[0002] A water pump is a machine that transports liquids or increases the pressure of liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. It can also transport liquid and gas mixtures and liquids containing suspended solids. The technical parameters of water pump performance include flow rate, suction head, head, shaft power, water power, efficiency, etc.; according to different working principles, it can be divided into volumetric water pumps, vane pumps and other types.

[0003] Most pump casings are made using casting technology. Since the surface of the pump casing after casting has burrs and the surface smoothness is poor, the pump casing needs to be polished after casting to increase the smoothness of the pump casing surface. In the existing technology, when polishing the cast pump casing, the cast pump casing matrix is ​​usually placed on a loading table, and then a robotic arm is used to clamp the cast pump casing on the loading table, and the robotic arm clamps the cast pump casing and moves it to the grinder for polishing.

[0004] In the process of implementing this application, the inventors found that there are at least the following problems in this technology: most of the existing loading tables for placing cast pump casings have simple structures, and it is inconvenient to adjust the position of the loading table, which results in poor coordination of the robotic arm when clamping the cast pump casing, thereby reducing the loading efficiency.

[0031] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0032] An embodiment of the present application discloses a loading and positioning platform for polishing a cast pump casing.

[0033] Reference Figure 1 A loading and positioning platform for polishing cast pump casings includes a support frame 1, a loading platform 2 and an adjusting mechanism 3. The loading platform 2 is arranged on the support frame 1. The support frame 1 includes a base frame 11, a top frame 12, a support column 13 and a lifting mechanism 14. The top frame 12 is arranged above the base frame 11. There are four support columns 13. The four support columns 13 are evenly installed at the four corners between the base frame 11 and the top frame 12. The lifting mechanism 14 is arranged between the two support columns 13 on the same side. The height of the support frame 1 can be adjusted by the lifting mechanism 14.

[0034] Reference Figure 1 and Figure 2The lifting mechanism 14 includes a bidirectional screw 141, a motor 142, a synchronization component 143, a movable block 144 and a support rod 145. The bidirectional screw 141 is rotatably mounted between the two support columns 13 on the same side. The motor 142 is fixedly mounted on one of the support columns 13, and the output end of the motor 142 is fixedly connected to one of the bidirectional screws 141. The synchronization component 143 includes a synchronization wheel 1431 and a synchronization belt 1432. The synchronization wheel 1431 is fixedly mounted on the end of the bidirectional screw 141. The two synchronization wheels 1431 are linked by the synchronization belt 1432. There are two symmetrical movable blocks 144 on the threaded sleeve of the bidirectional screw 141. The support rod 1 45 is hinged on the movable block 144 and the top frame 12 bracket, and a guide rod 146 is arranged parallel to the bottom of the bidirectional screw 141. The two ends of the guide rod 146 are fixedly connected to the support column 13, and the movable block 144 is slidably sleeved on the guide rod 146. Through the setting of the lifting mechanism 14, when in use, the motor 142 can be started to drive one of the bidirectional screws 141 to rotate, so that the two bidirectional screws 141 rotate synchronously through the synchronization component 143, so that the two bidirectional screws 141 drive their respective two movable blocks 144 to move closer to or away from each other, so that the movable block 144 drives the top frame 12 to move up and down through the support rod 145, so that the height of the loading platform 2 can be adjusted.

[0035] Specifically, the support column 13 includes a sleeve 131 and a sleeve rod 132 that slide together. The lower end of the sleeve 131 is fixedly connected to the base frame 11, and the upper end of the sleeve rod 132 is fixedly connected to the top frame 12. Through the cooperation between the sleeve 131 and the sleeve rod 132, when the top frame 12 is raised or lowered, the sleeve rod 132 can be extended and retracted along the sleeve 131, thereby playing a role of limiting support for the top frame 12 and improving the stability of the top frame 12.

The support plate 21 is slidably installed on the top frame 12, and the positioning plate 22 is installed above the support plate 21.

The casting pump casing is positioned by the positioning rod, so that the casting pump casing can be neatly arranged on the positioning plate 22 for loading.

[0037] Among them, spring airbags 25 are fixedly connected at the four corners between the support plate 21 and the positioning plate 22. Through the setting of the spring airbags 25, the positioning plate 22 can be elastically supported to avoid rigid extrusion of the positioning plate 22 when the robotic arm contacts the cast pump casing.

[0038] Reference Figure 3 and Figure 4The adjusting mechanism 3 includes a cylinder 31, a connecting frame 32 and a guide column 33. The cylinder 31 and the guide column 33 are all arranged horizontally.

A limit block 34 is fixedly mounted on the end of the top frame 12 away from the cylinder 31. Through the setting of the adjusting mechanism 3, when loading, the cylinder 31 can be started to drive the connecting frame 32 to move, so that the connecting frame 32 drives the support plate 21 to slide along the guide column 33, thereby facilitating the adjustment of the position of the loading platform 2, improving the coordination of the robot arm when clamping the casting pump casing, and thus improving the loading efficiency.

[0039] The implementation principle of the present application is as follows: the cast pump casing can be placed on the positioning plate 22, and the positioning rod can be inserted into the positioning hole 24. The cast pump casing can be positioned by the positioning rod, so that the cast pump casing can be neatly arranged on the positioning plate 22 for loading. When loading, the cylinder 31 can be started to drive the connecting frame 32 to move, so that the connecting frame 32 drives the support plate 21 to slide along the guide column 33, thereby facilitating the adjustment of the position of the loading platform 2, and improving the coordination of the robotic arm when clamping the cast pump casing, thereby improving the loading efficiency; when in use, the motor 142 can also be started to drive one of the bidirectional screws 141 to rotate, so that the two bidirectional screws 141 rotate synchronously through the synchronization component 143, so that the two bidirectional screws 141 drive their respective two movable blocks 144 to approach or move away from each other, so that the movable block 144 drives the top frame 12 to rise and fall through the support rod 145, so that the height of the loading platform 2 can be adjusted.
