The second clamping plate is slidably connected to the guide rod, and the rod length direction of the guide rod is consistent with the axial length direction of the rotating rod, so that the displacement path of the second clamping plate on the rotating rod along the guide rod is limited, and the situation that when a worker pulls the second clamping plate, the second clamping plate deviates from the rotating rod, and consequently the pulling result of the armature coil does not conform to a target is avoided. And the drawing efficiency of the armature coil is further improved.

[0002] An armature coil is a coil group wound and connected according to certain rules, and it is one of the main components for realizing the conversion of mechanical and electrical energy in an electric machine.

[0003] The armature coils of small DC motors are generally frame-type coils. During the small-scale manufacturing or repair of motors, it is necessary to produce armature coils at low cost. In order to ensure that the coils are perfectly fitted into the iron core, it is necessary to distinguish between the upper and lower wires of the coils. Traditional production mostly uses manual operations, which have the disadvantages of low production efficiency, high labor intensity, and poor production accuracy. Although there are some armature coil forming devices on the market, their prices are relatively high, resulting in an increase in production costs and being not conducive to wide promotion and use.

[0034] Combine Figures 1-7As shown in the figure, an armature coil drawing tooling includes a bracket 1, a first clamping plate 10, a limiting plate 50, a rotating rod 30, a second clamping plate 20, and a guiding rod 40. The limiting plate 50 with a vertical plate surface is fixedly connected to the side of the vertically arranged bracket 1. The first clamping plate 10 is slidably arranged on the limiting plate 50 and can displace along the height direction of the bracket 1 on the limiting plate 50. One end of the rotating rod 30 is rotatably connected to the side of the bracket 1 away from the first clamping plate 10, and the other end of the rotating rod 30 extends horizontally and can approach or move away from the top of the bracket 1. One end of the guiding rod 40 is fixedly connected to the rotating rod 30, and the other end extends horizontally along the axial direction of the rotating rod 30. The second clamping plate 20 is slidably arranged on the rod body of the guiding rod 40 and can approach or move away from the bracket 1 horizontally along the axial direction of the guiding rod 40.

[0035] The armature coil drawing tooling in this application is composed of a bracket 1, a first clamping plate 10, a second clamping plate 20, a rotating rod 30, a limiting plate 50, and a guiding rod 40. One section of the armature coil in this application is fixedly connected to the first clamping plate 10, and the other section of the armature coil is fixedly connected to the second clamping plate 20. The first clamping plate 10 is slidably connected to the bracket 1, and the first clamping plate 10 is constrained on the limiting plate 50 with a vertical plate surface. The staff can adjust the relative position between the first clamping plate 10 and the limiting plate 50 according to the predetermined shape of the armature coil to perform the drawing operation of armature coils of different specifications. The second clamping plate 20 is slidably connected to the guiding rod 40, and the rod length direction of the guiding rod 40 is the same as the axial length direction of the rotating rod 30 to limit the displacement path of the second clamping plate 20 along the guiding rod 40 on the rotating rod 30, avoiding the deviation of the second clamping plate 20 from the rotating rod 30 when the staff pulls the second clamping plate 20, resulting in the drawing result of the armature coil not matching the target, thereby improving the drawing efficiency of the armature coil.

[0036] The first clamping plate 10 includes a first upper clamping plate 11 and a first lower clamping plate 12. The first lower clamping plate 12 is vertically arranged, and the bottom surface of the first lower clamping plate 12 is slidably matched with the side surface of the limiting plate 50. The first upper clamping plate 11 is buckled above the first lower clamping plate 12 and is screwed to the first lower clamping plate 11.

[0037] In the above solution, the first clamping plate 10 in this application is composed of a first upper clamping plate 11 and a first lower clamping plate 12. The second upper clamping plate 21 and the second lower clamping plate 22 are fixed by means of threaded connection. The purpose of such a setting is to facilitate the installation and disassembly of the second clamping plate 20 and at the same time facilitate the staff to constrain the armature coil on the first clamping plate 10. When the armature coil starts or completes the drawing operation, the first upper clamping plate 11 and the first lower clamping plate 12 can be directly separated, and then the armature coil can be put in or taken out.

[0038] On the bottom surface of the first upper clamping plate 11, a first light groove 111 is provided along its thickness direction. On the top surface of the first lower clamping plate 12, a second light groove 121 is opened along its thickness direction. The openings of the first light groove 111 and the second light groove 121 face each other, and a space for constraining the coil can be formed. A section of the armature coil in this application is constrained on the first clamping plate 10. The settings of the first light groove 111 and the second light groove 121 can not only well constrain the armature coil, but also ensure that a section of the armature coil can be stably constrained on the first clamping plate 10 during the process of the staff pulling the rotating rod 30 to deform the armature coil.

[0039] In the middle of the rotating rod 30, a groove 32 is opened upward along its thickness direction. The groove length direction of the groove 32 is the same as the rod length direction of the rotating rod 30. The groove width of the groove 32 is the same as the width of the second lower clamping plate 22. One end of the guiding rod 40 is fixedly connected to the groove wall on the side of the groove 32 close to the bracket 1 and is spaced from the bottom of the groove 32.

[0040] This application adopts an embedded form to constrain the guiding rod 40 inside the rotating rod 30, so as to prevent the second clamping plate 20 from deviating when the rotating rod 30 moves closer to or away from the top of the bracket 1, and to limit the displacement path of the second clamping plate 20 sliding on the rotating rod 30. The groove width of the groove 32 being the same as the width of the second lower clamping plate 22 further improves the stable connection between the second clamping plate 20 and the rotating rod 30.

[0041] The second clamping plate 20 includes a second upper clamping plate 21 and a second lower clamping plate 22; the second lower clamping plate 22 is horizontally arranged above the rotating rod 30. The bottom surface of the second lower clamping plate 22 is in sliding fit with the top surface of the rotating rod 30. The second upper clamping plate 21 is arranged above the second lower clamping plate 22 and is screwed to the second lower clamping plate 22.

[0042] The second clamping plate 20 in this application is composed of a second upper clamping plate 21 and a second lower clamping plate 22. The second upper clamping plate 21 and the second lower clamping plate 22 are fixed by means of threaded connection. The purpose of this setting is to facilitate the installation and disassembly of the second clamping plate 20 and at the same time facilitate the staff to constrain the armature coil on the second clamping plate 20. When the armature coil starts or completes the drawing operation, the second upper clamping plate 21 and the second lower clamping plate 22 can be directly separated, and then the armature coil can be placed or taken out, simplifying the installation and disassembly work of the armature coil and further improving the drawing efficiency of the armature coil.

[0043] On the bottom surface of the second upper clamping plate 21, a third light groove 211 is provided along its thickness direction. On the top surface of the first lower clamping plate 12, a fourth light groove 221 is opened along its thickness direction. The openings of the third light groove 211 and the fourth light groove 221 face each other, and a space for constraining the coil can be formed. A section of the armature coil in this application is constrained on the second clamping plate 20. The settings of the third light groove 211 and the fourth light groove 221 can not only well constrain the armature coil, but also prevent the surface of the coil from rubbing against the groove wall during the shaping of the armature coil, so as to ensure the integrity of the surface of the armature coil.

[0044] The embodiment of this application further includes a sliding plate 41. The sliding plate 41 is arranged between the second lower clamping plate 22 and the guide rod 40. The upper end of the sliding plate 41 is fixedly connected to the lower end surface of the second lower clamping plate 22. The side surface of the sliding plate 41 is slidably matched with the groove wall of the groove 32. A light hole for the guide rod 40 to pass through is horizontally penetrated along the plate width direction at the lower end of the sliding plate 41, and the hole wall of the light hole is slidably connected to the peripheral surface of the guide rod 40.

[0045] In the above solution, the setting of the sliding plate 41 is to avoid the direct contact between the second lower clamping plate 22 and the guide rod 40, ensure the stable connection between the second lower clamping plate 22 and the guide rod 40, and facilitate the sliding connection between the second lower clamping plate 22 and the guide rod 40. The setting of the sliding plate 41 also improves the structural strength of the second lower clamping plate 22, and avoids the interaction between the stress generated when the armature coil deforms and the second lower clamping plate 22 when the staff pulls the armature coil, resulting in the fracture or damage of the second lower clamping plate 22.

[0046] On the side of the limiting plate 50 close to the first lower clamping plate 12, a screw hole 501 is opened upward along its plate thickness direction. A bolt 13 is fixedly connected to the middle of the first lower clamping plate 12. One end of the bolt 13 extends into the screw hole 501 and fixes the first lower clamping plate 12 on the limiting plate 50.

[0047] In the above solution, multiple screw holes 501 can be provided, and the multiple screw holes 501 can be evenly arranged on the plate surface of the limiting plate 50, so as to facilitate the staff to adjust the relative position between the first lower clamping plate 12 and the limiting plate 50 according to the required target shape of the armature coil, and facilitate the shaping operation of armature coils of different specifications. The bolt 13 passes through the first lower clamping plate 12 and extends into the screw hole 501 to ensure the stable connection between the first lower clamping plate 12 and the limiting plate 50, and prevent the first clamping plate 10 from falling off the limiting plate 50 when the staff pulls the second clamping plate 20.

[0048] To facilitate the staff to pull the second clamping plate 20 to slide on the guide rod 40, ear plates 23 extend horizontally outward from both ends of the plate width of the second lower clamping plate 22 from its end surface. The thickness of the ear plates 23 is less than the thickness of the second lower clamping plate 22. The purpose of the thickness of the ear plates 23 being less than the thickness of the second lower clamping plate 22 is to facilitate the staff to hold while avoiding the ear plates 23 interfering with the displacement of the second lower clamping plate 22 on the guide rod 40.

[0049] A bearing seat 2 is symmetrically arranged in the middle of the bracket 1. One end of the rotating rod 30 close to the bracket 1 symmetrically extends along its radial direction with a rotating shaft 31. The outer wall of the rotating shaft 31 is rotatably connected to the inner wall of the bearing seat 2. The purpose of this setting is to facilitate manual pulling of the rotating rod 30. The rotating rod 30 rotates along the rotating shaft 31 from the bearing seat 2, so as to facilitate the pulling and forming operation of the armature coil.

[0050] The bottoms of the two bearing seats 2 are threadedly connected to one side surface of the bracket 1 close to the rotating rod 30, and the axes of the two bearing seats 2 are at the same horizontal height.

[0051] The various embodiments in this specification are described in a progressive manner. For the same or similar parts between the various embodiments, reference can be made to each other. The key points of each embodiment are the differences from other embodiments.

[0052] The above embodiments are only used to illustrate the technical solutions of the present application, rather than limiting the present application; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the present application.
