[0016] S1: Clamping process: control the first motor to work so that the output shaft of the first motor rotates, and the rotation of the output shaft of the first motor drives the stud to rotate, and the rotation of the stud drives the threaded blocks on both sides to move relative to each other, and the threaded blocks on both sides can drive the clamping plates on both sides to move synchronously, so that the clamping plates on both sides clamp and fix the high-pressure pump body, and when the clamping plates on both sides move, the two second sliders can be driven to slide on the outer walls of the second slide rods on both sides.

At the same time, the rotating part of the tightening machine and the bolt are driven downward by the action of the vertical plate to make the bolt fit with the threaded hole of the end cover. Control the tightening machine to work, so that the rotating part of the tightening machine drives the bolt to rotate. While the tightening machine moves downward, the rotating part of the tightening machine rotates, so that the bolt can fix the end cover and the high-pressure pump body tightly, and can be sealed by a rubber pad. According to the above operations, the end cover and the high-pressure pump body are fixed by multiple sets of bolts.

[0019] S4: Material unloading process: After the sealing process of the high-pressure pump body is completed, according to the above operation, the output shaft of the first motor is controlled to rotate in the opposite direction, so that the clamping plates on both sides no longer clamp the high-pressure pump body, and the third motor is controlled to work, so that the output shaft of the third motor rotates to drive the first connecting rod to rotate, so that the other end of the first connecting rod pulls one end of the second connecting rod to move upward through the pin shaft, so that the other end of the second connecting rod pulls the push plate on one side to move, and the movement of the push plate on one side can drive the push plate on the other side to move synchronously through two groups of cylinders and two cross bars.

While the clamping plates on both sides move, the two second sliding blocks can be driven to slide on the outer walls of the second sliding rods on both sides, so that the position of the high-pressure pump body can be fixed and the transportation distance can be fixed, so that the position of the high-pressure pump after transportation can correspond to the tightening machine more accurately, making the present invention more convenient to use.

[0022] Through the cooperation of the unloading device, the clamping device, the conveyor belt and the inclined plate, the output shaft of the first motor rotates in the opposite direction, so that the clamping plates on both sides no longer clamp the high-pressure pump body, and the third motor is controlled to work, so that the output shaft of the third motor rotates to drive the first connecting rod to rotate, so that the movement of the push plate on one side can drive the push plate on the other side to move synchronously through the two groups of cylinders and the two cross bars, and the push plates on both sides can move stably under the support of the support columns on both sides.

While the sleeve 202 rotates, the round rod 206 can drive the disc 207 to move inside the sleeve 202, so that the spring 208 is compressed. When the sleeve 202 moves past the vertical position, the spring 208 is no longer compressed, so that the cross plate 18 can move quickly. When the connecting block 204 moves to the groove on the surface of the workbench 1, the position of the cross plate 18 is fixed, and the second motor 201 is stopped.

[0039] S3: Sealing process: Control the three-stage robot arm to work, so that the three-stage robot arm, the robot arm base 22 and the clamping claw 17 cooperate to clamp the end cover and transport it to the surface of the high-pressure pump body where the end cover is installed, and the tightening machine 6 is transported to align with the threaded hole on the surface of the end cover through the first crossbeam 11 and the second crossbeam 5. At the same time, the rotating part of the tightening machine 6 and the bolt are driven downward by the action of the vertical plate 7 (the outer walls of the first crossbeam 11, the second crossbeam 5 and the vertical plate 7 are all equipped with power equipment for transmission), so that the bolt is fitted with the threaded hole of the end cover. , control the tightening machine 6 to work, so that the rotating part of the tightening machine 6 drives the bolt to rotate (the tightening machine 6 can install the screws through multiple sets of mechanical arms and clamps 17, and the rotating part of the tightening machine 6 has magnetic force, so that the bolt can be adsorbed to the surface of the rotating part). While the tightening machine 6 moves downward, the rotating part of the tightening machine 6 rotates, so that the bolt can fix the end cover and the high-pressure pump body tightly, and can be sealed by a rubber pad. According to the above operation, the end cover and the high-pressure pump body are fixed by multiple sets of bolts.

[0040] S4: blanking process: after the sealing process of the high-pressure pump body is completed, according to the above operation, the output shaft of the first motor 803 is controlled to rotate in the opposite direction, so that the clamping plates 803 on both sides no longer clamp the high-pressure pump body, and the third motor 906 is controlled to work, so that the output shaft of the third motor 906 rotates to drive the first connecting rod 907 to rotate, so that the other end of the first connecting rod 907 pulls one end of the second connecting rod 908 to move upward through the pin shaft, so that the other end of the second connecting rod 908 pulls the push plate 903 on one side to move, and the movement of the push plate 903 on one side can drive the push plate 903 on the other side to move synchronously through the two sets of cylinders 905 and the two cross bars 901 (while the clamping plates 801 on both sides are moving, the push plates 903 on both sides can be driven to move synchronously). The cross bar 901 slides inside the cylinder 905 on both sides), and the push plates 903 on both sides can move stably under the support of the support columns 904 on both sides. When the push plates 903 on both sides move to the openings on the surfaces of the clamping plates 801 on both sides, the third motor 906 is stopped, and the high-pressure pump body can be pushed to the surface of the inclined plate 21 under the push of the push plates 903 on both sides. Under the action of the inclined surface of the inclined plate 21, the high-pressure pump body can be made to slide to the surface of the conveyor belt 12, and the conveyor belt 12 is controlled to work, so that the conveyor belt 12 can transport the high-pressure pump after the sealing process is completed. According to the above operation, the output shaft of the second motor 201 is controlled to rotate in the opposite direction, so that the cross plate 18 returns to its original position, and the high-pressure pump body is placed again for further processing.

[0041] S5: Technical advantages: By fixing the position of the high-pressure pump body and the transportation distance, the position of the high-pressure pump after transportation can be more accurately matched with the tightening machine 6, making the present invention more convenient to use; the sleeve 202 is used for swinging transportation, and at the same time, a quick return effect can be achieved under the push of the spring 208, so that the cross plate 18 moves faster. Since the position of the high-pressure pump is fixed, the position of the high-pressure pump will not be affected after the quick return, so that the transportation time of the present invention is reduced and the work efficiency is improved; by pushing the processed high-pressure pump to the surface of the conveyor belt 12 for transportation, continuous processing of the high-pressure pump can be achieved, thereby improving the functionality of the present invention.
