Abstract
Description
Technical Field
[0001] This invention belongs to the field of rotor core processing equipment, and more specifically, relates to a magnet patch tooling for producing rotor cores of articulated motors. Background Technology
[0002] The rotor core is a crucial component of rotating electrical equipment such as electric motors and generators. Located in the rotor section, it is one of the key parts for electromagnetic energy conversion in the motor. Simply put, the rotor core is a structure composed of ferromagnetic material (usually silicon steel sheets) inside the rotor. It guides and enhances the effect of the magnetic field on the rotor, thereby achieving the conversion between electrical energy and mechanical energy. The rotor core typically works in conjunction with the stator core, forming the basis for the normal operation of the motor.
[0003] The main purpose of attaching magnets to the rotor core is to reduce eddy current losses, lower hysteresis losses, protect the core from damage, improve magnetic field distribution, and reduce noise and vibration, thereby improving the efficiency and operational stability of the motor or generator. Through these effects, the magnets can significantly improve the equipment's performance and extend its service life.
[0004] Currently, there are two types of magnetic sheet mounting: one is manual mounting suitable for small workshops, and the other is automatic mounting equipment (magnet insertion machine, magnet mounting machine) suitable for large-scale production. How to achieve fast and accurate mounting in small workshops is a problem that needs to be solved. Summary of the Invention
[0005] To address the above deficiencies, this invention provides a magnet patching fixture for producing rotor cores of articulated motors, comprising a base plate. An inner support assembly for fixing the core sleeve is installed in the middle of the upper surface of the base plate. A clamping ring is provided outside the inner support assembly. Several clamping assemblies slidably connected to the clamping ring are installed on the upper surface of the base plate. The clamping assemblies press the outer wall of the rotor core by sliding adjustment of their position. Several patching assemblies with adjustable spacing from the rotor core are also installed on the upper surface of the base plate. The patching assemblies press the magnets onto the outer wall of the rotor core by being close to the rotor core.
[0006] Furthermore, the inner support assembly includes a rotating shaft seat rotatably mounted at the center of the base plate, a base fixedly mounted on the top of the rotating shaft seat, and multiple inner support blocks slidably arranged in a circular array on the base. The outer sides of the multiple inner support blocks are limited by sleeved O-rings. An inner support pressure block is fixedly mounted on the top of each inner support block. The shaft core is fixedly mounted at the center of the base. A buffer spring is sleeved on the outside of the shaft core. A sliding sleeve is slidably mounted on the shaft core and located on top of the buffer spring. An inclined support block is fixedly sleeved on the outer surface of the sliding sleeve and has a groove at the bottom to accommodate the buffer spring. A handwheel is threadedly connected to the top of the shaft core.
[0007] The outer side of the base is also equipped with equidistant positioning wheels arranged in a circular array.
[0008] Furthermore, the internal thread on the inner ring of the handwheel and the external thread on the outer surface of the top of the shaft are both trapezoidal threads.
[0009] Furthermore, the clamping assembly includes a guide rail slider II fixed to the upper surface of the base plate, a floating block slidably disposed on the guide rail slider II, a cam follower fixedly mounted on the top of the floating block, a through groove opened on the side of the floating block near the inner support assembly, a compression spring placed between the through groove and the clamping block, and a pressure roller evenly distributed vertically and vertically disposed on the end of the clamping block away from the compression spring.
[0010] Each of the cam followers is slidably mounted in a corresponding groove opened in the clamping ring.
[0011] Furthermore, the inner sidewalls of the through groove are provided with pin grooves, and the clamping block is slidably connected to the two pin grooves through pins on both sides.
[0012] Furthermore, the patch assembly includes a guide rail slider I fixed to the upper surface of the base plate, a push block slidably disposed on the guide rail slider I, a rectangular magnetic slot vertically opened at the working end of the push block for inserting a magnetic sheet, a positioning plug for matching the positioning wheel fixedly installed at the working end of the push block, the positioning plug being located at the bottom of the magnetic slot, and a handle I fixedly installed at the end of the push block away from the magnetic slot.
[0013] Furthermore, the upper surface of the base plate is also equipped with several rolling support plates arranged in a circular array. The rolling support plates are fixed with two guide rollers by two bolts, and the two guide rollers are in contact with the upper surface and the bottom surface of the clamping ring, respectively.
[0014] Furthermore, at least one handle II is fixed to the outer ring of the clamping ring.
[0015] Compared with the prior art, the present invention has the following advantages:
[0016] In the process of manufacturing articulated motors, it is possible to achieve high-precision bonding of magnetic steel sheets to the rotor core, which is suitable for research and development or small-batch production stages, with low production costs and easy operation.
[0017] The overall structure is simple. Through the internal support assembly, clamping assembly and patch assembly, the installation and positioning of the rotor core are realized, as well as the functions of stable adjustment and easy adjustment during patching. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0027] Example
[0028] like Figure 1 As shown, this embodiment provides a magnet patching fixture for producing rotor cores of articulated motors, including a base plate 1, and an inner support assembly 2, a clamping assembly 3, and a patching assembly 5 located on top of the base plate 1 and cooperating with each other;
[0029] like Figures 5 to 6As shown in detail, the inner support assembly 2 includes a rotating shaft seat 21 rotatably mounted at the center of the base plate 1. The rotating shaft seat 21 is rotated manually or mechanically to complete the circumferential patching of the rotor core 10. A base 22 is fixedly mounted on the top of the rotating shaft seat 21. Multiple inner support blocks 23 are slidably arranged in a ring array on the base 22. The outer sides of the multiple inner support blocks 23 are provided with slots at the same horizontal height. O-rings 24 are sleeved on the outside of the inner support blocks 23 and are inserted into each slot, thereby realizing the reset function of each inner support block 23 through the O-rings 24.
[0030] An inner support block 25 is fixedly installed on the top of each inner support block 23. The shaft core 26 is fixedly installed in the center of the base 22. The buffer spring 27 is sleeved on the outside of the shaft core 26. The sliding sleeve 28 is slidably disposed on the shaft core 26 and located on top of the buffer spring 27. The inclined support block 29 is fixedly sleeved on the outer surface of the sliding sleeve 28 and has a groove at the bottom to accommodate the buffer spring 27. The top of the shaft core 26 is threadedly connected to a handwheel 210. It should be noted that the internal thread inside the handwheel 210 and the external thread at the top of the shaft core 26 are both trapezoidal threads. The trapezoidal threads enable the sliding sleeve 28 to slide normally up and down on the shaft core 26, ensuring smooth up and down sliding.
[0031] A series of equidistant, circularly arranged positioning wheels 211 are rotatably mounted on the outer side of the bottom of the base 22. These wheels cooperate with the positioning insert 55 to ensure the accuracy of the patch placement. A guide block 212 is provided at the midpoint between every two adjacent inner support blocks 23. The guide block 212 is fixed to the upper surface of the base 22 and serves to guide the rotor core 10 during installation. In addition, multiple inner sliders 213 arranged in a circular array are fixedly mounted on the base 22. The inner support blocks 23 are slidably mounted on the inner sliders 213. (Details are as follows...) Figure 7 As shown, the inner slider 213 is T-shaped, and the inner wall of the inner support block 23 is provided with a T-shaped groove for the inner slider 213 to be inserted, which can realize the stable sliding of the inner support block 23.
[0032] like Figures 2 to 3As shown, the clamping assembly 3 includes a guide rail slider II 31 fixed to the upper surface of the base plate 1, a floating block 32 slidably mounted on the guide rail slider II 31, a cam follower 33 fixedly mounted on the top of the floating block 32, and a through groove 34 opened on the side of the floating block 32 near the inner support assembly 2. A compression spring 35 is placed between the through groove 34 and the clamping block 36, which has a rebound function. At the same time, the non-connected structure facilitates disassembly. In addition, the inner sidewalls of the through groove 34 are provided with pin grooves 37, and the clamping block 36 passes through two... The pin 38 on the side is slidably connected to the two pin slots 37, and the end of the clamping block 36 away from the compression spring 35 is rotatably provided with pressure rollers 39 evenly distributed vertically. When the clamping block 36 is placed in the through groove 34, the pin 38 is inserted into the clamping block 36 through the pin slot 37. In conjunction with the compression spring 35, it plays a certain buffering role when the pressure rollers 39 abut against the outer wall of the rotor core 10. The setting of the pin 38 prevents the clamping block 36 from slipping out of the through groove 34, and also facilitates the disassembly and assembly of the clamping block 36 and the compression spring 35.
[0033] Each cam follower 33 is slidably installed in the corresponding groove 11 opened in the clamping ring 4. The number of grooves 11 is the same as the number of cam followers 33. The grooves 11 can realize the back-and-forth sliding of the clamping assembly 3 to achieve the purpose of clamping the rotor core 10.
[0034] like Figure 4 As shown, the patch assembly 5 includes a guide rail slider I51 fixed to the upper surface of the base plate 1, a push block 52 slidably disposed on the guide rail slider I51, a rectangular magnetic slot 53 vertically opened at the working end of the push block 52 for the insertion of the magnetic sheet 54, a positioning insert 55 for matching the positioning wheel 211 is also fixedly installed at the working end of the push block 52, the positioning insert 55 is located at the bottom of the magnetic slot 53, and a handle I56 is fixedly installed at the end of the push block 52 away from the magnetic slot 53 for easy rotation of the push block 52;
[0035] It should be noted that when attaching the magnetic steel sheet 54, the clamping assembly 3 and the inner support assembly 2 first position the rotor core 10. When the pushing block 52 approaches the rotor core 10, the positioning insert 55 first engages with the positioning wheel 211 at the corresponding position on the base 22 to ensure the accuracy of the attaching work.
[0036] In addition, several rolling support plates 6 arranged in a ring array are installed on the upper surface of the base plate 1. The rolling support plates 6 are fixed with two guide rollers 7 by two bolts. The two guide rollers 7 are in contact with the upper and bottom surfaces of the clamping ring 4 respectively, which facilitates the rotation of the clamping ring 4. The clamping ring 4 can be pushed by the handle II8 fixed on the outer ring of the clamping ring 4.
[0037] The magnet patch tooling for producing a joint motor rotor core described in this embodiment first involves placing the rotor core 10 onto the inner support assembly 2. Then, rotating the handwheel 210 in the inner support assembly 2 causes the handwheel 210 to push the sliding sleeve 28 downward, and the inclined support block 29 pushes the inner support block 23 outward, so that the inner support block 23 supports the inner wall of the rotor core 10, and the inner support pressure block 25 presses against the end of the rotor core 10, thereby positioning the rotor core 10.
[0038] Subsequently, the clamping ring 4 is rotated, causing multiple clamping components 3 to move closer to the rotor core 10 in sync. That is, the floating block 32 is driven by the cam follower 33, so that the pressure roller 39 abuts against the outer wall of the rotor core 10 as the clamping block 36 is adjusted.
[0039] Finally, the magnet 54 is inserted into the magnet slot 53 of the push block 52, and a layer of glue is evenly applied to the outer wall of the magnet 54. The push block 52 is pushed to move closer to the rotor core 10. The positioning block 55 on the push block 52 is engaged with the positioning wheel 211 at the corresponding position on the bottom of the base 22, ensuring that the magnet 54 is accurately pressed onto the outer wall of the rotor core 10, thereby achieving precise patching.
[0040] After the first magnet sheet 54 is attached, the clamping assembly 3 releases its contact with the rotor core 10, and the rotating shaft seat 21 drives the entire inner support assembly 2 to rotate, which facilitates the attachment of the magnet sheet to the next position on the outer wall of the rotor core 10. This process is repeated until all magnet sheets 54 are attached.
[0041] It should be noted that the structure described in this invention can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the description and drawings of this invention, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this invention.
