Further, although the terms used in the present invention are selected from publicly known and used terms, some of the terms mentioned in the description of the present invention may be selected by the applicant at his or her discretion, the detailed meanings of which are described in relevant parts of the description herein. Furthermore, it is required that the present invention is understood, not simply by the actual terms used but by the meaning of each term lying within.

The basic principles and preferred embodiments of the present invention are discussed in more detail with reference to the accompanying drawings. Referring first to fig. 1 and 2, the motor assembling device of the present invention mainly comprises: structural frame 10, pneumatic jacking assembly 20, centering assembly 30.

Structural framework 10 constitutes the utility model discloses a motor attaches together the main part of equipment, provides the installation benchmark for each other subassembly. The structural frame 10 has a mounting panel 11. According to one embodiment, the mounting panel 11 is made of a non-magnetic material, preferably polyoxymethylene sheet. The mounting panel 11 is provided with a hole suitable for the rotor sleeve 31 of the centering assembly 30 to pass through.

The pneumatic jacking assembly 20 is arranged in the structural frame 10 and comprises a linear guide rail 21, a support plate 22, a fisheye joint 23, a waist-shaped groove plate 24, a V-shaped plate assembly 25 and a cylinder 26. The air cylinder 26 is attached to the bottom of one of the side brackets of the structural frame 10. The linear guide rail 21 is disposed on the side frame and can slide up and down along the side frame. The piston rod of the cylinder 26 is connected to one end of the V-shaped plate assembly 25 via the fisheye joint 23, and the other end of the V-shaped plate assembly 25 is connected to the waist-groove plate 24 via a roller 255, such that the roller 255 can slide within the waist-groove plate 24. The support plate 22 is fixed to the top of the waist groove plate 24, and one side of the waist groove plate 24 is fixed to the linear guide 21.

The pneumatic jacking assembly 20 is powered by a cylinder 26 to provide the lifting motion of the whole structure. The V-shaped plate assembly is pushed to rotate around the connecting shaft by the telescopic motion of the cylinder 26, meanwhile, the other end of the V-shaped plate assembly 25 is connected with a follow-up roller 255, and the roller 255 drives the waist groove plate 24 to move in the vertical direction along the linear track 21, so as to drive the rotor guide sleeve placed on the supporting plate 22 to move up and down.

The centering assembly 30 includes a rotor sleeve 31 and a stator fixing tool 32. The centering assembly 30 provides precise centering guidance for the stator and rotor, ensuring centering requirements of the stator and rotor during assembly. And the inner hole of the stator base and the outer diameter of the rotor guide sleeve are accurately positioned. The stator is centered with the stator base through the spigot surface, and the rotor is centered with the rotor guide sleeve.

As shown in fig. 1, the stator fixing tool 32 is fixed to the mounting panel 11 of the structural frame 10. One end of the rotor sleeve 31 is connected to the stator fixing tool 32 and the other end is located on the support plate 22.

Based on the above structure, the piston rod of the cylinder 26 can perform the reciprocating motion of ejection and recovery, and drives the waist groove plate 24 and the support plate 22 to perform the lifting motion along the linear guide rail 21. For example, fig. 4 shows the waist slot plate 24 and the support plate 22 as they are raised to the top.

As shown in fig. 2 and 4, the cylinder 26 as a whole forms an acute angle with a horizontal plane at the base of the structural frame 10. In other words, the cylinders 26 are arranged substantially horizontally, rather than vertically as is conventional, thus effectively utilizing the bottom space of the structural frame 10.

During operation, the cylinder 26 extends the piston rod through the rodless chamber intake and the rod chamber exhaust. The V-plate assembly 25, which is connected to the piston rod by means of the fish-eye joint 23, will produce a pushing force upwards and to the left, see fig. 4. Then, the thrust is resolved into a lifting force of the linear guide rail 21 and a leftward sliding force of the roller 255 in the lumbar plate 24 by the foot seat. The linear guide 21 slides upward while the piston rod of the cylinder 26 is pushed out, and the roller 255 connected to the V-shaped plate assembly 25 simultaneously slides leftward within the kidney slot plate 24. At the same time as the piston rod is fully pushed out, the linear guide 21, the V-plate assembly 25, just reaches the end of the stroke. At the moment, the waist groove plate 24 is perpendicular to the linear guide rail 21, the support plate 22 is installed above the waist groove plate 24, and the rotor guide sleeve is upwards jacked through the through hole of the stator fixing tool base and is perpendicular to the support plate 22.

Turning to FIG. 3, V-shaped plate assembly 25 includes a long side 251, a short side 252, and a through hole 253 at the junction of long side 251 and short side 252. The three axes of rotation are at the three vertices of the V-plate assembly 25, respectively, taking maximum advantage of the asymmetric design of the build stroke. The through hole 253 is connected to the base of the structural frame 10 via a hinge 254 (one of the rotation shafts). The end of the short side 252 is connected to the piston rod of the cylinder 26 via a fish eye joint 23. The ends of the long side 251 are connected to the waist groove plate 24 via rollers 255. In other words, the piston rod of the cylinder 26 is mounted in the middle of the rotating shaft through the fisheye joint 23, and drives the V-shaped plate assembly 25 to rotate.

The ratio of the length of the long side to the short side is preferably controlled to be about 2. Compare in traditional cylinder application (rely on the cylinder stroke to carry out equal stroke and syntropy motion promptly), the utility model discloses a scheme has utilized the bottom space of workstation more effectively, reserves upper platform and is used for the assembly, has avoided the interference of mechanisms such as work piece and cylinder.

In the embodiment shown in fig. 5, the stator fixing tool 32 of the centering assembly 30 has a U-shaped groove 321, a spigot surface 322, a stator fixing block 323, and an oilless bushing 324.

Wherein, the stator fixing tool 32 is fixed on the mounting panel 11 by means of the U-shaped groove 321, and the stator fixing tool 32 suitable for the motor stators of different models can be quickly replaced by the U-shaped groove 321. The stator fixing block 323 is installed at a side of the spigot surface 322 for positioning the stator. The stator fixing block 323 allows the stator to be fixed therein by rotation, so as to fix the stator. Further, an oilless bushing 324 is provided in an opening in the center of the stator fixing tool 32 to allow the rotor sleeve 31 to slide up and down in the oilless bushing 324.

In addition, in one embodiment, oilless copper bushings are embedded in an inner hole of the stator fixing tool and an inner hole of the rotor sleeve, so that the problem that the surface of the rotor shaft is scratched due to friction between the rotor shaft and the rotor sleeve is solved. Finish machining is carried out again after the bushing is installed, concentricity of the stator and the stator fixing tool, the stator fixing tool and the rotor sleeve, the rotor and the rotor sleeve and the like after being matched for many times is ensured, and quality problems of the stator and the rotor of the motor caused by non-concentricity in the assembling process are greatly improved.

To sum up, the motor of this application attaches together equipment has guaranteed the upper and lower concentric state when the rotor gets into stator bearing room through utilizing cylinder, waist frid and linear guide, has carried out the innovation on the use method of traditional cylinder, has greatly utilized the inside limited space in space, has effectively satisfied the comfortable operation height of factory's operator, has reduced owing to attach together scratch and the bearing abnormal sound that the in-process caused because of the decentraction, has changed traditional assembly methods.
