[0045] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0046] like Figure 1-2As shown, a motor stator busbar welding tool comprises:

[0047] A mounting ring 1, which is suitable for being arranged on a motor stator 10, and is provided with an upper annular groove 11 and a lower annular groove 12;

[0048] The rotating ring 2 is provided with a plurality of arc-shaped waist-shaped holes 21 along the circumferential direction, and the rotating ring 2 is rotatably installed in the lower annular groove 12 of the mounting ring 1;

[0049] An upper pressure ring 3, a plurality of linear grooves 31 are formed on the lower surface of the upper pressure ring 3 along the circumferential direction, the upper pressure ring 3 is installed in the upper annular groove 11 of the mounting ring 1, and a mounting connecting plate 32 is provided on the upper pressure ring 3;

[0050] A plurality of outer clamping jaw assemblies 4, the outer clamping jaw assemblies 4 are slidably mounted in the linear grooves 31 of the corresponding upper pressure rings 3, and a connecting pin is hinged on the outer clamping jaw assemblies 4, and the connecting pin passes through the arc-shaped waist-shaped holes 21 of the corresponding rotating rings 2;

[0051] The outer circumference of the mounting ring 1 is provided with a plurality of notches arranged at intervals corresponding to the linear movement positions of the outer clamping jaw assembly 4;

[0052] A sliding support plate 5, wherein a sliding waist-shaped hole 51 is provided on the sliding support plate 5, and the sliding support plate 5 is suitable for being detachably and slidably mounted on the mounting connecting plate 32 of the upper pressure ring 3 by passing bolts through the sliding waist-shaped hole 51;

[0053] A clamping mechanism 6, the clamping mechanism 6 is mounted on the mounting connecting plate 32 of the upper pressing ring 3, and the clamping mechanism 6 is adapted to be actuated to clamp the busbar 100 on the sliding support plate 5;

[0054] The rotation control assembly 7 is connected to the rotating ring 2. The rotation control assembly 7 is suitable for driving the rotating ring 2 to rotate so as to radially move the outer clamp assembly 4 along the extension direction of the linear groove 31 of the upper pressure ring 3, and push the corresponding motor stator 10 and the bus 100 to clamp the wire ends.

[0055] In this embodiment, if Figure 1-2As shown, first, the mounting ring 1 is set on the motor stator 10 to ensure that the outer clamping jaw assembly 4 is accurately aligned with the wire ends of the motor stator 10. Subsequently, the operator slides the sliding support plate 5 to correctly place the bus 100 thereon. By actuating the clamping mechanism 6, the bus 100 is firmly clamped on the sliding support plate 5. Next, the rotation control assembly 7 is controlled to drive the rotating ring 2 to rotate. This action drives the outer clamping jaw assembly 4 to move along the linear groove 31 of the upper pressure ring 3 through the connecting pin and the arc-shaped waist hole 21 on the rotating ring 2, thereby pushing the wire ends of the motor stator 10 to be tightly clamped with the clamped wire ends of the bus 100. The entire process not only ensures the precise alignment of the welding points, but also greatly simplifies the operation process and significantly reduces the difficulty of operation.

[0056] During the disassembly process, the operator drives the rotating ring 2 to rotate in the opposite direction by rotating the control assembly 7, thereby releasing the outer clamping jaw assembly 4 and thereby releasing the clamping force on the wire ends of the motor stator 10. Subsequently, the clamping mechanism 6 is actuated again to release the clamping force on the busbar 100, and then the sliding support plate 5 is slid to completely release the support for the busbar 100. Through these steps, the motor stator busbar welding tooling can be easily and completely removed, and the entire disassembly process is both simple and efficient.

[0057] In this embodiment, the clamping mechanism 6 can use a quick clamp, which is a prior art and will not be described in detail in this embodiment.

[0058] Specifically, Figure 1-2 As shown, the outer clamping jaw assembly 4 can be the following structure, including:

[0059] The outer shell 41 is slidably mounted in the linear groove 31 of the corresponding upper pressure ring 3;

[0060] A clamping jaw 42, the clamping jaw 42 is slidably mounted in the outer shell 41;

[0061] The connecting pin passes through the outer shell 41 and the clamping claw 42 , and extends through the arc-shaped waist-shaped hole 21 on the rotating ring 2 that matches therewith.

[0062] Specifically, Figure 1-2 As shown, a waist-shaped through hole 421 is provided on the clamping jaw 42;

[0063] The outer shell 41 is provided with a circular through hole 411 which matches with the waist-shaped through hole 421;

[0064] The connecting pin passes through the waist-shaped through hole 421 and the circular through hole 411;

[0065] The outer shell 41 further includes an elastic member 43 , which is disposed in the outer shell 41 . One end of the elastic member 43 abuts against the end surface of the clamping jaw 42 , and the other end abuts against the inner wall of the outer shell 41 .

[0066] In this embodiment, if Figure 1-2 As shown, the function of the outer clamping jaw assembly 4 is to clamp the wire ends of the motor stator 10 so that they are in close contact with the wire ends of the busbar 100, which is convenient for subsequent welding operations.

[0067] When in use, the rotation control assembly 7 drives the rotating ring 2 to rotate, so that the outer clamping jaw assembly 4 moves radially along the linear groove 31 of the upper pressing ring 3. The outer shell 41 slides in the linear groove 31 of the upper pressing ring 3, and the clamping jaw 42 slides in the outer shell 41. The connecting pin passes through the outer shell 41, the clamping jaw 42 and the arc waist hole 21 of the rotating ring 2, so that they form an integral motion mechanism.

[0068] When the rotating ring 2 rotates from the outside to the inside of the arc-shaped waist hole 21, the outer clamping jaw assembly 4 is driven to move inward, so that the clamping jaws 42 clamp the stator wire ends inward. On the contrary, when the rotating ring 2 rotates in the opposite direction, the outer clamping jaw assembly 4 moves outward, so that the clamping jaws 42 open outward and release the wire ends of the motor stator 10.

[0069] The elastic member 43 can be a compression spring or the like as required.

[0070] Specifically, Figure 1-2 As shown, the motor stator busbar welding tool further includes two handles 8 , which are mounted on the outer surface of the mounting ring 1 .

[0071] In this embodiment, if Figure 1-2 As shown, the function of the handle 8 is to facilitate the operator to lift and move the entire motor stator busbar welding tool. The handle 8 is installed on the outer surface of the mounting ring 1, and the mounting ring 1 is the main frame structure of the entire tool. Through the handle 8, the operator can firmly grasp the motor stator busbar welding tool, move it or adjust its position and angle. The design of using two handles 8 fully considers the volume and weight of the tool. It can disperse the force and facilitate operation.

[0072] In some embodiments, the number of handles 8 is not limited to two and can be set according to specific needs.

[0073] Specifically, Figure 1-2 As shown, the rotation control assembly 7 includes a control handle 71 and a connecting block 72;

[0074] The rotating ring 2 is provided with a connection block fixing hole 22, and the connection block 72 is suitable for being fixed on the rotating ring 2 by passing a bolt through the connection block fixing hole 22;

[0075] The control handle 71 is mounted on the connection block 72 .

[0076] In this embodiment, if Figure 1-2As shown, the function of the rotation control assembly 7 is to control the rotation of the rotating ring 2 by manpower, thereby driving the outer clamping jaw assembly 4 to perform radial movement.

[0077] The connecting block 72 connects the control handle 71 and the rotating ring 2. A connecting block mounting groove is provided on the rotating ring 2, and two bolt mounting holes are also provided on the connecting block mounting groove;

[0078] The connecting block 72 is fixed in the connecting block fixing hole 22 on the rotating ring 2 by means of bolts, so that they can rotate synchronously as a whole.

[0079] The control handle 71 is mounted on the connecting block 72, and the operator can conveniently grasp and rotate the control handle 71. When the control handle 71 is rotated, the connecting block 72 and the rotating ring 2 will also rotate together.

[0080] Specifically, Figure 1-2 As shown, the connecting block 72 is also provided with an indication mark 721;

[0081] A circumferential movement position mark 321 corresponding to the indicator mark 721 is provided on the upper surface of the upper pressure ring 3 when the rotating ring 2 and the connecting block 72 on the rotating ring 2 rotate to the limit position.

[0082] In this embodiment, if Figure 1-2 As shown, the indicator mark 721 and the circumferential movement position mark 321 are used to provide visual instructions to the operator to avoid structural damage caused by excessive rotation.

[0083] When the rotation control assembly 7 drives the rotating ring 2 to rotate, the indicator mark 721 on the connecting block 72 will also rotate accordingly. The circumferential movement position mark 321 on the upper pressing ring 3 indicates the limit rotation position of the rotating ring 2 and the connecting block 72.

[0084] The operator can always observe the relative position of the indicator mark 721 and the circumferential movement position mark 321. Once the indicator mark 721 approaches or reaches the movement position mark 321, the rotation can be stopped to avoid excessive rotation causing structural interference or damage.

[0085] The indicator mark 721 may adopt a distinct color or pattern to improve recognition.

[0086] Specifically, Figure 1-2 As shown, the sliding support plate 5 is provided with a pair of sliding waist-shaped holes 51 .

[0087] In this embodiment, if Figure 1-2 As shown, a pair of sliding waist-shaped holes 51 are provided on the sliding support plate 5, the purpose of which is to achieve more stable sliding through two parallel sliding waist-shaped holes 51, and reduce shaking or displacement of the sliding support plate 5 when subjected to external force.

[0088] A pair of sliding waist-shaped holes 51 correspond to two fixing holes on the mounting connecting plate 32 of the upper pressing ring 3. By inserting fasteners such as bolts into these waist-shaped holes and the fixing holes, the sliding support plate 5 can be firmly fixed on the upper pressing ring 3.

[0089] Specifically, Figure 1-2 As shown, the motor stator busbar welding tool further includes a clamping block 61, which is mounted on the clamping mechanism 6, and is provided with avoidance slots corresponding to the busbar contacts of the busbar 100;

[0090] In this embodiment, if Figure 1-2 As shown, the function of the pressing block 61 is to firmly press the busbar 100 onto the wire end of the motor stator 100 to prepare for subsequent welding.

[0091] The pressing block 61 is installed on the pressing mechanism 6. When the pressing mechanism 6 drives the pressing block 61 to descend, the pressing block 61 will press the busbar 100 onto the stator wire head.

[0092] In order to prevent the clamping block 61 from interfering with or crushing the bus contacts of the bus 100, avoidance slots corresponding to the bus contacts are provided on the clamping block 61. The position, size and shape of these avoidance slots correspond to the bus contacts of the bus 100 to completely avoid the area of ​​the bus contacts. The extrusion surface of the clamping block 61 can be made of plastic, rubber or other soft materials as a cushion layer to increase the friction during compression and prevent the bus 100 from being displaced. At the same time, these materials can also prevent scratches caused by direct metal contact.

[0093] Specifically, Figure 1-2 As shown, the motor stator busbar welding tool further includes two lifting handles 9, and the lifting handles 9 are detachably mounted on the upper surface of the pressing block 61 through connecting pieces.

[0094] In this embodiment, if Figure 1-2 As shown, the function of the lifting handle 9 is to provide a convenient handle for the operator to lift or move the pressing block 61. The lifting handle 9 is detachably mounted on the upper surface of the pressing block 61 through a connecting piece. This detachable design allows the lifting handle 9 to be installed or removed at any time as needed, avoiding its presence affecting normal operation. When the pressing block 61 needs to be displaced or adjusted, the operator can grasp the lifting handle 9 and apply force to drive the pressing block 61 to move. This is more convenient and safer than directly grasping the pressing block 61 itself.

[0095] In some embodiments, the number of lifting handles 9 is not limited to two and can be set according to specific needs.

[0096] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
