[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0018] As shown in Figures 1 and 2, this top-lifting impeller press includes a pressing device 1 and a mounting plate 2 for fixing the motor assembly. The pressing device 1 includes a lifting device 3, a lifting support device 4, and a pressing device 5. The lifting device 3 is used to lift the mounting plate 2 close to the pressing device 5. The lifting support device 4 can rise or fall and is used to support the spindle of the motor assembly. The pressing device 5 is used to press the impeller on the motor assembly down to the designated position.
[0019] To elaborate further, the molding device 1 also includes a base plate 21 for mounting the lifting device 3. The lifting device 3 includes a first cylinder 6 and a lifting plate 7. The first cylinder 6 is used to drive the lifting plate 7 to rise or fall. The lifting plate 7 is used for mounting the lifting support device 4 and for supporting the mounting plate 2.
[0020] This setting is used to ensure that the lifting device 3 does not affect the lifting support device 4. While the first cylinder 6 raises the lifting plate 7, it also drives the lifting support device 4 to rise.
[0021] To elaborate further, the bottom surface of the lifting plate 7 is provided with multiple first guide rods 8, and the bottom plate 21 is provided with first through holes 9 for the first guide rods 8 to pass through.
[0022] This setting is used to increase the stability of the lifting plate 7 during lifting, which can ensure the accuracy of the process.
[0023] To elaborate further, the top surface of the lifting plate 7 is provided with a support block 10, which is used to support the mounting plate 2. The lifting support device 4 adopts a pneumatic support cylinder, and the mounting plate 2 is provided with a second through hole 11 for the pneumatic support rod to pass through.
[0024] A support block 10 is provided to ensure that there is space between the lifting plate 7 and the mounting plate 2 for the installation of the pneumatic support rod. The piston rod of the pneumatic support cylinder passes through the second through hole 11 and abuts against the spindle of the motor assembly to support the spindle and prevent the spindle from shifting when the pressing device 5 presses down, which would cause a decrease in overall accuracy.
[0025] To elaborate further, the molding device 1 also includes a top plate 12 for mounting the pressing device 5. The pressing device 5 includes a second cylinder 13 and a pressing connector 14. The second cylinder 13 is used to drive the pressing connector 14 to rise or fall. The pressing connector 14 includes a connector 15, a pressing block 16 and an abutment block 17, which are integrally formed.
[0026] The connector 15 is detachably connected to the second cylinder 13. The abutment block 17 is used to press down and abut against the top surface of the motor assembly bracket, while the pressing block 16 is used to push the impeller down. By adjusting the height of the abutment block 17, the position of the impeller after installation can be adjusted. When the abutment block 17 wears out after long-term use, it can be replaced to ensure installation accuracy.
[0027] To elaborate further, the second cylinder 13 is provided with a second guide rod 18, and a third through hole 20 is provided on the bottom of the outer casing of the second cylinder 13 for the second guide rod 18 to pass through.
[0028] This setting is used to increase the stability of the lower pressure connector 14 during lifting and lowering, which can ensure the accuracy of the process.
[0029] In more detail, it also includes a double-speed chain and a blocking device 19. The double-speed chain is used to transport the mounting plate 2, and the blocking device 19 is used to prevent the mounting plate 2 from leaving the molding device 1. The blocking device 19 is set on the base plate 21 and adopts a blocking cylinder.
[0030] Both the double-speed chain and the blocking device 19 adopt existing technologies. The mounting plate 2 is a conveyor plate set on the double-speed chain, and a base for fixing the motor assembly is also installed. The mounting plate 2 is conveyed by the double-speed chain, which acts as a conveyor line. At the same time, in conjunction with the blocking device 19, the mounting plate 2 stops moving forward after reaching the designated position, which limits the position of the mounting plate 2 and ensures the subsequent installation accuracy. The lateral distance between the blocking device 19 and the pressing device 5 can be adjusted.
[0031] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0032] Although this document uses a large number of technical terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
