Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figure 1-8As shown, a protective mechanism for an iron core S-shaped insulating paper comprises a fixed disk 1, wherein the upper side surface of the fixed disk 1 is provided with a plurality of first push blocks 6 in an annular array, and the upper side surface of the fixed disk 1 is provided with a plurality of first strip grooves in an annular array, the first push block 6 is slidably connected in the first strip groove and slides radially along the extension line of the center of the fixed disk 1, and the upper side surface of the first push block 6 close to one end of the center of the fixed disk 1 is provided with two parallel grooves 601, the two grooves 601 are arranged perpendicular to the extension line of the center of the fixed disk 1, and two clamping blocks 10 are symmetrically arranged in the two grooves 601 with the extension line of the center of the fixed disk 1 as the midline, and the lower sides of the two clamping blocks 10 are both threadedly connected with two rollers 12 that can slide in the grooves 601, so that the clamping blocks 10 can slide in the two grooves 601, and two springs 14 are arranged on the opposite sides of the two clamping blocks 10, and the two ends of the spring 14 are respectively connected to the opposite sides of the two clamping blocks 10, and the two clamping blocks 10 are symmetrically provided with U-shaped holes at one end close to the center of the fixed disk 1, and the two U-shaped holes can cooperate to form a through hole for copper wire to pass through;

[0026] The upper side of the first push block 6 is provided with a clamping assembly for bringing the two clamping blocks 10 closer to each other, and under the action of the clamping assembly, the two clamping blocks 10 cannot be separated from the groove 601;

[0027] The fixed disk 1 is provided with a first displacement assembly for pushing the first push block 6 to slide along the extension line of the center of the fixed disk 1 .

[0028] When in use, the staff places the fixed disk 1 on the upper side of the iron core, and pushes the first push block 6 to move toward the center of the fixed disk 1 along the radial extension line of the fixed disk 1 through the first displacement component. When the clamping block 10 moves to the top of the S-shaped insulating paper of the iron core, the U-shaped groove at the front end of the clamping block 10 is concentric with the S-shaped insulating paper. After that, the staff controls the two clamping blocks 10 to approach each other through the clamping assembly, so that the through hole formed by the two U-shaped grooves is smaller than the through hole formed by the folding of the S-shaped insulating paper. At this time, the inner side of the U-shaped groove is located on the inner side of the S-shaped insulating paper, so that the clamping block 10 limits the copper wire, so that the copper wire does not touch the inner side of the S-shaped insulating paper when inserted into the S-shaped insulating paper. After that, the staff inserts the copper wire into the S-shaped insulating paper through the two U-shaped grooves. Under the action of the clamping block 10, the copper wire does not contact the inner side of the S-shaped insulating paper during insertion, thereby preventing the copper wire from damaging the S-shaped insulating paper during the insertion process and ensuring the insulating effect of the S-shaped insulating paper. When the copper wire is connected, the staff releases the limit of the two adjacent clamping blocks 10 by the clamping assembly. At the same time, the two adjacent clamping blocks 10 are separated under the action of the elastic force of the spring 14 to prevent the clamping block 10 from damaging the copper wire when the staff removes the fixed disk 1. After that, the staff controls the first displacement assembly to return the first push block 6 to the initial position.

[0029] In this embodiment, the first displacement component includes a first adjustment turntable 2 rotatably connected to the upper side of the fixed disk 1 through a bearing. The first adjustment turntable 2 is provided with a plurality of through first arc-shaped grooves 201 in an annular array. A first follower post 7 that slides in the first arc-shaped groove 201 is threadedly connected to the upper side of the first push block 6. The number of the first follower posts 7 is the same as that of the first arc-shaped grooves 201 and they correspond to each other one by one. A first dial block 202 is integrally formed on the circumferential side of the first adjustment turntable 2. When adjusting the position of the first push block 6 in the first groove, the worker rotates the first adjustment turntable 2 through the first dial block 202. While the first adjustment turntable 2 is rotating, the first follower post 7 moves along the first arc-shaped groove 201, and at the same time, the first follower post 7 drives the first push block 6 to slide along the first strip-shaped groove, thereby realizing the adjustment of the position of the clamping block 10.

[0030] In this embodiment, the clamping assembly includes a follower disk 3 fixed to the upper side of the first adjustment turntable 2 and a plurality of second push blocks 8 arranged in an annular array on the upper side of the follower disk 3. A plurality of second strip-shaped grooves are provided in an annular array on the upper side of the follower disk 3. The second push blocks 8 are slidably connected in the second strip-shaped grooves and slide radially along the extension line of the center of the follower disk 3. A second displacement component for pushing the second push blocks 8 to slide is provided on the follower disk 3. One end of the second push block 8 close to the circle of the follower disk 3 is bolted with a wedge block 13 located on the lower side of the second push block 8. A V-shaped groove 1301 is provided at one end of the wedge block 13 close to the clamping block 10. Protrusions inserted into the V-shaped groove 1301 are integrally formed at one end of each clamping block 10 close to the wedge block 13. The sides of the two protrusions on the same first push block 6 are in contact. The protrusions are "right-angled triangles", and the inclined surfaces of the protrusions are attached to the inner sides of the V-shaped groove 1301. During use, the worker pushes the second push blocks 8 to slide in the second strip-shaped grooves along the extension line of the center of the follower disk 3 through the second displacement component. When the second push blocks 8 slide along the center of the follower disk 3, the protrusions of the clamping blocks 10 located in the V-shaped groove 1301 slide along the inner wall of the V-shaped groove 1301, so that the two clamping blocks 10 approach each other, thereby realizing the limitation of the copper wire and preventing the copper wire from damaging the S-shaped insulating paper.

[0031] In this embodiment, the second displacement component includes a second adjustment turntable 4 rotatably connected to the upper side of the follower disk 3 through a bearing. The second adjustment turntable 4 is provided with a plurality of through second arc-shaped grooves 301 in an annular array. A second follower post 9 that slides in the second arc-shaped groove 301 is provided on the upper side of the second push block 8. The number of the second follower posts 9 is the same as that of the second arc-shaped grooves 301 and they correspond to each other one by one. A second dial block 302 is provided on the circumferential side of the second adjustment turntable 4. During use, the worker rotates the second adjustment turntable 4 through the second dial block 302, and then the second follower post 9 slides in the second arc-shaped groove 301, so that the second follower post 9 drives the second push block 8 to slide along the extension line of the center of the follower disk 3, realizing the opening and closing control of two adjacent clamping blocks 10.

[0032] In this embodiment, triangular protrusions 1001 are integrally formed in the U-shaped grooves of the clamping blocks 10. The triangular protrusions 1001 are all located at the central positions of the opposite sides of the U-shaped grooves. During use, the triangular protrusions 1001 are located at the middle positions between two adjacent grooves of the S-shaped insulating paper, realizing the separation of the copper wires in two adjacent grooves, thereby improving the convenience of inserting the copper wires.

[0033] In this embodiment, a cover plate 5 is installed on the upper side of the second adjusting turntable 4 through bolts. During use, the cover plate 5 can prevent foreign objects from entering the interior of the protection mechanism, extending the service life of the protection structure.
