Specific embodiments

[0021] 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 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.

[0022] Such as Figure 1-6As shown in the figure, a super-low welding clamping tooling for a core copper wire includes a tray 1 and a core 2. The core 2 is fixedly placed in the tray 1. A radial clamping tooling 3 is sleeved on the upper side of the core 2. A circumferential clamping tooling 4 is arranged on the upper side of the radial clamping tooling 3. The structure and working principle of the circumferential clamping tooling 4 have been disclosed in the Chinese utility model patent with the patent name: An automatic installation device for a stator flat copper wire locking tooling, and the authorization announcement number: CN218775989U, so no more details will be described here. The radial clamping tooling 3 includes a fixed support plate 301, a rotating drive plate 302 rotatably connected to the lower side of the fixed support plate 301 through a bearing, and a support guide plate 303 fixedly connected to the lower side of the fixed support plate 301 through bolts. The rotating drive plate 302 is located between the fixed support plate 301 and the support guide plate 303. A plurality of radial chutes 306 are arranged in a circular array on the upper side of the support guide plate 303. A radial guard block 304 sliding along the radial extension line of the support guide plate 303 is slidably connected in the radial chutes 306. The support guide plate 303 and the radial guard block 30X are both provided with reference slots 307 having the same number and corresponding positions up and down. A plurality of arc slots 308 are arranged in a circular array through the rotating drive plate 302. A follower post 309 capable of sliding in the arc slots 308 is threadedly connected to the lower side of the radial guard block 304;

[0023] A locking assembly 7 for driving the rotation of the rotating drive plate 302 is arranged on the lower side of the fixed support plate 301.

[0024] During use, the staff places the core 2 on the tray 1, sleeved the radial clamping tooling 3 on the end of the core 2, and makes the copper wire at the end of the core 2 pass through the reference slots 307 on the radial guard block 304 and the support guide plate 303 correspondingly. Then, the circumferential clamping tooling 4 is moved to the upper side of the radial clamping tooling 3 through an external lifting mechanism, so that the circumferential clamping tooling 4 clamps the end of the core 2, making the copper wires at the end of the core 2 close together. Then, the staff drives the rotating drive plate 302 to rotate through the locking assembly 7, so that the follower post 309 slides along the arc slot 308, thereby driving the radial guard block 304 to slide towards the center of the support guide plate 303 along the radial extension line of the support guide plate 303. At this time, the reference slots 307 on the radial guard block 304 and the support guide plate 303 are misaligned with each other, and then the radial guard block 304 clamps the copper wire at the end of the core 2, which is convenient for subsequent cutting and welding work. At the same time, the radial clamping method can prevent the bending part of the copper wire at the end of the core 2 from being damaged, ensuring the reliability of the core 2 during subsequent use. When the cutting and welding of the copper wire at the end of the core 2 are completed, the staff reversely rotates the rotating drive plate 302 through the locking assembly 7, so that the reference slots 307 on the radial guard block 304 and the support guide plate 303 correspond to each other and are no longer misaligned. At this time, the radial clamping tooling 3 releases the limit on the end of the core 2, and the staff can remove the radial clamping tooling 3.

[0025] In this embodiment, two adjacent follower columns 309 are staggered, and two adjacent follower columns 309 are slidably connected in the same arc-shaped groove 308. During use, the staggered follower columns 309 enable the two follower columns 309 to rotate along the same arc-shaped groove 308, thereby reducing the number of arc-shaped grooves 308 and lowering the cost.

[0026] In this embodiment, the locking assembly 7 includes a fixed block 704 fixed to the inner side surface of the fixed support disk 301 by bolts, a sliding connection block 701 slidably connected to the lower side surface of the fixed support disk 301 through a slide rail, a rotating shaft bolt 702 penetrating through the sliding connection block 701, a hinged connecting rod 705 hinged to one end of the sliding connection block 701, and an outer ring hinged block 706 hinged to the other end of the hinged connecting rod 705. An arc-shaped through groove 708 is formed in the fixed support disk 301. The upper side surface of the outer ring hinged block 706 passes through the through groove 708 and is fixedly connected to the rotating drive disk 302 by bolts, and the outer ring hinged block 706 can slide circumferentially along the rotating drive disk 302 in the through groove 708. A threaded hole is formed through the fixed block 704. One end of the rotating shaft bolt 702 passing through the sliding connection block 701 is threadedly connected to the threaded hole. A square spring 703 is sleeved on the rotating shaft bolt 702. Two ends of the square spring 703 respectively abut against the sliding connection block 701 and the fixed block 704. When the radial clamping tooling 3 needs to clamp the end of the iron core 2, the worker rotates the rotating shaft bolt 702. Under the action of the thread, the sliding connection block 701 slides towards the fixed block 704. At the same time, the square spring 703 prevents the slight movement of the sliding connection block 701, improving the reliability of the sliding connection block 701 during use. The sliding connection block 701 simultaneously pushes the outer ring hinged block 706 to slide along the arc-shaped side surface of the through groove 708 under the action of the hinged connecting rod 705, thereby driving the rotating drive disk 302 to rotate, so as to realize the clamping of the copper wire at the end of the iron core 2 by the radial protection block 304.

[0027] In this embodiment, an inner guiding cylinder 305 is integrally formed on the inner side surface of the support guiding disk 303. When installing the radial clamping tooling 3, the worker first inserts the inner guiding cylinder 305 into the iron core 2, thereby realizing the guiding during the installation of the radial clamping tooling 3 and improving the convenience of installing the radial clamping tooling 3.

[0028] In this embodiment, a plurality of pin holes 5 are formed in a circumferential array on the upper side surface of the fixed support disk 301. A plurality of positioning pins 6 matching with the pin holes 5 are installed on the lower side surface of the circumferential clamping tooling 4 through bolts. The number of the pin holes 5 is the same as that of the positioning pins 6. During use, the positioning pins 6 and the pin holes 5 realize the positioning between the radial clamping tooling 3 and the circumferential clamping tooling 4, improving the convenience of connecting the radial clamping tooling 3 and the circumferential clamping tooling 4.

[0029] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
