Description

Technical Field

[0001] This utility model relates to the technical field of motor rotor assembly equipment, and in particular to a motor rotor shaft clamping and alignment device. Background Technology

[0002] The motor rotor refers to the rotating part of the motor. The structure of the motor rotor mainly includes the rotor shaft and the iron core lamination assembly. During the assembly process, one end of the rotor shaft needs to be aligned with the center of the iron core lamination assembly, and the rotor shaft needs to be pressed into the interior of the iron core assembly to make the rotor shaft and the iron core assembly tightly pressed together. After the assembly is completed, the iron core lamination with the rotor shaft is placed on the rotor tooling, and the rotor tooling is transported to the assembly station of the subsequent process through the conveyor line to be assembled into the motor rotor.

[0003] In existing assembly processes of rotor shafts and core lamination assemblies, manual placement or riveting equipment is generally used to directly align the rotor shaft with the through holes of the core laminations and then press the rotor shaft into the core lamination assembly. However, this process cannot ensure that the rotor shaft is in the internal position of the core assembly, which can easily lead to rotor shaft misalignment, resulting in the rotor shaft being tilted inside the core lamination assembly. Furthermore, when transporting the core lamination assembly with the rotor shaft to the subsequent assembly station, the shaking during transportation can cause the rotor shaft to loosen inside the core lamination assembly, resulting in positional misalignment. Therefore, the concentricity of the rotor shaft and the core lamination assembly cannot be guaranteed, which in turn affects the assembly quality of the motor rotor.

[0004] Referring to the Chinese utility model patent with publication number "CN219372213U" and titled "Rotor Shaft Insertion Machine into Iron Core," the technical solution discloses "a rotor shaft insertion machine into an iron core, comprising a frame, a first tray for placing the rotor shaft, a second tray for placing the iron core, a first transfer mechanism for transferring the rotor shaft, a first positioning mechanism for positioning the rotor shaft, a second transfer mechanism for transferring the rotor shaft, a second positioning mechanism for positioning the iron core, a transport mechanism for transporting the rotor shaft and the iron core, and a pressing mechanism for pressing the rotor shaft into the iron core. The frame is equipped with a worktable; the machine employs the first transfer mechanism, the first positioning mechanism, the second transfer mechanism, the second positioning mechanism, and the transport mechanism..." The automated assembly and pressing mechanism realizes the transfer and positioning of the rotor shaft and the iron core, as well as the handling and pressing of the rotor shaft and the iron core. This technical solution effectively realizes the automated assembly of the rotor shaft and the iron core. Before the assembly action, the rotor shaft is positioned by the first positioning mechanism and the iron core is positioned by the second positioning mechanism to improve the pressing accuracy. However, this technical solution cannot solve the problem that the rotor shaft is prone to shaking when the iron core with the rotor shaft is transported to the subsequent station after the rotor shaft is assembled to the iron core, which causes the rotor shaft position to deviate. It cannot achieve the goal of correcting the rotor shaft when the iron core with the rotor shaft is transported to the subsequent station to ensure the positional accuracy of the rotor shaft and the iron core laminations.

[0005] Therefore, how to achieve automatic shaft alignment is the main problem that technicians need to solve. Utility Model Content

[0006] The purpose of this invention is to provide a motor rotor shaft clamping and alignment device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A motor rotor shaft clamping and alignment device, comprising:

[0009] Mounting plate, rotating motor, and two symmetrically arranged sliding plates;

[0010] The rotary motor is located directly below the mounting plate. The mounting plate has a mounting opening at its center, which is aligned with the power output end of the rotary motor and is used for the power output end of the rotary motor to extend out.

[0011] Both sliding plates are slidably mounted on the mounting plate. One end of each sliding plate is tangent to the power output end of the rotating motor. One end of each sliding plate is provided with a transmission rack, which is connected to the power output end of the rotating motor. The top of each sliding plate is provided with a correction plate. The outer side of the correction plate is provided with a correction groove for abutting the rotor shaft. The inner wall of the correction groove is adapted to the outer wall of the rotor shaft.

[0012] Preferably, the power output end of the rotary motor is fitted with a drive gear, and the transmission rack extends along the length direction of the sliding plate, and the drive gear meshes with the transmission rack.

[0013] Preferably, when the two correction plates abut each other, the two correction grooves abut each other and form a correction through hole for the rotor shaft to pass through. The inner wall of the correction through hole fits against the outer wall of the rotor shaft, and the central axis of the correction through hole and the central axis of the mounting plate are both located on the same central axis.

[0014] Preferably, the mounting plate is further provided with two push cylinders, and the two push cylinders are symmetrically arranged on both sides of the outer side of the mounting plate. The other ends of the two sliding plates are respectively connected to the power output ends of the two push cylinders.

[0015] Preferably, the two sliding plates are provided with mounting sliders on the side facing the mounting plate, and the mounting plate is provided with mounting rails on the side facing the sliding plates, and the mounting sliders are slidably connected to the mounting rails.

[0016] Preferably, the power output end of the push cylinder is connected to a fixed push block, which is fitted and connected to the other end of the sliding plate.

[0017] Preferably, the top of the mounting plate is further provided with several fixed supports, which are evenly distributed on the top of the mounting plate and are used to support the transport plate with the rotating iron core.

[0018] Compared with the prior art, this technical solution provides a motor rotor shaft clamping and straightening device: It comprises a mounting plate, a rotating motor, and two symmetrically arranged sliding plates. The rotating motor is positioned directly below the mounting plate, and an installation opening is provided at the top of the mounting plate to facilitate the extension of the motor's power output end. The two sliding plates are slidably mounted on the mounting plate, with one end of each sliding plate tangent to the power output end of the rotating motor. A transmission rack is provided at one end of each sliding plate and is connected to the rotating motor. When the rotor shaft is directly above the mounting plate, it can be clamped and straightened by rotating the mounting plate. The motor's power output drives two sliding plates to move towards each other on the mounting plate. This causes the correction grooves on the two correction plates to move toward the rotor shaft. During this movement, the rotor shaft is corrected in position until the two correction grooves completely merge. This ensures that the center axis of the rotor shaft and the center axis of the mounting plate are on the same center axis, thus achieving the alignment of the rotor shaft. This, in turn, ensures the concentricity of the rotor shaft and the core assembly after the correction action. It effectively achieves automated alignment of the rotor shaft of the core assembly with the rotor shaft, improving production efficiency and ensuring the quality of motor rotor assembly.

[0029] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0030] refer to Figures 1 to 2 A motor rotor shaft clamping and straightening device includes: a mounting plate 1, a rotating motor 2, and two symmetrically arranged sliding plates 3; the rotating motor 2 is located directly below the mounting plate 1, and a mounting opening 10 is provided at the center of the mounting plate 1, the mounting opening 10 is aligned with the power output end of the rotating motor 2, and the mounting opening 10 is used for the power output end of the rotating motor 2 to extend out.

[0031] Both sliding plates 3 are slidably mounted on the mounting plate 1. One end of each sliding plate 3 is tangent to the power output end of the rotating motor 2. Each sliding plate 3 has a transmission rack 31 at one end, which is connected to the power output end of the rotating motor 2. Each sliding plate 3 has a correction plate 32 on its top. The correction plate 32 has a correction groove 33 on its outer side for abutting the rotor shaft. The inner wall of the correction groove 33 is adapted to the outer wall of the rotor shaft.

[0032] Specifically, the power output end of the rotating motor 2 is fitted with a drive gear 21, and the transmission rack 31 extends along the length direction of the sliding plate 3, and the drive gear 21 meshes with the transmission rack 31.

[0033] Specifically, when the two correction plates 32 abut against each other, the two correction grooves 33 abut against each other and form a correction through hole for the rotor shaft to pass through. The inner wall of the correction through hole fits against the outer wall of the rotor shaft, and the central axis of the correction through hole and the central axis of the mounting plate 1 are both located on the same central axis.

[0034] Specifically, two push cylinders 11 are also provided on the outside of the mounting plate 1, and the two push cylinders 11 are symmetrically arranged on both sides of the outside of the mounting plate 1. The other ends of the two sliding plates 3 are respectively connected to the power output ends of the two push cylinders 11.

[0035] Specifically, the two sliding plates 3 are provided with mounting sliders 34 on the side facing the mounting plate 1, and the mounting plate 1 is provided with mounting rails 12 on the side facing the sliding plates 3. The mounting sliders 34 are slidably connected to the mounting rails 12.

[0036] Specifically, the power output end of the pushing cylinder 11 is connected to a fixed push block, which is fitted and connected to the other end of the sliding plate 3.

[0037] Specifically, the top of the mounting plate 1 is provided with several fixed support columns 13, which are evenly distributed on the top of the mounting plate 1 and are used to support the transport plate with the rotating iron core.

[0038] Example 1

[0039] To automate the correction of rotor shaft components, since the iron core assembly with rotor shaft components is prone to shaking and positional displacement when transported to another workstation, correction of the rotor shaft components is necessary to ensure concentricity between the rotor shaft components and the iron core assembly, thereby improving the assembly quality of the motor rotor. This embodiment includes: a mounting plate 1, a rotating motor 2, and two symmetrically arranged sliding plates 3. The rotating motor 2 is located directly below the mounting plate 1, with a mounting opening 10 at the center of the mounting plate 1. The mounting opening 10 is aligned with the power output end of the rotating motor 2, thus allowing the power output end of the rotating motor 2 to extend out. Both sliding plates 3 are slidably mounted on the mounting plate 1, with one end of each sliding plate 3 tangent to the power output end of the rotating motor 2. Each end of the sliding plate 3 is equipped with a transmission rack 31, which, through the transmission rack 31, interacts with the rotating motor 2... The power output end is connected to the drive. The power output end of the rotating motor 2 extends upward to one end between the two sliding plates 3 and is connected to the drive rack 31. Therefore, when the rotating motor 2 rotates, it drives the two sliding plates 3 to move towards or away from each other on the mounting plate 1. When the mounting plate 1 has a core assembly with a rotor shaft (i.e., the mounting plate 1 is located directly below the core assembly with the rotor shaft, and the mounting plate 1 and the core assembly are located on the same centerline), the two sliding plates 3 are provided with correction plates 32 on the top of the two sliding plates 3. Therefore, the two sliding plates 3 can move towards or away from each other on the mounting plate 1, and drive the correction plates 32 to move towards or away from each other. A correction groove 33 for abutting the rotor shaft is provided on the outer side of the correction plate 32. Therefore, the correction groove 33 abuts the rotor shaft for correction when moving towards each other, and the inner wall of the correction groove 33 is adapted to the outer wall of the rotor shaft.

[0040] It should be noted that in this embodiment, during the alignment process, the motor 2 is rotated counterclockwise, causing the two sliding plates 3 to move towards each other on the mounting plate 1, and the two correction plates 32 to move towards each other. During this process, the correction grooves 33 of the two correction plates 32 can abut against the rotor shaft until the correction grooves 33 on the two correction plates 32 merge to form a correction through hole that fits against the outer wall of the rotor shaft. At this time, the central axis of the correction through hole and the central axis of the iron core assembly are both located on the same central axis, thus completing the alignment action. After the alignment is completed, the motor 2 can be rotated clockwise. When the motor 2 rotates clockwise, the two sliding plates 3 move in opposite directions on the mounting plate 1, causing the two correction grooves 33 to loosen. After the alignment is completed, the rotor shaft iron core assembly directly enters the subsequent assembly station.

[0041] It should also be noted that, in order to align the mounting plate 1 directly below the iron core assembly with the rotor shaft for shaft alignment, the rotor shaft and the iron core shaft are basically transported to the next station via the transport plate after being pressed together. Therefore, the transport plate needs to be supported. Several fixed supports 13 are also provided on the top of the mounting plate 1. The fixed supports 13 are evenly distributed on the top of the mounting plate 1. Through the even distribution of several fixed supports 13, the fixed supports 13 can keep the transport plate stable and prevent tilting from affecting the alignment.

[0042] Example 2

[0043] To prevent the rotating motor 2 from meshing with the transmission rack 31, which would result in insufficient clamping force of the correction plates 32 on the two sliding plates 3 and prevent the two correction grooves 33 from correcting the rotor shaft inside the iron core, two push cylinders 11 are installed on the mounting plate 1. The power output ends of the two push cylinders 11 are connected to the other ends of the two sliding plates 3. By increasing the thrust of the push cylinders 11, it is ensured that when the two sliding plates 3 move towards each other, the two correction plates 32 completely abut against the rotor shaft, and the correction grooves 33 can completely fit against the outer wall of the rotor shaft, preventing the correction grooves 33 from failing to clamp the rotor shaft and affecting the correction effect.

[0044] It should be noted that by connecting a fixed push block (not shown in the figure) to the power output end of the pushing cylinder 11, the fixed push block (not shown in the figure) is attached to the other end of the sliding plate 3, thereby improving the force-bearing capacity.

[0045] In conjunction with the above embodiments, to ensure the smooth sliding of the sliding plate 3 and prevent the sliding plate 3 from getting stuck on the mounting plate 1, mounting sliders 34 are provided on the side of the two sliding plates 3 facing the mounting plate 1, and mounting rails 12 are provided on the side of the mounting plate 1 facing the sliding plates 3. The mounting sliders 34 are slidably connected to the mounting rails 12, thereby preventing the sliding plates 3 from getting stuck when they slide in opposite directions on the mounting plate 1.

In the above embodiments, the descriptions of each embodiment have different focuses; for parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

Furthermore, it is understood that the steps in the method of the present invention embodiments can be adjusted, combined, and deleted according to actual needs, and the structure in the device of the present invention embodiments can be combined, divided, and deleted according to actual needs.
