Detailed Embodiments

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] Please refer to Figure 1 , please refer to Figures 1-6 , which is a core shaping device disclosed in the embodiments of the present invention, including a workbench 1. A fixedly installed shaping component 2 and a slidably installed detection component 3 are arranged on the upper end of the workbench 1. The detection component 3 is connected with a sliding drive. The shaping component 2 includes a slide plate 21. The slide plate 21 is slidably installed on the workbench 1. There are two symmetrically arranged slide plates 21. The slide plate 21 is connected with a sliding drive. Shaping parts 22 are fixedly installed on both slide plates 21. A core seat 23 is rotatably installed on the workbench 1. The core seat 23 is located at the symmetric center of the two slide plates 21. The core seat 23 is connected with a rotation driving member. The detection component 3 includes an upper pressing die 31. The upper pressing die 31 is coaxially arranged with the core seat 23. A plurality of detection sensors 32 are circumferentially and arrayedly installed on the outer side of the upper pressing die 31. The detection ends of the detection sensors 32 face the core seat 23.

[0043] Specifically, symmetrically arranged slide plates 21 are arranged on the upper end of the workbench 1. The core seat 23 is installed at the symmetric center of the two slide plates 21. When the core is installed on the core seat 23, the two slide plates 21 slide towards each other under the drive of the sliding drive, and the core is clamped by the shaping parts 22 to perform circumferential shaping on the core. The detection component 3 is coaxially arranged with the core seat 23. After the circumferential shaping is completed, the detection component 3 approaches the core on the core seat 23 under the drive of the sliding drive, and the upper pressing die 31 presses the core to perform axial shaping on the core. After the axial shaping of the upper pressing die 31 is completed, the upper pressing die 31 rises, and the detection sensors 32 detect the end face of the core to ensure the axial shaping effect.

[0044] In this way, the circumferential and axial shaping of the core is performed through the shaping parts 22 and the upper pressing die 31 to ensure the concentricity and perpendicularity of the core, and the detection sensors 32 are used for detection to make the shape of the core regular and facilitate the subsequent processes.

[0045] In some feasible ways, please refer to Figure 1 , the workbench 1 is in the shape of a rectangular body frame. To facilitate the installation of the detection component 3, a support seat 101 is fixedly installed on the upper end of the workbench 1.

The two output ends of the bidirectional lead screw 211 are respectively fixedly connected to the two sliding plates 21. The bidirectional lead screw 211 is connected with an adjustment motor 212. When the adjustment motor 212 drives the bidirectional lead screw 211 to rotate, the two sliding plates 21 move towards or away from each other along the slide rails. To facilitate the automatic control of the sliding plate 21, sensors such as proximity switches or infrared sensors that can identify the passing of the sliding plate 21 are arranged at corresponding positions of the slide rails. The shaping part 22 can be set as a model block adapted to the core to be detected. The circumferential shaping is completed by squeezing the core through the shaping part 22. To facilitate the installation of the core seat 23, please refer to Figure 2 and Figure 3 , the rotation drive member structure of the core seat 23 includes a through groove opened in the middle of the top plate 201. An installation plate 202 is fixedly mounted below the through groove. A bearing is fixedly mounted at the upper end of the installation plate 202. A driving disc 203 is installed in the bearing. The driving disc 203 is fixedly connected with the core seat 23. The core seat 23 is an installation mold set according to the shape of the core. A shaping motor 204 is fixedly mounted at the bottom of the installation plate 202. The output end of the shaping motor 204 passes through the installation plate 202 and is fixedly connected to the driving disc 203.

[0047] The upper pressing die 31 is an adapted mold set according to the shape of the core to be shaped. For ease of use, in this embodiment, please refer to Figure 6 , the upper pressing die 31 includes an outer ring 311. An inner integral ring 312 is fixedly arranged inside the outer ring 311. The inner integral ring 312 is bolted with an arc-shaped pressing die 313. The inner integral ring 312 is provided with a three-phase terminal groove 314. Among them, the arc-shaped pressing die 313 is annular. According to the size of the arc-shaped pressing die 313 adapted to the core, the three-phase terminal groove 314 is a shaping component for the core wiring terminal and can also be set according to the actual installation position of the core.

The lower ends of the shaping outer cylinders 222 are rotatably installed on the sliding plate 21, and the shaping outer cylinders 222 are arranged along the outer contour of the iron core to be detected.

[0049] Overall, by arranging a plurality of shaping outer cylinders 222 and cooperating with the rotation of the iron core seat 23, the iron core seat 23 is shaped by rotation, which is more conducive to maintaining the overall circular contour of the iron core.

[0050] In some feasible ways, a plurality of rectangular plates are bolted to the upper end of the sliding plate 21. Columns 221 in the shape of cylinders are fixedly installed on the rectangular plates. Rectangular plates are installed at the upper ends of the columns 221, and the shaping outer cylinders 222 are rotatably installed between the two rectangular plates.

[0051] As another specific embodiment of the iron core shaping device provided by the application, please refer to Figure 5 , the detection sensor 32 is a contact sensor.

An avoidance groove 315 is opened on the side wall of the upper pressing die 31. During use, the probe part 323 protrudes from the avoidance groove 315.

[0052] It should be understood that by arranging the slidable part of the detection sensor 32, the interference between the upper pressing die 31 and the detection sensor 32 during operation is reduced. After the axial shaping of the upper pressing die 31 is completed, the upper pressing die 31 rises, and the detection sensor 32 moves down into the avoidance groove 315 to contact the end face of the iron core for detection.

[0053] In some feasible ways, the detection movable plate 321 is an annular plate sleeved outside the electric cylinder joint 302. The sliding drive can be selected as a cylinder.

A transfer assembly 7 is slidably installed on the cross frame 6. The transfer assembly 7 is connected with a sliding drive. The transfer assembly 7 is used to transfer the iron core between the tray 51 and the iron core seat 23.

[0055] It should be understood that by setting the base 4, the tray 51 and the transfer component 7, in cooperation with the detection sensor 32 and the shaping part 22, it is convenient to automatically complete the core detection.

[0056] In some feasible ways, the base 4 is plate-shaped, and a plurality of support feet are provided at the bottom of the base 4. The wire body 5 is a chain conveyor mechanism in the mechanical structure. The tray 51 is rectangular, the cross-frame 6 is beam-shaped, and a linear module 701 for driving the transfer component 7 is installed on the cross-frame 6. The linear module 701 can be selected as a linear drive mechanism such as a lead screw mechanism or an electric push rod that can reciprocate. The output end of the linear module 701 is fixedly connected to the transfer component 7, and the transfer component 7 is in the shape of a mechanical claw. When the core is placed on the tray 51, the tray 51 runs to the position of the transfer component 7 along with the wire body 5. The transfer component 7 grabs the core through the mechanical claw, and the linear module 701 drives the transfer component 7 to transfer the core to the core seat 23. After the shaping and detection are completed, the core is transferred back to the tray 51 through the transfer component 7.

[0057] In some feasible ways, please refer to Figure 7 and Figure 8 , the transfer component 7 includes a module slide plate 71. The module slide plate 71 is slidably installed on the cross-frame 6. An elevating plate 72 is slidably installed on the module slide plate 71. The elevating plate 72 is connected with a sliding drive.

Two clamping plates 74 are symmetrically arranged at the output end of the clamping jaw cylinder 73, and the clamping plates 74 are used for clamping the core.

[0058] Among them, the module slide plate 71 is rectangular plate-shaped and fixedly connected to the output end of the linear module 701. The module slide plate 71 is fixedly connected with a cylinder mounting seat 702. A lifting cylinder 703 is installed on the cylinder mounting seat 702 as the sliding drive of the elevating plate 72. The output end of the lifting cylinder 703 is fixedly connected with a cylinder connecting block 704. The elevating plate 72 includes two rectangular plates arranged in parallel on both sides of the cylinder mounting seat 702. The rectangular plates are slidably connected to the module slide plate 71 through slide rails, and the two rectangular plates are fixedly connected through a connecting plate.

[0059] Combined with the specific use environment, when the present invention is in use: the core to be shaped is placed on the tray 51 and transported to the working range of the transfer component 7 through the wire body 5. The linear module 701 drives the transfer component 7 to the position of the tray 51. The lifting cylinder 703 controls the clamping plate 74 to move downward, and the clamping jaw cylinder 73 controls the clamping plate 74 to grab the core. Then, through the drive of the linear module 701, the core is transferred into the core seat 23.

[0060] The adjusting motor 212 drives the slide plate 21 to approach the iron core seat 23 through the bidirectional lead screw 211. The shaping motor 204 drives the iron core seat 23 to rotate. After the shaping outer cylinder 222 contacts the iron core, the iron core is circumferentially shaped. After the circumferential shaping is completed, the iron core seat 23 stops rotating and the slide plate 21 resets.

[0061] The electric cylinder 303 drives the detection assembly 3 to move downward, so that the upper pressing die 31 presses down the end face of the iron core for axial shaping. Subsequently, the upper pressing die 31 rises a certain distance, and the detection movable plate 321 is driven by the cylinder to drive the detection sensor 32 to move downward. The probe part 323 of the detection sensor 32 contacts the end face of the iron core, and multiple probe parts 323 detect the end face. After the end face is detected to be qualified, the detection assembly 3 resets. The transfer assembly 7 transfers the shaped iron core to the tray 51.
