[0027] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0028] This application discloses a motor rotor pressing tool.

[0029] Reference Figure 1 , Figure 2 and Figure 3 A motor rotor pressing fixture includes a worktable 1, an L-shaped rod 2, a cylinder 3, a pressing sleeve 4, a positioning sleeve 5, and a fixing component 6.

[0030] The workbench 1 is placed horizontally, and table legs 11 are vertically fixed at the four corners of the bottom edge of the workbench 1 to support the workbench 1. L-shaped rod 2 is fixedly installed at the top of the workbench 1, with the horizontal end of the L-shaped rod 2 located at the top of the vertical end. Cylinder 3 is vertically fixedly installed at the bottom of the horizontal end of the L-shaped rod 2. Pressing sleeve 4 is fixedly installed at the output end of cylinder 3. Positioning sleeve 5 is vertically fixedly installed at the top of the workbench 1, and positioning sleeve 5 and pressing sleeve 4 are located on the same vertical axis. Two sets of fixing components 6 are provided, and fixing components 6 are installed at the top of the workbench 1, with the two fixing components 6 located on opposite sides of positioning sleeve 5.

[0031] The operator places the motor shaft (not shown) into the positioning sleeve 5 and installs a spline (not shown) on the motor shaft. Then, the rotor laminations (not shown) are placed coaxially onto the motor shaft one by one. Two fixing components 6 are then used to secure the spline, and the cylinder 3 drives the pressing sleeve 4 downwards to press the rotor laminations, ensuring that adjacent rotor laminations are tightly abutted. The fixing components 6 prevent the spline from shaking during the rotor lamination pressing process, thus preventing improper pressing of the rotor laminations.

[0032] Each set of fixing components 6 includes a support rod 61, an automatic telescopic shaft 62, a connecting block 63, and an arc-shaped plate 64. The support rod 61 is vertically fixed to the top of the worktable 1. The automatic telescopic shaft 62 is horizontally installed at the end of the support rod 61 facing the positioning sleeve 5. The connecting block 63 is fixedly installed at the output end of the automatic telescopic shaft 62. The arc-shaped plate 64 is detachably connected to the connecting block 63 via a limiting component 7, facilitating the replacement of arc-shaped plates 64 of different sizes. It should be noted that the height of the arc-shaped plate 64 is higher than the height of the positioning sleeve 5, enabling the arc-shaped plate 64 to fix the spline. The two arc-shaped plates 64 form a circular shape, allowing the arc-shaped plate 64 to tightly abut against the spline, further enhancing the stability of the spline.

[0033] Each connecting block 63 has two horizontally formed sliding grooves 631 at the end opposite to the automatic telescopic shaft 62. The top of the connecting block 63 has two vertically formed receiving grooves 632. One receiving groove 632 and one sliding groove 631 are connected by a connecting hole 634. The connecting hole 634 is vertically formed at the bottom of the receiving groove 632. Two limiting blocks 641 are fixedly installed at the end of the arc plate 64 near the connecting block 63. The top of the limiting block 641 has a slot 642. The limiting block 641 is slidably installed in the corresponding sliding groove 631.

[0034] The limiting assembly 7 includes a limiting spring 71, a limiting rod 72, and a limiting plate 73. The limiting plate 73 is located at the opening of the receiving groove 632. A handle 731 is fixedly installed on the top of the limiting plate 73. One end of the limiting rod 72 is fixedly connected to the limiting plate 73, and the other end passes through the connecting hole 634 and is inserted into the slot 642. The limiting spring 71 is looped around the limiting rod 72. One end of the limiting spring 71 is fixedly connected to the bottom of the receiving groove 632, and the other end is fixedly connected to the limiting plate 73.

[0035] When the curved plate 64 needs to be replaced, the operator pulls the handle 731 upwards. The handle 731, through the limiting plate 73, moves the limiting rod 72 upwards, causing the limiting rod 72 to slide out of the slot 642. At this time, the limiting spring 71 is in a stretched state. Then, the operator moves the limiting block 641, causing the limiting block 641 to slide out of the slide groove 631. Then, the operator slides the limiting blocks 641 of different sized curved plates 64 into the slide groove 631 and releases the handle 731. The return spring returns to its original position, causing the limiting rod 72 to be inserted into the slot 642. It should be noted that there are two slide grooves 631, allowing two limiting blocks 641 to slide and install in the two slide grooves 631, which can enhance the stability of the connecting block 63 and the curved plate 64.

[0036] It is known that the end of the limiting rod 72 located in the slot 642 is sloping outwards towards the slide groove 631. This way, when changing the arc plate 64 of different sizes, the operator does not need to keep pulling the handle 731 upwards. After the operator removes the arc plate 64, they release the handle 731, causing the return spring to return to its original position. Then, the bottom end of the limiting rod 72 slides out of the connection hole 634 and into the slide groove 631. Subsequently, the operator slides the limiting block 641 of the arc plate 64 of different sizes into the slide groove 631. The limiting block 641 will apply an upward force to the sloping end of the limiting rod 72, causing the limiting rod 72 to slide upwards into the connection hole 634. The limiting block 641 continues to slide towards the inside of the slide groove 631. When the slot 642 on the limiting block 641 corresponds to the connection hole 634, the limiting rod 72 slides into the slot 642 under the action of the limiting spring 71, achieving the effect of saving effort. It is important to know that replacing the curved plate 64 with different sizes is to fix the splines of different sizes.

[0037] The implementation principle of the motor rotor pressing fixture in this application embodiment is as follows: The operator places the motor shaft (not shown) into the positioning sleeve 5 and installs the spline (not shown) on the motor shaft. Then, the two cylinders 3 start working, driving the arc plate 64 to move towards each other until the two arc plates 64 fix the spline. Then, the rotor laminations (not shown) are placed coaxially on the motor shaft one by one. Finally, the cylinders 3 drive the pressing sleeve 4 to press the multiple rotor laminations. By fixing the spline with the two arc plates 64, the motor shaft is fixed, which can improve the stability of the rotor laminations during the pressing process.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
