Description

Technical Field

[0001] This utility model relates to the technical field of motor assembly equipment, and specifically to a motor rotor assembly commutation device. Background Technology

[0002] The rotor assembly mainly includes a rotor core, a spindle passing through the rotor shaft hole, and a commutator mounted on the spindle. Currently, in the subsequent processing of the rotor assembly, there are certain directional requirements for the rotor assembly. That is, the end with the commutator must always be kept in the same direction in order to perform the correct assembly work.

[0003] However, since one rotor assembly is a rotating body, there may be excess rotation during the feeding process, which can cause the rotor assembly to become disoriented. Therefore, it is easy to cause incorrect feeding direction after feeding.

[0004] Therefore, there is an urgent need for a technology that can reverse the direction of the rotor assembly when an directional error occurs. Utility Model Content

[0005] One objective of this utility model is to provide a commutation device for a motor rotor assembly to solve the aforementioned technical problems. The present utility model adopts the following technical solution: A motor rotor assembly commutation device includes a base, on which a driving gear and a driven gear mesh with each other are disposed, and a drive mechanism that is connected to the driving gear and drives it to rotate is also disposed on the base. A jig seat for mounting the rotor assembly is formed on the driving gear, and the jig seat is provided with a positioning structure for assembling the rotor assembly therein. A limiting plate is also disposed on the driven gear, and the limiting plate is used to limit the rotor assembly during assembly.

[0006] Furthermore, a positioning groove for placing the rotor assembly is formed on the end face of the fixture base, the inner wall of the positioning groove is set as a curved surface that is square with the circumferential surface of the rotor assembly, and the positioning structure is disposed within the positioning groove.

[0007] Furthermore, the positioning structure includes a mounting groove formed within the positioning groove, and a magnetic suction element installed within the mounting groove for adsorbing the rotor assembly within the positioning groove.

[0008] Furthermore, the depth of the positioning groove is less than the radius of the rotor assembly.

[0009] Furthermore, one end of the limiting plate is detachably connected to the driven gear, and the other end extends toward the positioning groove, and the end of the extended end of the limiting plate is provided with a surface in the shape of an arc.

[0010] Furthermore, a limiting groove extending along the length of the limiting plate is formed on the limiting plate. The limiting groove is a countersunk groove. The limiting plate is detachably connected to the driven gear by bolts, and the bolts can be limited to move along the limiting groove.

[0011] Furthermore, a mounting base is fixedly provided on the driven gear, and the mounting base has a threaded hole for threaded connection with a bolt, so that the limiting plate is mounted on the mounting base by bolts.

[0012] Furthermore, the seat body includes: Base; A slide table, which is fixedly mounted on the base; A base plate is fixedly mounted on the slide table and moves back and forth with the slide table. The driving gear and the driven gear are rotatably connected to the base plate, and the drive mechanism is fixedly mounted on the base plate to drive the driving gear to rotate.

[0013] Furthermore, the driving mechanism is a rotary cylinder.

[0014] Furthermore, the gear ratio between the driving gear and the driven gear is 1.

[0015] The beneficial effects of this utility model are as follows: When a positional error occurs during the loading of the rotor assembly, the end of the spindle equipped with the commutator faces the driven gear. At this time, the drive mechanism drives the driving gear to rotate, and after rotating 180°, the rotor assembly is reversed. This will drive the driven gear to rotate synchronously at the same speed. After the reversal is completed and the rotor assembly is removed from the fixture, the drive mechanism drives the driving gear to rotate 180° again, thereby restoring the fixture and the limiting plate to their initial positions. By setting the gear ratio of the driving gear and the driven gear to 1, the two gears can have the same speed. This ensures that after multiple rotations, the position of the limiting plate relative to the corresponding fixture remains unchanged, thus avoiding positional deviations that could affect the limiting operation of the rotor assembly.

[0016] This utility model provides an electronic rotor assembly reversing device, which is used to reverse the direction of the loaded rotor assembly during the assembly process, so that the rotor assembly can always keep in the same direction and avoid the situation of direction confusion affecting subsequent production.

[0020] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0021] This utility model provides an electronic rotor assembly reversing device, which is used to reverse the direction of the loaded rotor assembly during the assembly process, so that the rotor assembly can always keep in the same direction and avoid the situation of direction confusion affecting subsequent production.

[0022] like Figure 1-2 As shown, this embodiment provides a motor rotor assembly reversing device, including a base 100, on which a driving gear 101 and a driven gear 102 mesh with each other, and a driving mechanism 103 that is connected to the driving gear 101 to drive its rotation is also provided on the base 100. A jig seat 200 for mounting the rotor assembly is formed on the driving gear 101, and the jig seat 200 is provided with a positioning structure for assembling the rotor assembly therein. A limiting plate 300 is also provided on the driven gear 102, and the limiting plate 300 is used to limit the rotor assembly during assembly. In this embodiment, the drive mechanism 103 is implemented by a rotary cylinder. In order to ensure normal operation during the assembly and reversal of the rotor assembly and avoid mutual interference, the gear ratio of the drive gear 101 and the driven gear 102 is set to 1, so that the two gears have the same rotational speed. This ensures that the limiting plate 300 is always kept in the same position relative to the fixture seat 200, which facilitates the limiting of the rotor assembly. At the same time, when the drive gear 101 and the driven gear 102 are rotating, the limiting plate 300 and the rotor assembly positioned on the fixture seat 200 will not interfere with each other.

[0023] During the loading and reversing process of the rotor assembly, the loading device transfers the rotor assembly to this device and loads it onto the jig seat 200. The rotor assembly is then limited by the limiting plate 300 on the driven gear 102. Figure 1 Able to know, Figure 1 This is a schematic diagram showing the rotor assembly in the correct orientation after being reversed by this reversing device. At this time, one end of the commutator mounted on the spindle extends outward, and the position of the rotor assembly mounted on the fixture seat 200 is limited by the limiting plate 300. Specifically, it limits the gap between the rotor assembly and the driven gear 102 to be too small, so that during the reversing process, the spindle will interfere with the components on the driven gear 102 during the swinging process.

[0024] When a positional error occurs during the loading of the rotor assembly, the end of the spindle equipped with the commutator faces the driven gear 102. At this time, the drive mechanism 103 drives the drive gear 101 to rotate, and after rotating 180°, the rotor assembly is reversed. This will cause the driven gear 102 to rotate synchronously at the same speed. After the reversal is completed and the rotor assembly is removed from the fixture seat 200, the drive mechanism 103 drives the drive gear 101 to rotate 180° again, thereby restoring the fixture seat 200 and the limiting plate 300 to their initial positions. By setting the gear ratio of the drive gear 101 and the driven gear 102 to 1, the two gears can have the same speed. This ensures that after multiple rotations, the position of the limiting plate 300 relative to the corresponding fixture seat 200 remains unchanged, thus avoiding positional deviations that could affect the limiting operation of the rotor assembly.

[0025] In this embodiment, in order to reliably fix the rotor assembly and achieve high stability during commutation, such as... Figure 2 As shown, a positioning groove 201 is formed on the end face of the fixture base 200 to hold the rotor assembly. The inner wall of the positioning groove 201 is a curved surface that is square with the circumferential surface of the rotor assembly, and the positioning structure is set within the positioning groove 201. That is to say, when the rotor assembly is installed in the positioning groove 201, the rotor assembly can be fixed by the arc shape of the positioning groove 201 and the inner wall that conforms to the outline of the rotor assembly. During the rotation and reversal process, the inner wall of the positioning groove 201 can reliably limit the rotor assembly and prevent it from swinging along the axis of the drive gear 101, thereby ensuring the reliability of the rotor assembly reversal.

[0026] In this technical solution, the positioning structure is used to reliably hold the rotor assembly on the fixture seat 200. The positioning structure includes a mounting groove 202 formed in the positioning groove 201, and a magnetic suction member installed in the mounting groove 202 to attract the rotor assembly into the positioning groove 201.

[0027] In other words, the rotor assembly is positioned in the positioning groove 201 by magnetic attraction, which ensures that the rotor assembly is reliably installed in the positioning groove 201. At the same time, it is also convenient to remove the rotor assembly smoothly from the positioning groove 201. Furthermore, the structure for fixing the rotor assembly is relatively simple and reliable.

[0028] In this embodiment, to prevent the jig disk from interfering with the limiting plate 300 and causing a collision during the meshing and rotation of the driving gear 101 and the driven gear 102, the groove depth of the positioning groove 201 is smaller than the radius of the rotor assembly.

[0029] In other words, when the limiting plate 300 limits the rotor assembly, the limiting plate 300 and the rotor assembly abut against each other. Specifically, the end of the limiting plate 300 abuts against the end of the iron core in the rotor assembly. At this time, the groove depth of the positioning groove 201 is set to be less than the radius of the rotor assembly, which means that most of the iron core is outside the positioning groove 201. The limiting plate 300 can limit the rotor assembly by abutting against the part of the iron core located outside the positioning groove 201. In this state, when the driving gear 101 and the driven gear 102 rotate relative to each other, the limiting plate 300 will not interfere with the fixture plate, ensuring the smoothness of the commutation action of the rotor assembly.

[0030] In this embodiment, when the limiting plate 300 and the rotor assembly abut against each other to complete the limiting, in order to facilitate the mutual rotation of the driving gear 101 and the driven gear 102, and to achieve a smooth transition between the limiting plate 300 and the rotor assembly, in this technical solution, one end of the limiting plate 300 is detachably connected to the driven gear 102, and the other end extends toward the positioning groove 201, and the end of the extended end of the limiting plate 300 is provided with a surface with an arc-shaped curved surface.

[0031] When the county committee office and the rotor assembly come into contact with each other to limit the rotor assembly, when the rotor assembly is reversed, the drive gear 101 rotates under the drive of the drive mechanism 103 and drives the rotor assembly to swing. At this time, by setting the extended end of the limit plate 300 with an arc surface, the limit plate 300 and the rotor assembly can smoothly transition and separate from each other during the swinging process.

[0032] In this embodiment, in order to adjust the limiting position of the limiting plate 300, a limiting groove 301 extending along the length direction of the limiting plate 300 is formed on the limiting plate 300. The limiting groove 301 is a countersunk groove. The limiting plate 300 is detachably connected to the driven gear 102 by bolts, and the bolts can move along the limiting groove 301. By loosening the bolts, the position of the limiting plate 300 can be adjusted, thereby adjusting the limiting position of the rotor assembly to adapt to limiting different rotor assemblies.

[0033] Meanwhile, to facilitate the installation of the limiting plate 300, a mounting base 302 is fixedly installed on the driven gear 102. The mounting base 302 has threaded holes for bolt thread connection, allowing the limiting plate 300 to be mounted on the mounting base 302 by bolts. By raising the position of the limiting plate 300 with the mounting base 302, it is easier to install the limiting plate 300. At the same time, since the mounting base 302 raises the height of the limiting plate 300 relative to the driven gear 102, it can further increase the distance between the limiting plate 300 and the bottom of the positioning groove 201. This can further reduce the probability of mutual interference between the fixture plate and the limiting plate 300.

[0034] In this embodiment, in order to further improve the adaptability of this reversing device by understanding the overall positional relationship of the two gears, specifically, as follows: Figure 2 As shown, the seat 100 includes a base 110, a slide 120, and a base plate 130. The slide 120 is fixedly mounted on the base 110. The base plate 130 is fixedly mounted on the slide 120 and moves back and forth with the slide 120. The drive gear 101 and the driven gear 102 are rotatably connected to the base plate 130. The drive mechanism 103 is fixedly mounted on the base plate 130 to drive the drive gear 101 to rotate.

[0035] In other words, the position of the base plate 130 and the two gears and drive mechanism 103 mounted on the base plate 130 can be adjusted by the slide table 120, so as to adjust the position in the machining system and improve the adaptability of this reversing device.

[0036] It is worth noting that in this embodiment, the slide table 120 can be implemented using technical solutions known in the prior art. In this embodiment, a manual slide table 120 is used, such as a new digital display positioning slide table disclosed in announcement number CN213673821U. The position of the base plate 130 can be adjusted by the manual slide table 120, thereby achieving adaptability to the entire processing system.

Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
