[0030] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0031] A motor is a device that uses electricity to generate a rotating magnetic field and acts on the rotor to form magneto-electric power rotation; it is mainly composed of a stator and a rotor. The magnetic field acts on the force of the current to make the motor rotate. The positioning fixture used for the production and assembly of the motor is used in the production of the motor to clamp the motor casing and install its internal structure.

[0032] In the related art, there is a positioning tool with an adjustment function, which is provided with an electric push rod and a clamp. The electric push rod is started by an external power supply, and the pads B and A on the surface of the clamp are clamped and fixed to the specified position of the casing surface of the motor 1. However, the appearance of the motor 1 itself is multi-mode and diverse, with a large difference in appearance and different sizes. This method is more suitable for fixing the square motor 1, and does not have a good fixing function for the cylindrical motor 1, and has certain limitations.

[0033] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a positioning fixture for motor production and assembly. When in use, it is only necessary to place the motor 21 on the support platform 12, let the clamping plate 28 fix the motor to be installed on the wrapping column, and then start the motor 21 to drive the fixing part 26 to move downward, thereby locking the spring rod 27, and finally achieving fixed installation of the motor.

[0034] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0035] Combination Figure 1-Figure 5The embodiment of the present application provides a positioning fixture for motor production and assembly, including a main body component 1; the main body component 1 includes: a base 11 whose upper surface is a bearing platform 12; a fixing component 2 is arranged on the base 11; the fixing component 2 includes: a motor 21 is arranged on the base 11; a threaded rod 22 is fixed to the power shaft of the motor 21; a connecting plate 23 is threadedly connected to the side surface of the threaded rod 22; a connecting plate 231 is plugged with the connecting plate 23; a U-shaped frame 25 is fixed on the connecting plate 231; a fixing piece 26 is slidably connected to the bottom of the U-shaped frame 25; a fixing plate 24 is movably connected to the base 11; a spring rod 27 is arranged on the fixing plate 24; a clamping plate 28 is hinged to one end of the spring rod 27; and a folded groove 29 is opened on the opposite surface of the fixing piece 26 and the spring rod 27.

[0036] When the produced motor needs to be assembled, the motor housing to be installed can be placed on the upper surface of the base 11, that is, on the bearing platform 12. A spring rod 27 is provided on the bearing platform 12, and a clamping plate 28 is provided on the spring rod 27. The motor housing is initially fixed by the elastic force generated by the clamping plate 28 and the spring rod 27. Since there are multiple groups of spring rods 27, the length can be calibrated by itself according to the different motor shapes. At the same time, since the clamping plate 28 is hinged to one end of the spring rod 27, the motor shape can be perfectly fitted and fixed. At this time, the motor 21 is started, and the motor is connected with a threaded rod 22. At the same time, a connecting plate 23 is provided on the side of the threaded rod 22, and then the connecting plate 231, the U-shaped frame 25, and the fixing piece 26 are connected in sequence. Finally, the fixing piece 26 is squeezed and contacted with the spring rod 27 under the drive of the motor, and the folding grooves on the opposite surface are tightly buckled together, so as to finally achieve tight fixation of the motor, so as to facilitate subsequent motor assembly and processing.

[0037] Specifically, the fixing member 26 is movably connected to the bottom of the U-shaped frame 25. The advantage of doing so is that since the length of each spring rod 27 is different according to the shape of the motor, it cannot be guaranteed that the folds are parallel to each other. At this time, the fixing member 26 needs to have a certain offset ability so that the folds of the fixing member 26 and the folds on the spring rod 27 are tightly squeezed together to achieve a firm fixation.

[0038] In some embodiments, a plurality of fixing members 26, spring rods 27, and clamping plates 28 are provided, so that the motor being installed during production can be fixed more stably.

[0039] In some embodiments, the cross section of the clamping plate 28 is V-shaped. The clamping plate 28 itself is hinged on the spring rod 27. The V-shaped shape allows for stable contact with the motor to achieve clamping and fixing.

[0040] In some embodiments, the clamping plate 28 is bonded with a rubber pad, which can not only protect the motor from scratches, but also increase the friction with the motor and increase the stability of the fixation.

[0041] In some embodiments, the main assembly 1 further includes: a limit rod 14 is disposed on the lower surface of the base 11, and a connecting plate 23 is movably connected to the side surface of the limit rod 14. The limit rod 14 is to ensure that the connecting plate 23 can move up and down more stably.

[0042] In some embodiments, the main assembly 1 further includes: a support roller 13 disposed on the base 11 to support the spring rod 27 and prevent the fixing member 26 from being damaged when pressed downward.

[0043] In some embodiments, an adjustment component 3 is also provided on the base 11, and the adjustment component 3 includes: a linear module 31 is provided on the base 11; a slider 32 is slidably connected to the linear module 31, and is respectively connected to the fixed plate 24 and the U-shaped frame 25; the adjustment component 3 can realize the distance between the clamping plate 28 and the fixing member 26 connected to the spring rods 27 on both sides, further increasing its adaptability to the fixed installation of motors of different sizes; at the same time, the adjustment plate 1 and the adjustment plate 2 are plug-in, and there will be no movement interference.

[0044] In some embodiments, multiple groups of adjustment components 3 are provided. Because fixing components such as spring rods 27 are provided on both sides, multiple adjustment components 3 are required for adjustment.

[0045] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

[0046] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
