Description

Technical Field

[0001] The utility model relates to the field of armature coil bending tooling, in particular to an armature coil bending tooling. Background Art

[0002] The armature coil, as a key component in the motor, is composed of a coil wound by a wire. It realizes the conversion between mechanical energy and electrical energy by interacting with the magnetic field. It is located in the rotor or stator part of the motor, and varies according to the type of motor and the working principle. The armature coil is not only responsible for generating torque to make the motor rotate, but also determines the positioning of the rotor and controls the running speed, direction and efficiency of the motor by changing the direction of the current. When bending the end of the coil, the existing armature coil bending tooling mostly follows the following process: first, the coil is placed in the area to be bent, and then the electric push rod and bending mechanism are controlled to bend the end of the coil. However, there is a problem in the bending process. Specifically, the bent coil is easily stuck with the external placement table due to the deformation of the coil end, which makes it more laborious for the operator to replace the next coil, and the interval is long, thereby reducing the bending efficiency of the coil. Utility Model Content

[0003] Based on this, the purpose of the present utility model is to provide an armature coil bending tool to solve the technical problem that in the existing coil bending process, the processing interval between adjacent coils is long due to the engagement of the workpiece with the external placement table, thereby reducing the bending efficiency.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an armature coil bending tool, comprising a base plate and a coil, a top plate is arranged above the base plate and supported by a support rod, a rotating mechanism is arranged on the top of the base plate, the rotating mechanism comprises a rotating plate, the rotating plate is rotatably connected to the base plate through a rotating shaft, a first support platform and a second support platform are respectively arranged on both sides of the top of the rotating plate, a limiting column is arranged on the top of the first support platform and the second support platform, an electric push rod is arranged on the top of the top plate, and a bending mechanism is arranged at the telescopic end of the electric push rod.

[0005] By adopting the above technical solution, a first support platform and a second support platform are set up, and a double-station form is cleverly formed, so that the coils that have been bent can be quickly moved to the outer position through the rotation of the rotating shaft, thereby facilitating timely collection and processing by operators. This processing method effectively reduces the waiting time and space occupancy of the coils during the processing process, and improves the overall work efficiency.

[0006] Furthermore, both sides of the bottom surface of the rotating plate are provided with empty grooves, and the top surface of the bottom plate and the position opposite to the empty grooves are provided with support blocks for providing support force for the rotating plate.

[0007] By adopting the above technical solution, the support block can be accurately inserted into the empty slot, providing a solid support force for the turn plate, ensuring the stability of the turn plate during rotation and carrying the coil, and effectively preventing the turn plate from shaking or tilting due to uneven force or external interference, thereby protecting the precise position and shape of the coil.

[0008] Furthermore, a slope is formed on one side of the support block to provide guidance for the rotating plate.

[0009] By adopting the above technical solution, during the rotation of the turn plate, the inclined surface can effectively guide the turn plate to rotate smoothly along a predetermined path, ensuring the accuracy and stability of the rotation, reducing the deviation or shaking that may occur during the rotation of the turn plate, thereby protecting the precise position and shape of the coil and improving the processing quality.

[0010] Furthermore, one side of the base plate is rotatably connected to a limit plate via a torsion shaft, so as to limit the rotation position of the rotating plate.

[0011] By adopting the above technical solution, the limit plate can effectively limit the rotation position of the turn plate, ensuring that the turn plate rotates within a predetermined angle range, thereby avoiding excessive rotation or misalignment. This limiting effect not only improves the accuracy and stability of the turn plate rotation, but also effectively protects the precise position and shape of the coil during the processing process, further improving the processing quality.

[0012] Furthermore, the bending mechanism includes a limit frame, and limit plates are provided on both sides of the bottom of the limit frame, and the limit frame and the two limit plates are in a "U"-shaped structure.

[0013] By adopting the above technical solution, this "U"-shaped structure provides a precise limiting space for the coil, which can effectively fix the position of the coil during the bending process to prevent it from shifting or shaking, thereby ensuring the accuracy and consistency of the bending.

[0014] Furthermore, the outer side of the limit plate is slidably connected to a pressure plate, a pressure spring is arranged between the pressure plate and the limit frame, a guide surface is formed at the lower inner side of the limit plate, and a roller is rotatably arranged on one side of the guide surface to reduce the friction damage of the limit plate to the coil.

[0015] By adopting the above technical solution, the combination of the pressure plate and the pressure spring can provide a stable pressure for the coil, ensuring that the coil maintains a fixed position during the bending process, thereby improving the accuracy and consistency of the bending.

[0016] Furthermore, the electric push rod is electrically connected to an external power supply through a controller, and the bending mechanism is respectively positioned opposite to the first support platform and the second support platform.

[0017] By adopting the above technical solution, the connection between the electric push rod and the external power supply ensures its stable working state, so that the bending operation can be carried out continuously and efficiently.

[0018] In summary, the present invention has the following beneficial effects:

[0019] 1. The utility model provides a first support platform and a second support platform to form a double-station form, so that the bent coils can be quickly rotated to the outside through the rotating shaft for easy collection and processing, thereby effectively reducing the waiting time and space occupied by the coils during processing. At the same time, this double-station form also allows the next bending operation to be performed immediately at the location of the unbent coil without waiting for the previous coil to be processed. In this way, the interval time between adjacent processed coils is significantly shortened, thereby greatly improving the bending efficiency of the coils, making the entire processing process smoother and more efficient.

[0020] 2. The utility model provides a support block, which accurately guides the turn plate by the inclined surface, ensuring that the turn plate can rotate smoothly along the predetermined path. This guiding effect not only improves the accuracy and stability of the turn plate rotation, but also effectively prevents the turn plate from deviating or shaking during the rotation process. At the same time, as the turn plate continues to rotate, the support block will gradually fit into the empty slot. This fitting effect further enhances the support stability of the turn plate, the first support platform and the second support platform for the coil. This stable support structure effectively protects the precise position and shape of the coil during the processing process, thereby significantly improving the bending processing stability of the coil and ensuring the consistency and reliability of the processing quality.

[0029] The following describes an embodiment of the present invention based on its overall structure.

[0030] Example 1:

[0031] An armature coil bending tool, such as Figures 1-4As shown, it includes a bottom plate 1 and a coil 7, a top plate 3 is provided above the bottom plate 1, and is supported by a support rod 2, a rotating mechanism 6 is provided on the top of the bottom plate 1, and the rotating mechanism 6 includes a rotating plate 601, and the rotating plate 601 is rotatably connected to the bottom plate 1 through a rotating shaft 607, and a first support platform 602 and a second support platform 603 are provided on both sides of the top of the rotating plate 601, respectively, and a limiting column 604 is provided on the top of the first support platform 602 and the second support platform 603, an electric push rod 4 is provided on the top of the top plate 3, and a bending mechanism 5 is provided at the telescopic end of the electric push rod 4, a first support platform 602 and a second support platform 603 are provided, and a double-station form is cleverly formed, so that it has been The bent coil 7 can be quickly moved to the outer position by rotating the rotating shaft 607, so that the operator can collect and process it in time. This processing method effectively reduces the waiting time and space occupied by the coil during the processing, and improves the overall work efficiency. At the same time, it also ensures that the unbent coil 7 can be immediately rotated to the bottom of the bending mechanism 5 for the next bending operation without waiting for the previous coil 7 to be processed. This seamless working method greatly reduces the interval time between adjacent processed coils 7, which significantly improves the bending efficiency of the coil and further enhances the smoothness and efficiency of the entire processing process.

[0032] Example 2:

[0033] See Figure 4 , there are empty slots 605 on both sides of the bottom surface of the rotating plate 601, and support blocks 606 are provided on the top surface of the bottom plate 1 and at the position opposite to the empty slots 605, which are used to provide support for the rotating plate 601. The support blocks 606 can be accurately inserted into the empty slots 605, providing a stable support force for the rotating plate 601, ensuring the stability of the rotating plate 601 during rotation and carrying the coil 7, and effectively preventing the rotating plate 601 from shaking or tilting due to uneven force or external interference, thereby protecting the precise position and shape of the coil 7. At the same time, the combination of the support blocks 606 and the empty slots 605 also plays a guiding role, making the rotating plate 601 smoother and smoother when rotating, reducing resistance and wear during rotation, further extending the service life of the tooling and improving its reliability.

[0034] See Figure 2 、 Figure 4A slope 608 is formed on one side of the support block 606 to provide guidance for the rotating plate 601. During the rotation of the rotating plate 601, the slope 608 can effectively guide the rotating plate 601 to rotate smoothly along a predetermined path, ensuring the accuracy and stability of the rotation, and reducing the deviation or shaking that may occur when the rotating plate 601 rotates, thereby protecting the precise position and shape of the coil 7 and improving the processing quality. At the same time, the guiding effect of the slope 608 also makes the rotating plate 601 smoother when rotating, reducing the resistance and wear during the rotation process, which not only extends the service life of the tooling, but also improves its overall performance and reliability.

[0035] See Figure 2 、 Figure 4 One side of the base plate 1 is rotatably connected to a limiting plate 609 through a torsion shaft 610, which is used to limit the rotation position of the rotating plate 601. The limiting plate 609 can effectively limit the rotation position of the rotating plate 601, ensuring that the rotating plate 601 rotates within a predetermined angle range, thereby avoiding excessive rotation or misalignment. This limiting effect not only improves the accuracy and stability of the rotation of the rotating plate 601, but also effectively protects the precise position and shape of the coil 7 during the processing process, further improving the processing quality. At the same time, the setting of the torsion shaft 610 enables the limiting plate 609 to have a certain buffering and regulating effect when limiting the rotation of the rotating plate 601, thereby reducing the impact and wear during the rotation process.

[0036] See Figure 1 、 Figure 3 The bending mechanism 5 includes a limit frame 501, and limit plates 502 are provided on both sides of the bottom of the limit frame 501, and the limit frame 501 and the two limit plates 502 are in a "U" shape. This "U" shape structure provides a precise limit space for the coil 7, which can effectively fix the position of the coil 7 during the bending process to prevent it from offsetting or shaking, thereby ensuring the accuracy and consistency of the bending. At the same time, the sturdy structure of the limit frame 501 and the limit plate 502 also plays a protective role, preventing the coil 7 from being unnecessary squeezed or deformed during bending, further improving the processing quality and the overall performance of the coil 7.

[0037] See Figure 1 、 Figure 3The outer side of the limit plate 502 is slidably connected to a pressure plate 503, and a pressure spring 504 is arranged between the pressure plate 503 and the limit frame 501. A guide surface 505 is formed on the lower inner side of the limit plate 502, and a roller 506 is rotatably arranged on one side of the guide surface 505 to reduce the friction damage of the limit plate 502 to the coil 7. The combination of the pressure plate 503 and the pressure spring 504 can provide a stable pressure for the coil 7, ensuring that the coil 7 maintains a fixed position during the bending process, thereby improving the accuracy and consistency of the bending. At the same time, the setting of the guide surface 505 and the roller 506 greatly reduces the friction damage of the limit plate 502 to the coil 7, reduces the wear and deformation of the coil 7 during the processing, and further improves the processing quality and the overall performance of the coil 7.

[0038] See Figure 1 、 Figure 2 、 Figure 3 The electric push rod 4 is electrically connected to the external power supply through the controller, and the bending mechanism 5 is respectively opposite to the first support platform 602 and the second support platform 603. The connection between the electric push rod 4 and the external power supply ensures its stable working state, so that the bending operation can be carried out continuously and efficiently. At the same time, the relative position setting of the bending mechanism 5 and the first support platform 602 and the second support platform 603 enables the coil 7 to be quickly transferred after the bending is completed, and the unbent coil 7 can immediately enter the bending position, which greatly improves the work efficiency and shortens the processing interval between adjacent coils, thereby significantly improving the bending efficiency of the coil.

[0039] The implementation principle of the present invention is as follows: when the end of the coil 7 needs to be bent, first, the unbent coil 7 is placed on the outer side of the upper limit column 604 of the first support platform 602, and then, the torsion of the torsion shaft 610 is overcome to rotate the limit plate 609 to eliminate the limitation of the limit plate 609 on the rotating plate 601, and then, the rotating plate 601 is rotated by the rotating shaft 607 until the first support platform 602 and the bending mechanism 5 are relative to each other. During the rotation of the rotating plate 601, the rotating plate 601 is guided by the inclined surface 608 until the support block 606 is matched with the empty slot 605, thereby improving the support stability of the rotating plate 601, the first support platform 602 and the second support platform 603 on the coil 7, and improving the bending processing stability of the coil 7, and then, the bending mechanism of the telescopic end of the electric push rod 4 is controlled by the external controller. 5 moves downward, and the limiting plate 502 is used to abut the end of the outer side of the coil 7, causing the end to gradually bend. As it is gradually pressed downward, the pressing plate 503 is used to press the top surface of the coil 7, further improving the stability of the bending operation of the coil 7. Afterwards, the limiting frame 501 and the limiting plate 502 are compressed by the pressure spring 504 to continuously move downward, thereby achieving the bending processing of the ends on both sides of the coil 7. During the above operation, a double-station form is formed by arranging the first support platform 602 and the second support platform 603. The bent coil 7 can be rotated to the outside through the rotating shaft 607 and collected for processing. At the same time, the unbent coil 7 is rotated to the bottom of the bending mechanism 5 to perform the bending operation, thereby reducing the interval time between adjacent processed coils 7 and improving the bending efficiency of the coil 7.

[0040] like Figure 1 As shown, the coil 7 on one side of the bottom plate 1 is the coil 7 that has not been bent, and the coil 7 placed on the first support platform 602 and the second support platform 603 is the coil 7 that has been processed.
