[0036] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0037] Embodiment 1

[0038] like Figures 1 to 13 As shown, an automobile pump body assembly parts assembly system includes a support frame 1, a bearing assembly mechanism 13, a rotating shaft assembly mechanism 14, and a water seal assembly mechanism 15, characterized in that a loading frame 3 is sleeved on the support frame 1, and the bearing assembly mechanism 13, the rotating shaft assembly mechanism 14, and the water seal assembly mechanism 15 all include a hydraulic press 2 arranged above the support frame 1, a pressing port 4 and a clamping structure arranged in the pressing port 4 are arranged below the hydraulic press 2, and the clamping structure includes a clamping hand a131 of the bearing assembly mechanism 13 for clamping the bearing 130, a clamping hand b141 of the rotating shaft assembly mechanism 14 for clamping the rotating shaft 140, and a clamping hand c151 of the water seal assembly mechanism 15 for clamping the water seal 150, and sliding devices are arranged on both sides of the pressing port 4. A receiving plate 6 is provided, and the contact surfaces of the gripping structure and the receiving plate 6 are attracted to each other by magnetism. A slide rail 7 for driving the gripping structure to move is provided in the pressing port 4. A groove 8 and an electromagnet 9 provided in the groove 8 are provided on the side of the pressing port 4. A receiving port 11 is provided on the loading rack 3. When the hydraulic press 2 presses down and drives the base to descend, the gripping structure and the receiving plate 6 are also driven down. During the descent of the gripping structure, the gripping structure moves toward the center under the action of the slide rail 7 to center the parts. During the descent of the receiving plate 6, the electromagnet 9 moves and separates from the parts. A plurality of air blowing holes 12 are provided on the surface of the receiving plate 6. The air blowing holes 12 are used for air blowing cleaning of the gripping structure on the other side during the ascent of the gripping structure.

[0039] In addition, the pump body assembly components are composed of a base, bearings, connecting rods, and water seals. A manipulator for taking and placing materials is provided on one side of the support frame. The base is placed on the loading rack first, and the bearings, connecting rods, and water seals are assembled in sequence by rotating clockwise. The clamps set for components in different positions are adjusted accordingly. After the manipulator places the base on the receiving port, it rotates the loading rack so that the receiving port coincides with the pressing port. The manipulator places the material to be assembled in the pressing port, and the hydraulic press presses down to drive the components to move downward, and the components drive the receiving plate to move downward. During the downward movement of the clamp, it moves under the action of the slide rail to center and clamp the components. The receiving plate drives the clamp downward through magnetism. During the downward movement of the receiving plate, when the component is about to approach the base, the electromagnet is energized to suck the receiving plate into the receiving slot through magnetism, and the hydraulic press continues to press down to press the component from the clamp into the base.

[0040] like Figure 1 , Figure 8As shown, an air blowing channel 21 connected to the air blowing hole 12 is opened in the receiving plate 6, and a piston cylinder 22 connected to the air blowing channel 21 is arranged on the surface of the receiving plate 6. A piston 23 and a piston rod 24 slidably arranged on the piston 23 are slidably arranged in the piston cylinder 22. A spring is arranged between the piston 23 and the inner wall of the piston cylinder 22, and the piston rod 24 is slidably arranged on the surface of the slide rail 7. A servo motor 26 is arranged on the support frame 1, and a belt 26 is sleeved between the servo motor 25 and the loading frame 3.

[0041] It is worth mentioning here that after the hydraulic press 2 completes the pressing, the pressure rod of the hydraulic press 2 rises, thereby causing the clamp 5 to rise and reset. During the rising process of the clamp 5, the piston rod 24 is driven to move under the action of the slide rail 7, and the piston rod 24 drives the piston 23 to move. While the piston 23 moves, air is pumped into the air blowing channel 21, so that the air blowing hole 12 blows air to the clamp on the other side, thereby cleaning the surface of the clamp to prevent adhesion of debris that affects the subsequent centering accuracy.

[0042] like Figure 8 , Fig. 9 As shown, slide grooves 31 are opened on both sides of the pressing port 4, a fixed rod 32 is arranged in the slide groove 31, a slide rod 33 is slidably arranged on the fixed rod 32, a support rod 34 is arranged on the side of the clamping structure, the support rod 34 is slidably arranged in the slide rod 33, a push rod 35 is arranged on the side of the clamping structure, the slide rails 7 are arranged on both sides of the slide groove 31, and the push rod 35 is slidably arranged on the surface of the slide rail 7.

[0043] It is noted here that the width of the slide groove 31 is the same as the width of the slide rod 33, which prevents the clamping hand 5 from shaking during movement. The clamping hand 5 drives the slide rod 33 to descend as it descends. At the same time, the push rod 35 moves toward the center under the action of the slide rail 7 to center the parts and clamp them so that the parts and the base are on the same axis.

[0044] like Figure 5 As shown, a slider 41 is slidably provided at the upper end of the groove 8, a connecting rod 42 is provided at the lower end of the slider 41, the receiving plate 6 is slidably provided on the connecting rod 42, and a receiving groove 43 for accommodating the receiving plate 6 is provided at the bottom of the pressing port 4.

[0045] It is worth mentioning here that when the receiving plate 6 descends and slides on the connecting rod 42, the electromagnet 9 is energized when passing the sensor to make the receiving plate 6 separate from the components and drive the slider 41 to slide, thereby improving the sliding stability of the receiving plate 6 and keeping the receiving plate moving in the center at all times.

[0046] like Figure 2 As shown, the diameters of the pressing port 4 and the receiving port 11 are equal, and the center distances from the pressing port 4 and the receiving port 11 to the central axis of the loading rack 3 are equal.

[0047] It is worth mentioning that by making the center distances from the pressing port 4 and the receiving port 11 to the central axis of the loading rack 3 equal, the pressing port 4 can be moved to the bottom of the receiving port 11 so as to coincide with the axis of the receiving port 11, and the gripper 5 in the receiving port 11 can be centered so that the parts coincide with the axis of the base.

[0048] like Figure 3 As shown, the contact surface between the piston rod 24 and the slide rail 7 is configured to be semicircular.

[0049] In addition, the contact surface between the piston rod 24 and the slide rail 7 is set to be semicircular, which can reduce the friction between the piston rod 24 and the slide rail 7 and make the sliding smoother.

[0050] like Fig. 9 As shown, a spring is arranged between the support rod 34 and the inner wall surface of the slide rod 33 , and a spring sleeved on the fixed rod 32 is arranged between the slide groove 31 and the slide rod 33 .

[0051] It is worth mentioning here that by setting a spring, the support rod 34 can be reset by the spring during the reset process after the hydraulic press is pressed, thereby driving the clamping hand 5 to reset and prepare for the next clamping. At the same time, the slide rod 33 can be raised and reset, thereby driving the receiving plate 6 to reset.

[0052] like Figure 5 As shown, a spring is provided between the slider 41 and the end surface of the groove 8 .

[0053] It is worth mentioning that by providing a spring between the slider 41 and the end surface of the groove 8, the receiving plate 6 can be reset along with the gripper 5 while the slider 41 is reset under the action of the spring, thereby driving the receiving plates 6 on both sides to close.

[0054] like Figure 8 As shown, the air blowing hole 12 is arranged to be inclined downward by 30-45 degrees.

[0055] It is worth mentioning here that by tilting the air blowing hole 12 downward by 30-45 degrees, the air blowing hole 12 can face the surface of the clamp 5 on the other side, so that when the air blowing hole 12 is blowing, the surface of the clamp 5 can be cleaned to prevent debris from adhering to the surface of the clamp 5 and affecting the centering accuracy.

[0056] like Figure 5 As shown, the thickness of the accommodating groove 43 is greater than the thickness of the receiving plate 6 .

[0057] In addition, by making the thickness of the receiving groove 43 higher than the thickness of the receiving plate 6 , the receiving plate 6 can be prevented from being too narrow in the receiving groove 43 and failing to suck the receiving plate 6 into the receiving groove 43 when the electromagnet 9 is energized during the process of the receiving plate 6 descending.
