Description

Technical Field

[0001] The utility model relates to the technical field of flat wire motor welding, in particular to a flat wire motor welding disc. Background Art

[0002] Flat wire motors were originally high-power motors and high-power generator sets in the industrial field, and later extended to the vehicle field. Many application functions on vehicles use flat wire motors, such as: automotive generators, starters, EPS motors, main drive motors, P2 hybrid motors, etc. Due to the growing demand for electric vehicles, motor manufacturers are seeking more productive processes for high production capacity and high quality, so flat wire stators have largely prevailed. Manufacturers began to use compressed air to insert rectangular copper wires (called "flat copper wires" because of their shape) into the entire stator slot, instead of winding round copper wires around a single stator slot as before. The typical edge length of the rectangular cross-section of the flat copper wire is between 2 and 4 mm;

[0003] The stator of the flat wire motor needs to be fixed by tooling during welding. Most existing fixing methods use a single clamping unit in a turntable to fix the flat wire. However, if a clamping unit fails, the flat wire cannot be clamped, resulting in reduced welding quality and the inability to adjust the angle during welding. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-6 The utility model provides a flat wire motor welding disk, including a flexible clamping disk 1, a flexible lower mold disk 2 is rotatably provided on the top of the flexible clamping disk 1, a flexible upper mold disk 3 is rotatably provided on the top of the flexible lower mold disk 2, a first through hole 4 and a second through hole 5 for the flat wire to pass through are respectively provided on the surfaces of the flexible lower mold disk 2 and the flexible upper mold disk 3, the first through hole 4 and the second through hole 5 are both provided with notches 21, the directions of the notches 21 on the flexible lower mold disk 2 and the flexible upper mold disk 3 are opposite, the surface of the flexible lower mold disk 2 is provided with two first grooves 6, the surface of the flexible upper mold disk 3 is provided with two second grooves 7, and the surface of the flexible clamping disk 1 is provided with an adjusting mechanism, and the adjusting mechanism is respectively connected to one of the first grooves 6 and one of the second grooves 7.

[0023] See also Figure 1 , 3 , 4, 5 and 6, when the lower flexible mold plate 2 rotates, the lower flexible mold plate 2 can drive the first through hole 4 to rotate synchronously, and the upper flexible mold plate 3 can drive the second through hole 5 to rotate synchronously, so that Figure 3 and 4 For example, assuming that the lower flexible mold plate 2 rotates counterclockwise and the upper flexible mold plate 3 rotates clockwise, the notches 21 on the first through hole 4 and the second through hole 5 will be close to each other, thereby clamping and fixing the flat wire to facilitate welding of the flat wire.

[0024] The adjusting mechanism includes a fixed seat 8, a joint bearing 9, a rotating shaft sleeve 10, a lower mold rotating fixed block 11, an upper mold rotating fixed block 12 and a hexagonal bolt 13. The fixed seat 8 is installed on the surface of the flexible clamping disc 1. The two joint bearings 9 are rotatably arranged on both sides of the fixed seat 8. The two rotating shaft sleeves 10 are rotatably arranged inside the lower mold rotating fixed block 11 and the upper mold rotating fixed block 12. The hexagonal bolt 13 is rotatably arranged in the rotating shaft sleeve 10, and one end of the hexagonal bolt 13 is threadedly connected to one end of the joint bearing 9. The lower mold rotating fixed block 11 is fixed in the first groove 6, and the upper mold rotating fixed block 12 is fixed in the second groove 7.

[0025] See also Figure 1 and 3 After rotating the hexagonal bolt 13, the overall length between the hexagonal bolt 13 and the spherical bearing 9 will change. Since the horizontal position of the connection between the spherical bearing 9 and the fixing seat 8 is unchanged, when the overall length between the hexagonal bolt 13 and the spherical bearing 9 increases, the shaft sleeve 10 will move in the direction away from the spherical bearing 9. At this time, due to the change in the horizontal position of the spherical bearing 9, the shaft sleeve 10 will drive the lower mold rotating fixed block 11 or the upper mold rotating fixed block 12 to move, and the lower mold rotating fixed block 11 or the upper mold rotating fixed block 12 can rotate on the surface of the shaft sleeve 10 at this time, thereby driving the flexible lower mold plate 2 or the flexible upper mold plate 3 to rotate, thereby achieving the clamping of the flat wire.

[0026] It should be noted that when one of the hexagonal bolts 13 is rotated, only one of the flexible upper mold plate 3 or the flexible lower mold plate 2 can be driven to rotate. If the flexible upper mold plate 3 rotates and the flexible lower mold plate 2 does not move, the welding angle at the top of the flat wire will change, and the clamping force of the flat wire can be changed by adjusting the number of turns of the hexagonal bolt 13.

[0027] A limiting mechanism is provided on the flexible clamping disc 1, and the limiting mechanism includes a first limiting block 14, a lower die block 15, an upper die block 16, a positioning bolt 17 and a second limiting block 18. The lower die block 15 is installed in another first groove 6, and the upper die block 16 is installed in another second groove 7. The two first limiting blocks 14 and the two second limiting blocks 18 are all fixed on the surface of the flexible clamping disc 1, and the positioning bolt 17 is installed on the surface of the second limiting block 18.

[0028] See also Figure 1 and 3When the flexible upper mold plate 3 rotates, the flexible upper mold plate 3 can drive the second groove 7 to rotate synchronously. At this time, the second groove 7 can drive the upper mold stopper 16 to rotate synchronously. The same is true for the lower mold stopper 15. When the upper mold stopper 16 rotates, the maximum stroke of the upper mold stopper 16 is the arc path from one end of the positioning bolt 17 to the first limit block 14. By rotating the positioning bolt 17, the arc length of the arc path can be changed, thereby adjusting the maximum rotation angle of the flexible upper mold plate 3 and the flexible lower mold plate 2.

[0029] A height limiting mechanism is arranged on the flexible clamping disc 1, and the height limiting mechanism includes three height limiting blocks 19. The height limiting blocks 19 are fixed on the surface of the flexible clamping disc 1, and the tops of the flexible upper mold disc 3 and the flexible lower mold disc 2 are in contact with the bottoms of the height limiting blocks 19. One side of the height limiting block 19 is arranged as an arc surface, and the arc surface is flush with the inner wall of the flexible upper mold disc 3.

[0030] See also Figure 1 and 3 The height limiting block 19 can limit the upper flexible mold plate 3 and the lower flexible mold plate 2 in the vertical direction, so that the upper flexible mold plate 3 and the lower flexible mold plate 2 can only rotate in the current plane, thereby ensuring the accuracy of the upper flexible mold plate 3 and the lower flexible mold plate 2 when clamping the flat wire.

[0031] A guide mechanism is provided at the bottom of the flexible clamping disc 1 , and the guide mechanism includes three arc-shaped guide blocks 20 . The three arc-shaped guide blocks 20 are concentrically fixed to the bottom of the flexible clamping disc 1 , and the end surfaces of the three arc-shaped guide blocks 20 are arranged at the same height.

[0032] See also Figure 2 The three arc-shaped guide blocks 20 can limit the flat wire motor from the side thereof, so that the flat wire motor is concentric with the flexible clamping disc 1, and the flat wire can normally enter the first through hole 4 and the second through hole 5 to achieve accurate welding.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
