Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 9 As shown, the present invention provides a welding device for welding a motor coil, comprising a motor coil body 1, a wire 2 is wound around the motor coil body 1, and further comprising:

[0038] A limiting component 3, on which the end of the wire 2 is sleeved;

[0039] The transmission assembly 6 is fixedly mounted on the top of the limiting assembly 3;

[0040] A stabilizing component 4, wherein the stabilizing component 4 is sleeved on the transmission component 6;

[0041] A clamping assembly 5, wherein the clamping assembly 5 slides on the transmission assembly 6;

[0042] The limiting assembly 3 includes a first fixing plate 31, a circular hole 35 is formed on the first fixing plate 31, and the wire 2 is sleeved in the circular hole 35;

[0043] The transmission assembly 6 includes a guide rod 66 fixedly mounted on the top of the first fixed plate 31, a support frame 61 is fixedly mounted on the top of the guide rod 66, a movable rod 63 is movably sleeved in the middle of the support frame 61, a movable ring 64 is movably sleeved on the top of the movable rod 63, a spiral groove 65 is formed on the outside of the movable rod 63, and a protrusion 62 is fixedly mounted on the inner wall of the middle of the support frame 61;

[0044] The protrusion 62 is engaged with the inside of the movable rod 63;

[0045] In the initial state, the projection 62 is located at the upper end of the spiral groove 65;

[0046] The clamping assembly 5 includes a second fixing rod 51 fixed to the bottom of the movable rod 63 . A through hole is formed in the middle of the second fixing rod 51 , and the end of the wire 2 is sleeved in the through hole.

[0047] The ends of the two wires 2 that need to be connected are respectively sleeved in the two circular holes 35 and the two through holes on the second fixing rod 51, and the wires 2 are fixed by the limiting assembly 3 and the clamping assembly 5. Since the protrusion 62 is engaged in the spiral groove 65 and is located at the upper end of the spiral groove 65, the movable rod 63 is pulled up to move up and rotate and drive the second fixing rod 51 to rotate under the cooperation of the protrusion 62 and the spiral groove 65. Since the two wires 2 are sleeved in the two through holes on the second fixing rod 51, the lower ends of the two wires 2 are limited by the limiting assembly 3. The two wires 2 are knobbed together by rotating the second fixing rod 51 upward, so that the two wires 2 are approximately twisted. The two wires 2 can be welded with the help of welding equipment, thereby avoiding manual knob rotation and preventing the wire from pricking the hand. Welding by turning the knobs of the two wires 2 can improve the stability of the motor coil welding.

[0048] like Figure 1-Figure 3 As shown, the limiting assembly 3 also includes a first movable rod 37 sleeved in the first fixed plate 31, the first movable rod 37 is connected to the outside of the first connecting rod 33, one end of the first connecting rod 33 is fixedly mounted with the first connecting plate 32, and both ends of the side of the first connecting plate 32 are fixedly mounted with first baffles 34, and after the first baffle 34 is combined with the first fixed plate 31, a circular hole 35 is left inside;

[0049] Both ends of the first movable rod 37 are in arc shape. A first spring latch 36 is fixedly mounted inside the first fixing plate 31 . A groove for the first spring latch 36 to engage is formed outside the first movable rod 37 .

[0050] The first connecting plate 32 is pulled to move the two first baffles 34 away from the first fixed plate 31. At the same time, the first connecting rod 33 and the first movable rod 37 move the first spring pin 36 out of the groove outside the first movable rod 37. After the first baffle 34 moves, the circular hole 35 is in an open state, and the wire 2 can be placed inside the circular hole 35. At the same time, the first baffle 34 is pushed to move in the opposite direction to combine with the first fixed plate 31 to form the circular hole 35, and the first baffle 34 is fixed by engaging the first spring pin 36 in the groove outside the first movable rod 37.

[0051] like Figure 4-Figure 8 As shown, the clamping assembly 5 also includes a limiting hole opened on the second fixing rod 51, and a guide groove 55 is opened on the second fixing rod 51. A second baffle 58 is slidably arranged in the guide groove 55. After the second baffle 58 is combined with the second fixing rod 51, the limiting hole is left inside, and the four corners of the second fixing rod 51 are fixed with sliders 53;

[0052] A second movable rod 512 is movably sleeved on the side of the second fixed rod 51, and a second connecting rod 511 is connected to the side of the second movable rod 512. The second connecting rod 511 is connected to the second baffle plate 58 through a second connecting plate 57. A circular groove is formed on the outside of the second movable rod 512, and a second spring latch 513 engaged in the circular groove is provided inside the second fixed rod 51.

[0053] Both ends of the second movable rod 512 are in arc shape;

[0054] In the initial state, the second spring latch 513 is engaged in the outer circular groove of the second movable rod 512;

[0055] The second baffle plate 58 and the inner wall of the limiting hole are respectively provided with a second roller 56 and a first roller 54 . The second baffle plate 58 and the inner wall of the limiting hole are respectively provided with a second support pad 59 and a first support pad 52 .

[0056] By pulling the second connecting plate 57, the two second baffles 58 move toward the outer end along the guide groove 55, and at the same time, the second spring latch 513 is disengaged from the circular groove outside the second movable rod 512. When the second baffle 58 is away from the second fixed rod 51, the limiting hole is in an open state, and the upper end of the wire 2 can be placed in the limiting hole, and the second baffle 58 and the second fixed rod 51 are pushed to form the limiting hole, and the second spring latch 513 is engaged in the circular groove to fix the second baffle 58;

[0057] After the wire 2 is fixed by the limit assembly 3 and the clamping assembly 5, the movable rod 63 is pulled upward to drive the second fixing rod 51 to rotate and perform knob processing on the wire 2. Since the wire 2 is composed of multiple winding copper wires, the wire 2 is squeezed by the first roller 54 and the second roller 56 during the upward movement of the second fixing rod 51, so that the multiple copper wires are gathered to the middle. The winding is more stable and tidy during the clamping knob, which can improve the welding quality.

[0058] like Figure 2 and Figure 4 As shown, the stabilizing assembly 4 includes a stabilizing frame 41 that slides outside the guide rod 66 , and an inner wall of the stabilizing frame 41 is provided with a sliding groove 42 for the sliding block 53 to slide.

[0059] The movable rod 63 moves upward and rotates, driving the second fixed rod 51 to follow the movement. The second fixed rod 51 rotates along the inner wall of the stabilizing frame 41 through the slider 53. At the same time, the stabilizing frame 41 moves upward along the guide rod 66. The stability of the upward movement and rotation of the clamping assembly 5 can be improved by the stabilizing assembly 4 and the guide rod 66.

[0060] The working principle and use process of the present invention:

[0061] The first connecting plate 32 is pulled to move the two first baffles 34 away from the first fixed plate 31, and at the same time, the first connecting rod 33 and the first movable rod 37 move the first spring latch 36 out of the groove outside the first movable rod 37. After the first baffle 34 moves, the circular hole 35 is in an open state, and the wire 2 can be placed inside the circular hole 35. At the same time, the first baffle 34 is pushed to move in the opposite direction to form the circular hole 35 with the first fixed plate 31, and the first baffle 34 is fixed by the first spring latch 36 being engaged with the groove outside the first movable rod 37.

[0062] By pulling the second connecting plate 57, the two second baffles 58 move toward the outer end along the guide groove 55, and at the same time, the second spring latch 513 is disengaged from the circular groove outside the second movable rod 512. When the second baffle 58 is away from the second fixed rod 51, the limiting hole is in an open state, and the upper end of the wire 2 can be placed in the limiting hole, and the second baffle 58 and the second fixed rod 51 are pushed to form the limiting hole, and the second spring latch 513 is engaged in the circular groove to fix the second baffle 58;

[0063] The wire 2 is fixed by the limiting assembly 3 and the clamping assembly 5. Since the protrusion 62 is engaged in the spiral groove 65 and is located at the upper end of the spiral groove 65, the movable rod 63 is pulled upward to cooperate with the protrusion 62 and the spiral groove 65, so that the movable rod 63 is rotated and moved upward and drives the second fixing rod 51 to rotate. Since the two wires 2 are sleeved in the two through holes on the second fixing rod 51, the lower ends of the two wires 2 are limited by the limiting assembly 3. The two wires 2 are twisted together by rotating the second fixing rod 51 upward, so that the two wires 2 are approximately twisted. The two wires 2 can be welded with the help of welding equipment, thereby avoiding manual knob rotation and preventing the wire from pricking the hand. The welding by turning the knobs of the two wires 2 can improve the stability of the motor coil welding.

[0064] The movable rod 63 moves upward and rotates to drive the second fixed rod 51 to follow the movement. The second fixed rod 51 rotates along the inner wall of the stabilizing frame 41 through the slider 53. At the same time, the stabilizing frame 41 moves upward along the guide rod 66. The stability of the upward movement and rotation of the clamping assembly 5 can be improved through the stabilizing assembly 4 and the guide rod 66.

[0065] Since the wire 2 is composed of multiple winding copper wires, the first roller 54 and the second roller 56 squeeze the wire 2 during the upward movement of the second fixing rod 51, so that the multiple copper wires gather toward the middle. The winding is more stable and neat during the process of passing through the clamping knob, which can improve the welding quality.
