3, under the action of the extension of the output end of the fourth electric push rod 307, the supporting plate 308 moves upward to fit the bottom of the horizontal plate of the bent plate 603. Under the cooperation of the output end of the second stepping motor 303 and the output end of the third electric push rod 305, the drilling device is realized to open a mounting hole in the middle of the horizontal plate of the bent plate 603. After that, similarly, the cutting device opens a notch on the horizontal plate of the bent plate 603. Due to the support of the supporting plate 308, the adjusting plate 604 generated after cutting will not fall down. The mounting hole is located on the adjusting plate 604. Under the action of the output end of the upper first stepping motor 203, the upper pressing piece 206 is located directly above the adjusting plate 604. By controlling the extension of the output end of the second electric push rod 208, the downward movement of the pressing strip 207 is realized. The pressing strip 207 and the supporting plate 308 cooperate to clamp and fix the adjusting plate 604. After that, the output end of the fourth electric push rod 307 continues to stretch to drive the supporting plate 308 to move upward, while the output end of the second electric push rod 208 synchronously contracts to drive the pressing strip 207 to move upward. During this process, the adjusting plate 604 is always in a clamped state, so as to realize the upward movement of the clamped adjusting plate 604.

Finally, the mechanical arm 105 takes out the bent plate 603 and the adjusting plate 604 from the box body 101. S4, the pressing plate 104 is rotated to the vertical state under the action of the external motor, and the valve body 6 on the external conveyor is also transferred into the box body 101 through the mechanical arm 105, and is clamped by the two groups of L-shaped plates 103 approaching each other, and the valve cover 601 on the external conveyor is clamped and transferred to the top of the valve body 6 through the mechanical arm 105, the positioning plate 602 at the bottom of the valve cover 601 enters the valve body 6, and then the upper pressing piece 206 is attached to the top of the valve cover 601 to realize fixation. Similarly, under the cooperation of the output ends of the second stepper motor 303 and the third electric push rod 305, the drilling device and the tapping device form a small threaded hole at the four corner positions of the valve body 6 and the valve cover 601, and another set of drilling device and tapping device can form a large threaded hole in the middle of the valve cover 601; S5, the mechanical arm 105 takes out the valve body 6 from the box body 101 and transfers it to the first welding mechanism 4, controls the synchronous contraction of the two output ends of the first double-end cylinder 401 to make the two groups of first clamping pieces 402 approach each other to clamp and fix the valve body 6, and transfers the adjusting plate 604 to the second welding mechanism 5, controls the synchronous contraction of the two output ends of the second double-end cylinder 501 to make the two groups of second clamping pieces 502 approach each other to clamp and fix the adjusting plate 604, and also transfers the valve cover 601 to the second welding mechanism 5, controls the synchronous contraction of the two output ends of the third double-end cylinder 514 to make the two groups of third clamping pieces 515 approach each other to clamp and fix the valve cover 601, and the mechanical arm 105 also transfers the threaded rod 606 on the external conveyor between the two groups of fourth clamping pieces 524, the synchronous extension of the output ends of the tenth electric push rod 523 clamps and fixes the threaded rod 606, then the output end of the eighth electric push rod 503 extends to drive the supporting block 504 to move upward and contact the bottom of the adjusting plate 604, the mechanical arm 105 transfers the bearing 605 on the external conveyor to the mounting hole on the adjusting plate 604, because there is a supporting block 504, the bearing 605 will not fall, under the cooperation of the output ends of the fifth drive motor 505, the ninth electric push rod 509 and the sixth drive motor 512, the second welding head 511 is aligned with the connecting position of the outer ring of the bearing 605 and the adjusting plate 604, and rotates 360 degrees, so as to realize welding of the adjusting plate 604 and the outer ring of the bearing 605, and then under the cooperation of the output ends of the seventh drive motor 520 and the sixth stepper motor 518, the threaded rod 606 in the clamping state rotates and moves downward, so that the threaded rod 606 is twisted into the large threaded hole of the valve cover 601, and the bottom of the threaded rod 606 enters the inner ring of the bearing 605, and the second welding head 511 welds the bottom of the threaded rod 606 and the inner ring of the bearing 605; S6, while the step S5 occurs, the mechanical arm 105 transfers the processed bending plate 603 to the inside of the valve body 6, aligns the bending plate 603 and the valve body 6 connection by the first welding head 415 and carries out welding, after that, the mechanical arm 105 transfers the valve cover 601, threaded rod 606, bearing 605 and adjusting plate 604 connected together as a whole, so that the valve cover 601 is located at the top of the valve body 6, the positioning plate 602 at the bottom of the valve cover 601 enters into the valve body 6, after that, the mechanical arm 105 transfers the rotating wheel 607 on the external conveyor to the top of the threaded rod 606, aligns the rotating wheel 607 and the threaded rod 606 connection by the first welding head 415, and carries out rotary welding, so as to realize the automatic processing of the flow valve, without manual operation.
