Description

Technical Field

[0001] This utility model belongs to the field of iron core end face detection technology, and specifically relates to an iron core end face detection mechanism. Background Technology

[0002] In the design of high-efficiency motors, especially new-generation drive motors using flat copper wire windings, the iron core, as the core carrier of the magnetic circuit, directly determines the motor's energy efficiency, power density, and operational stability through its manufacturing quality. Flat copper wire motors, due to their high slot fill factor, excellent heat dissipation performance, and low loss characteristics, are increasingly becoming the preferred solution in fields such as new energy vehicles and high-end industrial drives. These motors have extremely stringent requirements for the machining precision of the iron core, especially the overall flatness of the core's end faces.

[0003] Chinese patent CN115854960A discloses a key dimension detection device for rotor core products, which includes a flatness detection mechanism. This mechanism comprises a sensor assembly mounting frame for mounting sensor components. The mounting frame is a square frame structure, with its sides slidably assembled with a slide rail mechanism located on the inner side of the vertical section of a C-shaped frame. A connecting plate for the sensor assembly mounting frame, connected to a pressure sensor mechanism, is located on the top surface of the mounting frame, and a contact sensor mounting plate is located on the bottom surface. A pressure head is fixedly positioned below the contact sensor mounting plate. The sensor assembly includes 12 signal amplifiers and contact sensors. The 12 signal amplifiers are arranged in parallel on the front side of the mounting frame, and the contact sensors are arranged in pairs and circumferentially fixed to the contact sensor mounting plate. In use, flatness is detected through the contact points of multiple contact sensors. However, in this prior art, the contact sensors are directly fixed to the mounting plate, making it impossible to adjust their positions according to the diameter of the core end face. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a core end face inspection mechanism.

[0005] The technical solution of this utility model is as follows:

[0006] A core end face inspection mechanism includes a truss, an end face inspection component mounted on the truss, and a core seat for driving the core to rise and fall. The end face inspection component includes a motor mounting plate fixed on the truss, a geared motor mounted on the motor mounting plate, and multiple sliding components arranged in a circle with the shaft of the geared motor as the center. The sliding direction of the sliding components is radial to the geared motor. The sliding components are equipped with detection devices. The output shaft of the geared motor is rotatably connected to multiple individual connecting rods that are rotatably connected to the sliding components.

[0007] Furthermore, three evenly distributed extension plates are provided on the peripheral wall of the motor fixing plate, and I-shaped blocks are fixedly installed on the extension plates. The I-shaped blocks are fixedly installed on one side of the truss.

[0008] Furthermore, the sliding assembly includes a slide rail fixed to the bottom of the extension plate, a sensor mounting block slidably connected to the slide rail, the sensor mounting block being rotatably connected to one end of the connecting rod, and a detection device being fixedly mounted on the sensor mounting block.

[0009] Furthermore, the geared motor shaft is coaxially fixedly connected to a turntable located below the motor mounting plate, and the turntable is rotatably connected to one end of the connecting rod.

[0010] Furthermore, the detection device is specifically a contact displacement sensor.

[0011] Furthermore, a core lifting platform is provided at the bottom of the core base.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses a geared motor to drive a sliding component to move radially along the iron core, thereby adjusting the radial displacement of the detection device. This allows for easy adaptation to iron cores of different sizes, and the detection device enables the detection of the iron core end face, ensuring accurate flatness detection.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 3 As shown, a core end face detection mechanism includes a truss 1, an end face detection component 2 disposed on the truss 1, and a core seat 4 for driving the core 3 to rise and fall. The end face detection component 2 includes a motor fixing plate 25 fixed on the truss 1, a reduction motor 22 fixedly installed on the motor fixing plate 25, and a plurality of sliding components distributed in a circle with the axis of rotation of the reduction motor 22 as the center. The sliding direction of the sliding components is the radial direction of the reduction motor 22. Detection devices are disposed on the sliding components. The output shaft of the reduction motor 22 is rotatably connected to a plurality of connecting rods 27 that are individually rotatably connected to the sliding components. The three connecting rods 27 are distributed in a ring array.

[0020] In this embodiment, three evenly distributed extension plates 24 are provided on the peripheral wall of the motor fixing plate 25. The extension plates 24 are integrally formed with the motor fixing plate 25. I-shaped blocks 23 are fixedly installed on the extension plates 24. The I-shaped blocks 23 are fixedly installed on one side of the truss 1.

[0021] In this embodiment, the sliding assembly includes a slide rail 26 fixed to the bottom of the extension plate 24, a sensor mounting block 29 slidably connected to the slide rail 26, a sensor mounting block 29 hinged to one end of the connecting rod 27, and a detection device fixedly mounted on the sensor mounting block 29.

[0022] In this embodiment, the output end of the geared motor 22 extends to the lower part of the motor fixing plate 25, and the rotating shaft of the geared motor 22 is coaxially fixedly connected to the turntable 28 located below the motor fixing plate 25. The turntable 28 is hinged to one end of the connecting rod 27.

[0023] In this embodiment, the detection device is specifically a contact displacement sensor 21.

[0024] In this embodiment, a core lifting platform 5 is provided at the bottom of the core base 4.

[0025] In use, the iron core lifting platform 5 is fixedly installed at a suitable work position according to actual production needs, the truss 1 is fixedly installed on one side of the iron core lifting platform 5, and the end face detection component 2 is fixedly installed on the truss 1 and located above the iron core lifting platform 5.

[0026] Then, according to the size of the iron core 3, the geared motor 22 is controlled to drive the turntable 28 to rotate. The turntable 28 drives the sensor mounting block 29 to move along the slide rail 26 through the connecting rod 27, so that the three contact displacement sensors 21 are adjusted to the appropriate position. After the position is adjusted, the iron core lifting platform 5 lifts the iron core seat 4 until the upper end face of the iron core 3 contacts the detection end of the contact displacement sensor 21, and then transmits the signal to the control end, thereby completing the end face detection of the iron core 3.

[0027] It should be noted that the test by the three contact displacement sensors 21 can reflect whether the end face of the entire iron core 3 is flat, ensuring the accuracy of the test.

[0028] It should be noted that a lifting plate is provided on the top of the iron core lifting platform 5. The lifting plate is fixed with multiple guide shafts that are vertically inserted into the iron core lifting platform 5. The guide shafts are adjusted in height by means of cylinders or other height adjustment components.
