Description

Technical Field

[0001] The utility model relates to the technical field related to motor manufacturing, in particular to a mounting mechanism for insulating parts used for processing a stator core monomer. Background Art

[0002] At present, the use of motors is increasing, and the requirements for the stator core, which is an indispensable part of the motor, are also getting higher and higher. In the current production process of stator cores, in order to facilitate winding and improve the winding qualification rate, each sector-shaped stator core monomer is generally manufactured and processed separately first, and then all stator core monomers are spliced ​​together along the circumference to form a complete stator core.

[0003] When manufacturing and processing the existing stator core monomer, usually a wire is first wound around an insulating member by a winding device to form a coil, and then the insulating member with the coil is put on the tooth portion of the stator core monomer and fixed in position. The operation is simple and convenient, and the processing efficiency is high.

[0004] The existing winding device has a relatively simple structure. Generally, the insulating part is first placed on a flat plate, and then the insulating part is pressed down from top to bottom by a pressure plate above the flat plate to fix it. However, this method only achieves the axial fixation of the insulating part. Since the insulating part lacks radial positioning, the insulating part is easily radially offset due to the tension of the wire during the winding process, resulting in poor winding quality of the coil and even loose coils.

[0005] In summary, there is currently a need for an installation mechanism for insulating parts used in stator core monomer processing that can fully position the insulating parts. Utility Model Content

[0006] The utility model aims to overcome the shortcomings of the prior art that the insulating parts lack radial positioning and are easily radially offset due to the pulling force of the wire, resulting in poor winding quality of the coil and even loose coils. The utility model provides an installation mechanism for the insulating parts for stator core monomer processing, which can comprehensively position the insulating parts.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A mounting mechanism for insulating parts used for processing a stator core monomer comprises a platform panel, wherein a placement plate and a lower pressure plate are provided on the platform panel, wherein the placement plate is placed above the platform panel and the two are fixedly connected via a plurality of fixing columns, wherein the upper end surface of the placement plate is provided with a plurality of movable top blocks, wherein the movable top blocks are distributed in an annular shape on the placement plate and the two are slidably connected, wherein the lower pressure plate is located directly above the placement plate, and the lower pressure plate and the platform panel are movably connected up and down.

[0009] When fixing, the operator first places the insulating part on the placement plate (the movable top block is located on the inner side of the insulating part), and then controls all the movable top blocks to move outward synchronously so that the movable top blocks are pressed against the inner wall of the insulating part to achieve radial positioning of the insulating part, and then controls the upper lower pressure plate to press the insulating part from top to bottom to achieve axial positioning of the insulating part, thereby completing the comprehensive positioning of the insulating part, improving the fixing effect of the insulating part, avoiding the deviation of the insulating part due to the pulling force of the wire, and thus improving the winding quality of the coil.

[0010] Preferably, a guide slider is fixed to the bottom of the movable top block, a guide slot matching the guide slider is provided on the placement plate, the movable top block is installed on the placement plate and slidably connected thereto through the cooperation of the guide slider and the guide slot, a synchronous control mechanism connected to the movable top block is provided on the platform panel, a return spring is also provided in the guide slot, one end of the return spring is connected to the guide slider, and the other end of the return spring is connected to the end wall of the guide slot. When fixed, all movable top blocks are controlled to move synchronously outwards through the synchronous control mechanism, and the cooperation design of the guide slider and the guide slot plays a guiding and limiting role in the movement of the movable top block, thereby improving the movement accuracy. The return spring plays an automatic resetting role for the movable top block, so that it loosens the insulating part so that it can be removed.

[0011] Preferably, the synchronous control mechanism includes a rotating column installed on the lower end surface of the placement plate, the movable top block is distributed in a ring shape with the rotating column as the central axis, the rotating column and the guide slider are connected through a rocker rod and a connecting rod, one end of the rocker rod is fixed on the outer wall of the rotating column, the other end of the rocker rod is hinged to one end of the connecting rod, and the other end of the connecting rod is hinged to the guide slider. During operation, the staff rotates the rotating column to drive the rocker rod and the connecting rod thereon to move, and under the motion transmission of the rocker rod and the connecting rod, all the guide sliders will be driven to move outward along the guide slot synchronously (the reset spring is stretched), and then the movable top block on the guide slider moves outward synchronously and presses against the inner wall of the insulating part to complete the radial fixation of the insulating part, which is easy to operate and has a good fixing effect.

[0012] Preferably, a limiting ring block is fixed on the top of the rotating column, and a limiting ring groove matching the limiting ring block is provided on the lower end surface of the placement plate, and the limiting ring block is placed in the limiting ring groove and rotatably connected thereto. The cooperation between the limiting ring block and the limiting ring groove facilitates the installation of the rotating column on the placement plate, and at the same time, it plays a role in guiding and limiting the rotation of the rotating column, thereby improving the motion accuracy.

[0013] Preferably, the platform panel is provided with a panel through hole matching the rotating column, the bottom end of the rotating column passes through the panel through hole and a fastening nut is installed thereon, the width of the fastening nut is greater than the width of the panel through hole, and the outer side wall of the bottom end of the rotating column is provided with an external thread area matching the fastening nut, the fastening nut is installed on the external thread area and is threadedly connected thereto. When all the movable top blocks are synchronously supported against the insulating member, the rotating column can be locked by tightening the fastening nut on the external thread area onto the platform panel, thereby improving the fixing effect of the insulating member.

[0014] Preferably, a fixing bracket is fixed on the platform panel, the fixing bracket is placed on the side of the placement plate, a cylinder is installed on the fixing bracket, the lower pressing plate is fixed on the piston rod of the cylinder, and a flexible buffer layer is fixed on the side of the lower pressing plate facing the placement plate. After the insulating part is radially positioned, the lower pressing plate is controlled by the cylinder to move from top to bottom, and the axial positioning of the insulating part can be achieved by pressing the insulating part. The design of the flexible buffer layer can reduce the extrusion stress of the lower pressing plate on the insulating part, thereby protecting the insulating part.
