[0028] The following is a detailed description of the positioning tool for assembling motor terminal blocks according to an embodiment of the utility model with reference to the accompanying drawings.

[0029] like Figure 1-Figure 3 As shown, the positioning tool for assembling motor terminals according to the embodiment of the utility model includes: a base 1, a support 2, a platform 3 and a force-applying component; the support 2 is arranged on the base 1, and two rollers 21 are arranged on the support 2 along the horizontal direction, and the two rollers 21 are used to support the iron core so that the terminals on the iron core are in a horizontal state. A limit block 32 and a stop bar 31 are arranged on the platform 3 along the central axis direction of the iron core, and the stop bar 31 is located on the side away from the iron core. The terminal is located on the platform 3, and the limit block 32 is used to limit the movement range of the terminal in the X direction, and the stop bar 31 is used to measure the position of the terminal in the Y direction. The force-applying component is arranged above the platform 3, and the force-applying component moves back and forth along the Z direction to cooperate with the platform 3 to extrude the terminal.

[0030] In this embodiment, the terminal is sleeved on the lead-out end of the coil, and the iron core is placed horizontally on two rollers 21, so that the terminal on the iron core is placed horizontally on the support 2. The position of the central axis of the iron core is limited by the two rollers 21 to avoid the terminal from shifting due to the rolling of the iron core. At this time, the position of the terminal is moved by measuring the stop bar 31 so that one end of the terminal is in close contact with the stop bar 31, thereby ensuring the height consistency of each terminal after stamping, and limiting the left and right directions of the terminal through the limit block 32, thereby avoiding the angle tilt caused by the terminal slipping during the process of flattening the terminal by the force-applying component, thereby ensuring the angle consistency of each terminal after stamping.

[0031] The roller 21 is rotatably connected to the support platform 2 so that the position of the iron core can be adjusted on the roller 21 .

[0032] In this embodiment, the roller 21 is connected to the support platform 2 by a bearing, and the iron core can be adjusted in angle by rotating on the roller 21 so that the connection terminal is located within the restricted area of ​​the limit block 32 .

[0033] The support platform 2 is slidably connected to the base 1 along the axial direction of the roller 21, so that after the iron core is placed, the connecting terminals on the iron core are sent between the platform 3 and the force-applying component.

[0034] In this embodiment, since the terminal blocks need to be placed between the platform 3 and the force-applying component, directly placing the iron core in a fixed position will cause the coil lead-out ends connected to the terminal blocks to be bent, which is not conducive to placing the terminal blocks between the platform 3 and the force-applying component. Through the movable support 2, after the iron core is placed, the iron core can be pushed close to the platform 3, so that the terminal blocks enter between the platform 3 and the force-applying component, thereby improving the convenience of placing the terminal blocks.

[0035] A first limiting ring 211 and a second limiting ring 212 are sleeved on the circumferential surface of the roller 21 . The first limiting ring 211 and the second limiting ring 212 are respectively arranged at two ends of the roller 21 to support the iron core and prevent the iron core from moving along the Y direction.

[0036] In this embodiment, the iron core is limited by the first limiting ring 211 and the second limiting ring 212 to prevent the iron core from shifting forward and backward during rotation, causing the connecting terminal to slide out from between the platform 3 and the force-applying assembly.

[0037] A guide groove is formed on the circumferential surface of the roller 21, and the guide groove includes a main rod 213 and a plurality of support rods 214. The main rod 213 is arranged along the central axis direction of the roller 21, one end of the support rod 214 is connected to the main rod 213, and the other end of the support rod 214 extends along the circumferential direction of the roller 21. The plurality of support rods 214 are arranged at intervals along the setting direction of the main rod 213. The first limiting ring 211 is fixedly connected to the roller 21, and the second limiting ring 212 is slidably connected in the guide groove.

[0038] In this embodiment, the distance between the second limiting ring 212 and the first limiting ring 211 can be adjusted through the guide groove to adapt to iron cores of different heights. A protrusion is formed on the inner surface of the second limiting ring 212, and the protrusion slides in the guide groove. When adjusting the position of the second limiting ring 212, the protrusion is pushed into the main rod 213. After moving to the desired position, the second limiting ring 212 is rotated so that the protrusion on the second limiting ring 212 slides into the corresponding support rod 214 to achieve the positioning of the second limiting ring 212 in the front and rear directions.

[0039] The force-applying assembly includes a punch head 41 and a guide block 42 . The guide block 42 is fixed on the support platform 2 by a column. The punch head 41 penetrates the guide block 42 along the Z direction. The guide block 42 guides the punch head 41 .

[0040] In this embodiment, the punch head 41 can be installed at the output end of the punching machine. At this time, the initial state of the punch head 41 is the upper state, that is, there is a certain distance between the punch head 41 and the support 2 to facilitate the entry of the terminal. The punch head 41 is driven downward by the punching machine to fix the terminal and the coil lead-out end. The punch head 41 can also be forced by a hammer head to make the punch head 41 punch the terminal in the guide of the guide block 42. At this time, the punch head 41 can be lifted manually to facilitate the insertion of the terminal, thereby reducing the convenience of moving the positioning tooling for assembling the motor terminal.

[0041] The platform 3 is also provided with a guide hole 5, which corresponds to the position of the screw hole on the wiring terminal.

[0042] In this embodiment, after the wiring terminal is placed between the platform 3 and the force-applying assembly, bolts are inserted into the screw holes and guide holes 5 on the wiring terminal to limit the angles of the screw holes on the wiring terminal for easy subsequent assembly.

[0043] The guide grooves on the two rollers 21 are arranged in a mirror image.

[0044] In this embodiment, the guide grooves arranged in a mirror image can prevent both second limiting rings 212 from being separated from the support rod 214 during the rotation of the iron core, thereby ensuring that at least one of the second limiting rings 212 can limit the iron core.

[0045] The stop bar 31 and the punch head 41 are staggered to avoid interfering with the moving distance of the punch head 41 .

[0046] That is to say, in a plan view, the stop bar 31 and the punch head 41 have no overlapping portion, thereby preventing the stop bar 31 from interfering with the punch head 41 .

[0047] There are multiple limit blocks 32, and the multiple limit blocks 32 are arranged at intervals to isolate multiple wiring terminals, so as to achieve synchronous stamping of multiple wirings on the iron core at the same time.

[0048] The positioning fixture has a simple structure, ensures the consistency of the height of the wiring terminals, and is applicable to iron cores of various sizes, thereby improving applicability.
