Description

Technical Field

[0001] This invention relates to a stator positioning and guiding wiring mechanism, belonging to the field of new energy motor manufacturing technology. Background Technology

[0002] Currently, new energy vehicles refer to automobiles that use unconventional vehicle fuels as a power source and integrate advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles, new technologies, and new structures. With the rapid development of new energy vehicles, higher requirements are being placed on the motors used in them, with motors developing towards higher power, higher speed, and higher torque. Flat wire motors can meet the requirement of higher power density. In the motor production process, copper coils need to be inserted into iron core slots: first, the copper coils are inserted into a transfer mold, and then the copper coils on the transfer mold are inserted into the iron core slots. Existing insertion machines have technical problems such as complex structure, low insertion accuracy, high defect rate, and low work efficiency.

[0003] In view of the above-mentioned shortcomings, the present invention aims to create a stator positioning and guiding insertion mechanism, which makes it more valuable for industrial applications. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the purpose of this invention is to provide a stator positioning and guiding insertion mechanism.

[0005] This invention discloses a stator positioning and guiding insertion mechanism, comprising a bottom panel and a bearing fixing plate mounted above the bottom panel. The bearing fixing plate is movably mounted with an outer guide insert plate mechanism and an inner guide fixing mechanism. The outer guide insert plate mechanism includes a disc-shaped insert plate base, in which a circular insert plate is mounted. The surface of the insert plate has multiple radially arranged arc-shaped drive grooves, each drive groove containing a guide insert. The guide inserts are connected via insert pins on their bottom surfaces. A plate chuck is concentrically fixed at the top. The surface of the plate chuck has multiple radial guide grooves, the shape of which matches the shape of the guide plate. The guide grooves on the surface of the plate chuck limit the guide plate to only contract or expand along the radius of the plate chuck. Each guide plate has two external wire insertion guide teeth at its top, which are used to guide the stator wire insertion and prevent the coil from getting messed up during insertion. The upper surface of the plate chuck is also provided with a plate cover plate, which is used to limit and fix the guide plate in the guide groove of the plate chuck.

[0006] Furthermore, the inner guide fixing mechanism includes multiple core guide pillars penetrating the bearing fixing plate. An expansion guide mechanism is fixedly connected to the top of the core guide pillars. The expansion guide mechanism includes an annular expansion upper plate and an expansion lower plate. Multiple fan-shaped outer support blocks are movably and uniformly arranged between the expansion upper plate and the expansion lower plate. An inclined tapered guide slope is provided on the inner side of the outer support block, and an inclined outer guide slope is provided on the outer side of the outer support block. An inverted conical tapered block is also provided at the center of the expansion guide mechanism. The tapered surface of the tapered block matches the outer guide slope on the outer side of the outer support block.

[0007] Furthermore, a positioning sleeve is fixedly installed on the upper surface of the bearing fixing plate for placing the wire-inserting stator. A detection sensor is also installed on one side of the bottom panel, with the detection sensor facing the position of the wire-inserting stator above the positioning sleeve, for detecting whether the wire-inserting stator has been installed on the positioning sleeve.

[0008] Furthermore, the bottom of the outer guide insert plate mechanism and the upper lifting mechanism are fixedly connected. The upper lifting mechanism includes a lifting limit plate, which is fixedly connected to the outer guide insert plate mechanism through a wire clamping plate guide post. The wire clamping plate guide post passes through the bearing fixing plate to achieve free vertical movement, and the lifting limit plate limits the maximum lifting height of the outer guide insert plate mechanism. The bottom of the upper lifting mechanism is connected to an upper lifting drive device, which provides driving force to the upper lifting mechanism, causing the upper lifting mechanism and the upper connected outer guide insert plate mechanism to move up and down.

[0009] Furthermore, a rotating connector is provided at the edge of the insert disk. The rotating connector is connected to the insert disk drive mechanism. The insert disk drive mechanism is fixedly installed at the bottom edge of the insert disk via a cylinder mounting bracket. The insert disk drive mechanism includes a turntable cylinder arranged in a horizontal direction. The output end of the turntable cylinder is connected to a drive slider. The bottom surface of the drive slider is slidably sleeved on a guide rail and can move back and forth along the guide rail. The guide rail is fixed to the surface of the cylinder mounting bracket in a horizontal direction. The top of the drive slider is connected to the rotating connector. Driven by the turntable cylinder, the drive slider and the circular insert disk on its top rotate. While rotating, under the limiting action of the insert chuck, the insert pin is driven by the drive groove, causing the guide insert to retract along the radius direction of the insert chuck. The slope of the outer insertion guide tooth at the top of the guide insert guides the stator wire insertion and prevents the outer side of the coil from becoming disordered during wire insertion.

[0010] Furthermore, a through rectangular outward expansion guide groove is provided in the middle of the outer support block, and multiple spring fixing blocks are evenly arranged on the surface of the expansion lower plate. The number of spring fixing blocks is the same as the number of outer support blocks, and the two are arranged correspondingly.

[0011] Furthermore, the outward expansion guide groove of the outer support block is sleeved on the spring fixing block, and the length of the outward expansion guide groove is greater than the length of the spring fixing block.

[0012] Furthermore, a spring is provided on the spring fixing block in the direction of the center of the expansion lower plate, with one end of the spring abutting against the spring fixing block and the other end abutting against the inner wall of the outward expansion guide groove.

[0013] Furthermore, a tapered extension rod is fixedly connected to the bottom of the tapered block, and the bottom of the tapered extension rod is connected to the output end of the inner guide drive cylinder. The bottom of the inner guide drive cylinder is fixedly connected to the surface of the bearing fixing plate.

[0014] Furthermore, the upper surface of the inner guide drive cylinder is also uniformly provided with multiple inner support blocks. The inner support blocks expand or contract under the driving action of the inner guide drive cylinder, thereby tightening or loosening the inner wall of the stator. Under normal conditions, due to the elastic force of the spring, the outer support block is in a contracted state. When it is necessary to insert wires into the stator, the inner guide drive cylinder contracts, pressing down the tapered block at its top. Through the mutual compression and transmission of the inclined surface of the tapered block and the tapered guide slope on the inner side of the outer support block, the outer support block is expanded and squeezed outward. The outer guide slope on the outer side of the outer support block guides the inner side of the coil to be inserted into the stator, preventing the inner side of the coil from becoming disordered during insertion.

[0015] By means of the above-described solution, the present invention has at least the following advantages:

[0016] In practical use, the stator positioning and guiding insertion mechanism of the present invention first pulls down the upper lifting mechanism through the driving mechanism, thereby pulling down the outer guide insert plate mechanism, the tapered block, and the expansion guide mechanism together, placing the insertion stator on the positioning sleeve. At this time, the detection sensor works, and after detecting the insertion stator, the driving mechanism starts again, pushing the upper lifting mechanism upward until the outer guide insert plate mechanism, the tapered block, and the expansion guide mechanism reach the insertion position above the insertion stator. At this time, the inner support block expands or contracts under the driving action of the inner guide driving cylinder, thereby tightening and fixing the inner wall of the insertion stator. At the same time, the drive slider and the circular insert plate on its top are driven by the turntable cylinder to rotate. Under the limiting action of the insert chuck, the insert pin is driven by the drive groove, causing the guide insert to retract along the radius of the insert chuck. The slope of the outer insertion guide tooth at the top of the guide insert guides the stator wire insertion, preventing the outer side of the coil from becoming misaligned during insertion. In addition, the inner guide drive cylinder retracts, causing the tapered block at its top to press down. The inclined surface of the tapered block and the tapered guide slope on the inner side of the outer support block squeeze and drive each other, thereby expanding and squeezing the outer support block outward. The outer guide slope on the outer side of the outer support block guides the inner side of the coil to be inserted into the stator, preventing the inner side of the coil from becoming misaligned during insertion. This operation allows for precise insertion of the stator coil, resulting in a low defect rate and high work efficiency.

[0033] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0034] See Figures 1 to 3 A preferred embodiment of the present invention provides a stator positioning and guiding insertion mechanism, comprising a bottom panel 1 and a bearing fixing plate 2 mounted above the bottom panel 1. The bearing fixing plate 2 is characterized by having an outer guide insert plate mechanism 5 and an inner guide fixing mechanism 7 movably mounted vertically. A positioning sleeve 3 is also fixedly mounted on the upper surface of the bearing fixing plate 2 for placing the insertion stator 6. A detection sensor 8 is also mounted on one side of the bottom panel 1, facing the position of the insertion stator 6 above the positioning sleeve 3, for detecting whether the insertion stator 6 has been installed on the positioning sleeve 3.

[0035] The bottom of the outer guide insert plate mechanism 5 is fixedly connected to the upper lifting mechanism 4. The upper lifting mechanism 4 includes a lifting limit plate 41. The lifting limit plate 41 is fixedly connected to the outer guide insert plate mechanism 5 through a wire clamping plate guide post 42. The wire clamping plate guide post 42 passes through the bearing fixing plate 2 to achieve free vertical movement. The lifting limit plate 41 limits the maximum lifting height of the outer guide insert plate mechanism 5. The bottom of the upper lifting mechanism 4 is connected to the upper lifting drive device. The upper lifting drive device provides driving force to the upper lifting mechanism 4, driving the upper lifting mechanism 4 and the upper connected outer guide insert plate mechanism 5 to move up and down.

[0036] See Figures 4-6 The outer guide insert plate mechanism 5 includes a disc-shaped insert plate base 521, in which a circular insert plate 525 is installed. The surface of the insert plate 525 has multiple radially arranged arc-shaped drive grooves 5252. Each drive groove 5252 contains a guide insert 524, which is connected via insert pins 5241 on its bottom surface. A insert chuck 522 is concentrically fixed above the circular insert plate 525. The surface of the insert chuck 522 has multiple radially arranged... The guide groove is shaped to match the shape of the guide insert 524. The guide groove on the surface of the insert chuck 522 limits the guide insert 524 to contract or expand only along the radius of the insert chuck 522. Each guide insert 524 has two external wire insertion guide teeth 5242 at its top end, which are used to guide the stator wire insertion and prevent the coil from getting messed up during insertion. The upper surface of the insert chuck 522 is also provided with an insert cover plate 523, which is used to limit and fix the guide insert 524 in the guide groove of the insert chuck 522.

[0037] A rotating connector 5251 is provided at the edge of the insert disk 525. The rotating connector 5251 is connected to the insert disk drive mechanism. The insert disk drive mechanism is fixedly mounted on the bottom edge of the insert disk chassis 521 via a cylinder mounting bracket 514. The insert disk drive mechanism includes a turntable cylinder 511 arranged in a horizontal direction. The output end of the turntable cylinder 511 is connected to a drive slider 512. The bottom surface of the drive slider is slidably sleeved on a guide rail 513. The guide rail 513 is fixed in a horizontal direction to the surface of the cylinder mounting bracket 514 and can move along the guide rail. The drive slider 512 moves back and forth on the slide rail 513. The top of the drive slider 512 and the rotating connector 5251 are connected by transmission. Driven by the turntable cylinder 511, the drive slider 512 and the circular insert disk 525 on its top rotate. While rotating, under the limiting action of the insert chuck 522, the insert chuck post 5241 is driven by the drive groove 5252, which drives the guide insert 524 to retract along the radial direction of the insert chuck 522. The slope of the outer wire guide tooth 5242 at the top of the guide insert 524 is used to guide the stator wire insertion and prevent the outer side of the coil from being messed up during wire insertion.

[0038] See Figures 7-10The inner guide fixing mechanism 7 includes multiple core guide posts 71 that penetrate the bearing fixing plate 2. The bottom of each core guide post 71 is fixedly connected to the surface of the lifting limiting plate 41. The top of each core guide post 71 is fixedly connected to an expansion guide mechanism 76, which is used to guide the coil inside when inserting the stator wire. The expansion guide mechanism 76 includes an annular expansion upper plate 761 and an expansion lower plate 763. Multiple fan-shaped outer support blocks 762 are movably and evenly arranged between the expansion upper plate 761 and the expansion lower plate 763. The outer support block 762 also has a through rectangular outward expansion guide groove 7621 in the middle. The surface of the expansion lower plate 763 is uniformly... Multiple spring fixing blocks 7631 are evenly arranged, the number of which is the same as the number of outer support blocks 762, and they are arranged correspondingly. The outward expansion guide groove 7621 of the outer support block 762 is sleeved on the spring fixing block 7631, and the length of the outward expansion guide groove 7621 is greater than the length of the spring fixing block 7631. A spring 7632 is arranged on the spring fixing block 7631 facing the center of the expansion lower plate 763. One end of the spring 7632 abuts against the spring fixing block 7631, and the other end abuts against the inner wall of the outward expansion guide groove 7621. The inner side of the outer support block 762 is provided with an inclined tapered guide slope 7623. The outer support block 762 has an inclined outer guide slope 7622 on its outer side. At the center of the expansion guide mechanism 76, there is also an inverted conical tapered block 75. The tapered surface of the tapered block 75 matches the outer guide slope 7622 on the outer side of the outer support block 762. A tapered extension rod 74 is fixedly connected to the bottom of the tapered block 75. The bottom of the tapered extension rod 74 is drively connected to the output end of the inner guide drive cylinder 72. The bottom of the inner guide drive cylinder 72 is fixedly connected to the surface of the bearing fixing plate 2. Multiple inner support blocks 73 are evenly arranged on the upper surface of the inner guide drive cylinder 72. The inner support blocks 73 are driven by the inner guide drive cylinder 72. The action expands or contracts, thereby tightening or loosening the inner wall of the stator 6. Under normal conditions, due to the elastic force of the spring 7632, the outer support block 762 is in a contracted state. When it is necessary to insert wires into the stator 6, the inner guide drive cylinder 72 contracts, causing the tapered block 75 at its top to press down. Through the mutual compression and transmission between the inclined surface of the tapered block 75 and the tapered guide slope 7623 on the inner side of the outer support block 762, the outer support block 762 is expanded and squeezed outward. The outer guide slope 7622 on the outer side of the outer support block 762 guides the inner side of the coil to be inserted into the stator 6, preventing the inner side of the coil from becoming disordered during insertion.

[0039] The working principle of this invention is as follows:

[0040] In actual use, the stator positioning and guiding insertion mechanism of the present invention, due to the effect of gravity, initially positions of the outer guide insert plate mechanism 5, the tapered block 75, and the expansion guide mechanism 76 are at their lowest points. Then, the insertion stator 6 is placed on the positioning sleeve 3. At this time, the detection sensor 8 operates, and after detecting the insertion stator 6, the drive mechanism starts again, pushing the upper lifting mechanism 4 upwards until the outer guide insert plate mechanism 5, the tapered block 75, and the expansion guide mechanism 76 reach the insertion position above the insertion stator 6. At this time, the inner support block 73 expands or contracts under the driving action of the inner guide drive cylinder 72, thereby tightening and fixing the inner wall of the insertion stator 6. Simultaneously, driven by the turntable cylinder 511, the drive slider 512 and its top circular insert plate 525 rotate. During rotation, the insert chuck 5... Under the limiting action of 22, the insert chuck 5241 is driven by the drive groove 5252, which causes the guide insert 524 to retract along the radial direction of the insert chuck 522. The slope of the outer wire guide tooth 5242 at the top of the guide insert 524 guides the stator wire insertion and prevents the outer side of the coil from being misaligned during insertion. In addition, the inner guide drive cylinder 72 retracts, causing the tapered block 75 at its top to press down. The inclined surface of the tapered block 75 and the tapered guide slope 7623 on the inner side of the outer support block 762 squeeze each other, thereby expanding and squeezing the outer support block 762 outward. The outer guide slope 7622 on the outer side of the outer support block 762 guides the inner side of the coil to be inserted in the stator 6, preventing the inner side of the coil from being misaligned during insertion. This operation allows for precise insertion of the stator coil.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
