Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] In the traditional assembly process of the main shaft and the rotor, the main shaft is generally manually inserted into the center of the rotor for connection. However, since the main shaft and the rotor need to have an interference fit, the efficiency of manual connection is low. Later, the main shaft is clamped by a machine, the rotor is placed manually, and the machine is started for connection. During the connection process, the end face of the inserted end of the main shaft is easy to touch the end face of the rotor, causing wear of the main shaft or the rotor, that is, the connection between the main shaft and the rotor cannot be completed in one go.

[0046] In order to solve the above technical problems, in at least one embodiment, an assembly tool for rotor pressing is provided, including: a guide sleeve 6; wherein a guide groove 60 is vertically opened on the inner wall of the guide sleeve 6; and an assembly mechanism, which is respectively connected to the main shaft 1 and the rotor 5; wherein the assembly mechanism is suitable for sliding along the guide groove 60 to drive the main shaft 1 and the rotor 5 to move, and then the main shaft 1 is inserted into the rotor 5.

[0047] An assembly mechanism is provided, wherein the rotor assembly component and the spindle assembly component are used to fix the rotor 5 and the spindle 1 respectively, and then the two are placed in the guide sleeve 6 and relatively moved along the guide groove 60 until the spindle 1 is inserted into the rotor 5. Due to the presence of the spindle seat 2 and the rotor seat 4, the spindle 1 can be inserted into the rotor 5 at one time without contacting the end surface of the rotor 5 to cause wear.

[0048] In some embodiments, Figure 1 As shown, the rotor 5 is placed on the upper end surface of the rotor seat 4, and the contact surfaces of the two are fixed (the fixing method of the two is the existing technology, such as bolt fixing, etc., and in order to ensure that the rotor is subsequently placed stably inside the guide sleeve 6, a counterweight block can be added to the upper and lower end surfaces of the rotor 5, and the counterweight block is connected to the rotor 5 by bolts), and the rotor mounting hole on the rotor sliding block 40 is overlapped with the rotor connecting hole 42 opened on the outer wall of the rotor seat 4, and then the rotor assembly bolt 41 is used to pass through the rotor mounting hole and threadedly connect with the rotor connecting hole 42 to fix the rotor sliding block 40 on the outer wall of the rotor seat 4.

[0049] In some embodiments, Figure 2 As shown, one end of the spindle 1 is inserted into the spindle insertion position 20 so that the spindle 1 is connected to the spindle seat 2, and then the spindle mounting hole opened on the spindle sliding block 21 is overlapped with the spindle connecting hole 22 opened on the outer wall of the spindle seat 2, and the spindle assembly bolt 23 is passed through the spindle mounting hole and threadedly connected with the spindle connecting hole 22 to fix the spindle sliding block 21 to the spindle seat 2.

[0050] In some embodiments, Figure 3As shown, the guide sleeve 6 is placed vertically, and then the rotor seat 4 and the rotor 5 are first placed in the guide sleeve 6. At this time, the rotor sliding block 40 is located in the guide groove 60 and slides, driving the rotor seat 4 to slide to the bottom of the guide sleeve 6. Then the spindle seat 2 is placed in the guide sleeve 6. At this time, the spindle sliding block 21 is located in the guide groove 60 and slides, driving the spindle seat 2 and the spindle 1 fixed to the spindle seat 2 to slide down in the guide sleeve 6 until the spindle 1 is inserted into the center of the rotor 5 so that the two are connected.

[0051] In some embodiments, Figure 3 As shown, the center of the rotor seat 4 is hollowed out to accommodate the insertion of the main shaft 1, and the outer diameters of the main shaft seat 2 and the rotor seat 4 are the same, so that when the main shaft seat 2 slides close to the rotor seat 4, the main shaft 1 is directly inserted into the center of the rotor 5 without contacting the end surface of the rotor 5 and causing wear.

[0052] In some embodiments, the method of driving the main shaft seat 2 to slide downward in the guide sleeve 6 includes but is not limited to being pushed by a cylinder.
