[0044] The rack 1 provides mounting support for the up-down movement driving mechanism 3, and the up-down movement driving mechanism 3 can be a hydraulic cylinder or a pneumatic cylinder. The linear motion guide mechanism 101 provides guidance for the up-down movement of the mounting seat 2, and a slide rail and slide sleeve structure is preferably adopted. The mounting seat 2 provides mounting support for the main positioning shaft 4, the wire block 5, the wire driving mechanism, the winding mechanism 9 and the winding driving mechanism. During operation, the clamping mechanism clamps the rectifier, the up-down movement driving mechanism 3 drives the mounting seat 2 to move downward, the main positioning shaft 4 is vertically inserted into the positioning hole at the center of the rectifier for machining positioning. The wire driving mechanism drives the wire block 5 to move in along the radial direction of the rectifier, and the wire block 5 inclines the vertical stator lead wire towards the center of the rectifier. After the wire driving mechanism drives the wire block 5 to move out along the radial direction of the rectifier, the up-down movement driving mechanism 3 drives the mounting seat 2 to further press down, so that the winding mechanism 9 is inserted into the winding slot of the rectifier. The winding driving mechanism drives the winding mechanism 9 to rotate in the clockwise direction around the axial direction of the winding slot of the rectifier, and the inclined stator lead wire is pressed into the winding slot of the rectifier, so as to ensure that the stator lead wire contacts the terminal lug in the winding slot of the rectifier. Finally, the up-down movement driving mechanism 3 drives the mounting seat 2 to move upward for resetting.

[0045] Preferably, the mounting base 2 comprises an upper support base 201 and a lower support base 202, the upper support base 201 and the lower support base 202 are connected through a telescopic mechanism 203, the telescopic mechanism 203 is elongated or shortened along the vertical direction; the upper support base 201 is installed on the rack 1 through a linear motion guide mechanism 101; the main positioning shaft 4, the wire winding driving mechanism and the wire winding mechanism 9 are installed on the upper support base 201, and the other wire driving mechanism and the other wire block 5 are installed on the lower support base 202. The upper support base 201 provides mounting support for the main positioning shaft 4, the wire winding driving mechanism and the wire winding mechanism 9, and the lower support base 202 provides mounting support for the other wire driving mechanism and the other wire block 5. When the mounting base 2 is driven by the up-down motion driving mechanism 3 to move downward, the main positioning shaft 4 is vertically inserted into the positioning hole in the center of the rectifier for processing and positioning, and the telescopic mechanism 203 is elastically deformed to achieve buffering, so as to avoid damage to the rectifier due to excessive impact force.

[0046] The upper support base 201 can be a whole structure or a detachable structure. When the upper support base 201 is a detachable structure, it comprises a fixed base 2011 and a connecting base 2012, and the fixed base 2011 and the connecting base 2012 are detachably connected through bolts.

[0047] The telescopic mechanism 203 has various embodiments, such as a rubber pad. Preferably, the telescopic mechanism 203 comprises a plurality of vertical sleeves and a spring sleeved and installed outside the plurality of sleeves; the upper end of the plurality of sleeves is connected with the upper support base 201, and the lower end is connected with the lower support base 202. Specifically, the upper end of the plurality of sleeves is connected with the connecting base 2012.

[0048] Specifically, the wire winding mechanism 9 comprises a wire slot positioning column 901 and a wire winding pressing sleeve 902; the wire slot positioning column 901 is vertically installed through the upper support base 201, the wire winding pressing sleeve 902 is fixedly sleeved outside the wire slot positioning column 901, the lower end of the wire winding pressing sleeve 902 is located above the lower end of the wire slot positioning column 901, and the lower end face of the wire winding pressing sleeve 902 serves as the pressing surface; the wire winding driving mechanism is in transmission connection with the wire slot positioning column 901 and drives the wire winding pressing sleeve 902 to rotate along the clockwise direction around the axial direction of the wire slot positioning column 901. When the mounting base 2 is driven by the up-down motion driving mechanism 3 to move downward, the main positioning shaft 4 is vertically inserted into the positioning hole in the wire winding slot of the rectifier for processing and positioning, and the wire slot positioning column 901 is inserted into the positioning hole in the wire winding slot of the rectifier for positioning.

[0050] Preferably, the lower end of the winding pressing sleeve 902 is provided with an opening downward notch 9021, the side wall of the notch 9021 is smoothly transitioned with the lower end surface of the winding pressing sleeve 902. The smoothly transitioned part first contacts the inclined stator lead-out wire root, and then gradually presses the inclined stator lead-out wire into the rectifier winding slot through the lower end surface of the winding pressing sleeve 902, so that the stress on the plastic shell in the rectifier winding slot is more uniform, which can effectively avoid the plastic shell in the rectifier winding slot being crushed by the winding pressing sleeve 902.

[0051] In order to further improve the positioning accuracy, preferably, the winding mechanism 9 further comprises a positioning sleeve 903, the positioning sleeve 903 is connected with the upper support seat 201 and sleeved outside the winding pressing sleeve 902, the lower end of the positioning sleeve 903 extends downward and is provided with a positioning section 9031 matched with the opening on the rectifier winding slot; the lower end of the positioning section 9031 is located between the lower end of the winding pressing sleeve 902 and the lower end of the slot positioning column 901. The rectifier winding slot is provided with an opening away from the center of the rectifier, the positioning section 9031 is matched with the opening, which is used to close the opening of the rectifier winding slot and form an annular groove for limiting the pressing and installation of the stator lead-out wire. When the upper and lower movement driving mechanism 3 drives the mounting seat 2 to further press down, the winding mechanism 9 is inserted into the rectifier winding slot, and the positioning sleeve 903 is also pressed down and closes the opening of the rectifier winding slot through the positioning section 9031. The upper support seat 201 provides connection and installation support for the positioning sleeve 903, specifically, the connecting seat 2012 provides connection and installation support for the positioning sleeve 903. The positioning sleeve 903 and the winding pressing sleeve 902 have relative rotation, when the winding driving mechanism drives the winding pressing sleeve 902 to rotate, the positioning sleeve 903 remains stationary.

[0052] The positioning sleeve 903 can be fixedly connected with the upper support base 201. Since the sizes of different rectifier winding grooves and the tolerances after the assembly of the tool are different, in order to avoid that the positioning sleeve 903 presses and damages the plastic shell in the rectifier winding groove when it is pressed downward, preferably, a restoring mechanism is further included, the restoring mechanism includes a restoring driving mechanism 10 and a restoring ring 11; the restoring ring 11 is coaxially arranged with the main positioning shaft 4; the restoring ring 11 is slidingly installed on the upper support base 201; the restoring driving mechanism 10 is installed on the upper support base 201 and drives the restoring ring 11 to rotate around its own axis; an installation groove 1101 is formed in the inner side of the restoring ring 11, a protrusion 904 is arranged on the positioning sleeve 903, the protrusion 904 is movably installed in the installation groove 1101 and has a restoring adjustment space.

[0053] Before the upper and lower movement driving mechanism 3 drives the mounting seat 2 to further press downward and the positioning sleeve 903 is pressed downward, the restoring driving mechanism 10 is first driven to rotate around the main positioning shaft 4 in a direction away from the positioning reference by a certain angle. After the upper and lower movement driving mechanism 3 drives the mounting seat 2 to further press downward, the winding mechanism 9 is inserted into the rectifier winding groove, and the positioning sleeve 903 is pressed downward, the restoring driving mechanism 10 drives the restoring ring 11 to rotate in the opposite direction, thereby driving the positioning sleeve 903 to rotate around the main positioning shaft 4 in a direction close to the positioning reference by a certain angle, so that the positioning section 9031 closes the opening on the rectifier. The positioning reference refers to the position of one of the side walls of the opening of the rectifier. By making the side wall abut against the positioning section 9031, the positioning section 9031 can just close the opening on the rectifier.
