Description

Technical Field

[0001] This utility model belongs to the field of motor processing technology, specifically referring to a welding fixture for motor stator cores. Background Technology

[0002] Stator core welding is a key process in motor manufacturing, and its core purpose is to ensure the stability, consistency and reliability of the core structure.

[0003] Currently, laser welding is mostly used for welding stator cores. Laser welding has a small heat-affected zone (only 1-3mm weld width) and a welding speed that is more than 6 times that of argon arc welding. Compared with the traditional argon arc welding method, it can reduce the need for post-weld grinding.

[0004] However, there are significant safety hazards associated with laser welding of stator cores: there is light radiation damage, and laser wavelengths of 400-1400nm may penetrate the eyeball, causing permanent retinal damage or even blindness if directly exposed, especially reflected light, which is equally dangerous; ultraviolet lasers (<400nm) may also cause photokeratitis and conjunctivitis (welder's flash), and long-term exposure increases the risk of cataracts. Traditional welding fixtures focus on positioning the electronic core, neglecting personnel safety; and adding welding protection structures can easily obstruct the welding position, increasing the difficulty of welding the stator core. Utility Model Content

[0005] This utility model aims to at least solve the problem of the lack of personnel safety protection equipment when using electronic iron core welding fixtures, and the problem that fixtures with protective equipment cannot guarantee the accuracy of stator iron core welding position.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model proposes a welding fixture for motor stator cores, including a base, a turntable rotating in the center of the base, on which the stator core is placed, and further comprising:

[0007] Equal-division rotation adjustment component: located below the turntable, driving the turntable to rotate evenly;

[0008] Iron core positioning assembly: four sets are arranged in a circular array on the turntable, and the four sets of iron core assemblies together clamp the stator iron core to be welded.

[0009] Openable protective component: Hinged on the base, it is transparent and encloses the iron core positioning component.

[0010] Furthermore, the openable protective assembly includes a semi-circular protective baffle fixed to one side of the base. Two sets of symmetrical arc-shaped transparent protective covers are also hinged to both sides of the base. After the two sets of protective covers are joined together, they wrap around the iron core positioning assembly and are pressed onto the protective baffle. The side opposite to the protective baffle is open.

[0011] Furthermore, the equal-division rotation adjustment assembly includes a four-division turntable rotating at the bottom of the turntable, and a drive turntable rotating at the bottom of the turntable. The other side of the drive turntable is provided with a rotation motor whose output shaft is connected to it by a key. The drive turntable is adapted to rotate with the four-division turntable.

[0012] Furthermore, the four-part turntable is provided with four sets of outwardly extending arc-shaped rotating rings, and the four sets of rotating rings are orthogonally arranged. An arc-shaped groove is provided between the rotating rings and the four-part turntable, and the drive turntable is adapted to the rotating rings.

[0013] Furthermore, the drive turntable is provided with a semi-circular rotating component, which is adapted to the rotating ring. The output shaft of the rotating motor is keyed to the rotating component. The drive turntable is also provided with two sets of rotating shafts. After the rotating shafts rotate, they are adapted to the groove, and the two sets of rotating shafts are adapted to the adjacent groove through rotation.

[0014] Furthermore, the core positioning assembly includes a cylinder fixed on the other side of the turntable. A clamping member is provided on one side of the cylinder. One side of the clamping member is an arc-shaped surface. Four sets of clamping members work together to clamp the electronic core. A gap is left between every two sets of clamping members to facilitate welding.

[0015] Furthermore, the opening is directly opposite the gap between the two sets of clamping members, and the gap between the clamping members remains facing the opening after the four-part turntable rotates.

[0016] The beneficial effects of this utility model by adopting the above structure are as follows:

[0017] 1. The semi-transparent, closable protective components are used to close the stator core during welding, reducing the light radiation damage to the human body from the laser and effectively protecting the eyes of the workers.

[0018] 2. By setting up an equally divided rotating component, the electronic iron core held by the iron core positioning component is rotated, and its gap position always faces the laser welding equipment, which improves the welding accuracy and increases the welding efficiency of the stator iron core.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 and Figure 6 :

[0028] A welding fixture for motor stator cores includes a base 1, a turntable 2 rotating in the center of the base 1, on which the stator core is placed. It also includes: a symmetrical rotation adjustment assembly 3 located below the turntable 2, driving the turntable 2 to rotate evenly; a core positioning assembly 4 mounted on the turntable 2 with four sets arranged in a circumferential array, the four sets of core assemblies clamping the stator core to be welded; and an openable protective assembly 5 hinged to the base 1, which is transparent and encloses the core positioning assembly 4. The openable protective assembly 5 includes components fixed to one side of the base 1. The semi-circular protective baffle 51 has two sets of symmetrical arc-shaped transparent protective covers 52 hinged to both sides of the base 1. After the two sets of protective covers 52 are joined together, they wrap around the iron core positioning component 4 and are pressed onto the protective baffle 51. The side opposite to the protective baffle 51 is open. After the two sets of protective covers 52 are closed, they wrap around the stator iron core component 4. The side opposite to the protective baffle 51 is set as an opening. When the iron core positioning component 4 drives the stator iron core to rotate, its welding position is always facing the opening, which protects the eyes of the workers and ensures that the welding work is not affected.

[0029] Please see Figure 3-5:

[0030] The equal-division rotation adjustment assembly 3 includes a four-division turntable 31 that rotates at the bottom of the turntable 2. The four-division turntable 31 is provided with four sets of outwardly extending arc-shaped rotating rings 311, and the four sets of rotating rings 311 are orthogonally arranged. An arc-shaped groove 312 is provided between the rotating rings 311 and the four-division turntable 311. A drive turntable 32 is also rotated at the bottom of the turntable 2. The drive turntable 32 is adapted to the rotating rings 311. A semi-circular rotating component 321 is provided on the drive turntable 32. The rotating component 321 is adapted to the rotating rings 311. A rotation motor 33 with an output shaft connected to it is provided on the other side of the drive turntable 32. The drive turntable 32 is adapted to the rotation of the four-division turntable 31. The output shaft of the rotation motor 33 is connected to the rotating component 321 by a key. The drive turntable 32 is also provided with two sets of rotating shafts 322. After the rotating shafts 322 rotate, they are adapted to the groove 312. The two sets of rotating shafts 322 are adapted to the adjacent groove 312 by rotation.

[0031] After the rotating motor 33 starts working, it drives the drive turntable 32 to rotate in a circle. At this time, the rotating part 321 and the rotating shaft 322 rotate accordingly. When a set of rotating shafts 322 contacts a groove 312, it is turned to rotate, causing the four-part turntable 31 to rotate. During the rotation, the rotating ring 311 is tangentially matched with the rotating part 321. When another set of rotating shafts 322 continues to rotate with the drive turntable 32, it slides and matches with the groove 312 in the adjacent position. It works with the first set of rotating shafts 322 to turn the four-part turntable 31 by 90°, changing the welding position of the turntable 2 so that the welding position is always facing the opening.

[0032] Please see Figure 2 :

[0033] The core positioning assembly 4 includes a cylinder 41 fixed on the other side of the turntable 2. A clamping member 42 is provided on one side of the cylinder 41. One side of the clamping member 42 is an arc-shaped surface. Four sets of clamping members 42 work together to clamp the electronic core. There is a gap between each pair of clamping members 42 to facilitate welding. The opening is directly opposite the gap between the two sets of clamping members 42, and the gap between the clamping members 42 remains facing the opening after the four-part turntable 31 rotates. The clamping member 42 corresponds to the rotating ring 311 on the four-part turntable 31. As the rotating ring 311 rotates, the turntable 2 drives the cylinder 41 and the clamping member 42 to rotate, so that the gap between the two sets of clamping members 42 is aligned with the opening to facilitate welding.
