Description

Technical Field

[0001] The utility model relates to the field of motor processing equipment, and more specifically, to a motor rotor turning device. Background Art

[0002] During the motor rotor machining process, a turning device is required to flip the motor rotor. For example, the utility model with authorization publication number CN 219666341U discloses a motor rotor turning assist device, and the utility model with authorization publication number CN 215452730U discloses a turning device for generator rotor machining. The technical solutions disclosed in these patents both utilize two relatively sliding brackets with clamping mechanisms disposed on the brackets, securing the two ends of the rotor shaft via the two clamping mechanisms. However, when achieving the connection between the clamping mechanisms and the rotor shaft, ensuring the stability of the motor rotor presents a challenge. Using a hoisting system, contact between the clamping mechanism and the rotor shaft can easily cause the rotor to shift slightly, making alignment difficult. Using a support device also requires an additional support frame. Furthermore, the rotor core sizes of motor rotors of different specifications vary, and the height of the support frame is difficult to determine. Therefore, there is a need for a motor rotor turning device that can ensure stability during the motor rotor connection and positioning process. Utility Model Content

[0003] The purpose of the utility model is to provide a motor rotor turning device, which can ensure the stability of the motor rotor during the connection and positioning process with the clamping mechanism.

[0004] The utility model solves the above technical problems with the following technical solutions: a motor rotor turning device, comprising:

[0006] Two sets of rotor clamping mechanisms, which are rotatably arranged on the fixed bracket and the movable bracket respectively;

[0007] A rotation drive mechanism, which is provided on the fixed bracket and is transmission-connected to the corresponding rotor clamping mechanism;

[0008] The rotor supporting mechanism is arranged on the first linear driving mechanism through a lifting mechanism.

One end of the first screw rod is transmission-connected to the first driving unit, and the other end of the first screw rod is rotationally connected to the inner wall of the first sliding groove.

[0014] Furthermore, in the motor rotor turning device, the rotor clamping mechanism includes:

[0019] Furthermore, in the motor rotor turning device, the rotor support mechanism includes:

[0025] The beneficial effects of the utility model are:

[0026] In the motor rotor turning device of the present invention, the rotor clamping mechanism on the movable bracket can approach or move away from the rotor clamping mechanism on the fixed bracket. At the same time, a rotor supporting mechanism is arranged between the two sets of rotor clamping mechanisms, and the rotor supporting mechanism is driven to move horizontally and up and down respectively by the first linear drive mechanism and the lifting mechanism. The rotor core of the motor rotor is supported by the rotor supporting mechanism, thereby ensuring that the motor rotor remains stable during the connection process between the rotor shaft and the rotor clamping mechanism, thereby facilitating the connection of the rotor shaft and the rotor clamping mechanism.

[0033] Figure 1-Figure 3 The present invention provides a motor rotor turning device, comprising:

[0034] A base 1 is provided with a fixed bracket 2, a first linear drive mechanism 3 and a second linear drive mechanism 4 in sequence, and a movable bracket 5 is provided on the upper end of the second linear drive mechanism 4;

[0035] Two sets of rotor clamping mechanisms 6, which are rotatably disposed on the fixed bracket 2 and the movable bracket 5 respectively;

[0036] A rotation drive mechanism 7, which is provided on the fixed bracket 2 and is in transmission connection with the corresponding rotor clamping mechanism 6;

[0037] The rotor supporting mechanism 8 is arranged on the first linear driving mechanism 3 through a lifting mechanism 9 .

[0038] In this embodiment, in the initial state, the second linear drive mechanism 4 drives the mobile support 5 away from the fixed support 2, and the height of the rotor support mechanism 8 is pre-adjusted by the lifting mechanism 9 so that the motor rotor is placed on the rotor support mechanism 8. At this time, the motor rotor and the two sets of rotor clamping mechanisms 6 are located on the same straight line. Then, the first linear drive mechanism 3 drives the rotor support mechanism 8 toward the fixed support 2, and the rotor shaft of the motor rotor is connected to the rotor clamping mechanism 6 on the fixed support 2. The second linear drive mechanism 4 then drives the mobile support 5 toward the fixed support 2, completing the connection between the rotor shaft of the motor rotor and the rotor clamping mechanism 6 on the mobile support 5, thereby completing the connection between the two sets of rotor clamping mechanisms 6 and the rotor shaft. Then, the lifting mechanism 9 drives the rotor support mechanism 8 downward to the bottom of the motor rotor, and the rotation drive mechanism 7 drives the corresponding rotor clamping mechanism 6 to rotate, realizing the flipping of the motor rotor.

[0048] A plurality of positioning bolts 62 are threadedly installed in each of the threaded through holes.

[0049] In this embodiment, the inner diameter of the positioning slot is the same as the outer diameter of the rotor shaft end. The rotor shaft end is inserted into the positioning slot, and then the positioning bolt 62 is tightened to secure the rotor shaft end.

[0057] At least one hydraulic cylinder 92, which is provided on the first linear drive mechanism 3, and whose telescopic rod is upwardly arranged and connected to the lifting plate 91;

[0058] A plurality of limiting rods 93 are vertically arranged on the first linear drive mechanism 3 . The limiting rods 93 pass through the lifting plate 91 and are slidably connected thereto.

[0059] In this embodiment, the lifting plate 91 is moved up and down by the extension and retraction of the telescopic rod of the hydraulic cylinder 92, and the lifting plate 91 is limited by a plurality of limiting rods 93 to ensure its stability during the lifting process.
