[0035] Please refer to Figures 1-4 The embodiment provides a novel motor stator busbar welding tool, which comprises:

[0036] The first tightening disc is placed in the inner periphery of the flat copper wire motor stator, and two or more first guide grooves are formed on the first tightening disc; the first busbar on the flat copper wire motor stator is positioned and clamped by the first guide grooves on the first tightening disc and the first clamping tool;

[0037] The second tightening disc is placed in the outer periphery of the flat copper wire motor stator, and two or more second guide grooves are formed on the second tightening disc; the second busbar on the flat copper wire motor stator is positioned and clamped by the second guide grooves on the second tightening disc and the second clamping tool;

[0038] The first clamping tool is in sliding connection with the first guide groove, and is used for clamping the first busbar on the flat copper wire motor stator to ensure the stability and positional accuracy of the first busbar during welding;

[0039] The second clamping tool is in sliding connection with the second guide groove and is used for clamping the second bus bar on the stator of the flat copper wire motor to ensure the stability and position accuracy of the bus bar during welding.

[0040] The bearing disc is placed on the stator of the flat copper wire motor, the second tightening disc is located on the groove body of the bearing disc, and the first tightening disc is located at the through hole of the bearing disc; the bearing disc is provided with a fixed cover, more than two first clamping grooves and second clamping grooves are formed in the fixed cover, the push block of the first clamping tool is arranged in the corresponding first clamping groove, the push block of the second clamping tool is arranged in the corresponding second clamping groove, and the threaded column in the middle of the first tightening disc is in rotational connection with the threaded groove on the fixed cover. The bearing disc and the fixed cover provide a stable support platform for the first tightening disc and the second tightening disc, so that the two can correctly cooperate with and clamp the bus bar on the stator of the motor.

[0041] As shown in Figure 5 The first clamping tool and the second clamping tool are the same in structure and each include a locking sliding block, a connecting pin and a push block. The locking sliding block is provided with a strip-shaped through hole, the push block is symmetrically provided with a fixing hole, and the connecting pin is arranged in the strip-shaped through hole, the fixing hole and the guide groove. The locking sliding block includes a clamping block, an adjusting block and a limiting rod which are connected in sequence. The clamping block is used for directly clamping the bus bar on the stator of the flat copper wire motor to ensure the stability and position accuracy of the bus bar during welding. The adjusting block is provided with a strip-shaped through hole and is used for cooperating with the connecting pin to realize the sliding adjustment of the locking sliding block. The limiting rod is used for limiting the sliding range of the locking sliding block to prevent the locking sliding block from excessively sliding and being separated from the push block cavity.

[0042] As a preferred embodiment provided in the embodiment, the first tightening disc is provided with a first rotating handle and the two are an integral structure, the second tightening disc is provided with a second rotating handle and the two are an integral structure, and one end of the first rotating handle and the second rotating handle is arranged to pass through an arc-shaped adjusting hole on the fixed cover. The arc-shaped adjusting hole provides a certain rotating range. In this way, the operator can adjust the position of the tightening disc and the clamping force by rotating the handle. The side wall of the bearing disc is provided with a plurality of ball clamping grooves. When the tightening disc is rotated to the locking position by the rotating handle, the ball protrusion falls into the ball clamping groove, thereby locking the position of the tightening disc and preventing the tightening disc from being accidentally rotated or moved, so as to ensure the stability and reliability of the tightening disc in the locked state.

[0043] As the preferred embodiment provided by the present embodiment, the arc-shaped adjusting hole is provided with a safety operation mark; when the rotating handle is in the red position, the push rod is in its original position; then, by rotating the handle to the yellow position, the push rod will move forward until it moves to the lower surface of the installation busbar position, playing a supporting role. At this time, the operator can place the busbar at the corresponding position of the flat copper wire motor stator; then, rotate the handle to the green position again, the push rod will further push the busbar to the flat copper wire motor stator, making it tightly clamp the flat copper wire motor stator and the busbar. In this way, the welding gap will become more rigorous, thereby ensuring the improvement of the welding strength.

[0044] As the preferred embodiment provided by the present embodiment, the first guide groove and the second guide groove are spiral long tracks close to the circular edge from the center of the circle, which realize the radial sliding of the first clamping tool and the second clamping tool. This radial adjustment enables the clamping tool to gradually approach or move away from the busbar on the flat copper wire motor stator, thereby realizing the precise tightening or loosening of the busbar. Precise radial adjustment and tightening force control help to improve the tightness of the welding gap and the welding strength.

[0045] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand: they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
