[0016] Compared with the prior art, the water pump assembly device of the present invention has the following beneficial effects: 1. The core shaft and the impeller are positioned by embedding the lifting and positioning mechanism into the first keyway and the positioning mechanism into the second keyway to determine the relative position of the core shaft and the impeller, so that when the impeller is sleeved on the outside of the core shaft, the first keyway can be opposite to the second keyway, and the connecting key can be simultaneously embedded in the first keyway and the second keyway to improve the assembly accuracy of the core shaft and the impeller. When the impeller is sleeved on the outside of the core shaft, there is no need to rotate the impeller to adjust the position of the second keyway, thereby improving the assembly efficiency and accuracy of the product, and avoiding interference between the connecting key and the impeller to improve the quality of the product.

[0017] 2. By setting a first threaded hole in the translation plate and passing the first lead screw through the first threaded hole, the first lead screw is threadedly connected to the translation plate, so as to rotate the first lead screw, so that the first lead screw drives the translation plate to move, and then adjusts the position of the translation plate; by fixing the first motor on the workbench and connecting the first output shaft of the first motor to the first lead screw, the first motor can drive the first lead screw to rotate, thereby providing power for rotating the first lead screw.

[0018] 3. When the core shaft is not embedded between the two first clamping blocks, start the first cylinder, so that the first cylinder drives the adjusting block to move in the direction away from the core shaft, so that the adjusting block presses the two first clamping blocks to move to both sides, and then the first clamping block drives the first limit plate to move outward through the first connecting rod, and the first spring is in a stretched state at this time; when the core shaft is embedded between the two first clamping blocks, and the core shaft is simultaneously fitted with the two first clamping blocks, start the first cylinder, so that the first cylinder drives the adjusting block to move in the direction of the core shaft, and the first spring is reset and drives the first connecting rod to move inward, so that the core shaft is embedded in the two first clamping grooves at the same time, and then the elastic force of the first spring is used to clamp the core shaft with the two first clamping blocks; then, rotate the first slewing bearing, so that the first slewing bearing drives the first mounting frame and the core shaft to rotate, thereby adjusting the direction of the first keyway, and then ensuring that the first keyway is facing upward, so that the subsequent impeller can be mounted on the outside of the core shaft.

[0019] 4. By setting the first mounting groove in the translation plate and installing the second motor in the first mounting groove, the second motor can be hidden in the translation plate, and the translation plate can also support the second motor; by setting the first external tooth on the outer wall of the first slewing bearing, the first gear is mounted on the outer side of the second output shaft of the second motor, and the first gear is meshed with the first external tooth, so that the second motor can drive the first gear to rotate, thereby realizing that the first gear meshes with the first external tooth and drives the first slewing bearing to rotate, thereby providing power for the rotating spindle.

[0020] 5. After the first clamping and rotating mechanism clamps the mandrel, the second cylinder is started, so that the second cylinder drives the first lifting plate and the first positioning plate to move upward, and makes the first positioning plate fit with the outer wall of the mandrel (the first positioning plate is not embedded in the first keyway), and the second spring is compressed at this time; then, the first clamping and rotating mechanism is started, so that the first clamping and rotating mechanism drives the mandrel to rotate, and when the first keyway is opposite to the first positioning plate, the second spring is reset and drives the first positioning plate to embed into the first keyway, so that the mandrel stops rotating, and the first clamping and rotating mechanism stops at this time; then, the second cylinder is started, so that the second cylinder drives the first lifting plate and the first positioning plate to move downward, so that the first positioning plate is disengaged from the first keyway, and drives the first lifting plate and the first positioning plate to embed into the first accommodating groove, so as to avoid the subsequent interference of the first positioning plate with other components; then, the first clamping and rotating mechanism is started, so that the first clamping and rotating mechanism drives the mandrel to rotate 90 degrees, so that the first keyway faces upward, so that the staff can place the connecting key in the first keyway.

[0021] 6. By installing the fourth cylinder on the second lifting plate and connecting the press plate with the fourth driving shaft of the fourth cylinder, the second lifting plate and the fourth cylinder can be moved up and down synchronously, so that the fourth cylinder can drive the press plate to move, and then the press plate can press the impeller on the outside of the core shaft; by setting the clearance groove in the press plate and making the clearance groove opposite to the core shaft to avoid interference between the core shaft and the press plate, it is ensured that the press plate can press the impeller to the outside of the core shaft, so as to improve the product experience.

[0022] 7. When the impeller is placed on the rotating plate from top to bottom, the impeller presses multiple second clamping blocks to move outward through chamfering. At this time, the second clamping blocks compress the third spring, so that the impeller is clamped by the elastic force of the third spring to ensure that the rotating plate and the impeller rotate synchronously; then, start the third motor to drive the second gear to rotate, thereby driving the rotating plate and the impeller to rotate to adjust the position of the second keyway.

[0023] 8. When the impeller is placed on the rotating plate, the second positioning plate fits against the inner wall of the impeller (the second positioning plate is not embedded in the second key slot). At this time, the impeller presses the second positioning plate to move toward the center line of the impeller, thereby compressing the fourth spring; then, the rotating plate and the impeller are rotated; when the second positioning plate is opposite to the second key slot, the fourth spring is reset and drives the second positioning plate to move, thereby embedding the second positioning plate in the second key slot to achieve positioning of the second key slot.

[0024] 9. The second threaded hole is set in the translation stage, and the second screw passes through the second threaded hole to achieve threaded connection between the second screw and the translation stage, so as to rotate the second screw and drive the translation stage to move. The buffer seat is connected to a second support plate, so that the buffer seat is located above the core shaft, and the buffer seat is opposite to the translation stage, so that a second support plate supports the buffer seat, so that when the translation stage moves to the second support plate, the translation stage contacts the buffer seat, thereby positioning the translation stage.

[0025] 10. The third lifting plate is located in the lifting frame, and the third lead screw passes through the third threaded hole of the third lifting plate to achieve threaded connection between the third lead screw and the third lifting plate, so as to rotate the third lead screw, so that the third lead screw drives the third lifting plate to move up and down in the lifting frame; one end of the two fifth connecting rods is connected to the third lifting plate, the other ends of the two fifth connecting rods pass through the lifting frame, and the other ends of the two fifth connecting rods are connected to the clamping and flipping mechanism, so that when the third lifting plate moves up and down, the third lifting plate drives the clamping and flipping mechanism to move up and down through the two fifth connecting rods, so as to adjust the height of the clamping and flipping mechanism. The fifth motor is installed on the translation stage, and the first pulley is mounted on the outside of the fifth output shaft of the fifth motor, so that the translation stage supports the fifth motor, so that the fifth motor can drive the first pulley to rotate; the second pulley is mounted on the outside of the rotating shaft, and the belt is mounted on the outside of the first pulley and the second pulley at the same time, so that when the fifth motor drives the first pulley to rotate, the first pulley drives the rotating shaft to rotate through the second pulley and the belt, so as to provide power for rotating the rotating shaft.

[0026] 11. When the second mounting frame moves to the top of the impeller and the first inner support block and the second inner support block are embedded in the impeller, the sixth motor is started to make the sixth motor drive the fourth lead screw to rotate, so that the fourth lead screw drives the first inner support block and the second inner support block to move in opposite directions, so that the first inner support block and the second inner support block are simultaneously fitted with the inner wall of the impeller; then, the fifth motor is started to make the fifth motor drive the third lead screw to rotate, so that the third lead screw drives the third lifting plate and the two fifth connecting rods to move upward, so as to drive the second mounting frame and the impeller to move upward; when the impeller moves upward to a predetermined height, the fifth cylinder is started to make the fifth cylinder drive the third mounting frame to rotate 90 degrees, so that the impeller is flipped 90 degrees, at this time the second keyway in the impeller is aligned with the keyway placed in the first keyway The connecting key is relative to each other; then, the fourth motor is started to drive the second lead screw to rotate, so that the second lead screw drives the translation table and the impeller to move in the direction of the core shaft, and then the impeller is sleeved on the outside of the core shaft; when at least two-thirds of the impeller is sleeved on the outside of the core shaft (at this time the core shaft can support the impeller), the sixth motor is started to drive the fourth lead screw to rotate, so that the fourth lead screw drives the first inner support block and the second inner support block to move relative to each other, and then the first inner support block and the second inner support block are separated from the inner wall of the impeller; then, the fourth motor is started to drive the second lead screw to rotate in the opposite direction, so that the second lead screw drives the translation table and the impeller to move away from the core shaft, and then the first inner support block and the second inner support block are moved out of the impeller.
