[0035] like Figure 1-8 As shown, this embodiment provides a mold indexing and positioning device, wherein the mold 1 is a stator winding and inserting mold, and the mold 1 includes a conveying base plate 11 and a mold head 12. The mold head 12 is horizontally rotatably mounted on the conveying base plate 11 by means of a bearing, and the conveying base plate 11 can drive the mold head 12 to move along the conveying line; an elastically retractable positioning pin 111 is provided on the conveying base plate 11, and a corresponding positioning slot 121 is provided on the mold head 12. When the positioning pin 111 is inserted into the positioning slot 121, the mold head 12 can be positioned, so that the mold head 12 cannot rotate relative to the conveying base plate 11.

[0036] Furthermore, the indexing and positioning device also includes a guide groove 2 provided at a station requiring indexing, and the station requiring indexing may be selected but not limited to a stator winding station 4. The mold 1 moves on the conveyor line. When the mold 1 does not move to the station requiring indexing, for example, when moving before and after the station requiring indexing, the positioning pin 111 is inserted into the positioning slot 121 under the action of elastic force to position the mold head 12, and the mold head 12 cannot rotate relative to the conveying bottom plate 11; when the mold 1 starts to move to the station requiring indexing, the positioning pin 111 gradually retracts under the action of the guide groove 2 to release the positioning cooperation with the positioning slot 121. When the positioning pin 111 is completely separated from the positioning slot 121, the mold head 12 can rotate relative to the conveying bottom plate 11, that is, it can perform the indexing action.

[0037] In this way, a mold indexing and positioning device provided in this embodiment can achieve limited rotation positioning by inserting the positioning pin 111 into the positioning slot 121 at a station on the conveyor line that does not require indexing. When moving to a station that requires indexing, the limited rotation positioning can be adaptively released through the guide groove 2, so that the mold head 12 can perform an indexing action, and there is no need to set a drive component to control the action of the positioning pin 111. The structure is simple and the cost is low.

[0038] like Figure 7-8 As shown, the conveyor line is provided with a guide plate 21 at each station requiring indexing, and the guide groove 2 is formed at the bottom of each guide plate 21. Figure 5 As shown, a guide bearing 112 is connected to the positioning pin 111 through a vertical rod 113. When guiding, the guide bearing 112 rolls horizontally in the guide groove 2, which can reduce friction and make the movement smoother. A spring 114 is provided at the tail end of the positioning pin 111, and the spring 114 is pressed against a fixed plate 115, so that the elastic telescopic movement of the positioning pin 111 is realized.

[0039] Furthermore, the guide groove 2 includes two symmetrical guide bevel sections 22, which are respectively arranged on the inlet side and the outlet side. The guide bevel section 22 on the inlet side is used to gradually retract the positioning pin 111 to release the positioning cooperation with the positioning slot 121, so that the indexing action can be performed; the guide bevel section 22 on the outlet side is used to gradually extend the positioning pin 111 again, so as to re-position the limited rotation after the indexing action is completed. In this way, through the cooperation of the guide groove 2 and the guide bearing 112, the positioning pin 111 can be horizontally extended toward the die head 12 before and after the indexing, and the positioning pin 111 can be horizontally retracted away from the die head 12 when the indexing is required. Preferably, a guide arc surface 23 is also formed at the entrance of the guide groove 2 to guide the guide bearing 112.

[0040] The mold indexing and positioning device of this embodiment also includes a driving assembly 3 fixedly mounted at the workstation that needs indexing. After the positioning pin 111 is fully retracted under the action of the guide groove 2, the driving assembly 3 can drive the mold head 12 to perform an indexing action. Specifically, the driving assembly 3 includes a driving motor 31 and a connecting seat 32. A transmission block 321 is formed on the connecting seat 32. A transmission notch 122 is formed horizontally through the bottom of the mold head 12. When the positioning pin 111 begins to retract under the action of the guide groove 2, the transmission block 321 also begins to be inserted into the transmission notch 122; when the positioning pin 111 is fully retracted, the transmission block 321 is fully inserted into the transmission notch 122, and the driving motor 31 can drive the mold head 12 to rotate through the connecting seat 32 to perform an indexing action. The shape and size of the transmission block 321 and the transmission notch 122 can be set as needed so that the connecting seat 32 can drive the mold head 12 to rotate.

[0041] In the driving assembly 3, the driving motor 31 and the connecting seat 32 can correspond to each other one by one, that is, one driving motor 31 drives one connecting seat 32 to rotate, and one connecting seat 32 receives and drives one mold head 12 to rotate. Alternatively, in the driving assembly 3, one driving motor 31 corresponds to multiple connecting seats 32, for example Figure 7 As shown, there are two driving motors 31 and six connecting seats 32. Each driving motor 31 drives three connecting seats 32 to rotate synchronously through a transmission belt 33. Each connecting seat 32 is connected to and drives a mold head 12 to rotate accordingly. At this time, the guide grooves 2 also correspond to the mold heads 12 one by one, for example Figure 7 As shown, six guide plates 21 are included in total, and a guide groove 2 is provided on each guide plate 21 .

[0042] like Figure 1 The winding machine 41 of this embodiment is a six-head winding machine, that is, the winding station 4 includes six indexing positions, such as Figure 7 When the first mold 1 on the conveyor line moves, it will pass through the first five indexing positions to the last indexing position, and when the second mold 1 moves, it will pass through the first four indexing positions to the second to last indexing position, and so on. The six molds 1 move to six corresponding indexing positions; when the mold 1 passes through each indexing position, its positioning pin 111 will first retract and then extend under the action of the guide groove 2.

[0043] The conveyor line is preferably a circulating conveyor line, which is provided with stations such as paper insertion, wire winding and wire embedding, and the mold 1 circulates between these stations on the circulating conveyor line; when the mold 1 passes through a station that requires indexing, such as the wire winding station 4, the positioning pin 111 first retracts under the action of the guide groove 2 so that the mold 1 can perform the indexing action. After the indexing is completed, the positioning pin 111 can be extended again to cooperate with the positioning slot 121 to limit the rotation and position. The circulating conveyor line can be optionally but not limited to a horizontal square, a horizontal runway or a vertical square. For example, it is formed as a vertical square circulating conveyor line as described in the utility model patent with publication number "CN203229194U" and name "Motor automatic assembly circulating conveyor line", and each mold 1 can be driven by a synchronous belt. When the six molds 1 are driven to the winding machine 41, that is, the winding station 4, indexing and winding can be performed; or in other embodiments, it can also be formed into a square or runway-shaped structure on a horizontal plane, that is, each mold 1 is operated on a square or runway-shaped assembly line, and can be indexed and wound when it is operated to the winding machine 41, that is, the winding station 4.

[0044] It can be seen from the above content that the mold indexing and positioning device provided in this embodiment can adaptively realize the indexing and positioning of the mold on the conveyor line, which facilitates the operation of the mold at each workstation.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
