Description

Technical Field

[0001] This application relates to the field of motor coils, and more particularly to a wire clamp for mass production of irregularly shaped motor coils. Background Technology

[0002] In the field of motor manufacturing, irregularly shaped coils are increasingly widely used in high-end equipment such as new energy vehicles and aerospace because they can adapt to complex iron core structures and improve electromagnetic conversion efficiency. As the core tooling for the mass production of irregularly shaped coils, the performance of the coil clamp directly determines the consistency of the coil, production efficiency and subsequent assembly accuracy. However, existing clamps have many limitations in adapting to the mass production of irregularly shaped coils and cannot meet the needs of industry development.

[0003] As a key component for positioning and assisting winding, the performance of the winding fixture directly affects production efficiency and material utilization. During the winding process, fluctuations in wire tension, such as increased tension when the wire is bent, can cause the coil to shift, resulting in problems such as uneven number of turns and loose arrangement of the coil, which in turn can lead to coil resistance deviation and unstable electromagnetic performance. Utility Model Content

[0004] To address the above problems, this application provides a wire clamp for mass manufacturing irregularly shaped coils of motors.

[0005] The present application provides a wire-gathering fixture for mass manufacturing irregularly shaped motor coils, which adopts the following technical solution:

[0006] A wire-gathering fixture for mass manufacturing irregularly shaped motor coils includes: a main rotating plate; six rotating rods, equidistantly arranged in a circular vertical pattern penetrating the main rotating plate; a rectangular plate mounted on the top surface of the rotating rods; two slots symmetrically mounted on the top surface of the rectangular plate; a winding mold core mounted between two of the slots, the winding mold core being configured to engage with and fit the slots; a fixing member mounted on one of the rectangular plates; six slots, equidistantly arranged in a circular pattern on the outer edge of the main rotating plate, with the six slots respectively located between two adjacent rotating rods; two sliding openings on the side walls of the slots; a cross block located between the two sliding openings; a vertical plate mounted on the top surface of the cross block; and a pneumatic shear mounted on the vertical plate.

[0007] Preferably, it further includes a threaded rod, which is vertically mounted at the center of the top surface of the main rotating plate via a bearing; a rotating ring, which is sleeved on the outer wall of the threaded rod; six second concave frames, which are equidistantly circumferentially mounted on the outer wall of the rotating ring; six first concave frames, which are respectively disposed on the top surface of each cross block; and a connecting plate, which is mounted at both ends in the first and second concave frames via shafts.

[0008] Preferably, it also includes a first motor mounted on the top surface of the main rotating plate; a second pulley sleeved on the output end of the first motor; the first pulley sleeved on the outer wall of the threaded rod; and the first pulley and the second pulley are connected by belt drive.

[0009] Preferably, the fastener includes a horizontal plate mounted on the side wall of the rectangular plate opposite to the threaded rod; two vertical rods mounted on the top surface of the horizontal plate; and a bayonet formed on the top surface of the vertical rods.

[0010] Preferably, a connecting plate is installed on the bottom surface of the horizontal plate, and both ends of the top surface of the connecting plate are connected to two vertical rods via shafts; a round rod is set at the center of the bottom surface of the connecting plate; and a rotating handle is sleeved on the outer wall of the round rod.

[0011] Preferably, it also includes a column installed on the bottom surface of the main rotating plate; a main support plate installed on the bottom surface of the column; a second motor installed on the bottom surface of the main support plate; and a main shaft installed at the output end of the second motor, the top end of the main shaft penetrating the column and extending upward to connect with the main rotating plate.

[0012] Preferably, it also includes a third motor, of which six are installed in a circular pattern at equal intervals on the bottom surface of the main rotating plate; each of the third motors corresponds one-to-one with each rotating rod, and the output end of the third motor is connected to the rotating rod.

[0013] Preferably, it also includes a limiting plate, which is installed on the top surface of the threaded rod.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. Six winding dies are circumferentially distributed, allowing for the simultaneous winding of multiple coils, enabling mass production and significantly improving manufacturing efficiency. A third motor independently drives the corresponding rotating rod, allowing for individual control of the winding speed and number of turns for each die according to requirements. This adapts to the differentiated production of coils of different specifications and shapes, offering high flexibility. The winding dies are designed to engage with two slots on the top surface of the rectangular plate. This structural design enables quick installation and removal of the dies. When it is necessary to change to coils of different specifications, simply remove the old die from the slots, replace it with a new die of the corresponding specification, and insert it into the slots. This significantly shortens changeover time, improves the equipment's versatility and production flexibility, and only one fixing piece is set on the rectangular plate, which can serve as a reference for the starting point of winding. The remaining dies are continuously wound with wire, adapting to the continuous production process of batch coils.

[0016] 2. The first motor drives the threaded rod to rotate, causing the rotating ring to move up and down. Through the connecting plate, a cross block is pulled to slide in the sliding groove, realizing the synchronous position adjustment of the six pneumatic shears. This cuts the coils wound in batches, matching the batch production rhythm and improving the cutting efficiency. The cross block slides in the sliding groove, driving the vertical plate and pneumatic shears to move along the slot, realizing the positional adaptation of the pneumatic shears and the wire, and adapting to the cutting needs of coils of different sizes.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a wire-gathering clamp for mass manufacturing irregularly shaped coils of motors, referring to... Figure 1 , Figure 2 and Figure 4It includes a main rotating plate 2, rotating rods 3, six equidistant, circumferentially vertically movable rods 3, a rectangular plate 22 fixedly installed on the top surface of the rotating rods 3, two slots 23 symmetrically fixedly installed on the top surface of the rectangular plate 22, and a winding mold core 4 installed between the two slots 23. The shape of the winding core perfectly matches the inner cavity shape of the irregular coil of the motor to be manufactured. As a reference skeleton during winding, it can ensure that the wire is arranged strictly according to the preset irregular trajectory during the winding process, avoiding coil deformation, thereby ensuring the dimensional accuracy and shape consistency of the coil, and meeting the precision requirements of motor assembly for the coil. The winding core 4 is set to be fitted with the slot 23. It also includes a third motor 17, of which there are six, which are equidistantly circumferentially detachably installed on the bottom surface of the main rotating plate 2. Each third motor 17 corresponds to each rotating rod 3. The output end of the third motor 17 is connected to the rotating rod 3. The third motor 17 can be a geared motor with a built-in reducer, which can output a large torque (1~5N・m) and a low speed (50~500rpm), suitable for thick wire diameter and high tension winding, such as model: Oriental Motor 5IK90GU-CF (power 90W, reduction ratio 1:10, output torque 1.2N・m).

[0025] Six winding mold cores 4 are distributed circumferentially, allowing for the simultaneous winding of multiple sets of coils, enabling mass production and significantly improving manufacturing efficiency. The third motor 17 independently drives the corresponding rotating rod 3, allowing for individual control of the winding speed and number of turns for each mold core according to requirements. This adapts to the differentiated production of coils of different specifications and shapes, offering high flexibility. The winding mold cores 4 are designed to engage with two slots 23 on the top surface of the rectangular plate 22. This structural design enables quick installation and removal of the mold cores. When it is necessary to change to coils of different specifications, simply remove the old mold core from the slot 23, replace it with a new mold core of the corresponding specification, and insert it into the slot 23. This significantly shortens the changeover time and improves the versatility and production flexibility of the equipment.

[0026] Reference Figure 2 It also includes a column 12, movably mounted on the bottom surface of the main rotating plate 2, a main support plate 1, fixedly mounted on the bottom surface of the column 12, a second motor 11, mounted on the bottom surface of the main support plate 1, and a spindle, mounted on the output end of the second motor 11. The top end of the spindle passes through the column 12 and extends upward to be fixedly connected to the main rotating plate 2. The second motor 11 can be a servo motor, supporting closed-loop control, with a positioning accuracy of ±0.01° and a smoothly adjustable speed (0~1500rpm). It can start and stop quickly and stop precisely at a preset angle, perfectly adapting to the step-by-step rotation requirements of the main rotating plate 2. For example, model: Yaskawa SGMAH-04AAA41 (power 400W, rated torque 1.27N・m, equipped with a 20-bit encoder, suitable for precise positioning under medium load).

[0027] The second motor 11 drives the main shaft to rotate the main rotating plate 2, which can transfer the completed mold core away and at the same time rotate the new empty mold core to the starting position of winding, realizing the automated flow of winding and reducing manual intervention. The main support plate 1 and the column 12 form a stable support structure to ensure the stability and accuracy of the main rotating plate 2 during rotation and avoid the impact of vibration on the coil winding quality.

[0028] Reference Figures 1-3 The main rotating plate 2 has six slots 13, which are equidistantly circumferentially arranged on the outer edge of the main rotating plate 2. The six slots 13 are respectively arranged between two adjacent rotating rods 3. Two sliding mouths 14 are opened on the two side walls of the slots 13. A cross block 15 is slidably arranged between the two sliding mouths 14. A vertical plate 5 is installed on the top surface of the cross block 15. A pneumatic shear 10 is installed on the vertical plate 5. The pneumatic shear 10 can be a small pneumatic shear (fine wire diameter coil, ≤1.2mm). It is characterized by its small size, moderate shearing force (50~150N), and fast response speed (single shearing time ≤0.1 seconds). It is suitable for installation on the vertical plate 5 to avoid interference with the winding mold core 4. For example, the model is CHELIC AS-10 (shearing range Φ0.3~1.2mm, cutter head angle 90°, weight only 120g, suitable for precision shearing).

[0029] It also includes a threaded rod 6, vertically mounted on the center of the top surface of the main rotating plate 2 via a bearing (usually a thrust ball bearing, such as model 51105), mounted on the contact surface between the threaded rod 6 and the main rotating plate 2 to bear the axial pressure generated when the threaded rod 6 rotates (especially the thrust when the rotating ring 21 moves up and down), a limiting plate fixedly mounted on the top surface of the threaded rod 6, a rotating ring 21 threadedly fitted onto the outer wall of the threaded rod 6, six second concave frames 20 equidistantly circumferentially fixedly mounted on the outer wall of the rotating ring 21, six first concave frames 19 respectively set on the top surface of each cross block 15, a connecting plate 18, both ends of which are movably mounted within the first concave frames 19 and the second concave frames 20 via shafts, a first motor 8 mounted on the top surface of the main rotating plate 2, a second pulley 9 fitted onto the output end of the first motor 8, a first pulley 7 fitted onto the outer wall of the threaded rod 6, and a first pulley 7 between the second pulley 9 and the first pulley 8. The first motor 8 is connected via belt drive. It can be a small servo motor with a wide controllable speed range (0~3000rpm), stable torque output, and support for precise speed control (facilitating adjustment of the lifting speed of the rotating ring 21). It is suitable for the fine adjustment requirements of the pneumatic shear 10 position, such as the Delta ECMA-C20604RS (400W power, rated torque 1.27N・m, equipped with a 17-bit encoder, supports pulse control, and has high adjustment accuracy). The core component parameters are matched. The output shaft of the first motor 8 is connected to the second pulley 9 by a key or a tight fit to provide rotational power. The diameter of the second pulley 9 is usually smaller than that of the first pulley 7. The motor power is transmitted to the first pulley 7 through the belt. The first pulley 7 is sleeved on the outer wall of the threaded rod 6, converting the belt power into the rotational motion of the threaded rod 6. The belt is mostly a polyurethane synchronous belt (such as H-type or XL-type), and the belt teeth mesh with the pulley teeth to avoid slippage.

[0030] The first motor 8 drives the threaded rod 6 to rotate, causing the rotating ring 21 to move up and down. Through the connecting plate 18, the six cross blocks 15 are pulled to slide within the sliding opening 14, realizing the synchronous position adjustment of the six pneumatic shears 10. This allows for the cutting of coils wound in batches, matching the batch production rhythm and improving cutting efficiency. The sliding of the cross blocks 15 within the sliding opening 14 drives the vertical plate 5 and the pneumatic shears 10 to move along the slot 13, achieving positional adaptation between the pneumatic shears 10 and the wire, and adapting to the cutting requirements of coils of different sizes.

[0031] Reference Figure 1 and Figure 5The fastener 24 is disposed on one of the rectangular plates 22. The fastener 24 includes a horizontal plate 241, which is fixedly installed on the side wall of the rectangular plate 22 opposite to the threaded rod 6; two vertical rods 242, which are movably installed on the top surface of the horizontal plate 241; a bayonet 243, which is opened on the top surface of the vertical rods 242; a connecting plate 244, which is movably installed on the bottom surface of the horizontal plate 241; both ends of the top surface of the connecting plate 244 are fixedly connected to the two vertical rods 242 through shafts; a round rod 245, which is rotatably disposed at the center of the bottom surface of the connecting plate 244 and is rotatably connected to the horizontal plate 241; and a handle 246, which is fixedly sleeved on the outer wall of the round rod 245.

[0032] At the beginning of winding, rotating the handle 246 drives the connecting plate 244 through the round rod 245, so that the clamps 243 of the two vertical rods 242 clamp the wire end, preventing the wire end from loosening during the winding process and ensuring the tightness and consistency of the coil winding. The clamping structure of the clamp 243 is easy to operate (adjusted by the handle 246), which facilitates quick fixing or loosening of the wire end and improves the efficiency of the winding preparation stage. Only a fixing piece 24 is set on a rectangular plate 22, which can be used as a reference for the starting point of winding. The remaining cores are continuously wound with wire, which is suitable for the continuous production process of batch coils.

[0033] The implementation principle of a wire-gathering clamp for mass manufacturing irregularly shaped motor coils in this application embodiment is as follows: Based on the specifications of the irregularly shaped coil to be produced, a winding mold core 4 of corresponding shape is selected. It is then clamped onto the rectangular plate 22 at the top of the six rotating rods 3 via a slot 23, achieving rapid positioning and installation of the mold core. The starting end of the winding wire is placed at the fixing part 24 of one of the rectangular plates 22. Rotating the handle 246 drives the connecting plate 244 via the round rod 245, causing the clamps 243 of the two vertical rods 242 to clamp the wire end, preventing the wire from loosening during winding. Subsequently, the third motor 17 at the starting position is started separately, driving the winding mold core 4 to rotate, and the wire is fed externally. With the cooperation of the winding mechanism, the coil is wound along the irregular contour of the winding mold core 4 to form a coil prototype. The second motor 11 drives the main shaft to rotate the main rotating plate 2, which can transfer the completed mold core away and at the same time rotate the new empty mold core to the winding start position, realizing the automated flow of winding. Finally, the first motor 8 is started, which drives the threaded rod 6 to rotate through the transmission of the second pulley 9, belt, and first pulley 7, so that the rotating ring 21 sleeved on the threaded rod moves up and down. The rotating ring 21 pulls the cross block 15 to slide in the slide 14 through the 6 connecting plates 18, and simultaneously adjusts the movement position of the pneumatic shears 10 on the six vertical plates 5 to ensure that the shearing edge is accurately aligned with the position of the coil wire.
