Description

Technical Field

[0001] This invention relates to a flat wire motor torsion head device for a new energy vehicle™ system, belonging to the field of automation equipment technology. Background Technology

[0002] During the production process of stator coils, the flat wire ends of the coils need to be processed by a twisting machine. The traditional processing method involves manually placing the stator coils on a separate twisting mechanism and manually operating the mechanism to perform the twisting action. This method has been gradually phased out due to problems such as wasting manpower and low efficiency. At present, the twisting processing of stator coils is mostly carried out in the form of automated equipment, such as the patent document CN217282604U "Twisting Machine for Flat Wire Motors". This patent adopts an automatic loading and unloading method combined with an automatic twisting mechanism. Although it improves efficiency, it still has shortcomings, including the lack of a mechanism to cooperate with the production line, the independent operation of the pin insertion mechanism and the transfer mechanism at the upper end of the stator coil, the complexity of the operation, and the overall lifting of the twisting mechanism, resulting in high load and poor stability.

[0039] The lifting frame 13 is equipped with an upper pin insertion mechanism 6, an expansion sleeve assembly 16, and an expansion sleeve driving device 17. The upper pin insertion mechanism 6 is fixed to the lifting frame 13 by an upper pin insertion disc locking cylinder 19.

The expansion sleeve assembly 16 is used to grip the stator coil from the inside. The upper pin insertion mechanism 6 can fix the upper coil of the gripped stator.

[0040] Locking components 23 are provided at the four corners of the upper slide 12. The locking components 23 are used to cooperate with the positioning block 21. The locking components 23 can be existing start-up or electric locking tongues. After the upper slide 12 moves to the turning head processing position, the locking tongue locks the locking hole on the positioning block 21, which can lock the upper slide 12 in the current position.

[0041] Limit blocks 22 are provided at both the front and rear ends of the upper platform 11, and hard limit buffer blocks 24 are provided on both the front and rear sides of the upper slide 12.

[0042] refer to Figure 5-8The upper pin insertion mechanism 6 includes a disc frame 31, a drive disc 32, and an upper pin insertion drive device 33. The drive disc 32 is coaxial with the disc frame 31 and has a swing arm structure, which is an integral structure extending from the periphery of the drive disc 32.

[0043] The upper pin drive device 33 can be a cylinder. The working end of the upper pin drive device 33 is provided with a drive slider 34. The drive slider 34 cooperates with the swing arm structure of the drive disk 32. The upper pin drive device 33 drives the drive disk 32 to rotate relative to the disk frame 31 through the drive slider 34. The disk frame 31 can be provided with a rotation guide structure that cooperates with the drive disk 32, such as an annular groove.

[0044] A connecting plate 35 is provided on the upper side of the disc frame 31. The connecting plate 35 is provided with an upper pin plate locking pin 36 and an upper pin plate positioning block 37. An upper pin plate connecting flange 38 is provided on the disc frame 31. The upper pin mechanism 6 is installed on the transfer mechanism 3 through the upper pin plate locking pin 36, the upper pin plate positioning block 37 and the upper pin plate connecting flange 38. The upper pin plate positioning block 37 is used to quickly position the disc frame 31 in the circumferential direction, the upper pin plate locking pin 36 is used to quickly position the disc frame 31 in the axial direction, and the upper pin plate connecting flange 38 is used to lock and fix the disc frame 31 to the corresponding structure on the transfer mechanism 3.

[0045] The lower side of the disc frame 31 is provided with a limiting disc 39 and a plurality of upper pins 41 arranged circumferentially along the axis of the drive disc 32. The limiting disc 39 cooperates with the disc frame 31 to guide the plurality of upper pins 41, so that each upper pin 41 can move radially along the disc frame 31. Each upper pin 41 is provided with an upper tracking wheel 42. The drive disc 32 is provided with a plurality of arc-shaped guide grooves 43 arranged circumferentially along the axis of the drive disc 32. The tracking wheel 42 cooperates with the arc-shaped guide grooves 43. In this embodiment, in order to arrange a larger number of upper pins 41, each arc-shaped guide groove 43 is matched with the upper tracking wheel 42 of three upper pins 41, so that the upper pins 41 can be arranged more densely.

[0046] refer to Figure 9-11 The lower pin lifting mechanism 4 includes a fixed base plate 51, a lower pin lifting drive device 52, a lower pin lifting platform 53, and a lower pin assembly. The lower pin lifting drive device 52 is a servo electric cylinder. There are two sets of lower pin lifting drive devices 52, which are symmetrically arranged on the left and right sides of the fixed base plate 51 and the lower pin lifting platform 53. The fixed base plate 51 and the lower pin lifting platform 53 are connected by four sets of evenly distributed lifting guide columns, so that the lower pin lifting drive device 52 can drive the lower pin lifting platform 53 to rise and fall smoothly.

[0047] The lower pin lifting platform 53 is provided with a lower pin mounting groove 54. The lower pin assembly includes a lower pin driving device 61, a lower pin mounting plate 62, and a lower pin turntable 63. The lower pin mounting plate 62 is fixedly mounted on the lower pin mounting groove 54. The lower pin driving device 61 can be a geared motor. A large turntable gear 67 is machined around the lower pin turntable 63. A small turntable gear 68 is provided on the geared motor. The small turntable gear 68 meshes with the large turntable gear 67. The geared motor drives the lower pin turntable 63 to rotate through the small turntable gear 68.

[0048] The lower pin mounting plate 62 is provided with a plurality of lower pin guide grooves 64 arranged circumferentially along the axis of the lower pin turntable 63. Each lower pin guide groove 64 is provided with a lower pin 65. The direction of the lower pin guide groove 64 is radial to the lower pin turntable 63. The lower pin turntable 63 is provided with a continuous spiral groove 66. Each lower pin 65 is provided with a guide component, such as a roller, that cooperates with the spiral groove 66. During the rotation of the lower pin turntable 63, the spiral groove 66 can drive the lower pin 65 to move along the lower pin guide groove 64 through the guide component.

[0049] refer to Figure 12-16 The head-turning mechanism 5 includes a head-turning fixing component and a head-turning lifting component. The head-turning fixing component includes a head-turning fixing frame 71, several sets of head-turning drive devices 72, and several layers of gear rings 73. The head-turning lifting component includes several mold end rotating shafts 81 and several equipment end rotating shafts 82. The number of head-turning drive devices 72, gear rings 73, mold end rotating shafts 81, and equipment end rotating shafts 82 are the same, and in this embodiment, there are eight sets of each.

[0050] The aforementioned sets of torsion drive devices 72 are fixedly installed on the torsion fixing frame 71. The torsion drive device 72 can be a geared motor. Each set of torsion drive devices 72 is engaged with a layer of gear rings 73 through a small gear set 74. Among the aforementioned layers of gear rings 73, the bottommost gear ring 73 is engaged with the torsion fixing frame 71 through a bearing structure. Every two adjacent layers of gear rings 73 are also engaged through a bearing structure, which can ensure that all gear rings 73 rotate stably.

[0051] The height, inner diameter and outer diameter of the multi-layer gear ring 73 are exactly the same. Each layer of gear ring 73 has multiple evenly distributed vertical guide grooves 75 on its inner ring, and the number of vertical guide grooves 75 in each layer of gear ring 73 is the same.

[0052] The lower ends of the aforementioned several ring-shaped device end shafts 82 are located on the inner side of a gear ring 73 from top to bottom, from the outer ring to the inner ring. Each device end shaft 82 is provided with a roller mounting plate 83 at its lower end. The roller mounting plate 83 is a ring structure. Each roller mounting plate 83 is provided with multiple outward protrusions. The number of protrusions on each roller mounting plate 83 is the same as the number of vertical guide grooves 75 in each gear ring 73. A lower shaft roller 84 is installed on each protrusion. The lower shaft roller 84 enters the vertical guide groove 75 of the gear ring 73 in the same layer. The lower shaft roller 84 is clearance-fitted with the left and right side walls of the vertical guide groove 75.

[0053] In this embodiment, the height of the vertical guide groove 75 is equal to the thickness of the gear ring 73, that is, the vertical guide groove 75 is a through groove in the vertical direction on the inner side of the gear ring 73, which facilitates assembly. The height of the vertical guide groove 75 is greater than the maximum lifting distance of the twisting head lifting assembly, which can ensure that the lower rotating shaft roller 84 will not come out of the vertical guide groove 75 during the lifting process of the twisting head lifting assembly.

[0054] The outer diameter of the lower end of the plurality of rotating shafts 82 decreases from the outside to the inside. The outer diameter of the roller mounting discs 83 on the plurality of rotating shafts 82 is the same, while the inner diameter decreases from top to bottom, forming a stepped arrangement. The lower end of the innermost rotating shaft 82 is connected to the torsion head fixing frame 71 through a bearing structure. The roller mounting discs 83 of every two adjacent rotating shafts 82 are connected to each other through a receiving component 87. Each receiving component 87 is divided into upper and lower annular parts. The upper annular part is connected to the bottom of the upper roller mounting disc 83, and the lower annular part is connected to the upper part of the lower roller mounting disc 83. The upper and lower annular parts are connected through a bearing structure, so that the rotating shafts 82 and roller mounting discs 83 can be supported step by step without affecting rotation and maintaining rotational independence.

[0055] The upper ends of the plurality of machine end rotating shafts 82 are sequentially and fixedly connected to the lower ends of the plurality of mold end rotating shafts 81. In each pair of adjacent mold end rotating shafts 81, the inner mold end rotating shaft 81 is provided with a plurality of upper rotating shaft rollers 85, and the outer mold end rotating shaft 81 is provided with a plurality of transverse limiting slots 86. Each upper rotating shaft roller 85 enters a limiting slot 86, and the upper rotating shaft roller 85 and the upper and lower side walls of the limiting slot 86 are in clearance fit.

[0056] With this structure, when any one or more mold end shafts 81 are lifted or lowered by an external force, the other mold end shafts 81 are also driven to rise and fall together under the cooperation of the upper shaft roller 85 and the limiting groove 86, without affecting the relative rotation between the individual mold end shafts 81. At the same time, multiple equipment end shafts 82 are also driven to rise and fall synchronously. Under the cooperation of the lower shaft roller 84 and the vertical guide groove 75, the gear ring 73 can still drive the equipment end shaft 82 to rotate, thereby driving the mold end shaft 81 to rotate for turning processing.

[0057] As an alternative, a torsion head connecting flange 76 is provided at the upper end of the innermost mold end shaft 81. The torsion head connecting flange 76 can be connected to the middle part of the lower pin lifting mechanism 4, so that the lower pin lifting mechanism 4 can drive the torsion head lifting assembly to rise and fall relative to the torsion head fixing assembly through the torsion head connecting flange 76.

Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it.
