DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Embodiment 1

[0046] like Figure 1 As shown, the rotor of the double twister traction motor of the present invention, the rotor 10 is composed of a central shaft 101, a plurality of magnetic steels 102, a plurality of silicon steel sheets 103, an inner steel sleeve 104, an outer steel sleeve 106, a plurality of inner guide bars 105 and a plurality of outer guide bars 107. Embodiment 2

[0047] On the basis of the above-mentioned embodiments, the present invention also discloses a rotor installation system for a two-for-one twister traction motor, which is used to install the internal structure of the rotor into an outer steel sleeve as a whole. Figures 2 to 9 As shown, the installation system 20 includes a main frame 21, a transmission component 22, a clamping component 23 and a working component 24. The main frame 21 is used to support and install the transmission component 22, the clamping component 23 and the working component 24.

[0048] like Figures 2 to 4As shown, the transmission assembly 22 includes a mounting frame 221, and the mounting frame 221 is connected to the lower part of the main frame 21. The mounting frame 221 is provided with a first slide rail 222, and the first slide rail 222 is connected with a plurality of upper support plates 224, and the upper support plates 224 are used to mount the rotor 10, and the upper support plates 224 move horizontally along the first direction X under the action of an external power source. A plurality of sliding blocks 223 are provided between the upper support plate 224 and the first slide rail 222, and the sliding blocks 223 limit the upper support plate 224 to move only along the first direction X, so as to prevent the upper support plate 224 from deviating when moving along the first direction X. Limiting members 226 are also installed on both sides of the first slide rail 222, and the limiting members 226 are used to limit the maximum travel of the upper support plate 224 on the first slide rail 222. The upper support plate 224 is also provided with an upper positioning member 225 and a lower positioning member 229, and the upper positioning member 225 is clamped on the side wall of the rotor 10. The bottom of the lower positioning member 229 is connected to a first slide bar 228, and the lower positioning member 229 is movably connected to the mounting frame 221 via the first slide bar 228. A first cylinder 227 is also provided at the bottom of the mounting frame 221, and the output shaft of the first cylinder 227 is connected to the lower positioning member 229. The first cylinder 227 controls the lower positioning member 229 to be located at the bottom of the rotor 10, and limits the downward movement of the rotor through the lower positioning member 229.

[0049] like Figure 5 As shown, the clamping assembly 23 includes a second slide rail 231, which is vertically connected above the mounting frame 221, and a sliding plate 232 is connected to the second slide rail 231. The clamping assembly 23 also includes a first motor 234, and the output shaft of the first motor 234 is connected to a ball screw 233. The ball screw 233 is connected to the sliding plate 232, wherein the first motor 234 is used to control the sliding plate 232 to move along the second slide rail 231. A slide groove 235 is installed on the sliding plate 232, and a left clamp 236'1 and a right clamp 236'2 are slidably connected to the slide groove 235. Both the left clamp 236'1 and the right clamp 236'2 have arc contact surfaces, and the left motor 237'1 and the right motor 237'2 are respectively installed on both sides of the slide slot 235. The left motor 237'1 and the right motor 237'2 correspondingly control the opening and closing of the left clamp 236'1 and the right clamp 236'2.

[0050] like Figure 6As shown, the working assembly 24 includes a working spindle 241, a slotted plate 242'1, a second slide bar 242'2 and a sleeve 243. The working spindle 241 is connected to the main frame 21. The sleeve 243 is fixedly mounted on the main frame 21, and the slotted plate 242'1 is connected to the sleeve 243 via the second slide bar 242'2. A second cylinder 248 is provided on one side of the slotted plate 242'1, and the output shaft of the second cylinder 248 is connected to an adjustment plate 245, and the adjustment plate 245 is slidably connected to the slotted plate 242'1, wherein the slotted plate 242'1 is installed with a first mandrel 246 and a second mandrel 247, and the working spindle 241 is connected to a mandrel 244, which is opposed to at least one mandrel.

[0051] In this embodiment, the outer steel sleeve 106 is clamped on one of the support plates 224, and the outer steel sleeve 106 is transmitted to the bottom of the working spindle 241 through an external power source and a matching sensor. At this time, the first cylinder 227 drives the lower positioning member 229 to limit the outer steel sleeve 106 from moving downward. The first motor 234 controls the sliding plate 232 and its upper parts to move downward, and then controls the left clamp 237'1 and the right clamp 237'2 to move toward each other through the left motor 236'1 and the right motor 236'2 to clamp the outer steel sleeve 106. After the outer steel sleeve 106 is completely fixed, the internal structure of the rotor is pressed into the outer steel sleeve 106 as a whole through the working spindle 241, thereby completing the installation of the rotor 10.

[0052] Furthermore, after the installation system 20 has been running for a long time, the sensitivity of the sensor detecting the movement of the upper support plate 224 may be problematic, or the left clamp 237'1 and the right clamp 237'2 may change, resulting in poor accuracy in rotor production. To this end, an image collector 249 is provided below the working spindle 241, and the image collector 249 is used to capture the center of the rotor 10, the center of the left clamp 237'1, and the center of the right clamp 237'2.

[0053] like Figures 7 to 9 As shown, the mounting system 20 is provided with a first positioning axis A and a second positioning axis B. The first positioning axis A is parallel to the first direction X, and the second positioning axis B is parallel to the second direction Y. The left clamp center point 30'1 and the right clamp center point 30'2 are set to always be located on the first positioning axis A, and the rotor center point 40 is set to always be located on the second positioning axis B (as shown in FIG. Figure 8 as shown).

[0054] like Fig. 9As shown, a first left-side adjusting cylinder 2210'1 and a first right-side adjusting cylinder 2210'2 are respectively installed on one side of the upper support plate 224. The first left-side adjusting cylinder 2210'1 and the first right-side adjusting cylinder 2210'2 are used to correct the sliding position of the upper support plate 224 along the first direction A. If the center of the rotor 40 deviates from the second positioning axis B by more than a preset value, the first left-side adjusting cylinder 2210'1 or the first right-side adjusting cylinder 2210'2 is controlled to correct its position accordingly.

[0055] like Figure 7 As shown, the left clamp 237'1 and the right clamp 237'2 are respectively connected to the second left adjusting cylinder 238'1 and the second right adjusting cylinder 238'2. The second left adjusting cylinder 238'1 and the second right adjusting cylinder 238'2 control the left clamp 237'1 and the right clamp 237'2 to move horizontally along the second direction Y, and correspondingly correct the sliding positions of the left clamp 237'1 and the right clamp 237'2 along the second direction Y. If the center of the left clamp 30'1 or the center of the right clamp 30'2 deviates from the first positioning axis A by more than a preset value, the second left adjusting cylinder 238'1 and the second right adjusting cylinder 238'2 are controlled to correct their positions accordingly.

[0056] Specifically, Figure 8 As shown, due to the external power source and the matching sensor that drive the upper support plate 224, the rotor center 40 is always located at the second positioning axis B, that is, the rotor center 40 is located within the error range of the installation accuracy of the second positioning axis B. When the installation system 20 runs for a long time and the sensor sensitivity decreases, the rotor center 40 shifts to the first rotor offset point 41 or the second rotor offset point 42 in the first direction X or the opposite direction of the first direction X. At this time, that is, the rotor center 40 deviates from the second positioning axis B by more than the preset value, and the position of the upper support plate 224 is corrected by starting the first left adjustment cylinder 2210'1 or the first right adjustment cylinder 2210'2. The upper support plate 224 has four chamfered surfaces, and the output shafts of the first left-side adjusting cylinder 2210'1 and the first right-side adjusting cylinder 2210'2 are respectively installed with the first wedge block 2211'1 and the second wedge block 2211'2, wherein, when correcting the sliding position of the upper support plate 224 along the first direction X, the first wedge block 2211'1 or the second wedge block 2211'2 contacts with the chamfered surface, and the position of the upper support plate 224 is adjusted by the inclined surface of the first wedge block 2211'1 or the second wedge block 2211'2, so that the center 40 of the rotor is always located on the second positioning axis B.

[0057] like Figures 7 and 8As shown, when the left clamp circle center 30'1 deviates to the first clamp offset point 31 or the second clamp offset point 32 in the second direction Y or the opposite direction of the second direction Y, that is, the left clamp circle center 30'1 deviates from the first positioning axis A by more than a preset value. At this time, the second left adjustment cylinder 238'1 controls the left clamp 237'1 to move horizontally along the second direction Y, corrects the position of the left clamp 237'1, and makes the left clamp circle center 30'1 always located on the first positioning axis A. This prevents the installation system from being loosened due to sensor sensitivity or clamp loosening after a long period of operation, resulting in reduced installation accuracy. Embodiment 3

[0058] Based on one or more of the above embodiments, the present invention specifically describes how the image collector can accurately capture the center of the rotor, the center of the left fixture, or the center of the right fixture. Figure 10 to Figure 11 As shown:

[0059] Step 1: The image collector collects the isometric projection image of the rotor, the left fixture or the right fixture;

[0060] Step 2: Convert the isometric projection image into an 8-bit grayscale single-channel image;

[0061] Step 3: Use the Canny algorithm to detect and enhance the image edges;

[0062] Step 4: Obtain the trajectory circle of the rotor, the left fixture or the right fixture;

[0063] Step 5: Compare the acquired trajectory circle with the reference trajectory circle;

[0064] Step 6: Determine the center of the rotor, left fixture or right fixture.

[0065] In this embodiment, if Fig.11 As shown, the specific steps of Step 5 are:

[0066] Step 5.1: Set the intersection point O between the center of the reference trajectory circle and the acquired trajectory circle;

[0067] Step 5.2: Draw a reference trajectory circle with radius OG through point O, and draw a line segment MN through point G that is tangent to the reference trajectory circle, with OG and MN perpendicular;

[0068] Step 5.3: Pick any point P on the trajectory circle, draw a perpendicular line to MN through point P, and the foot of the perpendicular line is P';

[0069] Step 5.4: Draw a perpendicular line P-P' through point O, with the foot of the perpendicular being P''.

[0070] Among them, if P-P'' is not greater than O-P'' and O-P'' is not greater than P'-P'', the comparison is completed.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
