[0002] A motor, also known as an electric machine, is a device that can convert electrical energy into mechanical energy. The motor is mainly composed of a housing, a stator or magnet, a rotor, brushes, end covers, a shaft, bearings and other components. During assembly, the stator or magnet, rotor, brushes and other components need to be assembled in the housing in sequence.

[0003] With the development of technology, the assembly of motors has gradually been replaced by machines instead of manual labor, realizing automated assembly to improve assembly efficiency.

[0004] In the process of mechanical automated assembly, the shell needs to be fixed first, and then the various components are assembled into the shell through a robotic arm or other equipment. However, when the existing motor assembly equipment fixes the shell, the workers place the shell on the assembly equipment for fixation, and the area where the shell is placed each time will be different. However, the equipment has no deviation correction function when automatically fixing the shell, resulting in an inability to locate the designated area. The position deviation of each fixation is large, and there are also large errors in the later assembly, which affects the working performance of the motor.

[0005] In view of this, we propose an automatic positioning device for motor assembly. Utility Model Content

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0029] Embodiment 1:

[0030] Reference Figure 1-Figure 6, an automatic positioning device for motor assembly, comprising a workbench 1, a fixed plate 2 is fixedly connected to the workbench 1; a positioning plate 3 is slidably connected to the workbench 1, the positioning plate 3 and the fixed plate 2 are on the same straight line, and a driving mechanism is also provided on the workbench 1, the driving mechanism is used to drive the positioning plate 3 to move; two sets of inclined plates 201 are installed on the workbench 1, the two sets of inclined plates 201 are inclined symmetrically designed, and the two sets of inclined plates 201 are distributed on both sides of the fixed plate 2, such as Figure 3 The two groups of inclined plates 201 are symmetrical around the fixed plate 2 and are close to one end of the fixed plate 2 and relatively close to each other.

[0031] During assembly, the worker places the shell between two sets of inclined plates 201, and then drives the positioning plate 3 to move toward the fixed plate 2 through the driving mechanism to fix the shell between the positioning plate 3 and the fixed plate 2. In the process of the positioning plate 3 pushing the shell to be fixed, under the action of the inclined plates 201 on both sides, it will automatically move toward the middle of the fixed plate 2, so that it is fixed in the center of the positioning plate 3 and the fixed plate 2 every time, playing the role of automatic positioning; then the various components are assembled into the shell through a robotic arm or other equipment.

[0032] During the fixing process, the inclined plates 201 on both sides of the shell play a role in correction. Even if the workers place the parts in different areas each time, the inclined plates 201 can correct the deviation by themselves, and then fix the shell to the specified position, which plays a role in automatic positioning. In the later assembly, the assembly accuracy is guaranteed, and the working performance of the motor is ensured after assembly.

[0033] The opposing surfaces of the positioning plate 3 and the fixing plate 2 are designed to conform to the outer shape of the housing, and can be either planar or arc-shaped according to the outer shape of the housing.

[0034] like Figure 1 , Figure 3 , Figure 4 A first motor 203 is fixedly connected to the workbench 1, and a first threaded rod 204 is fixedly connected to the output end of the first motor 203. The first threaded rod 204 is rotatably connected to the workbench 1. The side walls of the two sets of inclined plates 201 are fixedly connected with connecting plates 202. The connecting plates 202 are located on the outer side walls of the inclined plates 201, and the connecting plates 202 are threadedly connected to the first threaded rod 204.

[0035] The first threaded rod 204 is a bidirectional threaded rod, and the threads at both ends have the same parameters except for the rotation direction.

[0036] According to different batches of shells, if they are of different sizes, the distance between the two sets of inclined plates 201 can be flexibly adjusted to ensure that the shell can be fixed between the positioning plate 3 and the fixing plate 2.

[0037] When adjustment is required, the first motor 203 is started to drive the connecting plate 202 to move through the first threaded rod 204, thereby driving the two sets of inclined plates 201 to move closer or farther away, thereby achieving the purpose of adjusting the spacing.

[0038] like Figure 3 and Figure 4 The tilting plate 201 and the connecting plate 202 are both made of metal and are heavy. The tilting plate 201 is located at an end away from the first threaded rod 204. When the first threaded rod 204 rotates, the connecting plate 202 will not rotate due to its own gravity and the lever factor, so the tilting plate 201 will only make a translational motion.

[0039] like Figure 1-Figure 6 The driving mechanism includes a second motor 5 , which is fixedly connected to the bottom of the workbench 1 , and an output end of the second motor 5 is fixedly connected to a second threaded rod 501 , which rotates at the bottom of the workbench 1 .

[0040] A push plate 302 is slidably connected to the workbench 1, and the push plate 302 is threadedly connected to the second threaded rod 501; a slide groove 301 is provided on the workbench 1, and the positioning plate 3 and the push plate 302 are both engaged in the slide groove 301; the positioning plate 3 and the push plate 302 are connected by a spring 402.

[0041] like Figure 5 When the positioning plate 3 needs to be driven to move, the second motor 5 is started to drive the push plate 302 to move through the second threaded rod 501, and then Figure 4 The push plate 302 drives the positioning plate 3 to move through the spring 402, thereby achieving the purpose of driving the positioning plate 3 to move.

[0042] The spring 402 serves the purpose of buffering, thereby preventing the positioning plate 3 from exerting an excessive force on the housing.

[0043] When the housing needs to be loosened, the second motor 5 can be reversed.

[0044] like Figure 3 and Figure 4 The side wall of the positioning plate 3 is fixedly connected with the first sleeve 4, and the side wall of the pushing plate 302 is fixedly connected with the second sleeve 401; the first sleeve 4 and the second sleeve 401 are sleeved together, that is, the first sleeve 4 and the second sleeve 401 are sleeved together and can slide against each other.

[0045] The spring 402 is located inside the first sleeve 4 and the second sleeve 401 .

[0046] The first sleeve 4 and the second sleeve 401 can prevent the spring 402 from being exposed. At the same time, the first sleeve 4 and the second sleeve 401 also make the push plate 302 and the positioning plate 3 form a whole, thereby preventing the push plate 302 and the positioning plate 3 from tilting when the second threaded rod 501 drives the push plate 302 to move.

[0047] like Figure 4 Grooves 6 are provided on both sides of the positioning plate 3, which can prevent the positioning plate 3 from interfering with the inclined plates 201 on both sides during the positioning process of the plate 3.

[0048] like Figure 4 , the top of the inclined plate 201 can be in contact with the top of the groove 6.

[0049] The so-called top of the inclined plate 201 can be in contact with the top of the groove 6, which means that when the positioning plate 3 moves toward the fixed plate 2, when the positioning plate 3 moves above the fixed plate 2, the top of the inclined plate 201 is in contact with the top of the groove 6. At this time, the inclined plate 201 also plays a supporting and limiting role, and cooperates with the slide groove 301 to further prevent the positioning plate 3 from tilting.

[0050] At this time, when adjusting the spacing between the inclined plates 201, in order to improve stability, the positioning plate 3 can be first moved to the top of the inclined plate 201 through the driving mechanism, and the inclined plate 201 can be stuck in the groove 6, and then the spacing between the inclined plates 201 can be adjusted through the first motor 203 so that the inclined plate 201 can slide horizontally in the groove 6.

[0051] like Figure 6 A bonding plate 502 is fixedly connected to the bottom of the positioning plate 3 , and the bonding plate 502 is bonded to the lower bottom surface of the workbench 1 .

[0052] The laminating plate 502 is detachably fixed to the bottom of the positioning plate 3 by screws, and the laminating plate 502 and the lower bottom surface of the workbench 1 can slide relative to each other.

[0053] The laminating plate 502 plays a limiting role, so that the positioning plate 3 is engaged on the workbench 1 to improve stability.

[0054] Embodiment 2:

[0055] Reference Figure 1-Figure 6 , which is basically the same as Example 1. On the basis of Example 1, the overall technical solution is further optimized.

[0056] The present embodiment discloses an automatic positioning device for motor assembly, which also includes a cylinder 101. The workbench 1 is disc-shaped and rotates on the top of the cylinder 101. A third motor 7 is fixedly connected inside the cylinder 101, and the output end of the third motor 7 is fixedly connected to the workbench 1.

[0057] At this time, in the automatic positioning device for motor assembly disclosed in Embodiment 1, except for the workbench 1, the other corresponding structures can be set to 3-6 groups, such as Figure 3 , distributed in a circle on workbench 1.

[0058] At this time, during work, after starting one set of fixing plates 2 and positioning plates 3 to fix the shell, the workbench 1 is driven to rotate by the third motor 7, rotated to the next station, and then assembled. When it rotates to the last station and the assembly is completed, the shell is released.

[0059] Furthermore, it is possible to realize positioning, fixing and assembly on a workbench 1 through multiple sets of structural designs and then rotate the workbench 1, thereby achieving simultaneous positioning, fixing and assembly, thereby improving assembly efficiency.

[0060] The second motor 5 is installed on the lower surface of the workbench 1 and is hidden by the cylinder 101 to further improve the aesthetics.

[0061] like Figure 4 A boss 102 is provided on the inner wall of the cylinder 101 , and the workbench 1 rotates on the boss 102 . The support of the boss 102 makes the workbench 1 rotate more stably.

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
