Description

Technical Field

[0001] This utility model relates to the field of motor assembly technology, and more specifically, to an auxiliary tooling for horizontal installation of motor rotors. Background Technology

[0002] Traditional motor rotor installation involves hoisting the rotor without a fixed position using slings. This makes it difficult to balance the rotor, requiring multiple workers to manually press it down at the rotor end with a pressure bar to level it before installing it into the motor stator. However, the rotor's level cannot be maintained stably during installation, causing friction between the rotor and the stator and resulting in damage to parts. Therefore, there is an urgent need to provide an auxiliary tooling for horizontal motor rotor installation to solve these problems. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an auxiliary tooling for horizontal installation of motor rotors, which solves the problem that the rotor cannot remain horizontally stable during the installation process, causing friction between the rotor and the stator and resulting in damage to the parts.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A horizontal mounting auxiliary fixture for an electric motor rotor includes a lifting frame. The rotor assembly is fitted with the lifting frame via a shaft hole. A lifting ring is installed at the top of the lifting frame, and a counterweight is mounted on the lifting frame. Limiting structures are provided at both ends of the counterweight. By changing the position of the lifting ring or increasing or decreasing the number of counterweights, the rotor can be kept horizontal.

[0006] As a further improvement to this utility model, the lifting frame includes a lifting beam and a lifting sleeve, and the lifting sleeve is connected to the lifting beam by a connecting beam.

[0007] As a further improvement to this utility model, a reinforcing beam is welded between the connecting beam and the lifting sleeve.

[0008] As a further improvement to this utility model, the limiting structure includes a positioning retaining ring welded to the lifting sleeve and a locking bolt passing through the lifting sleeve.

[0009] As a further improvement to this utility model, one side of the counterweight abuts against the positioning retaining ring, and the other side of the counterweight is abutted against by the retaining sleeve. After the locking bolt is installed, one side of the retaining sleeve is fixed.

[0010] As a further improvement to this utility model, the lifting beam is provided with several lifting points.

[0011] The beneficial technical effects of this utility model are:

[0012] The rotor can be lifted using a lifting frame, eliminating the need for manual assistance and reducing assembly difficulty. Furthermore, the rotor's balance can be adjusted by moving the lifting points, making it suitable for lifting rotors of different sizes. The use of counterweights further refines the rotor's balance, ensuring the required horizontal precision during installation. This invention offers advantages such as simple operation, high efficiency, good balance, and high installation quality. Attached Figure Description

Detailed Implementation

[0018] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0019] Combination Figure 1 - Figure 4 The present invention provides the following embodiments:

[0020] A horizontal mounting auxiliary tooling for motor rotor includes a lifting frame. The rotor assembly 100 is fitted with the lifting frame 1 via a shaft hole. A lifting ring 2 is installed at the top of the lifting frame 1. A counterweight 4 is mounted on the lifting frame 1. Limiting structures are provided at both ends of the counterweight 4. By changing the position of the lifting ring 2 or increasing or decreasing the number of counterweights 4, the rotor 100 can be kept in a horizontal state.

[0021] After the rotor assembly 100 is engaged with the shaft hole of the lifting frame 1, the lifting frame 1 is lifted by a lifting device. After lifting, the rotor assembly 100 should be kept horizontal. In order to meet the needs of rotors of different specifications, this embodiment provides adjustment of the lifting position and adjustment of the position of the counterweight to achieve balance adjustment.

[0022] In another preferred embodiment of this utility model, the lifting frame 1 includes a lifting beam 11 and a lifting sleeve 12, which are connected to the lifting beam 11 via a connecting beam 13. Specifically, referring to the accompanying drawings, the lifting beam 11 is located above, and the lifting sleeve 12 is located below, with the two parallel to each other. Both ends of the connecting beam 13 are welded to the lifting beam 11 and the lifting sleeve 12, respectively.

[0023] As another preferred embodiment of this utility model, a reinforcing beam 14 is welded between the connecting beam 13 and the lifting sleeve 12. Specifically, the strength of the lifting frame 1 is increased by the reinforcing beam 14.

[0024] As another preferred embodiment of this utility model, the limiting structure includes a positioning retaining ring 5 welded to the lifting sleeve 12 and a locking bolt 7 passing through the lifting sleeve 12. The lifting sleeve 2 has a through hole for the locking bolt 7 to pass through, and the positioning retaining ring 5 is welded to the outer wall of the lifting sleeve.

[0025] In another preferred embodiment of this utility model, one side of the counterweight 4 abuts against the positioning retaining ring 5, and the other side of the counterweight 4 is abutted against by the retaining sleeve 6. After installing the locking bolt 7, one side of the retaining sleeve 6 is fixed. Figure 1 After adding the counterweight 4, one side of the counterweight 4 abuts against the positioning retaining ring 5, and the other side of the counterweight 4 is abutted by the retaining sleeve 6. The retaining sleeve 6 is then fixed by the locking bolt 7, thereby fixing the counterweight 4.

[0026] As another preferred embodiment of this utility model, the lifting beam 11 is provided with a plurality of lifting points 3. Specifically, referring to the accompanying drawings, in this embodiment, the lifting beam 11 is provided with three lifting points 3 for adjusting the position of the lifting ring 2. In this embodiment, the lifting ring 2 is threadedly connected to the lifting points 3.

[0027] When the rotor assembly 100 and stator assembly 200 are horizontally assembled, the inner hole of the lifting sleeve 12 of the lifting frame 1 matches the outer diameter of the shaft of the rotor assembly 100. Then, the lifting ring 2 is placed at the lifting point 3. The lifting equipment is used to test lift first. If it is balanced, it can be directly horizontally assembled. If it is not balanced, the lifting point 3 can be changed first, the balance can be adjusted and tested again. If it is still not balanced, the weight 4 is installed, and the rear end of the lifting sleeve 12 is fitted with a retaining sleeve 6 for positioning. It is fixed with locking bolts 7 and nuts to achieve the balance of lifting the rotor assembly 100.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
