DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] Example: Figure 1-3 As shown, a motor assembly pressing device comprises a workbench 1, a pressure platform 2 is arranged at the middle part of the top of the workbench 1, a support frame 3 is rotatably connected to the right side of the top of the workbench 1, a connecting block 4 is fixedly connected to the top of the support frame 3, a plurality of fixing rods 5 are slidably connected to the outside of the connecting block 4, a clamping assembly is fixedly connected to the outer end of the fixing rod 5, a fixing frame 6 is fixedly connected to the top of the workbench 1, a column 7 is slidably connected to the inside of the fixing frame 6, a top supporting block 8 is fixedly connected to the top of the column 7, and the top supporting block 8 cooperates with the fixing rod 5, a driving assembly is arranged on the right side of the column 7, and the bottom end of the column 7 abuts against the upper end surface of the workbench 1, so that the combination of the column 7 and the top supporting block 8 can support the fixing rod 5, and the load at the connection between the fixing rod 5 and the connecting block 4 is reduced;

[0022] The rotating shaft assembly is clamped by the clamping assembly, and the support frame 3 rotates to drive the connecting block 4 to rotate, so that the fixed rod 5, the clamping assembly and the rotating shaft assembly rotate, and then the rotating shaft assembly is suspended above the pressure platform 2. When the motor pressing is completed, the rotating shaft assembly moves down along the clamping assembly and sinks into the pressure platform 2. At this time, the driving assembly works to drive the column 7 to move upward along the fixed frame 6, and then the top support block 8 is raised, so that the fixed rod 5 moves upward along the connecting block 4, so that the rotating shaft assembly is separated from the pressure platform 2, no manual operation is required, and it is more convenient to use.

[0023] Specifically, Figure 2 As shown, the driving assembly includes a motor 11, and the motor 11 is fixedly connected to the top of the workbench 1, the output end of the motor 11 is fixedly connected to a gear 10, the outer side of the gear 10 is meshed with a rack 9, and the rack 9 is fixedly connected to the right side of the column 7. The motor 11 drives the gear 10 to rotate, and the rotating gear 10 acts on the rack 9, thereby driving the column 7 to move upward along the fixed frame 6.

[0024] Specifically, Figure 3As shown, the clamping assembly includes a pair of arc-shaped spring pieces 13, which are fixedly connected to the outer ends of the fixed rod 5, and the outer ends of the pair of arc-shaped spring pieces 13 are fixedly connected with clamping blocks 14. The pair of arc-shaped spring pieces 13 are symmetrically arranged and extended outward. The outer sides of the pair of arc-shaped spring pieces 13 are sleeved with positioning rings 15, and the left and right sides of the positioning rings 15 are fixedly connected with protrusions 17. One side of the protrusion 17 is fixedly connected with a telescopic electric cylinder 16, and the telescopic electric cylinder 16 is fixedly connected to the outer side of the fixed rod 5. The telescopic electric cylinder 16 works on the protrusion 17, thereby moving the positioning ring 15 along the arc-shaped spring piece 13. As the positioning ring 15 moves, the arc-shaped spring piece 13 is restrained, so that the two clamping blocks 14 move toward each other, and the rotating shaft assembly is clamped, which is more convenient to use.

[0025] Specifically, Figure 1 As shown, chamfers are provided on both the front and rear sides of the upper end face of the top support block 8, and counterweight blocks 12 are fixedly connected to the front and rear sides of the bottom end of the top support block 8. The chamfers are provided to reduce the height of the front and rear ends of the top support block 8, so that the fixing rod 5 can move more smoothly to the top of the top support block 8. The counterweight block 12 is provided at the bottom end of the top support block 8 to increase the weight of the top support block 8. After the fixing rod 5 is moved out of the top support block 8, the motor 11 stops working, and the gear 10 reverses under the action of the top support block 8, the rack 9 and the counterweight block 12, so that the top support block 8 can reset itself.

[0026] Working principle: The rotating shaft assembly is placed between the two clamping blocks 14, and the telescopic electric cylinder 16 works on the protrusion 17, so that the positioning ring 15 moves along the arc-shaped spring piece 13. As the positioning ring 15 moves, the arc-shaped spring piece 13 is bound, so that the two clamping blocks 14 move toward each other to clamp the rotating shaft assembly. The support frame 3 rotates to drive the connecting block 4 to rotate, so that the fixing rod 5, the clamping assembly and the rotating shaft assembly rotate, and then the rotating shaft assembly is suspended above the pressure platform 2. When the motor is pressed, the rotating shaft assembly moves down along the clamping assembly. It is not immersed in the pressure platform 2, and the motor 11 drives the gear 10 to rotate. The rotating gear 10 acts on the rack 9, which drives the column 7 to move upward along the fixed frame 6, thereby raising the top support block 8, so that the fixed rod 5 moves upward along the connecting block 4, separates the rotating shaft assembly from the pressure platform 2, and then the support frame 3 rotates to take away the pressed motor. After the fixed rod 5 moves out of the top support block 8, the motor 11 stops working, and the gear 10 reverses under the action of the top support block 8, the rack 9 and the counterweight block 12, so that the top support block 8 can reset itself.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
