[0019] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 As shown, an eccentric wheel multi-station straight motor stator winding machine includes a chassis 1, and an eccentric winding mechanism 2, a clamping and cutting mechanism 3 and a feeding mechanism 4 are arranged on the chassis 1 in sequence.

[0021] like Figure 2-Figure 3 As shown, the eccentric winding mechanism 2 includes a fixed frame 21, on which an X-axis eccentric drive unit 22 and a Z-axis eccentric drive unit 23 are installed. The X-axis eccentric drive unit 22 and the Z-axis eccentric drive unit 23 are both slidably connected to the winding frame 24, and a wire nozzle mounting seat 25 is provided on the winding frame 24. In this embodiment, three winding nozzles 26 are provided on the wire nozzle mounting seat 25, which can perform winding operations on three workpieces at the same time.

[0022] The X-axis eccentric drive unit 22 includes two X-axis eccentric shafts 221 arranged symmetrically with each other. The X-axis eccentric shafts 221 are connected to the X-axis eccentric drive motor 222 through a transmission belt. The X-axis eccentric drive motor 222 and the X-axis eccentric shaft 221 are both mounted on the fixing frame 21. Figure 4 As shown, the output end of the X-axis eccentric shaft 221 is provided with an X-axis eccentric block 223, which is rotatably connected to an X-axis limit block 224. The X-axis limit block 224 is disposed in an X-axis guide slot 241 on the winding frame 24. Driven by the X-axis eccentric drive motor 222, the two X-axis eccentric shafts 221 rotate synchronously, and the X-axis eccentric block 223 drives the X-axis limit block 224 to rotate eccentrically. Under the action of the X-axis guide slot 241, the winding frame 24 is driven to move back and forth left and right.

[0023] The Z-axis eccentric drive unit 23 includes two Z-axis eccentric shafts 231 arranged symmetrically with respect to the center. The Z-axis eccentric shafts 231 are connected to the Z-axis eccentric drive motor 232 via a transmission belt. The Z-axis eccentric drive motor 232 and the Z-axis eccentric shaft 231 are both mounted on the fixed frame 21. The Z-axis eccentric shaft 231 has the same structure as the X-axis eccentric shaft 221. The output end of the Z-axis eccentric shaft 231 is provided with a Z-axis eccentric block 233, which is rotatably connected to a Z-axis limit block 234. The Z-axis limit block 234 is disposed in a Z-axis guide groove 242 on the winding frame 24. Driven by the Z-axis eccentric drive motor 232, the two Z-axis eccentric shafts 231 rotate synchronously, and the Z-axis eccentric block 233 drives the Z-axis limit block 234 to rotate eccentrically. Under the action of the Z-axis guide groove 242, the winding frame 24 is driven to move back and forth up and down.

[0024] After the composite left and right reciprocating movement and up and down reciprocating movement, the winding frame 24 makes an elliptical motion, and the motion trajectory of the winding nozzle 26 in the middle is Figure 2 As shown in the figure, the Y-axis and X-axis movement actions of the three-axis position adjustment component 41 of the feeding mechanism 4 are combined to realize the winding of the linear motor stator. At the same time, the Z-axis movement action of the three-axis position adjustment component 41 is suitable for linear motor stators of different heights.

[0025] A wire through hole 211 is provided on the fixed frame 21 for winding to pass through, and a weight-reducing through hole 243 is provided on the winding frame 24. Protective guide rails 244 are provided in the X-axis guide groove 241 and the Z-axis guide groove 242 of the winding frame 24. Anti-wear balls are provided on the protective guide rails 244 to reduce friction and make the movement smoother.

[0026] The fixed frame 21 is also provided with a fixed tensioning wheel 27 and an adjusting tensioning wheel 28 for tensioning the transmission belt. The adjusting tensioning wheel 28 is installed in the adjusting through hole 212 on the fixed frame 21, and the installation position of the adjusting tensioning wheel 28 is adjusted according to the actual tightness of the transmission belt.

[0027] The wire cutting mechanism 3 is used for intermittent winding and clamping the winding end at the same time to facilitate the next winding. The wire cutting mechanism 3 includes three wire cutting components 31, such as Figure 5 As shown, the shear line assembly 31 is set on the horizontal angle adjustment plate 33 through the mounting plate 32, and the horizontal angle adjustment plate 33 is mounted on the support column 34. The horizontal angle adjustment plate 33 can be adjusted according to the actual angle. The support column 34 is mounted on the X-axis adjustment cylinder 36, and the X-axis adjustment cylinder 36 is connected to the Y-axis adjustment cylinder 35. The Y-axis adjustment cylinder 35 is mounted on the box. The X-axis adjustment cylinder 36 and the Y-axis adjustment cylinder 35 are used to adjust the positions of the three shear line assemblies 31 to realize shear line clamping and wire feeding.

[0028] like Figure 6 As shown, the feeding mechanism 4 includes a three-axis position adjustment component 41. The three-axis position adjustment component 41 cooperates with the elliptical motion of the winding frame 24 to realize the winding of each winding position of the straight motor stator. The three-axis position adjustment component 41 is connected to a fixed seat 43 through a flip component 42. The flip component 42 is used to flip the entire fixed seat 43 to facilitate subsequent loading and unloading. The flip component 42 includes a flip drive motor 421. The flip drive motor 421 is connected to a flip shaft 422. The flip shaft 422 is installed on the chassis 1, and the fixed seat 43 is installed on the flip shaft 422. It is in a horizontal state when loading, as shown in FIG. Figure 1 After the loading is completed, the flip drive motor 421 drives the flip shaft 422 to rotate, so that the fixing seat 43 is in a vertical state, such as Figure 6 Then proceed with the winding work.

[0029] During the winding process, each winding position of the workpiece needs to be wound in sequence according to the winding order. Since the winding needs to be set at a fixed position at the beginning of each winding position, the workpiece needs to be rotated and indexed. Three indexing components 44 are provided on the fixed seat 43. Adjacent indexing components 44 are connected by a transmission belt to achieve simultaneous indexing of three workpieces. Figure 7 In order to display different angles, one of the indexing mechanisms is in a horizontal state, and the other two indexing mechanisms are in a vertical state. When in use, the angles of the three indexing mechanisms remain consistent. The indexing assembly 44 includes an indexing drive motor 441, which is connected to one of the indexing seats 442 installed on the fixed seat 43. The adjacent indexing seats 442 are connected by belt rotation. A tightening cylinder 443 is provided on the indexing seat 442. The two symmetrically arranged indexing seats 442 are connected by a limit plate 444, and a limit hole 4441 is provided on the limit plate 444. The workpiece positioning assembly 45 is detachably connected to the indexing assembly 44. Figure 8-Figure 9As shown, the workpiece positioning assembly 45 includes a workpiece base 451, and an upper pressure plate 452 and a lower pressure plate 453 are provided on one side of the workpiece base 451. The upper pressure plate 452 and the lower pressure plate 453 are adapted to the workpiece so that the upper pressure plate 452 and the lower pressure plate 453 can press the upper and lower ends of the workpiece. At the same time, a positioning plate 454 with a positioning hook 455 is provided on the lower pressure plate 453. The positioning hook 455 is clamped on the workpiece between two adjacent winding positions to realize the positioning of the winding position, so that the spacing between each winding position is uniform. The workpiece is arranged between the upper pressure plate 452 and the positioning plate 454, and a limiting pin 456 is provided on the other side of the workpiece base 451. The limiting pin 456 is inserted into the limiting hole 4441. When loading, insert the limit pin 456 of the workpiece base 451 into the limit hole 4441, the two ends of the workpiece base 451 are set with hook lines, and the extension and retraction of the tightening cylinder 443 is set as a wedge block. Start the tightening cylinder 443, and the retractable end of the tightening cylinder 443 tightens the two ends of the workpiece base 451, so that the fixed base is stably and firmly fixed on the fixed seat 43.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solutions of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
