Description

Technical Field

[0001] The utility model relates to the technical field of rotor installation tools, and particularly relates to a special installation tool for a large motor rotor. Background Art

[0002] A motor refers to an electromagnetic device that realizes the conversion of electricity (electrical energy to kinetic energy) based on the law of electromagnetic induction. Since it can generate a stable driving torque, it is widely used in various machining fields.

[0003] Currently, during the assembly of a large permanent magnet composite motor, the outer circle of the first rotor is magnetic. An adjusting magnetic ring can be assembled around it to form an inner rotor. The inner rotor needs to be assembled with a stator with the inner surface of the magnetic steel installed. Due to the special structure and installation accuracy requirements, there should be no rubbing between the adjusting magnetic ring and the first rotor, and the inner rotor should not collide with the stator. When using a crane hook to hoist and pass the rotor, it is impossible to accurately align, which may cause impacts on the motor shaft, inner rotor, and the inner surface of the stator, resulting in damage, destroying the internal structure of the motor, and affecting the overall quality of the motor.

[0004] Therefore, how to design a special tool for a large motor rotor with accurate positioning, convenient installation, and not easy to bump is an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0005] The utility model provides a special installation tool for a large motor rotor, which solves the technical problem of difficult installation and easy bumping of the existing rotor.

[0006] The technical solution of the utility model to solve the above technical problems is as follows. A special installation tool for a large motor rotor is installed on a horizontal lathe. The horizontal lathe includes a horizontal lathe guide rail, a horizontal lathe tool rest, and a horizontal lathe sealing plate. The horizontal lathe tool rest slides on the horizontal lathe guide rail. The horizontal lathe sealing plate is fixed at one end of the horizontal lathe guide rail far from the motor housing and has a positioning hole in the middle. It includes a positioning center pin and a support plate.

[0007] The shank end of the positioning center pin is coaxially and detachably inserted into the positioning hole, and its tip can be coaxially sleeved with the output shaft of the motor. The support plate is parallel to and located below the positioning center pin and is fixed on the horizontal lathe tool rest.

[0008] The beneficial effect of the utility model is as follows: First, the rotor to be installed is sleeved on the outer peripheral side of the positioning center pin, and then the rotor is supported by the support plate. When the rotor needs to be installed, the horizontal lathe tool rest is pushed. Since the positioning center pin is coaxially sleeved with the output shaft of the motor, the rotor can be positioned and installed, avoiding the rotor from bumping against the housing, stator, or output shaft, and improving the convenience and safety of rotor installation.

[0009] On the basis of the above technical solution, the present utility model can be further improved as follows.

[0010] Further, it further includes a height adjustment assembly. The height adjustment assembly includes a height adjustment plate and a plurality of adjustment bolts. A plurality of connection holes are provided on the support plate; the height adjustment plate is parallel and located above the support plate, and a plurality of threaded holes respectively arranged opposite to the plurality of connection holes are provided thereon; the plurality of adjustment bolts are respectively screwed into the plurality of threaded holes, and their screwed ends are rotatably connected in the corresponding connection holes.

[0011] The beneficial effect of the above further improvement is that by rotating the plurality of adjustment bolts to change the horizontal height of the plurality of height adjustment plates, it is convenient to place the rotor to be installed and can also adapt to rotors of different sizes, improving the convenience and adaptability of the disassembly and assembly of the special tool.

[0012] Further, it further includes a sliding seat. There are two horizontal lathe guide rails arranged in parallel at intervals; the horizontal lathe tool post slides on one of the horizontal lathe guide rails; the sliding seat slides on the other horizontal lathe guide rail, and its top end is fixed to the bottom surface of the support plate through a cross beam.

[0013] The beneficial effect of the above further improvement is that first, the horizontal lathe tool post slides on one of the horizontal lathe guide rails, and then the sliding seat slides on the other horizontal lathe guide rail. Since the bottom surface of the support plate is fixed to the horizontal lathe tool post and the cross beam, the sliding stability of the support plate can be improved.

[0014] Further, the horizontal lathe further includes a clamping assembly. The clamping assembly includes a plurality of jaws. The plurality of jaws are fixed to the horizontal lathe closing plate in a scattered manner with the positioning hole as the origin, and their clamping ends reciprocate in the direction from near the positioning hole to far from the positioning hole to clamp or release the positioning thimble.

[0015] The beneficial effect of the above further improvement is that by using the clamping ends of the plurality of jaws to clamp the positioning thimble, the stability of the positioning thimble can be improved. Description of the Drawings
