[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-4 As shown, a stator wire pressing device includes a workbench 1 and a wire body 2. Multiple trays 3 that move along the wire body 2 are provided on the wire body 2. A wire insertion fixture 4 is placed on the upper side of the tray 3. The wire insertion fixture 4 in this technical solution has the same structure and wire insertion principle as the accompanying wire insertion fixture 4 in the utility model with patent application number 202322880329.9, and will not be described again here. At least one set of lifting components 5 is provided in the workbench 1. The lifting components 5 are arranged linearly along the wire body 2 and located below the wire body 2. The trays 3 can be moved to the top of the lifting components 5 so that the lifting components 5 can push the trays 3 upward. A wire pressing component 7 for pressing down the copper wire at the end of the stator is provided on the upper side of the workbench 1. The wire pressing component 7 and the wire holding component 6 can cooperate with each other to fix and press down the end of the stator copper wire.

[0021] In use, the insertion fixture 4 is placed on the tray 3 and moves with the line body 2 to directly above the lifting component 5. The lifting component 5 pushes the tray 3 to move the insertion fixture 4 upward to a certain height. The operator pre-inserts the wires into the insertion fixture 4 according to the stator production requirements. After the insertion fixture 4 is pre-inserted, the wire-holding component 6 holds the pre-inserted copper wire from the outer peripheral wall to prevent the copper wire from shifting and causing damage during pressing, which would affect the pressing efficiency. After the wire-holding component 6 holds the copper wire, the pressing component 7 and the wire-holding component 6 work together to press the pre-inserted copper wire into the insertion fixture 4. After pressing, the pressing component 7 and the wire-holding component 6 are reset. The lifting component 5 moves the tray 3 down onto the line body 2 and flows with the line body 2 to the next station. This technical solution can perform pressing operations on two insertion fixtures 4 at the same time, effectively improving the working efficiency when pressing the insertion fixture 4.

[0022] In this embodiment, the lifting assembly 5 includes a fixed plate 501 bolted to the workbench 1, a second cylinder 504 bolted to the lower side of the fixed plate 501, and a lifting plate 502 positioned above the fixed plate 501. The output shaft of the second cylinder 504 passes through the fixed plate 501 and is fixedly connected to the lower side of the lifting plate 502. Four second guide shafts 503 are arranged in a rectangular array on the lower side of the lifting plate 502 by bolts. The four second guide shafts 503 are slidably connected to the fixed plate 501 through linear bearings. The lower sides of the four second guide shafts 503 are all connected to the same synchronous plate 505. When the tray 3 moves with the line 2 to directly above the lifting plate 502, the output shaft of the second cylinder 504 pushes the lifting plate 502 upward. The upper side of the lifting plate 502 contacts the tray 3, thereby pushing the tray 3 upward, thus realizing the adjustment of the height of the wire insertion fixture 4, which facilitates the subsequent pre-insertion and crimping of the wire insertion fixture 4 by the operator.

[0023] In this embodiment, multiple limiting posts 506 are bolted to the upper side of the lifting plate 502, and multiple limiting grooves are opened on the lower side of the tray 3 for inserting the limiting posts 506. The limiting grooves correspond one-to-one with the limiting posts 506. When the lifting plate 502 lifts the tray 3, the limiting posts 506 are inserted into the limiting grooves on the lower side of the tray 3 to limit the tray 3 and improve the stability of the lifting plate 502 when lifting the tray 3.

[0024] In this embodiment, the wire-holding assembly 6 includes two base plates 601 bolted to the upper side of the workbench 1, two mounting plates 602 respectively disposed above the two base plates 601, two first cylinders 606 bolted to the lower side of the two mounting plates 602, a top plate 603 disposed above the two mounting plates 602, and at least one set of wire-holding parts disposed on the upper side of the top plate 603. The base plates 601 and the mounting plates 602 are connected and fixed by two connecting plates 605 and bolts. Two first guide shafts 604 are provided through each of the two base plates 601. The two first guide shafts 604 are located at the left and right ends of the base plates 601 respectively. The first guide shafts 604 are slidably connected to the mounting plates 602 by linear bearings, and the upper ends of the first guide shafts 604 pass through the mounting plates. 602 is connected to the lower side of the top plate 603. The output shaft of the first cylinder 606 passes through the mounting plate 602 and is fixedly connected to the lower side of the top plate 603. At least one circular through slot 610 is provided on the top plate 603. The number of wire-holding parts, circular through slots 610 and lifting components 5 are the same and their positions correspond vertically. After the worker pre-inserts the wire into the insertion tool 4, the worker controls the wire-holding part to fix the end of the pre-inserted copper wire. Then the wire-pressing component 7 presses down the end of the copper wire, so that the pre-inserted copper wire is inserted into the insertion tool 4. At the same time as the wire-pressing component 7 presses down, the first cylinder 606 controls the top plate 603 to descend synchronously with the wire-pressing component 7, so that the wire-holding part always fixes the end of the copper wire, and the upper side of the wire-holding part always contacts the wire-pressing component 7 to prevent the copper wire from shifting when pressed down.

[0025] In this embodiment, the wire-holding part includes four sliding cylinders 608 bolted to the upper side of the top plate 603 and a wire-holding push plate 609 disposed at the output end of the sliding cylinders 608. The four sliding cylinders 608 are arranged in a ring array around the circular through slot 610. When fixing the pre-inserted copper wire, the operator controls the sliding cylinders 608 to push the wire-holding push plate 609 toward the copper wire. At the same time, the side of the wire-holding push plate 609 near the copper wire fits against the circumferential side of the end of the copper wire, limiting the end of the copper wire. Meanwhile, when the wire pressing assembly 7 presses in the copper wire, the wire pressing assembly 7 is always in contact with the upper side of the wire-holding push plate 609, thereby achieving the fixing and guidance of the end of the copper wire during the wire pressing process.

[0026] In this embodiment, the wire pressing assembly 7 includes an assembly frame 701 mounted on the upper side of the workbench 1 by bolts, and two sets of wire pressing parts symmetrically arranged on the left and right sides of the assembly frame 701 near the side of the line body 2. The two sets of wire pressing parts and the wire holding parts correspond one-to-one with the two sets of lifting assemblies 5.

[0027] In this embodiment, the pressing part includes a lifting plate 703 that is slidably connected to the side of the assembly frame 701 near the line body 2, an electric cylinder mounting plate 707 that is bolted to the upper side of the assembly frame 701, a servo electric cylinder 708 that is bolted to the upper side of the electric cylinder mounting plate 707, two horizontal moving plates 704 that are slidably connected to the side of the lifting plate 703 near the line body 2, two pressing plates 705 that are symmetrically arranged with bolts on the two horizontal moving plates 704 near the side of the line body 2, a third cylinder 706 that is bolted to the upper side of one of the pressing plates 705, and a connecting block 709 that is bolted to the upper side of the other pressing plate 705. The output shaft of the third cylinder 706 is fixedly connected to the connecting block 709. The output end of the servo electric cylinder 708 passes through the electric cylinder mounting plate 707 and is fixedly connected to the lifting plate 703. The ends of the two pressing plates 705 away from the horizontal moving plates 704 can be fitted into a ring shape.

[0028] When pressing in the pre-inserted copper wire, the operator controls the third cylinder 706 to adjust the distance between the two pressing plates 705 to match the pre-inserted copper wire on the insertion fixture 4. Then, the servo cylinder 708 pushes the lifting plate 703 downward, so that the lower side of the pressing plate 705 is in contact with the wire-holding push plate 609 and the upper side of the copper wire. At this time, the upper side of the pre-inserted copper wire, the lower side of the pressing plate 705, and the upper side of the wire-holding push plate 609 are on the same horizontal line. Then, the servo cylinder 708 continues to drive the lifting plate 703 downward, so that the pressing plate 705 presses the pre-inserted copper wire into the insertion fixture 4. While the pressing plate 705 is descending, the first cylinder 606 drives the top plate 603 downward, so that the wire-holding push plate 609 always holds the end of the pre-inserted copper wire, ensuring the stability of the copper wire when pressing down.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
