Description

Technical Field

[0001] The utility model relates to the technical field of winding machines, in particular to a stator winding machine with switchable processing stations. Background Art

[0002] There is a Chinese utility model patent published on May 13, 2009, with the announcement number CN201237974Y, which is a replaceable tooling assembly structure. The tooling head of the winding machine can be replaced in the form of an assembly, eliminating the trouble of disassembling and installing one by one and then calibrating and positioning each time a tooling head of a different model is replaced.

[0003] However, the tooling head of the winding machine is fixed and cannot rotate, so it can only wind one unit of the stator to be wound.

After winding one unit to be wound, it is necessary to manually change the position of each stator or replace the tooling components (to align the other unit to be wound with the outlet of the winding mechanism), which is very troublesome and not only wastes manpower but also greatly reduces the processing efficiency.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present invention. The experimental methods in the following embodiments are conventional methods unless otherwise specified. The materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0033] like Figure 1-Figure 9 As shown, the utility model provides a stator winding machine with switchable processing stations, including a workbench 1, on which a tensioner 2, a wire guide mechanism 3 (the tensioner 2 and the wire guide mechanism 3 are prior art and are not described in detail here), a winding mechanism 4 and a turning tool 5 are sequentially arranged, and the turning tool 5 includes two support plates 51, a rotating rod 52, two positioning tool groups 53 and a driving assembly 54;

[0034] The rotating rod 52 is rotatably disposed between the two supporting plates 51;

[0035] Two sets of positioning tooling groups 53 are rotationally symmetrically arranged on the rotating rod 52, and each set of positioning tooling groups 53 includes a plurality of first support blocks 531 fixedly arranged on the rotating rod 52 along the length direction of the rotating rod 52 and a tooling head 532 rotatably arranged on the first support blocks 531, and the tooling head 532 is used to install the stator, and the stator includes two adjacent units to be wound (here defined as winding unit A and winding unit B);

[0036] By providing two sets of positioning tooling groups 53, when the stator on one set of positioning tooling groups 53 is being wound, the stator loading and unloading work can be performed on the other set of positioning tooling groups 53, thereby achieving continuous and uninterrupted winding work;

[0037] The driving assembly 54 includes a first driving member 547 (which can be set as a cylinder here), a second support block 541, a movable rod 542, a lever 545 and a positioning pin 546. A plurality of second support blocks 541 are fixedly installed on the rotating rod 52, and a movable rod 542 is movably penetrated on the second support block 541. A lever 545 is horizontally fixedly installed below one side of each tooling head 532. The movable rod 542 has a plurality of first through holes 5421 opened along its length direction. The lever 545 is movably arranged at In the first through hole 5421, the opening size of the first through hole 5421 is larger than the cross-sectional size of the lever 545, a second through hole 5451 is opened on the top surface of the lever 545, a plurality of positioning pins 546 are fixedly penetrated on the movable rod 542, the opening size of the second through hole 5451 is larger than the cross-sectional size of the positioning pins 546, two sides of the positioning pins 546 are in contact with two sides of the inner wall of the second through hole 5451, and the positioning pins 546 are located in the first through hole 5421 and the second through hole 5451 at the same time;

[0038] When the first driving member 547 drives the movable rod 542 to move horizontally, the movable rod 542 drives the lever 545 to rotate;

[0039] Here, the two units to be wound are set as unit A to be wound and unit B to be wound:

[0040] When it is necessary to wind the stator unit A to be wound, after the stator is installed on each tooling head 532 of a positioning tooling group 53, and each stator unit A to be wound is facing the winding mechanism 4, after the winding mechanism 4 completes the winding on the unit A to be wound, the first driving member 547 is adjusted to drive the movable rod 542 to move, and the movable rod 542 drives the lever 545 to rotate a certain angle in the first through hole 5421. At this time, the positioning pin 546 slides in the second through hole 5451, thereby driving the tooling head 532 to rotate synchronously, so that the stator unit B to be wound is facing the winding mechanism 4, so that the winding work of the unit B to be wound can be completed through the winding mechanism 4, that is, the continuous winding work of the two units to be wound on the stator is completed, without manually changing the position of each stator or replacing the tooling components, thereby greatly improving the winding processing efficiency.

[0041] The first driving member 547 can be used in the following two ways:

[0042] Embodiment 1:

[0043] like Figure 2-Figure 5 As shown, there is one first driving member 547, which is a cylinder. The first driving member 547 is fixedly arranged on a support plate 51, and the central axis of the output end of the cylinder coincides with the central axis of a movable rod 542, and the output end of the cylinder is in indirect contact with the movable rod 542. The driving assembly 54 also includes a fixed block 543 and a first elastic member 544. At least one fixed block 543 is fixed on the movable rod 542, and the first elastic member 544 is fixedly installed between at least one fixed block 543 and a second supporting block 541;

[0044] The first elastic member 544 is a spring, which is sleeved on the outer periphery of the movable rod 542. By arranging the first driving member 547 on the support plate 51, only one first driving member 547 is required, and the output end of the first driving member 547 is not fixedly connected to the movable rod 542.

[0045] When the spring is at its original length, the winding unit A faces the winding mechanism 4, and the output end of the cylinder does not contact the movable rod 542 at this time. When the winding unit A is completed, the cylinder is extended to make it contact with the movable rod 542 and drive it to move. The movable rod 542 drives the lever 545 to rotate a certain angle in the first through hole 5421, thereby driving the tooling head 532 to rotate, so that the winding unit B of the stator faces the winding mechanism 4, so that the winding work of the winding unit B can be completed through the winding mechanism 4.

[0046] After the winding unit B is finished winding, the regulating cylinder is contracted so that it is no longer in contact with the movable rod 542. After the driving rod 52 is rotated to switch the positions of the two positioning fixture groups 53, the movable rod 542 of the other positioning fixture group 53 is facing the first driving member 547. The cylinder will contact the movable rod 542 only when it is extended and drive it to move, so that the automatic winding work of the two winding units on the stator of the other positioning fixture group 53 can be completed.

[0047] Only one cylinder is required here, and the cost is relatively low. However, the first elastic member 544 may not be able to be completely reset when used too many times, which may cause the subsequent winding unit A to be unable to face the winding mechanism 4, and thus the winding unit A cannot be accurately wound, and the spring needs to be checked and replaced regularly.

[0048] Embodiment 2:

[0049] There are two first driving members 547 (not shown in the figure), the first driving members 547 are cylinders, each of the first driving members 547 is fixed to a positioning fixture group 53, and the output end of each first driving member 547 is fixedly connected to a movable rod 542;

[0050] Two first driving members 547 are provided here, each driving a movable rod 542 of a positioning tooling group 53, so that it drives the lever 545 to rotate, thereby driving the tooling head 532 to rotate, thereby completing the adjustment of the positions of the two units to be wound. The cost of use is higher than that of embodiment 1, but it can avoid the trouble of regularly checking and replacing the springs.

[0051] Specifically, Figure 6 , Figure 7 and Fig. 9 As shown, the unit to be wound is T-shaped, each unit to be wound includes a winding part and a blocking part, the winding mechanism 4 includes a moving platform 41 and a plurality of winding components 42 rotatably arranged on one side of the moving platform 41, the moving platform 41 is slidably arranged on the workbench 1, the second driving member is fixedly installed on the workbench 1, and the output end of the second driving member is fixedly connected to the moving platform 41;

[0052] The second driving member drives the movable table 41 to move back and forth away from and toward the turning tool 5, thereby driving the winding assembly 42 to move back and forth away from or toward the stator, so that the wire can be evenly wound on the winding part of the unit to be wound.

[0053] like Figure 1 , Figure 6 and Figure 7As shown, the winding assembly 42 includes a hollow cross bar 421, a wire wheel 422 and a hollow wire rod 423. The hollow cross bar 421 is rotatably arranged on one side of the moving platform 41. The wire wheel 422 is rotatably arranged on the hollow cross bar 421. The hollow wire rod 423 is fixed on the hollow cross bar 421 through a bracket. The hollow wire rod 423 is parallel to the hollow cross bar 421.

[0054] The wire passes through the tensioner 2, the wire mechanism 3, and then through the hollow cross bar 421 and the wire wheel 422 of the winding mechanism 4 in turn to enter the hollow wire rod 423, and is finally led out from the hollow wire rod 423. Several hollow cross bars 421 can be rotated synchronously by a motor and a transmission belt. When the hollow cross bar 421 rotates, the hollow wire rod 423 rotates synchronously, thereby completing the winding action. The specific winding method is the existing technology and will not be repeated here.

[0055] like Figure 7 As shown, one end of the hollow cross bar 421 is connected to a wire frame 424 through a bearing (the wire frame 424 is connected through the bearing, and the wire frame 424 itself has a certain weight, so when the hollow cross bar 421 rotates, the wire frame 424 will not move or slightly shake), the wire frame 424 is in a truncated cone or prism shape, with a large area end and a small area end, the small area end of the wire frame 424 is opposite to the stator and has a notch not less than the size of the blocking portion, and the hollow wire rod 423 is located outside the wire frame 424;

[0056] By opening a notch at the small-area end of the wire frame 424, the second driving member can drive the movable table 41 to move. When the winding assembly 42 is winding, the blocking portion is always ensured to be in the notch, thereby ensuring that the wire is completely wound around the winding portion. Here, the outer periphery of the wire frame 424 is preferably set to an arc shape, so that the wire will not be worn when it contacts it.

[0057] like Figure 7 As shown, the winding mechanism 4 also includes a blocking component 43, which is fixed to one side of the moving platform 41. The blocking component 43 includes a support seat 431 and a blocking rod 432 fixed on the support seat 431. Blocking rods 432 are provided on both sides of the wire frame 424. The height of the blocking rod 432 is higher than the height of the hollow wire rod 423. The distance between the blocking rod 432 and the flip tool 5 is smaller than the distance between the hollow wire rod 423 and the flip tool 5.

[0058] By setting the blocking rod 432 in this way, the wire can be blocked and limited to prevent it from being wound on the adjacent unit to be wound. At the same time, it can also prevent the hollow conductor rod 423 from being wound on the blocking rod 432 when rotating for winding.

[0059] like Figure 8As shown, the winding machine also includes a fixing mechanism 6, which includes a rotating plate 61, an insertion rod 64 and an adjustment component. The rotating plate 61 is fixedly mounted at one end of the rotating rod 52. Notches 611 are symmetrically provided at both ends of the rotating plate 61. One end of the insertion rod 64 is adapted to the size of the notch 611. The insertion rod 64 is located directly below the rotating plate 61. The adjustment component is used to drive the insertion rod 64 to move into the notch 611.

[0060] Specifically, a handle 66 is fixedly installed at the other end of the rotating rod 52. The rotating rod 52 can be driven to rotate by manually turning the handle 66. When the positioning tooling group 53 needs to be switched, the adjusting component is adjusted to drive the insertion rod 64 to move out of the gap 611, and then the handle 66 is held to drive the rotating rod 52 to rotate one hundred and eighty degrees, and then the adjusting component is adjusted to drive the insertion rod 64 to move into another gap 611, thereby completing the fixation of the rotating plate 61 and ensuring that the rotating rod 52 will not rotate, thereby ensuring the stability of the subsequent winding work.

[0061] Specifically, the adjustment assembly includes a side plate 62, a second elastic member 63 and a swing rod 65. The side plate 62 is vertically fixedly installed on one side of a support plate 51. A slide groove is provided at the top of the side plate 62. A second elastic member 63 (also set as a spring here) is fixedly installed at the bottom of the slide groove. An insertion rod 64 is fixedly installed at one end of the second elastic member 63. A swing rod 65 is hinged on one side of the support plate 51. A fixing pin is fixedly installed on one side of the insertion rod 64. A movable groove is provided on the swing rod 65. The fixing pin is located in the movable groove. The size of the groove of the movable groove is larger than the cross-sectional size of the fixing pin. The fixing pin abuts against both the top and bottom surfaces of the inner wall of the movable groove.

[0062] The principle of the adjustment component driving the insertion rod 64 to move: when the insertion rod 64 needs to be separated from the notch 611, the swing rod 65 is moved downward ( Figure 8 The second elastic member 63 is used to move the rod 64 downwards, and the second elastic member 63 is used to move the rod 64 out of the notch 611. At this time, the handle 66 is held to drive the rotating rod 52 to rotate 180 degrees, so that the other notch 611 is directly above the rod 64. At this time, the swing rod 65 is released again, and the second elastic member 63 rebounds and drives the rod 64 to move upwards into the notch 611, thereby completing the fixation of the rotating plate 61. At the same time, when the rod 64 moves upwards, it will drive the swing rod 65 to rotate counterclockwise to reset.

[0063] like Figure 2 As shown, each first support block 531 is provided with a clamping member 533 for fixing the line on the side facing away from the tooling head 532;

[0064] The clamping piece 533 here is configured as a spring. After all the stators on a set of positioning tooling groups 53 are wound, when the positions of two positioning tooling groups 53 are flipped and swapped, the wire between the two stators rotationally symmetrically arranged on the rotating rod 52 will be fixed in the spring and in a stretched state. Therefore, when it is necessary to unload the stator after winding, when the wire between the two stators is cut in sequence (the precise wire cutting position: between cutting the spring and the unwound stator), it is ensured that the wire at one end of the wire head of each wound stator will not be loose, so that the wound wire on the stator will not spread out. When unloading the wound stator later, you can unload it with one hand and hold the wire head fixed by the clamping piece 533 with the other hand to take it out, so that the wire is always in a taut state. Later, the wire is manually wound around the stator to be fixed, so as to ensure that the wound wire on the stator will not spread out.

[0065] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
