[0045] In order to make the purpose, technical scheme and advantages of the present application more clear, the following will make further detailed description to the embodiment of the present application in combination with the drawings.

[0046] Although the present application can be easily embodied as different forms of embodiments, only some specific embodiments are shown in the drawings and will be described in detail in the present specification, and it can be understood that the present specification should be regarded as the exemplary description of the principle of the present application, and is not intended to limit the present application to that described herein.

Thus, the described combinations are not intended to be limiting unless otherwise noted.

[0048] In the embodiments shown in the drawings, the indications of direction, such as up, down, left, right, front, and back, are used to explain the structure and movement of various elements of the application are not absolute but relative. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the positions of these elements change, the indications of direction also change accordingly.

[0049] Please refer to Figures 1 to 3 , Figure 1 is a structural schematic view of a stator three-phase outgoing line end welding device 10 provided by the embodiment of the application, Figure 2 Figure 1 is an assembly structure schematic view of the stator three-phase outgoing line end welding device 10 and the stator 20 shown in the drawings, Figure 3 is Figure 1 is an exploded structural schematic view of the stator three-phase outgoing line end welding device 10 shown in the drawings, the stator three-phase outgoing line end welding device 10 can include a mounting base 11, an adjusting assembly 12, and a clamping assembly 13.

[0050] The mounting base 11 can be mounted at the end of the stator 20, and the mounting base 11 can be annular to be able to be sleeved and clamped at the end of the stator 20.

[0051] Please refer to Figure 4 and Figure 5 , Figure 4 is Figure 1 is a structural schematic view of another perspective of the stator three-phase outgoing line end welding device 10 shown in the drawings, Figure 5 is Figure 4 is an exploded structural schematic view of the stator three-phase outgoing line end welding device 10 shown in the drawings, the adjusting assembly 12 can include an adjusting support 121 and a connecting block 122, the adjusting support 121 is mounted on the mounting base 11, the connecting block 122 is arranged on the adjusting support 121, the connecting block 122 is adapted to move relative to the adjusting support 121 along the radial direction of the stator 20 and the circumferential direction of the stator 20, and rotate relative to the adjusting support 121 around the direction parallel to the axial direction of the stator 20. The clamping assembly is detachably connected with the connecting block, and the clamping assembly is used to clamp the copper bar.

[0052] The clamping assembly 13 can be connected to the connecting block 122 away from the adjusting support 121, and the clamping assembly 13 is used to clamp the copper bar 30. The copper bar 30 is a component connected to the three-phase outgoing terminals of the stator, and is usually made of red copper or other materials with good electrical conductivity, and is used to realize the connection of the three-phase circuit inside the motor.

[0053] In this way, by connecting the clamping assembly 13 to the connecting block 122, the clamping assembly 13 can be moved in multiple directions (for example, the multiple directions include the radial direction, the circumferential direction and the axial direction of the stator) by the connecting block 122, so that the copper bar 30 is moved in multiple directions by the clamping assembly 13, so as to accurately position the copper bar 30 according to the position of the three-phase outgoing terminals of the stator, and ensure the accurate alignment of the copper bar 30 and the three-phase outgoing terminals of the stator, which can improve the positioning accuracy of the copper bar 30, thereby improving the welding quality between the three-phase outgoing terminals of the stator and the copper bar 30.

[0054] Optionally, the adjusting support 121 has a first limiting groove c1 extending in the radial direction of the stator 20, and the adjusting support 121 can be installed on the side of the installation base 11 away from the ground. The connecting block 122 is arranged in the first limiting groove c1 and is in clearance fit with the first limiting groove c1 in the direction parallel to the circumferential direction of the stator 20. The connecting block 122 is movably installed in the first limiting groove c1, so that the connecting block 122 can slide in the first limiting groove c1 along the extension direction of the first limiting groove c1 (i.e., the radial direction of the stator 20).

[0055] Please continue to refer to Figure 6 , Figure 6 is Figure 1 another perspective view of the stator three-phase outgoing terminal welding device 10 shown in FIG. 6, and in the direction parallel to the circumferential direction of the stator 20, the connecting block 122 has a moving gap x1 between the connecting block 122 and the groove wall of the first limiting groove c1. In this way, by the clearance fit between the connecting block 122 and the first limiting groove c1, the connecting block 122 can move in the first limiting groove c1 along the circumferential direction of the stator 20, or the connecting block 122 can rotate in the first limiting groove c1 about a direction perpendicular to the groove bottom of the first limiting groove c1, or the connecting block 122 can move in the first limiting groove c1 along the circumferential direction of the stator 20 while the connecting block 122 can rotate in the first limiting groove c1 about a target axis, and the extension direction of the target axis can be perpendicular to the direction perpendicular to the groove bottom of the first limiting groove c1, and the direction perpendicular to the groove bottom of the first limiting groove c1 can be parallel to the axial direction of the stator 20. For example, in the direction parallel to the circumferential direction of the stator 20, the connecting block 122 has a moving gap x1 between the two sides of the connecting block 122 and the two groove walls of the first limiting groove c1, and the width of the moving gap x1 can be 1 mm to 3 mm, for example, the width of the moving gap x1 between the connecting block 122 and the groove wall of the first limiting groove c1 is 1 mm, 1.5 mm, 2 mm or 2.3 mm.

[0056] Since the connecting block 122 can move in multiple directions in the first limiting slot c1, for example, the connecting block 122 can slide along the extension direction of the first limiting slot c1, that is, can slide along the radial direction of the stator 20, and can slide along the axial direction of the stator 20, and can also rotate along the axial direction of the stator 20. And since the movement gap x1 between the connecting block 122 and the slot wall of the first limiting slot c1 is small in the direction parallel to the circumferential direction of the stator 20, the maximum displacement stroke of the connecting block 122 along the circumferential direction of the stator 20, and the maximum rotation stroke around the target axis, are all smaller than the maximum displacement stroke of the connecting block 122 along the radial direction of the stator 20. Therefore, through the connecting block 122 and the clamping assembly 13, the position of the copper bar 30 along the radial direction of the stator 20 can be adjusted, the position of the copper bar 30 along the circumferential direction of the stator 20 can be finely adjusted, and the posture of the copper bar 30 can be finely adjusted.

[0057] It should be noted that the radial direction, the axial direction and the circumferential direction of the stator 20 in the embodiments of the utility model include the strict radial direction, the strict axial direction and the strict circumferential direction, and the directions substantially parallel to the radial direction, the axial direction and the circumferential direction, for example, the "substantially" can represent within one or more deviation ranges, and if not particularly specified, can represent within the deviation range of the direction deviation angle of 5° to 15°.

[0058] Through the above design, the three-phase outgoing line end welding device provided by the embodiment of the utility model has the adjusting assembly 12, the clamping assembly 13 and the mounting base 11, wherein the adjusting assembly 12 comprises the adjusting support 121 and the connecting block 122, the first limiting groove c1 extending along the radial direction of the stator 20 is formed on the adjusting support 121, the connecting block 122 is movably installed in the first limiting groove c1, and in the direction parallel to the circumferential direction of the stator 20, the connecting block 122 has a moving gap x1 between the connecting block 122 and the groove wall of the first limiting groove c1, in this way, the connecting block 122 can slide in the first limiting groove c1 along the extension direction of the first limiting groove c1 (i.e. the radial direction of the stator 20), and through the cooperation of the moving gap x1 between the connecting block 122 and the first limiting groove c1, the connecting block 122 can slightly move or rotate in multiple directions in the first limiting groove c1. Therefore, by connecting the clamping assembly 13 to the connecting block 122, the copper bar 30 clamped by the clamping assembly 13 and the clamping assembly 13 can be driven to move in multiple directions by the connecting block 122, so as to accurately position the copper bar 30 according to the position of the three-phase outgoing line end of the stator, ensure the accurate alignment of the copper bar 30 and the three-phase outgoing line end of the stator, improve the positioning accuracy of the copper bar 30, and thus improve the welding quality between the three-phase outgoing line end of the stator and the copper bar 30. The problem that the positioning accuracy of the copper bar 30 is poor in the related art, which leads to low welding quality of the three-phase outgoing line end of the stator, can be solved.

[0059] In an exemplary embodiment, the number of the connecting blocks 122 in the adjusting assembly 12 can be multiple, the number of the first limiting grooves c1 on the mounting base 11 can also be multiple, the multiple connecting blocks 122 are correspondingly installed in the multiple first limiting grooves c1, and the number of the clamping assemblies 13 can also be multiple, the multiple clamping assemblies 13 are correspondingly connected with the multiple connecting blocks 122. For example, the number of the connecting blocks 122, the number of the first limiting grooves c1 and the number of the clamping assemblies 13 can all be three, and the connecting blocks 122, the first limiting grooves c1 and the clamping assemblies 13 can all be arranged at intervals along the extension direction of the adjusting support 121, and correspond to the outgoing line terminals of the U-phase, W-phase and V-phase outgoing line ends on the stator 20 of the motor respectively, so as to be able to position and weld the three-phase outgoing line end respectively, thereby improving the positioning accuracy.

[0060] Please refer to Figure 4 and Figure 5 In an alternative embodiment, the adjusting assembly 12 can further comprise a first locking piece 123, the groove bottom of the first limiting groove c1 on the adjusting support 121 has a first mounting hole k1, and the connecting block 122 has a first strip-shaped through hole k2 extending along the radial direction of the stator 20; the connecting block 122 is connected with the adjusting support 121 by penetrating the first strip-shaped through hole k2 and the first mounting hole k1 through the first locking piece 123, and is adapted to rotate around the axis of the first locking piece 123 to adjust the direction.

[0061] The first end of the first locking piece 123 is arranged in the first strip-shaped through hole k2 and the first mounting hole k1, is connected with the adjusting support 121 through the first mounting through hole, and is movably connected with the first fixing piece through the first strip-shaped through hole k2. The second end of the first locking piece 123 is located outside the first strip-shaped through hole k2 and can abut against the connecting block 122.

[0062] The first locking piece 123 can include a butterfly bolt, the first locking piece 123 can include a first screw rod and a first head portion fixedly connected, the first screw rod of the first locking piece 123 can be located at the first end, and the first head portion can be located at the second end. The first screw rod is arranged in the first strip-shaped through hole k2 and the first mounting hole k1. The inner wall of the first mounting hole k1 can have a thread, so that the first screw rod can be screwed with the adjusting support 121 through the first mounting hole k1, and the connecting block 122 is pressed against the adjusting support 121 through the first head portion, so as to lock the connecting block 122.

[0063] The extension direction of the first strip-shaped hole can be parallel to the extension direction of the first limiting groove c1, and the width of the first strip-shaped hole in the circumferential direction of the stator 20 is greater than the diameter of the first screw rod. In this way, when the position of the connecting block 122 is adjusted, the first locking piece 123 can be rotated to release the locking of the connecting block 122, so that the connecting block 122 is in a floating state. Since the width of the first strip-shaped hole in the circumferential direction of the stator 20 is greater than the diameter of the first screw rod, the first locking piece 123 does not need to be completely pulled out of the first strip-shaped through hole k2 and the first mounting hole k1, and the connecting block 122 can be adjusted in multiple directions, so as to drive the copper bar 30 and the three-phase outlet end of the stator on the clamping assembly 13 to be aligned.

One end of the rotating support 1212 is rotatably connected to the arc-shaped support 1211, and the other end of the rotating support 1212 is detachably connected to the arc-shaped support 1211. The first limiting slot c1 is located on a side of the rotating support 1212 that faces away from the arc-shaped support 1211. That is, the connecting block 122 can be mounted on the rotating support 1212, so that the clamping assembly 13 is mounted on the rotating support 1212 through the connecting block 122.

[0065] The rotating support 1212 can be arc-shaped and have opposite first and second ends. The first end of the rotating support 1212 is rotatably connected to the arc-shaped support 1211, and the second end of the rotating support 1212 is detachably connected to the arc-shaped support 1211. After the copper bars 30 and the three-phase outgoing terminals of the stator are welded, the second end of the rotating support 1212 can be separated from the arc-shaped support 1211, and the rotating support 1212 can be rotated about the first end to separate the clamping assembly 13 on the rotating support 1212 from the welded copper bars 30. Then, the three-phase outgoing terminal welding device 10 can be detached from the stator 20, so that the welded copper bars 30 are not affected when the three-phase outgoing terminal welding device 10 is detached.

In this way, by moving the arc-shaped support 1211 along the circumferential direction of the stator 20, the rotating support 1212, the connecting block 122 and the clamping assembly 13 located on the rotating support 1212 can be moved along the circumferential direction, so as to adjust the position of the copper bar 30 along the circumferential direction of the stator 20, so as to compensate the distance between the copper bar 30 and the three-phase outgoing line terminal, and accurately position the copper bar 30 and the three-phase outgoing line terminal.

The width of the arc-shaped limiting slot c2 can be slightly larger than the diameter of the limiting column, so as to facilitate the relative displacement between the limiting column and the arc-shaped support 1211 in the arc-shaped limiting slot c2.

[0069] Please refer to Figure 7 and Figure 8 In an exemplary implementation, the adjusting support 121 can further include a second locking member 1218, and the arc-shaped support 1211 can further have an arc-shaped connecting through hole k3, and the mounting base 11 can have a second mounting hole k4 corresponding to the arc-shaped connecting through hole k3; the extending direction of the arc-shaped connecting through hole k3 is parallel to the extending direction of the arc-shaped limiting slot c2; two ends of the second locking member 1218 are arranged in the arc-shaped connecting through hole k3 and the second mounting hole k4 and connected to the mounting base 11, and the other two ends of the second locking member 1218 are located outside the arc-shaped connecting through hole k3 and abut against the arc-shaped support 1211.

[0076] The first end of the first arc-shaped clasp ring 111 and the first end of the second arc-shaped clasp ring 112 can be rotationally connected through the second rotation shaft 114, and the clamping piece 113 can include an elastic clamping structure.

[0077] For example, the first rotation shaft 1214 and the second rotation shaft 114 in the embodiment of the present application can each include a shaft shoulder bolt.

[0078] Please refer to Figure 9 and Figure 10In an alternative embodiment, the mounting base 11 further comprises an axial positioning member 115 and a circumferential positioning member 116.

[0080] In this way, the axial positioning member 115 and the circumferential positioning member 116 can improve the accuracy of the installation position of the stator three-phase outgoing line end welding device 10, thereby improving the positioning accuracy of the copper bar 30 and the three-phase outgoing line terminal.

[0081] In an exemplary embodiment, the process of welding the stator three-phase outgoing line end can include the following steps:

[0082] (1) Ensure that the three-phase outgoing line on the stator 20 and the three-phase outgoing line terminal at the end of the outgoing line are assembled, and obtain the copper bar 30, the welding equipment and the related tools.

[0083] (2) Determine the installation position of the stator three-phase outgoing line end welding device 10 by the axial positioning member 115 and the circumferential positioning member 116, and set the mounting base 11 of the stator three-phase outgoing line end welding device 10 on the end of the stator 20, and lock the clamping member 113.

Any one of the connecting blocks 122 can be finely adjusted in multiple directions. In this way, the adjusting assembly 12 can adjust the positions of the plurality of clamping assemblies and the copper bar 30 on the clamping assembly 13, thereby improving the positioning accuracy of the copper bar 30 and the three-phase outgoing line terminal.

[0085] (4) Use the welding equipment, such as a hot melt welding machine, to weld the copper bar 30 and the winding end.

[0086] (5) Separate the clamping assembly 13 from the copper bar 30, and rotate the rotating support 1212 to move the first end of the rotating support 1212 away from the stator 20, and remove the stator three-phase outlet terminal welding device 10 from the stator 20.
