[0002] The generator rotor is the rotating part of the generator. Its structure mainly consists of a rotor core, excitation windings, and supporting components. It generates a fixed magnetic field through DC excitation and interacts with the stator windings during rotation to generate electricity. In the traditional motor rotor core manufacturing process, rotor support rings need to be installed. The support rings themselves do not have positioning keys during installation. In the past, installation relied on the operator's visual observation, which made it easy for the installation to be misaligned and not meet the product's installation position accuracy requirements.

An adjustment groove is provided at the top of the front end plate, and an adjustment plate is slidably disposed in the adjustment groove.

[0023] The beneficial effects of this invention are:

[0024] 1. This type of rotor core support ring positioning and anti-misalignment device first determines the appropriate angle for fixing the rotor support ring. Then, the ball head is inserted into the shaft keyway to limit the anti-misalignment plate. At the same time, the anti-misalignment plate is moved to drive the connecting sleeve to rotate, so that the anti-misalignment groove on the anti-misalignment plate corresponds to the insertion groove corresponding to the determined installation angle. Then, two positioning connecting rods are placed in the insertion grooves along the two anti-misalignment grooves respectively, and the positioning connecting rods are prevented from misaligning through the two anti-misalignment grooves. The fixing seat is fixed to the rotor support ring, and then the positioning seat is fixed to the fixing seat. Then, the rotor support ring is put onto the outside of the rotor shaft, and the two positioning connecting rods are placed in the two positioning grooves respectively. In this way, the installation angle of the rotor support ring can be positioned, improving the positional accuracy during the installation process, and also preventing the position of the rotor support ring from shifting during installation.

[0025] 2. This type of rotor core support ring positioning and anti-foolproof device involves inserting the ball head into the shaft keyway until the fixing slide is also in. At this point, the wedge block and the ball head act as a limit, enabling rapid connection of the anti-foolproof plate to the rotor shaft. When the anti-foolproof plate is pushed inward with force until it can no longer move, pulling the anti-foolproof plate outward will remove the ball head from the shaft keyway, thus quickly separating the anti-foolproof plate from the rotor shaft.

[0026] 3. This type of rotor core support ring positioning and anti-foolproof device, by sliding the adjusting plate to a suitable position in the adjusting groove, and then fixing the position of the adjusting plate by cooperating with the locking nut and stud, can realize the adjustment of the length of the anti-foolproof plate, so as to facilitate use according to actual needs.

[0027] 4. This type of rotor core support ring positioning and anti-foolproof device, through the setting of the fine adjustment structure, turns the knob to drive the adjusting screw to rotate, the adjustment screw rotates and drives the adjusting cone block connected to it to move forward. Through the cooperation between the adjusting cone block and the cone surface of the fine adjustment block, the fine adjustment block can be pushed to move outward. In this way, through the movement of the two fine adjustment blocks, the width of the positioning groove can be finely adjusted, so as to meet the limiting cooperation of the positioning connecting rod according to actual needs.

Detailed Implementation

[0043] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0044] Example: Figures 1-4As shown, the present invention discloses a positioning and error-proof device for installing a rotor core support ring, comprising a rotor shaft 10 and a rotor core base 20 disposed at the bottom of the rotor shaft 10. An inverted T-shaped connecting sleeve 30 is fitted on the outside of the rotor shaft 10 and on top of the rotor core base 20. A plurality of insertion slots 21 are equidistantly provided along the circumferential direction at the outer edge of the top of the rotor core base 20, and a rotor lamination 40 is disposed on the top of the rotor core base 20 outside the connecting sleeve 30, with the outer tooth groove of the rotor lamination 40 corresponding to the insertion slots 21. A rotor support ring 50 is disposed on the top of the rotor shaft 10, and the rotor support ring 50 is first positioned by a positioning and error-proof mechanism 60 and then installed and fixed to the rotor shaft 10.

[0045] The positioning and error prevention mechanism 60 includes an error prevention baffle structure 61, a positioning connecting rod 62, and a positioning structure 63. The end of the error prevention baffle structure 61 is inserted into a semi-circular shaft keyway 31 on the connecting sleeve 30. The positioning structure 63 is fixed to the rotor support ring 50, and the error prevention baffle structure 61 and the positioning structure 63 are connected by the positioning connecting rod 62.

[0046] It should be noted that, first, the required angle for fixing the rotor support ring 50 is determined. Then, the end of the anti-foolproof baffle structure 61 is inserted into the shaft keyway 31 to connect the anti-foolproof baffle structure 61 to the rotor shaft 10, and the end of the anti-foolproof baffle structure 61 is aligned with the insertion slot 21 at the required angle. Then, the two positioning connecting rods 62 are passed through the anti-foolproof groove 6117 on the anti-foolproof baffle structure 61 and placed in the insertion slot 21. The anti-foolproof groove 6117 can prevent the positioning connecting rods 62 from being fooled. After fixing the positioning structure 63 to the rotor support ring 50, the rotor support ring 50 is then fitted onto the rotor shaft 10. The positioning structure 63 and the two positioning connecting rods 62 are used to limit the connection, thereby positioning the rotor support ring 50. After positioning, the position of the rotor support ring 50 is fixed. This improves the positional accuracy of the rotor support ring 50 during installation and also prevents the rotor support ring 50 from shifting during installation.

[0047] Among them, such as Figures 5-8 , Figure 10 and Figure 11As shown, the foolproof baffle structure 61 includes a foolproof baffle 611 with an adjustable length and a fixed sliding post 612 fixed to one end of the foolproof baffle 611. A slide rail 615 is fixedly connected to one end of the fixed sliding post 612, and a ball head 613 with a spherical outer wall is fixedly connected to one end of the slide rail 615. A sliding sleeve 614, with symmetrical and conical end faces centered between the fixed sliding post 612 and the ball head 613, is fitted onto the outside of the slide rail 615. The bottom surfaces of the fixed sliding post 612, ball head 613, sliding sleeve 614, and slide rail 615 are all cut along a horizontal centerline to form a flat surface and are flush with the bottom surface of the foolproof baffle 611. A receiving groove 616 is provided on the side of the ball head 613 near the sliding sleeve 614, which can accommodate half of the sliding sleeve 614 on the side near the ball head 613. The outer wall of the slide rail 615 is provided with multiple track grooves 617 at equal intervals along the circumferential direction. The bottom of the slide sleeve 614 is provided with a clearance groove 620 corresponding to the track groove 617. A limiting slide rod 618 is provided in the track groove 617. The two ends of the limiting slide rod 618 are fixedly connected to the fixed slide post 612 and the ball head 613, respectively. A return spring 619 is sleeved on the outside of the limiting slide rod 618. One end of the return spring 619 is fixedly connected to the ball head 613, and the other end is fixedly connected to the baffle 621 provided in the clearance groove 620 at the bottom of the slide sleeve 614. The baffle 621 is slidably connected to the limiting slide rod 618. A spring groove 32 is provided in the connecting sleeve 30 and communicates with the shaft keyway 31. A spring block 33 is provided in the spring groove 32. A wedge block 34 is fixedly provided at the bottom end of the spring block 33. The wedge block 34 is slidably disposed in the spring groove 32, and the inclined surface of the wedge block 34 faces the outside of the shaft keyway 31.

[0048] In detail, when the anti-foolproof baffle structure 61 needs to be connected to the rotor shaft 10, the anti-foolproof baffle 611 can be held and inserted into the shaft keyway 31 by hand, along with the ball head 613, the sliding sleeve 614, and the fixed sliding column 612. When the arc surface of the ball head 613 contacts the inclined surface of the wedge block 34, it will push the wedge block 34 upward. At this time, the wedge block 34 will compress and contract the spring block 33. When the ball head 613 continues to move forward until the arc surface no longer contacts the wedge block 34, the elasticity of the spring block 33 will push the wedge block 34 downward, pushing the wedge block 34 between the ball head 613 and the sliding sleeve 614. When the anti-foolproof baffle 611 is pulled outward, the anti-foolproof baffle 611 will not be pulled out of the shaft keyway 31 due to the limiting block between the wedge block 34 and the ball head 613, thus achieving the limiting and fixing of the position of the anti-foolproof baffle 611.

[0049] Furthermore, when it is necessary to separate the anti-foolproof baffle structure 61 from the rotor shaft 10, the anti-foolproof baffle 611 can be pushed forward. At this time, the ball head 613 will continue to move into the shaft keyway 31. During the movement of the ball head 613, the wedge block 34 will contact the left half of the arc surface of the sliding sleeve 614. The sliding sleeve 614 will then push the wedge block 34 upward. When the ball head 613 moves to the bottom of the shaft keyway 31, the wedge block 34 is pushed to the right side of the sliding sleeve 614 by the elastic action of the spring block 33. When the side arc surface contacts, the anti-foolproof baffle 611 can be pulled outward. The sliding sleeve 614 will continue to push the wedge block 34 upward. At the same time, the wedge block 34 will also exert a force on the sliding sleeve 614 to push the sliding sleeve 614 to move. When the wedge block 34 moves to the highest position of the top of the sliding sleeve 614, the left half of the sliding sleeve 614 is just pushed into the receiving groove 616. At this time, the top surface of the sliding sleeve 614 contacts the top surface of the ball head 613, and the anti-foolproof baffle structure 61 can be pulled out directly from the shaft keyway 31.

[0050] Specifically, simply put, the ball head 613 is inserted into the keyway 31 until the fixed slide column 612 is also in. At this time, the wedge block 34 limits the movement of the ball head 613, which enables the anti-fouling plate 611 to be quickly connected to the rotor shaft 10. When the anti-fouling plate 611 is pushed inward until it can no longer move, the ball head 613 can be removed from the keyway 31 by pulling the anti-fouling plate 611 outward, thus quickly separating the anti-fouling plate 611 from the rotor shaft 10.

[0051] It should also be noted that, through the setting of the limiting slide rod 618 and the return spring 619, when there is no force between the sliding sleeve 614 and the wedge block 34, the basic extension of the return spring 619 can create a gap between the sliding sleeve 614 and the ball head 613 that can accommodate the wedge block 34. In this way, the wedge block 34 can be pushed by the spring block 33 and placed between the ball head 613 and the sliding sleeve 614 to limit the anti-misalignment plate 611. Secondly, when the sliding sleeve 614 and the wedge block 34 are pushed into the receiving groove 616 by the force between them, the return spring 619 is in a compressed state until the anti-misalignment plate 611 is removed from the keyway 31. The elastic action of the return spring 619 will cause the sliding sleeve 614 to return to its original position and still maintain a certain gap with the ball head 613.

[0052] Among them, such as Figure 5As shown, the anti-misalignment plate 611 includes a front end plate 6111 fixed to the fixed sliding post 612 and a T-shaped rear end plate 6112. The top of the front end plate 6111 has an adjustment groove 6113, and an adjustment plate 6114 is slidably disposed within the adjustment groove 6113. One end of the adjustment plate 6114 is fixedly connected to the rear end plate 6112. Studs 6115 are fixedly disposed on both sides of the adjustment plate 6114 away from the rear end plate 6112. One end of the stud 6115 passes through a slot communicating with the adjustment groove 6113 and is threadedly connected to a locking nut 6116. Two anti-misalignment grooves 6117 are provided on the top side of the rear end plate 6112 away from the front end plate 6111. The anti-misalignment grooves 6117 are used to limit and prevent the positioning connecting rod 62 from misaligning.

[0053] It should be noted that by sliding the adjusting plate 6114 to a suitable position within the adjusting groove 6113, and then fixing the position of the adjusting plate 6114 by engaging the locking nut 6116 with the stud 6115, the length of the anti-fool plate 611 can be adjusted to facilitate use according to actual needs. By opening two anti-fool grooves 6117, when the two positioning connecting rods 62 are respectively passed through the two anti-fool grooves 6117 and placed in the insertion groove 21, the two positioning connecting rods 62 can play an anti-fool role.

[0054] Among them, such as Figure 1 , Figure 9 , Figure 12 and Figure 13 As shown, the positioning structure 63 includes multiple U-shaped fixed seats 631 and positioning seats 632. The fixed seats 631 are equidistantly arranged inside the rotor support ring 50 along the circumferential direction, and the positioning seats 632 are fixedly arranged at the top of the fixed seats 631. The positioning seats 632 are located at a height higher than the rotor support ring 50 and away from the fixed seats 631, and have two positioning grooves 633 that cooperate with the positioning connecting rods 62. The positioning seats 632 are provided with a fine-tuning structure 634 for fine-tuning the size of the groove opening of the positioning grooves 633. The fine-tuning structure 634 includes an adjusting screw 6341 and an adjusting cone 6342. One end of the adjusting screw 6341 is rotatably disposed within an adjusting chamber 6343 inside the positioning seat 632, while the knob at the other end is disposed outside the positioning seat 632. The adjusting cone 6342 is threadedly connected to the middle of the adjusting screw 6341. Fine-tuning blocks 6344 are provided on both sides of the adjusting cone 6342. The inner surface of the fine-tuning block 6344 slides against the conical surface of the adjusting cone 6342, while its outer surface is horizontally positioned and passes through the adjusting chamber 6343 into the positioning groove 633. An inverted T-shaped limiting slider 6345 is fixedly disposed in the middle of the inner surface of the fine-tuning block 6344, and the limiting slider 6345 slides within a limiting groove on the adjusting cone 6342.

[0055] In detail, first fix the fixed seat 631 to the rotor support ring 50, then fix the positioning seat 632 to the fixed seat 631, and finally put the rotor support ring 50 on the outside of the rotor shaft 10. Then, place the two positioning connecting rods 62, which are inserted into the insertion slot 21 at the required appropriate angle, into the two positioning slots 633 respectively. This can realize the positioning accuracy of the rotor support ring 50 and prevent the rotor support ring 50 from moving or shifting when fixing it.

[0056] Specifically, by setting the fine-tuning structure 634, turning the knob drives the adjusting screw 6341 to rotate. The rotation of the adjusting screw 6341 drives the adjusting cone block 6342, which is threaded to it, to move forward. Through the cooperation between the adjusting cone block 6342 and the cone surface of the fine-tuning block 6344, the fine-tuning block 6344 can be pushed to move outward. In this way, by moving the two fine-tuning blocks 6344, the width of the slot of the positioning groove 633 can be finely adjusted, so as to meet the limiting cooperation of the positioning connecting rod 62 according to actual needs.

[0057] Furthermore, through the cooperation of the limiting slider 6345 and the limiting groove, the fine-tuning block 6344 and the adjusting cone block 6342 can be connected. When the adjusting cone block 6342 moves, it can drive the fine-tuning block 6344 to move.

[0058] The working principle is as follows: First, determine the appropriate angle when fixing the rotor support ring 50. Then, insert the ball head 613 into the shaft keyway 31 to limit the anti-misalignment plate 611. At the same time, move the anti-misalignment plate 611 to drive the connecting sleeve 30 to rotate, so that the anti-misalignment groove 6117 opened on the anti-misalignment plate 611 corresponds to the insertion groove 21 corresponding to the determined installation angle. Then, place the two positioning connecting rods 62 into the insertion groove 21 along the two anti-misalignment grooves 6117 respectively. The positioning connecting rods 62 are prevented from misaligning through the two anti-misalignment grooves 6117.

[0059] Fix the fixed base 631 to the rotor support ring 50, then fix the positioning base 632 to the fixed base 631, and then fit the rotor support ring 50 onto the outside of the rotor shaft 10. At the same time, place the two positioning connecting rods 62 into the two positioning grooves 633 respectively. This can position the installation angle of the rotor support ring 50, improve the position accuracy during the installation process, and prevent the position of the rotor support ring 50 from shifting during installation.

[0060] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
