The use of the vertical multistage pump automatic assembly line is a system device that can greatly improve the production efficiency and product quality of vertical multistage pumps, while reducing labor costs and production risks.

[0003] In the process of assembling the vertical multistage pump using the automatic assembly production line, the workpiece at the end position of the vertical multistage pump needs to be stably placed on the moving conveyor plate of the automatic assembly production line, and then the moving conveyor plate on the automatic assembly production line drives the vertical multistage pump workpiece at its upper end to move to the appropriate position, so that the automatic assembly robot arm can assemble other vertical multistage pump workpieces step by step.

[0004] However, when the workpieces of the vertical multistage pump are assembled layer by layer, the height of the vertical multistage pump also increases with the assembly of the workpieces, and the weight of the vertical multistage pump after the step-by-step assembly increases significantly, and the centrifugal force of the vertical multistage pump gradually increases. Then, when the vertical multistage pump is transported and moved on the automatic assembly production line, its center of gravity is shifted by external force, and the vertical multistage pump is easy to tilt and fall sideways from the automatic assembly production line, causing a certain degree of damage to the vertical multistage pump automatic assembly production line, and easily affecting the normal operation of the vertical multistage pump automatic assembly production line. Therefore, a vertical multistage pump automatic assembly production line is proposed to address the above problems. Utility Model Content

As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form.

[0025] See also Figure 1-6 , the utility model provides a technical solution:

[0026] A vertical multi-stage pump automatic assembly production line comprises a device box 1, a track 2, a slide rail 3 and a conveying plate 4, wherein the track 2 is fixedly connected to the outer side of the device box 1, the slide rail 3 is slidably connected to the outer side of the track 2, the outer side of the slide rail 3 is fixedly connected to a surrounding frame 41, the outer side of the conveying plate 4 is fixedly connected to the surrounding frame 41, the side of the conveying plate 4 away from the surrounding frame 41 is fixedly connected to a dual-axis stepping motor 5, the outer side of the dual-axis stepping motor 5 is fixedly connected to the end of the main shaft, the outer side of the threaded shaft 51 is spirally connected to a fixed block 6, the outer side of the fixed block 6 is fixedly connected to a fixed plate 61, the other side of the fixed plate 61 is fixedly connected to a connecting column 62, the outer side of the connecting column 62 is slidably connected to a rotating drum 621, the other end of the connecting column 62 is fixedly connected to a slide plate 63, the outer side of the slide plate 63 is fixedly connected to a connecting plate 64, the outer side of the connecting plate 64 is fixedly connected to a rubber plate 641, and the outer side of the connecting plate 64 is fixedly connected to a limiting clamping plate 65.

[0027] As a further implementation of the present invention, two connecting posts 62 are symmetrically provided on the same side of the fixed plate 61, and the same side of the conveying plate 4 is symmetrically and tightly attached to the two fixed plates 61, which can ensure that the slide plate 63 always maintains horizontal linear motion.

[0028] As a further implementation scheme of the present invention, a slide groove is provided on the inner side of the conveying plate 4, and the rotating drum 621 slides in the slide groove opened on the inner side of the conveying plate 4. The height of the rotating drum 621 is much smaller than the thickness of the conveying plate 4, which can reduce the friction resistance of the connecting column 62 sliding on the inner side of the conveying plate 4.

[0029] As a further implementation of the present scheme, the fixed plate 61 and the slide plate 63 are parallel to each other on the same vertical plane, the slide plate 63 and the connecting plate 64 are perpendicular to each other, the connecting plate 64 and the limiting card plate 65 are perpendicular to each other, and the slide plate 63 is tightly attached to the side of the conveying plate 4 away from the fixed block 6, so that the limiting card plate 65 can fix and limit the assembly workpiece at the bottom of the vertical multi-stage pump placed on the conveying plate 4, so that the assembly workpieces of other vertical multi-stage pumps can be assembled step by step in the future.

[0030] As a further implementation scheme of the present invention, the limit card plate 65 is symmetrically arranged directly above the conveying plate 4. The limit card plate 65 is arranged on the opposite side of the two connecting plates 64 on the same conveying plate 4. Under the joint action of the two limit card plates 65, the assembly workpiece at the end of the vertical multi-stage pump can be fixed and restricted on the conveying plate 4.

[0031] As a further implementation of the present scheme, a rubber plate 641 is arranged directly below the limiting card plate 65, and the rubber plate 641 and the slide plate 63 are respectively arranged on both sides of the connecting plate 64. The rubber plate 641 can increase the limiting friction force between the connecting plate 64 and the workpiece at the end of the vertical multi-stage pump when the connecting plate 64 is used to fix the workpiece at the end of the vertical multi-stage pump.

[0032] As a further implementation scheme of the present scheme, the threaded shaft 51 and the screw direction of the thread set on its outer side are symmetrical with the other threaded shaft 51 and the screw direction of the thread set on its outer side on the same dual-axis stepper motor 5, and the threaded holes respectively opened on the inner sides of the two fixed blocks 6 under the conveying plate 4 are completely symmetrical with the center of the dual-axis stepper motor 5, so as to facilitate the simultaneous control of the two limit clamps 65 to move in relative or opposite directions at the same time.

[0033] Workflow: During use, the equipment is powered by an external power supply. During the process of assembling the vertical multistage pump using the vertical multistage pump automatic assembly production line, an assembly workpiece at the end of the vertical multistage pump is accurately placed at the center of the two slides 63 on the conveying plate 4 using an external device, and then the dual-axis stepper motor 5 fixedly connected under the conveying plate 4 is started. The operation of the dual-axis stepper motor 5 simultaneously controls the rotation of the threaded shafts 51 on both sides thereof, and the two threaded shafts 51 are respectively spirally connected to the two fixed blocks 6 under the conveying plate 4, so that the two threaded shafts with opposite spiral directions are When the stepper motor 51 rotates, the two fixed blocks 6 can be controlled to move in the direction of the dual-axis stepper motor 5 at the same time. When the fixed block 6 moves, the fixed block 6 can drive the fixed plate 61 fixedly connected to the outside thereof to slide closely under the conveying plate 4. The fixed plate 61 is fixedly connected to the slide plate 63 closely attached to the other side of the conveying plate 4 through the connecting column 62. At the same time, a rotating drum 621 is fixedly connected to the outside of the connecting column 62. When the fixed plate 61 drives the slide plate 63 to move on both sides of the conveying plate 4 through the connecting column 62, the rotating drum 621 can slide in the slide groove provided on the inner side of the conveying plate 4. 21 can effectively reduce the friction force of the connecting column 62 sliding on the inner side of the conveying plate 4. When the slide plate 63 passively moves close to the conveying plate 4, the slide plate 63 can drive the limiting card plate 65 to move toward the vertical multistage pump placed on the conveying plate 4 through the connecting plate 64, until the rubber plate 641 fixedly connected to the outer side of the connecting plate 64 is in close contact with the end assembly workpiece of the vertical multistage pump. At this time, the end assembly workpiece of the vertical multistage pump is clamped and fixed by the two connecting plates 64, and the rubber plate 641 fixedly connected to the connecting plate 64 can increase the clamping force between the connecting plate 64 and the end assembly workpiece of the vertical multistage pump. The combined friction force makes the rubber plate 641 on the outside of the connecting plate 64 tightly attached to the end assembly workpiece of the vertical multistage pump, and the limit clamping plate 65 fixedly connected to the connecting plate 64 is then clamped on the end assembly workpiece of the vertical multistage pump, so that when the center of gravity of the vertical multistage pump being transported and moved on the automatic assembly production line is shifted by the external force, the end assembly workpiece of the vertical multistage pump is not easy to tilt and fall from the automatic assembly production line, which effectively avoids the vertical multistage pump from tipping over and causing a certain degree of damage to the vertical multistage pump automatic assembly production line, thereby ensuring the normal operation of the vertical multistage pump automatic assembly production line.
